Description

Technical Field

[0001] The present invention relates to a gaming machine in which a large number of gaming pins are provided on a game board having a game area on the front side where game balls can flow down.

Background Art

[0002] A pachinko machine, which is a typical gaming machine, has a game board with a game area on the front side where pachinko balls (game balls) can flow down, and has a normal winning hole and a start winning hole (start winning means) where pachinko balls can win, and a display device (display means) such as a liquid crystal type or a drum type that variably displays a production design (so-called decorative figure) to perform a figure variation production. Further, in the game area, a large number of game pins implanted on the front surface of the game board are scattered while avoiding the arrangement areas of game members such as winning members and decorative bodies (see, for example, Patent Document 1). In the pachinko machine, the pachinko balls launched into the game area bounce off while coming into contact with the game pins and game members in the game area and gradually flow down by their own weight, and by winning the start winning hole in the process of flowing down the game area, various game productions such as a reach production accompanying a figure variation are performed by the display device, and when the figure stops at a predetermined combination on the display device, a so-called jackpot occurs, and a special winning device provided on the game board is opened so that a large number of prize balls can be obtained.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In pachinko machine manufacturers, the intervals between pins and driving angles of a plurality of game pins are adjusted so that game performance such as the winning rate and the ball launching rate becomes values preset in the pachinko machine before shipment. However, if the intervals between pins and driving angles of a plurality of game pins are adjusted excessively at a game parlor such that game balls do not enter a winning opening or the like at all, there is a problem that the intended game performance preset in the pachinko machine cannot be exhibited.

[0005] That is, in view of the above problems inherent in the gaming machines according to the prior art, the present invention has been proposed to preferably solve these problems, and an object thereof is to provide a gaming machine that makes it difficult to adjust game pins and can maintain the intended game performance.

Means for Solving the Problems

[0006] In order to solve the above problems and achieve the intended object, The first means is, In a gaming machine in which a game board (20) having a game area (26) through which game balls can flow down is formed on the front side, and a plurality of game pins (23A to 23J, 56) facing the game area (26) are provided, a regulating member (37, 49, 55) that regulates a displacement of the game pins (23A to 23J, 56) by a predetermined amount or more in a direction intersecting the extending direction of the game pins (23A to 23J, 56) is detachably provided, an index surface (39a to 42a, 51a, 52a, 58a) that is located on the side of the game pins (23A to 23J, 56) in the regulating member (37, 49, 55) and can identify the distance from the game pins (23A to 23J, 56) is located at a predetermined interval from the game pins (23A to 23J, 56), The gist is that the regulating member (37, 49, 55) is formed of a transparent material. By restricting the displacement of the game pins with a restricting member in this way, it becomes difficult to adjust the game pins, and the intended game performance can be maintained. Further, since the restricting member is detachable, maintenance such as replacement of the restricting member can be easily performed. Furthermore, it is possible to easily determine whether the game pins are arranged at appropriate positions based on changes in the distance between the reference surface of the restricting member and the game pins. Moreover, since the restricting member is transparent, the movement of the game balls is not made difficult to see by the member that restricts the displacement of the game pins, and there is no risk of giving the player a sense of distrust.

Advantages of the Invention

[0007] According to the gaming machine of the present invention, it is possible to make it difficult to adjust the game pins and maintain the intended game performance.

On the front side of the game board 20, as shown in FIG. 2, a game area 26 is defined by a substantially circular guide rail 21 disposed on the front surface (board surface) through which the pachinko balls can flow down (move). The game is played by hitting the pachinko balls fired from the hitting and launching device into the game area 26. Further, an installation member (not shown) that defines an accommodation space is disposed on the game board 20. In the accommodation space, various effect means such as a light-emitting effect device that performs effects by light emission and a movable effect device that performs effects by the movement of a movable body are installed. Note that the display device 17 is attached to the back side of the installation member and is configured to face the front side of the game board 20 so as to be visible through an opening (visible part) provided in the installation member and an opening 25a of a frame-shaped decorative body 25 (described later) as described later. Note that the game board 20 may be a non-light-transmissive plate member such as a veneer material or a synthetic resin material with a decorative sticker or the like attached to its surface.

[0014] A plurality of mounting openings penetrating through the front and rear are formed in the game area 26 of the game board 20, and various game component parts are attached to each mounting opening from the front side. At the lowermost position of the game area 26, an out port 22 that opens to the game area 26 is formed. The pachinko balls that are launched into the game area 26 and enter the out port 22 are configured to be discharged outside the machine. Further, a large number of game pins 23 are provided in the game area 26 of the game board 20, and a rotating guide member 24, also called a so-called "windmill", that rotates when contacted by the pachinko balls flowing down in the game area 26 (first ball flow path 26a) is rotatably supported to the left side of a frame-shaped decorative body 25 described later. The flowing direction of the pachinko balls is configured to change irregularly by contact with the game pins 23 and the rotating guide member 24. Note that the number of formed mounting openings is appropriately determined as needed according to the number and arrangement positions of various game component parts attached to the game board 20.

[0015] In the game board 20 of the embodiment, as shown in FIG. 2, a frame-shaped decorative body 25 having an opening 25a that opens front and back is attached to a mounting opening formed in a substantially central portion of a game area 26 surrounded by the guide rail 21, and a display unit 17a of the display device 17 faces the front side of the game board 20 through the opening 25a of the frame-shaped decorative body 25. The installation member is formed in a box shape that opens forward from a substantially rectangular back plate formed in a shape slightly smaller than the outer shape of the game board 20 and a picture wall portion that protrudes forward from the outer peripheral edge portion of the back plate. With the front end portion of the opening of the picture wall portion in contact with the back surface of the game board 20, the game board 20 and the installation member are fixed by screws. Further, on the back plate of the installation member, a substantially rectangular opening is formed so as to open front and back at a position aligned with the opening 25a of the frame-shaped decorative body 25 in the front-rear direction, and the display device 17 is detachably attached to the back side of the back plate, and the display unit 17a of the display device 17 faces the front side of the game board 20 through the opening.

