BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile communication device for providing a facsimile transmission / reception service to users of facilities such as hotels temporarily used by many persons.

[0002]

2. Description of the Related Art Conventionally, private branch exchanges (PB
When a facsimile machine is connected to the extension of (X), there is no problem in making a call to the public line network (external line).
Unless a dial-in number (contract) is set for each extension port as shown in Japanese Patent No. 7926, an incoming call from the public line network is not directly connected to each extension port. That is,
There is a problem that a facsimile document cannot be automatically sent to a PBX extension facsimile machine. Setting a dial-in contract for an extension of each guest room of a hotel or the like is extremely costly for the hotel.

As a facsimile communication device that solves this problem, a hotel facsimile system developed based on the "communication network" described in Japanese Patent Publication No. 501501/1993 has already been implemented.

An example of such a hotel facsimile system will be described with reference to FIGS. 11 and 12.

In FIG. 11, a private branch exchange 2 installed in a hotel 1 which is one of facilities used by many users is connected to a public network 3 of NTT. Each of the guest rooms R1 to Rm in the hotel 1 has an extension facsimile machine F1 to an extension facsimile machine F1 including a facsimile machine 4 and an adapter 5 interposed between the facsimile machine 4 and the private branch exchange 2. Fm is arranged. Each adapter device 5 has a pocket bell receiver (also called a pager for calling only) 5a built therein and is connected to an extension of the private branch exchange device 2. Further, the private branch exchange device 2 is connected to a facsimile management device 6 for monitoring the usage status of the extension facsimile device in each guest room and managing billing data for each guest room. By the way, in general, the pager receiver 5a is designed to emit an LED or ring a buzzer when called, and in this system, the light emission signal of the LED of the pager receiver 5a is transmitted by a phototransistor or the like. The adapter device 5 is activated by receiving the light and converting it into an electric signal.

The center device 7 is connected to the public line network 3 by a plurality of physical lines, and a large number of dial-in contracts exceeding the number of physical lines are set, and the dial-in number held is assigned as a facsimile number. When
While the mailboxes M1 to Mn, which are facsimile information storage units corresponding to each of them, are created, a correspondence table 7a such as pager numbers and adapter codes described later is stored.

The pager originating station 8 generates a calling signal including a pager number notified from the center device 7 and sends it out by radio.

The adapter device 5 in each guest room is preset with an adapter ID code, a guest room number, a hotel number, etc., which is identification information for the center device 7 to identify them. A pager number for the center device 7 to selectively call them via the pager transmitting station 8 is assigned in advance to the pocket bell receiver 5a built in.

On the other hand, as shown in FIG. 12, the center device 7 stores in advance a correspondence table 7a of adapter codes and pager numbers corresponding to the extension facsimile devices of each guest room.

To the guest who is a temporary user of the hotel 1, a specific guest room is assigned by the hotel 1, and a specific extension facsimile device is assigned. The guest assigned with the particular extension facsimile machine, prior to starting the use of the extension facsimile machine, obtains the facsimile number for the external communication partner to identify the extension facsimile machine. 4 by operating the adapter device 5
The center device 7 is called through to request a facsimile number allocation. After the call, the adapter device 5 notifies the center device 7 by sending identification information including its own adapter code on a predetermined protocol by a PB signal (DTMF signal) and sending it.

The center device 7 compares the transmitted adapter code with the correspondence table 7a, and assigns an unassigned facsimile number to the adapter code in the correspondence table 7a that is the same as the transmitted adapter code. Mailboxes M1 to Mn are created correspondingly. As described above, the mailboxes M1 to Mn each correspond to a specific facsimile number, and thus the transmitted adapter code is associated with the specific facsimile number. Further, since the adapter code and the pager number correspond to the mailbox and the corresponding facsimile number, it also corresponds to the corresponding pager number.

The above-mentioned facsimile number requesting operation before the guest starts using the extension facsimile machine will be referred to as a check-in operation hereinafter. In addition, after the check-in operation, contrary to the check-in operation,
A checkout operation, which is an operation for canceling the association between the adapter code and the facsimile number, can be performed by the guest or hotel.

