Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a handwritten numeral writing guide used as an auxiliary means for writing handwritten numerals readable by an optical character reader or the like without errors.

(Summary of the Invention) The handwritten number entry guide according to the present invention includes a rectangular entry frame written on a paper surface, a center vertical line provided vertically near the center of this entry frame, and a center vertical line at the center of the center vertical line. first to third horizontal lines provided near the upper end and lower end so as to be orthogonal to the center vertical line; a left end upper vertical line provided to connect the left end vicinity of the second horizontal line;
a diagonal line provided so as to connect the vicinity of the right end of the second horizontal line and the vicinity of the lower end of the center vertical line; a closed curve provided so as to be in contact with the third horizontal line and the left end upper vertical line; a first line provided so as to connect the vicinity of the upper left side and the vicinity of the lower right side of the closed curve; and the vicinity of the upper right side of the closed curve; A second line is provided to connect the left end of the third horizontal line, and by simply writing numbers along these horizontal lines, vertical lines, etc., no matter who writes these numbers, optical character reading is possible. This allows the device to read it without error.

(Prior Art) When inputting numerical information into a computer using an optical character reader (hereinafter referred to as OCR) that reads handwritten numbers, a form that can be handled by this OCR is usually used. Ru.

FIG. 3 is a plan view showing an example of this type of form. As shown in this figure, this form 1 has an OC at a predetermined location on its surface.
A reading area (hereinafter referred to as a field) 3 from which R is to be read is provided, and each field 3 is provided with a character frame 2 for writing handwritten numerals, one digit at a time. In order to increase the recognition rate of the numbers written in the character frame 2, that is, the reading rate when these numbers are read by OCR, the character frame 2 is set to J as shown in Figure 4.
This is a part where you are required to write standard glyphs (commonly handwritten numerals) specified by IS (Japanese Industrial Standards), and the person filling in the digits looks at this standard glyph and uses it as a model to write the numbers.

In this case, these numbers are used to distinguish them from alphabetic characters that are similar to numbers (e.g., 5 and S), kana characters that are similar to numbers (e.g., 7, wa, ri), etc. , has a different glyph shape from these characters, but field 3
If only numbers are entered in box 2, even if you write a number similar to the alphabetic character “S N” in box 2, it will be replaced with the kana character “wa”
Even if you write a number similar to ``1'', the OCR recognizes these characters as numbers, so even if you write a somewhat confusing number, the OCR will recognize it correctly. Even if the OCR side recognizes the number as a number, there is a risk that the person looking at the number may misidentify it, so it is desirable that the font be as close to a standard font as possible and be easy to write. ing.

However, in this case, it is difficult for the person writing the numbers in the standard character shape while looking at the standard character shape, and for this reason, the writing frame 2 is usually filled with colors (dropouts) that cannot be read by OCR. A writing guide is printed in color (color) so that even those who are not used to writing numbers can write numbers in a form as close to the standard glyph form as possible.

FIG. 5(a) is a plan view showing an example of such a writing guide. The entry guide 4 shown in this figure has two round marks 6.7 in the center of the entry frame 2, and the person filling in numbers uses these round marks 6.7 as a guide as shown in Fig. 5(b). Write the numbers as shown. In addition to this entry guide 4, for example, Fig. 6(a), Fig. 7(a), Fig. 8(a)
Filling guides 8, 9, and 10 as shown in Figures 8 and 9 have already been put into practical use. These entry guides 8 to 10 each have a line 11 shaped like an "8" in the center of the entry frame 2, or
A B"-shaped line 12 may be provided, or a B"-shaped line 1 may be provided.
3 and a line 14 in the shape of an ``X 11'' are overlapped, and the person filling in the information uses these lines 11 to 14 as guides to draw figures 6(b), 7(b), and 8, respectively. Fill in the necessary numbers as shown in (b).

(Problems to be solved by the invention) By the way, such conventional entry guides 4, 8 to 10,
Next, it has disadvantages as explained below.

(b) The shapes of the numbers are '1'', 42'', and '4'.

5 II, 11711, many of which have vertical or horizontal straight lines as constituent elements, but as shown in Figure 5 (a
) and a guide for filling out forms such as those shown in Figure 6(a) 4゜8
Since there is no straight line to properly guide these vertical and horizontal lines, there is a risk that the person writing the letter will write a deformed character shape that cannot be read correctly by OCR, as shown in FIG.

(b) Also, Figure 5 (a), Figure 6 (a), Figure 7 (a)
In the entry guide 4.8.9, there are no regulations regarding the length of straight lines, or even if there are, they are insufficient, so when the number "4" is handwritten, ) to (C) may be written.

(c) In addition, the entry guide 9 shown in Fig. 7 (a) and the entry guide 9 shown in Fig. 8 (
The entry guide 10 shown in a) has lines 12 composing these.
．． 13. By tracing the top of 14 and writing the numbers, you can write the numbers in the correct shape, but the 7th
In the entry guide 9 shown in Figure (a), "3'' and "5
Only the number `` can be written in the correct shape naturally without any explanation; it is not clear how to write the other numbers, and the correct way to write the letters must be explained. For example, they could not write these numbers correctly.
0 is the number “O” just by tracing on the line 13.14
Not only can you not write the number 1121ZI”
6'', ``(811, 119'') are supposed to be written in a straight line as shown in FIG.

In this way, conventional entry guides 4, 8 to 10 have many elements that are left to the judgment of the filler, such as some that are difficult to fill in due to the shape of the characters, and insufficient guidance. However, there is a strong tendency to lose confidence in the entry guides 4, 8 to 10 and write numbers ignoring these entry guides 4.8 to 10. For this reason, the conventional entry guide 4.
If the number is 8 to 10, the original purpose of the writing guide will not be achieved, and as a result, each person will tend to have a unique character shape.

Therefore, even if the numbers entered in this manner are read by OCR, the expected success rate cannot be obtained, and there is a tendency for unexpected misreading to occur.

Therefore, in order to eliminate such inconvenience, conventionally, OC
Aiming to increase the correct reading rate and reduce the misreading rate of R, each OCR user is also thoroughly training the person who fills in the OCR numbers. .8 to 10 were insufficiently guided, so it was not possible to provide concrete instruction on how to write each number, and the only way to teach students how to write them was through abstract expressions. therefore,
Even with this kind of training, it was not possible to get all participants to enter the correct numbers.

In view of the above circumstances, the present invention has been developed so that if numbers are written while following the rules for using the entry guide, OCR can correctly read them no matter who writes them, thereby increasing the rate of correct reading and reducing the rate of misreading. The purpose is to provide a handwritten digit entry guide that can significantly reduce the number of handwritten numbers.

(Means for Solving the Problems) In order to solve the above problems, the handwritten numerical entry guide according to the present invention has a rectangular entry frame written on paper and a vertical line near the center of this entry frame. A central vertical line provided in the central vertical line, first to third horizontal lines provided near the center, upper end, and lower end of the central vertical line so as to be orthogonal to the central vertical line, and these first and second horizontal lines. , a diagonal line provided to connect the vicinity of the right end of the second horizontal line and the lower end of the center vertical line; A closed curve provided so as to be in contact with the third horizontal line and the left end upper vertical line, a first line provided so as to connect the upper left side of the closed curve and the lower right side of the closed curve, and the upper right side of the navigation closed curve. and a second line provided to connect the vicinity of the left end of the third horizontal line.

(Example) FIG. 1 is a plan view showing one embodiment of the present invention.