[0016] (Regarding the frame-shaped decorative body 25) As shown in FIG. 2, the frame-shaped decorative body 25 includes a frame-shaped base portion (not shown) formed in an annular shape extending along the inside of the mounting opening formed in the game board 20, and a frame-shaped base portion provided on the frame-shaped base portion and protruding forward from the front surface of the game board 20, a shade-shaped portion 25b that separates the game area 26 and the display unit 17a of the display device 17 and defines the inner circumference of the game area 26, and a thin plate-shaped base plate portion 25c that extends outward from the rear edge of the shade-shaped portion 25b. Then, with the frame-shaped base portion inserted into the mounting opening and the base plate portion 25c in contact with the front surface of the game board 20, the base plate portion 25c is fixed to the game board 20 by fixing means such as screws, whereby the frame-shaped decorative body 25 is attached to the game board 20. Here, as shown in FIG. 2, the shade-shaped portion 25b is provided so as to continuously extend from a substantially intermediate position on the left side edge of the frame-shaped decorative body 25 (frame-shaped base portion) across the upper edge and the lower right edge, and restricts the flow (fall) of pachinko balls across the opening 25a side, that is, the front side of the display unit 17a in the display device 17.

[0017] As shown in Fig. 2, on the frame-shaped decorative body 25, a stage 25d is provided below the opening 25a, and on the left side of the opening 25a, a ball inlet 25e is provided which opens into the game area 26 (the first ball flow-down path 26a) and guides the pachinko balls flowing down through the game area 26 to the stage 25d. The pachinko balls passed from the ball inlet 25e to the stage 25d roll left and right on the stage 25d and are then discharged to the game area 26 where the first starting winning part 30 described later is arranged. Further, at the rear edge of the stage 25d, a transparent plate 25f is provided which rises upward at a predetermined height across the entire length in the left-right direction, preventing the pachinko balls rolling on the stage 25d from moving toward the display part 17a side of the display device 17.

[0018] The game area 26 defined on the game board 20 is partitioned into a first ball flow-down path 26a where pachinko balls flow down on the left side of the eaves-shaped part 25b in the frame-shaped decorative body 25 and a second ball flow-down path 26b where pachinko balls flow down from above and to the right side of the eaves-shaped part 25b in the frame-shaped decorative body 25. Thereby, by rotating the operation lever 16a of the operation handle 16 to adjust the hitting force, the player can arbitrarily select either a game form (left hitting game form) in which the pachinko balls launched into the game area 26 flow down the first ball flow-down path 26a or a game form (right hitting game form) in which the pachinko balls flow down the second ball flow-down path 26b. And in the pachinko machine 10 according to the embodiment, when the pachinko balls flow down the first ball flow-down path 26a (in the case of the left hitting game form), it is configured such that the possibility of the pachinko balls winning in the first starting winning part 30 described later is higher compared to when the pachinko balls flow down the second ball flow-down path 26b, and when the pachinko balls flow down the second ball flow-down path 26b (in the case of the right hitting game form), it is configured such that the possibility of the pachinko balls winning in the gate part 33, the second starting winning part 31, and the special winning part 32 described later is higher compared to when the pachinko balls flow down the first ball flow-down path 26a.

[0019] (Regarding the ball inlet part) As shown in FIG. 2, the game board 20 is provided with a plurality of ball entry parts (specifically, a first start winning part 30, a second start winning part 31, a gate part 33, a special winning part 32, and a normal winning part 34, which will be described later) into which pachinko balls flowing down in the game area 26 can enter. By executing control according to the ball entry part into which the pachinko ball has entered, a predetermined game can be played. Specifically, in the pachinko machine 10 of the embodiment, the first start winning part 30 as the ball entry part is provided at a position where the pachinko ball flowing down the first ball flow path 26a can enter, and the second start winning part 31, the special winning part 32, and the gate part 33 as the ball entry parts are provided at positions where the pachinko balls flowing down the second ball flow path 26b can enter. In addition, in the game board 20 of the embodiment, the normal winning part 34 as the ball entry part is arranged so as to be located in the first ball flow path 26a, and the pachinko ball flowing down the first ball flow path 26a can win at the normal winning part 34.

[0020] (Regarding the start winning parts 30 and 31) As shown in FIG. 2, on the gaming board 20, a first start winning section 30 where pachinko balls flowing down the gaming area 26 (the first ball flow-down path 26a and the second ball flow-down path 26b) can win is disposed at a position below the frame-shaped decoration 25 facing the gaming area 26. Also, a special winning section 32 is disposed on the right side of the first start winning section 30 facing the gaming area 26 (the second ball flow-down path 26b). Further, a gate section 33 through which pachinko balls flowing down the gaming area 26 (the second ball flow-down path 26b) can pass is disposed on the right side of the frame-shaped decoration 25 facing the gaming area 26 (the second ball flow-down path 26b). Furthermore, a second start winning section 31 is disposed below the gate section 33. The first and second start winning sections 30 and 31 are provided with start winning openings 30a and 31a where pachinko balls flowing down the gaming area 26 can win. Here, the first start winning section 30 is a constantly open type winning section where the first start winning opening 30a is constantly open to the gaming area 26, and the second start winning section 31 is an opening and closing type winning section where the second start winning opening 31a is opened and closed by a start opening and closing member (opening and closing means) 31b according to predetermined opening and closing conditions. Note that the second start winning section 31 includes a start winning solenoid (not shown) that opens and closes the start opening and closing member 31b, and the start winning solenoid is driven and controlled by a main control board (not shown) disposed on the back side of the pachinko machine 10.

