본 고안은 복사기에서 용지를 급지하며 인쇄된 용지를 이송시키는 반송부를 구동하기 위한 장치에 관한 것으로서, 특히 하나의 벨트를 사용하여 구동시킬수 있도록 한 것이다.The present invention relates to an apparatus for driving a conveying unit for feeding paper and feeding printed paper in a copier, and in particular, to be driven using one belt.

종래에 복사기에는 최초에 용지를 급지하기 위한 구동장치와 감광드럼의 화상을 용지에 인쇄한후 인쇄된 용지를 반송하기 위한 반송부를 구동하기 위한 장치가 별도의 구동장치에 구동되었다.Conventionally, in the copier, a driving device for initially feeding paper and an apparatus for driving a conveying unit for transporting printed paper after printing an image of a photosensitive drum on the paper are driven by separate driving devices.

즉 별도의 구동모터에 의해 각기 구동하게 되므로 전력의 낭비가 심하며 급지부와 반송부의 이송속도가 일치하지 않을 경우 잼(Jam)발생요인이 되었다.In other words, since each drive is driven by a separate drive motor, waste of power is severe and jam occurs when the feeding speeds of the feeder and the carrier do not coincide.

또한 모터의 구동력을 기어와 전자식 클러치의 연결에 의해 구동되므로 일정한 선속도를 지니지 못하고 노이즈 현상이 발생한다.In addition, since the driving force of the motor is driven by the connection between the gear and the electronic clutch, a noise phenomenon occurs without a constant linear velocity.

본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로 급지부 구동로울러와 반송벨트를 구동하는 기어를 하나의 타이밍 벨트를 이용하여 구동시키므로서 급지부와 반송부를 일정한 속도로 구동시켜 노이즈의 발생을 억제하며, 잼발생을 미연에 방지토록 함을 목적으로 한다.The present invention was devised to solve the above problems, and the feed unit driving roller and the gear for driving the conveying belt are driven by using a single timing belt, thereby suppressing the occurrence of noise by driving the feed unit and the conveying unit at a constant speed. It aims to prevent jams in advance.

상기와 같은 목적을 달성하기 위한 본 고안의 목적을 첨부된 도면을 참조하여 설명하면 다음과 같다.Referring to the accompanying drawings, the purpose of the present invention for achieving the above object is as follows.

급지부(10)와 반송부(20)를 이루는 로울러(11, 12, 13)들은 프레임(30a, 30b)에 의해 지지되며 상기 로울러들을 구동하기 위한 구동기어들(14, 15, 16)을 하나의 타이밍벨트(21)로서 연결하여서 된 것으로 도면중 미설명부호 22는 벨트의 장력을 조절하기 위한 아이들 풀리이다.The rollers 11, 12 and 13 constituting the paper feeding portion 10 and the conveying portion 20 are supported by the frames 30a and 30b, and the driving gears 14, 15 and 16 for driving the rollers are one. The reference numeral 22 in the drawing, which is connected as the timing belt 21, is an idle pulley for adjusting the tension of the belt.

이와같이 구성된 본 고안의 작용효과는 모타가 구동함에 따라 급지로울러(11)를 구동시킴에 따라 본체 측벽에 설치되는 카세트로 부터 용지를 본체측으로 급지하게 된다.The effect of the present invention configured as described above is to feed the paper to the main body side from the cassette installed on the side wall of the main body as the feed roller 11 is driven as the motor is driven.

이와같이 급지부(10)로 부터 급지된 용지는 감광드럼의 하측을 지나면서 감광드럼에 토너로 현상된 상을 전사한후 정착부로 이송하기 위하여 반송부(20)를 보내게 된다.In this way, the paper fed from the paper feeding section 10 passes the lower side of the photosensitive drum and transfers the image developed by the toner to the photosensitive drum, and then sends the conveying section 20 to transfer to the fixing section.

상기 반송부(20)는 인쇄된 용지를 얹어 정착부로 이송시키기 위하여 구동로울러(11)와 구동로울러(12, 13)를 감싸는 반송벨트(25)로 구성된다.The conveying unit 20 is composed of a conveying belt 25 surrounding the driving roller 11 and the driving rollers 12 and 13 in order to load the printed paper to the fixing unit.

이때 반송벨트(25)로 로울러(12, 12')가 구동함에 따라 로울러(13, 13')를 구동시키게 되어 용지가 얹힌 상태에서 용지를 정착부 측으로 이송시키게 된다.At this time, as the rollers 12 and 12 'are driven by the conveyance belt 25, the rollers 13 and 13' are driven to transfer the paper to the fixing unit side while the paper is loaded.

이때 급지로울러(11)를 구동하기 위한 구동기어(14)로 부터 하나의 타이밍벨트(21)에 의해 반송로울러 구동기어(16)로 연결되어 연동이 구동되므로 구동길이가 같아지게 되어 용지의 반송을 원활하게 한다.At this time, since the interlocking is driven by driving the feed roller 11 from the drive gear 14 for driving the paper feed roller 11 to the transfer roller drive gear 16 by one timing belt 21, the drive length is the same and conveys the paper. Make it smooth.

이때 타이밍벨트(21)의 장력을 조절하기 위하여 아이들 풀리(22)가 프레임(3a)에 고정되어 있어 아이들 풀리(22)의 위치조정으로 타이밍 벨트(21)의 장력을 적절히 조절할 수가 있게 된다.At this time, the idle pulley 22 is fixed to the frame 3a to adjust the tension of the timing belt 21, so that the tension of the timing belt 21 can be properly adjusted by adjusting the position of the idle pulley 22.

상기한 바와같이 본 고안에 의하면 하나의 타이밍벨트를 이용하여 급지부와 반송부를 동시에 구동시키게 되므로 구동모타의 수를 줄일 수 있어 전력의 낭비를 줄이고 부피를 축소할 수 있을뿐만 아니라 구동속도를 일정하게 맞출수 있어 복사시 잼발생을 줄일수 있다.As described above, according to the present invention, since the feeder and the carrier are driven at the same time by using one timing belt, the number of driving motors can be reduced, thereby reducing the waste of power, reducing the volume, and keeping the driving speed constant. It can reduce the occurrence of jam when copying.