The check-in operation is individually performed for each guest. After the check-in operation, the center device 7 transmits, to the extension facsimile device, an instruction manual in which a facsimile number associated with an adapter code that identifies the extension facsimile device is written. The guest informs the intended communication partner of the facsimile number described in the instruction manual received by the extension facsimile device, using the extension facsimile device, or by a telephone (not shown) or the like. .

Hotel 1 by the above check-in operation
12 shows an example of the correspondence between the extension facsimile machine assigned to the guest in each guest room, the mailbox of the center apparatus 7 and the corresponding facsimile number.
This will be described with reference to FIG.

In FIG. 1, a table Tg shows the assignment of guests to each guest room yesterday and today. As described above, the correspondence table 7a shows the correspondence between the adapter code and the pager number. The table Tm shows a mailbox provided in the center device 7 and a facsimile number corresponding to the mailbox.

Each guest room of the table Tg and the corresponding table 7
The adapter code and the pager number of a correspond to each other as described above. In the table Tg, the guest D stays in the guest room 1 and the guest E stays in the guest room 3 yesterday, and there are no guests in the other guest rooms. On the other hand, the guest A in the guest room 2 and the guest in the guest room 3 today. Assume that guest B stays in guest room m and guest does not stay in other guest rooms. These guests are indirectly associated with the correspondence table 7a by being assigned to each guest room.

Each guest carries out the check-in operation, and the center device 7 uses the adapter code
A facsimile number that is not yet associated with another extension facsimile device is assigned and a corresponding mailbox is created.

In the assignment of the adapter code to the mailbox, the code 1 is associated with the mailbox M2 as indicated by the link Ld and the code 3 is assigned as indicated by the link Le in "Yesterday". It is associated with the mailbox M1.

On the other hand, in "Today", the link Ld and the link Le associated with yesterday are released by the check-out operation, while the code 2 is associated with the mailbox M1 as indicated by the link La. , The code 3 is associated with the mailbox M2 as indicated by the link Lb, and the code m is associated with the mailbox M3 as indicated by the link Lc.

As described above, in "Today", for example, among the guests A, B, and C to which the mailbox (facsimile number) is assigned via the adapter code, for example, the facsimile information is provided to the guest A. The external communication partner (facsimile device 9 shown in FIG. 11) who wants to send a call to the facsimile number contacted by the guest A, that is, “FAX number 1”, sends the facsimile information. .

The center device 7 receives the facsimile information transmitted from the facsimile device 9 and temporarily stores it in the mailbox M1 corresponding to "FAX number 1." Then, the "page number 2" corresponding to the "adapter code 2" to which the "mail box M1" is assigned is notified to the pager originating station 8, and the pager originating station 8 calls the pager number including the notified pager number. A signal is generated and wirelessly transmitted.

The extension facsimile apparatus corresponding to the transmitted "Bell number 2", that is, the pocket bell receiver 5a built in the adapter apparatus 5 constituting the extension facsimile apparatus F2 responds and the LED emits light. Is received by the phototransistor and converted into an electric signal to activate the adapter device 5. Activated adapter device 5
Sends a call to the center device 7 via the private branch exchange device 2 and notifies the identification information including its own adapter code on a PB (push button) signal, and also notifies the facsimile device 4 connected to the own device. Call and connect the line to the center device 7. The center device 7 transmits the facsimile information stored in the mailbox corresponding to the notified adapter code, that is, the mailbox M1, to the extension facsimile device F2 that has called, and the extension facsimile device F2 receives the facsimile information. Is received and is recorded and output. Thus, the facsimile information transmitted by the facsimile machine 9 reaches the guest A.

For the transmission from the extension facsimile machine of the hotel to the external facsimile machine, the facsimile machine 4 in the hotel directly dials the facsimile number of the transmission destination to automatically send the facsimile machine to the head of the facsimile number by the adapter machine 5. Then, "0" is added to the outgoing line and the external line is transmitted, and the same process as the normal facsimile transmission can be performed.

