PURPOSE:To simplify display confirmations and to ensure operations, by inputting unit weights or number through keys and prohibiting further key input under a condition where total numbers of weighed goods are displayed. CONSTITUTION:A scale pan 3 connected to a loadcell, a keyboard 4, and displaying device 2 are provided to the main body of a scale 1. A CPU31 fetches weight data from a scale section 34, key input from the board 4, and condition data from a circuit 37. When the unit weight of goods is inputted through a unit weight key 14 and a ten-key 12, the weight is displayed in an indicator 6. Moreover, when numbers are inputted through the ten-key 12, the numbers are displayed in another indicator 7 and, at the same time, the unit weight is calculated and displayed in the indicator 6. In the state that the total number of weighing goods is displayed in the indicator 7 by operating a set key 15, inputs of numbers into a ten-key memory through the key 12 and the input of unit weights into the ten-key memory through keys 14 and 12 are prohibited. |
