CARTRIDGE INSTALLED WITH POSSIBILITY OF EXTRACTION INTO MAIN UNIT OF ELECTROPHOTORAPHIC IMAGE DEVICE, METHOD FOR ASSEMBLYING DRIVE TRANSMISSION DEVICE FOR PHOTOSENSITIVE DRUM AND ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE Russian patent published in 2021 - IPC G03G21/00 

FIELD: cartridges.

SUBSTANCE: invention relates to cartridges, installed with the possibility to remove to a main assembly of an electrophotographic image forming device comprising a rotating engaging part of the main assembly side. Cartridge is adapted to be removed outwardly from the main assembly of the device after being moved in a predetermined direction, essentially, perpendicular to the axis of rotation of the engaging part of the main assembly side. The cartridge contains a rotating element that carries out the transfer of the developer with rotation; a rotary transmittable rotational force receiving member provided at the end of said rotary member; moreover, the transmittable rotational force transmitting rotating member includes an encompassing portion in its interior space; connecting element. The connecting element includes a free end portion having at least one protrusion; a connecting part that is jointed with the rotating member receiving the transmitted rotational force and the part that is housed in the encompassing portion so that the axis of rotation of the connecting member is tilted relative to the axis of rotation of the rotating member receiving the transmitted rotational force; a through hole passing through the connecting part; a shaft passing through the body-size hole and capable of receiving the rotational force from the connecting member and supported by the rotating member receiving the transmitted rotational force to allow the connecting member to tilt relative to the shaft; an adjusting member attached to the rotating member receiving the transmitted rotational force; an adjusting shaft for preventing the shaft from disconnecting with the rotating member receiving the transmitted rotational force by contacting the opposite ends of the shaft.

EFFECT: ensured cartridge drive transmission structure, where disengagement of the connecting element is prevented without limiting the angle of inclination (rotation) of the connecting element by the inner edge of the open part fitted out with the flange.
