Description

  The present invention relates to a gaming machine having a power supply box, for example, in which a board 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).

  The power supply box (PWU) is formed of a metal box 100 such as a sheet metal case because of advantages such as ease of processing, cost, heat dissipation, and noise resistance. Then, a power supply board is mounted on the inner side surface and constitutes an upper plate and a bottom plate, or a hole for airflow is formed on an arbitrary sheet metal surface. In addition, the front plate that appears when the front door is opened is made of a transparent acrylic plate compared to other plates made of sheet metal, and constitutes a power supply device and a setting change device built in the power supply box. The substrates to be viewed are visible. As shown in FIG. 4, the ground connection structure of the power supply box according to the embodiment of the present invention is realized by drawing out the connection of the ground 41 from the board 40 as a connector output and connecting it to the metal box body 100 by the harness 51. This connecting portion is formed so as to be visible from the outside through a transparent acrylic plate.

Specifically, a connector 501 (male type) having a lock engaging portion 42 on the peripheral wall is solder-mounted on the ground 41 of the substrate 40. A connector 502 (female type) having a lock claw 43 on the peripheral wall is attached to one end of the single-line harness 51, and the connector 502 is fitted with a connector 501 soldered to the ground 41 of the board 40. Combined with lock.
On the other hand, a connection fitting 52 made of a U-shaped or O-type washer is attached to the other end of the harness 51, and the connection fitting 52 is screwed and fixed to the ground hole of the metal box 100 with a bolt 10. The ground connection structure. Note that the connection fitting 52 of the harness 51 may be screwed and fixed not only to the ground hole of the metal box body 100 but also to a ground fitting (grounding terminal) provided in the gaming machine housing.

According to the above-described embodiment of the present invention, a reliable connection can be achieved as compared with the conventional fixing to the metal box only by screwing. Further, even if the harness is detached, it can be visually recognized from the outside through the transparent acrylic plate, and this can easily detect the drop-off, leading to prevention of failure and accident.
Further, the lock claw 43 attached to the connector 502 of the harness 51 is engaged with the lock engaging portion 42 attached to the peripheral wall of the connector 501 mounted on the ground 41 of the substrate 40, and the connectors 501 and 502 are fixed to each other. Thus, a more reliable connection is possible.
