<p>A light scanner (LS) includes a fixed frame (FF), a frame axis portion (FA), a movable frame portion (FM), a mirror axis portion (MA), a mirror portion (MR), a holding portion (HD), and a piezoelectric element (PE). When the light scanner (LS) resonates, the frequency of a voltage applied to the piezoelectric element (PE) generates a vibration mode in which a phase of vibration at the time when the movable frame portion (FM) swings relative to the mirror axis portion (MA) and a phase of vibration at the time when the mirror portion (MR) swings relative to the mirror axis portion (MA) are made opposite to each other.</p> |
