Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character recognition device that reads a plurality of character types.

FIG. 6 is a diagram showing an entry form used in a conventional device of this type, in which numeral 21 indicates an entry form;
2 is a character frame in which numbers should be written, 23 is a character frame in which katakana should be written, and character frame 22 and character frame 2 are
3 are distinguished by their coordinate positions on the entry form 21.

FIG. 7 is a diagram showing the configuration of a conventional device of this kind. In the figure, 24 indicates a character pattern input means for inputting a character pattern for one character, and 25 indicates in which character frame the character pattern is entered. 11 is a character type determining means for determining the character type of the character pattern based on information on the position of the character frame in which the character pattern is written; 26 is a numeric recognition means. , 27 is a katakana recognition means, 28 is a hiragana recognition means, and 29 is an alphabet recognition means.

In the above configuration, the character pattern input means 24
The input character frame position detecting means 25 detects in which position of the character frame 22 or the character frame 23 the input character pattern is located, and if it is detected that the character pattern is written in the character frame 22, the character type is determined. In the determination means 11,
The character pattern is determined to be a number, and is recognized by the number recognition means 26. As described above, in the conventional devices of this kind, the type of characters to be written in the character entry frame is determined in advance, and therefore the person filling in the text cannot freely select and write the type of characters.

In order to solve these drawbacks, this invention divides the character entry frame into multiple areas and changes the entry area for each character type, so that the type of character can be determined by knowing the area where the character is written. , will be explained in detail below according to the figures.

FIG. 1 is a diagram showing an example of a character entry frame for explaining an embodiment of the present invention, in which 1 is a character entry frame, and 2 to 5 are character entry frames in the character entry frame 1. If characters are written in the character entry areas 2 and 3, the character type is determined to be katakana. Similarly, the above character entry areas 3 and 4,
If characters are written only in 3, 5, and 3, the character types are determined to be hiragana, alphabetic characters, and numbers, respectively.

FIG. 2 is a diagram showing an example of characters written in the character entry frame, in which 6 is an example of katakana, 7 is hiragana, 8 is a number, and 9 is an alphabetic character.

FIG. 4 is a diagram showing an example of a form used in the present invention. In the figure, 30 is a form, and 31 is a string of character entry frames in which the character entry frames 1 described in FIG. 1 are arranged.

FIG. 5 is a diagram showing the configuration of the apparatus according to the present invention, and 10 indicates where in the character entry areas 2 to 5 in the entry frame 1 the character pattern input by the character pattern input means 24 is placed. This is a character entry area detection means for detecting whether or not a character is written. In addition, in the figure, the same reference numerals are attached to the same or corresponding parts as in FIG. 7.

In the above configuration, the character entry area detection means 10
Now, by comparing the position information on the form 30 of the character pattern input by the character pattern input means 24 with the position information on the form 30 of each character entry frame in the character entry frame row 31, It is detected where in the character writing areas 2 to 5 the pattern is written.

Next, the character type determination means 11 receives the information from the character entry area detection means 10, and receives the information from the character entry area 2 to
5, where the above character pattern is written, determine the character type of the above character pattern based on the above rules as explained in Fig. 2, and use recognition means 26 to 29 corresponding to the character type. Recognize the above character pattern.

FIG. 3 is a diagram for explaining in more detail the relationship between the character entry area detection means 10 and the character type determination means 11 in the configuration of the above embodiment.
15 are means for detecting whether or not characters are written in the character entry areas 2 to 5, respectively; 16 to 1;
Reference numeral 9 denotes an information line connecting the detection means 12 to 15 and the character type determination means 11, and 20 represents the determination result from the character type determination means 11.

For example, in the case of entry example 6, the detection means 12
The characters in entry example 6 above are detected in and 13,
The logical “1” on the information lines 16 and 17 is 18,1
At step 9, a logical "0" is sent as data to the character type determining means 11, where it is determined that the entry example 6 is Katakana.

With this configuration, the person writing can freely select the type of character to write in, without having to determine the type of character to be written in the reading area in advance as in the past.

In addition, although one example of the character entry frame has been explained above, the character entry frame is not limited to this, and the case where the character types are katakana, hiragana, numbers, and alphabetic characters has been explained, but it can also be used for other character types such as kanji. May be used.

Further, in the above embodiment, the text entry frame is provided on the form, but it goes without saying that the text entry frame may be provided on a tablet connected to a character reading device.

As described above, according to the present invention, the character type is determined by looking at the entry area of the same character entry frame, so the character type to be used is not restricted in advance, and the person writing the character can freely select the character type. can be filled in.

[Brief explanation of the drawing]

FIG. 1 is a diagram showing an example of a character frame shown for explaining an embodiment of the present invention, FIG. 2 is a diagram showing an example of characters written in the character frame, and FIG. FIG. 4 is a diagram for explaining the configuration of the entry area detection means of the embodiment, FIG. 4 is a diagram showing an example of a form used in the present invention, FIG. 5 is a diagram showing the configuration of the embodiment of the present invention, and FIG. 7 is a diagram showing a form used in the conventional device, and FIG. 7 is a diagram showing the configuration of the conventional device. In the figure, 1 is an example of a character frame, 6 to 9 are examples of writing in katakana, hiragana, numbers, and alphabetic characters, 10 is a character entry area detection means, and 11 is a character type determination means.
Note that the same reference numerals in the figures indicate the same or equivalent parts.
