Abstract

PURPOSE:To prevent double transaction when a facsimile equipment sends again slip data and to attain fast processing for the system. CONSTITUTION:The facsimile equipment 1 sends slip data to a recognition device 2 via a communication line 3. In the recognition device 2, when the slip data is received, a character recognition section 7 recognizes characters of the slip data. A control section 41 extracts identification data and received date of the sender facsimile equipment 1 in the received slip data and extracts the character recognition result of the character recognition section 7 and stores the recognized data, the received date and the character recognition result of the facsimile equipment 1 into a storage section 5. When optional slip data is received, a discrimination section 42 compares the slip data with the recognized data stored in the storage section 5 and aborts the received slip data when the storage section 5 has the same data content with the sender data.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile character recognition system in which form data is transmitted from a facsimile device and a recognition device receives the form data for character recognition, and in particular, form data is transmitted from the facsimile device. At this time, it is possible to prevent double registration of the form data that the sender retransmitted and the form data that has already completed the form recognition before the failure occurred due to delay in form transmission due to some failure. The present invention relates to a facsimile character recognition system designed to prevent transactions.

[0002]

2. Description of the Related Art A facsimile machine transmits image data of a form to a preliminarily registered recognition device via a communication line, and the recognition device recognizes the character described in the form from the image data of the form. There is a character recognition system, a so-called FAX-OCR system.

In such a FAX-OCR system, when the form data is transmitted, some trouble occurs and the form transmission is delayed, and for example, a "communication error" or the like occurs during transmission of 10 forms collectively. When the error occurs, the sender does not know at what number the “communication error” has occurred, and therefore the documents transmitted up to that time may be collectively facsimile-transmitted from the first sheet.

[0004]

When such a "communication error" occurs, the recognition device on the receiving side stores the form image data immediately before the occurrence of the "communication error" in a file in the device. Therefore, it was possible to perform character recognition processing. However, in order to prevent “double transaction” when the sender retransmits the form data, the form image data already stored in the file in the device is not used and is discarded.

Therefore, in the recognition device, the character recognition process is started at a timing after the transmission of the form data from the transmitting side facsimile device is normally completed, so that the processing as the system is delayed, and such " It has been desired to solve the processing delay when the "communication error" occurs.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a system in which form data is transmitted from a facsimile device to a recognition device and the recognition device performs character recognition of the form data. The device identifies the sender's facsimile device for each form data sent, and
When a storage unit that stores data for identifying the data content and an arbitrary form data is received, the facsimile device that is the sender of the form data and the data content are received before being stored in the storage unit. It is provided with a determination unit that determines whether the content is the same as the content of the generated form data and discards the form data when the form data is the same.

[0007]

In the facsimile character recognition system of the present invention, when the form data is sent from the facsimile device to the recognition device, the determination unit of the recognition device causes the form data and the form stored in the storage unit. The data identification data is compared and judged. On the other hand, the storage unit stores the identification data of the form data received before that time, and the determination unit compares the identification data with the form data received this time, and if the same identification data exists. Discards the form data received this time.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a facsimile character recognition system of the present invention. The system shown is
The facsimile device 1 and the recognition device 2 and a communication line 3 for communicatively connecting them.

The facsimile machine 1 is a known facsimile machine which transmits and receives image data via the communication line 3. That is, read the image data of the form,
A transmission unit that transmits this to the communication line 3, a reception unit that receives the image data of the form via the communication line 3 and prints out the image data, a modem that controls the communication to the communication line 3, and the like. And a transmission unit including. Note that these configurations are omitted in the drawing.

The recognition device 2 receives the form data from the facsimile device 1 via the communication line 3, performs character recognition from the image data, and determines whether the received form data is resend data. If the data is resend data, the form data is discarded, and the system control unit 4, the storage unit 5, the receiving unit 6, the character recognition unit 7, and the entry processing unit 8 are provided.

The system control unit 4 is a processor for performing various processes as the recognition device 2, and the control unit 41.
And a determination unit 42. The control unit 41 is composed of a dedicated processor or program, and based on the form data received by the reception unit 6, the facsimile device 1 of the transmission source.
And the reception date and time and the form identification data for identifying the format of the character field of the form data, and the character recognition result of the form data recognized by the character recognition unit 7. It is a thing.

Further, when the recognition device 2 receives arbitrary form data, the determining unit 42 determines that the source and the data content of the form data are the same as the source and the data content stored in the storage unit 5. It is determined whether or not there is, and if they are the same, the form data is discarded.

That is, when the receiving unit 6 receives arbitrary form data, the determining unit 42 stores the facsimile identification data, the reception date and time, the form identification data, the character recognition result extracted by the control unit 41 in the storage unit 5. The facsimile identification data, the reception date and time, the form identification data, and the character recognition result of the corresponding form data are compared, and the facsimile identification data, the form identification data, and the character recognition result are the same, and the reception date and time are stored in the storage unit 5. When it is within the preset time from the stored reception date and time, the form data is determined to be retransmission data, and the data is discarded.

The storage unit 5 stores the facsimile apparatus 1 of the transmission source.
This is a memory for storing the facsimile identification data for identifying and the data content of the form data. Here, the data stored in the storage unit 5 is data indicating from which an arbitrary form is transmitted and what the content is,
The data format is not particularly limited, but in this embodiment, it is as follows. That is, these data are composed of the facsimile identification data taken out by the control unit 41, the reception date and time, the form identification data, and the character recognition result for each character field, and these data are stored by the control unit 41. It is configured.

