화상형성장치용 토너카트리지{Toner cartridge for a image forming apparatus}Toner cartridge for an image forming apparatus

본 발명은 레이저 프린터 등에 적용되는 화상형성장치에 관한 것으로서, 특히 상기 화상형성장치에 소정의 색상을 가진 토너를 보급하는 화상형성장치용 토너카트리지에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus applied to a laser printer and the like, and more particularly, to a toner cartridge for an image forming apparatus for supplying a toner having a predetermined color to the image forming apparatus.

일반적으로 레이저 프린터 등에 적용되는 화상형성장치는 감광드럼 또는 감광벨트와 같은 감광매체에 정전잠상(Latent electrostatic image)을 형성시키고 소정의 색상을 가진 토너로 상기 정전잠상을 현상한 뒤 기록지에 전사시켜 원하는 화상을 얻는 장치이다. 레이저 프린터는 사용하는 토너에 따라 습식과 건식으로 크게 대별되는데, 습식 레이저 프린터에는 휘발 성분의 액상의 케리어에 토너가 섞여 있는 현상액이 사용된다. 이러한 현상액을 이용하는 습식 레이저 프린터는 분말 상태의 토너를 이용하는 건식 레이저 프린터보다 인쇄 품질이 좋으며, 유해한 토너 분진에 의한 피해를 방지할 수 있어 그 이용이 점차 증가하는 추세이다.In general, an image forming apparatus applied to a laser printer or the like forms a latent electrostatic image on a photosensitive medium such as a photosensitive drum or a photosensitive belt, develops the electrostatic latent image with a toner having a predetermined color, and transfers the image onto a recording sheet. It is a device that obtains an image. Laser printers are roughly classified into wet and dry, depending on the toner used. In a wet laser printer, a developer in which a toner is mixed in a liquid carrier of a volatile component is used. The wet laser printer using the developer has better print quality than the dry laser printer using the powder toner, and can prevent damage caused by harmful toner dust, and its use is gradually increasing.

도 1은 종래의 화상형성장치의 주요부 구조를 나타낸 개략적 구성도이다.1 is a schematic block diagram showing the structure of a main part of a conventional image forming apparatus.

도시된 바와 같이, 종래의 일반적인 습식 칼라 레이저 프린터는 무한궤도의 감광벨트(110)와, 이 감광벨트(110)를 주어진 경로에서 회전 이동시키는 1차 롤러(121), 2차 롤러(122) 및 3차 롤러(123)의 세 개의 롤러를 구비하고 있다.As shown in the drawing, a conventional general wet color laser printer includes an endless photosensitive belt 110, a primary roller 121, a secondary roller 122, which rotates the photosensitive belt 110 in a given path, and Three rollers of the tertiary roller 123 are provided.

그리고, 상기 감광벨트(110)의 일측부에 인접하여 감광벨트(110)를 균일하게 대전시키는 주대전기(135)가 마련되고, 감광벨트(110)의 하부에는 화상신호에 따라 감광벨트(110)에 레이저 빔을 조사하여 정전잠상을 형성시키는 LSU(Laser scanning unit, 130)와, 상기 정전잠상이 형성된 영역에 소정의 색상을 가진 토너와 액상의 케리어로 된 현상액을 부착시켜 현상하는 현상장치(140)가 설치되어 있다. 칼라 프린트인 경우에는 색상의 조합을 위해 다수개의 LSU(130)와 다수의 색상을 가진 현상액을 각각 분리하여 담고 있는 다수개의 현상장치(140)가 구비된다.In addition, a main charging unit 135 for uniformly charging the photosensitive belt 110 is provided adjacent to one side of the photosensitive belt 110, and the photosensitive belt 110 is disposed below the photosensitive belt 110 according to an image signal. A developing device 140 for attaching and developing a laser scanning unit (LSU) 130 for irradiating a laser beam to form an electrostatic latent image, and attaching a toner having a predetermined color and a developer made of a liquid carrier to an area where the electrostatic latent image is formed. ) Is installed. In the case of color printing, a plurality of developing devices 140 are provided to separately contain a plurality of LSUs 130 and a developer having a plurality of colors for color combinations.

