DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data card having a microfilm and a lens for reading the microfilm.

U.S. Patent Application No. filed February 21, 1979
No. 13158 discloses a wallet-sized data card with a microfilm and a lens for reading the microfilm. This card is
It consists of a laminated paper with an information section containing information that can be read in a normal way by the naked eye. In the actual manufactured embodiment, the paper card has a microfilm aperture formed at one end and a lens aperture formed at the other end.
When performing the laminated packaging of this embodiment, the lenses and microfilm are loaded into appropriate openings of paper cards, and a plurality of paper cards are continuously fed from a continuous laminating packaging machine. In this machine, a continuous strip of laminated packaging material is fed continuously on both sides of a paper card that is preheated and then fed by a machine located at a remote location, thus attaching the lenses and microfilm. Both sides of the paper card containing are laminated. Continuous strips of spaced laminated paper cards are fed from the machine with the laminated wrapping material extending beyond each side of the paper cards. This strip of paper card is fed through a cutter which cuts the outside of each card leaving a strip of laminate wrapping material on all four sides of the paper card. The laminate wrapping material covering both sides of the viewing area of the lens on each card is removed by a cutting head, leaving only a small portion of the laminate material around the outer periphery of each side of the lens to hold the lens in place. .

Although this method produces suitable cards,
There is a drawback that sometimes the preheated laminate strip will sag and grab one of the lenses and twist the card. Furthermore, in the lamination packaging process,
Because the lens is held temporarily in place by the friction of the laminate packaging, the lens can often become displaced from its aperture.

SUMMARY OF THE INVENTION An object of the present invention is to provide a process for producing a data card that has a microfilm and a reading lens and that solves the above problems.

Another object of the invention is to provide a data card in the form of a microfilm and a reading lens, the lens being attached to the card by a novel method and process.
