Abstract

PURPOSE:To improve the overall efficiency of character reading processing by filling up directly a character set character required as format control information on a form for character setting. CONSTITUTION:In order to designate a reading area for character setting to the form 20 for character set, a line number is filled in a character frame 22a and a filed number is filled in a character frame 23a and further, a desired character set character is filled in a character frame 24a. This form 20 is read by an OCR10 and the OCR10 outputs the result of reading to an OCR controller 11. The controller 11 detects an ID number 21 based on the result of reading from the OCR10, processing character setting. That is, the character set data are edited and outputted to a memory 12 based on a character group filled in the character frames 22a-24a. Then, the character set data is fed to an output device 13 and a character set character pattern is outputted to a display device or the like.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an optical character reading device - [Technical Background of the Invention and Problems Therewith] Generally, in an optical character reading device (hereinafter referred to as OCR), Designation of read character types (hereinafter referred to as character set), which is performed to improve reading speed and reading accuracy, is given in advance as format control information.

Conventionally, the method of character setting is 1. For example, as shown in Figure 1, numbers (128 types) are recognized characters (128 types).
0 to 9), alphabetic characters (p, -z), kana characters, and symbols (ko, ?, etc.) are printed on the form 1. This form 1 contains an I which indicates that it is a character set form.
A character frame 2a in which the D number 2 is written and a character frame 3a corresponding to the recognized character are provided 1, and when character setting is performed, a predetermined character 3, that is, a set character, is provided in the character frame 3a corresponding to the character. You will need to enter the characters that mean .

Character set processing is performed by reading the form 1 filled out in this manner by the OCR. However, in the conventional method, OCR for reading kanji
Since the number of logarithmic characters to be read ranges into the thousands, a form in which all of the thousands of characters to be read are printed is used, which requires a large amount of character set processing time.

Furthermore, since there are many characters to be read, there is also the drawback that the number of sheets for character setting increases.

[Purpose of the invention]

This invention was made in view of the above circumstances, and even in the case of OCR for reading kanji, it is possible to improve the efficiency of the entire character reading process by reducing the number of forms for character setting and the processing time for character setting. The purpose is to provide a reading device.

[Summary of the invention]

The present invention uses a character set form in which line numbers, field numbers, character set characters, and control characters for specifying character set characters necessary as format control information are directly written in a character frame provided in advance. Various information entered in this form is OC
The character set data is read by R, and the control means edits the character set data based on the reading result. The character set data output from the control means is stored in the storage device as format control information. As a result, even in the case of OCR for reading thousands of kanji characters, it is unnecessary to prepare a form on which thousands of characters to be read are printed, and character set processing can be performed in less processing time. 7. [Embodiment of the Invention] An embodiment of the invention will be described below with particular reference to the drawings. FIG. 2 shows a block diagram according to this invention.
1θ reads various characters written on the character set form (20 in FIG. 3) using an optical character reading device (hereinafter referred to as OCR). The OCR control device 11 edits and outputs character set data based on the reading result of 0CR10. Reference numeral 12 denotes an external storage device (memory) that stores character set data output from the OCR control device 11 as format control information. Output device 13
outputs the character/mother turn according to the character set data.

Further, in the present invention, a character set form (hereinafter simply referred to as a form) 20 as shown in FIG. 3 is used. This form 20 includes a character frame 21a in which an ID number 21 indicating that it is a character set form is entered, a character frame 22 for entering line numbers, and a character frame 23 for entering field numbers.
h and a character frame 24a for entering a character set are provided. These character frames 21a to 24a are usually printed in dropout colors.

It is assumed that ID number 2 has been printed in advance.

The operation of this configuration will be explained. No trenches,
In order to designate the reading area for performing character setting on the form 20, a line number is written in the character box 22a, and a field number is written in the character box 23a. In this case, the line number is the line number designated for reading of the form to be read (that is, the form that is normally used), and the field number is the number specifying the field in the specified line. Furthermore, a desired character set character is written in the character frame 24a. Specifically, the information is entered as shown in FIG. 4, for example. In this case, the line number is "1" and the field number is "2", so the second line of the first line of the form to be read is
The character set for the field is done. Then, character set characters are directly written in the character frame 24a, and at this time, the character type is designated by, for example, character set control characters 25 and 26. These control characters 25 and 26 cause the characters written between them (numbers in this example) to be set to character 7.
Furthermore, for example, when characters such as "Cho, Me, Ban, Ji, Go, No, -1" are written directly in the character frame 24a, each character is set as a character.

The form 20 filled out in this way is shown in FIG.
Read by CRIO. 0CRI 0 outputs the reading result to the OCR control device 11.

Based on the results, TD number 2 is detected and character set processing is performed. That is, character set data is edited based on the character group written in the character frames 22a to 24a on the form 20 and output to the memory 12. The memory 12 stores character set data from the OCR control device 11 as format control information. The character set data is sent to the output device 13, and the character set characters are displayed on the display device, etc. This will output a turn.

In this way, character set characters necessary for reading Chinese characters, etc. are written on the character set form 20, and this form 20 is read by the 0CRIO. E, O
Based on the character set character group entered in the form 20 by the character set processing of the CR control device 11,
Character set data is edited and stored in memory 12 as format control information.

Therefore, for example, when a character set is performed based on the character set characters shown in FIG. The OCR performs a reading process assuming that the characters ``-'' are written.

〔Effect of the invention〕

As detailed above, according to the present invention, the character cent character required as format control information is directly entered in the character set form 1, thereby:
The character set data for reading kanji can be easily created, and the reading operation of OCR for reading kanji can be reliably realized. Therefore, even in the case of 0Crt for reading kanji, which has several thousand types of characters to read, it is possible to significantly reduce the number of sheets for character setting and the character setting processing time, and as a result, improve the efficiency of OCR character reading processing. It is something that can be done.
