  The procedure for attaching main controller 100 configured as described above to the upper portion of the 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 positioning protrusions 217 and 218 (see FIG. 5) into positioning holes formed in the left 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 the mounting screws. At this time, it is attached so that the upper surface of the left base member 210 contacts the lower surface of the top plate 5c of the housing 5. The right base member 220 is positioned by inserting positioning protrusions 223a (see FIG. 8) and the like into positioning holes formed in the right 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, respectively, and the right base member 220 is fixed to the back plate 5e by the mounting screws.

  Next, as shown in FIG. 14, the screw cover 215 is inserted from the front into the middle base-side engaging portion 212 of the left base member 210 and attached. When the screw cover 215 is mounted in the middle base side engaging portion 212, the head of the mounting screw inserted into the screw insertion hole 212a is in a state of being covered by 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 5 a 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 of the middle base side engaging portion 212 as described above, the middle 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, and the rotating shafts 231b to 233b of the bracket side engaging portions 231 to 233 are respectively inserted into the shaft insertion 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) where the rear surface of the bracket member 230 approaches the back plate 5e of the housing 5, and as shown in FIG. 15 is rotated substantially 90 degrees rearward from the state shown in FIG. 15 (to a 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 supporting wall portions 211c to 213c of the base side engaging portions 211 to 213. Thus, 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 support wall portion 215c of the screw cover 215). That is, the bracket member 230 is restricted from moving down by the bracket support wall portions 211c to 213c (the cover-side support wall portion 215c). At this time, the guide projections 238 and 238 on the rear surface of the bracket member 230 are inserted into the front ends of the screw insertion holes 221 and 221 of the right base member 220, so that the upper, lower, left, and right positions of the bracket member 230 are adjusted. Then, the right part of the bracket member 230 is locked to the right base member 220 by the Nylatch (registered trademark) attached to the nilac attachment part 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 bracket member 230 is attached such that the upper surface of the bracket member 230 is close to the lower surface of the top plate 5c of the housing 5.

  Next, as shown in FIG. 19, the case caulking members 240 are inserted into the caulking mounting portions 235 and 235 of the bracket member 230 from the right side, and mounted. In the present embodiment, the lower caulking attachment portion 235 has a case caulking member 240 ′ (dummy case) having a configuration in which the above-described case caulking member 240 does not have the locking portion 242 (locking claw 242 a). Caulking member). When the case caulking members 240, 240 'are mounted on the caulking mounting portions 235, 235, the tip portions (left ends) of the case caulking members 240, 240' project to the left from the left side wall of the bracket member 230, and the case caulking is performed. The distal ends of the members 240 and 240 'cover and cover the heads of the mounting screws inserted into the screw insertion holes 211a and 212a of the left base member 210. Although the head of the mounting screw inserted into the screw insertion hole 212a is already covered by the screw cover 215 as described above, the front side is further covered by the tip of the case caulking member 240 '. It has become.

  Since the front ends (left ends) of the case caulking members 240 and 240 ′ project leftward from the left side wall of the bracket member 230, the bracket member 230 is substantially parallel to the left side plate 5 a of the housing 5. Even if the bracket is rotated to the state (the state shown in FIG. 17), the lower surfaces of the case caulking members 240 and 240 ′ abut against 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 ′ contacts the inner surface of the screw cover 215). That is, the case caulking members 240 and 240 'restrict the bracket member 230 from dropping.

After attaching the case caulking members 240 and 240 'to the bracket member 230, the board case 120 accommodating 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 projections 129, 129 (see FIG. 3) provided on the right side of the board case 120 into the case mounting holes 239, 239 (see FIG. 19) of the bracket member 230. Then, the left part of the board 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 substrate case 120 is attached to the bracket member 230 in this manner, the locking claws 242a of the case caulking member 240 mounted on the caulking mounting portion 235 are disposed inside the cover portion 135 of the substrate case 120, and the locking claws 242a are The case 120 is locked to a case mounting portion 125 (see FIG. 3). Therefore, the board case 120 is fixed so that the board case 120 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 with the case caulking member 240. The board case 120 is locked by a case locking claw 234 of the bracket member 230.

