Description

  The present invention relates to a facsimile apparatus that automatically receives a call and receives facsimile data.

  Conventionally, a technique related to a facsimile apparatus has been proposed (see, for example, Patent Document 1). Patent Document 1 discloses a facsimile apparatus having an automatic reception mode for automatically starting reception of a facsimile when a predetermined number of ringing rings at the time of an incoming call and the handset is not raised during that time. Yes. In this facsimile apparatus, when there is an incoming call, it is determined whether or not this is based on a specific service. If it is determined that the incoming call is based on a specific service, the call bell is started before the automatic reception of the facsimile is started. A process is performed in which the number of times of is larger than the set number.

JP-A-4-22262

  By the way, in a partner apparatus (facsimile apparatus) which is a transmission side of facsimile communication, a transmission timeout time is set with respect to a time during which a caller side identification signal such as a CNG signal is repeatedly transmitted. The facsimile machine on the receiving side automatically receives an incoming call when it detects a paging signal transmitted over a communication line a predetermined number of times, in other words, when the paging bell rings for a predetermined number of times. It has a function that can be set to. When the set number of times is set to a large value, the transmission side facsimile apparatus has a timing corresponding to the transmission timeout time at the timing of the incoming call. In this case, the receiving facsimile apparatus cannot receive facsimile data from the counterpart apparatus. For example, when the receiving side facsimile apparatus is to receive telephone communication by voice in addition to facsimile data, the receiving side facsimile apparatus has a set number of times for the purpose of avoiding an immediate automatic incoming call. May be set to a large value. The telephone communication by voice includes a case where a telephone is connected to a facsimile machine, a telephone call is made by the connected telephone, or a so-called answering machine function is executed.

  An object of the present invention is to provide a facsimile apparatus that can preferably receive transmission of facsimile data.

  One aspect of the present invention made in view of the above-described conventional problems is that a call signal connected to a communication line and automatically transmitted when the call signal transmitted through the communication line is detected a predetermined number of times, A facsimile apparatus that receives facsimile data transmitted from a destination apparatus that is a transmission side of facsimile communication, a first storage section that stores the set number of times, a time measuring section that measures the passage of time, A communication unit that receives the destination information corresponding to the destination device, the command signal for facsimile transmission, and the facsimile data, transmitted via the communication line, and the destination information of the destination information in the communication unit A first communication control unit that controls reception, an automatic incoming call when a call signal is detected for the set number of times stored in the first storage unit, and a command signal and fax A second communication control unit that controls reception of data, partner information received by the communication unit, and a command transmitted via the communication line upon receipt of reception of partner information by the communication unit A second storage unit that associates and stores the incoming call setting information corresponding to the reception state of the first type command signal among the signals, and the second communication control unit is the destination information in the communication unit Is received in the second storage unit, and the incoming call setting information associated with the specific destination information is information on reception failure. And when the measurement time measured by the time measuring unit has not passed a predetermined time from the reception failure timing corresponding to the incoming call setting information associated with the specific destination information, the first storage unit Less than the set number of times stored Controls automatic call in number, controls the reception of the command signal and the facsimile data at the communication unit, a facsimile apparatus.

  According to this, when a partner apparatus that has transmitted facsimile data that has failed in reception transmits facsimile data before a predetermined time elapses from the timing of reception failure, the destination apparatus receives an incoming call less than the set number of times. Facsimile data transmitted from can be received. This is particularly effective when the counterpart apparatus fails to transmit the facsimile data and repeats the transmission of the facsimile data a predetermined number of times at regular intervals. Facsimile data can be received by suitably executing an incoming call with a set number of times and an incoming call with a number less than the set number of times. As is apparent from the above description, the reception state of the first type command signal includes, for example, a state where reception of the first type command signal has failed (reception failure). The reception failure includes a case where the first type command signal cannot be received at all. In addition, when it is assumed that the first type command signal must be received a predetermined number of times, the reception failure includes a case where the first type command signal cannot be received a predetermined number of times. It is.

  This facsimile apparatus can also be configured as follows. In the facsimile apparatus, when the measurement time measured by the time measuring unit has passed a predetermined time from the reception failure timing corresponding to the incoming call setting information associated with the destination information in the second storage unit A storage control unit that changes the incoming call setting information from information in the case of reception failure to information in case of successful reception, and the second communication control unit receives the destination information when the communication unit receives the destination information. When the incoming call setting information associated with the specific destination information that matches the received destination information is changed from the information in the case of reception failure to the information in the case of reception success by the storage control unit, It is also possible to control automatic reception of the set number of times stored in one storage unit and control reception of command signals and facsimile data in the communication unit. According to this, even if the destination device has transmitted facsimile data that has failed to be received, when the facsimile data is transmitted after a predetermined time has elapsed from the timing of the reception failure, the incoming call should be received a set number of times. Can do. Even when the destination device of specific destination information is received less than the set number of times, the user does not need to perform an operation on the facsimile device to receive the call at the set number of times. . Successful reception is a case where reception failure is not as described above.

