說明書

Note that the configuration of the smartphone 900 is not limited to the example of FIG. 10, and the smartphone 900 may include a plurality of antennas (e.g., an antenna for a wireless LAN and an antenna for a close proximity wireless communication scheme). In this case, the antenna switch 914 may be omitted from the configuration of the smartphone 900.

The bus 917 connects the processor 901, the memory 902, the storage 903, the external connection interface 904, the camera 906, the sensor 907, the microphone 908, the input device 909, the display device 910, the speaker 911, the wireless communication interface 913, and the auxiliary controller 919 to one another. The battery 918 supplies electric power to each of the blocks of the smartphone 900 illustrated in FIG. 10 via a power supply line partially indicated by dashed lines in the figure. The auxiliary controller 919 causes the required minimum functions of the smartphone 900 to operate, for example, in the sleep mode.
