<P>PROBLEM TO BE SOLVED: To provide a motor drive control apparatus capable of easily ejecting a rotor from the body. <P>SOLUTION: In the motor drive control apparatus provided with an encoder 7 fixed to a driving shaft 6 of the rotor (photoreceptor 2) to be rotated by a motor 3 and a translucent sensor for detecting a slit of the encoder 7 and is allowed to control the drive of the motor 3 so as to reduce the cycle variation of the rotor on the basis of an output from the translucent sensor; a light projection part 11 and a light receiving part 12 in the translucent sensor are arranged separately and independently through the encoder 7. <P>COPYRIGHT: (C)2007,JPO&INPIT |
