Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input method and an apparatus therefor.

[0002]

2. Description of the Related Art Conventionally, documents such as invoices issued by medical institutions, school cram tables, and automobile tax statements (hereinafter referred to as "original data")
The data such as individual number, date of birth, date of entry, score, amount of money, number of times, etc. are entered in the above), and in order to manage these data with a computer, the necessary data in these original materials must be entered. The operator obtains the digitized data by inputting through the keyboard of the data input device while seeing with his own eyes. In this case, the data to be input (the data to be input by the keyboard among the data described in the above-mentioned original data) is different for each source material, and therefore, according to the data to be input,
An input screen is created for each source material.

In order to improve the reliability of the input data, after one operator inputs a predetermined source material, another operator inputs the same source material, and the input data by the two operators is different. If so, an alarm will sound when you enter different data,
A second operator (an operator who is proficient in data input work) re-inputs and treats the re-inputted data as correct input data. That is, the input data is determined by the re-input data.

[0004]

However, in the above-mentioned conventional example, there is a problem that much labor is required for the input work because two operators are always performing the input work for one original material. . However, if one operator carries out the input work only once for one source material, the labor required for the input work can be reduced, but the reliability of the input data decreases. The problem arises. That is, in the above-mentioned conventional example, there is a problem that it is not possible to meet the demand for reducing the labor required for the data input work while maintaining the reliability of the input data at a predetermined level.

A first object of the present invention is to provide a data input method and apparatus capable of reducing the labor required for data input work while maintaining the reliability of input data at a predetermined level.

Further, in the above-mentioned conventional example, since the verification is performed with the same labor as that at the time of the first input, there is a problem that the efficiency of the verification operation in the data input is low. For example, even if the accuracy of the data input by the first operator is 99% or more, in this case, the same effort as that at the first input is spent to correct the erroneous input data of 1% or less. However, the efficiency of verification work is low and the labor cost is high.

On the other hand, it may be considered that a character in the original material is recognized by OCR and the recognized digitized data is used as input data. However, in this case, at least the recognition rate of OCR has not reached 100% at present, and the recognition rate is lower for handwritten Chinese characters, and unrecognizable characters and characters that are not confident in recognition must be corrected by humans. You will need it. If you make this fix,
For unrecognizable characters and characters that are not confident in recognition, it is necessary to search for the relevant part from the original material and manually input with a keyboard, etc. On the other hand, even for data that can be recognized by OCR, the input data is highly reliable. It requires manual scrutiny to maintain sex. For this reason, when the OCR is used as described above, there is a problem in that the data input work is slowed down, that is, the efficiency of the verification work in the data input becomes low. That is, in the method of checking the digitized data recognized by the OCR one by one as described above, there is a problem that the efficiency of the verifying operation in the data input becomes low.

A second object of the present invention is to provide a data input method and an apparatus therefor capable of improving the efficiency of the verification work in data input.

Further, in the above-mentioned conventional example, since the data is input at the place where the data input device is installed, the original material is brought to the place where the data input device is installed, and it is described in the original material. However, there is a problem in that it may not be possible to maintain the security of the data described in the original material that does not need to be input because the data that has already been input and that does not need to be input is also carried in.

A third object of the present invention is to provide a data input method and apparatus capable of maintaining security for data described in the original material and which does not need to be input.

Further, in the above-mentioned conventional example, there is a large amount of description that does not need to be input in the original material, and it is necessary for the operator to judge which description content is necessary for data input each time data is input. Therefore, the efficiency of data entry work is low, especially for less skilled operators.
There is a problem that the efficiency of data input is low.

A fourth object of the present invention is to provide a data input method and a device therefor, which are highly efficient in data input work.

[0013]

According to the present invention, an original material in which characters such as characters or numbers are written is read by an image reader, an image read by the image reader is recorded by a printer, and the printer prints the image. The operator visually recognizes the character from the recorded paper, the operator inputs a keyboard for the visually recognized character, while the character recognition device recognizes the character based on the image read by the image reader, and the character recognition device recognizes the character. The electronic data and the electronic data output from the keyboard are collated, and a warning is issued when the electronic data output from the character recognition device and the electronic data output from the keyboard do not match,
After this warning, the operator inputs the keyboard again and confirms the re-inputted digitized data as the input data.

