Problems solved by technology

[0012] However, if image 3 As shown, the rubber pad 13 formed on the upper side of the turntable 10 in the disc clamping device installed in the original disc player is a ring structure, which is unstable when different discs are placed, and in order to paste the ring rubber pad 13 On the turntable 10, double-sided tape is used, so there is a problem that it is also very disadvantageous in terms of cost reduction and the like.
