Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a communication partner confirmation method for a facsimile machine, which enables automatic confirmation of the destination party using a specific mark placed on a transmission document when a called station sends an absentee call.

Facsimile devices use a dedicated transmission line as well as a general telephone exchange network, which enables transmission and reception over a wider range. When performing facsimile communication using this general telephone exchange network, control signals are exchanged between each other such as confirming the other party before sending and receiving, and control signals such as transmission completion are also exchanged after the manuscript is completed to ensure security. disconnect the line. As such a transmission control procedure, CCITT (Commission International Telegraph and Telephone Information)
There are some things shown in proposal T30. FIG. 1 shows an example of the binary procedure in which the calling party receives and the called party transmits. In this example, when a telephone dials from station B, the switching network selects station C and makes the call. At this time, if it is an automatic answering station, a line is automatically established (DC loop closure) based on the condition that the facsimile device is on standby.
CED (Called) is a tone signal indicating this.
Station Identification). At this stage, line connection has been established. After this, the called station C receives an ID signal (Initial
Identification). This ID signal has
DIS (indicating that the called device has standard CCITT functionality) and CSI (specific signals to identify the called station)
There are different types. When calling station B receives this ID signal, calling station B sends a transmission command requesting called station C to transmit. This transmission command has a DTC
There are types such as (response command for standard functions indicated by DIS signal) and CIG (calling station ID signal). After that, the transmitter sends a reception command, which is a function setup command, to the receiver, and also performs training for the modem and sends and receives a training check code. A CFR signal is sent, and in response, a facsimile signal of the original (message) is transmitted from the called station. When the transmission of this document is completed, a post message command indicating the end of the text and a post message response are exchanged, and finally, the called station C issues a line disconnection command.

As mentioned above, before sending the manuscript (main text), DIS
The called station and the calling station are confirmed using a specific signal given to that station by the caller or CIG, and then facsimile signals are sent and received. However, these signals are for confirming the called station and the calling station, and there is no concept of confirming the other party depending on the transmitted document. In other words, how to use CIG in the callee's absentee transmission is a problem for the facsimile device. In the past, for example, there was a method of setting a transmitter so that the called station would start transmitting after confirming a specific ID signal of the calling station. However, in this case, although it is possible to check for a specific calling station, if there are multiple documents with different transmission destinations, it is not possible to automatically check the destination station and send the documents.

The present invention has been made with these points in mind. When a called party sends an absentee call, a specific mark is placed on the transmission document according to the destination, and this mark is converted into an electrical signal to be transmitted to the other party. The purpose of this invention is to provide a partner confirmation method for a facsimile machine, which is used to check the ID signal of the station, and automatically confirms the partner station for each document and transmits the document.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows an example of a system configuration of a facsimile device to which the present invention is applied.
The stations 1 to 5 of D and E are exchange-connected via a telephone exchange network 6. For example, if A station 1 and B station 2 call C station 3 at different times, and C station 3 automatically responds, C station 3 will send a manuscript to A station 1,
It is necessary to set the original to the B station 2 on the same transmitter and transmit it.

In the present invention, the document to be set is provided with a collation mark field 7 as shown in FIG. 3. This collation mark field 7 is provided at the top of the main text of the manuscript (in front in the sub-scanning direction), and is divided into a plurality of parts in the main scanning direction, for example, and each of the divided parts 7A, 7B, 7C, 7D, . . .
. . corresponds to each partner station. For example, if the transmission destination is station B 2, mark 8 such as a black line is written in portion 7B. Similarly, a mark is applied to the portion 7A of the document to be sent to the A station 1. Here, each station is distinguished by its position in the main scanning direction, but the invention is not limited to this; for example, the shape of the mark may be changed at the same position.

By setting the originals like this, an electrical signal is generated according to each mark, and this signal is sent to the other station's ID.
It checks the signal, identifies the destination, and transmits.

Examples of the configuration of a transmitter that specifically performs this operation are shown in FIGS. 4 and 5. FIG. 4 shows the document reading part, in which a paper feed tray 10 guides the transmitted document 9.
An automatic paper feeder 11 is provided at the end of the automatic paper feeder 11, and paper feed rollers 12, 1 are installed at predetermined intervals on the take-out side of the automatic paper feeder 11.
3 is provided, and a stacker 14 is provided below this paper feed roller 13. On the other hand, light sources 15 and 16 such as fluorescent lamps are provided near the supply rollers 12 and 13, and an optical system 17 that takes out the light reflected by the original 9 from the light sources 15 and 16, and an image that detects the light from this optical system 17. A scanner 18 such as a sensor is provided.

