<Processing sequence>
Processing executed in the communication system 10 when a telephone call is made with the user of the counterpart device 90 and image data is transmitted by facsimile to the counterpart device 90 will be described with reference to FIGS. In the present embodiment, a transmission method in which a telephone call is made with the user of the counterpart device 90 and image data is transmitted by facsimile to the counterpart device 90 is referred to as “manual transmission”. In manual transmission, the user sets a document to be transmitted on the multi-function device 60 (T1). When the set document is detected by the document sensor 72, a call state request is transmitted from the multi-function device 60 to the communication device 20 (T2). In the present embodiment, it is assumed that no telephone call using any of the mobile terminals 40A and 40B is performed. In the communication device 20, a non-call notification is transmitted as a response to the request to the multi-function device 60 that is the request source (T3). In the multi-function device 60 that has received the non-call notification as a response, the non-call screen is displayed on the display unit 78 (T4). The non-call screen indicates that any mobile terminal 40 is in a non-call state. The non-call screen includes a telephone number of the counterpart device 90, terminal information for identifying the mobile terminal 40 to be used, and a message that prompts an input of a manual transmission execution instruction.

  Next, the user operates the operation unit 76 to input a manual transmission execution instruction (T5). At that time, the user operates the operation unit 76 to identify the telephone number of the destination device 90 and terminal information for identifying the mobile terminal 40 to be used (one of the mobile terminals 40A and 40B based on FIG. 1). Information). In the multi-function device 60, the set original is read by the scanner unit 70, and image data is formed (T6). When all set originals are read and image data corresponding to all originals is formed, the multifunction device 60 transmits a first manual transmission request corresponding to the execution instruction described above to the communication device 20. (T7). At that time, image data, a telephone number, and terminal information are transmitted together. The first manual transmission request is a notification requesting that a call is made to the counterpart device 90 of the input telephone number and manual transmission is performed. The communication device 20 receives the first manual transmission request and the like. Thereafter, in the communication device 20, the received telephone number is set as a call destination (T8). Specifically, the telephone number is stored in the RAM 26. At this time, terminal information and image data are also stored in the RAM 26. Subsequently, in the communication device 20, a call start request is transmitted to the mobile terminal 40 (call target mobile terminal 40) identified by the terminal information (T9). At that time, the manual transmission notification and the telephone number received based on T7 are transmitted. The call start request is a notification for requesting the mobile terminal 40 to execute a call operation. The manual transmission notification is a notification indicating that this call is a call for manual transmission. When the terminal information received based on T7 is information for identifying the mobile terminal 40A, the transmission at T9 is performed to the mobile terminal 40A.

  In the portable terminal 40 to be called, in response to T9, a ringing tone is output from the speaker 56 (T10), and a manual transmission screen is displayed on the display unit 52 (T11). The manual transmission screen includes information corresponding to the manual transmission notification and a telephone number. The information corresponding to the manual transmission notification is information indicating that this call is a call for manual transmission. Subsequently, in the call target portable terminal 40, a call start response is transmitted to the communication device 20 (T12). The call start response is a response notifying that the call operation has started in accordance with T9. The communication device 20 receives the call start response. Thereafter, the communication device 20 transmits a call start response to the multi-function device 60 (T13). In the multi-function device 60 that has received the call start response, a calling screen is displayed on the display unit 78 (T14). The calling screen indicates that the mobile terminal 40 identified by the terminal information at T7 is being called. Thereafter, the processing in the communication system 10 shifts to the procedure shown in FIG.

  The user listens to the ringing tone at T10 and performs an operation for responding to the calling on the portable terminal 40 (T15). In the portable terminal 40, in response to T15, an extension start notification is transmitted to the communication device 20 (T16), and communication with the communication device 20 is controlled (T17). As a result, a wireless connection is established between the communication device 20 and the mobile terminal 40 to be called, and communication between both devices becomes possible. In the portable terminal 40, the pre-transmission call screen is displayed on the display unit 52 (T18). The pre-transmission call screen indicates that the call is in progress before facsimile transmission in manual transmission. In the communication device 20 in which communication with the portable terminal 40 is controlled by T17, a terminal communication start notification is transmitted to the multi-function device 60 (T19). The terminal communication start notification is a notification indicating that communication with the mobile terminal 40 has started. In the multi-function device 60, the terminal communication start notification is received, and a communication start screen is displayed on the display unit 78 (T20). The communication start screen indicates that communication is started between the mobile terminal 40 and the communication device 20 that are being called.

