Abstract
In a film reader system in which a film provided with a leader film having a width wider than the width of end flanges of a reel around which the film is wound is wound up around another reel, when a wind-back motor is driven at high speed to wind back around the first mentioned wind-back reel, the leader film is detected by a pair of pinch rollers on the way of the film travelling. Upon the detection, the wind-back motor is electrically braked and the wind-up motor is reversely driven at high speed in the film wind-back direction to release the leader film from the wind-back reel. The wind-back and wind-up motors are then driven in synchronized manner at low speed in the film wind-back direction and the wind-back motor is again driven at high speed upon the detection of the leader film passing the detecting pinch rollers.
