However, the present invention is not limited to this, and the method of setting the format of data generated by each data generation unit is arbitrary.

  Next, an operation example of the image forming system 1 when the user inputs a request for print processing of the target file will be described with reference to FIG. FIG. 9 is a sequence diagram showing an operation example of the image forming system 1 in this case. First, the user inputs a print request for the target file (step S1). Specifically, as described above, the user inputs information corresponding to each item of “user name” and “password” displayed on the operation screen (see FIG. 5) of the operation panel display unit 17. . Then, in the “print” and “fax” fields displayed on the operation screen, a check is input in the “print” field and “print” is selected. Further, the user inputs specific information indicating the location of the target file (file to be printed) in the server device 20. Then, the user selects the “execute” icon displayed on the operation screen. In the present embodiment, a request for print processing of the target file is input by the above operation, but the method for inputting the request for print processing of the target file is not limited to this.

  When the operation reception unit 101 receives a print request for the target file, first, the image forming apparatus 10 transmits the input user name and password to the server apparatus 20 (step S2). The function of transmitting the input user name and password to the server device 20 is realized by an application installed in the image forming apparatus 10. The server device 20 that has received the user name and password transmitted from the image forming apparatus 10 performs an authentication process for determining whether or not the received user name and password match a preset user name and password. (Step S3). This authentication process is realized by an application installed in the server device 20. As a result of the authentication process, when it is determined that the input user name and password match the preset user name and password, the server device 20 confirms that the user has been authenticated (“Authentication OK”). Is present) to the image forming apparatus 10 (step S4). On the other hand, if it is determined that the input user name and password do not match the preset user name and password as a result of the authentication process, the process is stopped.

  When notified that the user has been authenticated, the print data acquisition unit 102 of the image forming apparatus 10 has identification information that can identify the requested printing process and specific information that indicates the location of the target file in the server apparatus 20. Is transmitted to the server device 20 (step S5). In this embodiment, the FTP command in this case includes command information for requesting file transfer (in this example, “RETR”), a path describing the path to the target file in the server device 20, and an extension indicating printing. It is configured by connecting parameters. In this example, a file extension for identifying the type of the target file is connected to the extended parameter indicating printing after the character string “/ print”. In the example of FIG. 9, since the file extension of the target file is “.pdf”, the extended parameter following the path is represented by “/print.pdf”.

  When the extended parameter analysis unit 201 of the server device 20 receives the FTP command from the image forming apparatus 10 (print data acquisition unit 102), the expansion parameter analysis unit 201 executes analysis processing described later (step S6). Next, the extension parameter analysis unit 201 executes an extension process described later based on the analysis result of the analysis process (step S7). As a result, the target file stored in the server device 20 is converted into data (print data) in a format printable by the image forming apparatus 10. The data transmission unit 206 transmits the print data obtained by the expansion process to the print data acquisition unit 102 as a response to the FTP command from the server device 20 (print data acquisition unit 102) (step S8). The print data acquisition unit 102 that has received the print data passes the received print data to the print instruction unit 103. Then, the print instruction unit 103 controls the printer unit 19 to execute printing based on the print data received from the print data acquisition unit 102 (step S9).

  Next, an operation example of the image forming system 1 when the user inputs a request for fax transmission processing of the target file will be described with reference to FIG. FIG. 10 is a sequence diagram illustrating an operation example of the image forming system 1 when the user inputs a request for fax transmission processing of a target file. First, the user inputs a request for fax transmission processing of the target file (step S10). Of the “Print” and “Fax” fields displayed on the operation screen, the only difference is that a check is entered in the “Fax” field. It is. Since the content of step S11-step S13 is the same as the content of step S2-step S4 of FIG. 9, detailed description is abbreviate | omitted.

  When it is notified after step S13 that the user has been authenticated, the fax transmission data acquisition unit 104 of the image forming apparatus 10 identifies identification information that can identify the requested fax transmission process, and a target in the server apparatus 20. An FTP command including specific information indicating the location of the file is transmitted to the server device 20 (step S14). The FTP command in this case is configured by connecting RETR, a path describing a route to the target file in the server device 20, and an extended parameter indicating fax transmission. In this example, the extension parameter indicating fax transmission is connected with the file extension of the target file after the character string “/ fax”. In the example of FIG. 10, since the file extension of the target file is “.tif”, the extension parameter following the path is represented by “/fax.tif”.

