PROBLEM TO BE SOLVED: To provide a projector device which efficiently removes dust of an air filter regardless of an orientation of arrangement of the air filter, and is easy in maintenance. SOLUTION: The projector device includes: a blower 10 which exhaust outside air from an exhaust port after sucking the outside air from an air suction port 4 and cooling the inner part of a body 2a; an air filter 16 arranged crossing an air channel 9 communicating the air suction port 4 and the exhaust port and collecting dust contained in the outside air; a dust removing body 26; and a dust accommodation part 25a which accommodates the removed dust. The dust removing body 26 consists of a dust removing brush 23 arranged out of the air channel 9 and removing dust of the air filter 16; and a removing brush 24 which removes dust attached to the dust removing brush 23. The tip of the dust removing brush 23 and/or the removing brush 24 is inclined to pierce the dust containing part 25a. Dust is reliably removed even when the air filter 16 is arranged in any orientation inside the body 2a. COPYRIGHT: (C)2010,JPO&INPIT