  The first type command signal includes a DCS signal, and the second storage unit receives the communication destination line information received by the communication unit and an incoming call when the communication unit information is received by the communication unit. The incoming call setting information corresponding to the reception state of the DCS signal transmitted via the network may be stored in association with each other. According to this, according to the reception state of the DCS signal, it is possible to execute an incoming call with a set number of times and an incoming call with a number less than the set number of times.

  The first type command signal includes a CNG signal, and the second storage unit receives the communication destination line information received by the communication unit and an incoming call when the communication unit information is received by the communication unit. The incoming call setting information corresponding to the reception state of the CNG signal transmitted via the network may be stored in association with each other. According to this, according to the reception state of the CNG signal, it is possible to execute an incoming call with a set number of times and an incoming call with a number less than the set number of times.

  Further, the first type command signal includes a CNG signal and a DCS signal, and the second storage unit is transmitted via the communication line when an incoming call is received when the destination information is received by the communication unit. When receiving CNG signal fails, it corresponds to the destination information received by the communication unit and the reception state of the CNG signal transmitted via the communication line when the destination information is received by the communication unit. The incoming call setting information to be stored in association with each other, and when the communication unit successfully receives the CNG signal transmitted via the communication line when the destination information is received by the communication unit, The other party information and the incoming call setting information corresponding to the reception state of the DCS signal transmitted via the communication line at the incoming call when the other party information is received by the communication unit may be stored in association with each other. Good. According to this, according to the reception state of the CNG signal and the DCS signal, it is possible to execute an incoming call with a set number of times and an incoming call with a number less than the set number of times. When reception of the CNG signal fails, the incoming call setting information corresponding to the reception state of the CNG signal is information in the case of reception failure.

  Regarding the DCS signal and the CNG signal in the above, the ITU-T TT. 30 transmission procedures and facsimile communication operation procedures relating to network control.

  In addition, the facsimile apparatus is operated by a user to notify a predetermined command to the facsimile apparatus, a notification unit for notifying the predetermined information, a notification control unit for controlling the predetermined information to be notified from the notification unit, and And an update unit for updating the set number of times stored in the first storage unit, and the second storage unit includes associated destination information and incoming call setting information. A plurality of sets are stored, and the notification control unit stores the incoming call setting information corresponding to the information in the case of reception failure in the second storage unit in association with the destination information, which is larger than the reference number serving as a reference. If so, the information related to the update of the set number of times is controlled to be notified from the notification unit, and the update unit reports information related to the update of the set number of times from the notification unit by the notification control unit. Accordingly, when a new set number of times is input through the operation unit, the set number of times stored in the first storage unit is updated to the input new set number of times. Good. According to this, when the reception of the facsimile data often fails regardless of the counterpart device, the set number of times can be updated. It is possible to reduce reception failures by updating the set number of times.

  According to the present invention, it is possible to obtain a facsimile apparatus that can preferably receive transmission of facsimile data.

  Embodiments for carrying out the present invention will be described with reference to the drawings. The present invention is not limited to the configurations described below, and various configurations can be employed in the same technical idea. For example, some of the configurations shown below may be omitted or replaced with other configurations. Moreover, you may make it include another structure.

<Facsimile machine>
A facsimile apparatus (hereinafter referred to as “FAX apparatus”) 10 will be described with reference to FIG. The FAX apparatus 10 is connected to a communication line for performing facsimile communication (hereinafter referred to as “FAX communication”). An example of the communication line is a public switched telephone network (PSTN) (hereinafter referred to as “PSTN”) 90. In addition, a next generation network (NGN (Next Generation Network)) capable of high-speed communication has been put into practical use. In the present embodiment, a PSTN 90 will be described as an example of a communication line. The FAX apparatus 10 is connected to the PSTN 90 and performs FAX communication with a FAX apparatus (hereinafter referred to as “partner apparatus”) 50. For example, facsimile data (hereinafter referred to as “FAX data”) transmitted from the partner apparatus 50 is received, and an image corresponding to the received FAX data is printed on a recording sheet.

