Abstract

본 발명은 팩시밀리장치에 추가로 외부 전화기를 부착할 경우 이 되부 전화기에 링을 울려주기 위한 팩시밀리용 링 발생 장치에 관한 것으로, 송신측 팩시밀리장치로부터 데이터가 수신되어 입력되는 링 온 신호에 따라 전원을 공급하거나 차단하는 온/오프(ON/OFF) 회로; 상기 온/오르 회로가 온되면 페라이트 코아를 이용한 변압기(L)를 통해 주파수를 발진시키는 자려 발진 회로; 상기 자려 발진 회로에 의해 발생되는 전압을 직류로 정류하는 정류 회로; 소정의 링 신호를 입력받아 추력하는 링 신호 입력회로; 상기 정류 회로의 출력을 출력함과 동시에 상기 정류 회로와 링 신호 출력회로에서 출력되는 상기 정류 회로의 출력에 따라 기본적으로 부착되는 전화기의 링이 울리도록 하는 훅 감지회로를 구비하는 것을 특징으로 하여 팩시밀리장치의 전체 크기를 줄여 소형화를 추구하는 사용자의 욕구를 충족시킬 수 있는 효과가 있다.The present invention relates to a facsimile ring generating device for ringing a ring to a second telephone when an external telephone is additionally attached to the facsimile apparatus. ON / OFF circuit to supply or cut off; A self-oscillating circuit for oscillating a frequency through a transformer (L) using a ferrite core when the on / or circuit is turned on; A rectifier circuit for rectifying the voltage generated by the self-oscillating circuit into direct current; A ring signal input circuit that receives a predetermined ring signal and thrusts it; And a hook sensing circuit for outputting the output of the rectifying circuit and simultaneously ringing a ring of a telephone which is basically attached to the output of the rectifying circuit output from the rectifying circuit and a ring signal output circuit. The overall size of the device is reduced to meet the needs of users seeking miniaturization.
