Description

  The present invention relates to a facsimile machine.

  Unwanted advertisements from the same sender may repeatedly arrive at a facsimile machine installed at home or office. If such a nuisance fax arrives frequently, there is a risk of impeding business operations in the office.

  As a countermeasure against annoying fax, the facsimile apparatus is set in advance to register a telephone number of a sender such as an unnecessary advertisement and ignore an incoming call from the registered telephone number (acceptance of incoming call). There is a technique. However, in this incoming call rejection method, the facsimile apparatus continues to receive incoming calls until the transmission source stops calling (transmission of a RING signal), and the line is occupied during that time.

  Therefore, a facsimile apparatus has been proposed that can prevent a line from being occupied by an incoming call by closing the line once and then immediately opening the line for an incoming call from a transmission source registered in advance. (For example, refer to Patent Document 1).

Japanese Patent Laid-Open No. 08-186640

  However, in the facsimile apparatus according to the proposal, the line is once closed and then opened, and facsimile data is not received. Therefore, it is not confirmed that the transmission destination facsimile apparatus has received the image data at the transmission source, and there is a possibility that annoying FAX will be sent again from the transmission source to the facsimile apparatus after the line is opened.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile apparatus capable of shortening the occupation time of a line due to reception of a nuisance FAX while receiving the facsimile data by the nuisance FAX while suppressing re-transmission of the troublesome FAX from the transmission source It is to be.

  In order to achieve the above object, a facsimile apparatus according to an aspect of the present invention is connectable to a telephone line network, and is connected to the other party according to one reception condition among a plurality of reception conditions via the telephone line network. A facsimile communication unit for receiving facsimile data transmitted from the device, a storage unit for storing the other-side device number information, and a control unit. The control unit is connected to the other side via the telephone line network. When the device number information is received, the other party device number determination process for determining whether or not the received counterpart device number information matches the other party device number information, and the other party device number determination process. If it is determined that the device number information on the side matches the device number information on the other side stored in the storage unit, the facsimile data received via the telephone line network among the plurality of reception conditions Information on the reception condition that can be received with the minimum data size is transmitted to the counterpart device, and the counterpart device number information received by the counterpart device number determination process is stored in the storage unit If it is determined that it does not match, the condition transmission process for transmitting to the partner device information on the reception condition that can receive the facsimile data received via the telephone line network with the maximum data size among the plurality of reception conditions And receiving processing for receiving facsimile data transmitted from the counterpart device under a receiving condition equal to or less than the receiving condition transmitted to the counterpart device by the condition transmission processing.

  According to this configuration, when the facsimile communication unit receives the counterpart device number information of the counterpart device, whether or not the received counterpart device number information matches the counterpart device number information stored in the storage unit. Is determined. When the counterpart device number information of the counterpart device matches one of the counterpart device number information stored in the storage unit, the facsimile communication unit can receive the facsimile data with the minimum data size from the counterpart unit. Condition information is sent. Then, the facsimile data transmitted from the counterpart device is received by the facsimile communication unit with the minimum data size.

  On the other hand, if the counterpart device number information of the counterpart device does not match one of the counterpart device number information stored in the storage unit, the facsimile data is transferred from the facsimile communication unit to the counterpart device with the maximum data size. Information on reception conditions that can be received is transmitted. The facsimile communication unit receives the facsimile data transmitted from the counterpart device with the maximum data size.

  The other party apparatus number information of the other party apparatus which is the transmission source of the nuisance FAX is stored in the storage unit, and the facsimile data by the nuisance FAX is normally received even if it is the nuisance FAX from the other party apparatus. For this reason, the partner apparatus that is the sender of the nuisance fax recognizes that the facsimile data is normally received by the destination facsimile apparatus. As a result, it is possible to suppress the nuisance FAX from being transmitted again from the counterpart device in a short time.

  If the counterpart device number information of the counterpart device matches one of the counterpart device number information stored in the storage unit, the facsimile data is not the maximum data size possible in the facsimile device, but the minimum data size. Received in data size. For example, even if the facsimile apparatus has the ability to support color FAX and A3 size FAX, the reception conditions corresponding to monochrome FAX and A4 size FAX are transmitted from the facsimile apparatus to the partner apparatus. Facsimile data is transmitted by facsimile. Therefore, reception of facsimile data can be completed in a short time. As a result, it is possible to shorten the line occupation time due to the reception of the nuisance fax.

