Abstract
The present invention comprises a discharge lamp (,) for emitting light; a cold mirror (,), having an opening portion, for reflecting the light emitted from the discharge lamp; a reflecting mirror (,), located on the opening portion side of the cold mirror, for reflecting the light reflected by the cold mirror; a light-shielding drum (,) having a light emission port (,) for emitting the light reflected by the reflecting mirror; a stepping motor,for driving the reflecting mirror and the light-shielding drum to rotate about an optical axis of the discharge lamp; rotational angle detecting means (,) for detecting a rotational angle of the reflecting mirror and the light-shielding drum; and control means (,) for controlling, according to the rotational angle detected by the rotational angle detecting means, the rotational driving of the reflecting mirror and the light-shielding drum (,) caused by the stepping motor,wherein any of a plurality of irradiation ports is selectively irradiated through the light emission port of the light-shielding drum with the light reflected by the reflecting mirror.
