PURPOSE:To increase a weighing speed, by operating a weight at every weighing product receiver on the basis of the weight value when products to be weighed are charged in N-pieces of weighing product receivers and the weight value when the products to be weighed are charged in (N+1)-pieces of the weighing product receivers. CONSTITUTION:A plurality of products to be weighed are received in intermediate hoppers 141-14n through a supply device 11, a circular feeder 12 and feeders 131-13n and allowed to fall to be received in one weighing hoppers 161, 163...162n-1 at first to be weighed. In this weighing state, the products to be weighed are again received in the intermediate hoppers 141-14n and other discharge gates 152, 154...15n are opened and the received products are allowed to fall to be received in the other weighing hoppers 162, 164...162n to be weighed. That is, the products to be weighed are received in either one of a pair of hoppers 16a, 16a+1 to be weighed and, next, the products to be weighed are also received in the other hopper and the total weight of the re ceived products of both weighing hoppers is weighed. Then, by subtracting the weight due to one weighing hopper from the total weight, the weight of the received products of the other weighing hopper is also weighed to make is possible to increase a weighing speed.
