ABSTRACT:
A pickup arm pivotally coupled to a housing support at one end thereof, remote from a stylus carrying end, is also coupled to the housing near its other end by means of bimorph elements attached together at right angles. The bimorph elements are arranged such as to enable, upon proper actuation of the bimorphs, pickup arm movement in two orthogonal directions. With the housing mounted in a disc record player, over a turntable of the player, the bimorphs effect a lifting/lowering in addition to a lateral motion of the pickup arm relative to the turntable.
