    摘要： A capacitance detection type stylus is attached to the free end of a cantilever which is supported on a vertically movable resilient pivot. A permanent magnet is fixed to the movable pivot. A servo-control coil is provided adjacent the permanent magnet to move it in response to angular displacement of the cantilever from a predetermined position. The pivot is moved in the direction of fluctuation of a disc record to maintain the stylus in a proper orientation with respect to the record surface.

    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： A reproducing stylus traces a track of a recording medium, in which track an information signal is recorded as variations of geometrical shape, and reproduces as variations in capacitance the information signal thus recorded. The reproducing stylus comprises a reproducing stylus main structure having a tip part with a flat sliding contact face for slidingly contacting a plurality of track of the recording medium at a time, and an electrode secured to the reproducing stylus main structre at the tip part thereof and adapted to trace one track and reproduce the information signal as the variations in capacitance in accordance with the variations in geometrical shape. The electrode has over a specific distance over the tip part of the stylus main structure from the extreme tip thereof, a constant width in the width direction of the track which is less than the width of the track. The extreme tip of the electrode has a flat or linear tip end contacting the track.
