본 고안은 복사기 및 레이저 프린터의 급지부 조립구조에 관한 것으로, 특히 급지롤의 조립 및 교환 보수를 간단히 행할 수 있도록 한 급지부 조립구조에 관한 것이다.The present invention relates to a feeder assembly structure of a copying machine and a laser printer, and more particularly, to a feeder assembly structure that allows the assembly and replacement of the feed roll to be easily performed.

종래 복사기 및 레이저 프리터에 있어서는 제 4 도 및 제 5 도에 도시한 바와같이, 카세트(31)내에 용지(32)가 쌓여있고 이 용지 윗면에 급지롤(33)이 접해있다. 그리고 이 급지롤(33)은 구동 샤프트(34)에 끼워져서 고정핀(35)과 고정 E링(36)으로 조립된다. 이 급지롤(33)은 풀리(37)의 외주면에 부착되어 있는데 급지롤(33)은 고무이고, 풀리(37)는 플라스틱이다. 즉, 구동 샤프트(34)가 롤 풀리(37)의 내부 축공(38)에 끼워지는 식으로 조립된다. 그리고 구동 샤프트(34)는 본체 좌,우 플레임(39)에 부시(40)와 E링(41)으로서 회전가능케 설치되고 구동샤프트(34)의 한끝에는 구동기어(42)가 고정되어 있다. 38'는 핀(35)의 삽입공을 보인 것이다. 급지시에는 메인모터(43)의 구동력이 클러치(44)를 통해서 구동기어(42)에 전달됨에 따라 급지롤(33)이 구동한다.In the conventional copiers and laser fritters, as shown in Figs. 4 and 5, sheets 32 are stacked in the cassette 31 and the paper feed roll 33 is in contact with the upper surface of the sheets. The paper feed roll 33 is fitted to the drive shaft 34 and assembled with the fixing pin 35 and the fixing E ring 36. The paper feed roll 33 is attached to the outer circumferential surface of the pulley 37. The paper feed roll 33 is rubber, and the pulley 37 is plastic. That is, the drive shaft 34 is assembled in such a manner that it fits into the inner shaft hole 38 of the roll pulley 37. The drive shaft 34 is rotatably installed as the bush 40 and the E ring 41 on the left and right flames 39 of the main body, and the drive gear 42 is fixed to one end of the drive shaft 34. 38 'shows the insertion hole of the pin 35. During feeding, the feeding roll 33 is driven as the driving force of the main motor 43 is transmitted to the driving gear 42 through the clutch 44.

이러한 종래 급지부 구조에 있어서 급지롤(33)을 조립하는 경우에는 우선 구동 샤프트(34)에 구동 풀리(37)의 축공(38)을 끼우고 구동 샤프트(34)의 핀공(45)과 풀리(37)의 핀공(38')에 고정핀(35)를 끼우고 풀리(37)의 반대편에는 E링(36)을 채운다. 그 다음에 급지롤(33)이 조립된 구동 샤프트(34)의 좌측단부 또는 우측단부를 본체 좌,우 프레임(39)에 형성된 부시공(46)에 차례로 끼우고 그 구동샤프트(44)의 좌,우 끝에서 부시(40)을 삽입하여 부시공(46)에 고정한 뒤 링(41)을 조립하고 구동기어(42)를 체결하도록 되어있다.When assembling the feed roll 33 in the conventional feeder structure, the shaft hole 38 of the drive pulley 37 is first inserted into the drive shaft 34, and the pin hole 45 and the pulley 37 of the drive shaft 34 are inserted. Insert the fixing pin 35 into the pin hole (38 ') of the) and fill the E ring 36 on the opposite side of the pulley (37). Then, the left end or the right end of the drive shaft 34 on which the paper feed roll 33 is assembled is inserted into the bush hole 46 formed in the left and right frames 39 of the main body in turn, and the left side of the drive shaft 44. After inserting the bush 40 at the right end, the bush 40 is fixed to the bush hole 46, and then the ring 41 is assembled and the driving gear 42 is fastened.

