본 고안은 노랑색(Y), 주황색(M), 청색(C), 3색을 순차로 승화시켜 비디오 신호를 프린팅하는 비디오 프린터 장치의 기록위치 제어용 센서의 취부장치에 관한 것이다.The present invention relates to a mounting apparatus of a recording position control sensor of a video printer device which prints a video signal by sequentially sublimating yellow (Y), orange (M), blue (C) and three colors.

통상 비디오 신호를 기록지에 기록하는 비디오 프린터에 있어서 계조 표현이 자유롭고, 모든 색깔 기록이 가능한 Y, M, C 3색을 순차 승화시키는 승화형 열전사 방식이 제안되어 있다.In general, a sublimation type thermal transfer method that sequentially sublimates Y, M, and C colors capable of recording all colors in a video printer for recording a video signal on a recording sheet is free.

이를 첨부된 도면에 의해 설명하면 검정색(B), 노랑색(Y), 주황색(M), 청색(C), 4색의 승화 염료가 면순차되어 구성되어 있는 잉크리본(2)과 감열기록지(3)와 드럼(4)과 등속도로 진행한다.Referring to the accompanying drawings, the ink ribbon (2) and the thermal recording paper (3) composed of sublimation dyes of black (B), yellow (Y), orange (M), blue (C), and four colors in a plane order are described. ) And the drum (4) at a constant speed.

이러한 회전 운동을 할때 감열기록 헤드(1)는 발열을 하여 발열량에 의해 잉크리본(2)의 Y, M, C 각 잉크의 양에 의해 합성색이 달라져서 모든 색깔의 프린팅이 가능해지는 것이다.During this rotational motion, the thermal recording head 1 generates heat, and the composite color is changed depending on the amount of Y, M, and C inks of the ink ribbon 2 depending on the amount of heat generated, so that printing of all colors is possible.

이를 좀더 상세히 센서(7)를 드럼(4)의 중심을 향하게 배치하고 센서(7)은 열승화기록지의 끝단을 감지하여 기록헤드(1)의 발열을 시작시키고 센서(7)와 감열기록 헤드(1)의 위치는 D의 거리를 유지한 상태에서 고정되어 있으며 드럼(4)과 열승화형기록지(3) 앞끝단을 감지했을때 열승화형기록(3)의 기록면에 기록을 시작하게 되므로 열승화형기록지(3)의 초기 위치는 D의 거리만큼 여백을 형성한다.In more detail, the sensor 7 is disposed toward the center of the drum 4, and the sensor 7 detects the end of the thermal sublimation recording paper to start the heating of the recording head 1, and the sensor 7 and the thermal recording head ( The position of 1) is fixed while maintaining the distance of D. When the front end of the drum 4 and the thermal sublimation recording paper 3 is detected, the recording starts on the recording surface of the thermal sublimation recording 3, The initial position of the sublimation recording paper 3 forms a margin by the distance of D.

이상과 같이 연속 인쇄를 위해 드럼(4)과 감열기록지(3)는 3회전을 해야 하며 감열기록 헤드(1) Y, M, C 각 색깔에 대해 다른 양의 발열을 해야 하므로 세번의 발열을 하고 잉크리본(2)은 열승화형기록지(3)위를 Y, M, C 각각 한번씩 거쳐가야 한다.As described above, the drum 4 and the thermal recording paper 3 must be rotated three times for continuous printing. The thermal recording head 1 needs to generate a different amount of heat for each color of Y, M, and C. The ink ribbon 2 must pass through the thermal sublimation recording paper 3 once in each of Y, M, and C.

