<p><P>PROBLEM TO BE SOLVED: To provide electronic equipment for outputting and displaying key input data and operation screen data corresponding thereto without any unnecessary key input operation. <P>SOLUTION: Key input data 13a9 corresponding to a key operation, a calculator keyboard image 13a5 and display screen data 13a4 of resultant calculating operation are displayed as output image data 13a8. A numerical expression is input by key operation of the calculator keyboard 13a5. When inputting a fractional expression "5/3<SP>2</SP>", for example, a fraction input key "a b/c" is input, followed by, "5", "x<SP>2</SP>" and "down arrow key" as a numerator, and then, as a denominator, when "2" is erroneously input as shown in a square M and a "DEL" key is input, the character of the "DEL" key is temporarily displayed, but deleted with the dominator value "2" which was input by mistake, and a correct dominator value "3" input later is displayed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
