Abstract: PURPOSE:To cope with fine dust, temperature rise, and a noise, and to obtain an optical disk library device capable of dealing with high density recording by providing an air suction fan, an outlet port with a throttle, an electrostatic air filter, and a power unit. CONSTITUTION:The air suction fan 11 sucks air into the inside of a machine. The sucked air is heated by the power unit 12, and the greater part of it is exhausted to the outside of the machine from the outlet port 13 with the throttle. On the other hand, the atmospheric pressure of the clearance of the power unit 12 is higher than the outside because of the throttle installed at the outlet port 13, and the air permeates to the outside of the device through the electrostatic air filter 14, and fresh air is supplied. Through this constitution, since the harmful mist-shaped dust is removed by the electrostatic air filter, and a heat generating source is separated by providing the power unit with the air suction fan and the outlet port with the throttle, the heat generating part is pressurized, and the greater part of heated air is exhausted directly. At the time of the switch-off of power too, the air intrudes only by diffusion, and cleanliness can be maintained sufficiently.
