Abstract
The mechanism extracts a particular card or cards from a block or library of edge-notch coded cards, in which a card is extracted in response to the appropriate code being keyed in. The mechanism requires only a small movement of the cards (1) themselves, which are normally of thin material such as PVC and each is coded with a number of notches along one edge. The entire stack is held in a rack (4) and may be moved forward by a small ram (10). Beneath the cards are coding bars (8, 9) which fit into the slots. The exact position of these are determined by the input from an alphanumeric keyboard (21, 22, 23) via a series of levers (24, 25). Basically, the selection rods are first positioned by these levers, and the entire pack is then moved forwards to a fixed position. The card or cards corresponding to the code called up fall slightly when the notches fit over the code bars and the remainder of the pack is then moved back to its original position leaving the selected card protruding.
