Beschreibung
Zusammenfassung:	In a record player of the direct drive system wherein a turntable and a motor for driving the turntable are directly coupled; a record player characterized in that a cancellation mechanism is disposed coaxially with the driving motor, said cancellation mechanism performing a reciprocating rotational motion to generate to a torque equal in magnitude and reverse in direction with respect to a torque fluctuation developed by rotation of said driving motor, thereby to cancel counteractive rotational vibrations exerted on a cabinet of said record player by said driving motor.
