Abstract
A light beam scanning apparatus includes a laser device for emitting a laser beam, a deflector for periodically deflecting the laser beam thereby causing the laser beam to scan an object to be scanned, which is being moved in a predetermined direction, across a varyingly set scanning width. The scanning width is set in accordance with the size of the object to be scanned and the moving speed of the object is changed depending on the particular scanning width.
