본 고안은 비디오 테이프 레코오더의 클러치 변환장치에 관한 것으로, 특히 플레이 동작시 권취릴 테이블에 의하여 테이프를 감아 들일때 캡스턴 축을 빠져나오는 테이프를 일정한 텐션으로 감아들이기 위하여 필요한 클러치 기구에 있어서 그 변환밸치에 관한 것이다.The present invention relates to a clutch converter of a video tape recorder, and more particularly, to a clutch mechanism necessary for winding a tape exiting a capstan shaft with a constant tension when the tape is rolled up by a winding table during a play operation. It is about.

종래의 클러치 변환장치는 제1도 및 제2도에 그 전형적인 일 실시형태를 도시한 바와같이, 구동모우터(도시되지 않음)로부터 벨트(21)를 통하여 회전되어 구동풀리(22)와, 그 구동풀리(22)에 벨트(23)로 연결되어 회전되는 클러치 회전판(24)과, 이 클러치 회전판(24)의 회전을 펠트(25)를 통하여 전달받아 일정한 토오크로 회전하는 종동기구(26)가 구비되어 있고, 종동기구(26)는 구동레버(27)에 따라 작동하는 연결레버(28)에 의하여 승강하게 된 중간 연결기어(29)가 교합 또는 분리되도록 설치되어 있으며, 중간 연결기어(29)의 회전은 릴 구동풀리(30)와 아이들러(31)를 통하여 릴테이블(32)에 전달되도록 되어있다.A conventional clutch converter is rotated through a belt 21 from a drive motor (not shown), as shown in FIGS. 1 and 2, to drive pulley 22, and The clutch rotary plate 24 which is connected to the drive pulley 22 by the belt 23 and rotated, and the driven mechanism 26 which receives the rotation of the clutch rotary plate 24 through the felt 25 and rotates with a constant torque are provided. It is provided, the driven mechanism 26 is installed so that the intermediate connecting gear 29, which is raised and lowered by the connecting lever 28 that operates in accordance with the drive lever 27, the interlocking gear 29, The rotation of is transmitted to the reel table 32 through the reel drive pulley 30 and the idler 31.

이와같은 종래기술은 제1a도에 도시한 바와같이, 중간연결기어(29)가 상승하여 종동기구(26)에 교합되면 종동기구(26)의 회전력은 연결기어(29)와 구동풀리(30) 및 아이들러(31)를 통하여 릴테이블(32)에 전달되며 이에 따라서 릴테이블(32)은 적절한 회전토오크로 회전하여 테이프를 플레이 속도로 감아들인다.In the related art, as shown in FIG. 1A, when the intermediate connecting gear 29 rises and engages the driven mechanism 26, the rotational force of the driven mechanism 26 is connected to the connecting gear 29 and the driving pulley 30. And to the reel table 32 via the idler 31, whereby the reel table 32 is rotated to an appropriate rotational torque to wind the tape at play speed.

또한, 빨리감기 및 되감기 동작시에는 제1b도에 도시한 바와같이, 구동레버(27)가 시계방향으로 회전함에 따라 연결레버(28)가 반시계 방향으로 회전하여 중간 연결기어(29)를 하강시키게 되므로 종동기구(26)와 분리되는 대신에 구동풀리(22)와 직접 결합되어 구동풀리(22)의 회전력이 그대로 릴테이블(32)에 전달되어 테이프를 매우 빠른 속도로 감아들인다.In the fast-forwarding and rewinding operation, as shown in FIG. 1B, as the driving lever 27 rotates clockwise, the connecting lever 28 rotates counterclockwise to lower the intermediate connecting gear 29. Instead of being separated from the driven mechanism 26, the driving force is directly coupled to the pulley 22 so that the rotational force of the driving pulley 22 is transmitted to the reel table 32 as it is, thereby winding the tape at a very high speed.

그러나, 이와같은 종래의 장치는 구동레버(27)와 연결레버(28)가 상하로 회동하여 연결레버(29)를 상하로 승강시키는 구조로 되어 있으므로 각종 내장부품이 대체로 평면운동을 하는 비디오 테이프 레코더에 있어서 평면운동을 상하운동으로 바꾸어 주는 복잡한 구성이 요구되어 제품의 높이 소형화에 저해되는 문제점이 있었으며, 이러한 이유 때문에 테이프의 로우딩 또는 언로우딩 메카니즘에 로우딩링이 사용되고 있는 기종에서는 상기한 종래의 클러치 변환구조를 채용하지 못하는 문제점이 있었다.However, such a conventional apparatus has a structure in which the driving lever 27 and the connecting lever 28 rotate up and down to raise and lower the connecting lever 29, so that various built-in components are generally planar. In order to reduce the height of the product, there is a problem in that the complicated configuration for changing the planar motion to the vertical motion is required, and for this reason, in the model in which the loading ring is used for the tape loading or unloading mechanism, There was a problem in not employing the clutch conversion structure.

