  • Automatic document feeder
    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.