  Therefore, by receiving the facsimile data by the nuisance FAX, it is possible to reduce the occupied time of the line due to the reception of the nuisance FAX while suppressing the transmission of the nuisance FAX again from the transmission partner apparatus.

  In the condition transmission process, the control unit may transmit information on a reception condition of receiving facsimile data received via a telephone line network at a maximum communication speed among a plurality of reception conditions to the counterpart apparatus.

  According to this configuration, as for the communication speed, since the maximum speed is transmitted from the facsimile apparatus to the counterpart apparatus, it is possible to further reduce the time required for receiving the facsimile data by the nuisance FAX. As a result, the line occupation time due to the reception of the nuisance FAX can be further shortened.

  The control unit has a start notification reception process for receiving a facsimile transmission start notification from the counterpart device by the facsimile communication unit, and can execute the conditional transmission process regardless of whether the start notification reception process has been executed. Good.

  According to this configuration, the reception condition of the facsimile communication is notified from the facsimile communication unit to the counterpart apparatus without waiting for the reception of the facsimile transmission start notification. As a result, the time required to receive facsimile data can be shortened. As a result, it is possible to further shorten the line occupation time due to the reception of the nuisance fax.

  The control unit has a data storage process in which the facsimile communication unit stores the facsimile data received from the counterpart device in the storage unit, and the facsimile data received via the telephone line network among the plurality of reception conditions by the condition transmission process. Is received at the minimum data size, and the facsimile communication section receives the facsimile data by the reception process, the data storage process need not be executed.

  According to this configuration, even when facsimile data by annoying FAX is received, the facsimile data is not stored. Therefore, it is possible to prevent the storage unit from being pressed by unnecessary facsimile data. Further, it is possible to suppress the formation of an image related to unnecessary facsimile data on the paper, and it is possible to suppress the waste of paper, ink, toner, or the like.

  A line opening / closing unit that opens and closes a telephone line connected to the facsimile communication unit, and when the facsimile communication unit receives the partner device number information of the partner device, the control unit within a predetermined time in the past from the reception , Having a re-reception determination process for determining whether or not the same counterpart apparatus number information as the received counterpart apparatus number information has been received, and the received counterpart apparatus number information is determined by the counterpart apparatus number determination process. When it is determined that it matches the counterpart device number information stored in the storage unit, and by the re-reception determination process, the same counterpart device as the received counterpart device number information within a predetermined past time from reception When the number information is received, the condition transmission process and the reception process are executed, and the partner device number stored in the storage unit is received by the partner device number determination process. If it is determined that it matches the information, and the re-receiving determination process has not received the same counterpart device number information as the received counterpart device number information within a predetermined time in the past from reception, The line opening / closing unit may be kept open.

  When reception of the nuisance fax is permitted by the facsimile apparatus, the nuisance fax is not always sent again from the partner apparatus that is the sender of the nuisance fax. When the nuisance fax is transmitted only once, it takes less time to occupy the line when the incoming of the nuisance fax is permitted than when the image data by the nuisance fax is received.

  According to this configuration, when the facsimile communication unit receives the counterpart device number information of the counterpart device, the counterpart device number that is the same as the received counterpart device number information within the past predetermined time from the reception. It is determined whether information has been received. If the same counterpart apparatus number information has not been received within a predetermined time in the past, the line is not closed between the telephone line network and the facsimile communication unit. That is, an incoming call from the counterpart device is rejected. Thereby, when the nuisance FAX is transmitted only once, the line occupation time due to the reception of the nuisance FAX can be further shortened.

  On the other hand, if the partner device number information of the same partner device is received twice in the past predetermined time, after receiving the second partner device number information between the telephone line network and the facsimile communication unit The line is closed and image data by annoying FAX is received. Therefore, it is possible to prevent the nuisance FAX from being retransmitted thereafter from the counterpart device.

  In the condition transmission process, the control unit sends information on a reception condition that the facsimile apparatus does not have an error correction mode for correcting an error of the facsimile data received by the facsimile communication unit among the plurality of reception conditions to the counterpart apparatus. You may send it.

