Abstract

The invention relates to a flat lightproof flexible film cassette for at least two photosensitive strip films suitable for taking several pictures, in which the strip films lie with their longitudinal edges one above the other and are arranged in the film cassette in such a way that after a first film strip has been exposed, the cassette is removed from the camera and, after rotation parallel to one of its axes (L, Q, V) may be re-inserted for exposing the next strip.
