摘要：
An optical scan apparatus is configured to include a light source emitting a light beam; a vibration mirror deflecting the light beam emitted from the light source to scan a scan area; a drive unit driving the vibration mirror; and an optical imaging system focusing the light beam deflected by the vibration mirror on a predetermined focus position, and having optical power to correct a displacement of the focus position which occurs due to a deformation of the vibration mirror caused by its own vibration.