The toll-free number of the center device 7 is set in the adapter device 5, and the extension facsimile device makes a call to the center device 7 using the toll-free number. Therefore, the line usage fee for receiving the facsimile information from the outside is not burdened by the hotel and its guests, but is paid by the administrator of the center apparatus 7, and the administrator of the center apparatus 7 uses the facsimile. Service charges for sending and receiving information will be collected from hotels and guests.

As described above, according to the above-mentioned facsimile communication device, the hotel side does not have to provide dial-in lines with the public line network 3 by the number of guest rooms, and the number of external lines is much smaller than that. Facsimile information can be directly transmitted from the facsimile device to the extension facsimile device in each passenger room. For this reason, the hotel side can significantly reduce the line contract fee, and can save the trouble of handing over the facsimile reception document received from the outside of the hotel to the guest, and by mistake, another It is possible to avoid handing over to the guest, and it is possible to provide a highly convenient facsimile communication service to the guest.

[0026]

However, in such a conventional facsimile communication apparatus, the dial-in number used as the mailbox identification number of the center apparatus is used as a temporary user such as a hotel guest. In order to prevent a wrong call, the number once assigned cannot be reassigned immediately. Therefore, many dial-in numbers must be prepared.

That is, when a mailbox to be used temporarily is created corresponding to a dial-in number or the like, immediately after the use of a certain mailbox (after the check-out operation), the same number is used for another person. When a mailbox is created, the user of the previous mailbox, who does not know it, sends the facsimile information to another person who is newly assigned. This causes problems such as leaking confidential information to others, so you should avoid using the same number for a while.
However, if this is done, a large number of numbers corresponding to several times the number of rooms in a hotel or the like is required, and when using numbers such as dial-in, a large cost burden is imposed.

The present invention has been made in order to solve such a problem, and provides a facsimile communication apparatus capable of preventing information leakage due to an erroneous incoming call and an increase in cost burden due to an increase in the number of dial-in contracts. The purpose is to do.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
An embodiment of each invention of the present application will be described in detail. Here, a case where these inventions are applied to the hotel facsimile system shown in FIG. 11 will be described. Since the overall configuration is similar to that shown in FIGS. 11 and 12,
Further illustration and description thereof will be omitted, and description will be made with reference to them as necessary.

FIG. 1 is a block diagram showing a main configuration of a center device which is a constituent element for realizing each invention.

The center device 7, which serves as a FAX server,
It is realized by a general-purpose computer including a console 71 including a display and a keyboard and a main body 72. The main body 72 contains a CPU (central processing unit) 73, a memory 74, a voice codec 75, a FAX board 76, a hard disk device (HD) 77, etc., and these are connected to each other via a bus 78.

The CPU 73 controls the entire apparatus and realizes the characteristic functions of each invention described later. The memory 74 is composed of a read-only ROM and a readable / writable RAM, and serves as a storage area for programs and data executed by the CPU 73 and a work area when the programs are executed. The voice codec 75 performs A / D conversion and D / A conversion of a voice signal used for a voice message or the like. F
The AX boards 76 are boards for adding a facsimile communication function to a general-purpose computer, and a plurality of boards are provided and each is connected to the public telephone line PSTN. The hard disk (HD) 77 is used for storing the programs loaded in the memory 74 and for creating the above-mentioned mailbox, and has a large capacity so that a large number of facsimile image information can be stored. To be

The hard disk 77 stores a list of in-service telephone numbers and a list of in-service telephone numbers as shown in FIGS. 2A and 2B, and various lists described later, which are referred to by the CPU 73. The in-service telephone number list is a list in which the assigned facsimile numbers (dial-in numbers) are registered. On the other hand, the non-service telephone number list is a list in which unassigned facsimile numbers (dial-in numbers) are registered. When a new facsimile number is newly assigned, the non-service telephone number list is added to the top of the non-service telephone number list. A number is assigned and moved to the in-service number list. Further, the numbers whose allocation has been canceled by the above-mentioned check-out operation are moved from the in-service telephone number list to the end of the non-in-service telephone number list.

