Abstract

A light beam scanning system two-dimensionally scans a recording medium 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 for deflecting a light beam in a main scnning direction, an auxiliary scanning light deflector 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 disposed between the main and auxiliary scanning light deflectors. The recording medium is supported by a recording medium support and scanned with the light beam deflected by the main and auxiliary scanning light deflectors. The recording medium support includes an arcuate support surface having a center of curvature substantially aligned with the axis of angular movement of the auxiliary scanning light deflector.

Claims53

Dependent claims

A light beam scanning system for two-dimensionally scanning a recording medium with a light beam, comprising:

(i) a light beam source for emitting the light beam;
(ii) a main scanning light deflector for deflecting the light beam from said light beam source in a main scanning direction;
(iii) an auxiliary scanning light deflector angularly movable about an axis for deflecting the light beam in an auxiliary scanning direction which is substantially perpendicular to said main scanning direction;
(iv) an image-forming lens disposed between said main and auxiliary scanning light deflectors for passage therethrough of the light beam traveling from said main scanning light deflector to said auxiliary scanning light deflector;
and
(v) a recording medium support having a support surface for supporting the recording medium thereon to cause the recording medium to be scanned with the light beam deflected by said main and auxiliary scanning light deflectors, said support surface having an arcuate shape having a center of curvature substantially aligned with said axis of angular movement of said auxiliary scanning light deflector.
