A combination weigher comprising: a plurality of weighing hoppers wherein each of said hoppers includes two weighing chambers (4a, 4b) and is capable of weighing objects to be weighed which have been fed to one of the two weighing chambers, the weighing chambers being capable of independently discharging the objects; a plurality of feeding means which are disposed above the weighing hoppers to respectively correspond to the weighing hoppers, for selectively feeding the objects to each of the two weighing chambers of a corresponding weighing hopper; and a control means which is configured to perform combination calculation based on weight of the objects which have been fed into the weighing chambers (4a, 4b) of each of the weighing hoppers to select weighing chambers forming a combination which have been fed with the objects whose total weight falls within a predetermined weight range, and which is configured to cause the selected weighing chambers to discharge therefrom the objects; wherein each of the feeding means is configured to, when the combination calculation and the discharging of the objects are repeated, feed the objects to only one of the two weighing chambers (4a, 4b) of the corresponding weighing hopper in a time period from combination calculation being performed currently to combination calculation being performed next; characterised in that the control means is configured to perform the combination calculation in such a way that the number of the weighing hoppers whose weighing chambers (4a, 4b) are both selected simultaneously to form the combination is limited to a predetermined number or less, wherein the predetermined number is one. a plurality of weighing hoppers wherein each of said hoppers includes two weighing chambers (4a, 4b) and is capable of weighing objects to be weighed which have been fed to one of the two weighing chambers, the weighing chambers being capable of independently discharging the objects; a plurality of feeding means which are disposed above the weighing hoppers to respectively correspond to the weighing hoppers, for selectively feeding the objects to each of the two weighing chambers of a corresponding weighing hopper; and a control means which is configured to perform combination calculation based on weight of the objects which have been fed into the weighing chambers (4a, 4b) of each of the weighing hoppers to select weighing chambers forming a combination which have been fed with the objects whose total weight falls within a predetermined weight range, and which is configured to cause the selected weighing chambers to discharge therefrom the objects; wherein each of the feeding means is configured to, when the combination calculation and the discharging of the objects are repeated, feed the objects to only one of the two weighing chambers (4a, 4b) of the corresponding weighing hopper in a time period from combination calculation being performed currently to combination calculation being performed next; characterised in that the control means is configured to perform the combination calculation in such a way that the number of the weighing hoppers whose weighing chambers (4a, 4b) are both selected simultaneously to form the combination is limited to a predetermined number or less, wherein the predetermined number is one.
