Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a static electricity removing device for a pachinko machine.

[0002]

2. Description of the Related Art In a pachinko machine, static electricity is generated due to contact friction when a pachinko ball shot by a player rolls in a game area via an outer rail, and the static electricity becomes noise in an electronic control unit. Because it has a bad effect
Various measures and countermeasures have been taken to remove accumulated static electricity. For example, in the pachinko machine of Japanese Patent No. 2822259, a flat plate of a conductive elastic body is attached to a guide body attached to an outer rail that guides a game ball into the game area, and a conductive elastic body is attached to the outer periphery of the inner rail. By mounting the anti-tampering tool formed by the above, and by bringing the closed metal glass frame into contact with at least one of the flat plate and the conductive elastic body, the static electricity is guided to the grounding section through the glass frame. A configuration made is disclosed.

[0003]

In the method of removing static electricity described in the above-mentioned patent publication, since the guide body is provided with a flat plate of a conductive elastic body and the inner rail is provided with a tamper-proof device, the It can be said that the work for assembling the above parts is troublesome and the manufacturing cost is not always low. Further, in pachinko halls, the glass frame is often opened and closed for maintenance and management, and the conductive elastic body and the glass frame repeat contact / non-contact operation with the opening / closing operation,
There is a risk that the contact parts will be damaged.

An object of the present invention is to provide a static eliminator for a pachinko machine which can be easily implemented at low cost and has improved durability.

[0005]

In order to achieve the above object, the invention described in claim 1 is such that a guide rail for guiding a pachinko ball is annularly arranged on a conductive mounting frame fixed to an outer frame. In a pachinko machine in which the provided game board is detachably provided, the guide rail is provided so as to be electrically conductive to the mounting frame, and the static electricity accumulated in the guide rail is grounded through the mounting frame. It is characterized by being configured.

According to a second aspect of the present invention to achieve the same object, in the static eliminator for a pachinko machine according to the first aspect, the decorative member arranged outside the guide rail is provided with the rail. It is characterized in that a conductive member is provided which is in contact with both of the mounting frames.

According to a third aspect of the invention for achieving the same object, in the static electricity eliminator for a pachinko machine according to the first aspect, a conductive material that comes into contact with the guide rail at an appropriate position of the mounting frame is provided. An elastic piece is provided.

[0008]

The guide rail including the outer rail and the inner rail can be electrically connected to the mounting frame. Then, static electricity accumulated on those rails is guided to the mounting frame → power supply board → power supply cord (grounding section) and removed. As a result, the noise phenomenon of the electronic control unit due to static electricity does not occur.

The static electricity removing device in this pachinko machine can easily and surely remove the static electricity generated and accumulated due to the contact friction of the pachinko balls, etc., and is more durable than the conventional one. In addition, there is an advantage that it can be easily implemented at low cost.
