ABSTRACT:
An information storage and retrieval system is provided in which document information, such as images of documents and the like, is recorded on film strip disposed in magazines. Selective monitoring of individual image frames is effected by means of an electro-mechanical system in which selected film strip magazines and an electro-optical scanning device are selectively prepositioned with respect to each other and mechanical coupling is effected between a motor operated drive means and the film strip of the selected magazine, which is thereafter driven past the electro-optical scanning means until the selected image frame of the film strip is aligned with the scanning means. Information contained in the selected frame is then visually monitored and if it is desired to provide a hard copy thereof, a copy producing device is provided to generate a print.
