After the case caulking members 240 and 240'are attached to the bracket member 230, the substrate case 120 containing the main control board 110 inside the case is attached to the bracket member 230 as shown in FIG. To mount the board case 120, insert the case mounting protrusions 129 and 129 (see FIG. 3) provided on the right side of the board case 120 into the case mounting holes 239 and 239 (see FIG. 19) of the bracket member 230. Then, the left portion of the substrate case 120 is inserted into the bracket member 230. That is, the substrate case 120 is attached to the bracket member 230 by engaging the right side portion of the substrate case 120 with the bracket member 230 and then engaging the left side portion . When the board case 120 is attached to the bracket member 230 in this way, the locking claws 242a of the case caulking member 240 mounted on the caulking mounting portion 235 are arranged inside the cover portion 135 of the board case 120, and the locking claws 242a are arranged on the substrate. It is locked to the case mounting portion 125 (see FIG. 3) of the case 120. Therefore, the board case 120 is fixed so that it cannot be removed from the bracket member 230 unless the cover portion 135 and the case mounting portion 125 are broken to release the locked state from the case caulking member 240. Further, the substrate case 120 is locked by the case locking claw 234 of the bracket member 230.

Next, as shown in FIG. 21, the setting changing device 250 is attached to the lower right portion (lower position of the Nylatch attachment portion 237) in the bracket member 230. To mount the setting changing device 250, a mounting projection 256 (see FIG. 12) formed on the upper surface of the setting changing device 250 is engaged with the bracket member 230, and then a nylact (registered trademark) provided on the setting changing device 250 is provided. The setting change changing device 250 is fixed to the bracket member 230 using 257. Next, the cable harness K1 (see FIG. 23) extending from the setting change device 250 is connected to a predetermined electric connector mounted on the main control board 110 in the board case 120. Then, as shown in FIG. 22, the cover caulking member 256 (see FIG. 4) is attached to the bracket member 230, and the cable cover 255 is attached to the bracket member 230 so as to cover the cable harness K1. At this time, the locking claw of the cover caulking member 256 attached to the bracket member 230 is inserted into the locking groove of the cable cover 255, whereby the cable cover 255 is fixed so as not to be removed from the bracket member 230.

Then, as shown in FIG. 23, the cable harnesses K2 and K3 are connected to the plurality of electric connectors 112 and 113 (see FIG. 3) of the main control board 110 housed in the board case 120, respectively. Then, the cover caulking member 138 (see FIG. 3) is attached to the board case 120 (case lid 131), and the connector cover 145 is placed on the board so as to cover the connection portion (connector exposed portion 137) between the electric connector 112 and the cable harness K2. Attached to the case 120. At this time, the cover caulking member 138 mounted on the board case 120 (case lid 131) is arranged inside the connector cover 145, and the locking claw of the cover caulking member 138 is inserted into the locking groove in the connector cover 145. The cover. Therefore, the connector cover 145 is fixed so that it cannot be removed from the board case 120 unless the connector cover 145 is broken and the locked state with the cover caulking member 138 is released. The cable harnesses K2 and K3 connected to the main control board 110 are a cable locking tool 261 provided on the locking portion fixing portion 236a of the bracket member 230 and a cable locking tool provided on the left side plate 5a of the housing 5. It is locked and held by 261.

According to the board case mounting mechanism 200 having such a configuration, the bracket member 230 is rotatably mounted in the front-rear direction with respect to the left base member 210 fixed to the housing 5 (back plate 5e) by mounting screws. ing. Therefore, by rotating the bracket member 230 with respect to the left base member 210 without removing the substrate case 120 from the bracket member 230, the back surface of the substrate case 120 and the main control board 110 housed inside the case is illegal. It is possible to confirm whether or not any act has been performed. Further, a cable receiving portion 236 is formed in the bracket member 230, and a cable harness K3 or the like is locked by a cable locking tool 261 in the cable receiving portion 236. The main control board 110 uses a door relay terminal board (a board that manages the start lever 25, stop switches 26a to 26c, various display lamps, etc.) provided on the rear surface of the front door 2, a sub control board, and a cable harness. Since they are connected to each other, the routing of these cable harnesses is concentrated on the hinge side of the front door 2. Therefore, conventionally, it has been difficult for these cable harnesses to obstruct and rotate the bracket member significantly. However, according to the board case mounting mechanism 200 having the above configuration, since the bracket member 230 is provided with the cable receiving portion 236, the cable harness is received in the cable receiving portion 236 when the bracket member 230 is rotated. This allows the bracket member 230 to be largely rotated (nearly 90 degrees) to a position close to the left side plate 5a of the housing 5.

