  • Patent number: 8730531
    Abstract: An automatic document feeding scanning device including an automatic document feeder, a flatbed scanner and a power switching mechanism is provided. The automatic document feeder has a pickup arm and a feeding gear, the flatbed scanner has a scanning module and a scanning gear. When the scanning module is moved and the movement of the scanning module is obstructed to enable the scanning module to take a first reacting force, the power switching mechanism is disengaged from the scanning gear in response to the first reacting force and transfers a driving power to the automatic document feeder. When the pickup arm is swung and the swing of the pickup arm is obstructed to enable the pickup arm to take a second reacting force, the power switching mechanism is disengaged from the feeding gear in response to the second reacting force and transfers the driving power to the flatbed scanner.

  • Patent number: 8550447
    Abstract: An automatic document feeder includes a document input tray, a document discharge tray, a pushing member, and an elastic element. The document discharge tray is disposed under the document input tray. The pushing member is disposed on the document input tray. By pushing the pushing member, the pushing member is swung relative to the document input tray. The elastic element is contacted with the pushing member and the document input tray. The elastic element provides an elastic force to the pushing member. When the pushing member is not pushed, the pushing member is returned to an original position in response to the elastic force. By pushing the pushing member to allow the pushing member to be swung relative to the document input tray, the document discharge tray is exposed through the document input tray. Consequently, the paper sheet can be easily removed from the document discharge tray.
