发明名称 INPUT/OUTPUT DEVICE AND INPUT DISPLAY SYSTEM
摘要 <p>PURPOSE:To obtain a coordinates output in which the followability of a display and, further, a display quality to an input are improved even when a character and a graphic are inputted at high speed with a handwritten image by outputting only arbitrary several coordinates data out of detected coordinates. CONSTITUTION:When a user is inputting the graphic, etc., since the coordinates data outputted from an input/output device 1 to a host computer 2 are the coordinates at random, dots to be displayed are made at random, but a display with good followability is executable. Further, when the user completes the input, since all coordinates detected by an XY coordinates detecting circuit anew are outputted, spaces between the dots made at random can be displayed as though smoothing is gradually executed from a point where the input is started, and an contradictory feeling is not given to the user. Thus, even when the character and graphic are inputted at high speed by the handwritten image, the coordinates output, in which the followability of the display and, further, the display quality to the input are improved, can be obtained.</p>
