Description

디지털 비디오 프린터의 열전사장치Thermal Transfer Device of Digital Video Printer

본 발명은 디지털 비디오 프린터의 열전사장치에 관한 것으로서, 더욱 상세하게는 용지가 열전사헤드(Thermal Print Head : 이하 TPH라 함)를 1회 지나치는 과정에서 R,G,B(Red, Green, Blue) 칼라에 대응되는 화상데이터가 동시에 인쇄되도록 구성하므로써 출력속도를 단축시킬 수 있도록 하고, 내부구조를 단순화 시킬 수 있도록 한 디지털 비디오 프린터의 열전사장치에 관한 것이다.The present invention relates to a thermal transfer apparatus of a digital video printer, and more particularly, R, G, B (Red, Green, in the process of passing the paper once the thermal print head (TPH) once) Blue) The present invention relates to a thermal transfer apparatus of a digital video printer which is configured to print image data corresponding to color simultaneously, thereby reducing output speed and simplifying an internal structure.

일반적으로, 디지털 비디오 프린터에서는 디지털카메라로 촬영한 화상데이터가 R, G, B 삼원색에 대응되는 각각의 데이터로 분류되어 내장된 마이크로 프로세서에 입력되고, 이와 같이 입력된 데이터는 TPH와 열전사리본에 의해 용지에 프린팅되도록 구성된다.In general, in a digital video printer, image data photographed with a digital camera is classified into respective data corresponding to R, G, and B primary colors, and inputted into an embedded microprocessor. By printing on the paper.

이와 같은 프린팅 과정에서 TPH는 하부의 플레튼롤러와 밀착되고, 그 사이로 용지와 열전사리본이 동시에 이송되는 과정에서 상기한 화상데이터에 따라 발열소자가 열을 전사함으로써 입력된 데이터가 출력되는 것이다.In the printing process, the TPH is in close contact with the platen roller at the lower portion, and the input data is output by transferring the heat according to the image data in the process of simultaneously transferring the paper and the thermal transfer ribbon therebetween.

이와 같은 디지털 비디오 프린터에 적용되는 일반적인 열전사리본 카트리지는 다음과 같이 구성된다.A general thermal transfer ribbon cartridge applied to such a digital video printer is configured as follows.

도 1은 일반적인 디지털 비디오 프린터의 열전사리본 카트리지를 나타내는 사시도이고, 도 2는 일반적인 열전사리본 카트리지에 감겨진 열전사리본을 나타내는 평면도이다.1 is a perspective view illustrating a thermal transfer ribbon cartridge of a general digital video printer, and FIG. 2 is a plan view illustrating a thermal transfer ribbon wound around a general thermal transfer ribbon cartridge.

이를 참조하면, 열전사리본(10)은 면상에 상기한 R, G, B 칼라화소가 일정한 간격으로 연속되게 코팅된 비닐계 필름으로서, 수납케이스(12)의 내부에서 일정 간격으로 회동되게 설치된 공급릴(14)과 권취릴(16)에 감겨져 있다.Referring to this, the thermal transfer ribbon 10 is a vinyl-based film in which the above-mentioned R, G, B color pixels are continuously coated at regular intervals, and are installed to be rotated at regular intervals inside the storage case 12. It is wound around the reel 14 and the reel 16.

이와 같은 열전사리본(10)을 이용한 프린팅 작업시 권취릴(16)의 구동에 따라 수납케이스(12) 내부의 공급릴(14)에 감겨진 열전사리본(10)이 풀리면서 권취릴(16)로 이송됨과 동시에, 용지가 그 열전사리본(10)과 밀착된 상태로 통과되면서 상기한 TPH의 발열량에 따라 대응되는 농도로 상이한 칼라의 화소가 용지 표면에 전사되므로써 R, G, B삼원색의 배합에 의해 천연색 칼라 프린팅을 구현할 수 있게 된다.In the printing operation using the thermal transfer ribbon 10, the thermal transfer ribbon 10 wound around the supply reel 14 inside the storage case 12 is unwound as the winding reel 16 is driven and the winding reel 16 At the same time, the paper is passed in close contact with the thermal transfer ribbon 10, and pixels of different colors are transferred to the surface of the paper at a density corresponding to the heat generation amount of the TPH. By combining the color printing can be achieved.

이러한 작업을 위해 상기한 디지탈 비디오 프린터에서는 급지카세트에 채워져 있는 용지가 이송경로를 따라 3회에 걸쳐 왕복이송되도록 구성되고, 이에 따라 상기한 R, G, B 칼라에 대응되는 화상데이터가 순차적으로 인쇄되도록 구성된다.In the above digital video printer, the paper filled in the paper cassette is reciprocated three times along the transfer path, so that the image data corresponding to the R, G, and B colors are sequentially printed. It is configured to be.

