ABSTRACT:
An automatic document feeder (ADF) used with an image forming apparatus automatically and sequentially feeds a plurality of documents having images thereon from a paper cassette to an illumination position of the image forming apparatus with the topmost document of the plurality of documents fed first. The plurality of documents are placed and stacked in the paper cassette selectively in a sequential page order and a reversed page order. The ADF comprises a first document path, a second document path and a path selector. The first document path directs the documents to the illumination position and discharges the plurality of document after being illuminated to a first document outlet of ADF such that the discharged documents are stacked in the reversed page order when the plurality of documents are stacked in the sequential page order in the paper cassette. The second document path directs the documents to the illumination position and discharges the plurality of documents after being illuminated to a second document outlet of ADF such that the discharged documents are stacked in the sequential page order when the plurality of documents are stacked in the sequential page order in the paper cassette. The path selector selects between the first and second document paths.
