  The present invention relates to a key management system for managing elevator maintenance keys.

Conventionally, a key box for storing an elevator maintenance key is provided for each elevator installation site. Each key box stores a different maintenance key for each installation site, and the doors of the key boxes are locked with a common key.
A person who performs maintenance work on the elevator opens the door of the key box with a common key, and takes out the maintenance key stored in the key box.
Therefore, if you do not carry this common key, you cannot open the door of the key box. For example, even when sudden maintenance work is required, you can perform maintenance work. There was a problem that it was not possible.

In order to solve this problem, for example, it is conceivable to open the key box door using a personal identification card (hereinafter referred to as “ID card”) such as an employee ID card carried by all employees.
This solves the problem that the elevator maintenance work cannot be performed because the common key is not carried.
Here, as an invention for taking out a key stored in a key box using an ID card, for example, the following can be cited.

A conventional key management device reads the contents of an ID card (magnetic card or IC card) with a card reading means, and when the contents of the ID card satisfy a predetermined authentication condition, covers the device and opens a protective door that protects the equipment. Locked. In addition, when predetermined necessary information is input by the display input means with the ID card inserted in the card reading means, the key cover that covers and protects the key is unlocked and the key can be taken out (for example, Patent Document 1).
Here, after the key is taken out, the key cover is locked by closing the key cover, and the protective door is locked by closing the protective door and removing the ID card.
