Abstract

A card retrieval system in which each card is provided at its one peripheral edge with a magnetic strip which includes a unique notch structure for the purpose of retrieving individual cards. A plurality of selector bars are positioned in a manner to meet at right angles to a stack of the cards, while a magnet is positioned against the magnetic strips of the stacked cards. By the attracting force of the magnet, a specific card is slightly drawn out from the card stack in cooperation with the selector bars and the notch structure. Subsequent to this, locking members are operative to preclude the drawing out of the other cards and the plurality of the selector bars are withdrawn over the retrieved card transportation course. In this manner, the retrieval of a specific card is accomplished by the magnet.

Dependent claims

A card retrieval system comprising:

a multiplicity of cards stored in a stationary stack structure, each of said cards being provided with a face which includes a magnetic strip and a notch structure formed in the magnetic strip;
means for receiving input information for the purpose of selecting a specific card;
magnet means for magnetically attracting the cards;
a predetermined number of selector bars adapted to engage with the notch structures of the cards;
said selector bars being mounted to be rotatable from an inoperative to an operative position and to be laterally displaceable relative to the stationary stack structure;
said selector bars being mounted to be movable along the face of the cards in response to input information;
and
said selector bars when in the operative position block the attraction between the magnet means and the non-selected cards to thereby select the selected one of the cards in response to the positioning of the selector bars which is determined by the input information and the attraction of the magnet means.
