Abstract

PURPOSE:To omit the double-channel structure for the message tape as well as the mark signals for the automatic answering telephone set which reproduces and hears the business message, by producing the pulses in synchronization with rotations of the reel axle. CONSTITUTION:The following component units are provide: the circuit to detect the incoming signals from the circuit and then transmit the answer message; the circut to receive and record the business message; contact SW of the switch synchronized with rotations of axle of message tape 8; forward and rewinding counters CT2 and CT1 to count the switching frequency of SW; and collation circuit 16 which delivers the output when a coincidence is obtained between the count number and counters CT1 and CT2 and then stops the action of tape 8 via relay C.
