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 removed and retained, 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 at the trailing edge and 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 a pair of acquisition blades and a pair of return blades 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 home, intermediate and advanced positions to thereby select a desired card from the deck.
