Abstract
(EN) In the present invention, an image sensor drive device (101) comprises a fixed-side member (FB), an image sensor holder (2) to which an image sensor (IS) is integrally provided, and a drive unit (DM) that causes the image sensor holder (2) to move relative to the fixed-side member (FB). The drive unit (DM) is configured including a shape memory alloy wire (SA) provided between the fixed-side member (FB) and a moveable-side member (MB) that includes the image sensor holder (2). The shape memory alloy wire (SA) includes first through eighth wires (SA1–SA8), and one end of each of the first through eighth wires (SA1–SA8) is fixed to the fixed-side member (FB) and the other end is fixed to the moveable-side member (MB).
(FR) Dans la présente invention, un dispositif d'entraînement de capteur d'image (101) comprend un élément côté fixe (FB), un support de capteur d'image (2) sur lequel un capteur d'image (IS) est formé d'un seul tenant, et une unité d'entraînement (DM) qui amène le support de capteur d'image (2) à se déplacer par rapport à l'élément côté fixe (FB). L'unité d'entraînement (DM) est conçue de façon à comprendre un fil d'alliage à mémoire de forme (SA) disposé entre l'élément côté fixe (FB) et un élément côté mobile (MB) qui comprend le support de capteur d'image (2). Le fil d'alliage à mémoire de forme (SA) comprend des premier à huitième fils (SA1–SA8), et une extrémité de chacun des premier à huitième fils (SA1–SA8) est fixée à l'élément côté fixe (FB) et l'autre extrémité est fixée à l'élément côté mobile (MB).
(JA) 撮像素子駆動装置(101)は、固定側部材(FB)と、撮像素子(IS)が一体的に設けられる撮像素子保持体(2)と、固定側部材(FB)に対して撮像素子保持体(2)を移動させる駆動部(DM)と、を備える。駆動部(DM)は、撮像素子保持体(2)を含む可動側部材(MB)と固定側部材(FB)との間に設けられた形状記憶合金ワイヤ(SA)を含んで構成される。形状記憶合金ワイヤ(SA)は、第1ワイヤ(SA1)乃至第8ワイヤ(SA8)を含み、第1ワイヤ(SA1)乃至第8ワイヤ(SA8)のそれぞれは、一端が固定側部材(FB)に固定され、他端が可動側部材(MB)に固定されている。