Next, an embodiment of the invention described in claim 1 will be described. The present invention is realized by the CPU 73 of the center device 7 executing the processing program shown in the flowchart of FIG.

The center device 7 is a public telephone line PSTN.
It waits for a dial-in (DI) incoming call via (No loop of decision 101). If there is a dial-in (DI) incoming call (Yes in judgment 101), this dial-in (D)
I) The number is checked, and it is determined whether or not this number is in service from the in-service number list shown in FIG. 2A (process 102 → determination 103). If the service is in progress, the process proceeds to normal FAX reception (Yes in determination 103 → process 109). The received facsimile information is stored in the corresponding mailbox, and is transmitted to the corresponding facsimile device 4 in the hotel 1 shown in FIG. 11 through the procedure as described in the description of the prior art.

On the other hand, if the received dial-in number is not in service (No in decision 103), the facsimile reception protocol is continued for a while, and the TSI (Transmitting Station Identification) sent from the sender is sent to the receiver. The identification number of its own device to be notified) is received, and the FAX number is extracted from the received TSI and temporarily stored (process 104 → process 105).

After this, a voice message such as "This number is not serviced" is transmitted to the sender, and this communication is temporarily disconnected (process 106 → process 107). Then, the FAX number obtained from the TSI is used to make a call to the sender, and a facsimile message having the same contents as the voice message described above is transmitted as a warning FAX (process 108). A voice message stating that the FAX number to be transmitted is not in service is transmitted from the facsimile machine of the transmission source, and a facsimile message having the same content is recorded and output on the recording paper immediately after the communication is cut off. Here, in the case of a facsimile device, a facsimile message is transmitted in addition to a voice message. In general, the transmission is performed by simply setting the transmission original on the device, setting the destination, and pressing the start button. Since the transmission is performed, the operator often leaves the place when the start button is pressed, and there is a high possibility that the operator does not hear the voice message.

In this way, the hotel guest can use the non-service facsimile number, which has been checked out and deallocated, to the originator who has called without knowing it. You can be sure that you are not told. Therefore, it is possible to effectively prevent an erroneous incoming call when this facsimile number is newly assigned to another person, and to prevent leakage of confidential information or the like. Further, it is not necessary to additionally hold the number of dial-in lines of the center device 7 in case of the above-mentioned mistaken incoming call, and it is possible to reduce the cost for opening and maintaining the center device.

In the above embodiment, the TSI of the caller who received the dial-in number during non-service is used only for transmitting the warning FAX.
If I is registered as an incorrect call reception list as shown in FIG. 2C and the dial-in number is assigned and the service is in progress, referring to the incorrect reception call list, if The communication may be disconnected without shifting to FAX reception.

Next, an embodiment of the invention described in claim 2 will be described. The present invention is realized by the CPU 73 of the center device 7 executing the processing program shown in the flowchart of FIG.

Similar to the above embodiment, the center device 7 waits for a dial-in (DI) incoming call through the public telephone line PSTN (No loop of decision 201). When a dial-in (DI) call is received (Yes in judgment 201), this dial-in (DI) number is checked, and it is judged from the in-service number list shown in FIG. 5A whether this number is in service or not. Yes (process 202 → decision 203).

If the received dial-in number is not in service (No in judgment 203), the facsimile reception protocol is continued for a while, the TSI sent from the sender is received, and the received TSI is received. F
The AX number is extracted and temporarily stored (process 204 → process 205).

After this, a voice message such as "This number is not serviced" is transmitted to the originator, and this communication is temporarily disconnected (process 206 → process 20).
7). Then, the FAX number acquired from the TSI is used to make a call to the sender, and a facsimile message having the same content as the voice message described above is transmitted as a warning FAX (process 208). A voice message stating that the FAX number to be transmitted is not in service is transmitted from the facsimile apparatus of the transmission source, and a facsimile message having the same content is recorded and output on the recording paper immediately after the communication is cut off.

