ABSTRACT:
A copying apparatus provided with an automatic document feeder capable of operating in a first mode, where one document is placed onto a platen, and in a second mode, where a pair of documents are serially placed onto the platen in the document feeding direction. Sheets in the sheet feeder with longer sides parallel to the sheet transport direction are selected in response to the selection of the second mode. The selection of the second mode is inhibited when the longer sides of copy sheets stored in a sheet feeder are perpendicular to the sheet transport direction. Copying and document feeding in the second mode are inhibited when the sheet feeders do not contain sheets of with longer sides parallel to the sheet transport direction. Further, when only one document is fed and placed onto the platen, the image forming operation to a non-document area is inhibited.
