JP 2014-44534 A

  Here, there is a recording apparatus that cannot execute the recording process for the data in the second format. In such a case, when the converted data in the second format is selected as the print data, the information processing apparatus described above needs to reverse-convert the converted data from the second format to the first format and transmit the converted data to the recording device. is there. For this reason, when conversion data exceeding the reverse conversion processing capability is selected as print data, there arises a problem that the recording process for the conversion data cannot be executed.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to reversely convert data obtained from a reading device and converted from the first format into the second format into the first format, and to the recording device. An object is to provide a program capable of executing a recording process.

  (1) A program described in this specification includes an operation unit, a reading device that reads an image recorded on a document and generates data in a first format, and an image represented by the data in the first format on a sheet. It can be executed by a computer connected to a recording apparatus that executes a recording process for recording. The program includes: a first data acquisition process for acquiring first data in the first format from the reading device; and a first method or a second method different from the first method, and the first data in the first format. A conversion process for converting to second data in a second format different from the above, a capability information acquisition process for acquiring capability information relating to the processing capability of an inverse conversion program for inversely converting the data in the second format into the first format, When it is assumed that the first data is converted into the second data by the first method, the first data is determined based on the capability information as to whether or not the inverse conversion program can reversely convert the second data. A determination process; a first storage process for storing the second data generated by the conversion process; and a first reception process for receiving a user operation for selecting data to be subjected to the recording process through the operation unit. An inverse transformation process for causing the inverse transformation program to inversely convert the second data into the inverse transformation data of the first format in response to accepting the selection of the second data in the first acceptance processing; In the conversion process when the computer executes a recording instruction process for causing the recording apparatus to record an image indicated by data on the sheet, and the first determination process determines that reverse conversion is possible, the first method The first data is converted into the second data, and the first data is converted into the second data by the second method in the conversion processing when the reverse determination is impossible in the first determination processing. .

  According to the above configuration, when it is assumed that the first data acquired from the reading device is converted to the second data by the first method, if the inverse conversion program cannot convert the second data, the first method is used. Instead, the conversion process is executed by the second method. As a result, the second data can be converted back into the first format and the recording apparatus can execute the recording process.

  (2) Preferably, the program causes the computer to execute a second determination process for determining whether or not the first data is composed of a plurality of pages, and determines that reverse conversion is impossible by the first determination process. In the conversion process when it is determined in the second determination process that the first data is composed of a plurality of pages, as the second method, each can be reverse converted by the reverse conversion program, and The first data is converted into a plurality of partial second data each corresponding to a part of pages constituting the second data, and the plurality of partial second data is converted into the second data in the first storage process. And in the inverse conversion process, each of the plurality of partial conversion data is inversely converted into the inverse conversion program.

  According to the above configuration, the first data that cannot be converted by the reverse conversion program is converted into a plurality of partial second data, each of which can be reverse converted. Thus, when the second data is selected as the target of the recording process, each partial second data is inversely converted into an inverse conversion program, and an image indicated by the inverse conversion data acquired from the inverse conversion program is displayed on the sheet. Can be recorded on the recording device.

  (3) Preferably, the program determines that the reverse conversion is impossible in the first determination process, and the conversion process in the case where the second determination process determines that the first data is composed of one page. In the second method, as the second method, the first data is compressed and then converted by the first method.

  According to the above configuration, when the first data cannot be divided into a plurality of partial second data, the first data is compressed prior to the conversion process of the first method. Two data can be obtained.

  (4) Preferably, the program determines that the reverse conversion is impossible in the first determination process, and determines that the first data is composed of one page in the second determination process. Causing the computer to execute a second accepting process for accepting a user operation for selecting whether or not to compress the first data through the operation unit, and accepting a user operation for selecting to compress in the second accepting process. In response to the user receiving the user operation for selecting not to compress the first data by compressing the first data and converting the first data by the first method. Then, the second storage process for storing the first data is executed by the computer instead of the conversion process and the first storage process.

  When the first data is compressed, the image quality of the image indicated by the first data is degraded. Therefore, as in the above configuration, it is desirable that the user select whether to convert the first data into the second format even if it is compressed or to store the first data in the first format as it is.

  (5) Preferably, the processing capability includes that the data size is less than a first threshold data amount. The program accepts a user operation for selecting a data format of the second data to be generated in the conversion process through the operation unit, and accepts a selection of the second format in the third acceptance process. Accordingly, the conversion process is executed by the computer, and the third acceptance when the second threshold data amount larger than the first threshold data amount by a predetermined ratio is equal to or larger than the data size of the first data. In the process, the second format is made unselectable.

  According to the above configuration, when the data size of the first data greatly exceeds the processing capability, the conversion to the second format is not accepted, so that the second data exceeds the processing capability, so that the second data It is possible to suppress the situation where the recording process cannot be executed.

