The first light source has a first row of a plurality of light emitting elements disposed side by side in the first direction, and a plurality of collimator lens parts disposed to respectively correspond to the first row of the plurality of light emitting elements. Each of the first row of the plurality of light emitting elements has a first emitter that emits first light and a second emitter that emits second light, and each of the plurality of collimator lens parts transmits the first light and second light. The plurality of first cylindrical lenses are disposed to respectively correspond to the first row of the plurality of light emitting elements, and collimate the first light and the second light emitted from the first light source.
