A scanning mechanism 6 moves an optical head 5 relative to a mount plate 2 in a scan direction, and light emitting diodes 3 A, 3 B mounted on the optical head 5 emit their respective beams of measurement light along the scan direction and onto two color regions TP 3 , TP 3 , respectively, of an immunochromatographic test strip mounted on the mount plate 2 . Photodiodes 4 A, 4 B mounted on the optical head 5 receive respective beams of reflected light from the two color regions TP 3 , TP 3 perpendicularly to colored lines on the immunochromatographic test strip, thereby implementing simultaneous measurement of color intensities of the colored lines formed in the two color regions TP 3 , TP 3 of the immunochromatographic test strip.
