  • Publication number: 20070264063
    Abstract: An automatic document feeder, for transferring a document through a scanning position three times, includes: a first transfer mechanism to reverse a given document via a reversing path, and transfer the same to a scanning position; a second transfer mechanism to transfer the given document from the scanning position to one of a switchback path and a document discharging part; a switchback mechanism to transfer the given document to a lay-by on the switchback path, and then transfer the given document towards the reversing path via a re-entry path; and a control unit to control the mechanisms so that a second original document passes through the scanning position a first time before a first original document passes through the scanning position a third time, and to pause travel of the second original document at the lay-by as the first original document is passed through the scanning position a third time.

  • Patent number: 7004464
    Abstract: An ADF (Automatic Document Feeder) for an image processing apparatus of the present invention includes a separating and feeding device for feeding one document from a stack of documents while separating the document from the others. A conveying device temporarily stops the document fed by the separating and feeding device at a position preceding a reading position and again conveys, on the elapse of a preselected period of time, the document toward the reading position. A controller controllably drives the separating and feeding device and conveying device. The controller drives the conveying device by controlling the time interval between the restart of conveyance of the preceding document and the restart of conveyance of the following document.
