Claim:
A projector, comprising: a light source; a light-on/off unit that turns on or off the light source; a recording medium reproduction unit that reproduces information recorded on a recording medium, and outputs a video signal; a video signal processing section that converts the video signal provided by the recording medium reproduction unit, and generates a video signal for a projection video image; a light modulation unit that modulates a light coming from the light source based on the video signal generated by the video signal processing section, and emits a resulting video light; a projection system that includes a projection lens, and magnifies and projects the video light coming from the light modulation unit; a lens cover that opens and closes the front of the projection lens; a lens cover open/close detection sensor that detects an open/close state of the lens cover; and a control section that controls operation of the light-on/off unit and that of the recording medium reproduction unit, the control section being configured to: (i) turn off the light source, and interrupt reproduction by the recording medium reproduction unit, when the lens cover open/close detection sensor detects a state change of the lens cover from open to close, and (ii) turn on the light source, and start reproduction by the recording medium reproduction unit (a) after a lapse of predetermined time after the light source is turned on and (b) in accordance with predetermined requirements, when the lens cover open/close detection sensor detects a state change of the lens cover from close to open.
