ABSTRACT:
A film saving apparatus for photographic camera in which a spring loaded stop member projects into the film path when the rear door of the camera is swung open. The stop member is positioned to engage a notched portion of the leader end of a conventional roll of 35 mm film after the tongue portion is received onto the take-up spool. The stop member is retracted when the camera door is closed by virtue of a camming action exerted by the door member on the stop member overcoming the action of the spring. The 35 mm film now passes over the stop member which is retracted out of the film path.
