ABSTRACT:
The present invention provides an improved device for transporting photographic negatives mounted on carrying cards to the optical stage of a photographic printer. A storage bin houses a plurality of the carrying cards prior to being transported to the optical stage of the printer. A first vacuum member releasably engages one of the carrying cards and transports that carrying card to a predetermined intermediate location. A second vacuum member operates to transport the carrying card between the intermediate position and the optical stage of the photographic printer. A third vacuum member operates to transport the carrying card from the predetermined intermediate position to a discharge bin. A secondary carrying card transport assembly is adapted to transport at least one carrying card having a secondary photographic negative mounted thereon to the same predetermined location to simultaneously transport multiple negatives to the optical stage of the printer.
