FIG. 6 shows a schematic configuration of the pattern signal / code signal conversion device 3. 5 is a signal buffer on the equipment side, 6 is a device for converting a pattern signal into a code signal (hereinafter PTCE), 7 is a device for converting a code signal into a pattern signal (hereinafter CTP)
E) and 8 are signal buffers on the information processing apparatus side.

When the mark sheet is put into the facsimile device 1, it is converted into a pattern signal and inputted into the communication network 4. In the communication network 4, the pattern signal / code signal converting device 3 transfers the signal to the facsimile device side signal buffer 5. The pattern signal / code signal conversion device 3 converts the pattern signal into a code signal by the PTCE 6 and sends the code signal to the information processing device 2 via the signal buffer 8 on the information processing device side. The information processing device 2 analyzes the code signal and sends the information to the facsimile device 1 to the communication network 4 as the code signal. In the communication network 4, it is transferred to the signal buffer 8 on the information processing device side in the pattern signal / code signal conversion device 3. In the pattern signal / code signal conversion device 3, the code signal is converted into a pattern signal by the CTPE 7 and sent to the facsimile device 1 via the signal buffer 5 on the facsimile device side. The facsimile device 1 can obtain necessary information from the information processing device 2 as a facsimile image signal.

[Problems to be solved by the invention]

The conventional mark sheet communication system of this kind is
100% of the characters and symbols written on the mark sheet with PTCE6
It is impossible to recognize with the accuracy of. Even with good recognition accuracy, the accuracy is 99.9%. On the other hand, in the case of letters, the number that can be written on the mark sheet is about 700 for A4 version and about 700 for B4 version.
The number is about 1000, and if the number of written characters increases with the spread of the mark sheet communication method, unrecognizable characters or abnormal characters including erroneous recognition will be included with a certain frequency. If there is a character that cannot be recognized, a notification indicating that the character cannot be recognized is returned to the FAX user, and the FAX user needs to correct it and send it again, which is troublesome.

Also, if there is a misrecognized character, an abnormal code signal
It is delivered to the information processing device 2 without knowing that it is wrong. In order to prevent erroneous processing due to such an abnormal code signal, various countermeasures can be considered. The number of characters and the number of symbols described in one of them are entered on the mark sheet for verification, or when all the characters are numbers, the sum or part of the sum is entered on the mark sheet for verification. There are ways. There is also a method in which the information processing apparatus 2 is provided with a means for automatically checking numbers, characters, a number string, and a character string that cannot exist in advance. However, even if such a countermeasure is taken, there is no method other than skipping the processing of that portion.

[Means for solving problems]

In order to solve the conventional problems, the present invention inputs a mark sheet as a pattern signal from a facsimile device into a communication network, and a pattern signal / code signal conversion device installed in the communication network displays characters and symbols written on the mark sheet. In a mark sheet communication system having a function of converting into a code signal and sending it to an information processing device connected to a communication network, an identification information area is provided on the mark sheet, and the pattern signal / code signal conversion device is provided to the identification information area. Only for the mark sheet in which the predetermined identification information is found to be written, both the code signal and the pattern signal of the mark sheet are continuously transmitted from the communication network to the information processing device, and the information processing device receives the information. An abnormal code signal of the code signals It is characterized in that modified Zui.

[Action]

According to the present invention, even if there is a character that cannot be recognized in the communication network, the read character is delivered to the information processing apparatus 2, so that the FAX user can save the trouble of retransmitting the character. On the other hand, the information processing apparatus 2 allows the operator to judge the characters that the communication network cannot read by looking at the mark sheet sent as the pattern signal. On the other hand, even if there is a character that is erroneously recognized in the communication network, a pattern signal (mark sheet) is sent to the information processing device 2 following the code signal. By comparing with the mark sheet sent by the pattern signal, it is possible to discriminate the characters and symbols described in the abnormal code signal portion. The details will be described below with reference to the drawings.

〔Example〕

FIG. 2 shows a pattern signal / code signal conversion device 2 of the present invention. 9 and 10 are switches. To operate this, first, the switch 9 is set on the a ₁ side, and the switch 10 is set on the b ₁ side. In this state, the mark sheet pattern signal input from the facsimile device 1 is transferred to the facsimile device side signal buffer 5 of the pattern signal / code signal converter 3. In the pattern signal / code signal conversion device 3, the pattern signal is converted into the code signal by the PTCE6,
It is sent to the information processing device 2 via the signal buffer 8 on the information processing device side. At this point, the pattern signal in the signal buffer 5 on the equipment side was conventionally erased. However, without erasing, the switch 9 was set to the a ₂ side and the switch 10 was set to the b ₂ side, and the signal buffer on the equipment side signal buffer was set. The pattern signal in 5 is not converted into a code signal and is sent to the information processing device 2 via the signal buffer 8 on the information processing device side. At this point, the pattern signal in the signal buffer 5 on the device side is erased.

