  Conventionally, an error that may occur when facsimile data received by a facsimile apparatus is transmitted to another apparatus has not been sufficiently considered. For this reason, there was a possibility that communication wasted between the facsimile apparatus and another apparatus due to the occurrence of an error.

  An object of the present invention is to reduce waste of communication that may occur between a facsimile machine and a storage server.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following application examples.

Application Example 1 A facsimile apparatus that receives facsimile data representing an original image, a transmission unit that transmits image data representing the original image to a storage server that is a storage destination of the image data, The receiving unit receives the first facsimile data, receives the second facsimile data after receiving the first facsimile data, and the transmitting unit receives the first facsimile data to the storage server. If the transmission of the first image data corresponding to the facsimile data is attempted and the transmission result of the first image data to the storage server indicates a first type of error, the second image data to the storage server is displayed. If transmission of the second image data corresponding to the facsimile data of the first image data is not attempted and the transmission result of the first image data to the storage server indicates a second type of error, the storage is not performed. It attempts to send the second image data to the server, a facsimile device.

  According to the above configuration, when the transmission result of the first image data indicates the first type of error, the transmission unit does not attempt to transmit the second image data, so the first type of error is, for example, In the case of an error that is difficult to resolve unless there is a user action, wasteful communication that may occur between the facsimile apparatus and the storage server can be reduced.

Application Example 2 As a control server, a reception notification receiving unit that receives a reception notification transmitted from a facsimile apparatus in response to reception of facsimile data representing an original image, and the facsimile apparatus in response to the reception notification An operation command unit that transmits an operation command for controlling transmission of the image data to a storage server that is a storage destination of image data representing the original image, and the storage server according to the operation command from the facsimile apparatus A transmission result receiving unit for receiving information on the transmission result of the image data to the reception notification receiving unit, wherein the reception notification of the first facsimile data and the first facsimile data are received. Receiving the second facsimile data received later, and the operation command unit sends the facsimile command to the facsimile server. When the operation command for attempting to transmit the first image data corresponding to the first facsimile data is transmitted, and the transmission result of the first image data to the storage server indicates a first type error. Does not transmit the operation command for attempting to transmit the second image data to the storage server, and the transmission result of the first image data to the storage server indicates a second type of error. A control server that transmits the operation command that causes transmission of the second image data to the storage server.

  According to the above configuration, when the transmission result of the first image data indicates the first type of error, the facsimile apparatus is not allowed to try to transmit the second image data, and therefore, between the facsimile apparatus and the storage server. Communication waste that may occur can be reduced.

  The present invention can be realized in various forms other than the above-described apparatus. For example, a system including a facsimile apparatus and a control server, a control method for a facsimile apparatus, and the above-described apparatus, system, or method are realized. And a computer program for recording the computer program.

A. Example:
A-1: Configuration of System 1000 Next, an embodiment of the present invention will be described based on examples. FIG. 1 is a block diagram showing a configuration of a system 1000 as an embodiment of the present invention. The system 1000 includes a multifunction peripheral 100, a control server 200, and a plurality of storage servers 310 to 330. These apparatuses 100, 200, 310 to 330 are configured separately from each other. The multifunction device 100 is connected to a LAN (Local Area Network) 70. The LAN 70 is connected to the Internet 80. The control server 200 and the storage servers 310 to 330 are connected to the Internet 80. As a result, the multifunction peripheral 100 and the servers 200, 310 to 330 can communicate with each other via the LAN 70 and the Internet 80.

  The storage servers 310 to 330 are servers that provide a storage service that can store image data. Each storage server is, for example, a cloud server including a plurality of computers and a plurality of storage devices connected to be communicable with each other. The storage service includes, for example, a storage service that stores data transmitted from a client (multifunction device 100 or personal computer (not shown)), and a social network service that stores and discloses data transmitted from the client. Specifically, the preservation service includes "Evernote (registered trademark)", "Google (registered trademark) Drive", "PICASA (registered trademark)", "SkyDrive (registered trademark)", "Dropbox (registered trademark)" It includes known services such as “Box.net”, “Flickr (registered trademark)”, and “Facebook (registered trademark)”.

  The names of the storage services provided by the storage servers 310, 320, and 330 are “SN1”, “SN2”, and “SN3”, respectively. The operators that operate the storage services SN1 to SN3 provided by the storage servers 310 to 330 are different from each other. The operators of the storage services SN1 to SN3 are also different from the vendor of the multifunction peripheral 100. URLs (Uniform Resource Locators) to be accessed to use the storage services SN1 to SN3 are different from each other. The URLs to be accessed to use the storage services SN1 to SN3 are “URL1”, “URL2”, and “URL3”, respectively. “URL1”, “URL2”, and “URL3” can be said to be location information indicating the location on the Internet 80 of the storage servers 310 to 330 that provide the storage services SN1 to SN3, respectively.

  The multifunction device 100 includes a CPU 110 as a controller of the multifunction device 100, a nonvolatile storage device 120 such as a hard disk drive or an EEPROM, a volatile storage device 130 such as a RAM, and a predetermined method (for example, a laser method or an inkjet method). ), A printer unit 140 that prints an image, a scanner unit 150 that acquires scan data by optically reading an object (for example, a paper document), an operation unit 160 such as a touch panel and buttons, and a touch panel. A display unit 170 such as a liquid crystal panel, a network IF 180, and a telephone line IF 190 are provided.

  The network IF 180 is an interface compliant with, for example, the Ethernet (registered trademark) standard, and is used to connect to the LAN 70. The telephone line IF 190 is, for example, an interface of a two-wire or four-wire analog telephone line, and is used to connect to an analog telephone line network 90, that is, a PSTN (Public Switched Telephone Network).

  The nonvolatile storage device 120 stores a computer program PG1, FAX general setting information FG, service information list SL, and FAX reception list FL. The volatile storage device 130 is provided with a buffer area 131 for temporarily storing various intermediate data generated when the CPU 110 performs processing.

  The program PG1 is provided in a form stored in advance in the nonvolatile storage device 120 at the time of shipment of the multifunction peripheral 100. The computer program PG1 may be provided in a form downloaded from a server connected to the multifunction peripheral 100 via the Internet 80, or may be provided in a form stored in a CD-ROM, DVD-ROM, or the like.

  The CPU 110 functions as a control unit of the multifunction peripheral 100 by executing the computer program PG1. Specifically, the CPU 110 controls the printer unit 140 and the scanner unit 150 to execute printing and scanning. The CPU 110 implements a facsimile function. That is, the CPU 110 can execute a function of converting image data (for example, scan data generated by the scanner unit 150) into facsimile data according to a standard such as FAXG3 and transmitting the converted data to an external device via the telephone line IF 190. The CPU 110 can execute a function of receiving facsimile data from an external device via the telephone line IF 190 and outputting an image represented by the facsimile data (hereinafter also referred to as a FAX image). The output of the FAX image includes, for example, printing using the printer unit 140 and displaying on the display unit 170.

  Further, the CPU 110 can realize a server cooperation function by executing the computer program PG1. Specifically, the CPU 110 operates according to a command transmitted from the control server 200 by accessing the control server 200. Thus, the CPU 110 can realize a server cooperation function that is a function that cannot be realized by itself. The server cooperation function will be described later.

  FIG. 2 is a diagram illustrating an example of various types of information. The FAX general setting information FG, the service information list SL, and the FAX reception list FL in FIGS. 2A to 2C are stored in the nonvolatile storage device 120 of the multifunction peripheral 100 as described above. The service usage information SA in FIG. 2D and the error information EI in FIG. 2E are stored in the nonvolatile storage device 220 of the control server 200 as will be described later. The FAX general setting information FG in FIG. 2A is information indicating settings relating to the facsimile function. The FAX general setting information FG includes setting information indicating whether the fax to cloud function is enabled (ON) or disabled (OFF), and whether the display only mode is enabled (ON) or disabled (OFF). Including setting information. The Fax to Cloud function is one of the server linkage functions described above. As will be described in detail later, the Fax to Cloud function transmits (uploads) image data representing a FAX image represented by facsimile data (hereinafter also referred to as FAX image data) to the storage server in response to reception of the facsimile data. It is a function to do. When the display only mode is valid, when the facsimile data is received, the CPU 110 displays an image represented by the facsimile data on the display unit 170, and prints the image unless the user gives a print instruction. do not do. When the display only mode is invalid, the CPU 110 automatically prints an image represented by the facsimile data when the facsimile data is received. The initial value of the setting information indicating whether the display only mode is valid or invalid is a value indicating invalidity.

