An image display device of the present invention includes two lamps A and B as light sources. A mirror is pivotally moved to supply light from the lamp A, B to an optical system. In the case where the lamp A is used, the mirror is temporarily driven in the direction of lamp B before the lamp A is activated. Thereafter, the mirror is returned to the position where the lamp A is used, and is pressed against a restraining member. Thereby, the mirror is positioned at a proper angle with respect to the light from the lamp A when the lamp A is activated.