[0021] The first and second start winning sections 30 and 31 are provided with a start winning detection sensor (not shown) as a winning detection means (detection means) for detecting pachinko balls that have won in the first and second start winning openings 30a and 31a. The start winning detection sensor is connected by wiring to the main control board. When a detection signal from the start winning detection sensor is input to the main control board, the main control board outputs a control signal to a payout control board (not shown) with the input of the detection signal from the start winning detection sensor as a payout condition for prize balls, so as to cause a ball payout device (not shown) to payout a preset number of prize balls. Also, the detection of pachinko balls by the first and second start winning detection sensors is used as a start condition for the game, and upon the establishment of this start condition, the main control board acquires various winning information (game information such as jackpot determination random numbers), and a special figure win lottery (win determination) is configured to be performed based on the acquired winning information. Then, the sub-control board (not shown) is configured to control the display device 17 so as to execute a symbol variation effect on the display device 17 based on the result of the special figure win lottery. That is, in the pachinko machine 10 of the embodiment, the start winning detection sensor is configured such that when it detects a pachinko ball, it is regarded as the establishment of a specific condition, and upon the establishment of this specific condition, the main control board performs a win determination.

[0022] Also, as a result of the symbol variation effect on the display device 17, when the symbols (ornamental figures) are fixedly stopped and displayed in a combination that results in a predetermined win display (predetermined specific display) on the display device 17 (for example, a specific display result such as three of the same ornamental figures), a win game (jackpot game) advantageous to the player is awarded. Along with the occurrence of the jackpot game, a jackpot game is conducted in which the special winning opening 32a of the special winning section 32 is opened under predetermined opening conditions, and the player is given an opportunity to obtain prize balls.

[0023] (Regarding the special winning section 32) The special winning section (winning section) 32 is provided with a special opening / closing member (opening / closing means) 32b that opens and closes a special winning opening (winning opening) 32a that opens into the game area 26 (second ball flow-down path 26b). It is configured such that the special opening / closing member 32b is displaced between a closed position where it closes and an open position where it opens in accordance with the drive of a special winning solenoid (not shown) as the drive means. Further, a special winning detector (not shown) as special detection means (detection means) for detecting a pachinko ball that has won in the special winning opening 32a is provided in the special winning section 32. The special winning detection sensor is connected to the main control board by wiring. When the special winning detection sensor detects a pachinko ball, it outputs a detection signal to the main control board, and the main control board outputs a control signal to the payout control board using the input of the detection signal from the special winning detection sensor as the payout condition for the prize balls, causing the ball payout device to payout a preset number of prize balls. The special winning solenoid is driven and controlled by the main control board after the end of the symbol variation effect by the display device 17 when a jackpot game that opens and closes the special winning opening 32a is given triggered by the winning of a pachinko ball in the first and second starting winning openings 30a and 31a. In the pachinko machine 10 of the embodiment, the second starting winning section 31 and the special winning section 32 are provided in a winning unit 35 detachably disposed on the game board 20.

[0024] (Regarding the gate section 33) A gate sensor (not shown) as detection means for detecting that a pachinko ball has passed through the gate section 33 is disposed in the gate section 33. The gate sensor is connected to the main control board by wiring. When a detection signal is input from the gate sensor to the main control board, that is, when the gate sensor detects a pachinko ball, various passing detection information (game information such as random numbers) is acquired, and a normal pattern win determination (normal pattern win lottery) is configured to be performed based on the acquired game information. Then, when a normal pattern win game that opens and closes the second starting winning opening 31a is given as a result of this normal pattern win lottery, the starting winning solenoid is driven and controlled so that the starting opening / closing member 31b performs an opening / closing operation.

[0025] (Regarding the general winning section 34) As shown in FIG. 2, the general winning section 34 is provided on the game board 20 at the lower left position (first ball flow-down path 26a) of the game area 26 so that a general winning opening 34a into which pachinko balls can win is always open upward. Pachinko balls flowing down the first ball flow-down path 26a can win the general winning opening 34a with a certain probability. The general winning section 34 is provided with a general winning detection sensor (not shown) as a winning detection means for detecting pachinko balls that have won the general winning opening 34a. The general winning detection sensor is wired and connected to the main control board. Then, with the detection signal from the general winning detection sensor being input to the main control board as a condition for paying out bonus balls, the main control board determines the payout of bonus balls and outputs a control signal to the payout control board to cause the ball payout device to pay out a preset number of bonus balls.

