Abstract
A photographic film carrier is provided for a printer-processor which is switchable in three operation modes, i.e., in a fully automatic mode, an automatic mode, and a manual mode. The photographic film carrier carries a photographic film on which an image frame is consecutively recorded, and positions each image frame at a printing position in order. The photographic film carrier is provided with a control unit to detect an abnormality that the image frame can not be accurately positioned. The control unit determines in response to the cause of the abnormality detected according to a current operation mode of the printer-processor whether or not an abnormality signal should be output. The control unit outputs the abnormality signal when it is determined in response to the detected abnormality that the abnormality signal should be output. Therefore, it is possible to effect an efficient operation according to each operation mode since the abnormality signal can be appropriately output according to each operation mode of the printer-processor.