[0014]

According to the present invention, an original material on which characters are written is read by an image reader, and among the images read by the image reader, only an image necessary for data input is recorded by a printer and printed by the printer. The operator visually recognizes the character from the recording paper, and the operator inputs a keyboard for the visually recognized character.
The character recognition device is caused to recognize the character based on the image read by the image reader, and the digitized data of the character recognized by the character recognition device is collated with the digitized data output from the keyboard, and output from the character recognition device. A warning is issued when the digitized data output from the keyboard and the digitized data output from the keyboard do not match, and after this warning, the operator again inputs the keyboard, and this re-inputted digitized data is confirmed as the input data.
Since only one operator is required, the efficiency of data input and verification operations can be improved.
Since only the image necessary for data input among the images read by the image reader is recorded by the printer, it is possible to maintain the security of the data described in the original material that does not need to be input.

1 is a block diagram of a data input device 1 according to a first embodiment of the present invention.

In this embodiment, an image reader 20 for reading an original material 10 in which characters such as characters, numbers, symbols are written, and an image data storage device 30 for temporarily storing the image data read by the image reader 20. And a character recognition device 40 for recognizing a character based on the image read by the image reader 20 and outputting digitized data corresponding to the recognized character, a keyboard 50, a data collation and confirmation means 60.
A warning device 61 and a character data storage device 70 are provided.

The character recognition device 40 is a device for recognizing a character.
It may be at least one of Hiragana, English letters, Kanji, numbers and symbols. Further, foreign characters other than English characters may be included in the characters, that is, the character recognition device 40 also recognizes foreign characters other than English characters, and digitizes the recognized characters. The data may be output. Further, as the character recognition device 40, an OCR equipped with an image reader may be used.

The keyboard 50 is a keyboard on which an operator inputs characters in the original material 10 and outputs digitized data corresponding to the input characters. The warning device 61 uses the keyboard 50 and the digitized data corresponding to the character recognized by the character recognition device 40.
This is a device that warns when there is a mismatch with the digitized data input from. The data collating / determining means 60 collates the digitized data of the character recognized by the character recognition device 40 with the digitized data input from the keyboard 50, and again, from the keyboard 50 after the warning about the character corresponding to the mismatched portion. It is a means for confirming the input digitized data as input data. Further, the data collating and confirming means 60 confirms, as the input data, the computerized data in which the computerized data of the character recognized by the character recognition device 40 and the computerized data input from the keyboard 50 are matched. The character data storage device 70 includes a data collating / determining means 60.
Is a device for storing the input data determined by.
Instead of connecting the data collation / confirmation device 60 to the character data storage device 70, it may be connected to a host computer (not shown).

Next, the operation of the above embodiment will be described.

FIG. 2 shows the original material 10 used in the above embodiment.
It is a figure which shows an example.

The original document 10 includes the municipality number [#
1], beneficiary number [# 2], symbol / number of insured card [# 3], name [# 4], date of birth [# 5], name of injury or illness [# 6], start date of medical treatment [# 7], ..., Total points claimed [# 19], Total points determined [# 20],
Partial contribution outside the hospital [# 21], Partial contribution outside the hospital [#
22], and other data. Of these, the data to be input in the above embodiment is the data entered in the column in which [# + number] is entered, and the number in [# + number] described in FIG. It is a serial number of the image data shown in FIG.

First, the original material 10 is read by the image reader 20 one by one, the image data read by the image reader 20 is stored in the image data storage device 30 such as a magneto-optical disk, and the image reader 20 reads the image data. The character recognition device 40 is caused to recognize the character based on the image. In this case, the reading by the image reader 20 is performed during the daytime, and the character recognition by the character recognition device 40 is collectively performed during the nighttime. For reading by the image reader 20, it is necessary to insert the original material 10 into the image reader 30 one by one, but the processing time for one original material 10 is relatively short, and the character recognition device 4
Although the character recognition by 0 requires a long processing time for one sheet of the original material 10, even if a large number of characters are recognized, one set for character recognition is sufficient.

On the other hand, the operator looks at the original material 10 and visually recognizes the character described in the original material 10, and the operator inputs the visually recognized character from the keyboard 50. In this case, a certain original material 10 is read by the image reader 20 and the character recognition device 40 is used.
After the recognition by the above is completed, the operator inputs the same original material 10 by the keyboard.