  When receiving the FAX data, the FAX apparatus 10 can receive destination information corresponding to the destination apparatus 50 and can automatically receive an incoming call from the destination apparatus 50. As the destination information, a caller number (FAX number) of the destination device 50 is exemplified. In the present embodiment, a caller number will be described as an example of destination information. When the incoming call is an automatic incoming call, the user makes a setting for the automatic incoming call to the FAX apparatus 10 in advance. Specifically, the user sets the number of detections of the paging signal transmitted from the exchange 80 connected to the PSTN 90. In the FAX apparatus 10, when a call signal is detected a set number of times (hereinafter referred to as “set number”), the line is closed to the PSTN 90. In the FAX apparatus 10, a ringing sound is generated for the set number of times in response to the calling signal. This paging signal is a signal in which the ON (high level) period is 1 second, the OFF (low level) period is 2 seconds, and the frequency of the signal transmitted from the switch 80 during the ON period is 16 Hz. This calling signal is called a CI signal. Hereinafter, this calling signal is referred to as a “CI signal”. The CI signal is different from the call signal for the caller number described later. The calling signal for the caller ID is a signal whose ON and OFF periods are both 0.5 seconds and the frequency of the signal transmitted from the exchange 80 during the ON period (six times) is 16 Hz.

  As shown in FIG. 1, the FAX apparatus 10 includes a CPU 12, a program ROM 14, a RAM 16, a flash ROM 18, a reading unit 20, a printing unit 22, a display unit 24, an operation unit 26, and a time measuring unit 28. The communication unit 30 is provided. These units 12 to 30 are connected to a bus line 32. The counterpart apparatus 50 may be a conventional FAX apparatus, or may be the same apparatus as the FAX apparatus 10.

  The CPU 12 executes arithmetic processing. The program ROM 14 stores, for example, computer programs for various processes as will be described later. The RAM 16 serves as a storage area used when the CPU 12 executes various computer programs. In the RAM 16, an area for information (data) used in processing to be described later is secured, and information (data) is stored (managed). The CPU 12 controls the FAX apparatus 10 by executing various computer programs stored in the program ROM 14, for example. As a result, the FAX apparatus 10 executes various processes and implements various functions. The flash ROM 18 can store various data. For example, the flash ROM 18 stores a set number of times for automatic incoming calls and an incoming call management table.

  As shown in FIG. 2, the incoming call management table is a table in which a caller number, incoming call setting information, and a release timer are stored in association with each other. In the caller number, the caller number of the destination apparatus 50 received as described later is stored. When the caller ID is not notified, the caller ID is “not notified”. The incoming call setting information corresponds to the reception state of the CNG signal or the DCS signal received in the incoming call in which the caller number is received. The CNG signal is a command signal (calling side identification signal) for notifying that the transmission is facsimile transmission (hereinafter referred to as “FAX transmission”). The DCS signal is a command signal (digital command signal) for the counterpart device 50 to notify a function such as an encoding method used for the current FAX transmission. The incoming call setting information is turned OFF when the CNG signal and the DCS signal can be received (when reception is successful). The incoming call setting information is turned ON when the CNG signal cannot be received (when reception fails), or when the DCS signal cannot be received when the CNG signal can be received. In the FAX apparatus 10, when a CNG signal is received a predetermined number of times (hereinafter referred to as “CNG reception count”) after automatically receiving a call, a CED signal and a DIS signal are transmitted to the counterpart apparatus 50. The Transmission of the CED signal may be omitted. Therefore, when the CNG signal is received a predetermined number of times, it is assumed that the CNG signal has been received. As will be described in detail later, the FAX apparatus 10 is controlled so as to automatically receive a call when the reception is unsuccessful, a number less than the set number. The cancellation timer cancels such control and sets the timing for automatic incoming call according to the set number of times. Specifically, the release timer stores a release time as a timing for shifting to automatic incoming call according to the set number of times. When the release timer is not set, the release timer is set to “none” (unregistered).

  The reading unit 20 reads a document set on the FAX apparatus 10. When FAX data is received, the printing unit 22 prints an image corresponding to the received FAX data on a recording sheet. The display unit 24 is a display for displaying various information. The operation unit 26 includes a plurality of keys. The user can input various commands to the FAX apparatus 10 by operating the operation unit 26. The time measuring unit 28 has a clock function and measures the passage of time.

  The communication unit 30 is connected to the PSTN 90 and transmits / receives various information, command signals, and FAX data. Specifically, the communication unit 30 includes an NCU (Network Control Unit) or a semiconductor DAA and a modem. The communication unit 30 has a function of switching between line closing and line opening with the PSTN 90. The communication unit 30 demodulates and receives FAX data transmitted to the FAX apparatus 10 from analog to digital, and transmits FAX data by modulating the FAX data to be transmitted from digital to analog. When a next generation network is used as a communication line, the FAX apparatus 10 includes a network interface connected to the next generation network.

<Outline of automatic incoming calls by set number of times>
An outline of automatic incoming calls based on the set number of times will be described with reference to FIG. Although details will be described later, in the FAX apparatus 10, the caller ID reception operation of the counterpart apparatus 50 is performed prior to the detection of the CI signal shown in FIG. However, in FIG. 3, illustration regarding this is omitted.

