摘要:
A film feeding apparatus which feeds a film wound on a supply reel to a take-up means and rewinds the film on the supply reel, comprising: a driving shaft for removably receiving and holding the supply reel on which the film is wound and for rotating the reel; a driving means for rotating the driving shaft in a normal or reverse direction; a judging means for judging a rewinding direction of the film wound on the reel held by the driving shaft; and a control means for controlling the driving means to change a rotational direction of the driving shaft in response to the rewinding direction judged by the judging means, when the film is rewound.
