본 고안은 복사기에서 토너를 열정착시키는 가열롤러의 온도를 감지할 수 있도록 하는 복사기용 온도감지기에 관한 것으로, 특히, 온도감지기(Thermistor)로 가열롤러의 온도를 감지할 때 온도감지기가 차지하는 공간을 최소화하고, 온도감지센서에 의한 가열롤러의 손상을 방지함과 동시에 온도감지기의 제작을 용이하게 하여 생산성을 향상시킬 수 있도록 하는 복사기용 온도감지기에 관한 것이다.The present invention relates to a temperature sensor for a copier, which enables the copier to sense the temperature of the heating roller that adheres the toner passionately. In particular, the temperature sensor occupies the space occupied by the temperature sensor when the temperature of the heating roller is sensed by a temperature detector. The present invention relates to a temperature sensor for a copier which minimizes and prevents damage to a heating roller by a temperature sensor and at the same time facilitates the production of a temperature sensor to improve productivity.

일반적으로 복사기의 토너정착은 회전하는 두 개의 롤러 사이로 종이를 통과시켜 종이에 뿌려진 토너가 열에 의해 종이에 정착되도록 하는 방식이 사용되고 있으며, 복사물의 기록농도와 분포의 일괄성, 선명함 등의 기록품질은 복사기 각 기구의 정도에 좌우됨은 물론 정착용 가열롤러의 온도 역시 기록품질을 결정하는 중요한 요소로 인식되어 있으므로 그 가열롤러의 온도를 최적의 상태로 제어하기 위하여 온도감지센서가 사용되고 있다.In general, the toner is fixed in the copier by passing the paper between two rotating rollers so that the toner sprayed on the paper is fixed to the paper by heat. Since the temperature of the fixing roller is also recognized as an important factor in determining the recording quality, the temperature sensor is used to control the temperature of the heating roller in an optimal state.

그러나, 종래의 복사기에 사용되어 온 온도감지기는 홀더에서 인출된 판스프링(51)의 상하측에 내마모성의 폴리미드(polymode)계 절연테이프(54)(55)를 구비하고, 상측의 절연테이프(54) 위에 온도감지센서(53)가 올려지는 실리콘스폰지(52)를 안착시킨 후, 절연테이프(54)(55)들을 실리콘스폰지(52)와 온도감지센서(53)의 외측으로 감착시킴으로서 가열롤러의 온도를 감지할 때 실리콘스폰지(52)의 쿠션작용과 판스프링(51)의 텐션작용으로 온도감지기와 가열롤러의 손상을 방지토록 하고 있으나, 이러한 온도감지기는 판스프링(51)위에 실리콘스폰지(52)를 구비함으로서 많은 설치면적을 필요로하게 될 뿐만 아니라, 판스프링(51) 상하측의 절연테이프(54)(55)를 온도감지센서(53)가 올려진 실리콘스폰지(52) 외측으로 감착시켜야 하는 것이므로 작업성과 생산성이 저하되는 문제점이 있었다.However, the temperature sensor used in the conventional copier includes a wear resistant polymode insulating tape 54 and 55 on the upper and lower sides of the leaf spring 51 drawn out from the holder, and the upper insulating tape ( 54. After placing the silicone sponge 52 on which the temperature sensor 53 is placed, the insulating tapes 54 and 55 are attached to the outside of the silicone sponge 52 and the temperature sensor 53 by heating rollers. When sensing the temperature of the silicone sponge 52, the cushioning action and the tension action of the leaf spring 51 to prevent damage to the temperature sensor and the heating roller, but the temperature sensor is a silicone sponge (on the leaf spring 51) In addition to the need for a large mounting area, the insulating tapes 54 and 55 on the upper and lower side of the leaf springs 51 are attached to the outside of the silicone sponge 52 on which the temperature sensor 53 is mounted.
