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： The invention provides a method and apparatus for rapid and accurate stylus overhang positioning and tangential alignment with respect to a turntable. Accordingly a stylus locater plate having an aperture and a stylus positioning mark spaced therefrom is mounted on the spindle of a turntable. A pivot arm is connected to the locater plate on the other side of said spindle from the stylus positioning mark. The pivot arm and thus the locater plate, are then rotated around the spindle until such arm crosses over the pivot axis of the stylus arm of the turntable, to locate the mark in the turntable. The stylus arm is then pivoted toward the mark and the stylus cartridge is adjusted in the stylus arm to position the stylus in registration with such mark.The locater plate is further provided with lines near such mark to guide the angular positioning of the stylus cartridge into a tangential alignment with the record grooves at such mark.

摘要： In a record player an overload coupling is arranged between a command disk and a pick-up arm controlled by the disk. The coupling comprises two coupling members which are pivotable relative to each other out of a neutral position about an axis, which members each comprise a guide which is concentrically curved around the axis. Viewed parallel to the axis, the guides coincide in the neutral position. A continuous helical spring, whose ends bear against end portions of the guides in the neutral position, is slid over the guides.

摘要： A stylus guard assembly for use with a phonograph pick-up cartridge, which assembly includes a cam member, a manually operated lever with a pivot operating arm and walls providing detent surfaces. The pivot operating arm is disposed at an angle to a lever which engages a curved cam slot on a stylus guard. When the lever is manually displaced through its designated travel, the movement at the end of the arm, through the action of the cam mechanism, causes the guard to rotate on its pivot from one position to another. In one position, the guard is retracted to expose the stylus. In both positions, the guard is held in place by the detent mechanism. The manually operated lever produces a visual indication of the stylus guard position, which shows whether the stylus guard is in the position to allow the stylus tip to engage with the recording or is in the position to protect the stylus when not in use.
摘要翻译：一种用于留声机拾取盒的触控器组件，该组件包括凸轮构件，具有枢转操作臂的手动操作杆和提供制动表面的壁。枢轴操作臂设置成与操作杆成一定角度，该杆与触针保护罩上的弯曲凸轮槽接合。当手柄通过其指定的行程手动移位时，通过凸轮机构的作用在臂的端部处的运动导致防护件在其枢轴上从一个位置旋转到另一个位置。在一个位置，护罩被缩回以露出触针。在这两个位置，守卫通过制动机构保持在适当位置。手动操作的杆产生触控笔保护位置的视觉指示，其显示触针防护件是否处于允许触针尖端与记录接合的位置，或者在不使用时保护触针的位置。

摘要： A gramophone pick-up arm has a balance weight arrangement which comprises a selectable number of lead laminations contained in a molded plastic box constituting a main balance weight casing which is adjustable in two directions, one direction being aligned with the axis of the arm at its pivotal and rotational bearings and the second direction being aligned with the pivotal axis of the arm. Light weight plastic spacers may be included in the box to prevent the lead laminations from moving about therewithin. The main balance weight casing carries a pair of flanking rider weights arranged laterally with respect to the length of the arm, one of the rider weights being provided with a micrometer screw adjustment whereby its position relative to the main balance weight casing can be precisely set for fine control, and the other rider weight providing coarse control and being indexable between forward and rearward limiting positions. Apart from the weights per se, all components of the balance weight arrangement are formed of precision molded glass or carbon fiber loaded plastic, as also is a bearing carrier into which the arm proper plugs, and from which the balance weight arrangement is adjustably carried, and integral with which are knife-edge bearing portions. The arm proper is a titanium tube processed in an atmosphere of nitrogen so as to develop a hard titanium nitride outer layer.
摘要翻译：留声机拾音臂具有平衡配重装置，其包括可选择数量的引线叠片，其包含在构成主平衡重壳体的模制塑料盒中，所述主平衡重壳体可在两个方向上调节，一个方向与臂的轴线对准枢转和旋转轴承，并且第二方向与臂的枢转轴线对准。盒子中可能包含轻质塑料垫片，以防止铅片在其间移动。主平衡重壳体承载相对于臂的长度横向设置的一对侧翼骑手重量，其中一个骑手重量具有千分尺螺丝调节，由此其相对于主平衡重壳体的位置可精确地设定为精细控制，另一个骑手重量提供粗略控制，并且可以在前后限制位置之间进行转位。除了重量本身之外，平衡配重装置的所有部件均由精密模制玻璃或碳纤维装载的塑料形成，并且臂本身也可插入其中并由平衡重装置可调节承载的承载载体，并且与刀沿轴承部分成一体。臂本体是在氮气气氛中加工的钛管，以形成硬的氮化钛外层。

摘要： A reproducing apparatus for a disk-shaped recording medium, wherein a pickup detects signals from a rotating disk-shaped recording medium in contact with the latter. The reproducing apparatus is so constructed that vertical and horizontal movements of the pickup can be selectively made by actuating only one control knob, and that the horizontal movement of the pickup is prevented when the latter is in contact with the disk-shaped recording medium, even if the control knob is erroneously or accidentally actuated.

摘要： A tone arm adapted to be disposed between a head shell and a holder for the tone arm, the tone arm comprising at least one hollow member contacting the head shell or the tone arm support and having an orientation axis extending through the hollow portion of the hollow member where the angle .theta. between the orientation axis and an arm shaft axis extending between the head shell and the tone arm holder is greater than 0.degree. whereby a mechanical vibration introduced into the tone arm from a vibration source comprising either the head shell or the tone arm holder is divided between two paths both of which start at the contact point between the hollow member and the vibration source and then pass around the respective sides of the hollow member to a cancellation point where the vibrations in the two paths substantially cancel one another due to difference in their direction of travel.
