<Configuration of main controller>
Next, the configuration of main controller 200 according to the present embodiment will be described with reference to FIG. 2 and FIGS. 5 to 9. In the following description, the directions indicated by the arrows in FIG. 5 will be described as the up-down direction, the front-back direction, and the left-right direction, respectively.

The main controller 200 includes a main control board 210 and a board case 220 that houses and holds the main control board 210. The main control board 210 is a CPU that performs various arithmetic processes related to games, a ROM that is a read-only storage device that stores control programs and the like, a RAM that is a storage device that can write and read information, and a plurality of It is configured to have an electrical connector and a printed board on which these are mounted. The main control board 210 is configured to control the progress of the game in the pachinko gaming machine PM by operating each drive circuit and the like according to the control program stored in the ROM.

The substrate case 220 includes a bottom case 221 having a substantially rectangular flat plate shape, and a top case 231 having a substantially rectangular container shape that opens forward, and is mainly formed inside the case formed by combining the bottom case 221 and the top case 231. The control board 210 can be housed. In the board case 220, the bottom case 221 and the top case 231 are coupled to each other by sliding the top case 231 in the left-right direction with respect to the bottom case 221, similarly to the conventionally known board case. The case caulking member 225 attached to the board case 220 is engaged with the bottom case 221 and the top case 231, thereby restricting the sliding movement of the top case 231 with respect to the bottom case 221 in the removal direction, and The substrate case 220 cannot be opened unless a part is broken and the case caulking member 225 is taken out. The bottom case 221 and the top case 231 are formed of a transparent resin material, and the main control board 210 housed inside the case is visible from the outside. A case side caulking insertion portion 226 into which the main body caulking member 270 is inserted is formed on the rear surface side of the substrate case 220 (see FIG. 7 ).

As shown in FIG. 5, the board case 220 accommodating and holding the main control board 210 is attached to the lower part of the back set board 30 (frame member) via a case bracket 250. As shown in FIG. 6, the case bracket 250 includes a base wall 250a having a rectangular plate shape, an upper wall 250b and a lower wall 250c standing rearward from upper and lower ends of the base wall 250a, and left and right ends of the base wall 250a. Has a left wall 250d and a right wall 250e that are respectively erected rearward, and is formed into a rectangular container shape that is open to the rear as a whole, and the substrate case 220 is mounted in the internal space to accommodate the substrate case 220. Is configured to hold. The base wall 250a is formed with a plurality of screw insertion holes 251 penetrating in the front-rear direction (the present embodiment shows an example in which four screw insertion holes 251 are formed). Further, a rectangular caulking insertion hole 252 is formed in the left part of the base wall 250a so as to penetrate therethrough in the front-rear direction.

The back set board 30 is formed with screw insertion holes 36 at positions and numbers corresponding to the screw insertion holes 251 of the case bracket 250 penetrating forward and backward. Further, a caulking insertion hole 37 is formed in the back setting board 30 at a position corresponding to the caulking insertion hole 252 of the case bracket 250 so as to penetrate therethrough in the front-rear direction. A rectangular plate-shaped mounting base member 260 is provided on the front side of the back setting board 30. The mounting base member 260 is provided with screw holes 261 at positions and numbers corresponding to the screw insertion holes 251 of the case bracket 250. A base side caulking insertion portion 262 into which the main body caulking member 270 is inserted is provided on the left side of the mounting base member 260.

In order to attach the substrate case 220 configured as described above to the rear surface side of the back setting board 30, first, as shown in FIG. 6, the case bracket 250 is arranged behind the back setting board 30, and the back setting board 30 is arranged. The mounting base member 260 is arranged in front of. Then, the mounting screws 280 are respectively inserted from the rear into the four screw insertion holes 250 of the case bracket 250, and the mounting screws 280 are passed through the screw insertion holes 36 of the back setting board 30 to screw the mounting base member 260. By screwing into the hole 261, the case bracket 250 and the mounting base member 260 are fixed with the back setting board 30 sandwiched therebetween.

Next, as shown in FIG. 7, the main body caulking member 270 is inserted into the base side caulking insertion portion 262 of the mounting base member 260 from the rear through the caulking insertion holes 252 and 37 formed in the case bracket 250 and the back setting board 30. To install. Then, the board case 220 accommodating the main control board 210 is inserted into the case bracket 250 from the rear side. At this time, the main body caulking member 270 mounted on the base side caulking insertion portion 262 of the mounting base member 260 is inserted into the case side caulking insertion portion 226 of the substrate case 220. By engaging the main body caulking member 270 with the board case 220 and the mounting base member 260, the board case 220 is mounted in a state in which the rearward (removal direction) movement of the board case 220 with respect to the case bracket 250 is restricted.

When the board case 120 is attached in this manner, the main body caulking member 270 cannot be accessed unless the board case 220 or the like is destroyed, so that the board case 220 cannot be easily removed. In order to remove the substrate case 220, as shown in FIG. 8A, the portion near the case side caulking insertion portion 226 of the substrate case 220 (the portion A in FIG. 8A) is destroyed from the top case 231 side. Then, the main body caulking member 270 and the substrate case 220 are disengaged from each other (cut). By doing so, the restriction of the rearward (removal direction) movement of the substrate case 220 with respect to the case bracket 250 is released, and the substrate case 220 can be moved backward and removed from the case bracket 250.

When the board case 220 is removed from the case bracket 250 in this way, as shown in FIG. 8B, a clear breakage mark remains on the board case 220, and the main body caulking member 270 is attached to the base side of the mounting base member 260. The caulking insert portion 262 remains attached. However, as shown in FIG. 9, no traces of destruction or the like are left on the back setting board 30 and the case bracket 250. Therefore, when mounting the board case 220 accommodating and holding the new main control board 210, the back set board 30 and the case bracket 250 can be reused without replacement, and the mounting base member 260 and the main body caulking can be used. It is only necessary to replace the member 270 with a new one.

Next, a modification of the above embodiment will be described. In this modification, as shown in FIGS. 10 and 11, the mounting base member 260 ′ is mounted on the rear surface of the game board 100. The same components as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted. The mounting base member 260 ′ has a plurality of screw holes 261 and a base side caulking insertion portion 262, similarly to the mounting base member 260. The left and right ends of the mounting base member 260 ′ are each formed by bending them forward, and the front ends thereof are fixed to the rear surface of the game board 100 using a plurality of base mounting screws 265. Instead of using the base mounting screw 265, the mounting base member 260 ′ may be fixed to the game board 100 using an adhesive or the like. Since the mounting base member 260' is fixed to the game board 100 in this way, it is possible to further prevent the act of illegally removing the board case 220 together with the case bracket 250.

In the above-described embodiment, the pachinko gaming machine is described as an example of the gaming machine to which the present invention is applied, but the gaming machine is not limited to this. For example, a slot machine using a gaming medal (revolving cylinder). Type game machine), a spinning-ball type game machine using a game ball, a sparrow ball game machine, an arrange ball machine, and the like, and the same effects can be obtained.