  The counterpart apparatus 50 reads the set original, generates FAX data obtained by encoding image data corresponding to the read original, and makes a call with the FAX apparatus 10 as the destination. Along with this, as shown in FIG. 3, the CNG signal is transmitted from the partner apparatus 50 to the exchange 80, and the CI signal is transmitted from the exchange 80 to the FAX apparatus 10. In the FAX apparatus 10, when the CI signal transmitted from the exchange 80 is detected N times for the set number of times, the line is automatically closed. As described above, when the CNG signal is received twice (refer to “CNG 1” and “CNG 2” in FIG. 3) based on FIG. , CED signal and DIS signal or DIS signal are transmitted. The number of CNG receptions may be, for example, less than 2 cycles. The CNG signal is a command signal with an ON period of 0.5 seconds and an OFF period of 3 seconds. Therefore, the number of CNG reception times is less than two cycles means that, for example, after a CNG signal having an ON period of 0.5 seconds and an OFF period of 3 seconds (one cycle) is detected once, This is a case where the ON period is detected again. In other words, this is a case where the ON period of the CNG signal is detected twice. If one cycle of ON and OFF is set to one time, the second cycle is only ON, so the number of times can be 1.5.

  The CED signal and the DIS signal or the DIS signal transmitted from the FAX apparatus 10 are received by the counterpart apparatus 50. The counterpart apparatus 50 transmits a DCS signal to the FAX apparatus 10 in response to the reception of the DIS signal, and the FAX apparatus 10 receives this. Although not shown in FIG. 3, transmission / reception of FAX data is performed between the partner apparatus 50 and the FAX apparatus 10 thereafter.

<Main processing>
The main process executed by the FAX apparatus 10 will be described with reference to FIG. The main process is started when the power of the FAX apparatus 10 is turned on. The CPU 12 that has started the main process determines whether there is an incoming call (S100). When the CPU 12 detects the CI signal transmitted from the exchange 80 via the PSTN 90, the CPU 12 determines that an incoming call has been received.

  By the way, when the other party device 50 makes a call without setting its own caller number not to be notified, the FAX device 10 receives the caller number of the other party device 50 prior to the detection of the CI signal. . The caller ID is received by the same method as before, but the outline thereof will be briefly described. The caller number is also transmitted from the switch 80 after the call signal for the caller number transmitted from the switch 80 is transmitted six times. The CPU 12 controls the communication unit 30 at a timing within a predetermined period after the call signal for the caller ID is detected six times. The communication unit 30 receives a caller number transmitted via the PSTN 90. The CPU 12 acquires the caller number received by the communication unit 30. In Japan, after the call signal for the caller number is transmitted six times, the communication unit 30 closes the line to the PSTN 90, and after the caller number is received, the line is opened. . The CI signal is detected after the caller ID is received. When the other party device 50 is set to non notification, the caller number is not transmitted, and the communication unit 30 does not receive the caller number. Therefore, the CPU 12 cannot acquire the caller number.

  When there is an incoming call (S100: Yes), the CPU 12 executes a reception process (S102). The reception process will be described later. After executing the reception process, the CPU 12 returns the process to S100 and executes it. If there is no incoming call (S100: No), the CPU 12 determines whether the release timer associated with any caller number stored in the incoming call management table has expired (S104). In S104, the CPU 12 accesses the incoming call management table and sets one record stored in the incoming call management table as a target record in S104. For example, the CPU 12 sets the records stored in the incoming call management table as target records in order from the top. The CPU 12 compares the current time measured by the timer unit 28 with the time of the release timer associated with the caller number in the target record. When the current time has not passed the time of the release timer, the CPU 12 determines that the release timer of the target record has not timed up (S104: No). In this case, the CPU 12 shifts the process to S110.

  When the current time has passed the time of the release timer, the CPU 12 determines that the release timer of the target record is up (S104: Yes), and sets “OFF” in the incoming setting information of the target record. Set (S106). Subsequently, the CPU 12 sets “none” in the release timer for the target record (S108). After executing S108, it is determined whether or not the processing of S104 to S108 has been completed for all the records stored in the incoming call management table (S110). If there is an unprocessed record and processing has not been completed for all records (S110: No), the CPU 12 returns the processing to S104. Thereafter, the CPU 12 executes the processes of S104 to S108 described above using one of the unprocessed records as a target record. When there is no unprocessed record and the process is completed for all the records (S110: Yes), the CPU 12 returns the process to S100. The CPU 12 repeatedly executes the main process until the power of the FAX apparatus 10 is turned off.