  Next, in the communication device 20, the call destination set at T8 in FIG. 2 is acquired (T21). Specifically, the telephone number stored in the RAM 26 is acquired at T8. Subsequently, in the communication device 20, the second communication unit 30 closes the line, connects the mobile terminal 40 to the communication line 100 side, and controls the calling process according to the telephone number acquired in T21. (T22). As a result, calling of the counterpart device 90 is started via the communication line 100 (T23). When there is an external line response from the counterpart device 90 (T24), the communication device 20 and the counterpart device 90 are connected via the communication line 100. In the communication device 20, a call between the mobile terminal 40 and the counterpart device 90 is relayed. A user of the communication system 10 communicates with the user of the counterpart device 90 using the mobile terminal 40. The user of the communication system 10 can confirm the other party by this call. Thereafter, the processing in the communication system 10 shifts to the procedure shown in FIG.

  When starting facsimile transmission of image data by manual transmission, the user operates a transmission start key included in the operation unit 50 (T25). The transmission start key is an operation key associated with the start of facsimile transmission. When the transmission start key is operated on the portable terminal 40, the portable terminal 40 transmits a transmission start instruction to the communication device 20 (T26). In the portable terminal 40, after T26, communication with the communication device 20 (communication for a call) is terminated (T27). The communication device 20 receives the transmission start instruction. Subsequently, in the communication device 20, a FAX transmission start notification is transmitted to the multi-function device 60 and the portable terminal 40 (T28 and T29). The FAX transmission start notification is a notification indicating that facsimile transmission of image data is started. The mobile terminal 40 to which the FAX transmission start notification is transmitted is the mobile terminal 40 to be called and the mobile terminal 40 that has transmitted the transmission start instruction. In the MFP 60 that has received the FAX transmission start notification, a transmission start screen is displayed on the display unit 78 (T30). Similarly, in the portable terminal 40 that has received the FAX transmission start notification, a transmission start screen is displayed on the display unit 52 (T31). The transmission start screen indicates that the image data is transmitted to the counterpart device 90 by facsimile.

  Next, in the communication device 20, facsimile transmission via the communication line 100 is controlled for the image data stored in the RAM 26. First, the communication apparatus 20 transmits a FAX transmission signal to the partner apparatus 90 via the communication line 100, and the partner apparatus 90 receives this FAX transmission signal (T32). The counterpart apparatus 90 transmits a FAX reception signal in response to the reception of the FAX transmission signal, and the communication apparatus 20 receives this FAX reception signal (T33). As described above, for example, the capability related to facsimile transmission is negotiated by the transmission / reception of the FAX transmission signal and the FAX reception signal performed between the communication apparatus 20 and the counterpart apparatus 90. Thereafter, facsimile communication via the communication line 100 is executed between the communication device 20 and the counterpart device 90 (T34). At this time, the image data stored in the RAM 26 is transmitted by facsimile from the communication device 20 to the counterpart device 90.

  At a predetermined timing after all the image data is transmitted by facsimile, the communication device 20 and the counterpart device 90 each perform line opening and disconnect from the communication line 100 (T35 and T36). After executing T35, the communication device 20 transmits a FAX transmission end notification to the multi-function device 60 and the portable terminal 40 (T37 and T38). The FAX transmission end notification is a notification indicating that the facsimile transmission of image data has ended. In the multi-function device 60 that has received the FAX transmission end notification, a transmission completion screen is displayed on the display unit 78 (T39). Similarly, in the portable terminal 40 that has received the FAX transmission start notification, a transmission completion screen is displayed on the display unit 52 (T40). The transmission completion screen indicates that the image data has been transmitted to the counterpart apparatus 90 by facsimile. In the multi-function device 60 and the portable terminal 40, a transmission completion screen is displayed for a predetermined time. Thereafter, the display on the display unit 78 of the multi-function device 60 and the display on the display unit 52 of the portable terminal 40 transition from the transmission completion screen to the standby screen (T41 and T42). The standby screen indicates that it is on standby.

<Multifunction machine processing>
The multi-function processing will be described with reference to FIGS. The multifunction device process is a process executed by the multifunction device 60 for manual transmission. The multifunction machine process is started when the user sets a document to be transmitted on the multifunction machine 60 and the document sensor 72 detects the document (see T1 in FIG. 2). The CPU 62 that has started the MFP process controls to transmit a call state request from the fifth communication unit 68 to the communication device 20 (S100). S100 corresponds to T2 in FIG. As a response to the call state request, the CPU 62 determines whether or not a call notification is received by the fifth communication unit 68 (S102). The notification during a call includes the telephone number of the partner apparatus 90 during the call and terminal information for identifying the mobile terminal 40 during the call. The in-call notification is transmitted in S208 of FIG.

