An automatic weigher with a plurality of article batch handling units arranged in a circular formation is controlled by a single computer to perform two or more mutually independent combinational weighing operations. In order to allow different articles to be weighed, a dispersion feeder separable into individually vibrating table units with adjustable partition walls is provided at the center. For improving the efficiency of combinational weighing operations, each article batch handling unit is provided with a memory hopper and the computer is programmed to generally give higher priority to memory hoppers than to weigh hoppers such that memory hoppers are generally more likely to be selected by the combinational computations. The computer is also programmed to identify article batch handling units in which the total weight of article batches in the memory hopper and weigh hopper is less than a critical value and to combine their article batches.
