<p>PURPOSE:To prolong the life of a paper battery by incorporating a vibrating generator which generates an electric power in an IC card by being vibrated from the external to give assistance to the paper battery. CONSTITUTION:An IC card incorporates a vibrating generator 5. Therefore, when a vibration is applied from outside the IC card, the vibrating generator 5 is actuated to generate an electric power. When an electric power accomplishes a constant voltage and a constant current, the electric power is supplied from the vibrating generator 5 to an electric circuit. When an electric power generated by the vibtating generator 5 is lower than a predetermined value, an electric power is supplied from a paper battery 4 to the electric circuit.</p> |
