In the case of this imaging, in this embodiment, imaging is performed while the main body case 20 is turned.
- the control unit 37 transmits an imaging instruction signal that is an external signal instructing imaging with the camera 35 transmitted from the external device 16 via the network 15. Whether the wireless LAN device 36 has received the data via the access point 14 is determined, for example, in real time or every predetermined time (step 1).
