Title: Optical scanner and image forming apparatus
Inventor: NOMURA YUJIRO
IPC: B41J2/44
Filed: 2004-01-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical scanner in which the surface to be scanned is stably scanned with a light beam and to provide an image forming apparatus using the optical scanner.  <P>SOLUTION: A mirror driving means drives a deflection mirror face at a driving frequency fd which is higher than a resonance frequency and within an optical scanning possible band. Thus, the rocking amplitude of the deflection mirror face is reduced when the driving frequency fd is varied by Δ toward a high frequency side, a light beam deflected by the deflection mirror face passes through a light beam detection position A at a time t11, and passes through a light beam detection position B at a time t12. Namely, the scanning time becomes substantially equal to the scanning time PT before the driving frequency varies. In this way, even when the driving frequency of the deflection mirror face varies a little, the scanning time from the light beam detection position A to the light beam detection position B is kept substantially constant and the surface to be scanned is stably scanned with the light beam.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
