Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine for suppressing static electricity generated in a pachinko ball,
The present invention relates to a pachinko game machine for removing static electricity charged on a pachinko ball paid out from a prize ball tank formed on the back of a game machine.

[0002]

2. Description of the Related Art Recent pachinko game machines are provided with various objects in order to increase the interest of players using the pachinko game machines by changing game contents. Under such circumstances, the pachinko game machine incorporates a large number of electronic control circuits for controlling various devices including the control of such a bonus item. For example, various circuits such as an accessory control circuit, a display circuit, or a prize ball discharge control circuit are incorporated. For such control, an electronic control circuit including a microcomputer or the like has become mainstream, and its structure has become very complicated. by the way,
Pachinko balls used in pachinko game machines are formed of iron, which is a conductor, and have been polished, etc., but the pachinko balls are charged by the generation of static electricity due to friction with the abrasive. Becomes Further, in the pachinko balls used in circulation, static electricity is also generated due to friction between the pachinko balls or friction between the pachinko balls and a passage in which a plastic material or a celluloid material is used.

[0003] Therefore, in the pachinko game machine, there has been a problem that a malfunction such as a malfunction occurs due to the static electricity generated in the pachinko ball. That is, as described above, in the current pachinko game machine, since various devices are controlled by an electronic circuit formed by a microcomputer,
The electric charge charged to the pachinko ball is generated as a high voltage pulse like a discharge phenomenon, and is generated as noise in the electronic circuit. For this reason, such electronic circuits that are vulnerable to noise have caused various failures such as circuit malfunctions and operation stoppages due to static electricity being generated as pulse noise from pachinko balls. Therefore, various approaches have been taken from the viewpoint of hardware and software as countermeasures against such static electricity. However, these are effective against relatively small pulse noise, but with large pulse noise such as electric discharge, a voltage exceeding the withstand voltage of the electronic circuit is applied and each electronic circuit is physically destroyed. It was not something that could deal with the problem of getting lost.

On the other hand, the pachinko balls are circulated from the bottom to the top in the island facility and supplied to each pachinko game machine. There are places where pachinko balls are collected in large quantities. In such a place, pachinko balls collide with each other and static electricity is particularly likely to be generated. In view of this, various pachinko game machines that have taken measures against static electricity have been developed. As one example, a pachinko game machine disclosed in Japanese Patent Application Laid-Open No. 5-305177 is provided with a pachinko ball antistatic function in a payout channel connected to a prize ball tank on the back side of the pachinko game machine. Hereinafter, a conventional pachinko game machine disclosed in this publication will be briefly described with reference to the drawings. FIG. 10 is a plan view showing a part of the payout channel of the pachinko game machine, showing a state in which a cover is removed.

The pachinko game machine is provided with a replenishing gutter for replenishing pachinko balls for each of the arranged islands, and configured so that the pachinko balls fall into the prize ball tank of each pachinko game machine at a predetermined timing. I have. Then, the pachinko ball is paid out as a prize ball based on a predetermined command from the prize ball substrate flowing down the payout channel from the prize ball tank located at the uppermost stage. Such a configuration of the payout flow path shown in FIG. 10 includes a prize ball discharge path 101 and an excess ball discharge path 10.
2. The communication path 103 and the ball-passing path 104 are formed of a plastic material or the like. A gutter cover 111 that covers the flow path is provided, and a stop hole 105 formed in or inside the flow path matches a screw hole 112 formed in the gutter cover 111, and a screw (not shown) is formed. The gutter cover 111 is attached by fastening.

In the conventional pachinko game machine, the prize ball tank (not shown) and the gutter cover 111 are formed of a charge-eliminating resin in order to solve the above problems. The static elimination resin is, for example, an ABS resin containing several percent of a carbon-based ultrafine fiber substance. Then, the opposite ions of the charged pachinko sphere gather at the tip of such a carbon-based ultrafine fiber substance, thereby causing a neutralization phenomenon and causing a static electricity to be corona-discharged into the air.
Therefore, the pachinko balls flowing down each passage are removed by the corona discharge of the charged electric charge by the charge removing resin, thereby preventing the above-mentioned adverse effect on the electronic circuit.

