Abstract
Document feeding apparatus for feeding original documents of varying length to the copying station of a copier machine. If the document is less than or equal to a predetermined length, the document is moved to the copying station, a corresponding copy is made, and the original document is then transported to an exit stacker. If the original document exceeds the predetermined length, which length is slightly less than the length of a copy document, then the feed moves the original document to and through the copy station in increments slightly shorter than the length of the copy document, until the entire length of the original document has been copied. A particular use of the invention is in connection with the copying of adding machine tapes.
