Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To provide a simple straightening mechanism of a light beam scanner capable of straightening the curve of a scanning line on a surface to be scanned. SOLUTION: A light beam LB (LBc and LBe) passing through an inclined fθ lens is reflected and deflected by a deflector and made to pass through the fθ lens again.

The scanning line on the photoreceptor 30 is curved by the inclined fθ lens. When the plane mirror 28 is driven in an adjusting screw 40 and curved so that its reflection surface 28A is convex, the curve of the scanning line is straightened, so that the scanning line is straightened to be a straight line.  Thus, the curve of the scanning line is adjusted by a simple one-direction adjusting mechanism, only in the thrust direction of the screw 40.
