    • As a light beam of a scanning optical system unit is adjusted in the state where the scanning optical system unit is assembled, its adjustment work and the assembly work of the scanning optical system are prevented from being useless. Thus, a scanning optical system adjusting device which can adjust the scanning optical system quickly and at a low cost is to be provided. A scanning optical system adjusting device according to the invention includes a static angle control unit configured to maintain a rotation angle of a rotary polygon mirror in the assembly unit of the scanning optical system at a predetermined angle and make the rotary polygon mirror static there, and a light beam parameter measuring unit configured to measure a predetermined parameter of a light beam reflected by the rotary polygon mirror maintained at the predetermined angle by the static angle control unit.
    • 由于在组装扫描光学系统单元的状态下调整扫描光学系统单元的光束,所以防止其调整工作和扫描光学系统的组装工作变得无用。 因此,可以提供能够快速且低成本地调整扫描光学系统的扫描光学系统调整装置。 根据本发明的扫描光学系统调节装置包括静态角度控制单元,其构造成将扫描光学系统的组装单元中的旋转多面镜的旋转角度保持在预定角度,并使旋转多面体镜静止, 光束参数测量单元,被配置为测量由所述静态角度控制单元维持在所述预定角度的由所述旋转多面镜反射的光束的预定参数。
