Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. First, with reference to FIGS. 1 to 63, as a first embodiment, an embodiment in which the present invention is applied to a pachinko game machine (hereinafter simply referred to as a "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.

[0014] As shown in FIG. 1, the pachinko machine 10 includes an outer frame 2 whose outer shell is formed by a wooden frame combined in a substantially rectangular shape, and an inner frame 4 formed in substantially the same outer shape as the outer frame 2 and supported so as to be openable and closable with respect to the outer frame 2. On the outer frame 2, metal hinges 18 are attached at two upper and lower positions on the left side in the front view (see FIG. 1) to support the inner frame 4, and the inner frame 4 is supported so as to be openable and closable toward the front side with the side provided with the hinges 18 as the axis of opening and closing.

[0015] On the inner frame 4, a game board 13 (see FIG. 2) having a large number of nails and 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 surface of the game board 13. Note that on the inner frame 4, a ball launching unit 112a (see FIG. 4) for launching balls into the front area of the game board 13, 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, and the like are attached.

[0016] On the front side of the inner frame 4, a front door 5 covering the upper side of the front surface and a lower dish unit 15 covering the lower side are provided. Metal hinges 19 are attached at two upper and lower positions on the left side in the front view (see FIG. 1) to support the front door 5 and the lower dish unit 15, and the front door 5 and the lower dish unit 15 are supported so as to be openable and closable toward the front side with the side provided with the hinges 19 as the axis of opening and closing. Note that the locking of the inner frame 4 and the locking of the front door 5 are each released by inserting a dedicated key into the keyhole 21 of the cylinder lock 20 and performing a predetermined operation.

[0017] The front door 5 is assembled with resin parts for decoration, electrical parts, etc., and a window portion 5c having an opening formed in a substantially elliptical shape is provided at substantially the center thereof. On the back side of the front door 5, a glass unit 16 having two plate glasses 8 is disposed, and the front surface 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 door 5, an upper tray 17 for storing balls is formed in a substantially box shape that protrudes forward and has an open upper 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 in a front view (see Fig. 1), and due to this slope, the balls put 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 mode of the effects displayed by the segment display device 600 and the decorative pattern display device 800 (see Fig. 2), or when changing the content of the super reach effect.

[0019] On the front door 5, light-emitting means such as various lamps are provided around its periphery (for example, corner portions). These light-emitting means have their light-emitting modes changed and controlled by lighting or flashing according to changes in the gaming state during a big win or a predetermined reach, etc., and play a role in enhancing the production effect during the game. Around the periphery of the window portion 5c, ornamental parts 29 to 33 incorporating light-emitting means such as LEDs are provided. In the pachinko machine 10, these ornamental parts 29 to 33 function as production lamps such as big win lamps, and during a big win or a reach production, each ornamental part 29 to 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 part in a front view (see Fig. 1) of the front door 5, 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 ornamental part 32 on the right side, a small window 35 is formed by attaching a transparent resin from the back side so that the back side of the front door 5 can be seen, and certificates or the like pasted in the pasting space K1 in 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, in order to create a more magnificent atmosphere, a plating member 36 made of ABS resin with chrome plating is attached to the area around the ornamental parts 29 to 33.

[0021] Below the window portion 5c, 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, etc. 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 an internally built-in LED lights up and the balance is displayed numerically as the 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 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. It is possible to make the pachinko machine using the card unit and the cash machine 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 at its central portion. On the right side of the lower tray 50, an operation handle 51 operated by a player to drive the balls into the front surface of the game board 13 is disposed.

[0023] Inside the operation handle 51, there are a touch sensor 51a for permitting the driving of the ball launching unit 112a, a firing stop switch 51b for stopping the firing of the ball during the period of the pressing operation, a variable resistor (not shown) for detecting the amount of rotational operation (rotational position) of the operation handle 51 by the change in electrical 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 amount of rotational operation, and the ball is launched with a strength (launch intensity) corresponding to the resistance value of the variable resistor, whereby the ball is driven into the front surface of the game board 13 with a jump amount corresponding to the operation of the player. Further, when the operation handle 51 is not being operated by the player, the touch sensor 51a and the firing stop switch 51b are turned off.

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

[0025] As shown in FIG. 2, the game board 13 is formed by assembling a base plate 60 that has been machined into a substantially square shape when viewed from the front, with a number of pins for guiding balls (not shown), windmills, rails 76 and 77, a general winning opening 63, a first winning opening 64, a second winning opening 140, a variable winning device 65, a first through gate 66, a variable display device unit 80, etc., and the peripheral portion thereof is attached to the back side of the inner frame 4 (see FIG. 1). The base plate 60 is made of wood with thin plates laminated together, and various structures arranged from the front side to the back side of the base plate 60 are formed so as not to be visible to the player. The general winning opening 63, the first winning opening 64, the second winning opening 140, the variable winning device 65, and the variable display device unit 80 are arranged in through holes 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.

[0026] The central front portion of the game board 13 can be visually recognized from the front side of the inner frame 4 through the window portion 5c (see FIG. 1) of the front door 5. Hereinafter, the configuration of the game board 13 will be mainly described with reference to FIG. 2.

[0027] On the front surface of the game board 13, an outer rail 77 formed by bending a strip-shaped metal plate into a substantially arc shape is erected, and at an inner position of the outer rail 77, an arc-shaped inner rail 76 formed of a strip-shaped metal plate similar to the outer rail 77 is erected. The inner rail 76 and the outer rail 77 surround the outer periphery of the front surface of the game board 13, 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 balls is formed on the front surface of the game board 13. The game area is an area (an area where winning openings and the like are arranged and the launched balls flow down) defined by the front surface of the game board 13, the two rails 76 and 77, and a resin outer edge member 73 connecting between the rails.

[0028] The two rails 76 and 77 are provided to guide the balls 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 of the inner rail 76 (the upper left portion in FIG. 2), preventing a situation where a ball once guided to the upper part of the game board 13 returns into the ball guiding passage again. A return rubber 69 is attached to the tip portion of the outer rail 77 (the upper right portion in FIG. 2) at a position corresponding to the maximum flight portion of the ball. A ball launched with a momentum above a predetermined level hits the return rubber 69 and bounces back toward the central portion while its momentum is attenuated.

[0029] On the lower left side in the front view of the game area (the lower left side in FIG. 2), first symbol display devices 37A and 37B including a plurality of LEDs and a 7-segment display, which are light emitting means, are arranged. The first symbol display devices 37A and 37B perform displays according to each control performed by the main control device 110 (see FIG. 4), mainly displaying the game 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 a ball wins at the first winning opening 64 or at the second winning opening 140. Specifically, when a ball wins at the first winning opening 64, the first symbol display device 37A operates, while when a ball wins at the second winning opening 140, the first symbol display device 37B operates.

[0030] Further, the first symbol display devices 37A and 37B use the LEDs to indicate whether the pachinko machine 10 is in the probability variation state, the time shortening state, or the normal state by the lighting state, indicate whether it is in the variation state or not by the lighting state, indicate whether the stop symbol corresponds to a probability variation big win symbol, a normal big win symbol, or a losing symbol by the lighting state, indicate the number of hold balls by the lighting state, and perform display of the number of rounds during a big win and error display by the 7-segment display device. The plurality of LEDs are configured such that the emission colors of the respective LEDs (for example, red, green, blue) are different, and various game states of the pachinko machine 10 can be suggested with a small number of LEDs by the combination of the emission colors.

[0031] In the pachinko machine 10, a lottery is conducted when a winning occurs in either the first winning opening 64 or the second winning opening 140. In this lottery, the pachinko machine 10 determines whether it is a big win (big win lottery), and if it is determined to be a big win, it also determines the type of big win. The types of big wins determined here are 15R sure-change big win, 4R sure-change big win, and 15R normal big win. The first symbol display devices 37A and 37B show not only whether the result of the lottery is a big win as the stopped symbol after the variation ends, but also show a symbol corresponding to the type of big win if it is a big win.

[0032] Here, the "15R sure-change big win" is a sure-change big win in which the maximum number of rounds is 15 rounds and it transitions to a high-probability state after a big win, and the "4R sure-change big win" is a sure-change big win in which the maximum number of rounds is 4 rounds and it transitions to a high-probability state after a big win. Also, the "15R normal big win" is a big win in which, after a big win with a maximum number of rounds of 15 rounds, it transitions to a low-probability state and becomes a time-saving state for a predetermined number of variations (for example, 100 variation times).

[0033] Also, the "high-probability state" refers to a state in which the big win probability increases as an added value after the big win ends, that is, during so-called probability variation (during sure change). In other words, it is a game state in which it is easy to transition to a special game state. The high-probability state (during sure change) in this embodiment includes a game state in which the winning probability of the second symbol increases and it is easy for the ball to win in the second winning opening 140. The "low-probability state" refers to a time when it is not during sure change, and is a state where the big win probability is normal, that is, a state where the big win probability is lower than during sure change. Also, the time-saving state (during time saving) among the "low-probability states" refers to a game state in which the big win probability is normal and the winning probability of only the second symbol increases while the big win probability remains the same, making it easy for the ball to win in the second winning opening 140. On the other hand, when the pachinko machine 10 is in the normal state, it is a game state that is neither during sure change nor during time saving (a state where neither the big win probability nor the winning probability of the second symbol increases).

[0034] During probability variation or time shortening, not only does the winning probability of the second symbol increase, but also the time during which the first electric accessory 520 associated with the second winning opening 140 is opened is changed, and a longer time is set compared to normal. When the first electric accessory 520 is in the opened state (open state), the balls are more likely to win the second winning opening 140 compared to when the first electric accessory 520 is in the closed state (closed state). Therefore, during probability variation or time shortening, the balls are more likely to win the second winning opening 140, and the number of times the jackpot lottery is conducted can be increased.

[0035] Note that during probability variation or time shortening, instead of changing the opening time of the first electric accessory 520 associated with the second winning opening 140, or in addition to changing the opening time, a change may be made to increase the number of times the first electric accessory 520 is opened per win compared to normal. Also, during probability variation or time shortening, the winning probability of the second symbol may not be changed, and at least one of the time during which the first electric accessory 520 associated with the second winning opening 140 is opened and the number of times the first electric accessory 520 is opened per win may be changed. Further, during probability variation or time shortening, the time during which the first electric accessory 520 associated with the second winning opening 140 is opened and the number of times the first electric accessory 520 is opened per win may not be changed, and only the winning probability of the second symbol may be changed to increase compared to normal.

[0036] In the game area, a plurality of general winning openings 63 are provided, where 5 to 15 balls are paid out as prize balls when a ball wins. Also, in the central part of the game area, a variable display device unit 80 is provided. The variable display device unit 80 includes a segment display device 600 and a decorative symbol display device 800 that perform variable display of the third symbol while being synchronized with the variable display in the first symbol display devices 37A and 37B, triggered by a win (starting win) at either the first winning opening 64 or the second winning opening 140, and a second symbol display device (not shown) composed of LEDs that perform variable display of the second symbol triggered by the passage of a ball through the first through gate 66.

[0037] Further, a center frame 86 is disposed around the outer peripheries of the segment display device 600 and the decorative symbol display device 800 in the variable display device unit 80. The segment display device 600 and the decorative symbol display device 800 are visible through an opening formed at the center of the center frame 86.

[0038] In this embodiment, the segment display device 600 and the decorative symbol display device 800 perform decorative displays and displacement operations corresponding to the displays of the first symbol display devices 37A and 37B, while the display of the game state according to the control of the main control device 110 (see FIG. 4) is performed by the first symbol display devices 37A and 37B. Instead of the segment display device 600 and the decorative symbol display device 800, for example, a liquid crystal display may be used to display the game state.

[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 first through gate 66. In the pachinko machine 10, when it is detected that the ball has passed through the first through gate 66, a winning lottery is conducted. As a result of the winning lottery, if it is a win, the symbol of "○" is stopped and displayed on the second symbol display device after the variable display of the second symbol. Also, as a result of the winning lottery, if it is a miss, the symbol of "×" is stopped and displayed on the second symbol display device after the variable display of the third symbol.

[0040] The pachinko machine 10 is configured such that when the variable display on the second symbol display device stops at a predetermined symbol (the symbol of "○" in this embodiment), the first electric accessory 520 associated with the second winning opening 140 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 the probability increase state or the time shortening state than when the game state is normal. As a result, during the probability increase state and the time shortening state, since the variable display of the second symbol is performed in a short time, more winning lotteries can be conducted than during the normal state. Therefore, since the chance of winning in the winning lottery increases, more opportunities for the first electric accessory 520 of the second winning opening 140 to be in the open state can be given to the player. Thus, during the probability increase state and the time shortening state, it is possible to make the state such that balls are likely to win in the second winning opening 140.

[0042] In addition, during the probability increase state or the time shortening state, when the state is made such that balls are likely to win in the second winning opening 140 by other methods such as increasing the winning probability or increasing the opening time or the number of opening times of the first electric accessory 520 for one win, 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 the time taken for the variable display of the second symbol is set to be shorter during the probability increase state or the time shortening state than during the normal state, the winning probability may be made constant regardless of the game state, or the opening time or the number of opening times of the first electric accessory 520 for one win may be made constant regardless of the game state.

[0043] The first through gate 66 is assembled to the game board in the area on the right side of the variable display device unit 80. The first through gate 66 is configured such that a part of the balls flowing down the game board among the balls launched onto the game board can pass through. When a ball passes through the first through gate 66, a winning lottery for the second symbol is conducted. After the winning lottery, variable display is performed on the second symbol display device, and if the result of the winning lottery is a win, the symbol of "○" is displayed as the stopped symbol of the variable display, and if the result of the winning lottery is a miss, the symbol of "×" is displayed as the stopped symbol of the variable display.

[0044] The number of times the ball passes through the first through gate 66 is reserved up to a maximum of 4 times in total. The number of reserved balls is displayed by the first symbol display devices 37A and 37B described above and is also lit and displayed on a second symbol reservation lamp (not shown). Four second symbol reservation lamps are provided corresponding to the maximum number of reservations, and they are arranged symmetrically left and right below the segment display device 600 and the decorative symbol display device 800.

[0045] Note that the variable display of the second symbol is performed by switching the lighting and non-lighting of a plurality of lamps in the second symbol display device as in the present embodiment. However, it may also be performed using a part of the first symbol display devices 37A and 37B, the segment display device 600, and the decorative symbol display device 800. Similarly, the lighting of the second symbol reservation lamp may be performed using a part of the segment display device 600 and the decorative symbol display device 800. Also, the maximum number of reserved balls for the passage of the ball through the first through gate 66 is not limited to 4 times, and it may be set to 3 times or less, or 5 times or more (for example, 8 times). Also, the number of assembled through gates is not limited to 2, and may be a plurality of 3 or more. Also, the assembly position of the through gate is not limited to the left and right sides of the variable display device unit 80, and may be, for example, below the variable display device unit 80. Also, since the number of reserved balls is indicated by the first symbol display devices 37A and 37B, it may not be lit and displayed by the second symbol reservation lamp.

[0046] Below the variable display device unit 80, a first winning port 64 through which the ball can win is arranged. When the 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 a jackpot lottery is performed by the main control device 110 (see FIG. 4) due to the turning on of the first winning port switch, and a display corresponding to the lottery result is shown on the first symbol display device 37A.

[0047] On one side, to the right of the front view of the first winning opening 64, a second winning opening 140 into which a ball can win is provided. When a ball wins in the second winning opening 140, a second winning opening switch (not shown) provided on the back side of the game board 13 is turned on, and a jackpot lottery is conducted by the main control device 110 (see FIG. 4) due to the turning on of the second winning opening switch, and a display corresponding to the lottery result is shown on the first symbol display device 37B.

[0048] Also, the first winning opening 64 and the second winning opening 140 are each one of the winning openings from which 5 balls are paid out as prize balls when a ball wins. In this embodiment, the number of prize balls paid out when a ball wins in the first winning opening 64 and the number of prize balls paid out when a ball wins in the second winning opening 140 are configured to be the same. However, the number of prize balls paid out when a ball wins in the first winning opening 64 and the number of prize balls paid out when a ball wins in the second winning opening 140 may be different numbers. For example, the number of prize balls paid out when a ball wins in the first winning opening 64 may be 3, and the number of prize balls paid out when a ball wins in the second winning opening 140 may be 5.

[0049] A first electric accessory 520 is attached to the second winning opening 140. This first electric accessory 520 is configured to be openable and closable, and normally the first electric accessory 520 is in a closed state (contracted state), making it difficult for a ball to win in the second winning opening 140. 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 first through gate 66, the first electric accessory 520 is in an open state (expanded state), making it easy for a ball to win in the second winning opening 140.

[0050] As described above, during the probability variation state and the time shortening state, the winning probability of the second symbol is higher than that during the normal state, and the time taken for the variable display of the second symbol is also shorter. Therefore, in the variable display of the second symbol, the symbol "○" is more likely to be displayed, and the number of times the first electric accessory 520 is in the open state (expanded state) increases. Furthermore, during the probability variation state or the time shortening state, the time during which the first electric accessory 520 is open is also longer than that during the normal state. Therefore, during the probability variation state or the time shortening state, it is possible to create a state in which balls are more likely to win the second winning opening 140 compared to the normal time.

[0051] Here, the probability of a big win is the same whether a ball wins the first winning opening 64 or the second winning opening 140, regardless of whether it is in the low probability state or the high probability state. However, the probability of becoming a 15R probability variation big win, which is the type of big win selected when a big win occurs, is set higher when a ball wins the second winning opening 140 than when a ball wins the first winning opening 64. On the other hand, the first winning opening 64 does not have the first electric accessory 520 as in the second winning opening 140, and balls can always win.

[0052] Therefore, during the normal state, since the electric accessory associated with the second winning opening 140 is often in the closed state and it is difficult for balls to win the second winning opening 140, it is advantageous for the player to aim for a big win by shooting the ball so that it passes through the left side of the variable display device unit 80 towards the first winning opening 64 without an electric accessory (so-called "left shooting") and obtaining more opportunities for the big win lottery by winning the first winning opening 64.

[0053] On the other hand, during the probability variation state or the time shortening state, by passing the ball through the first through gate 66, the first electric accessory 520 associated with the second winning opening 140 is likely to be in the open state, and it is a state where it is easy for balls to win the second winning opening 140. Therefore, it is advantageous for the player to aim for a 15R probability variation big win by shooting the ball so that it passes through the right side of the variable display device unit 80 towards the second winning opening 140 (so-called "right shooting"), passing the first through gate 66 to open the first electric accessory 520, and winning the second winning opening 140.

[0054] In this way, the pachinko machine 10 of the present embodiment can cause the player to change the way of shooting the ball between "left shooting" and "right shooting" according to the game state of the pachinko machine 10 (whether it is in the probability variation state, the time shortening state, or the normal state). Therefore, the way of shooting the ball can be changed for the player, so that the player can enjoy the game.

[0055] A variable winning device 65 is disposed on the right side of the first winning port 64, and a horizontally long rectangular specific winning port (large opening) 65a is provided in the substantially central portion thereof. In the pachinko machine 10, when the jackpot lottery conducted due to the winning of either the first winning port 64 or the second winning port 140 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 segment display device 600 and the decorative symbol display device 800 to indicate the occurrence of the jackpot. Thereafter, the game state transitions to a special game state (jackpot) in which it is easy for the ball to win. As this special game state, the specific winning port 65a, which is normally closed, is opened for a predetermined time (for example, until 30 seconds elapse, or until 10 balls win).

[0056] This specific winning port 65a is closed when a predetermined time has elapsed, and after the closure, the specific winning port 65a is opened again for a predetermined time. The opening and closing operation of this specific winning port 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 an imparting of game value (game value) than in the normal time.

[0057] The variable winning device 65 specifically includes a horizontally long rectangular opening / closing plate that covers the specific winning opening 65a, and a large-opening solenoid (not shown) for driving the opening / closing drive forward with the lower side of the opening / closing plate as the axis. The specific winning opening 65a is normally in a closed state where balls cannot win or it is difficult for balls to win. During a big win, the large-opening solenoid is driven to tilt the opening / closing plate downward in the front, temporarily forming an open state in which balls can easily win the specific winning opening 65a, and it operates to alternately repeat the open state and the normal closed state.

[0058] 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, and 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 is opened for a predetermined time and a predetermined number of times, and this game state can be formed as a special game state. Also, the specific winning opening 65a is not limited to one, and one or a plurality (for example, three) may be arranged, and the arrangement position is not limited to the right side of the first winning opening 64, and may be, for example, to the left of the variable display device unit 80.

[0059] At the lower right corner of the game board 13, an attachment space K1 for attaching certificates, identification labels, etc. is provided, and the certificates, etc. attached to the attachment space K1 can be visually recognized through the small window 35 (see FIG. 1) of the front door 5.

[0060] The game board 13 is provided with a first out port 71. Balls flowing down in the game area that did not win any of the winning openings 63, 64, 65a, 640 are guided through the first out port 71 to a ball discharge path (not shown). The first out port 71 is disposed below the first winning opening 64.

[0061] A large number of nails are implanted in the game board 13 to appropriately disperse and adjust the falling direction of the balls, and various members (effect devices) such as windmills are arranged.

[0062] 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.

[0063] The back pack unit 94 is unitized by a back pack 92 forming a protection cover portion and a payout unit 93. Further, each control board is mounted with an MPU as a one-chip microcomputer that controls 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.

[0064] 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 substrate boxes 100 to 104. The substrate boxes 100 to 104 include a box base and a box cover that covers 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 substrate.

[0065] Further, the substrate box 100 (main control device 110) and the substrate box 102 (payout control device 111 and launch 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 part 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 know whether the substrate boxes 100 and 102 have been opened.

[0066] 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, a case rail 132 that is vertically connected to 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 according to a predetermined electrical configuration of a payout motor 216 (see FIG. 4). Balls supplied from the island equipment in the game hall are sequentially replenished in the tank 130, and the payout device 133 appropriately pays out the required number of balls. A vibrator 134 for applying vibration to the tank rail 131 is attached to the tank rail 131.

[0067] 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 launch control device 112, and a RAM erase switch 122 is provided in the power supply device 115. The state return switch 120 is operated, for example, 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 launch force of the launch 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.

[0068] Next, with reference 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.

[0069] The main control device 110 is equipped with an MPU 201 as a one-chip microcomputer which is an arithmetic device. The MPU 201 includes 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 etc. 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 main processes of the pachinko machine 10 such as jackpot lottery, setting of displays in the first symbol display devices 37A, 37B, the segment display device 600, and the decorative symbol display device 800, and lottery of display results in the second symbol display device.

[0070] 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.

[0071] 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 such that backup voltage is supplied from the power supply device 115 even after the power of the pachinko machine 10 is cut off, and data can be held (backed up), and all data stored in the RAM 203 is backed up.

[0072] 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 the 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, an NMI interrupt process (not shown) as a process at the time of power failure is immediately executed.

[0073] 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, a voice 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 large opening solenoid for driving the opening and closing plate of the specific winning port 65a to open and close forward about the lower side as an axis, and solenoids for driving electric accessories. The MPU 201 transmits various commands and control signals to these via the input / output port 205.

[0074] Also, connected to the input / output port 205 are various switches 208 including a switch group (not shown), 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.

[0075] 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.

[0076] Similar to the RAM 203 of the main control device 110, the RAM 213 of the payout control device 111 has a stack area that stores the contents of the internal registers of the MPU 211 and the return destination addresses of the control programs executed by the MPU 211, and a work area (working area) that stores various flags, counters, values of I / O, etc. The RAM 213 is configured such that backup voltage is supplied from the power supply device 115 even after the power of the pachinko machine 10 is cut off, and the data stored in the RAM 213 can be held (backed up). 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 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.

[0077] 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. 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.

[0078] 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 satisfied. Specifically, the touch sensor 51a detects that the player is touching the operation handle 51, and on the condition that the launch stop switch 51b for stopping the launch of the ball 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.

[0079] The audio lamp control device 113 controls the output of audio from an audio output device (such as a speaker not shown) 226, the lighting and extinguishing outputs of a lamp display device (such as the electric decoration parts 29 to 33 and the display lamp 34) 227, and the setting of the display modes of the segment display device 600 and the decorative pattern display device 800 performed by the display control device 114 such as variable effects (variable displays) and preview effects. The MPU 221 which is an arithmetic device has a ROM 222 storing control programs, fixed value data, etc. executed by the MPU 221, and a RAM 223 used as a work memory, etc.

[0080] An input / output port 225 is connected to the MPU 221 of the audio 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 audio 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 KM1, KM2, and KM3.

[0081] The voice lamp control device 113 determines the display modes of the segment display device 600 and the decorative pattern display device 800 based on various commands (such as a variation pattern command, a stop type command, etc.) received from the main control device 110, and notifies the display control device 114 of the determined display modes by commands (such as a display variation pattern command, a display stop type command, etc.). 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 mode displayed on the segment display device 600 and the decorative pattern display device 800, or to change the production content during super reach. When the displayed mode is changed, a back image change command including information on the changed displayed mode is transmitted to the display control device 114 so as to cause the segment display device 600 and the decorative pattern display device 800 to display decorations corresponding to the changed displayed mode. Here, the back image is an image displayed on the back side of the third symbol, which is the main image to be displayed on the segment display device 600 and the decorative pattern display device 800. The display control device 114 displays various decorations on the segment display device 600 and the decorative pattern display device 800 according to the commands transmitted from this voice lamp control device 113.

