본 고안은 마이크로 플로피 디스크에 관한 것으로 특히 스핀들 모터의 보조구동축이 접촉되는 상부쉘의 개량된 구조에 관한 것이다.The present invention relates to a micro floppy disk, and more particularly to an improved structure of the upper shell in which the auxiliary drive shaft of the spindle motor is in contact.
마이크로 플로피 디스크는 제1도 및 제2도에서와 같이 상부쉘(1)과 하부쉘(2)내에 자기디스크(3)가 센터코아(10)에 의해 지지되어 있으며, 디스크 보호용 부직포(6), (7)와 기록보호용 셔터(8)가 결합되어 있다.As shown in FIGS. 1 and 2, a micro floppy disk has a magnetic disk 3 supported by a center core 10 in an upper shell 1 and a lower shell 2, and a disk protection nonwoven fabric 6, (7) and the recording protection shutter 8 are combined.
특히, 센터코아(10)에는 스핀들 모터(도시되지 않음)의 모터축(13)이 끼워져서 회전시켜주는 축홀(11)과 보조구동축(14)의 축홀(15)이 형성되어서, 센터코아(10)가 헛돌림없이 회전되어져 디스크(3)상의 정보를 기록 또는 재생하게 되어 있다.In particular, the center core 10 is formed with a shaft hole 11 to which the motor shaft 13 of the spindle motor (not shown) is inserted and rotated, and the shaft hole 15 of the auxiliary driving shaft 14 is formed. ) Is rotated without retraction so that information on the disc 3 can be recorded or reproduced.
그런데, 제2도에서 보는 바와 같이, 보조구동축(14)이 상부쉘(1)의 센터플레이트(12)에 접촉되면서 회전시에 분진 발생이나 소음을 발생시키므로 미세한 전류로 기록이 변환되는 자기디스크에 분진이 발생할 경우 원하는 수치가 기록되거나 재생될 수는 없게 된다.However, as shown in FIG. 2, since the auxiliary drive shaft 14 is in contact with the center plate 12 of the upper shell 1 and generates dust or noise during rotation, the magnetic disk is converted into a fine current. If dust does occur, the desired value cannot be recorded or reproduced.
특히, 모터축(13)이 제자리에서 회전하므로 분진이나 소음발생이 적은 반면 보조구동축과 상부쉘의 회전 마찰력은 무시할 수 없을 정도로 큰 것이다.In particular, since the motor shaft 13 rotates in place, less dust or noise is generated while the rotational frictional force between the auxiliary drive shaft and the upper shell is insignificant.
이에 본 고안에서는 스핀들 모터의 보조 구동축이 접촉되는 위치에 요홈을 형성시켜서 서로 접촉되지 않게 하여 종래의 문제점을 해소한 것이다.Therefore, the present invention solves the conventional problem by forming a groove in a position where the auxiliary drive shaft of the spindle motor is in contact with each other.
이를 첨부도면과 함께 상술한다.This will be described in detail with the accompanying drawings.
제3도에서와 같이, 본 고안은 스핀들 모터의 보조구동축(14)이 접촉되는 상부쉘(1)의 내면에 원형의 요홈(16)을 형성시켜서, 센터코아(10)가 회전되더라도 보조구동축(14)이 상부쉘(1)에 접촉되지 않도록 구성시킨 것이다.As shown in FIG. 3, the present invention forms a circular groove 16 on the inner surface of the upper shell 1 to which the auxiliary drive shaft 14 of the spindle motor contacts, so that the auxiliary drive shaft (even if the center core 10 is rotated) 14) is configured not to contact the upper shell (1).
이때 원형요홈(16)은 보조구동축(14)보다 직경이 커서 센터코아(10)의 미동에도 접촉되지 않는 여유가 있게 하며, 원형요홈(16)으로 인한 상부쉘(1)의 강성이 해쳐지지 않을 깊이로 형성시킨다.At this time, the circular groove 16 has a larger diameter than the auxiliary drive shaft 14, so that the circular groove 16 can not be touched even by the fine motion of the center core 10, and the rigidity of the upper shell 1 due to the circular groove 16 is not impaired. Form to depth
상기와 같이 본 고안이 적용된 마이크로 플로피 디스크는 보조구동축과 상부쉘의 마찰에 의한 분진이나 소음의 염려가 없고, 이 때문에 제품의 신뢰도를 향상시킬 수 있는 효과가 있다.As described above, the micro floppy disk to which the present invention is applied has no fear of dust or noise due to friction between the auxiliary drive shaft and the upper shell, and thus, the reliability of the product can be improved.
