摘要

PROBLEM TO BE SOLVED: To provide a driving control method for oscillatory wave motor, capable of attaining longer life of an oscillatory wave motor and being driven with fixed characteristics. ;SOLUTION: This driving control for oscillatory wave motor, which drives a body to be driven such as a photosensitive drum using the oscillatory wave motor as its driving source, drives the oscillatory wave motor at a rotational speed capable of recovering the friction driving part of the oscillatory wave motor after the completion of the driving operation of the body to be driven, if the rotational speed of the oscillatory wave motor is lower than a prescribed one.;COPYRIGHT: (C)2000,JPO
