Description

  The present invention relates to a gaming machine including a gaming board having a transparent resin board and a back unit to which a plurality of gaming parts are attached.

  As a gaming machine using a game ball such as a pachinko machine, there is known a gaming machine equipped with a transparent resin board made of an acrylic plate or a polycarbonate plate and a back unit provided on the back surface of the transparent resin board. Yes. The back unit is provided with decorative members such as LED lamps and symbols, a liquid crystal display device, a control circuit board for controlling these devices, and the like.

  The transparent resin board is formed with a game area where the game ball rolls down, and an opening is formed in the game area, and a plurality of game parts are attached to the opening. Note that the gaming parts include a winning device (for example, a start winning device, an attacker device) capable of winning a game ball.

  Such a transparent resin board is liable to generate friction with a game ball that rolls down, and at that time, static electricity is likely to be generated. The generation of static electricity is particularly great in the vicinity of gaming parts that frequently come into contact with gaming balls. This static electricity causes a problem that not only the screen display of the liquid crystal display device constituting the back unit is disturbed but also a malfunction of the control circuit board.

  Regarding this problem, when the game board is fitted into the middle frame, the ground member provided in the back unit of the game board and the metal fitting provided in the middle frame are brought into contact, and the transparent resin board and the ground member of the game board are brought into contact with each other. There has been proposed a gaming machine configured to allow static electricity generated in a transparent resin board to escape outside the gaming machine by bringing them into contact with each other (Patent Document 1).
