PROBLEM TO BE SOLVED: To generate electric energy without providing a battery or the like by providing a generator formed in a thickness or less of a card base material to generate the electric energy according to change of a motion generated at the card. SOLUTION: A generator unit 13 is formed in a thickness or less of a card base material. A partial area of the material is punched, and the unit 13 is disposed at the area. For example, when an owner walks, a change of motion occurs at an IC card, and a rotary weight 13a is rotated at its center as a fulcrum. This rotation is accelerated by a gear train 13b, and transmitted to a rotor 13c. When the rotor 13c is rotated, a magnetic flux crossing a driving coil 13e is changed through a stator 13d, an AC voltage is generated in the coil 13e by means of electromagnetic induction. This voltage is supplied to an IC module via a rectifying, charging and constant-voltage circuits. The module is driven with the voltage as power. |
