Claims (13)

  1. 잉크 제트 프린팅 장치는 잉크저장소와, 부압(negative pressure)을 제거하고 저장소로 부터 잉크를 배출 하기위한 프린트헤드와, 제어가능한 도입 대체로 유체(즉, 공기나 잉크)에 의해 잉크로 저장소내에서 부압을 제한하기 위한 제1압력 제어기구와, 체적을 변화함에 의해 잉크 저장소내외 부압을 제한하기 위한 제2압력 제어기구를 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  2. 제2항에 있어서, 제2압력 제어 기구는 저장소내의 압력에 상응하여 움직일수 있는 부재를 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  3. 제2항에 있어서, 한계값 이하의 잉크 저장소에서 부압(negative pressure)의 행정에 대하여 제1압력 제어 기구는 작동하지 않는 것을 특징으로 하는 잉크 제트 프린팅장치.
  4. 제2항에 잇어서, 가동 부재는 저장소의 체적을 증가하도륵한 편향 수단을 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  5. 제1항에 있어서, 제1압력 제어기구는 그 안에 부압(negative pressure)이 한계값을 통과한 후 잉크 저장소로 대체 유체를 도입하기위한 수단을 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  6. 제5항에 있어서, 그물과, 그물에 주위 압력을 적용하는 수단과, 그들 사이의 압력차에 상응하여 그물로 부터 유체를 인출할수 있는 잉크 저장조를 통하여 유체경로를 설정한 오리피스를 형성하는 수단과, 잉크 저장소내의 압력이 주위 압력에 완전히 도달하는 것을 방지하기위한 그물로 부터 잉크 저장소 안으로 유체의 흐름 을 제한하기 위한 압력 레귤레이터 수단을 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  7. 잉크 제트 프린팅장치는 잉크를 수용하기위한 잉크 저장소와, 그물과 주위 압력으로 그물을 유지하기 위한 수단과. 그들 사이에 충분한 압력차가 존재할 때 저장소로 부터 그물로 배출된 잉크를 통하여 유체 경로를 설정하기 위한 오리피스 수단과, 잉크 저장조의 체적을 변화하고, 제1범위에서 압력에 의해 그물로 오리피스 수단을 통하여 잉크가 구동되는 것을 방지자도록 저장소내의 압력을 해제하기 위하여 저장소압력의 제1범위를 지나 작동하는 가동수단을 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  8. 제7항에 있어서, 가동수단은 체적을 변화하기위하여 잉크저정소내의 압력에 상응한 수단을 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  9. 잉크 제트 프린팅 장치는 가동부재를 구비한 잉크 저장소를 포함하고, 상기 가동부재는 잉크가 배출되므로 저장소 체적을 수축하며, 체적내에서 수축은 가동부재가 그 이동을 재한하 때까지 저정소내의 부압을 제한 하고, 장치가 더이상 배출하지 않을 때까지 저장소내의 부압이 증가하며, 상기 장치는 가동부재가 그 이동의 제한치에 도달한후 장치에 계속 프린트하도록 유체를 자동으로 도입하기 위한 잉크저장소내에 압력에 상응한 구멍을 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  10. 제9항에 있어서, 구멍은 장치가 전환된다면 저장소 안으로 공기의 제한되지 않은 도입을 방지하기 위한 밸브 수단을 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  11. 잉크 제트 프린팅장치는 가변 체적 부분보다 고정 체적 부분이 크며, 가변 체적부분과 고정 체적부분을 구비한 저정소와, 부압을 회피하고, 저정소로 부터 잉크 배출하기 위한 프린트 헤드와. 압력에 상응하여 가변 체적 부분의 체적을 변화하기 위한 수단과, 압력에 상응하여 저정소내의 유체의 체적을 변화하기 위한 수단을 포함하는 것을 특징으로 하는 잉크 제트 프린팅장치.
  12. 잉크를 수용하기 위한 저장소를 포함하며 잉크 재트펜을 작동하기 위한 방법에 있어서, 작동이 제1국면 동안 저장소의 크기를 변화함에 의해 저장소 압력 이하를 조정하는 단계와, 작동의 제2국면동안 거기에 공기를 도입함에 의해 저정소 압력 이하를 조정하는 단계를 포함하는 것을 특징으로 하는 잉크 재트펜을 작동하기 위한 방법.
  13. 제12항에 있어서, 작동의 제3국면동안 저장소로 부터 그물로 잉크를 전달함에 의해 저장소 압력을 제한 하는 단계를 포함하는 것을 특징으로 하는 방법.