따라서 잉크리본(2)은 리본공급 릴(6)에 감겨있다가 드럼(4)에 의해 회전하여 리본 권취릴(5)에 감기며 Y, M, C 각 색깔의 길이는 드럼(4)원주길이와 같다.Therefore, the ink ribbon 2 is wound on the ribbon supply reel 6, rotated by the drum 4, and wound on the ribbon winding reel 5, and the length of each of Y, M, and C colors is the length of the drum 4 circumference. Same as

상기와 같은 승화형 열전사 방식의 프린터는 열승화형 기록지(3)를 3회전시켜서 Y, M, C 를 순차 흡착하므로 첫번째, 두번째, 세번째의 초기 기록위치를 정확히 맞추어야 하고 그렇지 않을 경우 Y, M, C 인쇄역이 어긋남으로 인해 화질이 저하되고 정확한 색깔의 합성이 불가능하며 기록지에 대한 화면의 이상적인 배치가 되지 않고 전,후 밀려서 기록되고 화면의 전, 후에는 어긋난 양만큼의 Y, M, C 색깔의 띠가 생긴다.The printer of the sublimation type thermal transfer method rotates the thermal sublimation type recording paper 3 three times to sequentially adsorb Y, M, and C. Therefore, the first, second, and third initial recording positions must be exactly aligned. The image quality is deteriorated due to the misalignment of the printing area, the color is not synthesized correctly, and the screen is pushed back and forth without being the ideal layout of the recording paper, and the amount of Y, M, C is shifted before and after the screen. A colored strip is created.

그러므로 열승화형 기록지(3)의 초기위치를 센서가 정확하게 감지할 수 있어야 한다.Therefore, the sensor should be able to accurately detect the initial position of the thermal sublimation recording paper 3.

이와같은 센서를 부착하기 위한 구성을 종래에는 제 4 도와 같이 구성하였다. 즉 센서(7)은 평상시 검은색의 드럼(4)을 감지하고 있다가 흰색의 감열기록지(3)가 들어오면 감열기록지(3) 끝단에서 감지를 한 다음 발열부(8)가 발열을 시작하며, 이런한 동작을 Y, M, C 에 대해 각가 한번씩 한다.The structure for attaching such a sensor was conventionally comprised as the 4th degree. That is, the sensor 7 normally detects the black drum 4, and when the white thermal recording paper 3 comes in, the sensor 7 detects at the end of the thermal recording paper 3, and then the heating unit 8 starts to generate heat. , Do this once for Y, M, and C.

이때 센서(7)의 끝단의 열승화기록지(3)의 표면과는 (H)의 양만큼 이격되어 있고 감지역(9)은 개방되어 있으므로, 외부의 빛등에 의해 정확한 감지가 어려운 문제점이 있으면 열승화형 기록지가 열변형등에 의하여 변형되었을 경우 센서(7)와 기록지와의 거리(H)의 변형이 발생하므로 정확한 센싱을 할 수 없으므로 센싱 감지대역 F만큼 오차가 발생한다.At this time, since the surface of the thermal sublimation recording paper 3 at the end of the sensor 7 is spaced apart by the amount of (H) and the detection zone 9 is open, if there is a problem that it is difficult to accurately detect by external light, When the sublimation type recording paper is deformed due to thermal deformation or the like, a deformation of the distance H between the sensor 7 and the recording paper occurs, so that accurate sensing cannot be performed, and thus an error occurs as much as the sensing detection band F.

본 고안을 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서 센서의 취부구조를 개선하여 추기 기록위치를 감지하는데 생기는 오차를 없게하고 화질의 향상을 기하고자 하는데 목적이 있는 것이다.The present invention has been made in order to solve the above problems, and is intended to improve the image quality by eliminating an error in detecting the recording position by improving the mounting structure of the sensor.

상기와 같은 목적을 수행하기 위한 본 고안의 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment of the present invention for carrying out the above object will be described in detail with reference to the accompanying drawings.

