Abstract

PURPOSE:To provide the titled device with a function selecting a character from the combination of radicals to form a document and expanding and contracting characters or a composition when necessary by inputting radicals of the characters. CONSTITUTION:A complex radical is inputted from a radical selecting area 17, a simple radical is written in a recognizing area 16 and these radicals are recognized by a recognizing circuit 6. A composing circuit 9 determines a character by combining radical codes sent from the recognizing circuit 6 or a radical selecting circuit 7. A character code corresponding to the combined character is sent to an editing circuit 10 and the character is displayed on a display device 12. A function selecting circuit 8 decides a specified function out of functions sucn as , , large and small arrayed in a function area of a tablet 1. A signal corresponding to a function specified by a stylus pen 3 is sent to the editing circuit 10 to move, expand or contract the character displayed on a display device 12.

Description

[Detailed Description of the Invention] [l''11 Field of the Invention The present invention is directed to inputting Japanese words and phrases containing a mixture of kanji, kana, alphanumeric characters, symbols, etc., and inputting this information stored in a device on demand. This invention relates to a document creation device that edits the text as appropriate to create a text and prints the text.

[2] Prior Art When inputting words and phrases in Japanese into a document creation device, there are methods such as manually touching kana, kanji, etc. on the board, inputting using multi-stage shift keys, or converting kana and kanji.

[8] Problems with the prior art In the prior art, training is required no matter which method is used manually, and a method has also been proposed in which characters are written on a tablet and the characters are recognized based on the stroke order. There is, but it has not been put into practical use.

[4] Purpose of the Invention The purpose of the present invention is to solve the above-mentioned problems of the prior art, and to create a document by selecting characters from combinations of characters by inputting character radicals (Kanji bias, labor, etc.). Along with doing
To provide a document creation device that also has a function of enlarging or reducing characters or sentences as necessary.

[5] Contents of the Invention The contents of the present invention will be explained using FIGS. 1, 2, and 3.

In FIG. 1, a sheet of paper 2 is placed on a tablet 1, and characters such as kanji, kana, alphanumeric symbols, etc. are written on the sheet of paper 2 with a stylus pen 3. 44 is a coordinate reading circuit that scans and reads the x, y, and Z coordinates of the pen 3 at regular time intervals; as for the Z-axis reading value, when the pen 3 is in contact with the paper 2, Z=1; When it is away from paper 2, it is determined that Z=Q. The coordinate classification circuit 5 classifies into those to be recognized based on the X, Y, and Z coordinate positions of the pen 3, and those indicating functions such as cursor movement and change of character size.

An example of the above-mentioned division will be explained using FIG. 2.

In other words, the surface of the tablet 1 is divided into a radical selection area 14 in which complex radicals are arranged, and a function area 15 related to functions such as moving the cursor or switching the size of characters.
, and recognition area 1 that recognizes the radical of the written character.
Classified into 6.

The coordinate classification circuit 5 selects the radical selection area 14 or the function area 1 from the pen coordinates X and Y coordinates Z-1.
5 or the recognition area 16, and sends the X and Y coordinate values of the pen to the radical selection circuit 7, function selection circuit 8, or recognition circuit 6, respectively. The radical selection circuit 7 selects which radical corresponds to the pen coordinates sent from the coordinate division circuit 5, and sends the corresponding radical code to the synthesis circuit 9. For example, in FIG. 2, it is determined that the coordinates of the pen are 1 ryo at the top left of the radical selection area 14, and the corresponding radical code is sent to the synthesis circuit 9. The recognition circuit 6 recognizes the radical of the written character from changes in the pen coordinates of the recognition area 16 sent from the coordinate classification circuit 5.

In the present invention, in order to simplify the recognition of radicals, the pen movement directions, that is, the force strokes and directions of the line segments, are divided into eight types as shown in FIG. This division may be further finely divided into 16 or 32 divisions if necessary. It also calculates the length of the line segment from the coordinates and recognizes the radical from the direction and length of the line segment. For example, when recognizing "A" in FIG. 4, the direction of the line segment from 2] to 22 in FIG. 4 (1) becomes f according to the classification in FIG. The line segment up to is g
becomes. These relationships are shown in FIG. 4 (2). Next 21
If the length 1 of the line segment from to 22 and the length 12 of the line segment from 23 to 24 are found from the coordinates, then f and 11°g
and 12, the character "i" is recognized and the radical code corresponding to the recognized radical is sent to the synthesis circuit 9.

In addition, if all radicals are recognized by the recognition circuit 6, the radical selection area 17 and the radical selection circuit 7 may be omitted, but the recognition circuit 6 will be complicated and the device will be expensive. Undesirable. Therefore, in the present invention, complex radicals are manually entered from the radical selection area 17, and simple radicals are written in the recognition area 16 and recognized by the recognition circuit 6.

The synthesis circuit 9 combines the radical codes sent from the recognition circuit 6 or the radical selection circuit 7 to determine a character. For example, if radical codes corresponding to ``i'' and ``hi'' are sent, the combination of these is determined as ``ka'', and the character code corresponding to this character ``ka'' is sent to the editing circuit 10, which results in 10
sends the input character code to the display device 12 and displays the character.

The function selection circuit 8 selects "=", "-", and "thick" arranged in the function area 15 of the tablet l-1.
This is to determine which of the functions such as "small" has been instructed. That is, when pressed by the stylus pen 3, Z=1, and it is determined from the X and Y coordinates at this time which function is requested. r-J r-J is the movement of the cursor on the display surface of the display device 12, "thick"
"Small" means all enlargement and reduction of letters, etc. The function selection circuit 8 sends a signal corresponding to the function instructed by the stylus pen 8 to the editing circuit 10 to move, enlarge, or reduce the characters displayed on the display device 12.

When the manual input of characters to the editing circuit IO is completed, the printing device 11 prints as necessary to obtain a clean sheet 13.

In the explanation so far, only the manual input of radicals has been explained, but kana characters can also be input from the recognition area 16 and the radical selection area 14, and Japanese sentences can be created.

Furthermore, although the document creation device of the present invention has both a radical selection means and a recognition means, it goes without saying that there may be cases in which either one of the means is sufficient. With the document creation device, you can easily create Japanese text including kana characters, symbols, etc. by inputting the radicals of kanji and selecting kanji from this combination.

By using such a radical input means, the recognition circuit becomes simple, and the device can be expected to be miniaturized and economically advantageous.

[7] Possibility of industrial use The document creation device of the present invention can be used in Japanese word processors, real-time character recognition devices, intelligent terminals that perform input in Japanese, and the like.
