ABSTRACT:
A multi-beam scanning optical device uses optical fibers to transmit the laser fluxes from the semiconductor lasers. The optical fibers are arranged such that point light sources formed at respective exit ends of the optical fibers are linearly aligned. The exit light fluxes from the optical fibers are deflected by a polygon mirror and converged on an image surface to form a line of beam spots, which forms plurality of scanning lines per scan.
In order to adjust the angle of the line of beam spots, the exit end portions of the optical fibers is fixed to a fiber alignment block such that the exit end surfaces of said optical fiber are linearly aligned on an alignment line. Further, the fiber alignment block is fixed to a cylindrical member which is rotatably supported by a supporting member. Accordingly, the angle of the line of beam spots can be easily adjusted by rotating the cylindrical member.
