Abstract

본 발명은 피에조 소자를 이용한 컴팩트 디스크 장치에 관한 것으로, 종래의 와이어 스프링에 의해 지지되는 대물렌즈는 외부의 진동에 민감하여 컴팩트 디스크 장치가 진동을 받게 되면 음을 잘 들을 수 없게 되는 문제가 있었다.The present invention relates to a compact disk device using a piezo element, and the objective lens supported by the conventional wire spring is sensitive to external vibration, so that when the compact disk device is subjected to vibration, the sound cannot be heard well.

본 발명은 예시도면 제3도와 같이 빔 스플리터(20)와 인접된 부위에 피에조 소자(18)와 대물렌즈(12)를 설치하되 대물렌즈(12)는 움직이지 않도록 고정시키고, 피에조 소자(18)에 가해진 전류의 전압으로 빔 스플리터(20)와 접촉되어 빔 스플리터(20)가 가운데를 중심으로 움직이므로서 레이저 다이오드(16)에 맺혀진 초점을 조절하도록 한 것이다.According to the present invention, the piezoelectric element 18 and the objective lens 12 are installed at a portion adjacent to the beam splitter 20 as shown in FIG. 3, but the objective lens 12 is fixed to not move and the piezoelectric element 18 is fixed. The beam splitter 20 is brought into contact with the beam splitter 20 by the voltage of the current applied thereto, so that the beam splitter 20 moves about the center to adjust the focus of the laser diode 16.

따라서, 본 발명은 컴팩트 디스크 장치에 약간의 진동이 가해져도 음악을 잡음없이 들을 수 있는 효과가 있다.Therefore, the present invention has the effect of allowing music to be heard without noise even when a slight vibration is applied to the compact disc device.

컴팩트 디스크 장치에 있어서, 빔 스플리터(20)의 인접된 부위에 피에조 소자(18)와 대물렌즈(12)를 설치하되, 대물렌즈(12)는 움직이지 않도록 고정되고, 피에조 소자(18)는 레이저 다이오드(16)와 연결되어 레이저 다이오드(16)에 맺혀진 상의 판독으로 피에조 소자(18)에 전류를 가하여 피에조 소자(18)의 팽창으로 빔 스플리터(20)의 각도가 조절되는 것을 특징으로 하는 피에조 소자를 이용한 컴팩트 디스크 장치.In the compact disk apparatus, the piezoelectric element 18 and the objective lens 12 are installed in adjacent portions of the beam splitter 20, but the objective lens 12 is fixed so as not to move, and the piezoelectric element 18 is lasered. Piezo, characterized in that the angle of the beam splitter 20 is adjusted by the expansion of the piezoelectric element 18 by applying a current to the piezoelectric element 18 by reading the image connected to the diode 16 and the image attached to the laser diode 16. Compact disc device using the device. ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