  The service information list SL in FIG. 2B includes account information AD and fax to cloud setting information FC. The account information AD is registered for each account of the storage services SN1 to SN3 used in the server cooperation function. The account information AD includes a storage service name, a user name, and a token. The user name (for example, “Alice”) is a character string registered by the user. The token (for example, “TK1”) is authentication information for accessing a storage server (for example, the storage server 310) that provides a storage service. The Fax to Cloud setting information FC includes FAX image transmission settings and format information. The FAX image transmission setting and the format information are registered for each account. The FAX image transmission setting indicates whether or not FAX image data is transmitted to a corresponding storage server using a corresponding token when the Fax to Cloud function is valid. When the FAX image transmission setting is “ON”, the FAX image data is transmitted to the corresponding storage server using the corresponding token, and when the FAX image transmission setting is “OFF”, the corresponding token is Indicates that FAX image data is not transmitted to the corresponding storage server. The format information indicates the format of the image file used when FAX image data is transmitted to the storage server by the Fax to Cloud function. Formats used in this embodiment include, for example, JPEG (Joint Photographic Experts Group) format, PDF (Portable Document Format), and TIFF (Tagged Image File Format).

  The Fax to Cloud setting information FC further includes information indicating whether backup printing is valid or invalid. When the backup printing is valid, the FAX image is automatically printed in addition to the transmission of the FAX image data to the storage server in the Fax to Cloud function. When backup printing is invalid, the FAX to Cloud function only transmits FAX image data to the storage server and does not print the FAX image.

  The service information list SL is not text data but binary data. In order to interpret each piece of information in the service information list SL, interpretation information IP that associates the value of each piece of information in the service information list SL and the meaning of the value (for example, a format name such as JPEG or PDF) is required. It is. The multi-function device 100 does not have the interpretation information IP. For this reason, the CPU 110 of the multifunction peripheral 100 can transmit the service information list SL to the control server 200, but cannot directly use individual information in the service information list SL.

  The FAX reception list FL in FIG. 2C includes one or more entries EN generated for each received facsimile data. Each entry EN indicates a FAX ID that is an identifier (for example, “001”) of facsimile data, information (for example, “TM1”) that indicates the date and time when the facsimile data was received, and a facsimile number that is the transmission source of the facsimile data. Information (for example, “FN1”). Each entry EN is generated, for example, when corresponding facsimile data is received, and is deleted from the FAX reception list FL when the facsimile data is deleted from the nonvolatile storage device 120.

  The control server 200 (FIG. 1) is a server provided by the vendor of the multifunction device 100. The control server 200 includes a CPU 210 as a controller of the control server 200, a nonvolatile storage device 220 such as a hard disk drive, a volatile storage device 230 such as a RAM, and a network IF 280 for connecting to the Internet 80. Yes.

  The nonvolatile storage device 220 stores a computer program PG2, service usage information SA in FIG. 2D, interpretation information IP, and error information EI in FIG. The volatile storage device 230 is provided with a buffer area 231 for temporarily storing various intermediate data generated when the CPU 210 performs processing. The computer program PG2, service usage information SA, and interpretation information IP may be provided in a form uploaded from a vendor computer connected via the Internet 80, and stored in a CD-ROM, DVD-ROM, or the like. May be provided at.

  The CPU 210 executes the computer program PG2 to cause the multifunction peripheral 100 to realize the server cooperation function described above. Specifically, the CPU 210 controls the multifunction peripheral 100 by transmitting various operation commands to the multifunction peripheral 100 in response to access from the multifunction peripheral 100. As a result, the CPU 210 can cause the multifunction peripheral 100 to realize a server cooperation function.

  The service usage information SA in FIG. 2D is information regarding the storage services SN1 to SN3 realized by the storage servers 310 to 330. The service usage information SA includes a service name (for example, SN1), possible format information (for example, JPEG), a transmission method (for example, MT1), and an upload destination URL (for example, URL1). The service usage information SA is created based on an API (Application Programming Interface) published by each storage service provider. These APIs are rules necessary for calling and using a storage service function from an external device, for example, a procedure that defines an access procedure (protocol) and a data format to be used when executing the procedure. is there. That is, referring to the public API, the URL to be accessed to use the storage service, the parameter to be transmitted, the data format for transmitting the parameter and image data to be stored, etc. can be understood.

  The possible format information indicates the format of image data that can be stored by the storage service. For example, a dedicated storage service for image data may support only a format for image data such as JPEG. A storage service that stores arbitrary data may support image data of an arbitrary format. The transmission method indicates a method of transmitting image data to the storage server, for example, a transmission procedure and a parameter to be transmitted. The upload destination URL is a URL indicating the destination of image data or parameters.

  In the service information list SL described above, the token is associated with the storage services SN1 to SN3, and in the service usage information SA, the upload destination URL is associated with the storage services SN1 to SN3. Therefore, it is understood that the token and the upload destination URL are associated with each other by the service information list SL and the service usage information SA.

  As described above, the interpretation information IP is information for interpreting the service information list SL. Since the control server 200 has the interpretation information IP, it can interpret the service information list SL that the multi-function device 100 has.

  In the error information EI of FIG. 2E, the latest result of the client sending (uploading) the FAX image data to the storage server in the Fax to Cloud processing described later for each client (for example, the multifunction peripheral 100) is shown. Information to be recorded is recorded. Information indicating the transmission result (upload result) is recorded in association with the client ID. As the client ID, for example, a client unique ID such as a client MAC address or a client product number (serial number) is used. The information indicating the transmission result indicates that there was no error (normal) when the most recent upload was successful, and indicates the error that caused the failure when the most recent upload failed. Information. Errors that cause upload failure include a first type error and a second type error.

  The first type of error includes an authentication error, a storage capacity upper limit violation error, and a write authority violation error. The authentication error is an error that the token cannot be determined to be authentic and the account corresponding to the token cannot be authenticated. The storage capacity upper limit violation error is an error in which the usable storage capacity in the storage server assigned to the account corresponding to the token is insufficient. The write authority violation error is an error in which there is no write authority for the storage area of the write destination in the storage server (for example, the upload destination URL or the write destination folder specified by the folder ID). The first type of error is difficult to resolve unless the user performs some kind of action, for example, reacquisition of tokens, deletion of data stored in the storage server, and acquisition of write authority. That is, the first type of error can be said to be an error that requires a user's action to be resolved. The first type of error is not limited to the above three errors, but preferably includes at least one of the above three errors.

  The second type of error includes a communication failure error and a service stop error. The communication failure error is an error caused by a communication failure between the multifunction peripheral 100 and the target storage server (for example, an error in which the entire image file to be received due to timeout cannot be received). The service stop error is an error in which the image file cannot be saved because the target storage server temporarily stops the service. The second type of error can be automatically resolved by reducing the network traffic or restarting the storage server service. In other words, the second type of error can be said to be an error that can be resolved without any user action. The second type of error is not limited to the above two errors, but preferably includes at least one of the above two errors.

  The CPU 210 of the control server 200 transmits a series of operation commands to the multifunction device 100 using the service usage information SA, the error information EI, and the service information list SL acquired from the multifunction device 100. The CPU 110 of the multifunction peripheral 100 receives a series of operation instructions and operates according to the series of operation instructions, thereby acquiring necessary instructions from the user and transmitting (uploading) FAX image data to a storage server. Fax to Cloud function can be realized. As a result, it becomes easy to deal with a new storage service or to change the specifications of an existing storage service. For example, by updating the service usage information SA and the program PG2 of the control server 200 based on the API of the new storage service or the API updated in accordance with the specification change of the storage service, a new storage service or existing It is possible to cope with changes in specifications of storage services. In other words, if the vendor executes an update process for the control server 200, the user can perform a new storage service or specification change via the multifunction device 100 without updating the computer program PG1 of the multifunction device 100. Fax image data can be stored using a later storage service.

A-2: Operation of the system 1000 A-2-1. Preparation Before a user uses the multifunction machine 100 to use the Fax to Cloud function, the user registers the account information AD in the service information list SL of the multifunction machine 100 in a PC (Personal Computer) (not shown): Execute the process. The PC accesses the storage server 310 according to the user's operation, and acquires the user account of the storage service SN1 provided by the storage server 310. When the account is acquired, the user ID and password for using the storage service SN1 are registered in the storage server 310.

  Next, the PC accesses the control server 200 according to the user's operation, and acquires a specific URL for accessing the token distribution service provided by the storage server 310 from the control server 200. The PC designates a specific URL, accesses the storage server 310, and transmits the registered user ID and password to the storage server 310 in accordance with a user operation.

  The storage server 310 specifies a user account corresponding to the user ID and password transmitted from the PC. The storage server 310 generates a token corresponding to the identified user account and transmits it to the control server 200. The storage server 310 recognizes in advance that the generated token should be transmitted to the control server 200 when the registered user ID and password are transmitted through access designating a specific URL.

