  • Patent number: 8548353
    Abstract: A developer cartridge is provided, which includes a toner cartridge, a developer stirring device located in the toner cartridge, a supply roller for supplying a developer to a developer roller, a developer roller for developing an electrostatic latent image on a photoconductor, and a power receptor for driving only one of gear sets of the above means to receive a power. The power receptor is rotatably fixed at two or more predetermined positions. An initial position of the power receptor is a power receiving position. A power receptor moving device includes a press block, a baffle block, a spring, and a torsion spring. The power receptor moving device is controlled by the press block. When the press block of the power receptor moving device is pressed downwards, the power receptor is rotated to another power receiving position due to the action of the torsion spring. The present invention is applicable to various types of machines.

  • Patent number: 7891770
    Abstract: A separate light-emitting ink cartridge including an ink container, an ink supply port, a shelf, a chip, a first joint portion, a second joint portion, a support component, and a light display portion is provided. The ink container and the shelf are independent workpiece respectively, and are detachably assembled together. The ink container has an ink storage chamber, and the ink supply port is disposed at the bottom of the ink container to supply ink accommodated in the ink container to an inkjet head. The chip, the first joint portion, the second joint portion, the support component, and the light display portion are disposed on the shelf. The separate light-emitting cartridge reduces the printing cost for users, and is environment friendly. Moreover, the structure of the separate light-emitting cartridge is simple and can be assembled conveniently.

  • Publication number: 20060232649
    Abstract: An ink cartridge for an inkjet printer includes a top cover, a bottom wall, a handle, an ink chamber, an air inlet, an ink supply port. The air inlet is disposed at the top of the ink chamber, such that the ink chamber is communicated with the atmosphere. A labyrinth capillary is disposed at the side surface of the bottom wall, with one end in communication with the bottom portion of the ink chamber and the other end in communication with the cavity for accommodating elongated fiber bundles. The ink supply port is disposed at the bottom of the cavity for accommodating elongated fiber bundles, and the elongated fiber bundles are accommodated in the cavity. The present invention has the following advantages of greatly reducing the residual ink, improving the printing yield, and reducing the manufacturing cost; reducing the waste, thereby benefiting for environment protection; and accomplishing the mass production, thereby enhancing the qualification rate.
