Claim 3:
4. The cutting machine according to claim 2, wherein
the first lens includes an outer reflection surface configured to reflect, toward the first emission surface, light incident through the first incidence surface and passing through the first lens,
the outer reflection surface has (i) a convex shape, (ii) a first end that is an end of the outer reflection surface closest to the first emission surface and (iii) a second end that is another end of the outer reflection surface farthest from the first emission surface,
the outer reflection surface is farthest from the first center axis, in a plane perpendicular to the first center axis, at the first end of the outer reflection surface than at other planes perpendicular to the first center axis that intersect the outer reflection surface, and
distances between the outer reflection surface and the first center axis, in the first plane and the other planes perpendicular to the first center axis, decrease to the second end of the outer reflection surface.