  When receiving the token, the control server 200 generates a temporary ID associated with the token and transmits the temporary ID to the PC. The PC displays the received temporary ID.

  The user operates the operation unit 160 of the multifunction device 100 to display the name of the storage service SN1 (“SN1”), the user name (for example, “Alice”), and the temporary ID displayed on the PC. Enter 100. The multi-function device 100 that has received the input of the information transmits the input temporary ID to the control server 200. The control server 200 transmits a token (for example, “TK1”) associated with the temporary ID to the multi-function device 100. The control server 200 deletes the token that has been transmitted to the multifunction peripheral 100 from the nonvolatile storage device 220 of the server 200.

  The MFP 100 receives a set of account information AD including the received token (eg, “TK1”), the name of the storage service SN1 (“SN1”), and the user name (eg, “Alice”). Register in the service information list SL. Thus, for each account of the storage service, one set of account information AD is registered in the service information list SL.

  The example in which the account information AD of the storage service SN1 is registered in the service information list SL has been described above, but the same processing is performed on the other storage services SN2 and SN3. It can be registered in the information list SL. In the service information list SL of FIG. 2, the account information AD of one user is registered for the storage service SN1, and the account information AD of two users is registered for the storage service SN2.

A-2-2. Setting Processing The operation of the system 1000 will be described focusing on the processing for realizing the above-described server cooperation function, particularly the Fax to Cloud function. 3 and 4 are flowcharts of the setting process of the fax to cloud function. This setting process is started when the multifunction device 100 receives an instruction to start using the server cooperation function from the user. Note that the setting process and the Fax to Cloud process, which will be described later, include communication between the multifunction peripheral 100 and the control server 200 as shown in FIGS. 3, 4, 8, and 9. These communications are executed using HTTP (Hypertext Transfer Protocol). That is, in the setting process, data (for example, various notifications, information, and requests) transmitted from the MFP 100 to the control server 200 is transmitted as an HTTP request. The header of the HTTP request includes a URL indicating the resource to be processed, and the HTTP request is transmitted according to the URL. That is, when the URL indicates a resource in the control server 200, an HTTP request including the URL is transmitted to the control server 200. Hereinafter, the URL included in the header of the HTTP request is referred to as a destination URL. Further, data (for example, various operation commands) transmitted from the control server 200 to the multifunction peripheral 100 is transmitted as an HTTP response to the HTTP request received immediately before.

  When the setting process is started, in S <b> 1, the CPU 110 of the multifunction peripheral 100 transmits a request for the first command to the control server 200. In the first command request, a predetermined URL is used as the destination URL.

  When the control server 200 receives the request for the first command, the CPU 210 transmits a display command for the function selection screen SC1 to the multi-function device 100 (S2). The display command is a kind of operation command transmitted from the control server 200 to the multifunction device 100.

  FIG. 5 is a diagram illustrating an example of an operation command. The display command in FIG. 5A is a command for causing the multifunction peripheral 100 to display a screen to be displayed. The display command includes information indicating that it is a display command, display screen data representing a screen to be displayed, and a next designated URL. The display screen data is described using, for example, XML (Extensible Markup Language). The next designated URL is used as a destination URL in an HTTP request to be transmitted from the MFP 100 next time.

  In S3 of FIG. 3, CPU 110 displays screen SC1 on display unit 170 in accordance with a display command for function selection screen SC1. Specifically, when the received operation command is a display command, the CPU 110 displays a screen represented by the display screen data on the display unit 170 using the display screen data included in the display command. Since the display command transmitted by the control server 200 in S2 includes display screen data representing the function selection screen SC1, the function selection screen SC1 is displayed on the display unit 170 in S3.

  The function selection screen SC1 in FIG. 3 includes options indicating three types of server cooperation functions (Fax to Cloud function, Scan to Cloud function, and Download Print function). That is, the user can use the Scan to Cloud function and the Download Print function in addition to the above-described Fax to Cloud function as the server cooperation function. The Scan to Cloud function is a function for transmitting the generated scan data to a designated storage server when the multifunction peripheral 100 generates scan data using the scanner unit 150. The designated storage server is a storage server (for example, storage server 310) that provides a storage service (for example, storage service SN1) specified by the user. The Download Print function is a function in which the multi-function device 100 downloads image data stored in a specified storage server and prints an image represented by the downloaded image data using the printer unit 140.

  The user selects a server cooperation function to be used by selecting one option on the function selection screen SC1. Here, the explanation is continued assuming that the Fax to Cloud function is selected. In S4, the CPU 110 transmits function selection information (for example, information indicating the Fax to Cloud function) indicating the selection result of the server cooperation function by the user to the control server 200. As described above, when the CPU 110 receives a display command, it receives a user operation on the screen displayed according to the display command, and then transmits a notification of the operation result of the user. The next designated URL included in the display command is used as the destination URL of the notification of the user operation result. As a result, the user operation result is appropriately notified to the control server 200.

  As described above, the CPU 210 can display various display screens functioning as a user interface on the multi-function device 100 by transmitting display commands to the multi-function device 100. And CPU210 can acquire the operation result of the user performed via the said display screen. As a result, the CPU 210 can cause the user to input information necessary for executing the server cooperation function such as the Fax to Cloud function. For example, there is a possibility that the user needs to input new information by changing the specifications of the storage services SN1 to SN3. Even in such a case, the vendor updates the display screen data to be transmitted from the control server 200, thereby allowing the user to input new information without updating the computer program PG1 of the multifunction peripheral 100. Can do.

  When the control server 200 receives the function selection information, the CPU 210 transmits a display instruction for the function explanation screen SC2 to the multi-function device 100 (S5). When the multi-function device 100 receives a display command for the screen SC2, the CPU 110 displays the screen SC2 on the display unit 170 according to the command (S6). The function explanation screen SC2 of FIG. 3 includes an explanation of the Fax to Cloud function and an “OK” button. When the user presses the “OK” button, the CPU 110 transmits a request for the next command to the control server 200 (S7).

  When the control server 200 receives the request for the next command, the CPU 210 transmits a display command for the function valid / invalid setting screen SC3 to the multi-function device 100 (S8). When the multifunction device 100 receives the display instruction for the screen SC3, the CPU 110 displays the screen SC3 on the display unit 170 in accordance with the instruction (S9). The function enable / disable setting screen SC3 in FIG. 3 has an option indicating that the Fax to Cloud function is enabled (ON option in FIG. 3) and an option indicating that the Fax to Cloud function is disabled (OFF in FIG. 3). Option). When the user selects any option, the CPU 110 transmits valid / invalid selection information indicating the selection result to the control server 200 (S10).

  When the control server 200 receives the valid / invalid selection information, the CPU 210 determines based on the valid / invalid selection information whether an option indicating that the Fax to Cloud function is to be valid has been selected (S11). When the option indicating that the Fax to Cloud function is disabled is selected (S11: NO), the CPU 210 advances the process to S27 of FIG.

  When the option indicating that the Fax to Cloud function is to be enabled is selected (S11: YES), the CPU 210 transmits a display command for the service selection screen SC4 to the multi-function device 100 (S12). When the multi-function device 100 receives a display command for the screen SC4, the CPU 110 displays the screen SC4 on the display unit 170 according to the command (S13). The service selection screen SC4 in FIG. 3 includes a plurality of options indicating a plurality of selectable storage services SN1 to SN3. When the user selects an option indicating a storage service to be used as a storage destination, the CPU 110 transmits service selection information indicating a selection result to the control server 200 (S14).

  When the control server 200 receives the service selection information, the CPU 210 transmits a command to transmit the account information AD to the control server 200 to the multifunction peripheral 100 (S15). The transmission command to the control server 200 is a kind of operation command transmitted from the control server 200 to the multifunction peripheral 100. The transmission command to the control server 200 is a command for causing the MFP 100 to transmit data to be transmitted that the MFP 100 has to the control server 200. The transmission command to the control server 200 in FIG. 5B includes information indicating a transmission command, an ID of data to be transmitted, and a next designated URL.

  When the multifunction device 100 receives the account information AD transmission command, the CPU 110 transmits the account information AD (FIG. 2) included in the service information list SL to the control server 200 in accordance with the received transmission command (S16). Specifically, when the received operation command is a transmission command to the control server 200, the CPU 110 transmits the data in the nonvolatile storage device 120 based on the ID of data to be transmitted included in the transmission command. Identify the target data. Since the transmission command transmitted by the control server 200 in S15 includes the ID indicating the account information AD as the ID of the data to be transmitted, the account information AD is specified. CPU 110 transmits the data to be transmitted using the next designated URL included in the transmission command as the destination URL. As a result, the transmission target data is appropriately transmitted to the control server 200.

