ABSTRACT:
A scanner scans the scan subject by means of utilizing a rotative movement of a rotatable movable member for rotatably moving on a predetermined rotation axis. A scan mirror is supported by a single support axis. A rotary power of drive motors is converted into a reciprocating motion by crank mechanisms to rotatively move the scan mirror. A rotary angle of the scan mirror is detected by utilizing a principle of an interferometer.
