PROBLEM TO BE SOLVED: To promote the downsizing and the reduction of operation labor by supplying load selectively with the power from the first power source part including a capacitor for power storage which is charged with the DC power converted from the power from the AC generator for generating electricity with a manual rotating mechanism, and the second power source part including a primary battery. SOLUTION: The three-phase AC voltage that a three-phase AC generator 11 generates by the rotation of the handle for rotation of a manual rotator 12 and the current are rectified with a group 420 of rectifying elements, and they are supplied to the electric double-layer capacitor 51 of a capacitor for power storage of the power source part to supply specified DC power so as to charge it. A switch 50 has a mobile contact 500 to be selectively connected to the contact 50A connected to the capacitor 51, the contact 50B connected to the primary battery 52 of the power source part, or a vacant contact 50C. A radio receiver constituent part 56 operates with the DC voltage and current of the capacitor 51 or the primary battery 52 as an operation power source, consequently it reduces the rotational torque of the rotor of the AC generator 11 for the charge of the capacitor 51, and dispenses with the secondary battery, and the downsizing and the reduction of operation labor can be materialized. |
