1 : 카세트 2 : 힌지축1 cassette 2 hinge shaft
3 : 지지판 4 : 후단 가이드3: support plate 4: rear end guide
5 : 지지간 6 : 분리조5: support part 6: separation tank

본 고안은 복사기의 급지용 카세트에서 용지를 이송로울러에 밀착시키는 지지판의 회전중심이 되는 힌지축의 위치를 구조적으로 변환시켜 회전중심의 이동거리를 적재된 용지의 량에 관계없이 일정하게 하여 순조롭게 급지를 이룰수 있게 하기 위한 장치에 관한 것이다.The present invention structurally converts the position of the hinge axis, which is the center of rotation of the support plate that adheres the paper to the feed roller, in the cassette for feeding the copier, thereby smoothly feeding the center of rotation by keeping the distance of rotation center constant regardless of the amount of paper loaded. A device for making this possible.
종래에는 카세트(10)내부에 용지지지판(11)을 후방하단에 구멍을 갖는 지지간(12)과 축벽내측에 형성된 힌지축(13)에 삽입설치하고 상기 지지판(11)를 상향으로 밀어주기 위한 스프링(14)이 바닥면 앞쪽에 설치되어 상기 지지판(11)을 상향으로 탄지하게 된다.In the related art, a paper support plate 11 is inserted into a support shaft 12 having a hole at a rear lower end of the cassette 10 and a hinge shaft 13 formed in the shaft wall, and the support plate 11 is pushed upward. The spring 14 is installed in front of the bottom surface to support the support plate 11 upward.
상기와 같이 이루어진 종래의 기술은 카세트(10)내부에 설치된 지지판(11)위에 용지(15)를 적재하게 되면 카세트(10)바닥면 앞쪽에 설치된 스프링(14)에 의해 지지판(11)이 지지되어 용지(15)가 분리조(16)사이에서 위치하게 된다. 상기와 같은 상태에서 카세트(10)를 기기의 급지부에 삽입시키면 이송로울러(17)에 의해 가장선단에 위치한 용지(15)부터 이송로울러(17)에 의해 순차적으로 급지되게 된다.According to the related art, when the paper 15 is loaded on the support plate 11 installed inside the cassette 10, the support plate 11 is supported by a spring 14 installed in front of the bottom surface of the cassette 10. The paper 15 is positioned between the separating tanks 16. When the cassette 10 is inserted into the paper feeder of the machine in the above state, the feed rollers 17 are sequentially fed by the feed rollers 17 from the sheet 15 positioned at the front end by the feed rollers 17.
상기와 같은 상태에서 연속되는 복사작업에 의하여 적재된 용지(15)의 량이 적어져 스프링(14)에 탄지된 지지판(11)이 힌지축(13)를 중심으로 순차적으로 상향으로 이동하게 된다. 이때 제1도(b)에 나타난 바와 같이 상향으로 이동되는 지지판(11)의 선단이 최하단에 있을때와 최상단에 위치할때의 거리(A)변화로 용지(15)가 분리조(16)에 압접되는 부분이 차이(A)가 생기게 된다.In the above state, the amount of the paper 15 loaded by the continuous copying operation decreases so that the support plate 11 supported by the spring 14 is sequentially moved upwardly about the hinge shaft 13. At this time, as shown in FIG. 1 (b), the paper 15 is press-contacted to the separation tank 16 by the change of the distance A when the tip of the support plate 11 moved upward is located at the bottom and at the top. The difference becomes A.
상기와 같은 종래기술의 카세트는 지지판의 힌지축이 하단에 위치하고 있어 적재된 용지의 량에 따라 스프링에 의해 지지판이 상부로 이동되어져 분리조에 압접되는 부위의 차가 커져 잼발생과 용지가 중첩되어 중송되는 문제점이 있었다.In the cassette of the prior art as described above, the hinge shaft of the support plate is located at the bottom, and the support plate is moved upward by the spring according to the amount of the loaded paper, so that the difference between the parts pressed by the separation tank increases and jams are overlapped with the paper. There was a problem.