The bracket member 230 inserts the three bracket-side engaging portions 231 to 233 into the base-side engaging portions 211 to 213 of the left-side base member 210 and slides them upward to slide the three bracket-side engaging portions 231 to 233, respectively. The rotating shafts 231b to 233b of the above are inserted into and engaged with the shaft insertion holes 211b to 213b of the base side engaging portions 211 to 213, respectively. Then, the bracket member 230 is rotated about 90 degrees in a direction (rearward) in which the rear surface of the bracket member 230 approaches the back plate 5e of the housing 5 around the rotation shafts 231b to 233b, whereby the bracket member 230 is moved to the left base member 210. It is designed to be installed with the downward movement restricted by. In the conventional shaft mounting structure in which the bracket member is hooked from top to bottom, there is a problem that a dead space is formed between the top plate of the housing and the bracket member by the length of the shaft. .. However, according to the above configuration, the upper surface of the bracket member 230 can be attached in a state of being close to the lower surface of the top plate 5c of the housing 5. Therefore, the bracket member 230 and the substrate case 120 can be arranged in the housing 5 without creating a dead space between the top plate 5c and the bracket member 230.

The tip (left end) of the case caulking members 240, 240'attached to the bracket member 230 protrudes to the left from the left wall of the bracket member 230, and the tip of the case caulking member 240, 240'conducts to the left. The heads of the mounting screws inserted into the screw insertion holes 211a and 212a of the left base member 210 are covered and hidden. Therefore, access to the mounting screws for fixing the left base member 210 to the housing 5 can be restricted, and the board case 120 (main control board 110) can be mounted from the housing 5 together with the left base member 210 and the bracket member 230. It is possible to prevent the act of illegally removing it.

The substrate case 120 is attached to the bracket member 230 by engaging the left side portion of the substrate case 120 with the bracket member 230 and then engaging the right portion thereof. Therefore, when the board case 120 is attached to and detached from the bracket member 230, it becomes difficult to attach and detach the board case 120 unless the front door 2 that opens to the right is opened widely. Therefore, it is possible to prevent the act of illegally attaching and detaching the substrate case 120.

The setting changing device 250 is attached to the bracket member 230 together with the board case 120. Therefore, the setting changing device 250 can be arranged near the main control board 110 in the board case 120, and the cable harness K1 connecting the main control board 110 and the setting changing device 250 can be easily routed. Further, the setting changing device 250 is attached to the lower right portion in the bracket member 230. Therefore, when changing the set value of the slot machine 1, the setting value can be changed by operating the setting changing device 250 simply by opening the right-opening front door 2 a little.

Next, a modified mode of the above embodiment will be described. The left side base member 210 and the connector cover 145 described above may be changed like the left side base member 310 and the connector cover 345 shown in FIGS. 24 to 27. The parts having the same configuration as the left base member 210 and the connector cover 145 are designated by the same reference numerals as those in the above embodiment, and the description of the configuration will be omitted. As shown in FIGS. 24 and 25, grooves 311, 312 extending in the left-right direction are formed on the front surface of the left base member 310 at the left positions of the upper and lower screw insertion holes 211a and 212a, respectively.