[0026] (Regarding the display device 17) A plurality of symbol sequences capable of variably displaying the decorative symbol as a performance symbol are set in the display device 17. When a winning occurs in the first start winning opening 30a or the second start winning opening 31a (when the start condition is satisfied), the decorative symbols of each symbol sequence start to vary. In the display device 17 of the embodiment, a plurality of effective stop positions (positions where the symbol is fixedly stopped and displayed, fixed stop display areas) where one decorative symbol can be stopped and displayed as a result of the symbol variation performance are set respectively. Through the symbol variation performance, a symbol combination (display result) of the decorative symbol fixedly stopped and displayed on the stop symbol effective line formed by combining the effective stop positions of each symbol sequence is derived. That is, in the display device 17, after variably displaying the decorative symbol (performance symbol) triggered by the satisfaction of the start condition, a predetermined decorative symbol (performance symbol) is fixedly stopped at the effective stop position. In the display device 17 of the embodiment, three symbol sequences are set in a horizontal side-by-side arrangement, and one effective stop position of the decorative symbol (performance symbol) is determined for each symbol sequence, and a symbol variation performance consisting of three decorative symbols (performance symbols) is performed. And it is possible to grasp that a big win game (winning game) is given when the decorative symbols of each symbol sequence fixedly stopped and displayed at the effective stop positions in the display device 17 are a winning symbol combination.

Note that the fourth to sixth guide game pins 23G to 23I are arranged in a substantially arc shape in which the side of the seventh guide game pin 23J is concave.

[0029] (Regarding the first regulating member 37) As shown in FIG. 3, at least the guiding game pins 23A to 23F, which are located in the second ball flow-down path 26b on the upstream side of the gate portion 33 that is a means affecting the game of the pachinko machine, are detachably disposed with a first regulating member 37 that covers them at a position spaced forward from the board surface of the game board 20. The first regulating member 37 is disposed between the left rail portion 21a of the guide rail 21 that defines the second ball flow-down path 26b between the eaves-shaped portion 25b of the frame-shaped decorative body 25, and extends substantially parallel to the board surface so as to define the second ball flow-down path 26b between the board surface and the board surface at a distance greater than the diameter of the pachinko ball from the board surface of the game board 20. The first regulating member 37 is configured such that at least the first front cover portion 38 is formed of a transparent material (transparent resin), and the movement of the pachinko ball flowing through the second ball flow-down path 26b is visible from the front side. As shown in FIG. 4, on the first front cover portion 38, at positions corresponding to the guiding game pins 23A to 23F, restricting portions 39 to 42 capable of accommodating the heads 23b of the guiding game pins 23A to 23F are formed in a concave shape that opens at least on the board surface side. In the embodiment, a first restricting portion 39 that opens on the board surface side and encloses the two guiding game pins 23A and 23C, which are the first guiding game pin 23A and the second guiding game pin 23C arranged vertically on the left side, a second restricting portion 40 that opens on the board surface side and encloses the two guiding game pins 23B and 23D, which are the first guiding game pin 23B and the second guiding game pin 23D arranged vertically on the right side, a third restricting portion 41 that opens on the board surface side and below (gate portion side) and encloses the one guiding game pin 23E on the left side, and a fourth restricting portion 42 that opens on the board surface side and below (gate portion side) and encloses the one guiding game pin 23F on the right side are formed on the first front cover portion 38.

[0030] The inner surfaces of the first to fourth regulating portions 39 to 42 formed on the first front cover portion 38 and located laterally spaced from the head 23b function as regulating surfaces (hereinafter referred to as index surfaces) 39a to 42a that regulate a displacement of the guide game pins 23A to 23F by a predetermined amount or more in a direction intersecting the extending direction of the guide game pins 23A to 23F. As shown in FIG. 4, each of the index surfaces 39a and 40a in the first regulating portion 39 and the second regulating portion 40 follows the outer shape of the head 23b of the corresponding guide game pins 23A, 23C, 23B, and 23D and is along the outer periphery of the head 23b, and includes a curved surface portion 43 in a semi-circular arc shape (curved surface) having a diameter larger than that of the head 23b, and linear portions 44, 44 extending linearly so as to connect both the curved surface portions 43, 43. The curved surface portion 43 and the linear portion 44 are spaced apart from the head 23b by a predetermined distance. In the first regulating portion 39 and the second regulating portion 40, the separation distance L between each of the linear portions 44 facing each other in the left-right direction (the width direction of the first ball passage 36A) with the corresponding guide game pins 23A, 23C or guide game pins 23B, 23D interposed therebetween and the head 23b is such that the pin intervals of the first guide game pins 23A, 23B and the second guide game pins 23C, 23D arranged in the left-right direction are adjusted to narrow the left-right dimension (passage dimension) of the first ball passage 36A so that the pachinko balls do not enter the passage port 33a of the gate portion 33 at all from the first ball passage 36A, or conversely, the pin intervals are extremely widened so that the pachinko balls enter the passage port 33a of the gate portion 33 excessively. The dimension is set to be regulatable. This makes it difficult to adjust the pin intervals of the guide game pins 23A to 23D to be excessively narrow, preventing the game performance initially set for the pachinko machine from being maintained, or preventing the pachinko balls from being illegally obtained by an act of widening the pin intervals excessively.

[0031] As shown in FIG. 4, each of the index surfaces 41a and 42a in the third regulating portion 41 and the fourth regulating portion 42 is formed along the outer periphery of the head 23b in accordance with the outer shape of the head 23b of each corresponding guide game pin 23E, 23F, and includes a curved surface portion 45 in the shape of a semi-circular arc (curved surface) having a diameter larger than that of the head 23b and straight portions 46, 46 extending linearly downward from both ends of the curved surface portion 45. Also in the third regulating portion 41 and the fourth regulating portion 42, similar to the first regulating portion 39 and the second regulating portion 40, the separation distance L between each straight portion 46 and the head 23b is such that the pin spacing of the third guide game pins 23E, 23F arranged in the left-right direction narrows the left-right dimension (passage dimension) of the second ball passage 36B, so that the pachinko ball does not enter the passage port 33a of the gate portion 33 at all from the second ball passage 36B, or conversely, the pin spacing is extremely widened so that the pachinko ball enters the passage port 33a of the gate portion 33 excessively, and is set to a dimension that can regulate this.

