Abstract
본 발명은 전화기의 소유자가 기구적인 키록이나 비밀번호를 입력시켜 타인이 전화기를 사용할 수 없도록한 전화기의 록킹 장치에 관한 것으로서, 이러한 본 발명의 목적은 첫번째로 록킹키입력에 따라 스위칭되는 록킹부(9)와, 상기 록킹부(9)로부터 출력된 신호에 의해 다이얼링 신호를 차단시키는 다이얼링 신호 차단부(10)를 구성함으로써 달성되고, 두번째로 스피치부(7)로 부터 출력된 DTMF 신호를 검출하는 DTMF 검출부(13)와, 상기 DTMF 검출부(13)로부터 출력된 데이타와 비밀번호 메모리부(11)에 저장된 비밀번호 데이타를 비교하고 그 결과값으로 장치전체동작을 제어하는 제어부(12)와, 상기 제어부(12)로 부터 출력된 제어신호에 의해 스위칭되어 상기 다이얼링 검출부(4)에서 검출된 다이얼링 신호를 록킹시키는 다이얼링 록킹부(14)를 구성함으로써 달성된다.The present invention relates to a locking device of a telephone in which the owner of the telephone inputs a mechanical key lock or password so that others cannot use the telephone. The object of the present invention is to firstly switch a locking portion 9 according to the locking key input. And a dialing signal blocking unit 10 for blocking a dialing signal by the signal output from the locking unit 9, and a second DTMF detecting a DTMF signal output from the speech unit 7; A control unit 12 for comparing the detection unit 13, the data output from the DTMF detection unit 13 with the password data stored in the password memory unit 11, and controlling the overall operation of the device with the resultant value; and the control unit 12 By configuring the dialing locking unit 14 to be switched by the control signal output from the) to lock the dialing signal detected by the dialing detection unit 4 It is made.
