DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art Recently, remote education such as home-based learning using a facsimile machine has been carried out in schools and study schools that study by communication. In addition, it is conceivable that a service company or the like transmits and receives a predetermined input format using various networks due to the enhancement of the network. In these cases, a facsimile machine is used to transmit a problem or the like from a school or a cram school to each home or a format to a person who receives service from various service companies, and each receiver outputs the received problem to a sheet.

[0003] Then, after writing the answer and the determined items on the paper on which the question and the input format are printed,
There is a method of replying from each recipient using a facsimile machine.

However, in this case, since only a reply is made with a small amount of image information added to the content of the received facsimile, it is not always necessary to output all of the received information to a sheet.

[0005] Even so, in order to add new image information to the received information, the information has to be once output on paper. Then, when transmitting the added image information,
A configuration for reading the paper is required. Therefore, a configuration for holding a sheet, a unit for printing on a sheet, and a reading unit is required, and there is a limitation in reducing the configuration of the main body.

[0006] Therefore, it is very unsuitable to carry, move and use the main body.

Further, since a reply is made only with a small amount of image information added to the contents of the received facsimile, a conventional example provided with a display capable of inputting by handwriting is also conceivable. Since both of the information and the added information are transmitted, there is a disadvantage that the amount of transmitted information increases, and communication time and communication fee increase.
Therefore, it has been unsuitable for such distance education and various services.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus which, in a simple configuration, greatly reduces the amount of information to be transmitted corresponding to received information.

[0009]

According to the present invention, there is provided a processing means for modulating and demodulating image information into an image transmission signal which can be transmitted and received on a line in accordance with a predetermined rule, and a first means for storing the received image information.
Storage means, input display means for displaying received image information, and displaying input information input by the user over the image information, and second storage means for storing input information input by the user And, identification determining means for detecting an identification signal transmitted and received in accordance with the image transmission signal, and by the output of the identification determining means, to transmit only input information input by the user, or to input information input by the user It is an object of the present invention to provide an electronic terminal device that switches whether to transmit received image information together.

[0010]

FIG. 1 is a block diagram showing one embodiment of the present invention. In this configuration, a transmission / reception switching unit 1 connected to a wireless or wired telephone line and switching transmission / reception (separation), a facsimile determination unit 2 for determining whether or not a received signal is a facsimile signal, A difference request discriminator 3 for judging whether or not there is a difference request at a predetermined data position of the signal from the signal based on a signal from the facsimile discriminator 2; A difference setting unit 4 that allows the user to set the difference transmission when it is determined from the received information displayed on the display unit 6a that there is a difference request or when it is determined that the other party who has transmitted the received information can respond to the difference information in advance. An input unit 6b integrated with the display unit 6a and constituted by, for example, a digitizer with an LCD, for inputting by a user; and a memory unit 7 for separating and storing the input information and the received information. Setting of the difference transmission is in a notification unit 8 for informing whether or not made. Here, the display unit 6a and the input unit 6b constitute the input display unit 6.

Next, the operation will be described with reference to FIG.

In this embodiment, a normal signal flow is performed.
The facsimile information received via the transmission / reception switching unit 1-processing unit 5-display unit 6a is demodulated and displayed on the display unit 6a.
Then, if necessary, it can be outputted to an output means (not shown) (such as a printer) and outputted as paper.

Further, it is possible to modulate the information input to the input unit 6b through the path of the input unit 6b, the processing unit 5 and the transmission / reception switching unit 1, and to perform facsimile transmission.

That is, the received facsimile information is written into the reception area of the memory unit 7 as reception information,
It is displayed on the display unit 6a. While the received information is displayed, a corresponding reply is input. As a result, the input reply is displayed so as to be superimposed on the received information and written in the reply area of the memory unit 7. Therefore, the received information and the response are displayed as if the response were written in the received information, but the storage areas are different.

Next, a description will be given of a method of transmitting / receiving data with a reduced amount of information. First, the facsimile determination unit 2 determines whether the received signal is a facsimile signal, and activates the difference request determination unit 3 based on the determination result.

The activated difference request judging section 3 judges whether or not there is information indicating a difference request at a predetermined data position of the received signal. If there is no difference request, it is handled as a normal facsimile, and at the time of transmission, information in which reception information and reply information are superimposed is transmitted.

On the other hand, if there is difference request data, a signal to the effect that the request has been made is output to the processing unit 5, and upon receiving the signal, the processing unit 5 is set to perform difference processing. Also,
If the other party requests a difference based on the received facsimile information, the user operates the difference setting unit 4 to perform a difference process. When these settings are made, the notifying unit 8 notifies that the difference setting has been made visually (for example, display), sensory (for example, vibration) or audibly (for example, sound).

