ABSTRACT:
A machine-retrievable card and associated card retrieval apparatus and method therefor is disclosed in which the card is provided with a code-notched sorting edge located between the leading and trailing card edges which has (a) a predetermined configuration of complementary and primary digit code teeth which are retained and removed, respectively, to encode the card with a particular digit, and (b) an acquisition tooth at the leading edge and associated acquisition slot, and (c) a return tooth displaced inwardly of the trailing edge by an associated notch. The card retrieval apparatus includes complementary and primary code blades which selectively engage associated complementary and primary code slots of the card, respectively, as well as an acquisition blade and a return blade which cooperate with the acquisition and return teeth, respectively. The blades engage the card sorting edges and shift in a specified sequence to shift the cards in stages between three principal positions to thereby select a desired card from the deck.
