SMALL POWER GENERATING DEVICE AND MOBILE ELECTRONIC DEVICE

摘要

In a small power generator 1, a rotary dial 31 is disposed in the middle of the surface. By turning the rotary dial 31 with a finger, a rotor of an inner rotor type power generation unit 6, which is disposed inside the small power generator 1, is rotated by the rotational force through at least one intermediate gear. As a result, electric power is generated to charge a power supply for a portable electronic apparatus. The small power generator 1 includes an intermediate gear in order to transmit the rotational force of the rotary dial 31 to a rotating unit 3, and at least one of the shafts of the intermediate gear is provided between a plurality of core windings 67 circularly disposed in a stator core 66 of the power generation unit 6. Thus, in the small power generator 1, the planar size is reduced by providing the shaft of the intermediate gear inside the stator core of the inner rotor type power generator.
