Abstract

PURPOSE:To detect the input error of character data. CONSTITUTION:Character information is optically read by an image input part 11. That character information is inputted key from a key input part 14. A character collation part 15 compares data which characters are recognized by a character recognition part 12 read by the image input part 11 with the key inputted data. When the compared result shows equal, those data are outputted as proper data. When the result shows not equal, it is alarmed by a display part 13 to the effect that the correction of those data is required. After this alarm, the key inputted data are outputted as correct data. Since the error is detected by comparing the image input result with the key input result, the error can be detected even when logical decision is impossible by check digit or the like and since processing is enabled more speedily than the twice key input by a key puncher, man-hour for data input processing can be reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character reading device, and more particularly to an OCR (Optical) for reading characters on slips, forms, etc.
The present invention relates to a character reader such as a character reader.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 2, a character reading device of this type has an image input unit 11 for reading handwritten characters such as a form with a scanner and a character based on the image signal. The character recognition unit 12 for recognizing and the display unit 13 for displaying the recognized character are included.

Further, the conventional character reading device has an error judging section 17 for judging whether or not there is an error (misreading) in the recognized character, and a key input section 14 for inputting a correct character for the character in error. An output unit 16 is provided for sending the data of the character having no error and the character input by the key to the external device.

In such a configuration, first, the image input section 11
At, an image signal obtained by photoelectrically converting characters and figures on a form by a scanner or the like is input. Then, the character recognition unit 12
Cuts out characters from the image signal and recognizes them, and the display unit 13
Displays the recognized character data on the screen.

When the error determination unit 17 detects an error in the character data, the display unit 13 displays that fact. When the operator looks at the displayed contents and inputs data from the key input unit 14, the data is handled as correct data and is sent out from the output unit 16.

Here, in the error determination section 17, it is determined whether or not there is an error using a known check digit, or the product obtained by multiplying the unit price by the number is compared with the total amount. Or a logical determination is made by adding the amounts and comparing the total amount. As described above, when the error due to the logical operation can be determined, the error determination unit 17 can notify the operator of the presence or absence of the error, but the logical determination such as the case where the check digit is not added or the operation cannot be performed. If it is not possible, we cannot notify you. Therefore, in this case, the operator visually confirms the character or the image of the character and the reading result written on the form.

[0007]

By the way, in the so-called key punch work, after the key puncher key-inputs a character on the form, another key puncher key-inputs again and compares (verifies) both input data. Therefore, the input error is detected. This method is often used because the key puncher can perform key input processing faster and more accurately than visual confirmation processing.

If such key punching work is replaced by the above-mentioned conventional character reading device, an error must be detected by visual confirmation, which is slower than confirmation by key input.
Moreover, there is a drawback that the accuracy is low and the effect of introducing the device cannot be obtained.

The present invention has been made in order to solve the drawbacks of the prior art, and the object thereof is to detect an error in character recognition or a key input error to reduce the number of steps for inputting a slip by a key puncher. It is to provide a character reading device.

[0010]

A character reading device according to the present invention comprises a character reading means for optically reading character information to be input, a key input means for key-inputting the character information, and the character reading means. And comparing means for comparing the data read by the key with the data key-input from the key-input means, and processing means for processing the data as correct data when the comparison result shows a match. And

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a character reading apparatus according to the present invention, and the same parts as those in FIG. 2 are designated by the same reference numerals.

In the figure, the character reading apparatus of this embodiment is different from the conventional one in that a character collating section 15 is provided instead of the error determining section. The character collating unit 15 is input from the image input unit 11, and the character recognizing unit 12 is input.
The character data recognized in step 4 and the data input from the key input unit 14 are compared and collated. That is, unlike the conventional device, this device always inputs the data on the form by the image input unit 11 and the key input unit 14 and compares the both input data. If the comparison result shows a match, the data is treated as correct data, and if they do not match, a message indicating that the data needs to be corrected is displayed and the operator is prompted to enter a key.

In such a configuration, the image input unit 11 inputs an image signal in which characters and figures on a form are photoelectrically converted by a scanner or the like. Then, the character recognition unit 12 cuts out a character from the image signal and recognizes it, and the display unit 13 displays the recognized character data on the screen.

Next, when the operator inputs the data of the form displayed on the screen from the key input unit 14, the character collating unit 15
Compares the recognition result with the key input data. Then, if the comparison results are in agreement, the data is treated as correct data and output processing is performed from the output unit 16. As described above, since the OCR input and the key input are performed, the data processing can be performed faster than the key input by the key puncher twice.

On the other hand, if the comparison results do not match,
A message to that effect is displayed on the screen of the display unit 13 to notify the operator to prompt re-input of data. When the operator looks at the display on the screen and re-inputs the data from the key input unit 14, the character collating unit 15 treats the re-input data as correct data, and outputs it from the output unit 16. After that, the character matching unit 15 continues the comparison process from the next data. As described above, since the error judgment is made by comparing the input result by OCR and the key input result, the data input error can be detected even when the logical judgment by the check digit or the like is impossible.

In the present embodiment, the case of optically reading a character has been described, but the present invention is not limited to this and it is obvious that the present invention can be widely applied to the case where the logical judgment of an error is impossible.

Further, when the comparison result shows a non-coincidence, in the present embodiment, the fact is displayed on the display unit to notify.
Not limited to this, the operator may be notified by a buzzer sound or a message voice.

[0019]

As described above, according to the present invention, since an error is detected by comparing the image input result by OCR and the key input result, even if logical judgment by a check digit or the like is impossible. The effect is that an input error can be detected. Further, since the input results of the OCR and the keys are compared with each other to detect an error, the key puncher can perform the data processing faster than the key entry is performed twice, which has an effect of reducing the number of data input processing steps.