본 고안은 이와같은 종래의 문제점을 감안하여 안출한 것으로, 적은 공간에서 간단한 구조로 클러치 변화장치를 구성하여 구동시키도록 하는데 목적이 있는 것인바, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in view of such a conventional problem, and the object is to configure and drive the clutch change device with a simple structure in a small space, which will be described in detail with reference to the accompanying drawings.

제2도 및 제3도에 도시한 바와같이, 릴테이블(1)에 아이들러(2)를 접촉되게 착설하고, 이 아이들러(2)는 축(3)으로 축설된 종동기구(4)의 릴구동풀리(5)에 접하도록 하며 종동기구(4)의 하측에는 펠트(6)를 접착하여 이에 스프링(7)으로 밀착되는 클러치 회전판(8)을 부착하고 상기 종동기구(4)와 클러치 회전판(8)에는 연결기어(9)가 접리될 수 있도록 한 것에 있어서, 상기 연결기어(9)가 유착된 연결레버(10)와 구동레버(11)를 베이스 플레이트(도시되지 않음)에 축핀(10')(11')으로 각각 축설하고 연결레버(10)와 구동레버(11)의 접촉단부에 스프링(12)(13)을 각각 탄력 설치하며 구동레버(11)의 타단부에는 로우딩링(14)에 일체로 형성된 캠 플레이트(15)의 외주면에 접촉되는 캠 종동부(16)를 형성함과 아울러 캠플레이트(15)의 외주면에는 구동레버(11)의 캠 종동부(16)가 삽입 또는 이탈되는 캠곡면(17)을 형성한 것으로, 도면중 미설명부호 18은 클러치회전판(8)의 하측부에 형성된 구동풀리이고, 19는 구동모터의 구동력을 구동풀리(18)에 전달하는 벨트를 보인 것이다.As shown in FIG. 2 and FIG. 3, the idler 2 is installed in contact with the reel table 1, and this idler 2 is driven by the reel driving of the driven mechanism 4 arranged in the shaft 3. The clutch 6 is attached to the lower side of the driven mechanism 4 and the felt 6 is attached to the lower side of the driven mechanism 4, and the clutch rotary plate 8, which is in close contact with the spring 7, is attached to the driven mechanism 4 and the clutch rotary plate 8. ), The connecting gear 9 can be folded, and the connecting lever 10 and the driving lever 11 to which the connecting gear 9 is bonded are connected to the base plate (not shown). And the springs 12 and 13 are elastically installed at the contact ends of the connecting lever 10 and the driving lever 11, respectively, and the other end of the driving lever 11 is connected to the loading ring 14, respectively. The cam follower 16 is formed in contact with the outer circumferential surface of the cam plate 15 integrally formed, and the cam follower 16 of the drive lever 11 is inserted into the outer circumferential surface of the cam plate 15. Alternatively, a cam curved surface 17 is formed to be separated. In the drawing, reference numeral 18 denotes a driving pulley formed at a lower side of the clutch rotating plate 8, and 19 is a belt for transmitting a driving force of the driving motor to the driving pulley 18. Will be shown.

이와같이된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

제2a도와 제3a도는 본 고안 클러치 변환 장치의 플레이 상태를 보인 평면도 및 정단면도로서, 이와같은 플레이 상태에서는 구동레버(9)의 캠종동부(16)가 로우딩링(14)의 외주면에 접촉되고 연결기어(9)가 종동기구(4)와 클러치 회전판(8)에서 분리되어 있다. 이때에는 구동모터의 구동력이 벨트(19)를 통하여 구동풀리(18)에 전달되면, 그 구동력이 클러치 회전판(8), 펠트(6), 종동기구(4), 릴구동풀리(5) 및 아이들러(2)를 통하여 릴테이블(1)에 전달되므로 펠트(6)와 스프링(7)에 의하여 일정한 회전토오크가 릴 테이블(1)에 전달된다.2a and 3a are a plan view and a front sectional view showing the play state of the clutch converter of the present invention, in which the cam follower 16 of the drive lever 9 is in contact with and connected to the outer circumferential surface of the loading ring 14; The gear 9 is separated from the follower mechanism 4 and the clutch rotary plate 8. At this time, when the driving force of the driving motor is transmitted to the driving pulley 18 through the belt 19, the driving force is transmitted to the clutch rotating plate 8, the felt 6, the driven mechanism 4, the reel driving pulley 5 and the idler. Since it is transmitted to the reel table 1 through (2), a constant rotational torque is transmitted to the reel table 1 by the felt 6 and the spring 7.

