<p>PURPOSE:To reduce burden on the processing of a computer and to constitute a handwritten picture processing system on the computer by converting coordinate values of a stylus pen to picture data and transmitting this data to a host computer. CONSTITUTION:When receiving a handwritten picture data origin coordinate value changing command from a host computer CP 9, an origin set instructing part 8 sets an initializing flag 7. The input of the stylus pen is detected by an input coordinate detecting part 1, and a handwritten data transmission part 6 sends a pen down signal to the CP 9. The detecting part 1 sends coordinate values of the pen to an initializing processing part 2 until detecting a pen up signal. Only when the flag 7 is set, the processing part 2 sends input coordinate values to a sign inverter 4 and an adder 3 and resets the flag 7. A handwriting input device 10 sends the result of addition of the coordinate value from the detecting part 1 and contents of an origin coordinate register 5 until receiving the picture data origin coordinate value changing command signal from the CP 9.</p> |
