Abstract

PURPOSE:To certainly recognize the telephone number of a transmitting side on a receiving side by dividing a data storing section into two telephone number storing sections and changing the content to be set in a transmitting terminal identification signal by means of a CPU after discriminating the presence/ absence of a nonstandard function signal in signals transmitted from the receiving side. CONSTITUTION:When a call signal arrives at a called station after dialing at a calling station, the called station side sends a called station identification(CED) signal followed by a non-standard function(NSF) signal. called terminal identification(CSI) signal, and digital identification(DIS) signal. Upon receiving the DIS signal, the the calling station starts to send a transmitting terminal identification(TSI) signal. When the NSF signal is received, the telephone number B to be set in a TSI frame is the telephone number registered in the telephone number storing section B20 of a data storing section 20. Since the telephone number is the telephone number itself including the toll number, the receiving side can recognize the telephone number of the transmitting side.

Description

[Detailed description of the invention] [Industrial application field]

In this invention, when communicating with a facsimile device, the sending side determines the presence or absence of a non-standard function signal sent from the receiving side, and selects one of two types of telephone numbers set in the data storage unit. The present invention relates to a facsimile apparatus which sends out a transmitting terminal identification signal as a transmitting terminal identification signal.

[Conventional technology]

FIG. 5 is a block diagram showing the configuration of a conventional facsimile machine. In the figure, 11 is a reading unit that converts image data of a document into an electrical signal, and 12 is an encoding unit that encodes image data from the reading unit 11. 15 is a communication control unit for performing communication; 16 is a communication control unit that modulates the image data from the communication control unit 15 and sends it to the NCU (814 control unit) unit 17 during communication; A modem 18 is a telephone line for demodulating the signal. Further, 14 is a decoding unit for inputting the signal demodulated by the modem 16 via the communication control unit 15 and converting the encoded image data into image data, and 13 is for recording the image data on recording paper. A recording unit 19 is a central processing unit (hereinafter referred to as CPU), 20 is a data storage unit for storing telephone number 1 communication results, etc., and 20a is a telephone number storage unit for registering your own telephone number. It is A. For example, telephone numbers as shown in Table 1 below are registered in the telephone number storage unit Δ20a, but if you have a contract with the facsimile network of Nippon Telegraph and Telephone Corporation (hereinafter referred to as NTT), for example, A number such as telephone number T1 is registered, and when registering a normal telephone number itself, a number such as telephone number T2 is registered. <Table 1> Figure 6 shows an example of the communication procedure in CCITT Recommendation T.30, and Figure 7 shows the control flow when transmitting the transmitting terminal identification signal (TS+ signal) during the communication procedure in Figure 6. . FIG. 8 is a pronk diagram showing an example of the configuration of a communication network using facsimile machines. In the figure, ■ indicates a center station, and 2 transfers data from the center station 1 to terminal stations 2a and 2b. Transfer stations A and 3 for transferring to terminal stations 2c and 3 are transfer stations B for transferring to terminal stations 3a, 3b and 3c, similar to transfer station A2. Further, FIG. 9 is an example of a collection form when the transfer results of transfer station A2 and transfer station B3 are collected to center station 1, and the arrow in the figure indicates the direction of call origination. Next, the operation will be explained. In the example of the communication procedure shown in FIG. 6, when a paging signal arrives at the called station by dialing from the calling station, the called station receives
D signal), followed by a non-standard function signal (NSF signal), a called terminal identification signal (C3I signal), and a digital identification signal (DI313). NSF signal and C8I signal comply with CCTTT Recommendation 1.3
0, this is an optional signal, but most of the facsimile machines η generally sold on the market are equipped with a transmission/reception stage for the NSF signal and the C3I signal. The transmitting side receives the NSF, C3I, and DIS signal, and sends a non-standard function setting signal (NSS signal) and a transmitting terminal identification signal ('r'sI) to the receiving side, which is the called station.
Signal) 1 Digital command signal (DC3C3I is transmitted. In addition, the TS! signal is a signal that transmits the telephone number of the transmitter according to a predetermined format. NSSSS
If the manufacturer of the facsimile is different from that of the facsimile on the Shin Aishin side, the facsimile will not normally be sent. Flowchart for sending this "f" sI times signal [・
For example, as shown in FIG. 7, after detecting the DIS signal in step STI, the telephone number of the own station is set in the 'rSI signal in order to send out the TSL signal in step ST2, and the TSI signal is transmitted in step ST3. Move on to transmission control. The telephone number A set in the TSI signal is, for example, as shown in Table 1 above. In this Table 1, telephone number TI
is the setting formant telephone number when contracting with the NTF facsimile network, financial information system, etc. ``2 is an example when registering the entire telephone number of the own office including the area code. Next, In step ST4, data is set in the DCS Shingetsu, in step ST5 the DC3C3I is transmitted, and then in step ST6 a training check signal (TCP signal) is sent.
Send. After transmitting the TCF signal from the calling station to the called station, as shown in Figure 6, the reception rate (M 6% acknowledgment signal (
After transmitting the image signal from the calling station to the called station, the calling station sends a procedure end signal (EOP signal), and the called station sends a message confirmation signal (MCF signal) to the calling station. and finally a line disconnection signal (DCN signal) from the calling station.
to the called station. Next, the route for actual transmission will be explained with reference to FIG. The telephone number is registered in the telephone number storage section A20a in the data storage section 20. The data storage unit 20 generally uses, for example, a nonvolatile memory. When transmitting the TS+ signal, the CPU 19 uses the data storage unit 2.
The telephone number data is read from 0, configured into a transmission form of a TS ■ signal, and outputted from the communication control section 15 to the modem 16. The TSI signal modulated by the modem 16 is
It is sent to the telephone line 18 via the U section 17. In the example of the facsimile communication network shown in FIG.