  When the extended parameter analysis unit 201 of the server device 20 receives the FTP command from the image forming device 10 (fax transmission data acquisition unit 104), the expansion parameter analysis unit 201 executes analysis processing described later (step S15). Next, the extension parameter analysis unit 201 executes an extension process described later based on the analysis result of the analysis process (step S16). As a result, the target file stored in the server device 20 is converted into data (fax transmission data) in a format that the image forming apparatus 10 can send by fax. The data transmission unit 206 transmits the fax transmission data obtained by the expansion process to the fax transmission data acquisition unit 104 as a response to the FTP command from the server device 20 (fax transmission data acquisition unit 104) (step S17). The fax transmission data acquisition unit 104 that has received the fax transmission data passes the received fax transmission data to the fax transmission instruction unit 105. Then, the fax transmission instruction unit 105 controls the fax unit 18 to execute a fax transmission process based on the fax transmission data received from the fax transmission data acquisition unit 104 (step S18).

  Next, an operation example of the image forming system 1 when the user inputs a request for preview processing of the target file will be described with reference to FIG. FIG. 11 is a sequence diagram illustrating an operation example of the image forming system 1 when the user inputs a request for preview processing of a target file. First, the user inputs a request for preview processing of the target file (step S20). As described above, in this embodiment, the user inputs a request for preview processing of a target file by selecting a file for which preview processing is to be executed from target file list data displayed on the operation screen. However, the present invention is not limited to this, and the method for inputting the request for preview processing of the target file is arbitrary. Since the content of step S21-step S23 is the same as the content of step S2-step S4 of FIG. 9, detailed description is abbreviate | omitted.

  When it is notified after step S23 that the user has been authenticated, the preview data acquisition unit 106 of the image forming apparatus 10 identifies identification information that can identify the requested preview process and the target file in the server apparatus 20. An FTP command including specific information indicating the location is transmitted to the server device 20 (step S24). The FTP command in this case is configured by connecting RETR, a path describing a path to a target file in the server device 20, and an extended parameter indicating a preview. In this example, the extension parameter indicating the preview is connected with the file extension of the target file after the character string “/ preview”. In the example of FIG. 11, since the file extension of the target file is “.jpg”, the extension parameter following the path is represented by “/preview.jpg”.

  When the extended parameter analysis unit 201 of the server device 20 receives the FTP command from the image forming apparatus 10 (preview data acquisition unit 106), the expansion parameter analysis unit 201 performs analysis processing described later (step S25). Next, the extended parameter analysis unit 201 executes an extension process described later based on the analysis result of the analysis process (step S26). As a result, the target file stored in the server device 20 is converted into data (preview data) in a format that can be previewed by the image forming apparatus 10. The data transmission unit 206 transmits the preview data obtained by the expansion process to the preview data acquisition unit 106 as a response to the FTP command from the server device 20 (preview data acquisition unit 106) (step S27). The preview data acquisition unit 106 that has received the preview data passes the received preview data to the data display unit 108. The data display unit 108 controls the operation panel display unit 17 (not shown) so as to display the acquired preview data (step S28).

  Next, referring to FIG. 12, an image when the user inputs a display request for target file list data indicating a list of files that can be printed by the image forming apparatus 10 among files belonging to the target folder. An operation example of the forming system 1 will be described. FIG. 12 is a sequence diagram illustrating an operation example of the image forming system 1 when a display request for target file list data indicating a list of files that can be printed by the image forming apparatus 10 among files belonging to the target folder is input. FIG. First, the user inputs a display request for target file list data indicating a list of files that can be printed by the image forming apparatus 10 among files belonging to the target folder (step S30). As described above, in this embodiment, the user inputs information corresponding to each item of “user name” and “password” displayed on the operation screen (see FIG. 5) of the operation panel display unit 17. . Then, a check is input in the “Print” column among the “Print” and “Fax” columns displayed on the operation screen. Next, the user inputs corresponding information in the “folder” item displayed on the operation screen. Then, the “list” icon displayed on the operation screen is selected. Through the above operation, a display request for target file list data indicating a list of files that can be printed by the image forming apparatus 10 among the files belonging to the target folder is input. Since the content of step S31-step S33 is the same as the content of step S2-step S4 of FIG. 9, detailed description is abbreviate | omitted.

  When it is notified after step S33 that the user has been authenticated, the target file list data acquisition unit 107 of the image forming apparatus 10 and the identification information that can identify the requested list display process, An FTP command including information indicating the location of the target folder is transmitted to the server device 20 (step S34). The FTP command in this case includes command information for requesting transfer of the data list (in this example, “NLST”), a path describing the path to the target folder in the server device 20, and an image assumed in the list display process. An extension parameter indicating that the processing (processing specified by the user) of the forming apparatus 10 is printing processing is connected. In this example, an extended parameter indicating that the process of the image forming apparatus 10 assumed in the list display process is a print process is represented by a character string “/ print”.

