<p>PURPOSE:To provide a camera capable of reducing the influence of vibration caused by the driving of an actuator on other composing members. CONSTITUTION:A lens barrel has a fixed cylinder 1, a focus-lens-group-moving mechanism 25, a ultrasonic motor 10 which supplies a driving force to the moving mechanism 25, a shake detection means 20 which detects shake, and a hand shake correction mechanism 15 which corrects shake based on an amount of detected shake. In a stator hold member 4 for holding the stator 5 of the motor 10 and a sensor-fixing cylinder 16 for fixing the shake detection sensor 17 of the shake detection means 20, reinforcing parts 4a and 16a are formed so that their natural frequencies is not overlapped with the drive frequency band of the ultrasonic motor 10 and the frequency band of the vibration caused by the driving thereof.</p> |
