Magnetic or Optical Record in Slot Scanner

This scanner is designed for use with card records having data recorded in RPM and F2F and like coding, readable at varying speeds with varying velocity demodulating logical circuitry.

The basic components comprise a body member 10 having an elongated slot 12 running therethrough, a transducer 14. (such as an electro-magnetic or an optical transducer) arranged centrally of the body member 10, and a pressure exerting pad 16 (or a similar arrangement for spacing the card 20 from the transducer 14) arranged opposite the transducer 14.

To read a card 20, the holder slips it into the slot 12 at one end of the body member 10 with the magnetic (or optical) record adjacent the transducer, and manually draws the card 20 past the transducer 14 at a speed which may vary in the range of 2 to 50 inches Per second.

The width of the slot 12 is a little over maximum card thickness. The bottom and one side of the slot register the card with respect to the transducer 14, which preferably is adjustable with respect to the one side wall. The pressure pad 16 is located in the other side wall of the slot 12 opposite the transducer 14. The pad exerts normal contact pressure of the card 20 against the transducer 14 (or against stops spacing the card away from the transducer) and accommodates a wide range of card thickness (for example, 30 mil. plastic to 7 mil. paper cards).