As shown in FIGS. 26 and 27, the connector cover 345 is formed in a shape extending to the left of the connector cover 145 described above, and screw covering portions 345a and 345b extending downward are vertically extended to the left end portion thereof. Two are formed. When the connector cover 345 is attached to the board case 120 (case lid 131), the cover caulking member 138 attached to the caulking attachment portion 139 of the case lid 131 is arranged inside the connector cover 345, and the cover caulking member 138 is engaged. The clasp is inserted into the locking groove in the connector cover 345. Therefore, the connector cover 345 is fixed so that it cannot be removed from the board case 120 unless the connector cover 345 is broken and the locked state with the cover caulking member 138 is released (see FIG. 28). ).

As shown in FIGS. 29 and 30, the screw covering portions 345a and 345b of the connector cover 345 attached to the board case 120 are the heads of the mounting screws inserted into the screw insertion holes 211a and 212a of the left base member 310, respectively. It is designed to cover and hide. The head of the mounting screw inserted into the screw insertion hole 212a is already covered by the screw cover 215 as described above, but the front side thereof is further covered by the screw covering portion 345b of the connector cover 345. It has become like.

Even when the connector cover 345 is attached in this way, as shown in FIGS. 31 and 32, the bracket member 230 can rotate in the front-rear direction with respect to the left base member 310, and this rotation can be performed. Grooves 311, 312 are formed in the left base member 310 to enable it. When the bracket member 230 is rotated to a position close to the left side plate 5a of the housing 5, the screw covering portions 345a and 345b of the connector cover 345 are fitted into the grooves 31 and 312 of the left side base member 310. As a result, the screw covering portions 345a and 345b do not interfere with (collide) with the left base member 310 and hinder the rotation of the bracket member 230 (see FIG. 32).

According to the left base member 310 and the connector cover 345 having such a configuration, the screw covering portions 345a and 345b of the connector cover 345 insert the heads of the mounting screws inserted into the screw insertion holes 211a and 212a of the left base member 310. It is designed to cover and hide. Therefore, access to the mounting screws for fixing the left base member 310 to the housing 5 can be restricted, and the board case 120 (main control board 110) is mounted from the housing 5 together with the left base member 310 and the bracket member 230. It is possible to prevent the act of illegally removing it. Further, since the groove portions 311, 312 are formed in the left side base member 310, the bracket member 230 can be rotated with respect to the left side base member 310.

Further, as shown in FIG. 33, the above-mentioned setting changing device 250 is not attached to the bracket member 230, but the rotating shafts 231b to 233b (engagement with the left base member 210) which are the rotation centers of the bracket member 230. It may be provided on the upper part of the left side plate 5a of the housing 5, which is located near the portion). Alternatively, as shown in FIG. 34, the setting changing device 250 may be provided on the upper portion of the back plate 5e of the housing 5. By arranging the setting changing device 250 near the rotation center of the bracket member 230 in this way, it is easy to route the cable harness that connects the main control board 110 attached to the bracket 230 and the setting changing device 250. It becomes.

In the above embodiment, the rotating shafts 231b to 233b extending above the bracket member 230 are inserted into the shaft insertion holes 211b to 213b opened below the left base member 210 (310), and the bracket member 230 is inserted into the left base. Although it is configured to engage with the member 210 (310), the bracket member 230 has a shaft insertion hole opened downward, and the left base member 210 (310) has a rotating shaft extending upward. May be good. Even with such a configuration, the bracket member 230 is attached to the left base member 210 (310) in the same manner as the above configuration, and the same effect as the above configuration can be obtained.

In the above-described embodiment, in the left base member 210, the screw cover 215 is inserted only into the middle base side engaging portion 212 to cover the screw insertion hole 212a in the middle base side engaging portion 212. The screw cover 215 may also be inserted into the upper base side engaging portion 211 so as to cover the screw insertion hole 211a in the upper base side engaging portion 211. At this time, it is not necessary to form the two protrusions 216 in the upper base side engaging portion 211. If the two screw covers 215 are used to cover both the screw insertion holes 211a and 212a in this way, unauthorized access to the mounting screws attached to these insertion holes can be further prevented. Further, both the screw insertion holes 211a and 212a may be integrally covered with one screw cover.
