摘要： A vibration wave motor includes a housing, a rotor, a bearing member, a vibrator serving as an actuator and having a support shaft and a driving element, and a leaf spring having a pressing protrusion. The vibrator is slidably disposed in an opening of the housing along a rotation axis direction of the rotor, and a support shaft of the vibrator is rotatable. The vibrator is held while being urged by the leaf spring and being in contact with the rotor. The vibrator is excited to generate supersonic vibration so that the rotor is rotated. Since the vibrator is movably supported by the housing in the rotation axis direction and the vibrator is urged by the leaf spring and is in contact with a friction contact surface of the rotor, the vibrator is evenly in contact with the rotor in a direction perpendicular to the friction contact surface so as to provide superior driving conditions of the vibration wave motor.
摘要翻译：振动波马达包括壳体，转子，轴承构件，用作致动器的振动器，并具有支撑轴和驱动元件，以及具有按压突起的板簧。振动器沿着转子的旋转轴线方向可滑动地设置在壳体的开口中，并且振动器的支撑轴可旋转。振动器被板簧推压并与转子接触时被保持。振动器被激发以产生超音速振动，使得转子旋转。由于振动器在旋转轴线方向上被壳体可移动地支撑，并且振动器被片簧推动并且与转子的摩擦接触表面接触，所以振动器在垂直于旋转轴线的方向上与转子均匀地接触摩擦接触表面，以提供振动波马达的卓越的驾驶条件。

摘要： A driving device in a lens barrel unit of a lens unit drives advancing/retreating of a lens frame holding a lens, and manual focusing. The lens frame is supported freely movably back and forth by an internal driving ring turned and driven when automatic focusing. The internal driving ring is supported by a distance ring so as to be turned and driven via an external driving ring supported turnably by a fixing frame. An operating ring is fixed on the perimeter of the distance ring, and manual focusing driving is performed by turning the operating ring. A transducer of an ultrasonic actuator is pressed against the end face of the distance ring via a driver, frictional contact force between the distance ring and the driver is adjusted by applying flexion standing wave vibration to the transducer, and the amount of turning operating force of the operating ring can be increased/decreased over a wide range.

摘要： In a digital camera system, a lens barrel adapted to a first camera body can be attached to a second camera body having a flange focal length which is shorter than that of the first camera body via an intermediate adapter, and the intermediate adapter is interposed to thereby set the flange focal length to be equal. Moreover, a compensating optical device is incorporated in the intermediate adapter to thereby match an optical distance from a mount surface to an image capture surface of the first camera body with an optical distance from a mount surface of the intermediate adapter to an image capture surface of the second camera body in a state in which the intermediate adapter is attached.