좀더 상세히 설명하면, 습식 칼라 레이저 프린터에는 일반적으로 네 개의 LSU(130a,130b,130c,130d)와 네 개의 현상장치(140a,140b,140c,140d)가 설치된다. 상기 네 개의 현상장치(140a~140d)는 각각 Y(Yellow), M(Magenta), C(Cyan), K(Black)로 표시되는 색상의 토너를 상기 감광벨트(110)에 부착시키게 된다. 그리고, 상기 네 개의 LSU(130a~130d)도 각각 상기 네 개의 현상장치(140a~140d) 직전에 설치된다. 따라서, 첫 번째 LSU(130a)에 의해 감광벨트(110)에는 Y(Yellow, 노란색) 색상에 해당되는 정전잠상이 형성되고, 첫 번째 현상장치(140a)에서 Y로 표시되는 색상을 가진 토너를 상기 정전잠상이 형성된 영역에 부착시키게 된다. 이와 같이 상기 네가지의 색상을 가진 토너를 상기 감광벨트에 차례대로 부착시킴으로써 원하는 칼라색상을 얻게 된다.In more detail, a wet color laser printer is generally provided with four LSUs 130a, 130b, 130c and 130d and four developing devices 140a, 140b, 140c and 140d. The four developing devices 140a to 140d attach toners of the color indicated by Y (Yellow), M (Magenta), C (Cyan), and K (Black) to the photosensitive belt 110, respectively. The four LSUs 130a to 130d are also provided immediately before the four developing devices 140a to 140d, respectively. Accordingly, an electrostatic latent image corresponding to Y (Yellow, Yellow) color is formed on the photosensitive belt 110 by the first LSU 130a, and the toner having a color indicated by Y in the first developing device 140a is recalled. It is attached to the area where the electrostatic latent image is formed. Thus, by attaching the toner having the four colors to the photosensitive belt in turn, a desired color color is obtained.

그리고, 상기 네 개의 현상장치(140a~140d)에 네가지의 색상을 가진 토너를 각각 보급하기 위한 토너카트리지(160)가 마련되어 있다. 상기 토너카트리지(160)는 Y, M, C, K로 표시되는 색상을 가진 토너를 담고 있는 네 개의 토너통(161a,161b,161c,161d)과, 상기 네 개의 토너통(161a~161d)이 각각 장착되어 지지되는 네 개의 토너호퍼(162a,162b,162c,162d)로 구성된다.The four developing devices 140a to 140d are provided with toner cartridges 160 for supplying toners having four colors. The toner cartridge 160 includes four toner containers 161a, 161b, 161c, and 161d containing toners having colors represented by Y, M, C, and K, and the four toner containers 161a to 161d. Four toner hoppers 162a, 162b, 162c, and 162d are mounted and supported, respectively.

상술한 바와 같이 상기 현상장치(140)에 의해 감광벨트(110)에 부착된 현상액은 현상장치(140) 이후에 마련된 건조롤러(151)와 히트롤러(152)에 의해 건조되어 액상의 케리어가 제거되므로 감광벨트(110)의 정전잠상에는 토너만 남은 토너상이 형성된다.As described above, the developer attached to the photosensitive belt 110 by the developing device 140 is dried by the drying roller 151 and the heat roller 152 provided after the developing device 140 to remove the liquid carrier. Therefore, the toner image remaining only toner is formed in the latent electrostatic image of the photosensitive belt 110.

상기 토너상은 감광벨트(110)를 사이에 두고 상기 1차 롤러(121)와 평행하게 설치된 전사롤러(124)에 의해 기록지(126)에 전사된다. 상기 기록지(126)는 상기 전사롤러(124)와 소정의 간격을 두고 그와 평행하게 설치된 가압롤러(125)의 사이를 통해 공급되고, 상술한 바와 같이 기록지(126)에 전사된 토너상은 별도의 정착장치(미도시)에 의해 정착되어 최종적으로 원하는 화상을 얻게 된다.The toner image is transferred to the recording paper 126 by a transfer roller 124 provided in parallel with the primary roller 121 with the photosensitive belt 110 interposed therebetween. The recording paper 126 is supplied between the transfer roller 124 and the pressure roller 125 installed in parallel with a predetermined interval therebetween, and the toner image transferred to the recording paper 126 is separated as described above. It is fixed by a fixing device (not shown) to finally obtain a desired image.

그런데 상술한 바와 같이 구성되어 작동되는 습식 칼라 레이저 프린터에 설치되는 토너카트리지(160)에는 다음과 같은 문제점이 있다. 상기 토너통(161) 내부의 토너가 소모되면 토너통(161)을 교체하여야 하는데, 이 과정에서 토너통(161)의 위치가 바뀌어 장착됨으로써 기록지(126)에 전사되는 화상의 색상이 바뀌는 현상불량을 발생시키는 경우가 있다. 즉, 각각의 색상을 가진 토너가 담긴 네 개의 토너통(161a~161d)의 외관형상이 모두 같아서 사용자의 실수로 제 위치의 토너호퍼(162a~162d)에 장착되지 못하고 다른 위치에 장착될 수 있는 문제점이 있다. 이와 같은 문제점을 해결하기 위해 각 토너통(161a~161d)과 각 토너호퍼(162a~162d)에 칼라라벨을 부착하여 식별하는 수단이 사용되고 있다. 그러나, 상기 칼라라벨이 떨어지거나, 장기 사용으로 칼라라벨의 색상이 흐려지거나, 사용자가 미처 확인하지 못한 경우 등에는 상술한 바와 같은 문제점이 발생하게 된다.However, the toner cartridge 160 installed in the wet color laser printer constructed and operated as described above has the following problems. When the toner inside the toner container 161 is used up, the toner container 161 needs to be replaced. In this process, the position of the toner container 161 is changed so that the color of the image transferred to the recording paper 126 is changed. May be generated. That is, the appearance of the four toner containers 161a to 161d containing the toners of each color are all the same, so that the toner hoppers 162a to 162d may not be mounted on the toner hoppers 162a to 162d by mistake. There is a problem. In order to solve such a problem, a means of identifying and attaching color labels to each of the toner containers 161a to 161d and the toner hoppers 162a to 162d is used. However, when the color label is dropped, the color of the color label is blurred due to long-term use, or the user fails to check it, the above-described problems occur.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로, 각 색상별로 토너통을 식별하는 수단이 개선된 화상형성장치용 토너카트리지를 제공하는데 목적이 있다.The present invention has been made to solve the above problems of the prior art, and an object of the present invention is to provide a toner cartridge for an image forming apparatus in which a means for identifying a toner container for each color is improved.

