Abstract
(EN)
The present invention provides a driving device that can be reduced in overall size. A mirror (2) is rotatably supported by a rotary frame (3) via inner torsion bars (20), and the rotary frame (3) is rotatably supported by a base part (4) via outer torsion bars (30). By providing magnetic elements (5A, 5B) on the rotary frame (3), the mirror (2) and ends (74, 75) of yoke parts (7A, 7B) are inhibited from interfering with each other, and, by disposing the magnetic elements (5A, 5B) and the ends (74, 75) close to each other, the size of the overall device can be reduced.

L'invention concerne un dispositif d'entraînement qui peut avoir une taille hors-tout réduite. Un miroir (2) est supporté de manière rotative par un cadre rotatif (3) par l'intermédiaire de barres de torsion internes (20), et le cadre rotatif (3) est supporté de manière rotative par une partie de base (4) par l'intermédiaire de barres de torsion externes (30). En disposant des éléments magnétiques (5A, 5B) sur le cadre rotatif (3), le miroir (2) et les extrémités (74, 75) des parties de culasse (7A, 7B) ne peuvent pas interférer les uns avec les autres, et le fait de disposer les éléments magnétiques (5A, 5B) et les extrémités (74, 75) proches les uns des autres permet de réduire la taille du dispositif global.

装置全体を小型化することができる駆動装置を提供する。ミラー(2)が、内側トーションバー(20)を介して回動フレーム(3)によって回動可能に支持され、回動フレーム(3)が、外側トーションバー(30)を介してベース部(4)によって回動可能に支持される。磁気素子(5A、5B)が回動フレーム(3)に設けられていることで、ミラー(2)とヨーク部(7A、7B)の端部(74、75)とが干渉しにくく、磁気素子(5A、5B)と端部(74、75)とを近接配置することによって装置全体を小型化することができる。
