Description

레이저 빔 프린터에 있어서 이중정착 방법 및 장치Dual fixation method and apparatus in laser beam printer

본 발명은 레이저 빔 프린터의 정착기에 관한 것으로, 특히 충분한 정착온도와압력이 용지에 가해 지도록 이중정착기를 사용하여 레이저프린터와 같은 전자사진 인쇄장치의 정착품질을 개선하기 위한 이중 정착기를 가지는 레이저 빔 프린터의 이중정착방법 및 장치에 관한것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device of a laser beam printer, and more particularly to a laser beam printer having a double fixing device for improving the fixing quality of an electrophotographic printing apparatus such as a laser printer by using a double fixing device such that sufficient fixing temperature and pressure are applied to the paper. The double fixing method and apparatus of the present invention.

제1도에서와 같이 종래의 전자사진 현상방식의 레이저 프린터와 같은 출력장치는 최종단에서 종이에 전사된 토너를 열과 압력에 의해 정착되도록 하는 히터롤러(1)와 백업롤러(3)로 구성되어 있다. 그런데 상기 정착기(100)를 거치면서 토너는 종이에 융착되어 인쇄된 내용이 지워지지 않는 정착성을 가지게 된다. 그러나 상기의 종래의 정착기(1)는 일반적으로 사용하는 소형기기나 저속 출력기기에서는 문제가 되지 안으나 고속 출력기기를 만드는 경우에는 정착품질을 유지하는데 다음과 같은 문제가 있다. 상기 정착품질은 온도와 압력과 종이가 정착롤러 사이에 있는 시간과 밀접한 관계를 가지므로 고속 출력기기인 경우 종이의 속도가 빠른 관계로 종이가 정착기 롤러내에 머무는 시간이 짧아서 필요한 정착온도와 압력이 충분히 종이에 가해지지 못한 상태에서 종이가 바로 출력되어 정착품질을 떨어 뜨리게 된다. 종래에는 이를 해결하기 위해 종이의 속도가 올라감에 따라 정착기의 온도를 상대적으로 올리거나 롤러의 크기를 크게 하거나 하는 방법을 강구 하였으나 오히려 종이가 열을 너무 많이 받아 만지기 어렵거나 롤러가 너무커서 구성에 근본적인 문제점이 있다.As shown in FIG. 1, a conventional output device such as an electrophotographic laser printer is composed of a heater roller 1 and a backup roller 3 for fixing the toner transferred to paper at the final stage by heat and pressure. have. By the way, while passing through the fixing unit 100, the toner is fused to paper and has a fixing property in which the printed contents are not erased. However, the conventional fuser 1 is not a problem in a small apparatus or a low speed output device that is generally used, but when making a high speed output device, there are the following problems in maintaining the fixing quality. Since the fixing quality has a close relationship with temperature and pressure and the time between the paper and the fixing roller, the paper has a high speed in the case of a high speed output device, so that the paper has a short time to stay in the fixing roller, so that the necessary fixing temperature and pressure are sufficient. The paper is output immediately without being applied to the paper, and the fixing quality is lowered. Conventionally, in order to solve this problem, a method of increasing the temperature of the fixing unit or increasing the size of the roller as the paper speed increases has been devised, but rather, the paper is too hard to touch and the roller is too large. There is a problem.

따라서 본 발명의 목적은 고속기가 될 수록 충분한 온도와 압력이 종이에 가해지지 못하고 있는 부분을 개선코자 2개혹은 3개의 복수의 정착기를 가지는 구조로 변경하여 정착되어야 하는 종이에 충분한 압력과 온도를 가할수 있는 방법 및 장치를 제공함에 있다.Therefore, an object of the present invention is to change the portion of the high speed machine is not enough temperature and pressure applied to the paper in order to improve the structure to have two or three plural fusing unit to apply sufficient pressure and temperature to the paper to be fixed To provide a method and apparatus that can be.

도 2는 본발명의 실시예에 따른 이중정착기를 가진 레이저 빔프린터를 가진 시스템도2 is a system diagram with a laser beam printer having a double fixing device according to an embodiment of the present invention.

이하 본 발명을 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 실시예에 따른 이중정착기를 가진 레이저 빔 프린터의 시스템도로서,2 is a system diagram of a laser beam printer with a double fixing device according to an embodiment of the present invention,

본 발명은 종래의 정착기(100)와 같이 히트롤러(1)와 백업롤러(3)로 구성된 정착기를 복수의 이중으로 제1,2정착기(200,202)로 연결시켜서 종이가 그 사이를 지나면서 2회이상의 복수로 정착될수 있어 충분한 압력과 온도를 가하도록 구성 되어있다.The present invention connects a fuser composed of a heat roller (1) and a backup roller (3) to a plurality of double first and second fixing units (200, 202) like a conventional fuser 100, so that the paper passes between them two or more times. It can be settled in plurality, so it is configured to apply sufficient pressure and temperature.

상기 제1,2정착기(200,202)의 적어도 하나의 정착기 내부는 종래와 같이 발렬램프(2),히터롤러(1),압축롤러(3)의 구성은 동일하며, 이와 같은 구성을 복수로 2개이상을 설치하여 감광롤러(10)와 전사롤러(5)를 거친 용지는 제1정착기(200)를 지나 제2정착기(202)를 거쳐 출력되므로 같은 온도와 압력으로 2회 이상 반복되어 출력되므로 정착품질을 향상시킬수있게 된다. 즉 본 발명의 예는 제1,2정착기(200,201)를 가지므로써 종래에 구조적으로 가지는 히터롤러(1)의 치수가 커야 되는 문제를 제1,2정착기(200,201)를 사용하여 해결할 수 있으며, 통상 고속출력시 히터롤러의 온도를 보상하기 위해 치수를 크게하여야 되나 이를위해 정착기를 이중으로 사용하여 작은 롤러로 출력장치에 부착하여 치수상에 제한 요소를 배제할수 있으므로 제품외관과 디자인에 유연성을 가질수 있다.At least one fixing unit of the first and second fixing units 200 and 202 has the same configuration as that of the heat generating lamp 2, the heater roller 1, and the compression roller 3 as in the related art. Since the paper having passed through the photosensitive roller 10 and the transfer roller 5 is output through the first fixing device 200 and the second fixing device 202, the paper is repeatedly outputted two times or more at the same temperature and pressure. It can improve the quality. That is, the example of the present invention can solve the problem that the dimensions of the heater roller (1) having a conventional structure having a large by having the first, second fixing device (200, 201), using the first, second fixing device (200, 201), usually In order to compensate for the temperature of the heater roller at high speed output, the size should be increased, but for this purpose, it is possible to have flexibility in product appearance and design because the limiting element can be eliminated by attaching to the output device with a small roller by using the fixing unit twice. .

상술한 바와 같이 고속기가 될 수록 충분한 온도와 압력이 종이에 가해지지 못하고 있는 부분을 개선코자 2개혹은 3개의 정착기를 가지는 구조로 변경하여 정착되어야 하는 종이에 충분한 압력과 온도를 가할수 있도록 하되, 상대적으로 정착기의 히트롤러 온도를 종래에 그리고 경우에 따라 고속기인 경우 토너의 융착점을 낮추어야 하는 문제로 개선될수 있는 이점이 있다.As described above, the higher the speed, the more the temperature and pressure is not applied to the paper to improve the structure to have two or three fixing units to improve the pressure and temperature to the paper to be fixed, There is an advantage that the heat roller temperature of the fixing unit can be improved by the problem of lowering the fusion point of the toner conventionally and in some cases, in the case of a high speed machine.
