<P>PROBLEM TO BE SOLVED: To provide a driving force transmitting mechanism which can achieve miniaturization, lightweight and cost reduction, and can prevent deterioration of rotation accuracy when a configuration is used for exhibiting these functions. <P>SOLUTION: In the driving apparatus provided with a driving source 100 capable of controlling a speed using a frequency power generator; rotary signal generators 500, 501 formed of patterns opposite to magnetic poles 106A 301 provided on the rotor 106 of the driving source 100 are disposed for each of a plurality of circumferences provided around the rotary shaft 103A of the driving source 100, the cycles between the signal generators 500, 501 are made to be the same between all the circumferences, and the cycle of the signal generators is set at a multiple matched with the number of circumferences. <P>COPYRIGHT: (C)2008,JPO&INPIT |