[0082] Further, the voice lamp control device 113 receives commands (display commands) representing the display contents of the segment display device 600 and the decorative pattern display device 800 from the display control device 114. Based on the display commands received from the display control device 114, the voice lamp control device 113 outputs, from the voice output device 226, voices corresponding to the display contents in accordance with the display contents of the segment display device 600 and the decorative pattern display device 800, and controls the lighting and extinguishing of the lamp display device 227 corresponding to the display contents.

[0083] The display control device 114 is connected to the voice lamp control device 113, the segment display device 600, and the decorative pattern display device 800, and controls displays such as the variation effect of the third pattern in the segment display device 600 and the decorative pattern display device 800 based on the commands received from the voice lamp control device 113. Further, the display control device 114 appropriately transmits a display command for notifying the display contents of the segment display device 600 and the decorative pattern display device 800 to the voice lamp control device 113. The voice lamp control device 113 outputs voice from the voice output device 226 in accordance with the display contents indicated by this display command, so that the display of the segment display device 600 and the decorative pattern display device 800 can be synchronized with the voice output from the voice output device 226.

[0084] 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 these 12-volt voltage, 5-volt voltage, and backup voltage to the control devices 110 to 114 and the like as necessary voltages.

[0085] The power failure monitoring circuit 252 is a circuit for outputting a power failure 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 failure or the like. The power failure monitoring circuit 252 monitors the voltage of the DC stabilized 24 volts, which is the maximum voltage output from the power supply unit 251. When this voltage becomes less than 22 volts, it determines that a power failure (power cut, power supply cut-off) has occurred and outputs the power failure signal SG1 to the main control device 110 and the payout control device 111. By the output of the power failure signal SG1, the main control device 110 and the payout control device 111 recognize the occurrence of a power failure and execute NMI interrupt processing. Note that even after the voltage of the DC stabilized 24 volts becomes less than 22 volts, the power supply unit 251 is configured to maintain the output of the 5-volt voltage, which is the drive voltage of the control system, at a normal value for a sufficient time for the execution of 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).

[0086] 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 when the pachinko machine 10 is powered on, 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.

[0087] Next, with reference to FIG. 5, the schematic configuration of the game board 13 will be described. FIG. 5 is an exploded perspective front view of the game board 13. In FIG. 13, a state in which the winning port unit 500 is disassembled from the game board 13 is shown.

[0088] As shown in FIG. 5, the winning port unit 500 is inserted and disposed from the front side into an opening 13a formed below the game area partitioned by two rails 76 and 77 planted on the front surface of the game board 13 and a resin outer edge member 73 connecting between the rails. The detailed configuration of the winning port unit 500 will be described later.

[0089] Next, with reference to FIGS. 6 to 9, the schematic configuration of the operation unit 300 will be described. FIG. 6 is a perspective front view of the operation unit 300. FIG. 7 is an exploded perspective front view of the operation unit 300. FIGS. 8 and 9 are front views of the operation unit 300.

[0090] In FIG. 8, a state in which displacement members 670 arranged in a pair above and below the segment display device 600 are respectively retracted to the upper and lower sides is illustrated, and in FIG. 9, a state in which the displacement members 670 arranged in a pair above and below the segment display device 600 protrude to the upper and lower central positions from the mode shown in FIG. 8 is illustrated.

[0091] As shown in FIGS. 6 and 7, the operation unit 300 includes a rear case 400 formed in a box shape, and a decorative pattern display device 800, a segment display device 600, and a decoration unit 700 are accommodated in the internal space of the rear case 400.

[0092] The rear case 400 includes a bottom wall portion 401 that is substantially rectangular in a front view, and outer wall portions 402 that are erected from the outer edges of the four sides of the bottom wall portion 401 toward the front, and is formed in a box shape with one side (front side) opened by these wall portions 401 and 402. An opening 401a that is rectangular in a front view is formed at the center of the bottom wall portion 401, and the segment display device 600 is disposed from the back side of the rear case 400 through the opening 401a.

[0093] The decorative pattern display device 800 is arranged in three parallel rows in the left-right direction in the opening 401a of the bottom wall portion 401 of the rear case 400. The decorative pattern display device 800 is provided with an inner reel unit 810 and an outer reel unit 820 (see FIG. 31) that rotate and displace in the vertical direction, and is configured such that a pattern decorated on the outer peripheral surfaces of the inner reel unit 810 and the outer reel unit 820 fluctuates (rotates) in a manner visible to the player. A detailed description of the decorative pattern display device 800 will be given later.

[0094] The segment display device 600 is disposed on the bottom wall portion 401 of the rear case 400 and is configured to cover the decorative pattern display device 800. A predetermined gap is formed between the opposing sides of the base member 660 (see FIG. 49) of the decorative pattern display device 800, and the decorative pattern display device 800 is disposed between the gaps, so that the decorative pattern display device 800 can be visually recognized from the player side.

[0095] Further, a displacement member 670 (see FIG. 49) that can be displaced forward of the gap between the opposing sides of the base member 660 described above is disposed on the segment display device 600. By displacing the displacement member 670 in front of the decorative pattern display device 800, an effect form in which the decorative pattern display device 800 cannot be visually recognized from the player side can be formed. A detailed description of the segment display device 600 will be given later.

[0096] The decoration unit 700 is formed in a horizontally long rectangular box shape when viewed from the front and is disposed in a pair above and below the segment display device 600. The decoration unit 700 is formed of a transparent resin material, and its shape is formed in a shape imitating the logo or title of the pachinko machine 10. Further, an LED board that irradiates light is disposed inside the decoration unit 700, and it is formed so that light can be irradiated to the player side.

[0097] Next, with reference to FIGS. 10 to 29, a detailed description of the winning port unit 500 will be given. First, with reference to FIGS. 10 to 13, the configuration of the winning port unit 500 will be described.

FIG. 11 is an exploded perspective front view of the winning port unit 500, and FIG. 12 is an exploded perspective rear view of the winning port unit 500. FIG. 13 is an exploded perspective view of the base member 510 and the first electric accessory 520.

[0099] As shown in FIGS. 10 to 13, the winning port unit 500 is mainly formed of a base member 510 disposed on the front surface of the game board 13 (see FIG. 5), a first electric accessory 520 rotatably supported inside the base member 510, and a drive unit 530 that applies a driving force to the first electric accessory 520.

[0100] The base member 510 is formed by fastening a front base 511 disposed on the front side and a rear base 512 disposed at a predetermined interval from the front base 511.

[0101] The front base 511 is formed of a plate-like body having a horizontally long rectangular shape when viewed from the front and is formed of a transparent resin material. The front base 511 mainly includes a first protruding portion 511a protruding from the upper end portion of the central portion in the left-right direction to the rear side, a second protruding portion 511b protruding from the lower end portion to the rear side at the central portion in the left-right direction, and a third protruding portion 511c protruding at a position separated from the second protruding portion 511b by a predetermined gap in the left-right direction.

[0102] Also, the front base 511 is disposed at a position where its front surface is visible from the player side, and a pattern is formed on the front side by unevenness.

[0103] The first protruding portion 511a is a plate member for preventing a game ball from being fed into a second winning port 140 formed in the rear base 512 when the first electric accessory 520 described later is in a closed state (a state where the tips of the wing members 520L and 520R are located above the rotation axis (shaft member JB1)).

[0104] That is, the first protruding portion 511a is formed above the space between the pair of wing members 520L and 520R in the closed state, and the distance between the first electric accessory 520 and the first protruding portion 511a is set to be smaller than the diameter of the game ball.

[0105] Further, the upper surface of the first protruding portion 511a is formed to be inclined downward from a substantially central position in the left - right direction toward both left and right ends. Thereby, the game ball fed to the upper part of the first protruding portion 511a can be made to roll on its upper surface and fall (flow down) downward.

[0106] The second protruding portion 511b is formed to protrude in a horizontally long rectangular shape from the back side of the front base 511, and the vertical position of its upper end surface is set to be lower than the bottom surface of the second winning port 140 of the back base 512. Further, the second protruding portion 511b is mainly formed with a standing portion 511b1 standing in front of the second winning port 140 of the back base 512, engaging portions 511b2 protruding from both left and right ends of the standing portion 511b1, and a recessed portion 511b3 recessed in the bottom surface portion.

[0107] Also, a base member 511f provided with an LED that irradiates light downward is disposed below the standing portion 511b1 of the second protruding portion 511b. The LED of the base member 511f is disposed in a manner of irradiating light upward. Thus, the periphery of the second winning port 140 can be made to emit light by the LED.

[0108] The standing portion 511b1 is formed to stand upward from the upper end of the second protruding portion 511b, two are arranged side by side in the left - right direction, and their standing tips are connected. Also, the upper surface of the standing portion 511b1 is formed to be inclined downward toward the second winning port 140 (back side), and the vertical position of the end portion on the second winning port 140 side is set to the same height as the bottom surface of the second winning port 140. Thus, the game ball fed to the upper part of the standing portion 511b1 can be made to roll toward the second winning port 140 side. Therefore, the game ball fed to the upper part of the standing portion 511b1 can enter the second winning port 140.

[0109] In addition, the connecting portion of the standing portions 511b1 arranged side by side is formed in a shape in which the central position in the circumferential direction is recessed downward. As a result, the game balls fed to the upper part of the standing portion 511b1 can easily stay at the central position in the left-right direction of the standing portion 511b1. Therefore, the rolling direction of the game balls fed to the upper part of the standing portion 511b1 can be quickly switched to the side of the second winning opening 140. As a result, it is possible to prevent the game balls fed to the upper part of the standing portion 511b1 from colliding with the game balls fed later and being pushed out to the outside, and it is easy to let the game balls enter the second winning opening 140.

[0110] The engaging portion 511b2 is a portion that engages with the left and right wing members 520L and 520R described later, and is formed to protrude from both the left and right sides of the base end portion of the standing portion 511b1 toward the center of the shaft support portion 511d described later.

[0111] The recessed portion 511b3 is a recess for forming a space for inserting a driver when fastening the front base 511 and the rear base 512. As a result, a screw can be inserted into a through hole 511b4 formed through the side surface on the back side of the recessed portion 511b3.

[0112] The third protruding portion 511c is a plate member that rolls a game ball to the first out port 71 formed in the rear base 512, and is formed adjacent to both outer sides in the left-right direction of the first out port 71 formed at two locations with the second winning opening 140 interposed therebetween in the rear base 512. In other words, the third protruding portion 511c is formed at a position spaced apart in the left-right direction by the dimensions of the second protruding portion 511b and the first out port 71 in the left-right direction.

[0113] The bottom surfaces of the third protruding portions 511c are each inclined downward toward the adjacent first out port 71 side (toward the center side in the left-right direction of the front base 511 (the left-right direction in FIG. 10(a))), and the lowermost position is set higher than the bottom surface of the first out port 71. Therefore, the game balls fed to the upper part of the third protruding portion 511c can be rolled toward the first out port 71 and made to enter the first out port 71.

[0114] The shaft support 511d is formed to project annularly from the back side of the front base 511, and two are formed at the same height in the vertical direction (the vertical direction in FIG. 10(a)) with the standing portion 511b1 interposed therebetween. The inner diameter of the shaft support 511d is formed larger than the diameter of the shaft member JB1 described later. Therefore, the shaft member JB1 can be inserted into the shaft support 511d.

[0115] The back base 512 is formed from a horizontally long rectangular plate-like body having a larger front view shape than the front base 511 in a front view. Therefore, the player can directly visually recognize the front surface of the back base 512 in a portion that does not overlap with the front base 511 in the front-rear direction.

[0116] Also, since the front base 511 is formed of a transparent material, in a portion where the front base 511 overlaps in front, the back base 512 can be visually recognized through the front base 511. Furthermore, the player can visually recognize the game balls fed between the facing surfaces of the back base 512 and the front base 511 through the front base 511.

[0117] The back base 512 is mainly formed with a first winning port 64 formed at the upper end portion on the front side, a second winning port 140 formed below the first winning port 64, first out ports 71 formed on both adjacent sides of the second winning port 140, and a general winning port 63 formed above the first out port 71 on the right side in a front view.

[0118] The first winning port 64 is recessed downward from the upper end portion at a substantially central position in the left-right direction (the left-right direction in FIG. 10(a)) of the front base 511, and projects in both the front and rear directions along the recessed edge portion. Also, the protruding tip on the front side (the front side of the paper surface in FIG. 10(a)) is blocked by a plate member.

[0119] The recessed shape of the first winning port 64 is formed to have a size through which a game ball can pass inside, and its bottom surface (the inner surface on the lower side in the direction of gravity) is inclined toward the back side. Thereby, the game ball that has entered the first winning port 64 can be fed to the back side of the game board 13.

[0120] The second winning port 140 is formed to penetrate downward in the gravitational direction of the first winning port 64 (the lower side in FIG. 10(a)). The second winning port 140 is formed to penetrate in a square shape with a dimension larger than the diameter of the game ball in a front view. Therefore, the game ball can be fed to the back side of the game board 13 through the second winning port 140. Further, the second winning port 140 is provided with recesses 140a recessed in the left and right inner side surfaces.

[0121] The recesses 140a are recessed in a curved shape centered on the axis of the shaft hole 512a. Thereby, the protrusions 523L and 523R of the left and right wing members 520L and 520R described later can be accommodated inside. That is, inside the second winning port 140, the game ball can pass through, and the protrusions 523L and 523R are in a state of being inserted.

[0122] The shaft holes 512a are recessed from the front to the back on both the left and right sides of the second winning port 140 of the back base 512. The shaft holes 512a are grooves for inserting a shaft member JB1 described later, and are formed in a circular shape with a diameter larger than the diameter of the shaft member JB1.

[0123] The first out port 71 is formed to penetrate on both the left and right sides of the second winning port 140. The first out port 71 is a hole for collecting the game balls that have flowed down in the game area formed on the front surface of the game board 13, and is formed in a horizontally long rectangle in a front view, and the width dimension in its vertical direction (short side direction) is set to be larger than the diameter of the game ball. Further, the bottom surface (the inner surface on the lower side in the gravitational direction) of the first out port 71 is formed to be inclined toward the back side. Therefore, the game balls that have entered the first out port 71 can be fed to the back side of the game board 13.

[0124] A guide wall 512b that protrudes forward by connecting to the bottom surface is formed in the first out port 71. The guide wall 512b is a member for receiving the game balls that have flowed down in the game area on its upper surface and feeding them to the first out port 71, and its upper surface is formed to be inclined downward toward the back side.

[0125] In addition, a plurality of ribs extending in the front-rear direction are arranged side by side on the bottom surface (lower surface) of the guide wall 512b. Thereby, the rigidity of the guide wall 512b can be improved. As a result, when the game ball flowing down the game area collides with the upper surface of the guide wall 512b, it is possible to suppress the guide wall 512b from being damaged.

[0126] The fastening between the front base 511 and the rear base 512 is performed by the above-described through-hole 511b4 and a fastening hole 512c formed through the rear base 512 at a position corresponding to the through-hole 511b4. That is, in a state where the front base 511 and the rear base 512 are combined in the front-rear direction, a driver is inserted into the recessed portion 511b3 from the lower side of the front base 511, and a screw is fastened to the fastening hole 512c through the through-hole 511b4.

[0127] The first electric accessory 520 is formed as a unit including a left wing member 520L disposed on the left side in a front view of the second winning port 140 and a right wing member 520R disposed on the right side in the front view.

[0128] Note that the left wing member 520L and the right wing member 520R are different only in the positions of the bulging portions 524L and 524R described later, and other members are formed symmetrically with respect to the second winning port 140. Therefore, except for the bulging portions 524L and 524R, only the left wing member 520L will be described, and a detailed description of the right wing member 520R will be omitted.

[0129] In addition, the left wing member 520L and the right wing member 520R can be displaced between a first state (closed state) in which the corner portion on the far side from the through-hole 521L is positioned above in the gravitational direction and a second state (open state) in which the corner portion on the far side from the through-hole 521L is displaced to a position separated from the outer side in the left-right direction of the second winning port 140 by driving the solenoid 531 of the drive unit 530 described later. Unless otherwise specified, the first state will be described. Also, in the first state, the opposing side surfaces of the left and right wing members 520L and 520R will be described with reference numerals 526L and 526R for the side surfaces.

[0130] The left vane member 520L is formed in a substantially triangular shape in a front view and has a dimension larger than the diameter of the game ball in the front-rear direction. The left vane member 520L has, at the lower end portion in the direction of gravity, a through hole 521L penetrating in the front-rear direction, a recess 522L recessed from the front side to the back side around the through hole 521L, a protrusion 523L protruding from the vicinity of the through hole 521L to the back side, a recessed portion 525L recessed in the radial direction of the through hole 521L on the end face on the side of the through hole 521L, a bulging portion 524L protruding from the side face 526L, and a shaft member JB1 inserted into the through hole 521L. A detailed description of the bulging portion 524L will be given later.

[0131] The shaft member JB1 is a columnar rod member formed of a metal material. The shaft member JB1 is a shaft that rotatably holds the left and right vane members 520L and 520R, and is formed with an outer diameter smaller than the inner diameter of the through hole 521L.

[0132] Also, the shaft member JB1 is formed such that the length in its axial direction is substantially the same as or slightly shorter than the separation distance from the recessed end face of the shaft hole 512a to the back side of the front base 511. Therefore, when assembling the front base 511 and the back base 512, one end (the end on the side of the back base 512) of the shaft member JB1 is inserted into the inside of the shaft hole 512a, and the other side (the end on the side of the front base 511) is inserted into the inside of the shaft support portion 511d, so that the shaft member JB1 can be held between the front base 511 and the back base 512.

[0133] The left vane member 520L is set such that the dimension in the front-rear direction is smaller than the distance dimension between the front base 511 and the back base 512 facing each other. Therefore, when assembling the front base 511 and the back base 512, by inserting the shaft member JB1 through the through hole 521L, the vane member 520L can be rotatably held between the front base 511 and the back base 512.

[0134] The recessed portion 522L is formed by being recessed from the front side around the axis of the through-hole 521L, and the recessed dimension is set to be smaller than the protruding distance of the shaft support portion 511d. Further, the distance dimension from the axis of the through-hole 521L to the inner peripheral surface of the recessed portion 522L is set to be larger than the radius dimension of the outer peripheral surface from the axis of the shaft support portion 511d.

[0135] Therefore, when the blade member 520L is disposed between the front base 511 and the rear base 512, it is possible to suppress the front surface of the blade member 520L and the rear surface of the front base 511 from being grounded, and the grounding portion between the blade member 520L and the front base 511 can be made the recessed portion 522L and the shaft support portion 511d. Therefore, the grounding between the blade member 520L and the front base 511 can be made partial. As a result, when the blade member 520L is rotated by the drive of a solenoid 531 described later, the resistance acting on the blade member 520L can be reduced and the blade member 520L can be easily rotated.

[0136] In addition, since the shaft support portion 511d can be housed inside the recessed portion 522L, the distance dimension between the front base 511 and the rear base 512 can be reduced. As a result, the distance dimension in the front-rear direction of the winning port unit 500 can be reduced.

[0137] Here, conventionally, there has been a gaming machine in which a shaft member JB1 is fitted inside the through-hole 521L of the blade member 520L.

[0138] However, in the conventional gaming machine, in order to fit the shaft member JB1 inside the through-hole 521L, when the blade member 520L is damaged, it is necessary to replace the blade member 520L and the shaft member JB1 during parts replacement. Therefore, there has been a problem that the parts cost becomes high.

[0139] On the other hand, in the present embodiment, the shaft member JB1 is only inserted into the inside of the through-hole 521L formed in the blade member 520L, and the blade member 520L and the shaft member JB1 can be disposed in the winning port unit 500 as separate bodies. Therefore, the replacement part when the blade member 520L is damaged can be only the blade member 520L. As a result, it is possible to suppress an increase in the parts cost.

[0140] Also, as described above, the fastening of the front base 511 to the rear base 512 can be performed from the front side of the front base 511. Therefore, when the wing member 520L is damaged, the front base 511 can be removed from the rear base 512 with the winning port unit 500 attached to the game board 13. As a result, the replacement of the wing member 520L can be easily performed.

[0141] That is, when removing the front base 511 from the rear side of the rear base 512, it is necessary to remove the winning port unit 500 from the game board 13 before removing the front base 511 from the rear base 512. However, since the front base 511 is formed to be removable from the front side, the front base 511 can be easily removed. As a result, the replacement of the wing member 520L can be easily performed.

[0142] Here, if the front base 511 is made removable from the front side of the rear base 512, the heads of screws or the like for fastening the front base 511 and the rear base 512 become visible from the player's side (front side), and there is a risk that the player's interest may be impaired by the player visually recognizing the heads of the screws for fastening the front base 511 and the rear base 512.

[0143] In contrast, in the present embodiment, the fastening between the front base 511 and the rear base 512 is performed using the space of the recessed portion 511b3 formed in the front base 511. That is, by inserting a driver obliquely into the recessed portion 511b3 from the lower side of the front base 511, a screw can be fastened to the fastening hole 512c through the through hole 511b4. Therefore, even when the front base 511 is positioned on the front side of the through hole 511b4, the front base 511 and the rear base 512 can be fastened by inserting a driver obliquely into the recessed portion 511b3. Accordingly, the head of a screw or the like for fastening the front base 511 and the rear base 512 can be made difficult to be visually recognized from the player side (front side). As a result, it is possible to suppress the player's interest from being impaired by visually recognizing the head of the screw that fastens the front base 511 and the rear base 512.

[0144] Also, normally, the decorative symbol display device 800 and the segment display device 600 that can be visually recognized through the opening formed in the central portion of the game board 13 are set at the height of the player's line of sight. Therefore, the winning port unit 500 is disposed below the height of the player's line of sight. As a result, it is possible to make it difficult to visually recognize the head of the screw that fastens the front base 511 and the rear base 512 from the player side, and it is possible to suppress the player's interest from being impaired by visually recognizing the head of the screw that fastens the front base 511 and the rear base 512.

[0145] Note that since the front base 511 is formed of a transparent resin material, the head of the screw can be visually recognized through the front base 511. However, as described above, unevenness and patterns are formed on the front side of the front base 511, so light can be emitted in other directions due to differences in the thickness of the plate. Thereby, the head of the screw that can be visually recognized through the front base 511 can be blurred. As a result, it is possible to suppress the player's interest from being impaired.

[0146] Next, with reference to FIGS. 14 to 16, a detailed description of the drive unit 530 will be given. FIG. 14 is an exploded perspective front view of the drive unit 530. FIGS. 15(a) and 15(b) are side views of the drive unit 530 and the first electric component 520. FIGS. 16(a) and 16(b) are front views of the drive unit 530 and the first electric component 520.

[0147] Note that FIGS. 15(a) and 16(a) illustrate the state where the first electric component 520 is located in the first state, and FIGS. 15(b) and 16(b) illustrate the state where the first electric component 520 is located in the second state.

[0148] As shown in FIG. 14, the drive unit 530 mainly includes a solenoid 531, a sliding member 532 connected to the solenoid 531, a rotating member 533 connected to the sliding member 532, a first case member 534 in which the rotating member 533 and the sliding member 532 are disposed so as to be displaceable therein, and a second case member 536 attached to the back side of the first case member 534.

[0149] The solenoid 531 mainly includes a main body portion 531a having an electric wire therein and generating an electromagnetic force when electric power is passed through the electric wire, a movable body 531b slidably disposed inside the main body portion, and an engaging portion 531c attached to the tip of the movable body.

[0150] The main body portion 531a is formed in a prismatic shape that is long in the front-rear direction, and an electric wire is disposed therein. On the front side of the main body portion 531a, a recess is formed that is recessed on the back side, and a movable body 531b formed in a cylindrical shape is disposed inside the recess.

[0151] The movable body 531b is formed of a metal material and can slide on the back side (inside the main body portion 531a) by applying electric power to the electric wire of the main body portion 531a to generate an electromagnetic force.

[0152] The engaging portion 531c is attached to the end of the movable body 531b on the side opposite to the main body portion 531a. The engaging portion 531c is formed in a disk shape with an outer diameter larger than the outer diameter of the movable body 531b, and its axis is positioned and arranged substantially in the same line as the axis of the movable body 531b.

[0153] The engaging portion 531c is inserted into the engaging groove 532a2 of the sliding member 532 described later. Thereby, as the movable body 531b is displaced, the sliding member 532 can be displaced in the front-rear direction (the left-right direction in Fig. 15(a)).

[0154] The sliding member 532 is formed in a substantially E shape in a top view, and mainly includes a connecting portion 532a extending in the left-right direction, two first protrusions 532b protruding from both left and right ends of the connecting portion 532a to the front side, and a second protrusion 532c located in the middle of the two first protrusions 532b and protruding to the front side.

[0155] The sliding member 532 is formed such that the dimension of the connecting portion 532a in the left-right direction is smaller than the opposing dimension in the left-right direction on the inner peripheral surface of the first case member 534 described later. Thereby, the sliding member 532 can be accommodated and arranged inside the first case member 534.

[0156] The connecting portion 532a is mainly formed with a recess 532a1 recessed on the back side, an engaging groove 532a2 connected to the front side of the recess 532a1 and recessed from the upper side, and cut portions 532a3 formed on both left and right sides at the base end of the second protrusion 532c.

[0157] As described above, the recess 532a1 is a recess that suppresses the contact of the movable body 531b of the solenoid 531 with the connecting portion 532a when the engaging portion 531c of the solenoid 531 is inserted into the engaging groove 532a2. That is, the recess 532a1 is formed in an arc shape whose recessed surface is larger than the outer diameter of the movable body 531b. Thereby, the contact of the movable body 531b of the solenoid 531 with the connecting portion 532a can be suppressed.

