Patent number: 10481391Abstract: Actuators (140), which are a pair of members, are disposed one on either side of a movable frame (120) in the X-axis direction, and oscillate the movable frame (120) about the X axis in relation to a fixed frame (110) by deformation caused by stretching and contracting of piezoelectric elements. Actuators (150), which are a pair of members, are disposed one on either side of a mirror (130) in the Y-axis direction, and oscillate the mirror (130) about the Y axis in relation to the movable frame (120) by deformation caused by stretching and contracting of the piezoelectric elements. The length of each actuator (140) extending in the Y-axis direction is longer than a distance between an inner side of the fixed frame (110) to which the actuator (140) is connected and the middle point of an outer side of the movable frame (120) in the Y-axis direction.Type: GrantFiled: June 6, 2016Date of Patent: November 19, 2019Assignee: DAI-ICHI SEIKO CO., LTD.Inventors: Kenji Ogata, Shinya Sakamoto, Yoshifumi Ikeda, Shogo Kurogi, Kazuhiro Okada, Satoshi Era

Patent number: 10473917Abstract: A mirror with a reflective layer formed thereon is supported within a frame-shaped support by two U-shaped arms. A plate-like arm connects fixation points (Q1, Q2), and a plate-like arm connects fixation points (Q3, Q4). A pair of piezoelectric elements (E11, E12) disposed along a longitudinal axis (L1) on an upper surface of an outside bridge of the arm, and a single piezoelectric element (E20) disposed along the longitudinal axis (L2) on the upper surface of an inside bridge. Similarly, a pair of piezoelectric elements (E31, E32) disposed on an upper surface of an outside bridge of the arm, and a single piezoelectric element (E40) disposed on the upper surface of an inside bridge.
