Abstract
Abstract Photographic printer apparatus is a building block arrangement of printer components. An exposure determining device, which produces printer control signals derived from photographic negatives, applies such signals to a computer; and a photographic printer draws such printer control signals from the computer independently of the operation of the exposure determining device. Such an arrangement permits a plurality of printers to cooperate with a common exposure determining device; and further permits photofinishers to avoid equipment redundancies.

Claim 1
Independent Claim
326 words
Photographic printing apparatus comprising: a. first means adapted to sense the optical characteristics of photographic transparencies and the like for producing signals respectively dependent on the said optical characteristics of said transparencies and the like, b. a plurality of photographic printing means for making photographic prints from photographic transparencies and the like, each of said photographic printing means having an exposure gate, c. computer means selectively connectable to said first means, and selectively connectable to each of said photographic printing means, said computer means including means for receiving and storing signals from said first means, and each of said photographic printing means including: 1. means for receiving signals stored by said computer, and 2. means responsive to said stored signals for making print exposures in accordance therewith, d. means, forming part of said first means, for indexing said photographic transparencies and the like through said first means, e. means, embodied in each of said photographic printing means, for indexing photographic transparencies and the like and exposure material past their respective exposure gates, the aforesaid rates of indexing being all substantially independent of each other, f. means forming part of said computer for actuating said indexing means of said first means after the characteristic signals of each transparency and the like have been produced, and g. means embodied in each of said photographic printing means for actuating its respective indexing means after each print exposure thereof has been made, h. means forming part of said first means for producing signals for identifying transparencies and the like and correlating such identifications with respective characteristic signals, i. means forming part of said computer means for storing said identifying signals in relation to respective characteristic signals, and j. means embodied in each of said photographic printing means for use in detecting identifying signals and in response thereto for withdrawing from said computer storing means characteristic signals which correspond with transparencies and the like which are indexed into respective exposure gates.
