DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine, and more particularly, to a gaming machine for playing games by circulating gaming balls.

[0002]

2. Description of the Related Art In recent years, various techniques have been proposed for preventing the influence of static electricity charged on a game ball from affecting a control board on the back of a game board. For example, in a gaming machine that distributes game balls as game balls and pays out prize balls or the like when predetermined conditions are satisfied, a tank for storing game balls supplied from islands of a game arcade is made of conductive plastic. Alternatively, there is a method in which a conductive metal plate is attached to the bottom of the rail, which is the path of the game ball from the tank, and static electricity charged on the game ball is released from the tank or the metal plate to the ground (Japanese Patent Laid-Open No. 6
-39118 publication).

[0003]

However, according to the conventional method, the game balls stored in the tank or the rail flow toward the upper plate or the lower plate in accordance with the payout of the prize ball or the lending ball, When a game ball that has entered the inside of the out port flows outward, the static electricity generated by the flow of the game ball cannot be removed. In particular, in the case of a gaming machine in which a control board is disposed near such a flow path of a game ball, it is necessary to protect the control board from static electricity generated due to the flow of the game ball. No effective proposal has hitherto been made on means for protecting the control board from static electricity generated in the apparatus.

On the other hand, as a technique for protecting the control board from static electricity generated due to the flow of the game ball at the time of winning or the like, the base member on which the control board is disposed is made conductive, and this base member is made external. A configuration is conceivable in which the conductor is connected to the ground by a conductor, and the static electricity flying from the game ball is released from the base member to the ground through the conductor. However,
With this configuration, since noise from the outside of the gaming machine is easily transmitted to the base member through the conductive wire, the control board may pick up the external noise, and this noise may cause a malfunction of the control board. .

Accordingly, the present invention has solved the above-mentioned problems,
For the purpose of protecting the control board from static electricity generated inside the gaming machine and noise generated outside the gaming machine, and ensuring a normal processing operation of the gaming machine, the following configuration is adopted.

[0006]

A gaming machine according to the present invention is a gaming machine for playing a game by circulating gaming balls, and includes a plurality of control boards for controlling operations related to the game. And a conductive member provided at least in a range where the plurality of control boards are provided, and having a predetermined area or more, wherein the conductive member is provided in the conductive member at least during execution of the game. And that the plurality of control boards are disposed on the conductive member while securing the connection between the conductive member and the ground layer of each control board. I do.

According to the gaming machine of the present invention, when the static electricity generated in the gaming machine is discharged and reaches the periphery of the control board, the static electricity is provided in a wide range where the control board is provided. Dispersed in conductive members. For this reason, a potential difference hardly occurs in the conductive member, and the probability that a high voltage is locally generated around the control board is reduced. Therefore, it is possible to prevent static electricity from acting on the control board as noise without letting the static electricity escape to the outside. As a result, it is possible to minimize the possibility of malfunction of the control board due to static electricity charged on the game ball and noise generated outside the game machine.

It is also preferable to provide a conductive member having an area exceeding the total area of the plurality of control boards. This way,
The potential difference generated in the conductive member can be at a lower level.

[0009] It is also possible to provide a ball flow path as a path through which a game ball flows, and to provide a conductive member in a range covering at least a part of the ball flow path. In this case, the static electricity generated by the flow of the sphere in the sphere flow passage can be quickly guided to the conductive member near the generation point.

[0010] A resin plate may be provided between the spherical flow path and the conductive member covering the spherical flow path. This way,
The static electricity generated by the flow of the sphere in the sphere flow path is blocked by the resin plate, and hardly reaches the control board on the conductive member. Therefore, the control board can be reliably protected from static electricity generated during the flow of the sphere.

It is also preferable that the conductive member is formed by laying a plurality of metal plates and has a connecting portion for electrically connecting the plurality of metal plates. According to this configuration, the plurality of metal plates become conductive via the connection portions, and the static electricity guided to one metal plate is dispersed throughout the conductive member. Therefore, the probability that a high voltage is locally generated around the control board is reduced, and it is possible to effectively prevent the static electricity from acting as noise on the control board even if the static electricity does not escape to the outside. In addition, by laying control boards on such a plurality of metal plates, even when one control board and another control board are arranged at a distance from each other, each of these control boards is protected from static electricity and noise. It becomes possible to protect. Therefore, the degree of freedom in the arrangement of the control board can be increased while the normal processing operation of the control board is ensured.

A game board having a game area formed on a front surface thereof; and a mechanism plate which is a plate body provided on the back surface of the game board in an overlapping manner and on which various mechanisms necessary for executing the game are mounted. Among the plurality of metal plates, at least one metal plate is laid on the game board, another metal plate is laid on the mechanism plate, and the connection portion is provided on at least one of the one metal plate and the other metal plate. It is also preferable that the connecting portion is provided in such a manner that one metal plate and another metal plate are electrically connected when the mechanism plate is superimposed on the back surface of the game board. With this configuration, when the mechanism plate is superimposed on the back surface of the game board, one metal plate and another metal plate are in a conductive state via the connection portion. Therefore, even when control boards are provided on each of the game board and the mechanism board, it is possible to protect these control boards from static electricity and noise. Therefore, it is possible to efficiently arrange a large number of control boards while ensuring a normal processing operation of the control boards.

The connecting portion provided on one metal plate or another metal plate may have an elastic force in the direction of another metal plate or one metal plate. In this way, when the mechanism plate is superimposed on the back surface of the game board, one metal plate and another metal plate can be reliably connected by the elastic force of the connection portion.

As one of the plurality of control boards, a power supply board for converting AC power supplied to the gaming machine to DC is provided, and other boards other than the power supply board are arranged around the power supply board.
It is also desirable that a DC power be supplied from the power supply substrate to another substrate. By arranging another board to which DC power is supplied from the power board around the power board, a supply path of DC power from the power board to the other board is shortened. Therefore, noise is less likely to be picked up in the middle of the supply path, and it is possible to further reduce the probability that a malfunction of the control board will occur.
