Best Mode for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. First, referring to FIGS. 1 to 58, as a first embodiment, an embodiment in which the present invention is applied to a pachinko game machine (hereinafter simply referred to as "pachinko machine") 10 will be described. FIG. 1 is a front view of the pachinko machine 10 in the first embodiment, FIG. 2 is a front view of the game board 13 of the pachinko machine 10, and FIG. 3 is a rear view of the pachinko machine 10.

[0013] In the following description, with respect to the pachinko machine 10 in the state shown in FIG. 1, the front side of the paper is defined as the front (front) side, and the back side of the paper is defined as the rear (back) side for explanation. Also, with respect to the pachinko machine 10 in the state shown in FIG. 1, the upper side is defined as the upper (up) side, the lower side is defined as the lower (down) side, the right side is defined as the right (right) side, and the left side is defined as the left (left) side for explanation. Further, the arrows U-D, L-R, F-B in the figure (for example, see FIG. 2) indicate the vertical direction, horizontal direction, and front-rear direction of the pachinko machine 10, respectively.

[0014] As shown in FIG. 1, the pachinko machine 10 includes an outer frame 11 whose outer shell is formed by a wooden frame combined in a substantially rectangular shape, and an inner frame 12 formed in substantially the same outer shape as the outer frame 11 and supported so as to be openable and closable with respect to the outer frame 11. On the outer frame 11, metal hinges 18 are attached at two upper and lower positions on the left side in a front view (see FIG. 1) to support the inner frame 12, and the inner frame 12 is supported so as to be openable and closable to the front near side with the side where the hinge 18 is provided as the axis of opening and closing.

[0015] On the inner frame 12, a game board 13 (see FIG. 2) having a large number of nails, winning holes 63, 64, etc. is detachably attached from the back side. A pinball game is performed by balls (game balls) flowing down the front of the game board 13. Note that on the inner frame 12, a ball launching unit 112a (see FIG. 4) for launching balls into the front area of the game board 13 and a launching rail (not shown) for guiding the balls launched from the ball launching unit 112a to the front area of the game board 13 are attached.

[0016] On the front side of the inner frame 12, a front frame 14 covering the upper front thereof and a lower dish unit 15 covering the lower side thereof are provided. Metal hinges 19 are attached at two upper and lower positions on the left side in a front view (see FIG. 1) to support the front frame 14 and the lower dish unit 15, and the front frame 14 and the lower dish unit 15 are supported so as to be openable and closable to the front near side with the side where the hinge 19 is provided as the axis of opening and closing. Note that the locking of the inner frame 12 and the locking of the front frame 14 are respectively released by inserting a dedicated key into the keyhole 21 of the cylinder lock 20 and performing a predetermined operation.

[0017] The front frame 14 is assembled with resin parts for decoration, electrical parts, etc., and a window portion 14c formed in a substantially elliptical shape is provided at a substantially central portion thereof. A glass unit 16 having two plate glasses is disposed on the back side of the front frame 14, and the front of the game board 13 can be visually recognized on the front side of the pachinko machine 10 through the glass unit 16.

[0018] On the front frame 14, an upper tray 17 for storing balls is formed in a substantially box shape that projects forward and has an open top surface. Prize balls, lent balls, etc. are discharged onto this upper tray 17. The bottom surface of the upper tray 17 is formed with a downward slope on the right side when viewed from the front (see Fig. 1), and due to this slope, the balls thrown into the upper tray 17 are guided to the ball launch unit 112a (see Fig. 4). Also, a frame button 22 is provided on the upper surface of the upper tray 17. This frame button 22 is operated by the player, for example, when changing the stage of the effect displayed on the third symbol display device 81 (see Fig. 2) or when changing the content of the super reach effect.

[0019] On the front frame 14, light emitting means such as various lamps are provided around its periphery (for example, at the corner portions). These light emitting means are controlled to change the light emitting mode by lighting or flashing in response to changes in the gaming state during a big win or a predetermined reach, etc., and play a role in enhancing the effect of the performance during the game. Around the periphery of the window portion 14c, decorative parts 29 - 33 incorporating light emitting means such as LEDs are provided. In the pachinko machine 10, these decorative parts 29 - 33 function as effect lamps such as big win lamps, and during a big win or a reach performance, etc., each of the decorative parts 29 - 33 lights up or flashes by the lighting or flashing of the built-in LEDs, notifying that it is during a big win or during a reach just before a big win. Also, on the upper left portion of the front frame 14 when viewed from the front (see Fig. 1), a display lamp 34 incorporating light emitting means such as LEDs is provided, which can display when a prize ball is being paid out and when an error occurs.

[0020] Also, on the lower side of the right decorative part 32, a small window 35 is formed by attaching a transparent resin from the back side so that the back side of the front frame 14 can be seen, and certificates, etc. pasted in the pasting space K1 on the front of the game board 13 (see Fig. 2) can be viewed from the front of the pachinko machine 10. Also, in the pachinko machine 10, a plating member 36 made of ABS resin with chrome plating is attached to the area around the decorative parts 29 - 33 in order to create a more brilliant atmosphere.

[0021] Below the window portion 14c, a ball lending operation unit 40 is disposed. The ball lending operation unit 40 is provided with a frequency display unit 41, a ball lending button 42, and a return button 43. When the ball lending operation unit 40 is operated with a bill, a card, or the like inserted into a card unit (ball lending unit) (not shown) disposed on the side of the pachinko machine 10, balls are lent according to the operation. Specifically, the frequency display unit 41 is an area where balance information of a card or the like is displayed, and the built-in LED lights up and the balance is displayed numerically as balance information. The ball lending button 42 is operated to obtain lent balls based on information recorded on a card or the like (recording medium), and lent balls are supplied to the upper tray 17 as long as there is a balance on the card or the like. The return button 43 is operated when requesting the return of a card or the like inserted into the card unit. In the case of a pachinko machine, so-called a cash machine, in which balls are directly lent from a ball lending device or the like to the upper tray 17 without passing through the card unit, the ball lending operation unit 40 is not required. In this case, a decorative sticker or the like may be added to the installation portion of the ball lending operation unit 40 so that the component configuration is common. The pachinko machine using the card unit and the cash machine can be made common.

[0022] In the lower tray unit 15 located below the upper tray 17, a lower tray 50 for storing balls that could not be completely stored in the upper tray 17 is formed in a substantially box shape with an open upper surface on the left side thereof. On the right side of the lower tray 50, an operation handle 51 operated by a player to drive the balls into the front of the game board 13 is disposed.

[0023] Inside the operation handle 51, there are built-in a touch sensor 51a for permitting the driving of the ball launch unit 112a, a launch stop switch 51b for stopping the launch of the ball during the period of the pressing operation, a variable resistor (not shown) for detecting the rotation operation amount (rotation position) of the operation handle 51 by the change in the electric resistance, and the like. When the operation handle 51 is rotationally operated clockwise by the player, the touch sensor 51a is turned on and the resistance value of the variable resistor changes corresponding to the rotation operation amount, and the ball is launched with the strength (launch strength) corresponding to the resistance value of the variable resistor, and thereby the ball is driven into the front surface of the game board 13 with the flying amount corresponding to the operation of the player. Further, in a state where the operation handle 51 is not operated by the player, the touch sensor 51a and the launch stop switch 51b are turned off.

[0024] At the lower front part of the lower tray 50, a ball extraction lever 52 for operating when discharging the balls stored in the lower tray 50 downward is provided. This ball extraction lever 52 is constantly biased in the right direction, and by sliding it leftward against the bias, the bottom opening formed in the bottom surface of the lower tray 50 is opened, and the balls naturally fall and are discharged from the bottom opening. The operation of this ball extraction lever 52 is usually performed in a state where a box (generally called a "senryou box") for receiving the balls discharged from the lower tray 50 is placed below the lower tray 50. The operation handle 51 is disposed on the right side of the lower tray 50, and an ashtray 53 is attached to the left side of the lower tray 50.

[0025] As shown in FIG. 2, the game board 13 is configured by assembling a base plate 60 machined into a substantially square shape in a front view, a number of nails (not shown) and windmills (not shown) for guiding the balls, rails 61, 62, a general winning opening 63, a first winning opening 64, a second winning opening 640, a variable winning device 65, a through gate 67, a variable display device unit 80, etc. on the back surface side (or the front surface side) of the inner frame 12 (see FIG. 1).

[0026] The base plate 60 is formed from a wooden board member. The general winning opening 63, the first winning opening 64, the second winning opening 640, and the variable display device unit 80 are disposed in through holes (see, for example, FIG. 5) formed in the base plate 60 by routing, and are fixed from the front side of the game board 13 with tapping screws or the like. Note that the base plate 60 may be made of a light-transmissive resin material. In this case, it becomes possible for the player to visually recognize various structures disposed on the back side of the base plate 60 from the front side thereof.

[0027] The front central portion of the game board 13 can be visually recognized from the front side of the inner frame 12 through the window portion 14c (see FIG. 1) of the front frame 14. Hereinafter, the configuration of the game board 13 will be described mainly with reference to FIG. 2.

[0028] An outer rail 62 formed by bending a strip-shaped metal plate into a substantially arc shape is planted on the front surface of the game board 13, and an arc-shaped inner rail 61 formed of a strip-shaped metal plate similar to the outer rail 62 is planted at a position inside the outer rail 62. The front outer periphery of the game board 13 is surrounded by the inner rail 61 and the outer rail 62, and the front and back are surrounded by the game board 13 and the glass unit 16 (see FIG. 1), so that a game area where the game is played by the behavior of the ball is formed on the front surface of the game board 13. The game area is an area (an area where a winning opening or the like is disposed and the launched ball flows down) partitioned by the two rails 61, 62 on the front surface of the game board 13 and a resin outer edge member 73 connecting between the rails.

[0029] The two rails 61, 62 are provided to guide the ball launched from the ball launching unit 112a (see FIG. 4) to the upper part of the game board 13. A return ball prevention member 68 is attached to the tip portion (the upper left portion in FIG. 2) of the inner rail 61, and a situation where the ball once guided to the upper part of the game board 13 returns into the ball guide passage again is prevented. A return rubber 69 is attached to the tip portion (the upper right portion in FIG. 2) of the outer rail 62 at a position corresponding to the maximum flight portion of the ball, and the ball launched with a momentum above a predetermined level hits the return rubber 69 and bounces back toward the central portion side while the momentum is attenuated.

[0030] In the lower left part of the front view of the gaming area (the lower left part of FIG. 2), there are provided first symbol display devices 37A and 37B each including a plurality of LEDs as light emitting means and a 7-segment display. The first symbol display devices 37A and 37B are configured to display according to each control performed by the main control device 110 (see FIG. 4), and mainly display the gaming state of the pachinko machine 10. In the present embodiment, the first symbol display devices 37A and 37B are configured to be selectively used according to whether the ball wins the first winning port 64 or the second winning port 640. Specifically, when the ball wins the first winning port 64, the first symbol display device 37A operates, while when the ball wins the second winning port 640, the first symbol display device 37B operates.

[0031] Also, the first symbol display devices 37A and 37B use the LEDs to indicate whether the pachinko machine 10 is in the probability-variable state, time-saving state, or normal state by the lighting state, whether it is in the variable state by the lighting state, whether the stop symbol corresponds to a probability-variable jackpot, a normal jackpot, or a non-winning symbol by the lighting state, indicate the number of hold balls by the lighting state, and perform the number of rounds during the jackpot and error display by the 7-segment display device. Note that the plurality of LEDs are configured such that the emission colors of the respective LEDs (for example, red, green, blue) are different, and various gaming states of the pachinko machine 10 can be suggested with a small number of LEDs by the combination of the emission colors.

[0032] In addition, in this pachinko machine 10, a lottery is performed when the ball wins the first winning port 64 and the second winning port 640. The pachinko machine 10 performs a winning / losing determination (jackpot lottery) as to whether it is a jackpot in the lottery, and also determines the jackpot type when it is determined to be a jackpot. As the jackpot types determined here, there are prepared a 15R probability-variable jackpot, a 4R probability-variable jackpot, and a 15R normal jackpot. The first symbol display devices 37A and 37B not only show whether the result of the lottery is a jackpot as the stop symbol after the variation ends, but also show a symbol corresponding to the jackpot type when it is a jackpot.

[0033] Here, the "15R certain-variation jackpot" refers to a certain-variation jackpot where, after a jackpot with a maximum round number of 15 rounds, it transitions to a high-probability state. The "4R certain-variation jackpot" refers to a certain-variation jackpot where, after a jackpot with a maximum round number of 4 rounds, it transitions to a high-probability state. Also, the "15R normal jackpot" is a jackpot where, after a jackpot with a maximum round number of 15 rounds, it transitions to a low-probability state and enters a time-saving state for a predetermined number of fluctuations (e.g., 100 fluctuations).

[0034] Also, the "high-probability state" refers to a state where, after the jackpot ends, the probability of the subsequent jackpot increases as an added value, that is, during so-called probability variation (while the certain variation is in progress). In other words, it is the state of a game where it is easy to transition to a special game state. The high-probability state (while the certain variation is in progress) in this embodiment includes a game state where the winning probability of the second symbol described later increases and balls are likely to win at the second winning opening 640. The "low-probability state" refers to when the certain variation is not in progress, that is, a state where the jackpot probability is in the normal state, namely, a state where the jackpot probability is lower than during the certain variation. Also, the time-saving state (while time-saving is in progress) among the "low-probability states" refers to a game state where the jackpot probability is in the normal state and, while the jackpot probability remains the same, only the winning probability of the second symbol increases and balls are likely to win at the second winning opening 640. On the other hand, when the pachinko machine 10 is in the normal state, it is a game state where neither the certain variation nor the time-saving is in progress (a state where neither the jackpot probability nor the winning probability of the second symbol has increased).

[0035] During the certain variation or while time-saving is in progress, not only does the winning probability of the second symbol increase, but also the time when the electric accessory 640a associated with the second winning opening 640 is opened is changed, and a longer time is set compared to the normal state. When the electric accessory 640a is in the open state, balls are more likely to win at the second winning opening 640 compared to when the electric accessory 640a is in the closed state. Therefore, during the certain variation or while time-saving is in progress, it becomes a state where balls are likely to win at the second winning opening 640, and the number of times the jackpot lottery is conducted can be increased.

[0036] In addition, during the probability variation or time shortening, instead of changing the opening time of the electric accessory 640a associated with the second winning port 640, or in addition to changing the opening time, a change may be made to increase the number of times the electric accessory 640a opens per hit compared to normal. Also, during the probability variation or time shortening, the winning probability of the second symbol may not be changed, and at least one of the time when the electric accessory 640a associated with the second winning port 640 is opened and the number of times the electric accessory 640a opens per hit may be changed. Further, during the probability variation or time shortening, the time when the electric accessory 640a associated with the second winning port 640 is opened and the number of times the electric accessory 640a is opened per hit may not be changed, and only the winning probability of the second symbol may be changed to be higher than that during normal times.

[0037] In the game area, a plurality of general winning ports 63 are provided, where when a ball wins, 5 to 15 balls are paid out as prize balls. Also, in the central part of the game area, a variable display device unit 80 is provided. In the variable display device unit 80, a third symbol display device 81 composed of a liquid crystal display (hereinafter simply abbreviated as "display device") that performs a variable display of the third symbol while synchronizing with the variable display in the first symbol display devices 37A and 37B triggered by a winning (starting winning) at the first winning port 64 and the second winning port 640, and a second symbol display device (not shown) composed of LEDs that perform a variable display of the second symbol triggered by the passage of a ball through the through gate 67 are provided. Also, in the variable display device unit 80, a center frame 86 is provided so as to surround the third symbol display device 81 when viewed from the front.

[0038] The third symbol display device 81 is composed of a large liquid crystal display with a size of about 9 inches to 19 inches. The display content is controlled by a display control device 114 (see FIG. 4), and for example, three symbol columns, namely, an upper, a middle, and a lower one, are displayed. Each symbol column is composed of a plurality of symbols (the third symbols). These third symbols scroll horizontally for each symbol column, and the third symbols are variably displayed on the display screen of the third symbol display device 81. The third symbol display device 81 of the present embodiment performs a decorative display according to the display of the first symbol display devices 37A and 37B, while the display of the game state accompanying the control of the main control device 110 (see FIG. 4) is performed by the first symbol display devices 37A and 37B. Note that instead of a display device, for example, a reel or the like may be used to configure the third symbol display device 81.

[0039] The second symbol display device performs a variable display in which the symbols of "○" and "×" as display symbols (second symbols (not shown)) are alternately lit for a predetermined time every time the ball passes through the through gate 67. In the pachinko machine 10, when it is detected that the ball has passed through the through gate 67, a winning lottery is conducted. As a result of the winning lottery, if it is a win, in the second symbol display device, the symbol of "○" is stopped and displayed after the variable display of the second symbol. Also, as a result of the winning lottery, if it is a miss, in the second symbol display device, the symbol of "×" is stopped and displayed after the variable display of the third symbol.

[0040] The pachinko machine 10 is configured such that when the variable display in the second symbol display device stops at a predetermined symbol (in this embodiment, the symbol of "○"), the electric accessory 640a associated with the second winning opening 640 is in an operating state (opened) for a predetermined time.

[0041] The time taken for the variable display of the second symbol is set to be shorter during probability increase or time limit than when the game state is normal. As a result, during probability increase and time limit, since the variable display of the second symbol is performed in a short time, more winning draws can be conducted than during normal times. Therefore, since the chance of winning in the winning draw increases, more opportunities for the electric accessory 640a of the second winning port 640 to be in the open state can be given to the player. Thus, during probability increase and time limit, it is possible to make the state such that balls are likely to win the second winning port 640.

[0042] In addition, during probability increase or time limit, if the state is made such that balls are likely to win the second winning port 640 by other methods such as increasing the winning probability, increasing the opening time or the number of opening times of the electric accessory 640a for one win, etc., the time taken for the variable display of the second symbol may be made constant regardless of the game state. On the other hand, when setting the time taken for the variable display of the second symbol to be shorter during probability increase or time limit than during normal times, the winning probability may be made constant regardless of the game state, or the opening time or the number of opening times of the electric accessory 640a for one win may be made constant regardless of the game state.

[0043] The through gate 67 is assembled to the game board 13 in the right area of the variable display device unit 80 and is configured so that a part of the balls launched onto the game board 13 can pass through. When a ball passes through the through gate 67, a winning draw for the second symbol is conducted. After the winning draw, a variable display is performed on the second symbol display device. If the result of the winning draw is a win, the symbol "○" is displayed as the stopped symbol of the variable display, and if the result of the winning draw is a miss, the symbol "×" is displayed as the stopped symbol of the variable display.

[0044] The total number of times a ball can pass through the through gate 67 is held up to a maximum of 4 times. The number of held-up balls is displayed by the above-described first symbol display devices 37A and 37B and is also lit and displayed on a second symbol hold lamp (not shown). Four second symbol hold lamps are provided corresponding to the maximum number of holds and are arranged symmetrically left and right below the third symbol display device 81.

[0045] In addition, the variable display of the second symbol is performed by switching on and off a plurality of lamps in the second symbol display device as in the present embodiment, but it may also be performed using a part of the first symbol display devices 37A and 37B and the third symbol display device 81. Similarly, the lighting of the second symbol holding lamp may be performed by a part of the third symbol display device 81.

[0046] Also, the maximum number of balls held for the passage of the ball through the through gate 67 is not limited to four times, and may be set to three times or less, or five times or more (for example, eight times). Also, the number of through gates 67 installed is not limited to one, and may be two, for example.

[0047] Also, the installation position of the through gate 67 is not limited to the right side of the variable display device unit 80, and may be, for example, on the left or right side or below the variable display device unit 80. Also, since the number of balls held is indicated by the first symbol display devices 37A and 37B, the second symbol holding lamp may not perform a lighting display.

[0048] Below the variable display device unit 80, a first winning port 64 into which a ball can win is provided. When a ball wins the first winning port 64, a first winning port switch (not shown) provided on the back side of the game board 13 is turned on, and based on the turning on of the first winning port switch, a jackpot lottery is performed by the main control device 110 (see FIG. 4), and a display corresponding to the lottery result is shown on the first symbol display device 37A.

[0049] On the other hand, below the front view of the first winning port 64, a second winning port 640 into which a ball can win is provided. When a ball wins the second winning port 640, a second winning port switch (not shown) provided on the back side of the game board 13 is turned on, and based on the turning on of the second winning port switch, a jackpot lottery is performed by the main control device 110 (see FIG. 4), and a display corresponding to the lottery result is shown on the first symbol display device 37B.

[0050] In addition, the first winning opening 64 and the second winning opening 640 are each one of the winning openings where when a ball wins, five balls are paid out as prize balls. In this embodiment, the number of prize balls paid out when a ball wins the first winning opening 64 and the number of prize balls paid out when a ball wins the second winning opening 640 are configured to be the same. However, the number of prize balls paid out when a ball wins the first winning opening 64 and the number of prize balls paid out when a ball wins the second winning opening 640 may be different numbers. For example, the number of prize balls paid out when a ball wins the first winning opening 64 may be set to 3, and the number of prize balls paid out when a ball wins the second winning opening 640 may be set to 5.

[0051] An electric accessory 640a is attached to the second winning opening 640. This electric accessory 640a is configured to be openable and closable. Normally, the electric accessory 640a is in a closed state (shrunk state), making it difficult for balls to win the second winning opening 640. On the other hand, when the symbol "○" is displayed on the second symbol display device as a result of the variable display of the second symbol triggered by the passage of a ball through the through gate 67, the electric accessory 640a becomes an open state (expanded state), making it easier for balls to win the second winning opening 640.

[0052] As described above, during certain probability variation and time shortening, the hitting probability of the second symbol is higher and the time taken for the variable display of the second symbol is shorter compared to normal. Therefore, in the variable display of the second symbol, the symbol "○" is more likely to be displayed, and the number of times the electric accessory 640a becomes an open state (expanded state) increases. Furthermore, during certain probability variation and time shortening, the time for which the electric accessory 640a is open is also longer than during normal times. Thus, during certain probability variation and time shortening, a state where it is easier for balls to win the second winning opening 640 can be created compared to normal times.

[0053] Here, the probability of a jackpot is the same whether the ball wins at the first winning opening 64 or at the second winning opening 640, regardless of whether it is in the low-probability state or the high-probability state. However, the probability of getting a 15R probability-variable jackpot selected when a jackpot occurs is set higher when the ball wins at the second winning opening 640 than when the ball wins at the first winning opening 64. On the other hand, the first winning opening 64 does not have an electric accessory 640a like the one at the second winning opening 640, and the ball can always win.

[0054] Therefore, during normal play, the electric accessory 640a associated with the second winning opening 640 is often in the closed state, making it difficult for the ball to win at the second winning opening 640. So, it is more advantageous for the player to aim for the first winning opening 64 without the electric accessory 640a by shooting the ball so that it passes through the left side of the variable display device unit 80 (so-called "left shot") to increase the chance of a jackpot lottery by winning at the first winning opening 64 and aiming for a jackpot.

[0055] On the other hand, during probability-variable play or time-saving play, by passing the ball through the through gate 67, the electric accessory 640a associated with the second winning opening 640 is likely to be in the open state, making it easier for the ball to win at the second winning opening 640. So, it is more advantageous for the player to aim for the second winning opening 640 by shooting the ball so that it passes through the right side of the variable display 80 (so-called "right shot"), passing the ball through the through gate 67 to open the electric accessory 640a and aiming for a 15R probability-variable jackpot by winning at the second winning opening 640.

[0056] Note that, unlike the pachinko machine 10 in this embodiment, when the configuration of the game board 13 is symmetric left and right, it is possible to aim for the first winning opening 64 with a "right shot" or aim for the second winning opening 640 with a "left shot". Therefore, the pachinko machine 10 of this embodiment can eliminate the need to change the way of shooting the ball between "left shot" and "right shot" for the player according to the game state of the pachinko machine 10 (whether it is in probability-variable play, time-saving play, or normal play). Thus, the annoyance of changing the way of shooting the ball can be eliminated.

[0057] On the other hand, in the pachinko machine 10 of the present embodiment, it is configured such that the first winning opening 64 cannot be aimed at during "right shooting", and the balls launched during "left shooting" are configured not to pass through the through gate 67. Therefore, the pachinko machine 10 of the present embodiment can require the player to change the way of launching the balls between "left shooting" and "right shooting" according to the game state of the pachinko machine 10 (whether it is in the probability variation state, time-saving state, or normal state). Thus, it is possible to prevent the game from becoming slow by adding the game property of changing the way of shooting the balls.

[0058] A variable winning device 65 (see FIG. 2) is disposed to the right of the first winning opening 64, and a specific winning opening 65a is provided at a substantially central portion thereof. In the pachinko machine 10, when the jackpot lottery conducted due to winning the first winning opening 64 or the second winning opening 640 results in a jackpot, after a predetermined time (fluctuation time) has elapsed, the first symbol display device 37A or the first symbol display device 37B is lit so as to become the jackpot stop symbol, and the stop symbol corresponding to the jackpot is displayed on the third symbol display device 81 to indicate the occurrence of the jackpot. Thereafter, the game state transitions to a special game state (jackpot) where the balls are likely to win. As this special game state, the specific winning opening 65a, which is normally closed, is opened for a predetermined time (for example, until 30 seconds elapse or until 10 balls win).

[0059] This specific winning opening 65a is closed when the predetermined time has elapsed, and after the closure, the specific winning opening 65a is opened again for the predetermined time. The opening and closing operation of this specific winning opening 65a can be repeated up to, for example, 15 times (15 rounds) at most. The state in which this opening and closing operation is being performed is a form of a special game state advantageous to the player, and a larger number of prize balls are paid out to the player as the imparting of game value (game value) compared to normal times.

[0060] Note that the special game state is not limited to the above-described form. A large opening that is opened and closed separately from the specific winning opening 65a is provided in the game area, and when the LEDs corresponding to a big win light up in the first symbol display devices 37A and 37B, the specific winning opening 65a is opened for a predetermined time. During the opening of the specific winning opening 65a, when a ball wins into the specific winning opening 65a, a large opening provided separately from the specific winning opening 65a may be formed as a special game state by being opened for a predetermined time and a predetermined number of times. Also, the specific winning opening 65a is not limited to one, and one or a plurality of two or more (for example, three) may be arranged, and the arrangement position is not limited to the right side of the first winning opening 64. For example, it may be on the lower right side of the first winning opening 64, the lower left side of the first winning opening 64, the left or right side, or above the variable display device unit 80.

[0061] At the lower right corner on the lower side of the game board 13, an attachment space K1 for attaching a certificate, an identification label, etc. is provided, and the certificate etc. attached to the attachment space K1 can be visually recognized through the small window 35 (see FIG. 1) of the front frame 14.

[0062] The game board 13 is provided with an out port 71. Balls flowing down in the game area that have not won into any of the winning openings 63, 64, 65a, 640 are guided through the out port 71 to a ball discharge path (not shown). The out ports 71 are arranged in a pair on the left and right of the second winning opening 640.

[0063] The game board 13 is provided with a large number of nails for appropriately dispersing and adjusting the falling direction of the balls, etc., and various members (effect devices) such as a windmill are arranged.

[0064] As shown in FIG. 3, on the back side of the pachinko machine 10, there are mainly provided control board units 90, 91 and a back pack unit 94. The control board unit 90 is unitized by mounting a main board (main control device 110), an audio lamp control board (audio lamp control device 113), and a display control board (display control device 114). The control board unit 91 is unitized by mounting a payout control board (payout control device 111), a firing control board (firing control device 112), a power supply board (power supply device 115), and a card unit connection board 116.

[0065] The back pack unit 94 is unitized by a back pack 92 forming a protective cover portion and a payout unit 93. Also, each control board is mounted with an MPU as a one-chip microcomputer in charge of each control, a port for communicating with various devices, a random number generator used in various lotteries, a clock pulse generation circuit used when performing time counting or synchronization, etc., as required.

