Abstract
Actuators (), which are a pair of members, are disposed one on either side of a movable frame () in the X-axis direction, and oscillate the movable frame () about the X axis in relation to a fixed frame () by deformation caused by stretching and contracting of piezoelectric elements. Actuators (), which are a pair of members, are disposed one on either side of a mirror () in the Y-axis direction, and oscillate the mirror () about the Y axis in relation to the movable frame () by deformation caused by stretching and contracting of the piezoelectric elements. The length of each actuator () extending in the Y-axis direction is longer than a distance between an inner side of the fixed frame () to which the actuator () is connected and the middle point of an outer side of the movable frame () in the Y-axis direction.
