Abstract

PURPOSE: To achieve high-prescision constant-speed rotation by making a rotary body freely separateable from the peripheral flank of a turntable, and enabling a bearing fitted with a turntable shaft loosely, to slide axially together with the turntable.
CONSTITUTION: A plunger 32 is fixed on a back plate 2a, and the iron core 32a of this plunger 32 is linked to a supporting plate 23 by a connecting arm 33. Further, the supporting plate 23 is activated as shown by an arrow (c) by a spring 34 fitted between the plate 23 and the back plate 2a. Therefore, rotations of a flywheel are transmitted to a driving shaft 24 by a rubber roller 25 and through the screwing operation between a screw part 24a and a nut 26, a driving lever 31 is turned to move a rotary bearing 28 to and from a sliding bearing 27 together with a turntable shaft 30, a turntable 29 and the flywheel 35, thus loading and unloading a record.
