본 고안은 VTR, DAT등과 같은 자기기록 장치에서 테이프가 안정성 있게 주행하도록 하기 위한 핀치로울러를 구동하기 위한 장치에 관한 것이다.The present invention relates to an apparatus for driving a pinch roller for stably running a tape in a magnetic recording apparatus such as a VTR, a DAT, and the like.
VTR덱크의 핀치 로울러는 캡스턴 축과 핀치 로울러 사이로 지나갈 녹화 테이프를 캡스턴 축에 강제 접촉시켜 그 마찰력에 의해 녹화 테이프가 주행되도록 하는 중요 구성 요소중의 하나이다.The pinch roller of the VTR deck is one of the important components for forcibly contacting the capstan shaft with the tape tape passing between the capstan shaft and the pinch roller to drive the tape tape by the frictional force.
따라서, 이러한 기능을 가진 핀치 로울러는 녹화 테이프의 재생 또는 비재생에 따라 선택적으로 작동하게 된다. 이같은 선택적 작동은 카세트 테이프가 장전되는 것과 동시에 또는 그 후에 이뤄지는데, 마스터 캠 이 회전하면 그 힘이 링크를 거쳐 핀치 로울러에 전달되는 다관절 링크식 전달방식으로 구성되는 것이 일반적이다. 그런데, 종래에는 모두 4마디 연결방식으로 이뤄진 링크가 적용되고 있었다. 다관절 링크는 우선 링크의 마디수와 연결점이 많기 때문에 각 링크의 형상에 따른 금형의준비, 소요자재 등 제반 비용의 부담이 크고, 동력 전달과정에서 힘의 허비는 물론 작동시 기계적 소음이 큰 결점이 있었다.Therefore, the pinch roller having this function is selectively operated in accordance with the playback or non-playback of the recording tape. This selective operation takes place at the same time as or after the cassette tape is loaded. It is typically configured as a multi-joint linkage, in which the force is transmitted to the pinch rollers when the master cam is rotated. However, in the related art, all four-link links have been applied. Since the articulated link has a large number of nodes and connection points, the cost of preparing the mold and required materials according to the shape of each link is high, and it is a waste of power and mechanical noise during operation. There was this.
본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서 캠기어 및 링크를 사용하지 않고 기어와 토숀스프링을 이용하여 핀치로울러를 구동시킬 수 있도록 하여 간단한 구성에 의하여 작동시키므로 기기의 소형화를 이룰수 있으며 소음을 줄일 수 있도록 함을 본 고안의 목적으로 한다.The present invention was devised to solve the above problems, and can operate the pinch roller using a gear and a torsion spring without using a cam gear and a link. It is an object of the present invention to reduce the
상기 목적을 달성하기 위한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment for achieving the above object will be described in detail with reference to the accompanying drawings.
우선 제1도 및 제2도를 참조하여 본 고안의 구성을 설명하면 다수개의 기어들(1)로 이루어진 테이프 주행계(50)와 맞물려 회전하는 구동기어(2)의 축(2a)의 코일스프링(3)의 텐션부가 끼워지며 상기 구동기어의 상면에 상기 코일스프링(3)의 일단(3a)를 고정하고, 상기 스프링(3)의 타단(3b)은 축(4)에 축지되어 회동하는 레바(5)의 하단에 형성된 돌기(7)에 접촉하여 레바(5)를 동작시키며 상기 레바(5)의 작동에 따라 상측의 핀치로울러(6)가 캡스턴축(40)에 선택적으로 접촉 또는 이격되도록 작동시킬 수 있도록 하여서 된 것으로서 도면중 미설명 부호 10은 테이프, 20은 드럼, 30은 구동모터이다.First, the configuration of the present invention with reference to FIGS. 1 and 2 will be described. The coil spring of the shaft 2a of the drive gear 2 rotating in engagement with the tape traveling system 50 composed of a plurality of gears 1 is described. The tension portion of (3) is fitted and secures one end (3a) of the coil spring (3) to the upper surface of the drive gear, the other end (3b) of the spring (3) is held on the shaft (4) to rotate The lever (5) is operated in contact with the protrusion (7) formed at the lower end of the (5) so that the upper pinch roller (6) selectively contacts or is spaced apart from the capstan shaft (40) according to the operation of the lever (5). In the drawings, reference numeral 10 denotes a tape, 20 denotes a drum, and 30 denotes a driving motor.