  S104 to S110 will be specifically described with reference to FIG. In this description, it is assumed that the current time measured by the time measuring unit 28 is 12:15. When S104 is executed for the first time after the determination of S100 is negative (S100: No), the CPU 12 records (caller number “123-456” stored at the top of the incoming call management table shown in FIG. -7890 ") as a target record, the release timer" 12:10 "included in this record is compared with the current time" 12:15 ". In this case, since the current time “12:15” is the time when the cancellation timer “12:10” has already elapsed, the CPU 12 affirms S104 (S104: Yes). Subsequently, the CPU 12 sets the incoming call setting information “ON” associated with the caller number “123-456-7890” in the target record to “OFF” (S106), and the release timer “12:10”. Is set to “none” (S108). As a result, in the target record of the incoming call management table, the incoming call setting information and the release timer associated with the caller number “123-456-7890” are “OFF” and “none”, respectively.

  Next, the CPU 12 executes S110. When the current target record is a record of the caller number “123-456-7890”, there are three unprocessed records (see FIG. 2). Therefore, the CPU 12 denies S110 (S110: No), sets the record of the caller number “234-567-8901” as the target record, and sets the release timer “12:20” included in this record to the current time. Compare with "12:15". In this case, since the current time “12:15” is the time before the cancellation timer “12:10” elapses, the CPU 12 denies S104 (S104: No), and the process proceeds to S110. . The CPU 12 executes the processes of S104 to S110 for each of the remaining two records. When the record of the caller ID “non-notification” is set as a target record and the determination in S104 is negative (S104: No) and the process proceeds to S110, the CPU 12 stores all the records stored in the incoming call management table. S110 is affirmed (S110: Yes) and the process returns to S100, assuming that the process for the record is completed.

<Reception processing>
The reception process executed in S102 of the main process in FIG. 4 will be described with reference to FIGS. CPU12 which started the reception process judges whether the caller number is received by the communication part 30 (S200). As described above, the caller number is received by the communication unit 30 before the CI signal is detected. When the caller number is received (S200: Yes), the CPU 12 sets the acquired caller number as the current caller number (S202). When the caller number is not received (S200: No), the CPU 12 sets non-notification as the current caller number (S204).

  After executing S202 or S204, the CPU 12 accesses the incoming call management table and determines whether the incoming call setting information associated with the caller number set as the current caller number is “ON” (S206). ). For example, it is assumed that the caller number set as the caller number this time is “not notified”. In the incoming call management table shown in FIG. 2, the incoming call setting information associated with the caller ID “not notified” is “OFF”. In such a case, CPU12 denies S206 (S206: No) and transfers a process to S208. If the current caller number is not stored in the incoming call management table, the incoming call setting information is handled as “OFF”. Therefore, the CPU 12 moves the process to S208. It is assumed that the caller number set as the current caller number is “123-456-7890”. In the incoming call management table shown in FIG. 2, the incoming call setting information associated with the caller number “123-456-7890” is “ON”. In such a case, CPU12 affirms S206 (S206: Yes) and transfers a process to S210. Although details will be described later, when setting “ON” in the incoming call setting information, the CPU 12 also sets a release time in the release timer (see S312 and S314 in FIG. 6). In addition, when there is no incoming call (see S100: No in FIG. 4), the CPU 12 sets “OFF” in the incoming call setting information and sets the release timer to “none” for the record whose release timer has timed out. (See S106 and S108 in FIG. 4). Therefore, if the incoming call setting information is “ON” (S206: Yes) and the process proceeds to S210, the release timer has not expired.

  In S <b> 208, the CPU 12 controls automatic incoming calls based on the set number of times stored in the flash ROM 18. That is, when the CI signal is detected for the set number of times, the CPU 12 outputs a command for closing the line to the communication unit 30 to control the communication unit 30. As a result, the communication unit 30 closes the line to the PSTN 90. In S <b> 210, the CPU 12 controls automatic incoming calls by a number less than the set number stored in the flash ROM 18 (hereinafter referred to as “exception number of incoming calls”). That is, the CPU 12 outputs a command for closing the line to the communication unit 30 and controls the communication unit 30 when the CI signal is detected by the number of exceptional incoming calls. The number of exceptional incoming calls is, for example, once. As a result, the communication unit 30 closes the line to the PSTN 90.

