본 고안은 전자식 프린터등에 사열하는 2열 데이지휠의 승강장치에 관한 것으로, 특히 휠축에 중심부가 유착된 연결레버의 일측단을 휠 구동모우터의 회전축에 유착하고, 그의 타측단에는 접촉핀을 돌설시키며, 스텝모우터의 회전축에는 2개의 다른 정점을 가지는 편심캠을 축설하여 접촉핀의 하부에 설치함으로써 편심캠의 회전에 의해 데이지횔이 상. 중. 하로 승강자재되도록 한 2열 데이지휠의 승강장치에 관한 것이다.The present invention relates to a lifting device of a two-row daisy-wheel, which is arranged in an electronic printer. In particular, one end of the connecting lever in which the center is attached to the wheel shaft is attached to the rotating shaft of the wheel driving motor, and the contact pin is protruded at the other end thereof. On the axis of rotation of the step motor, an eccentric cam having two different vertices is installed and installed at the bottom of the contact pin. medium. It relates to a lifting device of a two-row daisy-wheel which is allowed to lift up and down.
종래의 데이지휠 승강장치에 있어서는, 유니버설 조인트나 슬립조인트로 구동모우터와 데이지휠을 연결하여 데이지휠만 별도로 상·하 승강자재되도록 구성되어 있으나, 이는 조인트의 마모등으로 인하여 데이지휠의 글자선택위치에 오차를 가져오게 되어 글자가 삐뚤어지게 인자되는 문제점이 있었다. 이에 따라 스텝모우터를 사용하여 데이지휠이 상·하 승강되도록 고안된 여러가지의 상·하 구동장치가 있으나, 이들의 대부분은 스텝모우터가 회전할때 발생되는 구동오차로 인하여 인자품질에 나쁜 영향을 끼치게 될 뿐만 아니라, 사용자가 인자상태를 확인하기 위해서는 일일이 플래턴을 돌려보거나, 또는 고개를 숙여 비스듬히 보아야 하는 어려움이 있었다.In the conventional daisy wheel lifting device, the drive wheel and the daisy wheel are connected by universal joints or slip joints so that only the daisy wheel can be lifted up and down separately. There was a problem that the letters are printed skewed to bring the error in the position. Accordingly, there are various up and down driving devices designed to move the daisy wheel up and down using the step motor, but most of them have a bad effect on the print quality due to the driving error generated when the step motor rotates. Not only that, the user had to turn the platen one by one or check her face at an angle to check the printing status.
본 고안은 상기의 점을 감안하여, 스텝모우터의 회전축에 편심캠을 축설하고, 편심캠의 회전에 따라 승강자재되는 연결레버의 중앙부를 휠축에 유착시켜 데이지휠이 상·중·하로 승강자재되도록 함으로써, 스텝모우터의 약간의 구동오차에 의해서는 안자품질에 아무런 영향도 주지 않고, 또한 인자상태를 확인하기 용이하도록 안출한 것으로, 이하 첨부된 도면에 의하여 본 고안을 상세히 설명하면 다음과 같다.The present invention, in view of the above point, erected the eccentric cam on the rotating shaft of the step motor, and adheres the center portion of the connecting lever, which is the lifting material according to the rotation of the eccentric cam to the wheel shaft, the daisy wheel is lifted up, down, middle By doing so, a slight driving error of the step motor has no effect on the quality of the eye, and it is designed to make it easy to check the printing state. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. .
제1도 내지 제3도에 도시된 바와 같이, 휠구동모우터(1)의 회전축(1')에 축설된 구동기어(2)로 휠축(3)에 축설된 휠기어(4)를 회전시켜 데이지휠(5)을 회전시키고, 스텝모우터(6)로 데이지휠(5)이 상·하 이동자재되도록 한 2열 데이지휠의 승강장치에 있어서, 휠축(3)에 연결레버의 중앙부를 유착시키고, 그 연결레버(7)의 일측단은 휠구동모우터(1)의 회전축(1')에 유착시키며, 연결레버(7)의 타측단에는 접촉핀(7')을 돌설시키는 한편, 스텝모우터(6)의 회전축(6')에는 곡률반경이 각기 다른 3개의 정점(8a),(8b),(8c)을 갖는 편심캠을 축설하여 그 편심캠(8)을 접촉핀(7')의 하부에 설치하고 접촉핀(7')의 근처 적당위치에는 접촉핀(7')과 편심캠(8)이 적당한 압력으로 밀착되도록 인장스프링(9)을 설치하여 구성한 것으로, 미설명부호 10은 플래턴상의 인자장소이다.As shown in FIGS. 1 to 3, the wheel gear 4 installed on the wheel shaft 3 is rotated by the drive gear 2 arranged on the rotation shaft 1 ′ of the wheel driving motor 1. In the elevating device of a two-row daisy wheel in which the daisy wheel 5 is rotated and the daisy wheel 5 is moved up and down by the step motor 6, the center portion of the connecting lever is attached to the wheel shaft 3. One end of the connecting lever 7 is brought into contact with the rotating shaft 1 'of the wheel driving motor 1, and the other end of the connecting lever 7 is provided with a contact pin 7', while the step An eccentric cam having three vertices 8a, 8b, and 8c having different radii of curvature is formed in the rotation shaft 6 'of the motor 6, and the eccentric cam 8 is connected to the contact pin 7'. ) And a tension spring (9) is installed at a suitable position near the contact pin (7 ') so that the contact pin (7') and the eccentric cam (8) is in close contact with a suitable pressure, and Is the printing place on the platen.
