<P>PROBLEM TO BE SOLVED: To fully reduce fluctuation in the speed of rotation of a drive transmission system without using an inertial body such a very large flywheel or being affected by individual differences of the inertial body or time of use. <P>SOLUTION: A photoreceptor drive 10 inclaudes a 3K differential planetary gear speed reducing mechanism, with a flywheel 50 connected to the output shaft thereof. The natural vibration frequency of the drive transmission system from an input shaft 17 to the output shaft is in a frequency band lower than the rotation frequency of a planetary gear. In the differential planetary gear speed reducing mechanism, an excitation frequency, which is the lowest frequency, is equal to the rotation frequency of the planetary gear, whereby all fluctuations in speed of rotation can be fully decreased by a flywheel of normal size. <P>COPYRIGHT: (C)2011,JPO&INPIT |
