Abstract

PURPOSE:To attain quick and proper processing by controlling the operation according to the result of recognition of mark sheet information. CONSTITUTION:A mark sheet recognition section 5 detects a mark sheet identification mark from inputted picture information and reports the result of detection, recognition and analysis to a main control section 1 after the detection. When the priority of original reception is designated, even if the 1st original is mis-detected as the mark sheet, since all the originals are received and recorded, the recognition error processing suitable for the environment is implemented even when mis-detection or recognition error of the mark sheet takes place.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an information communication device such as a facsimile device that controls operations such as relaying by recognizing information written on a received mark sheet (mark sheet information). In particular, it relates to a mark sheet information recognition error handling method.

In the conventional facsimile operation mode, when a document is sent from one station to multiple stations in remote locations, one of the multiple stations or a station close to it is used as a relay station, and a relay request is made to this relay station. There is a method in which the original is sent to the remaining b stations, and the original is distributed from a relay station to the remaining b stations. Using this relay function has benefits such as reducing communication costs.

Conventionally, facsimile machines that can be used as such relay stations recognize information written on mark sheets (mark sheet information) received as image information in the same way as original documents, and
Operations such as relaying were controlled according to the mark sheet information.

An example of a mark sheet used for this purpose is shown in Part 5.
As shown in the figure. lla and llb are identification marks of the mark sheet, 12a and 12b are marks indicating the entry line of the mark sheet type, 13a and 13b are marks indicating the entry line of the sender, and 14a and 14b are marks indicating the entry line of the destination. Information on the sheet type, sender, and destination are entered as marks in each entry line.

When making a relay request, the sender fills in the necessary information, sends a five-marked sheet like a normal manuscript, and then sends the manuscript.

The 7 fax I7 device of the relay station sends the received image information of the first page to the mark sheet recognition section, and detects the mark sheet identification marks lla and llb. When the marks lla and Ilb are not at the predetermined positions, normal document reception is performed.

When the marks Ila and Ilb are detected, it is determined that they are image information of the mark sheet, and each mark 12a and 12b is detected.
, 13 a , 13 b , 14 a
, 14 b is used as a reference to recognize the information entered in each line. In the case of a relay request, the image information of the received document is accumulated, and when the reception is completed, the image information of this document is distributed to the destination station recognized from the mark sheet, and finally the sender (relay request source) Report the relay results to.

Now, even if there is a similar mark or the like in the position of the identification mark on the mark sheet, even if it is an ordinary document, the document will be mistakenly identified as a mark sheet. In this case, mark sheet information is recognized for the document, but this recognition naturally results in an error.

Even if a mark sheet is detected correctly, similar recognition errors may occur due to skewed feeding, writing errors, dirt on the sheet surface, etc. during transmission.

Conventional facsimile machines terminate communication at that stage when such a mark sheet information recognition error occurs.

Problems to be Solved by the Invention However, this mark sheet information recognition error processing method has the following problems.

If a recognition error occurs in the mark sheet information, it will simply be a communication error due to a disconnection of the line at the sender. Even if there is an error, it is not possible to determine whether the error is due to incorrect detection of the mark sheet, or whether the mark sheet is skewed, smudged, or has a writing error. Even on the receiving station side, in the case of a mark sheet information recognition error, no record of the mark sheet or manuscript remains, so it is difficult to recognize the fact or the cause.

As a result, if a communication error occurs due to a recognition error due to erroneous detection of a mark, no matter how many times the retransmission is repeated, the communication error does not occur, and normal document transmission becomes impossible. Even if the recognition error is due to dirt on the mark sheet or a mistake in writing, the user will retransmit without noticing the cause, resulting in repeated communication errors.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for handling mark sheet information recognition errors that can solve the above-mentioned problems.

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

In addition, the present invention is configured to select and execute either the recognition error process or the recognition error process that terminates communication midway in accordance with a selection designation.

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

Even if a recognition error 2- occurs due to erroneous detection of a mark sheet or an error in marking the mark sheet, dirt, skew, etc., the document case or mark sheet that was erroneously detected on the receiving side will be processed as a normal document, and its image information will be recorded. The occurrence and cause of a recognition error can be easily determined and processes such as notifying the sender can be quickly performed.

1. In the case of facsimile IJ devices that are frequently requested for relays using mark sheets, by terminating communication when a recognition error occurs, unnecessary recording of relay request documents can be reduced, and conversely, mark sheets can be In the case of facsimile machines, which are rarely used, priority is given to document reception, and the occurrence of communication errors due to normal documents being mistaken for mark sheets is reduced. Recognition error processing can be performed.

Embodiment FIG. 1 is a schematic diagram of a facsimile machine according to an embodiment of the present invention. Reference numeral 1 denotes a main control section that controls the entire facsimile machine. Control of mark sheet information recognition error processing related to the present invention is also performed by this main control section 1. 2 is a line control unit consisting of a network control circuit and a modem;
3 is a COD EC unit that performs a restoration button for received data and encodes transmitted data; 4 is an image memory unit that stores image information; 5 is a mark sheet recognition unit that detects mark sheets and recognizes and analyzes mark sheet information; 6 is a panel section for operating and displaying the facsimile machine.

7 is a reading section for reading a transmitted original or a mark sheet, and 8 is a recording section for recording received image information and the like.

This facsimile machine is capable of performing two types of mark sheet information recognition error processing, ``priority to document reception'' and ``priority to mark sheet'', and the selection thereof 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 explained. FIG. 2 is a 7-low chart of its operation. However, to simplify the explanation, it is assumed here that the mark sheet is used only for relay requests. The mark sheet shall be in the format shown in Figure 5.

