ABSTRACT:
A single message recording and readout device that employs a rigid elongated stick having at least one flat surface thereon containing a magnetic recording tape for recording and playing back short messages. A guideway for slidably receiving said stick passes through a housing containing a drive unit and appropriate electrical recording and playback circuitry. The drive unit includes a pair of pinch rollers that are mounted within the passage of the guideway for driving the stick along a linear path of travel past a magnetic head. A switch, which is operatively connected to the drive unit, and the recording and playback circuitry is positioned at the entrance to the passage which activates the drive unit as the leading edge of the stick passes through the entrance region and which further deactivates the drive unit when the trailing edge of the stick clears the entrance region. A function switch is further provided for manually selecting a desired mode of operation so that when the stick passes the magnetic head a message is either placed thereon or, alternatively, a message previously recorded is read out.
