When the fan 30 of the air blower 26 is normally rotated, air is sucked from the suction port 26A of the blower 26 and made to blow off to a front glass 18. If the heater 32 is turned on at such a time, the air made to blow off to the glass 18 becomes warm air, whereby the fogging of the glass 18 is removed and prevented. Meanwhile, when the fan 30 of the air blower 26 is reversely rotated, the air is made to blow to a camera main body 22. If the heater 32 is turned off at such a time, the camera is cooled.
