Projector

A projector comprising:

• a light source;
• a light modulation device which modulates a light emitted from the light source and forms image light;
• a projection device which magnifies and projects the image light;
• and
• an exterior casing,
• wherein:
• on a light exiting surface for the image light of the exterior casing, a first opening is formed and a projection direction change unit which opens and closes the first opening is provided,
• the projection direction change unit has:
• a cover which has a second opening for passing the image light from the projection device and which is provided rotatably in an off-plane direction with respect to the light exiting surface and thus opens and closes the first opening;
• a shutter which is movably provided along an inner surface of the cover and thus opens and closes the second opening;
• and
• a reflection mirror which is provided on an inner surface of the shutter and reflects the image light from the projection device,
• a second lock mechanism which regulates movement of the shutter in a second state where the first opening is opened by the cover and the second opening is closed by the shutter, and which cancels the regulation in a third state where the first opening is closed by the cover and the second opening is closed by the shutter, and
• the second lock mechanism has:
• an energizing member provided on the inner surface of the cover;
• a stopper which is connected to the energizing member and regulates movement of the shutter in the second state;
• and
• a stopper canceling pawl which protrudes inward of the first opening from a peripheral edge of the first opening, and
• in the third state, the stopper canceling pawl presses the stopper toward the cover against an energizing force of the energizing member and thus cancels the regulation.
