Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a board box which is mounted on a winning ball collecting cover arranged on the back surface of a game board and which houses a control circuit board for controlling a game operation.

[0002]

2. Description of the Related Art Conventionally, a window is provided on a mechanism plate mounted on the back side of a pachinko machine so as to be openable and closable in a position corresponding to a winning ball collecting cover. Then, on the surface of the winning ball collecting cover, a winning device protective cover that covers the rear part of the winning device by protruding from the window and a board box are attached to the outside thereof. By the way, recently, the board box tends to become large in accordance with the contents of the game, so that the board box protrudes from the window to the outside and overlaps with the outer edge of the mechanism plate to prevent the mechanism plate from being opened and closed. . Therefore, for example, as disclosed in Japanese Patent Application Laid-Open No. 3-109089, a supporting plate is fixed to the surface of the winning ball collecting cover, and the inner side surface of the substrate box is pivotally supported on the upper end of the supporting plate. By rotating the substrate box about the fulcrum and raising it sideways, the overlap with the mechanism plate is released and the mechanism plate can be opened and closed.

[0003]

However, when the winning device protection cover is large, even if it is necessary to open the mechanism plate to raise the substrate box sideways, the portion above the pivotal support of the substrate box is the winning device protection cover. However, there is a problem in that the substrate box cannot be completely raised due to the use of the substrate, and as a result, the mechanism plate cannot be opened. Therefore, the present invention has been made to solve the above-described problem, and the mechanism plate can be opened even when a large prize winning device protection cover is attached so that the substrate box is erected sideways while rotating horizontally. It is an object of the present invention to provide a mounting structure for a board box in a pachinko machine capable of performing the above.

[0004]

In order to achieve the above object, the mounting structure of the board box in the pachinko machine of the present invention electrically controls the game operation on the winning ball collecting cover arranged on the back surface of the game board. In a pachinko machine that is equipped with a board box that houses the control circuit board,
A butterfly is attached to the surface of the winning ball collecting cover so that one side of the rotating plate having a predetermined width is attached to the board box and the other side of the rotating plate is erected sideways while rotating the board box in the horizontal direction. I wore it.

[0005]

With the lateral rotation of the substrate box, the rotating plate is folded back around the hinged portion on the surface of the winning ball collecting cover, and the substrate box is erected sideways. This allows the mechanism plate to be opened and closed. Moreover, since the board box is erected within the lateral width range at the mounting position, it cannot be held by the winning device protective cover.