이와 같이 구성된 본 고안은 데이지휠(5)의 내측열에 있는 자소를 인자하고저 할때에는 제1도에 도시된 바와 같이 적당한 구동신호를 스텝모우터(6)에 인가하여 스텝모우터(6)의 회전축(6')을 회전시켜서 편심캠(8)이 적당한 각도로 회전하면서, 접촉핀(7')을 상향으로 밀어 그 편심캠(8)의 곡률반경이 가장 큰 정점(8a)부위가 접촉핀(7')의 위치에 오게 하면, 연결레버(7)가 휠구동모우터(1)의 회전축(1')을 중심으로 적당히 상향이동되고, 이에 따라 데이지휠(5)이 상향이동되어 내측열 활자를 인자할 수 있는 위치에 도달하게 된다. 또한, 제2도에 도시된 바와 같이 데이지휠(5)의 외측열 활자를 인자할 경우에도 상기에서와 같이 편심캠(8)이 적당한 각도로 회전되어 중간길이의 곡률반경을 갖는 정점부위(8b)가 접촉핀(7')과 접촉되는 위치에 오게되면, 연결레버(7)가 중간부에 위치되므로 데이지휠(5)이 외측열활자를 인자하는 적당한 위치에 도달하게 된다. 그리고 일정시간동안 인자시키기 위한 입력신호가 없게 되면, 제3도에 도시된 바와 같이 편심캠(8)의 곡률반경이 가장 작은 정점(8c)부위가 접촉핀(7')에 접촉되게 편심캠(8)이 회전하게되어 연결레버(7)가 회전축(1')을 중심으로 하향이동되고, 데이지휠(5)이 하향이동되어 플래턴상의 인자위치가 노출되므로 인자상태를 확인하기가 용이하게 된다.The present invention configured as described above prints the element in the inner row of the daisy wheel 5 and, when it is reduced, applies a suitable driving signal to the step motor 6 as shown in FIG. As the eccentric cam 8 is rotated at an appropriate angle by rotating the rotation shaft 6 ', the contact pin 7' is pushed upwards so that the vertex 8a having the largest radius of curvature of the eccentric cam 8 is the contact pin. At the position of 7 ', the connecting lever 7 is appropriately moved about the rotational axis 1' of the wheel drive motor 1, and accordingly, the daisy wheel 5 is moved upward to move the inner row. You get to where you can print. In addition, as shown in FIG. 2, even when printing the outer column type of the daisy wheel 5, the eccentric cam 8 is rotated at an appropriate angle as described above, so that the vertex portion 8b having the curvature radius of the intermediate length is provided. ) Is brought into contact with the contact pin 7 ', the connecting lever 7 is located in the middle so that the daisy wheel 5 reaches an appropriate position for printing the outer heat print. And when there is no input signal for printing for a predetermined time, as shown in FIG. 3, the eccentric cam (8c) where the radius of curvature of the eccentric cam 8 is the smallest is in contact with the contact pin 7 '. 8) is rotated so that the connecting lever 7 is moved downward about the rotation axis (1 '), and the daisy wheel (5) is moved downward to expose the printing position on the platen, it is easy to check the printing state .
이상에서 설명한 바와 같이 본 고안은 각기 곡률반경이 다른 3개의 정점(8a),(8b),(8c)을 갖는 편심캠(8)의 회전에 따라 데이지휠(5)이 상·중·하로 이동되므로 인자상태를 확인하기가 용이할뿐만 아니라 데이지휠(5)이 상·중·하로 이동되어 정지상태를 유지할 경우에는 편심캠(8)의 각 정점(8a),(8b),(8c)이 적당한 각도로 같은 반경을 가지고 있으므로 스텝모우터(6)에 약간의 구동오차가 생기더라도 데이지휠(5)은 정확하게 이동되어 인자품질에 아무런 영향도 미치지 않게 되는 효과가 있다.As described above, according to the present invention, the daisy wheel 5 moves up, middle, and down according to the rotation of the eccentric cam 8 having three vertices 8a, 8b, and 8c having different curvature radii. Therefore, not only is it easy to check the printing state, but also when the daisy wheel 5 is moved up, middle, and down to maintain a stationary state, each vertex 8a, 8b, 8c of the eccentric cam 8 Since it has the same radius at an appropriate angle, even if a slight driving error occurs in the step motor 6, the daisy wheel 5 is accurately moved, which has no effect on the printing quality.