[0032] That is, in the first regulating member 37 of the embodiment, the index surfaces 39a to 42a facing the sides of the heads 23b of the guide game pins 23A to 23F are set so as to be able to regulate the pin spacing of the first guide game pins 23A, 23B, the second guide game pins 23C, 23D, and the third guide game pins 23E, 23F arranged in the left-right direction, narrow the left-right dimensions of the first and second ball passages 36A, 36B, and prevent the pachinko ball from entering the passage port 33a of the gate portion 33 at all from the ball passages 36A, 36B, or conversely, extremely widen the pin spacing so that the pachinko ball enters the passage port 33a of the gate portion 33 excessively.

[0033] As shown in FIG. 4, in each of the restricting portions 39 to 42 of the first restricting member 37, each of the reference surfaces 39a to 42a is such that the nail intervals and driving angles of the respective guiding game nails 23A to 23F are adjusted to positions (initial positions) capable of maintaining game performances such as a winning rate and a ball discharging rate preset in the pachinko machine (the state shipped from the manufacturer). In this state, the lateral separation distance L between the outer periphery of the head 23b and the reference surfaces 39a to 42a (specifically, the straight portions 44, 46) is set to be substantially equal, and the change in the separation distance between the guiding game nails (specifically, the heads 23b) 23A to 23F and the reference surfaces 39a to 42a is set to be distinguishable. That is, if the head 23b is displaced laterally from the middle of the reference surfaces 39a to 42a (the straight portions 44, 46) facing each other in the lateral direction, it can be recognized that the guiding game nails 23A to 23F have been adjusted or rigged from the initial position and displaced. Further, in each of the restricting portions 39 to 42, the separation distances between the curved surface portions 43, 45 facing the heads 23b of the corresponding guiding game nails 23A to 23F are also set to be equal throughout the circumferential direction at the initial positions of the guiding game nails 23A to 23F, and the displacement of the guiding game nails 23A to 23F in the facing direction with the curved surface portions 43, 45 from the initial positions can also be recognized.

[0034] (Regarding the rib 47) As shown in FIG. 6, the first front cover portion 38 is provided with a rib 47 protruding toward the game board surface of the game board 20. This rib 47 faces the second ball flowing-down path 26b so that the pachinko ball flowing down the second ball flowing-down path 26b can come into contact therewith. In the embodiment, the rib 47 is arranged to face the second ball flowing-down path 26b on the upstream side of the first ball passage 36A, and by this rib 47, the ratio of the pachinko ball flowing down the second ball flowing-down path 26b flowing through the first ball passage 36A and the second ball flowing-down path 26b other than the first ball passage 36A can be made different.

[0035] (Regarding the light-emitting means 48) As shown in FIG. 6, on the gaming board 20, at a position facing the first front cover portion 38 of the first regulating member 37, light emitting means 48 such as an LED capable of irradiating light toward the first front cover portion 38 (front side) is disposed. In FIG. 6, the light emitting means 48 provided at a position corresponding to the first regulating portion 39 is shown, but the light emitting means 48 is also disposed at portions corresponding to the other regulating portions 40 to 42, respectively. And, the light irradiated from the light emitting means 48 can decoratively illuminate the first front cover portion 38, and is configured such that the light irradiated from the light emitting means 48 can be reflected by the indicator surfaces 39a to 42a. Further, when light is reflected by the indicator surfaces 39a to 42a, the presence of each guiding gaming pin 23A to 23F located inside the first to fourth regulating portions 39 to 42 and the change in the distance between the indicator surfaces 39a to 42a and the heads 23b of the guiding gaming pins 23A to 23F can be sensuously recognized. That is, when the light reflected by the indicator surfaces 39a to 42a hits the head 23b, when the separation distance between the indicator surfaces 39a to 42a and the head 23b is long, the way of shining by the reflected light of the head 23b becomes weak, whereas when the separation distance between the indicator surfaces 39a to 42a and the head 23b is short, the way of shining by the reflected light of the head 23b becomes strong, and the displacement from the initial position of the head 23b can be recognized by the strength or weakness of the way of shining. Thus, the indicator surfaces 39a to 42a that regulate the displacement of the guiding gaming pins 23A to 23F have a function of indicating the presence and displacement of the gaming pins 23A to 23F.

[0036] (Regarding the second regulating member 49) As shown in FIG. 2, at least the guide game pins 23G to 23J, which are located in the second ball flow-down path 26b upstream of the second start winning part 31 that is a means affecting the game of the pachinko machine, are detachably disposed with a second regulating member 49 covering them at a position spaced forward from the board surface of the game board 20. Similar to the first regulating member 37, the second regulating member 49 includes a flat second front cover part 50 that extends substantially parallel to the board surface so as to define the second ball flow-down path 26b between the board surface and the board surface at a distance greater than the diameter of the pachinko ball from the board surface of the game board 20. The second regulating member 49 is configured such that at least the second front cover part 50 is formed of a transparent material (transparent resin), and the movement of the pachinko balls flowing through the second ball flow-down path 26b can be visually recognized from the front side. As shown in FIG. 5, on the second front cover part 50, restricting parts 51 and 52 capable of accommodating the heads 23b of the guide game pins 23G to 23J are formed in a concave shape opening toward the board surface at positions corresponding to the guide game pins 23G to 23J. In the embodiment, a fifth restricting part 51 that collectively surrounds the three guide game pins 23G to 23I disposed biased to the upper left side of the start winning opening 31a and a sixth restricting part 52 that individually surrounds the seventh guide game pin 23J disposed biased to the upper right side of the start winning opening 31a are formed on the second front cover part 50.

