본 고안은 전자 사진 방식을 이용한 프로세서의 급지용 카세트에 관한 것으로서 보다 개량된 용지가압장치를 카세트 내부에 내설하여 카세트에 용지를 안정되게 적재하기 위한 장치에 관한 것이다.The present invention relates to a cassette for feeding a processor using an electrophotographic method, and more particularly, to an apparatus for stably loading a paper into a cassette by incorporating an improved paper pressing device into a cassette.

종래에 사용되었던 급지용 카세트는 제1도에 도시된 바와 같이 용지(25)의 증송을 방지하기 위한 분리조(21)가 카세트(20)의 선단 양측모서리에 설치하고 밑면에는 압축 코일 스프링(22)으로 탄지되며 힌지측(23)에 의해 회동 가능한 용지받침판(24)으로 구성되었다.In the conventional cassette for feeding, as shown in FIG. 1, a separation tank 21 is installed at both ends of the front end of the cassette 20 to prevent the paper 25 from being transferred. It was composed of a paper support plate 24 which is supported by the hinge side 23 and is rotatable by the hinge side 23.

이와 같이 구성된 급지용 카세트(20)에 용지(25) 적재시 용지받침판(24)를 사용자가 누른 상태에서 원하는 양만큼 용지(25)를 적재하면 용지(25)는 용지 받침판(24)의 밑면을 탄지하고 있는 압축코일 스프링(22)의 탄성에 의해 용지 받침판(24)이 힌지축(23)를 중심으로 상향으로 회동됨으로써 카세트(20) 상측에 위치한 급지로울러(26)에 가압된 상태가 된다.When the paper 25 is loaded in the paper cassette 20 configured as described above, and the user loads the paper support plate 24 in the desired amount while pressing the paper support plate 24, the paper 25 forms the bottom surface of the paper support plate 24. Due to the elasticity of the compressed coil spring 22 which is held, the paper support plate 24 is rotated upward with respect to the hinge axis 23, thereby being pressed against the paper feed roller 26 located above the cassette 20.

상기와 같은 상태에서 용지(25)가 적재된 급지용 카세트(20)를 기기의 급지부에 장착시키게 된다.In the above state, the paper feeding cassette 20 on which the paper 25 is loaded is mounted on the paper feeding portion of the machine.

상기와 같이 용지(25)가 적재된 급지용 카세트(20)를 장착시키면, 급지용 카세트(20)에 적재된 용지(25)중 최상면에 위치한 용지(25)가 급지로울러(26)에 급지되어진다.When the paper feed cassette 20 in which the paper 25 is loaded is mounted as described above, the paper 25 positioned on the top surface of the paper 25 loaded in the paper feed cassette 20 is fed to the paper feed roller 26. Lose.

상기와 같은 종래기술은 스프링이 용지받침판을 향상 상향으로 지지함으로써 용지 적재시 번거러움을 초래함과 동시에 다량의 용지적재가 어려웠으며 용지가 적재된 급지용 카세트를 기기의 급지부에 급지시 최상단에 위치한 용지가 급지로울러와의 마찰을 받아 용지가 후단으로 밀려나거나 꾸겨지는 문제가 발생하였다.In the prior art as described above, the spring supports the paper support plate upwards, which causes inconvenience in loading the paper and at the same time it is difficult to load a large amount of paper. There is a problem that the paper is pushed to the rear end or decorated due to friction with the paper feed roller.

본 고안은 상기와 같은 문제점을 해소하기 위하여 안출한 것으로서 급지용 카세트에 개량된 가압장치를 설치하여 용지를 손쉽게 적재함은 물론 다량의 용지를 적재할 수 있도록 하는데 본 고안의 목적이 있다.The present invention has been made in order to solve the above problems, it is an object of the present invention to install a pressurized improved device in the paper feed cassette to easily load the paper as well as to load a large amount of paper.

상기와 같은 목적을 달성하기 위한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment for achieving the above object will be described in detail with reference to the accompanying drawings.

카세트(1)선단 양모서리에 분리조와 내부에 힌지축(3)에 의해 회동가능한 용지 받침판(4)을 구비하는 급지용 카세트(1)에 있어서 카세트 양측벽(5)에는 하단에 록킹부(12)를 구비한 가이드홀(6)을 형성하고 가이드홀(6)에는 가압 로울로(7)를 구비한 샤프트(8)의 양단이 삽입 설치되며 상기 샤프트(8)는 토션스프링(9)으로 탄지하되 토션스프링(9)은 힌지(10)에 설치되어 일단이 돌출핀(11)에 탄지되고, 타측단은 샤프트(8)를 지지토록 하였다.In the cassette (1) for feeding having a paper support plate (4) rotatable by a separating tank and a hinge shaft (3) therein at both edges of the cassette (1), the cassette side (5) has a locking portion (12) at its lower end. The guide hole (6) is formed, and both ends of the shaft (8) having the pressure roller (7) are inserted into the guide hole (6), and the shaft (8) is supported by the torsion spring (9). However, the torsion spring 9 is installed on the hinge 10, one end of which is supported by the protruding pin 11, the other end to support the shaft (8).

