PROBLEM TO BE SOLVED: To provide an image projector whose size is reduced by proper constitution. SOLUTION: Light irradiated by a projection section 102 and corresponding to an image is reflected by a half mirror 101 but a part of it is transmitted through the half mirror 101. A concave mirror 104 is arranged at a position where the transmitted light reaches. The transmitted light is reflected by the concave mirror 104. Since a reflecting surface of the concave mirror 104 is a curved surface, light reflected by the concave mirror 104 is converged in a narrow range. A horizontal plate 107 constituting an attenuation board 106 is arranged at a position where the light reflected by the concave mirror 104 is converged. COPYRIGHT: (C)2007,JPO&INPIT
