Description

  The present invention relates to a pachinko machine.

A typical pachinko machine is provided with a control board and a drive unit on which a large number of electronic components such as a main control board, a payout control board, and a symbol control board are mounted. Each of these boards and drive units, for example, each board, is housed in a dedicated resin storage box and is located on the back side of each pachinko machine erected on the amusement island equipment, that is, inside the amusement island equipment. ing. On the other hand, a player performs a game operation toward a pachinko machine in a pachinko store outside the game island facility.
In the control board and the like, the temperature of the board itself and its surroundings are likely to rise due to heat generated from a large number of electronic components when energized, and each is contained in a dedicated storage box to prevent fraud. It is difficult to dissipate heat in the state. Moreover, in a normal pachinko machine, there are heating parts that generate heat when driven at the start of the game, such as a driving unit other than the control board, for example, a solenoid that drives a variable winning device or a launching motor that drives a launching mechanism. Like the control board, it is arranged on the back side of the pachinko machine.
As described above, in the normal pachinko machine, the heat generating parts such as the control board, the storage box, and the drive unit generate heat, and the back side of the pachinko machine easily rises to a high temperature. The possibility of instability arises.

In order to suppress such temperature rise in the control board and its surroundings, in conventional pachinko machines, a plurality of control board storage boxes arranged on the back side of the front frame (specifically, the back mechanism plate of the front frame) are connected to the ventilation pipe. In addition, a configuration is known in which outside air is blown to a plurality of control board storage boxes through this pipe to cool the control board inside the box (for example, Patent Document 1).
Further, in the conventional pachinko machine, a configuration is known in which an air intake port, an air discharge port, and an air circulation electric fan are disposed in the control board storage box to forcibly release the heat in the control board storage box. (For example, patent document 2).

As in Patent Document 1 and Patent Document 3, in a pachinko machine that introduces outside air (air) as a cooling medium, air in a game store is introduced to control boards in various control board boxes. However, in the amusement store, floating fine foreign matters such as cigarette smoke, dust, and dust are prevalent and it is not always clean air. In the conventional pachinko machine in which such air is sent directly to the control board, foreign matter such as dust and dust enters into the control board storage box together with the cooled air, and the electronic components and wiring patterns on the control board enter. There is a problem that the control board breaks down due to adhesion or the like.
Even if it is configured to blow air through a dustproof filter, sufficient air will not be introduced due to resistance when passing through the filter, resulting in a decrease in ventilation capacity, and an appropriate filter according to the amusement store where the air environment varies. It is difficult to select.
Further, as in Patent Document 2, in a conventional gaming machine in which air in a box is forcibly circulated by an electric fan provided in the board box, the air sent into the control board box is at a lower temperature than in the box. However, there is a drawback that sufficient cooling effect cannot be obtained because air on the back side (especially around the control board box) whose temperature is higher than that in the amusement store or when it is not in operation is sent into the control board box. .

  Therefore, the present invention solves the above-mentioned conventional problems and uses the cooled air in the pachinko store, but without directly introducing the air in the pachinko store, the air temperature on the back side of the pachinko machine, the control board, the drive unit, etc. It is an object of the present invention to provide a pachinko machine that can sufficiently suppress the temperature rise of the heat generating components, and thus can stabilize the operation of the control board and the like.

In order to achieve the above object, a pachinko machine according to the present invention has a front frame of a pachinko machine equipped with a game board and the like, and an outer frame in which the front frame is arranged on the front surface side, and includes a control board and a drive.

Since the circulation path that returns from the arrangement space to the arrangement space through the vent pipe unit is a closed circuit, dirty air in the pachinko parlor store is arranged with control parts such as a control board and a drive unit through the vent pipe unit. There is no intrusion into the placement space.
On the other hand, the outer frame of the pachinko machine can face the inside of the pachinko store, so the vent pipe part of the vent pipe unit is connected to the inside of the pachinko store from the opening window provided in the curtain plate part that is the lower frame part of the outer frame. The air flowing through the ventilation pipe portion through the ventilation pipe portion can be heat exchange cooled by the air in the pachinko parlor. As a result, the air that has been heat-exchanged and cooled returns to the arrangement space to lower the temperature of the arrangement space, or can directly contact the control component to effectively suppress the temperature rise of the control component. Therefore, the stability of the operation of the control components such as the control board and the drive unit can be ensured.
Further, since the vent pipe unit is provided separately from the outer frame, there is an advantage that a conventional wooden frame can be used for the outer frame itself. That is, for example, the manufacturing cost can be reduced as compared with the case where the frame is made of a metal material having good thermal conductivity. When the outer frame is made of wood, the pachinko machine can be easily assembled when attaching a wooden front frame to the outer frame. Of course, it is also possible to incorporate the vent pipe unit later in an additional configuration to the existing pachinko machine.
