Abstract

PURPOSE:To commonly use chuck part for disks different in type by providing a turning arm to be fixed to a turning axis and plural chuck members to be provided with standing in the tip side of the arm and to lock the inner circumference edge of the central part of the disk. CONSTITUTION:The >=2 chuck members are engaged to an inner circumference edge 18b of a disk 18 and the chuck member is constituted of a turning arm 1 and the locking part of the inner circumference edge to be provided with standing on the tip part of the arm. Since the respective turning arms 1 are turned by a belt, a roller 2 or a gear, the disk of a different size can be chucked by the locking part. Moreover, for the belt, the roller 2 or the gear, since revolving force is transmitted with engaging to a revolving axis in the outer circumference side or inner circumference side of a turning axis 3 of the turning arm 1, a turning mechanism is not needed to be larger. Thus, the size of the turning mechanism is obtained for a chuck case not to contact to the circumferential wall surface of an aperture part in a cassette side and it is not necessary for a using to change the constructure of the cassette. Further, to the disk of a different outer diameter, the same disk chuck part can be used by simply enlarging a turning angle.
