PROJECTOR

摘要

A projector for projecting an image includes a light source that outputs light; a reflecting member that reflects the light from the light source; and a diaphragm member with an aperture that restricts a range of flux of either an incident light incident to the reflecting member or a reflected light reflected by the reflecting member. The aperture may penetrate through the diaphragm member along a direction of thickness of the diaphragm member. The diaphragm member may be arranged so as to not block the other of the incident light or the reflected light, and a direction perpendicular to the direction of thickness may be oblique with respect to an optical path of either the incident light or the reflected light.

1. A projector for projecting an image comprising:
a light source that outputs light; a reflecting member that reflects the light from the light source; and a diaphragm member having an aperture that restricts a range of flux of either an incident light incident to the reflecting member or a reflected light reflected by the reflecting member, wherein the aperture penetrates through the diaphragm member along a direction of thickness of the diaphragm member, the diaphragm member is arranged so as to not block the other of the incident light or the reflected light, and a direction perpendicular to the direction of thickness is oblique with respect to an optical path of either the incident light or the reflected light.
