Abstract
A disc-record player includes a pressure apparatus for pressing a disc onto a turntable. A mandril which is coaxial with the turntable engages the edge of a center hole in the disc. The pressure apparatus comprises rollers which can deflect elastically in a radial direction relative to the axis of rotation of the turntable and which are carried by a pressure member. The pressure member is axially movable relative to the mandril and acts on the disc at a radial distance from the center hole. The mandril comprises a conical guide wall whose diameter decreases towards the turntable and which cooperates with the rollers when downward pressing action occurs.
