<p>A thin type projector is provided to minimize the space of an optical system through the new optical system, thereby reducing the thickness of a projector. A lens shift control screw is exposed to a side of a housing and moves a projection lens member. An air suction hole is formed at the side and lower portions of the housing, and an air discharge hole is formed at the upper portion of the housing. A light source is positioned at the lower portion of the air discharge hole. A sensor is installed within the housing, senses the inclination of the housing and cuts off the power of an illumination member when the inclination of the housing is above the reference point.</p> |
