ABSTRACT:
A device for counteracting the inside force produced on the pickup arm of a record player includes a swing arm pivotally seated within an open end of a shaft mounted on the record player, the swing arm having weights thereon and being connected to the pickup arm to effect a following movement of the swing arm as the pickup arm moves toward the center of the turntable. The weights act to counterbalance the inside force produced by the pickup arm during movement thereof toward the turntable center so as to avoid undesirable shifting of the pickup arm when engaging a scratch or the like on the record. A cam surface at the interface of the shaft and the swing arm causes the swing arm to return to its initial rest position.