  After executing S208 or S210, the CPU 12 determines whether a CNG signal is received by the communication unit 30 (S212). When the CNG signal is not received (S212: No), the CPU 12 controls normal communication processing (S214). The normal communication process is, for example, a process in a so-called home mode. Specifically, the CPU 12 outputs a message that states that “if FAX transmission is to be performed, the start button of the partner device 50 is pressed, and if it is a telephone, the device waits as it is”. The user of the destination device 50 who has heard this message performs an action according to the message. When the user presses the start key to start FAX transmission, the FAX apparatus 10 receives a CNG signal at this timing, and then receives FAX data. The CPU 12 controls the printing unit 22 when FAX data is received. The printing unit 22 prints an image corresponding to the received FAX data on a recording sheet. When the user of the counterpart device 50 does not press the start key, the CPU 12 executes processing such as ringing a ringing tone. When the user of the FAX apparatus 10 responds, the telephone communication process by voice is executed by controlling the communication unit 30 or the like. When the FAX apparatus 10 has an answering machine function and is set to the answering machine mode, the CPU 12 executes a process for the answering machine function as a normal communication process. The home mode and the answering machine mode are also realized in a conventional FAX apparatus. Therefore, the other description regarding this is abbreviate | omitted. After executing S214, the CPU 12 proceeds to S304 in FIG.

  When the CNG signal is received (S212: Yes), the CPU 12 determines the number of times of reception of the received CNG signal (S216). When the number of receptions is less than the number of CNG receptions (S216: less than the number of CNG receptions), the CPU 12 proceeds to S310 in FIG. When the number of receptions is the number of CNG receptions (S214: CNG reception number / refer to “CNG 1” and “CNG signal 2” in FIG. 3), the CPU 12 controls the communication unit 30 so that the CED signal and the DIS signal are Sequentially transmit (see S218 / "CED" and "DIS" in FIG. 3). The CED signal and the DIS signal are received by the counterpart device 50, respectively. After executing S218, the CPU 12 shifts the processing to S300 of FIG. As described above, transmission of the CED signal may be omitted in S218. The DIS signal is a command signal including reception capability information regarding decoding capability corresponding to an image data encoding method.

  In S300 of FIG. 6, the CPU 12 determines whether the DCS signal is received by the communication unit 30. When the DCS signal is not received (S300: No), the CPU 12 shifts the process to S310. When the DCS signal is received (S300: Yes / refer to “DCS” in FIG. 3), the CPU 12 controls the communication unit 30 and receives FAX data (S302). The CPU 12 controls the printing unit 22. The printing unit 22 prints an image corresponding to the received FAX data on a recording sheet. The CPU 12 accesses the incoming call management table and sets “OFF” in the incoming call setting information associated with the caller number set as the current caller number (S304). Subsequently, the CPU 12 sets “none” in the release timer associated with the caller number set as the current caller number (S306). Here, when the caller number set as the current caller number is not stored in the incoming call management table, the CPU 12 adds a new record, and is set as the current caller number in the added record. The caller number, the incoming call setting information “OFF”, and the release timer “none” may be additionally stored in association with each other. Thereafter, the CPU 12 controls the communication unit 30, executes a predetermined procedure according to the FAX communication standard, and terminates the current incoming call (S308). At the end of the incoming call, the communication unit 30 opens the line from the PSTN 90.

  In S310, the CPU 12 cannot receive the CNG signal by the number of CNG receptions (see S216 in FIG. 5: less than the number of CNG receptions), or has not received the DCS signal, Judge that it failed. The CPU 12 accesses the incoming call management table and sets “ON” in the incoming call setting information associated with the caller number set as the current caller number (S312). Subsequently, the CPU 12 sets the release time in the release timer associated with the caller number set as the current caller number (S314). The set release time is set to a time after a lapse of a fixed time from the current time measured by the timer unit 28. For example, in the partner apparatus 50 that failed in FAX transmission, the failed FAX transmission is repeatedly executed at predetermined intervals. The fixed time for the release time is determined in advance in consideration of the interval at which retransmission is repeated. For example, the fixed time is 10 minutes, and the release time is 10 minutes after the current time. Here, when the caller number set as the current caller number is not stored in the incoming call management table, the CPU 12 adds a new record, and is set as the current caller number in the added record. The caller number, the incoming call setting information “ON”, and the release time as the release timer are additionally stored in association with each other.

