  As shown in FIG. 2, a back mechanism board 200 is attached to the inner frame 14 of the pachinko machine 10 so as to cover the back side of the game board 26. The back mechanism panel 200 mainly supplies power to the payout control board case set 202 containing the payout control board 104, the launch control board case set 204 containing the launch control board 108, and the pachinko machine 10. A power supply circuit board case set 208 that accommodates the power supply circuit board 206 is attached thereto. Each of these board case sets 202, 204, and 208 is configured to protrude to the back side of the pachinko machine 10 through the outer frame 12 after being assembled.

  Next, the surface structure of the game board 26 will be described.

  As shown in FIG. 3, the game board 26 is held by the inner frame 14, and the back side of the game board 26 is covered by the back mechanism board 200. In the game board 26, a substantially circular game area 28 is formed by an outer rail 50 and an inner rail 52 provided on the surface of the game board 26. Inside the game area 28, a central device 54, a start port 56B, a warp entrance 58, and a number of obstacle nails 60 are disposed.

  The central device 54 is disposed substantially at the center of the game area 28 and includes an effect symbol display device 62, a center accessory 64, and a lamp device 66.

  The effect symbol display device 62 is display-controlled based on control signals from the main control board (game control board) 102 and the sub-control board 106, and has a substantially rectangular display surface (display area). On this display surface, special design effects are displayed. Specifically, on the display surface of the effect symbol display device 62, an effect symbol display area is formed in which one or more effect symbols are displayed while being changed one after another in a predetermined direction and then stopped. That is, the left effect symbol display area for displaying the left effect symbol, the center effect symbol display area for displaying the center effect symbol, and the right effect symbol display area for displaying the right effect symbol are arranged in a substantially horizontal row. They are formed side by side (not shown). In each effect symbol display area, a symbol variation direction is set in a direction (vertical direction) substantially orthogonal to the arrangement direction of these display areas, and a plurality of effect symbols are sequentially displayed in that direction.

  The effect symbol display device 62 causes the effect symbols displayed in the display area of the display surface to change and stop display when the game ball enters the start opening 56B. Then, for example, when the production symbols are aligned with the same three-digit symbols “7, 7, 7” and stopped (determined display), the big winning opening 86 of the big winning device 84 arranged in the variable winning device 80 is opened. Is done. In the pachinko machine 10 of the present embodiment, when a game ball enters the start opening 56B, each effect symbol is changed, and the effect symbol is arranged in the same three-digit symbol, thereby giving a specific value of “big hit”. is there.

  Here, in the pachinko machine 10 of the present embodiment, for example, two types of big hits are set in advance. Specifically, there is a probable big hit that is established when three digits of the same odd-numbered effect symbols such as “7, 7, 7” are arranged. In addition, there is a normal jackpot that is established when the same even-numbered effects such as “8, 8, 8” are arranged in three digits.

  The probable big hit and the normal big hit are big hits having a relatively large number of rounds (for example, 15 rounds) and the opening time of the big winning opening 86 being about 26 seconds. For this reason, the number of prize balls is relatively large. In each big hit, a predetermined number (for example, 10) of game balls enter the big winning opening 86, or a predetermined time (for example, 10) even if a predetermined number (for example, 10) of the game balls do not enter. For example, when 26 seconds) elapses, the big winning opening 86 is closed and one round is completed.

  Further, the probability variation state is a state in which the probability of shifting to a big hit (meaning two kinds of big hits, a probable big hit and a normal big hit) becomes a predetermined high probability. The open time extended state is a state in which the opening time of the start port 56B is extended more than usual. For example, the normal opening time is about 0.1 seconds, while in the extended opening time state, it is extended to about 4 seconds. The start port 56B is opened by winning a normal symbol lottery, and functions as a normal electric accessory.

