본 고안은 칼라 비디오 프린터의 인화지 급지장치에 관한 것으로, 특히 인화지가 1매씩 정확히 급지될 수 있고 급지대기 상태에서 인화지가 급지로울러에 걸쳐지는 현상을 방지할 수 있는 인화지 급지장치에 관한 것이다.The present invention relates to a photo paper feeding apparatus of a color video printer, and more particularly, to a photo paper feeding apparatus capable of accurately feeding one sheet of photo paper and preventing a photo paper from being fed over a feeding roller in a paper standby state.

종래에 일반적으로 사용되어온 칼라비디오 프린터의 급지부는 제4도와 같은 구조로 되어 있다.The paper feeding part of the color video printer generally used conventionally has a structure as shown in FIG.

즉, 인화지박스(1)내에 설치된 인화지 레버판(2)위에 인화지(13)가 얹혀져 있고 인화지박스의 하방에는 작동레버(3)가 설치되어 이 작동레버(3)의 회전에 따라 인화지 레버판(2)이 승강하도록 되어 있으며, 인화지박스의 상방에는 제1급지로울러(4)와 제2급지로울러(5) 및 2매급지방지로울러(6)가 설치되어 인화지를 상,하 급지가이드(7) (8)사이의 통로로 1매씩 이송시킬수 있게 되어 있다.That is, the photo paper 13 is placed on the photo paper lever plate 2 installed in the photo paper box 1, and an operating lever 3 is installed below the photo paper box, and the photo paper lever plate ( 2) is to be raised and lowered, the first paper feed roller (4), the second paper feed roller (5) and the two-sheet feed prevention roller (6) is installed above the photo paper box, the photo paper feed guide (7) It is possible to transfer one by one to the passage between (8).

또한 급지부의 하방에는 배지박스(14)와 배지로울러(15) (16) 및 배지가이드(17)가 설치되어 있다.Further, a discharge box 14, a discharge roller 15, 16, and a discharge guide 17 are provided below the paper feeder.

상기한 종래의 장치는 제4b도와 같이 인화지박스(1)에 인화지(13)가 얹혀진 상태에서 급지작동이 시작되면 제4a도와 같이 작동레버(3)가 도면상 반시계 방향의 회전을 함과 동시에 작동레버에 의해 인화지 레버판(2)과 인화지(13)가 상방으로 들어올려져 최상단의 인화지가 제1급지로울러(4)에 접속되고 제1급지로울러(4)와 제2급지로울러(5) 및 2매급지방지로울러(6)의 회전에 따라 상,하 급지가이드(7) (8)사이의 통로로 이송되며, 급지작동이 어느정도 진행되면 작동레버(3)가 원위치로 회전함과 동시에 인화지 레버판(2)로 원위치로 복귀되어 급지대기 상태가 된다.In the conventional apparatus, when the paper feeding operation is started with the photo paper 13 placed on the photo paper box 1 as shown in FIG. 4B, the operating lever 3 rotates in the counterclockwise direction as shown in FIG. 4A. Photo paper lever plate (2) and photo paper (13) are lifted upward by the operation lever, and the uppermost photo paper is connected to the first paper feed roller (4), and the first paper feed roller (4) and the second paper feed roller (5) and It is transferred to the passage between the upper and lower feeding guides (7) and (8) according to the rotation of the two-sheet feeding prevention roller (6), and when the feeding operation is progressed to some extent, the operating lever (3) rotates to its original position and the photo paper lever The plate 2 is returned to its original position, and the paper is waiting for feeding.

