Abstract
A light source device includes: a first light source; first cylindrical lenses; a light beam merging unit disposed to narrow a width in a first direction of a light flux emitted from the first light source by allowing partial light from the first cylindrical lenses to pass through the light beam merging unit and reflecting remaining light; and a condenser lens configured to condense light emitted through the light beam merging unit. The first light source includes light emitting elements disposed side by side in the first direction in a first column, and collimator lens parts disposed corresponding to the light emitting elements in the first column. Each of the light emitting elements in the first column includes a first emitter that emits first light, and a second emitter that emits second light. Each of the collimator lens parts allows transmission of the first light and the second light.
