A light emitting device includes a plurality of light emitting elements aligned along a reference line, a plurality of lenses that collects light emitted from the plurality of light emitting elements, and a drive circuit that allows either a first light emitting element or a second light emitting element to emit light. The plurality of lenses includes a first lens and a second lens that is disposed on an opposite side of the first lens with the reference line interposed therebetween, and a distance between the center of the first lens and the reference line is the same as a distance between the center of the second lens and the reference line. The plurality of light emitting elements includes the first light emitting element and the second light emitting element that is disposed on an opposite side of the first light emitting element with the reference line interposed therebetween. A distance between the first light emitting element and the reference line is the same as a distance between the second light emitting element and the reference line.
