Abstract
PURPOSE: To realize improvement in precision and fast character recognition by providing the pen of a handwitten-character input unit itself with a function of moving-direction detection.
CONSTITUTION: Rotary disc 13 centering on axis 12 of pen 1 is provided with one window 14 in its radius direction. Once tip axis 12 of pen 1 starts drawing curve M, paper surfaces 2 is irradiated with light from light source 18 and reflection signal of a character stroke strikes rotary disc 13 through window 14, so that the direction of the character direction can be detected. Since the quantity of reflected light decreased when light reflected from the calligraphic curve M passed through window 14 provided to rotary disc 13, a constant supervision over the rotation angle of motor 15 turing rotary disc 14 is exercised so as to make it possible to detect at any time the segment direction (the moving direction of the pen) of the character stroke judging from the rotation angle when the quantity of the reflected light decreases.