  After executing S314, the CPU 12 accesses the incoming call management table and determines whether the number of incoming call setting information “ON” stored in the incoming call management table is equal to or greater than the reference number (S316). The reference number is determined in advance and stored in the flash ROM 18, for example. The reference number may be changed by the user by operating the operation unit 26. The determination condition in S316 may be whether the number of incoming setting information “ON” is greater than the reference number. When specifying the number of incoming call setting information “ON” stored in the incoming call management table, the CPU 12 sequentially counts the number of incoming call setting information “ON” for each record stored in the incoming call management table. . At this time, a counter area for counting is secured on the RAM 16. For example, taking the incoming call management table shown in FIG. 2 as an example, the number of incoming call setting information “ON” is “2” (refer to each record in the upper two levels), and is therefore managed in the counter area on the RAM 16. The value is “2”. When the number of the incoming setting information “ON” managed in the counter area on the RAM 16 is less than the reference number and not more than the reference number (S316: No), the CPU 12 shifts the process to S308, and the same as above. Then, this incoming call is terminated. When the number is equal to or greater than the reference number (S316: Yes), the CPU 12 displays a call count input screen as shown in FIG. 7, for example, on the display unit 24 (S318). As shown in FIG. 7, the call count input screen includes an input box 241 together with a message regarding reception failure and update of the call count, and the current call count, as information regarding the update of the set count. As for the number of calls on the call count input screen, as described above, the FAX apparatus 10 responds to the call signal, and the ringing tone sounds for the set number of times, so the number of calls corresponds to the set number of times. The number-of-calls input screen can also be referred to as a set number-of-times input screen when the FAX apparatus 10 is used as a reference. However, the content that the user recognizes by updating in accordance with the input on the call count input screen is a change in the number of times that the ringing sound (call count) is generated. Therefore, on the call count input screen, the set count is expressed as the call count. When updating the number of calls according to the display of the number-of-calls input screen, for example, the user operates a numeric keypad included in the operation unit 26 and inputs a new number of calls. The input new number of calls is displayed in the input box 241. For example, when the input number of calls is confirmed, the user presses a confirmation button included in the operation unit 26, and when the number of calls is not updated, the user presses a cancel button included in the operation unit 26.

  Subsequently, the CPU 12 determines whether a new number of calls has been input according to the display of the number-of-calls input screen (S320). As described above, when a new number of calls is input and the OK button of the operation unit 26 is pressed, S320 is affirmed (S320: Yes). In this case, the CPU 12 acquires the input new number of calls as a new set number, and updates the set number stored in the flash ROM 18 to the new set number (S322). When the cancel button of the operation unit 26 is pressed, or when nothing is input and a predetermined period has elapsed, S320 is denied (S320: No). When S320 is denied (S320: No) or after executing S322, the CPU 12 shifts the process to S308, and ends the current incoming call in the same manner as described above.

<Effects of this embodiment>
According to this embodiment, the following effects can be obtained.

  (1) In the above, when the FAX data reception fails due to an incoming call with the set number of times (see S310 in FIG. 6), “ON” is set in the incoming call setting information associated with the caller number set as the current caller number. Is set (see S312 in FIG. 6). Therefore, after the failure, in the FAX transmission repeated by the partner apparatus 50 related to the failure, the automatic incoming call is executed with the number of exceptional incoming calls that is less than the set number of times, and the FAX data can be received (FIG. 6 S302). In the FAX apparatus 10, it is possible to prevent the occurrence of a situation in which the reception of FAX data transmitted from the same counterpart apparatus 50 is repeated and the FAX data cannot be received. An incoming call with the exceptional number of incoming calls is executed for a caller number whose incoming call setting information is “ON” (see S206: Yes in FIG. 5). For this reason, an incoming call from the destination device 50 having a caller ID whose incoming call setting information is “OFF” can be an incoming call with a set number of times.

  This point will be described based on specific examples. The counterpart device 50 sets a transmission timeout time in the range of up to 60 seconds, for example, regarding the time for continuously transmitting the CNG signal. It is assumed that the destination device 50 has a transmission timeout time of 50 seconds. When the transmission of FAX data fails, the partner apparatus 50 retransmits the FAX data that failed to be transmitted after 5 minutes to the sender number of the failed transmission. In the FAX apparatus 10, it is assumed that the set number of times is stored in the flash ROM 18 as 15 times, the fixed time for the release timer is 10 minutes, and the number of exceptional incoming calls is 1. The FAX apparatus 10 transmits a CED signal and a DIS signal to the counterpart apparatus 50 when the CNG signal is detected twice after the incoming call.

  As described above, since the CI signal is a signal having an ON period of 1 second and an OFF period of 2 seconds, 45 seconds (3 seconds × 15 times) are required to detect the CI signal 15 times. is there. As described above, the CNG signal is a signal having an ON period of 0.5 seconds and an OFF period of 3 seconds. Therefore, in order to receive two CNG signals, 7 seconds (3.5 seconds × 2) required. Therefore, in order for the FAX apparatus 10 to complete the reception of the second CNG signal, it takes about 52 seconds in total from the timing of the incoming call (see S100: Yes in FIG. 4). In such a case, the FAX apparatus 10 cannot receive two CNG signals (see “CNG 1” and “CNG 2” in FIG. 3) within the transmission timeout period (S212 in FIG. 5: No, Or, refer to S216: less than CNG reception count). As a result, the FAX apparatus 10 does not transmit the CED signal and the DIS signal (see S218 in FIG. 6), and the counterpart apparatus 50 receives these signals before the transmission timeout period (50 seconds) elapses. I can't. For this reason, the partner apparatus 50 cannot move to the next procedure of transmitting a DCS signal (see “DCS” in FIG. 3), and the FAX apparatus 10 fails to receive FAX data (in FIG. 6). (See S310). Although the FAX apparatus 10 has received two CNG signals (see S216 in FIG. 5: CNG reception count), the timing for transmitting the CED signal and the DIS signal (see S218 in FIG. 5) is, for example, a transmission timeout time. In the case of a near-end, the FAX apparatus 10 cannot receive the DCS signal (S300 in FIG. 6: No), and fails to receive FAX data as in the case of the CNG signal (see S310 in FIG. 6). ).