  In this way, the control server 200 (CPU 210) can acquire various information stored in the multifunction device 100 by transmitting a transmission command to the control server 200 to the multifunction device 100. As a result, the CPU 210 can acquire information necessary for executing the server cooperation function such as the Fax to Cloud function from the multifunction peripheral 100. For example, there is a possibility that information to be acquired from the multifunction device 100 needs to be changed due to a specification change of the storage services SN1 to SN3. Even in such a case, the vendor updates the display screen data to be transmitted from the control server 200, so that new information can be obtained from the multifunction device 100 without updating the computer program PG1 of the multifunction device 100. Can be acquired.

  When the control server 200 receives the account information AD, the CPU 210 generates display screen data representing the account selection screen SC5 based on the received service selection information and account information AD (S17). Specifically, the CPU 210 identifies the selected storage service based on the service selection information received in S14. The CPU 210 extracts the user name associated with the selected storage service from the account information AD received in S16. For example, when the selected storage service is the storage service SN2, two user names “Alice” and “Bob” are extracted from the account information AD included in the service information list SL of FIG. The The CPU 210 generates display screen data representing the account selection screen SC5 including options indicating the extracted user name.

  In S18 of FIG. 4, the CPU 210 transmits a display command for the account selection screen SC5 represented by the display image data generated in S17 to the multi-function peripheral 100. When the multi-function device 100 receives a display command for the screen SC5, the CPU 110 displays the screen SC5 on the display unit 170 according to the command (S19). In the example of FIG. 4, the account selection screen SC5 includes two options indicating the user names “Alice” and “Bob”. When the user selects any option, the CPU 110 transmits account selection information indicating the selection result to the control server 200 (S20).

  When the control server 200 receives the account selection information, the CPU 210 transmits a transmission command to the control server 200 for the setting information in the display only mode to the multifunction peripheral 100 (S21). When the multi-function device 100 receives a transmission command for the setting information in the display only mode, the CPU 110 sends the control server 200 to the control server 200 according to the received transmission command in the display only mode included in the FAX general setting information FG in FIG. Setting information is transmitted (S22).

  When the control server 200 receives the setting information for the display only mode, the CPU 210 generates display screen data representing the function setting screen SC6 (S23). FIG. 6 is a flowchart of display screen data generation processing representing the function setting screen SC6.

  In S110, the CPU 210 determines whether the format that can be stored by the selected storage service (the above-described possible format) is only the JPEG format or an arbitrary format. This determination is performed with reference to the service usage information SA (FIG. 2) stored in the nonvolatile storage device 220. When the possible format of the selected storage service is only the JPEG format (S110: YES), the format option is determined to be only the JPEG format (S120). When the possible format of the selected storage service is not only the JPEG format (S110: NO), the format choices are determined as three formats: JPEG format, PDF, and TIFF (S115).

  As described above, the format options are determined according to the present embodiment. The possible format of the storage service is only the JPEG format or an arbitrary format. This is because it is possible to generate image files in three formats: JPEG format, PDF, and TIFF. In general, a format that is a storage service-capable format and that can be generated by the MFP 100 may be determined as an option.

  In S125, the CPU 210 determines whether the display only mode is valid (ON) or invalid (OFF) in the multifunction peripheral 100 based on the setting information of the display only mode received in S22 of FIG. When the display only mode is valid (S125: YES), the CPU 210 determines not to display the backup print setting button so that the user does not set whether or not to execute the backup print (S130). . This is because, when the display only mode is valid, even if backup printing is set to be valid, the FAX image is not printed in the FAX reception processing (FIG. 7) described later. It is because there is no meaning to set to. The fact that the backup print setting button is not displayed means that the backup print setting is maintained at the initial value (invalid). When the display only mode is invalid (S125: NO), the CPU 210 determines that the backup print setting button should be displayed in order to allow the user to set whether or not to execute the backup print (S135). ). If the display only mode is invalid and the fax to cloud function is valid, whether or not to print a fax image according to the backup print setting in the fax reception processing (FIG. 7) described later. It is because it is decided.

  In S140, the CPU 210 generates display image data representing the function setting screen SC6 based on the determination result regarding the format option and the determination result regarding the backup print setting button. The generated display image data includes data representing a sub screen (described later) of the function setting screen SC6.

  In S24 of FIG. 4, the CPU 210 transmits a display command for the function setting screen SC6 represented by the display image data generated in S23 to the multi-function device 100. When the multi-function device 100 receives the display instruction for the screen SC6, the CPU 110 displays the screen SC6 on the display unit 170 according to the instruction (S25). The function setting screen SC6 in FIG. 4 includes a “format” setting button, a “backup printing” setting button, and an “OK” button. When the “Format” setting button is pressed, a sub-screen SB1 including the format options determined in S115 or S120 of FIG. The user can select a format (file format) used when transmitting FAX image data to the storage server via the sub-screen SB1. The “backup print” setting button is not displayed when it is determined in S130 in FIG. 6 that the setting button is not displayed, and it is determined in S135 in FIG. 6 that the setting button is displayed. If it is, it will be displayed. When the “backup printing” setting button is pressed, a sub-screen SB2 including an option indicating valid (ON) and an option indicating invalid (OFF) is displayed on the display unit 170. The user can select whether to enable backup printing via the sub-screen SB2.

  When the user presses the “OK” button, the CPU 110 transmits function setting information indicating the format selection result and the backup print selection result to the control server 200 (S26).

  When the control server 200 receives the function setting information, the CPU 210 transmits a display instruction for the setting confirmation screen SC7 to the multi-function device 100 (S27). When the multi-function device 100 receives a display command for the screen SC7, the CPU 110 displays the screen SC7 on the display unit 170 according to the command (S28). The setting confirmation screen SC7 of FIG. 4 includes a display of setting contents of a plurality of items set via the above-described screens SC4 to SC6, an “OK” button, and a “Return” button.

  If it is determined in S11 of FIG. 3 that the option indicating that the Fax to Cloud function is disabled is selected (S11: NO), and the process proceeds to S27, the process proceeds to S28. A setting confirmation screen (not shown) different from the setting confirmation screen SC7 of FIG. 4 is displayed. The setting confirmation screen in this case includes a display of disabling the Fax to Cloud function as a display of the setting contents.

  When the “OK” button or the “Return” button is pressed on the setting confirmation screen SC7, in S29, the CPU 110 instructs the control server 200 whether the “OK” button is pressed or “Return”. A confirmation result notification indicating whether the button has been pressed is transmitted. When the CPU 210 receives a confirmation result notification indicating that the “return” button has been pressed, the CPU 210 returns to the process of S8 or S12 (not shown).

  When the CPU 210 receives a confirmation result notification indicating that the “OK” button has been pressed, the CPU 210 transmits a setting information write command to the multifunction peripheral 100 (S30). The write command is a kind of operation command transmitted from the control server 200 to the multifunction device 100. The write command is a command for writing the write target data to the write target area in the non-volatile storage device 120 of the multifunction peripheral 100. The write command in FIG. 5C includes information indicating that it is a write command, write target data, write destination information that specifies a write target area, and a next specified URL. The write destination information is information indicating the address of the write target area, for example.

  In the setting information writing command transmitted in S30, the data to be written is setting information regarding the Fax to Cloud function received via the screens SC3 to SC6 in FIGS. The writing target area is a storage area in which setting information indicating whether the Fax to Cloud function of the FAX general setting information FG in FIG. 2 is valid or invalid, and the Fax to Cloud setting information FC is stored. It is.

  When the multi-function device 100 receives the write command, the CPU 110 writes the write target data in the write target area in the nonvolatile storage device 220 in accordance with the received write command (S31). As a result, the FAX general setting information FG and the Fax to Cloud setting information FC of the multifunction peripheral 100 are updated according to the user's operation on the screens SC3 to SC6. In S <b> 32, the CPU 110 transmits a write result notification indicating that writing according to the write command is completed to the control server 200. Specifically, CPU 110 transmits information indicating the writing result by using the next designated URL included in the writing command as the destination URL.

  As described above, the control server 200 (CPU 210) can write various information in the non-volatile storage device 220 of the multifunction device 100 by transmitting the write command to the multifunction device 100. As a result, for example, the CPU 210 can change the setting of the multifunction peripheral 100 necessary for executing the server cooperation function such as the Fax to Cloud function. The CPU 210 can cause the multifunction peripheral 100 to store information necessary for executing the server cooperation function. For example, it may be necessary to change the setting of the multifunction device 100 or to store new information in the multifunction device 100 by changing the specifications of the storage services SN1 to SN3. Even in such a case, the vendor updates the computer program PG2 of the control server 200 so as to transmit an appropriate write command, so that the compound program is not updated without updating the computer program PG1 of the multifunction device 100. Changing the setting of the machine 100 and storing new information in the multifunction machine 100 can be realized.

