종래의 키폰 전화기는 부제중 수신거부상태에서 수신거부 톤신호만 상대방에게 알려주면, 부재중 다른사람이 수신하여 메세지를 전해주어야 하는 불편함이 있다.In the conventional key-phone telephone, when only the reception tone signal is notified to the other party in the reception rejection state of the subtitle, it is inconvenient to receive the message received by the other person in the absence.

또한 부재중 일정시간동안 전화를 받지 않으면 상대방이 그냥 포기함으로써 긴급발생한 비상시 상대방은 전화통화를 못하여 재통화에 어려움이 따르는 심각한 문제등이 있다.In addition, if you do not answer the phone for a certain period of time, the other party to give up just in case of emergency emergencies, there is a serious problem that is difficult to re-call by the other party.

따라서 본 발명은 상기한 종래의 불편함을 해소하고, 종래의 문제점을 해결하기 위하여 창안한 것으로, 본 발명의 목적은 부재중이거나 수신거부 상태에서 착신된 상대방의 전화번호를 입력하고 기억시켜 재통화가 가능토록 한 키폰 전화기를 제공함에 있다.Therefore, the present invention is to solve the above-mentioned conventional inconvenience and to solve the conventional problems, the object of the present invention is to enter and store the phone number of the called party in the absence or rejection state and re-call It is to provide a key-phone phone that is possible.

이하 첨부된 도면에 의하여 본 발명의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면은 본 발명의 키폰 전화기 기능별 블럭 구성도이다.The accompanying drawings are block diagrams of functions of a key phone according to the present invention.

상기 도면에서 송수신되는 음성신호(1)를 분리하는 하이브리드 트랜스(10)가 구성되고, 송수신되는 음성신호를 적당한 크기로 증폭시키는 제1증폭기(11)및 제2증폭기(12)가 상기 트랜스(10)의 일단및 타단에 연결되며, 상기 제1및 제2증폭기(11) (12)에는 다수개의 저항소자(R)가 연결된다.In the drawing, a hybrid transformer 10 for separating a voice signal 1 transmitted and received is configured, and a first amplifier 11 and a second amplifier 12 for amplifying the voice signal transmitted and received to an appropriate size are arranged in the transformer 10. Is connected to one end and the other end, and a plurality of resistors R are connected to the first and second amplifiers 11 and 12.

본 발명의 키폰 전화기 시스템을 총괄 제어하는 CPU(20)가 구성되며, 상기 CPU(20)의 콘트롤에 필요한 입출력에 연결시키는 제1및 제2아날로그 스위치IC(21) (22)가 상기 제1및 제2증폭기(11)(12)와 상기 CPU(20)의 일단 및 타단에 연결된다.A CPU 20 for overall control of the key-phone telephone system of the present invention is constructed, and the first and second analog switch ICs 21 and 22 for connecting to the input / output required for the control of the CPU 20 are first and second. The second amplifiers 11 and 12 are connected to one end and the other end of the CPU 20.

그리고, 상기 제1아날로그스위치IC(21)와 CPU(20) 사이에는 필요한 안내메세지(예를들어“지금 부재중이오니”)를 디지탈 코드로 저장시켜 놓는 음성녹음IC (30)와 키폰에 필요한 톤 및 다이얼을 만들어내는 DTMF다이얼부(40)가 콘덴서(C1)를 통하여 연결되며, 핸드세트 송화감(26)에 제3증폭기(13)를 통해 상기 제1아날로그스위치IC(21)에 연결된다.Then, between the first analog switch IC 21 and the CPU 20, the voice recording IC 30 and the tone required for the key phone, which store necessary guidance messages (for example, "I'm not present") as digital codes, are stored. And a DTMF dial portion 40 for making a dial is connected through a condenser C 1 , and is connected to the first analog switch IC 21 through a third amplifier 13 to a handset talk feeling 26. .

상기 제2아날로그스위치IC(22)와 상기 CPU(20) 사이에는 입력된 다이얼톤을 구분하여 상기 CPU(20)가 읽을 수 있도록 4비트 2진코드로 전환시켜주는 DTMF리시버 (50)가 콘덴서(C2)를 통하여 연결되고, 제4증폭기(14)를 통하여 핸드세트 수화감 (27)이 연결된다.Between the second analog switch IC 22 and the CPU 20, a DTMF receiver 50 which distinguishes an input dial tone and converts it into a 4-bit binary code so that the CPU 20 can read it is a capacitor ( C 2 ), and handset hydration 27 is connected via a fourth amplifier 14.

상기 CPU(20)에는 부재중/수신거부표시 및 남겨진 메세지수와 저장된 전화번호를 표시해주는 LCD표시판(60)이 연결되며, 부재중/수신거부 버튼 스위치(70)가 연결된다.The CPU 20 is connected to the LCD display panel 60 which displays the missed / unsubscribe display and the number of messages left and the stored telephone number, and the missed / unsubscribe button switch 70 is connected.

