ABSTRACT:
A photographic film cassette has a core on which a photographic filmstrip is wound, a cassette shell rotatably houses the core. A pair of disks are loosly fitted to the core, and the disks are engaged with the cassette so as to prevent rotation of the disks with the core. Each disk is formed with a circumferential lip for engagement with two opposite sides of the outermost convolution of a film roll wound on the core. A notch is formed in each circumferential lip. As the film roll rotates with the core, the film leader separated form the film roll passes through the notches. The film leader passed through the notches is then advanced out of the cassette via a film passage slit.
