Abstract
Apparatus for automatically feeding a film to the outside of the reel on which the film has been rolled around. The film has a leader part affixed to the forward end of the film. The width of the leader part is larger than the width of the image recording part of the film. The reel has a pair of flanges disposed spaced from each other by a distance smaller than the width of the leader part. The leader part is rolled around the outer circumference of said paired flanges. A feed roller is provided to feed out the leader part to the outside of the reel. The feed roller has a width smaller than the space between the paired flanges and is movable between a position outside of the paired flanges and a position inside of the flanges. The position of the feed roller is detected by a detector which detects that the whole leader part has been fed out from the reel.
