ABSTRACT:
An apparatus is provided in which a card, such as a credit card, carrying a magnetic strip of one or more tracks of coded data is inserted. Manual operation of an external crank or lever causes the card to be drawn into the apparatus. At the end of the stroke, the carrier in which the card rides is freed from the crank and returns at a constant, spring-driven speed, past a magnetic readout head, the output of which is connected to any suitable decoding circuit. The readout head is gimbaled so that it can ride with constant pressure against the magnetic strip on the card while at the same time adjusting itself to undulations or other slight deformations in the card. There is no significant amount of magnetic material within magnetic range of the readout head, so that danger of spurious signals being injected into the decoding circuit is minimized.
