Abstract
A disc record apparatus having a fixed housing including an entrance slot for a disc record and a surface to slidably receive a disc record inserted edge first in its own plane through said slot to a playing position has a drive spindle for the disc record mounted in a spindle or motor housing for translation axially of the spindle and perpendicularly relative to the plane of the disc record. The spindle is movable in tranlation from an insertion position displaced from the plane of the record to an operative position in engagement centrally with a disc record in playing position for rotating the disc record. A motor driven cam member translates the spindle housing. A movable gate is provided for the entrance slot and the motor driven cam member is connected for opening and closing the gate so that a disc record may be inserted or ejected coordinated with translation movement of the spindle. An ejection mechanism driven from the same motor driven cam member is provided for automatically ejecting the disc record.
