PURPOSE: To enhance measuring accuracy and to measure the degrees of color development of a plurality of small pieces by providing a frame-like part pressing ground paper along the outside of a plurality of the small pieces containing a reagent to a clamper.
CONSTITUTION: When urine data is analyzed by irradiating an urine data analyser 2 with light, a press part 24 is provided to a clamper 12 grasping test paper 8 and constituted of a frame-like part 25 pressing ground paper 80 along the outside of a plurality of small pieces 81 containing reagents and shield parts 26 pressing the ground paper 80 between the respective small pieces. In analyzing urine data, the frame-like part 25 of the clamper 12 presses the parts along the outside parts of the small pieces 81... of the test paper 8 and the shield parts 26 press the spaces between the respective small pieces 81.... When the respective small pieces 81 are simultaneously analyzed, a plurality of light emitting elements are prepared and the respective pieces 81 are irradiated with light having wavelengths optimum to components to be detected through the spaces surrounded by the respective shield parts 26 and the ratios of the specific components in urine can be known on the basis of the quantities of reflected lights.
