Description

  The present invention relates to a facsimile apparatus that uses an IP (Internet Protocol) address for facsimile communication.

  Facsimile communication using an analog telephone line such as a G3 facsimile is widely used, but in recent years, facsimile communication using a mail address and facsimile communication using an IP address have become widespread due to the development of the Internet and intranets. .

  The facsimile apparatus has a function of notifying its own station number. The function of notifying the local station number is that the facsimile number set in the facsimile machine (local station number) is registered in advance in the facsimile machine so that when the facsimile machine sends a facsimile, This is a function for notifying the destination facsimile machine of the number.

  In other words, this function is used when a facsimile sent from a partner facsimile machine is received because the facsimile number set in the partner facsimile machine is registered in advance in the partner facsimile machine. In addition, the local station number of the destination facsimile apparatus is notified.

  The facsimile apparatus has a reception refusal function. The reception refusal function is used to register a facsimile number set for a destination facsimile machine that does not want to receive a facsimile in advance, thereby receiving a facsimile transmitted from the destination facsimile machine. It is a function to reject.

  There is a problem with a facsimile (junk fax) for the purpose of advertising that is sent unilaterally without notice.

  As a facsimile machine that can refuse to receive junk faxes, when receiving a facsimile with the partner operator confirmed, or when receiving a facsimile without confirming the partner operator without operating the direct mail prevention means A technique for operating the direct mail prevention means has been proposed (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 6-6561

  If the other party's facsimile machine that sends the junk fax reports its own station number, that number will be rejected. Therefore, the other party's facsimile machine has its own station number intentionally registered. Absent. Such a destination facsimile apparatus transmits a facsimile without notifying its own station number.

  Therefore, the reception rejection function includes a function of rejecting reception of a facsimile transmitted without notifying its own station number.

  Since the facsimile communication is possible even if the own station number is not registered in the facsimile apparatus, the registration of the own station number may be forgotten.

  When a facsimile is sent from such a destination facsimile machine, if the facsimile machine is set to refuse reception of a facsimile sent without notifying its own station number, the facsimile machine does not receive the facsimile. I refuse. That is, in order to refuse the reception of junk fax, by setting to reject the reception of the facsimile transmitted without notifying the own station number, the facsimile to be originally received cannot be received.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile apparatus that can receive a facsimile transmitted from a partner apparatus that has forgotten to register its own station number while refusing to receive a junk fax.

  FIG. 2 is a block diagram showing a configuration of the image forming apparatus 1 shown in FIG. The image forming apparatus 1 has a configuration in which an apparatus main body 100, a document reading unit 200, a document feeding unit 300, an operation unit 400, a control unit 500, and a communication unit 600 are connected to each other by a bus. Since the apparatus main body 100, the document reading unit 200, the document feeding unit 300, and the operation unit 400 have already been described, description thereof will be omitted.

  The communication unit 600 is connected to an unspecified number of destination apparatuses 3 via an IP (Internet Protocol) network 5. The destination apparatus 3 is an apparatus having a facsimile function, for example, a facsimile machine, a multifunction machine having a facsimile function, and a personal computer having a facsimile function.

  The communication unit 600 performs facsimile communication with the counterpart device 3 using SIP (Session Initiation Protocol) and the IP network 5. As described above, the image forming apparatus 1 according to the present embodiment uses an IP (Internet Protocol) address for facsimile communication. That is, the communication unit 600 receives a facsimile transmitted from the partner apparatus 3 using the IP address set in the partner apparatus 3 and the IP address set in the image forming apparatus 1. A facsimile is transmitted to the destination apparatus 3. In addition, the communication unit 600 performs telephone communication with the counterpart device 3 using the SIP and the IP network 5.

  The control unit 500 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an image memory, and the like. The CPU executes control necessary for operating the image forming apparatus 1 for the above-described components of the image forming apparatus 1 such as the apparatus main body 100. The ROM stores software necessary for controlling the operation of the image forming apparatus 1. The RAM is used for temporary storage of data generated during execution of software, storage of application software, and the like. The image memory temporarily stores image data (image data output from the document reading unit 200, image data received by facsimile, etc.).

