본 고안은 브이씨알(VCR)의 회전실린더 장치에 관한 것으로, 특히 하부실린더의 패턴을 설치하여 모터 및 회전트랜스 신호선을 줄임으로써 작업성을 개선하고, 성능을 향상시키도록 한 브이씨알의 회전실린더 장치에 관한 것이다.The present invention relates to a rotary cylinder device of VCR (VCR), and in particular, to install the pattern of the lower cylinder to reduce the motor and rotation transformer signal line to improve the workability and improve the performance of the rotary cylinder device It is about.

종래의 회전실린더는 제1도 및 제2도에 나타낸 바와 같이, 상부실린더 장치(11)와 하부실린더 장치(12)로 결합하여 형성된다.The conventional rotary cylinder is formed by combining the upper cylinder device 11 and the lower cylinder device 12, as shown in FIG. 1 and FIG.

상기 상부살린더 장치(11)는 상부실린더, (11a)의 하단에 회전헤드(20)가 설치된다.The upper cylinder device 11 is provided with a rotating head 20 at the lower end of the upper cylinder (11a).

상기 하부실린더 장치(12)는 상부에 플랜지장치(25)와 고정트랜스(14)가 설치되고, 하부에 베어링(22)와 와셔(27) 및 링칼라(26)가 설치된다.The lower cylinder device 12 is provided with a flange device 25 and a fixed transformer 14 on the upper side, and a bearing 22, a washer 27, and a ring collar 26 on the lower side.

또한 상기 플랜지장치(25)는 플랜지(25a)의 저부에 회전트랜스(13)가 결합되고, 중앙홀에 샤프트(17)가 끼워진다.In addition, the flange device 25 is coupled to the rotary transformer 13 at the bottom of the flange (25a), the shaft 17 is fitted into the central hole.

또 모터장치는 회전모터(16)와 고정모터(15)를 결합하여 구성된다.In addition, the motor device is configured by combining the rotary motor 16 and the fixed motor (15).

이러한 종래의 회전실린더 장치는 세트상태에서 비디오테이프를 삽입한 다음 로딩시키면, 메인기판으로부터 직류전압을 인가받아 회전실린더 장치가 회전하게 된다. 이때, 휘도/칼라 동작은 기록시 휘도/칼라회로, 고정트랜스 FPC(Flexible Printed Circuit board)(14a), 고정트랜스(14), 회전트랜스(13) 및 회전헤드(20)로 신호가 전달된다. 재생시에는 상기 동작의 역순으로 전달된다. 한편, 모터계는 서보(serbo) 회로에서 직류전압을 인가받아 연결와이어, 모터콘넥터(15a) 및 고정모터(15)로 직류전압이 전달되어 회전모터(16)가 회전하게 된다.In the conventional rotary cylinder device, when the video tape is inserted and then loaded in a set state, the rotary cylinder device is rotated by receiving a DC voltage from the main board. In this case, the luminance / color operation is transmitted to the luminance / color circuit, the fixed transformer FPC 14a, the fixed transformer 14, the rotation transformer 13, and the rotation head 20 during recording. At the time of reproduction, the operation is transmitted in the reverse order. On the other hand, the motor system receives a DC voltage from the servo circuit (serbo), the DC wire is transmitted to the connection wire, the motor connector 15a and the fixed motor 15 to rotate the rotating motor 16.

그러나 이러한 종래의 기술은 휘도/칼라에 연결된 고정트랜스 FPC(14a)와 모터계에 연결된 모터콘넥터(15a)가 각각 분리되어 있으므로 조립작업이 까다로운 단점이 있었으며, 휘도/칼라에 연결된 고정트랜프 FPC(14a)의 길이가 길어 주변회로 및 자성체에 의하여 노이즈가 발생하는 문제점이 있었다.However, this conventional technique has a disadvantage in that the assembly work is difficult since the fixed transformer FPC 14a connected to the luminance / color and the motor connector 15a connected to the motor system are separated, and the fixed transformer FPC (connected to the luminance / color) Since the length of 14a) is long, noise is generated by the peripheral circuit and the magnetic material.

또한 고정모터(15)를 별도로 조립하므로 회전실린더의 크기가 커지고, 이로 인하여 데크 사이즈도 커져 소형 데크의 개발에 장애가 되는 결점이 있었으며, 고정모터(15)의 코일단선 및 쇼트불량시 고정모터(15)를 교체하여야 하므로 원가절감에 불리한 단점이 있었다.In addition, since the fixed motor 15 is assembled separately, the size of the rotating cylinder is increased, and thus the deck size is also increased, which has a drawback in the development of a small deck, and the fixed motor 15 when the coil is disconnected or short-circuited. ), There was a disadvantage in cost reduction.

또 고정트랜스(14)와 휘도/칼라신호전달은 고정트랜스 FPC(14a)를 사용하므로 주변의 노이즈에 의하여 비트(Beat) 발생, 화면거침 및 크로스 토크(Cross-Talk)가 증가하는 문제점이 있었으며, 휘도/칼라신호계와 모터계의 콘넥터가 별도로 구비되어야 하므로 신기술인 노 하니스(No Barness) 타입의 데크에 적용시키기 불가능한 문제점이 있었다.In addition, since the fixed transformer 14 and the luminance / color signal transmission use the fixed transformer FPC 14a, there is a problem in that beat generation, screen roughness, and cross talk are increased due to ambient noise. Since the connectors of the luminance / color signal system and the motor system have to be provided separately, there is a problem that it is impossible to apply the new technology to the deck of the No Barness type.

따라서 본 고안은 상기한 문제점을 해소하기 위한 것으로, 그 목적은 첫째, 구조를 간단히 하고, 둘째, 코일단선 및 쇼트 등의 불량시 고정모터의 코어만 교체하도록 하여 원가를 절감하며, 셋째, 회전실린더의 크기를 줄여 소형화가 가능하도록 하는 브이씨알의 회전실린더 장치를 제공하는 데 있다.Therefore, the present invention is to solve the above problems, the purpose of the first is to simplify the structure, and second, to reduce the cost by replacing only the core of the fixed motor in the case of failure, such as coil break and short, third, rotating cylinder It is to provide a rotary cylinder device of V-Cal to reduce the size of the cylinder to enable miniaturization.
