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.
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.
Since the key detection light receiver K ₁ and the key detection light receiver K ₂ are used for detection, only one pair of these detectors K ₁ and K ₂ is required for each workbench 29, which makes the device extremely simple and the cost low.

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.
