The RAM 56 stores predetermined data (information) used in the process during the execution of various processes. The CPU 52 controls the mobile terminal device 50 by executing various computer programs stored in the ROM 54. Thereby, in the mobile terminal device 50, various processes are executed, and various functions are realized.

<Communication device processing>
Communication device processing executed by the communication device 20 will be described with reference to FIGS. 4 and 5. The communication device process is started when, for example, the communication device 20 is powered on. The CPU 22 that has started the communication device process determines whether or not an NFC connection request has been acquired (S100). The connection request is transmitted from the mobile terminal device 50 and received by the short-range communication unit 38 when NFC is established between the communication device 20 and the mobile terminal device 50 (see S200 in FIG. 6). The CPU 22 acquires a connection request via the short-range communication unit 38. When the connection request has not been acquired (S100: No), the CPU 22 repeatedly executes S100 until the connection request is acquired. When the connection request is acquired (S100: Yes), the CPU 22 performs pairing in NFC and establishes NFC with the requesting mobile terminal device 50.

  The CPU 22 acquires the terminal ID of the portable terminal device 50 and the partner information of the partner device 80 that is the destination of facsimile transmission (S102). The terminal ID and destination information are transmitted from the portable terminal device 50 by NFC (see S202 in FIG. 6) and received by the short-range communication unit 38. The CPU 22 acquires a terminal ID and counterpart information via the short-range communication unit 38. The CPU 22 associates the acquired terminal ID with the counterpart information and writes it in the transmission history memory (S104). In the transmission history memory, the acquired terminal ID and destination information are stored in association with a predetermined communication number (for example, the smallest number at the timing of writing). Specifically, if no information is stored in the transmission history memory, the terminal ID acquired in S102 is “ID1”, and the destination information is “052-11-2122”, the CPU 22 , “ID1” and “052-11-2222” are written in the transmission history memory in association with the communication number “1” (see FIG. 2A).

  Next, the CPU 22 acquires transmission data (S106). The transmission data is transmitted by wireless LAN communication from the mobile terminal device 50 with NFC established (see S206 in FIG. 6) and received by the wireless LAN communication unit 40. The wireless communication system change from NFC to wireless LAN communication is performed according to the Wi-Fi handover described above. The CPU 22 acquires transmission data via the wireless LAN communication unit 40. The CPU 22 stores the acquired transmission data in the transmission data memory (S108). As a result, the transmission data is stored in a predetermined address of the transmission data memory. The CPU 22 writes the address indicating the storage location of the transmission data in the transmission history memory in association with the communication number corresponding to the writing in S104 (hereinafter referred to as “processing target communication number”). Thus, the transmission history memory is in a state in which the communication number, the terminal ID, the destination information, and the transmission data storage location are stored in association with each other. For example, it is assumed that the communication number to be processed is “1” (see FIG. 2A) and the transmission data acquired in S106 is “data for communication No. 1”. In S108, the CPU 22 saves “communication No. 1 data” in “address 1” of the transmission data memory (see FIG. 3B). Then, the CPU 22 writes the transmission data storage location “address 1” in the transmission history memory in association with the communication number “1” to be processed (see FIG. 2B).

  The CPU 22 starts control of facsimile transmission for the destination information acquired in S102 and stored in S104 and the transmission data stored in the transmission data memory in S108 (S110). By this control, facsimile transmission of transmission data from the line communication unit 36 to the partner apparatus 80 corresponding to the partner information is started. The transmission data is encoded in a format according to a communication standard for facsimile transmission. The CPU 22 determines whether or not the facsimile transmission started in S110 is successful (S112). It is assumed that the communication device 20 has a redial function. The redial function corresponds to a case where the counterpart device 80 is communicating with a communication device other than the communication device 20, and repeats facsimile transmission to the counterpart device 80 at a predetermined interval and a predetermined number of times. The function to execute. Since the redial function is a function that also includes a known communication device that includes a facsimile function, other description related thereto is omitted. In the communication device 20 having the redial function, if the transmission data can be transmitted by facsimile to the destination device 80 at any timing, it is determined that the facsimile transmission is successful (S112: Yes). On the other hand, if the transmission data cannot be transmitted to the destination device 80 by facsimile even after being repeated a predetermined number of times, it is determined that the facsimile transmission has failed (S112: No).

