ABSTRACT:
In a film cassette capable of propelling a non-protruding film leader to the exterior of the cassette shell, a camming flange is rotated coaxially with respect to a film spool in a film unwinding direction to deflect one of the flanges of the spool firmly against the outermost convolution of the film roll wound on the spool. This enables rotation of the spool in the same direction to propel the film leader out of the cassette shell.
