Abstract
A simple mechanism is provided for winding film in a film cassette in which a pawl engages a perforation in each film frame to actuate a film stop device which, in turn, disengages the pawl from the perforation to remove any force from the film during picture taking. Winding force is transmitted from a unidirectionally rotating film feed disc to a reciprocating link and then to a undirectionally rotating spool gear which drives the film spool.
