본 고안은 브이씨알의 데크 메카니즘에서 릴 구동장치에 관한 것으로, 특히 릴 구동시 플레이와 리뷰 모드에서의 구동토오크의 차이를 주기에 적합하도록 한 릴구동장치에 관한 것이다.The present invention relates to a reel driving device in the deck mechanism of V-Cal, and more particularly to a reel driving device adapted to give a difference in driving torque in play and review modes when driving a reel.
종래에는 제1도에 도시한 바와 같이, 구동모터에 벨트로 연결되어 있는 주동풀리와 일체로 된 고무마찰차(1)가 플레이모드시 시계방향으로 회전하고 외주면이 고무로 되어있는 아이들러(2)가 고무마찰차(1)와 스프링(3)력에 의하여 압착된 상태로 반시계방향으로 회전하면서 아이들러(2)를 지탱시켜주는 지지판(4)이 축핀(5)을 중심으로 시계방향으로 이동되면서 권취릴(6)에 밀착되는 때까지 이동하며 가상선으로 도시한 밀착위치에서 권치릴(6)을 회전시켜 주는데 이때 구동토오크는 고무마찰차(1)의 구동력이 결정하여 주게된다.Conventionally, as shown in FIG. 1, an idler 2 in which a rubber friction car 1 integrated with a driving pulley connected to a drive motor by a belt rotates clockwise in the play mode and whose outer peripheral surface is made of rubber The support plate 4 supporting the idler 2 while being rotated counterclockwise while being compressed by the rubber friction car 1 and the spring 3 force is moved clockwise about the shaft pin 5. It moves until it is in close contact with the take-up reel 6 and rotates the take-up reel 6 at the close position shown by the imaginary line. At this time, the driving torque is determined by the driving force of the rubber friction car 1.
여기서 아이들러지지판(4)이 시계방향으로 회전하려는 힘에 의하여 가상선의 권취릴(6)구동위치에서 아이들러(2)의 축(2')이 끼워지는 연결판(8)의 보스(8a)를 지지판(4)에 형성된 홈(4a)의 일측면(4a')이 밀어 권취릴(6)에 구동력을 전달하여 주도록 되어 있으므로 고무마찰차(1)의 구동력이 손실없이 아이들러(2)에 전달될 수 있다. 한편, 리뷰모드 수행시에는 구동모터가 역회전함에 따라 플레이시의 역방향으로 진행되어 아이들러(2)가 공급릴(7)에 접촉되고 이때 지지판(4)에 형성된 홈(4a)의 타측면(4a＂)이 보스(8a)를 밀어 공급릴97)에 구동력이 전달되게 되어 있다.The support plate boss 8a of the connecting plate 8 into which the shaft 2 'of the idler 2 is fitted at the driving position of the winding reel 6 of the virtual line by a force that the idler support plate 4 rotates clockwise. Since one side 4a 'of the groove 4a formed in the 4 is pushed to transmit the driving force to the winding reel 6, the driving force of the rubber friction vehicle 1 can be transmitted to the idler 2 without loss. have. On the other hand, when the review mode is performed, the driving motor rotates in the reverse direction during play, and the idler 2 contacts the supply reel 7, and at this time, the other side 4a of the groove 4a formed in the support plate 4. V) the driving force is transmitted to the supply reel 97 by pushing the boss 8a.
제1도 및 제2도에서 8b는 연결판(8)에 형성되어 축핀(5)이 끼워지는 안내공이고, 8c는 연결판(8)에 형성된 스프링걸이로서 이 스프링걸이(8c)에는 지지판(4)의 스프링걸이(4b)에 일단부가 고정된 인장스프링(3)의 타단부가 고정된다.In FIG. 1 and FIG. 2, 8b is a guide hole which is formed in the connecting plate 8, and the shaft pin 5 is fitted, 8c is a spring hook formed in the connecting plate 8, and this spring hanger 8c has a support plate ( The other end of the tension spring 3, one end of which is fixed to the spring hanger 4b of 4), is fixed.
그리고 4c는 지지판(4)의 선단부에 형성된 안내돌기이고, 8d는 연결판(8)의 선단부에 형성되어 안내돌기(4c)가 삽입안내되는 안내공이며, 9는 축핀(5)이 지지되는 브레키트이다.And 4c is a guide protrusion formed in the front end of the support plate 4, 8d is a guide hole formed in the front end of the connecting plate 8 is guide guide 4c is inserted guide, 9 is a bra which the shaft pin 5 is supported It's a kit.
