Patent ID: 8485670

Claim:
A projector apparatus that projects an image to a projected surface by illuminating an image forming element using light from a light source, the projector apparatus comprising: an apparatus casing that contains the light source and the image forming element; an air filter receiving portion that is provided in the apparatus casing and includes an air intake through which air is drawn; a plurality of air filters that have substantially the same area as an opening area of the air intake and are disposed opposite each other so as to face each other in the air filter receiving portion; a cooling fan that causes air to flow into the projector apparatus through the air intake by drawing air therearound and causes the air to pass through the plurality of air filters before blowing the air onto the light source and the image forming element to dissipate heat therefrom; a first air channel that directs a portion of the air flowing into the projector apparatus through the air intake to a front air filter that is positioned close to the air intake among the plurality of air filters and directs the air to the cooling fan by causing the air to pass through the front air filter; and a second air channel that directs the remaining portion of the air to a rear air filter that is positioned away from the air intake and directs the air to the cooling fan by causing the air to pass through the rear air filter.
