  • Patent number: 12130167
    Abstract: A remedy judging system includes a weight checking device and a judgment unit. The weight checking device checks the weight of weighed product discharged from a weighing device. The judgment unit makes a judgment relating to remedies for the weighing device on the basis of “correct weight,” “overweight,” and “underweight” checking results, relative to a predetermined weight serving as a norm, obtained by the weight checking device. The judgment unit makes the judgment on the basis of determination patterns having an “underweight” checking result and at least one checking result that consecutively follows the “underweight” checking result.