  The control unit 500 includes a reception mode execution unit 501, an IP address acquisition unit 503, an IP address registration unit 505, a reception rejection setting unit 507, and a reception rejection processing unit 509 as functional blocks.

  The reception mode execution unit 501 selectively executes an automatic reception mode and a manual reception mode. The automatic reception mode is a mode in which when the counterpart apparatus 3 transmits a facsimile to the image forming apparatus 1, the communication unit 600 of the image forming apparatus 1 automatically receives the facsimile. The manual reception mode is a mode in which the communication unit 600 of the image forming apparatus 1 receives a facsimile transmitted from the counterpart apparatus 3 when the user of the image forming apparatus 1 operates the operation unit 400.

  The reception mode execution unit 501 executes the automatic reception mode if the user operates the operation unit 400 to set the facsimile reception mode to the automatic reception mode, and if the user sets the manual reception mode, the manual reception mode. Execute.

  There are two modes of manual reception. First, after the user of the image forming apparatus 1 has a conversation with the user of the counterpart apparatus 3 over the telephone and confirms the intention to perform facsimile communication, the user of the counterpart apparatus 3 performs an operation of transmitting a facsimile, and This is a mode in which the communication unit 600 receives a facsimile when the user of the image forming apparatus 1 receives the facsimile (manual call reception). The other is an operation for receiving a facsimile when the user of the image forming apparatus 1 hears a so-called “Piechoro sound”, that is, a CED (called) signal without having a telephone conversation with the user of the counterpart apparatus 3. Thus, the communication unit 600 receives a facsimile (non-call manual reception).

  An IP address acquisition unit 503, an IP address registration unit 505, a reception rejection setting unit 507, and a reception rejection processing unit 509 are functional blocks that implement a facsimile reception rejection function.

  The IP address acquisition unit 503 uses the SIP and IP network 5 between the communication unit 600 and the partner device 3 to perform IP communication that is set in the partner device 3 when facsimile communication or telephone communication is performed. Get the address. Accordingly, the IP address acquisition unit 503 acquires the IP address set in the counterpart apparatus 3 when the counterpart apparatus 3 transmits a facsimile to the image forming apparatus 1.

  In the IP address registration unit 505, the IP address set in the counterpart apparatus 3 to which the communication unit 600 should receive a facsimile is registered in advance. The IP address registration unit 505 registers the IP address acquired by the IP address acquisition unit 503 when a predetermined condition is satisfied.

  In the reception refusal setting unit 507, when the user of the image forming apparatus 1 operates the operation unit 400, the first reception refusal setting or the second reception refusal setting is performed.

  The first reception refusal setting is performed when the user of the image forming apparatus 1 operates the operation unit 400 to input a facsimile number set in the partner apparatus 3 that does not want to receive a facsimile. 3 is a setting that causes the communication unit 600 to reject the reception of the facsimile transmitted from 3.

  In the second reception rejection setting, the facsimile number set in the partner apparatus 3 is not notified to the image forming apparatus 1 and the facsimile (transmitted facsimile whose own station number is not notified) transmitted from the partner apparatus 3 is notified. Thus, the communication unit 600 is set to reject the reception.

  When the first reception rejection setting is made, the reception rejection processing unit 509 performs the first reception rejection processing in the automatic reception mode. More specifically, the reception rejection processing unit 509 sets the facsimile number set in the partner apparatus 3 that transmits a facsimile to the image forming apparatus 1 in the reception rejection setting unit 507 in the automatic reception mode. Judge whether or not. If the facsimile number is set in the reception rejection setting unit 507, the reception rejection processing unit 509 causes the communication unit 600 to reject reception of the facsimile. On the other hand, if the facsimile number is not set in the reception rejection setting unit 507, the reception rejection processing unit 509 causes the communication unit 600 to receive the facsimile.