There are several possible signal systems between the communication network 4 and the information processing device 2 for realizing the method of continuously transmitting the code signal and the pattern signal to the information processing device 2 as described above. Is shown in FIGS. 1 and 3. PGT shown in FIGS. 1 and 3 is a signal for notifying the start of page transmission, PIX is an image information signal composed of a pattern signal or a code signal,
+ RSP is a signal notifying that PGT or PIX has been normally received.

FIG. 1 is an embodiment of a basic mark sheet communication system between a communication network and an information processing device of the present invention, and shows a method of sending a code signal and a pattern signal to the information processing device 2 in one page. First, the PIX is transmitted from the code signal, and then the PIX composed of the pattern signal is transmitted. Each PIX may consist of multiple signals when the amount of information is large. A flag for discrimination may be provided in the header portion of the PIX signal as to whether each PIX is composed of a code signal or a pattern signal.

FIG. 3 shows another embodiment of the mark sheet communication system between the communication network and the information processing device of the present invention, and shows a method of sending a pattern signal to the information processing device 2 as a signal of the subsequent page. In this case, whether the page is composed of the PIX composed of the code signal or the PIX composed of the pattern signal is determined by providing a discrimination flag in the header portion of the PGT signal. In the above description, the example in which the pattern signal is continuously transmitted on the line that transmits the code signal is shown. However, the code signal and the pattern signal (mark sheet) are transmitted from the communication network to the information processing device 2 by using different lines. The delivery does not impair the gist of the present invention.

Next, FIG. 4 shows an example of a schematic configuration of the information processing apparatus 2 which receives the pattern signal subsequently to the code signal in this way. 11 is a communication network side signal buffer, 12 is a central processing unit, 13
Is a facsimile device, and 14 is a display device. In the information processing device 2, the code signal received from the communication network 4 is taken into the central processing unit 12 via the communication network side signal buffer 11 and processed. At this time, if the central processing unit 12 finds an abnormality in the code signal, the central processing unit 12 receives a pattern signal corresponding to the code signal received from the communication network 4 in advance by the method shown in FIG. 1 or FIG. The signal is output to the facsimile device 13 or the display device 14 via the route and is read by, for example, human eyes. If you do this,
Appropriate measures can be taken against abnormal code signals.

On the other hand, when a pattern signal is transmitted from the communication network 4 to the information processing device 2 for all pages, the pattern signal / code signal of the facsimile device side signal buffer 5, the information processing device side signal buffer 8, etc. The average signal storage time in the converter 3 is lengthened and the number of these facilities is increased. This is not preferable because it leads to a charge up of the mark sheet communication method. In order to prevent this, if the present invention is further combined with the following method, the number of facilities is hardly increased, so that the service can be provided to the subscriber without increasing the financial burden.

FIG. 7 is an example of a mark sheet. Reference numeral 15 is a mark sheet, 16 is a system area, and 17 is a user area. The mark sheet 15 shown in FIG. 7 complies with the regulations of the facsimile communication network currently providing the service, and a detailed description thereof will be omitted, but the system area 16 is defined between the facsimile device 1 and the communication network 4. The user area 17 is an area used between the facsimile device 1 and the information processing device 2. Currently, in the facsimile communication network, the five digits from the left end of the system area 16 are the tenant number (also known as UP
P number). Since the right side of the 6th digit is unused, for example, if it is specified that the pattern signal is sent following the code signal only when the numeral "2" is entered in the 7th digit, the pattern signal is followed by the pattern signal for all pages. The average signal storage time in the pattern signal / code signal conversion device 3 such as the signal buffer 5 on the device side and the signal buffer 8 on the information processing device side does not become longer than that in the case of transmitting It is possible to provide services to subscribers without increasing financial burden.

〔The invention's effect〕

As described above, since the pattern signal (mark sheet) is sent after the code signal, even if there is a character that the communication network cannot recognize, it is delivered to the information processing device without being returned to the FAX user. , The convenience of FAX users is improved. Even if there are misread characters, the mark sheet itself is sent to the information processing device for important documents.
Trouble due to incorrect recognition can be prevented by operator intervention. Furthermore, since it is possible to send only the specified mark sheet to the information processing device, the pattern signal
The average storage time in the code signal converter does not become long, the number of these facilities hardly increases, and the service can be provided to the subscriber without increasing the economic burden.
