Abstract

전원의 인가유무에 따라 선별적인 통화가능을 수행하는 자동응답전화기에 있어서, 하나의 스피커와, 상기 전원이 인가되지 않은 경우에는 링신호를 변압시켜 상기 스피커로 전송하는 제1수단과, 상기 전원이 인가된 경우에는 링신호 착신을 감지하여 중앙처리장치나 이에 상응하는 소자로 링음을 발생시켜 증폭하여 상기 스피커로 전송하는 제2수단을 구비함을 특징으로 하는 자동응답전화기의 선별통화회로.An answering machine for selectively making a call according to whether power is applied or not, comprising: one speaker, first means for transforming a ring signal and transmitting the ring signal to the speaker when the power is not applied; And a second means for detecting an incoming ring signal, generating a ring tone to a central processing unit or a corresponding element, and amplifying the ring signal to the speaker.