[0158] The engaging groove 532a2 is formed by connecting to the front side of the concave portion 532a1, and the recessed depth from the upper surface side in the direction of gravity is set to be larger than the diameter of the engaging portion 531c. Further, the engaging groove 532a2 is set such that the width dimension in the left - right direction is larger than the diameter of the engaging portion 531c, and the width dimension in the front - rear direction is formed to be substantially the same as or larger than the thickness dimension of the engaging portion 531c in the front - rear direction. Therefore, the engaging portion 531c can be inserted inside the engaging groove 532a2.

[0159] The cut - in portion 532a3 is a notch for easily elastically deforming the sliding member 532 when connecting the first protrusion 532b (described later) to the rotating member 533, and is formed on both left and right sides of the base end of the second protrusion 532c as described above, and is cut in toward the back side.

[0160] The first protrusion 532b is provided with an engaging hole 532d penetrating in the left - right direction. The engaging hole 532d is formed in a long - hole shape that is long in the front - rear direction, and is mainly formed with a first opening 532d1 recessed downward in the direction of gravity from the front - side end and a second opening 532d2 recessed downward in the direction of gravity from the back - side end. Details of the first opening 532d1 and the second opening 532d2 will be described later.

[0161] The engaging hole 532d is set such that the width dimension in the up - down direction at the central portion in the front - rear direction (the portion other than the first opening 532d1 and the second opening 532d2) is larger than the width dimension of the protrusion 533b of the rotating member 533 (described later) in the up - down direction. Thereby, the protrusion 533b can be arranged inside the engaging hole 532d.

[0162] The second protrusion 532c is formed between the two first protrusions 532b as described above, and is formed to protrude forward. Further, the second protrusion 532c is provided with a standing wall 532c1 standing downward on the tip side opposite to the connecting portion 532a. Details of the standing wall 532c1 will be described later.

[0163] The rotating member 533 is formed by arranging two plate-like bodies formed in a substantially L shape in side view with a predetermined width therebetween in the left-right direction, and the opposing spaces on one end side are connected by a connecting portion 533a. The gap between the opposing surfaces of the two plate-like bodies of the rotating member 533 is set to be larger than the diameter of the game ball. Thus, the game ball can pass through the inside of the rotating member 533 (between the opposing surfaces of the two plate-like bodies).

[0164] Also, the width dimension of the rotating member 533 in the left-right direction (the dimension between the opposing surfaces of the outer surfaces of the two plate-like bodies) is set to be smaller than the dimension between the opposing surfaces inside the two first protrusions 532b of the sliding member 532. Thus, the rotating member 533 can be disposed between the opposing surfaces of the first protrusions 532b of the sliding member 532.

[0165] The rotating member 533 is mainly formed with a rotating shaft 533c protruding from both sides in the left-right direction from the bent portion of the substantially L shape in side view, a protrusion 533b protruding from both sides in the left-right direction from the end portion on one end side of the substantially L shape in side view, and a drive portion 533d formed by recessing at the tip of the other end side of the substantially L shape in side view.

[0166] The rotating shaft 533c protrudes from both the left and right outer sides of the rotating member 533, and the distance dimension between the protruding tip surfaces thereof is set to be substantially the same as the width dimension of the first case member 534 in the left-right direction. Also, the protruding dimension of the rotating shaft 533c is set to be larger than the thickness dimension of the first case member 534 in the left-right direction. Therefore, the rotating shaft 533c can be received inside the recess 534a of the first case member 534 described later, and by assembling the second case member 535 to the first case member 534, the rotating member 533 can be held rotatably with respect to the first case member 534 and the second case member 535.

[0167] The protrusion 533b is formed to protrude on both the left and right outer sides of the rotating member 533, and the distance dimension between the protruding tip surfaces thereof is set to be substantially the same as the distance dimension between the left and right outer side surfaces of the two first protrusions 532b of the sliding member 532. Further, the protruding dimension of the protrusion 533b is set to be larger than the width dimension of the first protrusion 532b in the left-right direction. Therefore, by inserting the protrusion 533b into the engagement hole 532d of the first protrusion 532b, the sliding member 532 and the rotating member 533 can be connected.

[0168] Note that the connection between the sliding member 532 and the rotating member 533 can be performed by elastically deforming the two first protrusions 532b of the sliding member 532 left and right to widen the space between the two first protrusions 532b. In this case, as described above, since the cut portion 532a3 is formed in the sliding member 532, it is possible to easily widen the space between the two first protrusions 532b. As a result, it is possible to easily connect the rotating member 533 and the sliding member 532.

[0169] Furthermore, the distance dimension between the opposing inner side surfaces of the first case member 534 in the left-right direction is set to be substantially the same as the distance dimension between the opposing outer side surfaces of the first protrusions 532b or slightly larger than the distance dimension between the opposing outer side surfaces of the first protrusions 532b. Thereby, in a state where the rotating member 533 and the sliding member 532 are arranged inside the first case member 534, it is possible to suppress the first protrusions 532b from elastically deforming outward in the left-right direction. As a result, it is possible to suppress the disconnection between the rotating member 533 and the sliding member 532.

[0170] The drive portion 533d is formed by being recessed from the front side toward the back side. The drive portion 533d can accommodate the protrusions 523L and 523R of the wing member 520L inside. That is, the drive portion 533d is set to have a dimension larger than the protrusions 523L and 523R in the vertical direction. By accommodating the protrusions 523L and 523R in the drive portion 533d, the first electric actuator 520 can be displaced between the first state and the second state as the drive portion 533d is displaced. A detailed description of the displacement of the first electric actuator 520 will be described later.

[0171] The first case member 534 is formed in a substantially square shape when viewed from the front with an open interior and is formed to extend in the front-rear direction. The first case member 534 has a notch formed at the lower side on the back side, and the second case member 535 can be disposed in the notch portion.

[0172] The first case member 534 is mainly formed with a recess 534a recessed on the front side in the notch portion on the back side and a standing portion 534b standing on the bottom surface on the inner peripheral side.

[0173] As described above, the recess 534a is a recess for accommodating the rotation shaft 533c of the rotating member 533 inside, and is recessed in a shape larger than the diameter of the rotation shaft 533c. Therefore, by assembling the second case member 535 to the first case member 534 with the rotation shaft 533c accommodated inside, the rotating member 533 can be disposed inside the first case member 534.

[0174] The standing portion 534b is set such that the lower inner peripheral surface of the second winning port 140 of the back base 512 and its standing tip surface are at the same height, extends to the back side, and is formed with a downward inclination. Thus, in a state where the drive unit 530 is disposed on the back of the back base 512, the game balls that have entered the second winning port 140 can be rolled on the upper surface of the standing portion 534b and sent to the second case member 535.

[0175] The second case member 535 is formed in a horizontally long rectangular shape when viewed from the front and is formed with a predetermined thickness on the back side. The second case member 535 is provided with a through hole 535a penetrating in the vertical direction.

[0176] The through hole 535a is formed with an inner diameter larger than the diameter of the game ball, and as described above, the game balls that have been rolled on the upper part of the standing portion 534b and sent to the second case member 535 can be sent downward through the through hole 535a. Thus, the game balls that have flowed down in the game area and entered the second winning port 140 can be recovered.

[0177] Next, with reference to FIGS. 15 and 16, the displacement of the first electric accessory 520 will be described.

[0178] As shown in FIGS. 15(a) and 16(a), in the state where the first electric actuator 520 is positioned in the first state, the movable body 531b of the solenoid 531 is disposed around the movable body 531b and is protruded to the front side (the left side in FIG. 15(a)) by the biasing force of a biasing spring (not shown) interposed between the main body portion 531a and the connecting portion 532a.

[0179] In this case, the protrusion 533b of the rotating member 533 is positioned on the back side (the second opening 532d2 side) of the engaging hole 532d. Further, the center of gravity of the rotating member 533 in side view is positioned between the driving portion 533d and the rotating shaft 533c. That is, a rotational force in the direction of pushing down the driving portion 533d is always applied to the rotating member 533 about the axis of the rotating shaft 533c.

[0180] Therefore, even when the protrusion 533b of the rotating member 533 is positioned on the back side (the second opening 533d2 side) of the engaging hole 532d, it can stay at its upper portion without being guided to the inside of the second opening 533d2 (below the engaging hole 532d (the lower side in FIG. 15(a))).

[0181] Further, since the driving portion 533d is pushed downwards, the protrusions 523L and 523R of the left and right blade members 520L and 520R accommodated inside the driving portion 533d are pushed downwards. As a result, the left and right blade members 520L and 520R are in a state where the corners on the far side from the through holes 521L and 521R are positioned above the through holes 521L and 521R (the first state (see FIG. 16(a))).

[0182] As shown in FIGS. 15(b) and 16(b), when power is applied to the main body portion 531a of the solenoid 531, the movable body 531b is drawn into the main body portion 531a by the electromagnetic force generated in the main body portion 531a.

[0183] Therefore, as the movable body 531b is displaced, the sliding member 532 connected to the tip side of the movable body 531b is slid and displaced rearward (the right side in FIG. 15(b)). As described above, the rotating member 533 is always in a state where a rotational force in the direction of pushing down the driving part 533d acts around the axis of the rotating shaft 533c. Therefore, the protrusion 533b accommodated inside the engaging hole 532d of the sliding member 532 slides inside without being caught by the proximal end portion of the second opening 533d2.

[0184] The protrusion 533b that slides inside the second opening 533d2 abuts against the end portion on the front side (the first opening 532d1 side) of the engaging hole 532d at the displacement end position of the movable body 531b and is displaced to the back side (the right side in FIG. 15(b)). In this case, since the protrusion 533b rotates and displaces around the axis of the rotating shaft 533c, the protrusion 533b can be accommodated inside the first opening 532d1. That is, the first opening 532d1 is formed in a shape corresponding to the displacement of the protrusion 533b.

[0185] Also, since the rotating member 533 rotates around the axis of the rotating shaft 533c, the driving part 533d can be displaced upward (the upper side in FIG. 15(b)). As a result, the blade member 520L is rotated around the axes of the through holes 521L and 521R, and the corner portions on the far side from the through holes 521L and 521R are displaced to the left and right outer sides (the second state (see FIG. 16(b))).

[0186] On the other hand, the displacement from the second state to the first state is performed by cutting off the power supply to the main body part 531a of the solenoid 531. As a result, the electromagnetic force generated in the main body part 531a disappears. Therefore, due to the biasing force of a biasing spring (not shown) disposed around the movable body 531b and interposed between the main body part 531a and the connecting part 532a, the movable body 531b protrudes to the front side (the left side in FIG. 15(a)). As a result, the first electric actuator 520 can be displaced to the position in the first state.

[0187] As described above, since the first opening 532d1 is formed in a shape corresponding to the displacement of the protrusion 533b, the recessed depth of the first opening 532d1 downward in the direction of gravity (the lower side in FIG. 15(b)) is formed deeper toward the back side (the right side in FIG. 15(b)).

[0188] As a result, when the first electric component 520 is displaced from the second state to the first state, the base end portion of the first opening 532d1 can be made to collide with the protrusion 533b of the rotating member 533, making it easier to displace the protrusion 533b in the direction of gravity.

[0189] Next, with reference to FIG. 17, the operation of the second protrusion 532c will be described. FIGS. 17(a) and 17(b) are cross-sectional views of the winning port unit 500 taken along line XVII-XVII of FIG. 10(a). Note that in FIG. 17(a), the first electric component 520 is positioned in the first state, and in FIG. 17(b), the state where the first electric component 520 is positioned in the second state is respectively illustrated.

[0190] As shown in FIG. 17(a), when the first electric component 520 is in the first state, the far corners of the through holes 521L, 521R of the left and right wing members 520L, 520R are arranged near the first protruding portion 511a. Thereby, when the first electric component 520 is in the first state, it is possible to suppress the flow-down of game balls between the left and right wing members 520L, 520R.

[0191] Also, as described above, the solenoid 531 is in a state where the movable body 531b protrudes from the inside of the main body portion 531a. Therefore, the sliding member 532 connected to the movable body 531b (engagement portion 531c) is in a state of being positioned on the front side (the left side in FIG. 17(a)). That is, the standing wall 532c1 of the second protrusion 532c is arranged near the second winning port 140.

[0192] In this case, the distance dimension L1 from the standing tip of the standing wall 532c1 (the end portion on the lower side in the direction of gravity (the lower side in FIG. 17(a))) to the upper end surface of the standing portion 534b formed in the first case member 534 is set to be smaller than the diameter of the game ball.

[0193] Thus, even when the first electric device 520 is damaged and the movable body 531b of the solenoid 531 protrudes forward, if a game ball can flow into the space between the left and right blade members 520L and 520R, it is possible to prevent the game ball from entering and rolling inside the second winning opening 140. That is, the game ball rolling on the standing portion 534b of the first case member 534 can be made to collide with the standing wall 532c1 of the sliding member 532, thereby stopping the rolling of the game ball. As a result, when the first electric device 520 is damaged, it is possible to suppress a situation where the store side is disadvantaged even if the player continues the game.

[0194] In addition, in the present embodiment, a sensor device SE1 for detecting that a game ball has entered the second winning opening 140 is disposed in the flow path of the game ball in the second case member 535. Therefore, in order to detect that the game ball has passed through the inside of the second winning opening 140, it is necessary to roll the game ball to the second case member 535. Therefore, by stopping the rolling of the game ball inside the first case member 534, it is possible to suppress the pachinko machine 10 from detecting that a game ball has entered the second winning opening 140.

[0195] On the other hand, as shown in FIG. 17(b), when the first electric device 520 is in the second state, the distal corners of the through holes 521L and 521R of the left and right blade members 520L and 520R are separated from the first protruding portion 511a more than in the first state, and the separated distance is made larger than the diameter of the game ball. As a result, the game ball flowing down in the game area can be received by the side surfaces 526L and 526R of the left and right blade members 520L and 520R and rolled to the second winning opening 140. That is, when the first electric device 520 is in the second state, it is easier to let a game ball enter the second winning opening 140.

[0196] Also, as described above, the solenoid 531 is in a state where the movable body 531b is retracted inside the main body portion 531a. Therefore, the sliding member 532 connected to the movable body 531b (engagement portion 531c) is in a state of being located on the back side (right side in FIG. 17(b)). That is, the standing wall 532c1 of the second protrusion 532c is arranged at a position separated from the second winning opening 140 more than in the first state.

[0197] In this case, the distance dimension L2 from the standing tip of the standing wall 532c1 (the end on the lower side in the direction of gravity (the lower side in FIG. 17(b))) to the upper end surface of the standing portion 534b formed on the first case member 534 is set to be larger than the diameter of the game ball.

[0198] Accordingly, when the first electric accessory 520 is in the second state, the left and right wing members 520L and 520R are displaced, so that the game balls flowing down in the game area can easily enter the second winning opening 140, and the game balls that have entered the second winning opening 140 can roll on the standing portion 534b formed on the first case member 534 and be fed to the second case member 535.

[0199] Furthermore, since the displacement direction of the standing wall 532c1 can slide and displace the standing wall 532c1 in a direction substantially coinciding with the rolling direction of the game ball entering the second winning opening 140, when the wing members 520L and 520R are damaged (or opened due to an illegal act), it is possible to prevent the game ball that has collided with and stopped on the standing wall 532c1 from being pushed out to the side opposite to the rolling direction due to the displacement of the standing wall 532c1. As a result, when the first electric accessory 520 is opened by driving the solenoid 531 and game balls can enter the second winning opening 140, it is possible to prevent the game balls from jamming at the second winning opening 140. As a result, when the first electric accessory 520 is in the open state, the game balls can be smoothly guided inside the second winning opening.

[0200] Next, with reference to FIGS. 18 and 19, a description will be given of the case where the first electric accessory 520 is displaced from the first state to the second state due to an illegal act by the player. FIGS. 18(a) and 18(b) are front views of the winning opening unit 500. FIGS. 19(a) and 19(b) are side views of the first electric accessory 520 and the drive unit 530.

[0201] In FIGS. 18(a) and 18(b), for ease of understanding, the front base 511 is shown as being transparently visible. Further, in FIG. 19(a), the first electric component 520 and the drive unit 530 in the first state are shown, and in FIG. 19(b), the state when only the first electric component 520 is displaced from the first state is shown.

[0202] As shown in FIGS. 18 and 19, when the first electric component 520 in the first state is forcibly displaced to the second state only by the player's improper act (cheating act), the protrusions 523L and 523R of the left and right wing members 520L and 520R are displaced inside the second opening 532d2 of the engagement hole 532d. That is, since a space where the protrusions 523L and 523R can be displaced is formed, it is possible to prevent the first electric component 520 from being damaged when the first electric component 520 is forcibly displaced.

[0203] Next, with reference to FIGS. 20(a) and 20(b), the displacement of the standing portion 523c1 when the first electric component 520 is displaced due to the player's improper act will be described. FIG. 20(a) is a cross-sectional view of the winning port unit 500 along the line XXa-XXa in FIG. 18(a), and FIG. 20(b) is a cross-sectional view of the winning port unit 500 along the line XXb-XXb in FIG. 18(b).

[0204] As shown in FIGS. 20(a) and 20(b), when the first electric component 520 in the first state is forcibly rotated by the player's biasing act, the positions of the solenoid 531 and the sliding member 532 of the drive unit 530 are not displaced, and only the first electric component 520 and the rotating member 533 are rotationally displaced.

[0205] As described above, when the first electric component 520 is located in the first state, the distance dimension L1 from the standing tip of the standing wall 532c1 (the end portion on the lower side in the gravity direction (the lower side in FIG. 20(a))) to the upper end surface of the standing portion 534b formed in the first case member 534 is set to be smaller than the diameter of the game ball.

[0206] Here, conventionally, there is known a gaming machine including a second winning opening 140 formed to allow a game ball to enter, a pair of wing members 520L and 520R disposed with the second winning opening 140 therebetween, drive means (solenoid 531) for applying a driving force to the pair of wing members 520L and 520R to open or close them, and regulating means that is arranged at a permitting position to permit the entry of the game ball into the second winning opening 140 when the pair of wing members 520L and 520R are opened by the driving force of the drive means (solenoid 531), and is arranged at a regulating position to regulate the entry of the game ball into the second winning opening 140 when the pair of wing members 520L and 520R are closed by the driving force of the drive means (solenoid 531).

[0207] However, in the above-described conventional gaming machine, since the displacement of the regulating means is not restricted, for example, after forcibly opening the pair of wing members 520L and 520R from the outside, the regulating means can be displaced from the regulating position to the permitting position, so there is a problem in that the effect of regulating the illegal entry of the game ball into the second winning opening 140 is insufficient.

[0208] On the other hand, according to the present embodiment, since the arrangement of the standing wall 532c1 can be maintained at the regulating position when the pair of wing members 520L and 520R are closed or when the pair of wing members 520L and 520R are opened from the outside, it is possible to suppress the standing wall 532c1 from being displaced to the permitting position. Therefore, it is easy to regulate the illegal entry of the game ball into the second winning opening 140.

[0209] That is, when the pair of blade members 520L and 520R are in the closed state or when the pair of blade members 520L and 520R are opened from the outside, the sliding member 532 is operated so that the distance dimension L3 from the standing tip of the standing wall 532c1 (the end on the lower side in the gravitational direction (lower side in FIG. 20(b))) to the upper end surface of the standing portion 534b formed in the first case member 534 is set to be smaller than the diameter of the game ball. Therefore, even if the first electric accessory 520 is made to be able to send a game ball to the second winning opening 140 due to the player's improper act, it is possible to suppress the game ball from entering and rolling inside the second winning opening 140. Thus, the game ball rolling on the standing portion 534b of the first case member 534 can be made to collide with the standing wall 532c1 of the sliding member 532 to stop the rolling of the game ball. As a result, when the first electric accessory 520 is brought into the second state (able to send a game ball to the second winning opening 140) due to the player's improper act, it is easy to regulate the game ball from illegally entering the second winning opening 140.

[0210] Also, in this case, since the standing wall 532c1 that makes it impossible for the game ball to enter the second winning opening 140 can be formed continuously with the sliding member 532 that displaces the pair of blade members 520L and 520R, a separate member for regulating illegal entry into the second winning opening 140 is not required. Thus, the number of parts can be reduced accordingly, and an increase in the manufacturing cost can be suppressed.

[0211] Next, referring to FIGS. 21 and 22, the case where the second protrusion 532c is further pushed in the back side when the first electric accessory 520 is brought into the second state due to the player's improper act will be described. FIGS. 21(a) and 21(b) are side views of the first electric accessory 520 and the drive unit 530. FIG. 22(a) is a partially enlarged side view of the drive unit 530 in the range XXIIa of FIG. 21(a), and FIG. 22(b) is a partially enlarged side view of the drive unit 530 in the range XXIIb of FIG. 21(b).

[0212] As shown in FIGS. 21 and 22, a protrusion 532d3 protruding from the inner surface on the front side (the left side in FIG. 22(a)) is formed inside the second opening 532d2. Further, a notch 533b1 is formed in the protrusion 533b of the rotating member 533, the outer peripheral surface of which is cut in a side view.

[0213] The protrusion 532d3 and the notch 533b1 are formed in corresponding shapes in terms of their outer diameters. That is, the protruding shape of the protrusion 532d3 in a side view and the cut shape of the notch 533b1 are made substantially the same.

[0214] Therefore, when the standing wall 532c1 (sliding member 532) is pushed into the back side from the state where only the first electric accessory 520 is in the second state as shown in FIGS. 21(a) and 22(a) due to an illegal act, the protrusion 532d3 is received inside the notch 533b1, and the displacement toward the back side of the standing wall 532c1 (sliding member 532) is restricted. As a result, when the first electric accessory 520 is brought into the second state due to an illegal act by a player, it is possible to suppress the game ball from entering the second winning opening 140 and rolling on the standing portion 534b of the first case member 534 to be fed.

[0215] Further, in the present embodiment, one surface of the side surface of the protrusion 532d3 is formed to be inclined toward the back side upward (see FIG. 22(a)). Thereby, when the protrusion 532d3 is inserted inside the notch 533b1, it is possible to make it difficult for the protrusion 532d3 to come out of the notch 533b1.

[0216] That is, since the side surface of the protrusion 532d3 is inclined upward toward the back side, when a force is applied to further push the standing wall 532c1 (sliding member 532) toward the back side with the protrusion 532d3 inserted into the notch 532b1, the direction of the force acting on the contact surface between the protrusion 532d3 and the notch 532b1 can be set to the direction in which the protrusion 532d3 enters the inside of the notch 532b1. Therefore, when the protrusion 532d3 is inserted into the inside of the notch 533b1, it is possible to make it difficult for the protrusion 532d3 to come out of the notch 533b1. As a result, when the first electric game device 520 is brought into the second state due to an illegal act of the player, it is possible to reliably suppress the game ball from entering the second winning opening 140 and rolling on the standing portion 534b of the first case member 534 and being fed.

[0217] In other words, a transmission mechanism that transmits the driving force of the driving means (solenoid 531) to the pair of blade members 520L and 520R is provided. The transmission mechanism includes a sliding member 532 that is slidably displaced between an open slide position (the position shown in FIG. 17(b)) and a closed slide position (the position shown in FIG. 17(a)) by the driving force of the driving means (solenoid 531), and a rotation member 533 that is rotated to the open rotation position by the sliding displacement of the sliding member 532 to the open slide position to open the pair of blade members 520L and 520R and is rotated to the closed rotation position by the sliding displacement of the sliding member 532 to the closed slide position to close the pair of blade members 520L and 520R. The standing wall 532c1 is disposed on the sliding member 532. When the sliding member 532 is slidably displaced to the open slide position, the standing wall 532c1 is disposed at the allowable position, and when the sliding member 532 is slidably displaced to the closed slide position, the standing wall 532c1 is disposed at the restricted position. When the rotation member 533 is disposed at the open rotation position with the sliding member 532 disposed at the closed slide position, the rotation member 533 and the sliding member 532 are engaged with each other, so that the sliding displacement of the sliding member 532 to the open slide position is restricted, and it is easy to restrict the illegal entry of the game ball into the second winning opening 140.

[0218] That is, when a pair of blade members 520L and 520R that are closed are illegally forced to open from the outside, the rotating member 533 is rotated to the open rotation position while the sliding member 532 is disposed at the closed slide position. In such a state, since the rotation member 533 and the sliding member 532 are engaged with each other, the slide displacement of the sliding member 532 to the open slide position is restricted, so that the restricting means can be maintained at the restricting position (it is possible to prevent the restricting means from being illegally forced to displace to the allowable position from the outside). As a result, even if the pair of blade members 520L and 520R are forced to open from the outside and a game ball passes between the pair of blade members 520L and 520R, the restricting means can restrict the game ball from entering the second winning port 140.

[0219] Further, an engaging hole 532d is extended in one of the sliding member 532 and the rotating member 533, and a protrusion 533b protrudes from the other. As the protrusion 533b slides along the engaging hole 532d, the slide displacement of the sliding member 532 is transmitted to rotate the rotating member 533. At the same time, since the protrusion 533b is engaged with the inner wall surface of the engaging hole 532d, the slide displacement of the sliding member 532 to the open slide position is restricted, so that it is possible to make it difficult to release the restriction while achieving miniaturization.

[0220] That is, by using the engaging hole 532d and the protrusion 533b for transmitting the slide displacement of the sliding member 532 to the rotating member 533 to rotate it, a means for restricting the slide displacement of the sliding member 532 to the open slide position can be formed, and it is not necessary to separately provide such means at another location. Therefore, miniaturization can be achieved accordingly. Further, by adopting a structure in which the protrusion 533b is engaged with the inner wall surface of the engaging hole 532d, it is possible to make it difficult for an external illegal access to the engaging portion, and accordingly, it is possible to make it difficult to release the restriction (engagement).

