Description of the Related Art In recent years, gaming machines such as pachinko machines and slot machines have become the mainstream to control a prize device, a display device, and the like provided on a game board to enhance the interest of the game. The control of the winning device and the display device is performed by a logic control circuit board on which a large number of electronic components such as ICs and LSIs are disposed or a control circuit board having a microcomputer. The control circuit board includes a box base and a box cover. Encased in a box box.

[0003] By enclosing the control circuit board with this board box, illegal acts such as contact with the control circuit board can be prevented. However, the wiring connected to the connector of the control circuit board is provided in the board box. A lead-out port for leading out the cable must be formed, and the lead-out port can contact the control circuit board wrapped in the board box. Therefore, it is necessary to sufficiently prevent illegal acts on the control circuit board. Could not.

Therefore, a method has been proposed in which a partition plate (side wall plate) that closes the outlet is used to prevent contact with the control circuit board. In this method, a partition plate is erected at a position inside the connector position on the control circuit board,
This prevents contact with electronic components and the like mounted inside the control circuit board from the connector position, and also allows the wiring cable to be connected to the connector on the control circuit board via the outlet.

When a control circuit board on which such a partition plate is provided is stored in a board box, the partition plate and a box cover that covers the box base are connected by screws or the like. In this case, a through hole is formed in the box cover, and a screw hole into which a screw member such as a wood screw is screwed is formed in the partition plate, and the through hole and the screw hole face each other.
