Abstract
A disk recording and/or reproducing apparatus recording and/or reproducing information on and/or from anyone of a plurality of disk-like recording mediums. Freedom in design is improved by effectively utilizing spaces in which respective portions and mechanisms of the apparatus are disposed. In the apparatus, a first planet gear and second planet gear meshed with a racked portion are switched, whereby the disk tray is moveable between a loading position at which the disk tray is loaded into the apparatus and an eject position at which the disk tray is ejected to a location outside the apparatus body.
Claims25
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.

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 being 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 being ascended and descended between an ascending position at which any one disk-like recording medium of said plurality of disk-like recording mediums held on said plurality of holding portions is recorded or reproduced and a descending position lower than said disk tray;
- and
- a preventing mechanism for preventing a first planet gear and a 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 said preventing mechanism prevents said first planet gear and said second planet gear from revolving when said disk tray is moved to said eject position while said recording and/or reproducing section is being located at said descending position and when said disk tray is moved, 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 located at said ascending position, and wherein 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 be moved between said loading position and said eject position.
4 more elements
A disk recording and/or reproducing apparatus comprising:
- 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 moved between an eject position at which at least one holding portion of a plurality of holding portions is ejected to the outside of an apparatus body and a loading position at which at least one holding portion of a plurality of holding portions is loaded into said apparatus body;
- a moving mechanism for moving said disk tray between said eject position and said loading position;
- a recording and/or reproducing section ascended and descended between an ascending position at which any one disk-like recording medium of said plurality of disk-like recording mediums held on said plurality of holding portions is recorded or reproduced and a descending position lower than said disk tray;
- an ascending and descending drive section for ascending and descending said recording and/or reproducing section between said ascending position and said descending position, wherein said ascending and descending drive section includes a cam gear rotated by said moving mechanism and a cam assembly rotated by said cam gear and said recording and/or reproducing section is ascended and descended between said ascending position and said descending position as said cam assembly is rotated;
- and
- a holding mechanism for holding said recording and/or reproducing section at said ascending position when said recording and/or reproducing section is located at said ascending position wherein said holding mechanism comprises a swing lever swung by said cam assembly and a supporting groove formed on said disk tray and which is engaged with said swing lever.
