Abstract
A measuring unit measures an amount of a detected phase difference from an output of a vibration detection signal from a first detection electrode until an output of a vibration detection signal from a second detection electrode. A setting unit sets a second driving phase difference amount based on the detected phase difference amount measured by the measuring unit when the setting unit sets a first driving phase difference amount set in advance. A first voltage applied by a drive unit to the first drive electrode and the second drive electrode when the setting unit sets the first driving phase difference amount, is lower than a second voltage applied by the drive unit to the first drive electrode and the second drive electrode when the setting unit sets the second driving phase difference amount.
