Abstract
A device for centering a disc to be read or recorded while rotating includes a turntable and a plurality of centering parts resiliently connected thereto and extending above the supporting surface thereof concentrically about the axis of rotation. Each centering part has a pair of connection strips connected thereto remote from its free end and extending toward the axis of rotation, each connection strip also extending toward and being connected to an adjacent connecting strip extending from another connecting part. Deflecting a free end of any centering part toward the axis of rotation causes other such parts to be likewise deflected, thereby assuring concentricity of the disc with the axis.
Claims12
A device for centering a disc to be read or recorded while rotating, said disc having a central disc hole, said device comprising:
- a turntable having an axis of rotation and a supporting surface for a disk,
- a plurality of centering parts resiliently connected to said turntable and situated concentrically about said axis of rotation, said centering parts each having a pivot which extends at least substantially tangentially with respect to a circle situated concentrically about the axis of rotation, said centering parts having free ends which can be pivoted resiliently about said pivots and toward the axis of rotation, said centering parts extending above the supporting surface and being situated at least partly in the central disk hole when the disk is in the operating position,
- a pair of connection strips connected to each centering part remote from its free end and extending toward the axis of rotation, each connection strip extending also toward an adjacent connection strip extending from another centering part, each connection strip having an end remote from the pivot and the centering part to which it is connected, each said end of said strip being connected to the end of said adjacent strip.
