PROBLEM TO BE SOLVED: To prevent an error and a skip in copying an original by reading an invalid original image again and controlling the driving of a pair of resist rollers, so as to time with the obtained visual image on a photoreceptor. SOLUTION: A delay detecting part 4 detecting the delay of a transferred material is installed in front of a pair of the resist rollers 3, in the carrying direction and the output of the delay detecting part 4 is connected to a control printed board 7. Further, a drive control part 5 is provided between the control printed board 7 and a pair of the resist rollers 3. In this device, when the delay of the transferred material reaching a pair of the resist rollers 3 from a paper feeding part is detected within a previously set range, the visual image obtained by a reading means 1 is invalid, the invalid original image is read again and a pair of the resist rollers 3 are controlled to time with the obtained visual image on the photoreceptor 2. Therefore, a transfer is accurately performed to the delayed transferred material, when reading is performed at the second time. |
