Title (EN) VIBRATION DEVICE
(FR) DISPOSITIF DE VIBRATION
(JA) 振動装置
Abstract:
(EN) Provided is a vibration device capable of reliably removing a drop of water that is in the field of view of an imaging device and attached to a surface of a light transmission body disposed on a subject side of an imaging element. This vibration device 1 is provided with: a light transmission body 2 disposed on a subject side of an imaging element 9; a cylindrical body 3 having a first end portion 3a, a second end portion 3b on the opposite side as the first end portion 3a, and an outer surface 3d and an inner surface 3e connecting the first end portion 3a and the second end portion 3b, the cylindrical body 3 being connected to the light transmission body 2 so as to hold the light transmission body 2 on the side of the first end portion 3a; and a piezoelectric element 4 disposed along the circumferential direction of the cylindrical body 3 so as to torsionally vibrate the cylindrical body 3.
(FR) L'invention concerne un dispositif de vibration susceptible d'éliminer de manière fiable une goutte d'eau qui se trouve dans le champ de vision d'un dispositif d'imagerie et fixé à une surface d'un corps de transmission de lumière disposé sur un côté sujet d'un élément d'imagerie. Le dispositif de vibration (1) selon l'invention comprend : un corps de transmission de lumière (2) disposé sur un côté sujet d'un élément d'imagerie (9) ; un corps cylindrique (3) ayant une première partie d'extrémité (3a), une seconde partie d'extrémité (3b) sur le côté opposé à la première partie d'extrémité (3a) et une surface externe (3d) et une surface interne (3e) reliant la première partie d'extrémité (3a) et la seconde partie d'extrémité (3b), le corps cylindrique (3) étant relié au corps de transmission de lumière (2) de façon à maintenir le corps de transmission de lumière (2) sur le côté de la première partie d'extrémité (3a) ; et un élément piézoélectrique (4) disposé le long de la direction circonférentielle du corps cylindrique (3) de façon à faire vibrer en torsion le corps cylindrique (3).
(JA) 撮像素子の被写体側に配置された透光体表面に付着した、イメージングデバイスの視野内における水滴などを確実に除去することができる、振動装置を提供する。 振動装置1は、撮像素子9の被写体側に配置される透光体2と、第1の端部3aと、第1の端部3aとは反対側の第2の端部3bと、第1の端部3a及び第2の端部3bを接続している外側面3d及び内側面3eとを有し、第1の端部3a側において、透光体2を保持するように、透光体2に連結されている筒状体3と、筒状体3をねじり振動させるように、筒状体3の周方向に沿って配置されている圧電素子4とを備える。