[0066] Note that the main control device 110, the audio lamp control device 113, the display control device 114, the payout control device 111, the firing control device 112, the power supply device 115, and the card unit connection board 116 are respectively housed in board boxes 100 to 104. The board boxes 100 to 104 include a box base and a box cover covering the opening of the box base, and the box base and the box cover are connected to each other to house each control device and each board.

[0067] Further, the substrate box 100 (main control device 110) and the substrate box 102 (payout control device 111 and emission control device 112) are connected in a non-openable manner (connected by a caulking structure) by a sealing unit (not shown) between the box base and the box cover. Further, a sealing tape (not shown) is attached across the connection portion between the box base and the box cover. This sealing tape is made of a brittle material, and if an attempt is made to peel off the sealing tape to open the substrate boxes 100 and 102, or if an attempt is made to forcibly open the substrate boxes 100 and 102, it will be cut between the box base side and the box cover side. Therefore, by checking the sealing unit or the sealing tape, it is possible to determine whether the substrate boxes 100 and 102 have been opened.

[0068] The payout unit 93 includes a tank 130 that is located at the uppermost part of the back pack unit 94 and opens upward, a tank rail 131 that is connected below the tank 130 and gently slopes downward toward the downstream side, a case rail 132 that is connected vertically on the downstream side of the tank rail 131, and a payout device 133 that is provided at the lowermost downstream part of the case rail 132 and pays out balls by a predetermined electrical configuration of a payout motor 216 (see FIG. 4). The tank 130 is sequentially replenished with balls supplied from the island equipment in the game hall, and the payout device 133 appropriately pays out the required number of balls. A vibrator 134 for adding vibration to the tank rail 131 is attached to the tank rail 131.

[0069] Further, a state return switch 120 is provided in the payout control device 111, an operation knob 121 of a variable resistor is provided in the emission control device 112, and a RAM erase switch 122 is provided in the power supply device 115. The state return switch 120 is operated to eliminate a ball jam (return to the normal state) when a payout error occurs, such as a ball jam in the payout motor 216 (see FIG. 4) section. The operation knob 121 is operated to adjust the emission force of the emission solenoid. The RAM erase switch 122 is operated when the power is turned on when it is desired to return the pachinko machine 10 to the initial state.

[0070] Next, referring to FIG. 4, the electrical configuration of the pachinko machine 10 will be described. FIG. 4 is a block diagram showing the electrical configuration of the pachinko machine 10.

[0071] The main control device 110 is equipped with an MPU 201 as a one-chip microcomputer which is an arithmetic device. The MPU 201 has a ROM 202 that stores various control programs and fixed-value data executed by the MPU 201, a RAM 203 which is a memory for temporarily storing various data and the like when executing the control programs stored in the ROM 202, and in addition, various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are built in. In the main control device 110, the MPU 201 executes the main processes of the pachinko machine 10 such as jackpot lottery, setting of the displays in the first symbol display devices 37A, 37B and the third symbol display device 81, and lottery of the display result in the second symbol display device.

[0072] Note that, in order to instruct operations to sub-control devices such as the payout control device 111 and the voice lamp control device 113, various commands are transmitted from the main control device 110 to the sub-control devices by the data transmission / reception circuit, but such commands are transmitted only in one direction from the main control device 110 to the sub-control devices.

[0073] The RAM 203 has, in addition to various areas, counters, and flags, a stack area that stores the contents of the internal registers of the MPU 201 and the return destination addresses of the control programs executed by the MPU 201, and a work area (working area) that stores various flags, counters, values of I / O, etc. Note that the RAM 203 is configured to be able to hold (backup) data by receiving a backup voltage from the power supply device 115 even after the power of the pachinko machine 10 is cut off, and all the data stored in the RAM 203 is backed up.

[0074] When the power supply is cut off due to a power failure or the like, the values of the stack pointer and each register at the time of power cut-off (including the occurrence of a power failure; the same applies hereinafter) are stored in the RAM 203. On the other hand, when the power is turned on (including the power-on due to the restoration of power from a power failure; the same applies hereinafter), based on the information stored in the RAM 203, the state of the pachinko machine 10 is restored to the state before the power cut-off. Writing to the RAM 203 is executed at the time of power cut-off by the main process (not shown), and the restoration of each value written to the RAM 203 is executed in the startup process (not shown) at the time of power-on. Note that the NMI terminal (non-maskable interrupt terminal) of the MPU 201 is configured such that a power failure signal SG1 from the power failure monitoring circuit 252 is input at the time of power cut-off due to the occurrence of a power failure or the like. When the power failure signal SG1 is input to the MPU 201, the NMI interrupt process (not shown) as the power failure time process is immediately executed.

[0075] An input / output port 205 is connected to the MPU 201 of the main control device 110 via a bus line 204 composed of an address bus and a data bus. Connected to the input / output port 205 are a payout control device 111, an audio lamp control device 113, first symbol display devices 37A and 37B, a second symbol display device, a second symbol hold lamp, a solenoid 209 including a solenoid for driving the opening / closing plate of the specific winning port 65a in the front-rear direction and a solenoid for driving an electric accessory 640a, etc. The MPU 201 transmits various commands and control signals to these via the input / output port 205.

[0076] Also, connected to the input / output port 205 are various switches 208 including a switch group (not shown) and a sensor group including a slide position detection sensor S and a rotation position detection sensor R not shown, and a RAM erase switch circuit 253 provided in the power supply device 115, which will be described later. The MPU 201 executes various processes based on the signals output from the various switches 208 and the RAM erase signal SG2 output from the RAM erase switch circuit 253.

[0077] The payout control device 111 drives the payout motor 216 to perform payout control of prize balls and lent balls. The MPU 211, which is an arithmetic unit, has a ROM 212 that stores control programs, fixed-value data, etc. executed by the MPU 211, and a RAM 213 used as a work memory, etc.

[0078] Similar to the RAM 203 of the main control device 110, the RAM 213 of the payout control device 111 has a stack area where the contents of the internal registers of the MPU 211 and the return destination addresses of the control programs executed by the MPU 211 are stored, and a work area (working area) where various flags, counters, values of I / O, etc. are stored. The RAM 213 is configured to be able to hold (backup) data by receiving a backup voltage from the power supply device 115 even after the power of the pachinko machine 10 is turned off, and all the data stored in the RAM 213 is backed up. Similar to the MPU 201 of the main control device 110, the NMI terminal of the MPU 211 is also configured such that a power failure signal SG1 is input from the power failure monitoring circuit 252 when a power failure or the like occurs and the power supply is cut off. When the power failure signal SG1 is input to the MPU 211, an NMI interrupt process (not shown) as a power failure-time process is immediately executed.

[0079] An input / output port 215 is connected to the MPU 211 of the payout control device 111 via a bus line 214 composed of an address bus and a data bus. The main control device 110, the payout motor 216, the launch control device 112, etc. are respectively connected to the input / output port 215. Also, although not shown, a prize ball detection switch for detecting the paid-out prize balls is connected to the payout control device 111. The prize ball detection switch is connected to the payout control device 111 but not to the main control device 110.

[0080] When the main control device 110 gives an instruction to launch the ball, the launch control device 112 controls the ball launch unit 112a so that the launch strength of the ball corresponds to the amount of rotation operation of the operation handle 51. The ball launch unit 112a includes a launch solenoid and an electromagnet (not shown), and the launch solenoid and the electromagnet are permitted to be driven when predetermined conditions are met. Specifically, the touch sensor 51a detects that the player is touching the operation handle 51, and when the launch stop switch 51b for stopping the ball launch is off (not operated), the launch solenoid is excited corresponding to the amount of rotation operation (rotation position) of the operation handle 51, and the ball is launched with a strength corresponding to the operation amount of the operation handle 51.

[0081] The voice lamp control device 113 controls the output of voice in the voice output device (such as a speaker not shown) 226, the lighting and extinguishing output in the lamp display device (the electric decoration parts 29 to 33, the display lamp 34, etc.) 227, and the setting of the display mode of the third symbol display device 81 performed by the display control device 114 such as variable effects (variable display) and preview effects. The MPU 221 which is an arithmetic device has a ROM 222 that stores the control program, fixed value data, etc. executed by the MPU 221, and a RAM 223 used as a work memory, etc.

[0082] An input / output port 225 is connected to the MPU 221 of the voice lamp control device 113 via a bus line 224 composed of an address bus and a data bus. The main control device 110, the display control device 114, the voice output device 226, the lamp display device 227, other devices 228, the frame button 22, etc. are respectively connected to the input / output port 225. The other devices 228 include drive motors 441, 541, 731 and the electromagnetic solenoid 2086d.

[0083] The voice lamp control device 113 determines the display mode of the third symbol display device 81 based on various commands (such as a variation pattern command and a stop type command) received from the main control device 110, and notifies the display control device 114 of the determined display mode by commands (such as a display variation pattern command and a display stop type command). Further, the voice lamp control device 113 monitors the input from the frame button 22, and when the frame button 22 is operated by the player, it instructs the display control device 114 to change the stage displayed on the third symbol display device 81 or to change the production content during super reach. When the stage is changed, a background image change command including information about the changed stage is transmitted to the display control device 114 so as to display a background image corresponding to the changed stage on the third symbol display device 81. Here, the background image is an image displayed on the back side of the third symbol, which is the main image to be displayed on the third symbol display device 81. The display control device 114 displays various images on the third symbol display device 81 according to the commands transmitted from this voice lamp control device 113.

[0084] Further, the voice lamp control device 113 receives a command (display command) representing the display content of the third symbol display device 81 from the display control device 114. Based on the display command received from the display control device 114, the voice lamp control device 113 outputs, from the voice output device 226, a voice corresponding to the display content in accordance with the display content of the third symbol display device 81, and also controls the lighting and extinguishing of the lamp display device 227 in correspondence with the display content.

[0085] The display control device 114 is connected to the voice lamp control device 113 and the third symbol display device 81, and controls the display such as the variable effect of the third symbol on the third symbol display device 81 based on the command received from the voice lamp control device 113. Further, the display control device 114 appropriately transmits a display command notifying the display content of the third symbol display device 81 to the voice lamp control device 113. The voice lamp control device 113 can match the display on the third symbol display device 81 with the voice output from the voice output device 226 by outputting voice from the voice output device 226 according to the display content indicated by this display command.

[0086] The power supply device 115 includes a power supply unit 251 for supplying power to each part of the pachinko machine 10, a power failure monitoring circuit 252 for monitoring power interruption due to a power failure or the like, and a RAM erase switch circuit 253 provided with a RAM erase switch 122 (see FIG. 3). The power supply unit 251 is a device that supplies the necessary operating voltage to each of the control devices 110 to 114 and the like through a power supply path (not shown). As an overview, the power supply unit 251 takes in an AC 24-volt voltage supplied from the outside, generates a 12-volt voltage for driving various switches such as various switches 208, solenoids such as solenoid 209, motors, etc., a 5-volt voltage for logic, a backup voltage for RAM backup, etc., and supplies the 12-volt voltage, 5-volt voltage, and backup voltage to the control devices 110 to 114 and the like as necessary voltages.

[0087] The power outage monitoring circuit 252 is a circuit for outputting a power outage signal SG1 to each NMI terminal of the MPU 201 of the main control device 110 and the MPU 211 of the payout control device 111 when the power supply is cut off due to the occurrence of a power outage or the like. The power outage monitoring circuit 252 monitors the voltage of 24 VDC, which is the maximum voltage output from the power supply unit 251. When this voltage becomes less than 22 V, it determines that a power outage (power off, power supply cut off) has occurred, and outputs the power outage signal SG1 to the main control device 110 and the payout control device 111. By the output of the power outage signal SG1, the main control device 110 and the payout control device 111 recognize the occurrence of a power outage and execute NMI interrupt processing. Note that even after the voltage of 24 VDC from the power supply unit 251 becomes less than 22 V, the power supply unit 251 is configured to maintain the output of the 5 V voltage, which is the drive voltage of the control system, at a normal value for a sufficient time to execute the NMI interrupt processing. Therefore, the main control device 110 and the payout control device 111 can normally execute and complete the NMI interrupt processing (not shown).

[0088] The RAM erase switch circuit 253 is a circuit for outputting a RAM erase signal SG2 for clearing backup data to the main control device 110 when the RAM erase switch 122 (see FIG. 3) is pressed. When the main control device 110 inputs the RAM erase signal SG2 at the time of turning on the power of the pachinko machine 10, it clears the backup data and transmits a payout initialization command for clearing the backup data to the payout control device 111 to the payout control device 111.

[0089] Next, the structures of the game board 13 and the operation unit 300 will be described. FIG. 5 is an exploded front perspective view of the game board 13 and the operation unit 300. In the description of FIG. 5, FIG. 2 will be referred to as appropriate.

[0090] As described above, the game board 13 is formed by assembling, on a base plate 60 that has been machined by cutting into a substantially square shape when viewed from the front, a large number of pins (not shown) and windmills (not shown) for guiding balls, as well as rails 61, 62, a general winning opening 63, a first winning opening 64, a second winning opening 640, a through gate 67, a variable winning device 65, a variable display device unit 80, a center frame 86 configured to be fitted into a window portion 60a opened in the base plate 60 from the front side, a left side effect unit 150 arranged at the lower left portion of the center frame 86 and configured to guide balls to the general winning opening 63, a right side effect unit 160 in which the variable winning device 65 is disposed and configured to be fitted into a small window portion 60b opened in the base plate 60 from the front side, a ball flow-down unit (not shown) configured to allow the balls discharged from the game area to flow down, etc., and the peripheral portion thereof is attached to the back side of the inner frame 12 (see FIG. 1).

[0091] The center frame 86, the left side effect unit 150, and the right side effect unit 160 are disposed in through holes formed in the base plate 60 by routing and are fixed to the base plate 60 by tapping screws or the like from the front side of the game board 13.

[0092] The base plate 60 is formed from a wooden plywood in which veneer boards are stacked, and is configured to be able to shield various structures disposed on the back side of the base plate 60 from the front side so that the player cannot visually recognize them, except for open portions such as the window portion 60a and the small window portion 60b.

[0093] As shown in FIG. 5, the left effect unit 150 is a unit formed of a light-transmissive resin material, disposed along the front surface of the base plate 60, and formed in a plate shape having the same width as the inner rail 61. It includes an upper plate portion 151, a lower plate portion 152 extending downward in a plate shape having the same width as the upper plate portion 151 from the left end portion of the upper plate portion 151, and an opposing plate portion 153 formed in a flat plate shape and connected to the rear end portion of the lower plate portion 152 and the rear end portion of the upper plate portion 151, and disposed opposite to the front surface of the base plate 60 in surface contact therewith. The opposing plate portion 153 is mainly provided with a plurality of members fastened and fixed to the front side thereof, and a bottomed semi-cylindrical ball guide member 154 having a bottom on the front side and open upward, and a plurality of protrusion portions 155 formed in a ridge shape extending upward from the upper surface of the lower plate portion 152 at a position below the ball guide member 154.

[0094] At the location where it is disposed opposite to the left effect unit 150, the base plate 60 has no openings except for the opening corresponding to the general winning opening 63. Thus, by utilizing the rigidity of the base plate 60, displacement (deformation) of the opposing plate portion 153 can be prevented, so that regardless of the thickness of the opposing plate portion 153, the flow-down of the balls on the front side of the opposing plate portion 153 can be stabilized.

[0095] In addition, in the present embodiment, the opposing plate portion 153 is disposed on the back side of the path along which the balls that have definitely not won the general winning opening 63 (and the first winning opening 64, the second winning opening 640) flow down, deviating from the ball guide member 154. Thereby, the influence of the opposing plate portion 153 on the flow-down mode of the balls that may enter the winning openings 63, 64, 640 can be reduced.

[0096] In the present embodiment, although the base plate 60 is formed of a wooden plate member, the light irradiated from the irradiation device (for example, the LED member 544 of the rotation unit 500, see FIG. 25) disposed on the back side of the base plate 60 toward the front side can be shown to the player through the opening corresponding to the general winning opening 63. Therefore, it is possible to easily execute a light emission effect in which the surrounding opposing plate portion 153, the upper plate portion 151, etc. do not emit light, and only the ball guide member 154 disposed corresponding to the general winning opening 63 emits light.

[0097] That is, for example, even if the distance between the light-emitting means and the ball guide member 154 is large, the light is constricted by the opening formed in the base plate 60 at the position corresponding to the general winning opening 63. Therefore, a light-emitting effect of making only the ball guide member 154 emit light can be executed. Thus, even without providing dedicated light-emitting means for making the ball guide member 154 emit light, by causing the light irradiated from the LED member 544 (see FIG. 25) of the rotating unit 500 described later to reach the opening formed in the base plate 60 at the position corresponding to the general winning opening 63, a light-emitting effect of making the ball guide member 154 emit light can be executed.

[0098] Thereby, a location (for example, the general winning opening 63) in the game area where a player can gain an advantage when the ball reaches can be easily made prominent. Hereinafter, the details of the left-side effect unit 150 will be described.

[0099] FIG. 6 is a front view of the left-side effect unit 150. As shown in FIG. 6, the protrusion 155 is a portion protruding in a protrusion shape from the upper surface of the lower plate portion 152 over the front-rear direction, and includes a first protrusion 156 disposed on the more upstream side and a second protrusion 157 disposed on the downstream side of the first protrusion 156. Although the shapes (protrusion modes) of the first protrusion 156 and the second protrusion 157 are different, since the underlying concept is the same, the details of the shape of the first protrusion 156 will be described, and for the second protrusion 157, the differences from the first protrusion 156 will be described, and the detailed description will be omitted.

[0100] The first protrusion 156 is configured such that four protrusions of substantially the same shape are arranged in a stepped manner. Since the protrusions are formed in substantially the same shape over the front-rear direction, they can contact the ball regardless of the front-rear position of the ball, and can cause a decelerating effect on the ball.

[0101] Each protrusion is disposed in each range that divides the range vertically below the ball guide member 154 into four equal parts in the left-right direction. That is, since the range vertically below the ball guide member 154 is formed with a left-right width of about 16 [mm], each protrusion is formed with a left-right width of about 4 [mm].

[0102] Each protrusion is configured such that its vertical dimension gradually shortens toward the downstream side. This difference in the vertical length is caused by adjusting the vertical length of the right side portion 156c of the protrusion. Therefore, the upper side portion 156a and the curved portion 156b of the protrusion have the same shape for each protrusion. Details of the upper side portion 156a, the curved portion 156b, and the right side portion 156c will be described later.

[0103] As described above, since the difference in the vertical length of each protrusion is caused by adjusting the vertical length of the right side portion 156c of the protrusion, the first protrusion portion 156 is formed in a stepped shape with equal tread widths while the vertical dimensions of each step decrease downward.

[0104] In particular, the difference between the vertical dimension of the leftmost protrusion and the vertical dimension of the protrusion provided adjacent to its right side is the largest (about 0.35 [mm]), and thereafter, the difference in the vertical dimensions of adjacent protrusions is configured to be about half (about 0.16 - 0.18 [mm]). Details of the vertical dimension for each protrusion will be described later.

[0105] According to this configuration, the deceleration effect on the balls flowing down from the upstream side of the first protrusion portion 156 can be maximized by the first protrusion (the leftmost protrusion), and gradually decreased by the subsequent protrusions. As a result, an appropriate load is applied to the balls at multiple locations, so that the balls can be sufficiently decelerated without locally causing an overload (stress concentration). In addition, compared with the case where the deceleration effect is constant for each protrusion, it is easier to make the deceleration effect correspond to the speed change (speed reduction) of the balls rolling on the first protrusion portion 156. Therefore, it is possible to avoid excessive deceleration and easily prevent the balls from stopping unintentionally.

[0106] In addition, in the second rib portion 157 described later, the difference in the vertical dimensions of adjacent ribs is configured to be all equal (arithmetic progression) (about 0.11 [mm]), and a configuration in which the vertical dimension of the leftmost rib is extremely large is not adopted. The vertical dimensions of each rib will be described later. This is for the purpose of reducing the inclination of the lower plate portion 152 with respect to the horizontal to such an extent that it is unnecessary to greatly decelerate the ball, and for preventing damage to the second rib portion 157. Details will be described later.

[0107] Also, at the position where the vertical difference between adjacent ribs is the smallest, the outer shape of the game ball B1 that contacts the curved portion 156b of the upstream rib and the upper side portion 156a of the downstream rib is illustrated by an imaginary line. As shown in FIG. 6, the center (center of gravity) of the game ball B1 is arranged on the right side of the right end portion of the upper side portion 156a.

[0108] By changing the contacting rib and considering the arrangement of the game balls that contact at the same two points, the vertical dimension of the upstream rib becomes larger as the contacting rib is the upstream rib. Therefore, the game ball will be arranged more to the right. Naturally, the center (center of gravity) of the game ball B1 is arranged on the right side of the right end portion of the upper side portion 156a.

[0109] Therefore, when the game ball B1 is arranged in a state of being sandwiched between adjacent ribs, the weight of the game ball will be directed in the direction of rolling downstream over a plurality of ribs, so that it is possible to avoid the game ball from stopping in a state of being sandwiched between adjacent ribs.

[0110] Details of the configuration of each rib provided in the first rib portion 156 will be described. Each rib includes an upper side portion 156a that extends with a downward inclination with respect to the horizontal direction from the left end portion, a curved portion 156b that is continuously formed from the right end portion of the upper side portion 156a, and a right side portion 156c that extends downward along the vertical direction from the right lower end portion of the curved portion 156b.

[0111] Since the upper side portion 156a is configured as a flat portion that slopes downward in the horizontal direction in a front view and extends flatly in the front - rear direction, it is easy to prevent the ball rolling on the upper surface from stopping unintentionally. The length of the upper side portion 156a in the front view is 3.15 [mm], the inclination angle of the upper side portion 156a with respect to the horizontal direction is about 7 degrees, and the angle with respect to the lower plate portion 152 is about 35 degrees.

[0112] The curved portion 156b is a curved surface configured in a curved shape with a radius of about 1 [mm] in a front view and has a role of assisting the rolling of the ball. That is, compared with the case where the curved portion 156b is configured as a corner portion, the contact between the ball and the protrusion can be continued, and it is easy to maintain the rolling state, so the effect of decelerating the ball can be maintained.

[0113] The lower side portion 156c is designed to have lengths of about 1.42 [mm], about 1.58 [mm], about 1.76 [mm], and about 2.11 [mm] in order from the downstream side. Thereby, the vertical dimensions of each protrusion are designed to be about 2.80 [mm], about 2.96 [mm], about 3.14 [mm], and about 3.49 [mm] in order from the downstream side.

[0114] Since the lower side portion 156c extends in the vertical direction in a front view and is configured as a flat portion that extends flatly in the front - rear direction, it is possible to prevent the ball from being displaced against the inclination of the lower plate portion 152. Thereby, it is easy to make the ball that tends to be displaced in a direction away from the outlet 71 (see FIG. 2) flow down toward the outlet 71.

[0115] The angle of the lower side portion 156c with respect to the horizontal direction is about 90 degrees, and the angle with respect to the lower plate portion 152 is about 56 degrees. In this way, the inclination angle of the protrusion with respect to the lower plate portion 152 is configured such that the angle with respect to the lower plate portion 152 on the downstream side is larger than the angle with respect to the lower plate portion 152 on the upstream side.

[0116] As a result, for the balls reaching the ridges from the upstream side, the change in the inclination angle of the rolling surface is reduced, causing a small decelerating effect that does not cause the balls to stop. On the other hand, for the balls reaching the ridges from the downstream side, by increasing the change in the inclination angle of the rolling surface, the speed of the balls moving towards the upstream side can be effectively reduced, making it easier for the balls to flow towards the downstream side.

[0117] The second ridge portion 157 is configured such that the vertical width of each ridge is shorter than that of the first ridge portion 156. This difference is caused by varying the length of the right side portion 156c of the second ridge portion 157. Therefore, the shape of the upper side portion 156a and the inclination angle with respect to the horizontal direction (i.e., approximately 7 degrees), as well as the shape of the curved portion 156b, etc., are similarly configured for each ridge.

[0118] On the other hand, the lower plate portion 152 is configured in a curved shape with the center of the radius of curvature located on the upper right side. Since the inclination angle (with respect to the horizontal direction) near the second ridge portion 157 is smaller compared to the inclination angle (with respect to the horizontal direction) near the first ridge portion 156, the angle between each ridge of the second ridge portion 157 and the lower plate portion 152 is different from that described above for the first ridge portion 156.

[0119] That is, the length of the upper side portion 156a of the second ridge portion 157 in a front view is 3.15 [mm], the angle of the upper side portion 156a with respect to the lower plate portion 152 is approximately 19 degrees, and the angle of the right side portion 156c with respect to the lower plate portion 152 is approximately 70 degrees. In this way, compared to the numerical values described above for the first ridge portion 156, the inclination angle of the ridge with respect to the lower plate portion 152 is configured such that the angle with respect to the lower plate portion 152 on the downstream side is larger than the angle with respect to the lower plate portion 152 on the upstream side.

[0120] As a result, compared to the above description for the first ridge portion 156, for the balls reaching the ridges from the upstream side, the change in the inclination angle of the rolling surface is reduced, causing a small decelerating effect that does not cause the balls to stop. On the other hand, for the balls reaching the ridges from the downstream side, by increasing the change in the inclination angle of the rolling surface, the speed of the balls moving towards the upstream side can be effectively reduced, making it easier for the balls to flow towards the downstream side.

[0121] The lower side portion 156c of the second rib portion 157 is designed with lengths of approximately 0.16 [mm], approximately 0.27 [mm], approximately 0.38 [mm], and approximately 0.49 [mm] in order from the downstream side. As a result, the vertical dimensions of each rib are designed to be approximately 1.54 [mm], approximately 1.65 [mm], approximately 1.76 [mm], and approximately 1.87 [mm] in order from the downstream side.

[0122] Each rib of the second rib portion 157, in addition to the vertical dimensions of each stage being shorter compared to each rib of the first rib portion 156, is configured such that the differences in the vertical dimensions between adjacent ribs are all equal (an arithmetic difference (approximately 0.11 [mm])). That is, since a configuration where the vertical dimension of the leftmost rib is dramatically large is not adopted, the deceleration rate of the ball rolling on the upper surface can be made uniform, and the durability of the second rib portion can be improved by taking measures against the vulnerability of the left end portion.

[0123] The left side effect unit 150 includes a diffusion portion 158 in which a diffusion shape capable of diffusing light is formed on the front side end surfaces of the upper plate portion 151 and the lower plate portion 152. The diffusion portion 158 can show linear light to the player by diffusing the light that reaches the left side effect unit 150 from the front side through the glass unit 16 (see FIG. 1) or the light that reaches from above, below, left, right, or the back side, and the effect can be improved.

[0124] Since the diffusion portion 158 is also formed on the front side end surfaces of the first rib portion 156 and the second rib portion 157, the diffusion portion 158 can be made partially wide. As a result, the width of the light visible in the first rib portion 156 and the second rib portion 157 can be made larger compared to the width of the light visible in the surrounding area (the portion where neither the first rib portion 156 nor the second rib portion 157 is formed).

[0125] Also, the maximum width of the light visible in the diffusion part 158 on the front side of the first ridge part 156 can be made larger than the maximum width of the light visible in the diffusion part 158 on the front side of the second ridge part 157. Specifically, corresponding to the vertical dimensions of each of the above-described ridges, the width of the light visible in the diffusion part 158 can be changed stepwise. Among the ridges in the first ridge part 156, the ridge with the minimum vertical dimension has a larger vertical dimension than the ridge with the maximum vertical dimension among the ridges in the second ridge part 157. Therefore, the width of the light visible in the diffusion part 158 on the front side of the first ridge part 156 can be made larger than the width of the light visible in the diffusion part 158 on the front side of the second ridge part 157.

[0126] Thereby, the degree of attention of the player looking at the left side effect unit 150 can be made different for each range. That is, the degree of attention of the second ridge part 157 is higher than the degree of attention of the part that is neither the first ridge part 156 nor the second ridge part 157, and the degree of attention of the first ridge part 156 can be made higher than the degree of attention of the second ridge part 157.

