Automatic document transportation device

摘要

An automatic document transportation device has a rotatably supported guide piece at the junction between a document feeding route through which an incoming document sheet to be processed is passed to a scanning position and a discharge route through which the processed document sheet, moving backwards from the scanning position, travels to be discharged. The guide piece normally assumes a downward position by its own weight, thereby blocking the feeding route in such a way that the incoming document sheet can cause it to rotate and travel past it but the outgoing sheet, moving in the opposite direction, is deflected by it into the discharge route.
