Abstract

PURPOSE:To change a correction operation at every document unit and to efficiently obtain document data with high reliability by controlling the correction of the document data corresponding to an identified document based on the correction operation. CONSTITUTION:A document identification part 2 identifies the kind of the docu ment from the document data 11 read at a reading part 1, and outputs identifica tion data 21 to a selection part 3. A correction system different at every kind unit of the document is stored in a memory 7 in advance, and the selection part 3 selects the correction operation corresponding to the identification data 21 from the document identification part 2, and outputs it to a correction control part 4. The correction control part 4 verifies the document data 11 based on a selected correction system 31, and outputs the document data 41 to a correc tion part 6 when correction is needed and the correction part 6 displays the document data 41 on a screen, and outputs the document data corrected and confirmed by an operator to the correction control part 4 as data 61. Thereby, the correction operation can be changed at every document unit, and reading efficiency can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical character control device, and particularly to an optical character control device that controls modification of form data read from a form.

[Conventional technology]

Conventional optical character reading devices correct the form data according to a unique preset correction method before reading the form when a reading error such as unreadable characters or misreading occurs when reading the characters written on the form. was under control.

FIGS. 2(a) to 2(c) are schematic diagrams for explaining one conventional example.

In mixed reading of forms A, B, and C, field a
When a reading error such as unreadability or misreading occurs in l+...c2, the correction operation of the form data is constant among forms A, B, and C.

In other words, when the preset correction operation is to correct the form data, when form data that requires correction such as a reading error occurs when reading forms A, B, and C, the read data is displayed on the screen. Then, the operator corrected the form data by inputting data from the keyboard.

However, when reading a plurality of types of forms in a mixed manner, the degree of reliability required for the read form data often differs for each form.

For example, when a header form and a data form are read together, the header form requires higher reliability than the data form due to the nature of its data, so the read form data is often checked and corrected by the operator.

In conventional optical character reading devices, confirmation and correction of form data is applied to both error forms and data forms that are mixedly read, so it was not possible to check and correct form data only for head forms.

[Problem to be solved by the invention]

The conventional optical character reading device described above confirms and corrects the read form data according to a correction method that is uniquely set in advance, so when reading multiple forms together, corrections are made for each identified form. Since the operation cannot be changed, the reading efficiency is poor.

[Means to solve the problem]

The optical character control device of the present invention includes means for identifying a tumor on a form from read form data, means for selecting a correction operation corresponding to the identified form, and correction of the form data based on the selected correction operation. and means for controlling.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

The reading unit 1 reads form data from a plurality of types of forms.

The form identification unit 2 reads the form data 11 read by the reading unit 1.
The type of form is identified from the information, and identification data 21 is output to the selection section 3.

The memory 7 stores in advance different correction methods for each type of form.

The selection section 3 selects from the memory 7 a correction operation corresponding to the identification data 21 from the form identification section 2, and outputs it to the correction control section 4 as data 31.

The correction control unit 4 verifies the form data 11 based on the selected correction method 31, and if correction is necessary, outputs the form data 41 to the correction unit 6, and if correction is not necessary, outputs the form data 42.
The form data is output to the output unit 5 as follows.

The correction unit 6 displays the form data 41 on the screen, controls data entry from the keyboard by the operator, and converts the form data corrected and confirmed by the operator into the data 6.
It is output to the correction control unit 4 as 1.

The modification control section 4 verifies the modified data 61 from the modification section 6 and outputs it to the output section 5 as form data 42.

The output unit 5 outputs the form data 42 to an output device such as a floppy disk.

〔Effect of the invention〕

As explained above, the optical character control device of the present invention includes means for identifying the type of form from read form data;
means for selecting a corrective action corresponding to the identified form;
By having a means for controlling correction of the read form data based on the selected correction operation, the correction operation can be changed for each form identified in mixed reading of multiple types of forms, resulting in high reliability. This has the effect that form data can be obtained efficiently.
