Abstract

본 발명은 여러개의 레이저 디스크가 탑재된 상태에서 특정 레이저 디스크를 선택적으로 플레이시키는 멀티레이저 디스크 선택적으로 플레이시키는 멀티레이저 플레이어(MLDP; Multi Laser Disk Player)에 있어서, 픽업(pick up)의 위치를 정확하게 세팅하게 위한 오프-엑시스(OFF-AXIS) 조정장치에 관한 것이다. 종래에는 오프-엑시스 조정시마다 그레이팅(grating)이 많이 틀려지게 됨으로써 다시 그래이팅을 조정하기 위하여 오프-액시스 조정 작업을 여러번에 걸펴 실시하여야 하는 번거로움이 있었으며, 또한 픽업의 수납동작이 원활하기 못한 문제점이 있었다. 본 고 발명은 조정 나사(35)의 회전에 의하여 조정용 브래키드(34)를 직선이동되도록 하고, 상기 조정용 브래키트(34)의 이동에 의하여 가이드 샤프트(32)가 고정된 샤프트 고정 브래키드(36)를 직선이동을 가능하게 함으로써 오프-액시스의 조정 작업을 보다 용이하게 하고, 픽업의 수납 동작을 보다 원활하게 하도록 한 것이다.The present invention relates to a multi-laser player (MLDP) for selectively playing a specific laser disk in a state where a plurality of laser disks are mounted, so that the position of the pickup (pick up) is precisely determined. An OFF-AXIS control device for setting. In the related art, since the grating is very different every time the off-axis adjustment, there is a problem that the off-axis adjustment operation must be carried out several times in order to adjust the grating again, and the pick-up operation of the pickup is not smooth. There was this. The present invention allows the adjustment bracket 34 to be linearly moved by the rotation of the adjustment screw 35, and the shaft fixing bracket 36 to which the guide shaft 32 is fixed by the movement of the adjustment bracket 34 is fixed. By making the linear movement possible, the adjustment operation of the off-axis is made easier and the storage operation of the pickup is made more smooth.
