  • Patent number: 4498160
    Abstract: A simplified record player having a fixed record member and a rotatable turn table carrying a sound reproducing stylus which rotates together with the turn table. Until the record is positioned on the record holding portion of the player, the reproducing stylus is disposed in a recessed portion or an opening so as to be shielded from the outside. When the record is positioned and fixed to the record holding portion, a projecting rod attached to the center of the record pushes a pusher placed about the center pin of the player such that the pusher advances along the center pin. By a wedge action given by an inclined face of the head of the pusher, a tone arm carrying the reproduction stylus is pushed outward so that the reproduction stylus can be positioned to confront the recorded face of the record. By virtue of this construction, the design defect of injuries to an operator's body by an exposed stylus can be entirely prevented.
