Abstract:
(EN) [Problem] To provide a drive device with which it is possible to reliably hold a moving object with a prescribed pressing force. [Solution] An imaging device (1) has a movable unit (100), a fixation unit (200) for holding the movable unit, and a control unit (201) for controlling the position of the movable unit relative to the fixation unit. At least a portion of the outer surface of the movable unit is spherical (SR), and the fixation unit has a plurality of vibration elements (11-13) brought into contact with the spherical surface of the movable unit by pressure and rotationally driving the movable unit, and a pressure-receiving unit (220a) for retaining the state of the plurality of vibration elements being held in contact with the movable unit by pressure. The movable unit is held between each of the plurality of vibration elements and the pressure-receiving unit, and the center of sphere ( C) of the spherical surface of the movable unit is located between a plane that passes through the plurality of vibration elements and the pressure-receiving unit.
(FR) [Problème] Fournir un dispositif d’entraînement avec lequel il est possible de maintenir de façon fiable un objet mobile avec une force de pression prescrite. [Solution] La présente invention concerne un dispositif d’imagerie (1) qui comporte une unité mobile (100), une unité de fixation (200) pour maintenir l’unité mobile, et une unité de commande (201) pour commander la position de l’unité mobile par rapport à l’unité de fixation. Au moins une partie de la surface externe de l’unité mobile est sphérique (SR), et l’unité de fixation comporte une pluralité d’éléments de vibration (11-13) mis en contact avec la surface sphérique de l’unité mobile par pression et entraînant en rotation l’unité mobile, et une unité de réception de pression (220a) pour conserver l’état de la pluralité d’éléments de vibration étant maintenus en contact avec l’unité mobile par pression. L’unité mobile est maintenue entre chacun de la pluralité d’éléments de vibration et de l’unité de réception de pression, et le centre de la sphère (C) de la surface sphérique de l’unité mobile est situé entre un plan qui traverse la pluralité d’éléments de vibration et l’unité de réception de pression.
(JA) 【課題】移動体を所定の加圧力で確実に保持することが可能な駆動装置を提供する。 【解決手段】撮像装置(1)は、可動部(100)と、可動部を保持する固定部(200)と、固定部に対する可動部の位置を制御する制御部(201)とを有し、可動部の外面の少なくとも一部は球面(SR)であり、固定部は、可動部の球面に加圧接触して可動部を回転駆動する複数の振動体(11~13)と、可動部に対する複数の振動体の加圧接触状態を保持する受圧部(220a)とを有し、可動部は、複数の振動体のそれぞれと受圧部とで挟持されており、可動部の前記球面の球心(C)は、複数の振動体を通る平面と受圧部との間に位置する。