  When receiving the FTP command from the image forming apparatus 10 (target file list data acquisition unit 107), the extended parameter analysis unit 201 of the server device 20 executes an analysis process described later (step S35). Next, the extension parameter analysis unit 201 executes an extension process described later based on the analysis result of the analysis process (step S36). As a result, among the files belonging to the target folder, target file list data indicating a list of files that can be printed by the image forming apparatus 10 is generated in a format that can be displayed by the image forming apparatus 10. The data transmission unit 206 transmits the target file list data obtained by the expansion process to the target file list data acquisition unit 107 as a response to the FTP command from the server device 20 (target file list data acquisition unit 107) (step S37). ). The target file list data acquisition unit 107 that has received the target file list data passes the received target file list data to the data display unit 108. The data display unit 108 controls the operation panel display unit 17 (not shown) so as to display the acquired target file list data (step S38).

  The operation example of the image forming system 1 when the user inputs a display request for target file list data indicating a list of files that can be subjected to the fax transmission process among the files belonging to the target folder is almost the same. It is. In this case, when inputting a display request for the target file list data, the user inputs a check in the “FAX” field displayed on the operation screen. When notified that the user has been authenticated, the target file list data acquisition unit 107 of the image forming apparatus 10 performs NLST, a path describing the path to the target folder in the server apparatus 20, and a list display process. Are connected to an extension parameter indicating that the processing of the image forming apparatus 10 assumed in FIG. In this example, the extended parameter indicating that the process of the image forming apparatus 10 assumed in the list display process is a fax transmission process is represented by a character string “/ fax”.

  In the present embodiment, the above-described command information and extended parameters can be regarded as identification information that can identify the process for which the operation reception unit 101 has received a request, but is not limited thereto. For example, a predetermined flag or character string may be set as identification information that can identify the process for which the operation reception unit 101 has received a request. In short, the identification information only needs to be information that can identify the process for which the operation reception unit 101 has received the request, and the configuration thereof is arbitrary.

  FIG. 13 is a flowchart illustrating an example of a processing operation performed by the image forming apparatus 10. As illustrated in FIG. 13, when the operation reception unit 101 receives a request for any of printing processing, fax transmission processing, preview processing, and list display processing (result of step S101: YES), each data acquisition is performed. The units (the print data acquisition unit 102, the fax transmission data acquisition unit 104, the preview data acquisition unit 106, and the target file list data acquisition unit 107) transmit an FTP command to the server device 20 (step S102). And when each data acquisition part receives the process data used for the process which received the request | requirement in the operation reception part 101 as a response with respect to an FTP command (the result of step S103: YES), based on the process data The requested processing is executed (step S104).

  For example, the processing data when a request for the print processing of the target file is received is print data, and the print instruction unit 103 (processing unit) executes the requested print processing based on the print data. The processing data when a request for fax transmission processing of the target file is received is fax transmission data, and the fax transmission instruction unit 105 (processing unit) performs the requested fax transmission processing based on the fax transmission data. Run. The processing data when a request for preview processing of the target file is received is preview data, and the data display unit 108 (processing unit) executes the requested preview processing based on the preview data. Further, the processing data when the request for the list display process is received is the target file list data, and the data display unit 108 (processing unit) executes the requested list display process based on the target file list data. .

  FIG. 14 is a flowchart illustrating an example of a processing operation performed by the server device 20. As shown in FIG. 14, when the FTP command from the image forming apparatus 10 is received (step S110), the extended parameter analysis unit 201 has the command information included in the received FTP command “RETR” or “NLST”. Whether or not (step S112). If it is determined that the command information included in the received FTP command is “RETR” or “NLST” (result of step S112: YES), the process proceeds to step S112. On the other hand, if it is determined that the command information included in the received FTP command is not “RETR” or “NLST”, the process proceeds to step S118 and normal FTP processing is executed.

