Abstract

PURPOSE:To prevent erroneous or troublesome facsimile by detecting an identification signal transmitted from the station of a communicating party before staring the exchange of image information, and starting the exchange after the contents are confirmed by a display means. CONSTITUTION:After a transmitting original is set to a read part 110, the communicating party is called by a telephone set 102, and a signal such as a call incoming station identification CED signal, etc., from the communicating party is received at a MODEM 104 and analyzed by a procedure control part 105. Further, a user identification(ID)signal is detected from the signal by an ID detection part 107, passed through a whole control part 112 and displayed at an ID display part 108. When the desired communicating party is confirmed by observing the communicating party ID displayed at the display part 108, the start button of an operation part 109 is pushed down to start the exchange of the image information. Thus, the erroneous facsimile or the troublesome facsimile can be prevented.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to facsimile machines, and more particularly to a facsimile machine capable of confirming a communication partner before communicating image information.

0002

2. Description of the Related Art In recent years, facsimile machines have become widespread, and are now being used not only in businesses but also in homes. Regarding this facsimile machine, CCITT Recommendation T. 30
The communication procedures are specified in detail in the Recommendation, and most facsimile machines comply with this recommendation. However, with the spread of such devices, junk faxes such as so-called direct mail, prank faxes, and mistaken faxes have occurred. For this reason, conventionally, prior to facsimile communication, two parties had to make a phone call to confirm the identity of the other party, and then facsimile communication was carried out.

0003

The above-mentioned conventional techniques are good when both are operated manually, but when one is operated automatically, the following problems occur. In other words, if the other party sends an automatic call, even if you receive a call, the other party will not send you a CCIT.
T RecommendationT. The only thing I can hear is the CNG signal (calling tone) determined by 30, and even though I don't know who the other party is, I end up having no choice but to receive the fax. Furthermore, if the other party is using automatic reception, only a CED signal (called station identification signal) can be heard from the other party, and the facsimile is sent without knowing whether the other party is actually the desired one.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to make it possible to confirm the other party before starting the transmission and reception of image information in facsimile communication, and to start the transmission and reception of image information by confirming the other party and then performing the start operation. The goal is to be able to get started.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides means for detecting a partner station identification signal sent from the other party, and displaying the content of the partner station identification signal detected by the detection means. A display means for starting image information and a start means for starting transmission and reception of image information are provided.

[0006]

[Operation] The partner station identification signal detection means detects the identification signal sent from the other party, and displays the contents of the detected signal on the display means. Then, the user checks the partner station displayed on the display means, and if it is the desired partner, the start means starts transmitting and receiving the image information.

The operation at the time of transmission will be explained using FIGS. 1, 2, and 3.

At the time of transmission, first connect the CML relay 201 and switch 205 to the b side, set the transmission original in the reading section 110, and then use the telephone 102 to make a call to the other party. When the other party receives it, the other party will receive CED30.
1. Each signal of NSF302, CSI303, and DIS304 is sent, and the telephone 102 receives "Pihyororo".
I hear a sound. Normally, at this stage, line 101
is connected only to the telephone 102, so signals such as the CED 301 from the other party are sent only to the telephone 102. In the present invention, the modem 104 receives signals such as the CED 301 from the other party via the pickup circuit 204, and the procedure control unit 105 analyzes these signals. Furthermore, the ID detection unit 107 detects I from among these signals.
The D signal is detected, and the detected ID is displayed on the ID display section 108 via the overall control section 112. The ID signal is generated by converting the telephone number, name, etc. of the own station into an ASCII code, for example, in the ID generation unit 113, and converting it into CSI 303 or TS of the procedure signal.
It is inserted into an area provided in the I306, NSF302, or NSS305 and sent to the other party. Therefore, the transmitting station detects the telephone number of the receiving station included in the CSI 303 or the name of the receiving station inserted in a specific area in the NSF 302. The receiving station is NSF302
, CSI 303, and DIS 304 are not sent from the transmitting station, these signals are repeatedly transmitted for a predetermined period of time. The transmitting station is ID display section 1
08, and if it is the desired partner, press the start button on the operation unit 109. Then, the CML relay 201 and switch 205 are connected to the a side, and the transmitting stations are NSS305, TSI306, and DCS.
Following each signal of 307, TCF 308 is transmitted. If the receiving station successfully receives this TCF308, the CFR
After receiving this CFR 309, the transmitting station reads the preset original in the reading unit 110, encodes it in the encoding unit 106 via the overall control unit 112, and transmits image information 310 to the other party through the modem. do. If the receiving station can successfully receive the image information 310, M
After returning CF312, the transmitting station finally sends DCN313 and ends the communication. In addition, in the current explanation, after pressing the start button, CML relay 201 and switch 205 are
However, the switching may be made at the time the pickup circuit 204 receives the CED 301.

