Abstract
본 발명은 전화기의 송수화기가 수납부에 제대로 놓여 있지 않아 기계식 후크 스위치가 온되지 않을 경우 이를 검출하여 기계식 후크 스위치와 병렬접속된 전자식 후크 스위치를 온 상태로 유지시킴으로써 통화대기 상태가 가능하도록 한 전화기에 관한 것으로, 금속 근접체(1)가 장착된 송수화기(2)와; 상기 송수화기(2)가 잘못놓인 경우 이를 인식하여 소정신호를 출력시키는 마이컴(3), 상기 마이컴의 신호를 입력받아 발진을 수행하는 고주파발진회로(4), 상기 고주파 발진회로(4)가 발진을 중지할 때 소정신호를 출력시키는 신호처리 및 출력회로(5), 상기 신호처리 및 출력회로(5)로부터 소정신호가 출력될 때 스위칭 온되는 트랜지스터(Q1), 상기 트랜지스터(Q1)의 콜렉터에 접속된 기계식 후크 스위치(S1)와 병렬접속되어 상기 마이컴(3)의 제어에 따라 스위칭되는 전자식 후크스위치(S2)를 포함하는 본체(6)를 구비하여 이루어진다.The present invention detects when the handset of the telephone is not properly placed in the receiving unit and the mechanical hook switch is not detected on the phone by holding the electronic hook switch connected in parallel with the mechanical hook switch in the ON state to enable the call waiting state It relates to a handset (2) equipped with a metal proximity (1); The microcomputer 3 which recognizes that the handset 2 is misplaced and outputs a predetermined signal, the high frequency oscillation circuit 4 which receives the signal of the microcomputer and performs oscillation, and the high frequency oscillation circuit 4 oscillates. A signal processing and output circuit 5 for outputting a predetermined signal when stopping, a transistor Q1 switched on when a predetermined signal is output from the signal processing and output circuit 5, and connected to a collector of the transistor Q1. And a main body 6 including an electronic hook switch S2 connected in parallel with the mechanical hook switch S1 and switched under the control of the microcomputer 3.
