PURPOSE:To reduce the size of the heat sink to miniaturize an equipment. CONSTITUTION:A heat sink 41 arranged in a radio transmission/reception part 38 which consumes much power at the time of data transmission is provided with a thermistor 42 which detects the temperature of this heat sink, and a CPU 31 instructs a modem part 37 to intermittently perform data transmission in the radio transmission/reception part 38 when detecting the temperature or ruse or the heat sink through the thermistor 42. As a result, not only the temperature rise in the equipment is suppressed but also the heat sink is reduced, and consequently, the equipment is miniaturized. |