이하 이들의 동작 및 작용 효과를 설명한다.The operation and effect of these will be described below.

사용자가 부재중/수신거부 버튼 스위치(70)를 누르면 CPU(20)가 이를 감지하여 LCD표시판(60)에 그 상태를 표시하고, 이후 착신되는 전화에 대해서는 제1아날로그스위치IC(21)가 송신용 제1증폭기(11)의 입력을 음성녹음IC(30)에 연결시키며, 상기 CPU(20)가 상기 음성녹음IC(30)를 인에이블 시키면 상기 음성녹음IC(30)에 녹음된 안내메세지가 상기 제1아날로그스위치IC(21)와 제1증폭기(11)및 하이브리드 트랜스(10)를 거쳐 상대방에게 전송된다.When the user presses the missed / receive button switch 70, the CPU 20 detects this and displays the state on the LCD panel 60. Then, the first analog switch IC 21 transmits the incoming call. The input of the first amplifier 11 is connected to the voice recording IC 30, and when the CPU 20 enables the voice recording IC 30, a guide message recorded in the voice recording IC 30 is displayed. The first analog switch IC 21 and the first amplifier 11 and the hybrid transformer 10 are transmitted to the counterpart.

이때 상대방은 상기 전송된 안내메세지에 따라 자기전화번호 및 입력 끝 표시버튼(통상전화기의 *버튼)을 누르면 그 입력신호는 상기 하이브리드 트랜스(10)와 제 2증폭기(12)및 제 2아날로그스위치IC(22)를 거쳐 상기 DTMF리시버(50)에 입력된다.At this time, when the other party presses his / her telephone number and input end display button (* button of the normal telephone) according to the transmitted message, the input signal is the hybrid transformer 10, the second amplifier 12 and the second analog switch IC. Inputted to the DTMF receiver 50 via (22).

그러면, 상기 DTMF리시버(50)가 입력된 해당신호 다이얼을 구분하여 4비트 2진수로 변환시켜 상기 CPU(20)로 전송한다.Then, the DTMF receiver 50 classifies the corresponding signal dial and converts the signal into a 4-bit binary number and transmits it to the CPU 20.

그러면 상기 CPU(20)가 이를 감지하여 내부 메세지로 저장시킨다.The CPU 20 then detects this and stores it as an internal message.

상기 마지막 입력끝 표시(*표시) 신호가 상기 CPU(20)에 감지되면 상기 CPU(20)는 통화끝 데이타를 키폰 주장치로 데이타 전송선(도시되지 않음)을 통해 전송시키고 상기 제 1및 제 2아날로그스위치IC(21)(22)를 원래 위치로 복귀시킨 다음 상기 LCD표시판(60)에 표시된 메세지 숫자를 하나 증가시키게 된다.When the last input end indication (* mark) signal is detected by the CPU 20, the CPU 20 transmits call end data to a key phone main unit through a data transmission line (not shown) and the first and second analogues. After the switch ICs 21 and 22 are returned to their original positions, the number of messages displayed on the LCD panel 60 is increased by one.

상기 LCD표시판(60)에 표시된 메세지 숫자는 부재/수신거부중 남겨진 총 전화번호 갯수로서 해당 숫자(Address)에 그 숫자로 증가된 당시의 전화번호가 기억되며, 전화번호 재생시 재생을 위한 버튼 및 어드레스를 다이얼 하면 상대방 전화번호가 상기 LCD표시판(60)에 나타난다.The message number displayed on the LCD panel 60 is the total number of phone numbers left / absent of the reception / reception, and the telephone number at the time of being increased by the number is stored in the corresponding address. When the address is dialed, the other party's telephone number is displayed on the LCD panel 60.

그러면 LCD표시판(60)에 부재/수신거부가 표시된 상태에서 상기 부재/수신거부 버튼스위치(70)를 누르면 상기 LCD표시판(60)에서 부재/수신거부 표시가 지워지고 일반적인 착신기능으로 되돌아간다.Then, when the member / receiver rejection button switch 70 is pressed while the member / receiver is displayed on the LCD panel 60, the member / receiver rejection display is erased from the LCD panel 60 and the normal call back function is returned.

이상에서 설명한 바와 같이 본 발명은 부재중에도 착신된 상대방 전화번호를 알 수 있으므로 쉽게 재통화가 가능하며, 필요시 전화번호를 확인하여 재통화가 가능하므로 특히 장난전화를 방지할 수 있는 유용한 효과가 있다.As described above, the present invention can be easily re-call because it can know the other party's incoming phone number, even if you do not have a useful effect to prevent prank call, especially if you can re-call by checking the phone number. .
