Patent abstract

A camera is covered with a camera housing. The camera and the camera housing form a shooting window portion of a double structure having a clearance. A blowing tunnel communicated with the clearance of the shooting window portion is arranged on each of both sides of the shooting window portion. A blower sends a wind to the shooting window portion through the blowing tunnel. Further, a heater for heating the air sent to the shooting window portion is arranged in the blowing tunnel. Thus, dew condensation preventing ability can be improved by such a construction.