그러나 상기한 종래의 장치는 급지시 인화지(13)와 인화지레버판(2)이 작동레버(3)에 의해 경사방향으로 들러올려지면서 제1급지로울러(4)에 단순 접촉하는 구조이기 때문에 제4a도와 같이 인화지의 선단부가 제2급지로울러(5)의 상방으로 올라가 급지가 제대로 이루어지지 않는 경우가 있으며, 또한 1매의 인화지가 급지된후 인화지와 인화지 레버판(2)이 원위치로 복귀할 때 제4b도와 같이 최상단의 인화지가 제2급지로울러(5)와 2매급지방지로울러(6)사이에 걸쳐지거나 연속적으로 급지가 되는 등의 문제점이 있다.However, the above-described conventional apparatus has a structure in which the photo paper 13 and the photo paper lever plate 2 are simply contacted with the first paper feed roller 4 while being lifted in the inclined direction by the operating lever 3 during feeding. As shown in the drawing, the leading edge of the photo paper rises above the second paper feed roller 5, and the paper does not feed properly. Also, when the photo paper and the photo paper lever plate 2 return to their original positions after one sheet of paper is fed. As shown in FIG. 4B, there is a problem that the uppermost photo paper is interposed between the second paper feed roller 5 and the two sheet feed prevention roller 6 or continuously fed.

즉, 종래의 장치는 급지시 인화지의 선단부를 제2급지로울러(5)와 2매급지방지로울러(6)사이로 안내하는 적절한 장치가 없기 때문에 최초 급지 작동이 잘 이루어지지 않거나 또는 2매의 인화지가 급지되는 경우가 자주 발생하게 되는 문제점이 있었던 것이다.That is, in the conventional apparatus, since there is no suitable device for guiding the leading edge of the photo paper between the second paper feed roller 5 and the two paper feed prevention roller 6 when the paper is fed, the first paper feed operation does not work well or the two paper papers do not work well. There was a problem that often occurs when feeding.

본 고안은 제1급지로울러 부분에 인화지를 적절한 압력으로 눌러주면서 제2급지로울러 방향으로 안내하여주는 안전레버를 설치하여 인화지가 1매씩 정확하게 급지될 수 있도록 한것인바, 이를 첨부된 도면 제1도 내지 제3도를 참조하여 더욱 상세하게 설명하면 다음과 같다.The present invention is to install a safety lever to guide the direction of the second feed roller while pressing the photo paper in the first feed roller portion at an appropriate pressure so that the photo paper can be fed accurately one by one, attached to Figure 1 More detailed description with reference to Figure 3 as follows.

첨부도면 제1도는 본 고안 장치를 나타낸 측면도로서, 인화지박스(1), 인화지 레버판(2), 작동레버(3), 제1급지로울러(4), 제2급지로울러(5), 2매급지방지로울러(6), 상, 하급지가이드(7) (8)의 구조는 종래장치와 동일하게 되어 있으며, 제1급지로울러 (4)부분에 본 고안의 요지인 안전레버(9)가 설치되어 있다.1 is a side view showing the device of the present invention, a photo paper box 1, a photo paper lever plate 2, an operation lever 3, a first paper feed roller 4, a second paper feed roller 5, and two sheets. The feeding prevention roller (6), the upper and lower feed guides (7) and (8) have the same structure as the conventional apparatus, and the safety lever (9), which is the subject of the present invention, is installed in the first feeding roller (4). It is.

안전레버 (9)는 제2도 내지 제3도와 같이 대략 ㄷ자형으로 형성되어 있고 양측에는 힌지축(9a)과 피난홈(9b)이 형성되어 있으며, 이 안전레버(9)는 힌지축(9a)을 중심으로 회전이 가능하도록 상면판(12)에 결합되어 있다.The safety lever 9 is formed in an approximately c-shape as shown in FIGS. 2 to 3 and has hinge shafts 9a and evacuation grooves 9b formed on both sides thereof, and the safety levers 9 are hinge shafts 9a. It is coupled to the upper surface plate 12 so as to be able to rotate about the center.

또한 힌지축(9a)에는 토션스프링(10)이 설치되어 안전레버(9)가 항상 하방으로 회전하려는 힘을 받게되며, 안전레버(9)의 회전범위는 스토퍼(11)에 의해 제한된다.In addition, the hinge shaft 9a is provided with a torsion spring 10 so that the safety lever 9 is always forced to rotate downward, and the rotation range of the safety lever 9 is limited by the stopper 11.

