ABSTRACT:
In a signal pick-up apparatus for reproducing a recording disc, a pick-up cartridge casing is detachably loaded at a predetermined position on a pick-up apparatus structure. An arm is rotatably supported at one end thereof, within the casing. At its other end, the pick-up arm has a reproducing stylus which contacts the recording disc, an elastic member for supporting the pick-up arm with respect to said arm support member, and a member for urging the arm support member in a direction which accommodates the pick-up arm within said casing. The other end of the arm support member is depressed, within a direction for causing the reproducing stylus to contact the recording disc and further causing the elastic member to deform after a contact between of the reproducing stylus and the recording disc.
