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locking members are operative to preclude the drawing out of the other cards and the plurality of the selector bars are withdrawn over the retrieved card transportation course.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.
