|20070211326||Optical scanning apparatus, optical writing apparatus, and image forming apparatus|
A scanning optical system condensing a beam deflected by an optical deflector so as to form a beam spot on a surface to be scanned, comprises two lenses. A lens on the side of optical deflector has a negative refracting power in sub-scanning direction. A lens on the sid...
|20070206261||OPTICAL SCANNER AND IMAGE FORMING APPARATUS|
An optical scanner includes a single deflector to optically scan a plurality of target surfaces. The deflector is shared by all the beams from a plurality of light sources. The optical scanner includes photodetectors arranged to receive the deflected beams deflected. Th...
|20060152788||Optical scanner and image forming apparatus including optical scanner|
In an optical scanner, a scanning and imaging optical system is fitted to an optical housing. The optical housing includes a seat that has a holding surface for holding a condenser lens. A ridge at each of opposite ends on the holding surface of the seat is linear in th...
