본 고안은 VTR의 드럼 헤드크리닝장치에 관한 것으로, 특히 VTR의 PLAY전, 후에 폴 베이스의 상승, 하당에 따른 레버의 연동작용에 의하여 헤드를 크리닝시킬 수 있도록 함은 물론, 2중의 완충작용이 이루어지도록한 헤드 크리닝장치에 관한 것이다.The present invention relates to a drum head cleaning device of the VTR, and in particular, to allow the head to be cleaned by the interlocking action of the lever according to the raising and lowering of the pole base before and after the play of the VTR, as well as a double buffering effect. It relates to a head cleaning device to be built.

종래 다수의 헤드 크리닝장치가 안출된 바 있으나, 대부분 구조가 복잡하여 원가상승의 요인이 되는 단점을 갖는 것이었고 또한, 폴 베이스의 작동에 따른 레버의 연동접촉에 의해 스폰지제의 크리너를 드럼헤드에 접촉, 분리되게 하는 것이 있으나, 이는 이젝트시나 파우어 오프시에도 크리너가 드럼에 계속 밀착 접촉되어 있는 것이어서, 스폰지가 압축 편심되고 차후 작동시에는 소음과 불균일한 접촉력등으로 인하여 헤드에 악영향을 미치게되는 문제점을 갖는 것이었다.Although a number of head cleaning devices have been proposed in the related art, most of them have a disadvantage in that the structure is complicated and causes a cost increase. Also, a sponge cleaner cleaner is applied to the drum head by interlocking contact of the lever according to the operation of the pole base. Although the contactor may be separated, this is because the cleaner keeps in close contact with the drum even during ejection or power-off, so that the sponge is compressed and eccentric and adversely affects the head due to noise and uneven contact force during subsequent operation. It was to have.

본 고안은 상기 종래의 단점과 문제점을 해결하고자 안출된 것인바, 간단한 구조로서 원가상승 요인을 배제 함은 물론 PLAY전, 후시에만 헤드를 크리닝시켜 헤드에 무리가 가지 않도록 하기 위하여, 폴 베이스의 상승, 하강에 다른 FE 홀더의 연동에 따라 움직이도록 두개의 상, 하측 레버를 토션스프링으로 연결하고 상측레버 단부에는 스폰지제의 크리너를 또 다른 스프링으로 연결시켜 헤드에 접촉, 분리되도록 한 것인 바, 이하 첨부한 도면에 의거하여 본 고안을 상세히 설명하면 다음과 같다.The present invention is devised to solve the above disadvantages and problems, the simple structure of eliminating the cost increase factor, as well as cleaning the head only before and after the PLAY, so that the head does not go to the rise of the pole base, To connect the two upper and lower levers with torsion springs to move according to the linkage of other FE holders on the lower side, and the sponge cleaners connected to another spring at the upper lever ends to contact and separate the heads. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

드럼(1)에 근접하여 상승, 하강되는 폴 베이스(2)와, 폴 베이스(2)에 접촉하여 정, 역회동되는 FE홀더(3)를 갖는 것에 있어서, 상기 FE홀더(3)와 접촉하여 정, 역회동되도록 데크판(4)에 상, 하측레버(5)(6)를 핀(8)으로써 회동 용기하게 연결하고, 핀(7)에는 토션스프링(8)을 결합하여 토션스프링(8)의 양단부가 상기 상, 하측 레버(5)(6)에 걸려지도록하며, 상측레버(5)의 일단부에 스폰지제의 헤드크러너(9)를 부착연결하되, 상측레버(5)의 일단부에는 삽입홈(10)을 형성하여 그 삽입홈(10)의 내부 일측면에 스프링(11)으로 연결한 지지봉(12)을 입설하고, 지지봉(12)에는 헤드크러너(9)를 회전 용이하게 결합하여 상기 폴베이스(2)의 상승, 하강시 FE홀더(3)의 정, 역회동에 따라 헤드크러너(9)가 드럼 헤드(13)에 탄력적으로 접촉, 분리되도록 한 것이다.The pole base 2 which is raised and lowered close to the drum 1, and the FE holder 3 which is forward and reverse rotated in contact with the pole base 2, is in contact with the FE holder 3 The upper and lower levers 5 and 6 are pivotally connected to the deck plate 4 by the pins 8 so as to rotate forward and reverse, and the torsion springs 8 are coupled to the pins 7 by the torsion springs 8. ) Both ends of the upper and lower levers (5) (6) to be hooked, and one end of the upper lever (5) is attached to the sponge head runner (9), one end of the upper lever (5) An insertion groove 10 is formed in the part, and a support rod 12 connected to the inner side of the insertion groove 10 by a spring 11 is inserted therein, and the head rod 9 is easily rotated on the support rod 12. When the pole base 2 is raised and lowered, the head cruner 9 elastically contacts and separates the drum head 13 according to the forward and reverse rotation of the FE holder 3.

상기한 바와 같이 된 본 고안은, PLAY시 폴 베이스(2)가 상승하면 폴 베이스(2)는 제 3 도의 (b)도와 같이 FE홀더(3)를 반시계방향으로 밀게되고, FE홀더(3)의 회동으로 FE홀더(3)는 하측레버(6)를 시계방향으로 회동시키게 되며 이때 상측레버(5) 역시 시계방향으로 회동하면서 토션스프링(8)의 양단부는 핀(7)측으로 약간 압축된다.According to the present invention as described above, when the pole base 2 rises during play, the pole base 2 pushes the FE holder 3 counterclockwise as shown in FIG. 3 (b), and the FE holder 3 ), The FE holder 3 rotates the lower lever 6 clockwise. At this time, the upper lever 5 also rotates clockwise, and both ends of the torsion spring 8 are slightly compressed toward the pin 7 side. .

이와 동시에, 헤드 크리너(9)가 헤드 드럼(1)에 밀착 접촉되고 스프링(11)은 약간 압축되면서 VTR의 PLAY 동작모드에 따라 헤드크리닝이 진행되는 것이다.At the same time, the head cleaner 9 is in close contact with the head drum 1 and the spring 11 is slightly compressed to perform head cleaning according to the PLAY operation mode of the VTR.

한편, PLAY가 완료되고 폴 베이스(2)가 하강하면 상기의 역작용에 의거하여 헤드 크리너(9)는 헤드 드럼으로부터 분리되고 헤드크리닝작용은 완료된다.On the other hand, when the PLAY is completed and the pole base 2 is lowered, the head cleaner 9 is separated from the head drum based on the above reaction, and the head cleaning operation is completed.

이상에서와 같이 본 고안은 간단한 구조로써 폴 베이스의 상승, 하강에 따라서만 헤드 크리닝이 실시되게하므로, 또한 2개의 스프링에 의해 탄력을 부여하여 헤드크리너의 드럼헤드에 대한 밀착압력이 자동조절되게 하므로써, 원가절감에 기여하고 크리닝시 헤드에 악영향을 미치지않게하며 소음제거와 아울러 제품의 수명연장에 기여하는 유용한 고안이다.As described above, the present invention has a simple structure, so that the head cleaning is performed only according to the rise and fall of the pole base, and also by providing elasticity by two springs, the adhesion pressure of the head cleaner to the drum head is automatically adjusted. It is a useful design that contributes to cost reduction, does not adversely affect the head during cleaning, removes noise and extends the life of the product.
