PURPOSE:To reduce miscopying and to take a both-surface copy through an easy operation when the both-surface copy of an original is taken by providing a processing circuit which has a calculating means for calculating the maximum number of originals which can be copied and an original sensing-out control means. CONSTITUTION:The processing circuit 40 is provided with the calculating means which calculates the maximum number of originals which can be copied based on a copy quantity inputted from an operation part 41 and the permissible quantity of a storage means and the original sending-out control means. The original sending-out control means of the circuit 40 performs control so that a next original is not sent out to an automatic original feeding device 3 when originals are copied up to the maximum number calculated by the calculating means. Consequently, sheets of copying paper where one-surface sides of originals are copied by the input copy quantity are stacked in the storage means and the next original is not sent out of the means 3 when the copying operation for the maximum number of originals is finished. Therefore, the originals sent out of the means 3 are copied by the input quantity without fail and originals left at the means 3 are easily detected as originals before copying operation, so miscopying is reduced and both-surface copying operation is performed through the easy operation. |