  When the facsimile data is received from the counterpart device of the counterpart device number information stored in the storage unit, the received facsimile data is unnecessary facsimile data. Therefore, there is no problem even if there is an error in the received facsimile data. For this reason, error correction mode, for example, ECM (Error Correction Mode) is transmitted to the other side device to the effect that the facsimile device is not equipped, so that error correction is not performed. As a result, it is possible to prevent the line from being occupied due to the re-reception of the facsimile data having an error, and it is possible to further shorten the line occupation time due to the reception of the nuisance FAX.

  According to the present invention, by receiving facsimile data by a nuisance FAX, it is possible to reduce the occupied time of the line due to the reception of the nuisance FAX while suppressing the transmission of the nuisance FAX again from the transmission source.

It is a flowchart which shows the flow of a FAX process. It is a flowchart which shows the flow of a 2nd FAX process.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Overall configuration>

  As illustrated in FIG. 1, the MFP 1 as an example of a facsimile apparatus includes an image forming unit 10, an image reading unit 20, and a modem unit 30 as an example of a facsimile communication unit.

  The image forming unit 10 performs printing (color printing or monochrome printing) based on image data, and forms an image on a sheet. The image forming method may be an electrophotographic method or an inkjet method.

  The image reading unit 20 reads an image formed on the sheet from the sheet and acquires it as image data.

  The modem unit 30 is connected to a modular jack 31. The modem unit 30 is connected to the public line network by inserting a modular cable 41 as an example of a telephone line connected to the exchange 40 into the modular jack 31.

  The modem unit 30 includes a line switching circuit 32 as an example of a line switching unit.

  The line switching circuit 32 switches between opening and closing the connection between the modular jack 31 and the modem unit 30. When the line switching circuit 32 is closed, the modular jack 31 and the modem unit 30 are connected. When the line opening / closing circuit 32 is open, the connection between the modular jack 31 and the modem unit 30 is released.

  The MFP 1 includes an application specific integrated circuit (ASIC) 50, a ROM 51, a RAM 52, a non-volatile RAM (NVRAM) 53, and a speaker 60.

  An ASIC 50 as an example of a control unit includes a CPU 54 and a sound output circuit 55. Facsimile communication data transmitted / received to / from the exchange 40 is input / output to / from the ASIC 50 via the modem unit 30. The CPU 54 executes programs for various processes based on information input to the ASIC 50 to control the image forming unit 10 and the image reading unit 20 and to control communication via the modem unit 30.

  The sound output circuit 55 causes the speaker 60 to output sounds corresponding to various signals related to fax communication received by the modem unit 30. When the received signal is a sound signal, the sound output circuit 55 outputs the sound by outputting the signal to the speaker 60 as it is. In addition, when the received signal is not a sound signal, the sound output circuit 55 synthesizes a sound signal corresponding to the received signal and outputs the sound synthesis signal to the speaker 60, thereby causing the sound to be output. Thus, for example, when a RING signal is received, a bell sound is synthesized by the sound output circuit 55, a sound synthesis signal (bell sound) is transmitted from the sound output circuit 55 to the speaker 60, and a bell sound is output from the speaker 60. Is done.

  The ROM 51 stores a program executed by the CPU 54 and various data.

  A RAM 52 as an example of a storage unit is used as a work area when the CPU 54 executes a program.

  The NVRAM 53 as an example of the storage unit stores a telephone number as an example of the counterpart device number information.

  The MFP 1 includes a modular jack 71 for connecting the external telephone 70 to the MFP 1 and a telephone connection relay 80.

  The telephone connection relay 80 switches between opening and closing the connection between the modular jack 71 and the modular jack 31. When the telephone connection relay 80 is in the closed state, the exchange 40 and the external telephone 70 are connected. When the telephone connection relay 80 is open, the connection between the exchange 40 and the external telephone 70 is released.

<Sound control processing>

  While the MFP 1 is powered on, the CPU 54 of the ASIC 50 repeatedly executes the troublesome FAX control process shown in FIGS. 2A and 2B.

