    • There is provided a portable electronic device capable of being immediately operated without the use of a battery even when the battery reaches exhaustion. An electricity generating unit 131 is embedded in the portable electronic device. The electricity generating unit 131 has a mechanism to pull out a pull line 113 wound around a pulley 135 to wind up a spiral spring 133 and a mechanism to transfer torque occurring when the spiral spring 133 is released and to rotate the motor at high speed. An output voltage from the motor 142 is adjusted and smoothed by a constant voltage circuit and is directly supplied as power to power consuming components. The portable electronic device connecting two flips can wind up the spiral spring 133 by opening and closing the two flips.
    • 提供了即使在电池耗尽时也能立即使用电池而不使用电池的便携式电子设备。 发电单元131嵌入在便携式电子设备中。 发电单元131具有拉出缠绕在滑轮135上的拉线113以卷起螺旋弹簧133的机构,以及用于传递当螺旋弹簧133被释放时发生的扭矩并且使马达高速旋转的机构。 来自电动机142的输出电压由恒定电压电路调节和平滑,并且直接作为功率供应给功率消耗部件。 连接两个翻转件的便携式电子设备可以通过打开和关闭两个翻转来卷起螺旋弹簧133。
