Abstract:
A disk recording and/or reproducing apparatus comprising:a drive motor; a gear drive section including a center gear rotated by said drive motor and first and second planet gears meshed with said center gear and rotated by said center gear, said first and second planet gears revolving around said center gear; a rack portion selectively meshed with any one of said first planet gear and said second planet gear; a disk tray including a plurality of holding portions on which a plurality of disk-like recording mediums are held respectively, said disk tray being freely movable between an eject position at which at least one of said plurality of holding portions is projected to the outside of an apparatus body and a loading position at which at least one of said plurality of holding portions is loaded into said apparatus body; a recording and/or reproducing section for recording or reproducing at least one disk-like recording medium of said plurality of disk-like recording mediums held on said plurality of holding portions; and a preventing mechanism for preventing said first planet gear and said second planet gear from revolving when any one of said first planet gear and said second planet gear is meshed with said rack portion, wherein when said disk tray is moved to said eject position while said recording and/or reproducing section is being placed in a non-operation state, said preventing mechanism prevents said first planet gear and said second planet gear from revolving and said first planet gear is meshed with said rack portion to thereby allow said disk tray to move between said loading position and said eject position and when said disk tray is moved to said eject position while said recording and/or reproducing section is being placed in the state for recording or reproducing any disk-like recording medium of said plurality of disk-like recording mediums held on said plurality of holding portions, said preventing mechanism prevents said first planet gear and said second planet gear from revolving and said second planet gear is meshed with said rack portion to thereby allow said disk tray to move between said loading position and said eject position.
