<Third Embodiment>
Next, a third embodiment according to the present invention will be described. FIG. 10A is a schematic diagram of the slot machine according to the present embodiment, and FIGS. 10B to 10D illustrate that the slot machine according to the present embodiment is used as a game platform base (so-called island). It is explanatory drawing which shows the mode of each exhaust_gas | exhaustion at the time of installing.
[0071]
In the present embodiment, a rear upper ventilation hole 105 and a rear upper ventilation hole 108 are formed as an upper ventilation part 290 of the cabinet 102, and a lower lower ventilation hole 106 and a bottom surface are formed as a lower ventilation part 291 of the cabinet 102. A rear vent 109 is formed. These four vent holes are one elongated vent hole extending in the width direction of the cabinet 102. Of course, a plurality of round holes or square holes in a horizontal row may be used in place of such elongated vent holes.
[0072]
With this configuration, as shown in FIG. 10 (b), outside air is taken in from both the rear lower vent hole 106 and the bottom rear vent hole 109, and the rear upper vent hole 105 and the upper rear vent are passed through. Hot air in the cabinet is exhausted from both of the pores 108. In particular, since the hot air rising in the housing is discharged as it is without changing the direction from the vent hole 108 at the rear of the upper surface, efficient exhaust heat can be achieved.
[0073]
The structure of the island where the slot machine is installed varies from store to store. For example, as shown in FIG. 10 (c), the base X on which the slot machine is placed is relatively long in the front-rear direction, The vent hole 109 may be blocked. However, according to the slot machine of the present embodiment, the other three vent holes function sufficiently, so that heat is exhausted without difficulty.
[0074]
Further, as shown in FIG. 10 (d), both the base X on which the slot machine is placed and the upper portion Y of the island are long in the front-rear direction, and the upper surface rear vent hole 108 and the bottom rear vent hole 109 are provided. The case where it is blocked is also assumed. However, according to the slot machine of this embodiment example, the vent hole 105 at the upper back and the vent hole 106 at the lower back are not blocked by the base X or the upper portion Y of the island, so that exhaust heat in the housing is promoted. be able to.

<Fourth embodiment>
Next, a fourth embodiment of the present invention will be described. FIG. 11 is a main part view of the present embodiment, in which a dustproof net 1000 is attached to the ventilation part 290 above the rear part of the cabinet 102. The dustproof net 1000 is attached to the cabinet 102 by screws or the like, for example. In the case where a relatively large vent is provided, such a dustproof net may be attached to prevent dust from entering the housing. In addition, it cannot be overemphasized that the dustproof net | network 1000 can be similarly attached to another ventilation part.
[0076]
【The invention's effect】
As explained above, the present invention Slot machine The heat generated inside the housing can be efficiently discharged to the outside at a relatively low cost.
