Abstract

PURPOSE: An ink injector of an ink jet printer is provided to simplify structure and to reduce a consumption amount of ink. CONSTITUTION: An ink injector of an ink jet printer comprises plural power; plural conductive beams forming each closed circuit and connecting to the power; a magnet installed on upper and lower parts of the conductive beams; and an ink chamber(14) forming a space between every conductive beam to contain ink. As the magnets (12,13) are prepared on the upper and lower parts of the plural beams(11,11'), a current is flowed to the beam so that an electromagnetic force is generated in the rectilinear direction of the magnet. Thus, each beam is deflected to the left or the right according to the direction of a current flow. Further, the ink contained between the beams is discharged to a front part.

Description

잉크젯 프린터의 잉크 분사 장치{APPARATUS FOR DISCLOSING INK OF INKJET PRINT}Ink jetting device of inkjet printer {APPARATUS FOR DISCLOSING INK OF INKJET PRINT}

본 발명은 잉크젯 프린터의 잉크 분사 장치에 관한 것으로, 특히 전자기력에 의하여 작동되는 원 빔(one beam)형 도체를 이용하여 잉크를 연속적으로 분사하도록 한 잉크젯 프린터의 잉크 분사 장치에 관한 것이다.TECHNICAL FIELD The present invention relates to an ink jetting apparatus of an inkjet printer, and more particularly, to an ink jetting apparatus of an inkjet printer in which ink is continuously jetted by using a one beam type conductor operated by electromagnetic force.

종래의 드롭 온 디멘드(drop on demand) 방식의 잉크젯 프린터의 헤드에 적용된 기술은 도 1에 도시한 바와 같이, 압전체(1)를 이용한 피에조 타입을 사용한 엡슨(Epson)사의 경우와, 도 2 및 도 3에 도시한 바와 같이, 발열체(2)에서 발생한 열을 이용하여 잉크(I)를 토출하는 서멀(thermal)방식을 채용한 휴렛패커드사, 캐논사의 경우로 대별할 수 있다. 그 밖에 자기력, 정전기력을 이용한 연속분사방식의 카트리지가 제공되기도 하였다.The technology applied to the head of a conventional drop on demand inkjet printer is as shown in Fig. 1, Epson (Epson) using a piezo type using the piezoelectric body 1, Figs. As shown in Fig. 3, it can be roughly classified into the case of Hewlett Packard and Canon, which employs a thermal method in which the ink I is discharged by using the heat generated by the heat generator 2. In addition, a cartridge of a continuous injection method using magnetic force and electrostatic force has been provided.

압전방식에 의한 잉크의 분사방식은 압전체(1)에 구동신호를 가하여 변위를 발생시킴으로써 이러한 변위가 잉크(I)에 전달되어 잉크가 토출되는 방식이며, 서멀방식은 구동신호를 전극을 통해 전달함으로써 저항이 큰 발열체(2)를 통과할 때, 잉크(I)가 끊는 정도의 열을 발생시켜 이러한 열에 의하여 잉크에 발생되는 기포가 잉크(I)를 밀어냄으로써 잉크를 토출시키는 방식이다.Piezoelectric ink is a method of ejecting ink by applying a drive signal to the piezoelectric body 1 to generate a displacement, such that the displacement is transferred to the ink I and the ink is ejected, and the thermal method transmits a drive signal through an electrode. When passing through the heat generating element 2 having a large resistance, heat generated to the extent that the ink I breaks, and bubbles generated in the ink by this heat push the ink I to eject the ink.

한편, 도 4에 도시한 바와 같은, 자기력과 정전기력을 이용하여 영구자석(3)과 박막코일(4)을 사용한 연속분사방식은 도전성 잉크(I)를 연속적으로 분사시키고, 구동신호에 따라 자기력과 정전기력을 발생시켜 잉크 방울의 진로를 변경시켜 인쇄하는 방식이다.On the other hand, as shown in Figure 4, the continuous injection method using the permanent magnet (3) and the thin film coil (4) by using the magnetic force and the electrostatic force to continuously spray the conductive ink (I), according to the drive signal and the magnetic force It prints by changing the path of ink drop by generating electrostatic force.

그러나 피에조 방식에 의한 잉크 분사 방식은 프린팅 속도가 늦고, 헤드당 노즐의 수를 많이 형성할 수 없으며, 헤드의 가격이 고가이기 때문에 양산 수율이 저조하다는 문제가 있다.However, the ink jet method by the piezo method has a problem in that the printing speed is low, the number of nozzles per head cannot be formed, and the mass production yield is low because the price of the head is high.

또한, 서멀 방식은 헤드의 수명이 짧고, 해상도가 떨어지며, 잉크의 호환성이 저조하고, 구조가 복잡하다는 문제가 있다.In addition, the thermal method has a problem that the life of the head is short, the resolution is low, the compatibility of ink is poor, and the structure is complicated.

그리고 자기력과 정전기력을 이용한 잉크 분사 방식은 인쇄속도가 빠르다는 장점을 갖는 반면에 잉크의 소모량이 많고, 경제성이 떨어진다는 단점이 있다.In addition, the ink jetting method using magnetic force and electrostatic force has the advantage that the printing speed is high, while the ink consumption is high and the economical disadvantage is low.