  Next, as shown in FIG. 21, the setting change device 250 is attached to a lower right portion (a position below the nail latch attachment portion 237) inside the bracket member 230. To attach the setting change device 250, a mounting protrusion 256 (see FIG. 12) formed on the upper surface of the setting change device 250 is engaged with the bracket member 230, and then the Nylatch (registered trademark) provided on the setting change device 250 is provided. The setting change / change 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 electrical 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 claws of the cover caulking member 256 attached to the bracket member 230 are inserted into the locking grooves of the cable cover 255, thereby fixing the cable cover 255 so that the cable cover 255 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 electrical 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 attached to the board so as to cover the connection portion (connector exposed portion 137) between the electrical connector 112 and the cable harness K2. Attach to case 120. At this time, the cover caulking member 138 attached to the board case 120 (case lid 131) is disposed inside the connector cover 145, and the locking claws of the cover caulking member 138 are inserted into the locking grooves in the connector cover 145. You. Therefore, the connector cover 145 is fixed so that the connector cover 145 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 include a cable locking tool 261 provided on the locking section fixing portion 236a of the bracket member 230 and a cable locking tool provided on the left side plate 5a of the housing 5. 261 are locked and held.

According to the board case attachment mechanism 200 having such a configuration, the bracket member 230 is attached to the left base member 210 fixed to the housing 5 (the back plate 5e) with attachment screws so as to be rotatable in the front-rear direction. ing. Therefore, by rotating the bracket member 230 with respect to the left 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 illegally attached. It is possible to confirm whether an act or the like has been performed. 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 includes a door relay terminal board (start lever 25, stop switch 26a) provided on the rear surface of the front door 2.
26c, a board that manages various display lamps, etc.) and a sub-control board using a cable harness, so that the wiring of these cable harnesses is concentrated on the hinge side of the front door 2. Therefore, conventionally, it was difficult for these cable harnesses to hinder and to rotate the bracket member largely. However, according to the board case mounting mechanism 200 having the above configuration, since the cable receiving portion 236 is provided on the bracket member 230, the cable harness is received in the cable receiving portion 236 when the bracket member 230 is rotated. As a result, the bracket member 230 can be largely rotated to a position close to the left side plate 5a of the housing 5 (near 90 degrees).

  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, respectively, and slides the same upward, so that the bracket-side engaging portions 231 to 233 are moved. 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 engaged therewith. 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 about the rotation shafts 231b to 233b, so that the bracket member 230 is moved to the left base member 210. It is designed to be mounted in a state where downward movement is restricted. In the conventional shaft mounting structure in which the bracket member is hooked downward from above, 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 mounted 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 board case 120 can be disposed in the housing 5 without producing a dead space between the top plate 5c and the bracket member 230.

  The distal ends (left ends) of the case caulking members 240 and 240 'attached to the bracket member 230 project to the left from the left side wall of the bracket member 230, and the distal ends of the case caulking members 240 and 240' The head of the mounting screw inserted into the screw insertion holes 211a and 212a of the left base member 210 is covered and hidden. Therefore, access to the mounting screw 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 removed from the housing 5 together with the left base member 210 and the bracket member 230. Acts such as unauthorized removal can be prevented.

  The board case 120 is attached to the bracket member 230 by engaging the left side of the board case 120 with the bracket member 230 and then engaging the right side. Therefore, when attaching and detaching the board case 120 to and from the bracket member 230, it is difficult to perform the attaching and detaching work of the board case 120 unless the front door 2 that opens to the right is largely opened. Therefore, the act of illegally attaching and detaching the board case 120 can be prevented.

  The setting change device 250 is attached to the bracket member 230 together with the board case 120. Therefore, the setting change device 250 can be disposed near the main control board 110 in the board case 120, and the routing of the cable harness K1 connecting the main control board 110 and the setting change device 250 is facilitated. The setting change device 250 is attached to the lower right inside the bracket member 230. Therefore, when changing the set value of the slot machine 1, the setting change device 250 can be operated to change the set value only by slightly opening the front door 2 that opens rightward.

