When the pickup plate 52 is advanced, the pickup protrusion 32a passes through the inclined rail 56c from the upper rail 56a and is located on the lower rail 56b. Accordingly, the pickup lever 32 rotates around the shaft 31 of the idle gear, and the other end of the pickup lever 32 is raised by the lever principle. Therefore, the pickup roller 20 having the shaft 21 connected to the other end of the pickup lever 32 is in an UP state. In this way, when the pickup roller 20 is in the up state, it is not in close contact with the upper portion of the recording medium stored in the storage unit 10, so that the recording medium cannot be supplied forward (see FIG. 6).
도 7 내지 도 9를 참조하면, 피드 롤러(70)의 축을 중심으로 회동하는 플래튼 플레이트(60)가 구비된다. 즉, 플래튼 플레이트(60)를 피드 롤러(70)의 축에 힌지결합하도록 플래튼 플레이트(60)의 일측에는 상기 피드 롤러(70)의 축이 관통하는 힌지홀(61)이 형성되고, 타측에는 플래튼 롤러(63)가 지지된다. Referring to FIGS. 7 to 9, a platen plate 60 is rotated around an axis of the feed roller 70. That is, a hinge hole 61 through which the axis of the feed roller 70 penetrates is formed at one side of the platen plate 60 so as to hinge the platen plate 60 to the axis of the feed roller 70. On the side, a platen roller 63 is supported.
또한 일단은 피드 롤러(70)의 축에 연결되고, 타단은 상기 플래튼 롤러(63)의 축에 연결되는 한 쌍의 지지판(도 10의 '73'참조)이 구비된다. 즉, 상기 플래튼 롤러(63)는 상기 플래튼 플레이트(60)의 상부에 고정되어 설치되는 것이 아니라 상기 한 쌍의 지지판(73)에 의해 피드 롤러(70)의 축을 중심으로 회전할 수 있도록 유동적으로 설치되는 것이다. In addition, one end is connected to the axis of the feed roller 70, and the other end is provided with a pair of support plates (see '73' in FIG. 10) connected to the axis of the platen roller 63. That is, the platen roller 63 is not fixed and installed on the upper platen plate 60, but is movable so as to rotate about the axis of the feed roller 70 by the pair of support plates 73. Is to be installed.
또한 상기 플래튼 플레이트(60)의 양측에는 한 쌍의 제1스프링(S1)이 구비되고, 상기 제1스프링은 플래튼 롤러(63)의 양축을 탄성적으로 지지한다. In addition, a pair of first springs S1 are provided on both sides of the platen plate 60, and the first springs elastically support both axes of the platen roller 63.
따라서 상기 플래튼 롤러(63)는 상기 플래튼 플레이트(60)의 상부에 구비되지만, 제1스프링(S1)에 의해 상하방향으로 탄성적으로 움직임이 가능하다. Therefore, the platen roller 63 is provided on the upper portion of the platen plate 60, but is elastically movable in the vertical direction by the first spring S1.
인쇄시 플래튼 플레이트(60)를 회전하여 헤드(40)의 하부에 플래튼 롤러(63)를 기록매체의 두께보다 작은 갭을 형성하면서 밀착시키고, 기록매체가 상기 갭을 통해 진입할 때 플래튼 플레이트(60)는 고정되지만, 플래튼 롤러(63)가 기록매체의 두께에 대응하여 하측으로 움직일 수 있도록 하기 위함이다. 이 때 플래튼 롤러(63)와 헤드(40) 사이에 기록매체가 위치된 상태에서 상기 제1스프링(S1)이 플래튼 롤러(63)를 헤드 방향으로 탄성적으로 가압하여 기록매체와 잉크리본을 헤드에 밀착시켜 화상의 품질이 향상되는 것이다. When printing, the platen plate 60 is rotated to close the platen roller 63 to the lower portion of the head 40 while forming a gap smaller than the thickness of the recording medium, and when the recording medium enters through the gap, the platen The plate 60 is fixed, but it is to enable the platen roller 63 to move downward in response to the thickness of the recording medium. At this time, in the state where the recording medium is positioned between the platen roller 63 and the head 40, the first spring S1 elastically presses the platen roller 63 in the head direction, thereby recording medium and ink ribbon The quality of the image is improved by sticking to the head.
