Abstract

그레이 스케일(grey scale)로 인쇄 가능한 버블제트(buble jet) 프린터에 관한 내용이 개시되어 있다. 이 프린터는 미리 정해진 형상의 노즐구멍(31)이 형성된 노즐플레이트(30)와, 노즐플레이트와 상호 결합되어 잉크가 공급되는 소정 형상의 캐비티(50)를 형성하는 기판(40)과, 기판에 부착되며 소정의 전류가 인가되는 복수의 전극(70)과, 복수의 전극과 적절히 연결되고 크기가 다른 복수의 발열체(61-66)가 적층 배열된 발열유니트(60)를 구비하여 된 구조를 가진다. 이는 가열되는 발열체의 면적에 따라 토출되는 잉크방울의 크기가 제어된다.Disclosed is a bubble jet printer capable of printing in gray scale. The printer includes a nozzle plate 30 having a nozzle hole 31 of a predetermined shape, a substrate 40 which is coupled to the nozzle plate to form a cavity 50 of a predetermined shape to which ink is supplied, and is attached to the substrate. And a plurality of electrodes 70 to which a predetermined current is applied, and a heating unit 60 in which a plurality of heating elements 61 to 66 different in size and properly connected to the plurality of electrodes are stacked and arranged. The size of the ink droplets discharged is controlled according to the area of the heating element to be heated.
