A procedure for attaching main controller 100 configured in this way to the upper inner surface of back plate 5e of housing 5 will be described with reference to FIGS. First, as shown in FIG. 13, the left base member 210 and the right base member 220 are attached to the back plate 5e. The left base member 210 is positioned by inserting the positioning protrusions 217 and 218 (see FIG. 5) into the positioning holes formed in the left side plate 5a and the back plate 5e of the housing 5. Then, mounting screws are respectively inserted into the upper and lower screw insertion holes 211a and 212a from the front, and the left base member 210 is fixed to the back plate 5e by these mounting screws. At this time, the upper surface of the left base member 210 is attached so as to contact the lower surface of the top plate 5c of the housing 5. The right base member 220 is positioned by inserting the positioning protrusions 223a (see FIG. 8) and the like into the positioning holes formed in the right side plate 5b and the back plate 5e of the housing 5. Then, mounting screws are inserted into the upper and lower screw insertion holes 221 from the front, and the right side base member 220 is fixed to the back plate 5e by these mounting screws.

Next, as shown in FIG. 14, the screw cover 215 is inserted from the front into the inside base side engaging portion 212 of the left side base member 210 and attached. When the screw cover 215 is attached inside the middle base side engaging portion 212, the head portion of the attachment screw inserted into the screw insertion hole 212a is covered with the screw cover 215.

Then, as shown in FIGS. 15 and 16, the bracket member 230 is set to be substantially parallel to the left side plate 5a of the housing 5, and the three bracket side engaging portions 231 to 233 are respectively attached to the left base member 210. It is inserted into the base side engaging portions 211 to 213. Since the screw cover 215 is attached to the inside base side engaging portion 212 as described above, the inside bracket side engaging portion 232 is inserted into the screw cover 215. Then, as shown in FIG. 17, the bracket member 230 is slid upward so that the rotation shafts 231b to 233b of the bracket side engaging portions 231 to 233 are respectively inserted into the shaft inserting holes 211b of the base side engaging portions 211 to 213. ˜213b. At this time, the bracket member 230 is in a state of being rotatably engaged with the left base member 210 about the rotation shafts 231b to 233b.

Then, the bracket member 230 is rotated around the rotation shafts 231b to 233b in a direction (rearward) in which the rear surface of the bracket member 230 approaches the back plate 5e of the housing 5, and as shown in FIG. The 230 is rotated backward from the state shown in FIG. 15 by approximately 90 degrees (to the position where the rear surface of the bracket member 230 is close to the back plate 5e of the housing 5). When the bracket member 230 is rotated in this manner, the lower surfaces of the base portions 231a to 233a of the bracket side engaging portions 231 to 233 come into contact with the upper surfaces of the bracket support wall portions 211c to 213c of the base side engaging portions 211 to 213. The bracket member 230 is supported so as not to move downward (the lower surface of the middle bracket side engaging portion 233 contacts the upper surface of the cover side supporting wall portion 215c of the screw cover 215). That is, downward movement of the bracket member 230 is restricted by the bracket support wall portions 211c to 213c (cover side support wall portion 215c). At this time, the guide protrusions 238 and 238 on the rear surface of the bracket member 230 are inserted into the front end portions of the screw insertion holes 221 and 221 of the right base member 220 to adjust the vertical and horizontal positions of the bracket member 230. Then, the right portion of the bracket member 230 is locked to the right base member 220 by the Nylatch (registered trademark) attached to the Nylatch attachment portion 237 of the bracket member 230, and the bracket member 230 is attached to the left and right base members 210, 220. .. At this time, the upper surface of the bracket member 230 is attached in a state of being close to the lower surface of the top plate 5c of the housing 5.