  When the second reception rejection setting is made, the reception rejection processing unit 509 performs the second reception rejection process in the automatic reception mode. More specifically, as described above, the IP address acquisition unit 503 acquires the IP address set in the counterpart apparatus 3 when the counterpart apparatus 3 transmits a facsimile to the image forming apparatus 1. The reception rejection processing unit 509 transmits a facsimile to the image forming apparatus 1 without notifying the image forming apparatus 1 of the facsimile number set in the counterpart apparatus 3 in the automatic reception mode. At this time, it is determined whether or not an IP address that matches the IP address acquired by the IP address acquisition unit 503 is registered in the IP address registration unit 505.

  If it is determined that the IP address that matches the IP address acquired by the IP address acquisition unit 503 is not registered in the IP address registration unit 505, the reception rejection processing unit 509 causes the communication unit 600 to reject facsimile reception, If it is determined that it is registered, the communication unit 600 receives the facsimile.

  An operation for registering the IP address set in the counterpart apparatus 3 in the IP address registration unit 505 will be described. FIG. 3 is a flowchart for explaining the operation. The image forming apparatus 1 and the counterpart apparatus 3 perform telephone communication and facsimile communication using SIP and the IP network 5 shown in FIG.

  The reception rejection setting unit 507 has a second reception rejection setting (step S1). As described above, the second reception refusal setting is a setting for refusing reception of a facsimile that does not notify its own station number. The first reception rejection setting may or may not be made in the reception rejection setting unit 507. As described above, the first reception rejection setting is a setting for rejecting reception of a facsimile transmitted from the destination apparatus 3 having a specific facsimile number.

  The reception mode execution unit 501 executes the manual reception mode (step S2).

  When the user of the counterpart apparatus 3 makes a call to the user of the image forming apparatus 1 using SIP, the communication unit 600 receives the INVITE request from the counterpart apparatus 3. The IP address acquisition unit 503 acquires the IP address set in the counterpart device 3 included in the INVITE request (step S3).

  After receiving the INVITE request, communication unit 600 determines whether a SIP session has been established between communication unit 600 and counterpart device 3 (step S4). That is, the communication unit 600 determines whether the user of the image forming apparatus 1 has received a call from the user of the counterpart apparatus 3.

  When the SIP session is not established between the communication unit 600 and the partner apparatus 3 (No in step S4), that is, the user of the image forming apparatus 1 receives a call from the user of the partner apparatus 3. If not, the process returns to step S2.

  When a SIP session is established between the communication unit 600 and the partner apparatus 3 (Yes in step S4), that is, when the user of the image forming apparatus 1 receives a call from the user of the partner apparatus 3, Proceed to step S5.

  In step S5, the communication unit 600 performs telephone communication with the counterpart device 3. In this telephone communication, a conversation is held between the user of the counterpart apparatus 3 and the user of the image forming apparatus 1. That is, the user of the counterpart apparatus 3 informs the user of the image forming apparatus 1 by telephone that a facsimile will be transmitted. If voice data is exchanged between the communication unit 600 and the counterpart device 3, the communication unit 600 can determine that a conversation has occurred.

  The user of the partner apparatus 3 operates the partner apparatus 3 to transmit a facsimile from the partner apparatus 3 to the image forming apparatus 1 using the SIP and IP network 5 (step S6).

  When the user of the image forming apparatus 1 operates the operation unit 400, the communication unit 600 receives the facsimile transmitted in step S6 (step S7).

  The communication unit 600 determines whether or not the facsimile received in step S7 is a facsimile not reporting its own station number (step S8). That is, it is determined whether or not the facsimile apparatus has transmitted the image forming apparatus 1 to the image forming apparatus 1 without notifying the image forming apparatus 1 of the facsimile number set in the counterpart apparatus 3.