  When the control server 200 receives the writing result notification, the CPU 210 transmits a display instruction for the setting completion screen SC8 to the multi-function device 100 (S33). The display command for the screen SC8 does not include the next designated URL (FIG. 5A). When the multifunction device 100 receives a display command for the screen SC8, the CPU 110 displays the screen SC8 on the display unit 170 in accordance with the command. The setting completion screen SC8 in FIG. 4 includes an indication that the processing of the fax to cloud function has been completed, and a “OK” button. When the “OK” button is pressed, the CPU 110 ends the setting process. The CPU 110 can determine that the setting process should be terminated when the next designated URL is not included in the display command of the setting completion screen SC8.

  According to the setting process described above, the control server 200 can appropriately set the Fax to Cloud function in accordance with the user's intention by transmitting the various operation commands shown in FIG. it can.

A-2-3. Processing at the time of FAX reception Processing that is executed in response to reception of facsimile data when the MFP 100 receives facsimile data via the telephone line IF 190 (hereinafter also referred to as processing at the time of FAX reception) will be described. FIG. 7 is a flowchart of processing when receiving a fax.

  When the facsimile data is received, in S310, the CPU 110 stores the received facsimile data in the nonvolatile storage device 120 of the multifunction peripheral 100. In S315, the CPU 110 refers to the FAX general setting information FG (FIG. 2A) and determines whether or not the display only mode is valid (ON). If the display only mode is valid (S315: YES), CPU 110 advances the process to S335 without printing a FAX image. That is, when the display only mode is valid, the setting of the display only mode has priority over the setting of backup printing described later, and the FAX image is not printed.

  When the display only mode is invalid (S315: NO), the CPU 110 refers to the FAX general setting information FG (FIG. 2A) and the Fax to Cloud function is valid (ON) in S320. Determine whether or not. If the Fax to Cloud function is invalid (S320: NO), the CPU 110 prints a FAX image in S330 and advances the process to S335. That is, when the display only mode is invalid (S315: NO) and the fax to cloud function is invalid (S320: NO), the FAX image is printed.

  When the Fax to Cloud function is valid (S320: YES), the CPU 110 validates the backup printing in the Fax to Cloud function based on the Fax to Cloud setting information FC (FIG. 2B) in S325 ( ON) or not. If the backup printing is invalid (S325: NO), the CPU 110 advances the process to S335 without printing a FAX image. On the other hand, if backup printing is valid (S325: YES), the CPU 110 prints a FAX image in S330 and advances the process to S335. That is, when the display only mode is invalid (S315: NO) and the fax to cloud function is valid (S320: YES), the fax image is printed according to the backup print setting in the fax to cloud function. It is determined whether or not.

  In S335, the CPU 110 determines whether the Fax to Cloud function is valid. If the Fax to Cloud function is valid (S335: YES), the CPU 110 executes Fax to Cloud processing in S340. When executing the Fax to Cloud process, the facsimile data is deleted during the Fax to Cloud process, as will be described later.

  When the Fax to Cloud function is invalid (S335: NO), the CPU 110 determines whether or not a FAX image has been printed in S345. If the CPU 110 executes printing of a FAX image in S330 (S345: YES), the facsimile data is deleted from the non-volatile storage device 120 in S350, and the process ends. That is, when the fax to cloud function is invalid and the FAX image is printed, the facsimile data is immediately deleted. On the other hand, if the FAX image is not printed (S345: NO), the CPU 110 ends the process without deleting the facsimile data. That is, when the fax to cloud function is invalid and the FAX image is not printed, the facsimile data is kept stored in the nonvolatile storage device 120. In this case, the facsimile data is deleted when the user gives an instruction.

A-2-4. Fax to Cloud Processing FIGS. 8 and 9 are flowcharts of Fax to Cloud processing. In S <b> 50, CPU 110 transmits a FAX reception notification indicating that facsimile data has been received to control server 200. That is, when the fax to cloud function is valid, communication between the multifunction peripheral 100 and the control server 200 is started in response to reception of facsimile data. Note that the reception notification includes the ID (client ID) of the MFP 100. When the control server 200 receives the FAX reception notification, the CPU 210 causes the MFP 100 to perform a FAX in the previous fax to cloud process based on the error information EI (FIG. 2) and the client ID included in the reception notification. Specify the result of sending (uploading) image data. The CPU 210 determines whether or not an error has occurred in the transmission of the specified previous FAX image data (S51).

  If an error has occurred during transmission of FAX image data in the previous fax to cloud process (S51: YES), the CPU 210 determines whether the error is the above-described first type error (S52). ). If the error that occurred in the transmission of FAX image data in the previous Fax to Cloud process is the first type error (S52: YES), the process at the time of the first type error that will be described later is executed. The

  If no error has occurred in the transmission of FAX image data in the previous Fax to Cloud process (S51: NO), and the error that occurred in the transmission of FAX image data in the previous Fax to Cloud process is the first type error Instead, if it is the second type error (S52: NO), the CPU 210 advances the process to S53 in order to transmit the FAX image data to the storage server.

  In S <b> 53, the CPU 210 transmits a transmission command for the service information list SL (FIG. 2) to the multifunction peripheral 100.

  When the MFP 100 receives the service information list SL transmission command, the CPU 110 transmits the service information list SL to the control server 200 according to the command (S54).

  When the control server 200 receives the service information list SL, the CPU 210 transmits a transmission command for the FAX reception list FL (FIG. 2) to the multi-function device 100 (S55). When the MFP 100 receives a transmission command for the FAX reception list FL, the CPU 110 transmits the FAX reception list FL to the control server 200 according to the transmission command (S56). As a result, the control server 200 receives the FAX reception list FL.

  In S57, the CPU 210 selects one or more facsimile data in the list FL as a processing target one by one based on the FAX reception list FL. The facsimile data to be selected is received by the multi-function device 100 and stored in the non-volatile storage device 220 of the multi-function device 100, and FAX image data corresponding to the facsimile data is transmitted (upload) to the storage server. This is facsimile data that has not been). In the present embodiment, one facsimile data corresponding to one or more entries EN (FIG. 2) included in the FAX reception list FL is selected. In this embodiment, since fax to cloud processing is executed every time facsimile data is received, the number of facsimile data to be selected is often one. However, for example, in the process immediately after the Fax to Cloud function is changed from disabled to enabled, the number of facsimile data to be selected becomes multiple, including the facsimile data received when the Fax to Cloud function is disabled. Become. In addition, when transmission of the FAX image data to the storage server fails due to a network failure or the like in the previous process, the facsimile data to be selected including the facsimile data corresponding to the FAX image data that failed to be transmitted is displayed. There can be multiple. In such a case, FAX image data is transmitted to the storage server for each of a plurality of facsimile data in this processing.

  In S58, the CPU 210 refers to the service information list SL and selects the accounts to be selected one by one as the processing target. Specifically, the CPU 210 extracts, as selection target accounts, accounts for which the corresponding FAX image transmission setting is “ON” from one or more accounts whose account information AD is registered in the service information list SL. To do. In the example of FIG. 2, the account of the storage service SN1 whose user name is “Alice” and the account of the storage service SN2 whose user name is “Bob” are the accounts to be selected. A plurality of accounts associated with the same storage service and having different user names may be selected. In addition, a plurality of accounts associated with different storage services and having the same user name may be selected.

  In S59, the CPU 210 determines that the facsimile data to be processed (for example, facsimile data having the FAX ID “001” in FIG. 2C) and the account to be processed (for example, the user name in FIG. 2B is “Alice”). And a transmission start command corresponding to the storage service SN1), and transmits the transmission start command to the multi-function device 100. The transmission start command is a kind of operation command transmitted from the control server 200 to the multifunction device 100.

  FIG. 10 is a diagram illustrating an example of an operation command used for Fax to Cloud processing. The transmission start command in FIG. 10A includes information indicating a transmission start command, target FAX ID, target format information, and three types of transmission destination URLs. The target FAXID is the FAXID of the facsimile data to be processed (for example, “001” in FIG. 2C). The target format information is format information (for example, “JPEG” in FIG. 2B) corresponding to the account to be processed in the service information list SL. As described later, the three types of transmission destination URLs include an upload information request transmission destination URL, an upload result transmission destination URL, and a transmission completion notification transmission destination URL. All of the three types of destination URLs are URLs indicating resources in the control server 200.

