Disclosed is an image projecting apparatus having two reflective mirrors. In an image projecting apparatus which forms a desired image on a digital micromirror panel (DMD) by projecting a ray of light from a light source thereonto, the surface parallel with the longer side of the movable mirror surface of the DMD panel and vertical to the movable mirror surface is parallel with the optical axis of the light source. The first reflective mirror reflects the ray of light from the light source at a predetermined angle, and the second reflective mirror is arranged to face the first reflective mirror and reflect the reflective light from the first reflective mirror to fall incident on the movable mirror surface of the DMD panel. The distance from the center of the DMD panel to the optical axis is minimized, and as a result, the overall height of the image projecting apparatus is reduced.
