发明名称 Record player mat
摘要 A record turntable mat is provided with a groove made of record-like material. The groove is located so that if the record player is operated automatically when there is no record on the turntable the record stylus will engage the groove and thus not be damaged. Other portions on the upper surface of the mat are made of rubber-like material to support and drivingly engage a record when the turntable is rotated.
