ABSTRACT:
Apparatus for developing photographic film includes a substantially cylindrical, open sided carrier which retains spaced-apart parallel sheets of photographic film within the cylinder. A plurality of horizontal open-topped chemical troughs are disposed side-by-side with a second lip of each trough in the series being disposed adjacent a first lip of the succeeding trough in the series. The film carrier is deposited adjacent the first lip of the first trough. A transport mechanism in each trough rolls the carrier along the inner surface of the trough so that it is ejected over the second lip and drops into the next succeeding trough in the series. The carrier is finally ejected over the second lip of the last trough into a drying chamber where it is subjected to a flow of heated air. The processor is particularly suitable for processing sheets of intraoral dental film.
