Abstract: A camera having a camera system which is capable of reducing the influence that vibration generated in conjunction with driving of an actuator has on other component members of the camera system. The camera includes a lens barrel having a fixed cylinder, a focusing lens group moving mechanism, an actuator, such as an ultrasonic motor, to supply a driving force to the lens group moving mechanism, a vibration detection device to detect vibration, and a camera vibration compensation mechanism to compensate for the detected vibration. The camera system includes a component member having multiple reinforcing sections and a characteristic frequency which does not overlap with a drive frequency band of the ultrasonic motor or with the vibration frequency band of the vibration generated in conjunction with the driving of the ultrasonic motor. The component member may be a stator retaining member which supports a stator of the ultrasonic motor, or a sensor fixed cylinder which secures the vibration detection device.

Abstract: A driving device for an ultrasonic motor has a limit detecting circuit for detecting that the drive voltage for the ultrasonic motor has reached a limit, and, in response, a drive voltage limiting circuit controls the drive voltage so as not to go beyond the limit value. Such control is conducted on the voltage or frequency of a signal for driving the ultrasonic motor. In another aspect of the invention, a drive state detecting circuit detects the drive state of the ultrasonic motor, and a drive frequency (or voltage) setting circuit controls the frequency (or voltage) of a signal for driving the ultrasonic motor so as to attain the maximum efficiency in the motor, based on the output of the drive state detecting circuit.
