Abstract
An optical scanner comprises a plurality of light sources, a deflection/scan means for deflecting light beams emitted from the light sources and causing them to scan, and an imaging optical system for focussing light beams coming from the deflection/scan means on an imaging plane. The plurality of light sources are secured by a plurality of light source holders which are by turn secured on a lateral wall of an optical cabinet accommodating the light sources and the deflection/scan means. One or more of the light source holders secure two light sources and are rotatably secured on the lateral wall so that the vertical distance separating the respective light beams emitted from the two light sources can be regulated.
