Abstract
A projector includes a sirocco fanas an exhaust fan arranged oppositely to an exhaust holeB formed on an exterior caseto suck air inside the exterior caseand to discharge the air to the outside via the exhaust holeB. The sirocco fanis arranged such that a suction side thereof is along a plane orthogonal to an optical path plane defined by a light source device, an optical modulator and a projection optical device of a device body of the projector. Further, the sirocco fanis arranged such that a discharge holeA is inclined in a fan rotation direction to discharge the sucked air substantially to the center of an end surface with the exhaust holeB formed in a thickness direction. Accordingly, such projector is provided that can enhance an exhaust efficiency by sucking the air of the inside effectively without the rotation number of the exhaust fan increased, and also can reduce the thickness thereof.
