PURPOSE:To rationalize the space in an input operation part, by operating a printed character erasing key and numeral keys in combination, memorizing the printed character erasing position data, and automatically erasing a printed character column based on said data. CONSTITUTION:The output from the input operation part 10, into which data required for computation is inputted, and the output from a weight detecting part 20, which generates an electric signal corresponding to the weight of a material to be measured, are applied to a central processing unit 30. The CPU30 performs price computation, printing character erasing, and the like, and outputs the computed results to a display part 40 and a printing part 50. When the printed characters in a unit price column and a net quantity column are erased, the printed character erasing key 13 and the numeral keys 12, which specify the printed character erasing positions in the net quantity column and the like, are operated, and the results are inputted into an RAM50. |
