본 고안은 복사기기에서 용지를 계속해서 공급할수 있는 카세트 급지장치에 관한 것으로, 특히 픽-업(Pick-Up)로울러가 원형일 경우 적재된 종이가 로울러와의 걸림이 없이 급지부 몸체에 안착될수 있도록하는 복사기기의 급지가이드 장치에 관한 것이다.The present invention relates to a cassette feeder that can continuously feed paper from a copying machine. Especially, when the pick-up roller is circular, the loaded paper can be seated on the feeder body without jamming with the roller. It relates to a feed guide device of a copying machine.

카세트는 종이를 적재하고 있기 때문에 종이에 픽업 로울러가 얹어져야 하는 급지부 기능의 요구상 제1도(b)와 같은 원형 로울러 일때에는 카세트를 급지부에 삽입하는 과정에서 맨위에 위치한 종이가 삽입되지 못하는 현상이 생긴다.Since the cassette is loaded with paper, the top paper cannot be inserted in the process of inserting the cassette into the paper feeder when the circular roller as shown in FIG. 1 (b) is required because the pickup roller should be placed on the paper. This occurs.

따라서 이를 해결하기 위하여 원형로울러를 반달형으로 형성시켜 제1도(a)와 같이 설치하였다.Therefore, to solve this problem, a circular roller was formed in a half moon shape and installed as shown in FIG.

그러나, 반달형 로울러를 쓸수 없는 특수한 경우에는 제1도(c)와 같이 급지부에 가이드홈을 굴곡지게 형성시켜 카세트 삽입시 종이가 원형 로울러에 닿지 않고 완전히 삽입한 상태에서 원형 로울러에 압지되게 하였다.However, in a special case in which the vandal type roller cannot be used, the guide groove is bent in the paper feeding portion as shown in FIG. 1 (c) so that the paper is pressed into the circular roller while the cassette is completely inserted without touching the circular roller.

이러한 제1도(c)의 경우 카세트가 수평상태에서 들어가다가 굴곡진 가이드 홈 때문에 카세트가 흔들리는 염려가 있고, 가이드와 카세트 사이에서 마모가 많이 발생되는 문제가 있었다.In the case of FIG. 1 (c), the cassette enters in a horizontal state, and there is a concern that the cassette is shaken due to the curved guide groove, and a lot of wear occurs between the guide and the cassette.

이러한 종래 구성상의 문제점을 해결하기 위하여 안출한 본 고안은 원형 로울러를 사용하는 급지부 몸체에 카세트가 끼워질때 종이가 원형 로울러와 닿지 않게 삽입되고, 완전히 끼워진 상태에서 카세트가 회동할수 있게 급지부 몸체에 가이드홈을 구성하여 카세트의 완전 삽입시에만 종이가 원형 로울러에 닿도록 한것으로, 이를 첨부도면과 함께 상세하게 설명하면 다음과 같다.The present invention devised to solve the problems of the conventional configuration is inserted into the paper feeder body using a circular roller so that the paper does not touch the circular roller, the guide groove in the feeder body so that the cassette can be rotated in the fully inserted state It is configured so that the paper touches the circular roller only when the cassette is completely inserted, which will be described in detail with the accompanying drawings.

제2도는 본 고안의 급지장치에 대한 단면구조도인데, 급지부 몸체(1)의 양측면에 가이드홈(6)를 절개하여 형성한다.2 is a cross-sectional structural view of the paper feeder according to the present invention, and is formed by cutting guide grooves 6 on both sides of the paper feeder body 1.

상기의 가이드홈(6)을 형성함에 있어, 급지부 몸체(1)의 원형로울러(2) 카세트(8)의 상면이 닿지않는 위치를 절개하되 경사지게 절개하여 형성하고, 가이드홈(6)의 선단에는 원형 로울러 방향으로 이동할수 있는 고정홈(7)을 형성하는데, 가이드 홈(6)에서 경사지게 형성한다.In forming the guide groove (6), the circular roller (2) of the feeder body (1) is formed by cutting the inclined position that is not in contact with the upper surface of the cassette (8), at the tip of the guide groove (6) The fixing groove 7 is formed to move in a circular roller direction, and is formed to be inclined at the guide groove 6.