  When the facsimile transmission is successful (S112: Yes), the CPU 22 writes the transmission result “OK” in the transmission history memory in association with the communication number to be processed (S114). Thus, the transmission history memory is in a state in which the communication number, terminal ID, destination information, transmission data storage location, and transmission result are stored in association with each other (see FIG. 2C). Subsequently, the CPU 22 writes the terminal ID, destination information, and transmission result stored in the transmission history memory in association with the communication number to be processed in the communication management memory (S116). For example, if no information is stored in the communication management memory and the transmission history memory is in the state of FIG. 2C, the CPU 22 associates the communication number “1” with “ID1”. “052-11-2222” and “OK” are written in the communication management memory (see FIG. 3A). If one or more records are stored in the communication management memory, the communication number is the number next to the communication number of the last record (for example, if the communication management memory is in the state shown in FIG. “2” next to the number “1”).

  Next, the CPU 22 deletes the transmission data stored in this storage location from the transmission data memory according to the transmission data storage location associated with the communication number to be processed in the transmission history memory (S118). Subsequently, the CPU 22 deletes each piece of information associated with the processing target communication number from the transmission history memory (S120). In S120, the CPU 22 also deletes the communication number to be processed from the transmission history memory. When there is one record stored in the transmission history memory (see FIGS. 2C and 2D), the transmission history memory is in a state where no information is stored (unregistered state). . After executing S120, the CPU 22 ends the communication device process.

  Returning to S112, if the facsimile transmission fails (S112: No), the CPU 22 shifts the process to S122 of FIG. 5, and determines whether or not the retransmission flag is “ON”. The retransmission flag is information indicating whether or not to repeatedly perform facsimile transmission according to each piece of information associated with the communication number to be processed stored in the transmission history memory, and the initial value is “OFF”. It is. The retransmission flag “ON” indicates re-execution. The retransmission flag is set in S142 of FIG. The CPU 22 performs control to display a communication error screen on the display unit 32 in the transition to S122. The communication error screen includes, for example, information “communication error, please send again”. By this control, a communication error screen is displayed on the display unit 32. The user to be operated can check the communication error screen displayed on the display unit 32. The user to be operated is a user who has performed an operation that causes S100 to be affirmed (S100: Yes), such as holding the mobile terminal device 50 over the communication device 20 (short-range communication unit 38).

  When the retransmission flag is “ON” (S122: Yes), the CPU 22 shifts the process to S126. When the retransmission flag is not “ON” (S122: No), the CPU 22 writes the transmission result “NG” in the transmission history memory in association with the communication number to be processed (S124). As a result, the transmission history memory is in a state in which the communication number, terminal ID, destination information, transmission data storage location, and transmission result are stored in association with each other (see FIG. 2D). After executing S124, the CPU 22 shifts the process to S126.

  In S126, the CPU 22 determines whether or not the storage time has elapsed since the facsimile transmission failed. The storage time is appropriately set in consideration of various conditions as the time for accepting retransmission of failed facsimile transmissions. The storage time is, for example, a predetermined time of several minutes. When the storage time has elapsed (S126: Yes), the CPU 22 performs control to transmit a transmission stop notification from the wireless LAN communication unit 40 to the mobile terminal device 50 (S128). With this control, a transmission stop notification is transmitted from the wireless LAN communication unit 40 to the mobile terminal device 50 via wireless LAN communication. The transmission stop notification is a notification indicating that the transmission of the transmission data based on the request from the portable terminal device 50 has failed, and thereafter, a retransmission instruction (to be described later) is not accepted and is canceled. Thereafter, the CPU 22 returns the process to S116 of FIG. 4 and executes the processes after S116. In this case, in S116, based on FIG. 2D, the transmission result written in the communication management memory is “NG”.

