Abstract

잉크 레벨 검출 장치(14)는 잉크-젯 펜에 의해 사용되는 잉크 서플라이를 저장하기 위한 유연성 잉크 용기(16)를 갖는다. 잉크 용기(16)는 그 내에 있는 잉크양에 따라 서로에 대해 이동하는 대향 측면(20,22)를 갖는다. 또한, 잉크 레벨 검출 장치(14)는 잉크 용기(16)에 대향 측면상에 형성된 한쌍의 전기 전도성 코일(30,32)을 갖는다. 상기 코일(30,32)은 유연성 용기(16)의 대향 측면상의 움직임에 따라 서로에 대해 이동한다. 잉크 레벨 감지 회로(50)는 코일(30,32)과 연결되어 있다. 잉크 레벨 감지 회로(50)는 한쌍의 코일(30,32) 사이에 전자계를 유도하는 신호를 발생한다. 또한, 잉크 레벨 감지 회로는(50)는 코일(30,32)이 서로에 대해 이동할 때의 전자계의 변화를 검출하므로서 잉크 용기(16)내의 잉크 레벨을 감지한다. 코일(30,32)이 서로 가까이 접근함에 따라 전자계의 세기가 증가하며, 이에 의해 잉크가 용기(16)에서 고갈될 때를 양호하게 측정할 수 있다.

  5. 잉크 레벨 검출기에 있어서, 잉크통의 대향 측면에 설치되고, 상기 잉크통의 잉크 레벨과 관련해서 서로에 대해 이동하는 한쌍의 전기 전도성 코일(30,32)과, 한쌍의 코일(30,32)사이에 전자계를 유도하고, 코일이 서로에 대해 이동할 때 전자계의 변화를 검출하므로서 잉크통의 잉크 레벨을 감지하도록 코일에 연결된 잉크 레벨 감지 회로(50)를 포함하는 잉크 레벨 검출기.
  6. 제5항에 있어서, 상기 신호가 제1코일(30)에 공급되고, 전압은 전자게에 의해 제2코일(32)에서 유도되는 잉크 레벨 검출기.
  7. 제5항에 있어서, 상기 코일(30,32)은 직렬로 연결되는 잉크 레벨 검출기.
  8. 제5항에 있어서, 상기 전자계는 상기 코일(30,32)이 서로 근접함에 따라 세기가 증가하는 잉크 레벨 검출기.
  9. 제1항 내지 제8항 중 어느 한 항에 따른 잉크 레벨 검출기를 포함하는 잉크 공급 카트리지.
  10. 제1항 내지 제8항 중 어느 한 항에 따른 잉크 레벨 검출 장치를 포함하는 잉크-젯 펜.
