Abstract
A light beam scanner comprises a light beam generating unit for generating a light beam, a first scanning unit for guiding the light beam in a first scanning direction, a second scanning unit composed of a deflection prism for guiding the light beam in a second scanning direction that is different from the first scanning direction, and an object lens. The second scanning unit is movable in an optical direction in parallel with an optical axis or turnable around the optical axis, so that the light beam entering the second scanning unit may be deflected in any direction when exiting from the second scanning unit.