  When the storage time has not elapsed (S126: No), the CPU 22 determines whether or not an NFC connection request has been acquired (S130). The connection request is transmitted from the mobile terminal device 50 or a different mobile terminal device when the mobile terminal device including the mobile terminal device 50 of the user to be operated is held over the communication device 20 (from the mobile terminal device 50). Is received by the short-range communication unit 38) (see S212 in FIG. 7). The CPU 22 acquires a connection request via the short-range communication unit 38.

  When the connection request has not been acquired (S130: No), the CPU 22 returns the process to S126, and executes the processes after S126. When the connection request is acquired (S130: Yes), the CPU 22 performs pairing in NFC and establishes NFC with the requesting mobile terminal device 50 or a mobile terminal device different from this. The CPU 22 acquires the terminal ID of the requesting mobile terminal device 50 or a mobile terminal device different from the requesting mobile terminal device 50 (S132). The terminal ID is transmitted from the requesting portable terminal device 50 or a different portable terminal device (refer to S214 in FIG. 7 for the terminal ID from the portable terminal device 50) and received by the short-range communication unit 38. . The CPU 22 acquires a terminal ID via the short-range communication unit 38. The CPU 22 determines whether or not the terminal ID acquired in S132 matches the terminal ID associated with the communication number to be processed (S134).

  If the two terminal IDs do not match (S134: No), the CPU 22 writes the transmission result “ID mismatch” in the transmission history memory in association with the communication number to be processed (S136). As a result, the transmission history memory is in a state in which the communication number, terminal ID, destination information, transmission data storage location, and transmission result are stored in association with each other (see FIG. 2E). After executing S136, the CPU 22 returns the process to S116 of FIG. 4 and executes the processes after S116 regardless of the storage time (see S126). In this case, in S116, based on FIG. 2E, the transmission result written in the communication management memory is “ID mismatch”.

  If both terminal IDs match (S134: Yes), the CPU 22 performs control to transmit a resendable notification from the short-range communication unit 38 to the mobile terminal device 50 (S138). By this control, a resendable notification is transmitted from the short-range communication unit 38 to the portable terminal device 50 having the matching terminal ID via NFC. The resendable notification is a notification indicating that the failed facsimile transmission can be retransmitted. Although details will be described later, according to the transmission enable notification, the mobile terminal device 50 displays the “Resend” button of the operation unit 60 on the transmission operation screen displayed on the display unit 58 in a state where it can be pressed (S220 in FIG. 7). And FIG. 8B).

  Thereafter, the CPU 22 determines whether or not a retransmission instruction has been acquired (S140). The retransmission instruction is a command for instructing retransmission of facsimile transmission started in S110 of FIG. The retransmission instruction is transmitted from the mobile terminal device 50 by NFC in S228 of FIG. In the communication device 20, the retransmission instruction transmitted from the mobile terminal device 50 is received by the short-range communication unit 38. The CPU 22 acquires a retransmission instruction via the short-range communication unit 38.

  When the retransmission instruction has not been acquired (S140: No), the CPU 22 returns the process to S126 and executes the processes after S126. When the retransmission instruction is acquired (S140: Yes), the CPU 22 sets “ON” in the retransmission flag (S142). Thereafter, the CPU 22 returns the process to S110 of FIG. 4 and executes the processes after S110. In this case, in S110, according to the destination information associated with the communication number to be processed in the transmission history memory (see “052-11-2222” based on FIG. 2D), the same communication number to be processed Of transmission data (refer to “Data for communication No. 1” based on FIG. 3B) stored in the transmission data storage location associated with (refer to “Address 1” based on FIG. 2D) Facsimile transmission is started. That is, in this S110, the facsimile transmission that failed in the previous S110 is retransmitted.

