Sound record playing apparatus having shock responsive weight member to

Abstract

A turn table having a sound recording disk or record mounted thereon is normally urged upwardly by a spring disposed between a lower surface of the turn table and a chassis of a casing to apply a stylus force to a pickup. A weight member is rotatably and eccentrically supported on an inside mounting plate, and an operating claw having a slant surface formed on a lower surface is fixed to the weight member. When a shock is applied to the weight member externally, the weight member rotates by an inertia force in a plane perpendicular to a rotary shaft of the turn table. As a result, the operating claw on the weight member moves toward an upper end of the rotary shaft. The slant surface of the operating claw rides over the upper end of the rotary shaft to downwardly press the rotary shaft together with the turn table. Thus, the stylus force of the pickup is released. When the weight member returns to an original position, by a return spring, the operating claw retreats, and the turn table also returns to the upper position.
