1, the negative pressure acts on these second through holes 47, and the air inside the casing 31 is forcibly sucked out.

At the same time, since the first through holes 45 of the casing 31 are exposed to the outside of the housing 4 through the card insertion slot 23, the air outside the housing 4 through the first through holes 45 is formed. That is, the cold outside air is
Actively taken into the interior. Moreover, the first through hole 4
5 has a larger diameter C as it progresses toward the first opening end 45a opened to the outside of the casing 31, so that the outside air can be efficiently taken in, and the amount of outside air guided into the casing 31 can be reduced. Increase.

As a result, when the fan 18 is driven, the outside air flows through the inside of the casing 31, so that the outside air actively cools the circuit component 38, and the hot air of the circuit component 38 together with the outside air becomes the second air. It is sucked into the accommodation room 21 through the through hole 47. Therefore, sufficient air permeability inside the casing 31 can be ensured, and accordingly, the heat radiation of the circuit component 38 is improved, and
It is difficult for the heat of the circuit component 38 to be trapped inside.

Therefore, the operating environment of the circuit component 38 can be maintained at an appropriate level, and the function deterioration and malfunction of the PC card 30 can be prevented. In the first embodiment, the first through hole 45 is formed in the rear wall 31e of the casing 31 so that the outside air is positively taken into the inside of the casing 31, but the present invention is not limited to this. There is no restriction, and the first through hole 45 may be omitted.

Even in such a configuration, the circuit components 38

FIG. 8 discloses a third embodiment of the present invention. The third embodiment is different from the first embodiment in the configuration for mainly releasing the heat of the circuit component 38 to the outside of the casing 31.
