Abstract

PURPOSE:To take out a tape cartridge by a transport mechanism without a cartridge push-in mechanism becomes a stopper of the tape cartridge in the cartridge throw-in device of a magnetic tape device with an automatic storage box. CONSTITUTION:In a cartridge throw-in device 101, when a transport mechanism takes out a tape cartridge 3 from a cartridge take-out port 7, a movable stopper mechanism 5 is provided at the location where the tape cartridge 3 is prevented to move back in the direction towards a cartridge insertion port 6. The mechanism 5 has a movable section which is installed and being freely turnable with respect to the hinge fixed on the cartridge throw-in device 101. This movable section springs up when the cartridge 3 moves toward the cartridge take-out port and when the cartridge 3 passes, the section goes back to an original position to prevent the cartridge having a move back motion.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic storage magnetic tape device, and more particularly to an automatic storage magnetic tape device having a cartridge loading device.

[0002]

2. Description of the Related Art A magnetic tape device with an automatic storage has a storage shelf for storing a tape cartridge, a read / write mechanism for writing / reading information to / from the tape cartridge, and a tape cartridge to be stored inside the main unit. It is provided with a cartridge loading device for temporarily storing, a transfer mechanism for transferring the tape cartridge between the storage rack, the reading / writing mechanism and the cartridge loading device.

FIG. 3 shows this conventional cartridge loading device. In the diagram (a), the cartridge loading device 10
0 has a cartridge pushing mechanism 2 for pushing the tape cartridge 3 from the cartridge insertion opening 6 toward the cartridge ejection opening 7. The cartridge pushing mechanism 2 is
When the tape cartridge 3 is inserted from the cartridge insertion opening 6, it is in a position where it does not interfere with the insertion as shown in the drawing (b), and after the insertion is completed, the tape that has been inserted as shown in the drawing (a). When the tape cartridge 3 located closest to the cartridge outlet 7 in the cartridge 3 is pushed to the cartridge outlet 7 and the pushed tape cartridge 3 is taken out by the transfer mechanism, the tape cartridge 3 is directed toward the cartridge insertion opening 6. Stop at a position that prevents you from moving backward. In addition, the transfer mechanism
It has a hand push lever 4, and when it is detected by the hand push lever 4 that the tape cartridge 3 is present in the cartridge ejection port 7 without retracting in the direction of the cartridge insertion port 6 and is ready for ejection, 3 is taken out.

[0004]

In this conventional magnetic tape device with an automatic storage, since the cartridge pushing mechanism of the cartridge loading device is stopped at a position that prevents the tape cartridge from retracting toward the cartridge insertion port, If the tape cartridge is additionally loaded before all the tape cartridges in the cartridge loading device are exhausted, there is a problem that the transfer mechanism cannot take out the tape cartridge until the pushing of the additionally loaded tape cartridge is completed. ..

[0005]

SUMMARY OF THE INVENTION A magnetic tape device with an automatic storage according to the present invention comprises a storage shelf for storing a tape cartridge, a read / write mechanism for writing / reading information to / from the tape cartridge, and an internal main device. A cartridge storage device for temporarily storing a tape cartridge to be stored therein, and an automatic storage box having a transfer mechanism for transferring the tape cartridge among the storage rack, the read / write mechanism and the cartridge input device. In the attached magnetic tape device, the cartridge loading device is provided with movable stopper means for preventing the tape cartridge from retracting toward the cartridge insertion port when the transfer mechanism takes out the tape cartridge.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a cross sectional view of a cartridge loading device according to a first embodiment of the present invention. The cartridge loading device 101 of this embodiment has a hinge at a position that prevents the tape cartridge 3 from retracting toward the cartridge insertion port 6 when the transfer mechanism (not shown) removes the tape cartridge 3 from the cartridge ejection port 7. A movable stopper mechanism 5 having a movable portion which is supported by the main body of the feeding device via the rotary body and rotates within a certain angle is provided. Movable stopper mechanism 5
When the tape cartridge 3 is transferred in the cartridge loading device 101 toward the cartridge outlet 7 and passes under the movable stopper mechanism 5, the movable part of FIG.
As shown in (b), when the tape cartridge 3 is pushed up to the position where it does not hinder the transfer, and the tape cartridge 3 passes under the movable stopper mechanism 5 and is transferred to the cartridge ejection port 7, As shown in FIG. 1A, the tape cartridge 3 moves to a position that prevents the tape cartridge 3 from retracting in the direction of the cartridge insertion opening 6, that is, to the rear end cutout portion of the tape cartridge 3 by its own weight or the force of a spring.

As a result, even if the cartridge pushing mechanism 2 does not stop at a position that prevents the tape cartridge 3 at the cartridge outlet 7 from retracting in the direction of the cartridge insertion port 6, the transfer mechanism is at the cartridge outlet 7. The tape cartridge 3 can be detected by the hand push lever 4 and taken out.

FIG. 2 is a cross-sectional view of a cartridge loading device according to the second embodiment of the present invention. The cartridge loading device 102 of the present embodiment controls the cartridge presence / absence detection device 8 that detects whether or not the tape cartridge 3 is present in the cartridge ejection port 7, and the stopper 9 according to the detection result of the cartridge presence / absence detection device 8. A stopper controller (not shown), a position that does not hinder the transfer of the tape cartridge 3 in the cartridge loading device 102, and that the tape cartridge 3 retracts toward the cartridge insertion opening 6 when the transfer mechanism takes out the tape cartridge 3. And a stopper 9 that moves between the position and the position that hinders. When the cartridge presence / absence detection device 8 detects that the tape cartridge 3 does not exist in the cartridge ejection port 7, the stopper 9 moves to a position (upper side in the drawing) that does not hinder the transfer of the tape cartridge 3 in the cartridge loading device 102, When it is detected that the tape cartridge 3 is present, stopper control is performed so as to move the tape cartridge 3 to a position that prevents the tape cartridge 3 from retracting toward the cartridge insertion port 6 when the tape cartridge 3 is taken out, that is, to the rear end cutout portion of the tape cartridge 3. Controlled by the department. This produces the same effect as that of the first embodiment.

[0010]

As described above, according to the present invention, the movable stopper means is provided at a position that prevents the transfer mechanism from retracting toward the tape cartridge insertion port when the transfer mechanism takes out the tape cartridge from the cartridge loading device. Even if the pushing mechanism does not stop at a position that prevents the tape cartridge from retracting toward the cartridge insertion port, the transfer mechanism can take out the tape cartridge at the cartridge ejection port at any time.