<Mobile terminal processing>
Mobile terminal processing executed by the mobile terminal device 50 will be described with reference to FIGS. 6 and 7. The mobile terminal process is started when a user of the mobile terminal device 50 (operation target user) operates the operation unit 60 and inputs an execution instruction for starting a computer program for mobile terminal processing. Along with the input of the execution instruction, the CPU 52 controls the display unit 58 to display a transmission operation screen including the operation unit 60 using the touch panel function. By this control, a transmission operation screen as shown in FIG. 8A (however, the other party information such as “052-11-2222” is not displayed) is displayed on the display unit 58. The “Resend” button on the operation unit 60 is in a state where it cannot be pressed (the halftone dot in the “Resend” part in FIG. 8A indicates this state). In addition, for example, after the execution instruction is input, the operation target user performs an operation of designating transmission destination data and destination data as transmission data destination. As the destination information is input, the input destination information is displayed on the transmission operation screen (see FIG. 8A). In accordance with this operation, the CPU 52 specifies destination information and transmission data. Thereafter, the user to be operated presses the “Send” button. The user to be operated holds the portable terminal device 50 over the communication device 20 at a predetermined timing before or after pressing the “Send” button.

  The CPU 52 that has started the portable terminal process determines whether NFC has been established with the communication device 20 (S200). In establishing NFC, the connection request described in relation to S100 of FIG. 4 is transmitted from the short-range communication unit 64 to the communication device 20. Then, the CPU 52 performs pairing in NFC and establishes NFC with the communication device 20. When NFC is not established because the mobile terminal device 50 is not held over the communication device 20 (S200: No), the CPU 52 repeatedly executes S200. When NFC is established (S200: Yes), the CPU 52 performs control to transmit the terminal ID and partner information of the own device from the short-range communication unit 64 to the communication device 20 (S202). By this control, the terminal ID and the partner information are transmitted from the short-range communication unit 64 to the communication device 20 by NFC.

  Subsequently, the CPU 52 controls processing for establishing wireless LAN communication with the communication device 20 in accordance with the Wi-Fi handover. Then, the CPU 52 determines whether or not wireless LAN communication has been established with the communication device 20 (S204). For example, when the process for establishing the wireless LAN communication is being executed and the wireless LAN communication is not established (S204: No), the CPU 52 continues to control the process described above. When the wireless LAN communication is established (S204: Yes), the CPU 52 performs control to transmit the specified transmission data together with the destination information from the wireless LAN communication unit 66 to the communication device 20 (S206). With this control, transmission data is transmitted from the wireless LAN communication unit 66 to the communication device 20 by wireless LAN communication.

  After executing S206, the CPU 52 determines whether or not a certain period of time has elapsed since the completion of transmission of transmission data by wireless LAN communication (S208). The fixed time as the determination condition is appropriately set in consideration of various conditions. For example, the fixed time is a time corresponding to the above-described storage time (see S126 in FIG. 5). When the predetermined time has elapsed (S208: Yes), the CPU 52 ends the portable terminal process. When the predetermined time has not elapsed (S208: No), the CPU 52 determines whether or not a transmission stop notification has been acquired (S210). The transmission stop notification is transmitted from the communication device 20 by wireless LAN communication and received by the wireless LAN communication unit 66 in S128 of FIG. The CPU 52 acquires a transmission stop notification via the wireless LAN communication unit 66. When the transmission stop notification is acquired (S210: Yes), the CPU 52 ends the mobile terminal process.

  When the transmission stop notification has not been acquired (S210: No), the CPU 52 shifts the process to S212 in FIG. 7 and determines whether NFC is established with the communication device 20 (S212). When NFC is not established (S212: No), the CPU 52 returns the process to S208 of FIG. 6 and executes the processes after S208. In order to establish NFC, the portable terminal device 50 must be held over the communication device 20. That is, it is necessary to bring the mobile terminal device 50 and the communication device 20 close to a distance where NFC is possible. If the method of holding the portable terminal device 50 over the communication device 20 is inappropriate, or if the portable terminal device 50 is not held over the communication device 20, NFC is not established. When the portable terminal device 50 is held over the communication device 20, the connection request described in relation to S130 of FIG. 5 is transmitted from the short-range communication unit 64 to the communication device 20 in establishing NFC. The user to be operated re-executes the failed facsimile transmission according to the communication error screen displayed on the display unit 32 when the facsimile transmission started in S110 of FIG. 4 fails (see S112 of FIG. 4: No). When transmitting, the operation as described above is performed.

