Description
본 발명은 습식 전자사진방식 프린터의 현상액 공급장치에 관한 것이다.The present invention relates to a developing solution supply apparatus for a wet electrophotographic printer.
예컨대 칼라 레이저 프린터와 같은 습식 전자사진방식 프린터는, 도 1에 도시된 바와 같이, 감광매체인 감광벨트(10)에 레이저 빔을 주사하여 정전잠상(Latent electrosatic image)을 형성시키는 레이저 스캐너(60)와, 상기 감광벨트(10)에 분말상의 토너와 액상의 용매가 혼합된 현상액을 분사하여 상기 정전잠상을 소정 색상의 화상으로 현상하는 현상기(20)와, 현상 후 감광벨트(10)의 화상에 잔류하는 용매를 건조시키는 건조유닛(30)과, 건조된 화상을 용지(S)에 인쇄하는 전사유닛(40)을 구비하고 있다. 그리고 상기 현상기(20)에 현상작업을 위한 소정 농도의 현상액을 계속 공급하기 위한 현상액 공급장치(50)이 구비되어 있는데, 이 현상액 공급장치(50)는 약 9 wt% 정도의 고농도 농축 현상액이 저장되는 농축현상액저장탱크(52)와, 용매가 저장되는 용매저장탱크(53), 상기 농축현상액저장탱크(52)와 용매저장탱크(53)에서 각각 소정량의 액을 받아들여 실제 현상작업에 적합한 농도인 2∼4 wt% 정도의 현상액을 만드는 혼합탱크(51) 및, 상기 혼합탱크(51)에서 열화된 현상액을 드레인시켜 저장하는 폐현상액회수탱크(54)를 포함하고 있다. 참조부호 52a, 53a, 54a는 각각 밸브를 나타내는 것으로, 이 밸브들(52a, 53a, 54a)의 개폐동작에 의해 각 탱크들 사이에 액체 이동이 이루어진다. 그리고 참조부호 55는 상기 혼합탱크(51)에서 현상기(20)로 현상액을 펌핑하는 공급펌프를 나타내며, 참조부호 56은 혼합탱크(51) 내의 현상액 농도를 측정하기 위한 농도센서를 나타낸다.For example, a wet electrophotographic printer such as a color laser printer, as shown in FIG. 1, scans a laser beam on a photosensitive belt 10 that is a photosensitive medium to form a latent electrosatic image. And a developing unit 20 for spraying a developing solution containing a powdered toner and a liquid solvent onto the photosensitive belt 10 to develop the electrostatic latent image into an image of a predetermined color, and to the image of the photosensitive belt 10 after development. A drying unit 30 for drying the remaining solvent, and a transfer unit 40 for printing the dried image on the paper (S). In addition, the developer 20 is provided with a developer supply device 50 for continuously supplying a developer of a predetermined concentration for a developing operation. The developer supply device 50 stores a concentrated developer of about 9 wt%. Concentrated developer storage tank 52, the solvent storage tank 53, the solvent is stored, the concentrated developer storage tank 52 and the solvent storage tank 53, respectively receives a predetermined amount of liquid suitable for the actual development work. A mixing tank 51 for producing a developer having a concentration of about 2 to 4 wt% and a waste developing solution recovery tank 54 for draining and storing the developer deteriorated in the mixing tank 51 are included. Reference numerals 52a, 53a, and 54a denote valves, respectively, and liquid movement is performed between the tanks by opening and closing operations of the valves 52a, 53a, and 54a. Reference numeral 55 denotes a supply pump for pumping developer from the mixing tank 51 to the developer 20, and reference numeral 56 denotes a concentration sensor for measuring the developer concentration in the mixing tank 51.
그런데 상기 구성에 있어서 현상작업과 현상액 공급작업이 반복되다보면, 상기의 밸브들(52a)(53a)(54a) 또는 상기 각 탱크(51)(52)(53)를 연결하는 연결관(52b)(53b)(54b)의 접속부 등에서 현상액이나 용매가 누수될 가능성이 있다. 만일 이와 같이 밸브(52a)(53a)(54a)를 통해 연결관 내부로 현상액이나 용매가 계속 누수되게 되면 특히 상기 혼합탱크(51) 내에서 정확한 농도가 유지되지 않아 농도제어가 상당히 어려워지게 되며, 또한 연결관(52b)(53b)(54b) 외부를 따라 액이 새어나오게 되면 프린터 내부가 크게 오염될 수 있고, 각종 회로물이 새어나온 액체에 의해 오염되어 정상기능을 상실할 위험이 있다.However, when the developing operation and the developer supply operation are repeated in the above configuration, the connecting pipe 52b connecting the valves 52a, 53a, 54a or the respective tanks 51, 52, 53. There is a possibility that the developer or the solvent leaks at the connection portion of (53b) and 54b. If the developer or the solvent continuously leaks into the connection pipe through the valves 52a, 53a, and 54a in this way, it becomes difficult to control the concentration because the accurate concentration is not maintained in the mixing tank 51, in particular. In addition, when the liquid leaks out along the outside of the connecting pipes 52b, 53b, 54b, the inside of the printer may be greatly contaminated, and various circuits may be contaminated by the leaked liquid, thereby losing the normal function.
