Abstract

PURPOSE:To improve the operability relating to an incoming call of a specific person by devising the telephone set such that the automatic answering standby state is caused by setting a sound volume changeover switch to the turn-off state. CONSTITUTION:A tone ringer circuit 4 receiving a call signal outputs a ringer tone signal to generate a ringer tone. The ringer tone signal is given to a speaker 10 via a sound volume changeover switch 9. The sound volume changeover switch 9 sets the ringer tone into the so-called bell interruption state where the ringer tone is switched into large/small two-stage and not produced. With the sound volume changeover switch 9 thrown to the turn-off position, an interlocking switch circuit 26 is operated in interlocking therewith and the automatic answering standby state is set. Thus, the specific incoming state is set only by the operation of the sound volume changeover switch 9.

Button signal (hereinafter referred to as PB double signal)
This is about an answering machine that makes a ringtone when you receive a call.

(Prior Art) Conventionally, a changeover switch is provided for switching between an on state in which a ringing sound is generated and an off state in which the ringing sound is not generated, and when this switching switch is set to the on state. a switching circuit that outputs a first generator drive signal for generating the ringing sound when receiving a ringing signal; and a switching circuit that detects a code represented by a push button signal from a calling side telephone and outputs a code detection signal thereof. When a push-button signal detection circuit and an automatic response switch for setting an answering standby state that automatically responds to the calling signal are set to the on state, an operation of generating an automatic response command signal in response to the automatic response ON signal. When the circuit receives this automatic answering command signal, it enters the answering standby state, and when it receives the call signal during this answering standby state and the code represented by the code detection signal is a specific code, it enters the second answering standby state. a specific incoming call control unit that outputs a generator drive signal; and a tone ringer sound generator that receives the first or second generator drive signal and generates the tone ringer sound; There is an answering machine that, by setting a response switch in the on state, makes a tone ringer sound or automatically answers only when a PB double signal representing the above-mentioned specific code is received.
