The document is stored in the document storage unit 121. At this time, the control unit 11 stores identification information such as a file name for identifying the image data attached to the image data. When the image data input from the information processing apparatus connected to the communication apparatus 10 is a transmission target of FAX transmission, the control unit 11 stores the image data input from the information processing apparatus in the document storage. Stored in the unit 121.

<Step S13>
In step S <b> 13, the control unit 11 controls the communication IF 16 to establish communication with a communication apparatus that is a transmission destination of FAX transmission via the communication network 100. For example, the control unit 11 establishes communication with the transmission destination by dialing the FAX number of the transmission destination included in the transmission setting information.

<Step S14>
In step S <b> 14, the control unit 11 generates additional information D <b> 1 related to FAX transmission determined to start in step S <b> 11. The additional information D1 is, for example, image data attached to the header area or footer area of image data transmitted during FAX transmission. The additional information includes various types of information related to a transmission source of FAX transmission, contents of FAX transmission, and the like.

Address). The total page number D16 indicates the total number of pages of document data transmitted by FAX transmission. The page number D17 indicates the page number / total number of pages of each page of document data transmitted by FAX transmission. The content of the additional information D1 shown in FIG. 3 is merely an example.

<Step S15>
In step S <b> 15, the control unit 11 stores the additional information D <b> 1 generated in step S <b> 14 in the additional information storage unit 122 of the storage unit 12. Here, the step S15 corresponds to a second storage step, and the control unit 11 when executing the step S15 corresponds to a second storage processing means. At this time, the control unit 11 stores identification information such as a file name for identifying the additional information D1 attached to the additional information D1. The format of the additional information D1 stored in the additional information storage unit 122 is not limited to image data as long as the additional information D1 can be reproduced, and the format of each item included in the additional information D1. It may be text data indicating information.

<Step S16>
In step S16, the control unit 11 transmits the image data to be transmitted by FAX transmission via the communication network 100 together with the additional information D1 generated in step S14 when transmitting the image data. Send to the destination. The said control part 11 when performing the process which concerns here is an example of a transmission means.

  Specifically, the control unit 11 generates transmission image data in which the additional information D1 is arranged in a header area of the image data, and transmits the transmission image data to the transmission destination. In addition, the control unit 11 can sequentially transmit the additional information D1 and the image data without combining them. When the FAX transmission of the image data in step S16 ends, the control unit 11 shifts the process to step S17.

<Step S17>
In step S17, the control unit 11 stores correspondence information D2 indicating the correspondence between the image data and the additional information D1 in the correspondence information storage unit 123 of the storage unit 12, and returns the processing to step S11. Here, the step S17 corresponds to a third storage step, and the control unit 11 when executing the step S17 corresponds to a third storage processing means.

  In the example shown in FIG. 4, the correspondence information D2 includes identification information for identifying the F code D21, transmission time D22, image data D23, additional information D24, transmission source D25, and the like. The F code D21 is identification information for identifying a FAX transmission executed in the past. The item of the F code D21 indicates, for example, the name of the storage folder for the image data transmitted by the FAX transmission. In the present embodiment, the F code D21 is represented by the date and time of FAX transmission. For example, the F code “121119805” indicates a FAX transmission executed at 18:05 on November 19, 2012. The item of transmission time D22 is identification information of transmission time such as date and time when FAX transmission is executed. The item of the image data D23 is identification information such as a file name of the image data. The item of the additional information D24 is identification information such as a file name of the additional information D1. The item of the transmission destination D25 is identification information for identifying the FAX number (or name, address, etc.) of the FAX transmission destination. Note that the content of the correspondence information D2 shown in FIG. 4 is merely an example.

[FAX retransmission process]
Next, an example of the procedure of the FAX retransmission process will be described with reference to FIGS.

<Step S21>
In step S <b> 21, the control unit 11 determines whether there is a fax retransmission start request. Specifically, the control unit 11 starts the FAX retransmission when a user operation on the operation display unit 13 performs a retransmission start operation for starting setting of various retransmission setting information regarding FAX retransmission. Judge that there was a request. When the communication device 10 is connected to an information processing device such as a personal computer, the control unit 11 determines that a fax retransmission start request has been received when the retransmission request is received from the information processing device. To do.

  Here, when the control unit 11 determines that there is a request for starting FAX retransmission (Yes in S21), the control unit 11 shifts the processing to Step S22, and if there is no request for starting FAX retransmission (No in S21). Side), the determination in step S21 is repeated.