  When a notification during a call is received (S102: Yes), the CPU 62 controls the display unit 78 to display a screen during a call (S104). The busy screen includes the telephone number and terminal information included in the busy notification. By visually recognizing the screen during a call displayed on the display unit 78, the user can specify the telephone number of the other party and the portable terminal 40 during the call. It can be determined whether or not to transmit. The CPU 62 controls the display unit 78 to display an input screen that prompts input of a telephone number, terminal information, and an execution instruction at a timing when a predetermined time has elapsed after displaying the screen during a call. When manually transmitting to the destination device 90 of the specified telephone number, the user operates the operation unit 50 and inputs a manual transmission execution instruction. When inputting the execution instruction, the user inputs the telephone number of the counterpart device 90 and the terminal information. The CPU 62 determines whether or not an execution instruction has been input with the telephone number and terminal information being input (S106). When the execution instruction is not input within a certain time after executing S104, or when the instruction to cancel manual transmission is input via the operation unit 76, the CPU 62 denies S106 (S106: No), The process proceeds to S140 in FIG.

  When the execution instruction is input with the telephone number and the terminal information being input (S106: Yes), the CPU 62 controls reading of the document by the scanner unit 70 (S108). The scanner unit 70 reads all originals set in the multi-function device 60. As a result, image data corresponding to all the read originals is formed. Subsequently, the CPU 62 sends the second manual transmission request corresponding to the manual transmission execution instruction, the input telephone number and terminal information, and the image data formed in S108 from the fifth communication unit 68 to the communication device 20. Control to transmit (S110). The second manual transmission request is a notification for requesting manual transmission to the counterpart device 90 during a call. Thereafter, the CPU 62 shifts the processing to S130 of FIG.

  When the call notification is not received (S102: No), it is determined whether a non-call notification is received as a response to the call state request (S112). When the non-call notification is not received (S112: No), the CPU 62 shifts the process to S138 of FIG. For example, such a result is obtained when the communication device 20 is powered off and cannot communicate with the communication device 20. When the non-call notification is received (S112: Yes), the CPU 62 controls the display unit 78 to display a non-call screen (S114). S114 corresponds to T4 in FIG. In response to the display of the non-call screen, the user operates the operation unit 76 to input the telephone number of the counterpart device 90 and terminal information for identifying the mobile terminal 40 to be used, and then input an execution instruction (see FIG. 2 T5). The CPU 62 determines whether or not a manual transmission execution instruction is input in a state where the telephone number and the terminal information are input (S116). When the execution instruction is not input (S116: No), the CPU 62 shifts the process to S140 of FIG. For example, after executing S114, if an execution instruction is not input within a certain period of time, or if an instruction to cancel manual transmission is input via the operation unit 76, the determination in S116 is negative (S116: No). ).

  When an execution instruction is input in a state where the telephone number and the terminal information are input (S116: Yes), the CPU 62 controls reading of the original by the scanner unit 70 (S118). S118 corresponds to T6 in FIG. S118 is performed in the same manner as S108. The description regarding S118 is omitted. Subsequently, the CPU 62 controls the fifth communication unit 68 to transmit the first manual transmission request, the input telephone number and terminal information, and the image data formed in S118 to the communication device 20 (S120). ). S120 corresponds to T7 in FIG. Thereafter, the CPU 62 determines whether or not the call start response transmitted from the communication device 20 has been received by the fifth communication unit 68 (S122). The call start response is transmitted in S226 of FIG. When the call start response is not received (S122: No), the CPU 62 shifts the process to S140 of FIG. When S122 is denied (S122: No), the fifth communication unit 68 receives a call failure notification. The call failure notification is transmitted in S224 of FIG. When the call start response is received (S122: Yes, refer to T13 in FIG. 2), the CPU 62 controls the display unit 78 to display the calling screen (S124). S124 corresponds to T14 in FIG.

  After executing S124, the CPU 62 determines whether or not the terminal communication start notification transmitted from the communication device 20 is received by the fifth communication unit 68 (S126). The terminal communication start notification is transmitted in S234 of FIG. When the terminal communication start notification is not received (S126: No), the CPU 62 shifts the process to S140 of FIG. If S126 is negative (S126: No), the fifth communication unit 68 receives a call non-response notification. The call non-response notification is transmitted in S232 of FIG. When the terminal communication start notification is received (S126: Yes, see T19 in FIG. 3), the CPU 62 controls the display unit 78 to display a communication start screen (S128). S128 corresponds to T20 in FIG. Thereafter, the CPU 62 shifts the processing to S130 of FIG.

  In S <b> 130 of FIG. 6, the CPU 62 determines whether or not the fifth communication unit 68 has received a FAX transmission start notification transmitted from the communication device 20. The FAX transmission start notification is transmitted during the facsimile transmission process in S246 of FIG. When the FAX transmission start notification is not received (S130: No), the CPU 62 shifts the process to S140. When S130 is denied (S130: No), the fifth communication unit 68 receives a FAX transmission failure notification. The FAX transmission failure notification is transmitted in S242 of FIG. When the FAX transmission start notification is received (S130: Yes, see T28 in FIG. 4), the CPU 62 controls the display unit 78 to display a transmission start screen (S132). S132 corresponds to T30 in FIG. Subsequently, the CPU 62 determines whether or not the FAX transmission end notification transmitted from the communication device 20 is received by the fifth communication unit 68 (S134). The FAX transmission end notification is transmitted in S250 of FIG.