[0221] Next, with reference to FIGS. 23 and 24, the bulging portions 524L and 524R of the left and right blade members 520L and 520R will be described in detail. FIG. 23(a) is a front perspective view of the left blade member 520L, and FIG. 23(b) is a front perspective view of the right blade member 520R. FIG. 24(a) is a front view of the winning port unit 500, and FIG. 24(b) is a cross-sectional view of the winning port unit 500 taken along line XXIVb-XXIVb in FIG. 24(a).

[0222] In FIGS. 23(a) and 23(b), the left-right direction when viewed obliquely is reversed between FIG. 23(a) and FIG. 23(b). Also, in FIG. 24(a), the front base 511 is shown in a transparent view. Further, in FIG. 24(b), the front base 511 that was shown in a transparent view in FIG. 24(a) is shown as opaque. Also, in FIG. 24(b), the rolling direction of the game balls rolling on the side surfaces 526L and 526R is shown by a two-dot chain line together with the symbol of the virtual line KS1. Further, the front direction of the virtual line KS1 is shown by an arrow F, and the back direction is shown by an arrow B.

[0223] As shown in FIGS. 23 and 24, the bulging portion 524L formed on the side surface 526L of the left blade member 520L is formed at the end on the side of the through hole 521L and is formed continuously with the end surface on the front side (arrow F side in FIG. 24(b)). On the other hand, the bulging portion 524R formed on the side surface 526R of the right blade member 520R is formed at the end on the side of the through hole 521R and is formed continuously with the end surface on the back side (arrow B side in FIG. 24(b)).

[0224] That is, the bulging portion 524L of the left blade member 520L and the bulging portion 524R of the right blade member 520R are formed at different positions in the front-rear direction (see FIG. 24(b)).

[0225] Further, on the side surfaces 526L and 526R, a first region that extends continuously from the tip side to the base end side of the blade members 520L and 520R is formed, and bulging portions 524L and 524R that are sized so as not to contact the game balls guided in the first region are formed. Also, the first regions of the side surfaces 526L and 526R of one of the pair of blade members (one of the blade members 520L and 520R) and the first regions of the side surfaces 526L and 526R of the other blade member (the other of the blade members 520L and 520R) are arranged such that their positions are different in a direction orthogonal to the direction in which the game balls are guided along the side surfaces 526L and 526R.

[0226] Further, the distal end of the bulging portion 524L, which is farther from the through hole 521L, is formed to be inclined toward the through hole 521L from the front side (lower side in FIG. 24(b)) to the back side (upper side in FIG. 24(b)). On the other hand, the distal end of the bulging portion 524R, which is farther from the through hole 521R, is formed to be inclined toward the through hole 521R from the back side to the front side.

[0227] Next, with reference to FIGS. 25 and 26, a description will be given of the case where game balls are fed to the side surfaces 526L and 526R of the left and right blade members 520L and 520R. FIGS. 25(a) and 25(b) are cross-sectional views of the winning port unit 500. FIGS. 26(a) and 26(b) are cross-sectional views of the winning port unit 500.

[0228] Note that FIGS. 25(a), 25(b), 26(a), and 26(b) correspond to the cross-sectional views of the winning port unit 500 in FIG. 24(b). Also, in FIGS. 25(a) and 25(b), the transition states of the game balls when the game balls are fed from both sides of the first electric accessory 520 are illustrated in order. In FIGS. 26(a) and 26(b), the transition states of the game balls when the game balls are fed only to the left blade member 520L are illustrated in order.

[0229] As shown in FIGS. 25(a) and 25(b), when game balls are fed to both sides of the first electric accessory 520, the game balls rolling on the side surfaces 526L and 526R of the left and right blade members 520L and 520R can be rolled to different positions in the front-rear direction by the bulging portions 524L and 524R.

[0230] Specifically, as described above, the bulging portion 524L of the left blade member 520L is formed by connecting to the front end face. Therefore, the game ball that rolls on the side surface 526L of the left blade member 520L rolls on the side surface 526L while contacting the bulging portion 524L, and thus rolls to the back side.

[0231] In this case, the bulging portion 524L is formed such that the end portion on the far side from the through hole 521L inclines toward the through hole 521L side from the front side (lower side in FIG. 25(b)) to the back side (upper side in FIG. 25(b)). Therefore, when the game ball rolling on the side surface 526L contacts the bulging portion 524L, it is possible to suppress the resistance in the rolling direction from increasing and the rolling of the game ball from stopping.

[0232] On the other hand, the bulging portion 524R of the right blade member 520R is formed by connecting to the back end face. Therefore, the game ball that rolls on the side surface 526R of the right blade member 520R rolls on the side surface 526R while contacting the bulging portion 524R, and thus rolls to the front side.

[0233] In this case, the bulging portion 524R is formed such that the end portion on the far side from the through hole 521R inclines toward the through hole 521R side from the back side (upper side in FIG. 25(b)) to the front side (lower side in FIG. 25(b)). Therefore, when the game ball rolling on the side surface 526R contacts the bulging portion 524R, it is possible to suppress the resistance in the rolling direction from increasing and the rolling of the game ball from stopping.

[0234] Therefore, the game ball rolling on the left blade member 520L side can be moved toward the back side, while the game ball rolling on the right blade member 520R side can be moved toward the front side. As a result, when game balls are fed from both the left and right sides, it is possible to suppress the game balls fed from the left and right from colliding head-on.

[0235] Here, conventionally, there is known a gaming machine including a ball entry port (second winning port 140) formed so that a game ball can enter, and a guide member (first electric accessory 520) having a guide surface (side surfaces 526L and 526R) for guiding the game ball to the ball entry port and formed to be displaceable. As the guide member, for example, a pair of wing members (wing members 520L and 520R) having a guide surface for guiding the game ball to the ball entry port and disposed with the ball entry port therebetween and having a proximal end rotatably supported is exemplified.

[0236] Also, a technique is disclosed in which a first groove is provided on the entire surface of the guide surface (side surfaces 526L and 526R) of one of the wing members (either one of the wing members 520L and 520R), and a second groove is provided on the entire surface of the guide surface (side surfaces 526L and 526R) of the other wing member, respectively. According to such a technique, since the first groove and the second groove are inclined in different directions from each other, even when the game balls are simultaneously guided (rolled) on the guide surface (side surfaces 526L and 526R) of one of the wing members (either one of the wing members 520L and 520R) and the guide surface (side surfaces 526L and 526R) of the other wing member (either the other of the wing members 520L and 520R), these game balls can be biased in different directions (one is toward the glass plate side and the other is toward the game board side). Therefore, these game balls can be smoothly entered into the second winning port 140.

[0237] However, the above-described conventional technique has a problem that the game balls cannot be sufficiently biased. In addition, a game ball entering from one side of the guide member (either one of the wing members 520L and 520R) may pass through the guide surface (side surfaces 526L and 526R) and pass through the other side of the guide member (either the other of the wing members 520L and 520R). In this case, since the game ball does not enter the ball entry port (second winning port 140), there is a problem that the interest of the player is impaired.

[0238] On the other hand, according to the present embodiment, the first electric device 520 includes a pair of bulging portions 524L and 524R that project from the side surfaces 526L and 526R and are formed to be able to contact a game ball that rolls on the side surfaces 526L and 526R. Since the pair of bulging portions 524L and 524R are arranged with different positions in a direction orthogonal to the direction in which the game ball is guided along the side surfaces 526L and 526R, by bringing the game ball guided (rolling) on the side surfaces 526L and 526R into contact with the bulging portions 524L and 524R, such a game ball can be surely deflected. As a result, the game ball can be smoothly introduced into the ball entrance.

[0239] Further, since the pair of bulging portions 524L and 524R are arranged with different positions in a direction orthogonal to the direction in which the game ball is guided along the side surfaces 526L and 526R, the game ball entering from one side of the pair of wing members 520L and 520R can be brought into contact with the bulging portions 524L and 524R. Therefore, it is possible to suppress the game ball entering from one side (either one of the wing members 520L and 520R) of the pair of wing members 520L and 520R from passing through the pair of wing members 520L and 520R (to the other of the wing members 520L and 520R). As a result, the game ball can be introduced into the ball entrance, and the player's interest can be improved.

[0240] Furthermore, the first electric device 520 is formed as a pair of wing members 520L and 520R that are arranged with the second winning port 140 therebetween and whose proximal ends are rotatably supported. The pair of bulging portions 524L and 524R project from the respective side surfaces 526L and 526R of the pair of wing members 520L and 520R, and the bulging portions 524L and 524R in one of the pair of wing members 520L and 520R and the bulging portions 524L and 524R in the other of the pair of wing members 520L and 520R are arranged with different positions in a direction orthogonal to the direction in which the game ball is guided along the side surfaces 526L and 526R. Therefore, by bringing the game ball guided (rolling) on the side surfaces 526L and 526R into contact with the bulging portions 524L and 524R, such a game ball can be surely deflected. As a result, the game ball can be smoothly introduced into the second winning port 140, and ball jamming can be suppressed.

[0241] Further, the bulging portions 524L and 524R on one wing member 520L, 520R and the bulging portions 524L and 524R on the other wing member 520L, 520R are arranged with different positions in a direction orthogonal to the direction in which the game ball is guided along the side surfaces 526L and 526R (the direction from the tip side to the base end side of the wing members 520L and 520R). Thus, when the game ball that has entered the side surfaces 526L and 526R of one wing member 520L, 520R reaches the side surfaces 5.26L and 526R of the other wing member 520L, 520R, such a game ball can be made to abut against the bulging portions 524L and 524R on the other wing member 520L, 520R. Therefore, it is possible to suppress the game ball that has entered the side surfaces 526L and 526R of one wing member 520L, 520R from passing through the side surfaces 526L and 526R of the other wing member. As a result, the game ball can be made to enter the second winning opening 140, and the player's interest can be enhanced.

[0242] In other words, since the bulging portions 524L and 524R are formed at different positions in the front-rear direction on the left and right wing members 520L and 520R respectively, the game balls rolling from the left and right can be made to roll to different positions in the front-rear direction. Therefore, when the game balls are fed from both the left and right sides, it is possible to suppress the game balls fed from the left and right from colliding head-on. As a result, it is possible to suppress the time taken for the game ball to enter the second winning opening 140 from becoming long.

[0243] That is, by making the positions where the game balls collide different in the front-rear direction on the left and right, as shown in FIG. 25(b), the left game ball that has been brought closer to the back side is more likely to bounce back to the back side (upper side in FIG. 25(b)) due to the collision. On the other hand, the right game ball that has been brought closer to the front side is more likely to bounce back to the front side (lower side in FIG. 25(b)) due to the collision.

[0244] Therefore, it is possible to easily guide one game ball (which rolls the left wing member 520L in this embodiment) into the second winning opening 140, and by rebounding the other game ball to the front side, it is possible to prevent the game ball from separating too far from the second winning opening 140 when they collide. Accordingly, it is possible to speed up the entry of the second game ball that later enters the second winning opening 140 into the second winning opening 140. As a result, when game balls are fed to both the left and right sides of the first electric accessory 520, the time it takes for the game balls on both sides to enter the second winning opening 140 can be shortened, and the progress of the game can be advanced smoothly.

[0245] Further, since the bulging portions 524L and 524R project from the side surfaces 526L and 526R at a position closer to the base end side (the through hole 521 side) than the tip end side of the wing members 520L and 520R, it is possible to secure a rolling area until the game ball guided by the side surfaces 526L and 526R comes into contact with the bulging portions 524L and 524R. Therefore, it is possible to suppress a decrease in the rolling speed of the game ball by that much and smoothly guide it into the second winning opening 140.

[0246] Furthermore, since the bulging portions 524L and 524R project from the side surfaces 526L and 526R at a position closer to the base end side than the tip end side of the wing members 520L and 520R, it is possible to prevent the path of the game ball that abuts against and is deflected by the bulging portions 524L and 524R from returning to the path before deflection until it reaches in front of the entry port (the end of the guide surface). That is, it is possible to easily feed the game ball from the side surfaces 526L and 526R to the entry port while remaining in the deflected state.

[0247] Also, as described above, a first region that is continuous from the tip end side to the base end side of the wing members 520L and 520R is formed on the side surfaces 526L and 526R, and the bulging portions 524L and 524R are formed to have a size that does not contact the game ball guided by the first region. Therefore, when the game ball that has entered the side surfaces 526L and 526R rolls in the first region, it is possible to avoid a decrease in the rolling speed of the game ball and smoothly guide it into the second winning opening 140.

[0248] In this case, since the first regions of the side surfaces 526L and 526R in one of the pair of blade members 520L and 520R (either one of the blade members 520L and 520R) and the first regions of the side surfaces 526L and 526R in the other blade member (either the other of the blade members 520L and 520R) are arranged with different positions in a direction orthogonal to the direction in which the game balls are guided along the side surfaces 526L and 526R, even when the game balls are simultaneously guided (rolled) on the first regions of the side surfaces 526L and 526R in one of the blade members (either one of the blade members 520L and 520R) and the first regions of the side surfaces 526L and 526R in the other blade member (either the other of the blade members 520L and 520R), these game balls can be biased in different directions from each other, and can be smoothly introduced into the second winning port 140.

[0249] Next, as shown in FIGS. 26(a) and 26(b), when a game ball is fed to either one of the left and right blade members 520L and 520R, by bringing the game ball into contact with the bulging portion 524L or the bulging portion 524R of the other left and right blade members 520L and 520R, it is possible to suppress the game ball from rolling on the side surfaces 526L and 526R of the other left and right blade members 520L and 520R and falling from its tip.

[0250] More specifically, as described above, the bulging portion 524L of the left blade member 520L is formed by connecting to the front end surface on the front side. Therefore, the game ball rolling on the side surface 526L of the left blade member 520L rolls on the side surface 526L while contacting the bulging portion 524L, and is thus rolled to the back side. Thereby, the game ball rolling on the side surface 526L of the left blade member 520L can be moved closer to the side of the bulging portion 524R formed on the right blade member 520R.

[0251] In other words, since the bulging portions 524L and 524R formed on the left and right blade members 520L and 520R are formed at different positions in the front-rear direction, a game ball rolling one of the left blade member 520L or the right blade member 520R toward the second winning port side can be rolled (moved closer) to a position that coincides with the bulging portions 524L and 524R formed on the other of the left blade member 520L or the right blade member 520R in the front-rear direction.

[0252] Therefore, when the game ball rolls on the side surface 526L of the left blade member 520L, the game ball can be rolled (moved closer) to the back side and positioned substantially in line with the bulging portion 524R of the right blade member 520R in the front-rear direction. On the other hand, when the game ball rolls on the side surface 526R of the right blade member 520R, the game ball can be rolled (moved closer) to the front side and positioned substantially in line with the bulging portion 524L of the left blade member 520L in the front-rear direction.

[0253] As a result, when the rolling speed of the game ball rolling on either the side surface 526L or 526R is high, it is possible to prevent the game ball from riding up on the side surfaces 526L, 526R of the other left blade member 520L or right blade member 520R.

[0254] Here, in the conventional winning port unit 500, since the side surfaces 526L, 526R of the first electric accessory 520 are formed as smooth surfaces, there is a problem that a game ball fed from one side of the first electric accessory 520 rides up on the other blade members 520L, 520R and is fed to the flow-down area from the tips of the other blade members 520L, 520R.

[0255] In contrast, in the present embodiment, since the bulging portions 524L, 524R are formed at different positions in the front-rear direction on the first electric accessory 520, the game ball rolling from one blade member can be rolled to a position substantially in line with the bulging portions 524L, 524R formed on the other blade member in the front-rear direction. Therefore, by causing the game ball rolling on one of the blade members 520L, 520R to collide with the bulging portions 524L, 524R of the other blade member 520L, 520R, it is possible to prevent the game ball from riding up on the side surfaces 526L, 526R of the other blade member 520L, 520R and being fed to the game area from the tips of the blade members 520L, 520R.

[0256] Next, referring to FIGS. 27 and 28, the recessed portion 525L and the engaging portion 511b2 will be described. FIG. 27(a) is a top view of the winning opening unit 500, and FIG. 27(b) is a cross-sectional view of the winning opening unit 500 taken along line XXVIIb-XXVIIb in FIG. 27(a). FIGS. 28(a) and 28(b) are partial enlarged cross-sectional views of the winning opening unit 500 in the range XXVIII in FIG. 27(b). Note that in FIG. 28(a), the first electric accessory 520 is in the first state, and in FIG. 28(b), the state where the first electric accessory 520 is in the second state is shown respectively.

[0257] As shown in FIGS. 27 and 28, the engaging portions 511b2 formed on the second protruding portions 511b of the front base 511 are respectively disposed inside the recessed portions 525L and 525R of the left and right wing members 520L and 520R.

[0258] Also, in the first state, the engaging portion 511b2 is in contact with the end portions on the bulging portions 524L and 524R (side surfaces 526L and 526R) side of the recessed portions 525L and 525R (see FIG. 28(a)), and in the second state, the engaging portion 511b2 is in contact with the end portions on the side opposite to the bulging portions 524L and 524R (side surfaces 526L and 526R) side of the recessed portions 525L and 525R.

[0259] That is, when the first electric accessory 520 is displaced from the first state to the second state or from the second state to the first state, the displacement amount can be regulated by the engaging portion 511b2 coming into contact with the end portions of the recessed portions 525L and 525R.

[0260] Furthermore, in the first state, the rotational force acting around the axes of the through holes 521L and 521R causes the corners of the wing members 520L and 520R far from the through holes 521L and 521R to rotate in the direction toward the second winning opening 140 due to their own weights. Therefore, by the engaging portion 511b2 coming into contact with the end portions on the bulging portions 524L and 524R (side surfaces 526L and 526R) side of the recessed portions 525L and 525R, it is possible to suppress the rotation of the wing members 520L and 520R due to their own weights and hold the wing members 520L and 520R in the first state.

[0261] Also, in the first state, since the engaging portion 511b2 abuts against the end portions of the bulging portions 524L and 524R (side surfaces 526L and 526R) of the recessed portions 525L and 525R, the side surfaces of the bulging portions 524L and 524R of the blade members 520L and 520R can abut against the engaging portion 511b2. Therefore, since the rigidity of the abutting portion can be increased by the formation of the bulging portions 524L and 524R, it is possible to suppress the blade members 520L and 520R from being damaged by abutting against the engaging portion 511b2.

[0262] That is, in the present embodiment, a base member 510 that pivotally supports the blade members 520L and 520R rotatably is provided. The base member 510 includes an engaging portion 511b2 that restricts the rotation of the blade members 520L and 520R by abutting against them. Since the bulging portions 524L and 524R of the blade members 520L and 520R abut against the engaging portion 511b2 of the base member 510, damage to the blade members 520L and 520R can be suppressed. That is, since the bulging portions 524L and 524R are portions protruding from the blade members 520L and 520R (side surfaces 526L and 526R), a portion where the blade members 520L and 520R are made relatively rigid can be used as a stopper that abuts against the engaging portion 511b2 of the base member 510. Therefore, damage to the blade members 520L and 520R can be suppressed accordingly.

[0263] Furthermore, the bulging portions 524L and 524R are formed such that their side surfaces are substantially flush with the side surfaces of the proximal ends of the wing members 520L and 520R. In the closed state, since the side surfaces of the bulging portions 524L and 524R formed substantially flush with the side surfaces of the proximal ends of the wing members 520L and 520R are at least in contact with the engaging portion 511b2 of the base member 510, the reaction force input from the engaging portion 511b2 to the wing members 520L and 520R can be reduced by the amount that the portion far from the rotation axis (the side surfaces of the bulging portions 524L and 524R) can be brought into contact with the engaging portion 511b2 of the base member 510. Therefore, breakage of the wing members 520L and 520R can be suppressed. Also, for example, compared to the case where the protruding tip surfaces of the bulging portions 524L and 524R are brought into contact with the engaging portion 511b2 of the base member 510, the engaging portion 511b2 of the base member 510 can be separated from the second winning port 140, and a space serving as a flow path to the second winning port 140 can be secured. Note that, in addition to the side surfaces of the bulging portions 524L and 524R, the side surfaces of the proximal ends of the wing members 520L and 520R may also be brought into contact with the engaging portion 511b2 of the base member 510. In this case, the surface pressure can be reduced, and breakage of the wing members 520L and 520R can be further suppressed.

[0264] When the wing members 520L and 520R are closed, the bulging portions 524L and 524R are disposed below (below in FIG. 28(a)) the standing portion 511b1 formed on the front base 511. In other words, the standing portion 511b1 is disposed between the opposing bulging portions 524L and 524R.

[0265] Here, the pair of wing members 520L and 520R are arranged at a position where the opposing interval between the side surfaces 526L and 526R in the closed state is larger than the diameter of the game ball so as not to pinch the game ball. In this case, when the bulging portions 524L and 524R protrude from the side surfaces 526L and 526R, it is necessary to further separate the pair of wing members 520L and 520R by the height of the protrusion of the bulging portions 524L and 524R so as not to pinch the game ball between the bulging portions 524L and 524R, and the space required for arranging the pair of wing members 520L and 520R increases.

[0266] On the other hand, in the present embodiment, a standing portion 511b1 is provided between the opposing bulging portions 524L and 524R in the closed state. In the view in the rotation axis direction, the opposing intervals of the side surfaces 526L and 526R in the region where the bulging portions 524L and 524R are not formed are made larger than the diameter of the game ball, and the opposing interval of the bulging portions 524L and 524R is made smaller than the diameter of the game ball. Therefore, the space required for arranging the pair of blade members 520L and 520R can be suppressed.

[0267] That is, even when the pair of blade members 520L and 520R start to close (start to shift to the closed state) while the game ball is being guided (rolling) along the side surfaces 526L and 526R, the standing portion 511b1 is positioned between the opposing bulging portions 524L and 524R, so that the game ball can be discharged from between the opposing bulging portions 524L and 524R, and the game ball can be prevented from being sandwiched between the bulging portions 524L and 524R. The game ball discharged from between the opposing bulging portions 524L and 524R by the standing portion 511b1 is positioned between the opposing side surfaces 526L and 526R in the region where the bulging portions 524L and 524R are not formed. The opposing interval at such a position is made larger than the diameter of the game ball, so that the game ball is not sandwiched (see Fig. 27(a)). As a result, the opposing interval of the bulging portions 524L and 524R can be made smaller than the diameter of the game ball. Thereby, the space required for arranging the pair of blade members 520L and 520R can be suppressed. In other words, the pair of blade members 520L and 520R can be arranged in a space equivalent to the space required for arranging a conventional product in which the bulging portions 524L and 524R do not project from the side surfaces 526L and 526R.

[0268] On the other hand, in the second state, the rotational force acting around the axis of the through holes 521L521R causes the corners of the blade members 520L and 520R far from the through holes 521L and 521R to rotate downward in the gravitational direction due to their own weights. Therefore, by bringing the engaging portion 511b2 into contact with the end portions of the recessed portions 525L and 525R on the side opposite to the bulging portions 524L and 524R (side surfaces 526L and 526R), the rotation of the blade members 520L and 520R due to their own weights can be suppressed, and the blade members 520L and 520R can be held in the second state.

[0269] Therefore, since the displacement of the blade members 520L and 520R can be restricted at locations other than the drive unit 533d and the protrusions 523L and 523R described above, it is possible to suppress damage to the drive unit 533d and the protrusions 523L and 523R. Therefore, since it is not necessary to form the components large in order to increase the rigidity of the rotating member 533, the rotating member 533 can be miniaturized. As a result, the drive unit 530 can be miniaturized.

[0270] Also, in the open state, since the upper surface of the standing portion 511b1 is located below the lower ends of the side surfaces 526L and 526R in the direction of gravity and above the lower end of the second winning port 140 in the direction of gravity, the game balls guided by the side surfaces 526L and 526R can be fed to the upper surface of the standing portion 511b1, and by rolling the upper surface of the standing portion 511b1, the balls can be made to enter the second winning port 140 (see Fig. 28(b)).

[0271] Furthermore, as described above, a base member 511f having LEDs that irradiate light toward the blade members 520L and 520R (toward the second winning port 140) is disposed on the second protruding portion 511b. As shown in Fig. 28(a), in the first state, the recessed portions 525L and 525R are located on the lower side in the direction of gravity. Therefore, it is possible to easily make the light irradiated from the LEDs of the base member 511f enter the inside of the blade members 520L and 520R.

[0272] That is, by irradiating the recessed portions of the recessed portions 525L and 525R with the light of the LEDs, it is possible to suppress the reflection of the light of the LEDs on the outer surfaces of the blade members 520L and 520R. As a result, it is possible to easily make the light enter the inside of the blade members 520L and 520R. Therefore, the amount of light emitted from the inside of the blade members 520L and 520R toward the player side can be increased. As a result, even in a state via the front base 511 formed of a transparent material amount, the blade members 520L and 520R can be easily visually recognized by the player.

[0273] Further, when the blade members 520L and 520R are in the second state shown in FIG. 28(b), the recessed portions 525L and 525R are positioned substantially at the same position in the vertical direction of the through holes 521L and 521R. Therefore, it is easy to irradiate the game balls sent to the front side of the second winning port 140 with the LEDs of the base member 511f.

[0274] That is, by positioning the recessed portions of the recessed portions 525L and 525R substantially at the same position in the vertical direction of the through holes 521L and 521R, the gap between the opposing portions of the first electric accessory 520 can be increased. Therefore, it is easy to irradiate the game balls sent to the front side of the second winning port with the LEDs of the base member 511f. As a result, even in the state through the front base 511 formed of a transparent material, the player can easily visually recognize the game balls entering the second winning port 140.