<Step S22>
In step S <b> 22, the control unit 11 causes the operation display unit 13 to display a selection screen G <b> 1 for selecting a past FAX transmission to be transmitted by FAX retransmission. On the selection screen G1, information on the history of FAX transmissions executed in the past by the communication device 10 is displayed. For example, information on some or all items of the correspondence information D2 is displayed on the selection screen G1. Further, it is conceivable that the control unit 11 displays the contents of the image data having the file name indicated in the item of the image data D23 on the selection screen G1 in a state that the user can see. For example, the selection screen G1 shown in FIG. 6 is a thumbnail display format in which the image data of the file name indicated in the item of the image data D23 is reduced and arranged together with the information of the F code D21 and the transmission time D22. It is the example of a display which employ | adopted.

  In addition, the control unit 11 receives an input of a transmission destination and a retransmission target period for the operation display unit 13, and one or a plurality of the document data transmitted to the transmission destination during the retransmission target period. And retransmitting the additional information. In this case, the user can easily select image data to be retransmitted simply by inputting the transmission destination and the retransmit target period. For example, the re-transmission target period is input by an operation for designating a start time and an end time for the operation display unit 13. In addition, it is also conceivable that the control unit 11 performs a search process for each item of the correspondence information D2 in accordance with a user operation of the operation display unit 13 and narrows down transmission targets for retransmission.

<Step S23>
In step S23, the control unit 11 determines whether or not a past FAX transmission to be transmitted for FAX retransmission is selected on the selection screen G1 displayed in step S22. The selection operation on the selection screen G1 is performed, for example, by a user's touch operation on the display surface of the operation display unit 13.

  When the control unit 11 determines that the transmission target for FAX retransmission has been selected (Yes in S23), the process proceeds to Step S24 until the transmission target for FAX retransmission is selected. (No side of S23), the process is made to wait in step S23.

<Step S24>
In step S24, the control unit 11 determines the image data and the additional information D1 corresponding to the past FAX transmission selected in step S23 based on the correspondence information D2 stored in the correspondence information storage unit 123. Are read from the document storage unit 121 and the additional information storage unit 122 of the storage unit 12. For example, when the correspondence information D2 shown in FIG. 4 is stored in the correspondence information storage unit 123, when the uppermost FAX transmission in which the item of the F code D21 is “121119805” is selected, the control The unit 11 reads the image data “1211191805-1.bmp” and the additional information D1 “1211198055-2.bmp” corresponding to the FAX transmission.

<Step S25>
In step S <b> 25, the control unit 11 controls the communication IF 16 to establish communication with a communication apparatus that is a destination of FAX retransmission via the communication network 100. Specifically, the control unit 11 reads the information of the transmission destination D25 corresponding to the past FAX transmission selected in the step S23 from the correspondence information D2, and dials the information to the transmission destination. Establish communication.

<Step S26>
In step S26, the control unit 11 transmits the image data and the additional information D1 read in step S24 to the transmission destination by FAX communication. Thus, in the communication device 10, the control unit 11 can retransmit the image data and the additional information D1 transmitted in the past by the FAX transmission process based on the correspondence information D2. . Here, the step S26 corresponds to a retransmission step, and the control unit 11 when executing the step S26 corresponds to a retransmission means. That is, in the FAX retransmission process, steps S14 to S15 in the FAX transmission process (see FIG. 2) are omitted. Accordingly, the control unit 11 performs FAX transmission using a combination of the image data and the additional information D1 transmitted in the past without newly generating additional information at the time of the current FAX retransmission. FIG. 7 shows an example of the image data and the additional information D1 retransmitted in step S26.

  Thus, the communication apparatus (for example, the communication apparatus 20) that is the transmission destination of the FAX retransmission by the communication apparatus 10 receives again the same information as the document data including the image data and the additional information D1 received in the past. Can do. Therefore, it is possible to obtain a printed matter based on the same image data as the image data that has been received once in the past in the communication apparatus that is the transmission destination of FAX retransmission. For example, a user of a communication device that is the destination of FAX retransmission can obtain the same printed material as the printed material even if the printed material received from the communication device 10 by FAX communication is lost. It is effective for continuity plan).

  The control unit 11 executes the generation process of the additional information D1 in the step S14 in the step S26, and is generated at the time of retransmission together with the image data and the additional information D1 corresponding to the past FAX transmission. The additional information D1 may be transmitted. Further, whether or not to transmit the additional information D1 corresponding to the retransmission can be selected according to a user operation in the initial setting process of the communication device 10 executed by the control unit 11 or the like. . Thus, the contents of the additional information D1 corresponding to the past FAX transmission can be confirmed, and the original image data received by the past FAX transmission and the image data received by the FAX retransmission can be identified. it can.