[0007]

However, in the pachinko game machine provided with the static elimination means shown in the conventional example,
Certainly, it can be evaluated in that it has the effect of removing static electricity, but it leaves a problem in that it is not practical in terms of cost. That is, although it is more effective in eliminating static electricity on the back side of the pachinko game machine provided with the electronic circuit than other conventional pachinko game machines, the prize ball tank and gutter cover are made of ABS resin. In this case, the price was higher than that of commonly used plastic materials. On the other hand, the static electricity of the pachinko ball generated in the pachinko game machine is likely to be generated even when the amount of movement of the pachinko ball is large, such as when the pachinko ball is transmitted through the firing rail and released into the front game area. Therefore, as another conventional example having a static elimination effect, a discharge member is provided on a guide rail (JP-A-7-24111), or a discharge member is provided on a shaft of a windmill provided in a game area. (Japanese Patent Application Laid-Open No. Hei 7-31745) are disclosed. However, as described above, considering that a large amount of static electricity is generated in a prize ball tank or the like where pachinko balls collide violently, and that the static electricity has a particularly bad effect on an electronic circuit, the game area of the pachinko game machine is considered. That is, it can be said that it is more effective to remove electricity on the back side than to provide electricity removal means on the front side.

Accordingly, an object of the present invention is to provide a pachinko game machine having an inexpensive static eliminator for effectively preventing the adverse effect of static electricity on an electronic circuit in order to solve such a problem.

[0009]

A pachinko game machine according to the present invention is provided with a prize ball tank disposed on a mechanical panel formed on the back side of the pachinko game machine and arranged at the uppermost stage of the pachinko game machine. Pachinko balls falling from the device are temporarily stored upon receipt, and with the payout of the prize balls, the pachinko balls are sequentially paid out of the prize ball tank through a channel formed in the pachinko game machine, And a swinging means provided on the flow path, wherein a contact portion of the swinging means with the pachinko ball flowing down is electrically connected to the ground side. Further, in the pachinko game machine of the present invention, it is preferable that the swinging means is a ball level provided on a tank rail connected to the prize ball tank.

Further, in the pachinko game machine of the present invention, the swinging means has a swinging means main body formed of an insulating material, and a metal plate is disposed on a contact surface with the pachinko ball. It is desirable that the metal plate be conductive to the ground side. Further, in the pachinko game machine of the present invention, the swinging means is such that the swinging means main body is formed of an insulating material, and a conductive cover for covering the swinging means main body is mounted, and the cover is provided. It is desirable that it be conducted to the ground side.

Further, in the pachinko game machine according to the present invention, the rocking means has a rocking means main body formed of an insulating material, and the rocking means main body is penetrated by a brush made of conductive fiber. It is desirable that the brush be electrically connected to the ground. Further, in the pachinko game machine of the present invention, the swinging means is such that the swinging means main body is formed of an insulating material, the swinging means main body is penetrated by a wire, and the wire is connected to the ground side. It is desirable that it is done. Further, in the pachinko game machine of the present invention, it is desirable that the swinging means itself is formed of metal and connected to the ground side.

In the pachinko game machine of the present invention having such a configuration, many pachinko balls discharged from the replenishing device into the prize ball tank and violently collide with each other in the prize ball tank. As a result, a lot of static electricity is generated, but when the charged pachinko balls come into contact with the swinging means when they are sequentially dispensed through the channel formed in the pachinko game machine, the contact portion is formed. Since the electric charge is conducted to the ground side, the electric charge charged in the pachinko ball moves to the ground side and is discharged. Therefore,
It was possible to effectively prevent static electricity generated in the pachinko ball from adversely affecting an electronic circuit disposed in the vicinity of the flow path, and to provide an inexpensive static eliminator as a preventive means.

[0013]

Next, an embodiment of a pachinko game machine according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a rear view showing the pachinko game machine according to the present embodiment. The pachinko game machine 1 pays out a predetermined amount of pachinko balls as prize balls.