[0127] Above the first ridge part 156 and the second ridge part 157 where these degrees of attention are increased, a ball guide member 154 arranged corresponding to the general winning opening 63 is provided. Since the basic gaming posture of the player is a posture of looking down at the general winning opening 63 and the ball guide member 154 arranged on the front side thereof, it is highly possible that the first ridge part 156 and the second ridge part 157 arranged below the ball guide member 154 enter the field of vision.

[0128] And by increasing the degree of attention of the first ridge part 156 and the second ridge part 157 (by irradiating light), the player can easily grasp the left and right positions of the general winning opening 63. Thereby, it is possible to easily draw the player's attention to the general winning opening 63 and the ball guide member 154 arranged on the front side thereof.

[0129] That is, according to the present embodiment, without directly lighting or spectacularly decorating the general winning opening 63 or the ball guide member 154, by increasing the degree of attention of the first ridge portion 156 and the second ridge portion 157, the attention-grabbing power (making it prominent) of the general winning opening 63 and the ball guide member 154 can be improved.

[0130] In addition, the width of the light visible at the diffusion portion 158 is configured to change depending on the vertical dimension of each ridge. However, since the vertical dimension of the leftmost ridge of the first ridge portion 156 is significantly large, it is possible to achieve an effect of strongly attracting the player's line of sight. Thereby, the attention-grabbing power of the leftmost ridge of the first ridge portion 156 as the most upstream position where the ball flowing down from the upstream side of the upper plate portion 151 lands can be improved.

[0131] In addition, since the width of the light visible at the diffusion portion 158 is configured to change depending on the vertical dimension of each ridge, the width of the light gradually decreases as it goes toward the downstream side (right side). Thereby, since the light that gradually becomes thinner toward the downstream of the game area can be visually recognized through the diffusion portion 158, it is possible to show the trajectory of the ball by the light, or to form a sharp appearance by decorating the outer edge of the game area with lights of different thicknesses (tapered lights), and thus the effect as a light emission effect can be achieved.

[0132] In FIG. 6, as main examples of the ball flow-down paths, the flow-down paths L1 and L2 are illustrated. The flow-down path L1 is a path through which the ball that has reached the upper plate portion 151 falls from the right end portion of the upper plate portion 151, and the ball flowing down through the flow-down path L1 reaches (lands) on the upper surface of the lower plate portion 152 on the upstream side of the first ridge portion 156.

[0133] The flow-down path L2 is a path through which the ball that has flowed rightward while flowing over a nail (not shown) without reaching the upper plate portion 151 passes when flowing down between the pair of ball guide members 154, and the ball flowing down through the flow-down path L2 reaches (lands) on the upper surface of the lower plate portion 152 on the upstream side of the second ridge portion 157.

[0134] Thus, since the first rib portion 156 and the second rib portion 157 are formed in a range different from the range where the balls flowing down through the ball flow-down paths L1 and L2 reach (land on) the lower plate portion 152, it is possible to avoid the impact at the time of the balls' reaching (landing) being applied to the first rib portion 156 and the second rib portion 157.

[0135] In addition, since the first rib portion 156 and the second rib portion 157 are disposed on the downstream side of the reaching (landing) range of the balls, it is possible to decelerate the balls flowing down through the flow-down paths L1 and L2 before they reach the out-port 71. Thereby, it is possible to easily avoid the portion disposed in the path up to the out-port 71 from being damaged by the load (impact) received from the balls.

[0136] When the ball rolling on the lower plate portion 152 starts to contact the first rib portion 156, the repulsive force applied from the first rib portion 156 to the ball faces the right side without approaching the side where the ball reaches, so that the stop of the ball can be avoided. On the other hand, since the direction of the repulsive force depends on the shape of each rib, it varies greatly depending on the side where the ball reaches.

[0137] For example, when the ball reaches (starts to contact) the first rib portion 156 from the upstream side (left side), the direction of the repulsive force occurs at a right angle to the upper side portion 156a, so that it becomes a substantially upward load F1. On the other hand, when the ball reaches (starts to contact) the first rib portion 156 from the downstream side (right side), the direction of the repulsive force does not contact the right side portion 156c and occurs at a right angle to the curved portion 156b, but becomes a substantially rightward load F2.

[0138] Therefore, for the balls reaching from the upstream side, it is possible to gently cause a change in speed in the left-right direction, and for the balls reaching from the downstream side, it is possible to violently cause a change in speed in the left-right direction (reverse the speed).

[0139] The ball may bounce back to the left by colliding with other balls arranged near the outlet 71 or with a component member arranged on the front side of the outlet 71. Although it is less likely for this ball to reach the first ridge portion 156, it is more likely to reach the second ridge portion 157 which is arranged lower and closer to the outlet 71.

[0140] Therefore, although the second ridge portion 157 is provided at a position deviated from the landing position of the balls flowing down through the flow-down paths L1 and L2 by forming it on the lower side of the ball guide member 154, there is a possibility that the ball rebounded due to the above circumstances may collide with the second ridge portion 157. So, if the second ridge portion 157 is fragile, there is a possibility that the second ridge portion 157 may be damaged by the impact of the ball collision.

[0141] On the other hand, in the present embodiment, each ridge provided in the second ridge portion 157 is configured such that the difference in the vertical dimensions between adjacent ridges is the same (is an arithmetic progression), and a configuration in which the vertical dimension of the leftmost ridge is extremely large is not adopted. Thereby, compared with the case where a specific ridge is configured to be overly sharp, the second ridge portion 157 can be configured to be less likely to be damaged.

[0142] In addition, since each ridge is protrudingly formed in a strip shape from the upper surface of the lower plate portion 152 in the front-rear direction, the second ridge portion 157 can be configured to be less likely to be damaged compared to the case where it is protrudingly provided in a corner (pointed) shape.

[0143] FIG. 7(a) is a cross-sectional view of the left effect unit 150 taken along the VIIa-VIIa line in FIG. 6, and FIG. 7(b) is a cross-sectional view of the left effect unit 150 taken along the VIIb-VIIb line in FIG. 6.

[0144] As shown in FIGS. 7(a) and 7(b), the thicknesses of the first ridge portion 156 and the second ridge portion 157 are configured to be the same, and concave grooves having a depth corresponding to the opposite side of the ridge are formed. By making the thicknesses the same, the molding accuracy of the left effect unit 150 formed from a resin material can be maintained high.

[0145] As described above, while the thicknesses of the first rib portion 156 and the second rib portion 157 are formed equally, the diffusion portion 158 is formed to project downward from the first rib portion 156 and the second rib portion 157 so as to cover the concave groove from the front side. That is, the diffusion portion 158 is formed with a width dimension greater than or equal to the thickness of the first rib portion 156 and the second rib portion 157.

[0146] As described above, since the vertical dimension of each rib of the first rib portion 156 is longer than that of the second rib portion 157, the concave groove is also deeper in the first rib portion 156 than in the second rib portion 157. Correspondingly, the width dimension (maximum value) of the diffusion portion 158 is longer for the diffusion portion 158 disposed on the front side of the first rib portion 156 than for the diffusion portion 158 disposed on the front side of the second rib portion 157.

[0147] Thereby, regardless of the thickness of the first rib portion 156 and the second rib portion 157, the width of the diffusion portion 158 can be widened, so that the width of the light visually recognized through the diffusion portion 158 can be widened.

[0148] Thereby, the attention to the diffusion portion 158 and the first rib portion 156 and the second rib portion 157 connected to the upper end portion of the diffusion portion 158 can be improved, and the presence or absence of a ball entering the general winning opening 63 can be grasped by looking in the direction facing the first rib portion 156 and the second rib portion 157. This will be described below.

[0149] As shown in FIG. 7(a), the line of sight YE1 of the player playing the game often follows a line (radial line) that goes outward from the game area as it goes toward the back side. Therefore, the line of sight YE1 of the player looking at the rib portion 155 corresponding to the lower edge portion of the game area is a downwardly inclined line of sight as it goes toward the back side.

[0150] The player who turns his / her eyes in the direction of the line of sight YE1 can see not only the rib portion 155 that intersects the line of sight YE1 but also the light reflected by the rib portion 155. That is, the reflected light R1 that enters the rib portion 155 through the opposing plate portion 153 and is reflected along the line of sight YE1 can be seen through the rib portion 155.

[0151] The reflected light R1 travels downward through the spherical guide member 154, enters (reflects off) the opposing plate portion 153, and then enters (reflects off) the protruding strip portion 155. That is, the light source of the reflected light R1 is disposed above the spherical guide member 154, and by the opposing plate portion 153 serving as a reflecting means (e.g., a mirror), the reflected light R1 reaches the protruding strip portion 155.

[0152] In this way, the reflected light R1 is light that passes through the passage of the ball to the general winning opening 63 (see FIG. 5) through the spherical guide member 154. Therefore, when viewing the protruding strip portion 155 with the line of sight YE1, a ball may be reflected on the protruding strip portion 155, or the protruding strip portion 155 may appear dark due to the light being blocked by the ball. As a result, the player can grasp the presence or absence of a ball entering the general winning opening 63 through the change in the reflected light R1. Accordingly, while reducing the player's fatigue, the player can efficiently grasp profitable information. This will be described below.

[0153] Conventionally, in a game in a normal gaming state, the player often moved the line of sight between the general winning opening 63 and the vicinity of the inner rail 61. This is to obtain information useful for the game from the flowing state of the balls in the game area.

[0154] First, when a ball enters the general winning opening 63, prize balls (in this embodiment, 5 to 15 balls) are paid out. Therefore, the higher the frequency of balls entering the general winning opening 63, the better the ball supply of the pachinko machine 10 during the game can be judged. Second, the higher the frequency of balls reaching the vicinity of the inner rail 61, the higher the frequency of balls being discharged from the out port 71 of the pachinko machine 10 during the game can be judged. At first glance, it may seem that the lower the frequency of balls reaching the vicinity of the inner rail 61, the more profitable the pachinko machine 10 is for the player, but this is not always the case.

[0155] These pieces of information are incomplete when grasped individually and need to be grasped comprehensively. For example, just because the frequency of balls reaching the vicinity of the inner rail 61 is low, it is not known whether the pachinko machine 10 is profitable for the player.

[0156] Even in this case, if the frequency of balls entering the general winning opening 63 is excessively high, the frequency of balls entering the first winning opening 64 will be low. Therefore, it is considered that the frequency of jackpot draws in the pachinko machine 10 during the game is low. For this reason, it can be expected that a long time is required to obtain a jackpot. Therefore, for a player with a short playable time, there is a high possibility that the player will not play the game (there is a high possibility that it cannot be said that there is a benefit for the player).

[0157] From this perspective, the player needs to move the line of sight between the general winning opening 63 and the vicinity of the inner rail 61 to obtain information at each location. However, if the number of times the line of sight is moved is large, there arises a problem that the fatigue of the player increases and it easily leads to a decrease in the motivation for the game.

[0158] On the other hand, in the present embodiment, it is configured such that information at a plurality of locations can be obtained without moving the line of sight. That is, without moving the line of sight from the line of sight YE1 looking at the ridge portion 155, it is possible to grasp the frequency of balls reaching the vicinity of the inner rail 61 and the frequency of balls entering the general winning opening 63. Thereby, it is possible to reduce the fatigue of the player and prevent a decrease in the motivation for the game, while efficiently allowing the player to grasp information that is beneficial to the player.

[0159] In addition, since the presence or absence of a ball entering the general winning opening 63 can be grasped if the mode of the reflected light R1 changes, the degree of light reflection through the opposed plate portion 153 is not limited in any way, and various modes are exemplified. For example, a shape with low light reflection efficiency due to being subjected to dimpling may be used, or mirror processing may be performed, or a separate member having a mirror surface (sealing member or mirror-like member) may be disposed to increase the light reflection efficiency.

[0160] Also, the angle between the front surface of the opposed plate portion 153 and the front surface of the base plate 60 is not limited in any way, and various modes are exemplified. For example, they may be parallel, or the front surface of the opposed plate portion 153 may be configured as an inclined surface. Thereby, it is possible to suitably correspond to the position of the light source of the reflected light R1.

[0161] FIG. 8 is a cross-sectional view of the game board 13 taken along line VIII-VIII of FIG. 6. As shown in FIG. 8, the ball that has reached (landed on) the lower plate portion 152 flows downward through the flow path L3 toward the lower part of the game area.

[0162] The ball flowing down through the flow path L3 reaches the front side of the out port 71 while hitting the glass unit 16 (front side) and the base plate 60 (rear side), and then is discharged from the game area through the out port 71.

[0163] When the momentum of the ball is strong, the ball that has jumped out to the right from the lower end of the lower plate portion 152 may collide with the movable device 640a. If the movable device 640a is damaged due to this collision, it becomes difficult to continue the normal game, so it is desirable to avoid the ball from colliding with the movable device 640a.

[0164] Also, a front design member FD1 formed of a light-transmissive resin is disposed on the front side of the movable device 640a, and the movable device 640a is covered with the front design member FD1, so it is difficult to notice whether the movable device 640a is damaged. From this, it is also required to prevent the damage of the movable device 640a in advance, and it is desirable to avoid the ball from colliding with the movable device 640a.

[0165] On the other hand, in the present embodiment, a protrusion 155 is provided in the flow path L3 to decelerate the ball, so that the momentum of the ball is reduced to less than the momentum required for the ball that has jumped out to the right from the lower end of the lower plate portion 152 to reach the movable device 640a. Thereby, the damage of the movable device 640a can be prevented in advance.

[0166] As shown in FIG. 8, the protrusion 155 is disposed at a position included in the left-right width of the ball guiding member 154 in a top view. Specifically, the ball guiding member 154 is configured such that the sum of the left-right width of the passage path of the ball and the left-right width of a pair of fastening portions disposed on the left and right thereof is equal to or greater than the left-right width (about 16 [mm]) of the protrusion 155.

[0167] As a result, the ball guide member 154 can be used as a protective member for the protruding strip portion 155. That is, when the ball drops toward the protruding strip portion 155, the ball guide member 154 will interfere with the dropping path of the ball, so that the dropping path of the ball can be changed, and it can be made easier to avoid (reduce the frequency of) the ball from colliding (landing) with the protruding strip portion 155.

[0168] Therefore, it can be made easier to limit the contact between the ball and the protruding strip portion 155 to the contact with the ball that flows down (rolls) after landing on the lower plate portion 152. Thus, it is possible to prevent the protruding strip portion 155 from cracking or being damaged due to the collision of the ball, and the deceleration effect of the ball by the protruding strip portion 155 can be maintained for a long period of time.

[0169] As described above, in the variable display device unit 80, the center frame 86 is disposed so as to surround the third symbol display device 81 in a front view, and the window portion 60a is formed to open according to the size of the center frame 86. In this embodiment, the shape of the window portion 60a has a feature with respect to the shape of the center frame 86. This will be described with reference to FIG. 9.

[0170] FIG. 9 is a front view of the base plate 60. In FIG. 9, a line showing the shape of the center frame 86 in a state of being assembled to the base plate 60 is schematically illustrated as an imaginary line.

[0171] That is, the center frame 86 is a member formed of a light-transmissive resin material, and includes a flat plate portion 86a that is disposed opposite to the base plate 60 from the front side and has a through hole through which a fastening screw passes, a boundary wall portion 86b that projects in a wall shape on the front side of the flat plate portion 86a and constitutes a boundary portion of the game area, and a diversion plate portion 86c that projects in a plate shape on the front side of the flat plate portion 86a at a substantially intermediate position between the inner rail 61 and the lower left portion of the boundary wall portion 86b and is provided parallel to the adjacent boundary wall portion 86b (see FIG. 5). In FIG. 9, the outer edge shape and inner edge shape of the flat plate portion 86a, the shape of the boundary wall portion 86b, and the shape of the diversion plate portion 86c are illustrated as imaginary lines.

[0172] As shown in FIG. 9, in the range where the boundary wall portion 86b constitutes the rolling surface (flowing surface) of the ball (the range where the normal line passing through the outer surface of the boundary wall portion faces upward), the window portion 60a of the base plate 60 is provided in a range that extends to the outside of the boundary wall portion 86b in a front view. Therefore, light can pass through the window portion 60a not only inside the boundary wall portion 86b (on the center side of the window portion 60a) but also outside the boundary wall portion 86b.

[0173] As a result, the light that has passed through the window portion 60a can be applied to the ball that rolls on the upper surface of the boundary wall portion 86b, and a light emission effect that lights up the ball can be executed. Here, the upper surface of the boundary wall portion 86b is a portion that is likely to be a blind spot for a player who plays the game while paying attention to the third symbol display device 81 (see FIG. 2), and it is a portion where the ball is likely to be partially hidden and difficult to see. However, since the mode of the light passing through the window portion 60a changes depending on whether the ball is present or not, the player can easily grasp whether the ball is present or not by checking the mode of the light.

[0174] Also, in the present embodiment, by utilizing this blind spot, the efficiency of the area where the effect is executed is improved, and this will be described with reference to FIG. 10.

[0175] FIG. 10 is a cross-sectional view of the gaming machine 13 along a line corresponding to the X-X line of FIG. 9. In FIG. 10, an example of the arrangement of the eyes of a player when playing the game while viewing the third symbol display device 81 from the front is shown. In the eye arrangement shown in FIG. 10, the third symbol display device 81 can be visually recognized with the line of sight YE2 in the front-rear direction, while the boundary wall portion 86b disposed above the center frame 86 can be visually recognized with the line of sight YE3 in a direction of looking up.

[0176] When viewing the game area with the line of sight YE3, at least a part of the field of view is blocked by the boundary wall portion 86b and the decorative portion disposed inside (lower side) thereof, and the shielded range SE1 blocked by the boundary wall portion 86b and the decorative portion becomes difficult to see (becomes a blind spot). In the present embodiment, at a position overlapping the shielded range SE1 in the front-rear direction, an opening is deliberately formed in the base plate 60 to provide a window portion 60a. In other words, by not treating the shielded range SE1 as a location where a pattern or figure is drawn, an effective use of the blind spot range is achieved. This will be described below.

[0177] Conventionally, when the base plate 60 is made of a wooden member, a decoration method of creating the individuality of each gaming machine by mainly pasting a seal with a pattern or figure drawn (printed) on the rear side range of the game area has been adopted.

[0178] In this case, even if a pattern or figure is drawn in a range that is likely to become a blind spot near the wall-like portion that protrudes toward the game area side, such as the boundary wall portion 86b and the decorative portion, it is difficult for the player to visually recognize it, so it is difficult to enhance the production effect.

[0179] There is also an option not to paste a seal in this range that is likely to become a blind spot, and by reducing the area of the seal in this way, the material cost of the seal can be reduced. However, since the player's line of sight is not always fixed, when the line of sight changes and the portion where the seal is not pasted and the base plate 60 (wooden board member) is exposed is visually recognized, it may give the player an impression of being cheap and may lead to a decrease in the gaming motivation. Therefore, it is hard to say that the option of not pasting a decorative seal in the range that is likely to become a blind spot is preferable, and improvement has been desired.

[0180] Also, when completing a pattern or figure in a range outside the blind spot, it is necessary to draw the pattern or figure in a further narrowed range of the game area, which is already limited in size, and it has been difficult to increase the degree of freedom in decorating the game area.

[0181] In contrast, in the present embodiment, by providing the window portion 60a in the base plate 60 in a range overlapping at least a part of the shielded range SE1, the shielded range SE1 is employed not as a place for drawing figures or patterns but as a passage for light. That is, according to the present embodiment, the transmitted light R2 that is irradiated from the effect means (for example, the supported means 760, see FIG. 37) disposed on the back side of the base plate 60 and travels toward the front side can be configured to pass through the flat plate portion 86a in the shielded range SE1.

[0182] As a result, even when the option of not pasting a seal with a pattern or figure drawn thereon on the shielded range SE1 is selected, the flat plate portion 86a that shines illuminated by the transmitted light R2 can be shown to the player who visually recognizes the shielded area SE1. Therefore, it is possible to reduce the possibility of giving the player an impression of being cheap, and as a result, it is possible to prevent a decrease in the gaming motivation.

[0183] In addition, since the line of sight YE3 and the transmitted light R2 overlap, the player can visually recognize the pattern or figure drawn on the seal pasted on the base plate 60 and the transmitted light R2 in an overlapping manner. At least, the appearance of the gaming area visually recognized by the line of sight YE3 can be changed between the irradiated state and the non-irradiated state of the transmitted light R2, so that the degree of freedom in decorating the gaming area can be improved.

[0184] In this way, in the present embodiment, the shielded range SE1 as a blind spot is effectively utilized, and as a result, the degree of freedom in decorating the game board 13 can be increased, and the effect of the game board 13 can be enhanced.

[0185] In the present embodiment, the boundary wall portion 86b includes a left boundary wall portion 86b1 extending from the upper end portion to the lower left side and a right boundary wall portion 86b2 extending from the upper end portion to the lower right side. In each case, the region through which light visible within the gaming area passes is linearly configured, but the widths are different.

[0186] That is, on the right boundary wall portion 86b2 side, the distance from the outer rail 62 and the outer edge member 73 is narrow, and the path of the ball is substantially constant, so the width for passing light is also configured to be narrow (about 5 [mm] or less). On the other hand, on the left boundary wall portion 86b1 side, the locations where the ball lands vary in terms of launch intensity, and whether the ball collides with a nail (not shown) before landing also causes the bouncing behavior after landing to change, so the path of the ball is unlikely to be constant (variations occur). Therefore, in the present embodiment, for the purpose of accommodating variations in the flow path of the ball, the width for passing light is configured to be wide (up to about 12 [mm]).

[0187] In particular, around the flow dividing plate portion 86c, the window portion 60a is provided in a manner that extends to a position overlapping both the left and right ranges of the flow dividing plate portion 86c, and the width for passing light is set to be equal to or greater than the diameter of the ball (about 11 [mm] or more). As a result, transmitted light R2 can be applied to the balls flowing down on either the left or right side of the flow dividing plate portion 86c.

[0188] Thus, according to the present embodiment, since the shape of the window portion 60a is designed so that transmitted light R2 can be easily applied to the balls rolling on the boundary wall portion 86b, transmitted light R2 can be efficiently applied to the balls flowing down in the game area. Therefore, even when the ball flows down to a location that is likely to be blocked by the boundary wall portion 86b and become a blind spot, the appearance of the transmitted light R2 can be changed according to the presence or absence of the ball, enabling the player to easily grasp the presence or absence of the ball.

[0189] An example of the irradiation mode of the transmitted light R2 will be described. For example, when notifying the player to play a left-handed shot, light may be irradiated to the left boundary wall portion 86b1 side, and when notifying the player to play a right-handed shot, light may be irradiated to the right boundary wall portion 86b2 side for control. In this case, by looking at the boundary wall portion 86b, the player can easily grasp whether to launch the ball with a left-handed shot or a right-handed shot.

[0190] Also, the irradiation mode of the transmitted light R2 is not limited in any way. For example, an irradiation mode of continuous lighting may be used, or an irradiation mode of repeating lighting and extinguishing (flashing) may be used.

[0191] Also, the irradiation mode for lighting up the periphery of the flow dividing plate portion 86c is not limited in any way. For example, an irradiation mode in which both the left and right sides of the flow dividing plate portion 86c are lit up may be used, or an irradiation mode in which only one of the left or right sides of the flow dividing plate portion 86c is lit up may be used.

[0192] For example, when most of the balls flow to the left side of the flow dividing plate portion 86c and the game area is configured such that the ball emission intensity is limited only when it drops below a specific standard, in a control mode where the transmitted light R2 is irradiated so as to light up only the left side of the flow dividing plate portion 86c, the player can easily grasp whether the ball emission intensity has dropped below a specific standard by checking the brightness of this transmitted light R2.

[0193] That is, when the ball passes through the left side of the flow dividing plate portion 86c, the transmitted light R2 is blocked by the ball and the left side of the flow dividing plate portion 86c is visually recognized as being dark. Therefore, the brightness of the transmitted light R2 can be associated with the fact that the ball emission intensity has dropped below a specific standard. As a result, compared to the case where the player grasps the ball emission intensity by checking the landing position of the ball, the stress felt by the player when adjusting (maintaining) the ball emission intensity can be reduced.

[0194] Thus, according to the present embodiment, by configuring the areas that are shielded by the boundary wall portion 86b and the flow dividing plate portion 86c and become blind spots as paths for the transmitted light R2 that travels from the back side to the front side, the degree of freedom of the light effects in the game area can be improved. Note that the range in which the blind spots are formed is not limited to above the boundary wall portion 86b or to the left of the flow dividing plate portion 86c, and various modes are exemplified.

[0195] For example, it may be in the range below a pair of plate-like portions extending toward the lower left and right sides of the first winning port 64, or in the range outside the inner rail 61 or the outer rail 62 (on the opposite side of the game area), or in the range below the upper plate portion 151 (see FIG. 5) of the left side effect unit 150, or in the range below the ball guide member 154 (see FIG. 5) that guides the ball to the general winning port 63 arranged on the left side of the game area, or in the range below the plate-like portion extending toward the lower right side of the general winning port 63 (see FIG. 2) arranged on the right side of the game area, or in the range outside the center frame 86 (on the opposite side of the third symbol display device 81 in a front view), or in the peripheral range of other plate-like portions protruding toward the front side of the base plate 60.

[0196] Returning to FIG. 5 for explanation. The right side effect unit 160 is a unit provided with the variable winning device 65, and is fitted into the small window portion 60b of the base plate 60 from the front side. The ball that has entered the specific winning port 65a (see FIG. 2) of the variable winning device 65 flows down through the flow-down path FL1 (see FIG. 11) formed on the back side of the right side effect unit 160 and is guided to a ball discharge path (not shown).

[0197] FIG. 11 is a rear view of the right side effect unit 160. The right side effect unit 160 includes a base member 161 that has an opening portion opened toward the back side and constitutes the front side portion of the flow-down path FL1, a first flow path member 162 and a second flow path member 163 that constitute the back side portion of the flow-down path FL1, an adjustment member 165 that is arranged on the front side of the second flow path member 163 and is configured to be fitted with the second flow path member 163, and a plurality of decorative substrates 168 on which light emitting means such as LEDs that emit light toward the front side are arranged.

[0198] The game ball that has passed through the specific winning port 65a and entered the flow-down path FL1 flows down the front side of the first flow path member 162, and then flows down the front side of the second flow path member 163. That is, the first flow path member 162 constitutes the flow-down path FL1 on the upstream side of the second flow path member 163.

[0199] The decorative substrate 168 includes a first decorative substrate 168a disposed on the back side of the opening / closing plate of the variable prize device 65, a second decorative substrate 168b disposed on the back side of the area outside the ball flow path, and a third decorative substrate 168c fastened and fixed to the back side of the second flow path member 163 and disposed on the back side of the flow-down path FL1.

[0200] In addition, in FIG. 11, the outer shapes of the respective LEDs (light emitting means) are shown by hidden lines inside the decorative substrate 168. As shown in FIG. 11, the respective LEDs are not arranged in a pattern where they are sparse or dense depending on the location, but are arranged in a substantially uniform dispersion on the decorative substrate 168.

[0201] The first decorative substrate 168a can execute a light emission effect that lights up the opening / closing plate of the variable prize device 65 and the opening portion through which the game ball can enter in the open state of the opening / closing plate. The second decorative substrate 168b can execute a light emission effect that lights up the front design portion of the right effect unit 160 regardless of the game ball flowing down inside the right effect unit 160.

[0202] The third decorative substrate 168c can execute a light emission effect in which the way of lighting changes in relation to the game ball flowing down the flow-down path FL1. That is, when a game ball is disposed on the second flow path member 163, the player can visually recognize the shadow generated by the light emitted from the third decorative substrate 168c being blocked by the game ball. On the other hand, when no game ball is disposed on the second flow path member 163, the shadow of the game ball can be made invisible.

