[Embodiment] An embodiment of the present invention will be described below in detail with reference to the drawings.

First, FIG. 1 shows the internal structure of the disk library device, and FIG. 2 shows a cross section of the disk library device.

As is clear from the figure, a partition wall 2 is provided inside the main body housing 1 of the disk library device.
It is divided into compartments. The chamber 3 on one side of the partition wall 2 is equipped with a cartridge housing portion 11 made of a shelf for housing the cartridges 10 containing optical disks in multiple stages, and the cartridge 10 is added to the lower position of the cartridge housing portion 11. An inlet mechanism section 12 is provided for performing or exchanging. Further, below the inlet mechanism portion 12, the disk drive devices 13 are mounted in a stacked state of a plurality of stages (six stages in this embodiment).

The cartridge 10 accommodated in the cartridge accommodating portion 11 is taken out, mounted on the disk drive device 13, and the cartridge 10 after the drive is re-accommodated to the original position in the cartridge accommodating portion 11 by partition walls 2. In the chamber 4 on the other side, the cartridge holder 20
Is provided. Thus, in order to enable the transfer of the cartridge 10 between the cartridge holder 11 and the disk drive device 13 and the cartridge holder 20, the cartridge holder 11 has an opening 11a for inserting and removing the cartridge 10. It faces the chamber 4, and the cartridge insertion / removal port of the disk drive device 13 is also in this chamber 4.
It is designed to be installed so that it faces inside.

The cartridge holder 20 can be moved up and down along the elevating rod 21 as shown by the arrow in FIG. As a result, first, the cartridge holder 20 is displaced to a height position where the predetermined cartridge 10 is accommodated in the cartridge accommodating portion 11, and the cartridge 10 is mounted on the cartridge holder 20 by a cartridge transfer mechanism (not shown). Disk drive device with 20 stages
The disk drive device 13 is moved to a position facing any one of 13 and is mounted in the disk drive device 13 as it is or after being inverted. When the drive of the disk built in this cartridge 10 is finished, the cartridge 10
The cartridge holder 11 by the cartridge holder 20.
Are stored again in place at.

Here, the chamber 4 and the cartridge accommodating portion 11 that opens into the chamber 4, and the cartridge insertion / ejection port of the disk drive device 13 must be kept in an extremely clean atmosphere without dust or other suspended matter. On the other hand, the disk drive device 13 installed in the chamber 3 needs to be properly taken out from the mounting position for repair and inspection. In addition, at the bottom of the cartridge accommodating portion 11, a cartridge insertion opening is provided at the rear for replacing or adding the cartridge 10.
An inlet mechanism section 12 including 12a is provided. Therefore, in order to enable operations such as taking out and reattaching the disk drive device 13 and inserting the cartridge 10 into the inlet mechanism section 12, the back side of the main body housing 1 is an opening / closing door 1a.
