Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a game machine such as a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, in a pachinko machine as a game machine, a rail for dividing a game area is mounted on the front of the game board, and various prize machines, character devices, display devices, and gates are provided in the game area. A mouth, a windmill, a guide nail, etc. are provided. And the ball (pachinko ball) fired from the launching device
Is guided to the rails and launched into the game area, whereby a game (pachinko game) is performed.

[0003]

By the way, a ball fired in a game area in front of a game board is easily charged with static electricity, and the static electricity charged on the ball causes a control circuit device related to a game or the like. (Also referred to as a control board), which sometimes malfunctioned.

[0004] An object of the present invention is to provide a gaming machine capable of preventing a problem caused by static electricity charged on a ball in view of the above problems.

[0005]

In order to achieve the above object, a gaming machine according to a first aspect of the present invention has a gist as described in claim 1. Therefore, when the ball is discharged from the launching device and guided to the rail and launched into the game area, if the ball is charged with static electricity, the static electricity of the ball passes through the rail and the conductive connection member, respectively, to the conductive Flow into the part and is discharged in the conductive part. For this reason, it is possible to prevent problems caused by static electricity charged on the sphere. Since the conductive connection member is mounted on the base frame side including the support portion, unlike when the conductive connection member is mounted on the game board side, when the game board is attached to or detached from the support portion of the base frame or when the game board is transported. In addition, it is possible to prevent the conductive connection member from being inadvertently damaged by hitting an object.

[0006] The gist of the gaming machine according to the second invention is as described in claim 2. Therefore, when the ball is discharged from the launching device and guided to the rail and hit into the game area, if the ball is charged with static electricity, the static electricity of the ball is attached to the front frame body via the rail and the conductive connection member, respectively. Flows into the conductive member forming the conductive part of
Discharge occurs in the conductive member. For this reason, it is possible to prevent problems caused by static electricity charged on the sphere.

A third aspect of the present invention provides a gaming machine having a gist as described in claim 3. Therefore, the conductive connection member having elasticity has one end elastically pressed against the rail or a conductive member connected to the rail, and the other end elastically pressed against the conductive portion of the front frame, The rail and the conductive portion of the front frame can be easily and reliably connected without poor connection. Therefore, it is possible to eliminate the trouble of electrically connecting the rail or the conductive member connected to the rail using an electric wire or the like and the conductive portion of the front frame. Further, when attaching and detaching the game board to and from the base frame, it can be dealt with by moving one end of the conductive connecting member to and away from the rail or the conductive member connected to the rail, and the conductive connecting member is attached to the game board. Inconvenience which becomes an obstacle of desorption can also be reduced.

A gist of a fourth aspect of the present invention is a gaming machine according to the fourth aspect. Therefore, when the ball is discharged from the launching device and guided to the rail and hit into the game area, if the ball is charged with static electricity, the static electricity of the ball is attached to the front frame body via the rail and the conductive connection member, respectively. Flows into the conductive member forming the conductive part of
Discharge occurs in the conductive member. For this reason, it is possible to prevent problems caused by static electricity charged on the sphere.

A fifth aspect of the present invention provides a gaming machine having a gist as described in claim 5. Therefore, when the ball having static electricity comes into contact with the conductive portion of the game component of the game board, the static electricity of the ball flows through the conductive portion of the game component to the rail, and passes through the conductive connection member at the conductive portion of the front frame. Discharged. For this reason, the trouble caused by the static electricity charged on the sphere can be further prevented.

Further, a gaming machine according to a sixth aspect of the present invention has a gist as set forth in claim 6. Therefore, when the ground circuit is grounded, the static electricity of the ball flows to the conductive portion of the front frame via the rail and the conductive connection member, and flows to the ground circuit of the gaming machine. For this reason, it is possible to reliably prevent problems caused by static electricity charged on the sphere. When the earth circuit is not grounded, the static electricity charged on the sphere flows through the rail and the conductive connecting member to the conductive portion of the surface frame, and is discharged at the conductive portion.

[0011] A gaming machine according to a seventh aspect of the invention has a gist of the structure as set forth in claim 7. Therefore, it is possible to prevent the current from flowing through the ground circuit of the gaming machine from flowing back toward the conductive portion of the front frame by the backflow prevention means.

[0012] Further, a gaming machine according to an eighth aspect of the present invention has a gist as set forth in claim 8. Therefore, when the current collecting member installed away from the surface frame is connected to the ground circuit through the backflow prevention means, after the static electricity collected in the current collecting member flows to the ground circuit,
The problem that the static electricity flows back toward the current collecting member can be prevented. Also, when the board ground of the control board is connected to the ground circuit via the backflow prevention means, the current of the board ground of the control board flows to the ground circuit via the backflow prevention means, so that the control board can be protected. it can. In addition, it is possible to prevent the current flowing in the ground circuit from flowing back toward the control board by the backflow prevention means.
