ABSTRACT:
In this telephone answering device utilizing microcassettes, a single head carriage carries the pinch rollers and heads for both the outgoing announcement and incoming message tape cassettes. The carriage is linearly movable between an engaged position and one or more retracted positions by a cam assembly utilizing a cam with missing teeth in two or more areas. The cam is driven between orientations established by the toothless areas, and is held in these areas by a selectively engaged pawl. A lever driven by the cam moves the unitary head carriage between engaged and retracted positions. A set of idler wheel slider assemblies is provided for selective driving of the source and takeup spindles of the two cassettes. These assemblies are selectively engaged in response to the position of the single head carriage and the direction of drive of the cassettes.
