Abstract

An automatic document feeder for sending a document from a document setting position on a document bearing plate to a document feeding path and returning the document onto the document bearing plate after feeding of the document along the document feeding path. A document mover includes a moving plate for moving the document that has been returned to the document bearing plate to the document setting position. A document presser presses the document that has been moved by the document mover to the document setting position. A controller controls the operation of the document presser and the document mover. The controller operates the moving plate of the document mover to move the document that has been returned to the document bearing plate to the document setting position, then operates the document presser to press the document that has been moved to the document setting position, and causes the moving plate of the document mover to recede, while maintaining the document in a pressed state.
