ABSTRACT:
In a disc-record player comprising a turntable which is mounted for rotation in a frame there is provided a pressure lever which is pivotally connected to the frame by a spindle. The pressure lever comprises an arm portion and a pressure portion, the arm portion being connected to the frame by said spindle and the pressure portion being connected to the arm portion by another spindle which extends parallel to the first-mentioned spindle. The pressure portion carries a pressure member which can be moved towards the turntable from an inoperative position into a press-on position by pivoting the arm portion. In the press-on position the pressure portion exerts pressure on the pressure member via a ball, the ball and the pressure member being at least substantially coaxial with the turntable in the press-on position. By pivoting the pressure portion relative to the arm portion the pressure member extends substantially parallel to the upper surface of the turntable both in the inoperative position and in the press-on position.
