원격조정 컴퓨터용 키보드 회로Keyboard circuit for remote control computer

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

제2도는 본 발명에 따른 원격조정 컴퓨터용 키보드 회로 구성도.2 is a block diagram of a keyboard for a remote control computer according to the present invention.

Claims (1)

컴퓨터용 키보드 회로에 있어서, 키보드(6)로부터 접속되어 MFC 톤을 발생시키는 MFC 톤 발생기(3)와, MFC톤 발생기(3)에 직렬연결된 버퍼(B1및B2)로부터 접속되어 상기 MFC톤을 복호화하고 그에 해당되는 출력선을 선택하여 활성 신호를 출력토록 한 MFC 복호기(4)와, 상기 버퍼(B1및 B2)의 직렬연결점으로부터 접속되어 전화회선과의 임피던스 매칭을 위한 임피던스 매칭트랜스 T와, 상기 MFC복호기(4)로부터의 출력신호에 따라 상기 키보드(6)와 동일한 작용을 하는 아날로그 스위치부(9)로 구성된 것을 특징으로 하는 원격조정 컴퓨터용 키보드 회로.In a computer keyboard circuit, an MFC tone generator 3 connected from a keyboard 6 to generate MFC tones and a buffer B 1 and B 2 connected in series with the MFC tone generator 3 are connected to the MFC tone. Is an impedance matching transformer for impedance matching with a telephone line, connected to the MFC decoder 4 which decodes and selects an output line corresponding thereto, and outputs an active signal from a serial connection point of the buffers B 1 and B 2 . T and an analog switch section (9) having the same function as the keyboard (6) in accordance with an output signal from the MFC decoder (4). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
