The reference wt. value calculation means 3 calculates the average wt. value of a predetermined number of articles to be weighed containing the article to be weighed and weighed successively immediately before each time when one article to be weighed judged to be within the tolerance range by the judging means is weighed by the weighing means 1 to set the same to a reference wt. value. |
