PURPOSE:To know the unknown number of samples accurately and quickly by renewing the memory content of a register with the calculated number of the samples and by making an average unit weight renewed automatically according to the renewed memory content of the register. CONSTITUTION:When a known number is keyed in the reigster 11 through the intermediary of a ten key 10 and a key 25 is operated, an artithmetical unit 18 calculates an arithmetic mean for several lots, while a dividing unit 9 calculates the average unit weight and makes a register 12 hold the same. Next, the number of small samples which is supposed to be slightly larger than the known number is calculated and the content of the register 11 is renewed with the number thus calculated. The arithmetical unit 18 and the dividing unit 9 calculate an average unit weight on the basis of the renewed content of the register 11, renewing the memory content of the register 12 to be the newest. |
