Abstract
A copying machine equipped with an automatic document feeding device has a document stacker on which a plurality of documents can be stacked, a feeding section in which a sheet of document is separated from plural documents stacked on the document stacker and is fed to an image reading section, a conveyance section in which the document fed to the image reading section is conveyed and is stopped at a predetermined image reading position and then the document, after being read, is conveyed, and a sheet-ejecting section which is located at the downstream side in the conveyance direction from the image feeding section and ejects the document fed out of the conveyance section to a delivery tray. A document trailing edge detector is provided on the document stacker, a pass of the trailing edge of the last document on the document stacker is detected, and detection signals therefrom are sent to a main body of the copying machine to control a sheet feeding of the sheet feeding section of the copying machine.
