Abstract
An automatic document feeder provided on a copying machine, includes a document feeding unit, a transporting unit for transporting documents to a specified position on a platen and discharging the document therefrom, a pair of pinch rollers for registering the leading edge or trailing edge of the document, and a discharge roller for discharging the documents onto a tray. As the trailing edge of a first document has been registered by the pinch rollers, a second document is fed and the leading edge thereof is registered by the pinch rollers. The document in a pair serially aligned by the pinch rollers, are serially placed at the specified position on the platen. Further, the documents are discharged from the platen with a proper interval so that the leading edge of the second document does not push the trailing edge of the first document.
