ABSTRACT:
A photographic printer or developing machine has a station for processing photographic material. A station for accommodating a mobile, carriage-like cassette in an operative position is disposed adjacent to the processing station on either side thereof. One of the operative stations receives a take-off cassette carrying a reel of photographic material to be processed while the other operative station receives a take-up cassette. An additional station for holding a replacement cassette in a ready position is located next to each of the operative stations. A propelling mechansm for pushing a cassette out of its operative position is provided at each operative station as is a drawing mechanism for pulling a replacement cassette from the ready position to the operative position. In operation, photographic material from a full take-off cassette in one of the operative stations is automatically paid out of the cassette, conveyed through the processing station and coiled into an empty take-up cassette in the other operative station.