  In addition, after the probable big hit, the probability of shifting to the big hit becomes a special symbol probability fluctuation state in which the probability is higher than the normal gaming state. Then, the variation time of the special symbol and the normal symbol is shortened until the next big hit is generated, or until the special symbol variation display is performed a predetermined number of times (for example, 10,000 times), and the start port 56B. The open extension function is activated. In addition, after the normal jackpot, the probability of shifting to the big jackpot becomes a predetermined low probability state that is the same as the normal gaming state, and the variation time of the special symbol and the normal symbol is reduced by a predetermined number of times (for example, 100 times). When the opening extension function of the start port 56B is activated, the short game state is set.

  The center accessory 64 is mounted so as to protrude from the front peripheral portion of the effect symbol display device 62. The center accessory 64 has a pair of movable blade pieces 64A. The opening area of the warp entrance 58 is changed by the movement of the blade piece 64A.

  In addition, on the lower left side of the game area, a 7-segment display board (design) which controls display of an identification symbol (which means an identification symbol of a special symbol and an identification symbol of a normal symbol) based on a control signal from the main control board 102. Display device) 68 is arranged. The 7-segment display board 68 displays a 7-segment display 70 for displaying a special symbol identification symbol, four normal symbol hold display LEDs 72, four special symbol hold indication LEDs 74, and a normal symbol identification symbol. And two normal symbol display LEDs 76.

  Here, in the case of a probable big hit, a predetermined identification symbol (for example, a probable big hit symbol consisting of an odd number) is stopped and displayed on the 7-segment display 70. In the case of a normal big hit, another predetermined identification symbol (for example, a normal big hit symbol consisting of an even number) is stopped and displayed on the 7-segment display 70.

  Further, a normal symbol operation gate 78 is arranged on the left side of the effect symbol display device 62. A gate switch 124 (see FIG. 5) is disposed inside the normal symbol operating gate 78. As a result, when the game ball passes the normal symbol operation gate 78, the gate switch 124 is operated, and the normal symbol display LED 76 of the 7-segment display board 68 is variably displayed.

  Each normal symbol hold display LED 72 and each special symbol hold display LED 74 are composed of four round red LEDs, and are arranged close to the left and right sides of the 7-segment display 70. In this case, the number of game balls that have passed through the normal symbol operation gate 78 is set to hold the normal symbols up to four, and the lights are sequentially turned on and shifted for each passage. In addition, the number of game balls that have entered the start opening 56B is also reserved for up to four special symbols, which are sequentially lit and shifted for each incoming ball. Each time the variable display on the 7-segment display 70 starts, the number of unstarted times is exhausted, and one special symbol hold display LED 74 is turned off. Further, each time the normal symbol display LED 76 starts to change the normal symbol, the number of unstarted times is consumed, and one normal symbol hold display LED 72 is turned off. Then, when a predetermined jackpot symbol is stopped and displayed on the 7-segment display 70, a jackpot is generated and the jackpot 86 is opened. Further, when the two normal symbol display LEDs 76 are stopped and displayed in a predetermined display mode (a winning symbol), a normal symbol hit occurs and the start port 56B is opened. The special symbol identification symbol displayed on the 7-segment display 70 and the special symbol effect symbol displayed on the effect symbol display device 62 indicate the same game result (lottery result). .

  The start port 56B is disposed below the effect symbol display device 62 and is formed so as to open and close the pair of wing piece members 56A in a so-called tulip type. Inside thereof, there are provided a start port switch 120 (see FIG. 5) for detecting the passage of the game ball and a start port solenoid 130 (see FIG. 5) for operating the wing piece member 56A. When the pair of wing piece members 56A are opened to the left and right, the opening area of the start port 56B is increased, and the possibility of entering a game ball is increased. When the pair of wing piece members 56A are closed and the separation distance is reduced. The opening area of the start opening 56B is reduced, and the normal state is reduced where the possibility of entering a game ball is reduced.

  The variable winning device 80 is disposed below the start opening 56 </ b> B, and includes a substrate 82 and a big winning device 84. Here, the grand prize winning device 84 is disposed substantially at the center, and has a grand prize winning opening 86 opened in a strip shape, an opening / closing plate 88 for opening or closing the special winning prize opening 86, and opening / closing the opening / closing plate 88. A large winning opening solenoid 132 (see FIG. 5) and a count switch 126 (see FIG. 5) for detecting a winning ball.

