본 고안은 복사기나 팩시밀리 등과 같은 사무기기에 채용되는 기록지의 급지장치에 관한 것으로서, 특히 급지롤러의 마모로 마찰력이 저하되어 급지력이 떨어질 때 이를 조절하여 기록지의 급지가 원활하게 이루어지도록 한 급지장치에 관한 것이다.The present invention relates to a paper feeder used for office equipment such as a copy machine or a facsimile, and in particular, a paper feeder for smoothly feeding a paper feeder by adjusting the frictional force due to abrasion of the paper feed roller to reduce the paper feed force. It is about.
일반적으로 복사기, 팩시밀리 등 OA기기에는 기록지를 수납하는 기록지 카세트가 채용되어 있으며, 그 기록지는 급지캠에 의해서 카세트로부터 취출되고 급지롤러에 의해 장치내부로 급지된다.Generally, a recording paper cassette for storing recording paper is employed in an OA device such as a copying machine or a facsimile, and the recording paper is taken out of the cassette by a feeding cam and fed into the apparatus by a feeding roller.
여기서 기록지는 제1도에 도시된 바와 같이 시계방향으로 회전되는 제1로을러(3)와 급지시키고자 하는 기록지(1)사이의 마찰력이 제2로울러(4)와 기록지(2)사이의 마찰력보다 크게 되도록 설정함으로써 기록지(1)만이 급지되도록 된다.Here, as shown in FIG. 1, the frictional force between the first roller 3 rotated in the clockwise direction and the recording paper 1 to be fed is the frictional force between the second roller 4 and the recording paper 2. By setting it to be larger, only the recording sheet 1 is fed.
그런데, 급지장치의 장시간 사용시 급지롤러가 마모되어 롤러사이의 압착력이 작아지게 되어 기록지 잼(JAM) 및 두 장의 기록지가 한 번에 급지되게 되고, 급지롤러의 편마모시에는 기록지가 비스듬히 급지되는 등 원고의 이송이 원활하지 않게 되는 문제점이 있다.However, when the paper feeder is used for a long time, the paper feed roller wears down, and the compressive force between the rollers is reduced, so that the paper jam (JAM) and two recording papers are fed at once, and the paper is fed at an angle when the paper feed roller is worn. There is a problem that the transfer of is not smooth.
본 고안은 상기의 문제점을 해결하기 위하여 안출된 것으로서, 급지롤러의 마모에도 불구하고 기록지의 급지가 원활하게 이루어지도록 한 급지장치를 제공하는데 그목적이 있는 것이다.The present invention is devised to solve the above problems, and it is an object of the present invention to provide a paper feeding device for smoothly feeding the recording paper despite the wear of the paper feed roller.
상기 목적을 달성하는 본 고안은 상, 하부 두 급지 롤러사이로 기록지를 금지시키는 급지장치에 있어서, 상기 상, 하부 급지롤러중 적어도 어느 한 급지롤러에 다른 급지롤러에 대한 압착력을 조절할 수 있는 압착력 조절수단이 구비되어 된 것을 특징으로 한다.The present invention to achieve the above object is a paper feeding device forbidding the recording paper between the upper, lower paper feed rollers, the pressing force adjusting means for adjusting the pressing force of the other paper feed rollers to at least one of the upper, lower paper feed rollers It is characterized in that it is provided.
이하 첨부된 도면을 참조하면서 본 고안에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 고안에 따른 급지장치를 개략적인 분리사시도로 나타낸 제2도 및 작동도를 나타낸 제3도를 참조하면, 상, 하부 급지롤러(50)(60)가 프레임(11)에 지지되어 있고, 하부 급지롤러(60)에는 상부 급지롤러(50)에 대한 압착력을 조절할 수 있는 압착력 조절수단이 구비되어 있다.Referring to FIG. 2 of the paper feeding apparatus according to the present invention and FIG. 3 of the operation diagram, the upper and lower paper feed rollers 50 and 60 are supported on the frame 11, and Feeding roller 60 is provided with a pressing force adjusting means for adjusting the pressing force for the upper feed roller (50).
