20140037336 | PHOTOSENSITIVE DRUM AND A PROCESS CARTRIDGE - A photosensitive drum includes a cylindrical photoreceptor, a drum gear located at one end of the photoreceptor, a drum shaft extending axially along the photoreceptor from one end of the drum gear for rotatably supporting the photoreceptor, and a projecting member extending longitudinally along the photoreceptor from an end surface of the drum shaft for coupling a twisted surface of a corresponding twisted triangular groove on a driving head of an imaging device. The projecting member, which is provided at one end of the photoreceptor, is operable to reciprocate along the longitudinal direction of the photoreceptor with respect to the photoreceptor. As a result, the photosensitive drum is prevented from being ejected from the driving head of the imaging device during force transmission between them, while maintaining a stable transmission of driving force between the photosensitive drum and the imaging device. A process cartridge carries the photosensitive drum. | 02-06-2014 |
20130136492 | PROCESS CARTRIDGE FOR AN IMAGING DEVICE - A cartridge that can be detachably installed within an imaging device, which includes a cartridge casing, a photosensitive drum driving assembly located on the casing, and a control mechanism for controlling extension and retraction of a force receiving head in the photosensitive drum driving assembly. The control mechanism includes a control rod, which can rotate around a pivot on the cartridge casing, and a elastic means mounted on the control rod. The cartridge of the invention uses a control mechanism to control extension and retraction of the force receiving head in the photosensitive drum driving assembly, and as a result when the cartridge is removed of the imaging device, the force receiving head does not become stuck by a driving head of the imaging device. | 05-30-2013 |
20120257906 | PROCESS CARTRIDGE - The present invention relates to a process cartridge, comprising a photosensitive drum driving component in conjunction with an image forming apparatus driving head, wherein said image forming apparatus driving head includes a twisted recess and said photosensitive drum driving component includes a drum gear provided at an end of a photosensitive drum and connected to the photosensitive drum, a drum shaft outwardly projected in an axis direction from an end of the drum gear for rotatably supporting said photosensitive drum during operation and a boss outwardly projected from an end surface of the drum shaft. A first teeth and a second teeth in a radial direction of the boss are provided on a side wall of said boss, wherein said first teeth is engaged with a twisted-section of the twisted recess in said image forming apparatus and said second teeth is engaged with an end surface edge of other twisted-sections of the twisted recess in said image forming apparatus. Thereby, the process cartridge according to this invention ensures an effectively and continuously transmitted driving force and contains a simple prepared photosensitive drum driving head, which will be less damaged even during long time operation. | 10-11-2012 |
