(Step S1). When the insertion of the holder body 10 is detected, the control unit of the driving unit 330 determines whether or not the user has an authority to exchange keys based on information input from the input unit 4. (Step S2).

  If it is determined at this determination that the user does not have the authority to exchange keys, the control unit of the driving unit 330 turns the drive motor 331 clockwise from the predetermined stop position shown in FIG. 7 as shown in FIG. By rotating, the engagement member 322 is disengaged from the holder body 10 (step S3), and the holder body 10 is pushed out from the insertion opening 30 during replacement by the urging force of the urging means 344. That is, when it is determined that the holder body 10 is not authorized to exchange the key after the holder body 10 is inserted into the insertion opening 30 at the time of replacement, the holder body 10 is replaced before the unlocking operation and the locking operation are performed. It is pushed out from the insertion opening 30. Extruding the holder body 10 in this way prevents erroneous insertion of the holder body 10 into the insertion opening 30 during replacement.

  On the other hand, if it is determined at step S2 that the user has the authority to exchange keys, the control unit of the driving unit 330 determines whether or not the insertion detection unit 340 detects the pressing of the holder body 10. (Step S4), and when pushing is detected, the unlocking operation is performed by rotating the drive motor 331 counterclockwise as shown in FIG. 12 from the stop position shown in FIG. 7 (step S5). . By this unlocking operation, the holder arm 11 can be freely attached to and detached from the holder main body 10, and the key held by the holder arm 11 can be exchanged.

  Next, the control unit of the driving unit 330 determines whether or not the insertion detection unit 340 detects the pressing of the holder body 10 (step S6), and when the pressing is detected, the state shown in FIG. A locking operation is performed by rotating the drive motor 331 clockwise so as to return to the state shown in FIG. 7 (step S7). By this locking operation, the attachment / detachment of the holder arm 11 with respect to the holder body 10 is restricted.

  After performing the locking operation, the control unit of the driving unit 330 engages with the holder main body 10 by rotating the drive shaft 331a of the drive motor 331 so that the state shown in FIG. The engagement of the member 322 is released (step S3), and the holder body 10 is pushed out from the insertion opening 30 at the time of replacement. That is, when the unlocking operation (step S5) is performed, the control unit of the driving unit 330 engages the engaging member 322 with the holder main body 10 until the locking operation (step S7) is performed, and is inserted at the time of replacement. The holder body 10 is restricted from being pulled out from the opening 30. By regulating the removal of the holder body 10 in this way, the key cannot be exchanged while the holder body 10 is pulled out from the insertion opening 30 at the time of exchange, and the key can be exchanged on the spot. . As a result, it is possible to clarify who and where the key was exchanged, and it is possible to more reliably manage key exchange.

  In such a key management device, when the unlocking operation is performed, the drive unit 330 engages the engaging member 322 with the holder body 10 until the locking operation is performed, and then inserts the holder from the insertion opening 30 at the time of replacement. Since the main body 10 is restricted from being pulled out, the key cannot be exchanged while the holder main body 10 is pulled out from the insertion opening 30 at the time of exchange, and the key can be exchanged on the spot. As a result, it is possible to clarify who and where the key was exchanged, and it is possible to more reliably manage key exchange.

  Further, the unlocking operation is performed by rotating the operation key 310 inserted into the key hole 101a of the cylinder body 101 so that the groove portion 100c of the exterior body 100 and the engagement groove of the cylinder body 101 communicate with each other. The locking operation is performed by rotating the operation key 310 inserted into the key hole 101a of the cylinder body 101 so that the groove portion 100c of the exterior body 100 and the engagement groove of the cylinder body 101 are not engaged. Since it is performed by rotating the cylinder body 101 so as to communicate with each other, the holder main body 10 is not inserted between the unlocking operation and the locking operation. Even if the key is pulled out from the key holder 1, the key cannot be attached to the key holder 1. As a result, the key exchange can be performed more reliably on the spot, and the key exchange management can be performed more reliably.
