FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus to which the present invention is applied.

In FIG. 1, the main control unit 1 is mainly composed of a microcomputer, and via a bus 9, a reading unit 2, a recording unit 3, a calling station ID detection unit 4, a communication control unit 5, an input unit. 6, which is connected to the data storage unit 7 and the ID comparison unit 8 and controls the entire device.

The reading unit 2 reads a document to be transmitted, and is composed of an image sensor and the like.

The recording unit 3 outputs the received image data as a hard copy. Calling station ID detector 4
Detects the ID (identification information) of the calling station from the transmission terminal identification signal TSI or the calling terminal identification signal CIG included in the standardized transmission control procedure for facsimile communication. Here, the calling station ID (calling station ID) is, for example, the telephone number of the calling station.

The input unit 6 is for inputting various data used in this device. For the purpose of the present invention, the ID of the other device which is the calling station wishing the closed communication, such as a telephone number or It is used to enter the abbreviated number.

The data storage unit 7 stores various data used by this device, and is an ID (registered ID) of the partner station that desires the closed communication input by the input unit 6, for example, a telephone of the partner station. The number or its abbreviated number is registered.

Further, the ID comparison unit 8 compares the calling station ID detected by the calling station ID detection unit 4 with the ID (registered ID) registered in advance in the data storage unit 7, and the two match. Check whether to do.

Then, the communication control unit 5 determines whether or not the closed communication is performed based on the comparison result of the ID comparison unit 8.

Here, FIG. 2 shows M registration IDs stored in the data storage unit 7. In FIG. 2, although not actually attached, the numbers of ID1 to IDM are made to correspond to the respective registration IDs, for the purpose of the description below.

Next, the procedure of the discrimination process, which is executed by the communication control section 5 and determines whether or not the closed communication is performed, will be described with reference to the flowchart of FIG. In this embodiment, the identification information (calling station ID) of the calling station is detected from the transmission terminal identification signal TSI or the calling terminal identification signal CIG included in the standardized transmission control procedure for facsimile communication. Here, the transmission terminal identification signal TSI typically includes identification information indicating the transmission terminal, in this case, the calling station ID, and the calling terminal identification signal CIG includes identification information indicating the calling terminal, that is, The calling station ID is included as standard.

The calling tone CNG generated on the calling station side by the dial operation of the calling station is received by the called station, and the called terminal identification signal CED and the digital identification signal DIS are sent from the called station side to the calling station side. First, the called station checks whether or not the transmission terminal identification signal TSI is detected in the signals transmitted from the calling station side (step 1).
00).

When the transmission terminal identification signal TSI is detected (step 101), the transmission terminal identification signal TSI is detected.
The transmitting terminal identification information (transmitting terminal ID) included in the message, that is, the calling station ID is extracted (step 102), and step 1
Go to 05.

If the transmitting terminal identification signal TSI is not detected in step 101, the calling terminal identification signal CIG is next detected.
Is detected (step 10).
3). Here, when the calling terminal identification signal CIG is detected, the calling terminal identification information (calling terminal ID) included in the calling terminal identification signal CIG, that is, the calling station ID is extracted (step 104), Go to step 105.

When the calling terminal identification signal CIG is not detected in step 103, the line is disconnected (step 108) and this process is terminated.

In step 105, an ID registered in advance in the data storage unit 7 shown in FIG. 1, that is, a registered ID.
(Step 105), and the calling station ID extracted in step 102 or the calling station I extracted in step 103 is searched.
Check if there is a match with D (step 10)
6).

If there is a match, it is considered that the closed communication can be performed with the calling station, and then the normal communication procedure is followed to shift to the closed communication with the calling side (step 10).
7) This process ends.

On the other hand, if it is determined in step 107 that there is no match, the line is disconnected (step 108) and this process ends.

In this embodiment, in step 105, the data extracted in step 102 or in step 10
The calling station ID extracted in step 4 was compared with all digits of the registered ID registered in advance in the data storage unit 7 to check for a match, but only the value of a predetermined number of digits from the end of the ID was compared. The closed communication may be permitted if they match here. With this configuration, the processing efficiency can be improved by appropriately adjusting the number of collating digits, and the selection range can be adjusted to the calling station that is the target of the closed area communication.

FIG. 4 shows an example of processing in the case of such a configuration. FIG. 4 shows a structure corresponding to step 106 in the structure shown in FIG. That is, in this configuration, step 106 in FIG. 3 is replaced by the configuration shown in FIG.

FIG. 3 shows a case where the number of reference digits is set to N digits. The number of reference digits can be changed by appropriately changing the value N.

Further, here, a case is shown in which the number of registered IDs to be registered is set to M of ID1 to IDM shown in FIG. 2, and the number of registered IDs is appropriately changed by changing the value M. be able to.

