The device includes a piezoelectric vibrator and a modulation means driven by the vibration of the piezoelectric vibrator, and the modulation means is composed of a movable slit plate having a light-transmitting part and a light-shielding part. A locking portion consisting of a part of the movable slit plate is integrally formed, and this locking portion is fitted to one end of the piezoelectric vibrator, thereby attaching and fixing the movable slit plate to one end of the piezoelectric vibrator.
