ABSTRACT:
A support construction for an optical pick-up, such as used in a compact disc player, has a first leaf spring with an elongated opening defined between opposite sides in the longitudinal direction and an optical lens support centrally in the opening by a pair of support members extending from the opposite sides to allow the lens to be moved by a voice coil toward or away from the compact disc without sidewards deviation. The first leaf spring is supported on an intermediate base, and the intermediate base is supported by a pair of second leaf springs of similar construction, in order to allow the intermediate base to be finely adjusted by another coil in a plane parallel to the disc. The pair of second leaf springs are mounted to a slider which is driven radially of the compact disc.
