ABSTRACT:
An aperture card which carries image information in a microfilm mounted on a rectangular paper sheet is widely used as it can conveniently record and control a large volume of image information separately. The aperture card carries a microfilm which records retrieval information corresponding to images of the microfilm at a position peripheral to the images. As such structure of this invention aperture card permits automatic recording of the retrieval information concurrently with the preparation and duplication of the cards, this invention can realize the preparation/duplication system for the aperture cards at a lower cost than before. As the printer suitable for the aperture card can read the retireval information recorded on the microfilm and record them in characters or punches, it can reduce the cost of the system due to the abbreviation of the manufacturing processes and increase the memorandum capacity on paper. The printer may be applicable to automatic punch systems.
