|20150177683||PROCESS CARTRIDGE - The invention relates to a process cartridge, which comprises a process cartridge housing, a photosensitive member, a driving force receiving opening, a retractable mechanism and a control mechanism, wherein the photosensitive member is arranged inside the process cartridge housing; the driving force receiving opening is connected with the photosensitive member and provides a driving force for the photosensitive member; the retractable mechanism allows the driving force receiving opening to extend or retract in the axial direction of the photosensitive member; and the control mechanism controls the extension and retraction of the retractable mechanism.||06-25-2015|
|20140119775||DEVELOPER CARTRIDGE WITH COUNTING MECHANISM - The invention provides a developer cartridge with a counting mechanism. The developer cartridge comprises a developer and the counting mechanism, wherein the counting mechanism is provided with protrusions which come in contact with a contact lever on an electronic photographing device so as to count the developer cartridge; and each protrusion has a first position and a second position in the direction perpendicular to a side wall of the developer cartridge, and is, in the first position, in contact with the contact lever, but is not, in the second position, in contact with the contact lever. The working principle of the developer cartridge adopting the counting mechanism is greatly different from the prior art. Therefore, the structure of the counting mechanism of the developer cartridge is simpler and more convenient and reliable; the production precision and the production cost are reduced; and the market competitiveness of the developer cartridge is improved.||05-01-2014|
|20130177333||IMAGE FORMING DEVICE, PROCESS CARTRIDGE ENGAGED WITH THE SAME AND METHOD FOR FIRMLY POSITIONING PROCESS CARTRIDGE IN IMAGE FORMING DEVICE - The invention provides an image forming device, a process cartridge engaged with the same and a method for firmly positioning the process cartridge in the image forming device. The image forming device, comprising a main frame and a main frame driving gear, wherein a guide rail is respectively arranged on the left and right sides of the inside of said main frame; an installation section is arranged at the tail end of each guide rail; and said installation section and said guide rail approximately form a barb. Lugs formed at both ends of a housing of the process cartridge are driven by a radial component of driving force of the image forming device to the process cartridge to always closely lean against the walls of the installation sections at the tail ends of the guide rails when the process cartridge is in the operating state in the image forming device.||07-11-2013|
|20120087699||TONER CARTRIDGE WITH A LOCK MECHANISM - The invention relates to a toner cartridge with a locking mechanism, including a body provided with a top cover and used for receiving a developer, wherein the locking and unlocking mechanism used for locking the toner cartridge into an image forming apparatus is arranged on the body. The locking mechanism includes a handle hinged with the top cover, a gear fixedly connected with the handle, a locking lever capable of reciprocating and a torsion spring used for realizing the automatic reset of the handle. A rack engaged with the gear is arranged on the locking lever. Moreover, the handle is driven to be close to the top cover under the action of a torque force of the torsion spring under the locking state, and the gear is engaged with the rack to drive the locking lever to be extended out of the top cover so as to lock the toner cartridge. When the handle is under the unlocking state by overcoming the torque force of the torsion spring under the action of an external force, the gear and the rack are operated to drive the locking lever to be retracted into the top cover so as to unlock the toner cartridge. Unlocking and locking can be realized through a tensile force of a human hand and the reset of the torsion spring.||04-12-2012|
