Abstract
A projector having optical components, a power source unit, and a light source unit. The projector is capable of lowering its internal temperature utilizing: a first, second, and third fan () provided near the optical components for introducing external air from outside the projector to cool the optical components; and a fourth, fifth, and sixth exhaust fan (). The fourth fan () blows the air that was taken in by the first, second, and third fan () and has cooled the optical components, onto the light source unit to further cool the light source unit. The fifth and sixth exhaust fans () discharge the air that has cooled the light source unit and power supply unit out of the projector.
