Projector

A projector comprising:

• a light source;
• a light modulating device that forms a light image by modulating a light beam projected from the light source in response to image information;
• a projection lens that projects the formed light image;
• and
• a chassis that houses the light source, the light modulating device, and the projection lens therein, wherein
• the chassis including
• a lens cover which is provided to be slidable relative to the chassis and which covers a projection aperture of the projection lens by sliding in one direction and exposing the projection aperture by sliding in the opposite direction,
• a detecting section including a light emitting portion which projects the light beam, and a light receiving portion that receives the light beam projected from the light emitting portion,
• the detecting section detects the opened state or the closed state of the lens cover depending on the absence or presence of the light beam received by the light receiving portion, and the light emitting portion and the light receiving portion are disposed so that the optical path of the light beam projected from the light emitting portion and inputted to the light receiving portion intersects a slide direction of the lens cover, and
• a light shielding portion shielding the light beam inputted from the light emitting portion to the light receiving portion is provided in the lens cover, and the light shielding portion is formed in a predetermined width in the slide direction of the lens cover.