  A windmill 63 is disposed on the lower left side of the central device 54. Further, a pair of side lamps 90 are respectively disposed on the lower left portion and the lower right portion of the game area.

  Further, an out port 92 is provided below the game board 26, and a back ball preventing member 94 is provided below the out port 92. The back ball preventing member 94 prevents the game ball that has returned without reaching the game area 28 from returning to the launch position again. A foul ball prevention member 96 is attached to the tip of the inner rail 52.

On the outer surface on one side of the substrate case 214, a first flange portion (first flange member) 220 made of a colorless and transparent resin is integrally formed. The first flange 220 is formed with a first insertion hole (first hole) 222 into which the pin member 218 is inserted so as to extend in the thickness direction of the first flange 220 (substrate case 214). The diameter (diameter) of the first insertion hole 222 is set slightly smaller than the diameter (diameter) of a press-fit shaft member (shaft member) 240 that will be described later that constitutes the pin member 218.

  A first engaging portion made of colorless and transparent resin is formed on the side surface of the substrate case 214 opposite to the first flange portion 220. As shown in FIGS. 16 to 18, the first engagement portion supports the side wall portion 280 of the substrate case 214 and the slide prevention member (engagement member) 250 and supports the side wall portion 280 of the substrate case 214 to the substrate case 214. A supporting piece (supporting portion) 282 extending in the sliding direction, a fitting hole 284 formed at a position facing the supporting piece 282 of the substrate case 214 and penetrating the substrate case 214 in the thickness direction, and one inner side surface 284A of the fitting hole 284 And a first positioning end (first positioning portion) 286 that contacts the one end surface 254 of the slide prevention member 250 supported by the support piece 282 and positions the slide prevention member 250.

  One end of the support piece 282 is connected to the side wall 280 of the substrate case 214 to be a fixed end, and the other end is a free end. When the slide preventing member 250 is placed on the support piece 282, the slide preventing member 250 is supported by the support piece 282.

  The size of the insertion hole 284 is set to be substantially the same as or slightly larger than the size of the flat-plate-shaped slide prevention member main body 252 of the slide prevention member 250. For this reason, as shown in FIG. 19, in a state where the slide prevention member 250 is inserted from the insertion hole 284 and supported by the support piece 282, the four outer surfaces 254, 258, 262 of the slide prevention member main body 252 are inserted. The four inner side surfaces 284A, 284B, 284C, and 284D of the hole 284 are configured to be in contact with each other. As a result, it becomes impossible for the slide preventing member 250 to move inside the insertion hole 284.

  The first positioning end 286 contacts one outer surface 254 of the anti-sliding member main body 252 in a state where the anti-sliding member 250 is fitted to the support piece 282, and one side in the sliding direction of the substrate case 214 of the anti-sliding member 250. The anti-sliding member 250 is positioned by preventing the movement to the position.

  As shown in FIGS. 7 to 10, the case cover 216 is a resin-made colorless and transparent cover that is joined to the substrate case 214 and covers the main control substrate 102 with the substrate case 214. On the outer surface on one side of the case cover 216, a colorless and transparent resin-made second flange portion (second flange member) 224 is integrally formed. A second insertion hole 226 into which the pin member 218 is inserted is formed in the second flange portion 224 so as to penetrate in the thickness direction of the second flange portion 224 (case cover 216). The second insertion hole 226 includes an enlarged hole portion 226A having a relatively large inner diameter, and a reduced diameter hole portion communicating with the enlarged hole portion 226A and having a diameter smaller than the diameter (diameter) of the enlarged hole portion 226A. 226B. The diameter (diameter) of the enlarged hole portion 226A is set to be larger than the diameter (diameter) of the press-fit shaft member 240 constituting the pin member 218, and is the maximum diameter (diameter) of the head member 242 of the pin member 218. The diameter is set to be approximately the same. The diameter (diameter) of the reduced diameter hole 226B is set to be substantially the same as or slightly smaller than the diameter (diameter) of the press-fit shaft member 240. As shown in FIG. 10, when the pin member 218 is inserted into the opening 228 of the second insertion hole 226, the head member 242 engages with the stepped portion 230 between the enlarged diameter hole portion 226A and the reduced diameter hole portion 226B. Therefore, further movement of the pin member 218 in the depth direction of the second insertion hole 226 (thickness direction of the second flange portion 224) (further movement toward the second flange portion 224) is prevented, and the pin member 218 is Positioning is performed inside the first insertion hole 222 and the second insertion hole 226.

