Abstract

PURPOSE:To obtain a disc selecting and driving device supplying automatically a disc to a disc recording and reproducing device by using a drive band to select a disc so as to improve the storage density. CONSTITUTION:A ring drive band 11 is driven by a driver 12 and a position detector 16 supervises the number of turnings. When an object disc comes before a disc loader 15 corresponding to a disc recording and reproducing device 40 desired for recording and reproduction, the position detector 16 detects the disc, the disc loader 15 is activated to load the object disc to the disc recording and reproducing device 14. When the use of the loaded disc to the disc recording and reproducing device 14 is finished, the said disc is returned to a disc holder 13 in the converse order as above.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a disc selection drive device for selecting a necessary disc from among a large number of discs and recording and reproducing the disc.

Conventional configurations and their problems In recent years, large amounts of information are distributed and stored on multiple disks, and a specific disk containing the required information is automatically and quickly selected from among the disks. There is a demand for a device for selective reproduction. A conventional disk selection drive device will be described below with reference to the drawings. FIG. 1 shows a schematic diagram of a conventional disk selection drive device.

In the first prisoner, 1 is a disk, 2 is an ID disk holding stand, 3 is a disk mounting device, 4 is a disk recording and reproducing device,
5 is a position detection device. The operation of the disk selection drive device configured as described above will be described below. First, the disc holder 2 rotates to select three desired disc discs. The rotation angle is determined by the position detection device 5.
, is constantly monitored, and when the target disc comes in front of the disc mounting device 3, the rotation of the disc holding table 20 is stopped, the disc mounting device 3 mounts the target disc on the disc recording/reproducing device 4, and the disc is placed in front of the disc mounting device 3. Recording/reproduction is performed for. When the use of the disk mounted in the disk recording/reproducing device 4 is completed, the used disk is returned to the disk holder 2 in the reverse order of the above. However, in the above configuration, if the number of discs that can be accommodated is increased, the diameter of the disc holding stand 2 becomes larger and the device becomes larger, so there is a limit to the actual number of discs that can be accommodated. It also had the disadvantage that the density could not be increased.

Purpose of the Invention The purpose of the present invention is to increase the storage density of a large number of disks,
An object of the present invention is to provide a disc selection drive device that can automatically select and supply a disc to a disc recording/reproducing device.

Composition of the Invention The disk selection drive device of the present invention includes: a disk drive section in which a large number of disks and a disk holder are radially attached to the outer periphery of a belt-shaped annular drive band; a disk recording and reproducing device for recording and reproducing the disk; (the disc holder and the disc recording/reproduction) and ItI'a'l f@
Mea93□□. It is characterized by comprising an ear □ and a position detection device for detecting the position of the disk holder, and by making the annular drive band longer, it is possible to manage a larger number of recording and reproducing disks than before. It has the advantage of being selective.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 shows an embodiment of the present invention. Second
In the figure, 11 is an annular driving band, 12 is a driver, 13 is a disk and a disk holder, 14 is a disk recording/reproducing device, 15 is a disk mounting device, and 16 is a position detecting device. The operation of the disk selection drive device configured as described above will be described below. First, the annular drive band 11 is rotated by the driver 12, and the position detection device 1
6 monitors the amount of rotation. When the target disc comes in front of the disc mounting device 15 corresponding to the disc recording/reproducing device 14 for recording/reproducing, the position detection device 16 detects this, and the disc mounting device 16 operates to move the target disc to the disc. It is mounted on the recording/reproducing device 14. When the use of the disk mounted in the disk recording and reproducing device 14 is completed, the disk used in the reverse manner is returned to the disk holder 13. Furthermore, since there are a plurality of disk recording and reproducing devices 14 in this embodiment, there is an advantage that recording and reproducing can be performed on a plurality of disks at the same time.

FIG. 3 shows another embodiment of the invention.

In FIG. 3, 11 is an annular drive band, 12 is a drive element, and 13
14 is a disk recording and reproducing device, 16 is a disk mounting device, and 16 is a position detecting device, which are the same as those shown in FIG. Reference numeral 17 denotes a disk auxiliary holder, which serves to stably hold the disk below. Other operations are the same as in FIG. In this embodiment, in the case of FIG. 1, there are four disk recording and reproducing devices, and a second
Although eight devices are shown in the figure, any number of devices may be used, and they may be playback-only devices. Further, in this embodiment, the disk holders are installed at intervals, but a large number of disk holders may be installed without any intervals. The position and shape of the disk mounting device does not matter.

Effects of the Invention As described above, according to the present invention, when recording and reproducing a large number of discs, the drive band is used to select the disc, so a larger number of discs can be selectively implemented in a disc recording/reproducing device than before. In addition, by having multiple recording and reproducing devices, the disk can be shared between the disk recording and reproducing devices, and the disk can be used effectively.
Moreover, the search time can be reduced by mounting the necessary disk in the vacant disk recording/reproducing device that is closest to it. Furthermore, since the disk can be held horizontally when mounted on the disk recording/reproducing apparatus, it also has the advantage of stabilizing the performance of the disk recording/reproducing apparatus.
