  • Patent number: 4482990
    Abstract: The sound-reproducing device for playing the record disc has a number of selection poles corresponding to the member of recorded grooves and a stylus force releasing wheel normally urged to a specific direction but which rotated by one of the selection poles to release stylus force on a pickup. The stylus force releasing wheel includes a locking arm confronting the back face of the selection pole in an advanced position for pushing the inclined face of the releasing wheel. Each of the selection poles has a jaw which catches the locking arm and prevents the selection pole when in an advanced position from retraction. A locking device locks the stylus force releasing wheel at the position to which the wheel has rotated. A record disc unit includes a turn table and a record face member disposed in a stacked but axially separable arrangement. A stopper pin is disposed on the record face member.
