Abstract
An image projecting apparatus includes a projecting optical system having a curved reflection surface on a side closest to a screen on an optical path thereof, a first plane mirror for reflecting the image light emitted from the projecting optical system, a second plane mirror for reflecting the image light reflected by the first plane mirror, a first light shielding member arranged between the reflection type optical element and the second plane mirror, and a second light shielding member arranged between the first plane mirror and the screen.
Claims24
An image projecting apparatus comprising:
- a projecting optical system for emitting an image light to a screen, including a reflection type optical element having a curved reflection surface on a side closest to the screen on an optical path thereof;
- a first plane mirror for reflecting the image light emitted from the projecting optical system so as to lead the image light to the screen;
- a second plane mirror arranged on an optical path on the screen side of the first plane mirror for reflecting the image light reflected by the first plane mirror;
- and
- a light shielding member arranged between the reflection type optical element and the second plane mirror for shielding a light unnecessary for an image projection.