On the other hand, if the service is in progress, the TSI is received and recorded in association with the dial-in number (Yes in judgment 203 → process 209). The recorded TSI is
When the dial-in number is unassigned and becomes non-service, as shown in FIG. 5 (B), “call received during service until last time” is associated with each number in the non-service telephone number list. Registered in the "TSI list"
It is referred to when each number is in service again.

When the TSI is received and recorded in the process 209, all the TSIs when this dial-in number is used in the past are called from the above-mentioned "TSI list received during the previous service" ( Process 210). Then, it is determined whether or not the one that matches the TSI of this time exists in the past TSI, and if it does not exist, it is not an erroneous incoming call and the process proceeds to FAX reception (N in judgment 211).
o → process 212). The received facsimile information is stored in the corresponding mailbox, and is transmitted to the corresponding facsimile device 4 in the hotel 1 through the procedure as described in the description of the related art.

On the other hand, if there is a match with the current TSI in the past TSI, it means that the incoming call is wrong.
Communication is disconnected without shifting to AX reception (decision 21)
1 = Yes → process 213).

By doing so, when the guest of the hotel checks out and the assigned facsimile number is newly assigned to another person, it is sent to the previous user without noticing it. It is possible to forcibly disconnect the wrong incoming call before the facsimile information is received. Therefore, it is possible to prevent leakage of confidential information, and it is not necessary to additionally hold the number of dial-in lines of the center device in case of a mistaken incoming call, thereby reducing the cost for opening and maintaining the center device. You can Further, in the present embodiment, as in the above-described embodiment, when the dial-in number of the incoming call is not in service, the facsimile message is transmitted in addition to the voice message to that effect. Message) can be omitted.
However, as in the present embodiment, the double countermeasure for preventing the false call reception can realize a system with higher reliability at a lower cost.

Next, an embodiment of the invention described in claim 3 will be described. The present invention is realized by the CPU 73 of the center apparatus 7 executing the processing program shown in the flowchart of FIG. 6, and the function of transmitting a warning FAX transmission for an error incoming call during service is added to the embodiment of claim 2. is there.

That is, as in the above-described embodiment, the center device 7 waits for a dial-in (DI) incoming call via the public telephone line PSTN (No loop of decision 301). When there is a dial-in (DI) incoming call (decision 301
Yes), the dial-in (DI) number is checked, and it is judged from the in-service telephone number list shown in FIG. 5A whether this number is in service (process 302 →
Decision 303).

If the received dial-in number is not in service (No in decision 303), the facsimile reception protocol is continued for a while and the TSI sent from the sender is received, and the received TSI is received. F
The AX number is extracted and temporarily stored (process 304 → process 305).

After this, a voice message such as "This number is not serviced" is transmitted to the sender, and this communication is temporarily disconnected (process 306 → process 30).
7). Then, the FAX number obtained from the TSI is used to make a call to the sender, and a facsimile message having the same content as the above-mentioned voice message is transmitted as a warning FAX (process 308). A voice message stating that the FAX number to be transmitted is not in service is transmitted from the facsimile machine of the transmission source, and a facsimile message of the same content is recorded and output on the recording paper immediately after the communication is cut off.

On the other hand, if the service is in progress, the TSI is received and recorded in association with the dial-in number (decision 3).
03 Yes → Process 309). The recorded TSI is associated with each number in the non-service telephone number list, as shown in FIG. 5B, when the dial-in number is deallocated and the service is out of service. Registered in the "TSI list received during the previous service",
It is referred to when each number is in service again.

When the TSI is received and recorded in the process 309, all the TSIs when this dial-in number is used in the past are called from the above-mentioned "TSI list of incoming calls during the previous service" ( Process 310). Then, it is determined whether or not the one that matches the TSI of this time exists in the past TSI, and if it does not exist, it is not an erroneous incoming call and the process proceeds to FAX reception (N in judgment 311).
o → process 312). The received facsimile information is stored in the corresponding mailbox, and is transmitted to the corresponding facsimile device 4 in the hotel 1 through the procedure as described in the description of the related art.

