An automatic film feeder having an arrangement with which films can be reversed manually to re-position the frames of each film. A film magazine is mounted outside of an outer case of the printing machine. Films fed from the film magazine are guided into a film feed passage provided inside the outer case by means of a film guide. The film guide has a loop guide which is openably mounted. When a film is fed backward, it slackens and opens the loop guide forcibly.

Un chargeur est monté à l'extérieur d'une boîte externe de la machine à imprimer. Les films entraînés par le chargeur sont dirigés par un guidage vers un passage d'entraînement du film qui se trouve dans la boîte externe. Ce guidage du film comporte un guidage en boucle monté à découvert. Lorsqu'on entraîne un film en marche arrière, ce guidage se relâche et ouvre de force le guidage en boucle.
