Apparatus for measuring immunochromato test piece

An immunochromatographic test strip measuring apparatus comprising:

• a light illuminating unit, illuminating measurement light on an immunochromatographic test strip;
• a photodetecting unit, detecting light obtained from the immunochromatographic test strip by illumination of the measurement light;
• a test strip support, supporting the immunochromatographic test strip;
• a drive mechanism, moving the test strip support and the photodetecting unit in a relative manner in a sample flow direction of the immunochromatographic test strip;
• and
• a controller, controlling the drive mechanism;
• and
• wherein the controller makes the test strip support and the photodetecting unit move in a relative manner to detect light from a first position on the immunochromatographic test strip, then makes the test strip support and the photodetecting unit move in a relative manner to detect light from a second position at a downstream side of the first position, and acquires, based on output signals from the photodetecting unit, an elapsed time from a change of optical characteristic at the first position to a change of optical characteristic at the second position.

An immunochromatographic test strip measuring apparatus comprising:

• one or a plurality of light illuminating units, illuminating measurement light on an immunochromatographic test strip;
• a first photodetecting unit, detecting reflected light from the immunochromatographic test strip due to illumination of the measurement light on a first position on the immunochromatographic test strip;
• a second photodetecting unit, detecting reflected light from the immunochromatographic test strip due to illumination of the measurement light on a second position at a downstream side of the first position on the immunochromatographic test strip;
• and
• a controller, acquiring, based on output signals from the first and second photodetecting units, an elapsed time from a change of absorbance at the first position to a change of absorbance at the second position.
