ABSTRACT:
Automatic photographic developing apparatus in which the photographic material to be developed is placed in a cylindrical drum. The drum is laid on its side on a set of rollers, one of which causes it to rotate. A plurality of containers for various photographic liquids are provided with valve arrangements by which their contents are delivered either in total or in measured increments to the rotating drum. The drum is mounted in a cradle so that it can be tilted to drain liquids from it. Specific details are given of the drum, its driving and cradle tilting components, the liquid dispensing and metering components, and the program control apparatus whereby the photographic materials may be treated with selected solutions in selected orders for predetermined intervals.
