As shown in FIG. 11, the substrate 60 is accommodated in the internal space 65 </ b> A of the substrate case 65 partitioned by the first case body 91 and the second case body 92.
The first substrate 61 and the second substrate 62 (see FIG. 6), and the third substrate 63 and the fourth substrate 64 are arranged in a state spaced from each other in the thickness direction Z. The first board connecting connector 81 of the third board 63 and the third board connecting connector 78 of the first board 61 are fitted together. As a result, the third substrate 63 and the first substrate 61 are electrically and mechanically connected.

  As described above, the first connector support part 136 of the first case body 91 presses the third board connecting connector 78 of the first board 61 from the Z1 direction side, and the third connector support part of the second case body 92 is pressed. 165 presses the first board connecting connector 81 of the third board 63 from the Z2 direction side. Therefore, the third board connection connector 78 and the first board connection connector 81 are supported in a state where movement in the thickness direction Z is restricted by the first connector support portion 136 and the third connector support portion 165. Thereby, the reliability of electrical and mechanical connection between the third board connecting connector 78 and the first board connecting connector 81 is improved.

  As described above, the second connector support portion 137 of the first case body 91 presses the fourth substrate connection connector 79 of the first substrate 61 from the Z1 direction side, and the fourth connector support portion of the second case body 92 is pressed. 166 presses the first board connecting connector 86 of the fourth board 64 from the Z2 direction side. Therefore, the fourth board connecting connector 79 and the first board connecting connector 86 are supported by the second connector support portion 137 and the fourth connector support portion 166 in a state in which movement in the thickness direction Z is restricted. . Thereby, the reliability of electrical and mechanical connection between the fourth board connecting connector 79 and the first board connecting connector 86 is improved.

  Each of the pair of projecting pieces 152 is inserted into the engagement hole 175A from the Z1 direction and hooked on the pair of hook portions 175. Each of the pair of first lock engaging portions 176 is engaged with each of the first engaged holes 154 </ b> B of the pair of first lock engaged portions 154. The second lock engaging portion 177 is engaged with the second engaged hole 155A of the second lock engaged portion 155 (see FIG. 10).

  The battery 85A housed in the battery holder 85 is pressed from the Z2 direction side by the battery support portion 164 of the second case body 92. Therefore, the movement of the battery 85 </ b> A in the thickness direction Z is restricted by the battery support portion 164 and the battery holder 85. Thereby, it can prevent that battery 85A remove | deviates from the battery holder 85 unexpectedly. Therefore, the timing of the RTC that is a part of the electronic component D is not unexpectedly reset.

  As shown in FIG. 12A, the operating means 84 is accommodated in the space 98 </ b> A of the switch accommodating portion 98. A space 98A of the switch housing portion 98 is partitioned from the Z2 direction side by the surface 63D of the third substrate 63 on the Z1 direction side. The hole 100 of the bottom wall 99 faces the switch region A1 of the surface 63D on the Z1 direction side of the third substrate 63 in the thickness direction Z. As described above, the wall portion 101 protrudes toward the Z2 direction. Therefore, in a state where the third substrate 63 is attached to the first case body 91, the wall portion 101 is a rectangular tube member that protrudes from the bottom wall 99 of the first case body 91 toward the third substrate 63, Surrounding means 84 and space 98A. As described above, in the substrate unit 3, the space 98 </ b> A of the switch housing portion 98 constitutes a space between the hole portion 100 and the switch region A <b> 1 of the surface 63 </ b> D of the third substrate 63.

A portion excluding the space 98 </ b> A in the space closer to the Z <b> 1 direction than the third substrate 63 in the internal space 65 </ b> A of the substrate case 65 is defined as a space 185. The space 98A and the space 185 are partitioned by the wall portion 101 (particularly, the first wall portion 101A on the X1 direction side and the second wall portion 101B on the Y1 direction side).
The operating means 84 mounted on the surface 63D on the Z1 direction side of the third substrate 63 faces the bottom wall 99 of the first case body 91 in the thickness direction Z. That is, the bottom wall 99 is a part where the operation means 84 faces the first case body 91.

