<p>PROBLEM TO BE SOLVED: To input a curve, while erasing input errors vesus the manner in a conventional technique where inputting and erasing of a curve are separated as different sequences. SOLUTION: A means for temporarily switching from a curve inputting state 404 to an erasing state 407 is provided and a curve inputting procedure is drastically reduced by a method of erasing a part or all of a curve in the middle of inputting and inputting a part to be continued again. Thus, a desired curve can be inputted by once inputting of a curve and a single curve can be inputted as one object without later erasing a curve inputted with errors.</p> |
