Abstract
A mechanism for supporting a pickup arm in a linear tracking arm type disc record player comprising an upper guide rail having a groove, a lower guide rail extending parallel to the upper guide rail, and a pickup-arm supporting movable frame having first rollers engaging in the groove of the upper guide rail for suspension of the movable frame therefrom and having second rollers contacting the lower guide rail to allow the movable supporting frame to make smooth linear travel on this lower guide rail without unwanted pivotal movement. This arrangement insures smooth linear tracking of the pickup arm with no rattling-type travel and eliminates the need for highly trained skill in assembling the whole mechanism.