  When the communication unit 600 determines that the local station number is not notified (Yes in step S8), the IP address registration unit 505 registers the IP address acquired by the IP address acquisition unit 503 in step S3 (step S9). .

  On the other hand, when the communication unit 600 does not determine that the local station number is not notified (No in step S8), the IP address registration unit 505 registers the IP address acquired by the IP address acquisition unit 503 in step S3. No (step S10). If the facsimile is not notified of its own station number, the facsimile number set in the partner apparatus 3 is notified to the image forming apparatus 1, and the partner apparatus 3 transmits a facsimile to the image forming apparatus 1. It is.

  The IP address registered in step S9 is used in a process (second reception refusal process) in which the image forming apparatus 1 does not receive a facsimile whose own station number is not notified.

  The second reception rejection process will be described. FIG. 4 is a flowchart for explaining the operation. The reception refusal setting unit 507 has a setting (second reception refusal setting) for refusing reception of a facsimile not notified by its own station number (step T1). The first reception rejection setting may or may not be made in the reception rejection setting unit 507.

  The reception mode execution unit 501 is executing the automatic reception mode (step T2).

  Communication unit 600 determines whether or not a facsimile transmission has been received from partner apparatus 3 (step T3). SIP and IP network 5 are used for this facsimile transmission.

  When the communication unit 600 does not determine that facsimile transmission has been received from the counterpart device 3 (No in step T3), step T3 is repeated.

  When communication unit 600 determines that a facsimile transmission has been received from counterpart device 3 (Yes in step T3), communication unit 600 receives an INVITE request from counterpart device 3. The IP address acquisition unit 503 acquires the IP address set in the counterpart device 3 included in the INVITE request (step T4).

  The reception refusal processing unit 509 determines whether or not the facsimile transmitted in step T3 is a facsimile that does not notify its own station number (step T5).

  When the reception rejection processing unit 509 determines that the facsimile is not notified of its own station number (Yes in step T5), an IP address that matches the IP address set in the counterpart device 3 is registered in the IP address registration unit 505. It is determined whether or not it has been performed (step T6). That is, the reception rejection processing unit 509 determines whether or not an IP address that matches the IP address acquired in step T4 is registered in the IP address registration unit 505.

  When the reception rejection processing unit 509 determines that the IP address that matches the IP address acquired in step T4 is registered in the IP address registration unit 505 (Yes in step T6), the reception rejection processing unit 509 transmits the communication unit 600 to the communication unit 600 in step T3. The received facsimile is received (step T7).

  If the IP address matching the IP address acquired in step T4 is not registered in the IP address registration unit 505 (No in step T6), the reception rejection processing unit 509 transmits to the communication unit 600 in step T3. The received facsimile is rejected (step T8).

  When the reception refusal processing unit 509 does not determine that the local station number is not notified (No in step T5), that is, notifies the facsimile number set in the partner apparatus 3 to the image forming apparatus 1, and When the apparatus 3 transmits a facsimile to the image forming apparatus 1, the communication unit 600 receives the facsimile transmitted in step T3 (step T7).

  The main effects of this embodiment will be described. In facsimile communication that uses an IP address for facsimile communication, such as facsimile communication using SIP, when the partner apparatus 3 transmits a facsimile, the IP address set in the partner apparatus 3 is notified. The The image forming apparatus 1 according to the present embodiment uses this to determine whether or not it is a junk fax when a facsimile without a local station number is transmitted.

  More specifically, referring to FIG. 4, if the facsimile transmitted from destination apparatus 3 is a facsimile whose own station number is not notified (Yes in step T5), the IP address set in destination apparatus 3 It is determined whether or not an IP address that matches is registered in the IP address registration unit 505 (step T6). If the IP address that matches the IP address set in the counterpart device 3 is not registered in the IP address registration unit 505 (No in step T6), the communication unit 600 rejects facsimile reception (step T8). If registered (Yes in step T6), the communication unit 600 receives the facsimile (step T7).

