Patent ID: 7234845

Claim:
A reflector for an electronic flash device, comprising: a pair of first reflective surfaces that are composed of portions of a cylindrical curved surface and face one another; and a second reflective surface that is contiguous with said pair of first reflective surfaces and in an inside portion of which a light source is housed, wherein contiguous portions where said pair of first reflective surfaces and said second reflective surface are contiguous are set closer to an opening of said pair of first reflective surfaces than a center portion of the housed light source; and wherein said second reflective surface comprises: a curved surface portion produced by setting the center portion of the light source as a center of a radius of curvature; a pair of inclined flat surface portions that are contiguous with respective ends of said curved surface portion and extend in tangential directions therefrom; and a pair of parallel flat surface portions that are substantially parallel with a center plane about which said pair of first reflective surfaces are symmetrical, said parallel flat surface portions intersecting said inclined flat surface portions.