  The operating means 84 is exposed to the outside of the substrate case 65 through the hole 100. Therefore, for example, when resetting the time measured by the RTC of the electronic component D, the operation means 84 can be operated by causing a rod-shaped jig to enter from the outside of the substrate case 65 through the hole 100. That is, the hole 100 is an operation hole. The hole 100 faces the switch area A1 of the third substrate 63.

For example, in a state where the board unit 3 is attached to the gaming machine 1 (see FIG. 2), a fraudulent jig (foreign matter) is caused to enter the internal space 65A of the board case 65, whereby the third board 63 is moved. It is conceivable to carry out an illegal act on the substrate 60 including it.
However, in this embodiment, the wall part 101 surrounding the operating means 84 and the space 98A is provided. Therefore, even when the fraudulent jig is inserted into the space 98A of the switch housing portion 98 from the outside through the hole 100 in the state in which the substrate unit 3 is attached, the portion excluding the space 98A of the internal space 65A of the substrate case 65 The wall portion 101 prevents the unauthorized jig from entering the space 185. Thereby, an illegal act on the substrate 60 including the third substrate 63 can be prevented.

Further, the tip 101 </ b> C on the Z <b> 2 direction side of the wall portion 101 is in contact with the surface 63 </ b> D on the Z <b> 1 direction side of the third substrate 63. Therefore, the entry of the fraudulent jig into the space 185 of the substrate case 65 can be prevented more reliably.
Next, as shown in FIG. 12B, a case where the operating means 84 is not mounted on the third substrate 63 will be considered. In this case, a substrate case 65 is used to accommodate the substrate 60. In this case, the hole 100 faces the switch area A <b> 1 of the third substrate 63 in a state where the substrate 60 is accommodated in the substrate case 65. Compared with the case where the operating means 84 is accommodated in the space 98A, the fraudulent jig can be easily entered into the space 98A of the switch accommodating portion 98. However, even if the fraudulent jig is inserted into the space 98A of the switch housing portion 98 through the hole 100 from the outside, the fraudulent jig to the space 185 that is a portion excluding the space 98A in the internal space 65A of the substrate case 65 is used. Is prevented by the wall portion 101. Thereby, an illegal act on the third substrate 63 can be prevented.

  As described above, since the illegal operation can be prevented both when the operation means 84 is mounted on the third substrate 63 and when the operation means 84 is not mounted, the third substrate 63 on which the operation means 84 is not mounted is attached. The substrate case 65 can be shared between the case of using and the case of using the third substrate 63 on which the operation means 84 is mounted. Thereby, cost can be reduced and the gaming machine 1 can be manufactured efficiently.

Therefore, the fixation of the first substrate 61 to the first case body 91 is released, and the fixation of the second substrate 62 to the first case body 91 is also released.

  Next, from this state, each member is removed from the first case body 91 by a procedure reverse to the assembly process of the substrate unit 3 described above. Specifically, first, the fourth screw 74 and the sixth screw 76 are removed. Next, the engagement between the first lock engaging portion 176 of the second case body 92 and the first engaged hole 154B of the first lock engaged portion 154 of the first case body 91 is released. Further, the engagement between the second lock engaging portion 177 of the second case body 92 and the second engaged hole 155A (see FIG. 2) of the second lock engaged portion 155 of the first case body 91 is released. . As a result, the second case body 92 is removed from the first case body 91.

  Next, as shown in FIG. 8, the third screw 73 and the fifth screw 75 are removed, and the fixation of the third substrate 63 and the fourth substrate 64 to the first case body 91 is released. As described above, since the first substrate 61 and the second substrate 62 are not fixed to the first case body 91 in the first step of the dismantling operation, the substrates 61, 62, 63, and 64 are attached to the substrate case 65. It can be removed outside.

  The substrates 61, 62, 63 and 64 are removed, and the removed substrates 61, 62, 63 and 64 are moved to another work place while the connection between the substrates 61, 62, 63 and 64 is maintained. At the work place, the connection between the boards 61, 62, 63 and 64 is released by releasing the mechanical connection between the connectors 77, 78, 79, 80, 81, 82, 86 and 87. Can do.