Here, first, m = 1 is set (step 200), n = 1 is set (step 201), and the calling station ID extracted in step 102 or step 103 in step 105, That is, receive I
The nth value dn from the end of D, here the last value is extracted (step 202), and then the nth value Dn from the end of the registration ID of the number IDn registered in the data storage unit 7 in advance. , Here the last value is extracted (step 2
03), it is checked whether or not some of the registration IDs satisfy dn = Dn (step 204). Where dn =
If there is a condition that Dn holds, a process n that adds 1 to n
← n + 1 is executed (step 205), it is checked whether n> N (step 205), the process returns to step 202, and in the same manner, the value of each digit of the ID is sequentially compared from the end side, and n is the same for the same ID. When the preset N is reached, that is, when n> N is satisfied, the process proceeds to step 107 in FIG. However, if dn = Dn is not satisfied in step 204, a process m ← m + 1 for adding 1 to m is executed (step 207) to check whether m> M (step 20).
8) Return to step 201, and then step 201, 2
02, 203, 204, 207 and 208 are repeated. Then, even if all the registration IDs are compared, if the calling station ID and the registration ID do not match, that is, if m> M holds,
It is determined that the closed communication is not permitted, and the process proceeds to step 108 in FIG.

FIGS. 5 and 6 show an example of the control procedure when the processing of FIG. 3 or 4 is performed, and FIG. 5 shows the case where the calling station is the original transmission station. , FIG.
The case where the called station is the original transmission station is shown.

That is, in FIG. 5, when a calling side CNG is transmitted from the calling side A to the called side B, and in response to this, a called terminal identification signal CED is returned from the called side B, the calling side is called. A non-standard function setting signal NSS which is an optional signal, a transmission terminal identification signal TSI which is a standard signal, and a digital command signal DCS are transmitted from the calling side A to the called side B, and a training check signal TCF is further transmitted. At the called side B, the transmitting terminal identification signal T
The SI is monitored (TSI check), and the calling station ID is detected from the transmission terminal identification signal TSI.

Here, if the calling station ID detected from the transmission terminal identification signal TSI matches the registration ID registered in advance in the data storage unit 7 shown in FIG. 1, closed communication is permitted, and reception preparation is performed. The confirmation signal CFR or the training failure signal FTT signal is transmitted from the called party B to the calling party A, and thereafter, a predetermined processing procedure is executed to shift to closed communication in which the calling party A sends a document to the called party B. To do.

On the other hand, if the calling station ID detected from the transmission terminal identification signal TSI does not match the registration ID registered in advance in the data storage unit 7 shown in FIG. 1, this closed area communication is not permitted, The line is open.

Further, in FIG. 6, a calling tone CNG is transmitted from the calling side A to the called side B, and in response to this, a called terminal identification signal CED is returned from the called side B,
Furthermore, a non-standard function identification signal NSF, which is an optional signal,
When the called terminal identification signal CSI and the digital identification signal, which is a standard signal, are returned, the calling side A to the called side B,
A non-standard function command signal NSC which is an option signal, a calling terminal identification signal CIG and a digital transmission command signal DTC which are standard signals are transmitted. The called side B monitors the calling terminal identification signal CIG among these signals (CIG check), and detects the calling station ID from this calling terminal identification signal CIG.

Here, if the calling station ID detected from the calling terminal identification signal CIG matches the registration ID registered in advance in the data storage unit 7 shown in FIG. Non-standard function setting signal NSS, which is an optional signal, from the calling side B to the calling side A, and a transmitting terminal identification signal TS
I and a digital command signal DCS which is a standard signal are transmitted, and a training check signal TCF is further transmitted, and thereafter, a predetermined processing procedure is executed to shift to closed area communication in which a document is transmitted from the called side B to the calling side A. To do.

On the other hand, if the calling station ID detected from the calling terminal identification signal CIG does not match the registration ID registered in advance in the data storage unit 7 shown in FIG. 1, this closed area communication is not permitted. , The line is open.

As described above, in this embodiment, the called station side detects the calling station identification information, while the called station side determines the other party,
That is, since the identification information of the calling station that permits the closed communication is registered and the closed communication can be performed only when the two match, it is possible to give the called party a right to decide whether or not to perform the communication. It becomes possible for the own station to communicate only with the calling station that desires to communicate, it is possible to prevent an unnecessary incoming call from a third party, and prevent unnecessary data from being printed.

Further, unlike the conventional case, since the option command signal is not used, it is possible to perform the closed communication with the models of other companies having different option commands.

Further, in this embodiment, since the called side can perform the closed communication even in the automatic reception mode, the closed communication can be performed even when the caller is not in the absence.
