Input and display apparatus for handwritten characters
First Claim
1. An input/display apparatus for handwritten characters, including a display provided with a display surface in which orthogonal coordinates are defined and an input device having a light transmitting input surface in which orthogonal coordinates are defined, which outputs coordinate points indicated by a special indicating device, on the input surface disposed so as to overlap with the display surface, coordinate points being displayed on the display surface of the display, corresponding to a plurality of coordinate points indicated at a time of handwriting input by the special indicating device, the input/display apparatus for handwritten characters comprising:
- cursor display means for displaying a cursor indicating a position for input/display on the display surface of the display;
stroke data preparing means for preparing stroke data, including coordinate points extracted after an end of handwriting input from among a plurality of coordinate points outputted from the input device at the time of handwriting input on the basis of a predetermined reference; and
normalization display means for displaying the prepared stroke data at orthogonal coordinates having predetermined dimensions which are defined in an area after the displayed position of the cursor.

Abstract
An input/display apparatus for handwritten characters is capable of quickly inputting handwritten characters, freely editing characters inputted, and storing a lot of handwritten characters with a limited storing capacity. On a display panel provided with a display surface, the orthogonal coordinates of which are preset, a touch panel provided. An input surface of the touch panel, the orthogonal coordinates of which are preset, is disposed in such a way that the display surface and the input surface overlap each other. When the input surface is indicated with an input pen, the indicated coordinate point is outputted. At the time of handwriting input, when the input surface in the input/display area for characters is continuously indicated, coordinate points on the display surface corresponding to the plurality of indicated coordinate points are displayed. After the handwriting input is over, stroke data consisting of coordinate points extracted on the basis of predetermined references from among a plurality of coordinate points outputted from the touch panel at the time of handwriting input are prepared. The stroke data are displayed by being converted to a size corresponding to the width of the line set in the area after the display position of the cursor.
