DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a mechanism frame for storing mechanical parts for controlling and operating a prize ball ejection and a safe ball detection of a pachinko machine.

[0002]

2. Description of the Related Art As is well known, a pachinko machine counts a ball launched from a hit ball launching device as a safe ball when the ball hits a safe ball receptacle provided on a game board, and a predetermined number of prize balls. Is released to the player, while the ball that did not become a safe ball is collected as an out ball, and the game is established in relation to putting in and out the ball, but the safe ball counting and prize ball releasing operations are This is done by using mechanical parts provided behind the game board, specifically, on the back of the mechanism board that houses the game board. At present, some of these mechanical parts are directly mounted on the back of the mechanical plate. However, mechanical parts are unitized for manufacturing / assembly, maintenance and inspection, etc. At times, a method of assembling a plurality of types of parts at a time has been implemented. As one method of unitizing the mechanical parts, a frame body in which the parts are assembled from a synthetic resin as a material, that is, a mechanical frame body is formed, a predetermined ball passage is formed at the time of manufacturing the frame body, and simultaneously a prize ball device or a safe ball is formed. 2. Description of the Related Art A mounting portion for incorporating a detector or the like is integrally formed.
For this reason, the mounting position of the component is specified, and the relationship between the components is accurately determined, so that it is possible to assemble with high accuracy and to assemble easily and quickly. However, since it is manufactured using synthetic resin as a material, when a pachinko ball falls through a ball passage provided inside, static electricity is generated, which is charged to the mechanism frame and detected through lead wires etc. wired inside this There is a problem that adversely affects equipment. Conventionally, as a method for solving these problems, a method of providing a ground, or a method of avoiding the problem by using a conductive synthetic resin as a material, and the like have been proposed. ,
There is a proposal in Japanese Utility Model Laid-Open No. 2-13576 and the like, and as an example of the latter, Japanese Utility Model Publication No. 2-44793.

[0003]

However, the above-mentioned conventional solutions are not yet sufficient, and there is a danger that static electricity will act on the lead wires wired inside the mechanism frame, causing erroneous counting or erroneous operation. There was a problem that could not be completely avoided. The present invention has been developed to protect lead wires from static electricity charged on a mechanism frame formed of such a synthetic resin as a material and to prevent generation of noise.
