Abstract

PURPOSE:To attain the input of desired graphic character codes with operation of a cursor control key and without using a ten-key, by using a cursor storage means to store the position of a cursor set at an optional digit position of a code. CONSTITUTION:When a desired sentence, e.g., characters for recognition are produced, these characters are supplied by writing from a writing area on a tablet 1. Thus coordinate data is delivered to a recognizing part 2 from the tablet 1. The part 2 recognizes written characters one by one according to said coordinate data and sends the address information corresponding to the recognized character to a font memory 4. At the same time, the position information indicating the positions of characters is sent to a display part 3 with control of a cursor. The memory 4 sends font pattern data to the part 3 by the input address information. While the part 3 displays the font pattern, i.e., the input characters at the position of a display screen of the lower stage shown by the position information.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a character recognition device, and more particularly to a character recognition device in which a code can be directly input using cursor control.

(Prior art) A character recognition device that recognizes characters input by handwriting from a tablet in real time generally has a dictionary for recognizing characters, but this dictionary is used by dozens or even several people. Extract the characteristics of 100 people's characters and logically OR them.
It is formed in the form of

For example, if stroke order or number of strokes is taken as a characteristic of a character, data from dozens of characters or hundreds of characters may be used). (Due to the person's habits), the scribe assumes that the writing style is correct, so no matter how many times he or she writes it down, it will not be recognized as the correct character. In such cases, the JIS code of the character you want to input is generally A method of directly inputting the information is used.

When performing this method, the conventional character recognition device has a numeric keypad 13 on the tablet 1 as shown in FIG.
If the number of points is "m" and "n", inputting "m" and "n" using the numeric keypad 13 causes the display unit 3 to display the numbers.

(Problems to be Solved by the Invention) However, the character recognition device having the above configuration has the following problems.

On the tablet 1, which is the character input surface, there is a cursor control key (<←>) for editing input characters.

<↑>, <↓>, <→>), insert key and delete key
In addition to the operation keys 12 such as keys, it is necessary to have a numeric keypad 13 for directly inputting the J Engineering S code.

Therefore, it was necessary to increase the size of the tablet 1 or to narrow the writing area 11 on the tablet 1.

The present invention eliminates the above-mentioned problems and provides a character recognition device that does not require a numeric keypad and allows direct input of p.JIS codes using cursor control keys.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a tablet that includes a cursor control key and outputs coordinate data of written characters, a ratio of the tablet, and a writing method based on a force signal. In a character recognition device that has a recognition unit that recognizes characters, a font memory that stores font patterns, and a display unit that displays font patterns from the font memory based on the recognition result of the recognition unit, code storage means for storing a corresponding code; cursor storage means for storing the position of a cursor at an arbitrary digit position of the code; and a cursor storage means for storing a cursor position at a desired digit position of the code according to the operation of the cursor control key. code control means for displaying the code and the graphic characters of the code on the display section via a font memory by changing the contents of the code storage means in accordance with the contents of the cursor storage means and displaying the code indicated by the contents and the graphic characters of the code; It was established.

(Operation) According to the present invention, since the character recognition device is configured as described above, the technical means operates as follows.

In the graphic character input mode, the code control means first displays the code indicated by the initial value of the contents of the cursor storage means and the code storage means, the character of the code, and the cursor (for example, indicating the leftmost digit position of the code) on the display section. Work like you do.

Next, the code control means operates to change the contents of the cursor storage means in accordance with the operation of the cursor control keys (for example, in the left/right direction) and move the cursor to the digit position of the code to be changed. Further, the code control means changes the contents of the code storage means in accordance with the contents of the cursor storage means according to the operation of the cursor control keys (for example, up and down directions), and displays the code and character indicated by the contents via the font memory. section. That is, it works by changing the value of the digit of the code where the cursor is located, and displaying the changed code and its characters. In this way, it is possible to input a desired graphic character by setting the displayed code to a desired value by operating the cursor control key, so the problems of the prior art described above can be solved. be.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a diagram showing details of the tablet surface and the display surface of the display unit. Reference numeral 1 denotes a tablet, which has a writing area 11 for inputting handwritten characters, and operation keys 12 including a cursor control key, a mode> key, and the like. 2 is a recognition unit that recognizes written characters from the coordinate data from the tablet 1; 3 is a recognition unit that displays input characters, etc. on the upper display screen 31 in the mode in which JIS codes are directly input; and in the mode in which written characters are input, the input characters, etc. 4 is a font memory that provides fonts, master data, and data to the display section 3. 5 is a code control unit which is a characteristic part of the present invention, and in the mode for directly inputting JIS codes, operation key 1 is pressed.
A code corresponding to the JIS code is created by inputting the cursor control key 2, and address information corresponding to the code is output to the font memory 4. Reference numeral 6 denotes a memory controlled by the code control unit 5, which includes a cursor register 61 that stores the cursor position at the digit position of the code (here, 4 hexadecimal digits) corresponding to the JIS code, and 16
It has a code register 62 that stores a base number code.

