Abstract

A disk holder springing-out prevention device is constituted by utilizing an existing loading block LB. A disk holder 3 is restricted to an accommodated position within a magazine M by means of a stopper 1a provided on a holder guide rail 1. In general, the initial position of the loading block LB is adapted to be a raised/lowered position corresponding to the uppermost disk holder 3 and the stopper 1a is adapted to be superimposed in the vertical direction with an engagement projection 2a of a holder extracting member 2 when the holder extracting member 2 is in the initial position in the feed direction. In this way, positional restriction of the uppermost disk holder 3 is effected by the holder extracting member 2 whereas the stopper 1a performs positional restriction of the remaining disk holders 3. As a result, springing out of the disk holders 3 from the magazine M can be reliably prevented.