  In addition, as a technique for identifying original image data received by past FAX transmission and image data received by FAX retransmission, information previously set in the image data transmitted by the control unit 11 at the time of FAX retransmission is provided. It is conceivable to add a digital watermark including For example, the digital watermark may include information indicating that it is a retransmission, information indicating a retransmission time, and the like. As a result, it is possible to determine whether or not the printed material has been transmitted by FAX retransmission by reading the printed material with a reader capable of reading the digital watermark. In addition to the electronic watermark, it is also conceivable that the control unit 11 transmits a part of the image data with text information or image information indicating that it is retransmitted.

[Other Embodiments]
Hereinafter, other embodiments of the communication device 10 will be described.

[Polling reception function]
It is conceivable that the communication apparatus 10 has a polling reception function for executing FAX transmission in response to reception of a FAX transmission request from an external communication apparatus. The polling reception function is realized by the control unit 11 executing processing according to the communication program. The polling reception function is a function that is generally provided in a conventionally known facsimile apparatus, and therefore detailed description thereof is omitted here. In this case, in the communication apparatus 10, the control unit 11 can execute FAX retransmission in response to reception of a retransmission request from an external communication apparatus using the polling reception function.

  Here, an example of the procedure of the polling transmission process executed by the control unit 11 will be described with reference to FIG. In the following, the case where the communication device 10 receives the FAX transmission request from the communication device 20 will be described as an example.

<Step S31>
In step S <b> 31, the control unit 11 determines whether or not a FAX transmission request using the polling reception function is received by the communication IF 16. Here, when the control unit 11 determines that the FAX transmission request is received (Yes side of S31), the control unit 11 shifts the process to Step S32, and when the FAX transmission request is not received (No side of S31), The determination in step S31 is repeatedly executed.

<Step S32>
In step S <b> 32, the control unit 11 determines whether the FAX transmission request is a transmission history information transmission request regarding image data transmitted in the past by the communication device 10. Specifically, the control unit 11 indicates that an F code (an example of an identification code) included in the FAX transmission request indicates a transmission request for transmission history information regarding image data transmitted in the past by the communication device 10. Determine if it is a code. The F code is information for identifying image data transmitted in the past by the communication device 10, and is, for example, a folder name in the image storage unit 121 in which the image data is stored.

  Specifically, the F code indicating the transmission request for the transmission history information may be “0000000000000”. Here, if the said control part 11 judges that the said FAX transmission request is a transmission request of the said transmission history information (Yes side of S32), it will transfer a process to step S321. On the other hand, when determining that the FAX transmission request is not a transmission request for the transmission history information (No side in S32), the control unit 11 shifts the processing to step S33.

<Step S321>
In step S321, the control unit 11 transmits the transmission history information to the communication device 20 that is a transmission source of the retransmission request. In this way, the control unit 11 can transmit the transmission history information in response to a transmission request for the transmission history information. The said control part 11 when performing the said step S321 here is an example of a log | history transmission means.

  Here, the control unit 11 transmits only the transmission history information related to the image data in which the identification information of the transmission source stored in the correspondence information D2 matches the identification information of the transmission source of the retransmission request. Transmit to device 20. For example, the control unit 11 stores a CSI signal (identification information) of a transmission destination in the correspondence information D2 when executing FAX transmission, and then transmits a CIG signal transmitted from the transmission source of the FAX transmission request. Only information whose (identification information) matches the CSI signal is extracted from the correspondence information D2.

  For example, the transmission history information includes information such as the image data, F code, and transmission time transmitted in each FAX transmission performed in the past. As a result, the user of the communication device 20 refers to the transmission history information received from the communication device 10 and obtains information such as image data, F code, and transmission time transmitted in each fax transmission performed in the past. I can grasp it. In particular, the control unit 11 transmits the transmission history information including thumbnail images for displaying or printing each of the image data in a thumbnail format as in the selection screen G1 illustrated in FIG. It is possible.

<Step S33>
In step S <b> 33, the control unit 11 determines whether or not the FAX transmission request is a retransmission request for requesting retransmission of FAX transmission executed in the past by the communication apparatus 10. Specifically, when the F code included in the FAX transmission request corresponds to one of the F codes D21 stored in the correspondence information D2, the control unit 11 determines that the FAX transmission request is the retransmission. Judge as a request. Here, if the said control part 11 judges that the said FAX transmission request is not the said retransmission request (No side of S33), it will transfer a process to step S331. On the other hand, if the said control part 11 judges that the said FAX transmission request is the said retransmission request (Yes side of S33), it will transfer a process to step S34.

