摘要： A disk player compatible with two types of large and small diameter disks is provided. A startup arm 20 is transversely moved by a selection arm 50 turned by abutment of a side edge of a large diameter disk 14b. Then, the startup arm 20 turning together with a shift bar 17 moved to be pushed at the front edge of the disk 14b is longitudinally moved. A cam follower pin 25 is engagingly locked with a pocket 53c by a spring 24, and the startup arm 20 is constrained in cooperation with a swivel shaft 22, whereby the shift bar 17 is restricted, and the center of the large diameter disk is positioned. The small diameter disk 14a restricts the shift bar 17 by the startup arm 20 by which the cam follower pin 25 is engagingly locked with the pocket 43c by the spring 24 irrespective of the selection arm 50. The center of the small diameter disk is positioned at the same central position as that of the large diameter disk.

摘要： A disk loading mechanism has a turntable. A turntable 36 itself is fixed in external dimensions of a brushless spindle motor, and a chucking face relevant to a disk 11 is precisely placed on a turntable base 46 with a predetermined height. On the turntable base 46, columns 47 are embedded in three directions on a circumference which surrounds the outer periphery of the turntable 36. A column tip end stepped portion 47b and a disk placement face 36a of the turntable 36 are precisely constructed in predetermined dimensions. When the column tip end stepped portion 47b abuts against a bottom face (a reference face L) of a drive board 15, a relative position between the disk placement face 36a of the turntable 36 and a pickup constructed while the bottom face of the drive board 15 is defined as a reference is precisely determined.
