SUBUNIT ATTACHING STRUCTURE FOR IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To effectively reduce the push-in operation force of a subunit to a unit receiving part. SOLUTION: In this image forming device in which the subunit 3 is freely attachably/detachably pushed in and attached to the unit receiving part 2 formed in a device main body 1, a latch mechanism 4 with which latch members 4a and 4b to be respectively provided in the subunit 3 and the unit receiving part 2 in order to maintain the attaching state of both parts are engaged to be freely engaged and disengaged is provided between the subunit 3 and the unit receiving part 2, so that the peak point position (m) of the engagement reaction of the latch mechanism 4 at the operation time of attaching the subunit 3 is displaced to this side than the engagement completion position (n) (equivalent to the attachment completion position of the subunit 3) of the latch mechanism 4.