The telephone number information of
The SI signal is transmitted to the transfer station. The transfer station A2 and the transfer station B3 temporarily store the image data transmitted from the center station 1, and then transfer the image data to the respective terminal stations 2a and 2.
The data is sequentially transmitted to ports b, 2c, 3a, 3b, and 3c. The results of communications to the terminal stations can be known only at transfer station A2 and transfer station B3. It is necessary for the center station 1 to know whether the data transmitted by the center station 1 has been transmitted to all terminal stations, and this method is carried out, for example, as shown in FIG. 9. The center station 1 polls the transfer station and receives the transfer results from the transfer station to the center station 1. In FIG. 9, the center station 1 polls the transfer stations A2 and B3, respectively, and the center station 1 polls the transfer stations A2, . This means that the transfer result by the transfer station B3 can be known. This is because if center station L is subscribed to a facsimile network, for example, telephone number data such as telephone number T1 in Table 1 is registered, so center station L sends a TSI signal to the transfer station with the telephone number data. This is because the transfer station cannot know the correct telephone number of the center station 1 because it sends out the TI, and therefore cannot make a call to the center station 1 from the transfer station. In the standard procedure of CCITT Recommendation T.30, there is no procedure for instructing transfer, so the communication procedure between the center station and the transfer station in the example shown in Fig. 8 is based on the option signals 1' and 30 in Fig. 6. Needless to say, this is done by certain NSF and NSS signals. [Problems to be Solved by the Invention] Conventional facsimile machines are configured as described above, so in order for the center station to know the communication results of the transfer station, the center station needs to poll the transfer station. was there. However, the more terminal stations there are, the more difficult it is to predict the time at which the transfer station will finish all communications with the terminal stations.It is also extremely difficult to set the timing for polling from the center station, and it is difficult to determine when the set time is appropriate. It can be said that there is no possibility that it will take time. Also, if one transfer station receives data from multiple center stations and then transfers it to the terminal station, the transfer station will have multiple transfer result data, and the center station will send out the transfer result data by polling. There were problems such as the process being extremely complicated. This invention was made in order to solve the above-mentioned problems, and the transmission of the transfer result data from the transfer station to the center station is performed from the transfer station at the stage when the transfer station has finished transmitting to the terminal station. This allows the center station to know the transfer results very efficiently, and even if the transfer station has multiple transfer result data, it is possible to send the transfer result data to each center station with extremely simple processing. The object of the present invention is to obtain a facsimile device capable of transmitting data.

[Means to solve the problem]

The facsimile device according to the present invention includes a data storage unit that registers the telephone number of its own office in two formats, and a data storage unit that records the telephone number of its own office in two formats, and a non-standard function signal that determines the presence or absence of a non-standard function signal in a signal sent from a receiving side. The device is equipped with a central processing unit that determines whether the manufacturer code inside is the company code or not and changes the content set in the transmitting terminal identification signal.

[For use]

If the central processing unit in this invention does not detect the 'non-standard function signal sent from the receiving side or if the manufacturer code included in the non-standard function signal is not the company's own, If the function is activated or if it is detected that the manufacturer code included in the non-standard function signal belongs to the company, it sends out a transmitting terminal identification signal with an accurate telephone number and lets the receiving party know the transmitting party's code. Recognize the phone number itself.

