Abstract
An automatic document feeder (ADF) for use with an image forming apparatus and freeing the operator from extra work associated with documents discharged after illumination. When the operator intentionally stacks the first page to the last page of documents in this order and sets them on an ADF table face down due to a copy discharge mode which requires the ADF to discharge the last page to the first page in this order face up, the ADF reverses the documents before discharging them. Hence, despite that the ADF discharges the documents from the last page to the first page, it successfully stacks the documents in order of page by turning them over.
