Abstract

본 발명은 DVD(Digital Versatile Dise)플레이어에 사용되는 트윈렌즈형 액츄에이터(Twinlens Type Acuator)에 관한 것으로, 더욱 상세하게는 트윈렌즈형 액츄에이터의 대물렌즈(Objective Lens)를 한쪽에서 4개의 와이어로 지지하는 포커스(Focus) 및 트래킹(Tracking)방향의 구동이 가능토록 하므로서 DVD 뿐만 아니라 CD플레이어용으로도 사용이 가능하도록 한 CD와 DVD플레이어의 겸용이 가능한 트윈렌즈형 액츄에이터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a twin lens type actuator used in a DVD (Digital Versatile Dise) player, and more particularly to a twin lens type actuator that supports an objective lens of a twin lens type actuator by four wires from one side And to a twin lens type actuator capable of being used both as a CD and a DVD player so that it can be used for a CD player as well as a DVD by driving a focus and a tracking direction.

이를 위해 본 발명은 하나의 렌즈홀더(100)에 DVD용과 CD용으로된 2개의 대물렌즈(50)(60)를 설치하고, 상기 렌즈홀더는 4개의 와이어로 구성된 서스펜션(90)을 통하여 고정홀더(40)에 지지시켜서 된 것이다.To this end, two objective lenses 50 and 60 for DVD and CD are provided in one lens holder 100, and the lens holder is fixed to a fixed holder 90 through a suspension 90 composed of four wires. (40).
