    摘要： An adjustable stylus assembly for optimizing the output of a stylus while maintaining a predetermined contact pressure between the stylus and the groove of a video disc irrespective of the angle of attack of the stylus relative to the groove. A mounting head is provided having a curved bearing surface and a rotatably driver which frictionally captivates therebetween the driven portion of a stylus support arm. This driven portion has a curvature corresponding to that of the bearing surface so that, as the stylus is displaced along the bearing surface to adjust the stylus angle of attack, the stylus remains at the effective center of curvature of the bearing surface insuring that the contact pressure between the stylus and the groove remains substantially constant.

    摘要： In a video disc player, a support roller is mounted to one end of a pickup carriage by means of an eccentric stud. The height of the roller in respect of the carriage is adjusted by changing the angular position of the eccentric stud. A support bracket is disposed at the other end of the carriage, where a pair of adjustable members are provided for adjustment of the relative spatial position of the carriage and the support bracket.

    摘要： A device for the continuous adjustment of the stylus pressure in a record player. Vertical stylus pressure can be corrected by means of a load spring whose tensile force can be adjusted by moving the suspension end at the mounting side. The movable end of the load spring is attached to a carrier, which engages a spiral groove or ridge provided in the inner wall of an adjusting ring which is rotatable on the bearing block of the pick-up arm.
