Further, if the key 61 is pulled out and the weight is not over, the storage box 14 is transferred to the transport cart 18 of the cart drive system 143 according to the storage box return flowchart shown in FIG. The item is returned to the original shelf booth 8.

However, if you forget to pull out the key 61,
The key removed notification buzzer 164 sounds and the dot matrix display 163 displays the message ``Please remove the lock.'' The operator notices this and only needs to pull out the key 61. Then, the storage box 14 is returned to the original shelf booth 8 in the same manner as described above.

In addition, if the weight is over, the overweight notification buzzer 165 will sound and the message ``Please remove some items from the storage box'' will be displayed, so the lid 1
5, take out some confidential items inside the storage box 14,
After reducing the weight of the storage box 14, close the lid 15,
If you remove the key 61, the original shelf booth 8 of the storage box 14 will be restored.
can be returned to.

In this manner, in the embodiment described above, it is possible to prevent the key 61 from being returned to the shelf booth 8 without forgetting to take it out from the lock 16. Also, damage to the shelf booth 8 etc. can be reliably prevented.

In addition, since the key 61 cannot be removed from the lock 16 unless the key 61 is locked, double checking of the ID card and the key 61 can significantly improve reliability regarding confidentiality.

Furthermore, to remove the key 61 from the lock 16, a key detection floodlight is installed on the underframe 30 separately from the storage box 14.
K ₁ and key detection light receiver K ₂ are used for detection, so each workbench 29 has only one detector K ₁ and K ₂ .
A pair is sufficient, making the device extremely simple and low in cost.

In the embodiment, the opening 30 of the underframe 30
Although we did not install a detector to detect this when the lid 15 of the storage box 14 is released from a, if we install one and try to return the storage box 14 with the lid 15 opened, this will occur. Notify the storage box 14
The return of the storage box 14 may be prohibited, and in this way, damage to the door 53 and the storage box 14 can be prevented.

Further, in the embodiment, the center unit 101 is provided with a center computer 110, and the main unit 103 is provided with a main computer 130.
However, the main computer 130 has the function of the center computer 110, and the center computer 110 in the center unit 101
may be removed.

Effects of the Invention As described above, in the present invention, when the user operates the storage box carry-in command means F, the user immediately removes the key J in order to detect that the key J has been forgotten and to warn the user. This prevents the user from forgetting to return home and prevents the items stored in the storage box A from being stolen.

In addition, the present invention prevents an accident in which the key J collides with the shelf booth B ₁ etc. as a result of transporting the storage box A into the shelf booth B ₁ without forgetting to remove the key J, the lock K, the key J, the lock K, etc. It is possible to prevent damage to shelf booth B1, _etc.

Furthermore, since storage box A is not transported into shelf booth _B1 with the key inserted into storage box A, it is possible to ensure that key J is returned to the user and to ensure the confidentiality of storage box A. Moreover, the interval between the shelf booths _B1 can be minimized according to the height of the storage boxes A, and the storage efficiency of the storage shelves B can be improved.

Furthermore, in the present invention, since the lid _A1 of the storage box A into which the key J is inserted can be opened and closed,
Storage reliability can be improved.

Moreover, in the present invention, it is possible to prevent the key J from being forgotten and to reliably return the storage box A to the original shelf booth _B1 , thereby preventing the next user from taking out and taking out the storage box A. It will not cause