  In step S112, the extended parameter analysis unit 201 determines whether the information subsequent to the command information (RETR or NLST) is information that can specify specific data in the server device 20. For example, it is assumed that the operation receiving unit 101 receives a print processing request for a target file (file extension is “.pdf”) specified by a path “/ server / A folder / B file.doc”. To do. In this case, the information following the RETR in the FTP command transmitted from the image forming apparatus 10 is the extension parameter “/print.pdf” at the end of the path “/ server / A folder / B file.doc” of the target file. Is connected to "/ server / A folder / B file.doc / print.pdf". If it is determined that the information “/ server / A folder / B file.doc / print.pdf” following RETR is information that can specify specific data (file or folder) in the server device 20 In step S118, normal FTP processing is performed. On the other hand, when it is determined that the information “/ server / A folder / B file.doc / print.pdf” following RETR is not information that can specify specific data (file or folder) in the server device 20 The process proceeds to step S113.

  In step S113, the extended parameter analysis unit 201 determines whether or not the end of the information following the command information in the received FTP command indicates a preset extended parameter. If it is determined that the end of the information following the command information is not an extended parameter, the process proceeds to step S117, and an error indicating that the received FTP command cannot be processed is notified. On the other hand, if it is determined that the end of the information following the command information is an extended parameter and the command information indicates “RETR”, the process proceeds to step S114. If it is determined that the end of the information following the command information is an extended parameter and the command information indicates “NLST”, the process proceeds to step S116.

  In step S <b> 114, the extended parameter analysis unit 201 determines whether there is a file path that is the same as the path one layer above the extended parameter at the end. More specifically, in the extended parameter analysis unit 201, the part of the FTP command excluding the extended parameter at the end from the information following the RETR is a file path describing the path to the specific file in the server device 20. Determine whether or not. In the above example, the extended parameter analysis unit 201 removes the extended parameter “/print.pdf” from the information “/ server / A folder / B file.doc / print.pdf” following the RETR “/ server / It is determined whether or not “A folder / B file.doc” is a file path describing a route to a specific file in the server device 20. If it is determined that the same file path as the path one layer higher than the extended parameter exists (result of step S114: YES), the process proceeds to step S115. If it is determined that the same file path as the path one layer higher than the extended parameter does not exist (result of step S114: NO), the process proceeds to step S117 and an error is notified.

  In step S116, the extended parameter analysis unit 201 determines whether there is a folder path that is the same as the path one layer higher than the last extended parameter. More specifically, in the extended parameter analysis unit 201, the portion of the FTP command excluding the extended parameter at the end from the information following the NLST is a folder path describing the route to a specific folder in the server device 20. Determine whether or not. In the above example, the extended parameter analysis unit 201 determines that the part “/ server / A folder” obtained by removing the extended parameter “/ print” from the information “/ server / A folder / print” following the NLST is stored in the server device 20. It is determined whether or not the folder path describes the path to the specific folder. If it is determined that the same folder path as the path one layer higher than the extended parameter exists (result of step S116: YES), the process proceeds to step S115. If it is determined that the same folder path as the path one layer higher than the extended parameter does not exist (result of step S116: NO), the process proceeds to step S117 and an error is notified.

  In step S115, an expansion process is executed. FIG. 15 is a flowchart illustrating an example of the extension process executed by the server device 20. When the command information included in the FTP command received by the extended parameter analysis unit 201 is RETR (result of step S120: YES), the process proceeds to step S121. In step S121, the extended parameter analysis unit 201 analyzes the extended parameter at the end of the FTP command. Then, based on the analysis result, the operation reception unit 101 receives a request for each data generation unit (here, the print data generation unit 202, the fax transmission data generation unit 203, and the preview data generation unit 204). The generation of processing data to be used is instructed (step S122). For example, if the extension parameter is “/print.pdf” as a result of the analysis by the extension parameter analysis unit 201, the extension parameter analysis unit 201 sends a file path one layer higher than the extension parameter to the print data generation unit 202. The image forming apparatus 10 is instructed to convert the target file specified in (1) into data in a format that allows the image forming apparatus 10 to execute print processing. That is, the extended parameter analysis unit 201 instructs the print data generation unit 202 to generate print data of the target file.

  Next, the data transmission unit 206 transmits the data generated in step S122 to the client (image forming apparatus 10 in this example) (step S123). Each data generation unit deletes the generated data (step S124).

  On the other hand, when the command information included in the FTP command received by the extended parameter analysis unit 201 is not RETR (result of step S120: NO), it is determined that the command information included in the FTP command is NLST, and the process proceeds to step S125. Migrate to In step S125, the extended parameter analysis unit 201 analyzes the extended parameter at the end of the FTP command. Based on the analysis result, the target file list data generation unit 205 is instructed to generate target file list data (step S126). For example, as a result of analysis by the extended parameter analysis unit 201, when the extended parameter is “/ print” indicating that the processing of the image forming apparatus 10 assumed in the list display processing is print processing, the extended parameter analysis unit 201 The target file list data generation unit 205 shows a list of files that can be printed by the image forming apparatus 10 among the files belonging to the target folder specified by the folder path one level higher than the extended parameter. Instructs generation of target file list data.

