A combination balance, wherein a bag storing time required for storing weighed objects dropping from a collecting hopper (4) in a bag when the gate of the collecting hopper (4) is always open is longer than a sealing stop time between a time when the sealing of any one bag at its lower end when bags are manufactured in order by a packaging machine (21) is completed and a time when the sealing of the bag at its upper end is started. A control part (10) controllably closes the gate of the collecting hopper (4) immediately before at least a part of the weighed objects discharged from a weighing hopper (1) reaches the collecting hopper (4) and opens it before all the weighed objects reach the collecting hopper (4) and after a specified time after the gate of the collecting hopper (4) is closed. Thus, the bag storing time can be shortened within the sealing stop time of the packaging machine by closing the gate of the collecting hopper (4) for the specified time.
