PROBLEM TO BE SOLVED: To improve the accuracy of disk reproduction by bonding a driving motor shaft and a turntable assembly under the state, in which the shaft section of the turntable assembly and the shaft section of a driving motor are gripped respectively, when the diving motor shaft is pushed into the cylinder type core section of a support shaft member for the turntable assembly. SOLUTION: A turntable fixing member 170 is installed onto a support base 110 while being oppositely faced to a motor fixing section 120. A turntable assembly 200 can be mounted detachably on the member 170, and the member 170 is arranged accurately so that the central axis of the member 170 is placed on the extension of a driving motor shaft 211. Consequently, when the assembly 200 is set up, the shaft of the assembly 200 can be made the same as the shaft 211 of a motor 210 accurately. Accordingly, the assembly 200 and the shaft 211 are bonded with high accuracy, and the accuracy of reproduction is improved. |
