<P>PROBLEM TO BE SOLVED: To reduce the imbalance of the mass distribution of a driving device by mounting drive motors on an apparatus body separately from one another. <P>SOLUTION: In a driving unit 100, a first drive motor 110 is disposed in a first area A, a second drive motor 120 is disposed in a second area B, a third drive motor 130 is disposed in a third area C, and a fourth drive motor 140 is disposed in a fourth area D. Since the drive motors 110 to 140 are mounted on the apparatus body 102 separately from one another in such a manner, imbalance of the mass distribution of the driving unit 100 is reduced. <P>COPYRIGHT: (C)2011,JPO&INPIT |