  Therefore, even when the reception rejection setting unit 507 is set to reject the reception of the facsimile without notification of the own station number (second reception rejection setting), the image forming apparatus 1 (communication unit 600) receives the facsimile. If the IP address set for the destination apparatus 3 is registered in advance in the IP address registration unit 505 (for example, step S9 in FIG. 3), the image forming apparatus 1 of the destination apparatus 3 to which the facsimile apparatus should receive the facsimile. Even if the user forgets to register his / her own station number, the image forming apparatus 1 receives a facsimile from the partner apparatus 3. Therefore, according to the image forming apparatus 1 according to the present embodiment, it is possible to receive a facsimile transmitted from the partner apparatus 3 that has forgotten to register its own station number while rejecting the reception of the junk fax.

  In the present embodiment, which IP address is registered in the IP address registration unit 505 among the IP addresses set in an unspecified number of destination devices 3 is determined as follows. Referring to FIG. 3, processing (a) and processing (b) are performed in a state where a SIP session is established between communication unit 600 and counterpart device 3 (Yes in step S4).

  Process (a) is as follows. The communication unit 600 performs telephone communication (step S5), and the facsimile number set in the partner apparatus 3 is not notified to the image forming apparatus 1, and is transmitted from the partner apparatus 3 in the manual reception mode. When receiving an incoming facsimile (when receiving a facsimile with no local number notification: Yes in step S8), the IP address registration unit 505 registers the IP address acquired by the IP address acquisition unit 503 in step S3 (step S8). S9).

  Process (b) is as follows. The communication unit 600 performs telephone communication (step S5), and the facsimile number set in the partner apparatus 3 is notified to the image forming apparatus 1 and transmitted from the partner apparatus 3 in the manual reception mode. When the incoming facsimile is received (No in step S8), the IP address registration unit 505 does not register the IP address acquired by the IP address acquisition unit 503 in step S3 (step S10).

  The user of the partner apparatus 3 notifies the user of the image forming apparatus 1 that a facsimile is to be transmitted by telephone (step S5), and the facsimile transmitted from the partner apparatus 3 is received in the manual reception mode (step S5). S6, S7). In this case, since the facsimile transmitted by the partner apparatus 3 is not a junk fax, the image forming apparatus 1 can receive the facsimile transmitted from the partner apparatus 3 from now on even if it is a facsimile whose own station number is not notified. It is necessary to do so.

  Therefore, as described in the process (a), the IP address set in the counterpart device 3 is registered in the IP address registration unit 505 (step S9). As a result, the image forming apparatus 1 can receive the facsimile from now on even if the facsimile apparatus to which the destination apparatus 3 is transmitted is a facsimile whose own station number is not notified (Yes in step T5 in FIG. 4). In step T6 of FIG. 4, Yes, step T7).

  On the other hand, as described in the process (b), if it is not a facsimile that does not notify its own station number in step S8, that is, if the destination apparatus 3 notifies the own station number and transmits a facsimile, that destination The IP address set in the device 3 is not registered in the IP address registration unit 505 (step S10). If the facsimile transmitted from the destination apparatus 3 is not a facsimile not notified by the own station number, a setting for rejecting reception of the facsimile not notified by the own station number (second reception rejection setting) is set in the reception rejection setting unit 507. This is because a facsimile transmitted from the destination apparatus 3 can be received even if the communication is performed. Therefore, the IP address is not registered in the IP address registration unit 505 (step S10). Thereby, since the IP addresses registered in the IP address registration unit 505 can be narrowed down, the memory capacity of the IP address registration unit 505 can be reduced.

  Further, according to the present embodiment, the reception rejection processing unit 509 rejects the reception of the facsimile not notified of its own station number in the automatic reception mode (step T2 in FIG. 4) (second reception rejection processing). ) And do not process in manual reception mode. This is because in the manual reception mode, the user of the image forming apparatus 1 can refuse to receive a junk fax by not performing an operation of receiving a facsimile.
