摘要

PROBLEM TO BE SOLVED: To judge the quality of a carton blank certainly even if the feed quantity per unit time of the carton blank is relatively much and to efficiently sort good and bad articles. SOLUTION: In such a constitution that counter parts 68a1 are respectively connected to the respective photoelectric tubes 32 of a photoelectric tube unit 32 for sending out a detection signal corresponding to the shape of a fed sheet material 6, a dimension operating part 72 for operating the shape dimension of an article to be inspected calculates the shape dimension of the article to be inspected on the basis of the data of the integrated number of pulses from the counter parts 68a1 and the feed distance of the article to be inspected per the number of pulses and a comparison part 76 compares the dimension data from the dimension operating part 72 with predetermined reference dimension data to output comparison output to a judge part 77.