On the other hand, if there is a TSI that matches the current TSI in the past TSI, it means that a wrong call has been received.
Communication is cut off without shifting to FAX reception after extracting the FAX number of the transmission source from SI (Yes in judgment 311).
s → process 313 → process 314). Then, the FAX number acquired from the TSI is used to make a call to the sender, and a facsimile message indicating that the previous call is a wrong call is transmitted as a warning FAX (process 315). From the source facsimile machine, a facsimile message indicating that there is an incoming call immediately after the communication is cut off and the previous outgoing call is an erroneous incoming call is recorded and output on the recording paper.

By doing so, while having the same operation and effect as the above-mentioned embodiment, it is possible to surely inform the sender of the false incoming call that it is the false incoming call.
It is possible to prevent repeated false calls.

Next, an embodiment of the invention described in claim 4 will be described. The present invention is realized by the CPU 73 of the center device 7 executing the processing program shown in the flowcharts of FIGS. 7 and 8.

In this embodiment, when the hotel guest starts using the facsimile apparatus, that is, at the time of check-in operation, the user ID (for example, home telephone number) input by the guest is used as the dial-in number to be assigned. Correspondingly registered.

That is, when the guest inputs a special number for check-in, the facsimile device 4 shown in FIG. 11 calls the center device 7 through the adapter device 5 to request the facsimile number allocation. After the call, the adapter device 5 notifies the center device 7 by sending identification information such as its own adapter code and input user ID on the PB signal.

In FIG. 7, the center device 7 allocates an unassigned facsimile number corresponding to the transmitted adapter code and creates a mailbox corresponding to the assigned facsimile number, so that the adapter code becomes empty. It is assigned to the mailbox (process 401). As a result, the specific mailbox and the corresponding facsimile number are assigned to the extension facsimile apparatus including the adapter apparatus 5 that has requested the facsimile number assignment. In addition, the user ID transmitted together with the adapter code is registered in association with the assigned facsimile number (process 40).
2).

The center device 7 transmits the instruction manual including the facsimile number corresponding to the mailbox to the extension facsimile device to which the mailbox is assigned (process 403). The instruction manual is for the facsimile machine 4 with the line still connected to the center machine 7.
The facsimile apparatus 4 records and outputs the received instruction manual.

The guest uses the facsimile device 4 or a telephone (not shown) to inform the intended communication partner of the facsimile number recorded in the instruction manual recorded and output by the facsimile device 4. .

Now, in FIG. 8, similar to the above embodiment,
The center device 7 waits for an incoming dial-in (DI) call via the public telephone line PSTN (N in decision 501).
o loop). If there is a dial-in (DI) call (determination 501, Yes), this dial-in (DI) number is checked, and it is determined from the in-service number list shown in FIG. 9A whether this number is in service. Yes (Process 502)
→ Judgment 503).

If the received dial-in number is not in service (No in decision 503), the facsimile reception protocol is continued for a while and the TSI sent from the sender is received, and the received TSI is received. F
The AX number is extracted and temporarily stored (process 504 → process 505).

After this, a voice message such as "This number is not serviced" is transmitted to the sender, and this communication is temporarily disconnected (process 506 → process 50).
7). Then, the FAX number obtained from the TSI is used to make a call to the sender, and a facsimile message having the same content as the voice message described above is transmitted as a warning FAX (process 508). A voice message stating that the FAX number to be transmitted is not in service is transmitted from the facsimile machine of the transmission source, and a facsimile message having the same content is recorded and output on the recording paper immediately after the communication is cut off.

On the other hand, if the service is in progress, the TSI is received and recorded in association with the dial-in number and the user ID (Yes in judgment 503 → process 509). When the dial-in number is deallocated and the service is out of service, the recorded TSI is associated with each of the numbers in the service inactive phone number list as shown in FIG. 9B. Is registered in the TSI list received during the service up to, and as shown in FIG.
It is registered in the “TSI list of incoming calls during the previous service” associated with each user ID in the user ID list, and is referred to when each number comes into service again.