  Next, consider a case where the fixing of the first substrate 61 and the second substrate 62 to the first case body 91 is not released in the first step of the dismantling operation. In this case, after the fixation of the third substrate 63 and the fourth substrate 64 to the first case body 91 is released, the group of the third substrate 63 and the fourth substrate 64 is combined with the first substrate 61 and the second substrate 62 (FIG. 7). (Refer to). This separation work needs to be performed in a state in which the substrates 61, 62, 63 and 64 are attached to the substrate case 65. In this case, it is difficult to detach the substrates 61, 62, 63 and 64 from each other, and as a result of performing such a difficult operation, the connectors 77, 78, 79, 80, 81, 82, 86 and 87 are damaged. There is a risk of inviting.

However, in this embodiment, the fixation of the first substrate 61 and the second substrate 62 to the first case body 91 is released in the first step of the disassembly work. Therefore, it is possible to move to another work place outside the substrate case 65 and perform a detaching operation for releasing the connection between the substrates 61, 62, 63 and 64.
Thereby, the work of disassembling the substrate unit 3 is facilitated. Therefore, it is possible to prevent damage to the connectors 77, 78, 79, 80, 81, 82, 86, and 87 that connect the substrates 61, 62, 63, and 64 during the work.

Next, a modified example of the present invention will be described.
FIG. 13 is a diagram showing a modification of the present invention. In FIG. 13, the same members as those described above are denoted by the same reference numerals, and the description thereof is omitted.
The switch accommodating part 98 of the modification includes a cylindrical third wall part 178 instead of the first wall part 101A on the X1 direction side and the second wall part 101B on the Y2 direction side. The third wall portion 178 protrudes from the bottom wall 99 to the Z2 side and surrounds the edge of the hole portion 100. The third wall portion 178 also surrounds the end portion 84A on the Z2 direction side of the operation means 84.

Therefore, the entry of the fraudulent jig into the space 98A near the hole 100 can be suppressed, so that the fraudulent jig can be more reliably prevented from entering the space 185 of the substrate case 65.
As mentioned above, although one Embodiment of this invention was described, this invention can also be implemented with another form.

For example, the wall portion 101 does not necessarily have to be in contact with the surface 63D on the Z2 direction side of the third substrate 63, and only needs to protrude to the Z2 direction side to the extent that entry of a fraudulent jig can be prevented.
Further, a plurality of predetermined operation means 84 may be provided. In this case, the first case body 91 may have a plurality of switch accommodating portions 98 corresponding to the respective operation means 84, and the first case body 91 is a switch that accommodates the plurality of operation means 84 collectively. You may have the accommodating part 98. FIG. In any case, the wall portion 101 of the switch accommodating portion 98 surrounds the operation means 84 individually or collectively, and the wall portion 101 prevents the unauthorized tool from entering the space 185 of the substrate case 65. it can.

In addition, the case where the substrate 60 accommodated in the substrate case 65 is an effect control substrate or a liquid crystal control substrate has been described as an example, but the substrate 60 may be a main control substrate or a payout control substrate.
Furthermore, the board 60 can be a board other than the control board (for example, a relay board or a power board). That is, the board 60 includes a control board such as an effect control board, a liquid crystal display control board, a main control board, and a payout board, as well as a power supply board, a relay board, and the like, and is not intended to limit the application.

  When the board 60 is a power supply board, a RAM clear switch (not shown) for clearing data of at least one of the main control board, the liquid crystal control board and the payout control board to zero is adopted as the operation means 84. Can do. The RAM clear signal is turned on when an operator (for example, an employee of an amusement shop) has turned on the RAM clear switch. If the RAM clear switch is not operated, the RAM clear signal returns to the off state (high level). When the RAM clear signal is turned on and the power is turned on, the data stored in the RAM and the data stored in the payout control board RAM are each cleared to zero. On the other hand, if the RAM clear signal is turned off and the power is turned on, the RAM data is not cleared to zero.

The operation means 84 is not limited to a form such as a dip switch or a rotary switch in addition to a push button switch.
Further, although the RTC switch and the RAM clear switch have been described as examples of the operation means 84, the present invention can also be applied to operation means for uses other than the RTC switch and the RAM clear switch.
In addition, various design changes can be made within the scope of matters described in the claims.
