Abstract:
(EN) In the actuator pertaining to the present invention, a support part (20) for supporting a driven part (10), and outer-axis drive parts (Dsa, Dsb) for causing the support part (20) to rotate are provided separately and independently. Through this configuration, a rotary portion can be reduced in size and weight, rotational moment is reduced, and it is possible to set the resonance frequency of the support part (20) to a high value while making it possible to obtain adequate drive force about an outside second axis (AX2); e.g., high-performance drive operation such as operation by raster scanning is possible.
(FR) Dans l'actionneur de la présente invention, une partie de support (20) destinée à soutenir une partie entraînée (10), et des parties d'entraînement d'axe externe (Dsa, Dsb) destinées à amener la partie de support (20) à tourner sont disposées séparément et indépendamment. Grâce à cette configuration, une partie rotative peut être réduite en taille et en poids, le moment de rotation est réduit, et il est possible de régler la fréquence de résonance de la partie de support (20) à une valeur élevée tout en permettant d'obtenir une force d'entraînement adéquate autour d'un second axe externe (AX2) ; par exemple, une opération d'entraînement à haute performance telle qu'une opération par balayage de trame est possible.
(JA) 本発明に係るアクチュエータは、被駆動部(10)を支持する支持部(20)と、支持部(20)を回転させる外軸駆動部(DSa,DSb)とを分離独立して設けている。これにより、回転部分の小型化、軽量化を図り、回転モーメントを低減させて、外側の第2軸(AX2)の周りについて十分な駆動力を得ることを可能としつつ、支持部(20)の共振周波数を高く設定することが可能になり、例えば、ラスタースキャンによる動作といった高性能な駆動動作が可能になっている。
