본 고안은 VTR의 테이프 구동장치에서 테이프의 주행시에 테이프의 흐름을 원활하게 작동시킬 수 있는 VTR의 핀치로울러 구동 조립체에 관한 것이다.The present invention relates to a pinch roller drive assembly of the VTR that can smoothly operate the flow of the tape when the tape is running in the tape drive device of the VTR.
종래의 VTR에는 이러한 장치가 없었으며 최근에 생산된 VTR에서는 캠스턴(Capstan) 구동으로 주행시에 재생암(ARM)을 설치하였으나 재생암과 핀치로울러암은 링크 또는 기타 구동장치를 별도로 이용하여 암을 작동시키므로 구조가 복잡하여, 고장이 많이 발생하고 또한 기기의 신뢰성과 경쟁력이 떨어지는 결점이 있었다.Conventional VTRs do not have such a device, and recently produced VTRs installed a regeneration arm when driving with a capstan drive. However, the regeneration arm and the pinch roller arm use a link or other driving device to separate the arm. Because of its operation, the structure is complicated, and many defects occur, and the reliability and competitiveness of the device are inferior.
따라서 본 고안은 이와같은 종래의 결점을 해소하기 위해서 핀치로울러아암에 가이드홈을 형성시켜 재생아암에 조립된 축핀과 슬라이딩 되도록 외부의 구동장치를 이용하지 않고 핀치로울러 아암만을 이용하여 재생아암의 작동을 가능케한 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention forms a guide groove on the arm of the pinch roller in order to solve such a conventional drawback, and uses only the arm of the pinch roller to operate the regeneration arm without using an external driving device to slide with the shaft pin assembled to the regeneration arm. When described in detail the configuration and effect by the accompanying drawings as possible as follows.
핀치로울러(1)가 삽입된 축(2)과 회전축(3)을 압입 고정시키고 가이드홈(4)을 형성시켜서된 핀치로울러아암(5)을 구비하고 가이드로울러(6)가 삽입된 축핀(7)과 아암축(8)이 조립되어 구성된 재생아암(9)을 구비하여 상기 가이드홈(4)에 축핀(7)를 삽설하면서, 받침대(10)에 고정시킨 각각의 부시(11)(11')에 회전축(3)과 아암축(8)을 끼워맞춰 핀치로울러와 가이드로울러가 연동될 수 있도록 구성된 것으로서 미설명 부호 12, 12', 12"는 링크이고, 13, 13', 13", 13"'는 핀이며, 14는 스터드(Stud)인 것이다.A shaft pin (7) having a pinch roller arm (5) formed by press-fitting the shaft (2) into which the pinch roller (1) is inserted and the rotating shaft (3) and forming a guide groove (4), and the guide roller (6) inserted therein. ) And a bush (11 ') (11') fixed to the pedestal (10 ') with a regenerator arm (9) composed of assembled arm shafts (8) and inserting shaft pins (7) into the guide grooves (4). 12), 12 ', 12 "are links, 13, 13', 13", and 13 ", and 13", 13 " "'Is the pin, 14 is the stud.
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
도면 제 1 도에서는 보는 바와같이 재생아암(9)에 조립된 축핀(7)을 핀치로울러아암(5)에 형성된 가이드홈(4)에 연동되도록 끼우면서 회전축(3)과 아암축(8)을 받침대(10)에 고정되어 있는 부시(11)(11')에 각각 고정시키며, 또한 도면 제 2 도의 (a)에서 보는 바와 같이 핀치 로울러아암(5)에 랭크(12)(12')(12")을 핀(13)(13')(13")(13"')으로 연결시켰으며 또 링크(12")를 핀(13')으로 스터드(14)에 고정시켜서 소정의 구동수단에서 발생된 힘을 화살표 A방향으로 링크(12')에 인가하면 링크(12')가 작동되므로 링크(12)(12")가 핀(13')을 중심으로 회전되므로써 도면 제 2 도의 (b)에서와 같이 B방향으로 이동되므로 핀치로울러(1)를 축(2)에 삽입시킨 핀치로울러아암(5)은 부시(11)에 끼워져 있는 회전축(3)을 중심으로 시계방향으로 작동하게 되며 이때 가이드홈(4)에 끼워져 있는 축핀(7)을 가이드홈(4)을 따라 이동되기 때문에 재생아암(9)는 외부의 구동장치를 이용하지 않고도 핀치로울러아암(5)의 회전 작동으로 인하여 받침대(10)의 부시(11')에 끼워진 아암축(8)을 중심으로 시계방향으로 작동되므로 이에 고정된 가이드로울러(1)가 핀치로울러(1)와 연동되어 재생아암(9)의 기능을 완전히 할 수 있으며, 또한 구조가 간단하므로 고장율이 떨어져 기기의 신뢰도를 향상시켜 경쟁력을 높일 수 있는 효과가 있는 것이다.As shown in FIG. 1, the rotating shaft 3 and the arm shaft 8 are fitted while being interlocked with the guide pin 4 formed in the arm 5 by pinching the shaft pin 7 assembled to the regeneration arm 9. It is fixed to each of the bushes 11 and 11 'fixed to the pedestal 10, and also the ranks 12, 12' and 12 on the pinch roller arm 5 as shown in FIG. "" Is connected to pins 13, 13 ', 13 "and 13"' and the link 12 " is fixed to the stud 14 by pins 13 'to generate the desired drive means. When the applied force is applied to the link 12 'in the direction of the arrow A, the link 12' is activated, so that the link 12, 12 "is rotated about the pin 13 ', so that in FIG. As it moves in the B direction, the pinch roller arm 5 into which the pinch roller 1 is inserted into the shaft 2 is operated clockwise about the rotating shaft 3 fitted to the bush 11. Shaft pin (7) fitted in (4) Since the revolving arm 9 is moved along the guide groove 4, the arm shaft fitted to the bush 11 'of the pedestal 10 is rotated by the pinch roller arm 5 without using an external driving device. 8) Since it is operated clockwise around the center, the guide roller (1) fixed to it can interlock with the pinch roller (1) to complete the function of the play arm (9), and the structure is simple. There is an effect that can increase the competitiveness by improving the reliability.
