Abstract

PURPOSE:To detect character types in accordance with entry areas of entered characters by dividing a character entry frame to plural areas and making entry areas different by character type. CONSTITUTION:A form 30 is provided with a character entry frame 1, and this character entry frame 1 is divided to plural areas, and entry areas are different by character types. A character entry area detecting means 10 compares information of the position of a character pattern, which is inputted by a character pattern input means 24, on the form 30 with information of the position of each character entry frame 1 of a character entry frame row 31 on the form 30 to detect the character entry area where the character pattern is entered. A character type discriminating means 7 receives information from the character entry area detecting means 10 to detect the character entry area where the character pattern is entered, and the means 7 discriminates the character type of the character pattern, and the character pattern is recognized by one of recognizing means 26-29 corresponding to the character type.

Description

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

Figure 6 is a diagram showing an entry form used in a conventional device of this type. Character frame C2 and character frame (C) are
They are distinguished by their coordinate positions on 1.

FIG. 7 is a diagram showing the configuration of a conventional device of this kind, and in FIG. 9, c! is a character pattern input means for inputting a character pattern for one character; 5 is a written character frame position detection means for detecting in which character frame the above character pattern is written, and συ is a means for determining the character type of the above character pattern based on the information on the position of the written character frame in which the above character pattern is written. Character type determination means.

(a) is a number recognition means, @ is a katakana recognition means, @ is a hiragana recognition means, and (a) is an alphabet recognition means.

In the above configuration, the input character frame position detection means (c) detects whether the character pattern inputted by the two-character pattern input means Q is in the same position of the one-character frame (c) and the character frame @, and the two characters When it is detected that the character pattern is written in the frame cl'l+, the character type determination means αυ determines that the character pattern is a number, and the number recognition means (a) recognizes it. As described above, in the conventional device of this building, the type of characters to be written in the character entry frame was determined in advance, so there was a drawback that the person writing could not freely select the type of characters to write.

In order to solve these drawbacks, this invention divides the two-character entry frame into multiple areas and changes the entry area for each two character types, so that the character type can be determined by knowing the entry area of the character. , 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 this invention, and in FIG. 2, 111 is a character entry frame;
(2) to (5) are the character entry areas in the above character entry frame tl+, and the 9 character types of Mizuai where characters are entered in the above character entry areas (2) and (3) are determined to be katakana. do. Similarly, the above character entry areas (3) and (4).

If characters are entered only in (3), +5), and (3), the nine character types are determined to be hiragana, alphabetic characters, and numbers, respectively.

Figure 2 is a diagram showing an example of characters written in the character entry frame above. In Figure 9, (6) is katakana, (7) is hiragana, (8) is a number, and (9) is an alphabetic character. This is an example.

FIG. 4 is a diagram showing an example of a form used in this invention. It is.

FIG. 5 is a diagram showing the configuration of the device according to the present invention, in which αC indicates that the character pattern inputted by the 9-character pattern input means (product) is ) to (5) is a character entry area detection means for detecting where the text is written. In FIG. 9, the same or equivalent parts as in FIG. 7 are given the same reference numerals.

In the above configuration, the one-character entry area detection means Ql uses the position information on the form (to) of the character pattern input by the two-character pattern input means Q4 and the form (to) for each character entry frame in the nine-character entry frame string Gυ. ) By comparing the position information on
5) Detect where it is written.

Next, in the 9 character type determination means circle, 2 character entry area detection means a1
Based on the information from , it is known where in the single character entry areas (2) to (5) the above character pattern is written, and based on the above rules as explained in FIG.

The character type of the character pattern is determined and the character pattern is recognized by the recognition means (c) to (to) corresponding to one character type.

FIG. 3 is a diagram for explaining in more detail the relationship between the one character entry area detection means α and the character type determination means aυ in the configuration of the above embodiment, and a2 to haze respectively indicate the character entry areas. The means for detecting whether or not characters are written in (2) to (5), H-Ql, are the above-mentioned detecting means Q.
It is an information line connecting 3 to Q51 and the character type determining means aυ, and co is the determination result from the character type determining means αυ.

For example, in the case of the above entry example (6), the above detection means Ul and 0
3, the characters in the entry example (6) above are detected, and the characters in the entry example (6) above are detected.
is sent as data to the character type determination means fil),
Therefore, the above entry example (6) is determined to be Katakana.

Because of this configuration, there is no need to determine the type of writing in the reading area in advance as in the past.
The person filling in the form can freely choose the font type and fill in the form.

In addition, although the above explanation describes one example of a character entry frame, the single character entry frame is not limited to this, and the two character types are katakana, hiragana, numbers, and alphabetic characters, but it can also be used for other character types such as kanji. May be used.

Further, in the above embodiment, a character entry frame is provided on the form, but it goes without saying that the character entry frame may be provided on a tablet connected to a nine-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 drawings]

FIG. 1 is a diagram showing an example of a character frame shown to explain 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 showing an example of a form used in this invention. FIG. 5 is a diagram showing the configuration of an embodiment of this invention.
