다중입력 프린터의 제어회로Control circuit of multi-input printer

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 다중입력 프린터의 제어회로에 대한 전체 블럭도,1 is an overall block diagram of a control circuit of a multi-input printer of the present invention;

제2도는 인터페이스부(1I-4I)중에서 하나를 예로하여 상세 표현한 회로도,2 is a circuit diagram detailing one of the interface units 1I-4I as an example;

제3도는 표시부(6)의 일실시 예시도.3 is an exemplary view of the display unit 6.

Claims (2)

각각의 제1-4PC(1-4)를 제1-4인터페이스부(I1-4I)를 각기 통해 프린터(5)에 공통으로 접속하되, 상기 제1PC(1)피 스트로브신호(STB)와 상기 프린터(5)의 프린터 온신호(PE)를 논리조합하어 그 프린터(5)에 스트로브신호(STB)를 공급하는 스트로브신호 출력부(Id)와, 상기 스트로브신호 출력부(Id)의 출력신호와 상기 프린터(5)의 비지신호(BUSY)를 디코딩한 후 이를 상기 제1PC(1)의 비지신호(BUSY)로 제공하는 디코딩부(le)와, 제1-4PC(1-4)중에서 하나의 PC에서 이미 스트로브 신호(STB)가 출력되었을때 다른 PC의 스트로브신호(STB)출력을 차단하는 스트로브신호 제어부 (1f)로 상기 제1인터페이스부(1I)를 구성하고, 이와같이 제2-4인터페이스부(2I4I)를 구성한 것을 특징으로 하는 다중입력 프린터의 제어회로.Each of the first to fourth PCs 1-4 is commonly connected to the printer 5 through the first to fourth interface units I1-4I, respectively, and the first PC 1 strobe signal STB and the The strobe signal output unit Id for logically combining the printer on signal PE of the printer 5 and supplying the strobe signal STB to the printer 5, and the output signal of the strobe signal output unit Id; A decoding unit le for decoding the busy signal BUSY of the printer 5 and providing it as the busy signal BUSY of the first PC 1 and one of the first to fourth PCs 1-4. When the strobe signal STB has already been output from the PC, the strobe signal controller 1f blocks the output of the strobe signal STB of another PC. A control circuit for a multi-input printer, comprising (2I4I). 제1항에 있어서, 인터페이스부(1I-4I)의 스트로브신호(A-D)를 논리조합하여 현재 프린터(5)틀 사용하고 있는 PC의 번호를 표시하게 표시부(6)를 구성한 것을 특징으로 하는 다중입력 프린터의 제어회로.2. The multiple input according to claim 1, wherein the display unit 6 is configured to logically combine the strobe signals AD of the interface units 1I-4I to display the number of the PC currently using the printer 5. Control circuit of the printer. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
