Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine (hereinafter referred to as FAX), and more particularly to a FAX transceiver.

[0002]

2. Description of the Related Art Conventionally, in transmission by FAX or the like, the transmission is started by inputting a dial number of the other party at the start of transmission and pressing a transmission button. Further, it is also possible to register a dial number having a high frequency in advance and start transmission by pressing a registration button.

On the other hand, in the case of reception by a conventional FAX or the like, normally, all the received originals are automatically printed. However, there is also an apparatus in which the received original document is temporarily recorded in the memory and the recipient can later select and print the required original document.

[0004]

However, in the above-mentioned conventional FAX, even if the dialing number of the other party is erroneously input at the start of transmission, the transmission is started, so that a confidential document may be leaked elsewhere.

Regarding reception, an unexpected document may be sent from a third party who does not know at all, such as direct mail. In this case, even if the original document is once recorded in the memory, it is not known who the transmission destination is or the original document that requires the transmission document, so that the original document is printed and the recording paper is wasted wastefully. There was that.

[0006]

According to the present invention, there is provided a transmission flag output section for outputting either transmission flag valid / invalid, a reception flag output section for outputting either reception flag valid / invalid, and its own terminal. Has an ID and is the ID of the recipient from the recipient
Is added to the FAX, and an ID register for checking whether the ID of the receiver sent from the sender matches the ID of its own terminal is provided in the FAX.

[0007]

In the FAX having the above-described structure, when transmitting, the ID of the other side (reception side) is transmitted from the transmission side together with the ID transmission command, and if the transmitted ID and the ID of the reception side match, a message is displayed. Proceed to transmission and if there is no match the line is disconnected. When receiving, if the ID of the receiving side sent from the sending side together with the ID sending command and the ID of the receiving side match, the process proceeds to message reception, and if they do not match, the line is disconnected. .

[0008]

FIG. 1 is a block diagram showing an embodiment of the present invention. In this embodiment, the case of G3 FAX will be described. In FIG. 1, 1-1 is a central processing unit, 1-
Reference numeral 2 denotes a transmission flag output unit, which means that when a transmission flag “1” is output, the identification number (hereinafter referred to as “ID”) of the receiving party is transmitted so that the reception side performs ID verification. Is output, the ID is not transmitted and the receiving side I
It also means that D matching is also entrusted to the receiving side. Next 1-3
Is a reception flag output unit, and when outputting the reception flag '1', only the received document that matches the ID of itself is received,
When the reception flag “0” is output, it means that ID verification is not performed. Further, 1-4 is an ID register for storing an ID, 1-5 is a battery, 1-6 is an operation unit, and 1-7 is a display unit.

Each of the flags output from the transmission flag output section 1-2 and the reception flag output section 1-3 is composed of 1 bit, and may be composed of a DIP switch or a flip-flop. Good. Battery 1-5 if configured with flip-flops
It is backed up with, and the contents can be retained even in the event of power failure or power off. The ID register 1-4 is composed of a read only memory (ROM) or a DIP switch.

In the operation unit 1-6, the transmission flag output unit 1-2 and the reception flag output unit 1-3 can be set / reset. However, the contents of the ID register 1-4 are written at the time of being installed in advance. Since the ID number is used and managed in a certain closed user group, confidentiality can be maintained because it is unknown to a third party other than the user group. Further, the display unit 1-7 displays an alarm or the like when the ID of the receiving party is not verified.

In FIG. 2, the flags output from the transmission flag output section 1-2 and the reception flag output section 1-3 are both "0".
Or when it is in the state of "1", the ID register 1-4
FIG. 6 is a diagram showing a correspondence with the case where the ID collating function is “present” or “absent” in FIG.

Here, when the transmission flag and the reception flag are both "0" and the ID collation is "none", the conventional G3 FAX is used.
It has the same function as. Also, the transmission flag is "0", the reception flag is "1", and the ID verification is "Yes".
In this case, it is possible to confirm the destination at the time of reception, and it is possible to prevent waste of recording paper without printing useless transmission originals. Next, the transmission flag is "1",
When the reception flag is “0” and the ID collation is “present”, the recipient can be confirmed at the time of transmission, and erroneous delivery of the confidential document can be prevented. Furthermore, when both the transmission flag and the reception flag are “1” and the ID collation is “present”, the effect of and can be obtained at the same time.