  In the nuisance FAX control process, when there is an incoming call, the CPU 54 determines whether or not a CallerID as an example of the counterpart device number information is input to the call signal (S1).

  When the Caller ID is input (S1: YES), the CPU 54 determines whether or not the telephone number specified by the Caller ID matches the telephone number stored in the NVRAM 53 (S2). The NVRAM 53 stores a list of telephone numbers of senders of unwanted faxes.

  When the telephone number specified by the CallerID does not match the telephone number stored in the NVRAM 53 (S2: NO), the CPU 54 turns on the monitor of the modem unit 30 and turns off the mute of the speaker 60, whereby the FAX number is set. Alternatively, output of the telephone ringing tone is permitted (S3).

  On the other hand, when the Caller ID is not input (S1: NO), the CPU 54 turns on the monitor of the modem unit 30 and turns off the mute of the speaker 60, thereby permitting the output of the FAX or telephone ringing tone ( S3).

  Then, the CPU 54 receives one RING signal (S4).

  The CPU 54 causes the speaker 60 to ring a bell sound by passing the received RING signal through the sound output circuit 55 and inputting it to the speaker 60 (S5).

  Next, the CPU 54 determines whether or not the number of received RING signals has reached a predetermined number (S6).

  When the number of received RING signals has not reached the predetermined number (S6: NO), the CPU 54 returns to the process of step S4 described above and receives the next one RING signal.

  When the number of RING signals received reaches a predetermined number (S6: YES), the CPU 54 closes the line by instructing the modem part 30 to close the line opening / closing circuit 32 of the modem part ( S7).

  Then, the CPU 54 determines whether or not the reception is FAX (S8).

  When the reception is FAX (S8: YES), the CPU 54 executes FAX processing (S9) and ends the troublesome FAX control processing. Details of the FAX processing will be described later.

  When the reception is not FAX (S8: NO), the CPU 54 determines whether or not a predetermined time T1 has elapsed since the reception of the first RING signal (S10).

  When the predetermined time T1 has not elapsed (S10: NO), the CPU 54 returns to the process of step S8 described above and determines whether or not the reception is FAX.

  If the predetermined time T1 has elapsed (S10: YES), that is, if it is not determined that the reception is a FAX even after the predetermined time T1 has elapsed, it is considered that the reception is a telephone call. (S11). In the telephone connection process, the telephone connection relay 80 is switched to the closed state, and the external telephone is connected to the public line network.

  On the other hand, if the telephone number specified by the CallerID matches the telephone number stored in the NVRAM 53 (S2: YES), that is, the partner apparatus in which the telephone number is stored in the NVRAM 53 as the sender of the nuisance FAX CPU 54 turns off the monitor of modem unit 30 and turns on mute of speaker 60, thereby prohibiting the output of FAX or telephone ringing tone (S12).

  Then, the CPU 54 receives one RING signal (S13).

  Next, the CPU 54 determines whether or not the number of received RING signals has reached a predetermined number (S14).

  If the number of received RING signals has not reached the predetermined number (S14: NO), the CPU 54 returns to the process of step S13 described above and receives the next one RING signal.

  When the reception number of the RING signal reaches a predetermined number (S14: YES), the CPU 54 determines whether or not there is reception from the same Caller ID transmission source within a predetermined time in the past from the reception of the RING signal. It is determined whether or not there has been two or more receptions within a predetermined time in the past from a partner apparatus whose telephone number is stored in the NVRAM 53 as the sender of the nuisance fax (S15). The CPU 54 stores the received Caller ID in the RAM 52 until a predetermined time has elapsed since the reception of the RING signal.

  When receiving from the same Caller ID transmission source (S15: YES), the CPU 54 closes the line by instructing the modem part to close the line opening / closing circuit 32 of the modem part 30 ( S16).

  Then, the CPU 54 executes a second FAX process (S17). Details of the second FAX processing will be described later.

  On the other hand, when there is no reception from the transmission source of the same Caller ID (S15: NO), the CPU 54 ends the troublesome FAX control process. As a result, incoming calls are rejected by not closing the line.

<FAX processing>

  The flow of FAX processing executed in step S9 in FIG. 2B is shown in FIG.

