PURPOSE:To perform accurate colorimetry, by applying tension on the colorimetry surface of a sample by mounting the sample on a base table, only bringing down an operating lever, and obtaining a uniform state automatically: and to cope with the change in thickness of the sample, by moving a supporting table up and down so as to adjust the height of the upper surface. CONSTITUTION:When an operating lever 4 is brought down, the lower edge of a longitudinal side 7 in a U-shape of the operating lever 4 is contacted with the inward facing slant edge surface of the upper end of an engaging pawl 9. When an operating part 14 is further pushed down, the engaging pawl 9 is pushed outward. The longitudinal side 7 is inserted into a groove 3 of a base table 1 with a sample 17 being compressed by the lower end. At the time of the insertion, the sample 17 is strongly pulled by the lower end of the longitudinal side 7. The central part of the sample 17 is fixed under the state tension is applied to a flat part 2 of the base table 1. An opening is formed in the flat part 2 of the base table 1. A supporting table 31 is inserted in the opening so that the table can be moved up and down and step by step. When the projected amount of the upper surface of the supporting table 31 becomes excessive, a knob 36 at the back surface of the supporting table 31 is operated so as to retract a pawl spring 34. Under this state, the supporting table 31 is pushed down. Thus adjusting is performed. The adjustment of the projected amount of the upper surface of the supporting table 31 from the surface of the base table can be made readily. |
