It extends in the horizontal direction toward the 7C, 7R side. The second circuit device 11 is mounted with the heat radiation block 15 side up. The second circuit device 11 controls a liquid crystal display device (not shown) or a production reel other than the reels 7L, 7C, and 7R. On the bottom plate of the cabinet 3, a power supply unit 17 for supplying necessary power to the gaming machine 1, and medals,
A hopper 19 for paying out game media such as coins or tokens is placed. A door (not shown) is attached to the front of the cabinet 3. The door is provided with a display window for displaying symbols drawn on the reels 7L, 7C, 7R, a start lever for starting rotation of the reels 7L, 7C, 7R, and the like. FIG. 2 is a perspective view showing the appearance of the second circuit device 11. The second circuit device 11 includes a transparent cover 13,
It comprises a circuit board 21 and a base 23. The circuit board 21 is fitted into a recess on the upper surface of the base 23,
It is fixed by. The transparent cover 13 is made of synthetic resin and is formed in a box shape with an open bottom. On the upper surface of the transparent cover 13, an opening 27 slightly larger than the upper surface of the heat radiation block 15 is provided. On the left and right side surfaces of the transparent cover 13, two projecting portions 29 are formed. On the left and right side surfaces of the base 23, two projections 31 each having a fixing hole (not shown) are formed. The transparent cover 13 is assembled on the base 23 by aligning the projection 29 of the transparent cover 13 with the projection 31 and screwing a one-way screw 33 into a fastening hole of the projection 31 of the base 23 from above. Also, as shown in FIG.

And the like, a connector part 39 for communication, and a metal heat dissipation block 15 having a plurality of blades 41 for releasing heat generated by the electronic circuit 37 to the outside of the second circuit device 11. ing. This heat radiation block 15
Has a width substantially equal to one side of the circuit board 21, and one end thereof is exposed to the outside of the transparent cover 13 through the opening 27. Since the heat generated by the electronic circuit 37 is transmitted to the outside of the transparent cover 13 through the heat radiation block 15, it is possible to suppress an increase in the temperature inside the second circuit device 11. Also, as shown in FIG. 1, by attaching the second circuit device 11 with the heat radiation block 15 side up, the heat generated by the electronic circuit 37 moves upward, that is, to the heat radiation block 15 side. Heat can be efficiently released to the outside. Although the embodiment has been described above, the present invention is not limited to this. In the embodiment, one end of the heat radiation block 15 is
It projects outside the transparent cover 13 through the opening 27, but is not limited to this. It is sufficient that at least one end of the heat radiation block 15 (for example, a part or one surface of the heat radiation block 15) is exposed to the outside of the transparent cover 13 through the opening 27 (for example, comes into contact with outside air). For example, the surface of one end of the heat radiation block 15 may be flush with the outer surface of the transparent cover 13 or may be located slightly closer to the circuit board 21 than the inner surface of the transparent cover 13. In this case, one end of the heat radiation block 15 does not protrude outside the transparent cover 13, so that the space inside the housing can be effectively used. When the surface of one end of the heat radiation block 15 is located closer to the circuit board 21 than the surface inside the transparent cover 13, the distance between the surface of the heat radiation block 15 and the surface inside the transparent cover 13 is improper. It is preferable that the distance is set to be equal to or less than the distance that can prevent the occurrence of the light. In the embodiment, the second circuit device 11 is mounted on the left side of the inner surface of the cabinet 3.

In the embodiment, one end of the heat radiation block 15 of the second circuit device 11 is exposed to the outside of the transparent cover 13. However, the heat radiation block 15 can be connected to any circuit device such as the first circuit device 9. And one end thereof is provided with a transparent cover 13.
May be exposed outside. In the embodiment, the heat radiation block 15 is disposed at one end of the circuit board 21, but is not limited to this, and can be disposed at any position. In addition, heat dissipation block 1
Any shape can be adopted as the shape of 5. In the embodiment, the second circuit device 11 is mounted with the heat radiation block 15 side up.
However, the present invention is not limited to this, and can be attached in any direction. The circuit device of the embodiment is mounted on a slot machine, but is not limited to this.
