[Industrial application field]

The present invention relates to an information storage medium library device that stores a large number of information storage media such as optical disk cartridges or cartridge-type magnetic tapes, and extracts and stores/reproduces necessary information storage media.

When an information storage device handles a large amount of data, the amount of files increases, and a large number of information storage media are required to store the data.

For this reason, automatic warehouse (library) devices for processing and storing a large number of information storage media are provided on the market.

In such a library device, it is desired that the installation space is small (and that the system can be redundant in case of failure, and that the system can be configured without interruption).

[Conventional technology]

FIG. 4 is an explanatory diagram of the structure of a rotary drum type medium storage section of a conventional library device. In the figure, 1 is a hollow shaft that is rotatably provided, and 2 and 3 are above the shaft 1.

A top plate and a base plate are fixed below. A plurality of ranks 4 are arranged at equal intervals in the circumferential direction between the top plate 2 and the base plate 3, and each rack 4 stores a large number of information storage media 100 such as optical disk cartridges. There is. A rotation mechanism section 5 is provided in a portion of the shaft 1 below the base plate 3.

The rotation mechanism section 5 includes a drive motor 6 and a reducer 7, and the reducer 7 includes a worm 8 fixed to the output shaft of the motor 6, and a worm 8 fixed to the lower end 1a of the shaft 1. It consists of a worm wheel 9 that meshes with the worm wheel 9.

When the information storage medium in the rotating drum type medium storage section is transferred to and from the medium processing section (not shown), the motor 6
is rotated by a predetermined amount to make the desired rack 4 face an automatic transport section (not shown), and the desired information storage medium 100 is received and delivered by the automatic transport section.

The media processing unit redirects/distributes information to the supplied information storage medium.

C Problems to be Solved by the Invention] However, in the above-mentioned conventional structure, the rotation mechanism section 5 is disposed below the storage section main body (the part above the base plate 3), and the central part of the storage section main body cannot be utilized. I was wasting it.

For this reason, it has been difficult to increase the efficiency of implementing the information storage medium as a device.

An object of the present invention is to provide a library device that can improve storage medium mounting efficiency, achieve high performance, large capacity, and save space.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention includes a rotating drum-type medium storage section that houses a large number of information storage media around the periphery and rotates by being driven by a rotation mechanism section including a speed reducer, and at least one of the information storage media. In a library device for information storage media, the information storage medium has a media processing section that performs playback, and an automatic transportation section that transports the information storage medium and transfers the information storage medium between the media storage section and the media processing section. , at least a reduction gear of the rotation mechanism section is arranged in a center of the medium storage section.

[For production]

Since at least the speed reducer of the rotating mechanism section is arranged in the center of the medium storage section, the space that was conventionally required below the main body of the medium storage section for arranging the rotating mechanism section can be used as the information storage medium storage space. . Therefore, a rotating drum type medium storage unit that can store a large number of media and has a short height dimension is realized. Furthermore, when the media processing section is disposed immediately below the rotating drum type media storage section, the number of mounted media processing sections can be increased.

Embodiment] The present invention will be described in detail below with reference to FIGS. 1 to 3.

FIG. 1 is a perspective view of the inside of the library apparatus of this example as seen from the front side, and FIG. 2 is a perspective view of the inside of the library apparatus as seen from the back side. is an automatic transport section.

As shown in detail in FIG. 3, the rotating drum type medium storage unit 11 includes a hollow shaft 14, and an upper plate 15 and a base plate 16 fixed above and below the shaft 14. A plurality of racks 17 are arranged at equal intervals in the circumferential direction between the base plate 16 and the base plate 16.

Each rack 17 has a large number of information storage media 100.
is stored. The center of the base plate 16 is formed so as to protrude upward, thereby forming a recess 18 in the center portion of the base plate 16. The rotating mechanism section 19 that drives the rotating drum type medium storage section 11 includes a speed reducer 20 installed in the recess 18 and connected to the lower end of the shaft 14, and a motor 21 (second 1), and the rotation of the motor 21 is transmitted to the speed reducer 20 via the timing belt 22. The reducer 20 shown in FIG. 3 uses a Harmonic Drive manufactured by Harmonic Drive Co., Ltd., and has a compact external shape, so that it can be installed in the recess 18.

The medium processing unit 12 is of a well-known configuration 1 for reproducing or recording information on the supplied information storage medium 100, and is disposed below the rotating drum type medium storage unit 11.

The automatic transport section 13 performs the work of storing the information storage medium 100 inputted from the medium input port 23 into the rotating drum type medium storage section 11, and the operation of storing the information storage medium 100 inside the rotating drum type medium storage section 11. The work of discharging the information storage medium from the outlet 24 and the receiving of the information storage medium between the rotating drum type medium storage section 11 and the medium processing section 120 are well-known transfer operations.

When a plurality of devices having such a configuration are installed, although not shown in the drawings, they are installed side by side in the horizontal direction, or two devices are installed back to back and installed in the horizontal direction.

〔Effect of the invention〕

As described above, according to the present invention, at least the reducer of the rotating mechanism section is arranged in the center of the rotating drum type medium storage section, so that You can use the space of your subordinates. Therefore, it is possible to increase the number of information storage media stored and the number of media processing units installed, which greatly contributes to improving the performance of the library device.
