Abstract
A film transporting device for use in a camera disclosed is so designed as to rewind the film such that no film portion is engaged in film take-up sprocket, resulting in an easy take out of the use film. The device in one form includes a counter that counts up the number of frames during a wind-up operation is carried out after the positioning of a film leader in contact with the take-up sprocket, and during a rewind operation, the counter counts down the same number of frames, or more, to locate the film leader in a disengaged position from the sprocket. The device in another form includes a film perforation detector. In this form, the film rewind operation is carried out until the perforation detector stops detecting the perforation. In a further form, the device includes a mechanical counter which counts up the frames used during wind-up operation, and during rewind operation counts down more than the number counted up to ensure that the film leader portion is withdrawn from the take-up sprocket.
