The apparatus includes a rod-shaped light conductor, a light emitting element, a concave reflection mirror, and a diffusing-and-reflecting member that has a diffusing-and-reflecting plane disposed to face a reflecting portion of the light conductor along the longitudinal direction. The diffusing-and-reflecting member has a facing portion facing the light emitting element. The facing portion is provided at the end of the diffusing-and-reflecting plane of the diffusing-and-reflecting member in the vicinity of the light emitting element. Light from the light emitting element and/or the concave reflection mirror is incident on the light emitting element facing portion. That light is reflected toward the end face of the light conductor in the vicinity of the light emitting element, and introduced into the light conductor. | 12-04-2014 |