  In S59, when the multi-function device 100 receives the transmission start command, the CPU 110 starts processing for transmitting the FAX image data to the storage server in accordance with the transmission start command. Specifically, in S60, CPU 110 executes format conversion processing. The format conversion process is a process for generating FAX image data using facsimile data specified by the target FAX ID included in the transmission start command, that is, facsimile data to be processed. By this processing, one or more image files having a format indicated by the target format information included in the transmission start command are generated. By including the target format information in the transmission start command in this way, the control server 200 controls the multifunction peripheral 100 so as to transmit FAX image data (one or more image files) of an appropriate format to the storage server. be able to.

  Here, when the facsimile data to be processed includes data for N pages (N is an integer of 1 or more) and the format indicated by the target format information is PDF or TIFF, the data for N pages. One image file is generated as FAX image data. This is because PDF and TIFF are formats that can store a plurality of images in one file and can construct a multi-page file that handles each image as an image for one page.

  When the facsimile data to be processed includes data for N pages (N is an integer equal to or greater than 1) and the format indicated by the target format information is JPEG format, the facsimile image data for N pages , N image files are generated. This is because the JPEG format is a format in which a multi-page file cannot be configured and one image is stored in one file.

  In S <b> 61, the CPU 110 transmits an upload information request to the control server 200. In the transmission of the upload information request, the upload information request transmission destination URL included in the transmission start command is used as the destination URL. Note that the upload information request includes information indicating the data amount (unit is, for example, bytes) of the FAX image data generated in S60. Information indicating the amount of FAX image data is described for each image file. For example, when N image files are generated as FAX image data corresponding to one facsimile data, the upload information request includes information indicating the data amount of each of the N image files. .

  When the control server 200 receives the upload information request, the CPU 210 generates the upload command of FIG. 10B (S62).

  FIG. 11 is a flowchart of processing for generating an upload command. In S410, the CPU 210 determines a file name of an image file (hereinafter also referred to as a target image file) that is a target of an upload command among one or more image files as FAX image data to be transmitted. For example, the file name is determined as “reception date / time_serial number.format name”. For example, in step S80, N JPEG format image files are generated using facsimile data of FAXID “001” (FIG. 2C). When the image file on the first page is the target image file, the file name is determined as “TM1_001.jpg”.

  In S420, the CPU 210 refers to the service information list SL and determines the type of the storage service (hereinafter also referred to as the target storage service) corresponding to the account to be processed. If the target storage service is the storage service SN1, the CPU 210 advances the process to S470 without performing any special processing.

  When the target storage service is the storage service SN2, the CPU 210 obtains a temporary token using the token of the processing target account. The temporary token is a token whose usable period (for example, one day) is shorter than that of a normal token. The temporary token is generated, for example, by executing a predetermined generation program. For example, the generation program is published together with the API by the business operator of the storage service SN2. The temporary token may be acquired from the storage server 320 by the CPU 210 transmitting an issuance request to the storage server 320 that provides the storage service SN2.

  When the target storage service is the storage service SN3, the CPU 210 generates a folder unique to the storage service SN3 in the storage server 330 that provides the storage service SN3 (S450). For example, the CPU 210 uses the token of the account to be processed to access the storage server 330 and generate a folder for storing FAX image data. In S460, the CPU 210 acquires a folder ID that is an identifier of the generated folder.

  In S470, the CPU 210 determines an upload destination URL according to the target storage service. As described above, the upload destination URL is described in the service usage information SA (FIG. 2) for each storage service.

  In S480, the CPU 210 generates template data for upload according to the target storage service. The template data is data created in a data format used when transmitting the target image file to the target storage server, and includes a parameter group necessary for transmitting the target image file. If template data has been generated, data to be transmitted can be easily generated by adding the target image file to the template data. Template data is different for each storage service. For example, as shown in FIG. 10B, the template data generated for the storage service SN1 includes the token of the account to be processed, the file name determined in S410, the format information of the target image file, the target Data amount information of the image file. The template data generated for the storage service SN2 includes the temporary token acquired in S440 instead of the token of the account to be processed. The template data generated for the storage service SN3 further includes the folder ID acquired in S460.

  In S <b> 63 of FIG. 8, the CPU 210 transmits an upload command to the multi-function device 100. The upload command is a kind of operation command transmitted from the control server 200 to the multifunction peripheral 100. The upload command in FIG. 10B includes information indicating that it is an upload command, the upload destination URL determined in S470 in FIG. 11, and the template data generated in S480 in FIG.

  When the MFP 100 receives the upload command, the CPU 110 transmits (uploads) the target image file to the target storage server (for example, the storage server 310) in accordance with the received upload command (S64). Specifically, the CPU 110 adds the target image file to the template data included in the upload command, and generates transmission target data. The CPU 110 transmits the transmission target data using the upload information request transmission destination URL included in the upload command as the destination URL. In response to one upload command, one image file is transmitted to the storage server. For example, if N JPEG format image files are generated as FAX image data for N pages in S60, the process of S64 is repeatedly executed N times as described later. In one processing of S64, one image file for one page among N image files is transmitted to the storage server.

  In S65, the storage server executes a storage process. Specifically, the storage server performs an authentication process using a token included in data transmitted from the multifunction device 100. When determining that the token is authentic, the storage server stores the target image file in a storage area in the storage server assigned to the account corresponding to the token. If an error occurs during the saving process, the saving server interrupts the saving process without completing the saving of the target image file.

  In S <b> 66, the storage server transmits an upload result notification indicating the result of the storage process, that is, the upload result, to the multifunction peripheral 100. The upload result notification includes information indicating that either the saving of the target image file has succeeded or the saving of the target image file has failed. In addition, when the upload result notification includes information indicating that the saving of the target image file has failed, the upload result notification further includes information indicating an error that has caused the failure. As described above, the error causing the failure includes the first type of error (for example, the authentication error, the storage capacity upper limit violation error, and the write authority violation error) and the second type of error (for example, Communication failure error, service stop error).

  In S67 of FIG. 9, when the multifunction peripheral 100 receives the upload result notification from the storage server, the CPU 110 transmits the received upload result notification to the control server 200. In the transmission of the upload result notification to the control server 200, the upload result transmission destination URL included in the transmission start command (FIG. 10A) is used as the destination URL.

  When the control server 200 receives the upload result notification, the CPU 210 determines whether the target image file has been successfully saved based on the upload result notification (S68). If the saving of the target image file has failed (S68: NO), the processing when an error occurs is executed.

  FIG. 12 is a flowchart of processing when an error occurs. In step S <b> 81, the CPU 210 transmits an interruption command for instructing interruption of transmission (upload) of FAX image data to the multifunction peripheral 100. The interrupt command in FIG. 10C includes information indicating that it is an interrupt command.

  When the MFP 100 receives the interruption command, the CPU 110 interrupts the transmission of the FAX image data according to the command, and transmits an upload interruption notification indicating that the transmission of the FAX image data is interrupted to the control server 200 ( S82). In transmitting the upload interruption notification to the control server 200, the transmission completion notification transmission destination URL included in the transmission start command of FIG. 10A is used as the destination URL.

  When the control server 200 receives the upload interruption notification, the control server 200 stores information indicating the error that has occurred as error information EI (FIG. 2) based on the upload result notification received in S67 (FIG. 9) ( S83).

  In S <b> 84, the CPU 210 transmits a display instruction for the error notification screen SC <b> 9 to the multi-function device 100. When the multifunction device 100 receives the display command for the screen SC9, the CPU 110 displays the error notification screen SC9 on the display unit 170 according to the command (S85). The error notification screen SC9 includes a message indicating the content of the error that has occurred and a “OK” button. When the “OK” button is pressed, the CPU 110 ends the fax to cloud process. Since the next designated URL is not included in the display instruction of the screen SC9, the CPU 110 can determine that the fax to cloud process should be terminated.

  On the other hand, when the saving of the target image file is successful (S68: YES in FIG. 9), the CPU 210 transmits a continuation instruction for instructing continuation of transmission (upload) of FAX image data to the multi-function device 100 (S69). ). The continuation instruction in FIG. 10D includes information indicating that it is a continuation instruction.

  When the multifunction device 100 receives the continuation command, in S70, the CPU 110 includes one or more image files as FAX image data that are not transmitted to the storage server (that is, not uploaded). Determine whether or not. That is, it is determined whether there is an untransmitted image file among one or more image files generated in S60 (FIG. 8) using the facsimile data to be processed. When the FAX image data format is the JPEG format, as described above, a plurality of image files can be generated for one piece of facsimile data to be processed. In this case, it can be determined in S70 that there is an untransmitted image file. When the format of FAX image data is PDF or TIFF, one image file is generated for one facsimile data to be processed. In this case, it is not determined in S70 that there is an untransmitted image file.