상기 슬라이드 플레이트(50)의 선단에는 플래튼 플레이트(60)의 하부로 진입하여 플래튼 플레이트를 피드 롤러(70)의 축을 중심으로 회전하여 상승시키는 리프터(51)가 구비된다. 상기 리프터(51)의 선단은 상기 플래튼 플레이트(60)의 하부로 진입하는 것을 용이하도록 경사면(51a)이 형성된다. 또한 상기 플래튼 플레이트(60)의 저면에는 상기 리프터(51)가 접하는 돌출부(64)가 형성되는데, 본 실시예에서 상기 돌출부(64)는 라운드지게 형성되어 있다. 또한 상기 돌출부는 라운드 대신 경사지게 형성되는 것도 가능하다. The front end of the slide plate 50 is provided with a lifter 51 which enters the lower portion of the platen plate 60 and rotates the platen plate to rotate around the axis of the feed roller 70. The front end of the lifter 51 is formed with an inclined surface 51a to facilitate entry into the lower portion of the platen plate 60. In addition, on the bottom surface of the platen plate 60, a protrusion 64 that the lifter 51 abuts is formed. In this embodiment, the protrusion 64 is formed to be round. Also, it is possible that the protrusion is formed to be inclined instead of round.
또한 일단이 상기 플래튼 플레이트(60)에 연결된 제2스프링(S2)이 구비된다. 상기 제2스프링은 본 실시예에서 토션스프링으로 구성되며 타단은 프레임에 위치된다. In addition, a second spring S2 having one end connected to the platen plate 60 is provided. The second spring is composed of a torsion spring in this embodiment, and the other end is located in the frame.
상기 플래튼 플레이트(60)는 상기 제2스프링(S2)에 의해 상시 하방으로 탄성압력을 받는다. 따라서 상기 플래튼 플레이트(60)의 하부로 리프터(51)가 진입하면 플래튼 플레이트가 피드 롤러(70)의 축을 중심으로 상승하고, 이 때 제2스프링(S2)은 탄성변형된다. 따라서 리프터(51)가 후퇴하면 제2스프링의 탄성복원력에 의해 피드 롤러(70)의 축을 중심으로 플래튼 플레이트(60)가 회전하여 플래튼 롤러(63)가 하강하는 것이다.The platen plate 60 is always subjected to an elastic pressure downward by the second spring (S2). Therefore, when the lifter 51 enters the lower portion of the platen plate 60, the platen plate rises around the axis of the feed roller 70, and the second spring S2 is elastically deformed. Therefore, when the lifter 51 is retracted, the platen plate 60 rotates about the axis of the feed roller 70 by the elastic restoring force of the second spring, and the platen roller 63 descends.
도 10 및 도 11을 참조하여 플래튼 롤러(63)가 헤드(40)의 아래에서 승강하는 동작을 설명한다. 10 and 11, the operation of the platen roller 63 to move up and down under the head 40 will be described.
도 10은 플래튼 플레이트(60)의 하부로 리프터(51)가 진입한 상태를 나타낸 것이다. 도시된 바와 같이, 슬라이드 플레이트(50)의 전진으로 리프터(51)가 플래튼 플레이트(60)의 하부로 진입하면 플래튼 플레이트가 피드롤러(70)의 축을 중심으로 회전하여 플래튼 롤러(63)가 상승하게 된다. 이 때, 헤드(40)에 형성된 발열소자(41)와 갭을 형성하면서 밀착되는데, 상기 갭은 기록매체의 두께보다는 작다. 10 shows a state in which the lifter 51 has entered the lower portion of the platen plate 60. As shown, when the lifter 51 enters the lower portion of the platen plate 60 due to the advancement of the slide plate 50, the platen plate rotates around the axis of the feeder roller 70 to make the platen roller 63 Will rise. At this time, the heat generating element 41 formed in the head 40 is in close contact with the gap, which is smaller than the thickness of the recording medium.
한편, 헤드의 하부에는 잉크리본이 장착되어 있는 상태이고, 이 상태에서 상기 헤드(40)와 플래튼 롤러(63) 사이에 기록매체가 진입하면, 플래튼 롤러(63)는 제1스프링(S1)의 작용으로 탄성적으로 하측으로 이동한다. 따라서 제1스프링의 탄성력에 의해 발열소자(41)에 잉크리본(R)과 기록매체(P)가 탄성적으로 밀착된 상태로 화상을 형성한다. On the other hand, when the ink ribbon is mounted on the lower portion of the head, and when the recording medium enters between the head 40 and the platen roller 63 in this state, the platen roller 63 is the first spring (S1) ) Moves elastically downward. Accordingly, an image is formed with the ink ribbon R and the recording medium P elastically in close contact with the heating element 41 by the elastic force of the first spring.
