In the case of the mobile phone 20-10, the video camera 20-11, and the digital camera 20-12, the user may turn on the power manually or automatically when a radio signal is received by the RFID tag 40-1. Alternatively, the own battery may be turned on.

  Next, it is determined whether or not the identification information and the summary data are received (step S122). When the identification information and the summary data are received, the received identification information and the summary data, the self-identification information, The summary data is collated (step S124). Next, it is determined whether or not both match (step S126). If both do not match, the processing ends. On the other hand, if both match, the remaining battery level detection unit 40-6 acquires the remaining battery level (step S128), and returns the received identification information, summary data, and the acquired remaining battery level (step S130). ), The process ends.

  As described above, when only summary data is transmitted / received, original data corresponding to a plurality of external recording devices may exist. Similar to the second embodiment described above, for example, the user of the digital camera 30 knows in which external recording device 20-1 to 20-6, 20-10 to 20-12 the data related to “excursion” is stored. If desired, the user selects the outline data “excursion”. In this case, if there are a plurality of external recording devices in which data registered as “excursion” is stored in the comment tag, all areas where the corresponding external recording device is located are highlighted.

  According to the third embodiment described above, the digital camera 30 transmits the identification information and summary data for identifying the external recording device storing the original data of the selected thumbnail, and the identification information and the summary data. If there is a reply from an external recording device that matches, the external recording devices 20-1 to 20-6 and 20-10 to 20-12 that are scattered are displayed on the screen on the basis of the received intensity. Since the area corresponding to the distance from the recording apparatus is highlighted, the user can easily confirm where the external recording apparatus storing the desired original data is. Further, since the remaining battery capacity of the corresponding external recording device is also displayed, it can be easily confirmed whether or not battery replacement or charging is necessary.
