This invention is related to an image forming device including an optical scanning device which is able to adjust the irradiation from a beam to a vibrating mirror in a simpler means.
本发明涉及一种包含能够以更简单的方式调整光束对振动镜照射的光扫描装置的图像形成装置。
An analytical expression for spot moving speed on the former vibrating mirror of the polygonal mirror scanning system objective is derived from geometrical optical principle.
