PURPOSE:To securely obtain necessary information in a short time without checking a discharged recorded member by comparing image patterns of an original and the recorded member by two sensors which read the image patterns and discharging the recorded member when the patterns conform to each other. CONSTITUTION:When copying operation is started, a sensor 2 provided to an optical system part 3 reads the image pattern of the original. Further, a sensor 11 reads the image pattern of the recorded member. When it is judged that the read patterns are not the same, a changeover flapper 15 operates to guide the recorded member to another tray 14. At the same time, an indication for adding one to the set number of sheets is made. When it is judged twice continuously that the images are not the same, the copying operation is stopped and abnormal occurrence is displayed. |
