Claims (1)

[Scope of Claim for Utility Model Registration] In a copying machine equipped with an automatic document feeder that automatically feeds a document to a predetermined position on a contact glass and makes copies, the document is fed by the automatic document feeder. a first detection means for detecting when the original is not fed to the predetermined position; and a first detection means for detecting when the original has not been fed to the predetermined position; and a second detection means for detecting whether or not transfer paper is present at a position in the middle of feeding the transfer paper, and restarting the copy operation. At times, when the second detection means detects that the transfer paper is present at a position in the middle of feeding the transfer paper, the copying operation control means does not feed a new transfer paper. A copying machine with an automatic document feeder, characterized in that the copying machine is configured to restart the copying operation.