  When the FAX transmission end notification is not received (S134: No), the CPU 62 continues to display the transmission start screen. In this case, the communication device 20 continues the facsimile transmission process (see S246 in FIG. 8), and image data is transmitted from the second communication unit 30 to the counterpart device 90 by facsimile. In the multifunction device 60, the transmission start screen is continuously displayed correspondingly. When the FAX transmission end notification is received (S134: Yes, see T37 in FIG. 4), the CPU 62 controls the display unit 78 to display a transmission completion screen for a certain time (S136). S136 corresponds to T39 in FIG. After executing S136, the CPU 62 shifts the process to S144.

  When S112 described above is denied (S112: No) and the process proceeds to S138, the CPU 62 controls the display unit 78 to display a communication error screen for a certain period of time. After displaying the communication error screen, the CPU 62 proceeds to S140 in FIG. If any of S106, S116, S122, or S126 described above is denied (S106, S116, S122, S126: No), or if the process proceeds from S138 to S140, the CPU 62 sends a manual transmission to the display unit 78. Control is performed so as to display a cancel screen indicating that cancellation was not possible (S140). After displaying the transmission completion screen on the display unit 78 in S136 or displaying the cancel screen in S140, the CPU 62 waits for the display on the display unit 78 to wait from the transmission completion screen or the cancellation screen after a certain period of time has elapsed. Control is performed so as to transition to the screen (S144). S144 performed after S136 corresponds to T41 of FIG. After executing S144, the CPU 62 ends the multifunction peripheral process.

<Communication device processing>
The communication device processing will be described with reference to FIGS. The communication device process is a process executed by the communication device 20 regarding manual transmission. The CPU 22 that has started the communication device process determines whether or not the information transmitted from the multi-function device 60 has been received by the third communication unit 32 (S200). When no information is received (S200: No), the CPU 22 repeatedly executes S200. When any information is received (S200: Yes), the CPU 22 determines the type of the received information (S202). The information received here is either a call state request, a first manual transmission request, or a second manual transmission request. The call state request is transmitted in S100 of FIG. The first manual transmission request is transmitted in S120 of FIG. 5 together with the telephone number, terminal information, and image data. The second manual transmission request is transmitted in S110 of FIG. 5 together with the telephone number, terminal information, and image data.

  When the received information is a call state request (S202: Call state request, see T2 in FIG. 2), the CPU 22 determines whether or not the mobile terminal 40 is in a call (S204). Whether or not a call is in progress is determined, for example, according to whether or not a call between the mobile terminal 40 and the counterpart device 90 is being relayed. The determination may be made according to whether or not communication with the counterpart apparatus 90 via the communication line 100 is controlled. When all the mobile terminals 40 are not in a call (S204: No), the CPU 22 controls to transmit a non-call notification from the third communication unit 32 to the multi-function device 60 (S206). S206 corresponds to T3 in FIG. When any of the mobile terminals 40 (based on FIG. 1, the mobile terminal 40A or the mobile terminal 40B) is busy (S204: Yes), the CPU 22 notifies the multi-function device 60 during the call from the third communication unit 32. (S208). As described above, the in-call notification includes the telephone number of the partner apparatus 90 that is in a call and the terminal information that identifies the mobile terminal 40 that is in the call. When the communication via the communication line 100 is started, the CPU 22 stores the received telephone number of the counterpart device 90 in the RAM 26 at the start of the communication. The CPU 22 adds the telephone number of the counterpart device 90 stored in the RAM 26 to the busy notification. After executing S206 or S208, the CPU 22 returns the process to S200.

  When the received information is a second manual transmission request (S202: second manual transmission request), the CPU 22 receives the image data, telephone number, and terminal received by the third communication unit 32 together with the second manual transmission request. Information is stored in the RAM 26 (S210). Subsequently, the CPU 22 determines whether or not the telephone number stored in the RAM 26 in S210 matches the telephone number stored in the RAM 26 at the start of communication during a call (S212). When the telephone numbers match (S212: Yes), the CPU 22 controls the first communication unit 28 to transmit a forced disconnection instruction and a disconnection reason notification to the mobile terminal 40 that is talking (S214). The forced disconnection instruction is an instruction for forcibly terminating the call between the mobile terminal 40 and the counterpart device 90. The disconnect reason notification is a notification indicating the reason for forcibly terminating the call. The mobile terminal 40 that has received them ends the call (see S302 in FIG. 9), and displays a disconnect screen according to the disconnect reason notification on the display unit 52 for a certain period of time (see S303 in FIG. 9). After executing S214, the CPU 22 shifts the processing to S246 in FIG.

