PURPOSE:To make highly accurate counting possible at a high speed by mutiplying the weight values weighted in plural weighing cells by the prescribed number per prescribed weight and rounding the same to integers then multiplying these by the weight per number, combining and adding these values and selecting the combination equal to the prescribed weight. CONSTITUTION:There are a weight setter 14 which sets a prescribed weight W and a number setter 12 which sets a prescirbed number N, and dividers 18, 16 operating W/N and N/W are connected thereto. Further, a multiplier 20 which mutiplies the signal values obtd. by weighing the objects to be weighted which are roughly of the same weight respectively in plural weighing cells by N/W is provided and is connected to a multiplier 24 which multiplies these by W/N past a rounding to integer circuit 22. The multiplied values are combined are added by a combining device. For example, when the weighed signals W1-Wn are held through a standard weight conversion part 10 in sample holding circuits 30-1- 30-n, they are selectively added by the signal of a combination generator 32, and the combination signal which is decided to be equal or closest to the prescribed weight W is stored, and the objects to be weighed are discharged from the weiging cell corresponding to said stored value. |
