PROBLEM TO BE SOLVED: To realize a portable equipment with a generator of a small size, a thin type and a high efficiency without accelerating gear wheel train mechanism. SOLUTION: An unbalance wheel 2 having a multipolar permanent magnet 1 at a periphery, and a coil 3 near the magnet 1 are provided. In this case, an AC current generated in the coil 3 by the rotation of the wheel 2 is rectified by a rectifier 4 having a diode. Rectified charge is stored in a capacitor 5 to operate a timepiece 6. |
