Abstract

본 발명은 전자사진 현상기기의 정착부의 로울러를 완전히 분리한 상태로 설치한 상태에서 로울러의 형합이 안정되게 이루어지도록 하는 정착장치에 관한 것으로, 종래에는 열을 제공하는 가열로울러와 밀착력을 제공하는 압착로울러를 면접촉시키기 위하여 사진현상기기의 제작공정에서 각 프레임에 정착부의 로울러들을 밀착될 수 있는 규격으로 고정식 또는 개폐식으로 설치하였으므로 용지가 정착부에 걸린 경우에 고정식의 경우 기기의 본체를 열어도 정착기를 분해하지 않고는 면접촉된 로울러를 분리할 수 없고 개폐식의 정착부의 경우 에는 본체가 일측을 지점으로 하여 벌어질때 가열로울러와 압력로울러의 면접촉상태가 소정의 각도로 벌어지게 되나 개방된 공간내에서 로울러지지용 프레임이 벌어지는 것이어서 개폐각도에 대한 제한과, 벌어진 각도범위에서 할 수 있는 작업도 제한적인 문제점이 있었다. 본 발명은 정착부의 가열 및 압착로울러(6,7)가 각각 상하부본체(2A,2B)에 별도로 설치되어 본체(1)의 분리시에는 각 로울러가 본체(1)의 분리동작에 의하여 개방되는 것이어서 공간에 대한 제한을 받지 않으며 본체의 결합시에는 각 로울러가 압력조정볼트(11)와 압력 스프링(9)에 의하여 소정의 압력으로 면접촉을 이루게 하는 것으로 일반 복사기, 레이져 프린터, 팩시밀리등에 적용된다.The present invention relates to a fixing apparatus for stably matching the rollers in a state in which the rollers of the fixing unit of the electrophotographic developing apparatus are completely separated from each other. In order to make contact with the rollers, in the manufacturing process of the photodeveloper, a fixed or open type is installed in the frame so that the rollers of the fixing unit may be in close contact with each frame. It is impossible to separate the surface contacted rollers without disassembling. In the case of an open-type fixing unit, when the main body is opened with one side, the surface contact state of the heating roller and the pressure roller is opened at a predetermined angle. In the roller support frame is opened in the limit of the opening and closing angle, There was also a limited problem that can be done in the open angle range. According to the present invention, the heating and pressing rollers 6 and 7 of the fixing unit are separately installed on the upper and lower body 2A and 2B, respectively, and the rollers are opened by the separating operation of the main body 1 when the main body 1 is separated. It is not limited to the space, and when the main body is combined, the rollers make surface contact at a predetermined pressure by the pressure adjusting bolt 11 and the pressure spring 9, and are applied to general copiers, laser printers, fax machines, and the like.