  A second engaging portion made of colorless and transparent resin is formed on the side surface of the case cover 216 opposite to the second flange portion 224. As shown in FIGS. 16 to 18, the second engaging portion is formed on the side wall portion (second positioning portion) 290 of the case cover 216 and the side wall portion 290 of the case cover 216 along the sliding direction of the case cover 216. And a guide hole 292 penetrating therethrough.

  The side wall portion 290 of the case cover 216 contacts the second claw portion 260 and the third claw portion 264 of the slide prevention member 250 in a state where the slide prevention member 250 is placed on the support piece 282, and the insertion hole 284 of the board case 214 is inserted. The slide prevention member 250 is sandwiched between the first positioning end portion 286 and the slide prevention member 250 is positioned, and functions as a second positioning end portion. That is, the slide prevention member 250 is placed between the first positioning end portion 286 constituting one inner side surface 284A of the insertion hole 284 and the second positioning end portion constituting the side wall portion 290 of the case cover 216. The cover 216 is sandwiched from both sides in the sliding direction to prevent the substrate case 214 or the case cover 216 from sliding on the other side. As a result, the substrate case 214 and the case cover 216 cannot be separated from each other, and the main control substrate 102 accommodated therein cannot be taken out.

  The guide hole 292 is formed so that its shape is the same as the cross-sectional shape of the support piece 282 of the substrate case 214 (cross-sectional shape cut in a direction perpendicular to the sliding direction).

  As shown in FIGS. 9 and 16, in a state where the substrate case 214 and the case cover 216 are aligned (a state before sliding and joining), the side wall portion 290 of the case cover 216 is supported by the support piece 282 of the substrate case 214. It enters the part opposite to the free end. 10 and 17, when one of the substrate case 214 or the case cover 216 slides with respect to the other, the support piece 282 is free in the guide hole 292 formed in the side wall portion 290 of the case cover 216. As shown in FIG. 18, the side wall portion 290 of the case cover 216 and the side wall portion 280 of the substrate case 214 come into contact with each other as shown in FIG. When the side wall portion 290 of the case cover 216 and the side wall portion 280 of the substrate case 214 are in contact with each other, further sliding with respect to the other of the substrate case 214 or the case cover 216 is prevented, and the first flange portion of the substrate case 214 is prevented. 220 and the second flange portion 224 of the case cover 216 are in contact with each other, and the first insertion hole 222 and the second insertion hole 226 communicate with each other. Accordingly, the pin member 218 can be inserted from the opening 228 side of the second insertion hole 226, and the slide prevention member 250 can be inserted into the insertion hole 284 formed in the substrate case 214. .

  Here, a method of joining the substrate case 214 and the case cover 216 will be described.

  As shown in FIGS. 8 and 9, the substrate case 214 and the case cover 216 are opposed to each other to bring them closer together. In a state in which the substrate case 214 and the case cover 216 are in close contact with each other, the first flange portion 220 of the substrate case 214 and the second flange portion 224 of the case cover 216 are not in contact with each other and are in a state of being displaced from each other. ing. Then, as shown in FIG. 10, one of the substrate case 214 and the case cover 216 is slid with respect to the other so that the first flange portion 220 of the substrate case 214 and the second flange portion 224 of the case cover 216 are in contact with each other. Move. Accordingly, the first flange portion 220 of the substrate case 214 and the second flange portion 224 of the case cover 216 are in contact with each other, and the first insertion hole 222 and the second insertion hole 226 are in communication with each other. When the first insertion hole 222 and the second insertion hole 226 communicate with each other, the pin member 218 is inserted (press-fitted) from the opening 228 side of the first insertion hole 222 and the second insertion hole 226.

