Patent ID: 6935752

Claim:
An image projecting apparatus forming an image by projecting a light irradiated from a light source onto a digital micromirror panel, comprising: the digital micromirror panel configured such that a normal plane of a movable mirror surface of the digital micromirror panel, which is parallel with a longer side of the movable mirror surface, is parallel with an optical axis of the light source; a first reflective mirror configured to reflect the light from the light source at a predetermined angle; and a second reflective mirror configured to receive the light reflected from the first reflective mirror and to reflect the light onto the movable mirror surface of the digital micromirror panel, wherein the second reflective mirror is configured such that the light from the first reflective mirror is reflected from the second reflective mirror to be incident on the movable mirror surface of the digital micromirror panel, with an angle between the normal plane of the movable surface and the incident light being 1.5˜2.5 times greater than the angle at which the digital micromirror is tilted, and also with an angle between the orthographic projective line of the incident light and the longer side of the movable mirror surface being 40°-50°.
