Abstract
A disk exchanger apparatus including a disk gripper and a disk exchange mechanism capable of horizontally holding a disk cartridge and selectively introducing and removing the disk cartridge through access openings at both sides of the gripper from disk storage devices horizontally storing a plurality of disk cartridges on either side of the disk gripper, and a movable storage unit capable of storing a plurality of disk cartridges to be loaded in one of the disk storage devices through an access door whereby the disk cartridges may be transported and stored in a horizontal position and selectively transported between the storage unit and the disk storage devices.
Claims9
A disk storage apparatus comprising:
- a disk gripper including a holder for horizontally holding a disk cartridge and disk exchange means for selectively introducing onto and removing a disk cartridge from said holder;
- a disk transport device including means for vertically moving said disk gripper to stop at a given position;
- at least one disk storage device arranged on at least one side of a transport path of said disk gripper and adapted for horizontally storing a plurality of disk cartridges;
- a moving storage unit loaded in a lower part of at least one said disk storage device and including a storage pack for horizontally storing a predetermined number of disk cartridges;
- a loading door for said moving storage unit formed in an outer wall of a loading portion of said storage apparatus;
- locking means for inhibiting opening of said loading door during the transfer of a disk cartridge or the recording or reproduction of a disk;
- a door opening/closing detecting switch for sending a power supply turn-off signal in response to the opening of said loading door and a power supply turn-on signal in response to the closing of said loading door;
- and
- a power supply monitoring means for sending an operation inhibiting signal when the power supply is not turned off before the expiration of a predetermined time after the reception of a power supply turn-off signal from said door opening/closing detecting switch upon the opening of said loading door.
In a disk storage apparatus including means for selectively recording and reproducing information from a disk, the improvement comprising a moving storage unit for loading into said disk storage device through a loading door in an outer wall of said storage apparatus a storage pack for storing a predetermined number of disk cartridges;
- locking means for inhibiting opening of said loading door during the transfer of a disk cartridge and the recording and reproduction of a disk;
- a door opening/closing detecting switch for sending a power supply turn-off signal in response to the opening of said loading door and a power supply turn-on signal in response to the closing of said loading door;
- and
- a power supply monitoring means for sending an operation inhibiting signal when the power supply is not turned off before the expiration of a predetermined time after the reception of said power supply turn-off signal from said door opening/closing detecting switch upon the opening of said loading door.
