Simple Optical Scanning Apparatus using Multi-refrection inside Optical Block

Abstract

A optical scanning apparatus for use with a compact lazer printer has been developed. This scanning apparatus has optical glass block, instead of an fθ lens. To select a ratio (ratio of optical path length) of the whole length of an optical path, we can revise curvature of field. And, the scanning apparatus has electrical circuit for revising distortion. As a result, the scanning apparatus has been obtained with a print line of 11 inches and resolution of 400 dpi.
