摘要： A video disc signal pickup cartridge is described wherein the stylus arm is coupled to the cartridge body by a highly compliant relatively long, flat member suspended vertically from the top wall of the cartridge. The stylus arm is coupled to the member by passing one end of the arm through a tight fitting hole in the distal end of the member. The member is necked down near the hole to increase torsional compliance with respect to axial rotation of the stylus arm. The proximate end of the member has an expanded compliant region which is compressed for passage through a mounting hole in the cartridge body and allowed to re-expand to compressively retain the member in the hole.

摘要： A video disc player includes a carriage supporting signal processing circuitry having an electrical input terminal. A pickup cartridge which is removably mounted in said carriage contains a stylus and an electrical connection between an electrode on said stylus and a terminal on the cartridge. The cartridge terminal engages the input terminal of the signal processing circuitry under operating conditions. During installation of the cartridge in the carriage, cartridge projections cooperate with cam surfaces provided in the carriage to hold the terminal on the cartridge in spaced relation to the input terminal until the two terminals are aligned, to prevent a shearing motion therebetween.

摘要： A pickup cartridge encloses a stylus arm carrying a stylus at one end thereof. The other end of the stylus arm is secured to a connector plate via a compliant member. A spring releasably clamps the stylus arm in a retracted position. A pair of elastic straps extend between a pair of spaced end ribs. The rear end of the cartridge has a pair of hooks for releasably retaining the pair of spaced end ribs. The rear surfaces of the elastic straps are at a certain angle with respect to the front surfaces thereof. The connector plate is secured to the slanted rear surfaces of the elastic straps to establish an angular orientation of the connector plate relative to the cartridge so that, when the stylus arm is held in the retracted position in the cartridge, the compliant member is unstressed. The connector plate is adapted to be rotated upon reception of the cartridge in a player to permit the stylus arm to protrude outside the confines of the cartridge without stressing the compliant member. The clamping spring is locatable in one of three positions relative to the cartridge. In the top position, the clamping spring retains the stylus arm in the retracted position against a stop in the cartridge. The middle position of the clamping spring permits the stylus arm to protrude outside the confines of the cartridge. The bottom position is for manufacturing pusposes. Means are provided for accurately positioning the cartridge in a compartment provided in the player.

摘要： A stylus for stereo pickups tracking acoustic events mechanically recorded in grooves of a plate shaped record carrier comprises a soft iron tube which is adapted to embody a transducer and which has an open end into which a needle support tube is engaged and secured such as by adhesive connection. The needle is carried by the support with its axis substantially perpendicular to the axis of the support tube at the outward projecting end of the tube. The soft iron tube and the support tube are engaged in an opening of a support plate and embraced by a first elastic element engaged in the opening and elastically engaged with the soft iron tube. The construction includes a second elastic element engaged around a portion of the soft iron tube and the support tube at a location adjacent the open end of the soft iron tube and forms a damping body of a material of high internal friction.

摘要： In a combined stylus and generator system, the combination with a stylus adapted to operate with a record groove and a generator moving in response to the movement of said stylus means for suspending the stylus and generator system for universal movement. The means for suspending the system includes a pivot member connected to a rigid support and seated in an elastomeric socket member proximate the end of the stylus lever. The pivot member is preloaded in the elastomeric socket member by a second elastomeric member coupled between the rear of the stylus lever and the support. Lateral motion of the generator system is damped by non-linear compressive forces in the preloaded elastomeric socket member, while forces on the stylus causing the generator system to swing about the pivot member are damped by opposing shear compliance forces in the elastomeric socket member which act to return the stylus to its neutral position.
