ABSTRACT:
A film transport mechanism for a camera comprises drive means for advancing a filmstrip beginning with a leading end portion along a defined film path from a film cartridge, and a perforation sensor for detecting a turn-around perforation in a trailing end portion of the filmstrip to initiate return of the filmstrip along the defined film path to the film cartridge. The perforation sensor has a sensing position in the defined film path to be received in the turn-around perforation when the turn-around perforation is advanced to the perforation sensor. A film divertor has a diverting position in the defined film path to direct a forward edge of the leading end portion of the filmstrip over the perforation sensor. A film presence sensor is located to sense the forward edge of the filmstrip after the film divertor directs the forward edge over the perforation sensor, for retracting the film divertor from the defined film path to allow the perforation sensor to be received in the turn-around perforation.
