Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form reading system using an OCR and a computer system.

[0002]

2. Description of the Related Art Conventionally, an optical character reader (OCR) has been used in various fields to optically read various forms and input character data recorded on the forms into a computer system. The record information on the form read by the OCR is input to the computer system to perform various types of information processing.

The form has a format (recording form) set according to the purpose of use, and is a form of various slips or cards. On the form, for example, a frame that is an area for recording (filling) necessary items for each of a plurality of items is printed. Characters such as numbers corresponding to each item will be entered in this frame. For example, in a company or the like, in the case of a form that is an employee card for managing the personnel of employees, items to be recorded include, for example, the employee number and the date of joining the company.

The computer system inputs the data on the form read by the OCR, that is, the read data such as the employee number and the date of joining the company, and edits the data according to a predetermined form read data process. Then, a process for creating a database according to the purpose of use is executed.

In the form reading system as described above,
It is necessary to check whether or not the data on the form read by the OCR is normal data (clean data), and if it is erroneous data, correct it to clean data.

As a specific example, in the case of the data such as the employee number and the date of joining the company, the normal data to be entered are all numbers. In this case, if characters such as alphabets are mistakenly mixed, the incorrect data will be checked.

[0007] Normally, the system displays a correction input screen on the screen of the display device based on the check result, inputs normal data in place of erroneous data, and corrects the clean data. In order to execute the correction processing including such check processing, the system prepares a correction processing program in advance.

[0008]

A conventional form reading system using OCR checks the form data read by the OCR by a correction processing program prepared in advance, and corrects the data to correct data. There is.

The contents of the form to be read differ depending on the purpose of use. Therefore, on the system side, it is necessary to prepare a correction processing program for each form, and if the form used is changed, the correction processing program corresponding to the form will also be changed. Furthermore, if a new form to be read is added, it is necessary to add a correction processing program corresponding to the form.

Therefore, conventionally, the work and cost for preparing, changing, and adding a correction processing program according to the type, change, and addition of a form have increased, and the work efficiency associated with the maintenance and operation of the system has increased. It is a factor that causes a decrease and an increase in cost.

An object of the present invention is to improve the efficiency of work for maintenance and operation of the system and cost reduction in the form reading system using OCR, particularly by improving the efficiency of the check processing of the form data. It is to be realized.

[0012]

The present invention is a form reading system constructed by using an OCR and a computer system, and is defined for each item in addition to item data corresponding to a preset item. Use a form in which item check data is recorded.

The system includes a data processing means for executing predetermined form data processing based on the item data output from the OCR means and a data check processing means for executing predetermined check processing of the item data based on the item check data. Have.

The data check processing means checks, based on the item check data, whether or not the item data has a data content that matches the predefined content. Item check data is, for example, the character type of the corresponding item data,
This is data that specifies the number of digits, or the range of numbers used in the case of date, etc.

According to the item check data, the data check processing means determines that the read data, which is read as the item data of the date, includes incorrect numbers or characters as the date, and the data is erroneous. Then, the check result is output.

According to such a system, even when the form is changed, it is not necessary to change the correction processing program by using the preset item check data. Further, when a new form is added as a reading target, only the item check data relating to the new item data is added to the item data of the form, and it is not necessary to create a new correction processing program.

FIG. 1 is a block diagram showing a configuration of a form reading system related to the first embodiment, FIG. 2 is a block diagram showing a configuration of a read data check unit used in the system of the present embodiment, and FIG. FIG. 4 is a conceptual diagram showing the format of the form of this embodiment, and FIG. 4 is a flow chart for explaining the operation of this embodiment. (System Configuration) In this embodiment, as shown in FIG.
It is assumed that the form reading system is composed of the CR 1 and the computer system, and the computer system side constitutes the reading data processing system 2.

The OCR 1 optically scans the form data recorded on the form 3 to be read, executes character recognition processing, and outputs read data corresponding to the form data to the system 2 for optical character reading. It is a device.

The OCR 1 is a read data check unit 10 for checking read data obtained by the read processing.
Having. The form 3 of this embodiment records the item check data CD set for each item together with the item data RD corresponding to the item set according to the purpose of use.

The item check data CD is composed of a code data string indicating the check contents (check pattern) set for each item data RD defined in advance. The item check data CD is composed of a code string of alphanumeric characters or symbols having a high recognition rate in the character recognition processing of OCR1 and is printed at a predetermined position on the form 3.

