Abstract
A light is emitted from a light emitting element toward the other surface in a thickness direction of a scanning mirror which can be angularly displaced about an axial line. At least either one of a first light receiving portion and a second light receiving portion receives a light which is emitted from the light emitting element and reflected by a reflecting mirror. The first light receiving portion, the second light receiving portion, and the signal output section produce an electronic signal containing position information which indicates a position which is irradiated with the above-mentioned light. This position information indicates an amount of angular displacement of the scanning mirror. On the basis of this position information, a driving section scans the scanning mirror so that the predetermined irradiation position can be irradiated with a light emitted from a first light source.
