Patent ID: 8616707

Claim:
A projector comprising: a housing; a spatial light modulation device modulating a projected light according to an image signal; a dustproof filter capturing dust; a partitioning wall separating inside of the housing into a first area and a second area, the partitioning wall completely partitioning the second area from the first area and having a clearance through which the cooling air flows; a first intake fan introducing cooling air from outside of the housing via the dustproof filter into the first area; and an exhaust fan which discharges cooling air to outside the housing, wherein, the first area accommodates a first cooling target including the spatial light modulation device, the second area accommodates a second cooling target including a circuit board, and the cooling air introduced into the first area via the dustproof filter and cools the first cooling target, and a portion of the cooling air flows through the clearance and cools the second cooling target in the second area, while another portion of the cooling air is discharged from the first area to the outside of the housing by the exhaust fan.
