A first communication interface (11) is connected to a LAN (3). When a link of the first communication interface (11) is not detected or when data transfer is not detected, a processor (12) controls a power supply control unit (15) and stops power supply to a RAM (13), a flash memory (14) and to a second communication interface (16). Then, the processor (12) enters a power saving mode. Thus, power consumption can significantly be reduced. |