<Step S331>
In step S331, the control unit 11 performs normal polling transmission processing in which document data corresponding to the F code included in the FAX transmission request is read from the storage unit such as the storage unit 12 and transmitted to the communication device 20. Run.

<Step S34>
In step S34, the control unit 11 determines, based on the correspondence information D2 stored in the correspondence information storage unit 123, the image data corresponding to the F code included in the FAX transmission request received in step S31. The additional information D1 is read from the document storage unit 121 and the additional information storage unit 122 of the storage unit 12.

<Step S35>
In step S35, the control unit 11 transmits the image data and the additional information D1 read in step S34 to the communication device 20 by FAX communication. In this way, the control unit 11 can retransmit the image data and the additional information D1 corresponding to the F code when the F code is received by using the polling reception function. is there. Therefore, the communication device 20 can receive the image data and the additional information D1 that have been received in the past again.

  Therefore, in the communication device 10, in response to the FAX transmission request from the communication device 20, it is possible to retransmit the same information as the image data and the additional information D1 transmitted in the past. Accordingly, for example, the user of the communication device 10 does not need to perform a re-transmission operation, and the user of the communication device 20 can re-acquire document data at an arbitrary timing.

[Batch sending function]
Further, it is conceivable that the communication apparatus 10 has a collective transmission function for retransmitting a plurality of FAX transmissions executed in the past. The batch transmission function is realized by the control unit 11 executing a process according to the communication program.

  Here, consider a case where the communication device 10 has the polling reception function. In the polling reception function, a 20-digit F code can be used. Therefore, when the control unit 11 receives a 20-digit F code from the polling reception source, it receives the first 10-digit F code as a start code and the latter 10-digit F code as an end code. . The control unit 11 may determine the image data and the additional information D1 corresponding to one or more F codes included between the start code and the end code as retransmission targets. For example, when the correspondence information D2 is stored in the correspondence information storage unit 122 and the F code is “1211191805121211221359”, November 19, 2012 18:05 to November 22, 2012 13:00 Three fax transmissions (see FIG. 4) executed during 59 minutes are identified as retransmission targets. When the first half and the second half of the F code are the same as in the case where the F code is “12111918052111119805”, one FAX transmission executed at 18:05 on November 19, 2012 Are identified for retransmission. However, in this case as well, the control unit 11 specifies only F codes corresponding to FAX transmissions executed in the past with the F code transmission source as the transmission destination.

  Then, the controller 11 corresponds to one or more F codes included between the first 10 digits of the F code and the latter 10 digits of the F code in steps S34 to S35. The image data and the additional information D1 are read from the document storage unit 121 and the additional information storage unit 122 of the storage unit 12 and transmitted. Accordingly, a user of an external communication apparatus such as the communication apparatus 20 can specify a transmission target of the FAX retransmission process by specifying a start code and an end code by the F code, and can retransmit a plurality of FAX transmissions. You can request a batch of transmissions.

  The control unit 11 accepts an input of a 20-digit F code in response to a user operation on the operation display unit 13, and, as described above, one or more included in the first half and the second half of the F code. It is also conceivable to determine the F code as a retransmission target.

[Order sheet acceptance function]
Further, it is conceivable that the communication device 10 has an order sheet receiving function for performing FAX transmission according to the contents of the order sheet received from an external communication device by FAX communication. The order sheet receiving function is realized by the control unit 11 executing processing according to the communication program.

  Specifically, in step S321, the control unit 11 transmits the transmission history information in an order sheet format including a selection entry field M1 for instructing the presence / absence of retransmission for each past FAX transmission as shown in FIG. Send. The transmission history information shown in FIG. 9 is an example employing a mark sheet format in which the presence / absence of selection is indicated by the presence / absence of filling in the selection entry field M1. In this case, the user of the communication device 20 fills the selection entry field corresponding to the FAX transmission history that needs to be retransmitted in the order sheet on which the transmission history information in the order sheet format is printed. Then, the user of the communication device 20 causes the communication device 20 to transmit the order sheet filled with the selection entry field M1 to the communication device 10 by FAX transmission. On the other hand, in the communication device 10, when the control unit 11 receives the image data of the order sheet, the image selected by filling in the selection entry field M 1 by analyzing the image data. Identify data for retransmission. Then, the control unit 11 transmits the image data corresponding to the FAX transmission specified as the retransmission target and the additional information D1 to the transmission source of the order sheet. Thereby, the user of the communication device 20 can easily select the FAX transmission that needs to be retransmitted from the transmission history information and request the communication device 10 to request retransmission.
