It is designed to be inserted into the stop groove. Therefore, the cable cover 255 is fixed so that it cannot be removed from the bracket member 230 unless the cable cover 255 is broken and the locked state with the cover caulking member 256 is released.

  The setting change device 250 is a device that is operated when changing a setting value (such as a winning probability of a game player) of the slot machine 1 that determines the degree of advantage for the player. As shown in FIG. A cylinder 251, a setting change switch 252, and an opening / closing door 253 attached so as to cover the key cylinder 251 and the switch 252 are configured. The setting change device 250 is provided in the lower part of the housing 5 in a state in which a setting change key (not shown) is inserted into the setting change key cylinder 251 and rotated about 90 degrees clockwise (clockwise). When the power switch of the power supply 55 is turned on, the setting change mode is activated. Each time the setting change switch 252 is pressed, the setting values in the six stages 1 to 6 are switched, and the setting values are displayed on the display unit 116 provided on the main control board 110. When the start lever 25 provided on the front surface of the front door 2 is operated, the set value is confirmed, and when the setting change key is returned to the original position, the setting change mode is terminated and the normal mode is entered. The main control board 110 activates the setting confirmation mode when the setting change key inserted into the setting change key cylinder 251 is rotated about 90 degrees clockwise (clockwise) in the normal mode. The current set value is displayed on the display unit 116 on the main control board 110. When the setting change key is returned to the original position, the setting change mode is terminated and the normal mode is entered. In the present embodiment, since the display unit 116 for displaying the set value is provided on the main control board 110 as described above, the stored number display lamp 46h or the payout number display lamp 46j provided on the front surface of the front door 2. The set value is not displayed using.

  The setting change switch 252 functions as a switch for switching setting values in the setting change mode, but reset processing for canceling various error states (such as hopper empty) occurring in the slot machine 1 in the normal state. It functions as a switch for performing. That is, when the setting change switch 252 is operated during the occurrence of an error in the normal state, the main control board 110 cancels the error state when the error factor is eliminated. In the present embodiment, the setting change switch 252 functions as a reset switch that cancels various error states. However, a means different from the setting change switch 252 may be provided. For example, by using a door opening key cylinder and a door opening key (both not shown) for opening the front door 2, the door opening key is the opening direction of the front door 2 with respect to the door opening key cylinder. It is also conceivable to cancel the error state using an input signal generated by rotating in the opposite direction.

  A procedure for attaching main controller 100 configured in this manner to the upper part 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 5 a and the back plate 5 e 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 left base member 210 is attached so that the upper surface thereof is in contact with the lower surface of the top plate 5 c 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 respectively inserted into the upper and lower screw insertion holes 221 from the front, and the right 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 into the middle base side engaging portion 212 of the left base member 210 from the front and attached. When the screw cover 215 is attached in the middle base side engaging portion 212, the head of the attachment screw inserted into the screw insertion hole 212a is covered with the screw cover 215.

15 and 16, the bracket member 230 is attached to the left side plate 5 of the housing 5.
The three bracket side engaging portions 231 to 233 are inserted into the base side engaging portions 211 to 213 of the left base member 210, respectively, in a state substantially parallel to a. Since the screw cover 215 is attached in 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 rotation 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. Insert into ~ 213b. At this time, the bracket member 230 is engaged with the left base member 210 so as to be rotatable about the rotation shafts 231b to 233b.

  Then, the bracket member 230 is rotated around the rotation shafts 231b to 233b in a direction (rear) in which 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 backward from the state shown in FIG. 15 by approximately 90 degrees (until 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 thus rotated, 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 is in contact with 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 downward 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 ny latch 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 bracket member 230 is attached in a state in which the upper surface of the bracket member 230 is close to the lower surface of the top plate 5 c of the housing 5.

  Next, as shown in FIG. 19, the case caulking member 240 is inserted and attached to the caulking attachment portions 235 and 235 of the bracket member 230 from the right side. In the present embodiment, the lower caulking mounting portion 235 has a case caulking member 240 ′ (dummy case) that does not have the locking portion 242 (locking claw 242a) in the case caulking member 240 described above. A caulking member is attached. When the case caulking members 240 and 240 ′ are attached to the caulking attachment portions 235 and 235, the tip end portions (left end portions) of the case caulking members 240 and 240 ′ protrude to the left from the left side wall of the bracket member 230, and the case caulking The tip portions of the members 240 and 240 ′ cover and hide the heads of the mounting screws inserted into 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 by the screw cover 215 as described above, but the front side of the case caulking member 240 'covers the front side. It is like that.

