Installation of a pickup guide shaft for an optical disc driver that can easily adjust the height of the shaft, reduce the number of parts, reduce production costs, and minimize the jitter when reading signals recorded on the optical disc. It's about structure.
일반적으로, 광디스크상에 기록되어 있는 데이터(DATA)나 그 광디스크상에 상기 데이터를 기록하는 광디스크 드라이버는 상기 도 1에 도시된 바와 같이 상기 광디스크(1)를 장착하여 회전구동하는 스핀들모터(2)가 설치된 픽업베이스(3)가 형성되어 있고, 그 픽업베이스(3)에는 상기 광디스크상(1)에 데이터를 리드하거나 그 광디스크상(1)에 데이터를 기록하는 광픽업부(4)가 설치되어 있다.In general, the data DATA recorded on the optical disk or the optical disk driver for recording the data on the optical disk is a spindle motor 2 which rotates and drives the optical disk 1 as shown in FIG. Is provided with a pickup base 3 provided with an optical pickup section 4 for reading data on or recording data on the optical disc 1. have.
그 광픽업부(4)는 레이저광을 집광하여 상기 광디스크(1)에 조사할 수 있는 픽업렌즈(4a)가 설치된 픽업본체가 설치되어 있고, 그 픽업본체는 상기 광디스크(1)의 중심부와 외주변을 가로질러 가이드될 수 있는 픽업 가이드 샤프트(4b)에 설치되며, 그 픽업 가이드 샤프트(4b)는 상기 픽업베이스(3)에 모울드 또는 프레스로 설치고정하게 된다.The optical pickup unit 4 is provided with a pickup main body provided with a pickup lens 4a for condensing laser light and irradiating the optical disc 1, and the pickup main body is provided at the center and the outside of the optical disc 1; It is installed on a pickup guide shaft 4b which can be guided across the perimeter, and the pickup guide shaft 4b is fixed to the pickup base 3 by a mold or a press.
상기와 같이 설치된 픽업 가이드 샤프트(4b)는 상기 픽업본체를 상기 스핀들모터(2)에 장착된 상기 광디스크(1)상의 중심부와 외주변 사이에서 가이드하게 된다.The pickup guide shaft 4b installed as described above guides the pickup body between the center and the outer periphery of the optical disc 1 mounted on the spindle motor 2.
그러나, 상기와 같이 설치된 픽업 가이드 샤프트는 그 샤프트에 가이드되는 픽업본체에서 조사된 레이저광과 상기 스핀들모터에 장착된 상기 광디스크면과 수직을 이루도록 조정함에 있어 상기 픽업 가이드 샤프트의 3점을 기준하여 상기 광디스크를 장착하는 스핀들모터의 평행도를 조절하여야 가능하기 때문에 그 광디스크의 임의의 위치에서 상기 픽업본체에서 조사된 레이저광이 상기 광디스크면과 수직을 이루나 그 위치를 벗어나게 되면 조사된 상기 레이저광이 수직을 이루지 못하게 된다.However, the pickup guide shaft installed as described above is adjusted to be perpendicular to the surface of the optical disk mounted on the spindle motor and the laser beam irradiated from the pickup body guided to the shaft, based on the three points of the pickup guide shaft.