[0037] As shown in FIG. 5, the inner surfaces of the fifth regulating portion 51 and the sixth regulating portion 52 formed on the second front cover portion 50 and spaced apart laterally of the head portion 23b function as index surfaces 51a and 52a that regulate a displacement of a predetermined amount or more of the guide game pins 23G to 23J in a direction intersecting the extending direction of the corresponding guide game pins 23G to 23J, similarly to the first regulating portion 39 to the fourth regulating portion 42. As shown in FIG. 5, the index surface 51a of the fifth regulating portion 51 includes a curved surface portion 53 having a semi-circular arc shape (curved surface) conforming to the outer shape of the head portions 23b of the fourth and sixth guide game pins 23G and 23I, and arc-shaped portions 54 and 54 conforming to the arrangement of the three guide game pins 23G to 23F so as to connect both the curved surface portions 53 and 53. The curved surface portion 53 and the arc-shaped portions 54 are spaced apart from the head portion 23b by a predetermined distance. In the curved surface portion 53 of the fifth regulating portion 51, the separation distance L between the head portion 23b and the seventh guide game pin 23J in the approaching and separating direction (the direction of narrowing or widening the third ball passage 36C) of the fourth or sixth guide game pin 23G or 23I, and in the arc-shaped portion 54, the separation distance L between the head portion 23b and the seventh guide game pin 23J in the approaching and separating direction of the fifth guide game pin 23H are the same as those of the first regulating portion 39 to the fourth regulating portion 42. The pin intervals between the fourth to sixth guide game pins 23G to 23I defining the third ball passage 36C and the seventh guide game pin 23J are set to dimensions that can regulate making the passage dimension of the third ball passage 36C so narrow that no pachinko ball enters the start winning opening 31a of the second start winning portion 31, or conversely, making the pin intervals extremely wide so that an excessive number of pachinko balls enter the start winning opening 31a of the second start winning portion 31. Thereby, it becomes difficult to adjust the pin intervals of the guide game pins 23G to 23J to be excessively narrow, and it is possible to prevent the game performance initially set for the pachinko machine from being unable to be maintained, or prevent the pachinko balls from being illegally obtained by an act of widening the pin intervals excessively like a brute force.

[0038] As shown in FIG. 5, the reference surface 52a in the sixth restricting portion 52 is formed into a circular shape (curved surface) that conforms to the outer shape of the head 23b of the seventh guiding game pin 23J, and the separation distance L from the head 23b is equal throughout the entire circumferential direction of the head 23b (the head 23b is positioned at the center of the sixth restricting portion 52). Further, similar to the relationship between the reference surface 51a of the fifth restricting portion 51 and the guiding game pins 23G to 23I, the separation distance L between the head 23b and the reference surface 52a restricts the pin intervals between the fourth to sixth guiding game pins 23G to 23I and the seventh guiding game pin 23J by narrowing the passage dimension of the third ball passage 36C, such that the pinball does not enter the start winning opening 31a of the second start winning portion 31 at all from the third ball passage 36C, or conversely, by extremely widening the pin interval, such that the pinball enters the start winning opening 31a of the second start winning portion 31 excessively. The separation distance L is set to a dimension that can regulate this.

[0039] Also, in the second restricting member 49 as well, the relationship between the reference surface 51a of the fifth restricting portion 51 and the heads 23b of the fourth to sixth guiding game pins 23G to 23I, and the relationship between the reference surface 52a of the sixth restricting portion 52 and the head 23b of the seventh guiding game pin 23J are the same as in the case of the first restricting member 37. The separation distances (the distances in the direction of narrowing or widening the third ball passage 36C) from the heads 23b of the corresponding guiding game pins 23G to 23J to the opposing reference surfaces 51a and 52a are the same, and the displacements of the guiding game pins 23G to 23J from their initial positions with respect to the reference surfaces 51a and 52a can be recognized. The lengths of the reference surfaces 39a to 42a, 51a, and 52a in the front-rear direction in the first and second restricting members 37 and 49 are set to dimensions that can contact the heads 23b whose height positions change from the game board surface 20 when the guiding game pins 23A to 23J are bent to be displaced from their initial positions, and restrict further displacement of the heads 23b. Note that a rib (not shown) is provided on the second front cover portion 50 of the second restricting member 49, against which the pinball flowing down the second ball flow path 26b abuts and changes its flow direction. Also, at a position corresponding to the second front cover portion 50 on the game board 20, a light emitting means (not shown) that irradiates light toward the second front cover portion 50 is provided, and the light irradiated from the light emitting means is configured to be reflected by the corresponding reference surfaces 51a and 52a.

[0040] Here, the driving-in angles of the fourth to sixth guide game pins (first game pins) 23G to 23I with respect to the game board 20 are different. And, on the index surface 51a of the fifth regulating member 51 of the second regulating member 49 that collectively surrounds the three guide game pins 23G to 23I with different driving-in angles, the portion (curved surface portion 53) facing the heads 23b of the fourth and sixth guide game pins (first game pins) 23G and 23I and the portion (arc-shaped portion 54) facing the head 23b of the fifth guide game pin (second game pin) 23H are formed in shapes corresponding to differences such as the driving-in angles of the respective guide game pins 23G to 23I. That is, the index surface 51a of the fifth regulating member 51 is formed such that the shape of the index surface 51a (curved surface portion 53) corresponding to the first guide game pins 23G and 23I that regulate displacement and the shape of the index surface 51a (arc-shaped portion 54) corresponding to the second guide game pin 23J that regulates displacement are different.

