Claim:
A disk holder springing-out prevention device provided for preventing a springing out of disk holders from a magazine in a disk change device of a magazine type that is constructed such that the device raises/lowers a disk feed section by horizontal movement of a sliding plate between a plurality of selection positions whereby one of a plurality of disk holders accommodated in a stacked fashion within a magazine is selected, the disk feed section is positioned at one of said plurality of raised/lowered positions respectively corresponding to said plurality of selected positions and said plurality of disk holders, a disk holder is extracted by the disk feed section and the disk that is held therein is fed to a playback position on a turntable, characterized in that said disk holder springing-out prevention device comprises: a holder extracting member that engages with a disk holder corresponding to one of said plurality of raised/lowered positions when the disk feed section is in one of the plurality of raised/lowered positions, a holder guide member for guiding the edge of a disk holder when the disk holder is extracted, and a stopper that is provided on said holder guide member and adapted in such a manner that, when said disk feed section is in an initial position, the stopper restricts at least one or more disk holders to accommodated positions within the magazine and when the disk feed section is in one of said plurality of raised/lowered positions, the stopper makes possible the extraction of at least one or more disk holders, including the disk holder corresponding to the one of the plurality of raised/lowered positions, wherein said stopper is adapted to be superimposed in a vertical direction with a disk holder engagement section of said holder extracting member when the holder extracting member is in the initial position in the disk feed direction; and said sliding plate is adapted in such a manner that the sliding plate performs ejection of the magazine in the vicinity of an initial position thereof.