[0203] The light irradiated from the third decorative substrate 168c passes through the second flow path member 163, the adjustment member 165, and the base member 161 in sequence, and then passes to the front side of the right effect unit 160 and is visually recognized by the player. The larger the number of members through which the light passes, the more easily the light amount of the visually recognized light attenuates.

[0204] On the other hand, in this embodiment, since the adjustment member 165 is disposed on the front side of the lower end portion of the second flow path member 163 (the end portion of the downward flow path FL1 within the range visible to the player), it is possible to limit the portion where the light quantity is likely to attenuate to the vicinity of the end portion of the downward flow path FL1. As a result, compared with the case where the light quantity attenuates at an intermediate position in the downward flow path FL1, the effect of the illumination by the light irradiated from the third decorative substrate 168c can be improved.

[0205] Furthermore, since the balls passing through the downward flow path FL1 are visible even in a front view, the player usually looks down at the right-side effect unit 160 disposed in the lower right portion of the game area. Therefore, the possibility that the straight line connecting the player's line of sight and the third decorative substrate 168c (a straight line that slopes obliquely downward as it approaches the pachinko machine 10 from the player's eyes) intersects the line segment connecting the adjustment member 165 and the third decorative substrate 168c (a straight line that extends in the front-rear direction passing through a part of the adjustment member 165) is low.

[0206] This is the effect of disposing the adjustment member 165 at a position away from the player's eyes (near the lower end position of the window portion 14c (see FIG. 2)). As a result, it is possible to reduce the possibility that the player pays attention to the range where the light quantity is attenuated by the adjustment member 165. Therefore, it is possible to avoid the effect of the illumination of the light visible to the player by the light irradiated from the third decorative substrate 168c from being reduced by the adjustment member 165.

[0207] FIG. 12 is an exploded rear view of the right-side effect unit 160, FIG. 13 is an exploded front perspective view of the right-side effect unit 160, and FIG. 14 is an exploded rear perspective view of the right-side effect unit 160. In FIG. 12, for easy understanding, the first flow path member 162 is assembled to the base member 161, and the second flow path member 163 and the adjustment member 165 are shown in a disassembled state.

[0208] The base member 161 includes a semi-formed portion 161a on the front side surface of the flow-down path FL1 that is open toward the back side, a pair of columnar fastening portions 161b that project columnarly toward the back side and into which a fastening screw inserted through the first flow path member 162 is screwed into a female screw formed at the tip, a specific columnar fastening portion 161c that has a longer protruding length than the columnar fastening portion 161b and projects columnarly toward the back side and into which a fastening screw inserted through the second flow path member 163 is screwed into a female screw formed at the tip, a plurality of protruding ridges 161d that project in a thin plate shape in the radially outward direction on the base end side of the specific columnar fastening portion 161c, and a recessed portion 161e that is recessed from the back side to the front side of the base member 161 within the range including the specific columnar fastening portion 161c.

[0209] The plurality of protruding ridges 161d are formed at angular positions corresponding to the notch portion 165e and the outer diameter recessed portion 165g of the adjustment member 165. By aligning the notch portion 165e with the protruding ridges 161d, it is possible to easily align the posture when assembling the adjustment member 165.

[0210] The recessed portion 161e is recessed in a shape corresponding to the plate-shaped portion 165a of the adjustment member 165 (a shape larger by the adjustment width) and functions as a recess for arranging the plate-shaped portion 165a. In the assembled state where the plate-shaped portion 165a is disposed in the recessed portion 161e (see FIG. 11), the back surface of the plate-shaped portion 165a is disposed on the surface where the back surface of the base member 161 is disposed (in other words, the back surface of the base member 161 and the back surface of the plate-shaped portion 165a are flush).

[0211] That is, although the adjustment member 165 is a member disposed on the front side of the flow-down path FL1, the difference in the arrangement within the recessed portion 161e does not affect the shape of the flow-down path FL1. Therefore, as will be described later, even when the adjustment member 165 is positionally adjusted by the adjustment width with respect to the recessed portion 161e, it is possible to prevent the shape of the flow-down path FL1 from changing due to the positional adjustment.

[0212] In other words, regardless of the arrangement of the adjustment member 165, if the base member 161, the first flow path member 162, and the second flow path member 163 are assembled in an arrangement suitable for allowing the balls to flow down, the balls are configured to be able to flow down the flow down path FL1. Therefore, compared with the case where a part of the flow path shape (for example, a half-pipe shape) as seen in the semi-formed portions 161a, 162a, and 163a is also formed in the adjustment member 165, the difficulty of assembling the right-side effect unit 160 can be reduced.

[0213] The first flow path member 162 includes a semi-formed portion 162a in which a side surface on the back side of the flow down path FL1 is formed and which is open toward the front side, a pair of insertion holes 162b through which fastening screws for fastening and fixing to the columnar fastening portion 161b can be inserted, and a columnar fastening portion 162c to which a fastening screw inserted through the second flow path member 163 is screwed into a female screw formed at the tip and protruding cylindrically toward the back side.

[0214] The second flow path member 163 includes a semi-formed portion 163a in which a side surface on the back side of the flow down path FL1 is formed and which is open toward the front side, an insertion hole 163b through which a fastening screw for fastening and fixing to the columnar fastening portion 162b can be inserted, an insertion hole 163c through which a fastening screw for fastening and fixing to the specific columnar fastening portion 161c can be inserted, and a plurality of fitting convex portions 163d protruding in a small-diameter cylindrical shape from the front side end of the semi-formed portion 163a toward the front side.

[0215] The adjusting member 165 is a member formed of a light-transmissive resin material, and includes a plate-shaped portion 165a formed in a plate shape with an outer shape slightly smaller than the outer shape of the recessed portion 161e and a thickness equal to the depth of the recessed portion 161e, a plurality of fitting holes 165b formed in the plate-shaped portion 165a at a position corresponding to the fitting convex portion 163d and having a diameter slightly larger than the diameter of the fitting convex portion 163d, a chamfered portion 165c formed by chamfering at a corner where the upper surface and the back surface of the plate-shaped portion 165a intersect, a dish portion 165d formed on a deep dish with the front side open at the right end portion of the plate-shaped portion 165a, a notch portion 165e formed by tapering and notching from the edge portion of the dish portion 165d toward the bottom of the dish, an adjustment hole 165f formed in the front-rear direction with an inner diameter sufficiently larger than the diameter of the specific columnar fastening portion 161c at the center of the bottom of the dish portion 165d, and a plurality of outer diameter recessed portions 165g recessed in the adjustment hole 165f in the outer diameter direction of the adjustment hole 165f.

[0216] The fitting hole 165b is configured to be capable of fitting with the fitting convex portion 163d of the second flow path member 163 in the assembled state (see FIG. 11). By this fitting, the rigidity of the second flow path member 163 can be enhanced.

[0217] Specifically, the second flow path member 163 is preferably formed with a thin wall not only from the viewpoint of material cost but also for the purpose of making the light irradiated from a light emitting means such as an LED disposed on the front surface of the third decorative substrate 168c easily visible to the player (for the purpose of suppressing light attenuation).

[0218] On the other hand, when the second flow path member 163 is formed with a thin wall, without any countermeasures, the second flow path member 163 may be deformed outward by the load applied from the flowing game balls. In contrast, in the present embodiment, by fitting the fitting convex portion 163d of the second flow path member 163 into the fitting hole 165b, it is possible to generate a resistance against the load acting outward on the flow path. Thereby, deformation of the second flow path member 163 can be prevented.

[0219] The chamfered portion 165c is a processed portion for preventing the corner from colliding with the ball flowing down the flow path FL1. Therefore, it suffices to be formed only at the minimum position (for example, the range between a pair of fitting holes 165b) that faces the ball flowing down the flow path FL1. By forming it in this way, unnecessary processing costs can be reduced.

[0220] When the chamfered portion 165c is formed at the corner facing the ball flowing down the flow path FL1, even when the adjustment member 165 protrudes backward from the recessed portion 161e of the base member 161 due to dimensional errors or the like, the collision location between the ball and the adjustment member 165 can be configured as a surface. Thereby, the possibility of the adjustment member 165 being damaged can be reduced, and the flow resistance of the ball can be reduced.

[0221] Since the dish portion 165d protrudes backward compared to the plate-like portion 165a, it is easy to grasp and functions as a handle when removing the adjustment member 165 during assembly or maintenance. During assembly, since the notch portion 165e is tapered, the notch portion 165e is easily guided by the protrusion 161d, so that the alignment of the adjustment member 165 can be easily performed. Therefore, the assembly operation of inserting the specific columnar fastening portion 161c into the adjustment hole 165f can be easily performed.

[0222] In a state where the specific columnar fastening portion 161c is inserted into the adjustment hole 165f, the posture of the adjustment member 165 can be changed (adjusted) with the clearance dimension between the notch portion 165e and the outer diameter recessed portion 165g and the protrusion 161d as the upper limit. The mode of adjustment will be described later.

[0223] Here, the purpose of configuring the adjustment member 165 as a variable member will be described. In the present embodiment, both the upstream first flow path member 162 and the downstream second flow path member 163 utilize the shape on the back side of the base member 161 to configure the shape on the front side of the flow-down path FL1. Compared with the case where other members for configuring the shape on the front side of the flow-down path FL1 are individually prepared for each of the first flow path member 162 and the second flow path member 163, the number of members constituting the flow-down path FL1 can be reduced. Thereby, the material cost can be reduced.

[0224] On the other hand, in resin molding, variations in dimensions occur, so flow path members of exactly the same shape cannot be obtained. Depending on how the dimensional variations of the flow path members occur, there may be a case where the balls do not pass through the flow-down path FL1. Therefore, in the actual assembly process, when fastening and fixing the first flow path member 162 to the base member 161, it is confirmed that the balls pass through the flow-down path FL1, and the first flow path member 162 is fastened and fixed at a position where the balls can pass. Thereafter, the second flow-down path member 163 is fastened and fixed to the columnar fastening portion 162c of the first flow path member 162 and the specific columnar fastening portion 161c of the base member 161.

[0225] Thus, it is preferable to provide an adjustment width within a certain range for the fixing position of the first flow path member 162 with respect to the base member 161. In the present embodiment, the difference between the inner diameter of the insertion hole 162b and the outer diameter of the fastening screw inserted into the insertion hole 162b can be used as the adjustment width. Note that regardless of the value of this adjustment width, since the second flow path member 163 is directly fastened and fixed to the first flow path member 162 in the vicinity of the connection position of the flow-down path FL1, it is possible to easily ensure the shape of the flow-down path FL1.

[0226] In this case, the adjustment width of the first flow path member 162 also affects the second flow path member 163. Here, as described above, not only arranging the second flow path member 163 to face the back surface of the base member 161, but also fitting it can improve the rigidity of the second flow path member 163. However, when the fitting portion is fixedly arranged on the base member 161, due to the influence of the adjustment width of the first flow path member 162, the positions of the fitting portion on the base member 161 side and the fitting portion on the second flow path member 163 side may be displaced, and assembly failure may occur.

[0227] Considering this displacement, the fitting portion on the base member 161 side and the fitting portion on the second flow path member 163 side may be fitted with a clearance fit. However, the larger the clearance, the lower the effect of strengthening the rigidity of the second flow path member 163, which is not preferable.

[0228] On the other hand, in this embodiment, the fitting portion on the base member 161 side is provided on the adjustment member 165, and the adjustment member 165 is configured to be adjustable in arrangement with an adjustment width exceeding the adjustment width of the first flow path member 162. Thus, the displacement of the fitting portion caused by the position adjustment of the first flow path member 162 can be offset, and assembly failure can be avoided.

[0229] In this case, since it is not necessary to ensure a sufficient clearance between the fitting hole 165b of the adjustment member 165 and the fitting convex portion 163d of the second flow path member 163, by fitting in a state with a small clearance, the rigidity of the second flow path member 163 can be sufficiently strengthened.

[0230] According to this embodiment, as shown in FIG. 12, the difference between the dimensions of the base member 161 and the dimensions of the adjustment member 165 is utilized as the adjustment width. For example, the width wa1 of the protrusion 161d of the base member 161 is configured to be shorter than the width wa2 of the outer diameter recessed portion 165g of the adjustment member 165, so that the adjustment width can be ensured (wa1 < wa2).

[0231] Also, for example, the width wb1 of the recessed portion 161e of the base member 161 is configured to be longer than the width wb2 of the plate-like portion 165a of the adjustment member 165, so that the adjustment width can be ensured (wb1 > wb2).

[0232] Further, with the fastening and fixing of the adjustment member 165, the adjustment hole 165f is supported by the specific columnar fastening portion 161c in a non-detachable manner, the fitting convex portion 163b is inserted into the fitting hole 165b, and the back surface of the plate-shaped portion 165a is supported so as to be able to contact the front-side end portion of the semi-formed portion 163a of the second flow path member 163, thereby being fixed between the base member 161 and the second flow path member 163.

[0233] Therefore, a dedicated fastener for fastening and fixing the adjustment member 165 can be made unnecessary, so that the product cost can be reduced by reducing the fasteners, and the assembly man-hours can be reduced.

[0234] Returning to FIG. 5 for explanation. The operation unit 300 is disposed on the back side of the game board 13, and various light-emitting means and various operation units are disposed inside. Hereinafter, the operation unit 300 will be described.

[0235] FIGS. 15 and 16 are front views of the operation unit 300, and FIG. 17 is a front perspective view of the operation unit 300. In FIGS. 15 and 17, a state where each movable member (each movable accessory) of the first operation unit 400 and the second operation unit 700 is disposed at the standby position is illustrated, and in FIG. 16, a state where each movable member (each movable accessory) of the first operation unit 400 and the second operation unit 700 is disposed at the protruding position protruding in front of the third symbol display device 81 is illustrated.

[0236] As shown in FIGS. 15, 16, and 17, the operation unit 300 has movable accessories that vertically displace the front side of the third symbol display device 81 arranged vertically, and the movable accessories arranged vertically have different shapes and operation modes from each other.

[0237] The movable members arranged vertically are configured to be independently drivable, and when both are arranged at the protruding position, they are configured to hide most of the display area of the third symbol display device 81. In other words, when either the movable member arranged on the upper side or the movable member arranged on the lower side is arranged at the protruding position, the other range of the third symbol display device 81 is not hidden by the movable member, and in addition to being able to execute a liquid crystal effect using this range, an effect combining the liquid crystal effect and the movable member arranged at the protruding position can be executed.

[0238] Also, although details will be described later, the movable members arranged on the lower side are configured such that a plurality (four in this embodiment) of movable members are arranged side by side in the left - right direction and each is independently configured to be vertically movable. Therefore, in addition to the state where all the movable members are arranged at the protruding position (see Fig. 16), a state where only some (for example, the left - end) of the movable members are arranged at the protruding position, a state where the movable members are arranged at different vertical heights at positions between the protruding position and the standby position, etc. can be configured.

[0239] Fig. 18 is an exploded front perspective view of the operation unit 300. The operation unit 300 includes a back case 310 formed in a box shape with an open front side, which is formed by a bottom wall portion 311 and an outer wall portion 312 erected from the outer edge of the bottom wall portion 311.

[0240] The back case 310 is formed in a rectangular frame shape when viewed from the front by forming a rectangular opening 311a at the center of the bottom wall portion 311. The opening 311a is formed to have a size corresponding to the outer shape (outer edge) of the display area of the third symbol display device 81 (that is, capable of partitioning the display area of the third symbol display device 81 when viewed from the front).

[0241] The operation unit 300 houses, in the internal space of the back case 310, a first operation unit 400 in which the movable member is displaceably arranged along a path including the lower side of the opening 311a, left - and right - hand effect units 600 arranged on both the left and right sides of the opening 311a for performing light - emitting effects, etc., and a second operation unit 700 in which the movable member is displaceably arranged along a path including the upper side of the opening 311a, and is configured as one unit.

[0242] Specifically, the first operation unit 400 is disposed on the bottom wall portion 311 of the back case 310 at a position below the opening 311a, and the second operation unit 700 is disposed on the bottom wall portion 311 of the back case 310 at a position above the opening 311a. In FIG. 18, a state in which the first operation unit 400 and the second operation unit 700 are disassembled from the back case 310 is illustrated.

[0243] The left and right effect units 600 include a decorative substrate having a light emitting means such as an LED inside. The decorative substrate is disposed obliquely, and it is characterized in that the optical axis of the light emitting means inclines so as to go toward the left and right inside as it approaches the player side. Thereby, since the optical axis of the light emitting means intersects on the front side for the player, the light irradiated from the left and right effect units 600 can be visually recognized three-dimensionally.

[0244] The back case 310 is extended as a flat plate along the back surface of the game board 13 (for example, arranged in parallel) at the front end of the outer wall portion 312, and includes a support plate portion 313 that supports the game board 13 in a surface contact manner in the assembled state (see FIG. 2).

[0245] The support plate portion 313 includes a positioning convex portion 313a that protrudes toward the front side in a shape that can be fitted with a fitting concave portion (not shown) formed on the base plate 60 of the game board 13, and a plurality of insertion holes 313b that are formed so as to allow a fastening screw fastened to the base plate 60 to pass through.

[0246] By fitting the positioning convex portion 313a into the fitting concave portion of the base plate 60, the back case 310 is positioned with respect to the base plate 60. By inserting the fastening screw into the insertion hole 313b and screwing it into the base plate 60, the game board 13 and the operation unit 300 can be integrally fixed, so that the rigidity of the entire game board 13 and the operation unit 300 can be improved.

[0247] Note that the shape of the positioning convex portion 313a is not limited in any way, and various forms are exemplified. For example, a convex portion having an outer shape slightly smaller than the inner shape (circular or oval in this embodiment) of the fitting concave portion of the base plate 60 may be used, or a protrusion having a shape (even smaller outer shape) that increases the fitting gap may be used in consideration of the workability during assembly. Further, when the inner shape of the fitting concave portion is formed in a rectangular shape, it is naturally assumed that the shape of the positioning convex portion 313a will also be rectangular to correspond to it.

[0248] As shown in FIGS. 5 and 18, in this embodiment, support plate portions 313 are densely arranged on the left side and the upper side of the back case 310, and the formation of the support plate portions 313 is reduced on the right side and the lower side. This is the result of designing in consideration of the balance between improving the rigidity of the entire game board 13 and the operation unit 300 and the space efficiency.

[0249] That is, when the base plate 60 of the game board 13 is formed of a plywood in which veneer plates are stacked as in this embodiment, since the movable members disposed on the back side of the game board 13 cannot be visually recognized through the thickness of the base plate 60, the entire back side of the area where an opening can be formed (or recessed from the side surface) in the base plate 60 of the game board 13 becomes effective as an area for disposing the movable members in a visually recognizable manner.

[0250] On the other hand, at the locations where the support plate portions 313 are formed, the internal space of the back case 310 is eroded inward by the area of the support plate portions 313 in the front view, so that the area where the movable members can be disposed is reduced accordingly. Therefore, if it is possible to maintain the elimination of the strength problem even when the support plate portions 313 are omitted, it means that it is possible to avoid the limitation of the arrangement range of the movable members by omitting the support plate portions 313.

[0251] In this embodiment, a large number of support plate portions 313 are arranged on the left side and the upper side of the back case 310, which is related to the range of the area where the balls launched into the game area or the like can be visually recognized by the player. That is, the support plate portions 313 are formed at locations outside the range where the launched balls can be visually recognized.

[0252] More specifically, in the present embodiment, the ball launched from the ball launching unit 112a (see FIG. 4) passes between the inner rail 61 and the outer rail 62, passes through the return ball prevention member 68, and is introduced into the game area (see FIG. 2), and thereafter is configured to flow down the game area. In the ball shooting game, the most attention-grabbing part is the place where the ball passes, and usually, the attention paid to other outer regions (for example, the region on the opposite side of the third symbol display device 81 across the outer rail 62 and the inner rail 61) is low.

[0253] Therefore, it is considered that the attention of the player to the lower left and upper left with reference to the left convex arc formed by the outer rail 62 and the upper left and upper right with reference to the upper convex arc, which are the ranges where the ball cannot reach, is low.

[0254] In addition, in the present embodiment, the above-mentioned outer edge member 73 and the block-shaped member 74 whose surfaces with respect to the outer rail 62 at the lower left and upper left of the outer rail 62 are formed in a shape along the outer rail 62 and disposed on the front side of the game board 13 are made of a light-impermeable resin material. In addition to the fact that the game board 13 is originally composed of a veneer that is difficult to transmit light, it is configured so that the back side of the game board 13 cannot be visually recognized from the front side of the game board 13 through the outer edge member 73 or the block-shaped member 74. Therefore, it is considered that the attention of the player is further reduced.

[0255] In the present embodiment, the support plate portion 313 is preferentially disposed at these locations where the attention is low and at locations where visual recognition is impossible. Actually, also in the left side portion and the upper side portion where many support plate portions 313 are formed, the support plate portion 313 is formed near the corner of the back case 310, avoiding the central portion as the overhanging end portion of the outer rail 62.

[0256] In other words, by forming the support plate portion 313 and selecting the location where space is eroded from a location with low visibility (low production ability) in the first place, while achieving the effect of ensuring the rigidity of the operation unit 300 and the entire game board 13, it is possible to highly secure the degree of freedom in designing the area that enters the field of vision of the player who focuses on the ball.

[0257] From this perspective, since there is a common configuration in pachinko machines of rolling the ball launched by the ball launching unit 112a (see FIG. 4) along the outer rail 62 and introducing it into the game area, it is possible to easily arrange the ranges where the ball does not flow down in the lower left, upper left, and upper right portions.

[0258] In this embodiment, the support plate portion 313 extending from the lower outer wall portion 312 is disposed offset to the back side compared to the support plate portions 313 extending from the left, right, and upper outer wall portions 312. From this configuration, the positioning convex portions 313a formed on the left, right, and upper support plate portions 313 are fitted into the fitting concave portions formed on the back surface of the base plate 60. On the other hand, the positioning convex portions 313a formed on the lower support plate portion 313 are not directly fitted into the base plate 60, but a shaped portion corresponding to a ball flow-down unit (not shown) disposed on the back side of the base plate 60 is formed, and it is fitted into the shaped portion. That is, the positioning convex portion 313a disposed on the lower side of the back case 310 is indirectly fixed to the base plate 60 via the ball flow-down unit.

[0259] FIG. 19 is a front perspective view of the first operation unit 400, and FIG. 20 is a rear perspective view of the first operation unit 400. The first operation unit 400 includes a base member 401 that is fitted into and fastened to the back case 310 from the front side, and four composite operation units 402 having substantially the same configuration are fastened and fixed to positions side by side on the front side of the base member 401.

[0260] The composite operation unit 402 includes a rotating unit 500 formed in a substantially dice shape and configured to be rotatable about a horizontal axis, and a mechanism for vertically displacing the rotating unit 500. Hereinafter, the details of the composite operation unit 402 will be described.

[0261] FIGS. 21(a) and 21(b) are front perspective views of the composite operation unit 402, and FIGS. 22(a) and 22(b) are rear perspective views of the composite operation unit 402. In FIGS. 21(a) and 22(a), a state where the rotating unit 500 is disposed at the raised position is illustrated, and in FIGS. 21(b) and 22(b), a state where the rotating unit 500 is disposed at the lowered position is illustrated.

[0262] In the composite operation unit 402, a columnar member 431 guides the rotating unit 500 in the vertical direction, and a drive motor 441 generates a driving force for vertically operating the rotating unit 500. The electrical wiring DK1 guided inside the rotating unit 500 is composed of a bundle of a plurality of electric wires, hangs down through the side opposite to the side where the columnar member 431 is disposed, and is configured to be able to enter the wiring assisting means 460 while being slack. Hereinafter, each component of the composite operation unit 402 will be described.

[0263] FIGS. 23 and 24 are exploded front perspective views of the composite operation unit 402. In FIGS. 23 and 24, a state where the disassembly of the rotating unit 500 is omitted is illustrated.

[0264] As shown in FIGS. 23 and 24, the composite operation unit 402 mainly includes a support means 410 for supporting the rotation unit 500, a stacking means 420 laminated and fixed to the support means 410, a guiding means 430 for guiding the movement of the support means 410 by limiting the movement direction of the stacking means 420 to one direction (in this embodiment, the vertical direction), a driving means 440 having a driving motor 441 for generating a driving force for moving the support means 410, a split base member 442 for supporting the driving motor 441, a transmission means 450 configured to mesh with the driving gear 441a of the driving motor 441 and transmit the driving force, and a wiring auxiliary means 460 configured to arrange (accommodate) an electric wiring DK1 having a length corresponding to the movement amount of the support means 410 without entanglement or pinching.

[0265] The support means 410 includes a flat plate portion 411 formed in a flat plate shape, an annular protrusion 412 protruding annularly from the upper surface of the flat plate portion 411, a deformed hole 413 formed as a through hole opened in the vertical direction at the central portion of the annular protrusion 412, a front vertical portion 414 bent downward from the front edge portion of the flat plate portion 411, a left surface vertical portion 415 which is a plate-like portion connected to the left end of the front vertical portion 414 and bent downward from the left edge portion of the flat plate portion 411, and a connection plate portion 416 having a through long hole 416a formed as a long hole extending in the front-rear direction at the lower end portion of the left surface vertical portion 415 and through which a connecting member 454 of the transmission means 450 is inserted.

[0266] The stacking means 420 mainly includes an end plate member 421 configured as a substantially front-rear symmetric plate-like member, a recessed portion 422 recessed at the front and rear end portions of the end plate member 421, a guiding cylindrical portion 423 configured in a cylindrical shape with a size that can be accommodated in the recessed portion 422, and a right lid member 424 disposed between the end plate member 421 and the support means 410 and fastened and fixed to the end plate member 421 to cover the recessed portion 422 from the right.

[0267] The guiding cylindrical portion 423 is only accommodated in the recessed portion 422 at the front end portion among the recessed portions 422 recessed at the front and rear end portions of the end plate member 421, and is not disposed (the arrangement is omitted) in the recessed portion 422 at the rear end portion.

[0268] Accordingly, similar to the case where the guide cylindrical portion 423 is disposed in both the front and rear recessed portions 422, when the rotating unit 500 is disposed at the lowered position or the raised position, the posture deviation occurring at the front end portion farthest from the rear end portion (see FIG. 34(c)) supported by the transmission means 450 can be minimized, so that the arrangement of the rotating unit 500 can be stabilized.

[0269] Furthermore, compared to the case where the guide cylindrical portion 423 is disposed in both the front and rear recessed portions 422, the gap between the recessed portion 422 and the columnar member 431 can be made larger at the rear end portion supported by the transmission means 450, so that the resistance generated when the stacking means 420 moves up and down can be reduced.

[0270] The right lid member 424 includes a pair of insertion holes 424a through which fastening screws for fastening and fixing to the end plate member 421 are inserted, a plurality of insertion openings 424b formed so as to be openable so that fastening screws for passing through the right lid member 424 from the side of the end plate member 421 and fastening and fixing to the left surface vertical portion 415 of the support means 410 can be inserted, and a recessed support portion 424c recessed so as to be able to receive the guide cylindrical portion 423 of the stacking means 420 in a shape that prevents it from falling off in the vertical direction.

[0271] The guiding means 430 mainly includes a pair of front and rear columnar members 431 made of metal that pass through at least one of the guide cylindrical portion 423 or the recessed portion 422, a metal plate portion 432 disposed on the left surface of the columnar member 431 and composed of a metal plate, an upper bent portion 433 bent rightward from the upper side portion of the metal plate portion 432, a lower bent portion 434 bent rightward from the lower side portion of the metal plate portion 432, and a rear bent portion 435 bent rightward from the rear side portion of the metal plate portion 432.

[0272] The metal plate portion 432 is notched from the upper part downward and formed in a U-shape when viewed from the left side. As a result, an assembly worker or a maintenance worker can reach the front-rear intermediate portion of the end plate member 421 (the portion between the pair of front-rear recessed portions 422) through the notched range, so that the efficiency of the assembly work or the maintenance work can be improved. Details will be described later.

