Abstract

A portable magnetic card reader/recorder is utilized to record tone signals representative of keyed data onto a magnetic card medium for subsequent audio playout. The reader/recorder 11 has a ten-key numerical keyboard 13 for data entry and recessed control buttons 15 for data playback and recording operations. A magnetic card medium 17 is inserted into reader/recorder 11 and scanning lever 19 is moved to a home position thereby winding a spring motor, not shown, which controls motion of a magnetic head escapement mechanism, not shown. Battery power supply 21 provides power to encoding unit 23 responsive to a depressed key of key unit 13 to provide an output frequency signal representative of the depressed keybutton.

Magnetic Card Reader/Recorder

A portable magnetic card reader/recorder is utilized to record tone signals representative of keyed data onto a magnetic card medium for subsequent audio playout. The reader/recorder 11 has a ten-key numerical keyboard 13 for data entry and recessed control buttons 15 for data playback and recording operations. A magnetic card medium 17 is inserted into reader/recorder 11 and scanning lever 19 is moved to a home position thereby winding a spring motor, not shown, which controls motion of a magnetic head escapement mechanism, not shown. Battery power supply 21 provides power to encoding unit 23 responsive to a depressed key of key unit 13 to provide an output frequency signal representative of the depressed keybutton. This signal is applied to magnetic head 25 by magnetic record circuit 27 which also initiates relative motion for a fixed distance between magnetic head 25 and card 17. To listen to or to transmit previously recorded information, scanning lever 19 is set to the desired location and thereafter, play mode control 29 effects relative motion between magnetic head 25 and card 17 causing the previously recorded frequency signal to be applied to amplifier 31 and thence to speaker 33 or communication jack 35. As each character is keyed, a visual representation of the character is displayed on display 28.
