The heat is removed from the heat sinks 43, 43,..., That is, the temperature rise in the control device 42 is suppressed. Therefore, the temperature rise behind the game board 10 can be further suppressed, the thermal deformation prevention effect of the game board 10 can be further improved, and one fan can be provided for each heat sink 43 without installing a fan. A rational configuration capable of realizing effective heat removal by the fan 45 can be obtained.

Furthermore, the rear surface of the liquid crystal display device 41 and the plate member 31 can be removed by using the wind sent into the duct portion 42c by the fan 45, and the configuration on the rear surface side of the game board 10 can be further rationalized. Can be planned.
In addition, by providing such a temperature adjustment mechanism and heat removal mechanism, a board member made of acrylic resin or the like, which is easily deformed by heat as compared with a conventional wooden game board, can be adopted as the game board 10 without any problem. it can.

  The configuration related to the pachinko machine of the present invention is not limited to the mode described in the above embodiment, and the configuration related to the game board, the control device, the liquid crystal display device, the heat removal mechanism, and the temperature adjustment mechanism. The present invention can be changed as necessary without departing from the spirit of the present invention.

For example, instead of using the air discharged from the duct part for heat removal, a third fan (and a fourth fan) for directly blowing wind on the rear surface of the liquid crystal display device or the upper rear surface of the game board is installed separately. It is also possible.
In addition, the installation position of the adjustment fan can be changed as appropriate, and is not limited to the lower left and right corners described in the above embodiment. If the peripheral edge of the game board, the left and right upper corners of the game board, etc. It may be provided, may be provided independently of the game board, installed behind the game board, or installed on the rear surface of the front door. Furthermore, unlike the above embodiment, the same effect can be obtained even if an adjusting fan is installed so as to send air behind the game board to the front of the game board. In addition, a decorative member, an accessory, or the like that moves (swings) by using the wind generated by the adjusting fan may be installed in the game area or in the space behind the game board. Note that, as described in the above embodiment, the installation in such a manner as to suck in the air in front of the game board has an advantage that it does not easily affect the game ball flowing down in the game area.

Furthermore, in the said embodiment, although the acrylic resin is employ | adopted as a board member of a game board, it is also possible to employ | adopt another synthetic resin. However, the use of an acrylic resin as the plate member has advantages in that the workability is superior and the manufacturing cost can be reduced compared to the case where, for example, polycarbonate is used.
In addition, it is naturally possible to use a wooden board instead of a synthetic resin for the game board. By providing the temperature adjustment mechanism and the heat removal mechanism described in the above embodiment, it is possible to adopt a thinner wooden board than before. It can be a pachinko machine that is environmentally friendly.
