DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-and-ball game machine, and more particularly to a ball tank, a pay-out passage such as a tank rail, and a game ball for removing static electricity charged on a ground wire, and furthermore, from a ground wire. The present invention relates to a device that prevents electrostatic discharge and further enhances noise countermeasures.

[0002]

2. Description of the Related Art Conventionally, in a ball-and-ball game machine such as a pachinko machine, a back mechanism plate is detachably mounted on the back side of a front frame.
A ball tank and a tank rail extending therefrom are provided above the back mechanism plate, and game balls conveyed from game ball conveyance paths provided for each island structure of the pachinko hall are supplied to the ball tank. . A payout device for paying out game balls is provided on a side portion of the back mechanism plate, and a payout ball passage connected to the payout device is provided below the back mechanism plate. Therefore, when a game ball wins the prize means, the payout device is driven, a predetermined number of game balls are paid out as prize balls, and these paid out game balls pass through the payout ball passage from the upper plate discharge port. It is paid out to a saucer.

[0003] In addition, out balls and winning balls used for ball games are collected at the hole side through a game ball collection path, polished by a polishing device, and then returned to a ball tank via a game ball conveyance path. It is being supplied. By the way, since the game ball transport path, the ball tank, and the game ball payout passage connected to the ball tank are made of a synthetic resin insulator, static electricity generated when the game ball is polished by the polishing device is When a game ball is frictionally contacted or collides with the conveyance path or the game ball during the course of conveyance along the game ball conveyance path on the hole side, static electricity is generated, and the game ball is charged (so-called , Contact charging).

[0004] Furthermore, when the ball is supplied from the game ball transport path to the ball tank by dropping, when a plurality of game balls in the ball tank collide, static electricity is generated, and the static electricity may be charged on the game ball. Is high. This means that some of the static electricity generated in the game ball is transferred to the insulator passage when the game ball is made of metal, but moves along the passage of the insulator made of synthetic resin while colliding with the passage or the game ball. Although the static electricity is also charged in the path of the insulator, the game ball supplied to and stored in the ball tank tends to be charged with static electricity.

When these electrostatically charged game balls move from the ball tank to the tank rail or the ball passage in the dispensing device, they collide with or separate from each other or the ball passage, and the game ball is focused on the ball. Discharge occurs or electrostatic discharge occurs in the air. As a result, electromagnetic wave noise is generated due to the generation of a magnetic field, which adversely affects control signals of various control units that control game control, and the control units may stop operating or malfunction. Therefore, conventionally, a metal plate is provided in a part of a payout ball passage where a game ball such as a ball tank, a tank rail or the like collides during movement and static electricity is easily generated, so that the metal ball can be brought into contact with the game ball, and the inner frame is formed outside. A hinge fitting rotatably connected to the frame and its metal plate are connected by a ground line, so that static electricity charged on the game ball is grounded to the hinge fitting.

[0006]

As described above, a metal plate is provided in a part of a payout ball passage through which a game ball is easily contacted during movement, and static electricity charged on the game ball is discharged from the metal plate or the ground line. At this time, the hinge fittings of the inner frame are grounded to escape, but the hinge fittings are small and not a full-scale grounding plate, so that at present, a sufficient grounding effect is not obtained. Therefore, the noise of the electromagnetic waves generated by the electrostatic discharge of the moving game ball has an adverse effect on various control boards and the like that control the game control, which causes a problem that the game control is hindered. .

Therefore, it is possible to connect the other end of the ground wire to a ground circuit in place of the hinge fitting. However, the ground wire generally uses a normal connection cord whose conductor is simply covered with vinyl. In this case, there is a problem that an electrostatic discharge is generated in the air from the conductor of the ground line through the coating, and electromagnetic noise is generated similarly to the game ball.
In addition, noise due to static electricity charged inside the ball tank and in the path of the insulator also adversely affects game control.

SUMMARY OF THE INVENTION It is an object of the present invention to effectively absorb noise caused by static electricity charged in at least one of a ball tank, a payout passage, and a game ball, and to reduce the absorbed noise from a ground line grounded. The purpose is to prevent electric discharge, to prevent adverse effects of various noises on various control boards and the like that control game control, and to further enhance noise countermeasures.

Is done. The game balls conveyed from the outside are supplied to the ball tank by dropping and temporarily stored therein, and the game balls in the ball tank are finally paid out to the game ball supply tray through the payout passage. By the way, since these ball tanks and payout passages are made of insulating material such as synthetic resin, the game balls collide with the ball tanks or payout passages or game balls to generate static electricity. There is a case that the passage is charged.

However, the game ball directly contacts the conductive member provided in the ball tank or the payout passage, or indirectly contacts through the game ball. As a result, at least any of the static electricity charged in the ball tank, the payout passage, and the game ball is

Then, noise due to the static electricity can be surely absorbed by the noise absorbing means provided on the conductive member or by the noise absorbing means provided near the conductive member. As described above, the noise due to the static electricity removed by the conductive member can be absorbed in advance by the noise absorbing means provided in the ball tank or the payout passage before the grounding via the ground wire, so that the ball tank and the payout can be absorbed. It is possible to reliably prevent not only electrostatic discharge from the passage and the game ball into the air, but also electrostatic discharge from the ground wire to the air, and further enhance noise countermeasures.

In the case where there is an overflow guide passage for overflowing the tray (claim 2), not only the game balls but also these game ball guide passages, a ball passage in the payout device, a game ball guide passage, and an overflow. The static electricity charged in the guide passage and the like can be reliably removed by the conductive member provided in the payout passage.

When the noise absorbing means has a noise absorbing substrate and a noise absorbing element provided on the noise absorbing substrate (claim 3), the noise absorbing element is provided on the noise absorbing substrate. Therefore, the noise absorbing substrate can be easily fixed to both the ball tank and the payout passage.

When the noise absorbing substrate of the noise absorbing means is covered with a transparent case (claim 4), the noise absorbing element on the noise absorbing substrate is protected from dust and dirt by the transparent case. Can be protected.

Further, the noise absorbing means may be any one of a surge absorbing element, a varistor, a coil, a resistor, and a capacitor.
In the case where any one of these components is used as the noise absorbing means, since the internal impedance is high, it is possible to immediately and inexpensively and easily absorb the noise surge component due to static electricity. it can.

Further, when a noise absorbing circuit is provided on the power supply board and this noise absorbing circuit is connected to a ground line (claim 6), the influence of noise on a plurality of control boards for game control is reduced. Without giving the static electricity, the static electricity can be supplied to the noise absorption circuit of the power supply board via the ground line, and the power supply board can absorb the noise.

In the case where the noise absorbing circuit has a surge absorbing element for absorbing a surge component up to a predetermined voltage and a varistor for absorbing noise that cannot be absorbed by the surge absorbing element (claim 7), The surge component of the noise generated up to a predetermined voltage is absorbed by the surge absorbing element, and thereafter, weak noise that cannot be absorbed by the surge absorbing element is absorbed by the varistor. For example, even for a large noise having a surge voltage of 200 V or more, the surge component up to about 200 V is absorbed by the surge absorbing element, and the remaining weak noise can be reliably absorbed by the varistor.
