Abstract
A slidable carriage adapted to receive and carry an information bearing credit card along a linear path in traversing registry with respect to an informational read head. A spring and dashpot cooperate with the carriage during movement thereof for limiting the velocity of the carriage to assure proper credit card reading.
Claims5
A manually-operable credit card reader for reading information from an information bearing credit card comprising:
- a base member;
- carriage means adapted to carry an information bearing credit card, and slidably mounted on said base member for manual movement along a linear path;
- an information read head mounted on said base member in alignment with the path of movement of the credit card and operable during said manual movement of said carriage means, for effectuating proper sensing of the information borne by the card;
- and
- restraining means cooperating with said carriage means during said manual movement thereof for limiting the velocity of said carriage means to a prescribed range of velocities as said carriage means is moved past said informational read head, said restraining means comprising:
- a. first means for applying a substantially constant force opposed to the direction of movement of said carriage means;
- and
- b. second means operating in parallel with said first means for applying a force responsive to the magnitude of velocity of said carriage means.
