DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus used on an ISDN line.

[0002]

2. Description of the Related Art Normally, a facsimile apparatus automatically responds to an incoming call and discharges a received document received from a destination onto one discharge tray attached to a side of the apparatus.

In this case, when logarithmic documents are received from a large number of destinations, all the received documents are stacked on the paper discharge tray. Therefore, when a user retrieves a desired document from a large number of received documents, it has been troublesome to find the document.

When an ISDN line is used, a plurality of facsimile machines can be connected to one line.

Now, it is assumed that a call is received from another facsimile apparatus to a line to which a plurality of facsimile apparatuses are connected. At this time, the received call setup message “SET
If the destination sub-address is not specified in "UP", one of the plurality of facsimile machines having the fastest response operation executes the call connection procedure and is transmitted from the other party. Will be received.

Therefore, even if the user receives a message from the transmission source and learns that there is a received document, for example, the user cannot know which facsimile machine is receiving the received document.
For this reason, it is necessary to search for a desired document from the received documents of each device, which is troublesome.

On the other hand, some documents to be transmitted include, for example,
Some documents are important, such as purchase orders from customers, while others are unnecessary, such as advertising.

The conventional facsimile machine unconditionally responds to an incoming call, so that it receives even unnecessary documents, and occupies a communication line for receiving the documents or wastes recording paper. Or was.

A facsimile apparatus is known in which after a communication is started, a destination is confirmed by a special transmission control procedure and a document image is transmitted only in a case of a preset destination. However, since such an operation requires a non-standard transmission control procedure, it can be performed only between specific facsimile machines of a specific manufacturer and is not general.

[0010]

As described above, the conventional facsimile apparatus has a problem that it takes time and effort for a user to retrieve a desired received document, and unnecessary communication is performed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an ISDN facsimile apparatus which can solve the above-mentioned problem, easily retrieve a desired received document, and prevent unnecessary communication.

[0012]

In order to achieve the above object, a facsimile apparatus for ISDN according to the present invention comprises an ISD
N is connected to a plurality of lines connected to the N via a network terminating device, and means for registering a destination facsimile machine which receives a call via the ISDN as a reception accepting destination, and the registration process is performed. Means for notifying the other facsimile apparatus connected to the line of the receiving party who has performed the registration processing, and receiving the notification of the receiving party, rejecting the receiving facsimile apparatus. Means for registering as a destination.

[0013]

[0014]

[0015]

According to the configuration of the present invention, a document transmitted from a specific destination via ISDN to a plurality of facsimile machines connected to a line connected to ISDN via a network terminating device. Even if no sub-address is added, the image is received by one facsimile apparatus in which a specific destination is registered, and can be used as a dedicated terminal directly connected to the specific destination via an independent dedicated line.

Thus, the user can immediately know which of the plurality of facsimile apparatuses connected to the same line receives the desired received document. A desired document can be easily taken out without the trouble of searching for the received document.

[0017] When a reception destination is registered in one facsimile apparatus, the registration information is transferred to another facsimile apparatus and automatically registered as a reception refusal destination. The trouble of registering the destination can be saved.

[0018]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a block diagram of a facsimile communication facility according to a first embodiment of the present invention. In the figure, a facsimile apparatus 1 is a network terminating apparatus 2
Is connected to the ISDN network.

In the facsimile apparatus 1, a scanner 11 reads an image of a document, and a plotter 12
Is for recording an image on recording paper. The encoding / decoding unit 13 compresses the image information to be transmitted while restoring the received compressed data to the original image information. I
The SDN communication unit 14 receives the IS through an unillustrated network termination device.
It is connected to the DN and communicates with other facsimile machines via the ISDN.

The operation display section 15 is used by the user to perform various operations and to display the operation state of the apparatus. The system memory 16 stores information registered in advance in the apparatus. The system control unit 17
This is a microcomputer that monitors and controls each of the above units. The system bus 18 is a signal line for exchanging control signals and various data between the above-described units.

With the above-described configuration, the facsimile apparatus 1 of the present embodiment has a function of registering a receiving reception partner and a reception rejecting partner. The reception destination is a destination that performs call connection and image reception when a call is received. The rejection destination is a destination that does not receive a call and does not receive an image even if a call arrives.

The user performs a registration process of the reception acceptance destination and the reception refusal destination in advance as necessary. In this registration process, as shown in FIG. 2, the ISD of the destination facsimile
Register N address. If the destination is specified per line, register the ISDN address only,
When the designation is made for each destination device, the ISDN number and the subaddress are registered.

This registration processing is executed by a known technique.
The registered information is stored in the system memory 16. In addition,
This registration process need not be executed if it is not necessary.
Further, even in the case of execution, only the reception reception destination or only the reception rejection destination may be registered.

Next, the incoming operation of the facsimile machine 1 will be described.

As shown in FIG. 3, the facsimile apparatus 1 receives a call setting message "SETUP" upon receiving a call (process 101). Then, the “calling number” and “calling subaddress” which are information elements of the received call setting message “SETUP” are read (process 102).