다음으로, 도 11을 참조하면, 상기 슬라이드 플레이트(50)의 후진으로 리프터(51)가 플래튼 플레이(60)의 하부에서 후퇴하게 되면, 상기 제2스프링(S2)에 의해 상기 플래튼 플레이트(60)의 일측은 상기 피드롤러(70)의 축을 중심으로 회전하여 플래튼 롤러(63)가 하강하게 된다. 따라서 플래튼 롤러(63)와 헤드(40) 사이에 형성된 갭이 벌어지게 되는 것이다. Next, referring to Figure 11, when the lifter 51 is retracted from the lower portion of the platen play 60 due to the reverse of the slide plate 50, the platen plate (2) by the second spring (S2) One side of the 60) is rotated around the axis of the feed roller 70, the platen roller 63 is lowered. Therefore, the gap formed between the platen roller 63 and the head 40 is widened.
이하에서는 본 발명에 의한 염료 승화형 프린터의 작동상태 및 인쇄방법을 설명한다. Hereinafter, an operation state and a printing method of the dye sublimation printer according to the present invention will be described.
본 발명에 의한 염료 승화형 프린터의 인쇄방법은 기록매체의 상부에 픽업롤러를 밀착시킨 상태에서 픽업롤러를 정회전하여 기록매체를 전방으로 이송하는 픽업단계와, 피드롤러를 역회전하여 기록매체를 후방으로 이송하는 리와인딩단계와, 상기 피드롤러를 정회전하여 기록매체를 전방으로 이송함과 동시에 리본을 이송하여 화상을 형성하는 프린팅단계를 포함한다. The printing method of the dye sublimation type printer according to the present invention includes a pickup step of forwarding the recording medium by rotating the pickup roller forward while the pickup roller is in close contact with the top of the recording medium, and rotating the feed roller backward to reverse the recording medium. It includes a rewinding step of transferring to and a printing step of transferring the recording medium forward by rotating the feed roller forward and simultaneously transferring the ribbon to form an image.
먼저, 도 12를 참조하여 픽업단계를 설명한다. 도시된 바와 같이, 픽업모터(M)를 역방향으로 회전하면 픽업모터의 구동력은 감속기어(G)를 거쳐 아이들 기어(30)로 전달된다. 상기 아이들 기어(30)의 일측에 형성된 회전돌기(30a)는 종방향의 가이드 홈(52a)에 구속되어 있는데, 상기 아이들 기어와 회전돌기(30a)가 회전하면서 가이드 홈(52a)을 아이들 기어의 축(31)의 후측으로 이동시킨다. 그에 따라 픽업 플레이트(52)도 후측으로 후퇴한다. First, the pickup step will be described with reference to FIG. 12. As illustrated, when the pickup motor M is rotated in the reverse direction, the driving force of the pickup motor is transmitted to the idle gear 30 via the reduction gear G. The rotation protrusion (30a) formed on one side of the idle gear 30 is constrained to the longitudinal guide groove (52a), the idle gear and the rotating protrusion (30a) rotates the guide groove (52a) of the idle gear It moves to the rear side of the shaft 31. Accordingly, the pickup plate 52 is also retracted to the rear side.
한편, 픽업 플레이트(52)가 후측으로 후퇴하면 픽업레버의 픽업돌기(32a)는 픽업플레이트(52)의 내측에 형성된 가이드 레일(56)의 상부레일(56a)에 위치된다(도 5 참조). 이러한 동작으로 픽업레버(32)는 아이들 기어의 축(31)을 중심으로 회전하여 픽업롤러(20)를 하강시킨다. 이와 같이 하강된 픽업롤러(20)는 수납부(10)에 적층된 기록매체의 상부에 밀착되며, 픽업모터의 구동력이 아이들 기어(30)와 픽업기어(22)를 통해 전달되어 하강한 픽업롤러(20)가 기록매체를 전방으로 공급하는 것이다. On the other hand, when the pickup plate 52 is retracted to the rear side, the pickup projection 32a of the pickup lever is located on the upper rail 56a of the guide rail 56 formed inside the pickup plate 52 (see FIG. 5). In this operation, the pickup lever 32 rotates around the shaft 31 of the idle gear to lower the pickup roller 20. The lowered pickup roller 20 is in close contact with the upper portion of the recording medium stacked in the storage unit 10, and the driving force of the pickup motor is transmitted through the idle gear 30 and the pickup gear 22 to descend the pickup roller. (20) is to supply the recording medium forward.