Next, the operation will be explained according to the flowchart shown in FIG.

First, to create a required sentence, for example, 6-character recognition, by inputting each of these characters in writing from the writing area 11 on the tablet 1, coordinate data is output from the tablet 1 to the recognition unit 2. The recognition unit 2 performs a process of recognizing written characters character by character based on this coordinate data, sends address information corresponding to the recognized character to the font memory 4, and also sends position information indicating the character position using cursor control. The font memory 4 sends the font pattern data to the display section 3 based on the input address information.The display section 3 displays the font/main turn, that is, each Display input characters.

In the above written character input mode (Sl), it is assumed that among the 6 characters recognized in the above sentence, the character ``recognized'' could not be input no matter how many times it was written. (In kanji,
There are many cases of memorizing kanji by mistake.

For example, many people remember that ``1 hat'' is written as ``+N'' with the day doubled. In this case as well, as in this example, the person has memorized the characters incorrectly and thinks that it is the correct way to write them, so no matter how many times they are written, the characters are not recognized as the required characters. ) In such a case, by pressing the ←> key or the ←> key of the cursor control key on the operation keys 12 of the tablet 1, the lower cursor 32m is moved via the recognition unit 2 to the position of a character that cannot be input, that is, the 6th character. Set between `` and 6 sense'' (S
2). Next, by pressing the ``Mode'' key on the operation key 12, a mode is entered for directly inputting the JIS code (S4).

When the code control unit 5 detects the pressing of the ``Kokumode'' key, the code control unit 5 uses the font memory 4 to display the mode.
For example, 6 code input” is displayed on the upper display screen 31 of the display unit 3.
At the same time, a 4-digit hexadecimal code corresponding to the JIS code indicated by the initial values of the cursor register 61 and code register 62 and the corresponding characters are displayed at the position displayed as "6 code input" via the font memory 4. Display on the right.

For example, assume that the 4-digit code stored in the code register 62 is "3021'(H)" as an initial value, and the cursor register 61 stores the leftmost number 3". Note that (H) indicates hexadecimal. Therefore, the code control unit 5 sends the four-digit code indicated by the contents of the code register 62 and the address information of the corresponding character "A" to the font register 4, and also displays the cursor control information according to the contents of the cursor register 61. Part 3
``Code person crab 021 sub'' is displayed on the upper display screen 31 (S4).

Next, in accordance with the pressing of the cursor control key ←> key or <→> key on the operation key 13, the code control unit 5 changes the contents of the cursor register 61 as shown in FIG. , move the upper cursor 31a to the desired digit position of the four-digit code (S6). However, if the <←> key is pressed at the leftmost digit position, or if the ←> key is pressed at the rightmost digit position, the upper cursor 31a is not moved. Is the upper cursor at the changed digit position of the 4-digit code? 1a, the code control unit 5 changes the contents of the code register 62 in accordance with the pressing of the cursor control keys <↑> key and ↓> key, and moves the 4th
As shown in Figure (b), the code of the digit of the upper cursor 31a of the four-digit code is set to a desired code (S7). The code changes at each digit position from 0 (H) to F
Until (H), press the <↑> key +1, <↓>
-1 when the key is pressed. 0(H) and F(H) are connected and changed.

As described above, by operating the cursor control keys, the code control section 5 can be used to control the code 4, which requires a 4-digit code corresponding to the JIS code (graphic character code).
727 (H) and displays the character corresponding to this code (s8).

That is, "Code 4727 approved" is displayed on the display screen 31 at the top of the display section 3. Note that if there is no character corresponding to the set four-digit code, the code control unit 5 displays a special code such as ``medical'' on the display unit 3 to warn the operator.

Next, when the FULL MODE> key on the operation key 12 is pressed again, the code control unit 5 detects that the FULL MODE> key has been pressed again and transfers the contents of the code register 62 to the recognition unit 2. The recognition section 2 sends the address information indicated by this content (4727) to the font memory 4, and thereby inputs the character "OK" at the position of the lower cursor 32a on the display section 3 (S5, S6). Then, the mode for directly inputting the JIS code is canceled, and the mode returns to the mode for inputting normal written characters.

As described above, according to this embodiment, the cursor control keys <←>, <↑>, and <↓> do not require a numeric keypad.

The required JIS code (graphic character code) can be input using only <→>, and the required area of the tablet or the number of keys can be reduced.

In addition, in this example, the JIS code of the character you want to input is 1
Although the method of operating in hexadecimal 4-digit format has been described, it goes without saying that the JIS code can be similarly set in the form of ward and point numbers using only the cursor control keys.

You can also use ←> and <↑> as cursor control keys.

An example using four types of keys, ↓> and <→>, has been given, but it is also possible to use flow control to combine left and right keys into one, and up and down keys into one.

(Effects of the Invention) As explained above, according to the present invention, the required graphic character code can be input by operating the cursor control keys without the need for a numeric keypad, so it is possible to downsize the tablet. At the same time, the tablet surface can be used effectively.
