A coordinate input string (stroke information) detected by a coordinate input device (tablet) 1 and a stylus pen 2 is first inputted to a hand-written paper recognition device 9. Then a character recognition means 5 to recognize hand-written characters and a figure recognition means 6 to recognize hand-written figures are separated from the stroke information, by a threshold learning means to learn an input and calculate a threshold and a stroke separation means to separate a character stroke and a figure stroke, and transmitted.
