Abstract: A film cassette is disclosed wherein a film spool is rotatable within the cassette shell, a convoluted film roll whose outermost convolution is a film leader is coiled about the spool, a pair of film constraining flanges are coaxially arranged on the spool to radially confine the film leader to prevent the leader from substantially contacting an interior wall of the cassette shell, and a film stripper-guide is received between a leading end of the film leader and the next-inward convolution of the film roll succeeding the leader to remove the leader from the flanges and guide it through a film passageway to the exterior of the cassette shell responsive to rotation of the spool in a film unwinding direction.
