<p>Disclosed is a mirror that has a mirror surface of which orientation is variable, and that can be miniaturized at a low cost. The mirror includes an actuator for changing the orientation of the mirror surface by swiveling the mirror surface around axes parallel to the mirror surface, an interlocking member for changing its orientation in conjunction with the mirror surface, so as to face in the same direction as that of the mirror surface, one or more slide blocks being urged toward the interlocking member to thereby move in a direction substantially perpendicular to the mirror surface and in proportion to a swivel amount of the mirror surface, upon swivel of the interlocking member, and a swivel amount detector for detecting the swivel amount of the mirror surface, based on the moving amounts of the slide blocks.</p> |