그리고 사용중 급지롤(33)의 표면에 기름이나 이물질이 묻게되어 용지를 더렵히거나 미끄럼으로 인해 이송시키지 못하기 때문에 수리보수를 하거나 급지롤(33)의 수명이 다하여 교환할 필요가 있는 경우에는 조립의 역순으로 분해한다.If the surface of the feed roll 33 is in use and oil or foreign matter gets on it, and the paper cannot be transported due to dirt or slipping, it is necessary to repair or replace it when the life of the feed roll 33 is over. Decompose in reverse order.

그러나, 이와같은 종래 복사기의 급지부 조립구조는 급지롤을 조립하기가 불편하며 또한 수리보수 및 교환을 위해서는 구동기어, 부시 및 구동샤프트등 전 관련부품을 분해해야만 하는 난점이 있었다. 더욱이 본체 프레임에는 다른 구성부품들이 함께 복잡하게 조립되어 있어서 제조립이 번거롭게 되는 문제점이 있었다.However, such a feeder assembly structure of the conventional copier is inconvenient to assemble the feed roll, and also has a difficulty in disassembling all related parts such as a drive gear, a bush and a drive shaft for repair and replacement. In addition, there is a problem in that the main body frame is complicated to assemble the other components together, manufacturing is cumbersome.

본 고안은 상기한 바와같은 종래의 결함을 해소하기 위하여 안출한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to solve the conventional defects as described above, when described in detail by the accompanying drawings as follows.

제 1 도 내지 제 3 도에 도시한 바와같이, 복사기 본체 내부의 좌,우 프레임(1)에 형성한 부시공(2)에 부시(3)를 각각 고정하고 각 부시(3)에는 급지롤(4)이 양측으로 고정되는 샤프트(5)의 양측단부를 삽입하여 E링(6)으로 각각 고정하며 샤프트(5)의 단부에는 구동기어(7)를 고정한 복사기의 급지부에 있어서, 내륜(8)과 외륜(9)을 연결부(10)로 연결함과 아울러 내륜(8)이 중심보다 일정간격(E)만큼 형성하고 내륜(8)의 내륜(8)의 내주면 중간부에는 고정돌기(11)를 형성한 플라스틱제 롤풀리(12)를 성형하는 동시에 외륜(9)의 외주면에 고무제 급지롤(4)을 부착하며, 샤프트(5)의 양측부에는 상기 롤풀리(12)의 고정돌기(11)가 삽입 고정되는 고정홈(13)을 형성하여서된 것으로, 도면에서 미설명 부호 14는 급지 카세트, 15는 용지, 16은 메인모터, 17은 클러치를 각각 보인 것이고, 18,18'는 수차 급지롤, 19는 용기 안내판, 20,20'는 레지스터롤, 21은 수차 센서를 각각 보인 것이며, 22는 레지스터 센서를 보인 것이다.As shown in Figs. 1 to 3, the bushes 3 are respectively fixed to the bush holes 2 formed in the left and right frames 1 in the copier main body, and the feed rolls are formed on the bushes 3, respectively. Inner ring (8) in the feed section of the copier in which the opposite ends of the shaft (5), which are fixed to both sides, is inserted and fixed with E-rings (6), and the drive gear (7) is fixed to the ends of the shaft (5). And the outer ring 9 are connected to the connection part 10, and the inner ring 8 is formed by a predetermined distance (E) from the center, and the fixing protrusion 11 is formed at the middle of the inner circumferential surface of the inner ring 8 of the inner ring 8. At the same time, the formed plastic roll pulley 12 is molded, and a rubber feeding roll 4 is attached to the outer circumferential surface of the outer ring 9, and the fixing protrusions 11 of the roll pulley 12 are attached to both sides of the shaft 5. ) Is to form a fixing groove 13 is inserted and fixed, in the drawings, reference numeral 14 is a paper cassette, 15 is a paper, 16 is the main motor, 17 is showing the clutch And, 18,18 'are aberration feed roll, 19 is a container guide plate, 20 and 20' is the register roll 21 will showing the aberration sensor, respectively, 22 is a register showing a sensor.