  When NFC is established (S212: Yes), the CPU 52 performs control to transmit the terminal ID from the short-range communication unit 64 to the communication device 20 (S214). By this control, the terminal ID is transmitted from the short-range communication unit 64 to the communication device 20 by NFC. Subsequently, the CPU 52 acquires a response from the communication device 20 received via the short-range communication unit 64 (S216). The CPU 52 determines whether or not the acquired response is a resendable notification (S218). The resendable notification is transmitted from the communication device 20 by NFC and received by the short-range communication unit 64 in S138 of FIG.

  When the acquired response is not a resendable notification (S218: No), the CPU 52 returns the process to S208 of FIG. 6 and executes the processes after S208. When the acquired response is a resendable notification (S218: Yes), the CPU 52 performs control to display information indicating that resend is possible on the display unit 58 according to the resendable notification (S220). By this control, information indicating that retransmission is possible is displayed on the display unit 58. In the present embodiment, information indicating that retransmission is possible is displayed in a state where the “Resend” button of the operation unit 60 on the transmission operation screen displayed on the display unit 58 can be pressed (FIG. 8B). reference). When switching the display state of the “Resend” button (see FIGS. 8A and 8B), the contents indicate that the facsimile transmission has failed and / or that the failed facsimile transmission can be instructed to be retransmitted. A message screen may be displayed on the display unit 58.

  Next, the CPU 52 determines whether or not a certain period of time has elapsed since the completion of transmission of transmission data by wireless LAN communication (S222). S222 is the same processing as S208 of FIG. 6, and the predetermined time is the same as S208 of FIG. 6 described above. When the predetermined time has elapsed (S222: Yes), the CPU 52 ends the portable terminal process. When the predetermined time has not elapsed (S222: No), the CPU 52 determines whether or not the user to be operated has pressed the “Resend” button of the operation unit 60 using the touch panel function (S224). The CPU 52 determines S224 according to whether or not the “Resend” button (see FIG. 8B) of the operation unit 60 on the transmission operation screen is pressed. The user to be operated re-executes the failed facsimile transmission according to the communication error screen displayed on the display unit 32 when the facsimile transmission started in S110 of FIG. 4 fails (see S112 of FIG. 4: No). To send, press the “Resend” button.

  When the “Resend” button has not been pressed (S224: No), the CPU 52 returns the process to S222 and executes S222. When the “Resend” button is pressed (S224: Yes), the CPU 52 controls processing for establishing NFC with the communication apparatus 20, and determines whether NFC is established (S226). When NFC is not established (S226: No), the CPU 52 returns the process to S222 and executes the processes after S222. In order to establish NFC, the mobile terminal device 50 must be held over the communication device 20 at a predetermined timing before or after the “Resend” button is pressed. Whether or not NFC is established is the same as in the case of S212 described above, and a description thereof will be omitted.

  When NFC is established (S226: Yes), the CPU 52 performs control to transmit a retransmission instruction from the short-range communication unit 64 to the communication device 20 (S228). With this control, a retransmission instruction is transmitted from the short-range communication unit 64 to the communication device 20 by NFC. After executing S228, the CPU 52 returns the process to S208 in FIG. 6 and executes the processes after S208.

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

  (1) In the communication device 20, when the facsimile transmission started in S110 of FIG. 4 based on the request from the mobile terminal device 50 has failed (see S112 of FIG. 4: No), the mobile terminal device 50 returns to the terminal again. The ID is acquired (see 132 in FIG. 5), and it is determined whether or not the acquired terminal ID matches the terminal ID associated with the communication number to be processed (see S134 in FIG. 5). If the two terminal IDs match (see S134 in FIG. 5: Yes), the transmission stored in the transmission data memory according to the destination information stored in the transmission history memory in association with the communication number to be processed. The data is transmitted again by facsimile (see S110 in FIG. 4). Therefore, it is possible to execute retransmission of the failed facsimile transmission after identifying the portable terminal device 50 related to the failed facsimile transmission by matching the terminal ID. Security regarding retransmission of failed facsimile transmissions can be ensured.

