PROBLEM TO BE SOLVED: To enable a weight sorting device to sort articles from a large-mass article to a small-mass article with the accuracy corresponding to the masses of the articles. SOLUTION: An amplification degree changing means 31 makes the amplification degree A of an amplifier 23 smaller as the upper limit value Gb of a mass range set in a discriminating means 27 from an inputting means 28 becomes larger, and a conversion factor changing means 32 makes the conversion factor of a converting means 25 larger as the upper limit value Gb of the mass range inputted from the inputting means 28 becomes larger.
