Abstract: A micro oscillating device includes a frame, an oscillating part including a first drive electrode for application of a reference electric potential, and a connecting part for connecting the frame and the oscillating part to each other, where the connecting part defines an axis of an oscillating motion of the oscillating part. A second drive electrode is fixed to the frame to cooperate with the first drive electrode for generation of a driving force for the oscillating movement. The first drive electrode includes a first end extension and a second end extension separated from each other and extending in a direction crossing the axis. The second drive electrode is within a separation distance between the first and the second end extensions.

Abstract: 支持梁の連結部位を回転支持部として構成することにより、可動体を各切換位置に安定的に保持できる構成とし、信頼性を高めるようにする。可動体4を、基板2、各固定部6、回転支持部8、支持梁7によりY軸方向に変位可能に支持し、可動体4を第1,第2の切換位置の間で変位させる。また、回転支持部8は、放射状に配置した腕部9,10,11により支持梁7を回転可能に支持し、可動体4が変位するときには、端部7Aが大きく屈曲しなくても、支持梁7が回転できるようにする。これにより、第1,第2の切換位置の間で可動体4の位置エネルギの障壁ΔEを大きく設定でき、電極12〜15への給電を停止した状態でも、可動体4を各切換位置に安定的に保持することができる。また、可動体4がX軸方向に位置ずれするのを腕部10により防止することができる。
