Abstract

An actuating shaft 12 of a friction-based actuating wheel 11 is supported at both ends by bearings 13 arranged in the horizontal direction on the lower part of the protective casing 1, said bearings being movable in the axial direction (in the vertical direction) of the central shaft 4 which supports the turntable unit 5. When the friction-based actuating wheel 11 descends towards the ground or the bottom and runs over the ground, the peripheral portion of the friction-based actuating wheel is taken to a position of contact with the lower surface of the turntable 3, thereby causing rotation of a disc recorded via the turntable unit 5. The turntable unit 5 includes a buffer spring 9 provided between the recorded disc and the turntable in order to maintain an appropriate needle force even when the turntable unit is impelled excessively upwards owing to the ascending movement of the friction-based actuating wheel.