그러나, 이와 같은 종래의 릴 구동장치는 아이들러(2)가 권취릴(6)또는 공급릴(7)을 구동시킬 때 지지판(4)에 형성된 홈(4a)의 일측면(4a') 또는 타측면(4a＂)이 연결판(8)의 중앙부에 일체로 형성된 보스(8a)를 밀어서 아이들러(2)가 권취릴(6)또는 공급릴(7)에 동일한 힘으로 압착되면서 구동력을 전달하여 플레이와 리뷰시 권취릴(6)과 공급릴(7)의 구동토오크가 동일하게 작용된다.However, such a conventional reel drive device has one side 4a 'or the other side of the groove 4a formed in the support plate 4 when the idler 2 drives the winding reel 6 or the supply reel 7. 4a 'pushes the boss 8a integrally formed at the center of the connecting plate 8 so that the idler 2 is pressed against the take-up reel 6 or the supply reel 7 with the same force to transmit driving force. During review, the driving torque of the take-up reel 6 and the supply reel 7 acts the same.
따라서 REV에서 높은 토오크값이 PLAY 시에도 작용하게 되어 PLAY 가 진행되는 경우 주행되는 테이프에 텐션이 과하게 걸리게 되고 테이프가 지나는 가이드 포스트들의 상하단 부위에 테이프가 심하게 마찰되어 손상되는 문제점이 있으며, 비디오 및 오디오신호 출력에도 영향을 미치게 되는 등 테이프의 안정주행을 기할 수 없는 결함이 있었다.Therefore, the high torque value in the REV also acts during PLAY. When the PLAY progresses, the tension is excessively applied to the running tape, and the tape is severely rubbed and damaged at the upper and lower portions of the guide posts through which the tape passes. There was a defect that could not stabilize the tape, such as affecting the signal output.
본 고안은 이와 같은 종래의 결함을 해소하기 위하여 안출한 것으로, 아이들러의 지지판과 안내판의 일부 형상을 변경시키고 지지판의 연결판에 기존의 인장코일스프링 설치방향과 대략 직교되는 방향으로 또 하나의 인장코일스프링을 연결하여, 아이들러가 권취릴축에 접속된 때에는 신설된 인장코일스프링의 탄력에 의하여 압착되게 하고, 아이들러가 공급릴측에 접촉된 때에는 종래와 마찬가지로 아이들러의 축지지용 보스가 지지들러에 의하여 밀리게 됨으로써 압착되게 하여 공급릴축 보다 적은 구동토오크가 권취릴에 걸리도록 한 것인바, 이러한 본 고안을 첨부한 도면 제3도 내지 제5도에 의하여 상세히 설명하면 다음과 같다.The present invention was devised to solve such a conventional defect, and another tension coil in a direction substantially perpendicular to the existing tension coil spring installation direction on the connection plate of the idler by changing some shapes of the support plate and the guide plate of the idler. By connecting the spring, when the idler is connected to the take-up reel shaft, it is compressed by the elasticity of the new tension coil spring, and when the idler is in contact with the supply reel side, the shaft support boss of the idler is pushed by the supporter as in the prior art. It is compressed so that the driving torque less than the supply reel shaft is caught on the take-up reel, described in detail with reference to the drawings 3 to 5 attached to the present invention as follows.
제3도는 본 고안 릴구동장치의 구성을 보인 평면도이고, 제4도는 작용을 보인 평면도이며, 제5도는 본 고안 릴구동장치에서 요부인 아이들러지지판, 아이들러연결판 및 아이들러등을 발췌하여 보이고, 고무마찰차, 구동풀리등은 생략한 분해사시도로서, 이에 도시한 바와 같이, 축핀(5)에 회전가능하게 삽입설치된 지지판(4)의 스프링걸이(4b)와 지지판(4)의 하측에 안내공(8b)으로 삽입된 연결판(8)의 스프링 걸이(8c)간에는 인장코일 스프링(3)이 연결되고 연결판(8)에 유착된 아이들러(2)가 지지판(4) 하측에 축지된 고무마찰차(1)에 스프링력(3)으로 압접되어 있는 것에 있어서, 지지판(4)의 전방부에 양측면(4a')(4a＂)을 가지는 홈(4a)을 형성하는 대신에 접촉면(4a＂)을 형성하고 지지판(4)의 전방부 일측변부에는 보강리브(4d)를 하측으로 돌출형성하여 그 보강리브(4d)에 스프링걸이(4e)를 형성하고 연결판(8)에 일체로 형성된 보스(8a)일측에 스프링걸이(8E)를 형성하여 인장스프링(10)의 양단부를 상기 스프링걸이(4e)(8e)에 고정하며, 연결판(8)의 선단부에는 지지판(4)의 선단부에 형성된 안내돌기(4c)가 지지되는 ㄱ자형 안내편(8f)를 형성한 것으로, 도면중 미설명부호 9a는 브래키트(9)에 절곡형성한 스토퍼를 보인 것이다.Figure 3 is a plan view showing the configuration of the reel drive device of the present invention, Figure 4 is a plan view showing the action, Figure 5 shows the excerpts of the idler support plate, idler connecting plate and idler, etc. that is the main part of the reel drive device of the present invention, rubber Friction difference, drive pulley, etc. are omitted exploded perspective views, as shown in the guide hole (3) and the spring hook (4b) of the support plate (4) rotatably inserted in the shaft pin (5) and the lower side of the support plate (4). A rubber friction car in which a tension coil spring 3 is connected between the spring hooks 8c of the connecting plate 8 inserted into the connecting plate 8 and the idler 2 adhered to the connecting plate 8 is supported under the support plate 4. In contact with (1) by the spring force 3, instead of forming the groove 4a which has both side surfaces 4a 'and 4a' in the front part of the support plate 4, the contact surface 4a 'is made. And a reinforcing rib 4d protrudes downward on one side of the front portion of the support plate 4, and the reinforcing rib A spring hook 4e is formed at the bar 4d and a spring hook 8E is formed at one side of the boss 8a integrally formed at the connecting plate 8 so that both ends of the tension spring 10 are formed at the spring hook 4e. It is fixed to (8e), the end portion of the connecting plate (8) is formed with an L-shaped guide piece (8f) that is supported by the guide projection (4c) formed on the front end of the support plate 4, reference numeral 9a in the figure The stopper bent to the bracket 9 is shown.
