Abstract: An auto document feeding device causes an original document passing through an OUT path and an original document passing through an IN path to flow together with overlap a trailing edge of a preceding original document and a leading edge of a following original document. Before the original documents reach to a READ document glass, the auto document feeding device comprises a separating unit configured to separate an overlapping portion of the original documents. The auto document feeding device reduces a distance between the preceding original document and the following original document passing on the READ document glass to nearly 0 mm.

Abstract: The lengths of an OUT path and an IN path are made longer than the length of a document of a main size in a traveling direction. The document of the main size stands by for conveyance in a direction of a READ document glass in a state where the entire document is contained in the OUT path or the IN path. The entrance speed of the document into the OUT path or the IN path is equal to the read speed of a scanner. The leading edge of a subsequent document is overlapped on the trailing edge of a preceding document, and the document is conveyed to the READ document glass.

Abstract: An auto-document feeder includes: a paper feeding section configured to feed original documents one by one; a first feeding section configured to feed the fed original document through a first feeding path; a second feeding section configured to feed the fed original document through a second feeding path; a third feeding section configured to alternately nip one by one the fed original documents; a determining section configured to determine that the original document is nipped by the third feeding section; and a document diverting and feeding section configured to alternately divert and feed, into the first feeding path and the second feeding path, the fed original documents and, if the preceding original document is present, after the preceding original document is detected by the determining section, feed the following original document into the first or second feeding path into which the preceding original document is not fed.