또한 상기 가이드 바(53)도 픽업 플레이트(52)와 함께 후진하므로 스윙돌기(82)는 가이드 바(53)의 저부에 위치된다. 따라서 스윙레버(80)는 피드 롤러(70)의 축을 중심으로 반시계방향으로 회전하게 되어 스윙기어(72)와 테이크업 릴 기어(14)는 치합이 해제된다. In addition, since the guide bar 53 is also retracted together with the pickup plate 52, the swing projection 82 is located at the bottom of the guide bar 53. Therefore, the swing lever 80 is rotated counterclockwise about the axis of the feed roller 70, so that the engagement between the swing gear 72 and the take-up reel gear 14 is released.
이 때, 상기 픽업 플레이트(52)와 일체 형성된 슬라이드 플레이트(50)도 후진하게 된다. 따라서 리프터(51)는 플래튼 플레이트(60)의 하부에서 후퇴하므로 플래튼 롤러(63)는 피드 롤러(70)의 축을 중심으로 회전하여 하강한다(도 11 (a)참조).At this time, the slide plate 50 integrally formed with the pickup plate 52 is also reversed. Therefore, the lifter 51 is retracted from the lower portion of the platen plate 60, so that the platen roller 63 rotates around the axis of the feed roller 70 to descend (see FIG. 11 (a)).
따라서 픽업단계에서 상기 픽업롤러(20)가 기록매체를 전방으로 공급할 때, 플래튼 롤러(63)는 하강하므로 헤드(40)에 기록매체가 밀착되지 않아 인쇄가 이루어지지 않고, 또한 테이크업 릴 기어(14)가 구동되지 않으므로 잉크리본도 이송되지 않는 상태에서 단지 기록매체만 전방으로 공급되는 것이다. Therefore, when the pickup roller 20 supplies the recording medium to the front in the pick-up step, the platen roller 63 is lowered, so that the recording medium is not in close contact with the head 40, so that printing is not performed, and also take-up reel gear Since (14) is not driven, only the recording medium is fed forward without the ink ribbon being conveyed.
다음으로, 도 13을 참조하여 리와인딩단계를 설명한다. 도시된 바와 같이, 상기 픽업모터를 정방향으로 회전하면 상기 회전돌기(30a)는 아이들 기어의 축(31)의 전측에 위치하고, 가이드 홈(52a)도 전측으로 이동한다. 즉, 회전돌기(30a)의 반시계방향 회전은 픽업 플레이트(52)를 전진시키는 것이다. 특히, 상기 회전돌기(30a)는 가이드 홈(52a)의 하부에 위치되어 있음을 알 수 있다. 이와 같이 픽업 플레이트(52)의 전진으로 인해 픽업돌기(32a)는 가이드 레일 중 하부레일(56b)에 위치된다. 따라서 상기 픽업레버(32)는 아이들 기어의 축(31)을 중심으로 회전하여 픽업롤러(20)를 상승시킨다(도 6 참조). Next, the rewinding step will be described with reference to FIG. 13. As shown, when the pickup motor rotates in the forward direction, the rotation protrusion 30a is located on the front side of the shaft 31 of the idle gear, and the guide groove 52a also moves to the front side. That is, the counterclockwise rotation of the rotating projection 30a advances the pickup plate 52. In particular, it can be seen that the rotating projection (30a) is located in the lower portion of the guide groove (52a). As such, due to the advancement of the pickup plate 52, the pickup protrusion 32a is positioned on the lower rail 56b among the guide rails. Therefore, the pickup lever 32 rotates around the shaft 31 of the idle gear to raise the pickup roller 20 (see FIG. 6).