이와 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as follows.
제3도는 상태에서 고무마찰차(1)가 별도의 구동원에서 전달된 구동력에 의하여 시계방향으로 회전하여 아이들러(2)가 제4도에 실선으로 도시한 바와 같이, 귄취릴(6)에 접촉된 상태에서는 아이들러(2)는 위치변화가 없게 되고 지지판(4)이 가상선으로 아이들러(2)는 위치변화가 없게되고 지지판(4)이 가상선으로 보인 바와 같이 시계방향으로 더 이동하여 브래키트(9)에 형성된 스토퍼(9a)에 의하여 규제되는 위치에서 멈추게 되므로 지지판(4)에 돌출된 스프링걸이(4e)와 아이들러(2)가 조립되어 있는 연결판(8)의 스프링걸이(8e)에 연결된 스프링(10)이 소정길이(S)만큼 신장되고 그 스프링(10)이 신장된 길이 만큼 아이들러(2)가 권취릴(6)에 구동토오크를 전달하게 된다.3 is a state in which the rubber friction car 1 is rotated clockwise by a driving force transmitted from a separate driving source so that the idler 2 is in contact with the guinea pig reel 6 as shown in FIG. In the state, the idler 2 has no change of position, the support plate 4 has no positional change, and the idler 2 has no change of position, and the support plate 4 has moved further clockwise as shown by the virtual line, whereby the bracket ( It is stopped at the position regulated by the stopper 9a formed in 9), so that the spring hook 4e protruding from the support plate 4 and the spring hook 8e of the connecting plate 8, on which the idler 2 is assembled, are connected. The spring 10 is extended by a predetermined length S, and the idler 2 transmits the driving torque to the take-up reel 6 as long as the spring 10 is extended.
따라서 스프링(10)의 장력에 따라 토오크를 자유자재로 조립할 수 있다.Therefore, the torque can be freely assembled according to the tension of the spring 10.
이와 같이 플레이시에서는 플레이 동작 가능한 토오크를 구동력의 원천인 고무마찰차(1)의 구동력과 관계없이 스프링(10)에 의하여 권취릴(6)의 구동력 조절이 가능하다.In this way, the playable torque can be adjusted by the spring 10 regardless of the driving force of the rubber friction car 1 which is the source of the driving force.
그리고, 아이들러(2)가 공급릴(7)에 접촉되는 리뷰 동작시에는 아이들러축(2')이 지지되는 보스(8A)가 지지판(4)의 접촉면(4a＂)에 직접 밀려서 마찰차(1)의 구동력이 전달되므로 강력한 토오크가 공급링(7)에 전달된다.In the review operation in which the idler 2 is in contact with the supply reel 7, the boss 8A on which the idler shaft 2 'is supported is pushed directly on the contact surface 4a' of the support plate 4, thereby providing a friction difference (1). Since the driving force of) is transmitted, a strong torque is transmitted to the supply ring (7).
따라서 리뷰모드와 플레이모드의 토오크전달에 변화를 줄 수 있다.Therefore, it is possible to change the torque transmission of the review mode and the play mode.
이상에서 설명한 바와 같이 된 본 고안은 플레이와 리뷰시 토오크변화에 의하여 플레시 토오크를 알맞게 줄 수 있어 테이프의 주행이 안정하게 되므로 테이프 주행중 손상 및 변형이 방지되며 테이프텐션이 안정하게 유지되므로 비디오 및 오디오신호 출력이 개선되는 이점이 있다.As described above, the present invention can provide the flash torque appropriately by the change of torque during play and review, so that the running of the tape is stabilized, thereby preventing damage and deformation during the tape running, and the tape tension is kept stable, so that the video and audio signals There is an advantage that the output is improved.