그러나, 이와 같은 디지털 비디오 프린터에 적용되는 열전사리본 카트리지에서는 상기한 이송경로 상에 설치된 TPH로부터 일정 거리 이격된 플레튼롤러의 작용에 의하여 이송되는 용지는 열전사리본과 함께 백피딩(Back-Feeding)되면서 해당 칼라에 대응되는 화상데이터를 인쇄하는 등의 순차적인 작업이 필요하게 되며, 이때, 상기한 TPH는 반복적으로 상승 및 하강하도록 구성됨에 따라 출력시간이 오래 걸리고 3회 왕복에 필요한 기구적인 구성이 요구되므로 내부구조가 복잡해진다는 문제가 있다.However, in the thermal transfer ribbon cartridge applied to such a digital video printer, the paper conveyed by the action of the platen roller spaced a certain distance from the TPH installed on the transfer path is back-feeded together with the thermal transfer ribbon. Sequential operation such as printing image data corresponding to the corresponding color is necessary, and the TPH is configured to repeatedly rise and fall, which takes a long time to output and a mechanical configuration required for three round trips. Since this is required, there is a problem that the internal structure becomes complicated.

본 발명의 목적은 용지가 TPH를 1회 통과하는 과정에서 R,G,B 칼라에 대응되는 화상데이터가 동시에 인쇄되도록 구성하므로써 출력속도를 단축시킬 수 있도록 하고 내부구조를 단순화 시킬 수 있도록 한 디지털 비디오 프린터의 열전사장치를 제공하는 것이다.An object of the present invention is to configure the image data corresponding to R, G, and B colors to be printed at the same time during the paper passes through the TPH once, so that the output speed can be reduced and the internal structure can be simplified. It is to provide thermal transfer of printer.

Three independent thermal transfer ribbons 80 in coated form are configured to be wound.

이와 같이 이루어지는 본 발명의 작용을 첨부된 도면에 의하여 설명한다.The operation of the present invention made as described above will be described with reference to the accompanying drawings.

도 5는 본 발명에 따른 열전사장치를 이용하여 화상 데이터를 프린트하는 상태를 나타내는 정면도이다.5 is a front view showing a state in which image data is printed using the thermal transfer device according to the present invention.

이를 참조하면, 플래튼 롤러의 작용에 의하여 급지카세트로부터 리본카트리지의 하부로 이송된 용지(90)는 R, G, B의 각 단일의 칼라 화소만이 코팅된 형태의 독립된 3개의 열전사리본(80)과 밀착된 상태에서 각각의 TPH(40)를 통과하게 된다.Referring to this, the paper 90 transferred from the paper feed cassette to the lower part of the ribbon cartridge by the action of the platen roller is divided into three independent thermal transfer ribbons in which only a single color pixel of R, G, and B is coated. 80 and pass through each TPH (40) in close contact.

이와 같은 프린팅작업시 용지(90)가 각 TPH(40)를 통과하는 과정에서는 각각의 공급릴(60)(60')(60'')에 감겨진 단일 칼라화소만이 코팅된 각 열전사리본(80)이 권취릴(70)(70')(70'')로 이송되면서 상기한 TPH(40)의 발열량에 따라 대응되는 각 칼라의 화소가 용지(90)의 표면에 전사되므로써 삼원색의 배합에 의해 R, G, B칼라에 대응되는 화상 데이터가 동시에 인쇄되는 것이다.In the printing process, when the paper 90 passes through each TPH 40, each thermal transfer ribbon is coated with only a single color pixel wound around each feed reel 60, 60 ', 60' '. 80 is conveyed to the winding reels 70, 70 'and 70 ", so that the pixels of each color corresponding to the calorific value of the TPH 40 are transferred to the surface of the paper 90 so that the three primary colors are combined. By this, image data corresponding to R, G, and B colors are simultaneously printed.

이와 같은 본 발명을 적용하면, 삼원색을 이루는 R, G, B의 각 단일의 칼라 화소만이 코팅된 형태의 독립된 3개의 열전사리본이 단일의 수납케이스 내부에서 각각 독립된 공급릴과 권취릴상에 감져지도록 구성되고, 상기 각 열전사리본에는 독립된 TPH가 작용함에 따라 용지가 TPH를 1회 통과하는 과정에서 R,G,B 칼라에 대응되는 화상 데이터가 동시에 인쇄되어 출력시간이 현저히 단축된다.According to the present invention, three independent thermal transfer ribbons in which only a single color pixel of R, G, and B forming three primary colors are coated are wound on separate supply and winding reels in a single storage case. It is configured to be cut, and as the independent TPH acts on each of the thermal transfer ribbons, image data corresponding to R, G, and B colors are simultaneously printed in the process of passing the paper once.

또한, 3회 왕복에 필요한 기구적인 구성이 배제됨에 따라 내부구조가 단순해진다는 효과가 있다.In addition, since the mechanical configuration required for three round trips is eliminated, the internal structure is simplified.
