The vibrator has first spring portions (9, 10) connected to the reflective mirror portion, and a plurality of second spring portions (12, 13, 15, 16) which are connected to the first spring portions, branch off with a distance wider than the width of the first spring portions and are connected to a fixing frame portion (7) of the vibrator. Torsional vibration is produced in the first spring portions (9, 10), and bending vibration and torsional vibration are produced in the second spring portions (12, 13, 15, 16).</p> |