[0275] Next, with reference to FIG. 29, the arrangement mode of the winning port unit 500 on the game board 13 will be described. FIG. 29 is a partially enlarged view of the game board 13 in the range XXIX of FIG. 2.

[0276] As shown in FIG. 29, the winning port unit 500 is arranged at a predetermined gap from the inner edge of the inner rail 76.

[0277] Inside the lower end portion of the inner rail 76, a first out port 71 for collecting game balls flowing down in the conventional game area is formed. Therefore, the lower end portion of the inner rail 76 is formed with a curved portion 76a that is curved with a curvature larger than the curvature of the entire inner rail 76 in order to facilitate the collection of game balls.

[0278] Therefore, the gap between the winning port unit 500 and the inner rail 76 is increased at the lower end portion of the inner reel (the portion where the curved portion 76a is formed). As described above, the fastening between the front base 511 and the rear base 512 of the winning port unit 500 is performed by obliquely inserting a driver or the like into the recessed portion 511b3 from below the front base 511.

[0279] The through-hole 511b4 is formed in the second protruding portion 511b formed at approximately the center position in the left-right direction of the front base 511. Therefore, the through-hole 511b4 can be positioned above the curved portion 76a (above in FIG. 29). Accordingly, when obliquely inserting a driver or the like into the recessed portion 511b3 from below the front base 511, the gap with the winning port unit 500 formed by the curved portion 76a can be utilized, so that it is easy to attach and detach the front base 511 from the back base 512 from the front side of the game board 13.

[0280] Also, since the inside of the recessed portion 511b3 can be made difficult for the player to visually recognize by the inner rail 76, it is possible to suppress a decrease in the player's interest by the player visually recognizing a screw or the like for fastening the front base 511 and the back base 512.

[0281] Next, referring to FIGS. 30 to 36, the decorative symbol display device 800 will be described.

[0282] First, referring to FIGS. 30 to 33, the configuration of the decorative symbol display device 800 will be described. FIG. 30(a) is a front view of the decorative symbol display device 800, and FIG. 30(b) is a cross-sectional view of the decorative symbol display device 800 taken along line XXXb-XXXb of FIG. 30(a). FIG. 31 is an exploded perspective front view of the decorative symbol display device 800, and FIG. 32 is an exploded perspective rear view of the decorative symbol display device 800. FIG. 33(a) is a front view of the inner reel 811 unfolded, and FIG. 33(b) is a front view of the outer reel 821 unfolded.

[0283] As shown in FIGS. 30 to 33, the decorative symbol display device 800 mainly includes a rotatable inner reel unit 810, an outer reel unit 820 that houses a part of the inner reel unit 810, a housing unit 880 that houses the inner reel unit 810 and the outer reel unit 820 inside, a drive motor KM1 that is attached to the housing unit 880 and rotates the inner reel unit 810, a drive motor KM2 that is attached to the housing unit 880 and rotates the outer reel unit 820, and a backlight unit 830 disposed inside the inner reel unit 810.

[0284] The inner reel unit 810 is formed by including a substantially cylindrical inner reel 811 that penetrates left and right, a rotating member 812 disposed on one end side (the left side in FIG. 30(a)) of the opening of the inner reel 811, and an annular member 813 disposed on the other end side (the right side in FIG. 30(a)) of the opening of the inner reel 811.

[0285] The inner reel 811 is formed by winding a strip-shaped sheet made of a transparent resin along the circumferential direction. As shown in FIG. 33(a), the inner reel 811 has its longitudinal direction in the vertical direction, and decorative patterns are arranged at equal intervals. Note that the inner reels 811 of each of the three decorative pattern display devices 800 arranged in parallel have different arrangements of decorative patterns.

[0286] The rotating member 812 is mainly formed by including a hub 812a formed in a substantially disk shape, a rim 812b formed in a substantially annular shape with a larger diameter than the hub 812a, and spokes 812c connecting the outer peripheral surface of the hub 812a and the inner peripheral surface of the rim 812b.

[0287] The hub 812a and the rim 812b are formed such that their respective axes are on the same straight line and are arranged at different positions in the axial direction. Therefore, the spokes 812c are formed to be inclined in the axial direction toward the outside in the radial direction of the hub 812a.

[0288] The rim 812b is a portion on its outer peripheral surface where one end side of the inner reel 811 is attached, and is formed to have an outer diameter substantially the same as the inner diameter of the inner reel 811. In other words, the circumferential distance dimension in the outer peripheral portion of the rim 812b is set to be substantially the same as the longitudinal dimension of the unfolded inner reel 811. Therefore, the inner reel 811 can be disposed (attached) to the outer peripheral surface of the rim 812b without a gap.

[0289] The hub 812a is disposed inside the inner reel 811. That is, the spoke 812c that connects the hub 812a and the rim 812b is formed to be inclined toward the other end (the annular member 813 described later) side of the opening of the inner reel 811 as it goes radially inward. Thereby, the hub 812a can be disposed inside the inner reel 811. Further, the spoke 812c is formed of a plurality of rod-shaped bodies extending from the rim 812b to the hub 812a, and has an inner opening 812c1 that opens between the spokes 812c adjacent in the circumferential direction.

[0290] The hub 812a is positioned at substantially the same position as the central position in the left-right direction of the inner reel 811 in the axial direction. Thereby, a space can be secured on the side of the annular member 813 rather than the hub 812a. A drive motor KM1 that applies a driving force for rotation to the inner reel unit 810 is connected to the hub 812a.

[0291] The drive motor KM1 has a thickness dimension in the axial direction of the inner reel 811 that is approximately half of the axial dimension of the inner reel 811. As described above, the hub 812a is positioned at substantially the same position as the central position in the left-right direction of the inner reel 811, and a space is formed in the inner portion on the other end (annular member 813) side of the opening of the inner reel 811. Therefore, most of the drive motor KM1 can be disposed inside the inner reel 811. As a result, the dimensions of the inner reel unit 810 and the drive motor KM1 in the left-right direction (the axial direction of the inner reel 811) can be reduced.

[0292] Further, the drive motor KM1 has a rotation axis disposed coaxially with the axis of the hub 812a. That is, the axis of the hub 812a is connected to the rotation axis of the drive motor KM1. As described above, since the axis of the hub 812a and the axis of the rim 812b are arranged on the same straight line, the inner reel 811 can be rotated about the axis of the inner reel 811 by the rotation of the drive motor KM1. Thereby, the pattern decorated on the inner reel 811 can be visually recognized by the player in a manner of being displaced in the vertical direction.

[0293] The annular member 813 is formed in an annular shape with an outer diameter substantially the same as the outer diameter of the rim 812b. The annular member 813 has the inner peripheral surface on the other end side (the right side in FIG. 30(a)) of the opening of the inner reel 811 attached to its outer peripheral surface.

[0294] Here, since the inner reel 811 is formed from a transparent resin sheet as described above, it has relatively low rigidity. Therefore, when the inner reel unit 810 is rotationally displaced, it may be deformed by the centrifugal force or wind pressure during rotation, etc., and there was a risk that the player could not accurately recognize the pattern decorated around it.

[0295] On the other hand, in the present embodiment, since the rim 812b of the rotating member 812 is connected to one end side of the inner reel 811 and the annular member 813 is connected to the other end side, when the inner reel unit 810 rotates, it is less likely to be displaced by the centrifugal force or wind pressure. As a result, when the inner reel unit 810 is rotationally displaced, the player can accurately recognize the pattern decorated around the inner reel 811.

[0296] Also, since the inner reel 811 can be formed from a sheet, the load on the inner reel 811 can be reduced accordingly. Therefore, the load on the drive motor KM1 when rotationally driving the inner reel unit 810 can be reduced. As a result, the rotational start of the inner reel unit 810 can be made smooth.

[0297] The outer reel unit 820 is mainly formed of an outer reel 821 formed in a cylindrical shape, a hub 823 formed in a disk shape with a smaller diameter than the outer reel 821, and spokes 822 connecting the inner peripheral surface on one end side (the left side in FIG. 30(a)) of the opening of the outer reel 821 and the outer peripheral surface of the outer reel 821.

[0298] The outer reel 821 is formed with an inner diameter larger than the outer shape of the inner reel 811 and a width dimension in the axial direction larger than the axial dimension of the inner reel 811. Further, the inner reel 811 is formed from a transparent resin material and has a predetermined thickness in the radial direction. Note that the outer peripheral surface of the inner reel 811 is decorated with a pattern, and the description of the decoration mode will be described later.

[0299] The hub 823 has its axis arranged coaxially with the outer reel 821 and is arranged at a substantially central position in the axial direction of the outer reel 821. Further, a drive motor KM2 for applying a driving force of rotation to the outer reel unit 820 is connected to the hub 823.

[0300] The spoke 822 is formed to incline in the axial direction of the outer reel 821 toward the outside in the radial direction of the hub 823, whereby a space can be formed between the spoke 822 and one end side (left side in FIG. 30(a)) of the opening of the outer reel 821. Further, the spoke 822 is formed from a plurality of rod-shaped bodies extending from the hub 823 to the edge portion 824 and includes an opening portion 822a that opens between the adjacent spokes 822 in the circumferential direction.

[0301] The thickness dimension of the drive motor KM2 in the axial direction of the outer reel 821 is set to be approximately half of the axial dimension of the outer reel 821. As described above, the position of the hub 823 in the axial direction is substantially the same as the center in the left-right direction of the outer reel 821, and a space is formed on one end (left in the left-right direction in FIG. 30(a)) side of the opening of the outer reel 821, so that most of the drive motor KM2 can be disposed inside the outer reel 821. As a result, the dimensions of the outer reel unit 820 and the drive motor KM2 in the left-right direction (axial direction of the outer reel 821) can be reduced.

[0302] The housing unit 880 is formed in a box-shaped body with an opening on the front side, and the inner reel unit 810 and the outer reel unit 820 can be housed therein. The housing unit 880 is mainly formed of a pair of left and right side wall portions 881, and an upper wall portion 882, a lower wall portion 883, and a rear wall portion 884 disposed at the edges between the pair of side wall portions 881.

[0303] The side wall portion 881 is formed from a plate-like body that is substantially rectangular in side view, and is formed to be larger than the outer diameter of the outer drum in the vertical direction (the vertical direction in FIG. 30(a)) and smaller than the outer diameter of the outer drum in the front-rear direction (the left-right direction in FIG. 30(b)).

[0304] A drive motor KM2 for driving the outer reel unit 820 is disposed on the right surface (inner surface) of the side wall portion 881 on the left side in front view (the left side in FIG. 30(a)) of the side wall portion 881, and a drive motor KM1 for driving the inner reel unit 810 is disposed on the left surface (inner surface) of the side wall portion 881 on the right side in front view (the right side in FIG. 30(a)) of the side wall portion 881. That is, the inner reel unit 810 and the outer reel unit 820 are rotationally displaced with respect to the side wall portion 881.

[0305] Further, the side wall portion 881 includes a bulging portion 881a that bulges in a curved shape corresponding to the outer peripheral surface of the inner reel 811 on the front side surface. Thereby, it is possible to suppress the light irradiated from the backlight unit 830 described later from escaping from the left and right outer sides of the inner reel 811.

[0306] Further, the side wall portion 881 is formed from a metal material. Thereby, the rigidity of the housing unit 880 can be increased. Also, by being formed from a metal material having higher thermal conductivity than a resin material in general, the heat generated inside the housing unit 880 can be discharged to the outside of the housing unit 880. As a result, it is possible to suppress the components from being damaged due to heat accumulating inside the housing unit 880.

[0307] The upper wall portion 882 and the lower wall portion 883 are plate members that form the upper and lower side surfaces of the housing unit 880, and are disposed along the upper edge portion (the upper portion in FIG. 30(b)) and the lower edge portion (the lower portion in FIG. 30(b)) of the side wall portion 881, respectively.

[0308] The width dimensions of the upper wall portion 882 and the lower wall portion in the left - right direction (the left - right direction in FIG. 30(a)) are formed to be smaller than the width dimension of the outer reel 821 in the left - right direction (axial direction). Thereby, the distance dimension between the opposing side wall portions 881 can be ensured, and the inner reel unit 810 and the outer reel unit 820 can be arranged between the opposing side wall portions.

[0309] Further, a plurality of through - holes penetrating in the radial direction with respect to the axis of the outer reel 821 are formed in the upper wall portion 882 and the lower wall portion 883. Thereby, the fluidity of air between the inside and the outside of the housing unit 880 can be enhanced. As a result, it is possible to suppress heat from accumulating inside the housing unit 880 and suppress damage to components due to the heat of the housing unit 880.

[0310] The rear wall portion 884 is a plate member that forms the side surface on the rear side of the housing unit 880, and is disposed along the edge portion on the rear side (the right side in FIG. 30(b)) of the side wall portion 881.

[0311] The rear wall portion 884 is formed with an opening 884a penetrating in the front - rear direction at a position intersecting the axis of the outer reel 821 in the horizontal direction (the left - right direction in FIG. 30(b)), and is formed with standing portions 884b that bend forward and stand upright at both left - and right - end portions where the opening 884a is formed.

[0312] The opening 884a is formed such that the width dimension in the left - right direction (the left - right direction in FIG. 30(a)) is larger than the width dimension of the outer reel 821 in the axial direction. Thereby, when the outer reel 821 moves (sways) in the front - rear direction due to the inertial force or vibration of the rotational operation, it is possible to suppress the outer reel 821 from colliding with the rear wall portion 884.

[0313] That is, when the outer reel 821 moves (sways) in the front - rear direction due to the inertial force or vibration of the rotational operation, a part of the rear side (the right side in FIG. 30(b)) of the outer reel 821 can be inserted inside the opening 884a. As a result, it is possible to suppress the outer reel 821 from colliding with the rear wall portion 884.

[0314] Also, the opening 884a allows the air fluidity between the inside and the outside of the accommodation unit 880 to be enhanced. As a result, it is possible to suppress heat from staying inside the accommodation unit 880, and to suppress components from being damaged by the heat of the accommodation unit 880.

[0315] Here, if an opening 884a larger than the width of the outer reel 821 in the axial direction is formed in the rear wall portion 884, the rigidity of the rear wall portion 884 on both the left and right sides adjacent to the opening 884a becomes low. Therefore, there was a risk that the rear wall portion 884 would bend.

[0316] Also, in this case, it is conceivable to increase the rigidity of the rear wall portion 884 on both the left and right sides adjacent to the opening 884a by increasing the opposing interval of the side wall portions 881. However, there was a problem that the unit itself of the decorative pattern display device 800 became large by increasing the opposing interval.

[0317] On the other hand, in the present embodiment, standing portions 884b are formed on both the left and right sides of the rear wall portion 884 at the position where the opening 884a is formed. Thereby, the rigidity of the rear wall portion 884 can be increased. As a result, it is possible to suppress the rear wall portion 884 from bending.

[0318] Also, in the present embodiment, the rear wall portion 884 is formed of a metal material, and the distance dimension from both left and right end portions of the opening 884a to both left and right end portions of the rear wall portion 884 is made sufficiently small. Therefore, the deformation rate of plastic deformation when forming both left and right ends of the rear wall portion 884 can be increased. As a result, the rigidity can be increased.

[0319] The backlight unit 830 is a unit that emits light from the inside of the inner reel 811 in order to make it easier for the player to recognize the pattern of the inner reel 811, and is disposed inside the front surface of the inner reel 811.

[0320] The backlight unit 830 is formed in an arc shape in a side view, and the axis of the arc is disposed coaxially with the axis of the inner reel 811. Also, the width dimension in the axial direction of the backlight unit 830 is set to be substantially the same as the width dimension in the axial direction of the inner reel 811.

[0321] In addition, the circumferential length dimension L4 of the backlight unit 830 on the inner reel 811 side is formed to be equal to the length of three patterns of the pattern decorated on the inner reel 811 described later.

[0322] Furthermore, in the backlight unit 830, three recesses 831 recessed radially inward are arranged side by side in the circumferential direction on the outer peripheral surface. Therefore, partition plates 832 standing upright on the radially outer side of the backlight unit 830 are formed between the respective recesses 831.

[0323] On the radially inner side surface of each recess 831, a base member 833 provided with an LED for irradiating light is disposed, and the LED can irradiate light toward the radially outer side of the backlight unit 830.

[0324] Each base member 833 can be independently supplied with power, and the inner reel 811 can be partially made to emit light. In this case, since each base member 833 is disposed in a region (recess 831) surrounded on all four sides, it is possible to suppress the light irradiated from the LED of the base member 833 from entering the region in front of the other base member 833. Therefore, it is easy to make the inner reel 811 emit light partially.

[0325] Next, with reference to FIG. 33, the patterns decorated on the inner reel 811 and the outer reel 821 will be described. FIG. 33(a) is a front view of the inner reel 811 unfolded, and FIG. 33(b) is a front view of the outer reel 821 unfolded.

[0326] As shown in FIG. 33(a), a plurality of patterns are drawn on the inner reel 811 at equal intervals in the circumferential direction (the vertical direction in FIG. 33). Note that the dimension L5 of one pattern in the circumferential direction is set to be one-third of the circumferential length dimension L4 of the backlight unit 830 (L5 × 3 = L4) as described above.

[0327] In addition, the inner reel 811 is formed of a material that can generally transmit light. In particular, the portion of the pattern (for example, the display of "7") has a higher light transmittance than the surrounding blank portion. Therefore, by irradiating light from the LED of the backlight unit 830 disposed inside the inner reel 811, the light of the LED can pass through the inner reel 811 and make the pattern portion appear to float. Accordingly, if the LED of the backlight unit 830 is in a light-emitting state, the pattern on the inner reel 811 can be visually recognized by the player even without the outer light (the light in the store or the light of other LEDs arranged on the pachinko machine 10) irradiating the inner reel 811.

[0328] In this embodiment, five types of ten patterns are continuously drawn in the circumferential direction, and the segment display device 600 described later enables the player to visually recognize up to three patterns from the player's side. As described above, each decorative pattern display device 800 is decorated with patterns in different arrays, and the player can visually recognize up to nine patterns.

[0329] In addition, the pachinko machine 10 displays 3×3 patterns by the inner reel 811, thereby setting a total of five winning effective lines, three horizontally parallel and two diagonally slanted. By stopping the inner reel 811 so that three "7" patterns are aligned on any of the effective lines, the occurrence of the jackpot state can be taught to the player.

[0330] As shown in FIG. 33(b), the outer reel 821 includes an undecorated surface 821a without decoration and a non-transmissive surface 821b with decoration that does not transmit light.

[0331] The undecorated surface 821a is made transmissive by not having any decoration. That is, by forming the outer reel 821 from a transparent material (a transparent resin material in this embodiment), the undecorated surface 821a that can transmit light is formed. Note that the undecorated surface 821a only needs to be formed to be light transmissive, and for example, it may be provided with a semi-transparent decoration that can transmit light.

[0332] The decorative symbol display device 800 can allow a player to visually recognize the symbols of the inner reel 811 arranged inside the outer reel 821 by rotating the outer reel unit 820 to face the non - decorative surface 821a toward the player side. That is, the player can visually recognize the symbols of the inner reel 811 through the non - decorative surface 821a of the outer reel 821.

[0333] The non - transmissive surface 821b is made non - transmissive to light by applying a black decoration to the outer peripheral surface of the outer reel 821 (the front side of the paper surface in FIG. 33(b)). Also, the length of the non - transmissive surface 821b in its circumferential direction (the vertical length in FIG. 33(b)) is formed to be equal to or more than the length corresponding to three symbols decorated on the inner reel 811.

[0334] As described above, in this embodiment, three symbols of the inner reel 811 can be displayed on the player side. Therefore, by making the length of the non - transmissive surface 821b in the circumferential direction equal to or more than the length corresponding to three symbols decorated on the inner reel 811, and by rotating the outer reel unit 820 to place the non - transmissive surface of the outer reel 821 on the player side, the inner reel 811 can be made invisible from the player side.

[0335] Note that the length of the non - transmissive surface 821b in the circumferential direction is not limited to being equal to or more than the length corresponding to three symbols decorated on the inner reel 811. It is sufficient that a circumferential length is formed such that the decoration of the inner reel 811 cannot be visually recognized from the player side. That is, it is sufficient that the non - transmissive surface 821b is formed for the circumferential length of the inner reel 811 that can be visually recognized from the player side.

[0336] Also, the non - transmissive surface 821b includes a transmissive region 821b1 that can partially transmit light and a symbol 821b2 decorated with a symbol.

[0337] The transmissive area 821b1 is formed in a rectangular shape that is long in the left-right direction (the left-right direction in FIG. 33) when viewed from the front. The transmissive area 821b1 is a part that displays 7-segment display in combination with the segment display device 600 described later, and can partially transmit the light passing through the inner reel 811 to the player side. Thereby, a part of the 7-segment display described later can be formed.

[0338] The symbol 821b2 is formed with a circumferential length corresponding to three of the symbols decorated on the inner reel 811. By stopping the outer reel 821 so that three of the symbols 821b2 of each decoration symbol display device 800 are aligned horizontally, the occurrence of the jackpot state can be taught to the player.

[0339] Also, as described above, since the periphery of the symbol 821b2 is non-transmissive, the inner reel 811 cannot be visually recognized by the player. Therefore, while performing an effect where three of the symbols of the symbol 821b2 are aligned, the symbol of the inner reel 811 can be stopped on the effective line. Accordingly, by the rotation effect of the outer reel 821, after making the player focus on the outer reel 821, the player can be made to focus on the inner reel 811 almost simultaneously when the effect of the outer reel 821 ends. As a result, it is possible to suppress the player's interest from being impaired.

[0340] Next, with reference to FIGS. 34 to 36, the inner reel unit 810 and the outer reel unit 820 will be described. FIG. 34 is a cross-sectional view of the decoration symbol display device 800 taken along line XXXIV-XXXIV in FIG. 30(a). FIG. 35 is a partially enlarged view of the decoration symbol display device 800 in the range XXXV of FIG. 34. FIG. 36(a) is a partially enlarged view of the rotating member 812, and FIG. 36(b) is a cross-sectional view of the rotating member 812 taken along line XXXVIb-XXXVIb in FIG. 36(a).

[0341] As shown in FIGS. 34 to 36, a predetermined gap is formed between the inner reel 811 of the inner reel unit 810 and the outer reel 821 of the outer reel unit 820. Also, a predetermined gap is formed between the hub 812a of the inner reel unit 810 and the edge portion 824 protruding radially toward one end side (left side in FIG. 34) of the opening of the outer reel 821 of the outer reel unit 820.

[0342] On the hub 812a of the rotating member 812, a protrusion 812a1 protruding toward the edge portion 824 side of the outer reel unit 820 is formed. The protrusions 812a1 are formed at predetermined intervals in the circumferential direction of the hub 812a (in this embodiment, they are formed on the extension lines of the spokes 812c (see FIG. 36)). The protrusions 812a1 are formed in a mountain shape with both sides inclined in the circumferential direction of the hub 812a. Therefore, by rotating the inner reel unit 810, wind can be generated by the protrusions 812a1.

[0343] Here, conventionally, a gaming machine having a first reel (outer reel unit 820) formed rotatably and a second reel (inner reel unit 810) disposed substantially concentrically inside the first reel (outer reel unit 820) and formed rotatably (that is, having a double reel structure) is known. Also, a technique is known in which a rotating brush is brought into contact with the outer peripheral surface (display surface) of the reel, and the rotating member is driven in accordance with the rotation of the reel to remove and clean dust adhering to the display surface of the reel.

[0344] However, the double reel structure has a problem that cleaning is difficult. That is, in the double reel structure, since a space for disposing the above-described rotating brush cannot be secured between the outer reel (first reel (outer reel unit 820)) and the inner reel (second reel (inner reel unit 810)), the inner peripheral surface of the outer reel and the outer peripheral surface of the inner reel (second reel) cannot be cleaned.

[0345] That is, since the opposing gap between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821 is formed to be narrow, it is necessary to disassemble the decorative pattern display device 800 to remove dust (dirt) that has entered and adhered to the opposing gap, making it difficult to clean.

[0346] In contrast, in this embodiment, when the inner reel unit 810 is rotated by the protrusion 812a1, air can be pushed out to generate wind. The pushed-out air (wind) collides with the edge 824 of the opposing outer reel 821 and then flows into the opposing gap between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821.

[0347] In this case, since the space in the opposing gap between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821 is made narrower than the space on the inner peripheral side of the edge 824 and the hub 812a, air can flow from the space on the inner peripheral side of the edge 824 and the hub 812a into the opposing gap between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821. As a result, dust (dirt) that has adhered to the outer peripheral surface of the inner reel 811 or the inner peripheral surface of the outer reel 821 and dust that is about to adhere can be blown away. Consequently, it is possible to suppress dust from adhering to the outer peripheral surface of the inner reel 811 or the inner peripheral surface of the outer reel 821.

[0348] That is, in the present embodiment, the outer reel unit 820 includes an outer reel 821 formed in a cylindrical shape and an edge portion 824 that projects radially inward from one axial side of the outer reel 821. The inner reel unit 810 includes an inner reel 811 formed in a cylindrical shape and having an outer surface facing the inner surface of the outer reel 821 at a predetermined interval, and a hub 812a that projects radially inward from one axial side of the inner reel 811 and has an outer surface facing the inner surface of the edge portion 824 at a predetermined interval. Since the protrusion 812a1 stands upright from the outer surface of the hub 812a toward the inner surface of the edge portion 824, the protrusion 812a1 displaces in the circumferential direction between the inner surface of the edge portion 824 and the outer surface of the hub 812a to generate wind pressure, and by utilizing such wind pressure, the air between the inner surface of the outer reel 821 and the outer surface of the inner reel 811 can be made to flow. Thereby, dust can be removed by the flow of air, and the inner surface of the outer reel 821 and the outer surface of the second outer peripheral surface can be cleaned.

