Abstract:
(EN) The present invention ensures the smooth rotation of a rotary drive body by means of a simple structure without compromising the characteristics of an ultrasonic motor. The present invention is provided with: an ultrasonic motor which has a rotor and a stator; a rotary drive body which is rotated around an axis by the driving force of the ultrasonic motor so as to move an optical element in the axial direction; a bearing which is capable of rotating around the axis; and a compression spring which imparts an axially biasing force to the ultrasonic motor, the rotary drive body, and the bearing, wherein the compression spring biases the rotor and the stator in the contact direction, and biases the rotary drive body and the bearing in the contact direction.
(FR) La présente invention garantit la rotation uniforme d'un corps d'entraînement rotatif au moyen d'une structure simple sans compromettre les caractéristiques d'un moteur ultrasonique. La présente invention comprend : un moteur ultrasonique qui a un rotor et un stator ; un corps d'entraînement rotatif qui tourne autour d'un axe grâce à la force d'entraînement du moteur ultrasonique de façon à déplacer un élément optique dans la direction axiale ; un palier qui est apte à tourner autour de l'axe ; et un ressort de compression qui confère une force de sollicitation axiale au moteur ultrasonique, au corps d'entraînement rotatif, et au palier, le ressort de compression sollicitant le rotor et le stator dans la direction de contact, et sollicitant le corps d'entraînement rotatif et le palier dans la direction de contact.
(JA) 超音波モーターの特性を低下させることなく回転駆動体の円滑な回転状態を簡素な構造によって確保する。ローターとステーターを有する超音波モーターと、超音波モーターの駆動力によって軸回り方向へ回転され光学素子を軸方向へ移動させる回転駆動体と、軸回り方向へ回転可能なベアリングと、超音波モーターと回転駆動体とベアリングに軸方向への付勢力を付与する加圧バネとを備え、加圧バネによってローターとステーターが接する方向へ付勢されると共に回転駆動体とベアリングが接する方向へ付勢された。
