ABSTRACT:
An apparatus for conveying a photographic film is structured such that, when it is determined that an image frame does not exist, information indicating the image frame does not exist is recorded by a recording head onto a magnetic recording layer which corresponds to an image frame recording area. Accordingly, before the image frame is positioned at the subsequent processes for operation, by reading the information on the magnetic recording layer, it can be detected that the image frame does not exist in an image frame area. Further, it is not necessary to position the image frame area in which the image frame does not exist and only the image frame area in which an image frame exists are positioned for printing.
