ABSTRACT:
At least one exemplary embodiment is directed to an illuminating apparatus, configured to uniformly illuminate a surface of an object, and includes a light-guiding member configured to guide light emitted from a source to a surface to be illuminated, and a reflecting member disposed between the light-guiding member and the surface to be illuminated. The reflecting member includes a pair of reflection surfaces disposed so as to face each other in a long side direction of the surface to be illuminated, and reflects light emitted from the light-guiding member in directions having directional components parallel to a short side direction of the surface to be illuminated toward the surface to be illuminated.
