PURPOSE:To make the total number of times of circulations smaller than that of a conventional device, to decrease the breakage of an original and to shorten total copying time by copying the even-numbered pages of the original in a first original circulation, copying both faces in subsequent circulations and copying its odd-numbered pages in the last circulation. CONSTITUTION:The title device is provided with an intermediate storage means 24c to once store a copying paper on whose one face an original picture is copied, a carrying means 24d to carry the copying paper stored in the intermediate storage means 24c to a picture forming position. The title device is also provided with a copy control means 4 to copy the even-numbered pages of the one-face original in the first circulation of original feeding, copy the odd- numbered pages of the one-face original onto the copying paper once stored in the intermediate storage means 24c in and after a second circulation, carry the copying paper on which the even-numbered pages are copied to the intermediate storage means 24c and copy the odd-numbered pages in the last original circulation. Thus, the total copying time is shortened and the breakage of the original is prevented. |
