CARTRIDGE AND DRUM UNIT FOR ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE Russian patent published in 2020 - IPC G03G21/18 

Abstract RU 2727791 C1

FIELD: image forming devices.

SUBSTANCE: present invention relates to a cartridge and a drum unit used for an electrophotographic type device for image forming, such as a laser printer. Disclosed cartridge is configured to be mounted in the main assembly of the electrophotographic image forming device, wherein cartridge comprises rotary connecting element, wherein main assembly includes rotating part for contact interaction, intended for contact interaction with said connecting element, and guide for connecting element located further downstream relative to rotation axis of contact interaction part with respect to installation direction of said cartridge and intended for contacting with said connecting element, a contact interaction element turned relative to the axis of rotation to direct said connecting member so that it is parallel to the axis of rotation of the contact interaction part, wherein said cartridge is configured to be installed in the main assembly in the installation direction, substantially perpendicular to the axis of rotation of the contact interaction part, wherein said cartridge comprises: a frame, a rotatable developer transfer member and a rotary force-receiving member for receiving a rotary force to be transmitted to said rotary member, wherein said connecting member includes a free end portion having a force receiving portion configured to receive a rotating force from the contact interaction portion, and a connecting portion having a force transmitting portion for transmitting a rotary force received by said sensing portion, said force sensing element, wherein said frame includes: a part with an aperture designed to make available said free end portion to act on the outside of said frame, and a receiving part made downstream relative to said portion with an opening in relation to the installation direction and intended to receive said connecting member when said connecting member is inclined to the downstream side relative to the mounting direction, and to receive said guide for connecting element, in contact interaction of said connecting element with part for contact interaction, and when it is parallel to rotation axis of part for contact interaction.

EFFECT: technical result consists in the realization of the purpose, as well as in the elimination of the shortcomings of the analogues of the prior generation of equipment.
