    摘要： A signal pickup cartridge is mounted in a signal pickup device having pivot bearings and an actuator driven by the pivot bearings in response to a control signal. The pickup cartridge comprising a cantilever provided at a distal free end thereof with a reproducing stylus for tracing along a track which is formed on a rotary recording medium lying in a horizontal plane and has an information signal recorded therealong and thereby reproducing the information signal. The cantilever is supported at a proximal base end thereof by the pivot bearings in a swingable manner and, moreover, in a manner making possible displacement thereof in the longitudinal direction thereof. The pickup cartridge further comprises pressure contact mechanism for holding the cantilever when the pickup cartridge is in the state thereof prior to the mounting thereof in the signal pickup device and for causing the proximal base end of the cantilever to be pressed into contact with the pivot bearing when the pickup cartridge is in the mounted state in the pickup device, and elastic members capable of absorbing vibration provided at one part of the pressure contact mechanism and holding the cantilever at a part thereof near the proximal base end.

    摘要： In a video disc playback system including a motorboard, a turntable, an information disc, a stylus, a stylus arm, and a stylus arm carrying structure, a universal stylus arm pivot coupling is provided for coupling the stylus arm to the carrying structure. The coupling comprises a generally horseshoe-shaped stylus arm holder affixed to the stylus arm. A plug, having a tapered end with a substantially circular cross-section, is fastened to the first leg of the arm holder. A support member, also generally horseshoe-shaped, is attached to the carrying structure. An opening, having dimensions permitting only a partial entry of and presenting complementary bearing surfaces for smooth engagement with the plug, is disposed in the first leg of the support member. A spring is connected between the second legs of, respectively, the arm holder and the support member. The spring member persistently urges the plug into the opening and provides tracking pressure between the stylus and the disc during playback.
