본 고안은 픽업바늘의 위치를 디스크레코오드 흠의 상태 속도에 따라 변화시켜 주는 비디오디스크 플레이어의 암스트레쳐(arm stretcher)에 대한 것이다.The present invention is directed to an arm stretcher of a video disc player that changes the position of the pickup needle according to the speed of the disc record defect.

종래의 암스트레쳐는 제4도에 도시된 바와같이 케이스내에 원봉형의 영구자석을 고정부착하여, 일부분이 보디에 적정간격을 갖게 격설된 2개의 원판형 탄성판을 관통되게 설치한 신장축이 연설된 원통형 솔레노이드코일(SOLENOIDCOIL)에 의해 감삽되도록 하였다.In the conventional arm stretcher, as shown in FIG. 4, an elongated shaft having a disc-shaped permanent magnet fixedly attached to a case and a portion of the arm stretcher penetrating two disc-shaped elastic plates spaced at an appropriate distance from the body is installed. It was allowed to be subtracted by a speeched cylindrical solenoid coil (SOLENOIDCOIL).

그러나 이는 구조상 영구자석과 솔레노이드코일의 중심을 맞추기가 매우 어렵고 전체적인 구조가 복잡하여 작업공정이 까다롭고 불량이 많이 발생되며 공진이 오래 지속될 경우 전자석에 연결된 코일이 단선되는 예가 많은 점등의 결점이 있었다.However, due to the structure, it is difficult to center the permanent magnet and solenoid coil, and the overall structure is complicated, so that the work process is complicated, and a lot of defects are generated.

본 고안은 이와 같은 점을 해결하기 위해 원통형의 솔레노이드를 고정되게 설치하고 신장축에 영구자석을 부착하여 영구자석이 솔레노이드코일내에서 공진되도록 하므로 제작이 간편하도록 고안한 것으로 첨부도면에 의거 상술하면 다음과 같다.In order to solve this problem, the present invention is designed to simplify the installation of the cylindrical solenoid and to fix the permanent magnet on the extension shaft so that the permanent magnet is resonated in the solenoid coil. Same as

영구자석(3)이 부착된 호울디(2)를 선단에 착설한 신장축(1)을 본체(4)와 이와 관착된 탄성판(5)을 관통되게 하여 원봉형의 영구자석(6)을 부착하고, 이 영구자석이(6)고정판(7)에 착설된 원통형의 솔레노이드코일(8)내에 감삽되도록하며, 본체(4)와 고정판(7)의 양측에 스프링(9)(9')을 탄력 설치하여서 된 것이다.The rod-shaped permanent magnet (6) attached to the permanent magnet (3) attached to the front end of the expansion shaft (1) through the main body (4) and the elastic plate (5) connected to the permanent magnet (6) The permanent magnet (6) is inserted into the cylindrical solenoid coil (8) mounted on the fixed plate (7), and springs (9) (9 ') are provided on both sides of the main body (4) and the fixed plate (7). It was made by installing elasticity.

미설명부호 "10"은 카아트릿지 지지편이고 "11"은 종래제품의 영구자석이며 "12"는 전자석이고 "13, 13' "는 원판형 탄성판이며, 이와 같이된 본 고안은 솔레노이드코일(8)을 고정판(7)으로 고정되게 설치하고, 신장축(1)에 부착된 영구자석(6)을 이에 감삽되어 솔레노이드코일(8)의 작동에 따라 공진되도록 하였기 때문에 영구자석(6)이 단선될 염려가 전혀 없으며, 구조가 간단하고 이들의 중심을 맞추기가 용이하여 제작 공정이 간편하며, 신장축(1)의 선단이 본체(4)의 전면부를 관통되게 하였으므로 하나의 탄성판(5)만으로도 텐션을 충분히 유지할 수 있게되어, 종래와같이 탄성판을 두개씩 사용할 필요가 없으며 본체(4)의 양측을 스프링(9)(9')으로 탄력 설치하였기 때문에 장기간 사용해도 본체(4)의 전후 이동이 순조롭게 되는 것이다.Reference numeral "10" is a caratridge support piece, "11" is a permanent magnet of a conventional product, "12" is an electromagnet, "13, 13" "is a disk-shaped elastic plate, the present invention is a solenoid coil ( 8) is fixed to the fixed plate (7), and the permanent magnet (6) attached to the expansion shaft (1) is interpolated therein so as to resonate with the operation of the solenoid coil (8), so that the permanent magnet (6) is disconnected There is no concern about it, and the structure is simple and easy to center them, so the manufacturing process is simple. Since the tension can be sufficiently maintained, there is no need to use two elastic plates as in the prior art, and since both sides of the main body 4 are elastically installed with the springs 9 and 9 ', the front and rear movement of the main body 4 can be maintained even if used for a long time. It will be smooth.

이와 같이 본 고안은 종래에 비해 전체적인 구조가 간단하고, 솔레노이드 코일과 영구자석의 중심을 맞추기가 매우 용이하므로 작업 공정이 간편하고, 부품수가 감소되어, 제조단가가 절감되는 등의 효과를 얻을 수 있는 것이다.As such, the present invention has a simpler overall structure than the conventional one, and is very easy to center the solenoid coil and the permanent magnet, thereby simplifying the work process, reducing the number of parts, and reducing the manufacturing cost. will be.
