Abstract: An automatic document feeder is combined with an optical machine module, and feeds a document to be scanned into the scanning area so that the optical machine module can capture the image on the document. The automatic document feeder according to the invention is designed so that single-sided and double-sided scanning of a manuscript can be attained. It mainly comprises a delivery route that can feed a manuscript through the scanning area, a return route and guiding-out route respectively connected with the delivery route. The manuscript can come out of the exit to complete single-sided scanning after passing through the scanning area. Or, the manuscript can be turned over to its other side and guided back to the delivery route to pass through the scanning area again to process the second scanning. Finally, the manuscript is guided out of the exit and the double-sided image capture is completed.
