Abstract
A power supply unit inclding a batterythat stores electric power used for operations of various devices; a dynamo, a rotation support mechanism, and a rectifying sectionas charging means that converts natural energy into electric energy and supplies electric power of the electric energy to the batteryto be charged; a charging control sectionfor changing over between supply and stop of the electric power from the charging means to the storage means; and a charging control driving unitand a low-voltage charging function of an arithmetic processing partas charging changeover control means that controls the charging control sectionsuch that supply and stop of the electric power are repeated when the charging voltage for charging the batterywith electric power is not less than a predetermined value, and continues supply of the electric power when the charging voltage is less than the predetermined value.