FIG. 2 is a configuration diagram of a form information file stored in the storage unit 5. Further, FIG. 3 is a diagram showing an example of a form. The form information file includes FAX-ID (facsimile identification data), form reception date and time, form sheet ID (form identification data), and recognition results of the character fields 1 to M. Here, the FAX-ID is identification data for identifying which one of the plurality of facsimile devices 1 that makes a character recognition request via the recognition device 2 and the communication line 3 and transmits the data. It is sometimes transmitted to the recognition device 2 as facsimile identification data. The form reception date and time is the date and time when the form data is received.
The AX-ID and the form reception date and time are communication record data by the control unit 41.

The sheet ID of the form is identification data for indicating the form format such as in which part of the form the character field exists. For example,
In the case of the form 100 shown in FIG. 3, the field indicated by 102 is the sheet ID. Moreover, in FIG.
Reference numeral 1 is a correction mark for identifying the size of the form 100 and skew correction at the time of recognition, and 103 is a character field 1
~ M character fields consisting of character fields M.

Returning to FIG. 2, the recognition results of the character fields 1 to M of No4 to NoN are, for example, the character recognition result of the character field 1 is "A". It stores the result.

In FIG. 1, the receiving unit 6 receives the form data transmitted from the facsimile apparatus 1 via the communication line 3 and performs a predetermined decompression process to form image data of the form. . The character recognition unit 7 includes an image memory (not shown) for storing the form data received by the reception unit 6, and performs character recognition for each character field from the form data stored in this image memory based on the form format. Is. The entry processing unit 8 is an operation terminal for the operator to correct or confirm the character recognition result. The communication line 3 is composed of an analog public line, a digital dedicated line, or the like.

Next, the operation of the facsimile character recognition system thus constructed will be described. FIG. 4 is a flowchart in the case of retransmitting a form when some "communication error" occurs.

<Step S1> From the facsimile apparatus 1 on the transmission side, the forms A to H (in this example, eight sheets will be described)
Fax all together. <Step S2> A “communication error” occurs while receiving the image data of the form in the receiving unit 6 of the recognition device 2 through the communication line 3, and, for example, the form B is normally transmitted, but the form B is transmitted. It is assumed that the image data after C cannot be received by the recognition device 2. <Step S3> A “communication error” occurs, but the sender of the facsimile apparatus 1 does not know how many sheets of the form have been normally received, and therefore the forms A to H are retransmitted.

<Step S4> On the other hand, on the recognition device 2 side, when the form data is sent from the facsimile device 1, the form data is received by the receiving unit 6, and the control unit 41 characterizes the image data. The characters are sequentially transferred to the recognition unit 7, and the character recognition unit 7 executes a character recognition process. For example, in this case, since the forms A to B are normally received, the image data of the forms A to B is transferred to the character recognition unit 7 and the character recognition processing is performed. The character recognition processing in the character recognition unit 7 is to obtain the format of the form 100 from the correction data 101 and the sheet ID 102 of the transferred form 100, and perform character recognition for each character field 1 to M based on this format. This is the process to be performed.

<Step S5> The data of the forms A to B for which the recognition result is obtained is stored in the form information file of the storage unit 5 by the control unit 41. <Step S6> The retransmitted image data of the forms A to H is sequentially transferred to the character recognition unit 7 by the control unit 41, and the same character recognition process as the character recognition process of Step S4 is executed.

<Step S7> The form for which the recognition result is obtained is compared with the form information already stored by the determination unit 42 at the timing when the control unit 41 stores the data in the form information file. . <Step S8> If there is no form content showing the same transaction content, the control unit 41 stores the form recognition result transmitted later in the form information file, while there is a form content showing the same transaction content. In this case, the determination unit 42 controls the control unit 4 to discard the content of the form transmitted later without registering it.
Instruct 1.

Next, a method of comparing the information contents of the form by the determination unit 42 will be described. FIG. 5 shows the comparison flowchart. <Step S1> The determination unit 42 determines the FAX-ID recognized by the control unit 41 and the FAX of the form information file in the storage unit 5.
-Compare with ID. Here, when the FAX-ID is different, it is determined that the form is not retransmitted because the sender is different.

<Step S2> According to the date and time when the form is transmitted,
Determine whether it is a resend when a "communication error" occurs or another transaction. That is, it is determined whether the last communication date and time is within a predetermined time. Here, if a predetermined time of several hours has passed, or if the dates are different, it is determined that the form is not a retransmitted form. <Step S3> It is determined whether the sheet IDs of the form based on the recognition result of the character recognition unit 7 are the same. Here, if the sheet IDs are different, the form itself is different, so it is determined that the form is not a retransmitted form.

<Steps S4, S5> The contents are compared in character field units, and this is performed for all character fields. Here, if there are character fields with different contents, it is determined that the form is not a resend form because it is a different form. <Step S6> If all of the above-mentioned steps S1 to S5 are the same, it can be determined that the forms are the same (= resent), so the form data is not registered in the form information file and the data contents are changed. Discard.

<Step S7> Since at least one of the contents is different in the above steps S1 to S5, it can be determined that the forms are not the same. Therefore, the form data is registered in the form information file and the form is recognized. For example, the result is transferred to the host device (entry processing unit 8), and the process proceeds to the next process.

In the above embodiment, whether or not the data is retransmitted data is determined based on the FAX-ID, the communication date and time, the sheet ID of the form, and the character recognition result. However, for example, when the form format is fixed, etc. It is not necessary to determine the sheet ID of the form. Therefore, in such a case, the determination of the determination unit 42 may be performed based on the facsimile identification data, the reception date and time, and the character recognition result.

[0029]

As described above, according to the facsimile character recognition system of the present invention, the recognition device stores the identification data of the form data sent from the facsimile device, and the arbitrary form data is sent. If the same form data is stored, the form data is discarded if it is the same, so double transactions can be prevented and the form data must be retransmitted. However, the character recognition process can be executed promptly.
