본 발명은 잉크를 분사시켜 소정의 화상 또는 문자를 프린트하는 잉크제트 프린터에 있어서, 프린트를 하지 않을 경우에 잉크를 분사시키는 노즐을 슬라이드판으로 가로막아 노즐부위의 잉크가 마르면서 막히는 것을 방지 할 수 있게 한 잉크제트 프린터의 노즐 막음장치에 관한 것이다.The present invention provides an ink jet printer in which ink is ejected to print a predetermined image or character, and when the printer is not printed, a nozzle for ejecting ink is blocked by a slide plate to prevent the ink on the nozzle portion from drying out. It relates to a nozzle blocking device of an ink jet printer.

종래의 잉크제트 프린터에도 프린트를 하지 않을 경우에 노즐부위의 잉크가 마르지 않게하여 노즐이 막히지 않게 한 여러가지의 장치가 있는 바, 그 일예를 들면, 잉크제트 장치에 별도의 캐핑장치(Capping device)를 설치하고, 프린트를 하지 않을 경우에는 그 캐핑장치에 잉크제트 헤드를 안착시킨 후 노즐부위에 수증기를 계속 공급함으로써 잉크가 마르는 것을 방지하여 노즐이 막히지 않게 하는 것으로, 이와같은 장치는 별도로 캐핑장치를 설치해야 되고, 또한 수증기를 계속 공급하기 위한 별도의 탱크를 설치해야 되므로 잉크제트 프린터의 크기가 매우 커지게 되는 결함이 있었다.Conventional ink jet printers do not print, but there are various devices that prevent the nozzles from clogging because the ink on the nozzles does not dry out. If the printer does not print, the inkjet head is seated in the capping device, and water vapor is continuously supplied to the nozzle area to prevent the ink from drying out so that the nozzle is not clogged. In addition, there is a defect that the inkjet printer becomes very large because a separate tank for continuously supplying water vapor must be installed.

따라서 본 발명의 목적은 프린트를 하지 않을 경우에 슬라이드판으로 노즐을 가로막아 잉크가 마르는 것을 방지하고, 프린트를 할 경우에는 슬라이드판을 이동시켜 그 슬라이드판에 형성된 통공과 노즐이 일렬로 위치되게 함으로써 노즐을 통해 잉크를 분사시킬 수 있게 하는 간단한 구성의 장치를 제공하는데 있다.Accordingly, an object of the present invention is to prevent the ink from drying out by blocking the nozzle with a slide plate when not printing, and when printing, the nozzle is moved by moving the slide plate so that the holes and nozzles formed on the slide plate are positioned in line. It is to provide a device of a simple configuration that can eject the ink through.

이와같은 본 발명의 목적은 노즐의 전방에 직사각형의 안내공이 형성된 안내판을 설치하고, 그 안내판의 안내공에는 일측에 압전소자가 부착된 슬라이드판을 설치하여 그 압전소자의 동작에 따라 슬라이드판이 이동되게 함으로써 달성될 수 있다.The object of the present invention is to provide a guide plate formed with a rectangular guide hole in front of the nozzle, the guide plate of the guide plate is provided with a slide plate with a piezoelectric element attached to one side so that the slide plate is moved according to the operation of the piezoelectric element. This can be achieved by.

이하, 첨부된 도면에 의하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명 노즐 막음장치의 분해 사시도로서, 이에 도시한 바와같이 잉크실벽(1)에 설치된 노즐판(2)의 전방에 노즐(2')보다 큰 3개의 정방형 통공(3')이 일정간격으로 천공된 중간판(3)을 설치하여 그 통공(3')과 노즐(2')이 연통되게 하고, 중간판(3)의 전방에는 길이 방향으로 장방향 안내공(4')이 천공된 안내판(4)을 설치하여 그 안내공(4')의 일측에는 압전소자(5)의 일측을 고정하며, 압전소자(5)의 타측에는 3개의 정방형 통공(6')이 일정간격으로 천공된 슬라이드판(6)을 설치하여 그 슬라이드판 (6)이 안내공(4')을 따라 타측으로 이동되었을때 그 통공(6')이 통공(3') 및 노즐(2')과 연통되게 하는 한편, 안내판(4)의 전방에는 일정길이의 장방형 통공(7')이 길이 방향으로 천공된 전면판(7)을 설치하여 상기 슬라이드판(6)이 안내공(4')에서 이탈되는 것을 방지하게 구성한 것으로 상기에서 압전소자(5)에는 잉크제트 프린터에 동작 전원을 인가하였을때 펄스 전압이 인가되게 하여 길이 방향으로 팽창되게 한다.1 is an exploded perspective view of the nozzle blocking device of the present invention, in which three square through-holes 3 'larger than the nozzles 2' are fixed in front of the nozzle plate 2 provided on the ink chamber wall 1, as shown in FIG. Intermediate plate 3 perforated at intervals is provided so that the through hole 3 'and the nozzle 2' communicate with each other, and the longitudinal guide hole 4 'in the longitudinal direction is drilled in front of the intermediate plate 3 in the longitudinal direction. One side of the piezoelectric element 5 is fixed to one side of the guide hole 4 ', and three square through holes 6' are drilled at regular intervals on the other side of the piezoelectric element 5; Mounted slide plate 6 so that when the slide plate 6 is moved along the guide hole 4 'to the other side, the through hole 6' communicates with the through hole 3 'and the nozzle 2'. Meanwhile, in front of the guide plate 4, a front plate 7 having a predetermined length of rectangular through hole 7 ′ is drilled in the longitudinal direction is installed so that the slide plate 6 is separated from the guide hole 4 ′. Prevention When it is configured as hayeoteul in the piezoelectric element 5 is applied to the operating power supply to the ink jet printer to be a pulse voltage is applied to causes expansion in the longitudinal direction.

