Abstract
An exhaust sirocco fan exhausts the air inside the projector outside. An inlet of the exhaust sirocco fan is disposed along the plane orthogonal to the optical path plane formed by the optical unit, i.e. along the thickness direction of the projector. In other words, the optical unit or the exhaust sirocco fan need not be disposed in the thickness direction of the projector in an overlapping manner. Therefore, by efficiently sucking the inside air, the exhaust efficiency can be enhanced and calmness can be ensured in the projector.