The "calling number" is the ISDN number of the calling facsimile machine, and the "calling subaddress" is the subaddress of the facsimile machine. The “source subaddress” may not be set depending on the situation of the other party.

Next, the facsimile machine 1 determines whether or not the reception destination is registered by the registration processing (step 103). If the reception destination is registered (Y in step 103), the “calling number” and “calling subaddress” received in the call setup message “SETUP” are registered as the reception reception destination. It is determined whether or not there is (process 104).

If the "calling number" and the "calling sub-address" are registered as reception reception destinations (step 10
4), execute a predetermined call connection procedure (process 10).
5) Receive an image transmitted from the other party (Process 10)
6). When the image reception is completed, a predetermined call disconnection procedure is executed (process 107), and the communication is terminated.

On the other hand, if the received "calling number" and "calling sub-address" are not registered as reception reception destinations (N in step 104), the reception rejection destination is registered by the registration processing. (Step 1)
08).

If the reception refusal destination is registered (Y in step 108), it is determined whether the received "calling number" and "calling subaddress" are registered as reception refusal destinations (step 108). Process 109). If the call is registered as a refusal destination (Y in process 109), a call disconnection procedure is immediately executed (process 107), and the communication is terminated.

If it is not registered as a receiving refusal destination (N in process 109), the call is connected and an image is received (to process 105). If the reception destination has not been registered (N in step 103), the processing 10
The same processing is executed from step 8.

As described above, in this embodiment, when an incoming call is received, whether or not to execute image reception is selected based on the registration information. In other words, if neither the receiving recipient nor the rejecting recipient is registered,
As shown in FIG. 4A, the image is always received regardless of the destination. When only the reception destination is registered, the image is received only from the registration destination as shown in FIG. In addition, when only the refusal destination is registered, the image is received only from the destination other than the registered destination as shown in FIG. When both the receiving reception partner and the reception rejecting partner are registered, the image is received only from the receiving reception partner.

Therefore, the user of the facsimile apparatus 1 of the present embodiment, for example, registers a destination to which an important document is transmitted as a reception destination, and receives unnecessary documents from other destinations. Can be prevented. In addition, by registering a destination to which an unnecessary document is transmitted as a reception refusal destination, it is possible to prevent an unnecessary document from being received from the destination. In this way, unnecessary communication can be prevented.

Next, a second embodiment of the present invention will be described.

In this embodiment, as shown in FIG. 5, it is assumed that a plurality of facsimile apparatuses 1 are connected to a bus and connected to an ISDN via a network terminating apparatus 2. The facsimile machine 1 has the same configuration as that of the above-described embodiment.

With this configuration, the user executes the registration process of the reception accepting party and the reception rejecting party with respect to each facsimile machine 1 as necessary, similarly to the above-described embodiment. The registered information is stored in the system memory 16.

By the way, in this embodiment, when a reception reception destination is registered in one of the plurality of facsimile machines 1, the one facsimile machine 1 transfers the registration information to each of the other facsimile machines 1. Perform an action that:

That is, as shown in FIG. 6, it is assumed that the user has executed the registration processing of the reception reception partner for one facsimile machine 1 (processing 201). Then, the facsimile machine 1 calls another facsimile machine 1 and transmits the registered number information. This transmission is performed according to a known procedure of transmitting a call setup message “SETUP” and making a call. Then, the number information to be transmitted is transmitted as, for example, user / user information of the call setup message “SETUP”. Then, the call is disconnected immediately after the transmission is completed (process 202).

When one transmission operation is completed, it is determined whether or not there is another facsimile machine 1 that has not yet transmitted (step 203). If there is another facsimile machine 1 that has not yet transmitted (N in process 203), a similar transmission operation is performed for the corresponding facsimile device 1 (to process 202). When the transmission operation for all the facsimile apparatuses 1 is completed (Y in step 203), one facsimile apparatus 1 on which the registration processing has been executed.
Ends the transfer operation.

On the other hand, each facsimile machine 1 on the receiving side
As shown in FIG. 7, a call is connected to the one facsimile machine, and the number information registered in the facsimile machine is received (process 301). Then, the received number information is stored in the system memory 16 as a reception refusal destination (process 302).

Next, each facsimile apparatus 1 of this embodiment
However, an incoming operation when an incoming call is received from another facsimile machine will be described.

In this case, as shown in FIG. 8, the facsimile machine 1 first receives a call setup message "SETUP" (process 401). The call setup message "SETU
When receiving "P", it is determined whether or not the destination subaddress is set in the message (process 402).
If the destination sub address has been set (Y in step 402), it is further determined whether the destination sub address indicates the sub address of the own apparatus (step 403).
If the sub address of the own device is indicated (process 4
03, Y), and executes a predetermined call connection procedure (process 40).
4) Receive an image transmitted from the other party (process 40)
5). When the image reception is completed, a call disconnection procedure is executed (process 405), and the communication is terminated.

On the other hand, if the destination sub-address is not the sub-address of the own device (N in process 402), no response operation is performed.

Thus, the call setting message "SETU"
When one specific facsimile machine 1 is designated by the destination subaddress of "P", a plurality of facsimile machines 1
Only the corresponding one of them receives an image.