이와같은 본 고안에 따라서 급지롤을 조립하는 경우에는 제일먼저, 구동 샤프트(5)에 아무것도 조립하지 않은체 구동 샤프트(5)를 제 1 도의 P방향으로 양축 프레임(1)의 부시공(2)에 끼운 후 부시(3)를 끼우고 E링(6)으로 체결한다. 이후에 샤프트(5)의 우측 끝에 구동기어(7)를 고정하고 제 2 도와 같이 조립된 샤프트(5)에 급지롤(4)을 손으로 잡아서 R방향으로 밀어 넣으면 샤프트(5)의 고정홈(13)에 롤풀리(12)에 고정돌기(11)가 삽입되고 롤풀리(12)의 내륜(8)이 늘어나면서 샤프트(5)의 외주면을 감싸게 된다. 이때 내륜(8)은 중심에서 E만큼 길게 형성되어 있으므로 손으로 뽑지 않는한 뽑히지 않고 고정돌기(11)에 의하여 롤풀리(12) 및 급지롤(4)이 헛돌지 않게 된다.In the case of assembling the paper feed roll according to the present invention, first, the bushing hole 2 of the biaxial frame 1 in the P direction of FIG. 1 is mounted with the body drive shaft 5 in which nothing is assembled to the drive shaft 5. Insert it into the bush (3) and fasten it with the E ring (6). Thereafter, the drive gear 7 is fixed to the right end of the shaft 5 and the feed roll 4 is pushed in the R direction by the hand holding the feed roll 4 to the shaft 5 assembled with the second tile. The fixing protrusion 11 is inserted into the roll pulley 12 and the inner ring 8 of the roll pulley 12 extends to surround the outer circumferential surface of the shaft 5. At this time, since the inner ring 8 is formed as long as E from the center, the roll pulley 12 and the paper feed roll 4 do not turn away by the fixing protrusion 11 without being pulled out unless pulled by hand.

필요에 따라 급지롤(4)를 교환 및 수리보수하는 경우에는 제 3 도와 같이 카세트(14)를 제거한 뒤 손으로 급지롤(4) 및 롤풀리(12)를 R역방향으로 뽑아내면 간단하게 분리가 완료된다.If necessary, when replacing or repairing the feed roll 4, remove the cassette 14 as shown in the third drawing, and then pull out the feed roll 4 and the roll pulley 12 by hand in the R reverse direction. Is done.

필요에 따라 급지롤(4)를 교환 및 수리보수하는 경우에는 제 3 도와 같이 카세트(14)를 제거한 뒤 손으로 급지롤(4) 및 롤풀리(12)를 R역방향으로 뽑아내면 간단하게 분리가 완료된다.If necessary, when replacing or repairing the feed roll 4, remove the cassette 14 as shown in the third drawing, and then pull out the feed roll 4 and the roll pulley 12 by hand in the R reverse direction. Is done.

그리고 제조립시에도 급지롤(4) 및 롤풀리(12) 일체물을 본체에 조립된 샤프트(5)에 끼워 넣으면 된다.In the case of manufacturing, the feed roll 4 and the roll pulley 12 integral part may be inserted in the shaft 5 assembled to the main body.

상기한 바와 같은 본 고안은 내, 외륜 및 고정돌기를 가지는 롤폴리와 급지롤을 일체로 형성하여 샤프트에 형성한 고정홈에 간단히 조립, 분리할수 있도록 하였으므로 종래기술에 비하여 급지롤의 조립 및 분리가 월등히 간단용이해지고 효율적인 이점이 있다.The present invention as described above is to form and integrate the roll poly and the feed roll having the inner, outer ring and the fixing projection integrally in the fixed groove formed in the shaft, so that the assembly and separation of the feed roll compared to the prior art It is much simpler and more efficient.
