Abstract

PURPOSE:To enable an operator to carry out the communicating operation of the turn-around polling as necessary without performing a setting operation for each transmission as long as the prescribed registration is carried out to each opposite party. CONSTITUTION:An individual address key 6a and the abbreviated dialing are first registered. At the same time, the facsimile number of the opposite party and the necessity or unnecessity of the receiving operation carried out after transmission of an image are stored in a system memory 7. When an original is set to a scanner 1 and an outgoing destination is set, the image is transmitted in a prescribed transmitting procedure. If the reception of the image is required by the opposite party, the called side is switched to the transmitting side by a known switch means. In other words, the calling side requests the information of the end of transmission and the re-execution of the transmission control and then carries out an image transmission request. Thus the called side starts the transmission and the calling side receives the picture information. In such a constitution, the communicating operation of the turn-around polling can be carried out in a correct way as long as the necessity or unnecessity of the receiving operation carried out after transmission of an image is previously shown.

2. Description of the Related Art Currently, CCITT is used for ordinary telephone lines.
A G3 standard facsimile machine conforming to the above recommendation is generally used. Such a facsimile machine is described in Recommendation T.W. According to 30, the transmission control procedure is executed. This Recommendation T. In No. 30, the transmission control procedure of the turnaround polling in which after the image is transmitted from the calling side facsimile device and subsequently the image is received from the called side is defined.

This turnaround polling communication operation is used as follows, for example, when a user receives a document information service from a predetermined center.

That is, in this case, a facsimile machine connected to the computer is installed on the center side. On the user side, for example, a mark designating request information is entered on a predetermined mark sheet. Then, the mark sheet image is transmitted to the center side by the facsimile device. On the center side, the facsimile device receives the mark sheet image, and the computer determines the request information. Then, the corresponding document image is returned to the user side.

According to such a turnaround polling communication operation, information can be efficiently transmitted and received by one communication.

In order to execute the above-mentioned communication operation, the calling side facsimile apparatus needs to execute a certain transmission control procedure for shifting to turnaround polling after transmitting an image. Therefore, when making a call, the operator needs to perform a setting operation for causing the facsimile device to execute the transmission control.

However, if the operator is not accustomed to the operation of the facsimile apparatus or does not understand the meaning of the communication operation of the turnaround polling, the setting operation cannot be properly executed when necessary. It was

Conventionally, when the center which provides the document information service does not shift to the transmission control procedure of the turnaround polling after receiving the mark sheet image from the user, the communication is temporarily terminated, and then the center. From the user side to the user side, a predetermined document image is transmitted.

Therefore, in this case, the efficiency of communication is reduced, and the center side has to identify the facsimile number of the calling side facsimile device or make a new call, which complicates the operation. .

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a facsimile apparatus according to an embodiment of the present invention. In the figure, a scanner 1 reads a document image, and a plotter 2 records and outputs a received image. The encoding / decoding unit 3 compresses the image information to be transmitted by various encoding methods, while decoding the received image information to restore the original image information. The modem 4 transmits / receives a procedure signal for transmission control and image information by a known procedure of G3 facsimile.

The network control device 5 is connected to a telephone line and performs predetermined line control when making or receiving a call. The operation display unit 6 is for displaying various information such as the operating state of the device as the operator performs various operations. This operation display unit 6
An individual destination key 6a and a numeric keypad 6b are provided in the. The individual destination key 6a is a plurality of operation keys, and if the callee is registered in advance in each key, the call can be sent to the callee with one key operation. This calling operation is generally called one-touch dial. The ten-key pad 6b is used for inputting a facsimile number or a speed dial number of a calling party.

The system memory 7 stores registration information of the individual destination key 6a and the speed dial. The system control unit 8 is a microphone computer that monitors and controls the above-mentioned units, and the system bus 9 is a signal line through which the above-mentioned units exchange various control signals and data with each other.

With the above-mentioned configuration, the facsimile apparatus of this embodiment has a function of transmitting the image, transmitting the image, subsequently executing the turnaround polling transmission control procedure, and receiving the image from the other party. .

When using this facsimile apparatus, the operator first executes the registration process of the individual destination key 6a and the speed dial in a predetermined operation procedure. In this registration process, for each key of the individual destination key 6a and each number of the speed dial, the destination facsimile number to be transmitted and the necessity of the receiving operation after image transmission are registered. The reception operation after image transmission is an operation of transmitting an image and subsequently receiving the image by a transmission control procedure of turnaround polling. This receiving operation is performed, for example, when the other party is the center that performs the document information service described above.
Register as needed.

By this registration processing, as shown in FIG.
Corresponding information about each key of the individual destination key 6a and each abbreviated number, the facsimile number of the other party, and the necessity of the receiving operation after image transmission is registered. This registration information is stored and stored in the system memory 7.

Next, when transmitting an image, the operator
As shown in FIG. 3, the transmission original is set on the scanner 1 (process 101), and the destination address is set by operating the individual destination key 6a or inputting the abbreviated number with the ten keys 6b (process 102).

The facsimile device calls the set destination (process 103) and transmits the document image according to a predetermined transmission control procedure (process 104).

When the image transmission is completed, it is judged whether or not it is necessary to receive the image from the other party based on the registration information (process 105). Here, if it is registered that image reception is not necessary (N in process 105), communication is ended after predetermined transmission control.

