Abstract
(EN)
This light reflection device (20) is provided with a reflection member (42) having a planar reflection surface. The reflection surface reflects incident light. The reflection member (42) performs revolution and rotation simultaneously. The direction of revolution and the direction of rotation of the reflection member are the same. The revolution angular velocity of the reflection member (42) is equal to twice the rotation angular velocity thereof.

Dispositif de réflexion de lumière (20) pourvu d'un élément de réflexion (42) ayant une surface de réflexion plane. La surface de réflexion réfléchit la lumière incidente. L'élément de réflexion (42) effectue simultanément une révolution et une rotation. Les direction de révolution et de rotation de l'élément de réflexion sont les mêmes. La vitesse angulaire de révolution de l'élément de réflexion (42) est égale à deux fois la vitesse angulaire de rotation de celui-ci.
(JA)
本発明における光反射装置(20)は、平面状の反射面を有する反射部材(42)を備える。反射面は、入射光を反射させる。反射部材(42)は、公転及び自転を同時に行う。反射部材の公転の方向と自転の方向が同一である。反射部材(42)の公転角速度が自転角速度の2倍に等しい。