제 5 도를 참조하여 본 고안의 구성을 설명하면, 센서(15)를 취부하기 위한 센서홀더(12)를 열승화형기록지(13)의 두께만큼 이격시켜 플라텐드럼(4)과 이격하여 설치하되 열승화형 기록지(13)가 인입되는 측의 끝단 하측에는 경사진 용지안내면(16)을 형성하고, 센서(15)의 하측에는 밑면이 좁아지도록 경사면(14)을 형성하여 열승화형 기록지(13)가 센서 홀더의 개구부를 완전히 가렸을 경우 센싱되어 감열헤드(10)의 발열부(11)가 발열을 시작하도록 하여서 된 것이다.Referring to FIG. 5, the configuration of the present invention will be described. The sensor holder 12 for mounting the sensor 15 is spaced apart from the platen drum 4 by the thickness of the thermal sublimation recording paper 13. However, the inclined paper guide surface 16 is formed on the lower side of the end of the side on which the thermal sublimation recording paper 13 is drawn, and the inclined surface 14 is formed on the lower side of the sensor 15 to form a thermal sublimation recording paper ( When 13) completely covers the opening of the sensor holder, it is sensed so that the heat generating portion 11 of the thermal head 10 starts to generate heat.

이와 같이 구성된 본 고안의 작용효과는 감열기록헤드(10)의 발열부(11)와 센서(15)와의 거리(I)를 열승화형기록지(13)의 여백만큼 일치하도록 고정 배차하고 플라텐드럼(4)이 회전하면 프라텐드럼(4)과 면접촉되어진 열승화형기록지(13)가 센서홀더(12)측으로 인입된다. 이때 열승화형기록지(13)는 센서홀더(12)의 끝단에 형성된 경사진 안내면(16)에 안내되면서 플라텐드럼(4)과 센서홀더(12)사이로 인입되면 센서(15)가 용지의 인입을 감지하게 되어 감열기록헤드(10)를 구동하여 발열토록 한다.The working effect of the present invention configured as described above is fixedly arranged to match the distance (I) between the heat generating portion 11 and the sensor 15 of the thermal recording head 10 by the margin of the thermal sublimation recording paper 13, and the platen drum. When (4) rotates, the thermal sublimation recording paper 13 which is in surface contact with the platen 4 is drawn to the sensor holder 12 side. At this time, the thermal sublimation recording paper 13 is guided to the inclined guide surface 16 formed at the end of the sensor holder 12 while being pulled in between the platen drum 4 and the sensor holder 12. To sense heat and drive the thermal recording head 10 to generate heat.

이때 센서홀더(12)의 하측단과 플라텐드럼(4)과의 거리가 용지의 두께와 같으므로 기록용지(13)는 플라텐드럼(4)에 밀착되어 진행하게 되며 센서(15)는 최초에 플라텐드럼(4)의 검은 면을 감지하고 있던중 용지에 의해서 개구부가 완전히 막혔을때 부터 발열부(11)가 발열하도록 한다.At this time, since the distance between the lower end of the sensor holder 12 and the platen drum 4 is equal to the thickness of the paper, the recording paper 13 is brought into close contact with the platen drum 4 and the sensor 15 is initially The heat generating part 11 generates heat when the black surface of the platen drum 4 is detected and the opening is completely blocked by the paper.

따라서 감열기록지(13)는 화살표 방향으로 움직이며 센싱을 위한 개구부는 센서(15)의 최소 감지폭(G)이므로 임의의 한 점인(g)까지 전진해도 센싱이 되지않고 최소 감지폭(G)을 기록지가 완전히 막는 순간 정확한 센싱을 할 수 있는 것이다.Therefore, the thermal recording paper 13 moves in the direction of the arrow, and the opening for sensing is the minimum sensing width G of the sensor 15, so even if it advances to any one point (g), the sensing paper G does not sense the minimum sensing width G. Accurate sensing is possible at the moment the recording sheet is completely blocked.

상기와 같은 본 고안에 의하면 센서의 감지폭의 흔들림이나 크기, 센서와 감열기록지와의 거리의 변화, 센서에 대한 외란등으로 기인한 초기 기록위치의 오차를 없앨 수 있으므로 기록지가 3회전하면서 각각 Y, M, C 기록을 순차적으로 수행하더라도 정확한 초기 기록위치의 제어가 가능해진다.According to the present invention as described above, it is possible to eliminate the error of the initial recording position caused by the shaking width or size of the sensor, the change of the distance between the sensor and the thermal recording paper, and the disturbance of the sensor. Even if M, C recording is performed sequentially, accurate initial recording position can be controlled.