Next, FIG. 3 is a diagram showing an example of the novel command of the present invention. In FIG. 3, the upper part shows the frame format of G3 FAX, F is a flag, A is an address, C is a control command, I is an information part, and FCS is a frame check sequence. Further, FCF indicates a facsimile control field, and FIF indicates a facsimile information field.
Two commands are newly added here. One is a command sent from the sending side to the receiving side, as shown in the middle row, and will be called an ID sending command. The other is a command sent from the receiving side to the transmitting side as shown in the lower stage, which will be referred to as an ID unmatch command.

Here, the ID transmission command is the ID of the receiving side.
, Which is a command for sending the command, and the FCF has 8 bits of the command type followed by 8 bits of the partner ID. The ID unmatch command is a command for returning to the sender that the ID received by the receiver does not match its own ID.
8-bit command type is entered in FCF. Note that in the ID unmatch command, the ID is not returned to the transmitting side because of confidentiality.

FIG. 4 is a diagram showing an example of a conventional G3 FAX signal sequence, which complies with CCITT Recommendation T30, and a detailed description thereof is omitted here. However, in the present invention, in the conventional FAX signal sequence shown in FIG. 4, in the phase B, the ID verification of the other party is performed using the new command described with reference to FIG. Next, the operation of the present invention will be described with reference to FIGS. Figure 5
Is a flowchart showing the operation of the transmitting side in phase B of the present invention, FIG. 6 is a flowchart showing the operation of the receiving side, and FIGS. 7 and 8 are diagrams showing an example of the signal sequence in phase B of the present invention.

In FIG. 5, the operation part on the transmission side according to the present invention is shown by broken lines, and in FIG. 7, an example of the signal sequence is shown. Here, FIG.
In (a), the transmission flag of the transmission side is "1" and the reception flag of the reception side is "1" or "0", and the ID sent by the ID transmission command is collated with the ID of the reception side. In case of ID transmission, training TC
If training is normal in F, CFR is returned to the sender,
After entering Phase C, FAX transmission / reception proceeds normally. Next, in FIG. 7B, the point different from FIG. 7A is that the collation of the IDs on the receiving side does not match. When an ID different from its own ID is sent by the sent ID send command, the receiver returns an ID unmatch command to the sender, then enters phase E, the line is disconnected, and FAX transmission / reception is aborted. To be

Further, in FIG. 6, the operation part on the receiving side according to the present invention is shown by broken lines as in FIG. 5, and in FIG. 8, an example of the signal sequence is shown. Here, in FIG. 8A, the transmission flag of the transmission side is “0” and the reception flag of the reception side is “1”, and the transmission side transmits the training TCF after DCS in phase B. Then, waiting for an ID transmission command, after a certain time elapses, the reception side returns an ID unmatch command to the transmission side due to timeout, enters phase E, the line is disconnected and the FAX transmission / reception is terminated. In FIG. 8B, the transmission flag on the transmission side and the reception flag on the reception side are both “0”, no ID collation check is performed, and the same signal sequence as in the conventional G3 FAX is taken.

All the above operation examples show the case where the calling party is transmitting and the called party is receiving, and "0" of the transmission flag and the reception flag means invalid, and "1" means valid. To do. Therefore, when both the transmission and reception flags are “1”, it means that ID verification can be performed for both transmission and reception.
On the other hand, when the transmission / reception flag is “0”, it means that the original G3 FAX can exchange documents because the same signal sequence as that of the conventional G3 FAX is taken.

Further, the validity / invalidity of the transmission flag and the reception flag can be changed each time in the operation unit, so that not only the FAX devices of the present invention but the conventional G3 can be used.
Documents can be exchanged with a fax machine by a simple switching operation.

Furthermore, in this embodiment, G3FA is used.
Although the case of X has been described, the present invention is not limited to G3 FAX, but may be applied to a digital transmission FAX such as G4 FAX or an analog FAX other than G3 FAX.

[0021]

As described above in detail, according to the present invention, a transmission / reception flag output unit for outputting a valid / invalid transmission / reception flag and an ID register are provided to a terminal, and a command for transmitting the ID of the other party from the transmission side is provided. In addition, since the receiving side collates the match / mismatch with its own ID, it is possible to prevent erroneous transmission due to a dialing error, etc., and prevent confidential documents from leaking to a third party.

Also, at the time of reception, by enabling the reception flag of the own terminal, the original is received only from the destination to which the ID of the own terminal has been sent, so that it is sent randomly from a third party. The line will not be unnecessarily occupied by incoming direct mail, and the waste of recording paper can be prevented.
