Abstract
Abstract An automatic telephone answering and recording system having a passive circuit for detecting the ringing of a telephone annunciator bell. The signal generated in the circuit is of a sufficient level to cause a passive electronic switching element to become conductive which in turn permits energization of the system. Moreover, the system outgoing message tape is used to actuate a tape rewind mechanism, as well as to control the timing sequence for recording the message on the incoming message tape. The system does not use solonoids, electromechanical relays, alternating current motors or capstan drives and uses a minimum of precision mechanical parts to achieve a low system cost.