Next, as shown in FIG. 19, the case caulking member 240 is inserted from the right side into the caulking mounting portions 235 and 235 of the bracket member 230 and mounted. In this embodiment, the case caulking member 240' (dummy case) is configured such that the case caulking member 240 described above does not include the engaging portion 242 (engaging claw 242a) in the lower caulking mounting portion 235. The caulking member) is attached. When the case caulking members 240 and 240' are attached to the caulking attachment portions 235 and 235, the tip portions (left end portions) of the case caulking members 240 and 240' are protruded leftward from the left side wall of the bracket member 230, and the case caulking members are attached. The tip ends of the members 240 and 240' cover and cover the heads of the mounting screws inserted in the screw insertion holes 211a and 212a of the left base member 210. The head of the mounting screw inserted into the screw insertion hole 212a is already covered with the screw cover 215 as described above, but the front side thereof is further covered with the tip of the case caulking member 240'. It is like this.

Since the tip portions (left end portions) of the case caulking members 240 and 240' are in a state of protruding leftward from the left side wall of the bracket member 230, the bracket member 230 is substantially parallel to the left side plate 5a of the housing 5. Even when rotated to the state (the state shown in FIG. 17), the lower surfaces of the case caulking members 240 and 240' abut the inner surfaces of the base side engaging portions 211 and 212 of the left base member 210, and the bracket member 230 is supported. (The lower surface of the case caulking member 240' abuts on the inner surface of the screw cover 215). That is, the case caulking members 240 and 240 ′ prevent the bracket member 230 from falling.

After mounting the case caulking members 240 and 240 ′ on the bracket member 230, as shown in FIG. 20, the board case 120 containing the main control board 110 inside the case is mounted on the bracket member 230. To mount the board case 120, the case mounting protrusions 129, 129 (see FIG. 3) provided on the right side of the board case 120 are inserted into the case mounting holes 239, 239 (see FIG. 19) of the bracket member 230. Then, the left part of the substrate case 120 is inserted into the bracket member 230. That is, the board case 120 is attached to the bracket member 230 by engaging the left side portion of the board case 120 with the bracket member 230 and then engaging the right side portion. When the board case 120 is thus attached to the bracket member 230, the locking claws 242a of the case caulking member 240 mounted on the caulking mounting portion 235 are arranged inside the cover part 135 of the board case 120, and the locking claws 242a are mounted on the board. The case 120 is locked to the case mounting portion 125 (see FIG. 3). Therefore, the substrate case 120 is fixed so that it cannot be removed from the bracket member 230 unless the cover portion 135 and the case attachment portion 125 are broken to release the locked state with the case caulking member 240. The board 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 of the bracket member 230 (the position below the nail latch attachment portion 237). The setting change device 250 is mounted by engaging a mounting protrusion 256 (see FIG. 12) formed on the upper surface of the setting change device 250 with the bracket member 230, and then installing the Nylatch (registered trademark) provided in the setting change device 250. The setting change changing device 250 is fixed to the bracket member 230 by using 257. Next, the cable harness K1 (see FIG. 23) extending from the setting changing 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, a 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 claws of the cover caulking member 256 mounted on the bracket member 230 are inserted into the locking grooves of the cable cover 255, thereby fixing the cable cover 255 so that it cannot 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 mounted on the board so as to cover the connection portion (connector exposed portion 137) between the electric connector 112 and the cable harness K2. Attach to the case 120. At this time, the cover caulking member 138 mounted on the substrate case 120 (case lid 131) is arranged inside the connector cover 145, and the locking claws of the cover caulking member 138 are inserted into the locking grooves inside the connector cover 145. It Therefore, the connector cover 145 is fixed so that it cannot be removed from the substrate case 120 unless the connector cover 145 is broken to release the locked state with the cover caulking member 138. The cable harnesses K2 and K3 connected to the main control board 110 include a cable locking tool 261 provided on the locking part 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 attaching mechanism 200 having such a configuration, the bracket member 230 is attached to the left base member 210 fixed to the housing 5 (back plate 5e) by the attaching screw so as to be rotatable in the front-rear direction. ing. Therefore, by rotating the bracket member 230 with respect to the left-side base member 210 without removing the board case 120 from the bracket member 230, the back surface of the board case 120 and the main control board 110 housed inside the case is tampered with. It is possible to confirm that no action has been taken. Further, a cable receiving portion 236 is formed on the bracket member 230, and the cable harness K3 and the like are locked by a cable locking tool 261 in the cable receiving portion 236. The main control board 110 uses a cable harness with 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 and a sub-control board. Since they are connected together, the routing of these cable harnesses is concentrated on the hinge side of the front door 2. Therefore, conventionally, it has been difficult to rotate the bracket member largely because these cable harnesses interfere with each other. However, according to the board case mounting mechanism 200 having the above-described configuration, since the bracket member 230 is provided with the cable receiving portion 236, when the bracket member 230 is rotated, the cable harness is received in the cable receiving portion 236. Therefore, the bracket member 230 can be largely rotated (close to 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 base member 210 and slides the bracket-side engaging portions 231 to 233 upward, respectively. The rotating shafts 231b to 233b are inserted into the shaft insertion holes 211b to 213b of the base side engaging portions 211 to 213, respectively, and are engaged with each other. Then, the bracket member 230 is rotated about 90 degrees in the direction (rearward) in which the rear surface of the bracket member 230 approaches the back plate 5e of the housing 5 about the rotation shafts 231b to 233b, so that the bracket member 230 is left side base member 210. It is designed to be attached with the downward movement restricted. 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 bracket member 230 can be attached in a state where the upper surface of the bracket member 230 is 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 a dead space between the top plate 5c and the bracket member 230.

