본 고안은 레이저 빔 프린터의 급지장치에 관한 것으로 특히 카세트 장착시 종이가 구겨지지 않으면서 급지로울러와 종이가 밀착되도록 한 레이저 빔 프린터의 급지장치에 관한 것이다.The present invention relates to a paper feeding device for a laser beam printer, and more particularly, to a paper feeding device for a laser beam printer to be in close contact with a paper feed roller while the cassette is not wrinkled.
종래에는 제1도에서 보는 바와같이 카세트(40)와 서포트(41)사이에 스프링(36)을 탄력 설치하여 서포트(41)의 상측에 종이(46)를 올려놓은 다음 카세트(40)를 베이스(31)의 카세트 급지부(35)에 밀어 넣었던 것이다.Conventionally, as shown in FIG. 1, a spring 36 is elastically installed between the cassette 40 and the support 41 to place the paper 46 on the upper side of the support 41, and then the cassette 40 is mounted on the base ( 31 is pushed into the cassette feeder 35.
따라서 이와같은 장치는 카세트장착기 스프링(36)의 탄성력에 의해 종이(46)의 선단부가 급지로울러(47)에 걸려 구겨짐으로서 잼(Jom) 발생의 원인이되고 이를 방지하기 위해서는 카세트 삽입시 사용자가 카세트(40)를 눌러 일정한 각도로 기울여 경사진 상태로 장착시키면서 수평상태로 놓아야 하는 불편함이 있었다.Therefore, in such a device, the tip of the paper 46 is creased by the feeding roller 47 by the elastic force of the cassette mounter spring 36, which causes jams and prevents the user from inserting the cassette. There was an inconvenience to put the horizontal state while pressing inclined at a certain angle (40) to be mounted in an inclined state.
본 고안은 이와같은 문제점을 해결하기 위하여 사용자가 카세트를 장착하면 급지로울러와 종이가 밀착되도록 안출한 것으로 첨부된 도면에 의거 설명하면 다음과 같다.The present invention is to solve the problems described above, when the user is equipped with a cassette, the paper feed roller and the paper is designed to be in close contact with the accompanying drawings as follows.
제2도의 분해 사시도와 제3도의 조립 정단면도에서 보는 바와 같이 베이스(1)와 측면 프레임(2), (3) 그리고 톱플레이(4)로 형성된 카세트 끼움부(5)에 있어서 일측프레임(2)에 뚫려있는 구멍(2c)으로 하단에 평면부(6a)가 형성된 고정축(6)을 끼워넣어 일측을 지지대(7)의 구멍(7a)에 끼워넣고 외부로 돌출된 일측에는 구멍(8a)를 형성한 리미터(Limiter)(8)를 고정, 설치하며 평면부(6a)에는 후단을 직각으로 절곡시킨 브라겟트(9)의 선단부에 로울러(10)를 부착설치핀(11)을 고정시킨다.As shown in the exploded perspective view of FIG. 2 and the assembled front sectional view of FIG. 3, one side frame (2) is provided in the cassette fitting portion (5) formed of the base (1), the side frames (2), (3) and the top play (4). A fixed shaft 6 having a flat portion 6a formed at the lower end thereof through a hole 2c drilled in the bottom), and one side is inserted into the hole 7a of the support 7 and a hole 8a is formed at one side that protrudes outward. The limiter (8) is formed and fixed, and the roller (10) is fixed to the front end of the bracket (9), the rear end of which is bent at right angles to the flat portion (6a).