  If there is an untransmitted image file (S70: YES), the CPU 110 returns the process to S61 in FIG. As a result, an untransmitted image file is selected as a target image file, and a series of processing (S61 to S69) relating to transmission of the target image file to the storage server is executed. As a result, when N JPEG format image files for N pages are generated in S60, N upload instructions corresponding to N pages are transmitted from the control server 200 to the multifunction peripheral 100. (S63). Then, every time the MFP 100 receives one upload command, the MFP 100 transmits the image files one by one to the storage server (S64). In other words, the CPU 110 executes transmission of one image file corresponding to one upload command N times according to N upload commands. Accordingly, when N image files are generated as N pages of FAX image data, the control server 200 controls the multifunction peripheral 100 to appropriately transmit the FAX image data to the target storage server. be able to.

  When there is no unsent image file (S70: NO), in S71, the CPU 110 transmits an upload completion notification indicating that transmission (upload) of one FAX image data is completed to the control server 200. . In the transmission of the upload completion notification to the control server 200, the transmission completion notification transmission destination URL included in the transmission start command is used as the destination URL.

  When the control server 200 receives the upload completion notification, in S72, the CPU 210 determines whether or not all accounts to be selected have been selected as processing targets. If all the accounts to be selected have not been selected (S72: NO), the CPU 210 returns the process to S58 in FIG. As a result, the processing of S59 to S71 described above is repeated for another account to be selected. As a result, when the number of accounts to be selected is M (M is an integer equal to or greater than 1), FAX image data corresponding to one piece of processing-target facsimile data is transmitted M times.

  If all accounts to be selected have been selected (S72: YES), the CPU 210 transmits a facsimile data deletion command to the multi-function device 100 (S73). The delete command is a kind of operation command transmitted from the control server 200 to the multifunction peripheral 100. The deletion command is a command for deleting data to be deleted from the nonvolatile storage device 120 of the multifunction peripheral 100. The delete command in FIG. 10E includes information indicating that it is a delete command, FAXID of facsimile data to be deleted, and next designated URL.

  When the multi-function device 100 receives the delete command, the CPU 110 deletes the facsimile data having the FAX ID included in the delete command from the nonvolatile storage device 120 according to the command (S74). Deletion from the storage device is to replace the data to be deleted with other data (for example, data representing 0). Alternatively, the deletion from the storage device may be to allow writing to the storage area in which the data to be deleted is stored, that is, to release the storage area. In S <b> 75, the CPU 110 transmits a deletion completion notification indicating that the deletion of facsimile data is completed to the control server 200. The next designated URL included in the deletion command is used as the destination URL of the deletion completion notification. When the facsimile data is deleted from the nonvolatile storage device 120, the CPU 110 also deletes the FAX image data generated using the deleted facsimile data from the volatile storage device 130.

  When the control server 200 receives the deletion completion notification, in S76, the CPU 210 determines whether or not all the facsimile data to be selected has been selected as the processing target. When all the facsimile data to be selected has not been selected (S76: NO), the CPU 210 returns the process to S57 in FIG. As a result, the processing of S58 to S75 described above is repeated for another facsimile data to be selected. As a result, when the FAX reception list FL transmitted from the multifunction device 100 to the control server 200 in S56 includes a plurality of entries EN corresponding to the plurality of received facsimile data, the control server 200 transmits to the multifunction device 100. A transmission start command and an upload command are transmitted for each of the plurality of received facsimile data (S59, S63). Then, in response to the transmission start command or upload command, the multi-function device 100 transmits FAX image data to each of the plurality of received facsimile data to the storage server (S64). Therefore, the control server 200 can control the multifunction peripheral 100 so as to transmit a plurality of FAX image data corresponding to a plurality of received facsimile data to an appropriate storage server.

  When all the facsimile data to be selected are selected (S76: YES), the CPU 210 indicates that the transmission (uploading) of the FAX image data to the storage server in this Fax to Cloud processing has been normally completed. Information is recorded in the EI (S77).

  In S <b> 78, the CPU 210 transmits an end screen display command to the multifunction peripheral 100. When the MFP 100 receives the end screen display command, the CPU 110 displays an end screen (not shown) on the display unit 170 in accordance with the command (S79). The end screen includes a message indicating that transmission of the FAX image data corresponding to the received facsimile data to the storage server has ended, and a “OK” button. When the “OK” button is pressed, the CPU 110 ends the fax to cloud process. Since the end screen display command does not include the next designated URL, the CPU 110 can determine that the fax to cloud processing should be terminated.

  If it is determined in S52 of FIG. 8 that the first type of error has occurred in the transmission of FAX image data in the previous Fax to Cloud process (S52: YES), Processing is executed.

  FIG. 13 is a flowchart of the process when the first type of error occurred last time. In S <b> 91, the CPU 210 transmits a display instruction for the previous error notification screen SC <b> 10 to the multifunction peripheral 100. When the multi-function device 100 receives a display command for the screen SC10, the CPU 110 displays the screen SC10 on the display unit 170 according to the command (S92). The previous error notification screen SC10 includes a message indicating the content of the error that occurred in the previous Fax to Cloud process, an “End” button, and an “UPLOAD” button. The “End” button is a button for instructing to end the Fax to Cloud processing without transmitting the FAX image data to the storage server. The “UPLOAD” button is a button for instructing to continue the Fax to Cloud processing in order to transmit (upload) the FAX image data to the storage server.

  For example, when the user has not executed the procedure for eliminating the first type of error and determines that the same error occurs when the transmission of the FAX image data is executed again, the user presses the “END” button. Press. For example, when the user has determined that the first type of error has been resolved and currently it is possible to transmit FAX image data, the user presses the “UPLOAD” button. .

  When one of the “End” button and the “UPLOAD” button is pressed, the CPU 110 sends information indicating which button is pressed to the control server 200, that is, which instruction is given by the user. Instruction selection information indicating whether it has been selected is transmitted (S93).

  When the control server 200 receives the instruction selection information, the CPU 210 determines whether or not it is instructed to end the Fax to Cloud process based on the instruction selection information (S94). When it is not instructed to end the Fax to Cloud process (S94: NO), that is, when an instruction to continue the Fax to Cloud process is given, the CPU 210 proceeds to S53 of FIG. As a result, as described above, transmission of FAX image data to the storage server is executed.

  When an instruction to end the Fax to Cloud process is given (S94: YES), the CPU 210 transmits an end screen display command to the multi-function device 100 (S95). When the multi-function device 100 receives the display command, the CPU 110 displays an end screen (not shown) on the display unit 170 in accordance with the received display command (S96). The end screen includes a message indicating that the Fax to Cloud processing has ended, and a “OK” button. When the “OK” button is pressed, the CPU 110 ends the fax to cloud process. Since the end screen display command does not include the next designated URL, the CPU 110 can determine that the fax to cloud processing should be terminated.

  As understood from the above description, when the multifunction device 100 receives the first facsimile data in a state where the fax to cloud function is valid, the multifunction device 100 and the control server 200 communicate in response to the reception. Thus, the Fax to Cloud process (also called the first process) is executed. In this first process, the multifunction peripheral 100 (CPU 110) tries to transmit (upload) the first FAX image data corresponding to the first facsimile data to the storage server in accordance with an instruction from the control server 200 (CPU 210). (S64 in FIG. 8). If transmission to the storage server fails, information (error information EI (FIG. 2)) indicating an error causing the failure is recorded in the control server 200 as an upload result, and the first processing is performed. The process is terminated (S81 to 85 in FIG. 12).

  Thereafter, when the multifunction device 100 receives the second facsimile data, the multifunction device 100 and the control server 200 communicate with each other in response to the reception, so that the fax to cloud processing (both the second processing is performed). Is called). In the second process, when the upload result of the first FAX image data in the first process indicates the above-described first type error (S52: YES in FIG. 8), the user sends a fax to cloud. If there is no instruction to continue the process, the Fax to Cloud process is terminated (S91 to S96 in FIG. 13). That is, transmission of the second FAX image data corresponding to the second facsimile data to the storage server is not attempted. Further, in the second process, when the upload result of the first FAX image data in the first process indicates the above-described second type error (S52: NO in FIG. 8), the Fax to Cloud process is performed. Is continued (S53 to S79 in FIGS. 8 and 9). That is, transmission of the second FAX image data to the storage server is attempted (S64). As a result, it is possible to reduce the waste of communication that may occur between the multifunction device 100 and the storage server.

