In Japanese Patent Publication No. -1754, a circuit box is constituted by a detachable cover case and a base, and the cover case or the base is pivotally connected to the back side of the pachinko machine main body so that one side can approach and separate. The base is provided with a plurality of mounting seats capable of fastening a plurality of types of circuit boards having different sizes, a notch is formed on one side of the cover case, and connection terminals are provided at positions corresponding to the notches on the circuit board. Is provided. Furthermore, real fairness 3
Japanese Patent Application Laid-Open No. 15089 proposes a structure in which a mechanism plate corresponding to a substrate housing member that houses a circuit board has a structure avoiding the mechanism plate.

[0003]

However, for example, in Japanese Utility Model Publication No. 3-85080 and Japanese Utility Model Publication No. 4-1754, the circuit box is not mounted on the mechanism frame set member. Therefore, the wiring may be erroneously hooked and broken by the operation on the back side of the pachinko machine during the operation of the game store. In addition, since the protection of the connector is not sufficient, an electrical trouble may occur. On the other hand, in Japanese Utility Model Publication No. 3-15089, since the substrate box and the back mechanism of the variable winning device are not protected, there is a possibility that an electric or mechanical trouble due to dust or dust may occur. There is. In addition, since the board box is attached and detached after opening the mechanism plate,
Poor workability. Therefore, an object of the present invention is to provide a pachinko machine that has good workability and can visually recognize each member to prevent a fraudulent game.
