  • Patent number: 7540485
    Abstract: A paper feeding apparatus including a paper pickup roller assembly, a paper conveying roller assembly, a one-way driving assembly, and a reverse driving assembly is provided. The one-way driving and the reverse driving assembly are connected to a driving device, such as a motor, wherein the one-way driving assembly is engaged with the paper pickup roller assembly only in one direction to drive the paper pickup roller assembly forward as the driving device rotates forward and stop driving the paper pickup roller assembly as the driving device rotates backward, and the reverse driving assembly is provided for driving the paper conveying roller assembly to constantly rotate forward for conveying the paper sheet to move forward no matter whether the driving device rotates forward or backward.

  • 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.

  • Publication number: 20070296138
    Abstract: The present invention provides an object-feeding system. The feeding system includes an object feeder and a pickup roller. The object feeder includes an object separating ramp and a tray part. The object separating ramp is placed along an object feeding direction. The tray part is for loading at least an object to be fed, and the tray part includes a main body and a protruding portion sticking out from the main body and connected to the object separating ramp, wherein the protruding portion and the main body constitute a hollow part. The pickup roller is for feeding the object by rolling, wherein the hollow and the pickup roller separately locate two sides of the object and the pickup roller locates the hollow place above.
