LASER SCANNING UNIT AND IMAGE FORMING DEVICE Russian patent published in 2025 - IPC B41J2/44 G02B26/10 

FIELD: image forming apparatus.

SUBSTANCE: laser scanning unit has a plurality of devices for emitting laser beams, a deflecting device and a plurality of optical scanning systems, having a main optical element and auxiliary optical elements. Each of the main optical element and auxiliary optical elements is provided with a bearing component for supporting each of the main optical element and the auxiliary optical elements, clamping component interacting with the bearing component for pressing each of the main optical element and the auxiliary optical element, and a bending adjustment mechanism for adjusting the bending degree of each of the main optical element and the auxiliary optical element, wherein the bearing component is provided with a support component. Difference of installation angles between the main optical element and the auxiliary optical element is equal to θn, minimum distance from the action point of the bend adjustment mechanism on the main optical element to the central point of the support component is Sk, and the minimum distance from the action point of the bend adjustment mechanism on the auxiliary optical element to the central point of the reference component is Sn, where .

EFFECT: simplified adjustment, higher accuracy of curve correction.
