ROTARY FORCE TRANSMITTING COMPONENT Russian patent published in 2012 - IPC G03G21/18 

FIELD: physics.

SUBSTANCE: present invention relates to a device which transmits a rotary force for an electrophotographic process cartridge, an electrophotographic image-forming device, in which a process cartridge can be installed with possibility of its replacement, and an electrophotographic photosensitive drum unit. The device for the electrophotographic photosensitive drum has a connecting element engaged with the photosensitive drum, which is removed from the main unit in the direction of removal by re-displacement. When the photosensitive drum which is engaged with the connecting element is removed from the main unit in the direction of removal, the connecting element can turn such that the side which receives the rotary force of part of the axle lies before the side which transmits the rotary force of part of the axle relative the direction of removal. The connecting element can be disengaged from the engaging part of the main unit by re-displacement.

EFFECT: design of a device which includes a connecting element capable of transmitting a rotary force, which can be turned and removed from the main unit in the direction of removal.