  Next, the configuration of the pin member 218 that maintains the joined state of the substrate case 214 and the case cover 216 so that they cannot be separated will be described.

  As shown in FIG. 10, the pin member 218 is made of metal as a whole, and a press-fit shaft member 240 that extends in a predetermined direction, and a head member that is integrally formed at one end portion in the axial direction of the press-fit shaft member 240. 242.

  The press-fitting shaft member 240 is made of metal and is formed in a cylindrical shape, and is press-fitted into the first insertion hole 222 and the second insertion hole 226.

  The head member 242 is made of metal and is formed so as to increase in diameter in a direction away from the connection site with the press-fit shaft member 240. For this reason, the diameter of the head member 242 gradually increases in the direction away from the press-fit shaft member 240.

  Next, the structure of the anti-sliding member that prevents the substrate case 214 or the case cover 216 from sliding relative to the other and prevents the substrate case 214 and the case cover 216 from being released from being joined will be described in detail.

  As shown in FIGS. 11 to 15, the slide prevention member 250 is made of a colorless and transparent resin as a whole, like the substrate case 214 and the case cover 216, and includes a flat plate-like slide prevention member main body 252, A first claw portion (claw portion) 256 formed in the vicinity of the outer surface 254 on one side in the sliding direction of the slide prevention member main body 252 and hanging in a direction perpendicular to the plane portion of the slide prevention member main body 252; A second claw portion (claw portion) 260 formed in the vicinity of the right outer surface 258 of 252 and hanging in a direction orthogonal to the plane portion of the anti-slide member main body 252, and an outer left surface 262 of the anti-slide member main body 252 And a third claw portion (claw portion) 264 that is formed in the vicinity and hangs in a direction orthogonal to the flat surface portion of the anti-slide member main body 252.

  The anti-slide member main body 252 is formed in a rectangular shape in plan view, and a through hole 266 is formed in the center. As shown in FIG. 19, when the slide prevention member 250 is inserted into the insertion hole 284 and supported by the support piece 282, the four outer surfaces 254, 258, 262, 268 of the slide prevention member main body 252 face each other. It is in contact with the four inner side surfaces 284A, 284B, 284C, 284D of the fitting hole 284 to be inserted.

  As shown in FIGS. 11 to 15, the first claw portion 256 has an inner surface on one side in the sliding direction of the insertion hole 284 when the slide preventing member 250 is inserted into the insertion hole 284 and supported by the support piece 282. It is a nail | claw part located in the vicinity of 284A. The first claw portion 256 is formed with a protrusion 256A that protrudes to one side in the sliding direction. When the slide prevention member 250 is inserted into the insertion hole 284 and supported by the support piece 282, if the slide prevention member 250 is forcibly removed from the insertion hole 284, the protrusion 256A of the first claw portion 256 is inserted into the insertion hole 284. The sliding prevention member 250 cannot be taken out from the insertion hole 284 by being caught on or near the inner side surface 284A on one side in the sliding direction. Further, the first claw portion 256 is set to have such a strength as to be damaged when the anti-sliding member 250 is forcibly removed from the insertion hole 284 with a greater force. For this reason, even if the first claw portion 256 is caught on the inner surface 284A on one side in the sliding direction of the insertion hole 284, if the slide prevention member 250 is forcibly taken out with a larger force, the first claw portion 256 is removed. Will be damaged, leaving traces of fraud. Note that a thin stress concentration portion may be formed in the first claw portion 256, and the stress concentration portion may be easily damaged.

