摘要：PURPOSE:To count articles accurately by regulating updating from unit weight to new unit weight when finding the unit weight from the weight of numbers of articles. CONSTITUTION:Data on the weight numbers of articles measured by weighing machines 11-1n are supplied successively to an A/D converter 3 through a multiplexer 2, and are inputted to an arithmetic part 4 after being converted. On the basis of the supplied measured-value signal, the control part 4 performs combined arithmetic to calculate the combined weight. This combined weight is divided by the quantity of a quantity setting part 6 to calculate new unit weight. This new unit weight, only while between set values of an upper limit unit weight setting part 7 and a lower unit weight setting part 8, is used as new unit weight for the following calculation of a quantity. Thus, the unit weight is updated to count articles accurately.
