Abstract

본 발명은 후크 오프 상태에서도 상대방이 전화할 경우 전화벨이 울릴 수 있도록 하기에 적합한 전화기의 후크 기능 잠금 장치에 관한 것으로, 종래의 기술에 있어서는 사용자 등의 실수로 전화기의 송수화기를 잘못 놓아 후크 오프로 될 경우에 상대방이 전화하면 통화중으로 처리되어 통화할 수 없었으나, 본 발명에서는 사용자에 의해 후크 스위치(SW2)와 정전압 발생부(14) 사이의 접속을 단속하는 스위칭부(22)를 기존의 전화기에 추가로 설치함으로써 송수화기(20)가 잘못 놓여진 경우라도 항상 후크 온 기능을 유지할 수 있으므로 상기 결점을 개선시길 수 있는 것이다.The present invention relates to a hook function locking device of a telephone that is suitable for allowing a telephone to ring when the other party calls even in a hook-off state. In this case, when the other party calls, the call is handled as a call, but in the present invention, the switching unit 22 which controls the connection between the hook switch SW2 and the constant voltage generator 14 by the user is connected to the existing telephone. By additionally installing the hook 20, the hook-on function can always be maintained even when the telephone is placed incorrectly, thereby improving the above-mentioned shortcomings.
