学系位置調整装置。[Claims for Utility Model Registration] Arranged in a staggered manner at a predetermined pitch SP in the main scanning direction parallel to the rotation axis of the photosensitive drum and a predetermined pitch LP in the sub-scanning direction perpendicular to the main scanning direction. In the optical system position adjustment device of an optical writing printer, which selectively opens and closes multiple microshafts to selectively transmit light from a light source and expose the surface of a photoreceptor drum, a plurality of microshafts arranged in a straight line are used. A light-receiving element consisting of cells is arranged at the same position as the exposure surface of the photoreceptor drum, and the angle θ formed by the arrangement direction of the cells of the light-receiving element and the arrangement direction of the microshutter is θ=tan −1. LP1.5S
The optical system is arranged at a position substantially defined by P, and the light receiving element is irradiated with the transmitted light of the microshutter, and the position of the optical system is adjusted according to the detection output of the light receiving element. Optical system position adjustment device for optical writing printers.