  If the telephone numbers do not match (S212: No), the CPU 22 controls the third communication unit 32 to transmit a FAX transmission failure notification to the multi-function device 60 (S216). The FAX transmission failure notification is a notification indicating that the facsimile transmission of the image data has failed. The reason for failure (phone number mismatch) may be added to the FAX transmission failure notification. In the multi-function device 60 that has received this, a cancel screen in accordance with the FAX transmission failure notification is displayed on the display unit 78 for a certain period of time (see S140 in FIG. 6). After executing S216, the CPU 22 returns the process to S200.

  When the received information is the first manual transmission request (S202: first manual transmission request, see T7 in FIG. 2), the CPU 22 receives the telephone number received by the third communication unit 32 together with the first manual transmission request. The terminal information and the image data are stored in the RAM 26 (S218). At this time, the telephone number is set and managed as a call destination for manual transmission. S218 corresponds to T8 in FIG. Subsequently, the CPU 22 sends a call start request, a manual transmission notification, and S218 to the portable terminal 40 (calling portable terminal 40) identified by the terminal information stored in the RAM 26 in S218 from the first communication unit 28. In step S220, the telephone number stored in the RAM 26 is controlled to be transmitted. S220 corresponds to T9 in FIG.

  After executing S220, the CPU 22 determines whether or not the first communication unit 28 has received a call start response transmitted from the mobile terminal 40 to be called (S222). The call start response is transmitted in S322 of FIG. When the call start response is not received (S222: No), the CPU 22 controls the third communication unit 32 to transmit a call failure notification to the multi-function device 60 (S224). The call failure notification is a notification indicating that calling of the mobile terminal 40 to be called has failed. When S222 is denied (S222: No), the first communication unit 28 receives a call rejection notification. The call rejection notification is a notification indicating that the mobile terminal 40 to be called cannot be used, and is transmitted in S316 of FIG. After executing S224, the CPU 22 returns the process to S200. When the call start response is received (S222: Yes, see T12 in FIG. 2), the CPU 22 shifts the process to S226 in FIG.

  In S <b> 226 of FIG. 8, the CPU 22 controls the third communication unit 32 to transmit the received call start response to the multi-function device 60. S226 corresponds to T13 in FIG. Subsequently, the CPU 22 determines whether or not the extension start notification transmitted from the mobile terminal 40 to be called is received by the first communication unit 28 (S228). When the extension start notification is not received within a certain time after S212 (S228: No), the CPU 22 controls the first communication unit 28 to transmit a call stop request to the mobile terminal 40 to be called (S230). . The call stop request is a notification requesting the mobile terminal 40 to stop the call operation. Thereafter, the CPU 22 controls the third communication unit 32 to transmit a call non-response notification to the multi-function device 60 (S232). The call non-response notification is a notification indicating that there is no response to the call in the mobile terminal 40 to be called. In the multi-function device 60 that has received this, a cancel screen according to the call non-response notification is displayed on the display unit 78 for a certain period of time (see S140 in FIG. 6). After executing S232, the CPU 22 returns the process to S200.

  When the extension start notification is received (S228: Yes, see T16 in FIG. 3), the CPU 22 controls the third communication unit 32 to transmit a terminal communication start notification to the multi-function device 60 (S234). The extension start notification is transmitted in S330 of FIG. Subsequently, the CPU 22 controls to connect the portable terminal 40 to be called to the communication line 100 side (S236). Thereby, for example, the voice input to the microphone 54 can be output from the second communication unit 30 to the communication line 100, and the voice of the other party received by the second communication unit 30 via the communication line 100 is output from the speaker 56. Can be output. Thereafter, the CPU 22 controls the calling process according to the telephone number stored in the RAM 26 in S210 (S238). Specifically, the CPU 22 controls line closing in the second communication unit 30. Accordingly, the second communication unit 30 closes the line. Subsequently, the CPU 22 sends a telephone number from the second communication unit 30 to the communication line 100. S236 and S238 correspond to T21 and T22 in FIG.

  Next, the CPU 22 determines whether or not a call end instruction is received by the first communication unit 28 (S240). The call end instruction is an instruction indicating that the call with the partner apparatus 90 is to be ended. The call end instruction is transmitted in S338 of FIG. When a call end instruction is received (S240: Yes), the CPU 22 transmits a FAX transmission failure notification from the third communication unit 32 to the multi-function device 60, and transmits from the first communication unit 28 to the portable terminal 40 to be called. Control is performed (S242). Regarding the FAX transmission failure notification transmitted here, the reason for failure (call termination) may be added as in the case of S216 in FIG. In the multi-function device 60 that has received this, a cancel screen in accordance with the FAX transmission failure notification is displayed on the display unit 78 for a certain period of time (see S140 in FIG. 6). As with the multi-function device 60, the cancel screen according to the FAX transmission failure notification is also displayed on the display unit 52 for a certain period of time for the portable terminal 40 (see S304 in FIG. 9). After executing S242, the CPU 22 shifts the process to S248.

