Description

  The present invention relates to a ground connection structure for a gaming machine substrate suitable for use in, for example, a power supply box, in which a substrate on which an electric circuit is mounted is covered with a metal box.

  One of the gaming machines is a slot machine. In the slot machine, a reel mechanism having three rows of reels is incorporated on the front surface of the main body, and a display panel for performing so-called effect display is provided separately from these reels.

  In the above configuration, when the rotation start lever is operated by the player, the game starts, and the gaming machine described above rotates the three rows of reels at a predetermined speed to display a specific effect on the display panel. Next, when a stop key is operated by the player, stop control of the reels in three rows is sequentially performed. Then, when specific pictures (for example, number 7) drawn on the stopped three rows of reels are aligned on the winning line, a display is made on the display panel to notify that a jackpot has occurred.

  By the way, when the board on which the electric circuit for controlling the gaming machine is mounted is covered with a metal box, for example, in the power supply box, the periphery of the board fixing hole is a ground pattern for solder plating, In addition, the boss for fixing the screw is formed integrally with the box with a metal to form a ground connection structure. That is, fixing the board with screws meant ground connection (see, for example, Patent Document 1).