  The second claw portion 260 is a claw portion located in the vicinity of the right inner surface 284B extending in the sliding direction of the insertion hole 284 when the slide preventing member 250 is inserted into the insertion hole 284 and supported by the support piece 282. is there. The second claw portion 260 is formed with a protrusion 260A that protrudes in a direction orthogonal to the sliding direction and a thin stress concentration portion 260B. When the slide prevention member 250 is inserted into the insertion hole 284 and supported by the support piece 282, when the slide prevention member 250 is forcibly removed from the insertion hole 284, the protrusion 260A of the second claw portion 260 is inserted into the insertion hole 284. The right side inner surface 284B is caught in or near the inner surface 284B, and the slide prevention member 250 cannot be removed from the insertion hole 284. Further, the stress concentration portion 260B of the second claw portion 260 is set to such a strength as to be damaged when the slide preventing member 250 is forcibly removed from the insertion hole 284 with a greater force. For this reason, even if the second claw portion 260 is caught by the inner side surface 284B on the right side of the insertion hole 284, if the slide prevention member 250 is forcibly taken out with a larger force, the stress concentration of the second claw portion 260 is caused. The portion 260B is damaged, and a trace of fraudulent activity remains.

  The third claw portion 264 is a claw portion located in the vicinity of the left inner surface 284C extending in the sliding direction of the insertion hole 284 when the slide preventing member 250 is inserted into the insertion hole 284 and supported by the support piece 282. is there. The third claw portion 264 is formed with a protrusion 264A protruding in a direction orthogonal to the sliding direction and a thin stress concentration portion 264B. When the slide prevention member 250 is inserted into the insertion hole 284 and supported by the support piece 282, if the slide prevention member 250 is forcibly removed from the insertion hole 284, the protrusion 264A of the third claw portion 264 is inserted into the insertion hole 284. The left side inner surface 284C of the slide member is caught in or near the inner surface 284C, and the slide prevention member 250 cannot be removed from the insertion hole 284. Further, the stress concentrating portion 264B of the third claw portion 264 is set to such a strength as to be damaged when the slide preventing member 250 is forcibly removed from the insertion hole 284 with a greater force. For this reason, even if the third claw portion 264 is caught on the inner side surface 284C on the left side of the insertion hole 284, if the slide prevention member 250 is forcibly taken out with a larger force, the stress concentration of the third claw portion 264 is caused. The part 264B is damaged, and a trace of fraud remains.

  Here, as shown in FIG. 18, in a state where the slide prevention member 250 is inserted into the insertion hole 284 and supported by the support piece 282, the side wall portion 280 of the substrate case 214 and the second claw portion 260 of the slide prevention member 250 are provided. And the side wall part 290 of the case cover 216 is in a space formed between the third claw part 264 and the third claw part 264. That is, in a state where the slide prevention member 250 is inserted into the insertion hole 284 and supported by the support piece 282, the side wall portion 290 of the case cover 216 is connected to the side wall portion 280 of the board case 214 and the second claw portion of the slide prevention member 250. 260 and the third claw portion 264 are sandwiched from both sides in the sliding direction.

  Next, the attachment method with respect to the 1st flange part 220 and the 2nd flange part 224 of the pin member 218 is demonstrated.

  8 to 10, the first flange portion 220 of the substrate case 214 and the second flange portion 224 of the case cover 216 are brought into surface contact with each other, and the first insertion hole 222 and the second insertion hole 226 are communicated with each other. . Thus, the first insertion hole 222 and the reduced diameter hole portion 226B of the second insertion hole 226 are connected to form one communication hole.

  Next, the press-fit shaft member 240 of the pin member 218 is inserted from the opening 228 (see FIG. 10) of the second insertion hole 226. As the pin member 218 is inserted, the press-fit shaft member 240 reaches the reduced diameter hole portion 226B of the second insertion hole 226 and is press-fitted into the reduced diameter hole portion 226B.

  When the pin member 218 is subsequently inserted, the press-fit shaft member 240 of the pin member 218 reaches the first insertion hole 222 of the first flange portion 220 and the opening 236 of the first insertion hole 222 (see FIG. 8). It is press-fitted inside.

  Next, a method for attaching the slide prevention member 250 from the insertion hole 284 will be described.

