ABSTRACT:
A roll film and a photographic camera cooperate to facilitate automatic attachment of the film to a rotatable film take-up spool. The roll film has a leader portion provided with a novel connecting aperture that includes a flexible tongue element which extends forwardly into the aperture. The camera includes a rotatable film take-up spool which is provided with a capturing member having a head surface, a leading edge surface and a trailing edge surface provided with a recess. The leading edge surface of the film capturing means engages the film aperture upon rotation of the take-up spool and the head surface flexes the tongue element sufficiently to allow the head surface to pass through the plane of the film. Further rotation of the take-up spool allows the tongue element to snap back into the trailing edge recess of the capturing member to secure the film to the take-up spool.