피난홈(9b)은 안전레버(9)의 회전시 제1급지로울러(4) 샤프트와의 간섭을 일으키지 않도록 하기위한 것이다.The evacuation groove 9b is for preventing the interference with the first feed roller 4 shaft during the rotation of the safety lever 9.

이와같이 된 본 고안 장치의 작용효과를 설명한다.The effect of the device according to the present invention is explained.

첨부도면 제1b도는 급지대기 상태를 나타낸 도면으로서, 인화지(13)와 인화지 레버판(2)은 하강된 위치에 있고 안전레버(9)는 토션스프링(10)의 힘에 의해 스토퍼(11)에 걸리때까지 도면상 반시계 방향으로 회전하여 있다.1B is a view showing a state of waiting for feeding, the photo paper 13 and the photo paper lever plate 2 are in the lowered position, and the safety lever 9 is connected to the stopper 11 by the force of the torsion spring 10. FIG. It is rotated counterclockwise on the drawing until it is caught.

이러한 상태에서 급지작동이 시작되면 제1a도와 같이 작동레버(3)가 도면상 반시계 방향의 회전을 함과 동시에 인화지 레버판(2)과 인화지(13)가 상방으로 들어올려저 제1급지로울러(4)와 접촉하게 되고 제1급지로울러(4)의 회전 이송력에 의해 최상단의 인화지가 제2급지로울러(5)방향으로 이송되는데, 이렇게 인화지 레버판(2)과 인화지(13)가 들어올려진 상태에서는 안전레버(9)의 저면이 인화지에 접속되어 인화지가 토션스프링(10)에 의해 압력을 받게되므로 인화지의 선단부는 상방으로 들어올려지지 않고 제2급지로울러(5)와 2매급지방지로울러(6)사이로 정확하게 들어간다.When the paper feed operation starts in this state, as shown in FIG. 1A, the operation lever 3 rotates counterclockwise in the drawing and at the same time, the photo paper lever plate 2 and the photo paper 13 are lifted upwards to lower the first paper feed roller. (4) is brought into contact with the uppermost photo paper in the direction of the second paper feed roller (5) by the rotational feed force of the first paper feed roller (4), so that the photo paper lever plate (2) and photo paper (13) In the lowered state, the bottom of the safety lever 9 is connected to the photo paper, and the photo paper is pressurized by the torsion spring 10. Therefore, the tip of the photo paper is not lifted upward, and the second paper feed roller 5 and the second sheet feeding prevention are prevented. Enter correctly between the rollers (6).

또 1개의 인화지가 급지된 후 작동레버(3)와 인화지 레버판(2)이 원위치로 복귀할때에는 제1b도와 같이 안전레버(9)가 토션스프링(10)의 힘에 의해 반시계 방향의 회전을 하게 되므로 인화지가 로울러 사이에 걸려있는 경우에도 안전레버(9)의 회전력에 의해 걸려있는 인화지가 인화지 레버판(2)위로 떨어지게 된다.When the operation lever 3 and the photo paper lever plate 2 return to their original positions after one photo paper is fed, the safety lever 9 rotates counterclockwise by the force of the torsion spring 10 as shown in FIG. Therefore, even when the photo paper is caught between the rollers, the photo paper hanging by the rotational force of the safety lever 9 falls on the photo paper lever plate 2.

따라서 2매의 인화지가 급지될 우려가 없게되는 것이다.Therefore, there is no fear of feeding two sheets of photo paper.

이상에서와 같이 본 고안은 제1급지로울러 부분에 인화지를 눌러주는 역할의 안전레버를 설치하여 급지작동시 인화지를 1매씩 원활하게 급지할 수 있게 되고 급지후 인화지가 로울러 사이에 걸리거나 2매가 급지되는것을 방지할 수 있게 되는 효과가 있다.As described above, the present invention installs a safety lever that presses the photo paper in the first feed roller portion so that the photo paper can be smoothly fed one by one during the feeding operation, and the photo paper is caught between the rollers or two sheets are fed after feeding. There is an effect that can be prevented.
