PURPOSE:To correct easily the result of drawing by incorporating a mirror converting function so as to form a drawing where the right and left are inverted. CONSTITUTION:The known operation is conducted based on the drawing data inputted by the operator and the coordinate points of a drawing on an imaginary coordinate system are calculated and stored once in a memory. Then, the operator gives a command whether the drawing of the normal mode is drawn via a keyboard or the like or the drawing of the mirror mode is drawn. In a normal mode, the step goes to MILFLG=phi and a microcomputer conducts the operating processing so as to convert the drawing data of the imaginary coordinate system into the drawing of the normal mode. Further, in case of the mirror mode, the step goes to MILFLG=1, the operation processing is conducted so as to obtain the drawing of the mirror mode.
