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