The tip portions (left end portions) of the case caulking members 240 and 240' mounted on the bracket member 230 are in a state of protruding leftward from the left side wall of the bracket member 230, and the tip portions of the case caulking members 240 and 240' are 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 screw that fixes the left base member 210 to the housing 5 can be restricted, and the board case 120 (main control board 110) can be removed from the housing 5 together with the left base member 210 and the bracket member 230. It is possible to prevent illegal removal.

The board case 120 is attached to the bracket member 230 by engaging the left side portion of the board case 120 with the bracket member 230 and then engaging the right side portion. Therefore, when the substrate case 120 is attached to and detached from the bracket member 230, it is difficult to attach and detach the substrate case 120 unless the right-opening front door 2 is opened greatly. 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 substrate case 120. Therefore, the setting change 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 change device 250 can be easily handled. The setting changing device 250 is attached to the lower right part of the bracket member 230. Therefore, when changing the setting value of the slot machine 1, the setting changing device 250 can be operated to change the setting value by simply opening the front door 2 that opens to the right.

Next, a modification of the above embodiment will be described. The left side base member 210 and the connector cover 145 described above may be changed to the left side base member 310 and the connector cover 345 shown in FIGS. 24 to 27. In addition, the same reference numerals as those in the above-described embodiment are given to the portions having the same configurations as the above-mentioned left side base member 210 and the connector cover 145, and the configuration description will be omitted. As shown in FIGS. 24 and 25, on the front surface of the left-side base member 310, groove portions 311 and 312 extending in the left-right direction are formed at 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 above-described connector cover 145, and has screw cover portions 345a and 345b extending downward at the left end thereof. Two are formed. When the connector cover 345 is attached to the substrate case 120 (case lid 131), the cover crimp member 138 mounted on the crimp mounting portion 139 of the case lid 131 is disposed inside the connector cover 345, and the cover crimp member 138 is engaged. The stop claw is adapted to be 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 substrate case 120 unless the connector cover 345 is broken to release the locked state with the cover caulking member 138 (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 attaching 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 with the screw cover 215 as described above, but the front side thereof is further covered with the screw covering portion 345b of the connector cover 345. It is like this.