  In the FAX processing, the CPU 54 causes the modem unit 30 to send a fax message indicating that the FAX is to be received to the counterpart device using the CED signal, and then causes the modem unit 30 to transmit the maximum FAX function of the MFP 1 to the counterpart side using the DIS signal. Transmission is performed toward the apparatus (S901). The maximum FAX function is, for example, that the document width is A3 size according to JIS standard, color FAX is possible, and ECM is possible.

  The CPU 54 determines whether or not the modem unit 30 has received the FAX transmission instruction (CNG signal) from the counterpart device (S902: NO) (S902).

  When the FAX transmission instruction is received (S902: YES), the CPU 54 causes the modem unit 30 to start receiving the image signal from the counterpart device. Further, the CPU 39 starts saving image data in the RAM 52 using the received image signal (S903).

  Then, the CPU 54 waits for the end of the reception (S904) until the reception of the image signal ends (S904: NO).

  When reception of the image signal is completed (S904: YES), the CPU 54 instructs the modem unit 30 to open the line opening / closing circuit 32 of the modem unit, thereby opening the line (S905), and FAX processing. To return.

<Second FAX processing>

  The flow of the second FAX process executed in step S17 of FIG. 2A is shown in FIG.

  In the second FAX process, the CPU 54 causes the modem unit 30 to send a fax message indicating that the FAX is to be received to the counterpart device using the CED signal, and then causes the modem unit 30 to send the minimum FAX function of the MFP 1 to the counterpart device using the DIS signal. Transmission is performed toward the side device (S1701). The minimum FAX function is, for example, that the document width is A4 size according to JIS standard, color FAX is not possible, communication speed is maximum, and ECM is not possible.

  The CPU 54 determines whether or not the modem unit 30 has received a fax transmission instruction (CNG signal) from the counterpart device (S1702: NO) (S1702).

  When a FAX transmission instruction is received (S1702: YES), the CPU 54 causes the modem unit 30 to start receiving an image signal from the counterpart device (S1703). However, the CPU 39 does not store the image data based on the received image signal in the RAM 52.

  The CPU 54 waits for the end of the reception (S1704) until the reception of the image signal is completed (S1704: NO).

  When reception of the image signal is completed (S1704: YES), the CPU 54 instructs the modem unit 30 to open the line opening / closing circuit 32 of the modem unit 30, thereby opening the line (S1705). Returns 2FAX processing.

<Effect>

  As described above, when the modem unit 30 receives the CallerID of the counterpart device in facsimile communication, it is determined whether or not the telephone number specified by the received CallerID matches the telephone number stored in the NVRAM 53. . When the telephone number of the partner apparatus matches one of the telephone numbers stored in NVRAM 53, information on reception conditions that can receive facsimile data with the minimum data size is transmitted from modem unit 30 to the partner apparatus. . Then, the modem unit 30 receives facsimile data transmitted from the counterpart device with a minimum data size.

  On the other hand, if the telephone number of the partner apparatus does not match one of the telephone numbers stored in the NVRAM 53, information on reception conditions that can receive facsimile data from the modem unit 30 to the partner apparatus with the maximum data size. Is sent. Then, the modem unit 30 receives the facsimile data transmitted from the counterpart device with the maximum data size.

  The telephone number of the partner device that is the sender of the nuisance fax is stored in the NVRAM 35, and even if it is a nuisance fax from the partner device, the facsimile data by the nuisance fax is normally received. For this reason, the counterpart apparatus that is the sender of the nuisance fax recognizes that the facsimile data has been normally received by the destination MFP 1. As a result, it is possible to suppress the nuisance FAX from being transmitted again from the counterpart device in a short time.

  If the telephone number of the partner apparatus matches one of the telephone numbers stored in NVRAM 53, the facsimile data is received with the minimum data size, not the maximum data size possible with MFP1. For example, even if the MFP 1 has the ability to support color FAX and A3 size FAX, the MFP 1 transmits a reception condition corresponding to the monochrome FAX and A4 size FAX to the partner apparatus, and facsimile data is received under the reception condition. Is transmitted by facsimile. Therefore, reception of facsimile data can be completed in a short time. As a result, it is possible to shorten the line occupation time due to the reception of the nuisance fax.

