ABSTRACT:
In a system for playing back prerecorded information from a disc record by a signal pickup mounted in a support housing, a signal pickup return mechanism is provided. The support housing is reciprocably mounted in the player cover by a suitable bearing. A drive mechanism drives the support housing radially inward in order to facilitate tracking of the disc record by the signal pickup. An extendible cord is provided with its ends attached to the base and the cover of the player. The cord extends when the cover is raised from the base. A leaf spring, with an open-ended slot, is attached to the support housing. The cord is threaded through the open-ended slot. A clamp secured to the cord is subject to engagement with the support housing, and is effective only in causing radially outward movement of the support housing. The clamp urges the support housing to return to a rest position when the cover is raised from the base.