A modem 18 is a telephone line for modulating the image data from the communication control section 15 and sending it to the NCU section 17, and for demodulating the signal from the NCU section when receiving. In addition, 14 is a model I, 16 is a decoding unit for inputting (Ii Ml) signals manually through a communication control unit 15 and converting encoded image data into image data, and 13 is a decoding unit for recording image data. Recording section that records on paper, 19 is cp
Numerals 20 and 20 are data storage sections for storing telephone number communication results, etc., and 20a and 20b are telephone number storage sections which are part of the data storage section 20 and are used to register one's own telephone number. Among these, the telephone number storage section 20a stores a number, such as telephone number T1 in Table 1, for number registration when contracting with the NTT facsimile network or the like. Further, the telephone number storage section 20b is a telephone number storage section in which a normal telephone number is registered, and for example, a number such as the telephone number T2 in Table 1 is registered. FIG. 2 shows a control flow when transmitting a TSI signal during a communication procedure in accordance with CCITT Recommendation T.30 in the present invention. Further, FIG. 3 shows transfer station A2. Transfer station B3 to center station 1
This is an example of the transmission format of the transfer result to , and the arrow in the figure indicates the direction of the call. Next, the operation will be explained. In the example of the communication procedure shown in FIG. 6, when a calling signal arrives at the called station by dialing from the calling station, the called station sends a CED signal and continues to use NSF. ,C3I,
D[Send signal. The sending side, which is the calling station, receives the NSF from the receiving side, which is the called station.
, C3I, upon receiving the Dis signal, NSS, TSI,
Moving on to the DC3C10 transmission, the setting of the TS [signal in this invention is as shown in the flowchart shown in FIG. 2, for example. In this FIG. 2, the calling station receives DI in step 5Ttt.
When the S signal is received, the process moves to transmitting the TSI signal, but the telephone number set in the TSr frame in step 5T12 is N.
It is determined whether or not an SF signal has been received, and the route is divided into two routes. If an NSF signal is received, T is selected in step 5T13.
The telephone number B set in the SI frame is the telephone number registered in the telephone number storage section B20b of the data storage section 20 in FIG. 1, and its contents are, for example, the telephone number T2 in Table 1.
It is as shown in . Since the telephone number T2 is the telephone number itself including the area code, the receiving party can recognize the transmitting party's telephone number. In FIG. 2, if the calling station does not receive the N S ri' signal due to communication via the NTT facsimile network, etc., the process moves to step 5T14, and the telephone number A set in the TSI signal is telephone number storage section A of the data storage section 20 of
This is a telephone number registered in 20a, and its contents are, for example, as shown in telephone number Tl in Table 1. Telephone number TI allows smooth communication with the NTT facsimile network, etc. Even if the receiving side is a facsimile machine that does not send out NSF signals, the telephone number T2 will be set in the TSl signal and the TSI signal will be sent out in step 5T15, but there will be no problem. In FIG. 2, the control flow after setting the telephone number in the TSI signal at step 5T13 is from step 5T16 to step 5.
The flow indicated by T19 is steps ST3 to ST6 in FIG.
is exactly the same as , and avoids duplicate explanations. Furthermore, the signal transmission path in the block diagram from the data storage section 20 in FIG. 1 is completely the same as in the conventional example, and therefore the explanation thereof will be omitted. According to the TSI signal sending method according to the present invention, for example, in the case of the facsimile communication network shown in FIG. 8, transfer station A2. Since the transfer station B3 can recognize that the content of the TSI signal sent from the center station 1 is the telephone number of the center station 1,
, 2c and B group terminal stations 3a, 3b, and 3c can be easily sent back to the center station 1 from the transfer stations A and B. As a result, as shown in Fig. 3, calls can be made from transfer station A2 and transfer station B3 to center station l, so that confirmation of the transfer result at center station l can be made from the conventional center station 1 in Fig. 9. It is more efficient than the polling method. Note that in the above embodiment, the NS sent from the receiving side
The contents of the telephone number set in the TSr signal were set in different formats depending on the presence or absence of the F signal, but for example, as shown in Figure 4, by looking at the contents of the NSF signal in more detail, you can determine whether or not your company's NSF signal was received. It may also be determined, and the same effect as in the above embodiment can be achieved. However, in FIG. 4, when the calling station receives the NSF signal in step 5T12, it transmits the NSF signal in step 5T20.
If the manufacturer code of the signal is not your company's code, proceed to step 5T14; if it is your company's code, proceed to step 5T1.
3, set telephone number B in the TSI signal, transmit the TSI signal in step 5T16, and set telephone number B in step 5T17.
Data is set in the O3 signal, and in step S'r19, the TCF signal is transmitted from the calling station to the called station.

【Effect of the invention】

According to this invention, as described in ``2'', the data storage section is
It is divided into a phone number storage unit that is compatible with T-Fax network, financial information system, etc. and a phone number storage unit that registers the actual phone number. Or, since the CPU is configured to determine the presence or absence of an in-house non-standard function signal and change the contents set in the sending terminal identification signal using the CPU, it is necessary to ensure that the receiving side knows the sender's telephone number using a facsimile communication network, etc. It has the effect of being very effective in certain situations.