[0349] Here, when an opening is formed in at least one of the edge portion 824 or the hub 812a, or when a part in the circumferential direction is partially divided, the wind pressure generated by the protrusion 812a1 displacing in the circumferential direction between the inner surface of the edge portion 824 and the outer surface of the hub 812a escapes from the opening portion or the divided portion, so the wind pressure weakens, and accordingly, it becomes difficult to make the air between the inner surface of the outer reel 821 and the outer surface of the inner reel 811 flow.

[0350] On the other hand, in the present embodiment, since the edge portion 824 and the hub 812a are formed in an annular shape when viewed in the axial direction and have a continuous surface in the circumferential direction, the wind pressure generated by the protrusion 812a1 displacing in the circumferential direction between the inner surface of the edge portion 824 and the outer surface of the hub 812a can be increased. Therefore, it becomes easier to make the air between the inner surface of the outer reel 821 and the outer surface of the inner reel 811 flow. As a result, by utilizing the wind pressure generated by the protrusion 812a1 displacing in the circumferential direction between the inner surface of the edge portion 824 and the outer surface of the hub 812a, it is possible to easily make the air between the inner surface of the outer reel 821 and the outer surface of the inner reel 811 flow.

[0351] Also, due to the protrusion 812a1, the facing gap between the hub 812a of the inner reel unit 810 and the edge 824 of the outer reel unit 820 is partially narrowed in the circumferential direction of the inner reel 811. Therefore, the atmospheric pressure in the facing gap between the hub 812a of the inner reel unit 810 and the edge 824 of the outer reel unit 820 can be easily changed by the protrusion 812a1. Thus, it is possible to easily generate wind by utilizing the change in atmospheric pressure, and the wind can be made to flow into the facing gap between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821, and dust (dirt) attached to the outer peripheral surface of the inner reel 811 or the inner peripheral surface of the outer reel 821 and dust that is about to adhere can be blown away. As a result, it is possible to suppress dust from adhering to the outer peripheral surface of the inner reel 811 or the inner peripheral surface of the outer reel 821.

[0352] Specifically, air has the property of flowing from a high atmospheric pressure side to a low atmospheric pressure side, and by narrowing the facing gap between the protruding tip of the protrusion 812a1 and the edge 824 of the outer reel unit 820, the atmospheric pressure can be partially increased. Therefore, the atmospheric pressure in the space between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821, where the change in atmospheric pressure is unlikely to occur, is made lower than the atmospheric pressure in the facing gap between the protruding tip of the protrusion 812a1 and the edge 824 of the outer reel unit 820. As a result, air can be easily sent into the space between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821, and it is possible to suppress dust from adhering to the outer peripheral surface of the inner reel 811 or the inner peripheral surface of the outer reel 821.

[0353] Furthermore, since the atmospheric pressure in the facing gap between the protruding tip of the protrusion 812a1 and the edge 824 can be increased, it is possible to suppress the displacement (shaking) of the protrusion 812a1 toward the edge 824 side or the edge 824 toward the protrusion 812a1 side.

[0354] In addition, since the outer opening 825 and the inner opening 812c1 are formed in the spoke 822 that supports the edge portion 824 and the spoke 812c that supports the hub 812a, the air between the inner surface of the edge portion 824 and the outer surface of the hub 812a can be exhausted to the outside (or air can be inhaled from the outside between the inner surface of the edge portion 824 and the outer surface of the hub 812a) through the outer opening 825 and the inner opening 812c1. That is, the flow resistance of the air can be reduced, and accordingly, the air between the inner surface of the edge portion 824 and the outer surface of the hub 812a can be made to flow (flow out or flow in) more easily. As a result, by utilizing the wind pressure generated when the standing portion is displaced in the circumferential direction between the inner surface of the outer reel 821 and the outer surface of the inner reel 811, the air between the inner surface of the outer reel 821 and the outer surface of the inner reel 811 can be made to flow more easily.

[0355] Furthermore, since the protrusion 812a1 is erected on the hub 812a (or the edge portion 824) of the inner reel unit 810 (or the outer reel unit 820), and at least the outer opening 825 (or the inner opening 812c1) is formed in the spoke 822 (or the spoke 812c) of the outer reel unit 820 (or the inner reel unit 810), it is easy to exhibit the effect of reducing the flow resistance by inhaling (or exhausting) air through the outer opening 825. That is, when rotating one of the outer reel unit 820 and the inner reel unit 810 on which the protrusion 812a1 is erected, by stopping the other on which the outer opening 825 or the inner opening 812c1 is formed, the resistance to the flow of air (exhausting or inhaling) through the outer opening 825 or the inner opening 812c1 can be reduced.

[0356] The outer reel 821 is formed to be inclined (enlarged in diameter) slightly radially outward from the side (one end) of the edge portion 824 to which the spoke 822 is connected toward the other end. Therefore, the air flowing in from one end side can be easily sent to the other end side between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821. As a result, it is possible to suppress the stoppage of the air flow between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821, and it is possible to suppress dust from sticking to the outer peripheral surface of the inner reel 811 or the inner peripheral surface of the outer reel 821.

[0357] Furthermore, the inclination angle θ1 of the inner reel 811 of the spoke 812c from the axis in the radially outer direction is made larger than the inclination angle θ2 of the outer reel 821 of the spoke 822 from the axis in the radially outer direction (θ1 > θ2). Therefore, when the spokes 812c and 822 are rotationally displaced to a position where they overlap in the axial direction (the left - right direction in FIG. 34), for example, the position shown in FIG. 34, the dimension between them facing radially outward (the up - down direction in FIG. 34) is increased.

[0358] Therefore, by rotationally displacing one or both of the inner reel unit 810 and the outer reel unit 820, due to the difference in the distance between the opposing spokes 812c and 822, it is easy to generate wind flowing from the outer peripheral surface of the inner reel 811 toward the inner peripheral surface of the outer reel 821.

[0359] Specifically, the separation distance between the opposing spokes 812c and 822 increases toward the radially outer side of the inner reel 811 and the outer reel 821. Therefore, when the spokes 812c and 822 are rotationally displaced to a position where they overlap in the axial direction, the atmospheric pressure is higher between the opposing spokes 812c and 822 in the radially inner part of the inner reel 811 and the outer reel 821.

[0360] As described above, air has the property of flowing from a high - pressure side to a low - pressure side. Therefore, it is possible to form an air flow from the radially inner part toward the radially outer part. That is, it is possible to form an air flow from the axial side of the inner reel 811 and the outer reel 821 toward the opposing side between the hub 812a and the edge 824. Therefore, it is easy to send air into the space between the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821. As a result, it is possible to suppress dust from sticking to the outer peripheral surface of the inner reel 811 or the inner peripheral surface of the outer reel 821.

[0361] In addition, at least a part of the outer reel 821 of the outer reel unit 820 is formed to have light transmissivity, and a plurality of symbols are arranged along the circumferential direction on the inner reel 811 of the inner reel unit 810. Therefore, the player can visually recognize the change of the symbols accompanying the rotation of the inner reel unit 810 through the outer reel unit 820. In this case, a protrusion 812a1 is erected on the hub 812a of the inner reel unit 810, that is, a protrusion 812a1 is erected on the hub 812a of the inner reel unit 810 which rotates more times than the outer reel unit 820. Therefore, in the effect produced by the rotation of the outer reel unit 820 or the inner reel unit 810, the opportunity to clean the inner surface of the outer reel 821 and the outer surface of the inner reel 811 can be increased. That is, in the double reel structure, it is easy to perform cleaning.

[0362] Note that, as the timing for cleaning the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821 by rotating the inner reel unit 810, it is preferable to perform it when the player does not operate (the game ball is not launched into the game area) and the pachinko machine 10 is in a standby state. In this case, in order to generate wind, the inner reel unit 810 is rotated at a high speed, so that the player's interest can be attracted by the switching of the symbols on the inner reel 811.

[0363] Also, the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821 may be cleaned while an effect of rotationally displacing the non-transmissive surface 821b of the outer reel 821 toward the player side is being performed. In this case, since the inner reel 811 is made invisible to the player, the cleaning can be performed without the player visually recognizing the cleaning state. As a result, it is possible to suppress a decrease in the player's interest. In addition, since it can be performed during the game state, even when the game continues for a predetermined time, the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821 can be cleaned. Therefore, it is possible to suppress the accumulation of dust and other dirt on the outer peripheral surface of the inner reel 811 and the inner peripheral surface of the outer reel 821 during the game.

[0364] Next, with reference to FIGS. 37 to 63, the segment display device 600 will be described. First, with reference to FIGS. 37 and 38, the configuration of the segment display device 600 will be described. FIG. 37 is a front view of the segment display device 600, and FIG. 38 is an exploded view of the segment display device 600.

[0365] As shown in FIGS. 37 and 38, the segment display device 600 is formed by horizontally arranging in parallel a vertical displacement unit 600L disposed on the left side in a front view, a vertical displacement unit 600R disposed on the right side in a front view, and a vertical displacement unit 600C disposed between the left and right vertical displacement units 600L and 600R, and fastening and fixing a connecting member 601 from the back side.

[0366] Since the configurations of the vertical displacement units 600L, 600C, and 600R are substantially the same, hereinafter, only the vertical displacement unit 600L disposed on the left side in a front view will be described, and detailed descriptions of the vertical displacement units 600C and 600R will be omitted.

[0367] Next, with reference to FIGS. 39 to 41, the vertical displacement unit 600L will be described. FIG. 39(a) is a front view of the vertical displacement unit 600L, and FIG. 39(b) is a side view of the vertical displacement unit 600C. FIG. 40 is an exploded perspective front view of the vertical displacement unit 600L, and FIG. 41 is an exploded perspective back view of the vertical displacement unit 600L.

[0368] Note that FIGS. 40 and 41 illustrate an exploded state of the first segment unit 610, the second segment unit 620, and the displacement unit 650.

[0369] As shown in FIGS. 39 to 41, the vertical displacement unit 600L includes a displaceable displacement unit 650, and a first segment unit 610 and a second segment unit 620 disposed on the left and right of the displacement unit 650.

[0370] Note that the first segment unit 610 is a unit capable of displaying one segment in the left - right direction, and the second segment unit 620 is a unit capable of displaying two segments in the left - right direction. Also, since the first segment unit 610 is formed only by halving the second segment unit 620 in the left - right direction, hereinafter, only the second segment unit 620 will be described, and the reference numerals in the configuration of the second segment unit 620 will be similarly assigned to the first segment unit 610.

[0371] Each of the vertical displacement units 600L, 600C, and 600R is formed with different arrangements of the first segment unit 610 and the second segment unit 620. In the vertical displacement unit 610C, the second segment unit 620 is disposed only on the right side in the front view. In the vertical displacement unit 610R, the second segment unit 620 is disposed in the view on the right side in the front view.

[0372] Therefore, the vertical displacement unit 600L can display one - segment display on the left side in the front view and two - segment display on the right side in the front view, respectively. Also, the vertical displacement unit 600C can display two - segment display only on the right side in the front view. Further, the vertical displacement unit 600R can display one - segment display only on the right side in the front view. That is, it can be configured such that one - segment is formed on both the left and right sides of each of the vertical displacement units 600L, 600C, and 600R.

[0373] Next, referring to FIGS. 42 to 44, the second segment unit 620 will be described. FIG. 42(a) is a front view of the second segment unit 620, and FIG. 42(b) is a rear view of the second segment unit 620. FIG. 43 is an exploded perspective front view of the second segment unit 620, and FIG. 44 is an exploded perspective rear view of the second segment unit 620.

[0374] As shown in FIGS. 42 to 44, the second segment unit 620 is mainly formed of a light transmissive member 621 disposed on the front side, a partition member 622 disposed on the back surface of the light transmissive member 621, a plurality of diffusion members 623 disposed on the back surface of the partition member 622, a base member 624 disposed between the plurality of diffusion members 623, and reflection members 625 disposed on both sides adjacent to the base member 624.

[0375] The light transmissive member 621 is formed of a translucent resin material through which light can pass. The light transmissive member 621 is mainly formed of a light transmissive portion 621a formed in an arc-shaped plate convex on the front side and flat portions 621b formed continuously above and below the light transmissive portion 621a.

[0376] The light transmissive portion 621a is mainly formed of standing walls 621a1 erected from the left and right ends to the back side, fastening portions 621a2 protruding in an annular shape from the upper and lower ends to the back side, and a decorative portion 621a3 recessed continuously in the vertical direction at the center position on the left and right of the front side.

[0377] The standing walls 621a1 are erected from the left and right ends of the light transmissive portion 621a to the back side. The opposing dimension between the standing walls 621a1 is set to be substantially the same as the width dimension of the partition member 622 in the left-right direction described later. Therefore, when the partition member 622 is disposed on the back side of the light transmissive portion 621a, the partition member 622 can be restricted from moving left and right.

[0378] The fastening portion 621a2 is a protrusion that forms a hole for fastening the reflection member 625 described later with a screw, and is formed to protrude in an annular shape from the back side of the light transmissive portion 621a. Therefore, the reflection member 625 can be fastened by screwing the tip of the screw into the inner edge portion of the fastening portion 621a2.

[0379] The decorative portion 621a3 is recessed continuously in the vertical direction at the center position on the left and right of the light transmissive portion 621a as described above. Thereby, it is possible to suppress light transmitted from the left side in the front view from being reflected inside the decorative portion 621a3 and emitted from the right side in the front view. A detailed description of the light transmitted through the decorative portion 621a3 will be given later.

[0380] The flat portion 621b is a plate member for fastening to the base member 660 of the displacement unit 650 described later. The flat portion 621b is formed as a plate-like body having substantially the same front view shape as the base member 660, and the displacement unit 650 and the second segment unit 620 can be fastened by fastening a screw through the flat portion 621b.

[0381] Further, elastic pieces 621b1 protruding toward the opposing side are formed to protrude from the flat portion 621b. The elastic pieces 621b1 are formed to protrude from the opposing side surfaces of the pair of upper and lower flat portions 621b and protrude in a curved shape convex toward the front side. Further, the elastic pieces 621b1 are formed in a curved shape with a radius smaller than that of the light transmission portion 621a, and the protruding tips thereof are configured to contact the upper wall portion 882 or the lower wall portion 883 of the decorative pattern display device 800 disposed inside the displacement unit 650. Thereby, when the inner reel unit 810 and the outer reel unit 820 of the decorative pattern display device 800 are rotationally driven, vibration of the decorative pattern display device 800 can be suppressed.

[0382] The partition member 622 is formed of a resin material that is difficult to transmit light and is formed in a plate shape that is curved in a side view. The radius of the curved outer peripheral surface of the partition member 622 is set to be substantially the same as the radius of the inner peripheral surface of the light transmission portion 621a, and the width in the vertical direction (vertical direction in FIG. 42) is set to be smaller than the width in the vertical direction of the light transmission portion 621a. Therefore, the outer peripheral surface of the partition member 622 can be disposed in contact with the inner peripheral surface of the light transmission portion 621a.

[0383] Further, the partition member 622 is mainly formed with a first recessed portion 622a recessed from both left and right end surfaces (left and right in FIG. 42) toward the center in a front view, a second recessed portion 622b recessed from both upper and lower end surfaces (upper and lower in FIG. 42) toward the center, and a protruding portion 622c protruding from the left and right center positions on the back side.

[0384] The first recessed portion 622a is formed in two vertically arranged rows on both the left and right sides. That is, the first recessed portion 622a is formed at four locations on the partition member 622.

[0385] The second recessed portion 622b is formed by recessing from both the upper and lower ends. The dimension between the opposing sides at the recessed tip of the second recessed portion 622b is set to be substantially the same as the vertical separation distance of the fastening portion 621a2 formed on the light transmissive member 621. Therefore, when the partition member 622 is disposed on the back side of the light transmissive member 621, by inserting the fastening portion 621a2 inside the second recessed portion 622b, movement of the partition member 622 in the vertical direction can be suppressed.

[0386] The protruding portion 622c is formed to extend vertically at the left - right center position of the partition member 622. Further, the protruding portion 622c is provided with a recess 622c1 recessed in its protruding tip surface. The width dimension of the recess 622c1 in the left - right direction is formed to be larger than the thickness dimension of the base member 624 described later. Therefore, when disposing the base member 624 on the partition member 622, the tip side of the base member 624 can be inserted inside the recess 622c1. As a result, when arranging the base member 624, the base member 624 can be positioned and movement of the base member 624 in the left - right direction can be suppressed.

[0387] The diffusion member 623 is formed from a white - turbid resin material and can diffuse the light entering therein. The diffusion member 623 is formed in a plate shape that is curved in a side view, and the radius of its outer peripheral portion (front side) is set to be substantially the same as the radius of the inner peripheral portion (back side) of the partition member 622. Therefore, the diffusion member 623 can be disposed in a state of being in contact with the back side of the partition member 622.

[0388] Also, two diffusion members 623 are arranged side - by - side vertically and two are disposed with a predetermined distance apart horizontally. That is, four diffusion members 623 are disposed on the back side of the partition member 622.

[0389] The width dimension of the diffusion member 623 in the left - right direction is set to be substantially the same as the opposing dimension between the standing wall 621a1 of the light - transmissive member 621 and the protruding portion 622c of the partition member 622. Thereby, when the diffusion member 623 is disposed on the back side of the partition member 622, the diffusion member 623 can be suppressed from moving left and right.

[0390] Further, the diffusion member 623 is formed with a protruding portion 623a protruding to the front side and a recessed portion 623b recessed on the back side of the protruding portion 623a.

[0391] The protruding portion 623a is formed to protrude at a position corresponding to the first recessed portion 622a of the partition member 622 disposed on the front side of the diffusion member 623, and is disposed in a state of being inserted inside the first recessed portion 622a. Thereby, when the diffusion member 623 is disposed on the back side of the partition member 622, the partition member 622 can be suppressed from shifting in the left - right and up - down directions.

[0392] Further, the protruding distance of the protruding portion 623a is set to be smaller than the thickness dimension of the partition member 622. That is, it is disposed in a state where a predetermined gap is formed between the protruding front end surface of the protruding portion 623a and the back surface of the light - transmissive member 621 (see FIG. 45).

[0393] The recessed portion 623b is recessed on the side opposite to the protruding portion 623a (the back side of the diffusion member 623) to have a shape slightly smaller than the front - view shape of the protruding portion 623a. This can make the plate thickness of the diffusion member 623 substantially constant and suppress distortion when the diffusion member 623 is die - formed. Also, since the recessed portion 623b is formed to have a shape slightly smaller than the protruding portion 623a, the area on the back side of the end portion of the protruding portion 623a can be increased. Therefore, the light incident from the LED 624a, which will be described later, onto the diffusion member 623 can be increased at the end portion of the protruding portion 623a. As a result, the mode of the light visually recognized by the player through the diffusion member 623 can be made distinct, and the decline of the player's interest can be suppressed.

[0394] The base member 624 is formed from a crescent-shaped plate body with a curved front side and is provided with LEDs 624a that irradiate light to the side surfaces. The radius of the arc of the base member 624 is set to be substantially the same as the radius of the recessed front end surface of the recess 622c1 formed in the partition member 622. Therefore, when disposing the base member 624 on the back surface of the partition member 622, by inserting the base member 624 inside the recess 622c1 of the partition member 622, it is possible to suppress the base member 624 from being displaced in the left-right direction.

[0395] A plurality of LEDs 624a are disposed on both the left and right side surfaces of the base member 624, and their irradiation directions are perpendicular to the side surfaces of the base member 624. That is, the light irradiation direction of the LEDs 624a is in the left-right direction. A detailed description of the light irradiation of the LEDs 624a will be given later.

[0396] The reflecting members 625 are disposed one on each of the left and right sides of the base member 624. The reflecting members 625 are formed from a white resin material and are formed in a convex arc shape on the front side. Also, the radius of the arc of the reflecting member 625 is set to be substantially the same as the radius of the inner peripheral surface of the diffusing member 623. Thereby, when the reflecting member 625 is disposed on the back side of the diffusing member 623, the reflecting member 625 and the diffusing member 623 can be in a grounded state.

[0397] The reflecting member 625 is formed into a plate body that is spaced apart from the base member 624 in the left-right direction from the back side toward the front side, and mainly includes an inclined portion 625a that is inclined from the back side toward the front side, a plurality of recesses 625b that are recessed and formed side by side in the vertical direction on the front side of the inclined portion 625a, and wall portions 625c that protrude toward the front side at the upper end portion, lower end portion, and middle portion of the recesses 625b.

[0398] The front side of the inclined portion 625a is a reflecting surface 625a1 that reflects the light of the LED 624a of the base member 624 to the front side, and is formed to be inclined at approximately 60 degrees with respect to the side surface of the base member 624. As described above, since the irradiation direction of the light of the LED 624a is perpendicular to the side surface of the base member 624, the reflecting surface 625a1 is inclined with respect to the side surface of the base member 624, so that the light irradiated from the LED 624a can be reflected to the front side. Note that the mode in which the light of the LED 624a travels will be described later.

[0399] The recess 625b is formed by being recessed in a concave curved shape that protrudes toward the back side. Further, the recess 625b is formed at a position corresponding to the LED 624a of the base member 624, whereby the amount of light of the LED 624a visually recognized by the player via the diffusing member 623 can be made uniform. As a result, it is possible to suppress a decrease in the player's interest.

[0400] Next, with reference to FIG. 45, the progress of the light irradiated from the LED 624a of the second segment unit 620 will be described in detail. FIG. 45 is a cross-sectional view of the second segment unit 620 taken along line XLV-XLV of FIG. 42(a). In FIG. 45, a part of the mode of the light irradiated from the LED 624a is illustrated by a two-dot chain line. Further, the outer shape of the decorative symbol display device 800 disposed on the left and right back sides of the second segment unit 620 is illustrated by a two-dot chain line.

[0401] As shown in FIG. 45, since the reflecting surface 625a1 is formed to be inclined at an obtuse angle with respect to the side surface of the base member 624 (that is, the light irradiated from the LED 624a and the reflecting surface 625a1 intersect at an acute angle), the reflection direction of the light can be directed outward. In this case, since the reflecting member 625 is formed from a plate member having a substantially constant thickness, the space on the opposite side of the reflecting surface 625a1 (the back side of the reflecting member 625) can be increased. Thereby, the end portion of the decorative symbol display device 800 can be disposed on the back side of the second segment unit 620.

[0402] Here, there is a rotatable decoration pattern display device 800 formed by a plurality of members arranged in parallel at a predetermined interval, a decorative member (light transmissive member 621) disposed along between the plurality of rotating cylinders and having at least a part with light transmissivity, and a substrate (base member 624) disposed on the back side of the decorative member and mounted with a plurality of light emitting means (LED 624a). There is known a gaming machine in which the substrate is disposed in a posture such that the surface on which the light emitting means is mounted is substantially orthogonal to the back of the decorative member. According to this gaming machine, not only can the space between the rotating cylinders be shielded from the player by the decorative member, but also a pattern is formed (displayed) on the surface of the decorative member by the light of the light emitting means transmitted through the decorative member, and an effect can be performed to visually recognize the pattern of such a decorative member integrally with the pattern displayed on the outer peripheral surface of the rotating cylinder by the player.

[0403] However, in the above-described conventional gaming machine, since the substrate is disposed in a posture such that the surface on which the light emitting means is mounted is orthogonal to the back of the decorative member, the light emitted from the light emitting means cannot sufficiently irradiate the back of the decorative member, and the pattern formed (displayed) by the light of the light emitting means cannot be made sufficiently large. Therefore, there has been a problem that the effect of the presentation is insufficient. On the other hand, if the decorative member (the area excluding the pattern) is enlarged while the pattern formed (displayed) by the light of the light emitting means remains small, the unity between the decorative member and the rotating cylinder is impaired.

[0404] On the contrary, according to the present embodiment, since the reflective member 625 for reflecting the light emitted from the LED 624a to the back of the light transmissive member 621 is provided, even when the base member 624 is disposed in a posture such that the surface on which the LED 624a is mounted is orthogonal to the back of the light transmissive member 621, the irradiation range of the back of the light transmissive member 621 by the light emitted from the LED 624a can be widened. Therefore, accordingly, the pattern formed (displayed) by the light of the LED 624a can be enlarged, and the effect of the presentation can be enhanced. Further, since the area excluding the pattern can be reduced as much as the pattern formed (displayed) by the light of the LED 624a can be enlarged, the unity between the light transmissive member 621 and the decorative pattern display device 800 can be formed.

[0405] Further, as shown in FIG. 45, the light transmission member 621 is located on the front side of the outer peripheral surface of the decorative pattern display device 800 and has an outer edge extending to a position overlapping the outer peripheral surface of the decorative pattern display device 800 in a front view. Therefore, it is easy to shield (make it difficult to visually recognize) the axial end surface of the decorative pattern display device 800 from the player. In addition, since the pattern of the light transmission member 621 formed (displayed) by the light emitted from the LED 624a can be made closer to the pattern displayed on the outer peripheral surface of the decorative pattern display device 800, it is easy to form a sense of unity between the light transmission member 621 and the decorative pattern display device 800.

