ABSTRACT:
An automatic document feeder for use with an electrophotographic copier, digital copier or similar image recorder capable of transporting ordinary documents in the form of separate sheets and a continuous document in the form of computer form (CF) paper which is formed with equally spaced sprocket holes, as desired. A sprocket hole sensor is disposed on an imaginary line along which the sprocket holes of the CF paper are moved. A control device reversibly controls the transport of the CF paper to a predetermined reference position on a glass platen in association with the number of sprocket holes being counted. The document feeder is capable of not only copying a desired page of the CF paper but also implementing jam recovery in the event when a paper sheet jams the image recorder.