  As shown in FIGS. 9 and 16, the substrate case 214 and the case cover 216 are combined (the first insertion hole 222 and the second insertion hole 226 are not in communication with each other before being slid). Thus, the side wall portion 290 of the case cover 216 is inserted at a position facing the free end of the support piece 282 of the substrate case 214. At this time, the guide hole 292 formed in the side wall portion 290 of the case cover 216 is disposed in the vicinity of the free end of the support piece 282.

  Next, as shown in FIGS. 10 and 17, when one of the substrate case 214 or the case cover 216 is slid with respect to the other and the first insertion hole 222 and the second insertion hole 226 are made to communicate with each other, The piece 282 is inserted into the guide hole 292, and the distance between the side wall portion 280 of the substrate case 214 and the side wall portion 290 of the case cover 216 is reduced. When the sliding of one of the substrate case 214 and the case cover 216 is completely completed, the side wall portion 280 of the substrate case 214 and the side wall portion 290 of the case cover 216 come into contact with each other.

  In this state, as shown in FIG. 18, the slide prevention member 250 is inserted into the insertion hole 284 of the substrate case 214, and the first claw portion 256 of the slide prevention member 250 is placed on the support piece 282. Thereby, the slide preventing member 250 is supported by the support piece 282. Thus, the pin member 218 is inserted into the second insertion hole 226 from the case cover 216 side. On the other hand, the slide preventing member 250 is inserted into the insertion hole 284 from the substrate case 214 side. That is, the pin member 218 and the slide preventing member 250 are inserted from opposite directions.

  Here, in a state where the slide prevention member 250 is supported by the support piece 282, a space formed between the side wall part 280 of the substrate case 214 and the second claw part 260 and the third claw part 264 of the slide prevention member 250. In addition, the side wall 290 of the case cover 216 is positioned, and the side wall 290 of the case cover 216 and the side wall 280 of the substrate case 214 are in contact with each other. A slight gap is formed between the portion 260 and the third claw portion 264.

  At the same time, as shown in FIG. 19, the first claw portion 256 of the slide preventing member 250 is located on the inner side surface 284 </ b> A side on the one side in the sliding direction of the insertion hole 284. The second claw portion 260 is located on the inner side 284B side on the right side in the sliding direction of the insertion hole 284, and the third claw portion 264 is located on the inner side surface 284C side on the left side in the sliding direction of the insertion hole 284. Become.

  Thus, as shown in FIG. 18, in a state where the slide preventing member 250 is inserted into the insertion hole 284 and supported by the support piece 282, one of the substrate case 214 and the case cover 216 is slid to the other to form the substrate case. 214 and the case cover 216 are separated from each other, the side wall portion 290 of the case cover 216 comes into contact with the second claw portion 260 and the third claw portion 264 of the anti-slide member 250, and the second side wall portion 290 of the case cover 216 A predetermined pressing force acts on the second claw portion 260 and the third claw portion 264.

  When a predetermined pressing force is applied from the side wall portion 290 of the case cover 216 to the second claw portion 260 and the third claw portion 264 of the slide prevention member 250, the pressing force is applied to the second claw portion 260 and the third claw portion 264. Is transmitted to the slide prevention member main body 252 via. When the pressing force is transmitted to the anti-sliding member main body 252, the anti-sliding member 250 attempts to move in the direction in which the pressing force is applied, but the outer surface 254 on one side of the sliding direction of the anti-sliding member main body 252 is the inner surface of the insertion hole 284 Since it is positioned in contact with 286, the slide preventing member 250 does not move. As a result, the slide preventing member 250 interferes (obstructs) and the sliding of one of the substrate case 214 and the case cover 216 with respect to the other is prevented.

  Here, if a large force is applied to the substrate case 214 or the case cover 216 and one of them is slid with respect to the other, a large pressing force is applied to the second claw portion 260 and the third claw portion 264 of the slide preventing member 250. Works. As a result, as shown in FIGS. 12 and 13, the stress concentration portion 260 </ b> B of the second claw portion 260 and the stress concentration portion 264 </ b> B of the third claw portion 264, which are set to low strength, are damaged, and fraud Can be easily discovered.

