  • Patent number: 4662667
    Abstract: Optical record disc handling apparatus for avoiding contamination of optical disc surfaces. A U-shaped handle supports on a first extending leg a centering post approximately midway between an inside edge of the supporting leg and the optical disc center. A remaining extending leg supports a pivotal gripping member which may be operated by the index finger. The pivotal gripping member is pivotal between a disc grasping position and disc releasing position. The centering post is advantageously spring loaded in the axial direction to permit a slight downward force to be applied to a centering hub in the disc storage package. The device is capable of being manufactured by standard injection molding techniques which are simple and economical.
