Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine such as a pachinko game machine and an arrangement ball game machine, and more particularly to a ball game machine capable of reducing electromagnetic noise generated when a game ball is hit. .

[0002]

2. Description of the Related Art In a pachinko game machine or an arranged ball game machine as a ball-and-ball game machine, friction between balls or ball flow occurs in a process of circulating game balls in an island facility or in a process of flowing down a discharge route in the game machine. The game balls are charged with static electricity due to friction with the road contact surface.

[0003] A game ball charged with static electricity of such a high potential generates a corona discharge or a spark discharge when approaching or in contact with a conductor (for example, a metal part) having a different potential, and generates an electromagnetic wave as electrons move. This electromagnetic wave acts as an external noise (noise) on electronic circuits such as various control devices and peripheral equipment of the gaming machine, and has an adverse effect such as malfunction.

Conventionally, as a countermeasure to mitigate the influence of the above-mentioned noise, for example, a game such as a metal plate or the like is laid on the bottom surface of a spherical flow path such as a supply tray and a ground wire is connected to the conductor. The discharge phenomenon has been suppressed by releasing the charged electric charge.

[0005]

However, even if the above noise countermeasures are taken, it is not possible to completely prevent the generation of external noise, and in particular, various measuring devices for gaming machines and the like which are easily affected by noise. However, there still remains a problem that accurate data cannot be collected, and a problem such as malfunction of a data collection device of the management device or an information disclosure device that discloses game-related data to a player remains.

Accordingly, the present inventors have thoroughly investigated the state of generation of electromagnetic waves in the entire game machine using a high-sensitivity noise measuring device in order to thoroughly clarify the source of the noise.

[0007] As a result, it has been found out that a strong electromagnetic wave (noise) is generated in the process in which the game balls are supplied from the supply plate to the launching rail and are ejected by the launching punch. This is because, due to a large potential difference between the potential of the game ball flowing down from the upper plate and the launching punch provided in the launching unit, discharge occurs at the moment the launching punch strikes the game ball, and emits electromagnetic noise. It is considered something.

The present invention has been devised to solve the problems found as described above, and eliminates or reduces the electromagnetic noise generated in the process in which a game ball is repelled by a launching punch. It is an object of the present invention to provide a ball-and-ball game machine capable of performing such operations.

[0009]

And a launch unit (U) having at least a launch unit, wherein the launch rail and the launch punch are formed of a conductive material,
In addition, they are electrically connected so that they have the same potential.

[0010] This eliminates the occurrence of a potential difference between the game ball sent out on the launch rail and the launching punch, so that no discharge is generated when the launching ball hits the game ball, and no noise is generated. Can be effectively prevented.

The firing unit includes a conductive mounting base on which the firing punch and the driving source are mounted, the mounting base and the firing punch are electrically connected, and the firing rail and the firing punch are connected to each other.

The conductive member may be a metal plate disposed on the mounting portion so as to extend over the firing rail and the firing unit, or may be formed of a wiring cord.

Further, the conductive member may be the mounting portion itself made of a conductive material. According to this, since it is not necessary to separately attach a conductive member, the game ball and the launching punch can be set to the same potential with a simple configuration without increasing the assembling process of the ball game machine.

Further, it is preferable that an electromagnetic shield is provided on any one of the back surfaces of the mounting portions. According to this, even when noise is generated based on the potential difference between the game ball and the launching punch, the noise is transmitted to the electromagnetic shield (for example,
Metal plate, conductive film, conductive paint application, conductive resin molding, etc.) to prevent noise from entering the ball game machine and causing malfunctions of control devices. can do.

According to this, the electric charge of the game balls and the launching punch can be released to the game board storage frame having a relatively large capacitance, so that the generation of noise can be more reliably prevented.

In addition, the firing rail is mounted on one side of the game board storage frame, the firing unit is mounted on the other side, and each of the mounting sides is electrically connected to the game board storage frame. With a simple configuration,
The game board storage frame, the launch rail, and the launch unit can have the same potential.

As a result, it is possible to more reliably prevent external noise from invading electronic circuits such as various control devices and measurement devices provided in the gaming machine and causing malfunctions and the like.

In this embodiment, the case where the wiring cord C is used as the conductive member for electrically connecting the firing rail 38 and the firing unit U has been described. However, the present invention is not limited to this. A plate may be used to connect between the launch rail 38 and the launch unit U.

Also, as described in the description of the mounting portion 6, when the mounting portion 6 is formed of a conductive resin or metal, the mounting portion 6 itself and the firing rail 38 are fired without using the wiring cord C. Conduction with the unit U can be achieved. In this case, the electrical contact between the firing rail 38 and the mounting portion 6 may be made via a screw B2 screwed into the mounting portion 6.

Further, the firing rail 38 and the firing unit U
If the launch unit U and the conductive game board housing frame 5 are connected to each other via a conductive member such as a wiring cord in addition to the connection with the Since it is possible to efficiently escape to the game board storage frame 5 having a large electric capacity, the entire firing unit U including the game ball Q, the firing rail 38 and the firing punch 45 can be maintained at the same potential more reliably.
