ABSTRACT:
A film unit ejection and processing system for instant cameras having a spread roller pressure nip through which an exposed film unit is passed from the camera interior for processing and discharge to the camera exterior. The system includes an opaque feed web to frictionally engage each film unit and having a flight portion extending through the pressure nip to an end secured to a tray supported for reciprocation on the camera exterior. The tray carries guide rollers to support the feed web in a loop configuration so that the end of the web opposite from the tray connected end may be secured to the camera body without interference with film unit feeding by frictional engagement with the web flight portion extending from the pressure nip. The tray further operates a spring biased pick arrangement by which each film unit is advanced to present its leading edge at the pressure nip. Also, the web may be provided with frictional engagement augmenting means such as a roughened traction surface, a spread roller separating formation positioned to immediately precede the leading edge of a film unit into the pressure nip or traction nubs located to push the rear edge of the film unit through the pressure nip.