상기 압착력 조절수단은 상기 하부 급지롤러(60)가 상하로 이동될 수 있도록 프레임(11)에 장공(13)을 형성하고, 상기 상, 하부 급지롤러(50)(60)를 상호 밀착시키도록 축(51)(61)들에 연결되는 스프링부재(70)와, 상기 프레임(11)에 회전가능하게 지지되고 그 일단이 상기 하부 급지롤러(60)와 축(61)에 연결되는 작동레버(80)와, 상기 프레임(11)에 슬라이딩 가능하게 지지되는 랙기어(30)와, 상기 랙기어(30)를 이동시키는 워엄기어(21)가 마련된 조작노브(20)와, 상기 랙기어(30)와 작동레버(80)의 타단을 연결하는 연결부재로서 와이어(40)를 구비하여서, 랙기어(30)의 이동에 따라 작동레버(80)가 회전되고 이에 따라 하부 급지롤러(60)가 상부 급지롤러(50)에 대해 압착력이 가감되도록 구성하였다.The pressing force adjusting means forms a long hole 13 in the frame 11 so that the lower paper feed roller 60 can be moved up and down, and the upper and lower paper feed rollers 50, 60 are in close contact with each other. A spring member 70 connected to the 51 and 61 and an actuating lever 80 rotatably supported by the frame 11 and having one end connected to the lower feed roller 60 and the shaft 61. ), An operation knob 20 provided with a rack gear 30 slidably supported by the frame 11, a worm gear 21 for moving the rack gear 30, and the rack gear 30. And a wire 40 as a connecting member for connecting the other end of the operation lever 80 to the operation, the operation lever 80 is rotated in accordance with the movement of the rack gear 30, and accordingly the lower feed roller 60 is the upper feed It was comprised so that the pressing force with respect to the roller 50 may be added or subtracted.
이와 같이 구성된 본 고안에 따른 급지장치는 다음과 같은 작용효과를 가진다. 먼저 조작노브(20)를 조절하여 랙기어(30)를 우측으로 이동시켜서 작동레버(80)를 회전시켜 하부 급지롤러(60)가 상부 급지롤러(50)에 대해 적당한 압착력을 가지도록 한다. 이때 스프링부재(70)는 약간 인장된 상태로 있게 된다. 이후 상, 하부 급지롤러(50,60)사이로 기록지(미도시)를 급지시키는 도중 급지롤러(50)(60)의 마모로 두 롤러 사이의 압착력이 떨어지게 되면, 조작노브(20)를 돌려서 랙기어(30)를 좌측으로 이동시킨다. 이때 작동레버(80)는 스프링부재(70)의 복원력으로 시계방향으로 회전되면서 하부 급지롤러(60)가 상부 급지롤러(50)측으로 이동되어 압착력을 증가시킨다. 즉, 본 고안에 따른 급지장치는 급지롤러(50)(60)의 마모시 조작노브(20)로 조작하여 하부 급지롤러(60)를 이동시켜서 두 급지롤러 (50)(60) 사이의 압착력을 조절함으로써 기록지를 원활하게 급지시킬 수 있도록 한다.The paper feeding device according to the present invention configured as described above has the following effects. First, by adjusting the operation knob 20 to move the rack gear 30 to the right to rotate the operation lever 80 so that the lower paper feed roller 60 has an appropriate pressing force against the upper paper feed roller (50). At this time, the spring member 70 is in a slightly tensioned state. Then, when the pressing force between the two rollers drops due to the wear of the paper feed rollers 50 and 60 while feeding the recording paper (not shown) between the upper and lower paper feed rollers 50 and 60, the operation knob 20 is turned to the rack gear. Move (30) to the left. At this time, the operation lever 80 is rotated clockwise by the restoring force of the spring member 70, the lower feed roller 60 is moved to the upper feed roller 50 side to increase the pressing force. That is, the paper feeding device according to the present invention operates the operation knob 20 when the paper feed rollers 50 and 60 are worn to move the lower paper feed roller 60 to thereby compress the pressing force between the two paper feed rollers 50 and 60. By adjusting, the recording paper can be fed smoothly.
상술한 바와 같이 본 고안에 따른 급지장치는 장시간 사용할 때 급지롤러가 마모되어 롤러 사이의 압착력이 작아지게 되어 기록지 잼(JAM) 및 두 장의 기록지가 한 번에 급지되게 되고, 급지롤러의 편마모시에는 기록지가 비스듬히 급지되는 등 원고의 이송이 원활하지 못한 종래의 문제점을 해결한다.As described above, in the paper feeding device according to the present invention, when the paper feed roller is worn out for a long time, the pressing force between the rollers is reduced, so that the recording paper jam (JAM) and two recording papers are fed at once, It solves the conventional problem that the conveyance of an original is not smooth, such as recording paper being fed at an angle.
이상에서 설명한 바와 같이 본 고안은 두 급지롤러(50)(60) 사이의 압착력을 조절할 수 있는 수단을 구비하여 기록지를 원활하게 급지시킬 수 있도록 하는 기록지 급지장치를 제공한다.As described above, the present invention provides a recording sheet paper feeding apparatus which is capable of smoothly feeding the recording sheet by providing a means for adjusting the pressing force between the two sheet feeding rollers 50 and 60.