Next, a modification of the above embodiment will be described. The above-described left base member 210 and connector cover 145 may be modified like the left base member 310 and connector cover 345 shown in FIGS. The same components as those of the left base member 210 and the connector cover 145 described above are denoted by the same reference numerals as those of the above-described embodiment, and the description of the components is 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, 212a, respectively.

  As shown in FIGS. 26 and 27, the connector cover 345 is formed in a shape extending leftward from the above-described connector cover 145, and has screw coating portions 345a and 345b extending downward at its left end. 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 pawl is inserted into a locking groove in the connector cover 345. Therefore, the connector cover 345 is fixed so that the connector cover 345 cannot be removed from the board 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 cover portions 345a and 345b of the connector cover 345 attached to the board case 120 are the heads of the attachment screws inserted into the screw insertion holes 211a and 212a of the left base member 310, respectively. To cover and hide. Although the head of the mounting screw inserted into the screw insertion hole 212a is already covered by the screw cover 215 as described above, the screw cover 345b of the connector cover 345 further covers the front side. It has become.

  Even when the connector cover 345 is attached in this manner, 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. To allow this, grooves 311, 312 are formed in the left base member 310. When the bracket member 230 is rotated to a position approaching the left side plate 5 a of the housing 5, the screw coating portions 345 a and 345 b of the connector cover 345 fit into the grooves 311 and 312 of the left base member 310. Accordingly, the screw coating portions 345a and 345b do not interfere (collide) with the left base member 310 and do not 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 are attached to the heads of the mounting screws inserted into the screw insertion holes 211a and 212a of the left base member 310. Cover and hide. Therefore, access to the mounting screw for fixing 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. Acts such as unauthorized removal can be prevented. Further, since the grooves 311 and 312 are formed in the left base member 310, the bracket member 230 can be rotated with respect to the left base member 310.

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

In the above-described embodiment, the rotation 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 member. The bracket 210 is configured to be engaged with the member 210 (310).
A configuration in which a rotation shaft extending upward is formed in (310) may be employed. Even in such a configuration, the bracket member 230 is attached to the left base member 210 (310) as in the above configuration, and the same effects as in the above configuration can be obtained.

  In the above-described embodiment, the screw cover 215 is inserted only into the middle base-side engaging portion 212 of the left base member 210 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, a configuration may be adopted in which both the screw insertion holes 211a and 212a are integrally covered with one screw cover.

  In the above-described embodiment, the setting change device 250 is configured to include the setting change key cylinder 251 and the setting change switch 252. However, the setting change device 250 includes one of the setting change key cylinder 251 and the setting change switch 252. Any configuration may be used. In that case, the other side may be provided separately from the setting change device 250 at another location such as the rear surface of the front door 2. In the above-described embodiment, the display unit 116 for displaying the set value of the slot machine 1 (such as the winning probability of a gaming role) is provided on the main control board 110. Alternatively, they may be provided independently at a position near the setting change device 250 or at the rear surface of the front door 2. Alternatively, the display unit may be provided integrally with the setting change device 250. Alternatively, the set value may be displayed using the stored number display lamp 46h or the number-of-payouts display lamp 46j provided on the front surface of the front door 2, and in that case, there is no need to separately provide the display unit.

  In the above-described embodiment, the mounting mechanism of the board case 120 that houses the main control board 110 has been described. However, the board case that houses the sub-control board that performs various effect controls also has the same configuration as the case mounting mechanism 200 described above. You may make it attach by an attachment mechanism. In the above-described embodiment, Nylatch (registered trademark) is used to fix the bracket member 230 and the setting change device 250. However, Niflac (registered trademark), a lever clip, or the like may be used instead.

  In the above-described embodiment, the slot machine (turning machine) using a game medal is described as an example of the gaming machine to which the present invention is applied. However, the invention is not limited to this. The same effects can be obtained by applying the same to other game machines such as a pachinko machine, a spinning game machine using a game ball, a sparrow ball game machine, and an arrangement ball machine.
