[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine having a game board storage member for storing a game board, and having a plurality of control devices on the back side of the game board storage member.

[0002]

2. Description of the Related Art Generally, a game machine such as a pachinko game machine is provided with a game board storage member for storing a game board, and a ball storage section and a ball flow path are formed on the back of the game board storage member. Various devices (for example, storage tanks, outlet gutters, ball punching devices,
A back mechanism panel in which a discharge device, a flow-down device, etc.) are assembled to the mounting base member is disposed. In recent years, in this type of gaming machine, there has been a tendency that a plurality of control devices classified by function are provided over the entire rear surface side of the rear mechanism panel.

[0003]

However, in the above-mentioned conventional gaming machine, static electricity may be charged on the ball channel and the sphere flowing through the ball channel, and the static electricity may be discharged in the ball channel. Since it was not possible, static electricity was sometimes accumulated in the spherical channel and the sphere flowing through the spherical channel. Then, there is a possibility that each control device may malfunction due to the influence of such static electricity.

The present invention has been made in view of the above circumstances, and has as its object to provide a gaming machine capable of preventing a malfunction of a control device due to noise such as static electricity.