또한, 상기 픽업 플레이트(52)와 일체형성된 슬라이드 플레이트(50)가 전진하지만, 리프터(51)가 플래튼 플레이트(60)의 하부로 진입하기 전까지만 전진시킨다. 따라서 플래튼 롤러(63)는 헤드(40)의 아래에서 하강상태를 유지한다(도 11 (a)참조). In addition, although the slide plate 50 integrally formed with the pickup plate 52 advances, only the lifter 51 advances until it enters the lower portion of the platen plate 60. Therefore, the platen roller 63 maintains the lowered state under the head 40 (see Fig. 11 (a)).
또한 상기 가이드 바(53)도 픽업 플레이트(52)와 함께 전진하지만, 스윙돌기(82)가 도피홈(54)으로 도피되기 전 상태이다. 따라서 스윙레버(80)는 피드 롤러(70)의 축을 중심으로 회전되지 않기 때문에 스윙기어(72)와 테이크업 릴 기어(14)는 여전히 치합되지 않는다.In addition, the guide bar 53 is also advanced with the pickup plate 52, but before the swing projection 82 is escaped to the escape groove 54. Therefore, since the swing lever 80 is not rotated about the axis of the feed roller 70, the swing gear 72 and the take-up reel gear 14 are still not engaged.
따라서 리와인딩단계에 의해 피드 롤러(70)가 기록매체를 후방(인쇄시작점)으로 이송할 때, 픽업롤러)20(는 상승하고, 플래튼 롤러(63)도 하강상태를 유지하기 때문에 기록매체가 후방으로 이송될 때 간섭되지 않는다. Therefore, when the feed roller 70 transfers the recording medium to the rear (start of printing) by the rewinding step, the pick-up roller 20 (the rise, and the platen roller 63 also maintains the falling state, so the recording medium is It does not interfere when transported backwards.
또한 스윙기어(72)와 테이크업 릴 기어(14)가 치합되지 않아 테이크업 릴 기어(14)가 구동되지 않으므로 잉크리본도 이송되지 않는 상태에서 단지 기록매체만 후방, 즉 인쇄 시작점으로 이송되는 것이다. In addition, since the take-up reel gear 14 is not driven because the swing gear 72 and the take-up reel gear 14 are not engaged, only the recording medium is transferred to the rear, that is, to the printing start point, because the ink ribbon is also not transferred. .
인쇄 시작점으로 이송된 기록매체의 전단은 피드 롤러(70)에 맞물려 있는 상태이다. The front end of the recording medium transferred to the printing start point is in a state of being engaged with the feed roller 70.
마지막으로 도 14를 참조하여 프린팅단계를 설명한다. 도시된 바와 같이, 픽업 모터를 구동하여 아이들 기어(30)를 반시계방향으로 더욱 회전하여 상기 회전돌기(30a)를 가이드 홈(52a)의 상부에 위치되도록 한다. 따라서 회전돌기(30a)의 회전은 픽업 플레이트(60)를 더욱 전진시키게 된다. 이와 같이 픽업 플레이트(52)가 더욱 전전하더라도 픽업돌기(32a)는 여전히 하부레일(56b)에 위치된다. 따라서 상기 픽업롤러(20)의 상승은 유지된다(도 6 참조). Finally, the printing step will be described with reference to FIG. 14. As illustrated, the pick-up motor is driven to further rotate the idle gear 30 counterclockwise so that the rotating protrusion 30a is positioned above the guide groove 52a. Therefore, the rotation of the rotating projection 30a further advances the pickup plate 60. Even if the pickup plate 52 is further rotated as described above, the pickup protrusion 32a is still positioned on the lower rail 56b. Therefore, the lift of the pickup roller 20 is maintained (see FIG. 6).
이와 같이 상기 픽업 플레이트(52)가 더욱 전진하면, 이와 일체형성된 슬라이드 플레이트(50)도 더욱 전진하게 되고, 그로 인해 리프터(51)가 플래튼 플레이트(60)의 하부로 진입하여 피드 롤러(70)의 축을 중심으로 플래튼 롤러(63)를 상승시킨다. As described above, when the pickup plate 52 is further advanced, the slide plate 50 integrally formed therewith is further advanced, whereby the lifter 51 enters the lower portion of the platen plate 60 to feed the roller 70. The platen roller 63 is raised around the axis of.
