ABSTRACT:
An apparatus for transporting a film in an APS camera and for magnetically writing data on the film includes a release switch, a single perforation sensing unit, a controller, a film transporting unit, and a data writing unit. After a frame of the film is exposed, the controller starts to write data after a first perforation is sensed and stops the film transport operation after a second perforation is sensed. The controller decreases a pulse period of a transport signal controlling the film transport operation when the second perforation is being sensed, and stops to output the signal after the second perforation has been sensed.
