A light beam scanning system two-dimensionally scans a recording medium (5) with a light beam to record image information on or read out recorded image information from a recording medium such as a stimulable phosphor sheet. The light beam scanning system includes a main scanning light deflector (3) for deflecting a light beam in a main scanning direction, an auxiliary scanning light deflector (10) angularly movable about an axis for deflecting the light beam in an auxiliary scanning direction normal to the main scanning direction, and an image-forming lens (4) disposed between the main (3) and auxiliary (10) scanning light deflectors. The recording medium (5) is supported by a recording medium support (11) and scanned with the light beam deflected by the main and auxiliary scanning light deflectors. The recording medium support includes an arcuate support surface (11a) having a center of curvature substantially aligned with the axis of angular movement of the auxiliary scanning light deflector (10).The recording medium support is also provided with shifter means (23,28,30) for shifting said recording medium (5) in said main scanning direction on said support surface. |
