Is formed to be substantially equal to the width of the guide piece 58 to regulate the left and right positions of the circuit box 31, and the hook 58 a of the guide piece 58 is hooked on the hooking edge 93 a provided on the front edge of the guide shelf 93. The height position can be restricted by stopping.
In addition, a tubular receiving portion 94 corresponding to the guide boss 57 of the circuit box 31 is extended to the upper edge corner. Therefore, when the guide piece 58 of the circuit box 31 is placed on the guide shelf 93, the vertical position and the horizontal position of the circuit box 31 are determined by themselves, and if the circuit box 31 is pressed toward the game board 12 in this state, Since the first connector 48 and the second connector 65 are fitted together, and the guide boss 57 is fitted in the tubular receiving portion 94, the circuit box 31 can be mounted very easily at an appropriate position. In addition, during the mounting operation, the first connector 48 and the second connector 65 are not damaged by inadvertent movement of the circuit box 31.
At this time, the release lever 64 is pressed by the end of the second connector 65 and returns.

Next, the circuit box 3 having the above-described configuration will be described.
1 and the removal of the relay member 43 will be described.

For example, when inspecting whether or not unauthorized alteration has been performed, the front frame 2 of the pachinko machine 1 is opened and the back side of the game board 12 is viewed. Can be found through the see-through portion of the circuit box 31, that is, the observation port 51 of the shield member 46.

Further, the state of the paper seal to be passed over the lower case 45 and the upper case 44 is verified from the side of the circuit box 31 or the release lever 64 is rotated to rotate the first connector 48 and the second connector. If the circuit box 31 and the relay member 43 are separated by removing the connection with the circuit box 65 and the circuit box 31 is turned over, the sealed state can be checked even better.

Further, when the locking member 62 is rotated and the shield plate 59 is removed, the back surface of the circuit board 30 can be checked without disassembling the circuit box 31 through the transparent lower case 45. In addition, since the seal is stuck on the side wall portion of the upper case 44 from the lower case 45 of the cutout portion 59a provided in the shield plate 59, the seal is stuck, so even if the shield plate 59 is removed, the seal is broken. There is no. Further, in the present embodiment, since the edge piece 60 at the position where the paper seal is to be stuck is cut, the paper seal is not lifted by the edge piece 60 and the paper seal is not easily broken.

On the other hand, the mounting of the circuit box 31 may be performed in the reverse of the above. The guide piece 58 is placed on the guide shelf 93 of the relay member 43, and the circuit box 31 is pressed toward the relay terminal board 84 in this state. The first connector 48 and the second connector 65 may be connected, and the guide boss 57 and the tubular receiving portion 94 may be fitted. Since the locking edge 93a of the guide shelf 93 and the hook 58a of the guide piece 58 are locked, the circuit box 31 does not slide down.

Further, according to the present embodiment, the relay member 43
Can also be exchanged. That is, each wiring connector 86 ...
Then, when the attachment plate 85 is slid upward, the engagement between the mounting tongue piece 77 and the holding portion 76 is released, so that the relay member 43 can be removed from the base frame member 42. Therefore,
If the relay terminal board 84 is replaced in the case of a model change or the like, various wirings can be easily changed.

In the present invention, the game control circuit board 30 housed in the circuit box 31 and the main body control box 3
4 and the game board 12 are connected to the relay terminal board 8
4 and connected to the outside such as a power supply and a management computer, etc. The external relay board 95 for the main body provided at the upper corner of the rear plate 23 and the external relay terminal for games provided at the upper corner of the game board 12 It is connected via a section 96. Therefore,
Various signal lines and various electric devices can be separately removed without affecting each other.

Although the present invention has been described with reference to the embodiment shown in the drawings, the present invention is not limited to the above-described embodiment, and can be appropriately implemented unless the configuration described in the claims is changed.
