Abstract

PURPOSE: To enhance tone quality and S/N etc. by attaching an oscillation preventing member to a guide rail of a linear motor, and absorbing an internal oscillation or the oscillation from the outside by this oscillation preventing member.
CONSTITUTION: A pickup arm 1 is supported freely rotatably by an arm holder 2 in a horizontal and vertical surface. The arm holder 2 is carried by a moving member 5 and this moving member 5 is so composed as to be movable along a pair of linear guide rails 6a, 6b attached horizontally. In a pair of guide rails 6a, 6b, an oscillation preventing member 12 made of rubber like viscoelastic member such as isobutylene-isoprene rubber is disposed in a moving direction of the pickup arm 1 and in a position where it is not allowed to contact with a roller 7. This oscillation preventing member 12 absorbs the oscillation or external oscillation produced during the moving of the moving member 5 and prevents the oscillation from being transmitted to the pickup arm 1. In such construction, the tone quality and S/N are enhanced.
