[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an OCR data input processing method for optically reading character data from a form by an OCR device and inputting the data, and particularly to efficiently check a logical error of the OCR data read from the form. The present invention relates to an OCR data input processing method for performing the above.

Therefore, the OCR data input program 3
After reading the form by, the user program is started and the user's own logical error check is executed. The user program 4 reads the data file 5, performs a specified logical error check on the OCR data, calls a correction screen to make a correction when an error is detected, and when the correction process ends, the correction result is the same again. The logical error check is performed, and if an error is detected, the correction is repeated, and the data resulting from the error not being detected is stored in the data file 5.

[0006]

In the conventional OCR data input processing method, the logical data check of the OCR data read from the device, which is performed by the OCR data input program, is only a general-purpose check function. . Therefore, for more complicated data check that needs to be performed by each user, after editing the OCR data by the OCR data entry program, the data is read from the data file by the original program newly created by the user, and the logical check is performed. After the error check, the data had to be displayed on the screen, corrected, and then stored in a data file. For this reason, the processing took time and the burden of creating the user program was large.

An object of the present invention is to make the OCR data check unique to the user easy by the user program so that the OCR data input process becomes efficient and the processing time is shortened.

[0008]

According to the present invention, a user program can be called from an OCR data input program, eliminating the need for data file input / output processing and screen correction processing on the user program side. Is O
This is intended to solve the problem by allowing only the logical error check of CR data to be performed.

FIG. 1 is a diagram illustrating the principle of the present invention. In FIG. 1, 1 is an OCR that reads OCR data from a form.
Device. Reference numeral 2 is a processing device for inputting OCR data.

Reference numeral 3 is an OCR data input program for controlling the input processing of the OCR data, which reads the OCR data, checks a general logic error, corrects the error on the screen, edits the OCR data, and writes the data file. Store. Reference numeral 4 is a user program for performing a user-specific logical error check on the OCR data.

Reference numeral 5 is a data file for storing OCR data which has been subjected to error checking and correction. OC
The R data input program 3 is called to the user program 4 at the end stage of each processing of reading OCR data and error correction.

In FIG. 1, the OCR data input program 3 displays a correction screen when a logic error is detected to make a correction, and calls the user program 4 again after the correction processing is completed. The user program 4 performs the logical error check as in the previous case, and returns the check result again.

When a logic error is detected, the OCR data input program 3 displays a correction screen to correct the error, and repeats the operation of calling the user program 4 until the logic error is eliminated. When no logic error is detected, the OCR data is stored in the data file 5.

[0014]

In FIG. 1, the user program 4 is an OCR.
It functions as a sub-program that only checks the logic error of the data input program 3, and there is no need to input / output or correct the data file 5. Therefore, the program scale can be reduced, and even when there are many types of forms and a large number of logical error check contents, the burden of creating the user program is small. Further, since the entire procedure of the OCR data input process is made efficient, the processing time can be shortened.

[0015]

EXAMPLES Next, examples of the present invention will be described. As shown in FIG. 2, when calling the user program 4, the OCR data input program 3 uses the notification information (described later) consisting of the character data record 6, the user definition information 7 and the auxiliary information 8 for each form. Need to hand over to the
Therefore, the address of each information is notified to the user program 4 at the time of calling.

The user program 4 refers to the character data record 6, the user definition information 7, and the auxiliary information 8 in accordance with the notified address, performs a logical error check, and if an error is detected, the character data An error state is set in the management information of the record and the OCR data input program is notified.

The character data record 6 includes management information including the version number of the data format, information indicating the status of rejection and logical error of items in the data, various ID information, and O.
It consists of CR read data. The data of one form is stored in one character data record, and the data is stored in the processing order. The user program 4 refers to predetermined data in the character data record 6 to check for a logical error. If an error is detected, the information on the item is treated as a logical error and the OCR data input program 3 indicates that there is a logical error. Notice.

The user definition information 7 is information indicating the position of an item existing in the character data record 6, and is a field position indicating the data position of the item in field units and field user information in item units. Including and
The auxiliary information 8 is auxiliary information that accompanies the calling of the user program 4, and the processing stage in the OCR data input program 3 when the user program 4 is called from the OCR data input program 3 is immediately after reading the OCR device. Whether it is present or just after the correction screen is processed, and whether it is a batch reading or a batch correction is indicated.

Feed it to the reading section. (B): The reading unit reads the OCR data. (C): The user program is started and the user's own logical error check is performed. (D): When a logic error is detected, OC is displayed on the correction screen.
Modify R data. (E): Examine whether there is a reject error, and if there is, (l)
Otherwise, (f) is executed. (F): Whether or not to perform a general-purpose logical error check is discriminated according to an instruction. When it is performed, (g) is executed, and when not performed, (h) is executed. (G) The presence / absence of an error in a general-purpose logical error check is determined, and if there is, (m) is executed, and if not, (h) is executed. (H): The user program is started and the user's own logical error check is performed. (I): It is determined whether or not there is a logic error, and if there is, (n),
If there is not, execute (j). (J): Store the OCR data in the data file. (K): If the hopper of the OCR device is not empty, return to (a) to continue reading the next form, and if the hopper is empty, end it. (L): If there is a reject error in (e),
It is determined whether the forced storage is instructed. If the forced storage is performed, the error OCR data is stored in (j), and if the forced storage is not performed, the reject error is corrected in (d). (M): If there is a logic error in (g), (l)
Similarly to (1), (j) or (d) is executed depending on whether to forcibly store. (N): If there is a logic error in (i),
Similar to (l) and (m), (j) or (d) is executed depending on whether or not forced storage is performed.

[0020]

As described above, according to the present invention, a user can check a unique arbitrary detailed logical error by creating only a program having a function of checking a logical error of OCR data. Even if an error is detected, it can be easily corrected on the correction screen of the conventional OCR data input program. And as a result, O
All error checks can be performed in a series of flow from reading CR data to correction and data storage, and the processing time until correct OCR data is obtained can be shortened.
