Description

The present invention relates to a collective type optical disc device, and more particularly to a storage shelf for storing a plurality of cartridges containing optical discs,
1 selected from the cartridges stored in this storage shelf
The present invention relates to a collective type optical disc device having a drive device for reading information from or writing information to an optical disc in each cartridge.

[Conventional technology]

A conventional collective type optical disk device is equipped with a cartridge 10 having a rectangular parallelepiped shape as shown in FIG. 3 and is provided with a fourth disk for reading and writing information on an optical disk contained therein. As shown in the figure, a storage shelf 5 for holding a plurality of cartridges 10 in a horizontal state and vertically loading and storing the same at a constant interval, and a storage shelf 5 disposed below and adjacent to the storage shelf 5. Drive device for reading or writing information on the optical disc built into the disc
6a and 6b, and the storage rack 5 and the drive devices 6a and 6b are arranged in close proximity to each other, and the storage rack 5 and the drive device 6a or Cartridge 10 to 6b
And a transport mechanism (not shown) for transporting.

[Problems to be Solved by the Invention]

Since the conventional collective type optical disk device as described above has a structure in which one storage rack and two drive devices are stacked, it is necessary to cope with an increase in the number of cartridges stored and an increase in the read / write capability. Therefore, it is necessary to increase the number of installed collective optical disk devices. Even if the number of stored cartridges or the amount of read / write capability is small, the same measure is required. In such a case, large equipment cost and floor area are required for installation, which is cost-effective. It has the drawback of being low.

[Means for Solving the Problems]

The collective type optical disc device of the present invention has a rectangular parallelepiped outer shape, and has a plurality of shelf plates provided on the inner surface at equal intervals for storing a plurality of optical disc cartridges containing optical discs in a horizontal state. It has a side plate and a first projecting portion provided outside the side plate in a vertically protruding state, and mounting holes are provided at two locations above and below the first projecting portion,
A plurality of storage shelves provided with a guide shaft between the mounting holes, and a second overhang portion on the left and right side surfaces at a position corresponding to the first overhang portion of the storage shelves, The second overhanging portion is provided with the two mounting holes of the first overhanging portion and the mounting holes corresponding to the guide shaft and the guide shaft, and the height dimension is equal to or more than the height dimension of the storage rack. And, at least one drive device is provided in which a loading port opened horizontally is provided on the front surface, and the height position of the loading port is equal to the height position of the second shelf plate from the top of the storage shelf. I have it.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG.
It is a perspective view which shows the detail of the storage shelf of the Example of a figure.

The optical disk cartridge used in the embodiment of FIG.
As shown in FIG. 3, an optical disk is built in a cartridge 10, which has a rectangular parallelepiped shape and has concave grooves 11 for holding on both side surfaces thereof.

In this embodiment, as shown in FIGS. 1 and 2, a plurality of storage shelves 15a to 15d (collectively referred to as storage shelves 15) are stacked, and each storage shelves 15 holds the cartridge 10 horizontally. Shelf 16a on the inside of the left and right side plates
~ 16e and 17a ~ 17e (Shelf board 16
Or shelf boards 17) are provided at equal intervals. On the other hand, at the corresponding positions on the outer surfaces of both side plates, an overhanging portion 14 having two mounting holes 18 for screwing vertically and a positioning guide shaft 19 provided at the center thereof is provided. The drive devices 20a and 20b are for reading or writing information on the optical disc in the cartridge 10, and are arranged in a stack below the lowest storage shelf 15d. At the front of each drive device 20a and 20b, there are provided inlets 21a and 21b for inserting the cartridge 10, respectively, and at the same position as the overhang portion 15 of the storage shelf 15 on the outside of each side surface. Overhangs 22a and 22b are provided. Each of the overhanging portions 22a and 22b is provided with two upper and lower mounting holes and a guide shaft between them at the same position as the overhanging portion of the storage rack 15. The height H1 of the storage shelf 15 is determined by
The height of the second plate shelf 16b and 17b is the same as the height H3 of the input ports 21a and 21b. The transport mechanism (not shown) is a cartridge
The cartridge 10 is transferred to the drive device 20a or 2 by performing the forward and backward and vertical movements and the reverse operation of the front and back.
Since it is inserted into the input ports 21a and 21b of 0b, it is arranged close to the storage shelf 15 and the drive devices 20a and 20b.

Next, the operation of the collective optical disk device configured as described above will be described.

The cartridge 10 stored in the storage shelf 15 is transferred to the input port 21a or 21b of the drive device 20a or 20b by the transfer mechanism. The drive device 20a or 20b pulls in the transferred cartridge 10 from the input port 21a or 21b, reads or writes information from or into the optical disk contained therein, and finishes those operations. Then, the cartridge 10 is discharged to the outside from the input port 21a or 21b, and the discharged cartridge 10 is transferred to the storage shelf 15 again by the transport mechanism and stored therein.

The storage shelves and the drive devices can be mounted in arbitrary numbers below a predetermined number by fixing the storage shelves and the drive devices to the columns by means of upper and lower mounting holes with reference to the guide shaft. Therefore, set the above predetermined number to a large value in advance,
It is possible to easily increase the storage capacity of the optical disk cartridge and the read / write capability of the drive device by limiting the number of mounted devices to the required minimum number and adding more as necessary.

〔The invention's effect〕

As described above, the collective optical disc device of the present invention has a plurality of storage shelves and a plurality of drive devices stacked and installed, and the mounting holes and the guide shafts are arranged at the same positions on the side surfaces thereof. By providing the section, it is possible to easily realize an increase in the number of stored optical disk cartridges and an increase in read / write capability. Therefore, it is possible to deal with the addition of storage shelves or drive devices only without increasing the number of collective optical disk devices installed as in the past, so it is possible to reduce equipment costs.
Further, there is an effect that the floor area used can be the same as the conventional one. Further, when the shelf plate of the storage shelf is damaged, the storage shelf can be repaired simply by exchanging the storage shelf, so that the repair cost can be reduced.
