Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information communication device such as a facsimile device which controls operations such as relay by recognizing information (mark sheet information) written on a received mark sheet, and more particularly, The present invention relates to a mark sheet information recognition error handling method.

2. Description of the Related Art As a facsimile operation mode, when a manuscript is sent from one station to multiple remote stations, one of these multiple stations or a station close to it is used as a relay station, and the relay station is requested to relay. There is a method in which the manuscript is sent by using the relay station and the manuscript is sent to the remaining stations. Use of this relay function has advantages such as reduction of communication costs.

Conventionally, a facsimile machine that can be used as such a relay station recognizes the information (mark sheet information) written on the mark sheet received as image information, like the original document,
The operation control such as relay according to the mark sheet information has been performed.

The fifth example of a mark sheet used for such a purpose
Shown in the figure. 11a and 11b are identification marks on the mark sheet, 12a and 1
2b is a mark indicating the entry line of the mark sheet type, 13a, 13
b is a mark indicating the entry line of the sender, and 14a and 14b are marks indicating the entry line of the destination. The sheet type, source, and destination information are written as marks on each entry line.

When making a relay request, the sender sends a mark sheet in which necessary items are entered in the same manner as an ordinary manuscript, and then sends the manuscript.

In the facsimile device of the relay station, the received image information of the first page is sent to the mark sheet recognition section to detect the mark sheet identification marks 11a and 11b. This mark 11a, 1
When 1b is not in the predetermined position, normal document reception is performed.

When the marks 11a and 11b are detected, it is determined that the information is image information of the mark sheet, and the marks 12a, 12b, 13a, 13b, 14a, 14
Recognize the information entered in each row based on b. In the case of a mark sheet for relay request, the image information of the manuscript received continuously is accumulated, and when reception is completed, the image information of this manuscript is delivered to the destination station recognized from the mark sheet, and finally to the sender (relay requester). Report the relay result.

Now, even if a normal document has a similar mark or the like at the position of the identification mark on the mark sheet, the document is mistaken as a mark sheet. In this case, the mark sheet information is recognized for the original, but this recognition naturally causes an error.
Even when the mark sheet is correctly detected, the same recognition error may occur due to skewing at the time of transmission, entry error, dirt on the sheet surface, and the like.

In the conventional facsimile apparatus, when such a mark sheet information recognition error occurs, communication is terminated at that stage.

However, such a mark sheet information recognition error processing method has the following problems.

When an error in recognizing mark sheet information occurs, a communication error due to a line disconnection occurs only at the sender.Therefore, whether the cause is a mark sheet information recognition error or a line or receiving station failure is recognized. Even if there is an error, it is not possible to judge whether it is due to the erroneous detection of the mark sheet, or due to skewed marks on the mark sheet, stains, erroneous entries, etc. Even on the receiving station side, in the case of a mark sheet information recognition error, since no mark sheet or document is recorded, it is difficult to notice the fact and cause.

As a result, if a communication error occurs due to a recognition error caused by the erroneous detection of the mark sheet, the communication error occurs even if the retransmission is repeated many times, and normal document transmission becomes impossible. Even if the recognition error is caused by dirt on the mark sheet or an entry error, the communication error is repeated without re-transmission without noticing the cause.

It is an object of the present invention to provide a mark sheet information recognition error processing method capable of solving the above problems.

Means for Solving the Problems In order to solve the above problems, the present invention recognizes mark sheet information from image information of a mark sheet received before a document and controls an operation according to the recognition result, such as a facsimile device. In the above, when the recognition error of the mark sheet information occurs, the communication is continued and all the received image information is processed as the image information of a normal document.

Further, the present invention has a configuration in which either the recognition error processing or the recognition error processing for terminating the communication is selected and executed according to the selection designation.

Action Even if a recognition error occurs due to erroneous detection of the mark sheet, the document is processed as a normal document, so that the purpose of document transmission can be achieved.

Even if a mark sheet is erroneously detected or a recognition error occurs due to a mark sheet entry error, dirt, skew, etc., the document or mark sheet erroneously detected on the receiving side is processed as a normal document and its image information is recorded or stored. Therefore, it is easy to determine the occurrence and cause of the recognition error,
It is possible to quickly perform processing such as notifying the sender.

Further, in the case of a facsimile machine that is frequently requested to relay using a mark sheet, the communication is terminated when a recognition error occurs, thereby reducing unnecessary recording of a relay request document, and conversely, the mark sheet is mostly Recognizing errors that are suitable for the environment in which an information communication device such as a facsimile device is used, such as prioritizing document reception in the case of a facsimile device that is never used, and reducing the occurrence of communication errors caused by mistakenly scanning a normal document as a mark sheet. Processing can be performed.

Embodiment FIG. 1 is a schematic configuration diagram of a facsimile apparatus according to an embodiment of the present invention. Reference numeral 1 is a main control unit that controls the entire facsimile apparatus. The control of the mark sheet information recognition error processing related to the present invention is also performed by the main control unit 1. 2 is a line control unit including a network control circuit and a modem,
3 restores received data and encodes transmitted data
A CODEC section, 4 is an image memory section for accumulating image information, 5 is a mark sheet recognition section for detecting a mark sheet and recognizing / analyzing the mark sheet information, and 6 is a panel section for operating and displaying the facsimile apparatus. Reference numeral 7 is a reading unit for reading a transmission original or a mark sheet, and 8 is a recording unit for recording received image information and the like.

In this facsimile apparatus, two types of mark sheet information recognition error processing, "original reception priority" and "mark sheet priority", can be performed, and the selection can be specified by operating the panel unit 6.

The operation of the facsimile apparatus configured as described above as a called station will be described. FIG. 2 is a flowchart of the operation. However, in order to simplify the explanation, the mark sheet is used here only for the relay request. The mark sheet is assumed to be in the format shown in FIG.