[0041] The light-emitting means 48 disposed corresponding to the first and second regulating members 37 and 49 is configured to be capable of emitting light in a plurality of light-emitting modes with different light-emitting colors, and light of each color can be reflected by the index surfaces 39a to 42a, 51a, and 52a. Further, in the pachinko machine 10, during the symbol variation effect or the jackpot game, a plurality of types of light-emitting effects executable by the light-emitting means 48 are set with different light-emitting modes. And in the pachinko machine 10, based on the winning information acquired upon the establishment of the start condition by the detection of the pachinko balls by the first and second start winning detection sensors, the type of the light-emitting effect to be executed during the symbol variation effect or the jackpot game is determined and the light-emitting means 48 is configured to execute it. Each of the plurality of types of light-emitting effects is set such that the expected degree of being given a jackpot game is different depending on the combination of the probability of being selected in the case of a jackpot and the probability of being selected in the case of a miss in the special figure per draw (hit determination) based on the winning information. That is, it is configured such that the expected degree of being given a jackpot game after the symbol variation effect can be suggested by the type of the light-emitting effect executed during the symbol variation effect. Also, in the pachinko machine 10, as the types of jackpot games, a type in which an advantageous privilege state (probability variable state or shortening state) advantageous to the player is given after the end of the jackpot game and a type in which such a privilege state is not given are set, and each of the plurality of types of light-emitting effects is based on the probability of being selected when the type of the jackpot game determined by the special figure per draw based on the winning information is a jackpot game that gives a privilege state and the probability of being selected when the type of the jackpot game is a jackpot game that does not give a privilege state. The combination is set such that the expected degree of being given a privilege state after the end of the jackpot game is different. That is, it is configured such that the expected degree of being given a privilege state after the end of the jackpot game can be suggested by the type of the light-emitting effect executed during the jackpot game. Thus, in the pachinko machine 10, the type of the light-emitting effect executed by the light-emitting means 48 can suggest the expected degree of being given an advantageous state advantageous to the player, such as a jackpot game or a privilege state. Note that the types of light-emitting modes are not limited to differences in light-emitting colors, and those with different blinking intervals may also be used.

[0042] In the pachinko machine 10 of the embodiment, as fraud detection sensors for detecting fraud against the pachinko machine 10, a radio wave detection sensor for detecting radio waves, a magnetic detection sensor for detecting magnetism, etc. are arranged near means that affect games such as the gate part 33, the first start winning part 30, the second start winning part 31, the special winning part 32, and the normal winning part 34, which are targets of fraud. Further, the first and second regulating members 37 and 49 for regulating the displacement of the guide game pins 23A to 23J are configured to be located within the detection range of radio waves and magnetism by the fraud detection sensors.

[0043] 〔Operation of the embodiment〕 Next, the operation of the pachinko machine according to the above-described embodiment will be described.

[0044] In the pachinko machine 10 of the embodiment, since the displacement of the guide game pins 23A to 23J is regulated by the first regulating member 37 and the second regulating member 49, it is difficult to adjust the guide game pins 23A to 23J, and the expected game performance such as the winning rate and the ball launching rate preset in the pachinko machine 10 can be maintained. In particular, since the first regulating member 37 and the second regulating member 49 are arranged targeting the guide game pins 23A to 23J that guide pachinko balls to the gate part 33 and the second start winning part 31 that affect the game, the expected game performance can be maintained more suitably. Further, since the regulating members 37 and 49 are configured to be detachable from the game board 20, maintenance such as replacement of the regulating members 37 and 49 can be easily performed. Furthermore, it is possible to easily determine whether the guide game pins 23A to 23J are arranged at appropriate positions (initial positions) based on changes in the intervals between the index surfaces 39a to 42a, 51a, 52a of the regulating members 37 and 49 and the guide game pins 23A to 23J. Still further, in the index surfaces 39a to 42a, 51a of the regulating parts 39 to 42, 51 of the first and second regulating members 37 and 49, the straight parts 44 and 46 and the arc-shaped part 54 are connected by semi-circular arc-shaped curved surface parts 43, 45, and 53, so that it is possible to suppress the ends of the regulating parts 39 to 42, 51 from chipping or being damaged. Note that, in the regulating parts 41 and 42 of the first regulating member 37, the end opening downward may be formed in an R shape to suppress damage to the regulating member 37.

[0045] In the pachinko machine 10 of the embodiment, since the front cover portions 38 and 50 that cover the front sides of the guide game pins 23A to 23J in the first and second regulating members 37 and 49 are formed of a transparent material, the movement of the pachinko balls is not difficult to see due to the members that regulate the displacement of the guide game pins 23A to 23J, and there is no risk of giving the player a sense of distrust. Also, the decorativeness of the regulating members 37 and 49 can be enhanced by the light irradiated from the light emitting means 48 provided on the game board 20, and the interest can be improved. Further, the light irradiated from the light emitting means 48 is reflected by the respective index surfaces 39a to 42a, 51a, and 52a of the regulating members 37 and 49, so that the presence of the guide game pins 23A to 23J can be indicated and the displacement of the guide game pins 23A to 23J can be easily recognized. It becomes possible to recognize excessive pin adjustment by the game parlor or rough behavior by wrongdoers, and appropriate measures can be taken. Also, since ribs 47 that affect the flow-down direction (movement) of the pachinko balls are provided on the regulating members 37 and 49 that cannot be adjusted at the game parlor, it is possible to prevent the game performance from being modified by the game parlor. Further, since the regulating members 37 and 49 are detachable from the game board 20, they can be easily replaced when the ribs 47 that the pachinko balls contact wear or are damaged. Also, by exchanging the existing regulating members 37 and 49 with regulating members having different rib 47 arrangement positions, it is possible to change to any game performance without changing the implantation positions of the guide game pins.