In parallel with the keyboard input by the operator, the data collating / determining device 60 collates the digitized data output from the character recognition device 40 with the digitized data output from the keyboard 50 for the same original material 10. If the two digitized data match each other, the data is confirmed as the input data, and the digitized data is output to the character data storage device 70. Original document 10
If the data to be input (that is, the data to be input by the keyboard 50) among the data described in (1) is clearly written, the recognition rate of the character recognition device 40 is high, and in some cases, the character recognition device 40. The recognition rate may be 100%, and at this time, it is only necessary to input data from the keyboard 50 and it is not necessary to correct the data recognized by the character recognition device 40. Thus, the higher the recognition rate of the character recognition device 40, the less the work of the operator is required, and the efficiency of the verification work in the data input is improved.

In the past, two operators used the keyboard to perform data input work, but in the above embodiment, only one operator is required to perform data input work. Operation of the reader 20,
The labor required to operate the character recognition device 40 is very small, and therefore, the above embodiment requires almost half the labor cost of the conventional example.

On the other hand, if both digitized data for the same character do not match, the warning device 61 gives a warning.
For example, if a chime is used as the warning device 61,
When they do not match, a sound like "ping-pong" is generated to warn. If the two digitized data do not match, a warning is issued almost at the same time when a predetermined character is input from the keyboard 50. Therefore, the operator again inputs the character corresponding to this warning from the keyboard 50, and the electronic characters input after the warning are input. The digitized data is confirmed as input data, and the digitized data is output to the character data storage device 70.

A display not shown (display such as LCD, CRT, lamp, etc.) is provided in the vicinity of the keyboard 50, the character input from the keyboard 50 is displayed on the display, and the warning device 61 and the display are connected to each other to display the warning device. When the warning is issued by 61, the non-coincidence portion is clearly indicated (warning) in the character displayed on the display device by underlining, coloring, frame enclosing, etc. After this warning, the underlining portion is overstruck and The data corresponding to the hit character may be the confirmed input data. By doing so, data correction work (re-input work) becomes easy.

According to the above embodiment, when the digitized data outputted by the character recognition device 40 and the digitized data outputted by the operator are determined as the input data, and both the digitized data do not match. , The data entered by the operator after being warned of the inconsistency is confirmed as the input data. Therefore, the accuracy of the input data can be maintained as before, and moreover, only one person can use the given source material. Since the input work and the verification work are completed only by the operator of, the efficiency of the input work and the verification work in the data input is high, and the labor cost can be significantly reduced.

Further, comparing the method in which the character recognized by the OCR is checked one by one with the above embodiment, in the above embodiment, when the character recognition device 40 erroneously recognizes the character, a warning is issued at the same time as the keyboard input by the operator. Therefore, it is not necessary to search for the corresponding portion of the unrecognized character of the character recognition device 40 or the character which is not confident in recognition from the source material 10, while the digitized data output by the character recognition device 40 and the keyboard input of the operator are used. Since the data that matches the digitized data is determined as the input data, the data that can be recognized by the character recognition device 40 does not require manual scrutiny, and in this sense as well, in the above-described embodiment, the data input verification is performed. High work efficiency.

In the above embodiment, the image reader 2
The reading by 0 is executed in the daytime which requires manpower,
Character recognition by the character recognition device 40 that does not require human hands can be collectively executed at night, that is, batch processing can be performed. In this way, the image reader 2 can be used.
Regarding the image data that has been read by 0,
It is possible to input a large amount of data as compared with the online processing in which the character recognition device 40 immediately recognizes the character.

Further, the warning device 61 also gives a warning when the character recognition device 40 cannot recognize the character, so that the operator can carefully watch the difficult-to-read character at the time of keyboard input, and the rate of erroneous input is low. Become.

It should be noted that the image data storage device 30 may be omitted and processing may be performed by the above-mentioned online method.
Even in this case, the efficiency of the input work and the verification work in the data input is high, and the labor cost can be significantly reduced.

