ABSTRACT:
An apparatus comprises a feeder for feeding the film, a detector for detecting perforations formed on the edge of the film, a controller for controlling the feeder based on the output from the detector. In the apparatus, the operation of the detector is inhibited after the beginning of film feeding until the tip of the film has passed in front of the detector to prevent the erroneous detection of the perforations.
