OPTICAL SCANNER AND IMAGE FORMING APPARATUS WITH THE OPTICAL SCANNER MOUNTED THEREON

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive optical scanner or the like in which a scanning line curvature correction mechanism and a scanning line tilt correction mechanism can be independently adjusted and arranged in an optical housing in a simple structure. SOLUTION: A long-length lens assembly 50 is constituted by fitting and supporting a long lens 5 on a bracket 21 with a first to a third leaf springs 22 and 24, and the long lens assembly is supported at the supporting point 13c of the optical housing 13. The curvature of a scanning line of the long lens is adjusted by pressurizing the central part of the bracket with a curvature adjustment member 25. The tilt of the long lens is adjusted by rotating a driving motor 26. COPYRIGHT: (C)2006,JPO&NCIPI