  Next, the data transmission unit 206 transmits the target file list data generated in step S126 to the client (image forming apparatus 10 in this example) (step S127). The above is the contents of the extension process. Further, in the present embodiment, Step S110 to Step S114, Step S116, Step S117 in FIG. 14 and Step S121 and Step S125 in FIG. 15 can be regarded as analysis processing executed by the extended parameter analysis unit 201.

  As described above, in the present exemplary embodiment, when a request for any process is input to the image forming apparatus 10 that can execute a plurality of processes, the image forming apparatus 10 performs the requested process. An FTP command including identifiable identification information is transmitted to the server device 20. Then, the server device 20 generates processing data (for example, print data, fax transmission data, preview data, target file list data, etc.) used for the requested processing based on the identification information included in the FTP command. The image is transferred to the image forming apparatus 10. Therefore, the image forming apparatus 10 can execute a plurality of processes without having a function of generating processing data used for the requested process. That is, according to the present exemplary embodiment, the configuration of the image forming apparatus 10 capable of executing a plurality of processes can be simplified and the characteristics can be exhibited.

  Note that various programs executed by the image forming apparatus 10 or the server apparatus 20 according to the above-described embodiments are files in an installable format or an executable format, such as a CD-ROM, a flexible disk (FD), a CD-R, and a DVD. (Digital Versatile Disk), USB (Universal Serial Bus), etc. may be recorded and provided on a computer-readable recording medium, or may be provided or distributed via a network such as the Internet. May be.

(Modification)
As mentioned above, although embodiment which concerns on this invention was described, this invention is not limited to the above-mentioned embodiment, A various deformation | transformation is possible within the range which does not deviate from the summary of this invention. Modified examples will be described below. The following modifications can be arbitrarily combined.

(1) Modification 1
For example, a method for inputting a request for each process executable by the image forming apparatus 10 is arbitrary. For example, when inputting a print request for a target file, a user first inputs a display request for a target file list indicating a list of files that can be printed by the image forming apparatus 10 among files stored in the server device 20. Then, after executing the list display processing, any file included in the displayed target file list can be selected, and a print request for the selected file can be input. A similar input method can also be adopted when inputting a fax transmission request for a target file.

(2) Modification 2
Further, in the above-described embodiment, the case where the image forming apparatus 10 inputs a display request for target file list data indicating a list of files that can execute a specified process among files belonging to a specific folder is exemplified. However, for example, without specifying a folder, it is possible to input a display request for target file list data indicating a list of files that can execute the specified processing among the files held in the server device 20. . For example, it is assumed that the image forming apparatus 10 inputs a display request for target file list data indicating a list of files that can be printed out of files held in the server apparatus 20.

  In this case, the user first inputs corresponding information to each item of “user name” and “password” displayed on the operation screen. Then, a check is input in the “Print” column among the “Print” and “Fax” columns displayed on the operation screen. In this case, the user does not need to input information indicating the location of the target folder in the server device 20, and selects the “list” icon displayed on the operation screen. Through the above operation, a display request for target file list data indicating a list of files that can be printed by the image forming apparatus 10 among the files held in the server apparatus 20 is input. In this case, the FTP command transmitted to the server device 20 does not include a path describing a route to a specific folder in the server device 20. When the extended parameter analysis unit 201 analyzes that the extended parameter at the end of the received FTP command is “/ print” indicating that the process of the image forming apparatus 10 assumed in the list display process is a print process, The print data generation unit 202 is instructed to generate target file list data indicating a list of files that the image forming apparatus 10 can execute print processing out of all files stored in the server device 20.

(3) Modification 3
In the above-described embodiment, the image forming apparatus has been described as an example of the information processing apparatus connected to the server apparatus 20, but the present invention is not limited to this. In short, the information processing apparatus connected to the server device 20 can execute a plurality of processes, and the identification information that identifies the reception unit that receives a request for any of the processes and the process that has received the request at the reception unit Are transmitted to the server device 20, a receiving unit that receives processing data used for the requested processing from the server device 20, and a processing unit that executes the requested processing based on the processing data. An information processing apparatus including the above can be employed, and the type thereof is arbitrary.