  When the call end instruction is not received (S240: No), the CPU 22 determines whether or not the transmission start instruction is received by the first communication unit 28 (S244). The transmission start instruction is transmitted in S342 of FIG. When the transmission start instruction is not received (S244: No), the CPU 22 returns the process to S240, and repeats S240 and S244 until the call end instruction or the transmission start instruction is received. When the transmission start instruction is received (S244: Yes, see T26 in FIG. 4), the CPU 22 controls the facsimile transmission process (S246). In S246, the CPU 22 controls to transmit a FAX transmission start notification from the third communication unit 32 to the multi-function device 60 (see T28) and from the first communication unit 28 to the portable terminal 40 to be called (T29). reference). Thereafter, the CPU 22 ends the relay between the portable terminal 40 and the counterpart device 90, and transmits the image data stored in the RAM 22 in S210 of FIG. 7 by facsimile from the first communication unit 28 to the counterpart device 90. (See T34 in FIG. 4). At this time, a FAX transmission signal and a FAX reception signal are transmitted and received between the first communication unit 28 and the counterpart device 90 (see T32 and T33 in FIG. 4). The image data is transmitted by facsimile from the first communication unit 28 to the counterpart apparatus 90 via the communication line 100. After executing S246, the CPU 22 shifts the process to S248.

  In S248, the CPU 22 controls the line opening in the second communication unit 30. The second communication unit 30 opens the line. As a result, communication with the counterpart device 90 for manual transmission ends. S248 corresponds to T35 in FIG. Subsequently, the CPU 22 controls to transmit a FAX end notification from the third communication unit 32 to the multi-function device 60 and from the first communication unit 28 to the portable terminal 40 to be called (S250). S250 corresponds to T37 and T38 in FIG. After executing S250, the CPU 22 returns the process to S200 of FIG. The CPU 22 repeats the communication device process until the power of the communication device 20 is turned off.

<Mobile terminal processing>
The portable terminal process will be described with reference to FIGS. 9 and 10. The portable terminal process is a process executed by the portable terminal 40 regarding manual transmission. CPU42 which started the portable terminal process judges whether the information transmitted from the communication apparatus 20 was received by the 4th communication part 48 (S300). When no information is received (S300: No), the CPU 42 repeatedly executes S300. When any information is received (S300: Yes), the CPU 42 determines the type of the received information (S301). The information received here is either a forced disconnection instruction, a disconnect reason notification, a call start request, a FAX transmission failure notification, or a FAX transmission start notification. The forced disconnection instruction and disconnection reason notification are transmitted in S214 of FIG. The call start request is transmitted in S220 of FIG. The FAX transmission failure notification is transmitted in S242 of FIG. The FAX transmission start notification is transmitted during the facsimile transmission process in S246 of FIG.

  When the received information is a forced disconnection instruction and a disconnection reason notification (S301: forced disconnection instruction), the CPU 42 communicates with the communication device 20 in the fourth communication unit 48 (for calling) according to the forced disconnection instruction. The communication is controlled to end (S302). In this case, the call between the portable terminal 40 and the counterpart device 90 is forcibly terminated. Subsequently, in accordance with the disconnection reason notification, the CPU 42 controls the display unit 52 to display a disconnection screen including the disconnection reason for a predetermined time (S303). The user who visually recognizes the cutting screen recognizes the reason for cutting. Thereafter, the CPU 42 returns the process to S300 at a timing when a certain time has elapsed. When the received information is a FAX transmission failure notification (S301: FAX transmission failure notification), the CPU 42 displays on the display unit 52 a cancel screen indicating that manual transmission cannot be executed and canceled for a certain period of time. Control is performed as follows (S304). Thereafter, the CPU 42 returns the process to S300 at a timing when a certain time has elapsed.

