본 고안은 플로피 디스크 드라이브에 있어서 스탭 모터의 구동시 정확한 스탭 앵글과 풀리의 떨림을 방지하여 액튜에이터(ACTUATOR)의 활동을 정확하게 유지할 수 있게된 플로피 디스크 드라이브(FLOPPY DISK DRIVE)스탭 모터의 진동흡수 장치에 관한 것이다.The present invention is a floppy disk drive in the vibration absorbing device of the floppy disk drive (FLOPPY DISK DRIVE) step that can maintain the activity of the actuator (actuator) accurately by preventing the shaking of the correct step angle and pulley when driving the step motor It is about.

종래의 플로피 디스크 드라이브에 있어서는 스탭 모터 자체를 개조하여 하이브라이드(Hybride)형, 팬케이크(PAN CAKE)형으로 사용되어 왔으나 이는 근본적으로 풀리의 떨림은 해결되지 않아 고밀도의 플로피 디스크 드라이브를 제작하는데 많은 결점이 있었다.In the conventional floppy disk drive, the step motor itself has been modified to be used as a hybrid type and a pan cake type. However, this is fundamentally used to produce a high density floppy disk drive because the vibration of the pulley is not solved. There was this.

본 고안은 이와같은 종래의 결점을 해결하기 위하여 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 설명하면 다음과 같다.The present invention has been devised to solve such a conventional drawback and the construction and operation effects by the accompanying drawings are as follows.

플로피 디스크 드라이브 몸체(1)면에 풀리(2)가 연결된 스텝모터(3)와 헤드케리지(4)를 장착하여 스틸밴드(5)로 연결시킨것에 있어서 스탭모터(3)에 연결된 풀리(2)의 일면에 밀착되게 스프링(6)이 고정된 진동방지대(7)가 몸체(1)에 부착되어 스크류(8)로 조정될 수 있게 조립 구성되어진 것이다.Step motor (3) and head carriage (4) connected to the pulley (2) on the surface of the floppy disk drive body (1) and attached by a steel band (5) in the pulley (2) connected to the step motor (3) The vibration preventing member 7 fixed with the spring 6 to be in close contact with one side is attached to the body 1 and is configured to be adjusted by a screw 8.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

플로피 디스크 드라이브에 있어서 스탭모터(3)의 정확한 스탭 앵글에 의해 회전운동이 헤드케리지(4)의 직선운동으로 변화되어 디스크상의 각 트랙을 정확하게 위치하여 재생과 기록의 데이타를 소화할 수 있는 능력이 거의 100% 유지되어야 고밀도 트랙의 플로피 디스크 드라이브를 개발하는데 크게 기여할 수 있으므로 스탭모터(3)의 구동시 정확한 스탭 앵글과 풀리(2)의 떨림을 방지하여 액투에이터의 활동을 정확하게 유지할 수 있도록 해야하기 때문에 본원은 스탭모터(3)에 의해 풀리(2)가 회전시에 몸체(1)면에 부착되어 스크류(8)로 조정될 수 있게 고정된 진동 방지대(7)와 풀리(2)의 접촉면이 정확하게 접촉하여 풀리(2)의 떨림을 스프링(6)이 밀면서 최대한 작용하여 자체 떨림을 억제시키게 되므로써 플로피 디스크 드라이브의 고밀도 성능에 크게 영향을 미쳐 고가의 품질을 유지할 수 있게된 것이다.In the floppy disk drive, the exact step angle of the step motor 3 causes the rotational motion to be changed to the linear motion of the head carriage 4 so that each track on the disc can be precisely positioned to digest and reproduce the data of playback and recording. It should be maintained almost 100%, which can greatly contribute to the development of high density track floppy disk drive. Therefore, it is necessary to prevent accurate step angle and vibration of the pulley (2) when driving the step motor (3) so that the actuator can be maintained accurately. Therefore, the present application provides a contact surface between the anti-vibration table 7 and the pulley 2 fixed to the pulley 2 by the step motor 3 so that the pulley 2 is attached to the body 1 surface at the time of rotation and adjusted by the screw 8. As the spring (6) pushes the vibration of the pulley (2) to the correct contact and suppresses its own vibration, it greatly increases the high density performance of the floppy disk drive. It had a face that would be able to maintain high quality.
