Aperture Card to Card Copier and Reproducer

This machine has a master card feed, a punch card feed and an aperture card developing and processing unit,

The master card feed consists of 80 reproducing brushes and 80 comparing brushes. The 80 reproducing brushes read the information from the card to be reproduced and signal the punch unit to punch, The 80 comparing brushes are for checking the accuracy of this reproduced card, The master card is then fed by an offset pusher to a merge and exposure station located between the master card and punch card feed units. Each master card processed in the master card feed unit contains an image bearing film piece. This is copied onto unexposed film pieces contained in the punch cards.

The punch card feed feeds an unexposed blank aperture card through 80 punches controlled by the master card feed reproducing brushes. The card is then fed to the punch brushes. These are for comparing the information just punched with that of the card in the read unit from which information was read. The punch brushes are also used to signal the punch magnets to operate in a gang punching operation. The punch card is then also fed by an offset pusher to the merge and exposure station. Any number of blank cards are reproduced from one master card depending on the physical limitations of card processing and feeding.

The cards are merged at the exposure station with the master card on top of the punch reproduced card. The image on the master card...
