<p>A multi-purpose film handling cassette adapted for use with a motion picture camera and projector of the type including a film transport mechanism for progressively transporting an incremental section of a film strip, stored on a supply reel within the cassette, past a cassette exposure and projection station. The cassette is provided with a film tension regulator for establishing a feed loop of film strip between the supply reel and the exposure and projection station to isolate that portion of the film strip near the exposure and projection station from the inertial drag of the supply reel thereby preventing the film transport mechanism from applying excessive pressure to the film strip. The tension regulator is also configured to guide the film strip onto the supply reel in a manner which precludes disturbing a coating of liquid processing composition applied to the film strip during a processing mode of operation.</p> |