본 고안은 상기와 같은 문제점을 해소하기 위하여 안출한 것으로서 용지를 이송로울러에 밀착시키는 지지판의 회전중심이 되는 힌지축의 위치를 구조적으로 변화시켜 회전중심의 이동거리를 용지의 량에 관계없이 일정한 거리를 유지하여 분리조에 안정되게 압접하고 순조롭게 용지를 이송시켜 잼 발생 및 중송을 방지하는데 본 고안의 목적이 있다.The present invention devised to solve the above problems, by structurally changing the position of the hinge axis, which is the center of rotation of the support plate, which closely adheres the paper to the feed rollers, so that the moving distance of the center of rotation can be fixed regardless of the amount of paper. It is an object of the present invention to prevent jams and feeding by holding paper stably and stably feeding the separation tank to smoothly transfer the 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) 후방 내측벽 중앙에 힌지축(2)를 형성하고 지지판(3) 후단에 상향으로 직교하여 가이드(4)를 형성하며 상기 가이드(4) 양측 중앙에 구멍을 갖는 지지간(5)이 외향으로 형성되어 힌지축(2)에 회동 가능하게 설치되며 카세트(1) 앞쪽 상단 양모서리에 분리조(6)가 형성되며 바닥면의 스프링(7)에 의해 지지되어져 지지판(3) 선단 밑면을 탄지하게 구성되었다.A support shaft 5 having a hinge shaft 2 formed at the center of the rear inner wall of the cassette 1 and a guide 4 formed at right angles to the rear end of the support plate 3, and having holes at both centers of the guide 4, respectively. It is formed outwardly and is rotatably installed on the hinge shaft (2), and the separation tank (6) is formed at the upper both corners in front of the cassette (1), and is supported by the spring (7) at the bottom to support the bottom of the support plate (3). It was constructed hard.
미설명부호 8은 이송로울러 9는 용지이다.Reference numeral 8 is a conveyance roller 9 is paper.
상기와 같이 구성된 본 고안의 작용효과를 살펴보면 다음과 같다.Looking at the effect of the present invention configured as described above are as follows.
카세트(1)내부에 용지(9)를 장착할 경우 지지판(3)상면에 용지(9)를 얹은후 용지(9)의 선단모서리 부분이 카세트(1) 전방 상단 양모서리에 형성된 분리조(6)하단 밑면으로 위치하여 압압하던 힘을 제거하면 스프링(7)의 탄력에 의하여 상향으로 이동한다.When the paper (9) is mounted inside the cassette (1), after separating the paper (9) on the upper surface of the support plate (3), the separation tank (6) in which the leading edge portion of the paper (9) is formed at the upper edge of the front of the cassette (1). ) Removed the pressing force to the bottom of the bottom to move upward by the elasticity of the spring (7).
이와 같은 상태에서 이송로울러(8)가 구동하여 최상단의 용지(9)를 급지하게 되는 것이면 이후 최상단에 용지(9)가 급지됨에 따라스프링(7)의 탄력에 의해 지지판(3)이 용지(9)의 두께만큼 상측으로 이송하며 이때에도 전술한 바와 같은 동작이 일어나게 된다.In this state, if the feed roller 8 is driven to feed the uppermost sheet 9, the sheet 9 is fed to the uppermost layer, and as a result, the support plate 3 is not supported by the spring 7. It is conveyed upward by the thickness of) and also the same operation as described above occurs.
상기와 같은 동작되는 지지판(3)의 회전 중심을 중간에 위치하게 설치하여 회전중심을 위로 이동시켜 중으로서 용지(9)의 적재량에 따른 지지판(3)의 회전중심 거리를 향상 일정하게 하여 분리조(6)에 안정되게 압압하게 되어 용지의 잼 발생 및 중송을 방지하게 된다.Separation tank to improve the rotation center distance of the support plate 3 according to the loading amount of the paper (9) by moving the center of rotation up to the center of rotation of the support plate (3) operated as described above in the middle It is pressed against (6) stably, and jams and paper feeding of paper are prevented.
상기한 바와 같이 본 고안에 의하면 지지판의 회전중심을 위로 이동시킴으로서 용지의 량에 관계없이 용지가 분리조에 안전하게 압착되며 잼과 중송을 방지할 수 있어 급지장치의 신뢰도를 높일 수 있다.As described above, according to the present invention, by moving the rotation center of the support plate upward, the paper is securely crimped to the separation tank regardless of the amount of paper, and jams and heavy feeding can be prevented, thereby increasing the reliability of the paper feeder.
