SO1027 S78P52 A DEVICE FOR HOLDING A ROTATABLE RECORD DISC ABSTRACT OF THE DISCLOSURE A device for holding a rotatable record disc includes a support base rotatable about a central axis and having a supporting surface normal to the axis for sup- porting one side of a record disc and a projecting boss engaging the central hole of the disc for aligning the disc with respect to the axis, and a clamp assembly having a clamp housing, adapted to be disposed at the other side of the record disc, and provided with locking elements for locking the clamp housing with respect to the base against movement away from the latter. The locking elements are radially, slidably mounted in the clamp housing and have locking claws extending from their inner ends for engaging respective locking recesses in the rotatable base. The locking elements have portions exposed at diametrically opposed sides of the clamp housing for allowing manual urging thereof to provide simultaneous release of the locking claws and removal of the clamp assembly from the support base. The clamp assembly further has a clamp base extending from the clamp housing for engaging against the other side of the record disc and being movable relative to the clamp housing in the direction of the axis, and -1- springs urging the clamp base relative to the clamp housing in the direction of the axis toward the other side of the record disc for clamping the latter between the clamp base and the supporting surface.