이와 동시에 상기 슬라이드 플레이트(50)의 전진으로 스윙돌기(82)는 가이드 바(53)의 저부에 형성된 도피홈(54)에 위치된다. 이 상태에서 피드 롤러(70)에 피드 모터의 구동력이 전달되어 회전하게 되면 피드 기어(72)의 토크에 의해 스윙레버(80)가 피드 롤러(70)의 축을 중심으로 회전하게 된다. 이와 같이 스윙레버(80)가 회전할 수 있는 것은 스윙돌기(82)가 가이드 바의 도피홈(54)에 위치될 때만 가능하다. 이러한 동작으로 스윙기어(72)가 비로소 테이크업 릴 기어(14)에 치합하게 되는 것이다. At the same time, as the slide plate 50 advances, the swing protrusion 82 is located in the escape groove 54 formed at the bottom of the guide bar 53. In this state, when the driving force of the feed motor is transmitted to the feed roller 70 and rotates, the swing lever 80 rotates about the axis of the feed roller 70 by the torque of the feed gear 72. The swing lever 80 can be rotated in this way is possible only when the swing projection 82 is located in the escape groove 54 of the guide bar. In this way, the swing gear 72 is finally engaged with the take-up reel gear 14.
따라서 상기 피드 모터의 구동으로 피드 롤러(70)가 회전하면서 기록매체를 헤드(40)와 플래튼 롤러(63) 사이로 이송하고, 이와 함께 테이크업 릴 기어(14)를 구동하여 잉크리본을 권취릴(12)에 감으면서 이송하는 것이다. Therefore, the feed roller 70 is rotated by the drive of the feed motor, the recording medium is transferred between the head 40 and the platen roller 63, and the take-up reel gear 14 is driven to wind the ink ribbon. (12) It is conveyed while being wound.
다시 말해, 플래튼 롤러(63)를 상승시켜 헤드(40)의 하부에 형성된 발열소자(41)에 잉크리본(R)과 기록매체(P)를 밀착시키고, 이 상태에서 기록매체와 잉크리본을 일정한 속도로 이송하면서 잉크리본의 염료를 승화시켜 기록매체에 화상을 형성하는 것이다. In other words, by raising the platen roller 63, the ink ribbon R and the recording medium P are brought into close contact with the heating element 41 formed under the head 40, and in this state, the recording medium and the ink ribbon are An image is formed on a recording medium by sublimating the dye of an ink ribbon while transferring at a constant speed.
따라서 프린팅 단계에서는 픽업롤러(20)와 플래튼 롤러(63)는 상승상태이고, 스윙기어(72)와 테이크업 릴 기어(14)가 치합된다. 이 상태에서 피드 롤러(70)를 회전하면 기록매체와 잉크리본이 전방으로 이송되는 것이다. Therefore, in the printing step, the pickup roller 20 and the platen roller 63 are in an elevated state, and the swing gear 72 and the take-up reel gear 14 are engaged. In this state, when the feed roller 70 is rotated, the recording medium and the ink ribbon are transferred forward.
또한 염료 승화형 프린터는 시안, 마젠타, 옐로우 등 세가지 색상의 염료가 도포된 잉크리본을 이송하면서 각 염료를 기록매체에 승화시켜야 한다. In addition, the dye sublimation printer must sublimate each dye on the recording medium while transferring the ink ribbon coated with three colors of dyes such as cyan, magenta, and yellow.
따라서 상기 리와인딩단계와 프린팅단계를 세번 반복하여 하나의 화상을 형성한다. Therefore, the rewinding step and the printing step are repeated three times to form a single image.
한편, 프레임 또는 기록매체가 수납되는 수납부의 일측에는 슬라이드 플레이트의 위치를 감지하는 센서(e1~e3)가 구비된다. 상기 센서는 수발광센서나 압접센서 등 공지의 수단을 다양하게 적용할 수 있다. 또한 슬라이드 플레이트(50)에는 상기 센서에 의해 위치를 감지하기 위한 감지부(55)가 구비된다. On the other hand, sensors (e1 to e3) for detecting the position of the slide plate are provided on one side of the storage unit in which the frame or the recording medium is stored. The sensor can be applied to a variety of known means such as a light emitting sensor or pressure sensor. In addition, the slide plate 50 is provided with a detection unit 55 for detecting the position by the sensor.
본 발명에 따르면, 부품 수가 획기적으로 감소하고 구조가 매우 단순하며, 각 스텝에 따라 픽업롤러, 플래튼롤러 및 테이크업 릴 기어의 구동을 제어할 수 있다.
