PURPOSE:To perform accurately and efficiently operation by annunciating that an estimated weight value after a desired time which is calculated by using a measured value is larger than a registered quantity to be scaled. CONSTITUTION:Data obtained by a weight detection part 1 is inputted to a control part 12 through an amplifier 10, processed by a CPU14 according to a program stored in a ROM13, and stored in a RAM15, and registration information from operation keys 16 is stored in the RAM15. Then, an expected quantity A and a desired time (T1<T2<T3) when the estimated weight value is calculated are registered with keys 16 and estimated weight values AT1, AT2, and AT3 which are set times T1, T2, and T3 later are calculated on the basis of variation in weight obtained by using momentary information from the detection part 1; when the value AT3 exceeds the quantity A, an annunciating lamp 17c turns on, and when the value AT2 or AT1 exceeds the quantity A, an annunciating lamp 17b or 17a turns on correspondingly.