When the digitized data output from the character recognition device 40 and the digitized data output from the keyboard 50 do not match for the same character, the digitized data output from the character recognition device 40 You may make it display together with the digitized data output from the keyboard 50. This makes the mismatched portion clear and facilitates data correction work (re-input work).

FIG. 3 is a block diagram of the data input device 2 according to the second embodiment of the present invention.

The data input device 2 is basically the same as the data input device 1, but the image data stored in the image data storage device 30 is printed by the printer 31, and the printed recording paper 32 is printed. Is different from the data input device 1 in that the operator inputs data while watching.

That is, in the data input device 2, the image read by the image reader 20 is printed by the printer 31, the character required by the operator is read from the printed recording paper 32, and the operator reads the read character by the keyboard 50. This is what you type in.
Subsequent processing is the same as that of the data input device 1.

In the data input device 2, the main body of the data input device 2 (from the data input device to the image reader 20,
It is not necessary to take out the original material 10 itself to the place where the image data storage device 30 is installed). That is, the image reader 2 is stored in the storage place of the original material 10.
0 and the image data storage device 30 are carried in, the original material 10 is read there, and the image data storage device 30 is brought back to the installation location of the character recognition device 40, there is no possibility of the original material 10 being lost due to being taken out. .

It should be noted that instead of connecting the printer 31 to the image data storage device 30, the printer 31 is connected to the image reader 20, and the image reader 20 is connected to the original document 10.
The printer 31 may immediately print the image data obtained by reading.

FIG. 4 is a block diagram of the data input device 3 according to the third embodiment of the present invention.

This data input device 3 is basically the same as the data input device 2, but of the image data stored in the image data storage device 30, only the characters that the operator should input on the keyboard are selected. The difference from the data input device 2 is that an image data processing device 33 that processes image data so that the printer 34 prints is provided. As an example in which the printer 34 prints only the characters that the operator should input using the keyboard, it is conceivable to mask unnecessary data and print only the necessary data.

FIG. 5 is a diagram showing an example of keyboard input data recorded on the recording paper 35 in the data input device 3 shown in FIG. 4, and not only is unnecessary data masked but also necessary. The data is organized and rearranged.

That is, on the recording paper 35, the characters to be inputted by the operator from the keyboard are printed on one paper for the plurality of original materials 10. In FIG. 2, only one original material 10 is shown as an example, the number of the original material is “0001”, and the characters (characters, numbers, symbols, etc.) to be input by the keyboard are # 1 to # 1. # 2
There are 22 of 2 and the source number is "0002",
Also for "0003", ..., 22 characters to be input are described, and image data of these characters to be input are arranged in a horizontal row for each original material 10, and a large number of original materials 10 are arranged. , The image data of the character to be input is aligned.

When the operator inputs a keyboard, the operator inputs it while looking at the recording paper 35. Since only the image data to be input by the keyboard is arranged on the recording paper 35, an unnecessary image can be seen. Well, for this reason, it is efficient and error-free. In addition, multiple original documents 1
Since the data to be input of 0 is recorded on one sheet, it is not necessary to turn the page for each original material, and the operability is excellent.

In the data input device 3, there is no need to bring the original material to the place where the main body of the data input device is installed, and therefore the data described in the original material 10 that does not need to be input. Can maintain security. Further, in the data input device 3, since the description that does not need to be input in the original material is cut, it is not necessary to judge which description content is necessary for data input each time data is input, The efficiency of the input work is high, and especially, the data input becomes easy even for an operator with low skill.

The printer 34 of the data input device 3
However, the image data may be printed, and the character recognized by the character recognition device 40 corresponding to this image data may be printed together.

FIG. 6 is a block diagram of the data input device 4 according to the fourth embodiment of the present invention.

The data input device 4 causes the display 36 to display the image data stored in the image data storage device 30 in the data input device 1, and the operator can visually recognize the displayed image data from the keyboard 50. It is something to enter. The other points are the same as those of the data input device 1.

In this case, only the image data to be input by the keyboard may be displayed on the display 36. Further, as shown in FIG. 5, only the image data to be input by the keyboard is rearranged and a large number of original data are arranged. Image data of the material 10 may be displayed on the display 36.

In each of the above embodiments, the source material 10 is an invoice issued by a medical institution, a cram school score list, and an automobile tax statement, but other documents may be used as the source material 10. .