따라서 현상액 또는 용매가 새어나올 경우를 대비한 대책이 요구되고 있다.Therefore, a countermeasure in case a developer or a solvent leaks is calculated | required.
본 발명은 상기의 점을 감안하여 창출된 것으로서, 현상액 이나 용매의 누수여부를 감지하여 사용자에게 알릴 수 있도록 구조 개선된 습식 전자사진방식 프린터의 현상액 공급장치를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and an object thereof is to provide a developer supplying apparatus of a wet electrophotographic printer having an improved structure to notify a user by detecting a leak of a developer or a solvent.

Thereafter, the supply pump 350 is driven and supplied to the developing unit 200 in which a developing operation is performed. On the other hand, when opening the valves 311 and 321 and supplying the concentrated developer and the solvent to the mixing tank 330, the opening / closing valves 314 and 324 provided at the bottom of the accommodation container 313 and 323 are also opened. By the connection pipes 312, 322 to allow the liquid to smoothly enter the mixing tank 330. After the developer to be supplied to the developer 200 is prepared, the valves 311 and 321 and the on-off valves 314 and 324 of the connection pipes 312 and 322 are closed. At this time, the space portions 313a and 323a of the accommodation containers 313 and 323 are empty and are supported in a horizontal state by the springs 315 and 325 and the hinge coupling portions 316 and 326. have.
그런데 만일 상기 연결관(312)(322)의 이음매 부분이나 상기 밸브(311)(321) 등에서 누수가 발생되어 상기 연결관(312)(322)의 내외부를 타고 액이 흘러나오게 되면, 그 흘러나온 액이 그 연결관(312)(322)을 따라 흘러내려서 상기 수용용기(313)(323)의 공간부(313a)(323a)로 떨어져 모이게 된다. 그리고 누수가 계속되어 수용용기(313)(323)에 모인 액이 많아지게 되면, 그 중량의 증가에 의해상기 스프링(315)(325)이 늘어나면서 수용용기(313)(323)가 기울어지게 된다. 이에 따라 상기 센서플레이트(317)(327)도 함께 변위하게 되어 이를 센서(318)(328)가 감지하게 된다. 따라서 이 센서(318)(328)에 의한 감지신호를 전송받아 모니터등에 에러 메시지로 디스플레이시키면, 누수사실을 사용자가 쉽게 알 수 있게 된다.However, if water leaks from the joints of the connection pipes 312 and 322 or the valves 311 and 321 and the liquid flows out inside and outside of the connection pipes 312 and 322, the liquid flows out. The liquid flows down the connecting pipes 312 and 322 to fall into the spaces 313a and 323a of the receiving containers 313 and 323. If the leakage continues to increase the amount of liquid collected in the container 313, 323, the spring 315, 325 is increased by the increase of the weight, the container 313, 323 is inclined. . Accordingly, the sensor plates 317 and 327 are also displaced together so that the sensors 318 and 328 sense this. Therefore, when the detection signal by the sensor 318 (328) is received and displayed as an error message on the monitor, the user can easily see the leak.
마찬가지로 상기 폐현상액회수탱크(340)에 설치된 누수감지수단도 동일한 방식으로 누수여부를 감지하여 사용자에게 알리게 된다.Similarly, the leak detection means installed in the waste developing solution recovery tank 340 detects the leak in the same manner and informs the user.
따라서 상기 누수감지수단으로 각 연결관(312)(322)(342) 주변에서 발생되는 누수여부를 감지하여 사용자가 알 수 있도록 함으로써, 누수가 발생되더라도 빠른 시간내에 조취를 취할 수 있게 되어 현상액 농도 조절의 오류를 방지하고 프린터 내부의 오염을 억제할 수 있게 된다.Therefore, by detecting the leakage occurring around each of the connection pipes (312, 322, 342) by the leak detection means so that the user can know, it is possible to take a quick action even if a leak occurs, the developer concentration control This can prevent errors and suppress contamination inside the printer.
상술한 바와 같이 본 발명에 따른 습식 전자사진방식 프린터의 현상액 공급장치는, 각 탱크들의 연결관 주변에서 누수가 발생되더라도 이를 신속하게 사용자에게 알릴 수 있으므로 현상액 농도 조절의 신뢰도를 높일 수 있고, 프린터 내부의 오염을 억제하여 내부기기를 보호할 수 있는 이점을 가진다.As described above, the developer supply apparatus of the wet electrophotographic printer according to the present invention can quickly notify the user even if a leak occurs around the connection pipe of each tank, thereby increasing the reliability of the developer concentration control and increasing the inside of the printer. It has the advantage of protecting internal equipment by suppressing contamination.
본 발명은 상기에 설명되고 도면에 예시된 것에 의해 한정되는 것은 아니며 다음에 기재되는 청구의 범위 내에서 더 많은 변형 및 변용예가 가능한 것임은 물론이다.It is to be understood that the invention is not limited to that described above and illustrated in the drawings and that many more modifications and variations are possible within the scope of the following claims.
