Abstract:
1. A disk loading mechanism comprising: a feeding mechanism capable of loading and unloading disk media of different diameters into and from a disk device; a turntable that holds and rotates said disk medium loaded by said feeding mechanism; a cam slider for moving said turntable between a position where said turntable is able to hold said disk medium and a position apart from said disk medium; a driving mechanism for driving said cam slider; a disk stopper provided to be movable in a loading-unloading direction of said disk medium, said disk stopper regulating a loading position of said disk medium by abutting against said disk medium; a stopper regulating member that regulates a movable range of said disk stopper, and a link member movable in association with said stopper regulating member and having first and second engaging portions, wherein said link member has a disk abutting portion pushed by a disk medium of a predetermined diameter, and is shiftable in a direction different from said loading-unloading direction when said disk abutting portion is pushed by said disk medium; wherein said cam slider has a first engaging portion that engages said first engaging portion of said link member in a state where said disk abutting portion is not pushed, and a second engaging portion that engages said second engaging portion of said link member in a state where said disk abutting portion is pushed; wherein said first engaging portion of said cam slider and said first engaging portion of said link member are configured to engage each other thereby regulating said link member at a first position in said loading-unloading direction during the movement of said cam slider, so as to cause said stopper regulating member to regulate said disk stopper at a predetermined position in said loading-unloading direction, and wherein said second engaging portion of said cam slider and said second engaging portion of said link member are configured to engage each other thereby regulating said link member at a second position in said loading-unloading direction during the movement of said cam slider, so as to cause said stopper regulating member to regulate said disk stopper at a position shifted in a loading direction from said predetermined position.