Specifically, as shown in FIG. 3, for example, I
The item data RD1 of the D number is set to the item check data CD of "01", and the item data RD2 of the employee number is set to the item check data CD of "50". Similarly, the item check data CD of "62" is set in the item data RD3 of the organization number.

The read data processing system 2 includes a read data input section 4, a read data storage section 5, an item check data storage section 6, a read data correction section 7, a data display / input section 8, and normal data ( Storage unit 9 for clean data).

The read data input unit 4 inputs the read data (RD, CD) output from the OCR 1, and the read data check unit 20 performs a check process as necessary. The read data storage unit 5 is, for example, a disk storage device that stores the item data RD input by the read data input unit 4 with check error information, which is the check processing result, if any.

The item check data storage unit 6 is, for example, a disk storage device that stores the item check data CD input by the read data input unit 4. The read data correction unit 7 extracts the read data from the read data storage unit 5 and creates a correction input screen based on the read data,
It is displayed on the display screen of the data display / input unit 8.

The data display / input unit 8 is specifically composed of a display device and a key input device (including a mouse), and the key input is performed in accordance with the correction input screen displayed on the display screen of the display device. It has a function of inputting correction data from the device.

The read data correction unit 7 causes the read data check unit 30 to check the correction data input from the data display / input unit 8. The read data correction unit 7 stores the clean data determined to be normal data in the normal data storage unit 9 by the check processing of the read data check unit 30.

The normal data storage unit 9 is composed of a data storage unit 9a and an external data storage unit 9b for use in predetermined data processing inside the system. The external data storage unit 9b is a buffer memory for outputting to a printing device outside the system, for example.

The computer system includes a data storage unit 9.
The normal data of the form data stored in a is used to execute predetermined data processing such as predetermined editing processing and database creation processing. (Configuration of Read Data Check Unit) The read data check units 10, 20, and 30 have the same basic configuration.
As shown in FIG. 2, a plurality of check modules (check processing programs 1 to n) 3 for each item check data 3
00.

Module control section (program)
100 activates the check module 300 corresponding to the input item check data. The module control unit 100 checks the check pattern information 200 for checking whether the corresponding item data is normal.
From, the information necessary for the check processing of the selected check module 300 is given.

The module control section 100 uses the item data RD1 as the item check data CD, for example.
When the code string “01” corresponding to is input, for example, the check module 1 is activated based on the check pattern information 200.

The check module 1 checks whether or not the data string of the item data RD1 of the ID number is normal based on the check pattern information 200 prepared in advance. For example, if an alphanumeric character that is not used in the ID number is entered as the item data RD1, that character is output as check error information. (Operation of First Embodiment) The operation of this embodiment will be described below with reference to the flowchart of FIG.

In this embodiment, as shown in FIG. 3, it is assumed that the form 3 in which the item check data CD is printed independently for each item data RD1 to RD3 is used.

The OCR1 scans the set form 3 and records (fills or prints) the item data RD1.
~ RD3 and item check data CD are read and output to the system 2 (steps S1 and S2).

The OCR 1 executes the check processing of the item data RD1 to RD3, which has been subjected to the recognition processing based on the item check data CD, by the read data check unit 10, and adds the check result to the read data.

The read data input section 4 of the system 2 is an OC
Read data (RD1 to RD3, CD) from R1 is input, and the read data check unit 20 executes a check process (steps S3 and S4).

The read data input unit 4 adds item data RD1 to RD3 and check error information, which is the result of the check process, to the read data input unit 4 and stores them in the read data storage unit 5. Further, the item check data CD is stored in the item check data storage unit 6 (step S5).

The read data correction unit 7 takes out the item data RD1 to RD3 from the read data storage unit 5, creates a correction input screen for the form data, and displays it on the display screen of the data display / input unit 8 (display device). (Step S6).

Here, the correction input screen includes the check result by the read data check unit 20. For example,
In the form 3 shown in FIG. 3, in the item data RD1,
When an alphanumeric character that is not used as the ID number is included, the correction input screen includes information indicating that the character is a check error.

If there is data to be corrected in the input form data (RD1 to RD3) from the correction input screen on the display screen, the user operates the key input device of the data display / input unit 8 to input. Yes (step S8).

The read data correction unit 7 checks the data input from the data display / input unit 8 by the read data check unit 10 based on the item check data CD stored in the item check data storage unit 6. (Step S9).

Here, the read data correction section 7 displays the correction input screen again if a check error occurs in the check processing. The read data correction unit 7 cleans the check data, that is, normal item data RD1.
The form data composed of RD3 is stored in the data storage unit 9a (step S10). Similarly, the clean data is stored in the external data storage unit 9b.

