ABSTRACT:
A reading light exposure system scans an image recording medium with a reading light beam. The reading light exposure system includes a line source emitting the reading light beam, an optical means which converges the reading light beam emitted from the line source in a direction perpendicular to the longitudinal direction of the line source, and a pinhole array having a number of pinholes which limit the angle of divergence of the reading light beam in the longitudinal direction of the line source with respect to the optical axis of the optical means. The length of each of the pinholes in the direction perpendicular to the longitudinal direction of the line source is larger than the length thereof in the longitudinal direction of the line source.
