摘要:
A signal pickup device for an apparatus for playing back an information storage medium such as a video disc comprises a cartridge casing mounted in a signal pickup device body, and a pickup cartridge housed in the cartridge casing and having a reproducing stylus for picking up signals from the video disc, a cantilever assembly composed of a cantilever supporting on one end thereof the reproducing stylus and a suspension member mounted on an opposite end of the cantilever, and a holder supporting the suspension member and attached to the cartridge casing for pivotable movement about the suspension member. The signal pickup device also has a coil through which a current passes for magnetically enabling the reproducing stylus to impose a stylus force on the video disc. The holder can be adjusted in angular position through the pivotable movement about the suspension member to adjust the stylus force. The holder is bonded to the cartridge casing after the holder has been positionally adjusted with respect to the cartridge casing.
