Abstract

본 발명은 광픽업의 대물렌즈 구동부 지지장치에 관한 것으로서, 대물렌즈 구동부의 지지상태가 안정되고, 대물렌즈 구동부가 평형상태를 유지하면서 구동되도록 개선된 광픽업의 대물렌즈 구동부 지지장치를 제공한다. 본 발명은, 대물렌즈가 탑재되며 그 몸체에 수평, 수직구동코일이 마련된 대물렌즈 구동부와, 상기 대물렌즈 구동부가 지지되는 베이스를 구비하여 된 광픽업의 대물렌즈 구동부 지지장치에 있어서, X자로 교차되며 상기 대물렌즈 구동부 몸체의 양측에 그 일단이 각각 한쌍씩 힌지고정되는 두쌍의 지지부재와, 상기 두쌍의 지지부재의 타단을 상기 베이스에 각각 회동 및 직선이동 가능하게 지지하는 제1지지수단과, 상기 두쌍의 지지부재의 교차부를 회동 및 승강가능하게 지지하는 제2지지수단을 구비하여 구성된다. 제3도The present invention relates to an objective lens driver supporting apparatus for an optical pickup, and provides an objective lens driver supporting apparatus for an optical pickup, in which the supporting state of the objective lens driving unit is stabilized and the objective lens driving unit is driven while maintaining an equilibrium state. The present invention provides an objective lens driving unit supporting an optical pickup having an objective lens mounted thereon and having a horizontal and vertical driving coil provided on a body thereof, and a base on which the objective lens driving unit is supported. And two pairs of supporting members each having one end hinged and fixed to both sides of the objective lens driver body, and first supporting means for supporting the other ends of the two pairs of supporting members to be rotated and linearly moved to the base, respectively; And second supporting means for supporting the intersections of the two pairs of supporting members to be rotatable and liftable. Third degree