이와 같이 구성된 본 고안의 작용효과는 테이프(10)를 주행시키기 위하여 테이프 주행계(50)를 구동시키면 모터(30)의 구동력을 전달 받은 기어(1a)가 회전하게 됨에 따라 다수개의 기어(1b, 1c, 1d)가 차례로 구동되어 테이프(10)를 로딩시키기 위하여 풀베이스를 전지시키며 이에 따라 테이프는 드럼(20)에 밀착되어져 신호를 재생 또는 녹화할 수 있는 상태가 되며 이와 동시에 기어(1d)와 치합된 구동기어(2)가 회전함에 따라 구동기어(2)의 상면에 코일 스프링의 일단(3a)이 고정된 상태이므로 코일스프링(3)도 같이 회전하게 된다. 그러므로 스프링의 일단(3b)이 레바(5) 하단에 형성된 돌기(70를 밀어주게 되므로 레바(5)는 축(4)을 중심으로 회전하게 되므로 상기 레바(5)의 끝단 상면에 설치된 핀치로울러(6)를 캡스턴축(40)으로 근접시키는 방향으로 이동시키며, 구동기어(2)가 계속회전함에 따라 핀치로울러(6)는 캡스턴축(40)에 밀접하게 닿은 상태에서 사이에 끼인 테이프가 안정되게 주행할 수 있도록 한다. 이때 핀지로울러(6)가 캡스턴축(40)에 닿은 상태에서 구동기어(2)가 약간 더 회전토록하면 핀치로울러(6)가 캡스턴축(40)에 대하여 스프링(3)의 압착력을 가하게 되므로 캡스턴축(40)이 회전하여 테이프를 이동시킬때 핀치로울러(6)가 안정되게 작동한다.The effect of the present invention configured as described above is to drive the tape running system 50 to drive the tape 10 as the gear (1a) received the driving force of the motor 30 is rotated a plurality of gear (1b, 1c and 1d are driven in sequence to charge the full base to load the tape 10. Accordingly, the tape is brought into close contact with the drum 20 so that the signal can be reproduced or recorded. As the meshed drive gear 2 rotates, the one end 3a of the coil spring is fixed to the upper surface of the drive gear 2 so that the coil spring 3 also rotates together. Therefore, one end 3b of the spring pushes the protrusion 70 formed at the bottom of the lever 5, so the lever 5 rotates about the shaft 4, so the pinch roller installed on the upper end of the lever 5 ( 6) in the direction to approach the capstan shaft 40, the pinch roller (6) is in close contact with the capstan shaft (40) as the drive gear (2) continues to rotate to ensure that the tape sandwiched between At this time, if the drive gear 2 is rotated a little more while the pinch roller 6 is in contact with the capstan shaft 40, the pinch roller 6 is spring 3 with respect to the capstan shaft 40. Since the pressing force of the capstan shaft 40 is rotated to move the tape pinch roller (6) operates stably.
이와 같은 상태에서 기기의 동작을 완료하면 모터의 구동방향이 역회전하므로 기어들(1)이 상기와 역방향으로 회전함에 따라 구동기어(2)가 역방향으로 회전하여 캡스턴축(40)으로 부터 이격되는 방향으로 이동하여 레바(5)는 원위치로 돌아온다.In this state, when the operation of the device is completed, the driving direction of the motor is reversely rotated, so that the gears 1 rotate in the reverse direction as described above, so that the driving gear 2 is rotated in the reverse direction to be spaced apart from the capstan shaft 40. The lever 5 returns to its original position by moving in the direction.
상기한 바와 같이 본 고안에 의하면 간단한 구성에 의하여 핀치로울러 구동장치를 작동시킬 수 있도록 함으로서 기기를 소형 경량화 할 수 있으며 구동시 소음을 줄일수 있어 쾌적하게 작동시킬 수 있다.As described above, according to the present invention, the device can be operated by a pinch roller by a simple configuration, thereby making the device compact and light in weight, and reducing noise during driving.