When the main control unit 1 starts reception, the received data (mark sheet or encoded data of the first ordinary document) is sequentially restored by the CODEC unit 3, and the restored image information is accumulated in the image memory unit 4 and the mark sheet recognition unit Input to 5 (ST1, ST2). The mark sheet recognition unit 5 determines the mark sheet identification marks 11a and 11b from the input image information.
Is detected, and when it is detected, mark sheet information (sheet type, sender, destination) is recognized and analyzed. The results of such detection and recognition / analysis are sequentially reported to the main control unit 1.

The main control unit 1 checks whether or not the mark sheet identification mark is detected at a predetermined position (ST3), and if not detected, the input of image information to the mark sheet recognition unit 5 is stopped and a normal document receiving operation is performed. (ST13, 14, 15).
That is, the image information from the first original document to the last original document is restored and accumulated in the image memory unit 4, and is sequentially recorded by the recording unit 8.

When the mark sheet identification mark is detected at a predetermined position,
When the recognition / analysis of the mark sheet information is completed, the main control unit 1 checks whether or not there is a recognition error (ST4.
ST5).

If there is no recognition error, the main control unit 1 restores the image information up to the last document and stores it in the image memory unit 4 (ST
6, ST7). When this receiving process is completed (the line with the sender is disconnected), the main control unit 1 makes a call to each destination recognized from the mark sheet information, and the image information of the received document stored in the image memory unit 4 is stored. Is encoded by the CODEC unit 3 and transmitted (ST8, ST9). When the delivery to the final destination is completed, the main control unit 1 creates a relay result report,
Send the image information to the sender (relay requester) (ST
Ten).

When a mark sheet information recognition error occurs, the main control unit 1 selects the recognition error process as “mark sheet priority”.
Is checked (ST11), and if "mark sheet priority" is designated, the communication is immediately terminated (ST12). The content of the "mark sheet priority" recognition error processing is the same as the conventional recognition error processing, and the sender causes a communication error.

If it is not "mark sheet priority", the main control unit 1 determines that the "original reception priority" recognition error processing is designated, and performs the control from step ST14. That is, the communication is continued, and the image information currently being received is treated in the same manner as the image information of the ordinary document and is sequentially recorded in the recording unit 8 while being accumulated in the image memory unit 4. The subsequent pages are similarly sequentially restored, accumulated, and recorded. That is, the normal document receiving process is performed.

In this way, if the "original reception priority" recognition error processing is selected, even if the first original is erroneously detected as a mark sheet in normal original transmission, reception and recording of all originals is performed. That is, the intended communication is terminated. Therefore, in the case of a facsimile apparatus that rarely receives a relay request using a mark sheet, it is generally advantageous to specify "original reception priority" because it is possible to prevent a communication error from occurring due to an erroneous detection of the mark sheet. Also, even if a recognition error of mark sheet information for relay request occurs,
Since the mark sheet is received and recorded, the receiving side can quickly perform processing for the recognition error.

On the other hand, in the case of a facsimile apparatus that receives a relay request using a mark sheet at a high frequency, if the recognition error process of "mark sheet priority" is designated, useless reception and recording of a document to be relayed can be avoided.

3 and 4 show a signal sequence between a calling station and a called party when a mark sheet information recognition error occurs. At least the called station is the facsimile apparatus of this embodiment. In addition, FIG. 3 shows the case of “document reception priority”
The figure shows the case of "mark sheet priority".

Exchange of CNG (ring tone), CED (2100Hz called station identification signal), DIS (digital identification signal that conveys the ability of the called terminal), CSI (callee terminal identification signal) followed by DCS
Communication mode is transmitted by (digital command signal), then TSI (transmitting terminal identification number) and TCF (modem training signal) are transmitted, and CFR (reception preparation confirmation signal)
Is returned, the transmission of the first facsimile message starts.

When "Original Document Receiving Priority" is specified, as shown in Fig. 3, mark sheet information recognition error (including erroneous mark sheet detection) during reception of the first facsimile message.
Even if occurs, communication is continued. When the end of the first facsimile message and the sending of the next original are notified by MPS (multi-page signal), and the MCF (message confirmation signal) is returned in response thereto, the second facsimile message is sent. When the sending of the facsimile message of the final document is completed, the EOP (procedure end signal) and MCF are exchanged, DCN (line disconnection command) is sent to disconnect the line, and the communication ends.

When "Mark sheet priority" is specified, if a mark sheet information recognition error (including erroneous mark sheet detection) occurs during reception of the first facsimile message, the line is switched at that point, as shown in Fig. 4. Disconnect and cause a communication error.

In the above description, the case of making a relay request using a mark sheet has been described as an example, but a facsimile machine that can request operations such as "confidential", "post office box", "timer transmission" using the mark sheet is also possible. The recognition error processing method of the present invention can be applied.

EFFECTS OF THE INVENTION As is apparent from the above description, the present invention continues communication when a recognition error of mark sheet information occurs,
By processing all received image information as image information of normal originals, it is possible to send originals that are erroneously detected as mark sheets, and erroneous detection of mark sheets or recognition errors due to mark sheet entry errors, stains, skewing, etc. Even if the error occurs, the receiving side can easily determine the occurrence and the cause of the recognition error and promptly perform the processing such as notifying the sender, and the recognition error processing or the communication is terminated on the way. Since either recognition error processing can be selected, useless document recording at the time of recognition error is reduced in the case of a facsimile machine that is frequently requested to relay using a mark sheet, and conversely the mark sheet is used less frequently. Recognition error processing suitable for the usage environment of the facsimile machine, such as prioritizing document reception in the case of a facsimile machine. And it has a effect that it is possible to perform.
