Abstract

Abstract In a video disc player, a support roller is mounted to one end of a pickup carriage by means of an eccentric stud. The height of the roller in respect of the carriage is adjusted by changing the angular position of the eccentric stud. A support bracket is disposed at the other end of the carriage, where a pair of adjustable members are provided for adjustment of the relative spatial position of the carriage and the support bracket.
