PROBLEM TO BE SOLVED: To materialize combination at high probability by predicting satisfaction or failure of the combination in advance, and to provide thereby a combined weighing device capable of enhancing an operation rate. SOLUTION: When main combination is selected by main combination computation using weighting hoppers 16<SB>1</SB>-16<SB>6</SB>shown by a thick dot line of a symbol A as objects, precombination computation is executed using as objects pooling hoppers 15<SB>1</SB>, 15<SB>5</SB>for supplying weighing objects X, X to the weighing hoppers 16<SB>2</SB>-16<SB>4</SB>, 16<SB>6</SB>not selected and shown by a thin dot line of a symbol B, and the selected weighing hoppers 16<SB>1</SB>, 16<SB>5</SB>. When the precombination computation is not materialized as a result therein and when the unoccupied pooling hopper 15<SB>1</SB>exists in the objects of the precombination computation, a supply amount of a weighing object X<SB>13</SB>' from a feeder to the pooling hopper 15<SB>1</SB>is controlled to an amount to satisfy the precombination by the weighing object X<SB>13</SB>' and, for example, a weighing object X<SB>21</SB>held in the weighing hopper 16<SB>2</SB>.
