ABSTRACT:
A disc chucking apparatus for use in an automatic disc changer for a disc player includes an arm base 28 which is vertically movable and reversible with respect to a chassis 1, and a disc base 34 fixedly mounted on the arm member. The disc base 34 has a central insert member 34a for being inserted in the central hole of a disc and a disc support surface 34b for abutting engagement with a peripheral edge of the central hole of the disc. A rod 35 extends axially slidably through the central insert member 34a, and a pantographic link mechanism 38 is operatively coupled between the disc base 34 and an end of the rod 35, and collapsible and extensible in response to sliding movement of the rod 35. When the arm base 28 is vertically moved in response to sliding movement of the rod 35, with the presser assembly 38 extended, the central insert member 34a and the presser assembly 38 are inserted into the central hole of the disc. Thereafter, when the presser assembly 38 is collapsed in response to sliding movement of the rod 35 caused by the cam 32, the disc is clamped between the presser assembly 38 and the disc support surface 34b.
