Abstract
The control part controls a timing of changing the light emission intensity of the first light source and a timing of changing the light emission intensity of the second light source such that a first light-shielding portion is formed in a part of the first irradiation pattern, a second light-shielding portion is formed in a part of the second irradiation pattern so as to overlap with the first light-shielding portion, and a range of the first light-shielding portion and a range of the second light-shielding portion are deviated from each other.
