Abstract An automatic duplex copying machine with a circulating document handler is characterized in that a plurality of single-sided-image bearing documents are piled on the circulating handler and a document page having been copied on a front side on a copy paper is sheltered in a copier-paper discharge path of the circulating document handler. Upon the occurrence of a paper jamming during copying another document page to be copied on the rear side of the copy paper, another document is sheltered into a document reverse tray of the circulating handler. The document with the front side page sheltered in the paper discharge path is forwarded into a document table, again, to conduct a supplemental copy. After that, the document with the front side page is sheltered in the document discharge path and the document with the rear side page is forwarded into the document table, again.
An electrophotographic copying machine of the type in which at least two single-sided image bearing documents to be copied are circulated to rest on a document table for scanning, to make a double-sided copied paper bearing first and second images, comprising: document circulating means for carrying the single-sided image bearing documents thereon and circulating the documents prior to arrival at the document table; first shelter means for sheltering a first page document of the documents; and second shelter means for sheltering a second page document of the documents upon the occurrence of a paper jam in copying the second page document; said first shelter means dispatching the first page document to the document table for supplemental copying; said first shelter means further sheltering the first page document after the supplemental copying thereof; said second shelter means dispatching the second page document to the document table to thereby carry out copying thereof.
