Abstract
A first sensor and a second sensor provided on both ends of a moving portion connected to a fixed portion via an elastic body detect displacements of the moving portion that is in an oscillating movement. An angle calculating unit calculates a displacement angle of the moving portion based on the displacements detected by the first sensor and the second sensor and a distance between the first sensor and the second sensor.
