Abstract:
A measuring device for an immunochromatography test piece comprising an irradiation optical system for irradiating measurement light onto said immunochromatography test piece; and a detection optical system for detecting light from said immunochromatography test piece due to said measurement light;wherein said detection optical system comprises a cylindrical lens and an imaging element; wherein said cylindrical lens is disposed in such a manner that the direction of a generating line thereof intersects with the direction of travel of antigens or antibodies in said immunochromatography test piece, and creates an image on said imaging element of a pattern formed on said immunochromatography test piece in a direction intersecting with the direction of travel of said antigens or antibodies, due to the irradiation of said measurement light from said irradiation optical system; and wherein a member having a slit formed to extend in the direction of the generating line of said cylindrical lens is further provided between said immunochromatography test piece and said cylindrical lens.
