  • Patent number: 4728157
    Abstract: A disc holder comprises a rigid box which is solid on five of its six sides. The sixth side is hinged on one end thereof to a first side, either the top or the bottom, of the compact disc holder. A spindle is mounted within the rigid box and along a track therein. The spindle is configured so as to conform to a hole at the center of the disc to be held. Upon actuation of a linear actuator, a first gear, coupled to the spindle, is rotated, thereby causing the spindle to proceed in a first direction along the track, past the sixth side of the rigid box, and to the exterior thereof. When the spindle reaches a predetermined point relative to the exterior of the rigid box, it retracts slightly, releasing the disc held thereby, so that the disc may be removed and used, as desired.
