Abstract: An input device includes: a switch to be switched by being pressed; a plurality of light sources including a first light source and a second light source; and a light guide that guides light emitted from each of the plurality of light sources. The light guide includes: an emission part that emits the light; a first light guide leg that is coupled to the emission part and guides first light to the emission part; and a second light guide leg that is coupled to the emission part and guides second light to the emission part. The emission part includes a first design that illuminates by reflecting the first light, and a second design that illuminates by reflecting the second light. The first light guide leg includes a first reflection surface that reflects the first light. The second light guide leg includes a second reflection surface that reflects the second light.

Abstract: A light guide plate includes: an annular part formed in an annular shape along an element array of multiple light emitting elements; and an annular inner part formed on an annular inside of the annular part continuously with the annular part. The annular part includes: an element array-facing part which is a part facing the element array and which has an incident surface to allow light emitted from the light emitting elements to enter; and a first reflecting part which is a part located closer to the annular inner part than the element array-facing part, and which has a reflecting surface for reflecting the light entering from the incident surface toward the annular inner part. The first reflecting part includes a first light scattering region having a light scattering treatment applied thereto.

Abstract: An input operation device according to the present disclosure includes first to third light-emitting sections, a first light guide body, and a second light guide body. A lower end of the first light guide body faces the first light-emitting section and the second light-emitting section. The first mark emits light on the first light guide body when light is incident on the first light guide body from the first light-emitting section, and the second mark emits light on the first light guide body when light is incident on the first light guide body from the second light-emitting section. The upper surface section of the second light guide body emits light when light is incident on the second light guide body from the third light-emitting section. At least one of the first light-emitting section, the second light-emitting section, and the third light-emitting section can change light emission luminance.

Abstract: An illumination device has plural LED light sources, a reflection plate that has plural openings facing the respective LED light sources, and plural lenses that faces the respective openings and that guides light emitted from the plural openings in a direction vertical to the openings. The reflection plate is placed between the plural LED light sources and the plural lenses, and converges the light emitted from the plural LED light sources.

Abstract: An illumination apparatus includes a light-emitting element, a first lens, and a second lens. A first incident surface of the first lens faces the light-emitting element, and guides a light beam from the light-emitting element to a radiation port. A second incident surface of the first lens guides a light beam not passing through the first incident surface to a direction toward the outer periphery of the first lens. A first reflection surface of the first lens reflects a light beam from the second incident surface to guide the light beam to the radiation port.
