Abstract

본 발명은 팩시밀리가 수동수신상태로 되어 있을때 송신측에서 수신측을 제어하여 수신자 부재시에도 송신측의 원고를 수신할 수 있도록 하는 팩시밀리 수신장치 및 수신방법에 관한 것으로, 중앙처리장치(1)는 수동수신상태에서 착신음이 설정된 횟수만큼 울리면 CML릴레이(3)를 라인 트랜스포머(4)측으로, 아날로그 스위치(9)는 DTMF 디코더(10)측으로 절환시키고, 설정된 시간내에 송신측으로부터 MF 톤신호가 입력되 었는지를 판별하며, 입력신호가 특정신호나 기억된 전화번호일 경우에는 아날로그 스위치(9)를 수신저역통과 필터(7B)로 절환시켜 정상수신동작을 하고, 설정시간내 MF 톤신호가 입력되지 않거나 입력신호가 기억된 내용이 아닐 경우에는 CML릴레이(3)를 핸드셋측으로, 아날로그 스위치(9)는 수신저역통과 필터(7B)측으로 각각 절환시킨 후 종료하게 된다.The present invention relates to a facsimile receiving device and a receiving method for controlling the receiving side at the receiving side when the facsimile is in the manual receiving state so that the original can be received even in the absence of the recipient. When the ringing tone rings in the reception state, the CML relay 3 is switched to the line transformer 4 side, the analog switch 9 is switched to the DTMF decoder 10 side, and the MF tone signal has been input from the transmitting side within the set time. If the input signal is a specific signal or a stored telephone number, the analog switch 9 is switched to the reception low pass filter 7B for normal reception, and no MF tone signal is input or input within the set time. If the signal is not stored, switch the CML relay 3 to the handset side and the analog switch 9 to the receive low pass filter 7B side. It is.