[0406] Furthermore, the reflection member 625 connects the surface of the base member 624 on which the LED 624a is mounted and the back surface of the light transmission member 621, thereby surrounding the region where the LED 624a is mounted in the base member 624 and the region where the pattern is formed in the light transmission member 621. The back surface of the reflection member 625 is inclined in a direction away from the axial end surface of the decorative pattern display device 800 as it goes from the light transmission member 621 to the base member 624. Therefore, while ensuring the size of the pattern formed (displayed) by the light emitted from the LED 624a, the back surface of the light transmission member 621 can be brought close to the outer peripheral surface of the decorative pattern display device 800, and the decorative pattern display device 800 can be made to enter the back side of the light transmission member 621 (bring the decorative pattern display device 800 close to the base member 624). As a result, it is easy to shield (make it difficult to visually recognize) the axial end surface of the decorative pattern display device 800 from the player, and it is easy to form a sense of unity between the light transmission member 621 and the decorative pattern display device 800.

[0407] In addition, since the LED 624a is mounted on both the one side surface and the other side surface of the base member 624, different patterns can be independently formed (displayed) on the light transmission member 621 by the light emitted from the LED 624a mounted on the one side surface and the light emitted from the LED 624a mounted on the other side surface, respectively.

[0408] In this case, the number of base members 624 disposed between the decorative pattern display devices 800 arranged side by side can be made one. Therefore, the space required for disposing the base member 624 can be suppressed, and accordingly, the decorative pattern display device 800 can be made to enter deeper into the back side of the light transmission member 621 (the decorative pattern display device 800 can be brought closer to the base member 624). As a result, it is easy to shield the axial end face of the decorative pattern display device 800 from the player (difficult to visually recognize), and it is easy to form a sense of unity between the light transmission member 621 and the decorative pattern display device 800.

[0409] Furthermore, as described above, since the reflecting surface 625a1 is formed to be inclined at an obtuse angle with respect to the side surface of the base member 624 (that is, the light irradiated from the LED 624a and the reflecting surface 625a1 intersect at an acute angle), the reflection direction of the light can be directed outward. As a result, the reflecting member 625 can be made smaller (than when the reflecting surface 625a1 is inclined at an acute angle with respect to the side surface of the base member 624). Therefore, the space on the back side of the second segment unit 620 can be secured accordingly. As a result, the second segment unit 620 and the decorative pattern display device 800 can be arranged closer to each other, and accordingly, it is easy to form a sense of unity between the light transmission member 621 and the decorative pattern display device 800.

[0410] Next, with reference to FIGS. 46 and 47, the relationship between the LED 624a and the concave portion 625b will be described. FIG. 46 is a side view of the base member 624. FIG. 47 is a cross-sectional view of the second segment unit 620 taken along line XLVII-XLVII in FIG. 42(a).

[0411] As shown in FIG. 46, the LED 624a is formed in a quadrangular shape in side view and is capable of irradiating light from the entire area of the square. The LEDs 624a are arranged at intervals of an inclination angle θ1 in the circumferential direction about an axis substantially the same as the bending axis on the front side of the base member 624. Thereby, the heat accumulated in the base member 624 due to the irradiation of the LED 624a can be dispersed. As a result, it is possible to suppress the base member 624 from having locally high heat and the LED 624a from being damaged.

[0412] In the present embodiment, eight LED624a are dispersedly arranged in the circumferential direction. Further, the LED624a are arranged in a direction such that one side of the light emitting surface formed in a square shape is along the tangential direction in the curved shape of the base member 624.

[0413] Here, a game machine is known that includes a substrate (base member 624) on which a plurality of light emitting means (LED624a) are mounted, and a transmissive member (light transmissive member 621) that transmits the light emitted from the light emitting means. The transmissive member (light transmissive portion 621a of the light transmissive member 621) is formed in a curved shape, and a plurality of light emitting means are arranged along the curve of the transmissive member. In this case, the plurality of light emitting means are arranged at equal intervals in the front view of the transmissive member. That is, they are at equal intervals along the direction of the line segment (chord) connecting both ends of the curved line (arc) formed by the plurality of light emitting means. However, in the above-described game machine, since the interval between adjacent light emitting means among a part of the plurality of light emitting means is narrowed, there is a problem that the distribution of heat generated by the light emitting means is biased. Therefore, heat is concentrated on some of the light emitting means, which easily leads to a reduction in lifespan.

[0414] On the other hand, according to the present embodiment, since the LED624a are arranged at substantially equal intervals in the circumferential direction, the interval between adjacent LED624a can be made constant for each LED624a, and the distribution of heat generated by the LED624a can be made uniform. As a result, it is possible to suppress heat from concentrating on some of the LED624a and improve the lifespan of each LED624a.

[0415] As shown in FIG. 47, the recesses 625b are formed one by one on the back side (the right side in FIG. 47) of each LED624a. Further, the separation distance X1 from one end side (lower end side) to the other end side (upper end side) in the vertical direction of one recess 625b is set to be the same.

[0416] Here, as described above, the LEDs 624a are arranged at equal intervals at an angle of the inclination angle θ1 in the circumferential direction. Therefore, the vertical interval between the respective LEDs 624a is made narrower at the center side in the vertical direction (the vertical direction in FIG. 46) than at the outer side in the vertical direction. Accordingly, there has been a problem that the amount of light reflected by the reflecting member 625 and irradiated toward the player side increases at the center side in the vertical direction (the center side in the vertical direction becomes darker), and the light cannot be visually recognized by the player uniformly.

[0417] In other words, when a plurality of LEDs 624a are arranged at equal intervals (that is, at equal intervals in the circumferential direction) along the curvature of the light transmission portion 621a, those plurality of LEDs 624a are arranged at unequal intervals in a front view of the light transmission portion 621a. That is, in a front view of the light transmission portion 621a, a region where the intervals between the LEDs 624a are narrow and a region where the intervals are wide are formed. Therefore, the distribution of the light amount becomes non-uniform along the arrangement direction of the plurality of LEDs 624a.

[0418] On the other hand, in the present embodiment, a reflecting member 625 that reflects the light emitted from the LED 624a toward the light transmission portion 621a is provided. The reflecting member 625 includes a plurality of recesses 625b partitioned corresponding to the plurality of LEDs 624a, and the partition widths of those plurality of recesses 625b in a front view of the light transmission portion 621a are set to be substantially the same. Therefore, the amount of light of each recess 625b visually recognized in a front view of the light transmission portion 621a can be made substantially the same. As a result, the distribution of the light amount along the arrangement direction of the plurality of LEDs 624a can be made uniform.

[0419] That is, since the separation distance X1 from one end side (lower end side) in the vertical direction to the other end side (upper end side) of one recess 625b is set to be the same respectively, the region of the light emitted to the player side by the irradiation of one LED 624a can be made substantially the same in the vertical direction. Accordingly, it is possible to suppress an increase in the amount of light irradiated to the player side at the center side in the vertical direction. As a result, the light can be visually recognized by the player uniformly.

[0420] In addition, since the light-emitting surface of the LED 624a is formed in a rectangular shape (square) when viewed from the front, for example, compared with the case where the light-emitting surface is circular, light diffusibility can be ensured (light can be emitted at a wider angle), and thus the light quantity distribution in the recess 625b can be made uniform.

[0421] Note that the light-emitting surface means the front surface of the encapsulating resin that encapsulates the LED chip. Therefore, the light-emitting surface being rectangular when viewed from the front means that the front-view shape of the encapsulating resin (the front-view shape of the internal space of the reflector surrounding the encapsulating resin) is rectangular.

[0422] Furthermore, at least a part of the plurality of LEDs 624a is arranged in a direction such that one side of the light-emitting surface is along the tangential direction of the curved shape of the light-transmitting portion 621a. Therefore, the light emitted from the LED 624a can be easily diffused uniformly along the curve of the light-transmitting portion 621a. As a result, the distribution of the light quantity visually recognized through the light-transmitting portion 621a can be made uniform.

[0423] In addition, the recess 625b faces the back surface of the light-transmitting portion 621a and is formed as a curved surface that is recessed on the side away from the back surface of the light-transmitting portion 621a. Since the light-emitting surface of the LED 624a faces the opposing space between the light-transmitting portion 621a and the recess 625b, the base member 624 can be arranged in a posture perpendicular to the light-transmitting portion 621a. That is, the degree of freedom in arranging the unit composed of the light-transmitting portion 621a, the base member 624, and the reflecting member 625 can be increased. In this case, since the recess 625b is arranged in a manner that surrounds the periphery of the light emitted from the light-emitting surface of the LED 624a from a direction perpendicular to the traveling direction of the light, the light reflected by the recess 625b can be uniformly incident on the back surface of the light-transmitting portion 621a. As a result, the distribution of the light quantity visually recognized through the light-transmitting portion 621a can be made uniform.

[0424] Next, with reference to FIG. 48, the mode of the light irradiated by the LED 624a will be described. FIG. 48 is a front view of the vertical displacement unit 600L. In FIG. 48, the light irradiated by the LED 624a is illustrated by a two-dot chain line and is also illustrated with the reference sign of the irradiation region SR1.

[0425] As shown in FIG. 48, by emitting light from the LED 624a, the first segment unit 610 is irradiated with light from two irradiation regions SR1 arranged in the vertical direction (the vertical direction in FIG. 48). Further, the second segment unit 620 is irradiated with light from the irradiation regions SR1 arranged in a 2×2 pattern in the vertical and horizontal directions. Note that the irradiation regions SR1 of the second segment unit 620 are formed on the left and right sides sandwiching the decorative portion 621a3 of the light transmission member 621.

[0426] Therefore, the left and right sides of the number in the 7-segment display can be displayed by the irradiation region SR1 of the first segment unit 610 and the left side of the irradiation region SR1 of the second segment unit 620. The upper, lower, and center of the number in the 7-segment display will be described later.

[0427] Next, with reference to FIGS. 49 and 50, the configuration of the displacement unit 650 will be described. FIG. 49 is an exploded perspective front view of the vertical displacement unit 600L, and FIG. 50 is an exploded perspective rear view of the vertical displacement unit 600L. In FIGS. 49 and 50, the state in which the displacement unit 650 of the vertical displacement unit 600L is disassembled is shown.

[0428] As shown in FIGS. 49 and 50, the displacement unit 650 mainly includes a pair of left and right base members 660 disposed, a displacement member 670 pivotally supported by the base member 660 and rotationally displaced, and a drive means 680 that transmits the rotational drive of the drive motor KM3 disposed on the base member 660 to the displacement member 670.

[0429] The base member 660 is formed of a pair of plate members on the left and right having a shape with a space larger than the above-described decorative pattern display device 800 at the center. Further, the first segment unit 610 is disposed on the front side of the base member 660 on the left side in the front view, and the second segment unit 620 is disposed on the front side of the base member 660 on the right side in the front view. Note that the base members 660 are arranged in the left and right with the up-down and left-right reversed. In the present embodiment, only the base member 660 on the left side in the front view will be described, and the description of the base member 660 on the left side in the front view will be omitted.

[0430] The base member 660 is formed in a rectangular shape that is long in the vertical direction in side view, and includes a protruding portion 661 that curves and protrudes convexly toward the front side from the side surface on the front side thereof. Further, the base member 660 includes a through hole 662 through which the shaft of a drive motor KM3 disposed at one end (upper end) in the vertical direction is inserted, an insertion hole 663 through which a connecting rod 681 disposed at both ends (lower ends) in the vertical direction is inserted, a concave portion 664 in which a displacement member 670 described later is pivotally supported, a sliding groove 665 formed in an arc shape centered on the axis of the concave portion 664, and an engaging portion 666 that protrudes upward and downward from the concave portion 664 and mainly formed.

[0431] The radius of the protruding tip of the protruding portion 661 is set to be smaller than the radius on the inner peripheral surface of the above-described reflecting member 625, and the bending axis thereof is set to be substantially on the same straight line as the bending axis of the reflecting member 625. Therefore, when the first segment unit 610 and the second segment unit 620 are disposed on the base member 660, it is possible to suppress contact between the protruding portion 661 and the reflecting member 625, and it is possible to suppress heat of the base member 624 from entering between the opposing base members 660. As a result, the temperature of the decorative pattern display device 800 disposed inside the opposing base member 660 rises, and it is possible to suppress the drive motors KM1 and KM2 that rotationally drive the inner reel unit 810 and the outer reel unit 820 from breaking.

[0432] The through hole 662 is a hole through which the shaft of the drive motor KM3 and a gear 682 connected to the shaft are inserted. The inner diameter thereof is formed to be larger than the outer shape of the gear 682 and is set to be smaller than the main body of the drive motor KM3. Therefore, the drive motor KM3 can be disposed on the base member 660 with the gear 682 connected thereto. The drive motor KM3 is attached to the base member 660 from the side between the opposing base members 660 disposed opposite to each other.

[0433] The through hole 662 is a hole into which a connecting rod 681 of a drive means 680 described later is inserted. It is formed to be larger than the outer shape of the connecting rod 681 and is formed at both upper and lower ends of the base member 660.

[0434] The recess 664 is formed by being recessed in a circular shape from the inner side between the opposing sides of the base member 660 toward the outside. The recess 664 is formed to be slightly larger than the outer diameter of the connecting protrusion 671b of the displacement member 670 described later. Thereby, the connecting protrusion 671b can be inserted and disposed inside the recess 664.

[0435] By inserting the connecting protrusion 671b of the displacement member 670 into the sliding groove 665, the displacement member 670 can be connected to the driving means 680 disposed outside the pair of base members 660. Further, by setting the state such that the connecting protrusion 671b is inserted into the sliding groove 665, the displacement of the displacement member 670 can be guided. Therefore, the displacement of the displacement member 670 can be performed smoothly.

[0436] The engaging portion 666 is formed on the opposing side of the base member 660 with a gap at its tip that is larger than the diameter of the opposing side surface of the base member 660 and one end of the torsion spring SP1 described later. Thereby, one end of the torsion spring SP1 can be engaged with the engaging portion 666.

[0437] The displacement members 670 are arranged in a pair facing in opposite directions vertically. The displacement member 670 is formed of an extending member 671 whose one end is pivotally supported by the base member 660 and a decorative unit 672 connected to the other end side of the extending member 671.

[0438] The extending member 671 is formed in a substantially L-shaped plate shape and a pair of them are arranged facing in opposite left and right directions. The extending member 671 mainly includes a pivot support hole 671a penetrating in the left-right direction at one end on the longitudinal side, a connecting protrusion 671b protruding outward in the left and right directions at a substantially central position in the longitudinal direction on the longitudinal side, a protrusion 671d protruding in the circumferential direction of the pivot support hole 671a from the side surface on the longitudinal side, and an elastic member 671f made of an elastic material and disposed on the side surface of the extending member 671.

[0439] The shaft support hole 671a is a hole for inserting the collar C inside, and its inner diameter is formed larger than the outer diameter of the collar C. Therefore, by inserting the collar C into the shaft support hole 671a and fastening and fixing the collar C with screws inside the recess 664 of the base member 660, the displacement member 670 can be connected to the base member 660 in a rotatable state.

[0440] Also, by coaxially arranging the shaft support holes 671a of the pair of displacement members 670, inserting the collar C through the shaft support holes 671a of the pair of displacement members 670 and fastening and fixing it to the base member 660, the upper and lower displacement members 670 are arranged to be rotatable coaxially.

[0441] Furthermore, on the left and right extending members 671, a bulging portion 671a1 that bulges outward in the left - right direction is formed around one of the shaft support holes 671a. The outer diameter of the bulging portion 671a1 is formed slightly smaller than the inner diameter of the recess 664 of the base member 660. Also, the bulging portion 671a1 is arranged on the left - right outer sides of the pair of displacement members 670.

[0442] That is, in this embodiment, since the bulging portion 671a1 is formed in the shaft support hole 671a on the right side of the displacement member 670 arranged on the upper side, the shaft support hole 671a on the right side of the displacement member 670 arranged on the lower side is arranged inside the bulging portion 671a1. On the other hand, since the bulging portion 671a1 is formed in the shaft support hole 671a on the left side of the displacement member 670 arranged on the lower side, the shaft support hole 671a on the left side of the displacement member 670 arranged on the upper side is arranged inside the bulging portion 671a1 (see Fig. 49).

[0443] Thereby, when arranging the displacement member 670 on the base member 660 by the collar C, the bulging portion 671a1 can be inserted into the inside of the recess 664. As a result, when a force acts in the radial direction of the axis of the shaft support hole 671a of the displacement member 670, the outer peripheral surface of the bulging portion 671a1 and the inner peripheral surface of the recess 664 come into contact, suppressing the breakage of the shaft support hole 671a or the collar C.

[0444] That is, in the present embodiment, since the pair of displacement members 670 arranged coaxially on the base member 660, the axial length of the color C is increased accordingly. Therefore, when a force acts in the radial direction with respect to the rotation axis of the displacement member 670, the force easily acts greatly on the rotation axis. For this reason, where the shaft support hole 671a or the color C is likely to be damaged, when the bulging portion 671a1 and the concave portion 664 come into contact with each other, the force acting in the radial direction with respect to the rotation axis of the displacement member 670 can be held. As a result, damage to the shaft support hole 671a or the color C can be suppressed.

[0445] A through hole 671d1 penetrating in the longitudinal direction on the longitudinal side of the extending member 671 is formed in the protrusion 671d. The through hole 671d1 is a hole through which torsion springs SP1 and SP2 described later are inserted, and is formed larger than the outer diameter of the torsion springs SP1 and SP2.

[0446] The elastic member 671f is arranged on the side surface of the extending member 671 on the approaching direction side of the pair of displacement members 670 arranged in a vertical pair described later. Also, when the upper and lower extending members 671 are arranged at positions close to each other, it is set to a size such that the side surfaces of the elastic members 671f of each other come into contact. Thereby, the impact when the pair of upper and lower displacement members 670 are displaced to positions close to each other can be absorbed.

[0447] The drive means 680 is means for transmitting the power of the drive motor KM3 to the displacement member 670. The drive means 680 mainly includes a gear 682 connected to the shaft of the drive motor KM3, a large-diameter gear 683 meshing with the gear 682, a first link member 684 formed on a rod-shaped body and having one end connected to the side surface of the large-diameter gear 683 and the other end connected to the displacement member 670, a connecting rod 681 for transmitting power to the opposite side with the base member 660 interposed therebetween, a cam member 685 connected to and rotating with the connecting rod 681, and a second link member 686 formed on a rod-shaped body and having one end rotatably connected to the cam member 685 and the other end connected to the displacement member 670.

[0448] The gear 682 is connected to the shaft of the drive motor KM3 as described above and is rotated by the rotation of the drive motor KM3.

[0449] The large-diameter gear 683 is formed in a circular shape in side view, and includes a gear surface 683a formed on the tooth surface that meshes with the gear 682, and a protrusion 683b that protrudes annularly on the side surface in the rotational axis direction thereof. Since the gear surface 683a of the large-diameter gear 683 meshes with the gear 682, the large-diameter gear 683 is rotated when the gear 682 is rotated. That is, it is rotated when the drive motor KM3 is rotationally driven.

[0450] The protrusion 683b is formed to protrude annularly, and its axis is arranged at a position different from the rotational axis of the large-diameter gear 683. Therefore, when the large-diameter gear 683 is rotationally displaced, the protrusion 683b is rotationally displaced on a circle centered on its rotational axis.

[0451] The first link member 684 is formed as a rod-shaped body, and insertion holes 684a and 684b that penetrate in the left-right direction are formed at both ends thereof.

[0452] The insertion hole 684a is a hole into which the protrusion 683b of the large-diameter gear 683 is inserted, and is formed to have an inner diameter larger than the outer diameter of the protrusion 683b. By inserting the protrusion 683b into the insertion hole 684a and fastening the tip of the protrusion 683b with a screw having a head outer diameter larger than the inner diameter of the insertion hole 684a, the first link member 684 can be connected to the large-diameter gear 683 in a rotatable state.

[0453] The insertion hole 684b is a hole into which the connection protrusion 671b of the displacement member 670 is inserted, and is formed to have an inner diameter larger than the outer diameter of the connection protrusion 671b. By inserting the connection protrusion 671b into the insertion hole 684b and fastening the tip of the connection protrusion 671b with a screw having a head outer diameter larger than the inner diameter of the insertion hole 684b, the first link member 684 can be connected to the displacement member 670 in a rotatable state.

[0454] Therefore, when the large-diameter gear 683 is rotated via the gear 682, with the rotation displacement of the large-diameter gear 683, the projection 683b is rotationally displaced about the rotation axis of the large-diameter gear 683, and the first link member 684 having one end connected to the projection 683b is displaced, causing the displacement member 670 connected to the other end of the first link member 684 to be displaced.

[0455] One end of the connecting rod 681 is inserted into the insertion hole 663 of the base member 660 disposed on the left side in the front view, and is fitted inside the rotation axis portion of the large-diameter gear 683. On the other hand, the other end of the connecting rod 681 is connected to the cam member 685. Therefore, by the rotational drive of the drive motor KM3, the connecting rod 681 rotates and the cam member 685 is rotated.

[0456] The cam member 685 is formed in a circular shape in the side view, and the connecting rod 681 is fitted inside its axis portion. Further, the cam member 685 includes a projection 685a that protrudes annularly outward from the side surface in its axial direction. The projection 685a is formed to protrude annularly, and its axis is disposed at a position different from the rotation axis of the cam member 685. Therefore, when the cam member 685 is rotationally displaced, the projection 685a is rotationally displaced on a circle centered on its rotation axis.

[0457] The second link member 686 is formed in the same shape as the shape of the first link member 684 but reversed left and right. The second link member 686 is provided with insertion holes 686a and 686b at both ends in its longitudinal direction.

[0458] The insertion hole 686a is a hole into which the projection 685a of the cam member 685 is inserted, and is formed with an inner diameter larger than the outer diameter of the projection 685a. By inserting the projection 685a into the insertion hole 686a and fastening it with a screw having a head diameter larger than the inner diameter of the insertion hole 686a at the tip of the projection 685a, the second link member 686 can be connected to the cam member 685 in a rotatable state.

[0459] The insertion hole 686b is a hole into which the connecting protrusion 671b of the displacement member 670 is inserted, and is formed with an inner diameter larger than the outer diameter of the connecting protrusion 671b. When the connecting protrusion 671b is inserted into the insertion hole 686b and the tip of the connecting protrusion 671b is fastened with a screw having a head diameter larger than the inner diameter of the insertion hole 684b, the second link member 686 can be connected to the displacement member 670 in a rotatable state.

[0460] Therefore, when the cam member 685 is rotated via the connecting rod 681, as the cam member 685 rotates and displaces, the protrusion 685a rotates and displaces about the rotation axis of the cam member 685, and the second link member 686 having one end connected to the protrusion 685a displaces, causing the displacement member 670 connected to the other end of the second link member 686 to displace.

[0461] That is, it is performed by the displacement of the displacement member 670, the first link member 684, and the second link member 686. Here, since the operations of the first link member 684 and the second link member 686 are synchronized via the connecting rod 681, it is possible to suppress the tilting when the displacement member 670 displaces. As a result, the displacement member 670 can be displaced smoothly.

[0462] Next, with reference to FIGS. 51 to 53, a detailed description of the displacement member 670 will be given. FIG. 51(a) is a front view of the displacement member 670, and FIG. 51(b) is a side view of the displacement member 670. FIG. 52 is an exploded perspective front view of the displacement member 670. FIG. 53 is a cross-sectional view of the displacement member 670 taken along line LIII-LIII of FIG. 51(a).

[0463] As described above, the displacement member 670 is formed by including an extended member 671 pivotally supported on the base member 660 in a rotatable manner, and a decorative unit 672 connected to the extended member 671.

[0464] As shown in FIGS. 51 to 53, the extension member 671 includes a connecting portion 671c formed in a plate shape on the short side (the connecting side of the decorative unit 672). On the surfaces of the connecting portions 671c of the pair of extension members 671 arranged on the left and right that face each other, stepped portions 671c1 that partially project in a stepped shape are formed. The stepped portions 671c1 are formed alternately on the left and right, and the stepped portions 671c1 of each other are in a state of meshing with a predetermined gap therebetween. Thereby, dimensional errors can be absorbed when the extension member 671 is molded.

[0465] The decorative unit 672 includes an LED that irradiates light inside, and is a unit that irradiates light to the player side. The decorative unit 672 is mainly formed by including a rear cover 673 disposed on the rear side, a front cover 676 that covers the rear cover 673 and is disposed on the front side of the rear cover 673, a base member 674 disposed between the rear cover 673 and the front cover 676, and a diffusion member 675 and a lens member 677 disposed between the base member 674 and the front cover 676.

[0466] The rear cover 673 is formed in a horizontally long rectangular plate-like body when viewed from the front, and the connecting portion 671c of the extension member 671 is fastened to the rear side. Thereby, the decorative unit 672 and the extension member 671 can be fastened.

[0467] Further, the rear cover 673 is formed of a resin material that is difficult to transmit light (opaque). The rear cover 673 includes a reflecting portion 673a that is recessed on the rear side at a position facing the diffusion member 675 described later.

[0468] The reflecting portion 673a is formed across the lower edge portion of the rear cover 673 in the left-right direction, and a white coating with a high light reflectance is applied to the inner surface thereof. Thereby, the light irradiated inside the reflecting portion 673a can be reflected inside the reflecting portion 673a and irradiated to the diffusion member 675 side.

[0469] The front cover 676 is formed such that its front view shape is substantially the same as that of the back cover 673, and is disposed in a manner to cover the front side of the back cover 673. Further, the front cover 676 is formed of a resin material capable of transmitting light, and can emit the light emitted from the first LED 674a and the second LED, which will be described later, to the front side (the player side).

[0470] The base member 674 is formed into a horizontally long rectangular plate-like body that is smaller than the back cover 673 in a front view. On the front side of the base member 674, a first LED 674a that is arranged side by side in the left-right direction at the lower edge portion and irradiates light toward the diffusion member 675, and a second LED 674b that is arranged above the first LED 674a and irradiates light toward the lens member 677 are mainly provided and formed.

