ABSTRACT:
A disk record sound reproducing apparatus includes a turntable having a cylindrical rib formed on the lower surface thereof and protruding downwardly therefrom. A plurality of selection levers, equal in number to a number of modulated grooves of a disk record, are pivotably disposed below the turntable, the levers being arranged radially with respect to the center of the turntable. Each selection lever has a drawn-down arm and a holding arm which are respectively engageable with a part of the turntable and the lower edge of the rib. When one of the selection levers is turned, the turntable is lowered by the draw-down arm which presses down the part of the turntable, and at the same time, the holding arm rides over the lower edge of the rib and enters the inside of the rib. Thus, the turntable together with the record disk is maintained at its lowered position, and the application of stylus force to the disk record is released. With rotation of the turntable, when a cutout notch of the rib reaches the position of the holding arm, the holding arm is allowed to pass through the cutout notch, thereby to return the selection lever.
