본 고안은 브이티알 로타리헤드 드럼의 크리닝 장치에 관한 것으로 크리너를 부설하는 탄성 지지대를 헤드 드럼 주위에 설치하고 척력과 복원력을 갖춘 마그네트 부재를 개입시켜 브이티알의 기존 회로와는 별개로 구동이 되면서 헤드 드럼의 주연을 깨끗이 청소가 되도록 하여 사용이 편리하고 기기의 수명과 우수한 성능을 보존토록 함에 있는 것이다.The present invention relates to a cleaning device for a VT rotary head drum, and an elastic support for installing the cleaner is installed around the head drum, and is driven separately from VT's existing circuit through a magnet member having repulsive and resilient force. The main edge of the drum is to be cleaned cleanly so that it is easy to use and preserves the life and excellent performance of the device.

종래에는 크리닝 테이프를 설치하고 로딩상태로 구동시켜 헤드를 포함한 헤드드럼을 닦아주므로서 크리닝 동작시에도 로딩 및 플레이 작동이 되는 것이여서 필요없는 전력소비와 기기의 소모를 갖게 되어 비경제적있었다.In the past, the cleaning tape was installed and driven in a loading state, thereby cleaning the head drum including the head, so that the loading and play operations were performed even during the cleaning operation, thereby causing unnecessary power consumption and device consumption.

본 고안은 이와 같은 종전의 개선점을 보완하여 로딩이나 플레이 기능이 없이도 크리닝 작용만 하도록 하여 크리닝 작동이 간단하고 전력소모를 절약하며 크리너, 교환도 가능하게 하므로서, 신뢰성이 있게 안출한 것으로 이를 첨부 도면에 의하여 설명하면 다음과 같다.The present invention complements these previous improvements, so that the cleaning operation can be performed without loading or playing functions, thereby simplifying the cleaning operation, saving power consumption, and allowing cleaners and exchanges. By explaining it is as follows.

본 고안은 제1도와 같이 기존의 부러쉬 홀더(1)를 이용하여 이에 고정 마그네트(M1)를 설치하고, 이의 대응위치에 유동 마그네트(M2)를 내설한 구동체(2)를 설치하며, 이 구동체(2)의 양쪽 날개편(2-1)에 지지봉(3)을 각각 설치하되 부러쉬 홀더의 전방벽(1-1)을 관통하여 두부(3-1)가 외측에서 걸리게 하였고, 날개편(2-1)과 전방벽(1-1)사이에 위치하도록 지지봉(3)에 크일스프링(4)을 탄력 설치하였으며, 구동체(2)의 전방에 헤드 드럼(8)에 접촉되게 한 호형의 만성 지지대(5)를 설치하여 크리너(6)를 부착시킬 수 있게하고, 그리고 크리너(6)를 밀착시키도록 탄성지지대(5)에 크립(7)을 설치하여 크리너(6)의 교체가 용이하도록 한 것이다.The present invention uses a conventional brush holder (1) as shown in FIG. 1 to install a fixed magnet (M 1 ), and to install a drive body (2) incorporating a floating magnet (M 2 ) in its corresponding position, The supporting rods 3 are respectively installed on both wing pieces 2-1 of the driving body 2, but the head 3-1 is caught from the outside by penetrating the front wall 1-1 of the brush holder. The spring spring 4 is elastically installed on the support rod 3 so as to be located between the piece 2-1 and the front wall 1-1, and the head drum 8 is brought into contact with the front of the driving body 2 in front of the driving body 2. By installing an arc-shaped chronic support 5 to attach the cleaner 6, and installing the creep 7 on the elastic support 5 to bring the cleaner 6 into close contact, the replacement of the cleaner 6 can be performed. It is to facilitate.

그리고, 본 고안은 헤드 드럼(8)의 모터(도시 생략)와 마그네트(M1)(M2)는 VTR의 구동 회로와는 별개의 전원 및 스위치로 온, 오프시키도록 회로를 구성하며, 제 1도와 같이 고정 마그네트(M1)와 유동 마그네트(M2)의 권선방향(점선 화살선)이 서로 상이하여 인가되면 마그네트에 척력이 발생되게 하여 크리너를 갖춘 탄력 지지대(5)가 헤드 드럼(8)에 접촉되고 코일 스프링(4)의 복원력으로 원상되게 구성한 것이다.In addition, the present invention constitutes a circuit such that the motor (not shown) of the head drum 8 and the magnet M 1 (M 2 ) are turned on and off by a power source and a switch separate from the driving circuit of the VTR. As shown in FIG. 1 , when the winding direction (dotted arrow line) of the fixed magnet M 1 and the floating magnet M 2 is applied differently, repulsive force is generated in the magnet so that the elastic support 5 having the cleaner is provided with the head drum 8 ) Is configured to be original by the restoring force of the coil spring (4).

이와같이 된 본 고안은 헤드 드럼을 청소하고저 할때에는 종전의 방법과는 달리 로딩 및 플레이의 기능은 오프시켜 놓은 상태에서 드럼모터 및 마그네트 스위치(도시 생략)을 온시키면 헤드드럼(8)은 회전을 하고 동시에 마그네트(M1)(M2)에 전원이 인가되면서 척력이 생기어 구동체(2)가 헤드 드럼측으로 이동되므로 제 5도에서와 같이 크리너(6)를 헤드드럼(8)에 접촉시켜 그의 주면을 깨끗히 닦아주게 되는 것이다. 그리고 드럼모터 및 마그네트 스위치를 오프시키면 마그네트(M1)(M2)의 척력이 사라지고 코일 스프링(4)의 복원력으로 제 3도에서와 같이 헤드 드럼(8)으로부터 크리너(6)가 떨어지고, 헤드 드럼(8)도 회전을 정지하게 되는 것이다.When the head drum 8 and the magnetic switch (not shown) are turned on while the loading and play functions are turned off, the head drum 8 stops rotating when the head drum is cleaned. At the same time, as the power is applied to the magnets M 1 and M 2 , the repulsive force is generated, and the driving body 2 moves to the head drum side. As shown in FIG. 5, the cleaner 6 is brought into contact with the head drum 8. It is to clean his main surface. When the drum motor and the magnet switch are turned off, the repulsive force of the magnets M 1 and M 2 disappears, and the cleaner 6 falls from the head drum 8 as shown in FIG. 3 by the restoring force of the coil spring 4, and the head The drum 8 also stops rotating.

이와 같이 본 고안은 VTR의 로딩 기능이나 플레이 기능의 구동과는 별개로 작동되는 마그네트를 개재하여 크리너를 헤드 드럼에 다았다 떨어졌다 하도록 하여 헤드 드럼을 청소하게 되어 사용이 간편 용이하고, 기존의 VTR기능을 이용하지 않아 손상을 예방하며 전력 손실도 절감시키므로서 신뢰성과 경제성이 있는 고안이다.As such, the present invention cleans the head drum by dropping the cleaner on the head drum via a magnet operated separately from the driving function of the loading function or the play function of the VTR. It is designed to be reliable and economical by preventing the damage and reducing the power loss by not using the function.