The computer system includes a data storage unit 9.
The form data stored in a is taken out, and predetermined data processing such as editing processing and database creation processing is executed. As described above, according to the present embodiment, based on the item check data CD pre-recorded on the form 3, the OCR 1, the read data input unit 4 of the system 2, and the read data correction unit 7 each receive the item data RD1. ~ It is checked whether RD3 is normal, and if there is a check error, the check result is output.

According to such a check processing method, by preparing the item check data CD for each item data and the check module corresponding thereto in advance, when the item of the form 3 is changed, the item is previously changed. As long as it is prepared, it is not necessary to change the data or program necessary for the check processing.

Further, even if a new item is required due to the change of the form, only the item check data CD and the check module corresponding thereto are added, and it is not necessary to create the entire program. Even when adding a new form to be read, is it not necessary to add the data or program necessary for the check processing, as in the above case?
Or only partial addition is required.

In the present embodiment, the item check data CD is described as a code string of numbers, but the present invention is not limited to this and may be a mark or a symbol such as a bar code. However, it is desirable that the character recognition processing of OCR1 has a high recognition rate. (Second Embodiment) As an application form of the first embodiment,
The second embodiment is a format in which the item check data to be recorded on the form 3 is added to the item data and recorded as a part of the item data string.

That is, as shown in FIG. 5, when the item data corresponding to each item of the form ID number, employee number, and date of employment is recorded, the lowest digit of each item data string is used. Item check data CD1 to CD3.

In the item check data CD1 to CD3, the number "0" means no check, the number "1" means check of the number type (0 to 9), and the number "2".
Is assumed to mean a calendar check. As a matter of course, the check contents are set in advance for other numbers as well.

Here, the number "0" not checked means
It means that the check process is not executed. Further, the calendar check of the number "2" is a process of checking whether or not a number or the like that is impossible on the calendar is recorded.
For example, if the current time is 1995, it is checked whether or not the upper two digits “75” in the item data of the joining date is normal data. In this example, it is normal, but in the case of "97", for example, a check error occurs as incorrect data.

In the case of the recording format as in the second embodiment, it is not necessary to provide an independent recording area for item check data (see FIG. 3) on the form 3, so that there is a restriction on the form layout design. Can be alleviated.

Although the item check data is naturally added to the least significant digit of the item data string in the above description, it may be the most significant digit. Further, not only one digit but also lower or upper several digits may be used as the item check data. (Third Embodiment) The third embodiment has contents corresponding to the applied form of the second embodiment, in which the item check data included in the item data string includes field lengths other than the original check processing. It is a recording format that includes additional data of.

Specifically, as shown in FIG. 6, the form ID
In the field (recording area) of each item data of number and employee number, item check data CD1, CD2 and other additional data L1, L2, P1, P2 are recorded by adding to the least significant digit of each item data. ing.

The additional data L1 and L2 are field length data that means the character length (number of digits) of the item data of the corresponding field. In this example, the additional data L
1 indicates the character length "3", and the additional data L2 indicates the character length "7".

The additional data P1 and P2 are coordinate data indicating the screen display coordinates when the read data correction section 7 displays the correction input screen in the above-mentioned system.

That is, the read data correction unit 7 takes out the additional data P1 and P2 together with the item check data from the item check data storage unit 6 when creating the correction input screen, and the item data (here, the form ID number and employee Member number)
Set the screen coordinates of.

Here, the additional data P1 (0110)
Indicates that the display start position of the form ID number is 1 in the first line on the screen.
It means the 0th digit. In addition, the additional data P2 (021
0) means that the display start position of the employee number is the 10th digit of the second line on the screen.

As a result, the read data correction section 7 is set in FIG.
As shown in, the form ID number of 3 characters is displayed from the 10th digit of the first line on the screen, and the employee number of 7 characters is displayed from the 10th digit of the second line on the screen.

As described above, according to the third embodiment, the read data correction unit 7 makes a correction input by the recording format in which the item check data and the additional data indicating the field length and the screen coordinates are included in the item data string. Screen creation process,
It can be automatically performed based on the additional data.

Of course, the additional data can be used not only as the field length and screen coordinates but also as data meaning various purposes. Further, as a common element not only in the third embodiment but also in the first and second embodiments described above, the case where a numeral is used for item check data has been described, but of course, alphabets, symbols, marks, etc. It may be data.