  Therefore, by receiving the facsimile data by the nuisance FAX, it is possible to reduce the occupied time of the line due to the reception of the nuisance FAX while suppressing the transmission of the nuisance FAX again from the transmission partner apparatus.

  The ASIC 50 transmits information on the reception condition that the facsimile data received via the telephone line network is received at the maximum communication speed among the plurality of reception conditions to the counterpart apparatus.

  As a result, the maximum communication speed is transmitted from the MFP 1 to the partner apparatus, so that it is possible to further reduce the time required for receiving facsimile data by the nuisance FAX. As a result, the line occupation time due to the reception of the nuisance FAX can be further shortened.

  The ASIC 50 stores the facsimile data received by the modem unit 30 from the counterpart device in the RAM 52. Among the plurality of reception conditions, when the facsimile data received via the telephone line network is received with the minimum data size, the reception condition information is transmitted to the counterpart device, and the modem unit 30 receives the facsimile data. The facsimile data received from the device on the other hand side is not stored in the RAM 52.

  As a result, even if facsimile data by annoying FAX is received, the facsimile data is not saved. Therefore, it is possible to prevent the RAM 52 from being compressed by unnecessary facsimile data. Further, it is possible to suppress the formation of an image related to unnecessary facsimile data on the paper, and it is possible to suppress the waste of paper, ink, toner, or the like.

  The ASIC 50 includes a line opening / closing circuit that opens and closes a telephone line connected to the modem unit 30. When the modem unit 30 receives the CallerID of the counterpart device, the received CallerID is received within a predetermined time in the past from the reception. If the received CallerID matches the telephone number stored in the NVRAM 53, and within the predetermined time in the past from the reception, the received CallerID and the same CallerID are determined. When the same Caller ID is received, information on the reception condition that can receive the facsimile data with the minimum data size is transmitted to the other device, and the facsimile data is received with the minimum data size from the partner device. . When it is determined that the telephone number specified by the received CallerID matches the telephone number stored in the NVRAM 53, and the same CallerID as the received CallerID has not been received within the predetermined time in the past from the reception. In that case, the line switching circuit 32 is kept open.

  Thereby, when the modem unit 30 receives the CallerID of the counterpart device, it is determined whether or not the same CallerID as the received CallerID has been received within a predetermined time in the past from the reception. When the same Caller ID has not been received within a predetermined past time, the line is not closed between the telephone line network and the modem unit 30. That is, an incoming call from the counterpart device is rejected. Thereby, when the nuisance FAX is transmitted only once, the line occupation time due to the reception of the nuisance FAX can be further shortened.

  On the other hand, if the CallerID of the same counterpart device is received twice within a predetermined time in the past, the line is closed between the telephone line network and the modem unit 30 after the second CallerID is received, and annoying FAX Is received. Therefore, it is possible to prevent the nuisance FAX from being retransmitted thereafter from the counterpart device.

  The ASIC 50 transmits information on a reception condition that the facsimile apparatus does not have an ECM for correcting an error of facsimile data received by the modem unit 30 among a plurality of reception conditions to the counterpart apparatus.

  When the facsimile data is received from the counterpart device having the telephone number stored in the NVRAM 53, the received facsimile data is unnecessary facsimile data. Therefore, there is no problem even if there is an error in the received facsimile data. Therefore, error correction is not performed by transmitting to the counterpart apparatus that the MFP 1 does not have an ECM. As a result, it is possible to prevent the line from being occupied due to the re-reception of the facsimile data having an error, and it is possible to further shorten the line occupation time due to the reception of the nuisance FAX.

<Modification>

  As mentioned above, although embodiment of this invention was described, this invention can also be implemented with another form.

  For example, the ASIC 50 may transmit a DIS signal to the counterpart device regardless of whether or not a CNG signal is received.

  As a result, the receiving condition of the facsimile communication is notified from the modem unit 30 to the counterpart device without waiting for the reception of the facsimile transmission start notification (CNG signal). As a result, the time required to receive facsimile data can be shortened. As a result, it is possible to further shorten the line occupation time due to the reception of the nuisance fax.

  Further, a fax machine may be used instead of the MFP 1.

  In addition, various design changes can be made to the above-described configuration within the scope of the matters described in the claims.
