Zusammenfassung: | A reflective member 17 is disposed on the optical path from the linear light source to the lens array 11. An ultraviolet light blocking filter 15 is provided closer to a light-receiving unit 12 than the reflective member 17. A color filter 18 is provided closer to the light-receiving unit 12 than the ultraviolet light blocking filter 15. A light-receiving surface 12A of the light-receiving unit 12 has a first region 121 opposed to the reflective member 17 without the ultraviolet light blocking filter 15 and the color filter 18 interposed therebetween, a second region 122 opposed to the reflective member 17 and the ultraviolet light blocking filter 15 without the color filter 18 interposed therebetween, and a third region 123 opposed to the reflective member 17, the ultraviolet light blocking filter 15, and the color filter 18. |
