<P>PROBLEM TO BE SOLVED: To realize a power generator in which the use operation is efficiently converted into electric energy. <P>SOLUTION: The power generator includes: a writing pressure power generating part 30 that generates an electromotive force in response to the writing pressure applied to a pen tip 201 of a stylus pen 10; a thermal power generating part 40 that generates the electromotive force obtained by thermoelectrically converting the body temperature of a user gripping the stylus pen 10; an optical power generating part 50 that generates the photoelectrically converted electromotive force according to the amount of light received under the environment using the stylus pen 10; and a vibration power generating part 60 that generates the electromotive force according to vibration generated when the stylus pen 10 is used. Accordingly, not only mechanical vibration can be converted simply into the electric energy, but also the use operation can be converted efficiently into the electric energy unlike conventional generators. <P>COPYRIGHT: (C)2010,JPO&INPIT |
