ABSTRACT:
A scanning optical system of a type wherein a light beam is sequentially reflected by each of the reflection surfaces of a polygonal mirror rotating in a predetermined direction to convert it to a scanning light beam which moves repetitively in a single direction to scan the surface of an object to be scanned, the optical system being provided with means for moving the light beam incident on the reflection surface in a single direction along the direction of the rotating movement of the reflection surfaces and in a repetitive manner in synchronism with rotation of the polygonal mirror so that the light beam may be constantly projected onto an effective reflection region of each reflection surface of the polygonal mirror.
