OBJECT DESCRIPTION OF THE INVENTION · TECHNICAL FIELD OF THE INVENTION The present invention relates to _ <, by receiving-directing" optical inductive handwriting input device, particularly for tracking, and by recognizing the movement = surface The reflected light detects the moving λ device to form the optical sense of the handwriting: two, the moving track is wheeled into the digital electronic... eight handwritten wheeled device. [Prior Art] ^Used the handwriting wheel for computer use _, writing the tablet with a sensor pen; Ge=set' is usually a magnetic induction hand. The tablet is matched with a sensor. 3, for a handwriting with LCD display, please refer to the first figure, its 1 board with the schematic diagram of the sensor pen. / By 糸, know the handwriting number of the magnetic induction handwritten digital tablet b (hereinafter referred to as ^ know 'this kind of magnetic sensing, because the sensor pen P does not: will: I "used magnetic handwriting board") in use Obstruction or stroke, and only the trajectory of the panel that is fitted to the panel B is shown. For example, when the monthly subscription is written from the display screen of the host C connected to the display board, the number is used on the screen. However, when the user uses the feather, ρ to make a multi-stroke pattern or a text two magnetic tablet, and the sensor pen strokes to continue or continue writing,忐: Into the day, the correct method of the correct connection of the thermal method, the use of the equivalent:: to the trajectory data in the computer is not otherwise, for the use of Lrri #. For the CD_ not handwritten tablet, the 6 200809635 can display the strokes of the user. However, its cost is extremely high and the price is expensive. The average user cannot afford it.
