PROBLEM TO BE SOLVED: To realize an energy saving function to conserve power to the absolute minimum according to an energy saving release factor by outputting a power source control signal to a power supply control means and providing an energy saving control means to inform the main control means of the detected energy saving release factor. SOLUTION: On/off control of supply of a main power source is performed by every unit according to the power source control signal from an energy saving control part 2 by a power supply control part 4. And it is detected whether an incoming call is a telephone call (TEL mode) or a G4 incoming call by a G4 incoming mode detecting part 5a and the energy saving control part 2 is also informed of its detection result as an energy saving release trigger signal. When transition to an energy saving state is instructed by an energy saving control signal, an electric apparatus and a communication terminal are transited to the energy saving mode by the energy saving control part 2. When the energy saving mode is released after that, a main control part 1 is informed of its release factor by an energy saving release factor signal by the energy saving control part 2. |
