FIG. 2 shows the back side of the pachinko machine, in which an upper tank 13 storing pachinko balls for paying out winning balls, a tank rail 14 for guiding the balls, a count discharging device 15 for counting winning balls, and a safe ball are shown. A detection device 16 for detecting and discharging is provided. Also, FIG.
A rectangular parallelepiped resin control box 18 to which an electronic circuit indicated by a chain line is mounted is attached to a lower left portion, and a motor 7 constituting a pachinko ball launching device is installed below the control box 18. At the center, a cover 17 for covering electrical equipment and the like attached to the back of the game board 3 is attached.

(First Embodiment) This embodiment will be described with reference to FIGS. 3 and 4. FIG. The control box 18 attached to the back of the pachinko machine shown in FIG.
Is made of transparent vinyl chloride resin so that an electronic circuit or the like (not shown) can be seen, and is formed in a rectangular parallelepiped shape. A large number of holes 19 are formed on the surface of the control box 18 for heat radiation of circuit components, and a mounting rib 20 and a hole 21 are provided at a lower end portion. On the other hand, a cover 22 is rotatably mounted via a rotating shaft 24 so as to open the front and rear of the control box 18 so as to cover the surface and preferably also the side surface, so that the control circuit is visible. The cover 22 is made of a metal material, for example, aluminum, copper, iron, permalloy, or the like. In addition, an earth wire 40 is connected to the metal cover 22 and is installed in the ground (not shown). FIG. 4 shows a state in which the control box 18 is covered with the cover 22 to prevent the influence of electromagnetic waves, while FIG. As described above, by allowing the cover to be freely rotatable, it is possible to see the internal electronic circuit when the control box is made of a transparent resin when necessary, and conversely when the control box is used, it is easy to use. Can be closed. Even when the cover 22 is in the closed state, heat can be sufficiently dissipated because a gap is formed with the control box surface. The cover may be formed of a metal plate or the like as described above, or may be formed in a shape having a gap such as a lattice or a concentric circle. Further, in addition to the method described above, the end of the cover and the control box can be freely rotated by a hinge as a method of forming the cover so as to be rotatable. It may be fitted and attached.

(Second Embodiment) This embodiment will be described with reference to FIG. The shape of the control box and the like are the same as those in the first embodiment, and a description thereof will be omitted. From the surface to the side surface of the control box 18, the metal foil 25 is formed in a shape with a cut-out side surface so that the metal foil 25 can be easily opened and closed. It is stuck with an agent. That is, since the metal foil 25 is thin, it can be easily bent by lifting the front portion 27, and when the control box is formed of a transparent resin, the inside of the control box 18 can be seen. Note that a conductive foil such as aluminum, stainless steel, or copper is used as the metal foil 25. Further, an earth wire 40 is connected to the metal foil 25. If the control box is covered with metal foil, the effects of electromagnetic waves and static electricity on the control box can be reduced via the ground wire, and since the cover is made of metal foil that is easily bent, transparent resin You can easily see the electronics in the control box. In addition, since static electricity and the like can be prevented even if the metal foil does not adhere to the entire surface and side surface of the control box, heat dissipation in the control box can be dealt with. The metal foil is shown in FIG.
It is needless to say that it is more desirable to adopt a shape that covers the entire side surface, unlike the case shown in FIG. In that case, the metal foil can be opened and closed by cutting the side surface. Further, as described above, the end portion may be locked with a tape or the like, instead of being attached with an adhesive.

Third Embodiment A third embodiment will be described with reference to FIG . The control box 18 is the same as in the first embodiment. A metal foil 28 is adhered to a substantially concentric elliptical shape having a gap 32 formed on the surface of the control box 18 to prevent static electricity and electromagnetic waves. The concentric circles may be connected to connect the ground wire 40. However, according to various experiments, the ground wire 40 is connected to the concentric center portion 29 in this embodiment as shown in FIG. In addition, metal foil 2
As 8, a conductive material such as copper, aluminum, or stainless steel is used, and the width and interval of the metal foil are formed to appropriate widths. Also, in addition to the metal foil, a metal wire or a metal plate may be adhered to the surface of the control box in the same shape as described above, or may be embedded in a resin forming the surface or formed on the back surface. Good. Note that heat dissipation in the control box is performed through the holes 19.

(Fourth Embodiment) This embodiment will be described with reference to FIGS. FIG. 7 shows an overall perspective view of the control box 18 and the control box 18.
Is the same as that of the first embodiment, and the description is omitted. In the present embodiment, the metal foil 30 is formed in a lattice shape having a gap portion 32 on the surface of the control box 18, and is connected to the ground wire 40 at one end. The metal foil 30 is shown in FIG. 8 (A to A in FIG. 7).
As shown in the cross-sectional view, the control box 18 may be attached to the front surface or the back surface (not shown), or may be attached to the control box 18 as shown in FIG.