  Since the front end portions (left end portions) of the case caulking members 240 and 240 ′ protrude 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 it is rotated to the state (the state shown in FIG. 17), the lower surfaces of the case caulking members 240 and 240 ′ are in contact with the inner surfaces of the base side engaging portions 211 and 212 of the left base member 210 and are supported by the bracket member 230. (The lower surface of the case caulking member 240 ′ is in contact with the inner surface of the screw cover 215). That is, the bracket member 230 is restricted from dropping by the case caulking members 240 and 240 ′.

After the case caulking members 240 and 240 ′ are attached to the bracket member 230, as shown in FIG. 20, the board case 120 in which the main control board 110 is accommodated inside the case is attached to the bracket member 230. The substrate case 120 is attached by inserting the case attachment protrusions 129 and 129 (see FIG. 3) provided on the right side of the substrate case 120 into the case attachment 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 left side portion of the substrate case 120 with the bracket member 230 and then engaging the right side portion thereof. 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 attached to the caulking attachment portion 235 are disposed inside the cover portion 135 of the substrate case 120, and the locking claws 242a are disposed on the substrate. 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 attaching portion 125 are broken to release the locked state with the case caulking member 240. The substrate case 120 is locked by the case locking claw 234 of the bracket member 230.

  Next, as illustrated in FIG. 21, the setting change device 250 is attached to the lower right portion (a position below the ny latch attachment portion 237) in the bracket member 230. The setting change device 250 is attached by engaging a mounting member 256 (see FIG. 12) formed on the upper surface of the setting change device 250 with the bracket member 230, and then Nylatch (registered trademark) provided on the setting change device 250. 257 is used to fix the setting change / change device 250 to the bracket member 230. 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, 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 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 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 electrical connectors 112 and 113 (see FIG. 3) of the main control board 110 housed in the board case 120, respectively. Then, a cover caulking member 138 (see FIG. 3) is attached to the substrate case 120 (case lid 131), and the connector cover 145 is mounted on the substrate 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 claw of the cover caulking member 138 is inserted into the locking groove in the connector cover 145. The 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 to release the locking state with the cover caulking member 138. The cable harnesses K2 and K3 connected to the main control board 110 are 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 latched and held by H.261.

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 (back plate 5e) with attachment screws so as to be rotatable in the front-rear direction. ing. For this reason, 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 substrate case 120 and the back surface of the main control board 110 accommodated in the case are illegal. It is possible to confirm whether or not an act is being performed. The bracket member 230 is formed with a cable receiving portion 236, 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 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. Therefore, the routing of these cable harnesses is concentrated on the hinge side of the front door 2. For this reason, conventionally, it has been difficult for these cable harnesses to obstruct the bracket member to be largely rotated. However, according to the board case mounting mechanism 200 having the above configuration, since the cable receiving portion 236 is provided in the bracket member 230, when the bracket member 230 is rotated, the cable harness is received in the cable receiving portion 236. Accordingly, the bracket member 230 can be largely rotated to a position close to the left side plate 5a of the housing 5 (nearly 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 and slides them 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. Then, the bracket member 230 is rotated by 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 around the rotation shafts 231b to 233b. Is attached in a state in which downward movement is restricted. The conventional shaft mounting structure in which the bracket member is hooked from top to bottom as in the prior art has 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 in which the upper surface of the bracket member 230 is close to the lower surface of the top plate 5 c of the housing 5. Therefore, the bracket member 230 and the substrate case 120 can be disposed in the housing 5 without causing a dead space between the top plate 5 c and the bracket member 230.

  The front end portions (left end portions) of the case caulking members 240 and 240 ′ attached to the bracket member 230 protrude leftward from the left side wall of the bracket member 230, and the front end portions of the case caulking members 240 and 240 ′ 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 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. Unauthorized removal can be prevented.

  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 side portion thereof. For this reason, 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-open front door 2 is largely opened. Accordingly, it is possible to prevent an act of illegally attaching and detaching the substrate case 120.

  The setting change device 250 is attached to the bracket member 230 together with the substrate case 120. Therefore, the setting change device 250 can be disposed near the main control board 110 in the board case 120, and the cable harness K1 that connects the main control board 110 and the setting change device 250 can be easily routed. In addition, the setting change 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 change device 250 can be operated to change the set value by slightly opening the right-open front door 2.