  (2) In the communication device 20, when the terminal ID acquired in S132 matches the terminal ID associated with the communication number to be processed (see S134 in FIG. 5: Yes), a retransmittable notification is transmitted (FIG. 5). 5 (see S138 in FIG. 5), in response to this, when a retransmission instruction is acquired (see S140 in FIG. 5: Yes), according to the destination information stored in the transmission history memory in association with the communication number to be processed, The transmission data stored in the transmission data memory is transmitted by facsimile again (see S110 in FIG. 4). Therefore, it is possible to notify the mobile terminal device 50 that the facsimile transmission has failed or that the failed facsimile transmission can be retransmitted. The failed facsimile transmission can be retransmitted based on the retransmission instruction transmitted from the portable terminal device 50 in response to the retransmittable notification. An operation for re-transmission can be smoothly performed in cooperation with the mobile terminal device 50. With regard to retransmission of failed facsimile transmissions, the communication device 20 can be provided with suitable operability.

  (3) In the communication device 20, when the facsimile transmission started in S110 of FIG. 4 is successful based on the request from the mobile terminal device 50 (see S112: Yes in FIG. 4), the communication number for the successful facsimile transmission Each information including the (communication number to be processed) and the destination information associated with the communication number to be processed is deleted from the transmission history memory (see S120 in FIG. 4). When the facsimile transmission started in S110 of FIG. 4 fails (see S112 of FIG. 4: No), each piece of information including the communication number to be processed and the destination information associated with the communication number to be processed is It is assumed that control such as immediate deletion from the transmission history memory is not executed. Therefore, when the facsimile transmission is successful, it is possible to prevent each person including information on the other party of the successful facsimile transmission from being acquired or used by another person. Security can be ensured for each piece of information including the destination information of successful facsimile transmission. If the facsimile transmission fails, the information including the destination information can be stored in the transmission history memory and used for retransmission.

  If the facsimile transmission fails (see S112 in FIG. 4) and the storage time has passed (see S126 in FIG. 5: Yes), the destination information is deleted from the transmission history memory (see S120 in FIG. 4). ) Therefore, as with the case where the facsimile transmission is successful, it is possible to ensure security for each piece of information including the destination information. When deleting each piece of information including the destination information associated with the communication number to be processed from the transmission history memory, the information is stored in this storage location according to the transmission data storage location associated with the transmission target communication number. The transmitted data is deleted from the transmission data memory (see S118 in FIG. 4). Therefore, it is possible to prevent the transmission data stored in the transmission data memory together with each piece of information including the destination information from being acquired or used by others.

The user to be operated confirms the displayed destination information and determines whether an incorrect input has been made. The mobile terminal device 50 accepts re-input of the partner information in response to an erroneous input. If the displayed destination information is correct, re-inputting the destination information may be omitted. Also, re-input may be accepted regardless of whether it is correct or incorrect. When the partner information is re-input, the CPU 52 acquires the re-input partner information and performs control to transmit new partner information together with the retransmission instruction in S228 of FIG.

  In the communication device 20, the CPU 22 executes S142 in FIG. 5 and then returns the processing to S110 in FIG. 4. In accordance with the new partner information acquired together with the retransmission instruction via the short-range communication unit 38, the transmission history memory The facsimile transmission control for the transmission data stored in the transmission data storage location associated with the communication number to be processed is started. As a result, even if the destination information input earlier in the mobile terminal device 50 is incorrect, facsimile transmission can be executed again according to the input destination information again. Note that the resendable notification may include the destination information, and the resendable notification including the destination information may be transmitted in S138 of FIG.
