ABSTRACT:
A light scanning device for scanning a scanned medium in a main scanning direction with a light beam has a detachable scanning unit having a reflecting mirror and a resonant light deflector. The scanning unit has a first adjusting mechanism for tilting the reflecting mirror about one axis to correct for a bow and an offset of a scanning line on the scanned medium in an auxiliary scanning direction substantially perpendicular to the main scanning direction, and a second adjusting mechanism for tilting the resonant light deflector about two axes to correct for a bow, a lean and an offset, respectively, of the scanning line on the scanned medium. When the resonant light deflector is to be replaced, the scanning unit is replaced with a new scanning unit which has already been adjusted. Therefore, the whole process of replacing the scanning unit can easily and quickly be carried out.
