A projector that includes: 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 projection-video-use video signal; 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 at least controls operation of the light-on/off unit and that of the recording medium reproduction unit. In the projector, the control section turns off the light source, and interrupts 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 turns on the light source, and starts reproduction by the recording medium reproduction unit 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.
