[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine in which a decorative member is arranged on a game board, and the game board is detachably attached to a storage frame. More specifically, the present invention relates to a ball game machine. The present invention relates to a ball game machine capable of removing noise components such as generated electrostatic noise.

[0002]

2. Description of the Related Art In a pachinko game machine as a ball game machine in which a metal pachinko ball falls along a game board surface, a decorative sheet member (for example, a celluloid sheet or the like on which an arbitrary print is applied) on the game board surface is used. ) And a game ball generate static electricity, and discharge (spark) between the game ball and the game equipment such as nails and various types of accessories arranged on the game board and the game ball.
Cause

As described above, static electricity generated by friction of a game ball or the like causes electrostatic noise or electromagnetic wave noise when electric discharge occurs between the game equipment and the decorative member, and the control circuit of the pachinko gaming machine. It was a cause of malfunction.

[0004] Therefore, conventionally, the surface of the play equipment or decorative members such as the various kinds of accessories provided on the play board is plated with metal, or the play equipment itself is formed of a conductive resin or the like. At the same time, attempts have been made to ground these playground equipment and decorative members to prevent static electricity from being charged and to prevent electrostatic noise and electromagnetic noise.

[0005]

However, in the above case, a grounding wire is provided for each of the play equipment and the decorative member plated with metal, and the play equipment and the decorative member formed of conductive resin. However, there is a problem in that the work efficiency when assembling the play equipment or the like to the game board is poor because it is necessary to connect the ground wire to the back side of the game board and ground it.

The present invention has been made in order to solve the above problems, and eliminates the potential difference between the game equipment such as nails and various types of accessories provided on the game board and the decorative member, thereby eliminating the noise caused by the discharge. The main purpose is to provide a ball game machine that can effectively prevent the occurrence.

[0007]

To achieve the above object, a ball game machine according to the present invention is a board-shaped base material (for example,
A decorative sheet member (for example,
A game board (eg, nails, various accessories, etc.) and a decorative member (eg, a decorative member that surrounds the periphery of the display) are mounted on a game board formed by stacking celluloid sheets, etc. In the ball game machine in which the game board is detachably attached to a housing frame on the main body side, the game board has a conductive sheet member having conductivity between the base material and the decorative sheet member ( For example, a conductive polymer such as polyacetylene, or a sheet made of a conductive plastic with a filler added) is sandwiched, and each of the above-mentioned play equipment and decorative member are mutually connected via the conductive sheet member on the game board. It is configured so as to be electrically connected.

Further, as described in claim 2, it is possible to provide a connecting means for electrically connecting the housing frame and the conductive sheet member.

Further, as set forth in claim 3, a conductive sheet member exposed portion where a part of the conductive sheet member covered with the decorative sheet member is exposed at a side edge portion of the game board. The connection means may be formed of a conductive game board locking member that engages with the conductive sheet member exposed portion and fixes the game board.

Further, as described in claim 4, the play equipment and the decorative member mounted on the game board may be grounded via the conductive sheet member.

[0011]

According to the ball game machine of the present invention, the game board is
Between the board-shaped base material and the decorative sheet member, a conductive sheet member having conductivity is sandwiched, and the play equipment and the decorative member are attached so as to be electrically connected to each other through the conductive sheet member. Therefore, since the respective play equipments and the decorative members have the same potential, it is difficult for the discharge to occur, so that it is possible to prevent the generation of electrostatic noise and electromagnetic noise.

Moreover, since the play equipment and the decorative member are brought into electrical contact with the conductive sheet member only by attaching them to the game board with, for example, metal nails, the play equipment can be easily conducted. The work efficiency can be improved.

Further, as described in claim 2, when a connecting means for electrically connecting the housing frame and the conductive sheet member is provided, the game machine is provided through the conductive sheet member. Since the decoration member and the storage frame can be made to have the same potential, it becomes more difficult for discharge to occur, and electrostatic noise and electromagnetic noise can be more effectively prevented.

Further, as described in claim 3, the connecting means is constituted by a conductive game board locking portion which engages with a conductive sheet member exposed portion of the game board and fixes the game board. In such a case, when the game board is attached to the storage frame, the conductive sheet member and the frame can be electrically connected only by engaging the game board locking member with the game board. , Work efficiency can be improved.

As described in claim 4, when the play equipment and the decorative member mounted on the game board are configured to be grounded through the conductive sheet member, As described above, it is not necessary to perform a troublesome work such as connecting an earth wire to each play equipment, and it is possible to efficiently ground the equipment.
