Cover Movement Mechanism, and Image Forming Apparatus Provided with the Cover Movement Mechanism

摘要

A cover movement mechanism has a cover, a base part, a holding part configured to contact the cover in a first opened state in which the cover is rotated to open by a first angle with respect to a closed state, thereby holding the cover in the first opened state, two shafts having a common axis and provided to one of the cover and the base part, two bearings configured to receive the two shafts and provided to other one of the cover and the base part, and a releasing mechanism configured to allow at least one of the two shafts to be released from corresponding one of the two bearings when the cover is in a second state in which the cover is rotated to open by a second angle that is smaller than the first angle and an opposing force preventing a rotation of cover acts on the cover.

1. A cover movement mechanism, comprising:
a cover configured to rotate; a base part to which the cover is rotatably attached; a holding part configured to contact the cover when the cover is in a first opened state in which the cover is rotated to open by a first angle with respect to a closed state of the cover, thereby holding the cover in the first opened state; two shafts having a common axis and provided to one of the cover and the base part; two bearings configured to receive the two shafts and provided to other one of the cover and the base part; and a releasing mechanism configured to allow at least one of the two shafts to be released from corresponding one of the two bearings when the cover is in a second state in which the cover is rotated to open by a second angle that is smaller than the first angle and an opposing force preventing a rotation of cover acts on the cover.
