A location information acquisition unit (25) acquires location information for pointing a current location. A first transmission unit (21) sends, via a network to a management device (100), access request information used for requesting access to information acquisition units (23), (24), attached with the location information acquired by the location information acquisition unit (25). A first reception unit (22) receives, from the management device (100) via the network, access permission information or access prohibition information in response to the access request information. A control unit (20) leaves the information acquisition units (23), (24) prohibited to operate, if the access permission information has not been received yet by the first reception unit (22), and controls the information acquisition units (23), (24) to operate only for a predetermined duration to acquire information, upon reception of the access permission information by the first reception unit (22). |
