ABSTRACT:
A film disc developing machine, for developing plastic film discs coated on one side with a photographic emulsion enclosed in a housing and having a hub portion with a central hole, in which a film disc to be processed is held in a substantially horizontal position in a light type casing the machine, from which it is picked up on the end of one of a number of downwardly projecting spindles movable around a closed path. The spindles are moved intermittently around this path by mechanisms which raise and lower the spindles intermittently, indexing the whole assembly through a predetermined angle in the raised position; each time the spindles are lowered the lower end of the spindle passes through the hole in the hub of a film disc to engage it frictionally. Beneath the path of the spindles a plurality of processing solution containers are arranged including at least one container for drying. A film disc picked up on the end of a spindle is thus introduced into each processing solution in turn and retained in it for a predetermined period so that on completion of its travel around the path the film disc is fully processed and dried. The spindles are rotated about their axes by a common drive to enhance contact between the emulsion and the processing solutions and preferably a film disc in the drying container is rotated at a higher speed to throw off surplus solution.
