PURPOSE:To improve workability operational properties, and reliabilites of operation, by performing confirmations and clearances on sums of calculated numbers through key operations. CONSTITUTION:A CPU31 controls each section based on data from an ROM32 and an RAM33, and fetches weight data from a scale section 34, key inputs from a keyboard 4, and condition data from a circuit 37. Moreover, the CPU31 controls an indicating section 41 composed of a scale weight indicator 5, a unit weight indicator 6, and a number indicator 7, and a lamp lighting circuit 43. When a call key 18 is independently operated after cumulating total numbers of weighed goods by operating an add key 16 after operating a set key 15, a summed number is confirmed. Moreover, when a memory clear key 19 is independently operated, the summed number is cleared. Also, unless an eliminate key 13 is operated after operating the set key 15, processings through key inputs are prohibited by stopping inputs through the unit weight key 14 and a ten-key 12. |