[0273] The metal plate portion 432 is disposed in proximity to the end plate member 421 in the left-right direction at locations excluding the central portion in the front-rear direction. Thus, even if the end plate member 421 is displaced in the left-right direction, the displacement can be restricted not only by contact with the columnar member 431 but also by contact with the metal plate portion 432.

[0274] As a result, displacement of the stacking means 420 in the left-right direction can be suppressed, so that displacement of the support means 410 fastened and fixed to the stacking means 420 and displacement of the transmission means 450 connected to the support means 410 in the left-right direction can be suppressed.

[0275] The upper bent portion 433 and the lower bent portion 434 are through holes formed at overlapping positions when viewed in the up-down direction, and are provided with support holes 433a and 434a formed to have a size capable of inserting and supporting the columnar member 431.

[0276] In the assembled state, the columnar member 431 is inserted into the support holes 433a and 434a, and the end portions are formed to have a length slightly protruding from above the upper bent portion 433 and below the lower bent portion 434 (see Fig. 21(a)). By fitting a so-called "E-ring" into a groove portion formed to be recessed from the outer diameter direction in this slightly protruding portion, the columnar member 431 is prevented from coming out of the support holes 433a and 434a.

[0277] The lower bent portion 434 stably supports the divided base member 442 in a state of supporting it from below. In this supported state, the rear side plate portion of the divided base member 442 overlaps with the rear bent portion 435 in the front-rear direction, and a fastening screw inserted from the rear side through the base member 401 (see FIG. 20) disposed on the rear side of the divided base member 442 is fastened and fixed to the female screw portion formed in the rear bent portion 435, whereby the base member 401, the divided base member 442, and the guiding means 430 can be integrally fixed.

[0278] The driving means 440 has components arranged separately on the left and right for each function by the partition plate portion 442a of the divided base member 442. That is, on the left side of the partition plate portion 442a, a configuration for transmitting a driving force (such as the transmission means 450, etc.) is arranged, and on the right side of the partition plate portion 442a, a configuration for power supply or a configuration to which power is supplied (the main body portion of the drive motor 441, the wiring auxiliary means 460 in which the electrical wiring DK1 is housed, etc.) is arranged. In FIGS. 23 and 24, although the illustration of the electrical wiring DK1 used for power supply is omitted, the details of the relationship and displacement between the electrical wiring DK1 and the wiring auxiliary means 460 will be described later.

[0279] The drive motor 441 is attached to the partition plate portion 442a from the right side, and the drive gear 441a projects to the left side of the partition plate portion 442a through an opening formed in the partition plate portion 442a. When the drive motor 441 is driven and the drive gear 441a rotates in the assembled state (see FIG. 21), a driving force is transmitted to the transmission means 450 via the transmission gear 451 that meshes with the drive gear 441a.

[0280] The partition plate portion 442a mainly includes a plurality of protruding portions 442b protruding columnarly from the left surface to the left, a metal cylindrical portion 442c made of metal and formed in a cylindrical shape with an axis parallel to the protruding direction of the protruding portion 442b at the upper end and fixed above the protruding portion 442b, a detection sensor 442d in the form of a photocoupler fastened and fixed in a posture where a detection groove is disposed opposite to the metal cylindrical portion 442c, and an opening 442e formed in the left-right direction.

[0281] The protruding portions 442b are each configured to be able to pivotally support the transmission gear 451 and the intermediate gear 452, and female threads are formed at the protruding tips. By fastening and fixing a fastening screw with a flange to the female threads, the transmission gear 451 and the intermediate gear 452 can be pivotally supported so as not to fall off. The metal cylindrical portion 442c is formed with a diameter capable of pivotally supporting the rotating arm member 453.

[0282] The detection sensor 442d is configured to be able to detect that the detected plate portion 453d of the rotating arm member 453 is disposed in the detection groove. Thereby, the position of the rotating arm member 453 can be detected.

[0283] The opening 442e is an opening for guiding the electrical wiring DK1 that has reached between the divided base member 442 and the wiring assisting means 460 in the left - right direction and to the back side. Details will be described later.

[0284] The transmission means 450 mainly includes a transmission gear 451 that meshes with the drive gear 441a, an intermediate gear 452 that is disposed above the transmission gear 451 (on the side opposite to the drive gear 441a) and meshes with the transmission gear 451, a rotating arm member 453 having a gear portion 453a that meshes with the intermediate gear 452, and a connecting member 454 that is supported in a non - detachable manner at the rotating tip of the rotating arm member 453.

[0285] The rotating arm member 453 is a member that is rotatably supported by the metal cylindrical portion 442c of the partition plate portion 442a, and includes a gear portion 453a formed in a gear - tooth shape along an arc centered on the rotation axis, an extending arm portion 453b that extends radially outward at a position axially offset from the gear portion 453a, a support hole 453c formed with an opening in a direction parallel to the rotation axis at the extending tip of the extending arm portion 453b, and a detected plate portion 453d that extends along the rotation direction from the extending arm portion 453b.

[0286] The connecting member 454 mainly includes a brass cylindrical supported portion 454a whose tip side is inserted into the through long hole 416a, and a fitting lid portion 454b made of synthetic resin that is fitted on the base end side of the 454a and has a flange portion 454c that projects in a flange shape at the base end side end portion.

[0287] A well-known E-ring (not shown) is fitted into the tip end portion of the supported portion 454a. Thereby, it is possible to prevent the connecting member 454 from falling off leftward from the through long hole 416a. Therefore, it is possible to prevent the connecting member 454 from falling off and being lost in the state before the lamination means 420 and the guiding means 430 are assembled to the divided base member 442 (the state during assembly).

[0288] In the assembled state (see Fig. 22(a)), the right lid member 424 is arranged opposite to the left side of the connecting member 454 (arranged so as to overlap in the left-right direction), thereby physically restricting the leftward drop of the connecting member 454.

[0289] The outer diameter of the fitting lid portion 454b is formed shorter than the vertical width of the through long hole 416a, and the outer diameter of the flange portion 454c is formed longer than the vertical width of the through long hole 416a. Thereby, by disposing the resin-made fitting lid portion 454b between the through long hole 416a and the metal-made supported portion 454a, deformation of the through long hole 416a can be suppressed. In addition, since the flange portion 454c is configured to have a dimension that cannot pass through the through long hole 416a, it is possible to prevent the connecting member 454 from falling off rightward from the through long hole 416a.

[0290] The wiring assisting means 460 is configured in a bottomed container shape from two members arranged corresponding to each other in the left-right direction. That is, the wiring assisting means 460 mainly includes a left side member 461 that is arranged opposite to the right side surface of the partition plate portion 442a and is fastened and fixed to the partition plate portion 442a, and a right side member 468 that is arranged opposite to the right side surface of the left side member 461 and is shaped so as to be able to cover the internal shape of the left side member 461 in a left-right direction view and is fastened and fixed to the left side member 461.

[0291] The left member 461 is fastened and fixed to a portion that is raised rightward at the front and rear positions of the partition plate portion 442a, and mainly includes a plate-shaped opposing plate 462 arranged opposite to it, a strip-shaped extending portion 463 that extends rightward in a strip shape from the front and rear edges and the lower edge of the opposing plate 462, a support column portion 464 that protrudes rightward in a columnar shape near the upper end portion of the opposing plate 462 and has a female screw formed at the protruding tip portion, and a wiring support portion 465 that is configured in a shape through which a thin-diameter member such as a bundling band for supporting the electrical wiring DK1 can be inserted on the diagonally upper rear side of the support column portion 464.

[0292] As described above, since the opposing plate 462 is fastened and fixed to the raised portion of the partition plate portion 442a, a gap is generated between the opposing plate 462 and the partition plate portion 442a at the front and rear intermediate position (position other than the raised portion) of the partition plate portion 442a. This gap functions as a gap through which the electrical wiring DK1 passes.

[0293] The electrical wiring DK1 (see FIGS. 21 and 22), although details will be described later, passes through the opening 442e, passes through the gap between the partition plate portion 442a and the wiring auxiliary means 460, passes through the wiring support portion 465, passes from the rear side to the lower side of the support column portion 464, and is supported by the support means 410 and the rotation unit 500 upward toward the front side of the support column portion 464.

[0294] Therefore, the electrical wiring DK1 requires a length (extra length) that can correspond to the vertical movement of the support means 410 and the rotation unit 500. When the support means 410 and the rotation unit 500 are arranged at the lowered position, this extra-length electrical wiring DK1 is accommodated in the wiring auxiliary means 460 in a state of being loosely wound around the support column portion 464.

[0295] Here, in the present embodiment, the shape of the wiring assisting means 460 is designed such that the load applied to the electrical wiring DK1 loosely wound around the support column portion 464 is reduced. That is, when the electrical wiring DK1 is wound around the support column portion 464, the longer the length of the wound electrical wiring DK1, the larger the maximum diameter of the electrical wiring DK1 centered on the support column portion 464. Thus, if the distance between the strip-shaped extended portion 463 and the electrical wiring DK1 is short, there is a possibility that a load as a reaction force is generated from the strip-shaped extended portion 463 to the electrical wiring DK1. In the present embodiment, the strip-shaped extended portion 463 is disposed with a sufficient interval in the radial direction of the support column portion 464.

[0296] In particular, as will be described later, in the present embodiment, the downward extended portion 519 as a portion for supporting the electrical wiring DK1 at a position close to the wiring assisting means 460 in the rotating unit 500 is disposed on the front side of the support column portion 464. Therefore, as the support means 410 and the rotating unit 500 move to the lowered position, the extra length of the electrical wiring DK1 is mainly disposed on the front side of the support column portion 464.

[0297] Correspondingly, the strip-shaped extended portion 463 is designed such that, with the support column portion 464 as a reference in the front-rear direction, a larger internal space can be secured on the front side of the support column portion 464. Further, the strip-shaped extended portion 463 includes a functional curved surface 463a which is a surface that is displaced downward toward the front side below the support column portion 464 and has the center of the radius of curvature disposed on the lower side.

[0298] Due to its shape, the functional curved surface 463a can apply a load in an obliquely upward front direction as a reaction force to the nearby electrical wiring DK1. Thereby, the electrical wiring DK1 can be made to easily gather in the front side range with respect to the support column portion 464.

[0299] In addition, since the functional curved surface 463a is formed in a curved shape protruding inward of the wiring assisting means 460, it is possible to easily secure a space for arranging the drive motor 441. That is, due to the curved shape of the functional curved surface 463a, in addition to being able to stabilize the arrangement of the electrical wiring DK1, the wiring assisting means 460 and the drive motor 441 can be arranged in a minimum space.

[0300] FIG. 25 is an exploded front perspective view of the rotating unit 500, and FIG. 26 is an exploded rear perspective view of the rotating unit 500. As shown in FIGS. 25 and 26, the rotating unit 500 mainly includes a fixing means 510 that is fastened and fixed to the supporting means 410 (see FIG. 23) and is formed in a U-shaped shape when viewed from the front, both-end fixing means 520 that are fixed inside the fixing means 510 and constitute a rotation center portion, a shaft constituting means 530 that is fixed to the both-end fixing means 520 and is disposed inside the U-shaped shape of the fixing means 510, a rotating left lid portion 550 that is disposed inside the U-shaped shape of the fixing means 510 and on the left side of the shaft constituting means 530, a rotating body 560 that is fastened and fixed to the rotating left lid portion 550 and has an outer shape that is substantially a rectangular parallelepiped shape, and a rotating right lid portion 570 that is fastened and fixed to the right side of the rotating body 560 and is disposed inside the U-shaped shape of the fixing means 510.

[0301] To explain the outline of the rotating unit 500, it is mainly composed of a rotating portion that rotates and displaces about a left-right direction axis mainly including the rotating body 560, and a fixing portion that supports the rotating portion mainly including the fixing means 510.

[0302] The rotating portion is composed of the rotating body 560, the rotating left plate 550, a motor gear 542 that meshes with the rotating left plate 550, and a driven plate 575 of the rotating right lid portion 570, and other configurations (the fixing means 510, the both-end fixing means 520, the shaft constituting means 530 excluding the motor gear 542, and the posture fixing bush 571 of the rotating right lid portion 570) excluding these constitute the fixing portion.

[0303] The fixing means 510 mainly includes a U-shaped metal plate 511 formed in a U shape when a metal plate is bent at a right angle, left and right fixing covers 514 arranged opposite to each other on the left and right of the U-shaped metal plate 511 and configured in a shape capable of forming a closed cross-section between the U-shaped metal plate 511, and a guide member 516 fastened and fixed from below the U-shaped metal plate 511 to guide the electrical wiring DK1.

[0304] In the description of the left and right fixing covers 514, the closed cross-section does not assume a complete seal (adhesion), and any closing method suitable for the purpose in this embodiment is acceptable. That is, in this embodiment, since the electrical wiring DK1 will pass through the closed cross-section, an opening that prevents the passage of the electrical wiring DK1 (for example, an opening with a smaller opening diameter than the thickness of the electrical wiring DK1, or an opening whose width is larger than the thickness of the electrical wiring DK1 and whose direction is along the longitudinal direction of the electrical wiring DK1 so that the accommodation of the electrical wiring DK1 is maintained) is acceptable. The details of the path of the electrical wiring DK1 will be described later.

[0305] Female threads and positioning through holes are formed at appropriate positions on the long plate-shaped portion of the U-shaped metal plate 511, which are used for alignment and fastening and fixing with the left and right fixing covers 514 and the guide member 516.

[0306] Both ends of the plate of the U-shaped metal plate 511 are arranged opposite to each other, and are notched into different shapes on the left and right. That is, on the left side, a substantially circular first opening 512 is formed, while on the right side, a substantially ladle-shaped second opening 513 and a pair of circular holes 513a are formed.

[0307] The guide member 516 mainly includes an irregular hole 517 drilled in a substantially ladle shape in the vertical direction at the central position in the left-right direction, a lowering bottom portion 518 configured to leave a gap with the U-shaped metal plate 511 on the right of the irregular hole 517, and a downward extending portion 519 extending downward from the right rear end portion of the lowering bottom portion 518.

[0308] The irregular hole 517 is located above the irregular hole 413 (see FIG. 23), and is formed in a size capable of guiding the electrical wiring DK1. The electrical wiring DK1 passing above the irregular hole 517 is disposed between the lowering bottom portion 518 and the U-shaped metal plate 511, bends upward, is disposed between the U-shaped metal plate 511 and the left and right fixing covers 514, and is disposed on the inner diameter side of the right fixing bush 522 of the both-end fixing means 520, and is disposed inside the U-shaped metal plate 511. The state of the electrical wiring DK1 in its path will be described later.

[0309] The downward extending portion 519 is a portion configured in a shape capable of supporting the electrical wiring DK1 on the side that moves up and down corresponding to the up and down movement with a binding band. That is, a forming portion 411a is formed to the immediate right of the irregular hole 413 of the flat plate portion 411 in a shape capable of fixing the binding band. The electrical wiring DK1 is fixed by a binding band to the forming portion 411a, and is fixed by a binding band to the downward extending portion 519 disposed on the back side and below the forming portion 411a.

[0310] Thereby, since the electrical wiring DK1 can be moved closer to the back side, it is possible to avoid the electrical wiring DK1 being displaced to the front side and being pinched between the front upper edge portion of the strip-shaped extending portion 463 and the front vertical portion 414 of the support means 410 (see FIG. 23).

[0311] Among the configurations of the downward extending portion 519, the plate portion constituting the right side surface functions as a restricting portion for preventing the binding band from rising. That is, the binding band is maintained in a state of being fixed to the U-shaped portion projecting downward at the lower end portion of the downward extending portion 519, and by restricting the rising of the binding band, the fixing position of the electrical wiring DK1 with respect to the downward extending portion 519 can be limited to the vicinity of the lower end portion of the downward extending portion 519.

[0312] The both-end fixing means 520 includes a left fixing bush 521 fitted into the first opening 512 of the U-shaped metal plate 511 from the left side, and a right fixing bush 522 fitted into the second opening 513 from the right side.

[0313] The left fixed bush 521 and the right fixed bush 522 are provided with forming portions (projections) that are fitted into notches (recesses) formed above and below both the first opening 512 and the second opening 513. The stability of the posture is achieved by the fitting of these uneven portions, and the positioning in the axial direction (left - right direction) is achieved by a flange - shaped portion formed to have a diameter larger than the inner diameters of the first opening 512 and the second opening 513.

[0314] That is, in the assembled state (see Fig. 21), the left fixed bush 521 and the right fixed bush 522 are supported by arranging the flange - shaped portion between the U - shaped metal plate 511 and the left - right fixed lid 514, and the posture is fixed by the fitting of the uneven portions.

[0315] The left fixed bush 521 has a support hole 521a with a D - shaped cross - section drilled at the position of the rotation axis. The support hole 521a is a portion that supports one end of the shaft configuration means 530, and the details will be described later.

[0316] The right fixed bush 522 mainly includes a pair of insertion holes 523 formed to allow the insertion of fastening screws inserted through the circular hole 513a, an annular protrusion 524 of a deformed shape that can be fitted into the second opening 513 and protrudes leftward, and an omitted portion 525 where the formation of the flange - shaped portion is omitted for the purpose of securing a passage for the electrical wiring DK1 in the substantially lower half.

[0317] The annular protrusion 524 is formed with a protruding length that exceeds the plate thickness of the U - shaped metal plate 511. Thereby, the alignment of the protruding fastening portion 532 of the shaft configuration means 530 can be easily performed, and the details will be described later.

[0318] The shaft forming means 530 mainly includes a right shaft main body 531 that is fastened and fixed to the U-shaped metal plate 511 by screwing a fastening screw inserted into the insertion hole 523, a left shaft main body 535 that is disposed opposite to the left side of the right shaft main body 531 and is fastened and fixed to the right shaft main body 531, a drive motor 541 that is fastened and fixed to the left shaft main body 535, a motor gear 542 that is fixed to the drive shaft of the drive motor 541, a decorative circuit board 543 that is disposed on the front side of the right shaft main body 531 and the left shaft main body 535, a light diffusing plate 545 that is laminated and disposed on the front side of the decorative circuit board 543, has a light diffusing shape formed on the back surface, and is positioned by being sandwiched between the right shaft main body 531 and the left shaft main body 535 from the front, back, left, right, and top and bottom, and a detection sensor 547 of the photocoupler type that is fastened and fixed to the right shaft main body 531 from the right side.

[0319] As described above, the shaft forming means 530 includes a plurality of components that require electrical supply (i.e., the drive motor 541, the decorative circuit board 543, and the detection sensor 547). Therefore, it is considered a problem to arrange the electrical wiring DK1 compactly. In contrast, in the present embodiment, all of the connection terminals 541a and 547a of the electrical wiring DK1 are gathered in the region between the opposing surfaces of the right shaft main body 531 and the left shaft main body 535.

[0320] That is, the connection terminal 541a of the drive motor 541 is disposed on the motor main body portion that is surrounded by the right shaft main body 531 and the left shaft main body 535, the connection terminal (not shown) of the decorative circuit board 543 is disposed on the back side facing the region between the opposing surfaces of the right shaft main body 531 and the left shaft main body 535, and the connection terminal 547a of the detection sensor 547 extends through the opening 533a of the right shaft main body 531 to the left side (the left shaft main body 535 side) of the right shaft main body 531.

[0321] As a result, as long as the electrical wiring DK1 is guided to the region between the opposing surfaces of the right shaft main body 531 and the left shaft main body 535, it is possible to supply electricity without excess or deficiency. Therefore, the electrical wiring DK1 can be housed in the region between the opposing surfaces of the right shaft main body 531 and the left shaft main body 535 (the region on the inner diameter side of the arc-shaped wall extending toward the other side).

[0322] Furthermore, the fastening directions of the fastening between the shaft forming means 530 and the U-shaped metal plate 511, the fastening between the right shaft main body 531 and the left shaft main body 535, the fastening between the left shaft main body 535 and the drive motor 541, and the fastening between the right shaft main body 531 and the detection sensor 547 are unified in the left-right direction (the direction parallel to the rotation axis). Therefore, it is easy to configure the radial dimension of the shaft forming means 530 to be small.

[0323] In this way, in addition to being able to integrate the main functional parts by the shaft forming means 530, the electrical wiring DK1 can be compactly housed. Hereinafter, the details of each configuration of the shaft forming means 530 will be described.

[0324] The right shaft main body 531 mainly includes a protruding fastening portion 532 that protrudes rightward in a pair in the front-rear direction and has a female screw formed at the protruding tip, an opening 533a that is drilled in the left-right direction with a size that allows the connection terminal 547a of the detection sensor 547 to pass through at a position below the protruding fastening portion 532, a wiring opening 533b that is drilled in the left-right direction with a size that allows the electrical wiring DK1 (and the connector disposed at the tip) to be inserted through at a position above the protruding fastening portion 532, and a pair of locking claw portions 534 that protrude in a claw shape at a position with a gap on the front side of the front plate portion of the right shaft main body 531.

[0325] The protruding fastening portion 532 is fixed in posture by loosely fitting with the annular protrusion 524 of the right fixing bush 522, the tip portion abuts against the U-shaped metal plate 511, and is fastened and fixed to the U-shaped metal plate 511 by screwing in the fastening screw inserted through the circular hole 513a and the insertion hole 523. In addition, the protruding fastening portion 532 is inserted through the insertion hole 572 of the posture fixing bush 571, and the details will be described later.

[0326] The locking claw portion 534 is a portion for supporting the electrical decoration substrate 543 and the light diffusion plate 545 so as to sandwich them from the left-right direction in the assembled state (see FIG. 21). In addition, a pair of regulating protrusions 534a that protrude forward on the upper and lower ends of the front plate portion sandwich the electrical decoration substrate 543 and the light diffusion plate 545 (directly or indirectly), so that the displacement in the up-down direction can be regulated.

[0327] The left shaft main body 535 mainly includes a plate-like portion 536 formed in a plate shape intersecting at a right angle with the rotation axis (left-right direction axis), a pair of protruding fastening portions 537 protruding in a columnar shape to the right from the plate-like portion 536 and having female threads formed at the protruding tips, a shaft support portion 538 protruding in a columnar shape to the left along the rotation axis from the plate-like portion 536, and a pair of locking claw portions 539 protruding in a claw shape at positions with a gap on the front side of the front plate portion of the left shaft main body 535.

[0328] The protruding fastening portion 537 protrudes to the same plane as the plane where the right tip portion of the arc-shaped wall of the left shaft main body 535 is arranged. In this case, the arc-shaped wall of the left shaft main body 535 and the protruding fastening portion 537 can be brought into contact with the plate portion arranged in parallel with the plate-like portion 536, which is a constituent plate portion of the right shaft main body 531, in the same plane.

[0329] Thereby, the right shaft main body 531 can be stably arranged with respect to the left shaft main body 535, and the fastening screw inserted into the insertion hole formed in the right shaft main body 531 can be easily screwed into the female thread at the tip of the protruding fastening portion 537. Therefore, the right shaft main body 531 can be easily fastened and fixed to the left shaft main body 535.

[0330] The shaft support portion 538 is configured in a columnar shape with a diameter slightly shorter than that of the circular opening formed circularly at the center of the flanged gear 551 of the left rotating lid portion 550, thereby rotatably supporting the flanged gear 551. In addition, the shaft support portion 538 is formed in a D shape with a tip slightly smaller than the support hole 521a, and is configured to be fitted with the support hole 521a.

[0331] That is, in the assembled state (see FIG. 21), the shaft support portion 538 is non-rotatably supported by fitting with the support hole 521a and functions as a portion for rotatably supporting the left rotating lid portion 550.

[0332] The locking claw portion 539 has substantially the same shape as the locking claw portion 534 of the right shaft main body portion 531, and in the assembled state (see Fig. 21), it supports the electrical decoration substrate 543 and the light diffusing plate 545 by sandwiching them from the left and right directions. At this time, by sandwiching the electrical decoration substrate 543 and the light diffusing plate 545 between the front plate portion arranged with a gap on the back side and the locking claw portions 534 and 539, displacement in the front-rear direction can also be restricted.

[0333] In addition, at the upper and lower ends of the front plate portion, a pair of restricting protrusions 539a protruding to the front side sandwich the electrical decoration substrate 543 and the light diffusing plate 545 (directly or indirectly), thereby restricting displacement in the up-down direction.

[0334] Thereby, without preparing individual fixing means (for example, fastening screws) for fixing the electrical decoration substrate 543 and the light diffusing plate 545, by utilizing the shape design of the right shaft main body portion 531 and the left shaft main body portion 535, along with the fastening and fixing of the right shaft main body portion 531 and the left shaft main body portion 535, the electrical decoration substrate 543 and the light diffusing plate 545 can be fixed to the right shaft main body portion 531 and the left shaft main body portion 535.

[0335] The electrical decoration substrate 543 is provided with a plurality of LED members 544 arranged vertically side by side at the left end, and the LED members 544 are arranged such that the optical axes extend rightward along the surface of the electrical decoration substrate 543. The plurality of LED members 544 are configured such that the emission colors of the respective LEDs (for example, red, green, blue) are different, and with the combination of their emission colors, a plurality of color emission effects can be executed with a small number of LEDs.

[0336] The light diffusing plate 545 has a light diffusing shape formed on the back surface, and this light diffusing shape is formed such that light can be surface-emitted in the direction perpendicular to the surface of the light diffusing plate 545. Thereby, while reducing the number of LED members 544, the rotating body 560 irradiated with the light transmitted through the light diffusing plate 545 can be illuminated evenly.

[0337] The detection sensor 547 is disposed on the right side inside the rotating body 560, which is opposite to the left side where components for transmitting driving force such as the drive motor 541 and the transmission gear 552 are arranged. As a result, the space inside the rotating body 560 can be effectively utilized, and it can be arranged compactly.

[0338] By disposing the detection sensor 547 inside the rotating body 560, the displacement of the detection sensor 547 associated with the lifting and lowering displacement of the rotating body 560 can be easily executed. In other words, when the detection sensor 547 is arranged outside the rotating body 560, the member supporting the detection sensor 547 is almost always arranged outside the rotating body 560. In this case, however, in order to lift and lower the detection sensor 547 along with the lifting and lowering displacement of the rotating body 560, it is necessary to displace the member supporting the detection sensor 547 as well.

[0339] On the other hand, when the detection sensor 547 is disposed inside the rotating body 560 as in this embodiment, by disposing the detection sensor 547 on the member constituting the rotation axis of the rotating body 560, it can be configured such that the detection sensor 547 is lifted and lowered along with the lifting and lowering displacement of the rotating body 560 (the lifting and lowering displacement of the member constituting the rotation axis).

[0340] The detection sensor 547 is disposed in a posture where the detection groove faces the tangential direction of a circle centered on the rotation axis of the rotating body 560. As a result, it can be configured such that the detected portion 577 protruding axially from the eccentric position of the rotating body 560 passes through the detection groove.

[0341] The left rotating lid portion 550 mainly includes a gear 551 with a flange pivotally supported by the shaft support portion 538 and a driven plate 555 fixed in the rotation direction with respect to the gear 551 with a flange.

[0342] The flanged gear 551 mainly includes a transmission gear 552 that is arranged to mesh with the motor gear 542, a stepped disk portion 553 that extends radially outward from the axial end of the transmission gear 552 and is formed in a stepped disk shape, and a plurality of protruding portions 554 that protrude from a specific position on the outer circumference of the small-diameter circle of the stepped disk portion 553 (in this embodiment, positions at 120-degree intervals that divide the circumference into three equal parts) toward the outer circumference of the large-diameter circle.

[0343] The driven plate 555 is provided with an irregular opening 556 that is drilled in a shape slightly larger than the shape that continuously connects the outer shape of the small-diameter circle of the stepped disk portion 553 and the protruding portions 554 when viewed in the rotational axis direction.

[0344] By fitting the irregular opening 556 onto the small-diameter circle of the stepped disk portion 553 and the protruding portions 554, it is possible to prevent the driven plate 555 from shifting in the rotational direction with respect to the flanged gear 551.