Then, the processing unit 5 reads the reply information input by the user from the memory unit 7 and transmits the reply information to the other party via the transmission / reception switching unit 1.

Therefore, as shown in FIG. 3A, the information X received from the partner is displayed but not transmitted to the partner, but only the information Y input by the user is transmitted. Then, the transmission source (recipient) who has received the information can display and view the transmitted information X and the information Y transmitted from the user together. On the other hand, FIG. 2B shows a state of transmission and reception according to the conventional example for reference. That is, in the conventional example, information transmitted from the user to the transmission source includes reception information X in addition to information Y.

Therefore, the amount of information to be transmitted and received can be significantly reduced as compared with the conventional example. In particular, when reply information including only answers or only necessary items is transmitted, the amount of information is significantly reduced, which is effective.

Next, a supplementary explanation of the processing flow will be given with reference to the flowchart of FIG. First, it is determined whether or not the signal received in step S1 is a facsimile signal.
Since this follow chart is for facsimile reception, it does not proceed to the next step unless it is a facsimile signal.

In step S2, it is determined whether or not there is identification information requesting a difference at a predetermined position of the received signal. As a result, when identification information exists, the flag f1 is set to 1, and when there is no identification information, the flag f1 is set to 0 (step S2). S3, S4), and proceed to step S5.

In step S5, when the received facsimile signal is displayed as image information, when the request for the difference is confirmed, or when the other party recognizes that the difference is supported, the user sets the difference in the difference setting section 4 to set the difference. It is determined whether the setting has been made. As a result, if there is a setting, the flag f2 is set to 1, otherwise, the flag f2 is set to 0 (steps S6 and S7), and the process proceeds to step S8. Here, there is no problem even if steps S2 to S4 and steps S5 to S7 are interchanged. Also,
Steps S5 to S7 may be omitted. By this omission, the trouble of setting by the user is eliminated, and it is possible to automatically cope with only the received information.

It is not necessary to complete the reception of the facsimile before executing step S8.

At step S8, the user inputs a reply to the image information of the received facsimile signal. Thereafter, at step S9, the flag f1 or the flag f is set.
It is determined whether 2 is 1 or not. This determination is to determine whether the input response is a differential response to be transmitted only or a normal transmission to be transmitted together with the received information. Transmission processing is performed in steps S10 and S11.

In this manner, whether or not to perform differential transmission is determined by the setting for differential transmission. Therefore, it is possible to determine whether to transmit only the difference or to transmit the received information + the difference information based on the conditions such as the corresponding model of the other party, and it is possible to reduce the amount of information as much as possible.

Next, as another embodiment, a terminal for transmitting a difference transmission request will be described with reference to FIG. Basically, it is the same as the embodiment of FIG. 1 except that a difference request setting unit 9 for setting a request for difference transmission and an image reading unit 10 for reading an image to be transmitted from paper or the like are provided. I have. The image reading unit 10 may read image information obtained from an image processing device or the like as data.

This terminal can be used by the side transmitting the original document in the embodiment described above. That is,
The image information to be transmitted is read by the image reading unit 10, and the read image information is stored in the memory 7 and transmitted by fax to one or more users. Then, as described above, when a reply corresponding to the request for the differential transmission is sent, it is received, and the original image and the received reply information are superimposed and displayed on the display unit 6. In this case, however, the original image and the received response information are handled as separate areas, so that only the response information or only the original image can be displayed.

As described above, whether to display in a superimposed manner or one of them is determined on the basis of information from the other party exchanged in the communication at the time of communication, or is determined by the setting of the user. . This user setting is made by the difference request setting unit 9
May be determined at the time of setting, or may be set by the input unit 6b.

When a difference request is set by the difference request setting unit 9, information indicating that the request is a difference request is superimposed on the transmission data at the time of transmission, and the transmission is performed. Thus, if the user who has received the facsimile information inputs the reply without being conscious, the difference request can be determined and only the reply information can be sent back.

That is, if a difference request is set when transmitting the original information, the device on the receiving side recognizes the difference request and transmits only the reply information. Depending on the setting, the original information transmitted and the response information received can be displayed in an overlapping manner, or only the received response information can be displayed.

[0032]

According to the present invention, only the reply information to the transmitted facsimile information can be sent back to the transmitting side when the differential communication is set, so that the amount of information to be communicated can be greatly reduced. it can. Thereby, the line usage fee and the communication time can be reduced.

Further, it can be used also as a normal facsimile machine, and furthermore, it is sufficient to hold transmission / reception information in a memory and display it on a display unit, and if necessary, connect a printer or the like. Since output can be performed on paper, miniaturization and weight reduction can be achieved, and if a wireless transmission / reception function is provided, location restrictions can be expanded without limit.