  Further, as shown in FIG. 19, when the slide preventing member 250 is to be taken out from the insertion hole 284, the first claw portion 256 is caught on the inner side surface 286 on one side in the sliding direction of the insertion hole 284 or in the vicinity thereof. The claw portion 260 is caught on the right inner surface 284 of the insertion hole 284 or in the vicinity thereof, and the third claw portion 264 is caught on the left inner surface 284C of the insertion hole 284 or in the vicinity thereof. Thereby, it is possible to prevent the slide prevention member 250 from being taken out. When the slide prevention member 250 is forcibly taken out with a greater force, all or one of the first claw portion 256, the second claw portion 260, and the third claw portion 264 (especially, the stress concentration portions 260B and 264B) fall into disrepair. As a result, it is possible to easily find an illegal act to take out the anti-slide member 250.

  Further, similar to the slide prevention member 250, the substrate case 214, and the case cover 216, the slide prevention member 250 is made of a colorless and transparent resin. Therefore, when the slide prevention member 250 is supported by the support piece 282, the slide prevention member 250 is a substrate. Assimilating with the case 214 and the case cover 216 makes it difficult to find the anti-slide member 250 from the outside. As a result, fraudulent acts on the slide prevention member 250 can be prevented in advance.

  As described above, as shown in FIG. 7, according to the first embodiment, the joining state of the substrate case 214 and the case cover 216 is maintained by two different members, that is, the pin member 218 and the slide prevention member 250. Therefore, even if the pin member 218 is removed, the board case 214 and the case cover 216 cannot be separated (opened) to take out the main control board 102 inside. Thereby, the unauthorized action of the main control board 102 can be prevented with the two locking members.

  Further, since the method for removing the pin member 218 and the method for removing the slide prevention member 250 are different, the slide prevention member 250 cannot be removed with the same tool (means) as when the pin member 218 is removed. It is possible to improve the fraud prevention function.

  Further, when the pin member 218 faces the player (game board 26) side with the main control board case set 210 attached to the back surface of the game board 26, the anti-slide member 250 is connected to the player side. It is exposed to the other side. For this reason, it becomes impossible to access the slide prevention member 250 from the player side, and the slide prevention member 250 cannot be taken out. On the other hand, in the state where the main control board case set 210 is attached to the back surface of the game board 26, when the slide prevention member 250 faces the player (game board 26) side, the pin member 218 is connected to the player side. It is exposed to the other side. For this reason, it becomes impossible to access the pin member 218 from the player side, and the pin member 218 cannot be taken out. In this way, the pin member 218 and the anti-slide member 250 are exposed in opposite directions, and one of them is always facing the opposite side to the player side, so that it becomes impossible to take out the two members. As a result, it becomes impossible to take out the main control board 102 accommodated in the inside, and illegal acts can be prevented.

  In addition, when the pin member 218, the slide prevention member 250, the board case 214 or the case cover 216 is damaged (destructed) and the internal main control board 102 is taken out and an illegal act is performed, it is a matter of course. Therefore, the fact of fraud can be easily discovered.

  In each of the above embodiments, the first engagement portion is provided in the substrate case 214 and the second engagement portion is provided in the case cover 216. For example, the second engagement is provided in the substrate case 214. The case cover 216 may be provided with a first engagement portion. In this configuration, the slide prevention member 250 is inserted into a fitting hole formed in the case cover 216 (insertion from the case cover 216 side). At this time, the first insertion hole of the first flange portion 220 of the substrate case 214 is made a through hole, and the pin member 218 is inserted (press-fitted) from the opening of the first insertion hole of the substrate case 214. Is preferable (insertion from the substrate case 214 side).

  In each of the above embodiments, the present invention has been described by taking as an example a configuration in which the present invention is applied to the main control board case set 210 that accommodates the main control board 102. However, the present invention is not limited to this configuration. The present invention can also be easily applied to cases that accommodate boards related to other games, such as the case set 212, the payout control board case set 202, the launch control board case set 204, and the power board case set 208.