한편, 빨리감기 또는 되감기 동작시에는 제2b도, 제3b도와 같이 로우딩 모우터(도시되지 않음)의 구동력으로 로우딩링(14)이 회전함에 따라 스프링(13)의 힘에 의해 구동레버(11)의 캠종동부(16)가 캠플레이트(15)의 캠곡면(17)으로 삽입되면서, 구동레버(11)가 시계방향으로 약간 회동하고 이에따라 스프링(12)의 힘에 의해 연결레버(10)가 반시계방향으로 회전하게 되므로 연결레버(10)에 유착된 연결기어(9)가 종동기구(4)와 클러치회전판(8)에 접촉된다.On the other hand, during the fast-forward or rewind operation, as the driving ring 11 rotates with the driving force of the loading motor (not shown) as shown in FIGS. 2B and 3B, the driving lever 11 is driven by the force of the spring 13. Cam follower 16 is inserted into the cam curved surface 17 of the cam plate 15, the drive lever 11 is rotated slightly in the clockwise direction, and accordingly the connecting lever 10 by the force of the spring 12 Since it rotates counterclockwise, the connecting gear 9 adhered to the connecting lever 10 is in contact with the driven mechanism 4 and the clutch rotating plate 8.

이때에는 구동풀리(18)의 구동력이 클러치회전판(8), 연결기어(9), 종동기구(4)를 통하여 릴테이블(1)에 전달된다. 따라서 구동풀리(18)의 구동력이 마찰클러치의 영향을 받지 않고 릴테이블(1)에 직접 전달 되므로 테이프를 빠른 속도로 감을 수 있게 된다.At this time, the driving force of the drive pulley 18 is transmitted to the reel table 1 through the clutch rotating plate 8, the connecting gear 9, and the driven mechanism (4). Therefore, since the driving force of the driving pulley 18 is directly transmitted to the reel table 1 without being affected by the friction clutch, the tape can be wound at a high speed.

이러한 제2b도와 제3b도의 상태에서 플레이모드로 변한때에는 로우딩링(14)의 회전에 따라 구동레버(9)의 캠종동부(16)가 캠플레이트(15)의 캠곡면(17)에 삽입되어 제2a도와 제3b도의 상태로 복귀 된다.When the driving mode is changed to the play mode in the state of FIGS. 2B and 3B, the cam follower 16 of the driving lever 9 is inserted into the cam curved surface 17 of the cam plate 15 in response to the rotation of the loading ring 14. It returns to the state of 2a and 3b.

상술한 바와같은 본 고안은 연결기어(9)가 유착된 연결레버(10)와 구동레버(11)의 접촉단부에 스프링(12)(13)을 각각 탄력 설치하고 구동레버(11)의 타단부에는 로우딩링(14)의 캠플레이트(15)에 형성된 캠곡면(17)에 삽입 또는 이탈되는 캠종동부(16)를 형성한 간단한 구성에 의하여 구동레버(11)와 연결레버(10)가 평면상에서 회동하여 연결기어(9)를 종동기구(4)와 클러치 회전판(8)에 접리하도록 하였으므로, 클러치변환장치가 간소화되어 제품의 소형화에 기여하는 이점이 있으며, 또한 로우딩링을 이용하여 테이프를 로우딩 또는 언로우딩시키는 제품에 쉽게 적용할 수 있는 효과가 있다.According to the present invention as described above, the springs 12 and 13 are elastically installed at the contact ends of the connecting lever 10 and the driving lever 11 to which the connecting gear 9 is attached, respectively, and the other end of the driving lever 11. The drive lever 11 and the connecting lever 10 are planarly formed by a simple configuration in which a cam follower 16 is inserted into or removed from the cam curved surface 17 formed on the cam plate 15 of the rowing ring 14. Since the connecting gear 9 is folded to the driven mechanism 4 and the clutch rotating plate 8 by rotation, the clutch converting device is simplified, contributing to the miniaturization of the product, and also the tape is loaded using the loading ring. Or it can be easily applied to unloading products.