When the main control unit 1 starts receiving, the received data (mark sheet or encoded data of the first ordinary original) is coded.
The C section 3 sequentially restores the image information, and the restored image information is stored in the image memory section 4 and input to the mark sheet recognition section 5 (STI.ST2). The mark sheet recognition unit 5 identifies the mark sheet identification mark ll from the input image information.
a, llb is detected, and when detected, the mark sheet information (sheet type, source, destination) is recognized and analyzed. The results of such detection, recognition and analysis are sequentially reported to the main control unit l.

The main control unit 1 checks whether the mark sheet identification mark is detected at a predetermined position (S T 3), and if it is not detected, stops inputting image information to the mark sheet recognition unit 5, and resumes normal document reception operation. Let it happen (ST13, 1
4. 15). That is, the image information from the first document to the last document is restored and stored in the image memory section 4, and is sequentially recorded in the recording section 8.

marksee} If an identification mark is detected at a predetermined position,
When the main control unit has finished recognizing and analyzing the mark sheet information, it checks whether there is a recognition error (ST4,
ST5).

If it is not a recognition error, the main control unit 1 restores the image information in the last document cabinet and stores it in the image memory unit 4 (ST
6, ST7). When this reception process is completed (the line with the sender is disconnected), the main control unit l makes a call to each destination recognized from the mark sheet information, and provides image information of the received document stored in the image memory unit 4. is encoded by the CODEC unit 3 and transmitted (ST8, .ST9). When the distribution ends at the final destination i, the main control unit 1 creates a relay result report and transmits the image information to the sender (relay requester) (STIO).

If an error occurs in recognition of mark sheet information, the main control unit 1 selects "mark sheet priority" as the selection designation for recognition error processing.
(ST11), and if "mark sheet priority" is specified, communication is immediately terminated (ST12). The contents of this "mark sheet priority" recognition error processing are the same as the conventional recognition error processing.
A communication error occurs at the sender.

If "mark sheet priority" is not selected, the main control unit 1 determines that recognition error processing of "manuscript reception priority" is specified, and performs control from step ST14 onwards.

That is, the communication continues, and the image information currently being received is handled in the same way as the image information of a normal original, and is stored in the image memory section 4 and sequentially recorded in the recording section 8.

Subsequent pages are similarly restored, stored, and recorded in sequence. In other words, it is a normal document reception process.

In this manner, when the recognition error process of "original reception priority" is selected, all originals are received and recorded even if the first original is mistakenly detected as a mark sheet during normal original transmission. In other words, the desired communication is completed. Therefore, in the case of a facsimile machine that receives relay requests using mark sheets infrequently, it is generally advantageous to specify "original reception priority" because communication errors due to erroneous detection of mark sheets can be prevented. In addition, even if an error occurs in recognizing the mark sheet information for relay requests,
Since the mark sheet is received and recorded, the receiving side can quickly process the recognition error.

On the other hand, in the case of a facsimile machine that frequently receives relay requests using mark sheets, if recognition error processing of "mark sheet priority" is specified, wasteful reception recording of documents to be relayed can be avoided.

FIGS. 3 and 4 show signal sequences between the calling station and the called station when a mark sheet information recognition error occurs. At least the called station is the facsimile machine of this embodiment. 1, FIG. 3 shows the case of "original reception priority", and FIG. 4 shows the case of "mark sheet priority".

Following the exchange of CNG (ring tone), CED (2 lOOHz called station identification signal), DIS (digital identification signal that conveys the capabilities of the called terminal), and CSI (called terminal identification signal), DOS (digital command signal) When the communication mode is transmitted, TSI (transmitting terminal identification number) and TCP (modem training signal) are sent, and CFR (reception readiness confirmation signal) is returned, sending of the first facsimile message begins. Ru.

When "Original Reception Priority" is specified, as shown in Figure 3, an N error occurs in the mark sheet information (including erroneous detection of the mark sheet) while receiving the first facsimile message.
Continue communication even if this occurs. The end of the first facsimile message and the sending of the next original product are notified by an MPS (multipage signal), and when an MCF (message confirmation signal) is returned in response, the second facsimile message is sent. When the sending of the facsimile message for the last document is completed, the EOP (procedure end signal) and MCF are exchanged, and the DCN (line disconnection command) is sent to disconnect the line and end the communication.

When "Mark sheet priority" is specified, as shown in Figure 4, if a mark sheet information recognition error (including erroneous mark sheet detection) occurs while receiving the lth facsimile message, the line will be disconnected at that point. disconnect and cause a communication error.

In this case, we have explained the case where a relay request is made using a mark sheet as an example, but a facsimile machine that can use a mark sheet to request operations such as "confidential", "post office box", "timer transmission", etc. Even if the button is pressed, the recognition error processing method of the present invention can be applied.

Effects of the Invention As is clear from the above description, the present invention allows communication to continue when a mark sheet information recognition error occurs,
Since all received image information is processed as image information of a normal original, it is also possible to send originals that are mistakenly detected as mark sheets, or due to misdetection of mark sheets, mistakes in marking sheets, dirt, skew, etc. Even if a recognition error occurs, the receiving side can easily determine the occurrence and cause of the recognition error, and can quickly take measures such as notifying the sender. Since you can select which recognition error process to end, in the case of facsimile machines, etc., where relays using mark sheets are frequently requested, wasteful document recording due to recognition errors can be reduced, and conversely, the frequency of use of mark sheets can be reduced. This has the effect that recognition error processing suitable for the environment in which the facsimile machine is used can be performed, such as giving priority to document reception in the case of a facsimile machine or the like with a small size.
