  • Patent number: 7441763
    Abstract: A document feeder for multifunction printers or scanners offers high reliability and speedy paper-picking, -separating and -feeding functions. It comprises a picking module, a separating module and a feeding module. Since the three modules take turns to deliver paper, the paper can be picked at a lower speed, separated at a medium speed and then fed at a high speed. In addition, the separating module comprises a clutch. When the paper was fed by the feeding module, the clutch is activated to provide an interval between papers and to prevent papers from plucking.

  • Publication number: 20080043294
    Abstract: A double-side scanning mechanism for capturing images of a paper having two pages includes a second transparent element disposed corresponding to an outer side of a first transparent element and parallel to the first transparent element. A paper conveying device conveys a paper to pass between the first and the second transparent elements with a first page facing the first transparent element. The paper is flipped and passes over the outer side of the second transparent element with a second page facing the second transparent element. An image scanning module is disposed corresponding to an inner side of the first transparent element, for capturing the image of the first page when the paper passes between the first and the second transparent elements, and capturing the image of the second page when the paper passes over an outer side of the second transparent element.

  • Patent number: 6988722
    Abstract: A paper pickup mechanism located on one side of a feeding paper tray consists of a pickup roller, a plurality of gears and a plurality of linkage bars to form a highly free mechanism that drives the pickup roller rotating in the paper feeding direction and generating a torque to enable the pickup roller exerting a force on the top paper of the paper tray and provide an automatic compensating paper pickup force. By rearranging the structural locations of the elements, fewer gears are required to transmit the driving power, and energy loss and noise generation are reduced.
