[Problem that the invention seeks to solve]

This type of conventional mark sheet communication system only has the function of sending only one information, either a code signal or a pattern signal, to the information processing device 2 for the same mark sheet. Even if an abnormality was found in the code signal received from the pattern signal/code signal converter 3 in 4, it could not be verified any further. It can be said that it is impossible to recognize characters and symbols written on mark sheets with 100% accuracy using the current PTCE6. Even if the recognition accuracy is good, it is 99.9
% accuracy. On the other hand, in the case of characters, the number of characters that can be written on a mark sheet is approximately 700 for A4 size and approximately 1000 for B4 size, and as the number of characters written increases with the spread of mark sheet communication method, errors will occur with a certain frequency. An abnormal code signal containing recognition will be included. Various countermeasures can be considered to prevent erroneous processing caused by such abnormal code signals. Verify by writing the number of letters and symbols written on one of them on the mark sheet, or if all the characters are numbers, write the sum or part of the sum on the mark sheet and verify. There are methods. There is also a method in which the information processing device 2 is provided with means for automatically checking for impossible numbers, characters, number strings, and character strings. However, even if such countermeasures are taken, there is no other way than to skip that part of the process.

[Means to solve the problem]

In order to solve the conventional problems, the present invention inputs a mark sheet into a communication network as a pattern signal using a facsimile machine, converts the characters and symbols written on the input mark sheet into code signals, and connects the mark sheet to the communication network. In a pattern signal/code signal conversion device installed in a communication network that connects a facsimile device and an information processing device, which has a function of transmitting the code signal to the information processing device, the pattern signal is held and the code signal is sent from the communication network to the information processing device. If the information processing device finds an abnormality in the received code signal after transmitting the pattern signal to the communication network, the information processing device sends a pattern signal transmission request signal to the communication network, and then,
It is characterized in that the pattern signal of the reserved mark sheet is sent from the pattern signal/code signal conversion device to the information processing device.

[Effect]

According to the present invention, an information processing device can determine characters and symbols written in an abnormal code signal portion, and can cover the recognition accuracy of a device that converts a pattern signal into a code signal. This will be explained 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, and 11 is a pattern signal holding buffer. Other same reference numerals as in FIG. 6 indicate the same parts. To operate this, first set switch 9 to the a ₁ side and switch 10
Set to _b1 side. In this state, the mark sheet pattern signal inputted from the facsimile device 1 is transferred to the facsimile device side signal buffer 5 of the pattern signal/code signal converter 3. In pattern signal/code signal converter 3, PTCE6
The pattern signal is converted into a code signal and sent to the information processing device 2 via the information processing device side signal buffer 8. At this point, conventionally, the pattern signal in the signal buffer 5 on the facsimile machine side was erased, but the pattern signal in the signal buffer 1 on the facsimile machine side was erased.
1, the pattern signal in the signal buffer 5 on the facsimile device side is erased. When the information processing device 2 requests transmission of a pattern signal using the method described later, set the switch 9 to the _a2 side and the switch 1 to the a2 side.
0 is set on the _b2 side, and the pattern signal in the facsimile device side signal buffer 5 is sent to the information processing device 2 via the information processing device side signal buffer 8 without converting it into a code signal.

After sending the code signal to the information processing device 2 in this way, the information processing device 2 discovers some abnormality in the code signal and requests the communication network 4 to send the pattern signal. There are several possible signaling systems between the communication network 4 and the information processing device 2 that realize the method of sending data from the communication network 4 to the information processing device 2, but the two main schemes are shown in Figures 1 and 3. Shown below. Shown in Figures 1 and 3
EMS is a signal to notify the start of a call, PGT is a signal to notify the start of page transmission, PIX is a picture information signal consisting of a pattern signal or code signal,
REQ is a signal requesting sending a pattern signal,
CED is a signal to notify the end of the call, +RSP is EMS,
This is a signal that notifies that PGT, REQ, PIX, or CED has been successfully received.

FIG. 1 is an embodiment of one basic mark sheet communication method between a communication network and an information processing device according to the present invention, and shows a method of sending a code signal and a pattern signal to an information processing device 2 in one call. First, it sends out a PIX consisting of a code signal, then receives REQ and sends out a PIX consisting of a pattern signal. REQ if the pattern signal is not required in the information processing device 2
You can either display this in the message or skip sending the REQ. When each PIX has a large amount of information, it may be composed of multiple signals. Note that whether each PIX consists of a code signal or a pattern signal can be determined by providing a flag for discrimination in the header portion of the PIX signal.

FIG. 3 shows another embodiment of the mark sheet communication system between a communication network and an information processing device according to the present invention, and shows a method of sending a pattern signal to the information processing device 2 as a signal for a subsequent call. When the call ends
When it receives REQ, it starts the call again and sends PIX consisting of pattern signals. In this case, whether the page is composed of PIX consisting of code signals or PIX consisting of pattern signals is determined by
Discrimination is made by providing a flag for discrimination in the header part of the PGT signal.

Next, FIG. 4 shows a schematic example of the configuration of the information processing device 2 which receives the pattern signal following the code signal in this manner. 12 is a communication network side signal buffer;
13 is a central processing unit, 14 is a facsimile machine,
15 is a display device. Information processing device 2
Then, the code signal received from the communication network 4 is taken into the central processing unit 13 via the communication network side signal buffer 12 and processed. At this time, the central processing unit 13
If you find an abnormality in the code signal, please contact communication network 4.
Then, a pattern signal corresponding to the code signal received by the method shown in FIG. 1 or 3 is sent to the facsimile device 1 via the central processing unit 13.
4, or output to a display device 15 to be read by human eyes, for example. In this way, it is possible to take appropriate measures against abnormal code signals.
