ABSTRACT:
A pick-up mechanism for a disk-type record medium reproduction apparatus is disclosed. This mechanism is suitable for use in a compact disk player and employs a plate spring to connect a nut mounted on a pick-up moving screw with the pick-up unit. Pressure contacts mounted on the outer surface of the nut and on the front end of the plate spring, steady the nut and eliminate gaps between the nut and the pick-up screw. By eliminating these gaps, information can be read from the disk with increased precision.
