PURPOSE:To improve the utility by altering unit price through ten-key inputting following designation of category and computing a price in the designated category based on the weight and the unit price altered. CONSTITUTION:As soon as a load is applied on a measuring base of a balancing section 30, a voltage signal is generated corresponding to the size of the load from a weight sensor 31 and inputted into a data processing section 34 by way of an amplifier 32, an A/D converter 33 and a data selector 37. CPU35 of the data processing section 34 controls a digit decoder 39 and a segment decoder 40 to have various indicators 6-9 to perform indications. Unit price is altered through ten-key inputting following the designation of category and a price is computed in the designated category based on the weight and the unit price altered. |