[0471] The first LED 674a is disposed at a position facing the upper end portion of the diffusion member 675 and is disposed so as to be able to irradiate light downward of the base member 674. Thereby, it is possible to suppress the light irradiated from the first LED 674a from entering the lens member 677, which will be described later. As a result, it becomes easier for the player to distinguish between the light emitted to the front side through the diffusion member 675 and the light emitted to the front side through the lens member 677, and it is possible to suppress the player's interest from being impaired.

[0472] The second LED 674b is disposed above the first LED 674a. Therefore, the light of the second LED 674b can be made to enter the lens member 677 disposed at the upper portion of the diffusion member 675.

[0473] The diffusion member 675 is formed from a horizontally long rectangular plate-like body in a front view and is disposed at the lower end portion on the back side of the front cover 676. The diffusion member 675 is formed of an opalescent resin material capable of diffusing the light incident therein. Thereby, the light emitted from the first LED 674a and incident on the diffusion member 675 can be diffused to uniformize the light as a whole and emitted to the front side (the player side).

[0474] The lens member 677 is formed from a horizontally long rectangular plate-like body and is disposed at the upper end portion on the back side of the front cover 676. The lens member 677 is formed from a transparent resin material, and a plurality of protrusions are formed on the back side (not shown). Thereby, the light emitted from the second LED 674b can be easily made to enter the inside by the protrusions on the back side. As a result, even if the amount of light emitted from the second LED 674b is reduced, light can be made to enter the lens member 677, and light can be emitted to the front side (player side) of the front cover 676.

[0475] Next, with reference to FIG. 54, the mode of the light emitted to the front side (player side) of the front cover 676 by the first LED 674a will be described. FIG. 54 is a front view of the displacement member 670. In FIG. 54, the region of the light emitted to the player side by the first LED 674a is shown by a two-dot chain line, and the symbol of the irradiation region SR2 is shown.

[0476] As shown in FIG. 54, the region of the light emitted to the player side by the first LED 674a is formed in a horizontally long rectangular shape at the lower end portion of the decoration unit 672 (front cover 676). Since the displacement member 670 is disposed at both the upper and lower ends of the vertical displacement unit 600L, the displacement member 670 forms the irradiation region SR2 at positions separated by a predetermined distance in the vertical direction. Therefore, the upper and lower displays of numbers by the 7-segment display can be performed by the irradiation regions SR2 of the pair of upper and lower displacement members 670.

[0477] Next, with reference to FIGS. 55 and 56, the 7-segment display performed by the segment display device 600 and the decorative symbol display device 800 will be described. FIG. 55 is a front view of the segment display device 600 and the decorative symbol display device 800. FIG. 56 is a schematic diagram of the segment display device 600 and the decorative symbol display device 800. In FIGS. 55 and 56, the state where the transmission region 821b1 of the outer reel 821 is rotated to the player side is shown, and the irradiation region SR1, the irradiation region SR2, and the transmission region 821b1 are shown by two-dot chain lines.

[0478] As shown in FIG. 55, the irradiation region SR1 formed by the first segment unit 610 and the second segment unit 620 of the segment display device 600 is formed in two rows in the vertical direction and six columns in the horizontal direction.

[0479] The irradiation region SR1 is formed in groups of four with the decoration pattern display device 800 sandwiched therebetween, and three such groups are arranged side by side in the horizontal direction. Between each group of the irradiation regions SR1, the irradiation region SR2 is arranged vertically, and the transmission region 821b1 is arranged at the vertical middle position. Therefore, the numbers by the 7-segment display can be displayed by the seven irradiation regions SR1, SR2 and the transmission region 821b1.

[0480] As described above, since the four in a group of the irradiation regions SR1 are arranged side by side in three groups in the horizontal direction, the 7-segment display is formed in each group. That is, the 7-segment displays are arranged side by side in three in the horizontal direction.

[0481] Therefore, the numbers can be displayed with the 7-segment displays arranged side by side in the horizontal direction as the effective lines for the jackpot lottery of the pachinko machine 10 (for example, the "7" segment display is made for all the 7-segment displays). As a result, not only the jackpot display by the above-described decoration pattern display device 800 but also the jackpot display by the 7-segment display can be made. As a result, since the player can visually recognize a plurality of display forms, the player's interest can be improved.

[0482] Here, since the light transmission portions 621a of the first segment unit 610 and the second segment unit 620 of the segment display device 600 are curved in a convex shape on the front side, when the player visually recognizes the 7-segment display, the display at the vertical center portion closer to the player becomes larger, and the displays at both vertical end portions farther from the player become smaller. Therefore, there has been a problem that the display of the numbers by the 7-segment cannot be clearly visually recognized by the player.

[0483] In contrast, in the present embodiment, as shown in FIG. 56, as the 7-segment display extends from the upper and lower central positions toward the upper and lower ends, the width dimension in the left-right direction is sequentially increased. As a result, the displays by the 7-segment at the upper and lower ends and the upper and lower central positions can be made uniform as a whole. Consequently, the display of numbers by the 7-segment can be clearly visible to the player.

[0484] Furthermore, in the 7-segment displays formed on both the left and right sides, the central portion in the up-down direction is formed to be inclined toward the central side in the left-right direction. This enables the player to clearly view the 7-segment displays formed on both the left and right sides.

[0485] That is, the player's viewpoint is located at the central position in the left-right direction of the normal pachinko machine 10. Also, the segment display device 600 is disposed at the central position in the left-right direction of the pachinko machine 10. Therefore, the player's viewpoint is positioned in front of the 7-segment displayed at the center. Accordingly, as the distance from the player's viewpoint increases left and right, due to the curved shape of the light transmission portion 621a of the first segment unit 610 and the second segment unit 620, the 7-segment display is visually recognized by the player in a curved manner. Since the central portion in the up-down direction of the 7-segment display is formed to be inclined toward the central side in the left-right direction, it is difficult for the 7-segment display to be visually recognized in a curved manner from the player's viewpoint. As a result, the player can clearly view the 7-segment display.

[0486] Next, with reference to FIGS. 57 to 60, the displacement mode of the displacement member 670 will be described. FIGS. 57(a) to G01(c) are front views of the up-down displacement unit 600L. FIGS. 58(a), 59(a), and 60(a) are side views of the up-down displacement unit 600L, and FIGS. 58(b), 59(a), and 60(b) are cross-sectional views of the up-down displacement unit 600L taken along the line LVIIIb-LVIIIb in FIG. 57(a).

[0487] In FIGS. 57(a), 58(a), and 58(b), the state where the displacement member 670 is disposed in the retracted state is illustrated. In FIGS. 57(b), 59(a), and 59(b), the state where the displacement member 670 is disposed in the intermediate state is illustrated. In FIGS. 57(c), 60(a), and 60(b), the state where the displacement member 670 is disposed in the protruding state is illustrated.

[0488] Further, the retracted state of the displacement member 670 is a state where the pair of displacement members 670 disposed vertically are separated from each other vertically outward. The protruding state of the displacement member 670 is a state where the pair of displacement members 670 disposed vertically are in contact with each other at the vertical intermediate position. The intermediate state of the displacement member 670 is a state where the displacement member 670 is disposed between the retracted state and the protruding state.

[0489] As shown in FIGS. 57(a) and 58, at the position where the displacement member 670 is in the retracted state, among the pair of displacement members 670 disposed vertically, the upper displacement member 670 (upper in FIG. 57) has the first link member 684 and the second link member 686 positioned upward, so that the decorative unit 672 is positioned upward with the pivot hole 671a as the rotation axis.

[0490] Also, the torsion spring SP1 inserted into the through hole 671d1 of the upper displacement member 670 has an engagement position with the through hole 671d1 at the proximal end portion on the other end side (the side inserted into the through hole 671d1). Therefore, the biasing force applied by the torsion spring SP1 can be increased. As a result, it is easy to maintain the state where the decorative unit 672 is disposed above the displacement member 670 in the gravitational direction.

[0491] On the other hand, among the pair of displacement members 670 disposed vertically, the lower displacement member 670 (lower in FIG. 57) has the first link member 684 and the second link member 686 positioned downward, so that the decorative unit 672 is positioned downward with the pivot hole 671a as the rotation axis.

[0492] In addition, for the torsion spring SP2 inserted into the through hole 671d1 of the displacement member 670 disposed below, the engagement position with the through hole 671d1 is the proximal end portion on the other end side (the side inserted into the through hole 671d1). Therefore, the biasing force applied by the torsion spring SP2 can be increased. As a result, it becomes easier to displace the decoration unit 672 of the displacement member 670 upward in the gravitational direction.

[0493] In the retracted state, an opening is formed between the opposing decoration units 762 of the pair of upper and lower displacement members 670, and the decoration pattern display device 800 disposed inside the vertical displacement unit 600L can be visually recognized. In this case, as described above, three patterns decorated on the inner reel 811 of the decoration pattern display device 800 can be displayed in the vertical direction on the player side.

[0494] When a driving force of rotation is applied to the drive motor KM3 from the states shown in FIGS. 57(a) and 58, the large-diameter gear 683 and the cam member 685 are rotated. As a result, the first link member 684 and the second link member 686 are displaced to substantially the central position in the vertical direction of the vertical displacement unit 600L. Accordingly, the displacement member 670 connected to the insertion holes 684b and 686b of the first link member 684 and the second link member 686 is rotationally displaced about the shaft support hole 671a, and is displaced to the states shown in FIGS. 57(c) and 60 via the states shown in FIGS. 57(b) and 59.

[0495] As shown in FIGS. 57(b) and 59, when the displacement member 670 is displaced to the intermediate position, the engagement position of the torsion spring SP1 inserted into the through hole 671d1 of the displacement member 670 disposed above with the through hole 671d1 is the intermediate position on the other end side (the side inserted into the through hole 671d1). Therefore, the biasing force of the torsion spring SP1 can be increased by the amount of deformation of the torsion spring SP1, and the biasing force of the torsion spring SP1 can be made smaller than the engagement position in the retracted state by changing the engagement position.

[0496] Also, similar to the torsion spring SP1 inserted into the through hole 671d1 of the displacement member 670 disposed on the lower side, the engagement position with the through hole 671d1 is set to an intermediate position on the other end side (the side inserted into the through hole 671d1). Therefore, the biasing force of the torsion spring SP2 can be reduced by the amount of deformation of the torsion spring SP2, and the biasing force of the torsion spring SP1 can be made smaller than the engagement position in the retracted state by changing the engagement position.

[0497] In the intermediate state, an opening smaller than that in the retracted state is formed between the opposing decorative units 762 of the pair of upper and lower displacement members 670, and the decorative pattern display device 800 disposed inside the upper and lower displacement units 600L can be visually recognized. In this case, one pattern decorated on the inner reel 811 of the decorative pattern display device 800 can be displayed on the player side.

[0498] Therefore, by displacing the displacement member 670 from the retracted state in which three patterns decorated on the inner reel 811 are displayed in the vertical direction to the intermediate state in which one pattern decorated on the inner reel 811 is displayed in the vertical direction, a plurality of production modes can be formed and the player's interest can be improved. Further, by adopting a mode in which one pattern decorated on the inner reel 811 is displayed in the vertical direction, one pattern can be made to attract the player's attention. Therefore, since the part to be focused on can be clarified, it is easy for the player to visually recognize the production. As a result, it is possible to suppress a decrease in the player's interest.

[0499] As shown in FIGS. 57(c) and 60, when the displacement member 670 is displaced to the position in the retracted state, the engagement position of the torsion spring SP1 inserted into the through hole 671d1 of the displacement member 670 disposed above with the through hole 671d1 is set to the tip position on the other end side (the side inserted into the through hole 671d1). Therefore, the biasing force of the torsion spring SP1 can be increased by the amount of deformation of the torsion spring SP1, and the biasing of the torsion spring SP1 can be made smaller than the engagement position in the intermediate state by changing the engagement position.

[0500] Also, similar to the torsion spring SP1, the torsion spring SP2 inserted into the through hole 671d1 of the displacement member 670 disposed on the lower side has an engagement position with the through hole 671d1 at the tip position on the other end side (the side inserted into the through hole 671d1). Therefore, the biasing force of the torsion spring SP2 can be increased by the amount of deformation of the torsion spring SP2, and the biasing force of the torsion spring SP1 can be made smaller than that at the intermediate engagement position by changing the engagement position.

[0501] That is, the biasing forces of the torsion springs SP1 and SP2 can be made non-linear as the displacement member 670 is displaced. As a result, depending on the displacement position of the displacement member 670, the necessary biasing force can be easily applied from the torsion springs SP1 and SP2. Consequently, the energy required for driving the drive motor KM3 can be minimized.

[0502] In the protruding state, the decoration units 672 of the pair of upper and lower displacement members 670 are abutted at the intermediate position in the vertical direction of the vertical displacement unit 600L. In this case, the decoration unit 672 is disposed on the front side of the decoration pattern display device 800, and the display of the decoration pattern display device 800 can be made invisible from the player side (front side).

[0503] Therefore, by setting the displacement member 670 in the protruding state, rotating and displacing the inner reel unit 810 and the outer reel unit 820, and then displacing the displacement member 670 to the intermediate state or the retracted state, it is easy to give the player a sense of expectation that the symbols will align (a big win lottery has been drawn). As a result, the player's interest can be enhanced.

[0504] In the above embodiment, the case where the pair of upper and lower displacement members 670 are displaced by the same amount has been described, but the present invention is not limited to this. It is also possible to rotationally drive one of the two drive motors KM3 provided, and displace only one side of the pair of upper and lower displacement members 670 to the intermediate state or the protruding state position.

[0505] Further, the maximum displacement amount of the displacement members 670 arranged in an upper and lower pair is not set to the intermediate position, but can be displaced beyond the position shown in FIG. 60. That is, the pair of displacement members 670 can be displaced vertically in a state of being in contact with each other.

[0506] Next, with reference to FIGS. 61 to 63, the operation of the vertical displacement unit 600L will be described. FIGS. 61 to 63 are schematic views of the vertical displacement unit 600L. In FIGS. 61 to 63, the transition states of the displacement members 670 are illustrated in order.

[0507] In FIGS. 61 to 63, a U is added to the end of the reference numeral of the displacement member 670 disposed on the upper side of the vertical displacement unit 600L and the driving means for driving the displacement member 670, and a D is added to the end of the reference numeral of the displacement member 670 disposed on the lower side of the vertical displacement unit 600L and the driving means for driving the displacement member 670 for explanation.

[0508] As shown in FIG. 61, in the vertical displacement unit 600L, extension members 671 of the displacement member 670 are disposed on both the left and right sides. The pair of extension members 671 are respectively connected to either the driven side to which the driving force of the drive motor KM3 is transmitted via the connecting rod 681 or the driving side to which the driving force of the drive motor KM3 is transmitted by the protrusion 683b of the large-diameter gear 683.

[0509] As shown in FIG. 62, when the displacement members 670 arranged vertically are displaced, the side surfaces of the respective decorative units 672 are brought into contact with each other at the vertical center position of the vertical displacement unit 600L.

[0510] As shown in FIG. 63, by displacing both of the displacement members 670 in the same direction from the state shown in FIG. 62, it is possible to displace them in the vertical direction with the side surfaces of the respective decorative units 672 being in contact with each other.

[0511] Here, there is known a gaming machine including a first displacement member (decoration unit 672U) and a second displacement member (decoration unit 672D) which are arranged to face each other and are each formed to be displaceable in a direction of approaching or separating from each other, and are formed to be displaceable in the same direction with opposite sides in contact with each other. According to such a gaming machine, by bringing the first displacement member and the second displacement member close to each other to a position where the opposite sides are in contact with each other, an object (for example, a liquid crystal display device or an effect member) located on the back side of the first displacement member and the second displacement member is shielded, and by displacing the first displacement member and the second displacement member in a direction of separating from each other, an effect of releasing the shielding and making the object visible can be performed along with the displacement. Further, by displacing the first displacement member and the second displacement member in the same direction (for example, reciprocally displacing in one direction and the other direction) with the opposite sides in contact with each other, an effect before releasing the shielding (an effect that draws attention to the shielding release operation) can be performed while maintaining the shielding of the object.

[0512] However, in the above-described conventional gaming machine, due to dimensional tolerances and assembly tolerances of the constituent members, it is difficult to bring the opposite sides of the first displacement member and the second displacement member into close contact with each other, and there is a problem that a gap may be formed between the opposite sides. If a gap is formed between the opposite sides, the player can visually recognize the object on the back side through the gap, and the effect is inhibited.

[0513] In contrast, according to the present embodiment, a base member 660, driving means 680U and driving means 680D for displaceably supporting a decoration unit 672U and a decoration unit 672D on the base member 660 are provided. The support mode of the driving means 680U is biased to one side of the opposing side of the decoration unit 672U, and is on the side opposite to the other side of the opposing side of the decoration unit 672D that abuts on one side of the opposing side of the decoration unit 672U. Therefore, in a state where the opposing sides of the decoration unit 672U and the decoration unit 672D are in contact with each other, the support mode of the driving means 680U and the support mode of the driving means 680D can be biased to opposite sides (sides rotated 180° around the center of rotation at the center of one side and the other side of the opposing side). As a result, it is possible to easily bring the opposing sides of the decoration unit 672U and the decoration unit 672D into close contact with each other, and it is possible to suppress the formation of a gap between the opposing sides (see FIG. 63).

[0514] In the present embodiment, since the number of disposed components is different on one side and the other side (both sides in the left - right direction), the driving forces transmitted to the left and right of the decoration unit 672 are different, and the driving means 680U and the driving means 680D can face the side with lower rigidity (higher rigidity) of the other with the side with higher rigidity (lower rigidity) of themselves. Therefore, in a state where the opposing sides of the decoration unit 672U and the decoration unit 672D are in contact with each other, each of the driving means 680U and the driving means 680D can form a state where it pushes (advances) the other on the side with higher rigidity and accepts (recedes) the other on the side with lower rigidity. As a result, it is possible to easily bring the opposing sides of the decoration unit 672U and the decoration unit 672D into close contact with each other, and it is possible to suppress the formation of a gap between the opposing sides.

[0515] The driving means 680U includes a driving motor KM3U that generates a driving force, a pair of extending members 671U that connect the decorative unit 672U to the base member, and a first link member 684U and a second link member 686U that transmit the driving force of the driving motor KM3U to the pair of extending members 671U respectively and have different configurations. The driving means 680D includes a driving motor KM3D that generates a driving force, a pair of extending members 671U that connect the decorative unit 672D to the base member 660, and a second link member 686D and a first link member 684D that transmit the driving force of the driving motor KM3U to the pair of extending members 671U respectively and have different configurations. Therefore, it is easy to bring the opposing sides of the decorative unit 672U and the decorative unit 672D into close contact with each other, and it is possible to suppress the formation of a gap between the opposing sides.

[0516] That is, in a state where the opposing sides of the decorative unit 672U and the decorative unit 672D are in contact with each other, each of the driving means 680U and the driving means 680D can, for example, push in (advance) the other party on the side with a large driving force or an earlier driving force transmission timing, and accept (recede) the other party on the side with a small driving force or a later driving force transmission timing, thereby forming a state. As a result, it is easy to bring the opposing sides of the decorative unit 672U and the decorative unit 672D into close contact with each other, and it is possible to suppress the formation of a gap between the opposing sides.

[0517] In addition, the extending members 671U and the extending members 671D are formed to have substantially the same length as each other, one end side is connected to the decorative unit 672U or the decorative unit 672D, and the other end side is pivotally supported on the base member 660 so as to be rotatable coaxially. Therefore, when reciprocating the decorative unit 672U and the decorative unit 672D in the same direction while bringing their opposing sides into contact with each other, even when using the bias of the support mode, it is easy to maintain the state where the opposing sides are in contact with each other.

[0518] Furthermore, an elastic member 671f formed of a rubber-like elastic material is disposed on the extension member 671U or the extension member 671D. When the decorative units 672U and 672D are in contact with each other at their opposing sides, the elastic body is interposed between the extension member 671U and the extension member 671D in an elastically compressed state. Therefore, when the decorative units 672U and 672D are reciprocally moved in the same direction while keeping their opposing sides in contact with each other, even when taking advantage of the bias of the support mode, it is possible to easily maintain the state where the opposing sides are in contact with each other.

[0519] Also, as described above, the driving means 680U includes a drive motor KM3U that generates a driving force, a pair of extension members 671U that are driven by the drive motor KM3U and connect the decorative unit 672U to the base member 660, and two torsion springs SP1 that apply different biasing forces to the pair of extension members 671U respectively. The driving means 680D includes a drive motor KM3D that generates a driving force, a pair of extension members 671D that are driven by the drive motor KM3D and connect the decorative unit 672D to the base member 660, and two torsion springs SP2 that apply different biasing forces to the pair of extension members 671D respectively. Therefore, it is possible to easily bring the opposing sides of the decorative unit 672U and the decorative unit 672D into close contact with each other and suppress the formation of a gap between the opposing sides.

[0520] That is, when the opposing sides of the decorative unit 672U and the decorative unit 672D are in contact with each other, each of the driving means 680U and the driving means 680D can form a state where, for example, it pushes in (advances) the other on the side with a large biasing force and accepts (recedes) the other on the side with a small biasing force. As a result, it is possible to easily bring the opposing sides of the decorative unit 672U and the decorative unit 672D into close contact with each other and suppress the formation of a gap between the opposing sides.

[0521] Incidentally, the two torsion springs SP1 may have the same configuration. That is, even if the positions where the biasing force acts are different from each other, or the amounts of elastic deformation are different from each other, the biasing forces applied to the pair of extending members 671U may be made different. The same applies to the two torsion springs SP2.

[0522] Furthermore, the driving means 680U includes a driving motor KM3U that generates a driving force, a pair of extending members 671U that are driven by the driving motor KM3U and connect the decorative unit 672U to the base member 660, and a first biasing member that applies a biasing force to one of the pair of extending members 671U. The driving means 680D includes a driving motor KM3D that generates a driving force, a pair of extending members 671D that are driven by the driving motor KM3D and connect the decorative unit 672D to the base member 660, and a second biasing member that applies a biasing force to one of the pair of extending members 671D. Therefore, it is possible to easily bring the opposing sides of the decorative unit 672U and the decorative unit 672D into close contact with each other, and it is possible to suppress the formation of a gap between the opposing sides.

[0523] That is, in a state where the opposing sides of the decorative unit 672U and the decorative unit 672D are in contact with each other, each of the driving means 680U and the driving means 680D can form a state in which, for example, it pushes in (advances) the other on the side where the biasing force acts and accepts (recedes) the other on the side where the biasing force does not act. As a result, it is possible to easily bring the opposing sides of the decorative unit 672U and the decorative unit 672D into close contact with each other, and it is possible to suppress the formation of a gap between the opposing sides.

[0524] As described above, since the torsion spring SP1 is formed as a torsion spring, one leg thereof is connected to the extension member 671U and the other leg is connected to the base member 660, and the torsion spring SP1 applies a biasing force in the direction of bringing the decorative unit 672U closer to the decorative unit 672D, when the decorative unit 672U is displaced in the direction of approaching the decorative unit 672D, the driving force of the drive motor KM3U required to rotate the extension member 671U can be assisted by the biasing force of the torsion spring SP1. Therefore, for example, when the decorative unit 672U is displaced from the retracted position separated from the decorative unit 672D to the contact position in contact with the decorative unit 672D from the stopped state, the start of the displacement can be performed smoothly.

[0525] In this case, as the extension member 671U rotates in the direction of bringing the decorative unit 672U closer to the decorative unit 672D, at least one of the connection position between one leg of the torsion spring SP1 and the extension member 671U or the connection position between the other leg of the torsion spring SP1 and the base member 660 is separated from the winding portion. Therefore, the biasing force in the direction of bringing the decorative unit 672U closer to the decorative unit 672D can be weakened by the increase in the distance from the winding portion to the force acting position. Therefore, for example, when stopping the decorative unit 672U brought closer to the decorative unit 672D, the stop of the displacement can be surely performed, so that damage due to collision can be suppressed. Further, when the decorative unit 672U and the decorative unit 672D are reciprocally displaced in the same direction with the opposing sides in contact with each other, the driving force required for the reciprocal displacement can be suppressed, so that the displacement speed of the reciprocal displacement can be increased and the production effect can be improved.

[0526] On the other hand, there is provided a torsion spring SP2 formed as a torsion spring, with one leg connected to the extension member 671D and the other leg connected to the base member, which applies a biasing force in a direction to bring the decorative unit 672D closer to the decorative unit 672U. As the extension member 671D rotates in a direction to bring the decorative unit 672D closer to the decorative unit 672U, at least one of the connection position between one leg of the torsion spring SP2 and the extension member 671D or the connection position between the other leg of the torsion spring SP2 and the base member is separated from the winding portion. Therefore, the torsion spring SP2 exhibits the same effect as the torsion spring SP1. In particular, when the decorative unit 672U and the decorative unit 672D are reciprocally displaced in the same direction with their opposing sides in contact, the driving force required for the reciprocal displacement can be suppressed in both of them, which is particularly effective. Also, when the decorative unit 672U and the decorative unit 672D are positioned at the same height (arranged in the gravitational direction position), the contact position between the two is the highest position (or the lowest position) in the gravitational direction, and the separated position (retracted position) between the two is the lowest position (or the highest position) in the gravitational direction, the configurations of the torsion spring SP1 and the torsion spring SP2 are particularly effective.

[0527] Since the decorative unit 672U is brought closer to the decorative unit 672D by displacement i...
