ABSTRACT:
A copying machine main body has a document table on which a document is set, a sheet storing means for storing copy sheets, sheet amount detecting means for detecting if an amount of the copy sheets in the document storing means has reached a predetermined value, feeding means for individually feeding the copy sheets from said copy sheet storing means, and image forming means for forming, on the copy sheet supplied by said copy sheet feeding means, and an image of the document set on the document table. The copying machine main body further includes an automatic document feeder. The automatic document feeder has conveying means for conveying the inserted document to the document table, discharging means for discharging the document from the document table after image formation, document feed inhibiting means for inhibiting supply to the document table of a document following the document after image formation and a detector which detects insertion of the document to generate a copying start signal to the copying machine main body. When there is no more copy sheet in the sheet storing means, a detecting signal from the sheet amount detecting means is transmitted to the microprocessor. The microprocessor supplies a driving signal to the discharging means to discharge the document.
