Abstract:
An electronic apparatus, which is portable, comprising:power generating means for generating power by converting a first energy to an electrical energy;power source means for accumulating the electrical energy generated by the power generating means;means to be driven by electrical energy supplied from the power source means;power-generation detection means for detecting whether the power generating means is generating power;voltage detection means for detecting whether one of a power-generation voltage at the power generating means and an accumulated voltage at the power source means exceeds a predetermined reference voltage;limiter means for limiting the voltage of the electrical energy supplied to the power source means to a predetermined reference voltage, according to a detection result of the voltage detection means;operation-mode control means for switching the operation mode of the means to be driven between a normal operation mode and a power-saving operation mode, according to a detection result of the power-generation detection means; andlimiter control means for disabling the limiter means when the means to be driven is switched to the power-saving mode.
