Abstract

PURPOSE:To confirm whether or not the content of a relay command is correctly decoded by devising the equipment such that the content of a command after the reception of picture information is returned to a caller as a confirmation report. CONSTITUTION:A picture signal inputted from a line is stored once in a RAM 33 via MODEM and network control circuit(NCU) 36 and the picture signal read from the RAM 33 is fed to a recording section 38 via an interface 37 and recorded. Thus, the content of a command is returned to the caller as a confirmation report after the reception of picture information in this way. That is, when the caller sets a special designation by using a nonstandard procedure or an identification sheet and designates a turnaround polling, the content of the specific designation is decoded and the content is sent to the caller. Thus, in the case of the presence of a special designation such as a relay request, the designation is confirmed.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a facsimile machine that enables relay broadcast communication, etc., and particularly to a facsimile machine that has means for confirming whether relay instruction contents have been correctly decoded. Pause.

[Background of the Invention] Image communication devices such as cofacsimile machines are capable of automatically detecting destinations, automatically connecting and changing telephone lines, and automatically transmitting documents to each destination. A facsimile machine having a transmission destination identification function has been developed.

These facsimile machines identify the recipient and connect or change the recipient's line, so the recipient's telephone number, recipient's name, number of sheets to send, image quality, density, and other specifications are required. Uses identification sheets that can be inserted during non-standard procedures and record various information.

When an identification sheet is used, the identification sheet is sent before the document is sent, and the information on the identification sheet is read to perform processing according to the specified contents.

For example, as shown in FIG. 3, the identification sheet 10 is a sheet of paper about the size of A4, which is used in a vertical format. A notch 15 is formed at one end of the sheet 10 and is used as a sheet identification area. Identification sheet 10
A recording area 20 in which various types of information as described above can be recorded is provided at the center of the recording area 20 .

In the figure, the arrow indicates the conveyance direction of the identification sheet, and the end 11 is the end on the sheet insertion side.

In order to identify the notch 15, a pair of sensors (such as photosensors) TS1 and TS2 are arranged within the device main body with the same width as the notch 15 and the same distance from each other as the depth thereof.

Therefore, the document conveying means 1 can be constructed as shown in FIG.

In the figure, the paper fed in by the feeding roller 2 is ejected to the main body of the apparatus while being held between a pair of ejecting rollers 3 and 4. The feed roller 2 and the pair of transport rollers 3.4 have a positional relationship as shown in the figure, and a pair of detection sensors TSI.

TS2 is placed and image reading is performed below it.

By doing this, when the notch 15 exists in the sheet fed by the feeding roller 2, the pair of detection sensors TS1. The leading edge of the paper detected by TS2 is at the same timing, but when there is no notch 15, the timing is different. By determining this difference in timing, it is possible to identify whether the conveyed paper is a normal document or an identification sheet.

[Problems to be Solved by the Invention] As described above, in today's facsimile machines, the calling party uses non-standard procedures or identification sheets to request the called party to make relay requests or make special instructions such as multi-copying. can do.

However, it is not at all clear whether the called side will correctly decode and process such specifications.

For example, when a relay request is made using an identification sheet, if the called party cannot identify the 10th object on the identification sheet as the identification sheet, the information on the identification sheet 10 will be processed as mere image information, and the image information will be printed out. It ends up. On the calling side, there is no means of confirmation in such a case.

Therefore, this invention solves these conventional problems,
The purpose of the present invention is to propose a facsimile machine which is capable of confirming a special designation such as a relay request when the designation is made.

[Means for Solving the Problems] In order to solve the problem mentioned above, the present invention has a sending destination identification function that can decipher special designations specified by an identification sheet for image communication or a non-standard procedure. The facsimile apparatus is characterized in that, after receiving the image information, the specified contents can be returned to the calling party as a 6S' recognition report.

[Operation] If the calling party specifies a special designation using a non-standard procedure or identification sheet, and if the calling party specifies turnaround polling, the content of the special designation shall be changed. is decoded and its contents are sent to the calling party.

If the special designation is not correctly deciphered, the deciphered content will not be returned, so that the calling party can reliably identify that there was a problem with the receiving process on the called party.

[Embodiment] Next, an example of a facsimile machine having a transmission destination identification function according to the present invention is shown in Fig. 1 and below. This will be explained in detail.

FIG. 1 shows the communication +FN, t, in the facsimile machine 1.
31 is a CPU that manages communication control; 32 is a ROM in which various control programs are stored; and 33 is a CPU for controlling image information, image signals to be transmitted, etc. This is a RAM that stores .

