Abstract

본 발명은 광다이얼 기능을 구비한 전화기에 있어서 주변의 밝기에 따라 광다이얼의 밝기를 자동으로 조절할 수 있도록 된 광다이얼의 밝기 자동조절 기능을 갖춘 전화기에 관한 것으로, 전화기의 버튼을 밝게 비추는 키발광부를 갖춘 전화기에 관한 것으로, 전화기의 버튼을 밝게 비추는 키발광부를 갖춘 전화기에 있어서, 송화자의 단국장치로 부터 인가되는 링신호를 감지하는 링신호감지부와, 훅크스위치의 온훅 또는 오프훅 상태를 검출하는 훅검출부, 주변의 밝기를 소정 등급으로 나누어 현재의 조도레벨에 따라 해당 등급의 감지신호를 출력하는 조도 감지부, 입력되는 신호를 근거로 다수의 출력단자 중 약정된 하나의 특정단자로만 선택적으로 스위칭제어신호를 출력하는 디코더, 이 디코더로부터 출력되는 스위칭신호에 따라 상기 키발광부의 동작전원 공급을 위한 서로 다른 전류통로를 형성하는 밝기조절부, 및 상기 링신호감지부 또는 훅검출부로부터 소정 검지신호가 인가되게 되면 이를 근거로 상기 디코더측으로 소정 제어신호를 출력함으로써 상기 키발광부로 인가되는 동작전원을 선택적으로 제어하는 제어부를 포함하여 구성된 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a telephone having a function of automatically adjusting the brightness of an optical dial, in which a telephone having an optical dial function can automatically adjust the brightness of the optical dial according to the surrounding brightness. A telephone having a unit, comprising: a telephone having a key light emitting unit for illuminating a button of the telephone, the ring signal detecting unit detecting a ring signal applied from a talker's station device, and an on-hook or off-hook state of a hook switch; Hook detection unit to divide the brightness of the surroundings into a predetermined class and output a sensing signal of the corresponding class according to the current illuminance level, selectively based on the input signal only one specific terminal of a plurality of output terminals A decoder for outputting a switching control signal, the key light emitting unit in accordance with the switching signal output from the decoder Brightness control unit to form a different current path for supplying the operating power, and when a predetermined detection signal is applied from the ring signal detection unit or hook detection unit based on this outputs a predetermined control signal to the key light emitting unit by applying It characterized in that it comprises a control unit for selectively controlling the operating power to be.