That is, the four toner hoppers 262a to 262d and the four toner containers 261a to 261d have a difference in shape at their coupling portions. For example, the shape of the engaging portion of the toner container 261a containing the toner having the color indicated by the Y and the toner hopper 262a coupled thereto is different from that of the toner containers 261b, 261c and 261d having different colors. .

구체적으로 설명하면, 상기 네 개의 토너통(261a~261d)의 하면에는 리브(263a,263b,263c,263d)가 돌출형성되는데, 각 토너통(261a~261d)에 담긴 토너의 색상별로 그 위치를 달리 한다. 그리고, 상기 토너통(261a~261d)이 장착되는 토너호퍼(262a~262d)에는 상기 리브(263a~263d)와 대응하는 위치에 상기 리브(263a~263d)가 끼워지는 홈(264a,264b,264c,264d)이 형성된다. 따라서, 토너통(261a~261d)은 제 위치의 토너호퍼(262a~262d)에만 장착가능하게 된다.Specifically, ribs 263a, 263b, 263c, and 263d are protruded from the lower surfaces of the four toner bottles 261a to 261d. The positions of the toners included in the toner bottles 261a to 261d are determined by the color of the toner. Do it differently. In addition, grooves 264a, 264b, and 264c into which the ribs 263a to 263d are fitted in positions corresponding to the ribs 263a to 263d in the toner hoppers 262a to 262d to which the toner containers 261a to 261d are mounted. 264d) is formed. Therefore, the toner containers 261a to 261d can be mounted only on the toner hoppers 262a to 262d in position.

예컨데, Y(Yellow, 노란색) 색상을 가진 토너가 담긴 토너통(261a)을 제 위치의 토너호퍼(262a)에 장착할 때에는, 상기 토너통(261a)에 형성된 리브(263a)와 상기 토너호퍼(262a)에 형성된 홈(264a)의 위치가 일치하여 상기 토너통(261a)의 장착이 가능하게 된다. 반면에 상기 토너통(261a)을 제 위치가 아닌 토너호퍼(262b,262c,262d)에 장착할 때에는, 상기 리브(263a)와 제 위치가 아닌 토너호퍼(262b,262c,262d)에 형성된 홈(264b,264c,264d)의 위치가 다르므로 장착이 불가능하게 된다.For example, when the toner container 261a containing the toner of Y (Yellow, Yellow) color is mounted in the toner hopper 262a in place, the rib 263a and the toner hopper (26) formed in the toner container 261a are mounted. The positions of the grooves 264a formed in the 262a coincide, so that the toner container 261a can be mounted. On the other hand, when the toner container 261a is mounted in the toner hoppers 262b, 262c, and 262d, which are not in position, the grooves formed in the ribs 263a and the toner hoppers 262b, 262c, and 262d, which are not in position, 264b, 264c, and 264d are different from each other, so mounting is impossible.

이와 같이 본 발명에 따른 화상형성장치용 토너카트리지(260)는 토너통(261a~261d)의 식별수단이 종래 사용자의 육안에 의존하던 방식과는 달리 토너통(261a~261d)과 토너호퍼(262a~262d)가 상보적 결합을 하게 되므로, 토너통(261a~261d)이 바뀌어 장착될 때에는 장착 자체가 불가능하게 되어 사용자의 실수에 의해 토너통(261a~261d)이 바뀌어 장착됨으로써 발생되는 현상불량을 근본적으로 방지할 수 있게 된다.As described above, the toner cartridge 260 for an image forming apparatus according to the present invention is different from the way in which the identification means of the toner containers 261a to 261d depends on the naked eye of the conventional user, and the toner containers 261a to 261d and the toner hopper 262a. 262d) are complementary to each other, and when the toner containers 261a to 261d are replaced and mounted, the mounting itself is impossible, and the toner bottles 261a to 261d are changed by the user's mistake, resulting in defective development. Fundamentally preventable.