  Specifically, in the present embodiment, the first type error is an error that is difficult to be resolved unless a user takes action. That is, when a first type error such as an authentication error, a storage capacity upper limit violation error, or a write authority violation error occurs during an attempt to send the first FAX image data, the user or the like takes no action. In such a case, there is a relatively high possibility that the same first type error will occur even when attempting to transmit the second FAX image data. As a result, the same error as the first type error that occurred in the first process occurs despite the attempt to transmit the second FAX image data in the second process, and the second FAX There is a high possibility that image data transmission will fail. Then, communication waste occurs. According to the present embodiment, such inconvenience can be effectively reduced. Further, waste of communication between the multifunction device 100 and the control server 200 can be reduced. For example, wasteful communication of S53 to S56, S59, S61, and S62 in FIG. 8 can be suppressed.

  Furthermore, even if a second type of error such as a communication failure error or a service stop error occurs when attempting to transmit the first FAX image data, the second type The possibility that the error is resolved is relatively high. In the present embodiment, as described above, when the upload result of the first FAX image data in the first process indicates the above-described second type error (S52: NO in FIG. 8), the second The FAX image data is uploaded (transmitted) to the storage server (S64). Therefore, even if an error occurs when attempting to transmit the first FAX image data, the second FAX image data can be appropriately transmitted to the storage server.

  In the above embodiment, the upload result of the first FAX image data indicates the first type error (S52: YES in FIG. 8), and there is no instruction to continue the fax to cloud process from the user. (S94 in FIG. 13: NO), transmission of the second FAX image data to the storage server is not attempted. In other words, even if the upload result of the first FAX image data indicates the first type of error, if there is an instruction from the user to continue the Fax to Cloud process (S94 in FIG. 13: YES) ), Transmission of the second FAX image data to the storage server is attempted (S64 in FIG. 8). As a result, the multi-function device 100 can appropriately try to transmit the second FAX image data to the storage server based on the user's intention. If the upload result of the first FAX image data indicates the second type of error, transmission of the second FAX image data is attempted regardless of whether there is an instruction from the user (S64 in FIG. 8). ). As a result, transmission of the second FAX image data can be appropriately attempted while reducing the user's instruction operation.

  When the upload result of the first FAX image data does not indicate the first type of error, for example, when the transmission of the first FAX image data is completed normally (S51: NO in FIG. 8), the storage server is sent. The transmission of the second FAX image data is attempted (S64 in FIG. 8). Therefore, for example, when the transmission result of the first FAX image data does not indicate an error, the transmission of the second FAX image data can be appropriately attempted.

  Further, the multifunction peripheral 100 executes the uploading of the second FAX image data in accordance with the transmission start command (FIG. 10A) and the upload command (FIG. 10B) transmitted from the control server 200. That is, the control server 200 determines whether or not to try to transmit the second FAX image data. Therefore, the control server 200 can appropriately control the transmission attempt of the second FAX image data by the multifunction peripheral 100 by transmitting the operation command. In addition, since the upload result of the first FAX image data to the storage server is notified to the control server 200 (S67 in FIG. 9), the control server 200 causes the MFP 100 to transmit the second FAX image data. It can be controlled appropriately.

  As can be understood from the above description, the transmission start command and the upload command in the above embodiment are examples of an image data transmission command, and the instruction to continue the Fax to Cloud process is an example of a specific instruction.

B. Variation:
(1) In the above embodiment, the CPU 210 of the control server 200 records the error information EI generated at the time of attempting to transmit the first FAX image data for each client such as the multifunction peripheral 100. Then, the CPU 210 determines whether or not to attempt transmission of the second FAX image data based on the error information EI. Instead, for each valid account information AD for which the fax image transmission setting in FIG. 2B is valid (ON), the error information EI generated when attempting to transmit the first FAX image data is recorded, Based on the error information EI, whether to attempt transmission of the second FAX image data may be determined for each valid account information AD.

  In this case, for example, the CPU 210 manages whether transmission of FAX image data to the storage server is completed for each piece of valid account information AD for one facsimile data. The CPU 210 transmits a facsimile data deletion command to the multi-function device 100 when transmission of the FAX image data to the storage server is completed for all valid account information AD. For example, it is assumed that there are two pieces of valid account information AD including first account information and second account information. In the first processing, transmission of FAX image data corresponding to specific facsimile data to the storage server using the first account information succeeds, and transmission to the storage server using the second account information fails. In this case, the specific facsimile data is not deleted from the multifunction peripheral 100. Then, in the second processing, the FAX image data corresponding to the specific facsimile data is retried to the storage server using the second account information, and when the transmission is successful, the specific facsimile data Is deleted.

(2) In the above embodiment, the error information EI (FIG. 2) is stored in the non-volatile storage device 220 of the control server 200 (FIG. 1). 120 may be stored. In this case, for example, the control server 200 may transmit an error information EI transmission command to the multi-function device 100 between S50 and S51 in FIG. Then, the multi-function device 100 may transmit the error information EI to the control server 200 in accordance with the transmission command. Further, the control server 200 may transmit a command for writing error information EI indicating the type of error that has occurred, to the multi-function peripheral 100, instead of S83 in FIG. The multi-function device 100 may store the error information EI in the nonvolatile storage device 120 in accordance with the write command.

(3) In the above embodiment, the control server 200 executes the process of determining whether or not to attempt to transmit the second FAX image data to the storage server (S51 and S52 in FIG. 8). . Instead, the MFP 100 may determine whether to try to transmit the second FAX image data to the storage server. In this case, for example, the processes of S51 and S52 in FIG. 8 and S91 to S96 in FIG. 13 are omitted. Then, as shown in the modification example (1), error information EI is stored in the nonvolatile storage device 120 of the multifunction peripheral 100. When receiving an upload command (S59 in FIG. 8) or receiving a transmission start command (S63 in FIG. 8), the CPU 110 of the multi-function device 100 refers to the error information EI and refers to the first FAX image. If the first type error has occurred during the data transmission attempt, it is determined that the transmission of the second FAX image data to the storage server is not attempted. The CPU 110 transmits the second FAX image data to the storage server when the second type of error has occurred when attempting to transmit the first FAX image data and when no error has occurred. Judge that it will try.

(4) The processes of FIGS. 3, 4, 8, 9, 12, and 13 of the above embodiment are realized by the multifunction peripheral 100 and the control server 200 cooperating. These processes may be executed by the multifunction peripheral 100 alone. In this case, the control server 200 may not be provided. For example, the service usage information SA, interpretation information IP, and error information EI stored in the non-volatile storage device 220 of the control server 200 in the above embodiment are stored in the non-volatile storage device 120 of the multifunction peripheral 100. 3, 4, 8, 9, 12, and 13, communication processing between the MFP 100 and the control server 200 is omitted, and processing executed by the control server 200 is combined. The CPU 110 of the machine 100 may be executed.

(5) In the above embodiment, if the first type of error has occurred when attempting to transmit the first FAX image data, the storage server is used unless there is an instruction to continue transmission of FAX image data from the user. No attempt is made to send the second FAX image data to the. Instead, if the first type of error has occurred when attempting to transmit the first FAX image data, an attempt to transmit the second FAX image data to the storage server is once made. However, if a specific trial condition is satisfied after that, transmission of the second FAX image data to the storage server may be attempted. The specific trial condition is, for example, that a specific period (for example, 1 day) has elapsed since the occurrence of the first type error, or a predetermined number (for example, 10) after the first type error has occurred. It may be that the facsimile data has been received or that the free space in the storage area for storing the facsimile data has become below the reference value.

(6) In the above embodiment, the facsimile data is received via the telephone line IF 190 and the analog telephone line network 90, but may be received via the Internet 80 and the network IF 180. That is, the facsimile data may be received by a so-called Internet fax mechanism. In Internet fax, for example, image data in a predetermined format is transmitted and received in a format attached to an e-mail described in a predetermined format. The transmission / reception of the e-mail is performed using, for example, the same protocol as that of normal e-mail, for example, SMTP (Simple Mail Transfer Protocol) or POP (Post Office Protocol). The facsimile data may be received via the telephone line IF 190 and the Internet 80. In this case, for example, the telephone line IF 190 is connected to a predetermined converter, and the converter is connected to the Internet 80. The exchange executes a conversion process between an analog signal transmitted / received via the telephone line IF 190 and a digital signal transmitted / received via the Internet 80.

(7) The format of FAX image data may be a format of facsimile data. In this case, the format conversion (S80) is omitted, and the facsimile data is transmitted (uploaded) as it is to the storage server as FAX image data.

(8) In each of the above embodiments, a part of the configuration realized by hardware may be replaced with software, and conversely, part or all of the configuration realized by software is replaced with hardware. You may do it.

  As mentioned above, although this invention was demonstrated based on the Example and the modification, Embodiment mentioned above is for making an understanding of this invention easy, and does not limit this invention. The present invention can be changed and improved without departing from the spirit and scope of the claims, and equivalents thereof are included in the present invention.