The image signal read by the image reading unit 34 is sent to the RAN 133
or directly after being stored in the interface 3
5 to the modem and network control circuit (NCU) 3G. Further, the image signal manually inputted from the line is temporarily stored in the RAM 33 via this modem and the NCUa6.

The image signals read out from the RA and M2S are supplied to the recording section 38 via the interface 37 and recorded.

It is also possible to directly record the incoming image signal without storing it in the RAM 33.

The telephone number of the destination is supplied to the display unit 40 via the interface 39, and is displayed.

The operation section 41 provided in the facsimile machine is provided with a selection means (not shown) for selecting relay communication IN (including relay communication), etc. When operated, the contents are sent to the CPU 31 via the interface 42. It is captured. As a result, information (code) indicating that relay communication is possible can be inserted into a predetermined transmission procedure.

Further, the calling side can also specify turnaround polling. Turnaround polling is a polling function that allows the image information of the called side to be transmitted from the calling side to the calling side after the sending of the image information from the calling side is completed.

The turnaround polling function can be specified from the main menu.

FIG. 2 is a flowchart showing an example of a communication control procedure in a facsimile machine.0 The calling side is a middle station, and the called side is a relay station.

When a call is made from the calling side to the called side to connect the line, the called side sends a digital identification signal D in response.
Along with the NS, a non-standard function identification signal NSF is sent to the calling party IS.

When the calling side detects the transmitted digital identification signal NSF, a non-standard function setting signal NSS is sent to the called side.

When the above-mentioned relay request is processed, information indicating that the relay request should be postponed is added to the non-standard function setting signal NSS. Therefore, this information also includes information on the size of the transmitted document.

After the non-standard function setting signal NSS is sent, the calling side further sends a training check signal TCF,
In response to this, the called party sends a CF, which is a reception preparation confirmation signal.
An R signal is sent out. On the calling side, transmission of the image signal is started only after receiving this CFR signal.

The image signal includes not only the image information of the identification sheet 10 but also the image information of the original as described above. When the called side recognizes the first-transmitted identification sheet 10 among these image signals as an identification sheet, it decodes the various specified contents recorded on the identification sheet 10, and sets processing according to the contents. and enters the standby state for the specified process.

When all the image signals have been sent, an EOM signal, which is a mode change signal, is sent to the called party, and in response to this, the called party sends a message confirmation signal, M
A CF signal is sent to the calling party.

After the MCF signal is sent, the procedure returns to phase B again, and the DIS signal and NSF signal are sent to the calling party. After reading this content, the calling side sends an NSC signal, which is a non-standard function command signal, to the called side.

By receiving this NSC signal, the identification seal l-
10 is determined to be a request to return a confirmation report regarding the recognition data, and a digital command signal (NSS signal) indicating that this non-standard function has been set is sent to the calling party.

Thereafter, the above-mentioned confirmation report is developed as image information data and sent back. For example, in the case of a relay request, the confirmation report includes information such as the telephone number of the other party and the number of messages sent.

Once the confirmation report is sent, the called party will receive an identification sheet lO
First of all, you can confirm that it was recognized correctly, and in addition to this,
The specified contents recorded on the identification sheet 10 can also be confirmed at the same time. This is because if the identification sheet 10 cannot be recognized as an identification sheet, information such as the telephone number of the other party specified on the identification sheet 10 cannot be returned.

When the transmission of the confirmation report is completed, an EOP signal is sent to the calling party, and the calling party receives this EOP signal.
When receiving the OP signal, it sends the MCF signal.

Therefore, by receiving and accepting this MCF signal, the called side receives the D CN which is a command signal for disconnecting the line.
By sending No. 18, the line is disconnected.

After the line is disconnected, the called party ([1 (relay station) to the other party (
The received image information is transmitted to one or more receiving stations.

In the above example, an identification sheet is used to specify a relay request, but the same operation and effect can be obtained even if this specification is made during a non-standard procedure.

The confirmation report may be formatted and stored in a memory, and only necessary information may be added to the confirmation report and sent as a confirmation report.

[Effects of the Invention] As explained above, in the present invention, when specified by the calling side, the called side is configured to return a predetermined confirmation report to the calling side.

This feature allows the called party to extremely easily determine whether or not the called party has correctly recognized a special designation from the calling party.

If the identification sheet cannot be recognized correctly,
Since it is only necessary to retransmit the same content, incomplete communication during relay communication can almost certainly be eliminated, and facsimile communication with higher reliability than before can be realized.

This kind of reply can be achieved very easily by using the turnaround polling function, so adding this function does not make any difference in cost.