[0046] In the pachinko machine 10 of the embodiment, the fifth regulating portion 51 in the second regulating member 49 corresponds to the fourth guide game pin 23G and the sixth guide game pin 23I surrounded by the index surface 51a of the fifth regulating portion 51, and regulates the displacement of the fourth guide game pin 23G and the sixth guide game pin 23J. The shapes of the curved surface portion 53 and the arcuate portion 54 corresponding to the fifth guide game pin 23H are formed into corresponding shapes according to the driving angles and arrangement positions of the guide game pins 23G, 23H, 23I with respect to the game board 20. Therefore, the displacements of the respective guide game pins 23G, 23H, 23I can be appropriately regulated. Further, the sixth regulating portion 52 in the second regulating member 49 is formed into a curved surface (circular shape) along the outer shape of the head 23b of the seventh guide game pin 23J surrounded by the index surface 52a of the sixth regulating portion 52. Therefore, the displacement of the seventh guide game pin 23J in the radial direction can be appropriately regulated according to the driving angle of the seventh guide game pin 23J with respect to the game board 20.

[0047] (Regarding another embodiment) FIG. 7 shows another embodiment of the regulating portion provided in the regulating member. In the regulating member 55 of the other embodiment, a regulating portion 58 having an index surface 58a surrounding the head 23b of the guide game pin 56 is provided on a transparent front cover portion 57 that covers the guide game pin 56 for guiding the pachinko ball to the gate portion 33 and the second starting winning portion 31 from the front side. The index surface 58a in the regulating portion 58 is formed in a polygonal shape as shown in the figure. The separation distance between each surface facing the head 23b and the head 23b in the polygonal index surface 58a is set to a dimension that can regulate a displacement of the guide game pin 56 by a predetermined amount or more in a direction intersecting the extending direction of the guide game pin 56, similar to the embodiment. In this way, by surrounding the head 23b with a plurality of surfaces, the displacement of the head 23b in the radial direction can be suitably regulated according to the driving angle of the guide game pin 56 with respect to the game board 20.

[0048] (Modification example) The present invention is not limited to the configurations of the embodiments or alternative embodiments. For example, it can be modified as follows. Also, the following modification examples can be adopted in combination with each other, and for the configurations described in the embodiments and the like, various embodiments can be adopted within the scope of the gist of the present invention. (1) In the embodiments and the like, as means for affecting the game, the gate part and the second start winning part were mentioned. However, as means for affecting the game, any of the first start winning part, the special winning part, the normal winning part, or the inlet of the frame-shaped decoration body may be used. (2) In the embodiments and the like, the restricting member was disposed on the frame-shaped decoration body or the winning unit. However, the object on which the restricting member is disposed can adopt a configuration in which it is disposed on the game board or various other decorative members and the like. (3) In the embodiments and the like, the separately configured restricting member was detachably disposed on the object to be disposed such as the frame-shaped decoration body or the winning unit. However, a configuration can be adopted in which it is detachably disposed on the game board and the restricting member is integrally provided on various components arranged around the guiding game nail. That is, various components disposed on the game board can be used as the restricting member, and the part facing the side of the guiding game nail in the component can be used as the index surface. (4) In the embodiments and the like, the inner surface of the restricting part provided on the restricting member was used as the index surface. However, the inner surface of the through hole penetrating in the front-rear direction provided on the restricting member can be used as the index surface. (5) The number and position of the ribs provided on the restricting member can be arbitrarily set according to the position and number of the guiding game nails that restrict displacement on the index surface of the restricting member. (6) In the embodiments and the like, the light emitting means was disposed on the game board. However, the light emitting means can be disposed on the decorative member disposed on the game board, the movable body, or the like. Also, various light emitting means for decorating the game board with light can be used as the light emitting means for irradiating light on the restricting member. (7) In the embodiment, it is formed such that the reference surface is perpendicular to the game board surface, but it may be inclined according to the driving-in angle of the guiding game pins with respect to the game board surface. Also, the reference surfaces on both sides sandwiching the guiding game pins may be inclined so as to expand toward the game board surface. By configuring in this way, the light from the light-emitting means provided on the game board can be effectively reflected. (8) The separation distance between the head of the guiding game pin and the reference surface does not necessarily need to be the same length on both sides sandwiching the guiding game pin, and may be different. The pin interval of the guiding game pins defining the ball passage path may be set to an interval at which the pachinko balls do not enter the passage opening of the gate portion or the start winning opening of the second start winning portion at all, or conversely, the pin interval may be extremely widened to an interval at which the pachinko balls enter the passage opening or the start winning opening excessively, as long as it is set to a dimension that can regulate this. (9) A configuration can be adopted in which a buffer member (a member other than the game pin) against which the pachinko ball before contacting the guiding game pin can abut is provided so as to face the game area upstream of the implantation position of the guiding game pin whose displacement is regulated by the regulating member. According to this configuration, since the pachinko ball whose speed has been reduced by the buffer member comes into contact with the guiding game pin, deformation of the guiding game pin and the like can be suppressed. Note that the buffer member can be provided continuously or separately with respect to the regulating member.