  In such a state, the incoming call setting information is set to “ON” in association with the caller number of the destination apparatus 50 that has transmitted the FAX data that has failed to be received (see S312 in FIG. 6). Therefore, at the time of retransmission after 5 minutes, an incoming call is received when the CI signal is detected once (S210 in FIG. 5), and the subsequent processing can be suitably executed (S212 in FIG. 5: Yes, S216: CNG signal reception count, S218, see S302 in FIG. 6).

  (2) In the above, when an automatic incoming call according to the number of exceptional incoming calls is executed (see S210 in FIG. 5) and FAX data can be received (see S302 in FIG. 6), this is set as the current caller number “OFF” is set in the incoming call setting information associated with the caller number, and “None” is set in the release timer (see S304 and S306 in FIG. 6). Therefore, it is not necessary for the user to perform a predetermined operation in order to make a call with the set number of times after successfully receiving the FAX data of the caller ID from the destination device 50. It is possible to prevent an incoming call with the number of exceptional incoming calls.

  (3) In the above, the reception of FAX data repeatedly fails, and the incoming call setting information becomes “ON” in many incoming caller numbers in the incoming call management table (S316: Yes in FIG. 6). (Refer to FIG. 6) (refer to S318 to S322 in FIG. 6). Therefore, it is possible to reduce the number of reception failures due to the set number of times.

  This point will be described based on specific examples. The premise in the description is the same as in the case of “(1)” described above. However, the set number of times is updated from 15 times to 10 times. Since the CI signal is a signal having the cycle as described above, it takes 30 seconds (3 seconds × 10 times) to detect the CI signal 10 times as the set number of times. It takes 7 seconds (3.5 seconds × 2 times) to receive two CNG signals. Therefore, it takes about 37 seconds in total from the timing of the incoming call (see S100: Yes in FIG. 4) to complete the reception of the second CNG signal in the FAX apparatus 10. In such a case, the FAX apparatus 10 can receive two CNG signals (see “CNG 1” and “CNG 2” in FIG. 3) within the transmission timeout period (S216: CNG reception in FIG. 5). See times). The counterpart apparatus 50 receives the CED signal and the DIS signal from the FAX apparatus 10 before the transmission timeout time elapses, and proceeds to the next procedure (see “DCS” in FIG. 3) of transmitting the DCS signal. be able to. As a result, the FAX apparatus 10 receives the DCS signal (S300 in FIG. 6: Yes) and can receive the FAX data (see S302 in FIG. 6). That is, if the set number of times is updated from 15 times to 10 times, the FAX apparatus 10 can receive FAX data in the first FAX transmission from the partner apparatus 50.

<Modification>
This embodiment can also be performed as follows. Even with such a configuration, the same effect as described above can be obtained.

  (1) In the above description, the caller number of the partner device 50 has been described as an example of the partner information. In addition, when the sender name of the counterpart device 50 is transmitted via the PSTN 90 and can be received, the sender name may be adopted as the counterpart information. In this case, in the incoming call management table (see FIG. 2) described based on the caller number, the caller name is associated with the incoming call setting information and the release timer. In the main process (see FIG. 4) and the reception process (see FIGS. 5 and 6), each process is executed according to the caller name in the same manner as in the case of the caller number described above. When the caller number and the caller name of the partner apparatus 50 can be received, the caller management table (see FIG. 2), the caller number and / or caller name are associated with the incoming call setting information and the release timer. In the main process (refer to FIG. 4) and the reception process (refer to FIG. 5 and FIG. 6), each process is executed according to the caller number and / or the caller name as in the case of the caller number described above.

  (2) In the above description, the case where the incoming call management table is stored in the flash ROM 18 has been described as an example. The incoming call management table may be a dedicated table for each process in FIGS. 4 to 7, but the FAX apparatus 10 stores a so-called communication management table that manages the transmission / reception history of FAX data, as in the conventional FAX apparatus. If so, incoming call setting information and a cancellation timer may be added to the communication management table as management items, and these may be associated with a caller number stored in the communication management table. Such a FAX apparatus 10 accesses the communication management table at the timing of accessing the incoming call management table (for example, see S104 to S110 in FIG. 4, S206 in FIG. 5, S304, S306, S312 and S314 in FIG. 6). The same processing as described above is executed.
