Abstract
The invention is a proposal of a pick-up drive apparatus for a disc player, which permits reducing the rotation resistance offered by a feed screw for driving a pick-up. A guide shaft and a feed screw are disposed side by side. an engagement part of a coupling member is held in radial and elastically forced contact with the feed screw. With rotation of the feed screw, the coupling member is thus advanced and retreated in the axial directions of the feed screw. A pick-up seat carrying a pick-up is caused to follow the coupling member for advancement and retreat along the guide shaft. The coupling member is mounted on the guide shaft for rocking movement and axial advancement and retreat. The coupling member has a pair of clamping pieces clamping the feed screw from the opposite sides in the direction of rocking movement. The engagement part is formed on one of the clamping members.
