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

0002

[Prior Art] As is well known, in a pachinko machine, when a ball fired from a ball launcher flies into a safe ball socket provided on a game board, this ball is counted as a safe ball and a predetermined number of prize balls are awarded. The ball is released to the player, while balls that are not safe balls are collected as out balls, and the game is established based on the relationship between putting in and taking out balls. However, the counting of safe balls and the operation of releasing prize balls are This is done using mechanical parts provided behind the game board, specifically on the back of the mechanical board that houses the game board. Currently, some of these mechanical parts are attached directly to the back of the mechanism plate, but for reasons such as manufacturing assembly or maintenance and inspection, it is necessary to unitize the mechanical parts and assemble parts for each system in advance. Sometimes a method is used to assemble multiple types of parts at once. One method of unitizing these mechanical parts is to form a frame, that is, a mechanism frame, into which the parts are assembled using synthetic resin as a material. At the time of manufacturing the frame, a predetermined ball path is formed, and at the same time, a prize ball device and a safe ball are formed. A mounting portion into which a detector or the like is installed is formed integrally. As a result, the mounting positions of the parts can be specified and the relationships among the parts can be accurately determined, making it possible to assemble with high precision and to assemble easily and quickly. However, since it is manufactured using synthetic resin as a material, static electricity is generated when a pachinko ball falls through the ball passage provided inside, which is charged to the mechanism frame and detected through lead wires etc. wired inside the mechanism frame. There is a problem that adversely affects equipment. Conventionally, methods to solve these problems have been proposed, such as installing a ground or using conductive synthetic resin as a material. ,
Examples of the latter include proposals such as Japanese Utility Model Publication No. 2-44793.

0003

[Problems to be Solved by the Invention] However, the above-mentioned conventional solutions are still not sufficient, and there is a risk that static electricity may act on the lead wires wired inside the mechanism frame, causing erroneous counting or malfunction. , there was a problem that could not be completely avoided. The present invention was invented in order to protect the lead wires from static electricity that accumulates on the mechanism frame body molded from these synthetic resins and to prevent the generation of noise.

0004

[Means for Solving the Problems] The present invention has been made based on the above-mentioned objects, and in particular, the present invention is directed to molding a base plate constituting the foundation of a mechanism frame from a conductive synthetic resin material. On the other hand, this base plate is used as an electrical shielding plate, and on both sides thereof, a first chamber that forms a ball passage for guiding prize balls and safe balls, and a second chamber that stores mechanical parts are provided.
Further, a third chamber for accommodating the lead wire is provided on one side of the second chamber, and the second chamber is interposed between the second chamber and the first chamber to prevent static electricity generated in the bulb passage from affecting the third chamber. There is a particular thing. More specifically, the present invention provides a mechanism frame which is rotatably hinged and attached to one side edge of the rear surface of a mechanism plate provided behind a front frame, the base of the mechanism frame being attached. The board is made of conductive synthetic resin, and on one side is equipped with various equipment for the prize ball system such as a prize ball device, prize ball ejection passage, ball removal passage, safe ball passage, and safe ball detection such as a safe ball detector. A first chamber is formed to house various equipment of the system, and a second chamber is formed on the other side to house mechanical parts that control the opening/closing movement of the prize ball device. A third chamber is formed to house the lead wires connected to the mechanical parts, the counter for the number of prize balls released, the safe ball counter, and the lead wires for the detector that detects waiting balls.The mechanism frame is made up of three layers. To provide a pachinko machine characterized by a structure.

[0005]

[Operation] The present invention is constructed as described above, and a base plate serving as an electrical shielding plate is interposed between the first chamber, which is a source of static electricity, that is, the ball passage, and the third chamber, which accommodates the lead wire. In addition, since the second chamber housing the mechanical parts is interposed and separated from the second chamber, the lead wires can be protected from the influence of static electricity. Next, an illustrative embodiment of the invention will be described in detail.

The mechanism frame 7 is constructed around a substantially L-shaped base plate 8 placed in the center, and one side of the base plate 8 (
On the rear side when viewed from the pachinko machine body, there is a prize ball storage part 9 of a prize ball device that stores prize balls and releases them when a prize ball is awarded, and a frame part 12 that houses upper and lower stopper members 10, 11, etc. that control the release of prize balls. It is provided integrally to form a first chamber 13. On the other side, a frame 14 stands up along the entire circumference along the periphery, and is formed into a housing shape with one side open, and a second chamber in which the case 15 is housed so as to divide the interior into two, front and rear. 16 and a third chamber 17 are provided, the second chamber 16 contains driving parts 18 of the prize ball device, and the third chamber 17 contains lead wires 19 for the solenoid of the prize ball device, lead wires for the safe ball detector, etc. It is designed to accommodate each.

Effects of the Invention The present invention is constructed as described above, and the static electricity generated by the prize balls sent through the prize ball storage section of the mechanism frame, the prize ball discharge passage, etc. is discharged through the base plate, and the static electricity is discharged through the base plate. This prevents noise from being caused to the lead wires wired inside the mechanism frame, and the lead wires in the present invention are not connected to the mechanism parts or the prize ball discharge path, which is a source of static electricity. The structure is such that the second chamber containing the sensor is housed in a separate third chamber with the second chamber interposed between them, making it possible to more reliably protect against static electricity. This has the effect of effectively avoiding malfunctions.
