Abstract: An installation for processing of photograph envelopes intended to equip a large photography processing laboratory. The installation includes a picking station, a bar code reading station, a thickness detection station, a station for recognition of shapes and characters, a manual input and introduction station, a marking station, and finally a station for feeding a traditional sorting machine.

Abstract: An apparatus for marking the back of a photographic proof with data corresponding to data on the corresponding negatives in a system where the negatives are on a film strip having at each negative an edge notch and the proofs are on a print strip having spaced cutouts comprises a film drive for advancing same from the upstream to the downstream drive roll past a read location. A sensor detects the film-advance speed and generates an output corresponding thereto. A print drive advances this strip past a write location. Another sensor detects the paper-advance speed and generates an output corresponding thereto. A controller is connected to at least one of the drives and to the sensors for synchronizing displacement of the strips past the respective locations such that each proof is at the write location generally when the respective negative is at the read location. Another detector generates an output each time a notch is in a predetermined position at the read location.
