A document-ejecting/feeding mechanism is assembled inside an automatic document feeder, includes a driving device, gears, one-way clutches and rollers. After feeding action is canceled, the driving device is reversed and cooperates with the action of gears and one-way clutches, and at least one of rollers that near the paper-ejecting position is still rolled to the paper ejecting direction. Therefore, after the feeding action is canceled, the document will be still moved out from the feeder automatically and not tore.
