PROBLEM TO BE SOLVED: To provide a copying device with an inexpensive and compact recirculating type both-side copying function and enabling continuous both-side copying of the number of sheets equal to or exceeding that of recording papers stored by a circulation paper passing path without a memory function. SOLUTION: The device is constituted of an automatic document feeder 80 equipped with a document reversing roller 91, a copying machine body 10, and a duplex sorter 100 equipped with a circulating carrying part 150 for reversing the recording paper ejected from a pair of ejecting rollers 73 of the copying machine body 10 and carrying the paper to a pair of timing rollers 65. In this case, at copying the number of sheets exceeding the number of recording papers stored by the circulating carrying part 150 at both-side document/both-side copying, the document is turned upside down by the automatic document feeder 80 whenever the number of continuously copied sheets reaches the number of the stored sheets. |
