<P>PROBLEM TO BE SOLVED: To obtain a motor apparatus capable of transmitting the rotation of an output shaft to a driven body accurately and a photoreceptor drum unit capable of rotating the photoreceptor drum accurately by the motor apparatus. <P>SOLUTION: An outer rotor motor 10 includes: the output shaft 26, which is formed in a cylindrical shape having an opening 56A at the end of the photoreceptor drum 70 side in the axial direction and rotated to a stator 12 by the rotation of a rotor 24; a chuck structure part 62, which is provided at the rear part 56C opposite to the opening 56A on the output shaft 26 to fix a connecting shaft 82 inserted coaxially into the output shaft 26; and a code wheel 36, which is provided at the outside circumferential side of the output shaft 26 so as to be rotated coaxially and integrally to output a signal according to the rotation state of the output shaft 26 to a rotation sensor 40. <P>COPYRIGHT: (C)2009,JPO&INPIT |
