Abstract

PURPOSE:To press a record disk onto a turntable securely by constituting a pusher, incorporated in the shaft of the turntable and pressing the record disk onto the turntable by magnetic suction force, so that while one magnetic pole is positioned over the shaft, the other magnetic pole will be around the shaft. CONSTITUTION:Pusher body 5 has permanent magnet 6 and pole plate 7 and, when incorporated in shaft 2, has magnetic pole A and other magnetic pole B arranged at the tip of and around shaft 2. On the surface of magnetic pole B, thin slider 8 made by copper plating or of a nonmagnetic material such as resin is provided. Under lower pole plate 7b, cushion material 14 is provided. Fitting pusher body 5 to the shaft makes cushion material 14 press record disk 3 by magnetic suction force. An adjustment is made by vertically moving magnetic pole piece 9 screwed in pole plate 7a so that the tip of shaft 2 will come into hermetic contact with concave part 10. Thus, record disk 3 can securely be pressed against turntable 1.