FIG. 4A shows an example of the transmission control procedure in this case. That is, when the facsimile apparatus of this embodiment makes a call to the other party, the called party receives the CED signal, N
The SF signal and the DIS signal are sequentially transmitted. After receiving these signals, the calling side sends NSS signals and TCF signals. The called party receives these signals and performs modem training. If the training is successful, the CFR signal is sent. The calling side then reads the transmission document and transmits the image information. Now, assuming that the transmitted document is only one page, the EOP signal is transmitted when the image information has been transmitted. The EOP signal notifies the called side that the image information to be transmitted has ended.

When the called side receives the image information without any error, it receives the EOP signal and then sends the MCF signal. When the calling side confirms the MCF signal, the DCN
It sends a signal, disconnects the line, and terminates communication.

Next, when it is registered that the image reception is necessary from the other party (Y in step 105), a known switching procedure for switching the called side to the transmitting side is executed.

FIG. 4B shows the transmission control procedure in this case. That is, the calling side sends the EOM signal when the transmission of the image information is completed. The EOM signal notifies the callee of the end of transmission of one page of image information, and requests re-execution of transmission control.

When the called party receives the EOM signal, the MC
Send the F signal. Then, the NSF signal and the DIS signal are transmitted. When the caller receives those signals, it
Send the SC signal. The NSC signal requests the called side to send an image.

Now, it is assumed that the called side has an image transmitting function like the center for providing the document information service described above. In this case, when the called side receives the NSC signal, it switches to the transmitting side of the image information (process 106).

As a result, the called side sends the NSS signal and the TCF signal next. The calling party receives these signals, performs modem training, and, if the training is successful, sends out a CFR signal. Called party is CFR
When the signal is received, the image information is transmitted. The calling side receives the transmitted image information (process 107).

When the transmission of the image information of the called side and the reception of the image information of the calling side are completed, the two sides complete the communication operation after the transmission control procedure similar to that shown in FIG.

As described above, in this embodiment, the necessity of the receiving operation after image transmission is registered in advance with the destination facsimile number in the individual destination key 6a and the speed dial, and the individual destination key 6a is registered. Or when making a call with a shortened number,
When the reception operation is registered as being necessary, the turnaround polling communication operation is executed. As a result, the operator does not have to make setting operations for each call, but can turn around the
The polling communication operation can be executed correctly.

Next, another embodiment of the present invention will be described.

That is, the receiving operation after image transmission is executed, for example, when the above-mentioned document information service is received. In such a service, it is necessary to fill in a prescribed mark sheet with necessary items and transmit the mark sheet image. Become. Therefore, in such a case, the image M of a fixed pattern may be recorded or printed in advance at the specified position of the mark sheet to be used.

Only when the receiving operation is required after the image transmission as described above, the operator sets the transmission original to which the image M of a fixed pattern is added, and performs the transmission operation in the same operation procedure as the above-mentioned embodiment.

In accordance with the operator's operation, the facsimile machine calls the other party and transmits an image in the same operation as in FIG. However, in this embodiment, when the image transmission ends,
As shown in FIG. 6, the image information at the specified position in the transmission image is checked (process 108). Then, it is determined whether or not the image information is the image M of a fixed pattern (Process 1
09).

Here, if there is no image M having a fixed pattern in the image information at the specified position (N in step 109), the communication is ended as it is. On the other hand, when there is a fixed pattern of image M (Y in processing 109), as described with reference to FIG. 3, a predetermined switching procedure for switching the called side to the transmitting side is executed to receive the image from the other party. (Go to processing 106).

As described above, in the present embodiment, the turnaround polling is executed when the transmission image includes the image M having a predetermined pattern.

In general, the turnaround polling communication operation is executed when a specific original image is transmitted to a specific destination. Therefore, by recording the image M of a certain pattern on such a specific document in advance, the operator does not have to make a setting operation at the time of call-out, as in the case of the above-described embodiment, without making a turn-around operation.
The polling communication operation can be correctly executed as needed.

In the above embodiment, the fixed pattern image M is arranged at a fixed upper left position in the image of one page, but it may be arranged at another fixed position or at an arbitrary position. Good.

In the present embodiment, the operator performs the transmission operation in the same operation procedure regardless of whether the reception operation is executed after the image transmission.

In accordance with the operator's operation, the facsimile machine calls the other party and transmits an image by the same operation as in FIG. However, in this embodiment, the called party responds by sending the NSF.
When sending a signal, if it is desired to continue sending an image after receiving an image, the NSF signal is set with identification information indicating the desired transmission and sent. It is, for example, the center that provides the above-mentioned document information service that sends such a transmission request.

After the image transmission is completed, the facsimile machine checks the reception information of the NSF signal as shown in FIG. 7 (process 110). Then, it is determined whether or not the identification information desired to be transmitted is set in the received information (process 111). Here, if the identification information does not exist (N in process 111), the communication ends as it is. On the other hand, if there is identification information desired to be transmitted (Y in process 111), the process proceeds to
As described above, a predetermined switching procedure for switching the called side to the transmitting side is executed, and the image is received from the other party (to step 106).

As described above, in this embodiment, the called side sends the identification information desired to be sent to the calling side by the procedure signal when the image should be sent. As a result, similarly to the above-described embodiment, the operator can correctly execute the turnaround polling communication operation as necessary without making a setting operation for each call.

In the above embodiment, the called side sends the transmission request to the calling side by the NSF signal, but other signals such as DIS signal may be used. Further, the calling side sends the NSC signal when the turnaround polling is executed, but a DTC signal may be used.