Next, the operation at the time of reception will be explained using FIGS. 1, 2, and 4. FIG. 4 shows the communication procedure when the other party uses an automatic transmission facsimile, which is basically based on CCITT Recommendation T. 30. In the figure, 401 is a calling tone (CNG) indicating that the calling station is a non-voice terminal.
It is. Here, a case will be described in which the transmitting station performs automatic transmission and the receiving station performs manual reception. When the receiving station receives a call, it picks up the telephone 102 and answers the call. When the other party is an automatic transmission facsimile, the CNG 401 is heard, so the receiving station receives this CNG 401 through the pickup circuit 204 and sets the CML relay 201 to a.
Switch to the side, CED301, NSF301, CSI3
03 and DIS304 signals. For these signals, the transmitting station transmits NSS305, TSI306, DC
Since S307 is sent, this signal is also received in the same way as CNG401 and analyzed by the procedure control unit 105. moreover,
The ID detection section 107 detects the ID signal of the transmitting station included in these signals, and displays the detected ID on the ID display section 108 via the overall control section 112. The transmitting station is also TC
If the transmitting station sends F308 but does not return a response signal (for example, CFR309) to the receiving station, the transmitting station repeatedly sends NSS305, TSI306, and DSS307 up to three times. The receiving station has an ID display section 10
Check the ID of the transmitting station displayed in 8, and if it is a station you can receive from, press the start button on the operation unit 109, and when the TCF308 is successfully received, the CFR309
send. Upon receiving this CFR 309, the transmitting station subsequently transmits image information 310. The receiving station uses this picture information 3
10 is decoded by the encoding unit 106 and then printed by the printing unit 111 via the overall control unit 112. Note that, as the ID signal of the transmitting station, the telephone number of the transmitting station included in the TSI 306 may be used, or the name of the transmitting station inserted in the ID area of the NSS 305 may be used. In the explanation using Fig. 4, the CNG40 from the other party
1 is automatically detected via the pickup circuit 204 and the CML relay 201 is switched to detect the other party's ID signal. However, the pickup circuit 204 may also be used to detect the other party's ID signal.

Further, in the present invention, an ID monitor button for detecting the ID of the other party is provided on the operation unit 109, and signals such as CED 301 and CNG 401 are transmitted to the telephone 10.
After listening in step 2, the ID signal may be detected and displayed by pressing this ID monitor button. Furthermore, the communication procedures in FIGS. 3 and 4 are based on CCITT recommendation T. 3
5 and 6, an example of a non-standard procedure to which the present invention is easily applied will be described.

In FIG. 5, 501 is T. A reception start signal (RSC: Receive Start Sign) that instructs the transmitting station to start reception is a signal that is not present in
al). The difference from FIG. 4 is that in the standard procedure of FIG.
CF308 was sent, but in the example of Figure 5, NSS3
05, TSI306, and DCS307, the transmitting station does not continue to transmit TCF308 for a predetermined period of time until the receiving station detects an ID signal, displays the other party's ID, and presses the reception start button. is NSS305, TS
Repeatedly transmit I306 and DCS307. Then, when the receiving station presses the start button, it sends back RSC501, and when the transmitting station receives this RSC501, it sends TCF3
08 is sent, and communication is thereafter performed in the same manner as the standard procedure.

Furthermore, in FIG. 6, reference numeral 601 denotes an IDS (Identification System) indicating an ID signal of a transmitting station.
Signal). In the example of FIG. 6, the transmitting station that performs automatic transmission transmits the IDS 601 indicating the ID of the transmitting station following the CND 401, and the transmitting station repeats the CND 401 for a predetermined time until the CED 301 etc. arrive from the receiving station. and sends IDS601. The receiving station displays the ID of the transmitting station by receiving this IDS 601. Then, once you have confirmed that the recipient is a person you can receive from, press the start button. After this, CED
301, NSF 302, CSI 303, and DIS 304, and thereafter communication is performed in the same manner as in the standard procedure.

Next, a specific example of the ID display section 108 will be explained.

FIG. 7(1) shows an LCD (Liq
In this example, 701 is an LCD controller,
702 is an LCD. In this case, for example, the detected ID may be a phone number "0".
3-3111-1234”, enter “03” as is.
-3111-1234” is displayed on the LCD 702. Also, if the detected ID is “Suzuki Taro”, “
"Suzuki Taro" is displayed.

FIG. 7(2) shows a case where audio is used instead of visual display, where 703 is a speech synthesis section, 704 is an output amplifier, and 705 is a speaker. In this case, for example, if the detected ID is "Suzuki Taro",
A message such as "Suzuki Tarokara Fax Death" is output from the speaker 705. This audio may be output to the telephone 102 instead of being output to the speaker 705.

[0020] In the above explanation, an example was shown in which the detected ID is displayed as is on the LCD or output as voice, but in this case, if the ID is a telephone number, it is difficult to know who the other party is. I don't know right away. Therefore, as shown in (C), a telephone number and its corresponding name are registered in advance in the overall control unit 112, and when an ID is detected, this is searched and the corresponding name is displayed on the LCD shown in FIG. or
It may also be configured to output audio. If the ID is not registered, communication may be disabled, or the detected ID itself may be displayed as described above.

Now, in the above explanation, the ID signal is NSF
Although the case where the ID signal is included in a procedure signal such as 302 or CSI 303 has been described, the audio signal itself may be used as the ID signal. In this case, for example, the automatic transmitting station
Before or after NG401, a voice message such as "This is Suzuki. Please receive the facsimile." is sent out, and the receiving station receives this and outputs it as voice, or recognizes the voice and displays it on the LCD. You may.
