    • 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.
    • 一种扫描光学系统,其中光束被按照预定方向旋转的多面镜的每个反射面依次反射,以将其转换成沿单一方向重复移动的扫描光束,以扫描 所述光学系统设置有用于沿着反射表面的旋转运动的方向沿着单个方向移动入射在反射表面上的光束并且以与多面镜的旋转同步的重复方式移动光学装置 使得光束可以不断地投影到多面镜的每个反射表面的有效反射区域上。
