Abstract

【課題】　磁石とコイルとを用いて可動部を駆動し、前記磁石に対向する磁気検知部を用いて可動部の移動位置を正確に検知できるようにする。 【解決手段】　可動部に磁石２１が設けられ、固定部にコイル２２と磁気検知部２３が設けられている。磁気検知部２３はコイル２２の側方で、且つ磁石２１と上下方向に重ならない位置に配置されている。磁石２１の対向面２１ａから発せられる磁束とコイル２２に流れる電流により、磁石２１がＹ方向へ移動させられる。磁気検知部２３はＸ－Ｙ平面内の磁界成分を検知でき、その検知出力により磁石２１の移動位置を検知できる。しかも磁気検知部２３はＸ－Ｚ面内の磁界の成分には反応しないため、コイル２２に流れる電流による電流磁界によって磁気検知部２３の検知出力が影響を受けることがない。
