Abstract: A microfilm aperture and handling machine has punched card reading and punching means, single means capable of both scanning and plotting microfilm images, a photographic developer station for developing plotted images, and control means enabling selective operation to read existing data carried by a card or to create data on a previously blank card. The machine integrates functions normally found only in separate machines. The single scanner/plotter means scans a microfilm image from the central axis of a cylindrical platen. The developer station injects chemicals into a chamber of which the microfilm emulsion area forms one wall by peripheral clamping.

Abstract: A data storage card has an aperture for receiving a photographic image. The aperture has an adhesive border which is protected by a disposable sheet having release characteristics. One edge of the sheet extends outwardly to form a flap overlying the card. By bending the card, for example, the flap can easily be separated from the card and a knife edge inserted to strip the sheet from the card.

Abstract: A microfilm card duplicating machine is arranged to feed master cards sequentially to a copying station. The master cards have images thereon for duplication by the machine. Copy cards are fed by the machine one by one to the copying station for producing a required number of copies. The copy cards and master cards are routed to a receiving station after copying while the master card is delayed such that it arrives at the receiving station only when its duplicate copy card(s) have been delivered thereto. The sequential delivery enables the formation of an interleaved stack of master and copy cards arranged with the copy card(s) being preceded in each case by the associated master card.
