ABSTRACT:
A document microfilming system for information retrieval is provided having photographic apparatus for recording of series of documents on microfilm and identifier indicia printing means for applying an identifying number to the documents or sets of documents. The photographic apparatus comprises means auxiliary to that forming images of the documents on the film strip for forming a designator image on the film strip in adjacent, proximate relationship to images of selected documents. The identifier indicia imprinting means applies an identifying number to each primary document and also applies the same number to all sub-documents associated with that primary document. The control circuit systems include photodetector sensing devices that are designed to detect the presence of identified primary documents for control and operation of the photographic apparatus and identifier imprinting means to cause forming of a designator image on the film strip adjacent the image of a primary document and to increment the numerical printing device to the next sequential number upon detection of the entry of a primary document to the microfilming system apparatus. The primary documents utilized in this system are provided with indicia which differentiates the primary documents from all sub-documents in a set of documents forming a complete supply of information pertaining to a particular subject and facilitates subsequent retrieval of that information through minimizing of the indicators and designator images on the film strips.