  Next, the change aspect of the said embodiment is demonstrated. The left base member 210 and the connector cover 145 described above may be modified like the left base member 310 and the connector cover 345 shown in FIGS. Note that the same reference numerals as in the above embodiment are assigned to the same components as those of the left base member 210 and the connector cover 145 described above, and the description of the components is omitted. As shown in FIGS. 24 and 25, groove portions 311 and 312 extending in the left-right direction are formed on the left side of the upper and lower screw insertion holes 211a and 212a on the front surface of the left base member 310, respectively.

  As shown in FIGS. 26 and 27, the connector cover 345 is formed in a shape extending leftward from the connector cover 145 described above, and screw covering portions 345a and 345b extending downward are vertically arranged at the left end portion thereof. Two are formed. When the connector cover 345 is attached to the board case 120 (the case lid 131), the cover caulking member 138 attached to the caulking attachment portion 139 of the case lid 131 is disposed inside the connector cover 345, and the cover caulking member 138 is engaged. A pawl is inserted into a 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 to release the locked state with the cover caulking member 138 (see FIG. 28). ).

  As shown in FIGS. 29 and 30, screw cover portions 345a and 345b of the connector cover 345 attached to the board case 120 are heads of attachment screws inserted into the screw insertion holes 211a and 212a of the left base member 310, respectively. Cover and hide. Note that 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 covered with the screw covering portion 345b of the connector cover 345. It is like that.

  Even when the connector cover 345 is attached in this manner, the bracket member 230 can be rotated in the front-rear direction with respect to the left base member 310 as shown in FIGS. 31 and 32. In order to make this possible, grooves 311 and 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 cover portions 345 a and 345 b of the connector cover 345 are fitted into the groove portions 311 and 312 of the left base member 310. Thus, the screw covering portions 345a and 345b interfere (collision) with the left base member 310 so as not to 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 can be 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. Unauthorized removal can be prevented. Further, since the groove portions 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.

  Further, as shown in FIG. 33, the setting change device 250 described above is not attached to the bracket member 230, but is rotated with the rotation shafts 231 b to 233 b (engagement with the left base member 210) as the rotation center of the bracket member 230. May be provided on the upper part of the left side plate 5a of the housing 5, which is in the vicinity of the portion). Alternatively, as illustrated in FIG. 34, a setting change device 250 may be provided on the upper portion of the back plate 5 e of the housing 5. By arranging the setting change device 250 in the vicinity of the rotation center of the bracket member 230 as described above, the cable harness for connecting the main control board 110 attached to the bracket 230 and the setting change device 250 can be easily routed. It 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. In this configuration, the bracket 210 is engaged with the member 210 (310). The bracket member 230 is formed with a shaft insertion hole that opens downward, and the left base member 210 (310) is formed with a pivot shaft that extends upward. Also good. 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 left base member 210 is configured such that the screw cover 215 is inserted only in the middle base side engaging portion 212 and covers the screw insertion hole 212a in the middle base side engaging portion 212. A screw cover 215 may also be inserted into the upper base side engaging portion 211 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. Thus, if it is set as the structure which covers both the screw penetration holes 211a and 212a using the two screw covers 215, the unauthorized access to the attachment screw attached to these penetration holes can be prevented further. Moreover, it is good also as a structure which covers both the screw penetration holes 211a and 212a integrally 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, but includes either one of the setting change key cylinder 251 and the setting change switch 252. Any configuration can be used. In that case, what is necessary is just to provide the other side separately from the setting change apparatus 250 in other places, such as the rear surface of the front door 2. FIG. In the above-described embodiment, the display unit 116 that displays the set value of the slot machine 1 (such as the winning probability of the game player) is provided on the main control board 110, but this display unit is not displayed on the main control board 110. Alternatively, it may be provided independently in the vicinity of the setting change device 250, the rear surface of the front door 2, or the like. 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 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-described embodiment, the attachment mechanism of the substrate case 120 that accommodates the main control board 110 has been described. However, the substrate case that accommodates the sub control board that performs various effect controls also has the same configuration as the case attachment mechanism 200. You may make it attach with 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, but Niflatch (registered trademark), a lever clip, or the like may be used instead.

  In the above-described embodiment, as an example of a gaming machine to which the present invention is applied, a slot machine (rotating-type gaming machine) that uses a gaming medal is illustrated and described. However, the present invention is not limited to this. The same effect can be obtained by applying the same to other game machines such as pachinko machines, revolving game machines using game balls, sparrow ball game machines, and arrange ball machines.