그리고 급지몸체(1)에는 카세트(8)의 하단이 통과하는 위치에 카세트 밀대(4)가 위치하도록 카세트 밀대(4)의 축(3)을 축 고정하며 카세트 밀대(4)와 급지부 몸체(1)의 바닥면 사이로 인장스프링(5)을 걸어 카세트 밀대(4)가 탄력회동하게 된다. 도면중 미설명부호 10은 케이스이다.The cassette body 4 is fixed to the paper feeding body 1 such that the shaft 3 of the cassette paper 4 is positioned so that the cassette paper 4 is positioned at the position where the lower end of the cassette 8 passes. The tension spring (5) hangs between the bottom surface of the) and the cassette pusher (4) is elastically rotated. Reference numeral 10 in the drawings is a case.

이러한 구성으로 이루어진 본 고안은 먼저 카세트(8)에 종이를 채워 넣고 카세트(8)를 급지부 몸체(1)에 접근시키면서 카세트(8)선단으로 카세트 밀대(4)를 밀면 제3도(a)와 같이 밀대(4)가 회전하여 카세트(8)의 저면으로 접촉하게 되고 가이드핀(9)이 가이드홈(6)으로 끼워지게 된다.The present invention made up of such a configuration first fills the paper in the cassette 8 and pushes the cassette pusher 4 to the end of the cassette 8 while the cassette 8 approaches the paper feeder body 1, and the third drawing (a) and Likewise, the push rod 4 is rotated to contact the bottom surface of the cassette 8 and the guide pin 9 is fitted into the guide groove 6.

이러한 상태에서 카세트(8)를 밀면 원형로울러(2)와 카세트 맨위의 종이는 접촉하지 않는 상태로 삽입되어 가이드홈(6)끝에서 가이드핀(9)이 걸려 카세트(8)의 삽입이 정지한다.When the cassette 8 is pushed in such a state, the circular roller 2 and the paper on the top of the cassette are inserted without contact, and the guide pin 9 is caught at the end of the guide groove 6 to stop the insertion of the cassette 8. .

이때 카세트(8)를 취부하던 손을 놓으면 삽입시 밀대의 회전으로 인장되었던 인장스프링(5)이 오므라들면서 카세트 밀대(4)의 선단으로 카세트(8)를 들려올리게된다.At this time, when the user releases the cassette 8, the tension spring 5, which was tensioned by the rotation of the push rod, is lifted, and the cassette 8 is lifted up to the tip of the cassette push rod 4.

따라서 카세트(8)의 가이드핀(9)을 가이드홈(6)에서 경사진 고정홈(7)으로 이동시키게 되므로, 그때에 원형로울러(2)와 카세트(8)에 적재한 종이가 압지하게 된다.Therefore, since the guide pin 9 of the cassette 8 is moved from the guide groove 6 to the inclined fixing groove 7, the paper loaded in the circular roller 2 and the cassette 8 is pressed at that time. .

종이가 다 소모된 위에 카세트(8)를 급지부 본체(1)로 부터 뽑아낼때에는 삽입하던 역순으로 먼저 카세트(8)의 상단을 밀어 가이드핀(9)이 고정홈(7)에서 가이드홈(6)위치로 오게한후 카세트를 잡아뽑으면 본체에서 카세트가 분리됨과 동시에 카세트 밀대(4)는 인장스프링(5)의 당김으로 선단이 가이드홈 위치로 회동하게 된다.When the cassette 8 is pulled out of the feeder body 1 on the paper, the guide pin 9 moves from the fixing groove 7 to the guide groove 6 by pushing the top of the cassette 8 in the reverse order of insertion. When the cassette is pulled out and the cassette is removed from the main body, the cassette is pushed to the guide groove position by pulling the tension spring 5 at the same time as the cassette is pushed away from the main body.

이상에서와 같이 본 고안은 카세트가 급지부 본체에 삽입되는 각도를 다르게 해주면서 스프링의 탄성력을 받도록하여 종이의 걸림을 완전히 배제할수 있고, 사용자가 카세트를 용이하게 착탈시킬수 있어 취급이 편리하며 또한 본 고안은 카세트가 구조적으로 급지부 몸체에 경사지게 고정되어야 할 경우에도 적당한 장치인 것이다.As described above, the present invention allows the cassette to be inserted into the feeder main body while receiving the elastic force of the spring, thereby completely eliminating paper jams, and allowing the user to easily detach and remove the cassette. It is a suitable device even when the cassette is structurally fixed to the paper feeder body.
