Abstract

본 발명은 다수개의 컴퓨터에 1개의 프린터를 공유하여 사용하고자 할 경우에 사용되는 프린터 공유기에 있어서, 종래에는 공유되고 있는 컴퓨터의 어느 하나를 ON, OFF시킬 경우에 발생되는 순간적인 노이즈로 인하여 해당 컴퓨터의 공유기가 다운되면서 오동작으로 인하여 다른 공유기에 영향을 미치게 되어 프린터에 원인을 알 수 없는 오동작이나 이상한 글자가 인쇄되는 현상이 발생되는 문제점이 있었으나 본 발명은 이러한 문제점의 해결을 위한 안정화회로에 관한 것이다.The present invention relates to a printer sharing device used when sharing a single printer to a plurality of computers and to use the same. In the past, due to the instantaneous noise generated when turning on or off any one of shared computers, There is a problem that a malfunction or a strange character is printed on the printer due to a malfunction due to a malfunction of the router due to a failure of the router, and the present invention relates to a stabilization circuit for solving such a problem .

이를 위하여 프린터포트에서 나오는 INIT단자를 공유기의 CPU와 연결하여 줌으로서 컴퓨터가 OFF되면 INIT단자가 LOW로 떨어지는 것을 이용하여 공유기의 CPU가 초기화가 않되도록 하여 동작을 못하도록 막으며 또한 컴퓨터를 ON시키면 컴퓨터에서 BIOS를 읽은후 INIT가 HIGH가 되므로 컴퓨터의 ON시에 순간적인 오동작을 방지할 수 있으며 INIT선이 STRB의 입력단자에 병렬로 연결되어 컴퓨터가 완전히 동작을 해야만 컴퓨터에서 보내는 데이타를 처리할 수 있게 한 것이다.To do this, connect the INIT terminal from the printer port to the CPU of the router. If the computer is turned off, the INIT terminal goes down to LOW to prevent the CPU of the router from being initialized. , The INIT becomes HIGH after reading the BIOS in BIOS. Therefore, the INIT line is connected in parallel to the input terminal of STRB so that the computer can operate completely when the computer is turned on. It is.
