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 a prize ball and a safe ball 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 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. Hitherto, as a measure 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 has been proposed, and as an example of the former, Japanese Utility Model Application Laid-Open No. 60-13174. ,
Japanese Utility Model Application Laid-Open No. 2-113576 discloses an example of the latter.

[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 invented in order to protect the 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.

DISCLOSURE OF THE INVENTION The present invention has been made based on the above-mentioned object, and in particular, the present invention is to form a base plate constituting a base of a mechanism frame by using a conductive synthetic resin as a material. On the other hand, a first chamber that forms a ball passage for guiding a prize ball and a safe ball and a second chamber that stores mechanical components are separately provided on both sides of the base plate as an electric shielding plate,
Further, a third chamber for accommodating a lead wire is provided on one surface of the second chamber, and the second chamber is interposed between the first chamber and the first chamber to prevent static electricity generated in the ball passage from affecting the third chamber. It is in. More specifically, the present invention relates to a mechanism frame that is rotatably hinged and attached to one side edge of a rear surface of a mechanism plate provided behind a front frame, and a base of the mechanism frame. The board is formed from a conductive synthetic resin material, and on one side of the prize ball system, prize ball release passages, ball removal passages and other prize ball system equipment, and safe ball passages and safe ball detectors such as safe ball detectors. A first chamber for storing various system equipment is formed, and a second chamber for storing a mechanical component for controlling opening and closing movement of the prize ball device is formed on the other surface, while the prize ball device is formed on one surface of the second chamber. A third chamber is formed to accommodate the lead wires to be connected to the mechanical parts, the lead wire for the prize ball emission counter, the safe ball counter, and the detector for detecting the standby ball. It is to provide a pachinko machine characterized by having a structure.

[0005]

According to the present invention, a base plate serving as an electric shielding plate is interposed between the first chamber serving as a source of static electricity, that is, the third chamber accommodating a lead wire. In addition, since the second chamber accommodating the mechanical components is interposed and spaced apart from each other, the lead wire can be protected from the influence of static electricity. Next, an embodiment illustrating the present invention will be described in detail.
