단축다이알 기능을 갖는 전화기Phone with Speed Dial Function

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 회로도1 is a circuit diagram of the present invention

Claims (1)

전화회로부(1)와 교환국(2)사이에 연결된 스위칭용 MOS전계효과 트랜지스터(3)의 베이스는 입, 출력장치(4)를 통해 메모리(5)와 연결된 중앙처리장치(6)에 연결하되 입, 출력장치(4)의 출력(O1)은 국선 구동기(7)를 통해 교환국(2)에 연결토록하며, 입출력장치(4)의 입력(11)은 전화회로부(1)출력(D1)에 연결되하고, 입력(12)은 모드선택용 스위치(SW)와 트랜지스터(QO)및 저항(RO)으로된 모드 선택신호 발생기(8)에 연결하여 스위치(SW)를 누르지 않거나 3회이상 누르면 전계효과 트랜지스터(3)를 온사켜서 통신의 전화기에서와 같이 동작톡록하고 스위치(SW)를 한번누르면 전계효과 트랜지스터(3)를 오프시키고 전화 회로부(1)로부터 입력되는 단축다이알데이타를 해석하여 메모리(5)내에 기억되어 있는 소정전화번호를 국선구동기(7)를 통해 출력하여, 스위치(SW)를 두번 누르면 전화회로부(1)로부터 입력되는 단축다이알과 전화번호를 메모리(5)에 기억시키도록 하여서된 단축다이알 기능을 갖는 전화기.The base of the switching MOS field effect transistor 3 connected between the telephone circuit unit 1 and the switching center 2 is connected to the central processing unit 6 connected to the memory 5 through an input and an output device 4. The output O 1 of the output device 4 is connected to the switching center 2 through the trunk line driver 7, and the input 1 1 of the input / output device 4 is the telephone circuit unit 1 output D 1. Input (1 2 ) is connected to the mode selection signal generator (8) consisting of a mode selection switch (SW) and a transistor (Q O ) and a resistor (R O ) so that the switch (SW) is not pressed or When pressed three times or more, the field effect transistor 3 is turned on and operated as in a telephone of communication. When the switch SW is pressed once, the field effect transistor 3 is turned off and the short-circuit data input from the telephone circuit section 1 is analyzed. Outputs a predetermined telephone number stored in the memory 5 through the trunk line driver 7 to switch SW. Two press the phone having the speed dial function hayeoseo to remember the speed-dial the telephone number input from the telephone circuit (1) in the memory 5. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
