An automatic loader/unloader for a document feeder capable of feeding individual sheets of a document sheet set stack from a supply tray to an exposure station of a reproduction apparatus, and return such sheets to such supply tray, in a circulating manner along a travel path. The automatic loader/unloader comprises a first transport for transporting document sheets seriatim into the travel path, and a second transport for transporting document sheets seriatim from the travel path. A diverter selectively diverts document sheets into, or out of, the travel path. The diverter is controlled to load document sheets sequentially in the supply tray by directing document sheets transported by the first transport to form a document sheet set stack in the supply tray, or to sequentially unload document sheets from the supply tray by directing document sheets from the travel path to the second transport.
