Description

Description: TECHNICAL FIELD The present invention relates to a character / mark reading device for scanning a character / mark recorded on a form by a photoelectric conversion means and converting it into a binarized signal for recognition. Regarding

[Technical background of the invention and its problems] Conventionally, in an optical character / mark reading device (hereinafter, referred to as OCR), a method for confirming whether or not recognition of each data recorded on a form has been completed As for, with a printing device that performs numbering, etc., specific data indicating the completion of recognition is printed on the front surface or the back surface of the form after completion of recognition,
A method is known in which the operator confirms the print.

FIG. 2 is a diagram showing the overall configuration of a conventional OCR.

In the figure, 1 is a hopper for loading a form, 2 is a photoelectric conversion unit for converting the image of characters / marks recorded on the form into an electric signal, 3 is a printing unit for performing numbering, and 4 is recognition. Pocket select gate to select which pocket to transfer the form to
Indicates a reject pocket that cannot be recognized, that is, a reject pocket on which a rejected form is loaded, and 6 indicates a normal pocket on which a form that has been recognized normally is loaded.

By the way, in the conventional OCR configured in this way, if a conveyance problem occurs after the recognition of the form is completed and before the numbering is printed, the recognized form is actually recognized. There was a case that it was mistaken for a form that was not completed.

Also, in the case of a system in which multiple data items are set on one form and processing is completed for each data item, if a problem occurs before recognition of all data items is completed. , The operator investigates up to which item in which form the data processing has been completed, and in some cases a new form for additional processing is recorded in which only unrecognized data is recorded in order to avoid inputting duplicate data. There was a problem that I had to create it.

[Object of the Invention] The present invention has been made to solve the problems of the conventional OCR as described above, and even if a trouble occurs before the recognition of the data item of each form is completed, the operator is greatly affected. The purpose is to provide OCR with high processing efficiency that does not impose a burden and that prevents the occurrence of operational errors as much as possible.

[Summary of the Invention] That is, the character / mark reading device of the present invention includes a reading unit that reads characters / marks recorded in a plurality of areas to be read on a form, and a form image that holds image data read by the reading unit. Storage means, and recognition means for performing recognition processing using each of the read areas of the image data held in the form image storage means as a processing unit;
A symbol printing unit that prints a symbol indicating that the recognition is completed at a predetermined position on the form each time the recognition process of one processing unit by the recognition unit is completed, and image data stored in the form image storage unit. From the detecting means for detecting the symbol indicating that the recognition has been completed, and when the symbol indicating that the recognition has been completed is detected by this symbol detecting means, the processing unit corresponding to the symbol is recognized in the recognizing means. It is characterized by comprising a control means for performing control so as to exclude the recognition processing target.

Embodiments of the Invention Hereinafter, details of embodiments of the present invention will be described with reference to the drawings.

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

In the figure, 10 is a character / mark recorded on the form.
A photoelectric conversion unit for converting into a digitized electric signal, 11 is a sheet memory for holding the entire image of one sheet, and 12 is a recognition for recognizing characters / marks recorded on the sheet from the binarized signal. , 13 is a control unit for controlling the entire device,
14 is an external computer that performs subsequent processing of the recognized data,
Reference numeral 15 is a transport unit for transporting each form, 16 is each motor in the transport unit 15, 17 is a printing unit for performing printing such as numbering, and 18
Is a print head in the printing unit 17.

Next, the operation of the OCR of this embodiment will be described.

First, the external computer 14 transfers the control information (hereinafter referred to as FC) of the form to be read to the OCR, and then the command to start reading is input. Then, the control unit 13
Then, the conveyance unit 15 is controlled by the command to start the conveyance of the form.

When the form starts to be conveyed, when each form passes through the photoelectric conversion unit 10, the data recorded on each form is converted into a binarized electric signal and stored in the sheet memory 11.

When the entire image of one form is stored, the form is conveyed to the numbering start position of the printing unit 17 and stopped. At the same time, the recognition unit 12 starts recognition of data.

Here, the recognition of the data is started from the numbering print area, and when the data indicating the completion of the recognition is not recorded in the numbering print area, the recognition processing is performed from the first line of the form according to the given FC, The read data is output to the external computer 14. Then, the external computer 14 processes the received data, and if the normal processing is performed, the data (character string) indicating that the processing of the first line is completed is placed at a predetermined position on the form. The command and data to be printed are output to the control unit 13, and then the reading start command of the second line is output.

At this time, the OCR side prints the received data at a predetermined position on the form, and the form is conveyed by the amount of the printed data. After the above, the recognition processing of the data in the second row is started.

Similarly, the data recognition process proceeds to the last line of one form, and the form 15 for which the data recognition process of all lines is completed is conveyed to the normal pocket 6 by the conveyance unit 15.

On the other hand, when the data indicating the completion of the recognition is recorded in the numbering print area, the OCR interprets the data, skips the read line meaning the data, and similarly performs the recognition process.

That is, in the OCR of the present embodiment, even if one form is once input to the recognition processing line and is rejected due to a temporary trouble, if it is input to the recognition processing line again, the recognition processing is already completed. Since the read line is skipped and recognition is performed, the same data is not recognized twice. If it is rejected even if the input is performed again, the cause may be investigated by checking the item in which the data indicating the recognition completion is not recorded.

The data indicating the completion of recognition may be interpreted by the OCR side or the external computer side.

As described above, in the OCR according to the present embodiment, even when a trouble occurs before the recognition process is completed, it is not necessary for the operator to investigate which item of which form has been recognized unlike the conventional OCR. .

Also, the external computer side does not need to perform the process of checking the duplication of the input data, so that the system is simplified and the processing efficiency is dramatically improved.

[Effects of the Invention] As described above, the OCR of the present invention is a document image for reading characters / marks recorded in a plurality of areas to be read on a document and a document image for holding image data read by the document reading device. A storage means, a recognition means for performing recognition processing by using each read area of the image data held in the form image storage means as a processing unit, and each time the recognition processing of one processing unit by this recognition means is completed, the form is processed. Symbol printing means for printing a symbol indicating that the recognition has been completed at a predetermined position above, and detection means for detecting the symbol indicating that the recognition has been completed from the image data held in the form image storage means, When the symbol indicating that the recognition is completed is detected by the symbol detecting means, the processing unit corresponding to the symbol is recognized by the recognizing means in the recognizing means. Since it has control means for controlling to exclude it from the target of processing, even if trouble occurs before recognition of each form is completed, it does not place a heavy burden on the operator and induces an operation error. It is prevented as much as possible. Further, the processing system for checking the recognition is simplified, and the processing efficiency is dramatically improved.