Now, when the TSI has been received and recorded in the above processing 509, when this dial-in number is used in the past from the "TSI list received during the previous service" shown in FIG. 9B. Call all TSI of
10). Then, in the past, it is determined whether or not there is the same TSI that has arrived at the dial-in number. If not, it is not an erroneous reception, and the process proceeds to FAX reception (No in determination 511 → process 512). The received facsimile information is stored in the corresponding mailbox, and is transmitted to the corresponding facsimile device 4 in the hotel 1 through the procedure as described in the description of the related art.

On the other hand, if the same TSI is received in the past, whether or not the same user ID has been registered in the past is checked in the user ID list shown in FIG. 9C (determination 511: Yes → judgment 513). If the same user ID has been registered in the past, whether or not there is the same TSI linked to the user ID is determined by the user I.
Check with the "TSI list that arrived during the previous service" associated with D (Yes in judgment 513 →
Decision 514). If they are the same, it means that the incoming call is not a wrong call, and the process proceeds to FAX reception (Yes in judgment 514 → process 512).

However, if the same user ID has not been registered in the past, or if the same TSI linked to the user ID is not registered even if the user IDs have been registered in the past, it is an erroneous incoming call and therefore FAX reception is not possible. The communication is disconnected without shifting (No in judgment 513 → process 515, or judgment 5)
13: Yes → No at decision 514 → Process 515).

By doing so, when the guest of the hotel checks out and the facsimile number that has been deallocated is newly assigned to another person, it is sent to the previous user without knowing it. It is possible to forcibly disconnect the wrong incoming call before the facsimile information is received. Therefore, it is possible to prevent leakage of confidential information, and it is not necessary to additionally hold the number of dial-in lines of the center device in case of a mistaken incoming call, thereby reducing the cost for opening and maintaining the center device. You can Also, in the unlikely event that the same user is assigned the same facsimile number, the user ID and user ID
It is possible to prevent the communication from being disconnected because it is determined that a wrong call is received from the TSI list up to the last time associated with the. Also in the present embodiment, as in the above embodiment, if the dial-in number of the incoming call is not in service, a facsimile message is transmitted in addition to the voice message to that effect. Message) can be omitted. However, as in the present embodiment, the double countermeasure for preventing the false call reception can realize a system with higher reliability at a lower cost.

Next, an embodiment of the invention described in claim 5 will be described. According to the present invention, the processing program shown in the flowcharts of FIGS.
The present invention is realized by executing the above method, and a function of transmitting a warning FAX for an erroneous incoming call during service is added to the embodiment of claim 4.

That is, also in the present embodiment, as in the previous embodiment, at the time of the check-in operation of the hotel guest,
The user ID entered by the guest is registered in correspondence with the dial-in number to be assigned.

Similar to the above-mentioned embodiment, the facsimile apparatus 4 calls the center apparatus 7 through the adapter apparatus 5 by the special guest's input operation for check-in to request the facsimile number allocation. After calling,
The adapter device 5 notifies the center device 7 by sending identification information such as its own adapter code and the entered user ID on the PB signal and sending it.

The center device 7, as shown in FIG.
By assigning an unassigned facsimile number to the transmitted adapter code and creating a mailbox corresponding to the assigned fax number,
The adapter code is assigned to the empty mailbox (process 401). As a result, the specific mailbox and the corresponding facsimile number are assigned to the extension facsimile apparatus including the adapter apparatus 5 that has requested the facsimile number assignment. In addition, the user ID transmitted together with the adapter code is registered in association with the assigned facsimile number (process 402).

The center device 7 transmits the instruction manual including the facsimile number corresponding to the mailbox to the extension facsimile device to which the mailbox is assigned (process 403). The instruction manual is for the facsimile machine 4 with the line still connected to the center machine 7.
The facsimile apparatus 4 records and outputs the received instruction manual.