That is, the transmission document 9 is sent out by an automatic paper feeder 11, guided by paper feed rollers 12 and 13, and led to a stacker 14. When the paper passes between the feeding rollers 12 and 13, it is irradiated by light sources 15 and 16, and the reflected light is guided to a scanner 18 through an optical system 17 to read the original. At this time, the collation mark column 7 is first read, and then the main text is read.

FIG. 5 shows the overall configuration of the transmitter. The output signal of the scanner 18 described above is guided to an image signal amplifier 19 that performs binarization processing and contrast adjustment of the signal, and the output signal is sent to a band compression coder 20. and is guided to the reference mark detector 21. Band compression coder 20 performs band compression digitally, and its output signal is guided to high-speed code modulator 22, where it is sent out to the line via network control unit 23 as a signal suitable for the transmission line. Further, the verification mark detector 21 has a function of sending out an electrical signal corresponding to the mark position in the aforementioned verification mark column 7, and the signal is guided to the ID code converter 24. This ID code converter 24 has a function of converting the electrical signals extracted corresponding to the positions of the collation mark field 7 into ID codes of each partner station. Also 2
5 and 26 are modulators and demodulators for control signals, respectively, and a network control unit 23 that performs switching between telephone and facsimile equipment, matching with lines, etc.
The demodulator 26 demodulates the control signal from the other station, and its output signal is guided to the control unit 27 and to the ID code detector 28. This ID code detector 28 detects the ID code sent from the other station, and this detected signal is guided to the matching circuit 9. This collation circuit 29 has a function of collating the output signal from the ID code converter 24 and the output signal of the ID code detector 28, and determining whether or not they match. Although not shown, the control unit 27 controls the sub-scanning motor, and operates the sub-scanning motor again depending on the matching output of the matching circuit 29, and also modulates a signal indicating the state of this control. The signal is modulated by the receiver 25 and sent to the partner station.

That is, at the called station (C station 3 in FIG. 2), A station 1 and B station
A transmission document 9 addressed to station 2 is attached. In this state, for example, there is a call from station B 2, and according to the procedure shown in FIG. 1, CED signals are exchanged and a line is established. And initial ID from C station 3
A signal is sent, and in response to this, station B 2 issues a transmission command. This transmission command is executed in a frame structure as shown in FIG. In other words, the flag, address part,
It consists of a control section, a facsimile control section, a facsimile signal section, an ID signal section, a signal error detection section, and a flag, each of which has the required number of bits. C station 3, which received this transmission command, demodulates it with demodulator 26,
control unit 27. As a result, the control unit 27 starts the sub-scanning motor and sends the original 9 to be sent.
is sent until the verification mark field 7 reaches the reading position.
The mark 8 in the verification mark field 7 is read by the scanner 18, amplified by the image signal amplifier 19, and detected by the verification mark detection circuit 21. This signal is converted into an ID code by the ID code converter 24, and on the other hand, the ID signal included in the transmission command (FIG. 6) is extracted from the B station 2 through the demodulator 26 and the ID code detector 28, and the verification circuit 29 Check these two ID signals.
If both signals match, the control unit 27 sends a reception command to the B station 2, and the station becomes ready for transmission. If they do not match, the receiving command is stopped or a special signal indicating that the matching does not match is sent.

If there is a match, the modem will undergo training, etc., receive the CFR signal, and then proceed to normal document transmission.

In addition, when sending a matching mismatch signal in response to a matching mismatch, the type of this signal is changed, for example: 1 to inquire about the document received by B station, 2 to send the document although there is a document on the paper feed tray, and B station to the paper feed tray. This is convenient because it is possible to distinguish and return documents, such as those that have not been received.

In the embodiment, an example using a digital band compressed facsimile signal has been described, but the present invention is not limited to this.

As described above, according to the present invention, the transmission destination is detected by the verification mark on the transmission document, and confirmation with the other station is automatically performed by a signal corresponding to this mark. This eliminates erroneous transmissions when the called station sends calls to absentee persons, and even if there are multiple documents to be sent to different destinations, the destination station to be sent to is automatically identified and sent, making the system easier. Very suitable for automation. Further, according to the present invention, since the facsimile apparatus is configured to perform checking between the mark on the document and the receiving station of the other party, there is an advantage that functions can be easily added.
