[Industrial application field]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a door of a cartridge loading / unloading unit in a magnetic tape or optical disk library device.

As the size and performance of information processing systems have increased, the amount of data to be processed online has significantly increased, the work of handling magnetic tapes and optical disks has become complicated, and the cost has become enormous.

Under such circumstances, the need for a library device capable of automatically processing these has increased.

It is desired to improve the operation reliability of these library devices.

[Conventional technology]

As shown in the perspective views of FIGS. 4 and 5, the library device to which the present invention is applied has a cartridge 1 accommodating a plurality of information carriers such as magnetic tapes and optical disks at a predetermined position on the same plane. Further, a cylindrical storage cell 2 which is radially stored from the outer side surface and is rotatable about a vertical axis is provided, and the cartridge 1 is held on the outer side surface of the storage cell 2 by a hand 4 facing the predetermined position of the storage cell 2. Take it out of and move up and down,
It is mounted on the drive device 6 to read or write information, and then the cartridge 1 is loaded into the storage cell 2 in the reverse order.
And a handling mechanism 5 for returning to the original position.

That is, the magnetic tape cassette 1, as shown in the transverse sectional views of FIGS. 5 and 6 (a), stores a plurality of storage cells 2 that are evenly partitioned so as to radially store from the outer surface on the same plane. They are individually stored in a predetermined storage portion of the portion 2a.

At this time, in order to improve the storage efficiency, the upper right of the cartridge 1 is chamfered obliquely as shown in FIG.
The chamfered part is the partition wall for the space between the partition walls 2a 'that partition the storage part 2a.
The size is set so that the product can be normally stored as shown in the drawing only when it comes into contact with 2a '.

Therefore, as shown in the cross-sectional view of FIG. 6 (b), when the cartridge 1 is mistakenly stowed upside down by hand or the like, the upper right corner of the cartridge 1 hits the partition wall 2a 'and is stowed completely. However, a part of the front part thereof is projected from the outer circumference of the storage cell 2.

The storage cell 2 has a cylindrical shape as shown in FIG.
It is configured so that it can be rotated by a desired angle about a vertical axis 7 passing through the center.

On the other hand, the handling mechanism 5 only vertically moves the hand 4 and moves in the front-back direction as shown in FIG. 4, and the hand 4 is fixed in parallel so as to face the outer surface of the storage cell 2.

In the library device having such a configuration, the method of taking out the predetermined cartridge 1 from the storage cell 2 is as follows. First, the storage cell 2 is rotated by a desired angle and the desired cartridge 1 of the storage cell 2 is stored in the circumferential direction. The position of the handling mechanism 5
To match.

After that, the hand 4 of the handling mechanism 5 is moved up and down to a predetermined position so as to be aligned with the position where the cartridge 1 is stored, and gripping or magnetic attraction is performed.

Further, as shown in FIG. 4, the library device is entirely surrounded by a housing 8 from the viewpoint of maintenance, and the cartridge loading / unloading section is used to load or unload the cartridge 1 from the outside to the library device. It is designed to open and close the door 10 via 9.

In the figure, 11 is a data control unit, 12 is a device control unit, and 13 is a power supply.

[Problems to be solved by the device]

As shown in FIG. 6 (b), when the cartridge is not completely accommodated in the accommodating cell and the accommodating cell is rotated without knowing this, the protruding portion collides with the hand of the handling mechanism or the like, damaging either of them. There was a problem that the system itself was stopped.

The present invention is intended to detect abnormal charging of a cartridge.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, as shown in the top view of FIG. 1 (a), when the cartridge 1 is inserted into the storage cell 2 in an abnormal state, the cartridge 1 is projected from the storage cell 2. The door 16 of the cartridge inserting / ejecting section is provided with a pressing means 15 for pressing the above to detect an abnormal insertion.

[Action]

When inserting the cartridge into the storage cell 2, as shown in FIG. 1 (b), the pressure contact means 15 provided on the door 16 is retracted so as not to get in the way.

After the insertion, the pressing means 15 is projected for a predetermined length and the door 16 is closed.

When the cartridge 1 is normally stored, the pressing length of the pressing means 15 is set so as to simply contact or not to contact. Therefore, when the cartridge 1 is normally stored, the door 16 is closed. When the cartridge 1 is abnormally stored and the cartridge 1 is protruding, it collides with the cartridge 1 and does not close.

Due to this, it is possible to detect the abnormal storage of the storage cell of the cartridge 1.

〔Example〕

 1 to 3 show an embodiment of the present invention.

The same portions are denoted by the same reference numerals throughout the drawings.

In the present invention, as shown in the top view of FIG.
When the cartridge 1 is loaded into the storage cell 2 in an abnormal state, the door 16 of the loading / unloading section of the cartridge is provided with the pressure contact means 15 for detecting the abnormal loading by pressing the cartridge 1 protruding from the storage cell 2 into pressure. .

That is, the press-contact means 15 is an abutting member 17 rotatably attached to a door 16 provided in a cartridge loading / unloading portion of a housing 14 surrounding the library device, and the cartridge 1 is loaded into the storage cell 2. At the time of insertion, the butting member 17 is tilted and retracted as shown in FIG. 7B so that it does not get in the way.

When the insertion is completed, the abutment member 17 is erected and projected for a predetermined length to close the door 16 as shown in FIG.

The protruding length of the abutting member 17 is set to such a size that the tip may simply contact or may not contact when the cartridge 1 is normally stored. Therefore, as shown in FIG. As shown in the figure, when the cartridge 1 is normally stored, the door 16 is closed, but when the cartridge 1 is abnormally stored and the cartridge 1 is projected as shown in FIG.

As a result, abnormal storage of the storage cell of the cartridge 1 can be easily and accurately detected.

In FIG. 1A, reference numeral 18 denotes a support member that supports the abutting member 17 when it is erected, and for example, a lockable stay or the like is used.

FIG. 2 shows another embodiment of the pressure contact means 15. That is, the door
The 16 is provided with an abutting member 19 that can move back and forth, and is constantly urged by the coiled spring 20 to be projected from the door 16 at all times.

The entire length of the abutting member 19 is set so that when the cartridge 1 is abnormally accommodated as shown in FIG. 3B, the abutting member 19 is pushed by the protruding portion of the cartridge 1 and the rear end portion 19a thereof slightly protrudes from the door 16. Has been done.

Therefore, when the cartridge 1 is normally stored in the storage cell 2 as shown in FIG. 4A, even if the door 16 is closed, only the tip portion 19b of the abutting member 19 contacts the cartridge 1, and The end portion 19a does not protrude from the surface of the door 16.

As a result, abnormal storage of the cartridge 1 in the storage cell can be detected easily and accurately.

Incidentally, FIG. 3 is a perspective view of an essential part of FIG.

[Effect of device]

According to the present invention, abnormal storage in the storage cell of the cartridge can be detected easily and accurately, and the system can be made highly reliable.
