A communication control unit performs communications with an external device via a first wireless communication unit of which communication distance is short and which is capable of performing high-speed communications or a second wireless communication unit of which communication distance is long compared with the first wireless communication unit and which is capable of performing low-speed communications. A communication state judging unit judges a communication state of the communications with the external device via the first wireless communication unit or the second wireless communication unit. The communication control unit performs switching between the communications with the external device via the first wireless communication unit and the communications with the external device via the second wireless communication unit based on the communication state judged by the communication state judging unit and/or a transmission data amount to be transmitted to the external device.
