Title:
FREELY FLOATING MOUNT FOR SUPPORTING HOLOGRAPHIC DISC FOR SCANNER
Document Type and Number:
Japanese Patent JPS60194420
Kind Code:
A
Abstract:
A spinning disc apparatus, for example for the holographic disc (10) of a scanner, which enables centrifugal force developed by rotation of the disc to bring the disc into perpendicular relationship with the axis of the disc motor shaft (25) and prevent disc wobble, comprising, a first self aligning coupling (29) composed of a pin (31) and socket (34) for supporting the disc on the end of the motor shaft, the shaft (25) and the disc (10) having coaxial bores (27, 57) therethrough; a tensioning cable assembly (30) extending through the motor shaft and disc bores, one cable segment (40) of the cable assembly being attached to a retaining ball (38) receivable in a socket (39) in the disc, the retaining ball and socket forming a second self aligning coupling (37); a second cable segment (41) at the opposite end of the cable assembly having a retaining ball (36) attached thereto receivable in a socket (33) in the motor shaft end and forming a third self aligning coupling (35); an extension spring (42) interconnecting the first and second cable segments (40, 41) to form the cable assembly whereby the motor shaft and disc are biased through the second and third self aligning couplings into engagement through the first self aligning coupling to drivingly mount the disc on the motor shaft.
