Abstract

PURPOSE:To increase the number of sheets of cartridges to be stored, and to speed up access by providing a carrier with the rotating device of the cartridge approximately at the central part of a radial shape so as to be capable of moving vertically. CONSTITUTION:When the cartridge 6 containing an optical disk is inserted to a charting and discharging port 5, a charging and discharging mechanism part 3 moves to the position of the charging and discharging port 5, and receives the cartridge 6. Thus, the mechanism part 3 moves to the position of a rack 11a. Next, when a carrying device 13 rotates and in addition, lifts a carrier 4 so as to correspond to the mechanism part 3, the carrier 4 takes out and carries the cartridge 6 to the position of an optical disk device 2 or the rack 11. In this case, at the time to carry it to the rack 11b-11f other than the rack 11a, the carrier 4 is revolved in a direction to minimize the angle of rotation by the operation of the device 13 so that the carrier 4 corresponds to the desired rack 11b-11f in minimum time. Hereafter, a similar operation is repeated between the racks 11a-11f and the device 2.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is a large-capacity disk device, that is, a disk capable of recording and reproducing information is stored in a cartridge, and the cartridge is further stored in a rack in the vertical direction. The present invention relates to a large-capacity disk device in which the cartridge is loaded into and taken out of the disk device using a conveyor.

[Conventional technology]

The one shown in Fig. 3 is, for example,
The conventional large 8 shown in No. 7! FIG. 2 is a side cross-sectional view showing the optical disk device.

In the figure, reference numeral (1) indicates a rack for vertically storing cartridges containing disks, (2) indicates an optical disk device for recording and reproducing the disk, and (3) indicates a rack for storing cartridges inside and outside the large-capacity optical disk device. (4) is a transport mechanism that transports cartridges between the rack (1), the optical disk device (2), and the loading/unloading mechanism (3), and (5) is a transport mechanism that greatly (cars that are moved in and out of the capacity optical disk device)
This is the IJ edge supply/discharge port, and (6) is the record.

This is a cartridge that contains a playable disc.

Next, the operation of the above conventional device will be explained.

The operator inserts the cartridge (6) into the supply/discharge mechanism section (3), and the cartridge (6) is picked up by the supply/discharge mechanism section (3), and then pulled to the position of the rack (1) in that state.
It's crowded.

The transport machine (4) moves to the position of the supply/discharge mechanism section (3),
Cartridge (6) held in the supply/discharge mechanism section (3)
from the supply/discharge mechanism section (3).

The transport machine (4) that has extracted and gripped the cartridge (6) moves to the position of the rack (1) or optical disk device (2), and stores the cartridge (6) in the rack (1) or stores the optical disk device. The device is installed in device (2).

Thereafter, if necessary, the cartridge (6) can be placed in the rack (
1) and the optical disk device (2), a transfer machine (4) performs loading and unloading.

[Problem to be solved by the invention]

Since conventional large-capacity disk devices are configured as described above, the number of racks that store cartridges can only be arranged in two rows, and it has been difficult to increase the number of cartridges that can be stored.

However, as the capacity increases, there is a strong demand for increasing the number of cartridges that can be stored, and this has created the problem of increasing the number of cartridges that can be stored.

This invention is like the above! This was done to solve the problem, increasing the number of cartridges that can be stored,
Moreover, it is an object of the present invention to obtain a large-capacity disk device 4 in which the access speed is not too slow.

[Means to solve the problem]

A large-capacity disk device according to the present invention has three or more sets of racks for vertically storing cartridges for storing disks arranged in a substantially equiangular radial pattern with the cartridge loading/unloading side facing inside. A conveyor is provided approximately at the center of the radial line, which is capable of vertical movement and is equipped with a car (IJ) rotation device.

[For production]

In the large-capacity disk device of the present invention, a cartridge held in a transporter is rotated in an arbitrary direction by a rotating device, and accessed by raising and lowering it facing a target rack among racks arranged radially. Do this.

〔Example〕

The present invention will be explained below based on the drawings showing one embodiment thereof.

FIG. 1 is a side cross-sectional view of a large-fit optical disk device according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line 1--2 in FIG.

Also, in the figure, symbols (2) (3) (41(s) (6
) are the same as or equivalent to those indicated by the same reference numerals in the conventional device.

In the figure, reference numeral (11) denotes a rack that stores a plurality of cartridges (6) for storing optical discs in the vertical direction. For example, as shown in FIG. The installed racks (11a) (11
b) (11c) (lid) (lle) (llf).

Further, (12) is a conveying device, and the conveying machine (4)
is configured to be movable up and down like the conventional device, and is also configured to be rotatable by a rotation drive unit (13) serving as a rotation device for the cartridge (6), thereby rotating the cartridge (6). ing.

Note that details of the drive system will be omitted. Further, each of the operating parts described above is operated by a drive mechanism (not shown) and controlled by a control device (not shown).

Next, the operation of the above embodiment will be explained.

When the cartridge (6) containing an optical disk is inserted into the cartridge supply/discharge port (5), the supply/discharge mechanism section (3) moves to the cartridge supply/discharge port (5) and receives the cartridge (6). take.

After removing the IJ screw (6), remove the supply/discharge mechanism (3).
) moves to the rack (lla).

Next, when the transport device (13) rotates and raises the transport machine (4) to make the transport machine (4) correspond to the supply/discharge mechanism section (3), the transport machine (4) moves to the supply/discharge mechanism section (3). 3) is taken out and transported to the optical disk device (2) or the rack (11) where it is stored.

In this case, racks (11b) other than rack (lla)
When transporting to (IIN), the rotational drive unit (13) operates to move the transporter (4) to the minimum rotation angle, that is,
Rotate it in a direction that is 180 degrees or less no matter how big it is,
Therefore, the conveyor (4) carries the desired racks (llb) to (l
lf) with the minimum time.

From now on, the racks (lla) to (llf) and the optical disk unit f
The same thing is repeated with it(2).

In the above embodiment, the cartridge (6) in the conveyor (4) is rotated by the rotation of the conveyor (4) by the rotary drive unit (13)K, but the present invention is not limited to this, and any means, For example, a cartridge (
6) may also be used.

〔Effect of the invention〕

As described above, according to the present invention, three or more sets of racks for storing cartridges for storing disks are arranged in substantially equal radial directions with the cartridge storing and ejecting sides facing inside, and Since it is equipped with a conveyor that can move up and down and has a cartridge rotation device located almost in the center of the disk, the number of cartridges that can be stored in the disk storage can be greatly increased. , respond in the minimum amount of time,
Therefore, it is possible to obtain a large-capacity disk device with quick access.
