ABSTRACT:
In this telephone answering device, each of the mechanical control arms is pivotally mounted in simplified fashion to a molded plastic chassis. Overcenter springs provide bistable mechanical positioning of each control arm. The answer-playback control arm functions to position an erase head against the incoming message recording tape, to engage or disengage the outgoing announcement tape loop drive, and to actuate a switch that connects power to the device during rewind and playback operations. A forward-rewind control arm shifts the magnetic tape drive motor to the forward or rewind position, and is linked to the answer-playback control arm by a lost motion linkage so as to ensure the correct relative settings of the two control arms.