전면에 원호적으로 가이드편(12a)을 형성한 가이드편(12)에는 일측상단에 형성한 반원형의 지지축(12a)을 프레임(12)의 상측구멍(12b)에 끼워 선단을 외부로 돌출시킨 다음 일측에 구멍(13a)이 뚫린 스프링 브라겟트(13)를 부착설치하여 이 구멍(13a)과 리미터(8)의 구멍(8a)을 인장스프링(14)으로 연결하고, 하단에 형성한 돌기(12c)를 프레임(2)의 둥근 삽입홈(2b)에 끼워 회전운동 가능하게 설치하며 톱 플레이트(4)의 하단에형으로 절곡(折曲)된 고정 브라겟트(15)를 스크류(24), (25)로 조임 연결하여 양측에 뚫려 있는 구멍(15a), (l5b)으로 급지로울러(17)를 부착설치한 샤프트(16)를 끼워넣은 후 샤프트(16)의 일측에 측면 프레임(3)의 외부로 돌출시켜 구동기어(9)와 맞물리도록 이송기어(18)를 부착설치한다.In the guide piece 12 having the guide piece 12a circularly formed on the front surface, a semicircular support shaft 12a formed at one upper end was inserted into the upper hole 12b of the frame 12 to protrude the tip outward. Next, attaching and installing a spring bracket 13 having a hole 13a drilled at one side thereof, connecting the hole 13a and the hole 8a of the limiter 8 with a tension spring 14, 12c) is inserted into the round insertion groove 2b of the frame 2 so as to be rotatable and installed at the bottom of the top plate 4. Shaft with fastening bracket (15) bent into a shape by screw (24), (25) and attaching feed roller (17) through holes (15a) and (l5b) drilled on both sides. After inserting (16), the transfer gear 18 is attached to one side of the shaft 16 to protrude to the outside of the side frame (3) to engage the drive gear (9).
또한 카세트(20)에는 저면에 로울러(10)가 끼워질 수 있도록 장공(20a)을 형성하고 후면 양측으로 구멍(20c), (20d)을 뚫어 서포트(21)의 양측돌기(21a), (21b)를 끼워넣고 선단부의 높이를 낮게 형성하여 급지로울러(17)가 걸리지 않게 한다.In addition, the cassette 20 is formed with a long hole 20a so that the roller 10 can be inserted into the bottom surface, and holes 20c and 20d are drilled to both sides of the rear side, so that the protrusions 21a and 21b of the support 21 are supported. ) And the height of the tip is made low so that the feed roller 17 is not caught.
상기의 구멍에 따른 동작을 설명하면 다음과 같다.The operation according to the above-described holes is as follows.
제4도와 같이 카세트(20)를 끼움부(5)에 설치하지 않았을 때에 가이드편(12)의 돌기(12c)가 아래로 내려와 있으나 제5도와 갈이 카세트(20)를 끼워넣고 카세트(20)의 돌기(20d)가 가이드편(12)의 가이드편(12a)과 접촉하면서 가이드편(12)을 밀게되어 가이드편(12)이 측면 프레임(2)의 삽입홈(2b)을 따라 상측방향으로 회전한다.When the cassette 20 is not installed in the fitting portion 5 as shown in FIG. 4, the projection 12c of the guide piece 12 is lowered, but the cassette 20 is inserted into the cassette 20 in FIG. The projection 20d pushes the guide piece 12 while contacting the guide piece 12a of the guide piece 12 so that the guide piece 12 moves upward along the insertion groove 2b of the side frame 2. Rotate
이때 가이드편(12)의 지지축(12b)이 회전함에 따라 여기에 고정되있는 스프링 브라겟트(13)도 회전하여 인장스프링(14)으로 연결되어 있는 리미터(8)를 상측방향으로 회전시키게 된다.At this time, as the support shaft 12b of the guide piece 12 rotates, the spring bracket 13 fixed thereto is also rotated to rotate the limiter 8 connected to the tension spring 14 upward. .
따라서 카세트(20)의 장공(20a)내에 삽입된 로울러(10)가 상측으로 회전운동하면서 서포트(21)의 하단을 밀어 올림으로서 도시하지 않은 종이가 상측의 급지로울러(17) 저면에 틈새 없이 접촉된다.Therefore, as the roller 10 inserted in the long hole 20a of the cassette 20 rotates upward, the lower part of the support 21 is pushed up so that the paper (not shown) contacts the bottom of the upper feed roller 17 without any gap. do.
이와같이 본 고안은 카세트(20)를 장착하면 인장스프링(14)의 힘에 의해 로울러(10)가 서포트(21)를 밀어 올림으로서 종이(26)가 구겨지지 않으면서 급지로울러(17)와 항상 밀착되어 잼(Jom)현상을 방지할 수 있고 카세트(20)를 기울여서 끼워넣을 필요가 없기 때문에 카세트 취급이 매우 편리한 것이다.Thus, when the cassette 20 is mounted, the roller 10 pushes up the support 21 by the force of the tension spring 14 so that the paper 26 does not be wrinkled and is always in close contact with the paper feed roller 17. Since the jam can be prevented and the cassette 20 does not need to be tilted into the cassette, handling of the cassette is very convenient.