On the other hand, if the destination subaddress is not set in the call setup message “SETUP” (step 4
02, N), the operation is almost the same as in the above-described embodiment. That is, first, the "calling number" and the "calling subaddress" are read (process 407). Then, it is determined whether or not the reception destination is registered (step 408).

When the receiving party is registered (Y in step 408), it is determined whether the received "calling number" and "calling subaddress" are registered as the receiving party. (Process 409). If the "calling number" and the "calling subaddress" are registered as reception reception destinations (Y in process 409), the call is connected and an image is received (to process 404).

On the other hand, if the received "calling number" and "calling sub-address" are not registered as reception reception destinations (N in process 409), it is further determined whether a reception refusal destination is registered. A determination is made (process 410). If the reception refusal destination is registered (Y in process 410), it is determined whether the received “calling number” and “calling subaddress” are registered as the reception refusal destination (process 411). ). If it is registered as a reception refusal destination (Y in process 411), the communication operation ends without performing a response operation.

If it is not registered as a reception refusal destination (N in process 411), the call is connected and an image is received (to process 404). If the reception destination is not registered (N of step 408), the above-mentioned processing 41
The same operation starts from 0.

As described above, in this embodiment, a plurality of facsimile machines 1 having the functions of the above-described embodiment are installed, and a reception acceptance destination and a reception refusal destination are registered in each facsimile device 1. Like that.

Therefore, a receiving apparatus can be set for each transmission source such that a document image transmitted from a specific destination is received by one specific facsimile apparatus 1. In this case, even if a plurality of facsimile machines 1 are connected to one ISDN line, one specific unit becomes easy to use as a dedicated terminal directly connected to a specific destination by an independent dedicated line.

Thus, the user can immediately find out which facsimile machine 1 is receiving the desired received document, so that the user does not have to search for the received document from a large number of received documents of each device as in the related art. A desired received document can be easily taken out without calling.

Further, in this embodiment, when a reception destination is registered in one facsimile apparatus 1, the registration information is transferred to another facsimile apparatus 1 and the other facsimile apparatus 1 automatically receives the registration information as a reception rejection destination. It is to be registered. As a result, the user does not have to register the reception refusal destination in each of the other facsimile machines 1 each time, and can reduce the labor of the registration work.

Next, a third embodiment of the present invention will be described.

In the present embodiment, as shown in FIG. 1, it is assumed that only one facsimile machine 1 is installed.
Then, the plotter 12 of the facsimile machine 1
It is assumed that a paper discharge tray unit 12a having four trays # 0 to # 3 and a paper discharge tray selection unit 12b are attached as shown in FIG. Each of the trays # 0 to # 3 is for placing a received document to be discharged. The discharge tray selection unit 12b selects one of the four trays.

When the facsimile apparatus of this embodiment is used in this configuration, the user can arbitrarily register the correspondence between the ISDN number and each of the trays # 1 to # 3 as shown in FIG. Keep it. This ISDN number is a destination to which an image is transmitted. In addition, one tray # 0 is not registered. This registration process is performed by a known technique, and the registration information is stored in the system memory 16.

Next, the incoming operation of the facsimile apparatus of this embodiment will be described.

As shown in FIG. 11, when the facsimile apparatus receives the call setup message "SETUP" (step 501), it executes a predetermined call connection procedure and receives an image transmitted from the other party (step 501). 502).

Thereafter, it is determined whether or not there is registration information relating to the discharge tray as shown in FIG. 10 (step 50).
3). If there is this registration information (Y in process 503), the “calling number” of the received call setting message “SETUP” is read, and it is determined whether or not the “calling number” is registered (process 504).

If the received "calling number" is registered (Y in step 504), the recording paper on which the received image is recorded is stored in a corresponding one of trays # 1 to # 3 according to the registration information. Is discharged (process 505). On the other hand, if the received “calling number” is not registered (N in process 504), the recording paper is discharged to one tray # 0 (process 5).
06).

As described above, in the present embodiment, the correspondence between the destination ISDN number and each of the trays # 1 to # 3 is registered in advance, and when an incoming call is received and an image is received, it differs for each destination. Since the received document is ejected to the tray, the user can easily retrieve the desired received document because the user can know which tray the desired received document is on.

In the above-described embodiment, the discharge tray is registered in correspondence with only the ISDN number. However, the discharge tray may be registered together with the source sub-address.

[0063]

As described above, according to the present invention, even if a plurality of facsimile apparatuses are connected to a line connected to the ISDN via a network terminating apparatus, the reception destination is registered in one facsimile apparatus. The document image transmitted from the specific destination via the ISDN is received by the single facsimile apparatus even if the subaddress is not added, and the facsimile apparatus becomes independent from the specific destination. It can be used as a dedicated terminal directly connected by a dedicated line.

Further, when a receiving reception destination is registered in one facsimile apparatus, the registration information is transferred to another facsimile apparatus and automatically registered as a reception rejecting destination. The effect of saving the trouble of registering the other party can also be obtained.
