|20150050048||TRANSMISSION DEVICE FOR PHOTOSENSITIVE DRUM - A transmission device for a photosensitive drum includes a sleeve, a transmission unit disposed in the sleeve and capable of moving and rotating at the same time, an elastic member, and a shell receiving the sleeve and the elastic member so that a relatively larger radius section and a relatively smaller radius section of the elastic member exert elastic force on the sleeve and the transmission unit, respectively. The transmission unit has two engagement blocks and a receiving space between them. Each engagement block has an inclined outer surface, an inner surface, an inclined top surface and an engagement concave connecting the inner and outer surfaces. The engagement concaves are opened toward opposite directions for engagement with two pillars of a drive member of an electronic image forming apparatus respectively. As a result, the transmission device can be connected with and separated from the drive member smoothly.||02-19-2015|
|20140140728||BEARING MECHANISM FOR PHOTOSENSITIVE DRUM - A bearing mechanism for connection with a photosensitive drum and an electronic imaging device includes a transmission member for coupling a rotary driving member of the electronic imaging device, a conductive piece at an inner portion of the transmission member, a conductive bar, and a spring member. The transmission member is synchronously rotatably mounted to the photosensitive drum and includes a through hole. The conductive bar is slidably mounted into the through hoe of the transmission member for electrically contacting a conductive shaft of the electronic imaging device. The spring member is electrically connected between the conductive piece and the conductive bar for providing a rebound force forcing the conductive bar to move away from the inner portion of the transmission member. In this way, the axial offset between the transmission member and the rotary driving member can be compensated.||05-22-2014|
|20100218631||QUICK-RELEASE GEAR ASSEMBLY - A quick-release gear assembly includes a retaining base having a base body and an elastic arm extending from the base body and provided at a distal end thereof with a first locating portion, and a gear having a gear body and a second locating portion located at the gear body and detachably engaged with the first locating portion of the retaining base for fastening the gear to the retaining base. Accordingly, the gear can be disassembled from the retaining base conveniently by disengaging the second locating portion of the gear from the first locating portion of the retaining base for the purpose of quick replacement of the gear.||09-02-2010|
|20100143001||TONER CARTRIDGE - A toner cartridge includes a housing, a wheel and a grating tube. The housing has a chamber for accommodation of toner, and an outlet in communication between the chamber and the outside. The wheel is rotatably connected the housing. The grating tube is coaxially connected to the wheel and defines several transparent areas and several opaque areas. The grating tube is made of transparent material and covered with several opaque layers defining the opaque areas such that the toner cartridge has the advantages of flexible application, being compatible with different types of image-forming apparatuses, and reducing manufacturing cost.||06-10-2010|
|20090097885||POWDER-DELIVERING DEVICE FOR TONER CARTRIDGE - A powder-delivering device includes a tapered shell received in a toner cartridge near an outlet of the toner cartridge. The tapered shell has a transection area becoming smaller gradually toward the outlet of the toner cartridge. The tapered shell has an outer surface having at least one projection or at least one recess. The projection of the tapered shell has a spiral or linear shape. The projection has an end, which is remote from the outlet of the toner cartridge, stopped against an inner wall of the toner cartridge. Thus, the powder-delivering device of the invention has simple structure and low product costs.||04-16-2009|
|20080279584||SUPPORTING APPARATUS FOR A PHOTOSENSITIVE DRUM - For supporting a cylindrical photosensitive drum, a high-precision high-strength supporting apparatus is disclosed to include a sleeve member and a shalt member. The sleeve member has an outer wall for attaching to the photosensitive drum, an inner wall within which an axial hole is defined, a first retaining portion positioned at the inner wall, and four locating ribs disposed inside the axial hole. The shaft member has an outer tube inserted into the axial hole of the sleeve member, a second retaining portion provided on the outer tube and engaged with the first retaining portion of the sleeve member, a connecting portion inwardly extending from the outer tube, an inner tube disposed at an inner end of the connecting portion, and four locating slot provided on the inner tube and engaged with the locating rib of the sleeve member.||11-13-2008|
|20080273899||TONER CARTRIDGE - A toner cartridge includes a container defining a central axis and a toner-guiding member. The container is provided at one end thereof with an opening having a radius. The toner-guiding member is provided with an annular connecting portion connected with the container, an outlet at one end thereof, a longitudinally-extending portion at the other end thereof extending into the container through the opening, an inlet formed on the longitudinally-extending portion, and a flexible scraping piece mounted on the longitudinally-extending portion and adjacent to the inlet. The scraping piece has a distal end defining with the central axis a distance longer than the radius of the opening, such that the toner in the container can be substantially fully discharged out of the toner cartridge so as to lower the residual quantity of toner in the toner cartridge.||11-06-2008|
|20080267670||CONTAINER FOR TONER CARTRIDGE - A container for a toner cartridge includes a hollow main body defining a longitudinal central axis. The main body has a first section near a rear end thereof, a second section near a front end thereof, a connecting section between the first and second sections, a longitudinal rib extending from the first section to the second section via the connecting section. The radii of cross sections of the first and second sections respectively gradually increase toward the front end of the main body. The longitudinal rib has a third guiding surface defining with the central axis a distance shorter than the radius of a cross section of the connecting section. The container can effectively move the toner accommodated inside the container from the rear end toward the front end. A mold for the container is easy to manufacture, resulting in cost reduction in manufacturing.||10-30-2008|