이와같이 구성된 본 발명의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effects of the present invention configured as described above.

잉크제트 프린터에 동작 전원을 인가하지 않았을 경우에는 압전소자(5)에 펄스 전압이 인가되지 않아 팽창되지 않게 되므로 슬라이드판(6)이 이동되지 않게 되어 제2도의 (a)에 도시한 바와같이 슬라이드판(6)의 통공(6')이 중간판(3)에 형성된 통공 ( 3') 및 노즐판(2)의 노즐(2')과 연통되지 않고 약간 어긋나게 위치되어 통공(3') 및 노즐(2')이 외부로 노출되지 않게 되므로 잉크가 마르는 것이 방지되어 통공(3') 및 노즐(2')이 막히는 것이 방지된다.When the operating power is not applied to the ink jet printer, the pulse voltage is not applied to the piezoelectric element 5 so that the slide plate 6 does not move, and thus the slide plate 6 does not move and slides as shown in FIG. The through hole 6 'of the plate 6 is positioned slightly shifted without communicating with the through hole 3' formed in the intermediate plate 3 and the nozzle 2 'of the nozzle plate 2, so that the through hole 3' and the nozzle Since the 2 'is not exposed to the outside, the ink is prevented from drying, and the passage 3' and the nozzle 2 'are prevented from being blocked.

한편 프린트를 하기 위하여 잉크제트 프린터에 동작 전원을 인가하면, 압전소자 (5)에 펄스 전압이 인가되어 안내공(4')을 따라 길이 방향으로 팽창운동을 하게 되므로 슬라이드판 (6)이 안내공(4')을 따라 타측으로 이동하게 되고, 이에 따라 제2도의(b) 및 제3도에 도시한 바와같이 슬라이드판(6)의 통공(6')이 중간판(3)의 통공(3') 및 노즐판(2)의 노즐(2')과 일렬로 위치되어 연통되게 되므로 잉크 유입관(8)을 통해 잉크실(9)에 유입되는 잉크를 노즐(2')을 통해 분사시킬 수 있게 된다.On the other hand, when the operating power is applied to the ink jet printer for printing, a pulse voltage is applied to the piezoelectric element 5 so as to expand in the longitudinal direction along the guide hole 4 '. (4 ') is moved to the other side, so that the through hole 6' of the slide plate 6 as shown in (b) and 3 of FIG. ') And the nozzle 2' of the nozzle plate 2 are positioned in line with each other so that the ink flowing into the ink chamber 9 through the ink inflow pipe 8 can be injected through the nozzle 2 '. Will be.

그리고, 프린트를 완료한 후 잉크제트 프린터에 인가된 동작 전원을 차단시키면 압전소자(5)에도 인가된 펄스 전압이 차단되어 원상복귀 즉, 수축하게 되므로 슬라이드판(6)이 원상복귀되어 상기에서와 같이 슬라이드판(6)의 통공(6')이 통공(3') 및 노즐 (2')과 약간 어긋나게 되고, 이에 따라 잉크가 마르는 것이 방지되어 노즐(2')이 막히는 것이 방지되는 것이다.When the operation power applied to the ink jet printer is cut off after the printing is completed, the pulse voltage applied to the piezoelectric element 5 is also cut off, so that the slide plate 6 returns to its original state. Likewise, the through hole 6 'of the slide plate 6 is slightly displaced from the through hole 3' and the nozzle 2 ', thereby preventing the ink from drying out and preventing the nozzle 2' from being clogged.

이상에서 설명한 바와같이 본 발명은 잉크가 말라 노즐이 막히는 것을 방지하는 간단한 구성의 장치로 잉크제트 프린터의 크기를 소형화 시킬 수 있게 되는 효과가 있다.As described above, the present invention has an effect of miniaturizing the size of the ink jet printer with a device having a simple configuration that prevents the ink from drying out and clogging the nozzle.