[0345] Also, since the large-diameter circle of the stepped disk portion 553 is made larger than the irregular opening 556, the flanged gear 551 is restricted from penetrating the irregular opening 556 to the right.

[0346] The shape of the left side surface of the flanged gear 551 is designed such that there is a gap between it and the U-shaped metal plate 511 when it is in contact with an overhanging portion that is formed to project annularly to the right from around the support hole 521a of the left fixed bush 521.

[0347] Thereby, when the rotating body 560 rotates, the left side surface of the flanged gear 551 can be configured to rub only against the annular overhanging portion of the left fixed bush 521, and rubbing between the flanged gear 551 and the U-shaped metal plate 511 can be avoided. Therefore, wear of the flanged gear 551 can be suppressed.

[0348] The rotating body 560 is formed of a light-transmissive resin material and includes four plate-like members on the surface of which different or identical patterns and figures are formed. It forms a substantially cubic shape by being fastened and fixed to the rotating left lid portion 550 and the rotating right lid portion 570. Details will be described later.

[0349] The rotating right cover portion 570 mainly includes a posture fixing bush 571 having a pair of insertion holes 572 through which the protruding fastening portion 532 of the shaft configuring means 530 can be inserted, and a driven plate 575 rotatably supported by the posture fixing bush 571.

[0350] Similar to the stepped disc portion 553 of the flanged gear 551, the outer peripheral surface of the posture fixing bush 571 is configured such that the outer diameters are different. That is, the right end portion is configured to have a larger diameter compared to its left side portion, thereby defining the limit position when the driven plate 575 is displaced to the right with respect to the posture fixing bush 571. Thereby, it is possible to prevent the driven plate 575 from falling off the posture fixing bush 571.

[0351] The driven plate 575 mainly includes a supported shaft hole 576 formed in a circular shape slightly larger than the small diameter circle of the posture fixing bush 571 at the central portion, and a detected portion 577 protruding leftward along an arc shape concentric with the central axis of the supported shaft hole 576.

[0352] The driven plate 575 is disposed in a gap (see Fig. 30(a)) between the right end portion of the arc-shaped portion disposed on the right side of the shaft right main body portion 531 and the flange-shaped portion of the posture fixing bush 571, so that displacement in the rotation axis direction (left-right direction) is restricted.

[0353] In addition, since the driven plate 575 is supported in a manner of sliding on the outer peripheral surface of the large diameter cylindrical portion of the posture fixing bush 571, it is possible to achieve stabilization of the posture during rotation as compared with the case of being pivotally supported by a thin diameter rotating shaft.

[0354] The detected part 577 is arranged in the assembled state (see Fig. 21) so as to be able to enter the detection groove of the detection sensor 547. By determining the presence or absence of the detected part 577 by the detection sensor 547 (whether the detected part 577 has entered the detection groove of the detection sensor 547 or the non-formation range of the detected part 577 faces the detection sensor 547, so that it has not entered the detected part 577), the MPU 221 of the voice lamp control device 113 can be made to determine the posture of the rotating body 560.

[0355] Fig. 27 is an exploded front perspective view of the rotating left lid part 550 and the rotating body 560, and Fig. 28 is an exploded front perspective view of the rotating body 560 and the rotating right lid part 570. In Fig. 27, the opposing surfaces of the rotating left lid part 550 and the rotating body 560 are illustrated in a posture facing the front side, and in Fig. 28, the opposing surfaces of the rotating right lid part 570 and the rotating body 560 are illustrated in a posture facing the front side. That is, it is illustrated in an arrangement where the front side moves away with the rear side of the opposing surface as the axis.

[0356] Since the rotating body 560 is formed in a rectangular cylindrical shape by a plurality (four in this embodiment) of surface constituent members 560a to 560d having similar shapes, the surface constituent member 560a will be described in detail, and only the differences for the other surface constituent members 560b to 560d will be described, with the detailed description being omitted.

[0357] The surface constituent member 560a includes a substantially square plate-like part 561 formed with a decorative pattern on the outer surface and constituting the outer wall of the rotating body 560, and a pair of symmetrically projecting parts 562 formed to project inward from the left and right end parts of the plate-like part 561 in a shape that is rotationally symmetric with respect to the center point of the plate-like part 561.

[0358] The symmetrically projecting part 562 mainly includes an opposing plate part 563 arranged to face the driven plate 555 or the driven plate 575, left and right opposing parts 564 laminated on the left and right inner sides of the opposing plate part 563 and projecting outward in the front and rear directions of the opposing plate part 563, a fastening auxiliary part 565 laminated on the left and right inner sides of the left and right opposing parts 564 to ensure the screwing-in thickness, and an alignment part 566 formed in the opposing plate part 563.

[0359] The plate-shaped part 561 has different decorative patterns on the surface constituent members 560a to 560d. As a result, as the rotating body 560 rotates and the surface constituent members 560a to 560d facing the player side change (periodically), a plurality of types (four types in this embodiment) of figures and patterns visible through the rotating body 560 can be changed.

[0360] Specifically, on the surface of the plate-shaped part 561 of the surface constituent member 560a, a decorative pattern composed of a figure indicating "△" (triangle) is formed. On the surface of the plate-shaped part 561 of the surface constituent member 560b, a decorative pattern composed of a figure indicating "?" (question mark) is formed. On the surface of the plate-shaped part 561 of the surface constituent member 560c, a decorative pattern composed of a figure indicating "!" (exclamation mark) is formed. On the surface of the plate-shaped part 561 of the surface constituent member 560d, a decorative pattern composed of a figure indicating "○" (circle) is formed.

[0361] In the composite operation unit 402 in which four are arranged side by side on the left and right (see FIG. 19), common decorative patterns are formed on the surface constituent members 560a, 560b, and 560d, while different decorative patterns are formed on the surface constituent member 560c.

[0362] That is, on the surface of the plate-shaped part 561 of the surface constituent member 560c of the composite operation unit 402 arranged on the far left, a decorative pattern composed of a figure indicating "H" is formed. On the surface of the plate-shaped part 561 of the surface constituent member 560c of the composite operation unit 402 arranged second from the left end, a decorative pattern composed of a figure indicating "I" is formed. On the surface of the plate-shaped part 561 of the surface constituent member 560c of the composite operation unit 402 arranged third from the left end, a decorative pattern composed of a figure indicating "T" is formed. On the surface of the plate-shaped part 561 of the surface constituent member 560c of the composite operation unit 402 arranged on the far right, a decorative pattern composed of a figure indicating "!" (exclamation mark) is formed. Their uses will be described later.

[0363] The opposing plate portion 563 is formed such that the surface on the rotation axis side of the central portion is in an arc shape that forms part of the same circle with the surface constituent members 560a to 560d. A convex portion 563a is formed on one side (the front side of the surface constituent member 560a) of the front and rear ends, and a concave portion 563b is formed on the other side (the rear side of the surface constituent member 560a).

[0364] The concave portion 563b is formed in a shape that can be fitted with the convex portion 563a rotated 90 degrees about the left - right direction axis. For example, the convex portion 563a on the lower side of the surface constituent member 560b corresponding to a state where it is rotated 90 degrees about the left - right direction axis with respect to the surface constituent member 560a fits into the concave portion 563b on the left side of the surface constituent member 560a. At the same time, the concave portion 563b on the lower side of the surface constituent member 560b fits into the convex portion 563a on the left side of the surface constituent member 560a.

[0365] Note that as long as the above - mentioned conditions are satisfied, the shapes of the convex portion 563a and the concave portion 563b can be arbitrarily set. For example, it can be a shape with corners, a semi - circular shape, or an inclined shape. In the present embodiment, the convex portion 563a is configured to have a size capable of forming a female screw, so that the convex portion 563a is configured as a location where the fastening force of the fastening screw is exerted.

[0366] In a similar manner, by fitting the adjacent surface constituent members 560a to 560d, they can be aligned in a rectangular cylindrical shape. The left - right misalignment of the surface constituent members 560a to 560d is prevented by the left - right opposing portion 564.

[0367] That is, in a state where the surface constituent members 560a to 560d form a rectangular cylindrical shape, the left - right opposing portion 564 abuts (is oppositely arranged) against the concave portions 563b of the adjacent surface constituent members 560a to 560d from the inner side in the left - right direction.

[0368] For example, with respect to the left - right opposing portion 564 disposed on the front side of the surface - forming member 560a, the right - hand side surface that continues from the left - hand side (the outer side in the left - right direction of the rotating body 560) to the concave - shaped portion 563b disposed on the lower side of the surface - forming member 560d abuts (is oppositely disposed). That is, after an arrangement capable of forming a rectangular - cylinder shape is made, by displacing the surface - forming member 560d to the right with respect to the surface - forming member 560a, the left - right positions of the surface - forming member 560d with respect to the surface - forming member 560a can be aligned.

[0369] Also, with respect to the left - right opposing portion 564 disposed on the lower side (lower - right side) of the surface - forming member 560d, the left - hand side surface that continues from the right - hand side (the outer side in the left - right direction of the rotating body 560) to the concave - shaped portion 563b disposed on the front side of the surface - forming member 560a abuts (is oppositely disposed). That is, after an arrangement capable of forming a rectangular - cylinder shape is made, by displacing the surface - forming member 560d to the right with respect to the surface - forming member 560a, the left - right positions of the surface - forming member 560d with respect to the surface - forming member 560a can be aligned.

[0370] In this way, in the present embodiment, by making the shape of the symmetric protruding portion 562 rotationally symmetric with respect to the center point of the plate - shaped portion 561, with respect to one adjacent surface - forming member (for example, the surface - forming member 560a), by displacing the other surface - forming member (for example, the surface - forming member 560d) in one left - right direction, the left - right positions of the other surface - forming member with respect to one surface - forming member can be aligned.

[0371] The posture - aligning portion 566 is formed as posture - aligning portions 566a to 566d on each of the surface - forming members 560a to 560d, and is configured as through - holes having different shapes in each of the surface - forming members 560a to 560d.

[0372] That is, the alignment portion 566a formed on the surface component member 560a is bored with a circular cross-section, the alignment portion 566b formed on the surface component member 560b is bored with a rectangular shape that is short in the direction along the extending direction of the plate-like portion 561, the alignment portion 566c formed on the surface component member 560c is bored with a rectangular shape that is long in the direction along the extending direction of the plate-like portion 561, and the alignment portion 566d formed on the surface component member 560d is bored with an equilateral triangle cross-section.

[0373] The driven plate 555 includes a plurality of fitting convex portions 555a to 555d that project in shapes corresponding to the alignment portions 566a to 566d from positions where they can be inserted into the alignment portions 566a to 566d.

[0374] That is, a pair of fitting convex portions 555a project with a circular cross-section, a pair of fitting convex portions 555b project with a rectangular shape that is short in the direction along the adjacent side of the driven plate 555, a pair of fitting convex portions 555c project with a rectangular shape that is long in the direction along the adjacent side of the driven plate 555, and a pair of fitting convex portions 555d project with an equilateral triangle cross-section.

[0375] The driven plate 575 includes a plurality of fitting convex portions 575a to 575d that project in shapes corresponding to the alignment portions 566a to 566d from positions where they can be inserted into the alignment portions 566a to 566d.

[0376] That is, a pair of fitting convex portions 575a project with a circular cross-section, a pair of fitting convex portions 575b project with a rectangular shape that is short in the direction along the adjacent side of the driven plate 575, a pair of fitting convex portions 575c project with a rectangular shape that is long in the direction along the adjacent side of the driven plate 575, and a pair of fitting convex portions 575d project with an equilateral triangle cross-section.

[0377] In this way, by configuring the alignment portions 566a to 566d, the fitting convex portions 555a to 555d, and the fitting convex portions 575a to 575d in corresponding shapes, the rotating left lid portion 550, the rotating body 560, and the rotating right lid portion 570 can be fitted and fastened and fixed in a state where the relative angle is appropriate.

[0378] In actual assembly procedures, all four surface components 560a to 560d of the rotating body 560 are assembled, fitted into a rectangular cylindrical shape, and their left and right positions are aligned. Then, the fitting convex portions 555a to 555d of the left rotating lid portion 550 are fitted into the alignment portions 566a to 566d of the rotating body 560, and fastening screws inserted through the insertion holes formed at the four corners are screwed into the female screws of the convex-shaped portion 563a, thereby fastening and fixing the rotating body 560 and the left rotating lid portion 550. Next, by screwing in the fastening screws in the same procedure, the right rotating lid portion 570 can also be fastened and fixed to the rotating body 560.

[0379] In this embodiment, the fitting direction and the fastening and fixing direction of the left rotating lid portion 550 and the right rotating lid portion 570 with respect to the alignment portions 566a to 566d of the rotating body 560 are both designed to be in the left-right direction (the direction parallel to the rotation axis).

[0380] As a result, the fastening screws can be excluded from the outer surfaces (display surfaces) of the respective surface components 560a to 560d of the rotating body 560, so that it is possible to avoid the fastening screws being visually recognized on the display surface. In this case, a sealing member for hiding the fastening screws can be made unnecessary, and a decorative pattern can be formed using the entire area (total area) of the outer surfaces (display surfaces) of the respective surface components 560a to 560d. Therefore, the size (area, i.e., density) of the decorative pattern with respect to the size (area) of each of the components 560a to 560d can be increased.

[0381] Here, for example, even if one surface component (for example, the surface component 560a) is fastened and fixed to the left rotating lid portion 550 and then an attempt is made to assemble another surface component (for example, the surface component 560d), the fitting convex portion 555d of the left rotating lid portion 550 fastened and fixed to the one surface component 560a interferes with the opposing plate portion 563 of the other surface component 560d. Therefore, the concave-shaped portion 563b of the other surface component 560d cannot be slid into the space between the left and right opposing portions 564 of the one surface component 560a and the driven plate 555, and assembly cannot be performed.

[0382] Thus, in the present embodiment, the rotation left lid portion 550 and the rotation right lid portion 570 can be fastened and fixed only after all the surface component members 560a to 560d are combined into a rectangular cylindrical shape. Therefore, assembly errors (for example, assembling in a state where any of the surface component members 560a to 560d is missing) can be prevented.

[0383] That is, in the present embodiment, the fitting convex portions 555a to 555d and 575a to 575d can simultaneously achieve the effects of strengthening the rigidity of the rotation left lid portion 550, the rotating body 560, and the rotation right lid portion 570 by fitting, fitting the posture alignment portions 566a to 566d as fitting targets to assemble the rotation left lid portion 550, the rotating body 560, and the rotation right lid portion 570 in an appropriate posture, and preventing the omission of assembly of the surface component members 560a to 560d by limiting the assembly procedure.

[0384] FIGS. 29(a) and 29(b) are exploded front perspective views of the composite operation unit 402 of the first operation unit 400. In FIGS. 29(a) and 29(b), perspective views from different directions are shown, and the rotation unit 500 is arranged in a posture with the lower surface facing the front side.

[0385] The annular protrusion 412 is a protrusion having a C-shaped upper surface view with a dividing portion 412a (a cut) on the right side, and an overhanging shaped portion 516a corresponding to this dividing portion 412a is formed on the lower surface of the guide member 516.

[0386] In the assembled state (see FIG. 21), when the overhanging shaped portion 516a is arranged in the dividing portion 412a, the posture of the rotation unit 500 with respect to the support means 410 is defined. With the posture of the rotation unit 500 defined, a fastening screw inserted through the insertion hole 413a is screwed into a fastening portion 517a formed with a female screw, and thus the guide member 516 is fastened and fixed to the support means 410.

[0387] In the assembled state (see Fig. 21), the irregular holes 413 and 517 communicate as a passage for the electrical wiring DK1, but the internal shapes forming the outer frame of the passage are different. This difference in shape corresponds to a difference in the manner of the electrical wiring DK1 (see Fig. 21) guided from the irregular hole 413 or the irregular hole 517.

[0388] Specifically, the electrical wiring DK1 is vertically displaced as the support means 410 moves up and down below the irregular hole 413, while it is fixedly arranged above the irregular hole 517 (on the side of the rotating unit 500) regardless of the arrangement of the support means 410. Therefore, below the irregular hole 413, it is preferably configured in a manner that can easily correspond to vertical displacement, and above the irregular hole 517, it is preferably configured in a manner that can easily correspond to the path for fixing the electrical wiring DK1. Hereinafter, the manner of the electrical wiring DK1 of the present embodiment from this perspective will be described.

[0389] In the present embodiment, below the irregular hole 413, the electrical wiring DK1 composed of a bundle of a plurality of electric wires is bundled into a wire bundle close to a circular cross-section by being bundled into a member (so-called spiral tube) with a spiral cut in a tube-shaped member formed of a flexible resin material.

[0390] In the present embodiment, at least in the range of the electrical wiring DK1 that can enter (be accessible) the wiring auxiliary means 460, the spiral tube is wound.

[0391] By configuring the electrical wiring DK1 as a wire bundle close to a circular cross-section, regardless of the direction in which the electrical wiring DK1 bends as the support means 410 moves up and down, it is possible to configure it so that there is no significant difference in the resistance to the bending of the electrical wiring DK1 and the load applied due to the bending.

[0392] The irregular hole 413 has a shorter front-back width across the left-right direction compared to the shape of the irregular hole 517, so as to facilitate arranging the electrical wiring DK1 into a wire bundle with a cross-sectional shape close to circular. Thereby, while preventing each wire of the electrical wiring DK1 from being arranged so as to spread in the front-back direction, even when there are many wires, it is possible to easily arrange them so as to spread in the left-right direction. Therefore, when guiding the electrical wiring DK1 from the irregular hole 413 to the right and fixing it at the forming portion 411a with a fixing member such as a binding band, it is possible to easily form a wire bundle with a short front-back width and a substantially circular cross-section.

[0393] Note that the cross-sectional shape of the wire bundle of the electrical wiring DK1 does not need to be circular, and various modes are exemplified. For example, as the number of wires constituting the electrical wiring DK1 increases, the cross-section of the wire bundle tends to be an ellipse elongated in the left-right direction. Even in this case, compared to the case where the electrical wiring DK1 curves left and right, the resistance and load when curving in the front-back direction can be reduced. Curving in the front-back direction is an aspect of curving that is likely to occur in this embodiment, and details will be described later.

[0394] FIG. 30(a) is a front exploded perspective view of a partial configuration of the rotating unit 500, and FIG. 30(b) is a perspective view schematically showing a harness constituting the electrical wiring DK1. As shown in FIG. 30(b), the electrical wiring DK1 is configured such that a plurality of covered flexible wires are connected and fixed to a connector as a connection end portion at substantially equal intervals.

[0395] In the rotating unit 500 of this embodiment, connectors are respectively connected to the drive motor 541, the detection sensor 547, and the decorative substrate 543, and the total number of wires extending from each connector is 16.

[0396] In Fig. 30(a), among the rotating unit 500, a U-shaped metal plate 511, a right and left fixing cover 514 on the right side, a guiding member 516, both-end fixing means 520, a right main body portion 531 of the shaft, a left main body portion 535 of the shaft, a drive motor 541, a detection sensor 547, and a posture fixing bush 571 are shown. The right and left fixing cover 514 and the guiding member 516 are shown at intervals from the U-shaped metal plate 511, and only the right and left fixing cover 514 is shown in different directions of view.

[0397] In Fig. 30(a), mainly the guiding of the electrical wiring DK1 for the rotating unit 500 will be described. The electrical wiring DK1 passing upward through the irregular hole 517 is crawled into a gap with a long front-rear width and a short upper-lower width between the U-shaped metal plate 511 and the lowered bottom portion 518. Therefore, the electric wires constituting the electrical wiring DK1 are preferably arranged side by side in the front-rear direction instead of being stacked vertically.

[0398] On the other hand, in the present embodiment, the guiding member 516 is formed at the right end portion of the irregular hole 517 so as to be fan-shaped and step down from the lowered bottom portion 518 in a top view, and includes a fan-shaped adjusting portion 517b for adjusting the degree of spreading in the front-rear direction of a plurality of electric wires constituting the electrical wiring DK1. The function of this fan-shaped adjusting portion 517b will be described with reference to Fig. 31.

[0399] Fig. 31(a) is a top view of the guiding member 516, Fig. 31(b) is a cross-sectional view of the guiding member 516 and the electrical wiring DK1 along the line XXXIb-XXXIb of Fig. 31(a), Fig. 31(c) is a cross-sectional view of the guiding member 516 and the electrical wiring DK1 along the line XXXIc-XXXIc of Fig. 31(a), Fig. 31(d) is a cross-sectional view of the guiding member 516 along the line XXXId-XXXId of Fig. 31(a), and Fig. 31(e) is a cross-sectional view of the guiding member 516 and the electrical wiring DK1 along the line XXXIe-XXXIe of Fig. 31(d).

[0400] In FIGS. 31(a) and 31(d), a part of the path of each electric wire of the electrical wiring DK1 guided through the irregular hole 517 is schematically illustrated by imaginary lines, and in FIGS. 31(b), 31(c) and 31(e), an example of the arrangement of each electric wire of the electrical wiring DK1 is illustrated.

[0401] That is, each electric wire of the electrical wiring DK1 is curved so as to be closely arranged (abutted) to the lower corner part formed by the irregular hole 517 and the fan-shaped adjustment part 517b on two sides, and the upper corner part arranged on the right side of the lower corner part and formed by the lowering bottom part 518 and the fan-shaped adjustment part 517b on two sides. In this state, the dispersion (spread) in the front-rear direction is restricted by the front-rear wall parts of the fan-shaped adjustment part 517b (see FIGS. 31(a) and 31(c)).

[0402] In other words, by adjusting the formation angle of the front-rear wall parts of the fan-shaped adjustment part 517b, the degree of dispersion of the electrical wiring DK1 can be adjusted. From this viewpoint, in the present embodiment, the front-rear wall parts of the fan-shaped adjustment part 517b are configured such that the extension line 517x linearly extending from the end parts of the front-rear wall parts of the fan-shaped adjustment part 517b in a top view becomes a straight line reaching the corner part of the lowering bottom part 518.

[0403] Thereby, above the irregular hole 517, the degree of dispersion of the electrical wiring DK1 can be maximized while the electrical wiring DK1 is arranged in a single plane (the plane between the U-shaped metal plate 511 and the lowering bottom part 518). That is, near the right end part of the lowering bottom part 518, each electric wire of the electrical wiring DK1 can be easily arranged in a dispersed manner by the front-rear width of the lowering bottom part 518 (see FIG. 31(b)).

[0404] In the present embodiment, the fan-shaped adjustment part 517b is designed such that the front-rear interval at the left end part is about 6.4 [mm], and the inclination angle of the front-rear inclined walls with respect to the left-right direction is 35 degrees (central angle 70 degrees).

[0405] As shown in Fig. 31(b), in the range from the right end of the lowering bottom portion 518 to the central portion of the fastening portion 516b, each electric wire of the electrical wiring DK1 can be arranged in a state where the electric wires are in contact with the bottom surface of the lowering bottom portion 518, rather than being vertically folded. That is, the front-back width (about 15.4 [mm] in this embodiment) of a dimension (about 11.2 [mm] for 16 wires in this embodiment) or more necessary for arranging the electric wires with an outer diameter (about 0.7 [mm] in this embodiment) side by side on the same plane is ensured.

[0406] Thereby, even if the depth of the lowering bottom portion 518 (the gap dimension with the lower surface of the U-shaped metal plate 511) is designed to be small (about 2 [mm] in this embodiment), it is easy to prevent a compressive load from being applied to the electrical wiring DK1 from the constituent members assembled around the electrical wiring DK1.

[0407] Note that various aspects are exemplified for the shape of the fan-shaped adjustment portion 517b. For example, when the front-back width is larger compared to the shape of this embodiment, each electric wire of the electrical wiring DK1 can be spread over the front-back width of the lowering bottom portion 518 from near the left and right central portions of the lowering bottom portion 518, and the width of the passage path of the electric wires can be widened. Thus, even when the number of electric wires is large, there is an advantage that the load applied to the electric wires from the fan-shaped adjustment portion 517b can be reduced. On the other hand, there is also a drawback that the electric wires may be curved (bent) in the plane between the front and rear wall portions of the guide member 516 before reaching the right end of the lowering bottom portion 518.

[0408] Also, for example, when the front-back width is smaller compared to the shape of this embodiment, there is an advantage that the possibility of the electric wires being curved (bent) in the plane between the U-shaped metal plate 511 and the lowering bottom portion 518 can be reduced. On the other hand, there is also a drawback that since the width of the passage path of the electric wires becomes narrow, the load applied to the electric wires from the fan-shaped adjustment portion 517b tends to increase when the number of electric wires is large.

[0409] Therefore, the shape of the fan-shaped adjustment part 517b in the present embodiment is a preferable shape in that it can reduce the possibility of the electric wire bending (buckling) in the plane between the U-shaped metal plate 511 and the lowering bottom part 518 (the advantage that the electric wiring DK1 can reach the right end part of the lowering bottom part 518 along the horizontal straight line), and can ensure the maximum width of the passing path of the electric wire.

[0410] Also, the extension line 517x serves as a guide for the arrangement range of each electric wire of the electric wiring DK1, mainly as a guide for the outer edge of the arrangement, and is configured to intersect to the right of the center of the irregular hole 517. In other words, the extension line 517x intersects to the right of the straight line connecting the centers of the pair of upper and lower fastening parts 517a.

[0411] Thereby, the position where each electric wire of the electric wiring DK1 gathers can be arranged to the right of the center of the irregular hole 517 on the lower side of the irregular hole 517 (see Fig. 31(e)). Therefore, as schematically shown in Fig. 31(d), even when the electric wiring DK1 passes only through the range to the right of the irregular hole 517 in relation to the arrangement of the forming part 411a, each electric wire can guide the electric wiring DK1 to the forming part 411a (see Fig. 23) in a sufficiently gathered state.

[0412] In this way, the irregular hole 517 is formed in a shape that can assist the change when the degree (state) of dispersion of the electric wiring DK1 changes before and after passing through. Therefore, compared with the case where the degree (state) of dispersion of each electric wire of the electric wiring DK1 changes suddenly, the possibility of each electric wire bending can be reduced, and the load applied to the electric wiring DK1 can be reduced.

[0413] The guide member 516 includes a plurality of fastening parts 516b composed of positioning pins used for fastening to the U-shaped metal plate 511 and insertion holes for fastening screws fastened to the U-shaped metal plate 511.

[0414] Since the fastening part 516b is also arranged at the lowering bottom part 518 where the electrical wiring DK1 is arranged, the arrangement area of the electrical wiring DK1 is somewhat restricted. However, in this embodiment, the arrangement is devised to minimize this restriction.

[0415] First, a plurality of fastening parts 516b are arranged on the opposite side (left side) of the lowering bottom part 518 as a position that does not interfere with the electrical wiring DK1, and by securing the fastening force, the number of fastening parts 516b arranged at the lowering bottom part 518 is minimized.

[0416] Note that the fastening part 516b may not be arranged at the lowering bottom part 518. However, in that case, due to the weight of the electrical wiring DK1 fixed to the downward extension part 519, or the vibration and load generated when the rotating unit 500 moves up and down, there is a possibility that the U-shaped metal plate 511 and the lowering bottom part 518 may be displaced. To avoid this, the guide member 516 may be configured to have a thick wall. However, in that case, the thickness of the guide member 516 in the front view becomes large, and it becomes difficult to make the rotating body 560 conspicuous, resulting in a disadvantage in terms of the appearance effect.

[0417] That is, in this embodiment, by arranging the fastening part 516b in the minimum number at the lowering bottom part 518, it is possible to achieve the effect of enhancing the presence of the rotating body 560 in the front view by configuring the guide member 516 to be thin while maintaining the effect of securing the arrangement width of the electrical wiring DK1.

[0418] Also, by making the remaining fastening part 516b the fastening part 516b on the side far from the right end of the lowering bottom part 518, it is possible to minimize the degree to which the arrangement width of the electrical wiring DK1 is reduced.

