Provided in the vicinity of both sides of a disk loading slot, are rods which rotate when contacted by a disk that is loaded, and disk check levers which are in contact with the rods and rotate by a principle of a lever. With such a disk loading apparatus, when loading a disk into a reproduction apparatus, incorrect loading of a disk due to a difference in disk sizes is prevented.

Disk loading apparatus with independent detection devices

A disk retaining mechanism that realizes a reduction of its thickness while maintaining a clamping force and a centering accuracy of the clamper, with a structure, in which: a guide ( ) is disposed in a manner to closely confront a clamper retaining member ( ); a clamper unit retaining portion of the clamper retaining member ( ) has such a shape that a part of which an entire circumference is cut out; a clamper unit for depressing a disk ( ) is provided with a disk holder ( ) having an engagement projection (M); and an annular engagement groove (F) formed in a turntable ( ) for loading the disk ( ) is arranged below an upper end of a main shaft ( ) that transfers rotation of a motor unit ( ).
