TITLE OF THE INVENTION: Pickup Arm Lifting Device ABSTRACT OF THE DISCLOSURE: A pickup arm lifting device in which a follower magnet is attached to the lower end of a slide shaft disposed for vertical movement for lifting or lowering a pickup arm, and a lifting magnet and a lowering magnet are mounted on an operating plate and are so magnetically oriented that the lifting magnet repels the follower while the lowering magnet attracts the follower magnet, whereby when the operating plate is so displaced as to bring the lifting or lowering magnet in line with the follower magnet, the follower magnet is repelled away from or attracted toward said lifting or lowering magnet and consequently the slide shaft is lifted or lowered to lift or lower the pickup arm. - 1 -