이와 같은 여러 가지 문제점을 감안하여 안출한 본 발명의 목적은 간소한 구조를 갖는 잉크젯 프린터의 잉크 분사 장치를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention devised in view of such various problems is to provide an ink jetting apparatus of an ink jet printer having a simple structure.

본 발명의 다른 목적은 정확한 잉크 분사 동작을 구현하여 잉크의 소모량을 줄이도록 한 잉크젯 프린터의 잉크 분사 장치를 제공함에 있다.Another object of the present invention is to provide an ink jetting apparatus of an ink jet printer, which realizes an accurate ink jetting operation to reduce the consumption of ink.

이하, 상기한 바와 같은 본 발명의 바람직한 실시예를 첨부도면에 의거하여 보다 상세히 설명한다.Hereinafter, preferred embodiments of the present invention as described above will be described in more detail with reference to the accompanying drawings.

첨부도면 도 5는 본 발명에 의한 잉크 분사 방식의 구성을 개략적으로 보인 사시도이고, 도 6은 도 5의 개략적인 구성도이며, 도 7은 도 5의 배면도이고, 도 8은 잉크 분사시의 상태를 연속적으로 보인 단면도이다.5 is a perspective view schematically showing the configuration of the ink ejection method according to the present invention, FIG. 6 is a schematic configuration view of FIG. 5, FIG. 7 is a rear view of FIG. 5, and FIG. It is sectional drawing which showed state continuously.

이에 도시한 바와 같이, 본 발명의 실시예는 잉크의 분사 메카니즘을 전자기력에 의한 분사 메카니즘으로 구성하며, 이러한 구체적인 기구의 구성은 상하부에 마그네트(12)(13)가 구비되고, 그 사이에서 전류가 흐르는 도체로서의 단일 빔(11)을 다수 개 배치한 것이다.As shown in the drawing, the embodiment of the present invention constitutes a jetting mechanism of ink by an electromagnetic force, and this specific mechanism is provided with magnets 12 and 13 at the upper and lower sides, and a current therebetween. A plurality of single beams 11 as flowing conductors are arranged.

다수 개의 도체빔(11)(11')(11")(...)은 서로 이웃하는 빔끼리는 전원이 인가되었을 때, 반대방향으로 전류를 흘려주기 때문에 전원에서 공급되는 전류에 의하여 자속의 방향이 변경되어 인접하는 빔들끼리 서로 인력이 작용한다.Since the plurality of conductor beams 11, 11 ', 11 ", (...) flows current in opposite directions when power is applied to neighboring beams, the direction of the magnetic flux is caused by the current supplied from the power source. This change causes the adjacent beams to attract each other.

도체빔은 빔의 일단부에 전원이 연결되어 있고, 타단부에는 전류 경로가 형성되어 전원과 연결됨으로써 폐회로를 구성한다.The conductor beam is connected to a power source at one end of the beam, and a current path is formed at the other end to be connected to the power source to form a closed circuit.

빔(11)(11')(11")(...)의 머리부(11a)와 머리부(11'a) 사이의 틈이 노즐 분사공의 역할을 담당하게 되고, 빔의 몸체와 몸체 사이의 공간이 잉크가 수납되는 잉크 챔버(14)의 역할을 담당한다.The gap between the head portion 11a and the head portion 11'a of the beams 11, 11 ', 11 ", (...) serves as a nozzle spray hole, and the body and the body of the beam The space between serves the ink chamber 14 in which ink is accommodated.

이와 같이 구성되어 있는 본 발명의 작용을 설명한다.The operation of the present invention configured as described above will be described.

본 발명에 의한 도체인 다수 개의 빔(11)(11')(11")(...)의 상하부에 마그네트(12)(13)가 구비되어 있기 때문에 빔에 각각 전류를 흘려주면 마그네트(12)(13)의 직각방향으로 빔에 대하여 전자력이 발생된다.Since the magnets 12 and 13 are provided above and below the plurality of beams 11, 11 ', 11 ", ..., which are conductors according to the present invention, the magnets 12 Electromagnetic force is generated with respect to the beam in a direction perpendicular to the direction (13).

따라서 각각의 빔은 전류의 흐르는 방향에 따라 좌측으로 휘어지거나, 우측으로 휘어지게 되며, 빔과 빔 사이에 수납되어 있는 잉크는 전방으로 토출되는 것이다.Therefore, each beam is bent to the left or to the right according to the direction of current flow, and the ink contained between the beams is discharged forward.

이상에서 설명한 바와 같이, 본 발명에 의한 잉크젯 프린터의 잉크 분사 장치는 전자기력을 이용하여 잉크를 분사하는 방식으로서, 전자력이 발생되는 도체를 단일 빔을 사용하기 때문에 도체의 휨(deflection)이 커지고, 압착력(pressure)도 커져 정확한 잉크의 토출이 이루어지는 효과가 있다.As described above, the ink jetting apparatus of the inkjet printer according to the present invention is a method of injecting ink by using electromagnetic force, and the deflection of the conductor is increased because the single beam is used for the conductor generating the electromagnetic force. (pressure) is also large, there is an effect that the accurate ejection of ink.