Even when the connector cover 345 is attached in this way, as shown in FIGS. 31 and 32, the bracket member 230 is rotatable in the front-rear direction with respect to the left base member 310, and this rotation is not possible. Grooves 311 and 312 are formed in the left-side base member 310 to make it possible. When the bracket member 230 is rotated to a position approaching the left side plate 5a of the housing 5, the screw cover portions 345a and 345b of the connector cover 345 are fitted into the groove portions 311 and 312 of the left side base member 310. As a result, the screw covering portions 345a and 345b do not interfere (collide) with the left base member 310 and prevent the bracket member 230 from rotating (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 prevent the heads of the mounting screws inserted into the screw insertion holes 211a and 212a of the left base member 310, respectively. It is supposed to cover and hide. Therefore, access to the mounting screw that fixes the left base member 310 to the housing 5 can be restricted, and the board case 120 (main control board 110) can be removed from the housing 5 together with the left base member 310 and the bracket member 230. It is possible to prevent illegal removal. Moreover, since the groove portions 311 and 312 are formed in the left base member 310, it is possible to rotate the bracket member 230 with respect to the left base member 310.

In addition, as shown in FIG. 33, the setting change device 250 is not attached to the bracket member 230, but the rotation shafts 231b to 233b (the engagement with the left base member 210) which are the rotation centers of the bracket member 230. It may be provided on the left side plate 5a of the housing 5, which is a position near the (part). Alternatively, as shown in FIG. 34, the setting changing device 250 may be provided above the back plate 5e of the housing 5. By disposing the setting changing device 250 in the vicinity of the rotation center of the bracket member 230 in this way, it is easy to handle the cable harness connecting the main control board 110 attached to the bracket 230 and the setting changing device 250. Becomes

In the above-described embodiment, the rotary 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) to move the bracket member 230 to the left base member. The configuration is such that the bracket 210 is engaged with the member 210 (310), but the bracket member 230 is formed with a shaft insertion hole opening downward, and the left base member 210 (310) is formed with a rotating shaft extending upward. Good. Even with such a configuration, the bracket member 230 is attached to the left base member 210 (310) similarly to 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 in 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 be inserted also in 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, the two protrusions 216 may not be formed in the upper base side engaging portion 211. In this way, if the two screw covers 215 are used to cover both the screw insertion holes 211a and 212a, it is possible to further prevent unauthorized access to the attachment screws attached to these insertion holes. Further, one screw cover may integrally cover both the screw insertion holes 211a and 212a.

In the above-described embodiment, the setting change device 250 is configured to have the setting change key cylinder 251 and the setting change switch 252, but is provided with either the setting change key cylinder 251 or the setting change switch 252. It is sufficient if it has a different configuration. In that case, the other may be provided separately from the setting changing device 250 at another location such as the rear surface of the front door 2. In the above-described embodiment, the display unit 116 that displays the set value of the slot machine 1 (probability of winning the game, etc.) is provided on the main control board 110. However, this display section is not provided on the main control board 110. Instead, it may be provided independently at a position near the setting changing device 250, a rear surface of the front door 2, or the like. Alternatively, the display unit may be provided integrally with the setting changing device 250. Alternatively, the set value may be displayed using the stored number display lamp 46h or the payout number display lamp 46j provided on the front surface of the front door 2, and in that case, it is not necessary to separately provide the display section.

In the above embodiment, the mounting mechanism of the substrate case 120 accommodating the main control substrate 110 has been described. However, the substrate case accommodating the sub control substrate for performing various effect controls has the same configuration as the case mounting mechanism 200. It may be attached by an attachment mechanism. In the above-described embodiment, the Nylatch (registered trademark) is used to fix the bracket member 230 and the setting changing device 250, but instead of this, a Niflac (registered trademark), a lever clip, or the like may be used.

In the above-described embodiment, as an example of the gaming machine to which the present invention is applied, a slot machine (spindle-type gaming machine) using gaming medals has been described as an example, but the invention is not limited to this, and for example, , A pachinko machine, a spinning-ball type game machine using a game ball, a sparrow ball game machine, an arrange ball machine, and the like can be similarly applied and the same effect can be obtained.
