Abstract
The output of a synchronous detector is made precise by reducing the offset included in the outputs of detecting piezoelectric elements. This is carried out by applying one y-axis direction exciting force to one movable piece from one pair of driving piezoelectric elements and another y-axis direction exciting force to another movable piece from another pair of driving piezoelectric elements.
