PURPOSE:To display a visual comparative decision result speedily through easy operation by converting the comparative decision result into an electric signal by a wheel for operation which has a color sample for comparison on its top surface and an corresponding uneven code part on its reverse surface. CONSTITUTION:A sample is stuck on a test paper part 51, then a test stick 5 is inserted into an insertion groove part 13, and the coloration test paper part 51 is exposed in a comparison window 33 through an insertion opening part 35. The wheel 2 for operation is rotated for a color comparison between a color sample part 21 for the comparison and coloration test paper part 51. When each stage color comes to right below the coloration test paper part 51 through the rotation of the wheel 3, information that the stage color has is converted into a 4-bit signal. Patterns 41 and 42 of the uneven code part 4 on the reverse surface of the wheel 2 press down a conversion switch and the visual coloration comparative decision result between the coloration test paper part 51 and color sample part 21 for comparison is converted into an electric signal and displayed on a liquid crystal display device.