  When the received information is a FAX transmission start notification (S301: FAX transmission start notification) (see T29 in FIG. 4), the CPU 42 controls the display unit 52 to display a transmission start screen (S306). S306 corresponds to T31 in FIG. Subsequently, the CPU 42 determines whether or not the FAX transmission end notification transmitted from the communication device 20 is received by the fourth communication unit 48 (S308). The FAX transmission end notification is transmitted in S250 of FIG. When the FAX transmission end notification is not received (S308: No), the CPU 42 continues to display the transmission start screen. In this case, the communication device 20 continues the facsimile transmission process (see S246 in FIG. 8), and the second communication unit 30 performs facsimile transmission of image data to the counterpart device 90. Corresponding to this, the mobile terminal 40 continuously displays the transmission start screen. When the FAX transmission end notification is received (S308: Yes, see T38 in FIG. 4), the CPU 42 controls the display unit 52 to display a transmission completion screen for a certain time (S310). After displaying the transmission completion screen on the display unit 52, the CPU 42 controls the display on the display unit 52 to transition from the transmission completion screen to the standby screen at a timing when a certain time has elapsed (S312). S310 and S312 respectively correspond to T40 and T42 in FIG. After executing S312, the CPU 42 returns the process to S300.

  When the received information is a call start response (S301: call start request), the CPU 42 determines whether or not the device is in a usable state (S314). If it cannot be used (S314: No), the CPU 42 controls the fourth communication unit 48 to transmit a call rejection notification to the communication device 20 (S316). For example, when the user is performing another operation not related to the mobile terminal process on the mobile terminal 40, S314 is denied (S314: No). After executing S316, the CPU 42 returns the process to S300. If it can be used (S314: Yes), the CPU 42 controls the calling operation (S318). As a result, a ringing tone is output from the speaker 56. The CPU 42 controls to display the manual transmission screen on the display unit 52 while controlling the calling operation (S320). Subsequently, the CPU 42 controls to transmit a call start response from the fourth communication unit 48 to the communication device 20 (S322). S318, S320, and S322 respectively correspond to T10, T11, and T12 of FIG. After executing S322, the CPU 42 shifts the processing to S324 in FIG.

  In S324 of FIG. 10, the CPU 42 determines whether or not a response instruction has been input. The response instruction is input by, for example, an operation in which the user picks up the mobile terminal 40 from an installation base (not shown). When the response instruction is not input (S324: No), the CPU 42 determines whether the fourth communication unit 48 has received the call stop request transmitted from the communication device 20 (S326). The call stop request is transmitted in S230 of FIG. When the call stop request is not received (S326: No), the CPU 42 returns the process to S324. When the call stop request is received (S326: Yes), the CPU 42 controls to stop the call operation started in S318 of FIG. 9 (S328). Thereafter, the CPU 42 returns the process to S300 of FIG. When a response instruction is input (S324: Yes, refer to T15 in FIG. 3), the CPU 42 controls to transmit an extension start notification from the fourth communication unit 48 to the communication device 20 (S330). S330 corresponds to T16 in FIG. Subsequently, the CPU 42 controls communication with the communication device 20 in the fourth communication unit 48. As a result, a wireless connection with the communication device 20 is established and communication is possible. When S236 in FIG. 8 is performed in the communication device 20, for example, the voice input to the microphone 54 can be output from the second communication unit 30 to the communication line 100. Further, the voice of the other party received by the second communication unit 30 via the communication line 100 can be output from the speaker 56. The CPU 42 controls to display the pre-transmission call screen on the display unit 52 (S334). S332 and S334 correspond to T17 and T18 in FIG. 3, respectively.

  Next, the CPU 42 determines whether or not a call end instruction has been input (S336). The call end instruction is input, for example, when the user who is on the call operates the disconnect key. The disconnect key is an operation key included in the operation unit 50 and is an operation key associated with an instruction to end a call. When a call end instruction is input (S336: Yes), the CPU 42 controls the fourth communication unit 48 to transmit a call end instruction to the communication device 20 (S338). After executing S338, the CPU 42 shifts the processing to S344. When the call end instruction is not input (S336: No), the CPU 42 determines whether or not a transmission start instruction is input (S340). As described above, the transmission start instruction is input, for example, when the user operates the transmission start key. When the transmission start instruction is not input (S340: No), the CPU 42 returns the process to S336. When the user continues the call with the user of the counterpart device 90, S336 and S340 are denied (S336, S340: No).

  When the user operates the transmission start key (see T25 in FIG. 4) and a transmission start instruction is input (S340: Yes), the CPU 42 transmits a transmission start instruction from the fourth communication unit 48 to the communication device 20. Control is performed (S342). S342 corresponds to T26 in FIG. After executing S342, the CPU 42 shifts the processing to S344. In S344, the CPU 42 controls to stop the communication control started in S332. Thereby, the call with the communication partner using the portable terminal 40 is terminated. S344 performed after S342 corresponds to T27 in FIG. After executing S344, the CPU 42 returns the process to S300 of FIG. The CPU 42 repeats the mobile terminal process until the power of the mobile terminal 40 is turned off.