The guest uses the facsimile device 4 or a telephone (not shown) to notify the intended communication partner of the facsimile number recorded in the instruction manual recorded and output by the facsimile device 4. .

In FIG. 10, the center device 7 waits for a dial-in (DI) call through the public telephone line PSTN as in the above embodiment (decision 601).
No loop). When a dial-in (DI) call is received (Yes in judgment 601), this dial-in (DI) number is checked to determine whether or not this number is in service.
Judgment is made from the in-service number list shown in (A) (process 602 → judgment 603).

If the received dial-in number is not in service (No in decision 603), the TSI sent from the sender is received by continuing the facsimile reception protocol for a while as in the above embodiment, and the received TSI is received. F
The AX number is extracted and temporarily stored (process 604 → process 605).

After that, a voice message such as "This number is not serviced" is transmitted to the sender, and this communication is temporarily disconnected (process 606 → process 60).
7). Then, the FAX number obtained from the TSI is used to make a call to the sender, and a facsimile message having the same content as the above-mentioned voice message is transmitted as a warning FAX (process 608). A voice message stating that the FAX number to be transmitted is not in service is transmitted from the facsimile machine of the transmission source, and a facsimile message having the same content is recorded and output on the recording paper immediately after the communication is cut off.

On the other hand, if the service is in progress, the TSI is received and recorded in association with the dial-in number and the user ID (Yes in judgment 603 → process 609). The recorded TSI is associated with each number in the non-service telephone number list, as shown in FIG. 9B, when the dial-in number is deallocated and the service is out of service. As shown in FIG. 9C, the “TSI received during the service until the last time” is associated with each user ID in the user ID list, and the “TSI received during the service until the last time” is registered. Registered in the "list", each number will be referred to when it comes back in service.

When the TSI is received and recorded in the processing 609, when the dial-in number is used in the past from the "TSI list received during the previous service" shown in FIG. 9B. Call all TSI of the
10). Then, in the past, it is determined whether or not there is the same TSI that has arrived at that dial-in number. If not, it is not an erroneous incoming call, and the process proceeds to FAX reception (No in decision 611 → process 612). The received facsimile information is stored in the corresponding mailbox, and is transmitted to the corresponding facsimile device 4 in the hotel 1 through the procedure as described in the description of the related art.

On the other hand, if the same TSI has arrived in the past, it is checked whether or not the same user ID has been registered in the past in the user ID list shown in FIG. 9C (determination 611). Yes → judgment 613). If the same user ID has been registered in the past, whether or not there is the same TSI linked to the user ID is determined by the user I.
Check in the "TSI list that arrived during the previous service" associated with D (Yes in judgment 613 →
Decision 614). If they are the same, it means that the incoming call is not a wrong call, and the process proceeds to FAX reception (Yes in determination 614 → process 612).

However, if the same user ID has not been registered in the past, or if there is no same TSI linked to the user ID even if it has been registered in the past, it is an erroneous incoming call, so the TSI originates. After the original FAX number is extracted, the communication is disconnected without shifting to FAX reception (No in judgment 613 → Process 615 → Process 616, or Yes in judgment 613 → No in judgment 614 → Process 615 → Process 616). Then, the FAX number obtained from the TSI is used to make a call to the sender, and a facsimile message indicating that the previous call is a wrong call is transmitted as a warning FAX (step 617). From the source facsimile machine, a facsimile message indicating that there is an incoming call immediately after the communication is cut off and the previous outgoing call is an erroneous incoming call is recorded and output on the recording paper.

By doing so, the same operation and effect as those of the above-described embodiment can be obtained, and it can be surely transmitted to the sender of the wrong incoming call that the wrong incoming call has occurred.
It is possible to prevent repeated false calls.

In the facsimile communication device described above, the facility used by a large number of people has been described as an example of a hotel. However, in addition to the hotel, other facilities such as an inn, a laboratory of a university, and a dormitory It can be applied similarly.
