(B) Conventional technology Conventionally, in a character processing device, by operating an input device such as a keyboard, the characters in a typeface such as Gothic typeface or Mincho typeface stored inside are displayed. It is possible to create a sentence by creating the sentence and printing with those fonts. Recently, a character processing device that can print cursive characters stored in advance has been known.

(C) Problems to be Solved by the Invention However, even in a character processing device capable of printing cursive characters, the types of fonts that can be used for printing are larger than in the case of one type of Mincho font, for example. However, cursive characters are of preset fonts, and even if the number of types of cursive characters is increased, if the user wants to utilize the individuality of the characters handwritten,
It wasn't valid.

With the above configuration, the characteristics of the handwritten characters written by the user are reflected in all the printed characters.

(E) Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings, but the present invention is not limited to the following embodiments.

FIG. 2 is a block diagram showing the configuration of the embodiment of the present invention.

In FIG. 2, reference numeral 10 denotes a central processing unit, which stores, for example, an 8-bit microcomputer, a program storage unit for storing a text editing control program, and a control program for controlling each device described below. The storage unit and the interface with each device. 11 is a keyboard, for example, kana / alphabet keys, numeric keys, and function keys for selecting various functions required for writing sentences are arranged, and the character code is stored in the character code memory corresponding to the operated key.
Output to 12. The character code memory 12 stores the character code from the keyboard 11. A display device 13 has, for example, a CRT as a display screen, and displays texts input from the keyboard 11 and processed by the central processing unit 10 and information indicating the various functions described above on the display screen. The display device 13 may have an LCD panel as its display screen. 1
4 is a tablet which is a drawing input device, 15 is a handwriting recognition device, which recognizes handwritten characters by a signal from the tablet 14,
The handwritten character data is output to the handwritten character memory 16. The handwritten character memory 16 stores handwritten character data. A vector font memory I 17 stores a vector font of a font pattern of standard characters. A vector control unit 18 is a handwritten character memory 16 for extracting standard vector data input from the vector font memory I17 by the central processing unit 10.
Handwritten fonts and vector font memory I1 stored in
Change based on the difference between the standard character font stored in 7,
The changed vector data is stored in the vector font memory II19. A dot expansion device 20 expands the vector data input from the vector font memory II 19 into a dot pattern of characters for printing and displaying. Reference numeral 21 denotes a printing device, which outputs a character having the characteristics of a handwritten character input based on a signal from the dot development device 20, onto a printing paper.

Although not shown, the central processing unit 10 and each of the above components are connected to each other via a system bus 22 so as to exchange signals.

Next, the operation of this embodiment will be described with reference to FIGS.

First, the contents stored in the vector font memory I17 will be described.

As shown in FIGS. 4 and 5, the vector font memory I17 stores numbered parts which are strokes forming a character and vector data corresponding to the character code. The vector data is composed of a part number and position information of the start point and end point of the part specified by the part number. The data shown in FIG. 5 is vector data of the Chinese character "A". In FIG. 5, for example, in the vector data “1-2,2-2,23”, the horizontal bar of the part number 1 indicates “1,”
It means to draw from "2,2" to "2,23" in the coordinates as "1".

FIG. 3 is a flow chart showing the operation of creating vector data stored in the font memory II19.

First, the user inputs a specific character among the standard characters sequentially displayed on the screen of the display device 13 from the tablet 14 in order to memorize the characteristic (habit) of the character written by himself / herself (steps 100 and 101). The handwritten characters input from the tablet 14 are subjected to pattern recognition by the handwriting recognition device 15,
It is stored in the handwritten character memory 16. When handwritten characters have been input for all specific characters (for example, about 10 characters), the number of input vectors (the number of input vectors) is compared with the number of vectors of the specific character (the number of internal vectors) ( In step 102), it is determined whether they match (step 103). If the numbers of the respective vectors match, the input vector and the internal vector are associated (step 10).
Four). This correspondence is combined so that the total sum of (internal vector start-input vector start) ² is minimized. If the number of vectors does not match, the input vector corresponding to the internal vector is extracted (step 105),
A large number of vectors is associated with a small number of vectors. Similar to the above, the correspondence is made so that the sum of squares of the differences between the respective vector starts is minimized. If there are more internal vectors, the uncorrelated internal vectors are deleted (step 106).
On the contrary, if there are many input vectors, the parts No. start (start point) and end (end point) positions of the uncorrelated vectors are obtained and added (step 107).

After the above steps 104 to 107 are executed, the difference between the corresponding vectors is extracted, and the calculation of (input vector start position-internal vector start position) x α + internal vector start position is performed to update the internal vector data ( Step 108). The updated vector data is stored in the vector font memory II19. Α in the above calculation is set to a value of 0 <α ≦ 1. Then, similar to the above, the vector end position is calculated, the vector data is updated, and the vector font memory II
Remember in 19.

The font difference between the handwritten character and the standard character in the specific character extracted as described above is reflected also in the vector data of the remaining standard characters, and the updated vector data is stored in the vector font memory II19.

FIG. 6 is a flow chart showing the operation in the case of printing output using handwritten characters.

Prior to printing, input a sentence to be printed out (step 110). The input text is stored in a normal text memory (not shown). When the text input is completed, the print key is operated (step 111). By this key operation, the character code is extracted from the text memory one by one (step 112), and the vector font corresponding to the character code is extracted from the vector font memory II19 (step 113). Next, the taken-out vector font is developed into a designated dot pattern by the dot developing device 20 (step 114). This development of the dot pattern is repeated until there are no more characters to be taken out. When there are no more characters (step 115), the dot pattern is output to the printer 21 (step 116), and the input sentence is printed out.

Since the handwritten characters that have been dot-patterned by the dot expansion device 20 prior to printing are displayed by transferring the dot pattern to the display device 13, the user confirms the sentence by the handwritten characters. be able to.

(F) Effect of the Invention According to the present invention, by inputting several kinds of characters by handwriting, the characteristics of the handwriting (for example, writing hiragana in small size, writing characters rising to the right, etc.) are compared with other characters However, since it can be reflected, it is possible to obtain a character processing device that can express the warmth of handwriting to the characters of a document used for personal use such as New Year's cards and summer greetings.
