Method and apparatus for image read-out and reproduction, and multi-semiconductor-laser light source device for the same.

摘要

An image read-out and reproducing method comprises the steps of conveying an image storage sheet, on which an image has been recorded, or a recording sheet, on which an image is to be reproduced, in a sub-scanning direction by a single sub-scanning system, and reading out the image from the image storage sheet by scanning the image storage sheet with read-out light in a main scanning direction and detecting the light emitted from the image storage sheet which is being scanned. An image is reproduced on the recording sheet by scanning the recording sheet with reproducing light modulated in accordance with the image, which has been read out, in a main scanning direction. Laser beams produced by a plurality of semiconductor lasers are combined, and the combined laser beams are utilized as the read-out light. Only one or some of a plurality of the semiconductor lasers are operated at the time of image reproduction, and the laser beams emitted thereby are modulated and utilized as the reproducing light.