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

  (1) In the communication system 10, image data can be transmitted by facsimile to the counterpart device 90 by manual transmission (see FIGS. 2 to 4). Therefore, it is possible to prevent the image data from being erroneously transmitted to the wrong partner apparatus. Further, the image data is transmitted by facsimile in a state where the call with the user of the counterpart device 90 is terminated (see T27 and T34 in FIG. 4, S246 in FIG. 8, and S344 in FIG. 10). For this reason, even when the telephone call and the facsimile transmission cannot be performed simultaneously, the other party can be confirmed by the telephone call, and the image data can be transmitted by facsimile after the confirmation. Furthermore, when a call with a predetermined partner has already been made (see S204 in FIG. 7: Yes), image data can be transmitted by facsimile to the partner device 90 of the other party (S102 in FIG. 5). (Yes, S104 to S110, S210, S212 in FIG. 7: Yes, S214, see S246 in FIG. 8). Therefore, the image data can be transmitted by facsimile to the counterpart apparatus 90 that is already in a call. If the call is not in progress (see S204 in FIG. 7: No), communication is established with the counterpart apparatus 90 that transmits image data by facsimile (see T21 to T24 in FIG. 3 and S238 in FIG. 8), and the same as above. The image data can be transmitted by facsimile to the destination apparatus 90 confirmed by the call.

  (2) When a user of the communication system 10 makes a call with the user of the counterpart device 90 using the mobile terminal 40, and then operates a disconnect key included in the operation unit 50 to input a call end instruction (see FIG. 10 (see S336: Yes), a call termination instruction is transmitted from the portable terminal 40 to the communication device 20 (S338 in FIG. 10). In the communication device 20, when the call end instruction is received (S240 in FIG. 8: Yes), the facsimile transmission process is not performed (S246 is not executed in FIG. 8). Therefore, it is possible to prevent a situation in which image data is facsimile-transmitted to the partner device 90 when the partner confirmed by the call is not the desired partner.

<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 communication device 20, the portable terminal 40, and the communication system 10 including the multifunction device 60 are taken as an example, and image data is formed when the multifunction device 60 reads an original with the scanner unit 70. It was. In addition, the communication system 10 may be configured to include the communication device 20, the mobile terminal 40, and a personal computer. In this case, the personal computer functions as an image forming apparatus in the same manner as the multifunction device 60 described above. In the personal computer, functions similar to those of the above-described multi-function device 60 are realized. The personal computer is installed with a computer program for processing similar to the above-described multifunction peripheral processing (see FIGS. 5 and 6). The installed computer program includes a driver for communicating with the communication device 20. As the image data, for example, data created by an application such as word processing software is processed by the driver and transmitted to the communication device 20 together with the first manual transmission request or the second manual transmission request (S118 in FIG. 5). And S120, and S108 and S110). Such facsimile transmission of image data using the personal computer and the communication device 20 is a transmission method corresponding to a transmission method called PC-FAX transmission. In the communication system 10 including a personal computer, the communication device 20 is a device including a printing unit 74 such as the multifunction device 60, and the multifunction device 60 executes communication device processing (see FIGS. 7 and 8). May be. The multi-function device 60 as an image forming apparatus for forming image data to be transmitted by facsimile may be a facsimile apparatus dedicated for facsimile communication. When there is one mobile terminal 40 included in the communication system 10, it is not necessary to identify the mobile terminal 40, and terminal information may be omitted.

  (2) In the above, when image data is transmitted by facsimile from the second communication unit 30 to the counterpart device 90 in the communication device 20, the following control is performed in the mobile terminal 40 and the communication device 20. It was. That is, in the mobile terminal 40, when the transmission start instruction is input (see S340 of FIG. 10: Yes), the CPU 42 ends the communication control started in S332 of the mobile terminal process (see FIGS. 9 and 10). (S344, see T27 in FIG. 4). Corresponding to this, in the communication device 20, the CPU 22 ends the relay between the portable terminal 40 and the counterpart device 90 in S246 of the communication device processing (see FIGS. 7 and 8). For example, when the communication system 10 is provided in an environment where a telephone call and facsimile transmission can be performed simultaneously using the same telephone number, in the portable terminal 40, the CPU 42 receives a transmission start instruction (see FIG. 10). Even if it is S340: Yes), the communication control started in S332 may be continued until a call end instruction is input. Correspondingly, the CPU 22 continues relaying in the communication device 20 as well. According to this, image data can be transmitted to the destination apparatus 90 by facsimile while talking to the user of the destination apparatus 90. In the environment as described above, the communication line 100 includes, for example, two lines of a public telephone line network and a next-generation network, and the communication system 10 and the destination apparatus 90 are the above-described two lines with the same telephone number. Constructed when supporting simultaneous communication. A telephone call is made via a public telephone line network, and facsimile transmission of image data is made via a next generation network. In order to support the above-described simultaneous communication on the two lines using the same telephone number, for example, it is necessary to make a predetermined contract with a telecommunications carrier that constructs such a communication line 100. There is also.