[0419] The fastening portion 516b disposed at the lowering bottom portion 518 is provided with a positioning pin 516c in the same manner as the fastening portion 516b disposed on the left side of the guide member 516 (see Fig. 30(a)). The positioning pin 516c is disposed at a position where the arrangement of the electrical wiring DK1 has already been made impossible by the fastening portion 516b. That is, it is disposed on a straight line drawn from the irregular hole 517 and overlapping the fastening portion 516b, and at a position on the opposite side of the irregular hole 517 with respect to the fastening portion 516b.

[0420] Thereby, it is possible to avoid the positioning pin 516c from narrowing the arrangement range (arrangement width) of the electrical wiring DK1. Therefore, while ensuring the ease of arrangement when assembling the guide member 516 to the U-shaped metal plate 511 by the positioning pin 516c, the wiring range (arrangement width) of the electrical wiring DK1 can be ensured.

[0421] Returning to Fig. 30(a) for explanation. The electrical wiring DK1 that has reached the right end portion of the lowering bottom portion 518 curves upward along the left plate surface of the left and right fixing covers 514, and then is disposed between the U-shaped metal plate 511 and the left and right fixing covers 514.

[0422] The left and right fixing covers 514 mainly include a main body plate portion 514a formed in a flat plate shape, an extended frame portion 514b extending to a position facing the front, rear, upper, and lower surfaces of the U-shaped metal plate 511 along the outer shape of the main body plate portion 514a, a space securing portion 514c formed to fill the corner portion formed by the extended frame portion 514b and the main body plate portion 514a and recessed toward the main body plate portion 514a side from the extended frame portion 514b, a fastening portion 514d formed in a part of the space securing portion 514c and composed of a positioning pin used for fastening to the U-shaped metal plate 511 and an insertion hole for a fastening screw fastened to the U-shaped metal plate 511, and jig holes 514e formed in the main body plate portion 514a at the front and rear positions of the fastening portion 514b.

[0423] The space securing portion 514c is formed at a position in contact with the U-shaped metal plate 511 in the left and right directions. Thereby, the electrical wiring DK1 crawls into the gap corresponding to the thickness of the space securing portion 514c generated between the U-shaped metal plate 511 and the main body plate portion 514a.

[0424] The fastening part 514d is disposed on the front side, similarly to the fastening part 516b disposed on the lowering bottom part 518. Thereby, a range in which the electric wiring DK1 is disposed can be secured to the rear side continuously from the lowering bottom part 518 to the left and right fixing covers 514.

[0425] Here, by disposing the fastening parts 514d and 516b on the front side, the degree of reduction in the production performance with respect to the loosening of the fastening screw can be lowered. For example, when the fastening parts 514d and 516b are disposed on the rear side, when the fastening screw is loosened, the displacement with respect to the U-shaped metal plate 511 becomes large in the front side part which is easily visible to the player, so there is a risk of causing a reduction in the production performance.

[0426] On the other hand, when the fastening screws of the fastening parts 514d and 516b disposed on the front side are loosened, the part where the displacement with respect to the U-shaped metal plate 511 becomes large is the rear side part where the fastening screw is not disposed, but since the rear side part is a part that is difficult to be visually recognized by the player, it is difficult for the player to notice the loosening of the fastening screw. Therefore, the degree of reduction in the production performance can be lowered.

[0427] Further, since the positioning pins of the fastening part 514d are disposed overlapping the upper and lower sides (the longitudinal direction of the electric wiring DK1) of the insertion hole, the degree to which the insertion hole and the positioning pins narrow the disposed range of the electric wiring DK1 can be minimized.

[0428] The jig hole 514e is an opening for inserting a jig (not shown) for adjusting the arrangement of the electric wiring DK1 from the outside in order to avoid the electric wiring DK1 being pinched (crushed) between the U-shaped metal plate 511 and the space securing part 514c when assembling the left and right fixing covers 514 to the U-shaped metal plate 511.

[0429] From this perspective, the jig hole 514e becomes unnecessary after the assembly work. On the other hand, in the present embodiment, since the jig hole 514e is formed at a left - right position where it is difficult for the player to visually recognize it, it is possible to prevent the production effect from being reduced due to the jig hole 514e being visually recognized by the player.

[0430] The electrical wiring DK1 disposed between the U - shaped metal plate 511 and the left - right fixing covers 514 passes through the inner diameter side of the right fixing bush 522 of the both - ends fixing means 520 and is disposed inside the U - shaped metal plate 511. Each electric wire of the electrical wiring DK1 disposed inside the U - shaped metal plate 511 is connected to the drive motor 541, the decorative substrate 543, and the detection sensor 547, enabling power supply.

[0431] Here, the electrical wiring DK1 not only passes through the inside of the right fixing bush 522 but also passes through the inside of the right - hand shaft main body part 531, the left - hand shaft main body part 535, and the posture fixing bush 571. Thereby, it is possible to physically prevent the electrical wiring DK1 from coming into contact with the rotating parts of the rotating unit 500 (the rotating body 560, the rotating left plate 550, the motor gear 542 meshed with the rotating left plate 550, and the driven plate 575 of the rotating right cover part 570).

[0432] Also, the electrical wiring DK1 passes through the inside of the right - hand shaft main body part 531 disposed on the right side, which is the opposite side of the left - hand shaft main body part 535 where the drive motor 541 is fastened and fixed, and is disposed inside the U - shaped metal plate 511. It is disposed at a position on the opposite side of the drive motor 541 with respect to the protruding fastening part 537, that is, between the protruding fastening part 537 and the arc - shaped extending part 535a extending rightward along the outer shape of the left - hand shaft main body part 535.

[0433] As a result, the electrical wiring DK1 can be arranged away from the drive motor 541, so that it is possible to avoid the electrical wiring DK1 from being damaged due to high temperature caused by the heat generated from the drive motor 541. Further, this effect is caused by the routing of the electrical wiring DK1 around the protruding fastening portion 537 as the fastening portion, and can be achieved without adding a separate dedicated member for arranging the electrical wiring DK1 away from the drive motor 541, so that the product cost can be reduced.

[0434] With reference to FIGS. 32 to 34, the vertical movement of the composite operation unit 402 of the first operation unit 400 will be described. In FIGS. 32 to 34, the first operation unit 400 that moves vertically is illustrated in time series. That is, in FIG. 32, a state where the rotation unit 500 is disposed at the lowered position is illustrated, in FIG. 33, a state where the rotation unit 500 is disposed at the intermediate position of the vertical movement range is illustrated, and in FIG. 34, a state where the rotation unit 500 is disposed at the raised position is illustrated.

[0435] FIG. 32(a) is a left side view of the composite operation unit 402, FIG. 32(b) is a front view of the composite operation unit 402, and FIG. 32(c) is a right side view of the composite operation unit 402. In FIG. 32(a), for ease of understanding, the back side is illustrated through the metal plate portion 432, and the outer shape of the metal plate portion 432 is illustrated by an imaginary line. In FIG. 32(c), the illustration of the right side member 468 is omitted.

[0436] Further, FIG. 33(a) is a left side view of the composite operation unit 402, FIG. 33(b) is a front view of the composite operation unit 402, and FIG. 33(c) is a right side view of the composite operation unit 402. In FIG. 33(a), for ease of understanding, the back side is illustrated through the metal plate portion 432, and the outer shape of the metal plate portion 432 is illustrated by an imaginary line. In FIG. 33(c), the illustration of the right side member 468 is omitted.

[0437] Further, FIG. 34(a) is a left side view of the composite operation unit 402, FIG. 34(b) is a front view of the composite operation unit 402, and FIG. 34(c) is a right side view of the composite operation unit 402. In FIG. 34(a), for ease of understanding, the back side is shown through the metal plate portion 432, and the outer shape of the metal plate portion 432 is shown by an imaginary line. In FIG. 34(c), the illustration of the right side member 468 is omitted.

[0438] First, with reference to FIGS. 32(a), 33(a) and 34(a), the operation of the transmission means 450 by the drive means 440 will be described. As the drive shaft of the drive motor 441 of the drive means 440 rotates, when the drive gear 441a rotates, the transmission gear 451 meshed with the drive gear 441a, the intermediate gear 452 meshed with the transmission gear 451, and the rotating arm member 453 with the gear portion 453a meshed with the intermediate gear 452 all rotate simultaneously.

[0439] When the drive gear 441a is rotated clockwise in a left side view from the state shown in FIG. 32(a), the rotating arm member 453 rotates counterclockwise in a left side view and stops at a position where it contacts the rotation restricting portion 442f extending leftward from the upper end portion of the partition plate portion 442a of the divided base member 442 as shown in FIG. 34(a).

[0440] Conversely, when the drive gear 441a is rotated counterclockwise in a left side view from the state shown in FIG. 34(a), the rotating arm member 453 rotates clockwise in a left side view. As shown in FIG. 32(a), when the detected plate portion 453d is inserted into the detection sensor 442d, it is detected that the rotating arm member 453 is arranged at the rotation end position (see FIG. 32(a)), and the drive of the drive motor 441 is stopped and controlled.

[0441] Note that at the end position of this operation, the connecting member 454 connected to the rotating tip of the rotating arm member 453 abuts against the inner wall of the through long hole 416a of the support means 410 in the left - right direction (a direction perpendicular to the direction in which the displacement of the support means 410 is allowed), thereby restricting the rotation of the rotating arm member 453. Therefore, an additional abutting portion (for example, a portion corresponding to the rotation restricting portion 442f) is not provided intentionally.

[0442] As shown in FIGS. 32(a), 33(a), and 34(a), the detected plate portion 453d is formed in an arc shape centered on the rotation axis of the rotating arm member 453. The detection sensor 442d is in a posture where the detection groove overlaps with the arc, and the proximal - end side portion of the detection groove is arranged radially outside the arc.

[0443] Thereby, the detected plate portion 453d can be detected by the detection sensor 442d, and even when the rotating arm member 453 rotates beyond the rotation end position (the position in FIG. 32(a)), it is possible to avoid the detected plate portion 453d from colliding with the proximal - end side portion of the detection groove of the detection sensor 442d.

[0444] As shown in FIG. 34(a), at the rising position of the rotating unit 500, since the fastening screw insertion hole of the end plate member 421 is arranged inside the notch portion of the metal plate portion 432, the fastening screw can be turned with a driver.

[0445] That is, at the time of assembly, by arranging the rotating unit 500 at the rising position, the operation of fixing the stacking means 420 and the support means 410 can be performed. At the time of maintenance, by arranging the rotating unit 500 at the rising position, the operation of releasing the fixing of the stacking means 420 and the support means 410 can be performed.

[0446] The assembly order of the composite operation unit 402 of the first operation unit 400 and the rotating unit 500 will be described. In the description of the assembly order, FIGS. 23, 24, 25, 26, 30(a), and 31 will be referred to as appropriate.

[0447] First, assemble from the rotating unit 500. At this time, while connecting one end of the electrical wiring DK1 corresponding to the drive motor 541, the decorative substrate 543, and the detection sensor 547, assemble and integrate each component of the shaft configuration means 530. At this time, the other end side of the electrical wiring DK1 is led outside through the wiring opening 533b (see FIGS. 25 and 30(a)).

[0448] Next, assemble and integrate the rotating left lid portion 550, the rotating body 560, and the rotating right lid portion 570 with respect to the shaft configuration means 530. At this time, the other end side of the electrical wiring DK1 is led outside through the opening at the center of the posture fixing bush 571 (see FIGS. 25 and 30(a)).

[0449] In a state where the rotating left lid portion 550, the rotating body 560, and the rotating right lid portion 570 are integrated, the distance between the left surface of the geared flange 551 and the right surface of the posture fixing bush 571 is configured to be slightly shorter than the distance between the plate portions that are arranged to face each other as the tip portions of the U-shaped metal plate 511.

[0450] Therefore, the assembly in which the rotating left lid portion 550, the rotating body 560, and the rotating right lid portion 570 are integrated can be arranged between the plate portions that are arranged to face each other as the tip portions of the U-shaped metal plate 511. At this time, the protruding fastening portion 532 is arranged in alignment with the position of the circular hole 513a.

[0451] Next, fit the both-end fixing means 520 from the left and right outer sides of the U-shaped metal plate 511. At this time, the other end side of the electrical wiring DK1 is led outside through the central opening of the right fixing bush 522 (see FIG. 30(a)).

[0452] The shapes of the both-end fixing means 520 and the U-shaped metal plate 511 are configured to be able to restrict the rotation of the both-end fixing means 520 with respect to the U-shaped metal plate 511 (for example, concave-convex fitting), and the shapes of the both-end fixing means 520 and the shaft configuration means 530 are configured to be able to restrict the rotation of the shaft configuration means 530 with respect to the both-end fixing means 520 (for example, fitting with a D-shaped cross section). Therefore, the rotation of the shaft configuration means 530 with respect to the U-shaped metal plate 511 can be restricted (see FIG. 25).

[0453] Insert a fastening screw through the insertion hole 523 and thread the fastening screw into the protruding fastening portion 532, thereby fastening and fixing the shaft forming means 530 to the U-shaped metal plate 511. As a result, the U-shaped metal plate 511, the both-end fixing means 520, the shaft forming means 530, the rotating left lid portion 550, the rotating body 560, and the rotating right lid portion 570 can be integrated. Note that, among the both-end fixing means 520, the left fixing bush 521 is prevented from coming off by the left and right fixing lids 514, and the arrangement of the fastening screws is omitted.

[0454] Next, fasten and fix the left and right fixing lids 514 and the guide member 516 to the U-shaped metal plate 511. At this time, the other end side of the electrical wiring DK1 is passed through the deformed hole 517 of the guide member 516 and led downward (see Fig. 30(a)).

[0455] In order to narrow the gap between the U-shaped metal plate 511 and the left and right fixing lids 514, it is preferable to arrange the plurality of electric wires constituting the electrical wiring DK1 between the U-shaped metal plate 511 and the left and right fixing lids 514 in a dispersed manner in the front-rear direction (see Fig. 31(b)).

[0456] In the assembling operation of this embodiment, a dedicated jig (rod-shaped, string-shaped, or a jig with a dedicated special shape) is inserted through the jig hole 514e, so that the left and right fixing lids 514 can be assembled to the U-shaped metal plate 511 while adjusting the arrangement of the electrical wiring DK1. As a result, the difficulty of the step of assembling while dispersing the plurality of electric wires constituting the electrical wiring DK1 can be reduced.

[0457] When fastening and fixing the guide member 516 to the U-shaped metal plate 511, the guide member 516 is assembled to the U-shaped metal plate 511 while pulling the electrical wiring DK1 downward, so that the electrical wiring DK1 is naturally drawn into the inside of the fan-shaped adjusting portion 517b (see Fig. 31(c)). As a result, the difficulty of the step of assembling while arranging the electrical wiring DK1 at an appropriate position can be reduced.

[0458] When assembling the rotation unit 500 integrally assembled by the above procedure to the support means 410, it should be noted that the other end side of the electrical wiring DK1 is passed downward through the irregular hole 413. A spiral tube is wound around the electrical wiring DK1 that has emerged below the irregular hole 413.

[0459] Among the composite operation units 402 of the first operation unit 400, the configuration excluding the wiring assisting means 460 can be assembled separately from the rotation unit 500. Therefore, it is integrally assembled before assembling the rotation unit 500. After fixing the rotation unit 500 to the support means 410 in that state, the other end side of the electrical wiring DK1 is fixedly arranged.

[0460] That is, the electrical wiring DK1 is fixed by a fixing member such as a binding band inserted through the forming portion 411a of the support means 410, fixed to the downward extending portion 519 of the guide member 516 in the same manner, passed under the support column portion 464 of the wiring assisting means 460, and fixed by a fixing member such as a binding band inserted through the wiring support portion 465, and passed to the back side through the opening 442e of the divided base member 442 (see FIG. 23).

[0461] With the electrical wiring DK1 passed through the opening 442e, by fastening and fixing the left member 461 to the divided base member 442, the electrical wiring DK1 can be arranged in the gap between the partition plate portion 442a and the left member 461. According to this assembling method, compared with the case where the arrangement of the electrical wiring DK1 is determined with the left member 461 fixed to the divided base member 442, the electrical wiring DK1 can be arranged in a gap narrower than the size of the connector at the tip of the electrical wiring DK1. Therefore, the gap between the partition plate portion 442a and the left member 461 can be designed to be narrow.

[0462] After that, by fastening and fixing the right member 468 to the left member 461, the assembly of the composite operation unit 402 of the first operation unit 400 can be completed. Thus, according to this embodiment in which the wiring auxiliary means 460 is not formed as an integral body but is separately formed by the left member 461 and the right member 468, the workability of the work of arranging the electrical wiring DK1 inside the wiring auxiliary means 460 can be improved.

[0463] Next, with reference to FIGS. 32(b), 32(c), 33(b), 33(c), 34(b) and 34(c), the relationship between the wiring auxiliary means 460, the electrical wiring DK1, the support means 410 for supporting the electrical wiring DK1, and the guide member 516 will be described.

[0464] As shown in FIG. 32(b), at the lowered position of the rotating unit 500, the front vertical portion 414 of the support means 410 abuts against and is supported by the upper end portion of the left member 461 of the wiring auxiliary means 460. That is, the wiring auxiliary means 460 also functions as means for supporting the rotating unit 500.

[0465] In other words, while adopting a configuration in which only the left side portion of the rotating unit 500 is supported by the stacking means 420 and the guiding means 430 (see FIG. 23), the rotating unit 500 can be supported on both the left and right sides as long as the rotating unit 500 is disposed at the lowered position.

[0466] Thereby, the upper limit value of the rotational speed of the rotating body 560 in a state where the wobbling of the rotating unit 500 is within an allowable range can be increased in a state where the rotating unit 500 is disposed at the lowered position as compared with other states (for example, a state where the rotating unit 500 is disposed at the raised position).

[0467] As shown in FIG. 32(c), at the descending position of the rotating unit 500, the lower end of the front vertical portion 414 abuts against the front upper end of the strip-shaped extending portion 463 of the wiring assisting means 460. Thereby, the opening above the wiring assisting means 460 can be shielded from the player's line of sight (the downward oblique view). Thus, in a state where the rotating unit 500 is disposed at the descending position, it is possible to avoid the electrical wiring DK1 accommodated in the wiring assisting means 460 from being seen by the player.

[0468] The electrical wiring DK1 is fixed by a fixing member such as a binding band to the forming portion 411a (see FIG. 23), fixed by a fixing member such as a binding band to the lower end of the downward extending portion 519 below it, and the hanging portion below it is supported (accommodated) inside the wiring assisting means 460.

[0469] The length of the electrical wiring DK1 (see FIG. 32(c)) accommodated inside the wiring assisting means 460 is designed to be such a length that the portion disposed between the strip-shaped extending portion 463 and the support pillar portion 464 floats in a state where the rotating unit 500 is disposed at the ascending position (see FIG. 34(c)).

[0470] Also, the shape of the strip-shaped extending portion 463 is designed to be such a length that the electrical wiring DK1 disposed substantially in an arc shape on the front side of the functional curved surface 463a reaches the downward extending portion 519 without excessive slack (see FIG. 32(a)).

[0471] In this way, by designing the electrical wiring DK1 to have a sufficient length so as not to impose a burden on the electrical wiring DK1, the electrical wiring DK1 can be disposed inside the wiring assisting means 460 with a margin. Also, since the electrical wiring DK1 reaches the downward extending portion 519 without excessive slack, it is possible to prevent a situation where the electrical wiring DK1 is pinched between the strip-shaped extending portion 463 and the front vertical portion 414.

[0472] The spiral tube (not shown) wound around the electrical wiring DK1 is formed of a flexible silicone resin, but due to its shape, it is slightly more rigid than the electrical wiring. Therefore, variations in the displacement of the electrical wiring DK1 accompanying the vertical movement of the rotating unit 500 can be suppressed.

[0473] Also, since the electrical wiring DK1 can be supported by the rigidity of the spiral tube (the electrical wiring DK1 can be supported from below by the spiral tube), even when the electrical wiring DK1 is suspended by the wiring support portion 465 and the downward extending portion 519, it is possible to prevent the electrical wiring DK1 from sagging under its own weight, so that the arrangement of the electrical wiring DK1 can be stabilized.

[0474] The electrical wiring DK1 supported inside the wiring auxiliary means 460 is fixed to the wiring support portion 465 by a fixing member such as a binding band, and is guided rearward through the opening 442e through between the left member 461 and the partition plate portion 442a (see FIG. 23). That is, in the present embodiment, the electrical wiring DK1 is supported and suspended by the downward extending portion 519 and the wiring support portion 465.

[0475] Inside the downward extending portion 519 and the wiring support portion 465, the wiring support portion 465 is fixed, and the downward extending portion 519 is configured to be vertically movable. Since the arrangement of the electrical wiring DK1 is more likely to vary on the side of the downward extending portion 519 (front side), the space above the strip-shaped extending portion 463 can be secured larger on the side of the downward extending portion 519 (front side).

[0476] Specifically, by configuring the shape on the front side to be lowered downward compared to the shape on the back side and to have an arc shape centered inside (above) the wiring auxiliary means 460, a large space in which the electrical wiring DK1 can be arranged is secured.

[0477] As shown in FIG. 33(b), the rotating arm member 453 is arranged on the left side of the composite operation unit 402, and the electrical wiring DK1 is arranged on the right side of the composite operation unit 402, and their respective arrangement ranges are partitioned by the partition plate portion 442a.

[0478] Here, the partition plate portion 442a is an essential configuration as a portion for supporting the drive motor 441 and the transmission means 450. That is, without adding a dedicated member, the arrangement ranges of the rotating arm member 453 and the electrical wiring DK1 can be divided, so that while reducing the material cost, interference between the rotating arm member 453 and the electrical wiring DK1 can be avoided.

[0479] As shown in FIG. 34(c), at the raised position of the rotating unit 500, since the extending direction of the extending arm portion 453b of the rotating arm member 453 is the vertical direction starting from the rotation axis, it intersects at a right angle in the left-right direction view with respect to the longitudinal direction (front-rear direction) of the through long hole 416a. In other words, the straight line connecting the rotation axis of the rotating arm member 453 and the center of the connecting member 454 is in the vertical direction and intersects at a right angle in the left-right direction view with respect to the longitudinal direction (front-rear direction) of the through long hole 416a.

[0480] Thereby, the self-weight of the rotating unit 500 heads toward the rotation axis of the rotating arm member 453, and it is possible to prevent the self-weight from being loaded in the rotation direction of the rotating arm member 453 (so-called, the effect of the dead point occurs). Therefore, even if the driving force of the drive motor 441 is released in a state where the rotating unit 500 is arranged at the raised position, the vertical position of the rotating unit 500 can be maintained. Thereby, the driving time of the drive motor 441 can be reduced, and its heat generation can be easily suppressed.

[0481] It should be noted that the fact that the extending direction of the extending arm portion 453b of the rotating arm member 453 and the through long hole 416a intersect at a right angle in the left-right direction view is the same even in a state where the rotating unit 500 is arranged at the lowered position (see FIG. 32(a)).

[0482] As a result, when the rotational unit 500 bounces (rebounds) after being placed in the lowered position, the upward load will act toward the rotation axis of the rotation arm member 453, preventing the load from being applied in the rotational direction of the rotation arm member 453 (i.e., the so-called dead point effect occurs). Therefore, even when the rotational unit 500 is rapidly moved to the lowered position, it is easier to prevent bounce displacement (rebound displacement) from occurring.

[0483] Accordingly, it is possible to partially eliminate the need for the drive motor 441 to generate a load for preventing bounce displacement (rebound displacement). Thus, the drive time of the drive motor 441 can be reduced, and its heat generation can be more easily suppressed.

[0484] As shown in FIG. 34(c), in a state where the rotational unit 500 is placed in the raised position, the connecting member 454 of the rotation arm member 453 is disposed at the rear end of the through elongated hole 416a, i.e., at a position overlapping the rear columnar member 431 in the left-right direction. Therefore, the supporting force transmitted through the rotation arm member 453 is concentrated on the rear side of the supporting means 410, and the front side portions of the supporting means 410 and the rotational unit 500 are likely to wobble.

[0485] In contrast, in the present embodiment, the front columnar member 431 is configured to support the stacking means 420 via the guide cylindrical portion 423 (see FIG. 23). Thereby, the area (surface area) of the stacking means 420 supported by the columnar member 431 can be increased, so that wobbling of the front side portions of the stacking means 420, the supporting means 410, and the rotational unit 500 can be suppressed.

[0486] The displacement of the electrical wiring DK1 when the rotational unit 500 moves from the raised position toward the lowered position will be described. As shown in FIG. 34(c), the electrical wiring DK1 is guided upward from below the support column portion 464 through the front side and fixed to the downward extension portion 519.

[0487] Since the downward extending portion 519 is arranged on the front side of the support column portion 464 as shown in Fig. 34(c), the portion (extra portion) hanging down from the downward extending portion 519 of the electrical wiring DK1 is arranged on the front side of the support column portion 464.

[0488] This extra portion of the electrical wiring DK1 is displaced vertically as the downward extending portion 519 moves up and down. For example, when the downward extending portion 519 moves downward from the state shown in Fig. 34(c), the extra portion of the electrical wiring DK1 also moves downward accordingly and begins to contact the functional curved surface 463a of the strip-shaped extending portion 463 (see Fig. 33(c)).

[0489] As the downward extending portion 519 approaches the arrangement at the lowered position of the rotating unit 500, the length of the electrical wiring DK1 accommodated in the wiring assisting means 460 increases, and the diameter of the arc formed by the electrical wiring DK1 becomes larger.

[0490] In this embodiment, the electrical wiring DK1 will be displaced toward the front side due to the load received from the functional curved surface 463a. As a countermeasure, the upper region of the strip-shaped extending portion 463 is configured to be larger on the front side than on the back side, so that the load applied to the electrical wiring DK1 from the strip-shaped extending portion 463 can be reduced.

[0491] Also, while moving the electrical wiring DK1 near the functional curved surface 463a (the electrical wiring DK1 near the bottom of the wiring assisting means 460) where a load is applied due to the contact between the electrical wiring DK1 and the functional curved surface 463a toward the front side, before contacting the functional curved surface 463a, the electrical wiring DK1 is configured to hang down from the downward extending portion 519 arranged at a position far from the front-side end of the wiring assisting means 460, so that it is possible to prevent the electrical wiring DK1 from protruding toward the front side from the front-side end of the wiring assisting means 460.

[0492] Thus, while adopting a configuration in which the front vertical portion 414 and the wiring auxiliary means 460 come into contact with each other (partially closing the opening of the wiring auxiliary means 460) in a state where the rotating unit 500 is disposed at the lowered position as in the present embodiment (see FIG. 32(c)), it is possible to avoid the electrical wiring DK1 being pinched at the contact portion (closed portion).

[0493] As described above, in the present embodiment, since the shape of the functional curved portion 463a is configured as an inclined surface that slopes downward toward the front side, it is possible to make the main displacement direction of the electrical wiring DK1 be in the front-rear direction. As a result, the width in the left-right direction where displacement is less likely to occur in the electrical wiring DK1 is short (narrow), and an appropriate shape of the wiring auxiliary means 460 can be selected from a shape where the width in the front-rear direction where displacement is likely to occur in the electrical wiring DK1 is long (wide).

[0494] By partially restricting the displacement direction of the electrical wiring DK1 and enabling selection of a shape with a narrow left-right width as the shape of the wiring auxiliary means 460, the left-right width of the composite operation unit 402 can be suppressed.

[0495] Therefore, even in a configuration in which a plurality of composite operation units 402 are arranged side by side (see FIG. 19) as in the present embodiment, it is possible to avoid a situation where the shape of the wiring auxiliary means 460 having an auxiliary role of accommodating the electrical wiring DK1 becomes a limitation, and the degree of freedom in arranging the rotating unit 500 having a main role visually recognized by the player as an effect device is reduced.

