<P>PROBLEM TO BE SOLVED: To provide a projector for sending clean air and for efficiently cooling an object to be cooled. <P>SOLUTION: This projector is equipped with: a light source; a light modulating device that modulates the flux of light emitted from the light source on the basis of image information to form an optical image; a projection optical system that projects the formed optical image; and an exterior housing that accommodates the light source, the light modulating device, and the projection optical system. In the projector, an opening that introduces air from the outside of the exterior housing into the inside thereof is formed in the exterior housing. The object to be cooled, a duct 613 connecting the opening to the object to be cooled, and a filter purifying the air introduced from the opening are provided inside the exterior housing. Cooling fans 614 and 615 that suck the air having been purified through the filter and send the air to the object to be cooled are provided in the duct 613. First sealing members 73 and 74 with which a gap is filled, are interposed between the cooling fans 614 and 615 and the duct 613. <P>COPYRIGHT: (C)2011,JPO&INPIT |
