A character input apparatus has a position input device for inputting coordinate values corresponding to a position indicated by contacting an input surface, a recognition processor for analyzing a coordinate value string sequentially input by the position input device to obtain a character code corresponding thereto, and a display device for displaying the character code obtained by the recognition processor. The character input apparatus includes a character size processor for discriminating a distribution range of the coordinate value string to obtain character size data corresponding to the size of the distribution range. A character is displayed on the display device in a character size corresponding to the character size data obtained by the character size processor. |