[0496] Regarding the displacement of the electrical wiring DK1 in the left-right direction, first, by securing a gap between the left and right upper ends of the wiring auxiliary means 460 and the support means 410 (see FIG. 32(c)), it is possible to avoid applying a pinching load to the electrical wiring DK1.

[0497] Second, the opposing plate 462 has an inclined portion 462a that inclines upward at its upper end in a direction away from the right member 468, and the right member 468 has an inclined portion 468a that inclines upward at its upper end in a direction away from the opposing plate 462, so that the electrical wiring DK1 can easily slide into the wiring auxiliary means 460.

[0498] That is, the inclined portions 462a and 468a are configured in an inverted V shape in a front view in which the opening width increases as it approaches the side that receives the electrical wiring DK1. Therefore, even if the electrical wiring DK1 is displaced in either the left or right direction, the electrical wiring DK1 can be easily guided into the wiring auxiliary means 460. As a result, it is possible to easily avoid a situation where the electrical wiring DK1 catches on the upper edge of the wiring auxiliary means 460, is not guided by the wiring auxiliary means 460, and is sandwiched between the support means 410 and the wiring auxiliary means 460.

[0499] Third, the left and right positions of the wiring support portion 465 and the downward extending portion 519 that fix and suspend the electrical wiring DK1 are designed to match (see FIGS. 33(b) and 34(b)). That is, by arranging the position where the electrical wiring DK1 is fixed on the same plane orthogonal to the left and right directions, it is possible to suppress the lateral displacement of the electrical wiring DK1 accompanying the vertical displacement of the rotary unit 500.

[0500] Referring to FIG. 35, an example of an operation effect using the first operation unit 400 will be described. FIGS. 35(a), 35(b), 35(c), 35(d), 35(e), and 35(f) are front views of the third symbol display device 81 and the first operation unit 400 schematically showing the third symbol display device 81 and the first operation unit 400.

[0501] In FIGS. 35(a), 35(b), 35(c), and 35(d), an example of the change of the first operation unit 400 during the game is illustrated in time series, and in FIGS. 35(e) and 35(f), an example of an effect of performing notifications of different contents by the interlocking of a plurality of rotary units 500 is illustrated.

[0502] In this embodiment, the lighting or extinguishing of the rotating unit 500 is controlled to correspond to the number of balls on hold that fluctuates with the ball entry into the first winning opening 64 (or the second winning opening 640, the through gate 67). That is, before the ongoing variation stops, each time a ball enters the first winning opening 64 (or the second winning opening 640, the through gate 67) (each time the number of balls on hold increases), the rotating unit 500 lights up in order from the left end (the LED member 544 lights up). That is, in FIG. 35(a), a state with three balls on hold is illustrated.

[0503] The emission color of the rotating unit 500 can be changed according to the emission color of the LED member 544, and the difference in this emission color may be used to notify the difference in the jackpot expectation level (or small win expectation level, win expectation level, expectation level of the profit obtained by the player) of the corresponding variation.

[0504] The plurality of LED members 544 are configured such that the emission colors of the respective LEDs (for example, red, green, blue) are different, and a light emission effect of a plurality of colors can be executed with a small number of LEDs by combining the emission colors.

[0505] When the ongoing variation stops, the leftmost rotating unit 500 turns off (see FIG. 35(b)), and the corresponding hold display shifts one by one to the left (see FIG. 35(c)).

[0506] Since the rotating unit 500 can be displaced between the raised position and the lowered position as described above, as shown in FIG. 35(b), it can be controlled to rotate in a state of hiding a part of the third symbol display device 81 at the raised position.

[0507] Thereby, the attention to the rotating unit 500 can be improved. In addition, by associating the decorative pattern arranged on the front side of the rotating unit 500 with the magnitude standard of the jackpot expectation level (or small win expectation level, win expectation level, expectation level of the profit obtained by the player) of the corresponding variation and controlling them, the attention to the rotating unit 500 can be improved.

[0508] For example, in FIG. 35(b), the third rotating unit 500 from the left rises and rotates, and then the surface configuration member 560b is arranged on the front side, so that the decorative pattern of "?" is visually recognized by the player. Thereby, it is possible to notify the player that the expected degree of a big win (or the expected degree of a small win, the expected degree of a win, the expected degree of the profit obtained by the player) is unclear, and to attract the player's interest.

[0509] Note that the mode of attracting interest is not limited to this. For example, the mode of continuously rotating the rotating body 560 may be used, or the mode of rapidly flashing the LED member 544 may be used.

[0510] After that, as a result of the hold display shifting one by one to the left, the surface configuration member 560a is arranged on the front side in the second rotating unit 500 from the left, so that the decorative pattern of "△" is visually recognized by the player. When controlling so that the expected degree of a big win (or the expected degree of a small win, the expected degree of a win, the expected degree of the profit obtained by the player) is higher for the decorative pattern of "△" than for the decorative pattern of "○", it is possible to improve the attention to the variation corresponding to the second rotating unit 500 from the left.

[0511] Note that the notification of the expected degree of a big win (or the expected degree of a small win, the expected degree of a win, the expected degree of the profit obtained by the player) may be executed by changing the color or form of the hold display displayed corresponding to the number of hold balls on the third symbol display device 81. Further, control may be performed so as to associate the hold display displayed on the third symbol display device 81 with the state of the rotating unit 500. Further, an effect such as providing a time difference between the change of the hold display and the change of the state of the rotating unit 500 may be adopted.

[0512] As shown in FIG. 35(c), as the correspondence of the hold display is shifted one by one to the left, the third rotating unit 500 from the left turns off and is displaced to the lowered position. Due to this displacement, the hidden range of the third symbol display device 81 becomes visible. By depicting a display that raises the player's expectations (for example, a display indicating "COIN") within this range, it is possible to improve the attention paid to the third symbol display device 81 after the rotating unit 300 is displaced to the lowered position.

[0513] Thus, according to the present embodiment, not only can the player's attention be improved by controlling the rotating unit 500 in relation to the variation of symbols and the number of hold balls, but also the display area of the third symbol display device 81 can be partially hidden, thereby functioning as an eye mask when changing the display of the third symbol display device 81.

[0514] At this time, as an auxiliary effect of improving the attention to the rotating unit 500 that partially hides the third symbol display device 81, from the state where the player's attention is focused on the rotating unit 500 arranged on the front side of the third symbol display device 81 (see FIG. 35(b)), by retracting the rotating unit 500 (see FIG. 35(c)), the player's line of sight can be left directed towards the third symbol display device 81. As a result, the player's line of sight can be induced towards the third symbol display device 81, so that the attention paid to the third symbol display device 81 can be improved.

[0515] From the state shown in FIG. 35(c), if the correspondence of the hold display is shifted two places to the left and the variation corresponding to the hold where the decorative pattern of "△" is illustrated in FIG. 35(c) is a big win, then a plurality of rotators 560 are arranged in the raised position as shown in FIG. 35(d) and the surface constituent member 560c is arranged on the front side until the variation stops, so that the player can visually recognize a character string "HIT!" (a character string that reminds the player of a state where they can obtain some benefit such as a big win).

[0516] In this case, regardless of the number of held balls, it is preferable to turn on the LED member 544. Thereby, the rotating unit 500 can be made to emit light brilliantly, and an effect that arouses the expectation of the player can be executed.

[0517] As described above, according to the present embodiment, it is possible to configure an effect of visually recognizing the plurality of rotators 560 individually and an effect of visually recognizing the plurality of rotators 560 collectively. Here, the effect of visually recognizing the plurality of rotators 560 collectively is not limited to the mode shown in FIG. 35(d), and various modes are exemplified.

[0518] For example, as shown in FIG. 35(e), by arranging the third rotator 560 from the left in the lowered position and the remaining rotators 560 in the raised position, a string of characters "HI!" (a string of characters that reminds one of a greeting) can be made visible to the player.

[0519] By controlling the state shown in FIG. 35(e) to occur periodically in the waiting state before the player starts the game, the interest of the player can be attracted.

[0520] Also, for example, as shown in FIG. 35(f), if only the surface configuration member 560b of the rightmost rotator 560 faces the front side, a string of characters "HIT?" can be made visible to the player.

[0521] In this case, the interest of the player can be attracted due to the expectation that it might change to "HIT!" soon. Also, such an effect may be performed. That is, from the state of FIG. 35(f), it may be configured to be controllable to rotate the rightmost rotator 560 and change to the state of FIG. 35(d).

[0522] FIG. 36(a) and FIG. 36(b) are left side views of the detection sensor 547 and the driven plate 575 of the rotatable right lid portion 570. In FIG. 36(a), a state is shown in which the detection sensor 547 is disposed at one end (front end in FIG. 36(a)) of the non-formation range of the detected portion 577, and in FIG. 36(b), a state is shown in which the detection sensor 547 is disposed at the opposite end (rear end in FIG. 36(b)) of the non-formation range of the detected portion 577.

[0523] The states shown in FIGS. 36(a) and 36(b) both indicate a state of waiting for rotation (stop state). That is, in FIG. 36(a), from the time when the detected portion 577 retreats from the detection groove of the detection sensor 547 during the rotation of the rotating body 560, the drive motor 541 is stopped after rotating by an angle (30 degrees in this embodiment) that is half of the angle α1 (60 degrees in this embodiment) of the non-formation range of the detected portion 577. In FIG. 36(b), a state is shown in which the drive motor 541 is stopped immediately after the detected portion 577 enters the detection groove of the detection sensor 547 with the rotating body 560 rotated counterclockwise as viewed from the left side.

[0524] The angular difference between the states shown in FIGS. 36(a) and 36(b) depends on the angle of the non-formed portion of the detected portion 577. In this embodiment, the detected portion 577 is formed such that the angle α1 of the non-formed portion is 60 degrees, and the angular difference between the states shown in FIGS. 36(a) and 36(b) is about 45 degrees.

[0525] This angular difference is designed in association with the direction of the player's line of sight that changes as the rotating unit 500 moves up and down. That is, when the rotating unit 500 is disposed at the upper position, the line of sight of the player looking at the rotating unit 500 is in a substantially horizontal direction. Therefore, stopping the rotating body 560 in the posture shown in FIG. 36(a) can make it easier to see the decorative pattern of the rotating body 560 and enhance the production effect of the rotating body 560.

[0526] On the other hand, when the rotating unit 500 is disposed at the lowered position, since the line of sight of the player looking at the rotating unit 500 is in the downward viewing direction, stopping the rotating body 560 in the posture shown in FIG. 36(b) makes it easier to show the decorative pattern of the rotating body 560 to the player, and the effect of the rotating body 560 can be enhanced.

[0527] As described above, in the present embodiment, by configuring a plurality of types of stop postures of the rotating unit 500 in relation to the line of sight of the player who visually recognizes the rotating unit 500, regardless of whether the rotating unit 500 is disposed at the raised position or the lowered position, the rotating body 560 can be stopped in a posture that makes it easy for the player to see the decorative pattern of the rotating body 560.

[0528] The reason why the correspondence relationship between the detection sensor 547 and the detected portion 577 is different between the state shown in FIG. 36(a) and the state shown in FIG. 36(b) is due to the difference in the effect mode (for example, the rotation speed of the rotating body 560) using the rotating body 560.

[0529] That is, the state shown in FIG. 36(a) is the stop position in the state where the rotating unit 500 is disposed at the raised position. However, in the state where the rotating unit 500 is disposed at the raised position, since the attention of the player is sufficiently focused on the rotating unit 500, by reducing the rotation speed of the rotating body 560 and stopping it slowly, the player's interest can be improved over a long period of time.

[0530] For example, by slowly rotating the rotating body 560 to produce the change from the state shown in FIG. 35(f) to the state shown in FIG. 35(d), the period during which the player's sense of expectation increases can be lengthened, and the attention of the rotating body 560 can be maintained. Therefore, even if the rotating body 560 is rotated by an angle equal to half of the non-forming range of the detected portion 577 (about 30 degrees in the present embodiment) after the position is determined by the detection sensor 547 and then stopped, the possibility that the stop posture of the rotating body 560 deviates is low, and the rotating body 560 can be easily stopped in the posture shown in FIG. 36(a).

[0531] According to this control mode, the rotating body 560 can be stopped in the posture shown in Fig. 36(a) in the same control mode regardless of the rotation direction of the rotating body 560. Therefore, since the control mode for stopping after forward rotation and the control mode for stopping after reverse rotation can be selected depending on the case, it is possible to make it difficult to predict the operation mode until the rotating body 560 stops. Thereby, the interest of the player can be improved.

[0532] The state shown in Fig. 36(b) is the stop position when the rotating unit 500 is disposed at the lowered position. However, when the rotating unit 500 is disposed at the lowered position, in many cases, the player's attention is not sufficiently focused on the rotating unit 500. Therefore, it is easier to improve the player's interest by increasing the rotation speed of the rotating body 560.

[0533] In the case of high-speed rotation, when performing control to stop after rotating by an angle that is half of the non-formation range of the detected portion 577 (about 30 degrees in this embodiment) after determining the position with the detection sensor 547, there is a possibility that the stop position of the rotating body 560 may shift. Therefore, as shown in Fig. 36(b), it is possible to suppress the shift of the stop position of the rotating body 560 by stopping the drive motor 541 immediately after the detected portion 577 enters the detection groove of the detection sensor 547.

[0534] The rotation control of the rotating unit 500 is to rotate at a rotation angle (90 degrees, 180 degrees, 270 degrees) set at 90-degree intervals from the above-described plurality of types of stop positions and then stop, so that any one of the surface constituent members 560a to 560d can be stopped in a posture visible to the player.

[0535] As described above, the postures shown in Fig. 36(a) and Fig. 36(b) are configured to be able to respond to changes in the player's line of sight. However, in any line of sight, it is possible to avoid the drive motor 541 (see Fig. 25) from being visible to the player.

[0536] That is, since the drive motor 541 is disposed inside the rotating body 560, the rotating body 560 can block the player's line of sight regardless of the direction of the player's line of sight, and it is possible to prevent the drive motor 541 from being visually recognized by the player.

[0537] As shown in FIGS. 36(a) and 36(b), in the rotating unit 500, a configuration for detecting the angle of the rotating body 560 is disposed inside the rotating body 560. Therefore, a decorative pattern can be applied to most parts outside the rotating body 560, and the production effect of the rotating body 560 can be improved.

[0538] Also, while omitting the arrangement of a light-shielding portion (a configuration for preventing the configuration for angle detection from being visually recognized) that may be required when the configuration for detecting the angle is disposed outside the rotating body 560, the rotating body 560 can be configured to be rotatable by one rotation or more.

[0539] FIGS. 37 and 38 are front perspective views of the second operation unit 700, and FIGS. 39 and 40 are rear perspective views of the second operation unit 700. In FIGS. 37 and 39, a standby state of the second operation unit 700 in which the displacement base member 720 and the effect means 780 are disposed at the standby position (the ascending end position) is illustrated. In FIGS. 38 and 40, a state in which the displacement base member 720 and the effect means 780 are disposed at the protruding position (the descending end position) protruding in front of the third symbol display device 81 is illustrated.

[0540] The second operation unit 700 is characterized in that each movable part is displaced so as to reduce the displacement amount of the electrical wirings DK2 and DK3 guided to each movable part for electrical supply, and is provided with a spring cover SC1 for hiding the coil spring SP1 so as not to be visible in a front view, and the spring cover SC1 enters inward of the displacement base member 720 and the effect means 780. Details will be described later. The coil spring SP1 is illustrated as a quadrangular columnar shape that is schematically curved.

[0541] FIG. 41 is an exploded front perspective view of the second operation unit 700, and FIG. 42 is an exploded rear perspective view of the second operation unit 700. Further, FIG. 43 is an exploded front perspective view of the fixed base member 701, the displacement base member 720, the driving means 730, the transmission means 740, and the biasing means 750, and FIG. 44 is an exploded rear perspective view of the fixed base member 701, the displacement base member 720, the driving means 730, the transmission means 740, and the biasing means 750. That is, in FIG. 43, a part of FIG. 41 and in FIG. 44, a part of FIG. 42 are respectively enlarged and shown.

[0542] Further, FIG. 45 is an exploded front perspective view of the supported means 760L, 760R and the connecting means 770, and FIG. 46 is an exploded rear perspective view of the supported means 760L, 760R and the connecting means 770. That is, in FIG. 45, a part of FIG. 41 and in FIG. 46, a part of FIG. 42 are respectively enlarged and shown.

[0543] Further, FIG. 47 is an exploded front perspective view of the effect means 780, and FIG. 48 is an exploded rear perspective view of the effect means 780. That is, in FIG. 47, a part of FIG. 41 and in FIG. 48, a part of FIG. 42 are respectively enlarged and shown.

[0544] Further, FIG. 49 is a partial cross-sectional view of the second operation unit 700 in a plane extending horizontally through the columnar fastening portion 705c of the support means 705. In the description of FIGS. 41 to 49, FIGS. 37 to 40 are appropriately referred to.

[0545] As shown in FIGS. 41 to 44, the second operation unit 700 includes a horizontally long fixed base member 701 fastened and fixed to the bottom wall portion 311 of the back case 310, a displacement base member 720 disposed on the front side of the base member 701 and configured to be displaceable in the vertical direction with respect to the fixed base member 701, a driving means 730 for generating a driving force for displacing the displacement base member 720, a transmission means 740 configured to transmit the driving force generated from the driving means 730 to the displacement base member 720, a biasing means 750 for applying an upward biasing force to the displacement base member 720, pivotally supported means 760L and 760R disposed in a pair on the displacement base member 720 and having one end (the end on the left and right central side) pivotally supported rotatably, a pair of connecting means 770 for connecting the other ends (the ends on the left and right outer sides) of the pivotally supported means 760L and 760R and the left and right end portions of the fixed base member 701, and an effect means 780 fastened and fixed to the front side of the displacement base member 720 for the purpose of decoration in a front view, mainly.

[0546] The fixed base member 701 is formed of a synthetic resin material, and includes a main body plate portion 702 formed in a horizontally long plate shape, a plurality of cover support protrusions 703 protruding in a rod shape with the same length from the main body plate portion 702 to the front side and having a spring cover SC1 fastened and fixed to the tip thereof, a spring support portion 704 extending from the main body plate portion 702 to the front side above the cover support protrusion 703 at the left end, a support means 705 for supporting gear members such as a transmission gear 734 and a final gear 745 for driving force transmission, a circular protrusion portion 708 which is a portion for pivotally supporting the rotation arm member 743 of the transmission means 740 and is substantially circular in a front view and protrudes to the front side, a metal slide rail 711 having a back plate fixed to the left and right central portions of the main body plate portion 702 in a posture slidable vertically, a pair of cylindrical protrusion portions 714 protruding in a cylindrical shape in a front view from a position raised above the circular protrusion portion 708, a pair of left and right upper end stoppers 717 arranged in parallel with the cylindrical protrusion portions 714 above the cylindrical protrusion portions 714, and a pair of left and right lower end stoppers 719 formed having a plane along the radial direction of the cylindrical protrusion portions 714 at a position behind the front and rear positions for pivotally supporting the connecting means 770 of the cylindrical protrusion portions 714, mainly.

[0547] The support means 705 mainly includes a columnar fastening portion 705a protruding in a columnar shape slightly shorter in diameter than the opening of the transmission gear 734 from the back surface of the plate of the fixed base member 701 and having a female screw formed at the tip; an annular recessed portion 705b recessed in a double annular shape from the front surface of the plate of the fixed base member 701; a columnar fastening portion 705c protruding in a columnar shape from the front surface of the plate of the fixed base member 701 at the center position of the annular recessed portion 705b and having a female screw formed at the tip; a plurality of protrusion portions 705d formed as protrusions extending in the front-rear direction on the side surface of the annular recessed portion 705b; and a tooth-use opening 705e formed in the inner peripheral surface of the outermost periphery of the annular recessed portion 705b.

[0548] The annular recessed portion 705b is formed with a diameter and width capable of arranging the annular portion (the annular portion having a gear formed on the outer periphery) of the terminal gear 745. By screwing a fastening screw inserted through the opening formed in the center of the terminal gear 745 into the columnar fastening portion 705c, the terminal gear 745 is rotatably supported.

[0549] The protrusion portions 705d are arranged at eight positions at 45-degree intervals and are formed with a protruding height such that the tips can abut against the inner periphery of the annular portion of the terminal gear 745. Thereby, compared with the case where circles are fitted to each other, while maintaining the function of stabilizing the rotation axis of the terminal gear 745 (stability of the supported state), the contact area between the annular portion of the terminal gear 745 and the annular recessed portion 705b can be reduced. Thereby, the driving force required to rotate the terminal gear 745 can be reduced.

[0550] The tooth-use opening 705e is formed to open across the inner circumference of the annular recessed portion 705b and the bottom portion on the back side. Regarding the bottom portion on the back side, at least an opening is formed at a position overlapping with a circle (the circle of the outermost diameter of the transmission gear 734) centered on the columnar fastening portion 705a in a rear view. Thereby, the transmission gear 734 can be pivotally supported by the columnar fastening portion 705a in a state of protruding inside the tooth-use opening 705e (the inner diameter side of the annular recessed portion 705b).

[0551] In this embodiment, the gear tooth portion of the transmission gear 734 that protrudes toward the inner diameter side of the annular recessed portion 705b through the tooth engagement opening 705e is configured to mesh with the gear tooth portion of the terminal gear 745. Thus, while the transmission gear 734 is attached to and pivotally supported by the fixed base member 701 from the back side, and the terminal gear 745 is attached to and pivotally supported by the fixed base member 701 from the front side, the driving force can be transmitted by the meshing transmission between the transmission gear 734 and the terminal gear 745.

[0552] The tooth engagement opening 705e is formed only at the location necessary for protruding the transmission gear 734 toward the inner diameter side of the annular recessed portion 705b, and no opening is formed at other locations. Thereby, it is possible to prevent the strength of the fixed base member 701 near the support means 705 from being excessively insufficient.

[0553] The circular protruding portion 708 includes positioning protruding pins 709 protruding from the front side end surface, and a plurality of protrusions 710 protruding in the radially outer direction over the protruding length.

[0554] The protrusion 710 is disposed between the rotating arm member 743 and the circular protruding portion 708, and functions to suppress the contact area between the rotating arm member 743 and the circular protruding portion 708. In this case, since the frictional resistance of the pivot portion, which is likely to be a problem when the circular protruding portion 708 is configured with a large diameter, can be reduced, the stability of the pivot state of the rotating arm member 743 can be achieved while reducing the frictional resistance generated with the displacement of the rotating arm member 743. Thereby, it is possible to suppress the driving force required to displace the second operation unit 700.

[0555] The metal slide rail 711 has a plurality of metal plates laminated in the front-rear direction, and the metal plate at the front side end is connected and fixed to the displacement base member 720. That is, the displacement base member 720 is guided by the metal slide rail 711 to displace in the vertical direction.

[0556] The cylindrical protruding portion 714 is a portion that pivotally supports the connecting means 770 rotatably by having an outer peripheral shape configured to be circular in a front view, and includes an opening 714a that penetrates in the front-rear direction, a plurality of protruding pins 715 for alignment that protrude from the front-side end to the front side, and a plurality of fastening portions 716 formed with female threads at the front-side end in a portion where the protruding pins 715 are not provided.

[0557] The opening 714a serves as a passage route for the electrical wiring DK2. That is, the electrical wiring DK2 is guided to the front side through the opening 714a, and a member for fixing the wiring, such as a binding band, is fixed to the fixing-shaped portion 718 by being tightened to the front-side end portions of the left and right upper stoppers 717.

[0558] In the present embodiment, among the left and right upper stoppers 717, a fixing-shaped portion 718 having a shape through which a binding band can pass is formed so as to protrude from the front-side end surface of the left left and right upper stopper 717, and the fixing-shaped portion 718 is not formed on the right right and left upper stopper 717.

[0559] In this way, by forming the fixing-shaped portion 718 only on the left side where the electrical wiring DK2 is guided among the left and right upper stoppers 717 and omitting the formation on the opposite side, the shape of the fixing base member 701 can be simplified. Further, by not forming the fixing-shaped portion 718 at unnecessary locations, the working efficiency of the assembly worker can be improved.

[0560] Since the openings 714a are arranged in a pair on the left and right, the electrical wiring DK2 can also be guided to the front side at both the left and right ends. However, in the present embodiment, the electrical wiring DK2 is guided only through the left opening 714a, and the electrical wiring DK2 is not arranged in the right opening 714a.

[0561] Thereby, since it is not necessary to design the right cylindrical protruding portion 714 and the right connecting means 770 pivotally supported by the right cylindrical protruding portion 714 in consideration of the relationship with the electrical wiring DK2, the design freedom of the right cylindrical protruding portion 714, the right connecting means 770, and the surrounding configuration can be improved.

[0562] However, regardless of this, the electrical wiring DK2 may be passed through from both of the pair of left and right openings 714a to the front side and configured to be guided to the left and right shaft-supported means 760L and 760R, respectively. In this case, since it is easy to make the loads applied to the shaft-supported means 760L and 760R the same on the left and right via the electrical wiring DK2, it is possible to easily make the displacements of the shaft-supported means 760L and 760R that are driven to displace in accordance with the displacement of the displacement base member 720 symmetrical on the left and right.

[0563] The protruding pin 715 and the fastening portion 716 are formed so as to protrude toward the center side of a circle (circumscribed circle of the opening 714a) formed by connecting the surfaces that constitute the shape of the opening 714a and on which neither the protruding pin 715 nor the fastening portion 716 is disposed. That is, the inner peripheral shape of the cylindrical protruding portion 714 is different from the outer peripheral shape (circular shape) and is shaped such that the circle is recessed toward the central axis at a plurality of locations on the circumference.

[0564] Here, for example, when the inner peripheral shape of the cylindrical protruding portion 714 is a perfect circle, the durability of the electrical wiring DK2 may be reduced. That is, since the electrical wiring DK2 inserted through the opening 714a is connected to the electrical decoration substrate 764 of the shaft-supported means 760L and may be displaced in accordance with the displacement of the shaft-supported means 760L, if the degree of rubbing against the edge of the cylindrical protruding portion 714 is large with this displacement, the covering of the electrical wiring DK2 may be damaged early or the electrical wiring DK2 may be disconnected early.

[0565] As a countermeasure against this, a cylindrical intermediate member (collar) that is slidable between the cylindrical protruding portion 714 and the electrical wiring DK2 may be provided, or a separate covering member may be wound around the electrical wiring DK2. However, the cost of the separate member will increase, leading to an increase in the product cost.

[0566] On the other hand, by making the inner peripheral shape of the cylindrical protruding portion 714 a shape that is recessed toward the central axis at a plurality of locations on the circle, the displacement of the electrical wiring DK2 that is easily displaced along the edge of the opening 714a can be restricted at the locations of the protruding pin 715 and the fastening portion 716. Therefore, the degree of rubbing of the electrical wiring DK2 against the edge of the cylindrical protruding portion 714 can be suppressed to a small level.

[0567] This improvement does not require separate components and solves the problem by simply devising the inner peripheral shape of the opening 714a. Therefore, it is possible to improve the durability of the electrical wiring DK2 while suppressing an increase in product cost.

[0568] Note that, by winding a spiral tube around the electrical wiring DK2, the free displacement of the electrical wiring DK2 can be restricted. However, in this case, there is a risk that the resistance to the displacement of the second operation unit 700 will increase due to the rigidity of the spiral tube. In contrast, in the present embodiment, by omitting the arrangement of the spiral tube, the displacement resistance is reduced, and the free displacement of the electrical wiring DK2 is restricted by the change in the posture of the shaft-supported means 760 described later.

[0569] The left and right upper stoppers 717 are configured to be able to contact the lateral surface in the short side direction of the connecting means 770 pivotally supported by the cylindrical protruding portion 714, and the contact defines the upward displacement end of the connecting means 770. Thereby, the displacement angle of the connecting means 770 can be restricted.

[0570] The left and right lower stoppers 719 are configured to be able to contact the rotational direction side surface of the arc-shaped protrusion 775 of the connecting means 770 pivotally supported by the ...
