The text editing section has a function wherein the name of gesture command corresponding to a line drawing and the character to be edited are displayed by the screen when each line drawing is handwritten with respect to the screen. The pen input processing apparatus has a gesture command judging section for recognizing the gesture command in accordance with a trace coordinate of the line drawing.
