<P>PROBLEM TO BE SOLVED: To provide a drive unit capable of resolving a failure of a drive transmission mechanism, which transmits rotational power of a motor to an operation part, by itself. <P>SOLUTION: An arithmetic and control part 11 includes vibration means 16 for resolving a failure which occurs at a drive transmission mechanism 4 by giving impact on the drive transmission mechanism 4. The vibration means 16 is configured to perform vibration operation when the number counted by an encoder 8 does not get into a convergence state within a predetermined time since drive of a motor 6 has been started. <P>COPYRIGHT: (C)2013,JPO&INPIT |
