PROBLEM TO BE SOLVED: To provide a vibrating wave driving gear which drive-controls a vibrating wave motor as against a magnetic motor with high-precision, when the vibrating wave motor is operated in co-operation with the magnetic motor mutually. SOLUTION: A drive-controlling means for a vibrating wave motor 3 corrects a target value for the vibrating wave motor so that a second signal may have a specified phase difference from a first signal, on the basis of the difference between a BD signal generated at each specified operation performed by the drive of a magnetic motor and an encoder pulse signal of an encoder 4 which detects the rotation of the motor 3, and the vibrating wave motor is driven in synchronization with the magnetic motor. |
