Abstract

PURPOSE: To attract a record disc onto a turntable through a simple operation by forming the upper side of a turntable sheet with a communication passage providing communication between a recess formed in the turntable and a suction opening.
CONSTITUTION: A turntable sheet 26 is molded of a material having elasticity and is placed on a turntable 20. The sheet 26 is formed step portion 26a, and the separated portions are arranged on the same radius while dividing the circumference into six idential portions. As a result, there are formed between the radially adjacent steps both a groove space 26c, which extends in the circumferential direction, and a groove space 26d which also extends in the circumferential direction. These groove spaces coact with the record disc 27 placed to form circumferential and radial air passages 28 and 29. The diametrical direction 21b is formed with a suction opening 21d in the space between the sheet 26 and a disc 27. Thus, if a pump 25 is operated during the play, the air above the upper side of the turntable is sucked so that the record disc is attracted onto the turntable.
