Title:
OPTICAL SCANNING DEVICE AND IMAGE FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/181208
Kind Code:
A1
Abstract:
An optical scanning device (15) is provided with: a reference light guide part (50) that guides light that has passed through a reference lens (52) to a photosensitive drum (20); a subordinate light guide part (40) that guides light that has passed through a subordinate lens (42) to the photosensitive drum (20); a reference holding structure (53) having a reference receptor part (55) provided so as to be contactable with the reference lens (52) in a bent state; and a subordinate receptor part (45) provided so as to be contactable with the subordinate lens (42) in a bent state. The reference lens (52) and the subordinate lens (42) are disposed such that the bending direction of the reference lens (52) with respect to the reference receptor part (55) coincides with the bending direction of the subordinate lens (42) with respect to the subordinate receptor part (45). The absolute value of the shortest distance (B) between the subordinate receptor part (45) and the subordinate lens (42) is set to be greater than or equal to the absolute value of the shortest distance between the reference receptor part (55) and the reference lens (52) when it is assumed that the reference lens (52) and the subordinate lens (42) are not bent.
