Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a disc exchange device that stores a plurality of discs, which are disc-shaped information recording media, and automatically loads any disc into a recording or playback device. be.

Conventional configurations and highlights There are playback-only devices or recording/playback devices that use disks as a means to file video information and document information and to snoop on each piece of information at high speed. Generally, a single disk is manually replaced and used, so the amount of information that can be processed at one time is limited. In response, there is a demand in various fields for an information processing system that can file large amounts of information and search at high speed. For this purpose, a plurality of discs are stored, and any disc is loaded into a player such as a recording/playback device that automatically reproduces all information or records/reproduces information at high speed, and records a predetermined information sound σf or predetermined information. This is necessary. An example of a device for automatically exchanging a plurality of such large-diameter disks is the autochanger device for audio records shown in FIG. In FIG. 1, the disks 2, 3, 4.5 are held coaxially. For example, if you want to play another disc 4 instead of disc 2 that is being played/l: on player 1, put disc 3 on top of disc 2 on player 1, disc 4 on top of disc 3, and so on. Therefore, it is not possible to select and play discs one after another.

Moreover, as shown in FIG. 2, a plurality of disks 6,
7, 8i A magnetic disk provided with a disk driving means 11 that rotates simultaneously and a detecting means 10 consisting of a pickup for signal recording and reproduction provided corresponding to each disk 6, 7, 8 on the same axis 9. There are device-type ones. In this case, it is necessary to increase the rotation accuracy in order to maintain stable recording and playback characteristics of each disk, but in order to do so, the total number of disks must be limited, and the disk drive means must also correspond to the number of disks. It must be the same size. In addition, replacing the disk is a disk unit, in this case,
It is necessary to exchange three disks (6, 7, and 8), making it difficult to replace just one arbitrary disk. Furthermore, since a pickup for signal detection is required for each disk, when the number of disks increases, the structure of the pickup becomes complicated in accordance with the number of disks. Furthermore, it becomes difficult to stabilize the recording and reproducing characteristics between each pickup and the disk. Furthermore, the transport means 12 of the detection means 1o for high-speed searching requires high-output driving in order to stably transport the plurality of detection means 10, which limits the number of disks.

As mentioned above, with conventional disk exchange devices, it has been difficult to search for arbitrary disks at high speed and to reduce the size of the device.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, the present invention provides a disk exchange device that can automatically and quickly search for a desired disk from a plurality of disks and that can be miniaturized.
