<P>PROBLEM TO BE SOLVED: To provide a device and a method for judging the folded quality of a wrapping paper which accurately, inexpensively and automatically judges whether the folded (and adhered) quality of a wrapping paper end is good or not on line while automatically a square shaped item comprising papers, panels or the like is packaged with the wrapping paper whose end is to be folded and adhered. <P>SOLUTION: This relates to a device and a method for judging the folded quality of a wrapping paper. A folded part is irradiated, the part irradiated is photographed by a camera, and a folding line is calculated from the picture obtained by the difference in luminance between the dark part and the light part of the folded part for judging if the difference between the result obtained from the calculation and a reference folding line set in advance is within the tolerance. <P>COPYRIGHT: (C)2004,JPO |