상기와 같이 구성된 본 고안의 작용효과를 살펴보면 다음과 같다.Looking at the effect of the present invention configured as described above are as follows.

용지 가압장치가 내설된 급지용 카세트(1)에 용지 적재시 사용자가 용지받침판(4)을 하향으로 누루면 용지받침판(4)은 힌지축(3)을 중심으로 회동하면서 용지받침판(4) 밑면에서 토션스프링(9)에 탄지되어진 샤프트(8)가 카세트(1) 양측벽(5)에 형성된 가이드홀(6)을 따라 이동되어진다.When the user presses the paper support plate 4 downward when the paper is loaded in the paper feed cassette 1 with the paper presser installed, the paper support plate 4 rotates about the hinge axis 3 and the bottom of the paper support plate 4. The shaft 8 supported by the torsion spring 9 is moved along the guide hole 6 formed in the side wall 5 of the cassette 1.

상기 동작에 의해 용지받침판(4)을 사용자가 완전히 하향으로 누르게 되면 압착로울러(7)을 구비한 샤프트(8)가 슬라이드홀(6) 하단에 형성된 록킹부(12)에 위치하게 되어 용지받침판(4)이 이동된 상태를 유지하게 된다.When the user presses the paper support plate 4 completely downward by the above operation, the shaft 8 having the compression roller 7 is positioned at the locking part 12 formed at the bottom of the slide hole 6, thereby supporting the paper support plate ( 4) will remain moved.

상기와 같은 상태에서 급지용 카세트(1)의 용지받침판(4) 상면에 적재하고자 하는 용지를 적재하게 되고 적재된 용지의 선단 양쪽 모서리는 급지용 카세트(1)의 선단 양모서리에 설치된 분리조의 밑면에 위치하여진다.In the above state, the paper to be loaded is loaded on the upper surface of the paper support plate 4 of the paper feed cassette 1, and both edges of the loaded paper are bottom of the separation tank installed at both ends of the paper feed cassette 1; It is located in

상기와 같이 용지가 적재된 급지용 카세트(1)를 기기의 카세트 급지부에 밀어서 정착시키게 되면 급지용 카세트(1)가 완전 장착되기 직전에 로킹부(12)에 록킹된 샤프트(8)가 해제되는데 이때 급지부의 내측벽에 형성된 푸시에 샤프트(8)의 양단이 당접되게 되며, 당접된 상태에서 카세트(1)를 좀더 내측으로 밀어 놓으면 급지용 카세트(1)가 완전 장착됨과 동시에 샤프트(8)가 록킹부(12)에서 해제되어진다.When the paper feed cassette 1 loaded with paper is pushed and fixed to the cassette feeder of the machine as described above, the shaft 8 locked to the locking part 12 is released immediately before the paper feed cassette 1 is fully mounted. At this time, both ends of the shaft 8 are in contact with the push formed on the inner wall of the paper feeding unit. When the cassette 1 is pushed further inward in the contacted state, the paper cassette 1 is fully mounted and the shaft 8 is The locking portion 12 is released.

상기와 같은 상태에서 일측단이 돌출핀(11)과 타단이 샤프트(8)를 탄지하고 있던 토션스프링(9)의 탄성에 의해 샤프트(8)가 슬라이드홀(6)을 따라 상측으로 이동되면서 샤프트(8)에 설치된 가압로울러(7)가 용지받침판(4)을 가압하게 되어 급지용 카세트(1)에 적재된 용지중 최상단에 위치한 용지가 급지로울러에 의해 급지되어진다.In the state as described above, the shaft 8 is moved upward along the slide hole 6 by the elasticity of the torsion spring 9 whose one end is supported by the protruding pin 11 and the other end by the shaft 8. The pressure roller 7 installed in (8) presses the paper support plate 4 so that the paper located at the top of the paper loaded in the paper cassette 1 is fed by the paper feed roller.

상기와 같이 살펴본 본 고안은 용지받침판을 가압하는 스프링의 탄성을 록킹부에 의해 일시적으로 제어함으로써 용지 받침판에 용지를 손쉽게 적재할 수 있으며 급지부에 카세트 장착시 용지의 꾸겨짐이나 급지로울러에 의한 최상단부의 용지가 뒤로 밀려나는 것을 방지할 수 있다.The present invention as described above can easily load the paper on the paper backing plate by temporarily controlling the elasticity of the spring pressurizing the paper backing plate by the locking part, and when the cassette is attached to the paper feeding part, the top end of the paper packing or feeding roller The paper can be prevented from being pushed back.
