Optical pick-up feeding device having a regulating member to adjust an orientation of a lead screw thereof

摘要

An optical disc is read by being mounted on a turntable which rotates about a vertical axis, and moving an optical pick-up radially relative to the vertical axis. The optical pick-up is slidably mounted on a horizontal guide shaft and is threadedly mounted on a lead screw which is rotatable about a horizontal axis extending parallel to the guide shaft. A first end of the lead screw is connected to a motor, and the second end is mounted in a holder which is displaceable relative to the base to enable the second end to be displaced horizontally, in order to correct the horizontal orientation of the lead screw.
