Abstract

본 발명은 광 디스크 플레이어의 틸트조정장치에 관한 것으로서, 압전소자를 이용하여 디스크의 높낮이를 조절함에 따라 틸트가 조정되도록 구조를 변경하여 부품수를 줄임에 따른 제작비의 절감과 함께 신속하고 정확한 틸트조정이 가능하도록한 것이다.The present invention relates to a tilt adjustment apparatus of an optical disc player, and by changing the structure so that the tilt is adjusted by using a piezoelectric element to adjust the height of the disc, a quick and accurate tilt adjustment with a reduction in the manufacturing cost due to the reduction of the number of parts. This is what made it possible.

이를 위해 본 발명은 데크베이스(1)에 안내레일(2)을 따라 슬라이딩 가능하도록 설치된 픽업(3)과, 상기 픽업에 부착되어 재생시 디스크와 픽업(3)의 거리를 센싱하는 센서(6)와, 상기 센서에서 센싱된 값과 기 설정된 값의 차를 제어부를 통해받아 전계를 발생시키는 전계발생부와, 상기 데크베이스(1)에 중심선상을 기점으로 회동가능하게 설치되어 턴테이블(8)이 축결합된 스핀들모터(9)를 지지하는 회동판(7)과, 상기 회동판의 회동기점과 직교되는 중심선상에 위치되도록 데크베이스(1)와 회동판(7) 사이의 양측에 설치되어 전계발생부에서 발생된 전계를 받아 수직으로 팽창되는 압전소자(10)로 구성하여서 된 것이다.To this end, the present invention is a pickup (3) installed on the deck base (1) to be slidable along the guide rail (2), and the sensor (6) attached to the pickup to sense the distance between the disk and the pickup (3) during playback And an electric field generating unit for generating an electric field by receiving a difference between the value sensed by the sensor and a predetermined value through a control unit, and the turntable 8 being rotatably installed on the deck base 1 starting from a center line. Rotating plate (7) for supporting the spindle motor (9) coupled to the shaft, and installed on both sides between the deck base (1) and the rotating plate (7) so as to be located on the center line orthogonal to the rotational starting point of the rotating plate It consists of a piezoelectric element 10 that is expanded vertically in response to the electric field generated by the generator.
