Claims

[Claims for Utility Model Registration] 1. A scan device that reflects and scans a light beam emitted from a light source by a mirror to project a light image onto a light receiving section, wherein the mirror is configured to scan in a direction perpendicular to the scanning direction of the light beam. A scan device characterized in that it is held by a pair of extending torsion bars. 2. The scan device according to claim 1, wherein the mirror and the torsion bar are integrally formed from a single single crystal silicon thin plate.
