PURPOSE:To shorten a collective discharge time by switching continuous discharging operation to combinational discharging operation when the difference between the target weight of bodies to be weighed and the total weight of bodies to be weighed which are discharged continuously enters a range wherein bodies to be weighed are handled at a time by one-time combining operation. CONSTITUTION:When the value obtained by subtracting the total weight value of bodies to be measured which are discharged continuously from target weight reaches the weight value where bodies to be weighed are handled at a time by one-time combination selecting operation, the continuous discharging operation is stopped and a combination calculation part 38a starts combining operation. A combination selecting circuit 38 compares the weight of a combination with the stored value in a storage device, and a discrimination part 38b selects a combination which is closest or equal to the weight and sends out its discrimination signal corresponding to a selected weighing hopper to a discharge supply controller 40. Consequently, the bodies to be weighed in the combination-selected weighing hopper are discharged and a timing hopper 20 is opened, so that the bodies to be weighed which are as many as the target weight are put in a packaging machine 21 and packaged together.
