Abstract
(EN) An optical unit (100) is provided with: a movable body (120) that has an optical element; a fixed body (110) that surrounds the movable body (120); and an oscillation mechanism (140) for supporting the movable body (120) so as to be oscillatable with respect to the fixed body (110). The oscillation mechanism (140) has: a spherical body (150) that comes into contact with either of the movable body (120) and the fixed body (110); an elastic body (160) that pushes the spherical body (150) toward either of the movable body (120) and the fixed body (110); and a holding part (170) that holds the spherical body (150) so as to be rollable with respect to either of the movable body (120) and the fixed body (110).
(FR) L'invention concerne une unité optique (100) pourvue : d'un corps mobile (120) comprenant un élément optique ; d'un corps fixe (110) qui entoure le corps mobile (120) ; et d'un mécanisme d'oscillation (140) permettant de soutenir le corps mobile (120) de façon à pouvoir osciller par rapport au corps fixe (110). Le mécanisme d'oscillation (140) comprend : un corps sphérique (150) qui vient en contact soit avec le corps mobile (120) soit avec le corps fixe (110) ; un corps élastique (160) qui pousse le corps sphérique (150) soit vers le corps mobile (120) soit vers le corps fixe (110) ; et une partie maintien (170) qui maintient le corps sphérique (150) de façon à être enroulable par rapport soit au corps mobile (120) soit au corps fixe (110).
(JA) 光学ユニット(100)は、光学素子を有する可動体(120)と、前記可動体(120)の周囲を囲む固定体(110)と、前記固定体(110)に対して前記可動体(120)を揺動可能に支持する揺動機構(140)とを備え、前記揺動機構(140)は、前記可動体(120)および前記固定体(110)のうちの一方と接触する球体(150)と、前記可動体(120)および前記固定体(110)のうちの一方に向かって前記球体(150)を押す弾性体(160)と、前記可動体(120)および前記固定体(110)のうちの一方に対して前記球体(150)を転がり可能に保持する保持部(170)とを有する。
