IPC: G01N21/35
Filed: 2002-04-22
Abstract: <P>PROBLEM TO BE SOLVED: To improve the stability of discriminating the quality of a sheet.  <P>SOLUTION: In a method for discriminating the quality of the sheet, a sheet to be discriminated is irradiated with a short wavelength light having 370 nm and a long wavelength light having 420 to 1,000 nm in the case of discriminating the quality of the sheet. The quality can be discriminated by the absorbance difference of the sheets obtained for the illuminated light. Since the absorbance of the sheet is mutually different depending on the quality of the sheet, the quality can be discriminated without being affected by an influence due to the difference of manufacturing steps like a density pattern. The influence of the environmental factor such as a humidity or the like and the deterioration or the like of the sheet to the absorbance can be suppressed by adopting both the short wavelength light and the long wavelength light. As a result, the stable quality of the sheet can be discriminated.  <P>COPYRIGHT: (C)2004,JPO
