[0020] The storage unit 110 is implemented by an HDD (Hard Disk Drive), a flash memory, a RAM (Random Access Memory), a ROM (Read Only Memory), etc. The storage unit 110 stores the luggage storage flag F, the log R, and the subscriber identification information SID. The luggage storage flag F is information indicating whether or not luggage is stored in the storage box 100. For example, when luggage is stored in the storage box 100, the luggage storage flag F is turned on, and when no luggage is stored in the storage box 100, the luggage storage flag F is turned off. The log R sequentially stores the subscriber identification information of the mobile terminal 200-1 held by the user U1 who unlocked the storage box 100 and the subscriber identification information of the mobile terminal 200-2 held by the user U2. Here, the log R may store the subscriber identification information of the mobile terminal 200-1 held by the user U1 who unlocked the storage box 100, the subscriber identification information of the mobile terminal 200-1 held by the user U2, and the time information when the unlocking was performed in association with each other. The subscriber identification information table SIDT is a list of subscriber identification information of the mobile terminal 200 held by the user who is permitted to unlock the storage box 100. For example, a subscriber information notification including one or more pieces of subscriber identification information of the mobile terminal held by the user who is permitted to unlock the storage box 100 is transmitted to the storage box 100, and the first communication unit 102-1 receives the subscriber information notification. The control unit 104 receives the subscriber information notification received by the first communication unit 102-1 and acquires one or more pieces of subscriber identification information included in the received subscriber information notification. The control unit 104 stores the acquired one or more pieces of subscriber identification information in the subscriber identification information table SIDT of the storage unit 110.

[0021] The electric lock 108 is a lock that can unlock the door with key information without using a key. In the present embodiment, as an example, the description will continue with the case where the electric lock 108 is automatically locked (secured) when the door is closed after being unlocked. The control unit 104 acquires the key information and the subscriber identification information received by the first communication unit 102-1, and unlocks the electric lock 108 based on the acquired key information.

The second communication unit 102-2 receives the key information and the subscriber identification information transmitted by the mobile terminal 200-2. The control unit 104 acquires the key information and the subscriber identification information received by the second communication unit 102-2. The control unit 104 determines whether the acquired subscriber identification information is stored in the subscriber identification information table SIDT of the storage unit 110. If the acquired subscriber identification information is not stored in the subscriber identification information table SIDT, the control unit 104 performs a predetermined error process without unlocking the electric lock 108. When the acquired subscriber identification information is stored in the subscriber identification information table SIDT, the control unit 104 unlocks the electric lock 108 of the door based on the acquired key information. The control unit 104 stores the subscriber identification information in the log R of the storage unit 110. Here, the control unit 104 may acquire time information and store the subscriber identification information in the log R of the storage unit 110 in association with the acquired time information. By storing the subscriber identification information of the mobile terminal 200-2 held by user U2 in the log R of the storage unit 110, if the storage box 100 has been vandalized, the subscriber identification information of user U2 who unlocked the electric lock 108 of the storage box 100 can be obtained by referring to the log R. Therefore, it is possible to identify who vandalized the storage box 100. User U2 takes out the luggage stored in the storage box 100 and closes the door.
