Abstract
The invention provides a projector that can have a light source device, an optical device that modulates, in accordance with image information, beams emitted from the light source device to form an optical image, and an external case that accommodates the light source device and the optical device. The projector can enlarge and project the optical image formed by the optical device. The projector can include leg portions that are disposed so as to be extendable from and retractable to an outer peripheral surface of the external case to adjust the projection position of the enlarged and projected optical image, an intake opening formed in the surface of the external case disposed with the leg portions, and an intake fan that is disposed inside the external case near the intake opening and introduces cooling air from the outside of the external case. An intake surface of the intake fan can be disposed at an inclination with respect to the plane of the external case in which the intake opening is formed.
