Abstract

An automatic document feeding device is capable of one-side process and double-side process, and includes a paper supply stacker, a paper supply path for transferring a document fed from the paper supply stacker to a sheet processing section, a switchback path for switching back the document processed at the sheet processing section, a paper ejection path for ejecting the document switched back in the switchback path in a reversed condition, and a paper ejection stacker for receiving the document ejected from the paper ejection path. In the double-side process, in accordance with a sheet size of the document to be processed, the device is controlled to switch between a mode wherein only one document is transferred in and ejected from the switchback path and another mode wherein a second document is transferred into the switchback path in the condition that a first document is still in the switchback path.
