An apparatus for transporting film within an APS camera includes a perforation sensor, a controller, a film transporter, and a motor. The controller receives signals from the perforation sensor, and controls the film transport in response to the electric signal. The control unit also controls the film transporter to rewind the film and then wind the film to a predetermined position. During winding the controller counts a time period during which a perforation is not sensed by the perforation sensor, and compares the time period with a predetermined time. The controller then controls the film transporter to wind the film so long as the time period is less than the predetermined time; and stopping winding of the film at a position when a state of a signal from the perforation sensor changes, when the time period exceeds the predetermined time.
