Conversely, when rotating the sealing screw 11 and the spare sealing screw 111 in the anti-screw direction,
An engagement groove for causing the screwdriver to run idle, that is, a so-called one-way cross groove may be provided. As a result, since the sealing screw 11 cannot be rotated in the anti-screw direction, the act of removing the sealing screw 11 inserted into the nut 12 can be prevented.

In this embodiment, the sealing unit 1 and the substrate box 40 are formed as separate members in the substrate box 40. However, the sealing method is not limited to this, and each of the box body and the box lid of the substrate box and each unit member of the sealing unit may be integrally formed.

Further, in this embodiment, the spare screw locking members 34 numbered K from “2” to “4” are provided on the outer peripheral side surface of each sealing member 31. However, the position of the spare screw locking member 34 is not limited to this, and the spare screw locking member 3 with the number K of “5” is attached.
As shown in FIG. 4, the spare sealing member held in the spare screw holding hole of the spare screw holding member may be locked by being provided on the side surface of the plate 32a of the mounting member 32.

In this embodiment, the connecting members 33 are fixed to the sealing members 31 one by one. But,
The number of such connecting members 33 is not necessarily limited to this, and the mounting member 32 and one sealing member 31 may be connected by a plurality of connecting members. With this configuration, in order to open the substrate box, it is necessary to cut a plurality of portions of the sealing unit, which makes it difficult to conceal fraud.

In this embodiment, the rib member 36 is provided only on the unit member 30. However, the arrangement position of the rib member is not necessarily limited to this, for example,
Instead of the built-up portion 26 provided on the unit member 20, a plurality of rib members may be provided adjacent to both side portions of each connecting member 23.

According to the first aspect of the present invention, since the first sealing member and the second sealing member are connected by the connecting sealing member, the circuit board is provided in the gaming machine substrate box. Can be reliably sealed. Therefore, there is an effect that it is possible to remove the ROM in which the control information relating to the game content is stored from the control circuit board and replace the ROM, thereby preventing an illegal act of changing the game content.

The sealed game machine substrate box can be opened by cutting the connecting member, but since the cutting member is provided adjacent to the cutting preventing member, it cannot be cut easily. I have. Therefore, there is an effect that it is possible to prevent the illegal act of opening the gaming machine substrate box by cutting the connecting member.

On the other hand, when the cutting prevention member disposed adjacent to the joining member is cut and removed by a cutting tool or the like, the joining member can be cut. In this case, if the joining member is further cut after the cutting prevention member is cut, the gaming machine substrate box can be opened, but in such a case, the cutting traces appear at a plurality of locations of the gaming machine substrate box sealing device. Is left. Therefore, in order to conceal such misconduct, it is necessary to apply an adhesive or the like to each of the cut portions and rejoin each of the plurality of cut portions. It is not easy to hide traces of. Therefore, when the board box for a gaming machine is opened, it is possible to reliably leave traces of it, so that fraudulent acts can be detected early and the fraudulent acts can be suppressed. There is.

According to the board box sealing device for a game machine according to the second aspect, similarly to the board box sealing device for a game machine according to the first aspect, it is possible to prevent a fraudulent act of changing game contents. effective.

When opening the sealed game machine substrate box, all of the plurality of connecting members for connecting one of the box base or the box cover and the first sealing member must be cut by a cutting tool or the like. Must. Therefore, in order to conceal such misconduct, it is necessary to apply an adhesive or the like to each of the cut portions of all the connecting members and rejoin each of the plurality of cut portions. Joining and hiding traces of cutting is not easy. Therefore, when the board box for a gaming machine is opened, it is possible to reliably leave traces of the box, so that fraudulent acts can be detected early,
There is an effect that such misconduct can be suppressed.
