Abstract
A wireless controller is provided with at least two power supplies. The internal components of the controller are classified into at least two groups in accordance with the degrees of functional importance or the power consumptions of the components. The power supplies separately supply electric power to the respective groups of the components. Thus, the power supply to components with high degrees of functional importance or low power consumptions is ensured for a long time.