  (6) For example, in the first storage process when the first data is converted into the plurality of partial second data, the program includes a plurality of first identification information for identifying the second data, and a plurality of the plurality of the second data. Second identification information for identifying each partial second data and a total data size of all the partial second data are further stored.

  (7) Preferably, the computer further includes a display unit. The program causes the computer to execute a list display process for causing the display unit to display a list of identification information for identifying data to be recorded, and causes the display unit to display a list in the first reception process. The reverse conversion when a user operation for selecting one of the identification information is accepted through the operation unit, and the second identification information is associated with the first identification information for which selection has been accepted in the first acceptance process. In the process, each of the plurality of partial second data identified by the second identification information is inversely transformed into the inverse transformation program, and the list display process includes the first identification information and the second identification information. Only the first identification information is displayed as a list on the display unit.

  (8) More preferably, the program causes the display unit to display the first identification information and the total data size in association with each other in the list display process.

  According to the above configuration, the second data can be selected as a target for the recording process without making the user aware that the second data is divided into the plurality of partial second data.

  (9) Preferably, in the list display process, the program includes the identification information of the second data that can be reversely converted by the reverse conversion program, and the second data of the second data that cannot be reversely converted by the reverse conversion program. The display mode of the identification information is changed, and in the first reception process, a user operation for selecting only the identification information of the second data that can be reversely converted by the reverse conversion program is received through the operation unit.

  According to the above configuration, the user can recognize that the reverse conversion program cannot be reversely converted and cannot be selected as a recording process target.

  (10) For example, the computer further includes a communication unit. The communication unit can communicate with a server device capable of executing the inverse conversion program. In the capability information acquisition process, the program transmits request information for requesting transmission of the capability information to the server device through the communication unit, and transmits the capability information as a response to the request information through the communication unit. In the reverse conversion process, the conversion instruction information for reverse conversion of the second data is transmitted to the server device through the communication unit, and the reverse conversion data is transmitted as a response to the conversion instruction information. Through the server device.

  However, the inverse conversion program is not limited to the server device, and may be executed by a computer that executes the program according to the present invention.

  (11) For example, the computer further includes a storage unit. The program stores the second data in the storage unit in the first storage process, and performs a user operation for selecting one of the data stored in the storage unit in the first reception process. Accept through.

  However, the storage destination of the second data is not limited to the local memory, and may be a storage server on the Internet.

  (12) For example, the computer further includes a communication unit. In the first data acquisition process, the program receives the first data from the reading device through the communication unit, and in the recording instruction process, the program records the image indicated by the inversely converted data on a sheet.

  However, the computer that executes the program according to the present invention is not limited to being independent from the reading device and the recording device, and the program may be executed by a CPU of a multifunction machine including the reading device and the recording device.

  (13) For example, the program converts the first data into one second data as the first method in the conversion process when it is determined in the first determination process that reverse conversion is possible.

  (14) As an example, the processing capability indicated by the capability information is at least one of the number of pages of the second data that can be inversely converted by the inverse conversion program and the amount of data of the second data that can be inversely converted. Show. Whether the program can perform reverse conversion by comparing the capability information with at least one of the number of pages and the data amount when it is assumed that the first data is converted by the first method in the first determination process. Judge whether or not.

  (1) The control program 65 assumes that all the received JPEG data has been converted into one PDF data, and when the server 70 can reversely convert the PDF data into JPEG data (S31: Yes), the JPEG data Data is converted into PDF data (S32). Further, the control program 65 generates an integrated PDF file name. In addition, the control program 65 assigns the generated integrated PDF file name to the converted PDF data. Further, the control program 65 stores the converted PDF data in the data storage area 62B as an integrated PDF file (S33). Then, the control program 65 adds the integrated PDF file name to the record added to the corresponding file name information. As an example, the corresponding file name record in the second line in FIG. 3A includes the integrated PDF file name “Invoice. PDF”. Even if the server 70 cannot perform reverse conversion (S31: No), the received JPEG data is compressed (S36) so that the data amount is such that the server 70 can perform reverse conversion. ) May be performed.

  (2) The control program 65 generates a JPEG file name when a user operation instructing to store the received JPEG data as a JPEG file is received through the operation unit 54 (S18: JPEG). Further, the control program 65 assigns the generated JPEG file name to the received JPEG data. Further, the control program 65 stores the received JPEG data as a JPEG file in the data storage area 62B (S19). Then, the control program 65 adds the JPEG file name to the record added to the corresponding file name information. As an example, the corresponding file name record in the fourth line in FIG. 3A includes a JPEG file name “Photo.JPEG”.

  (3) When the control program 65 assumes that all received JPEG data has been converted into one PDF data, the server 70 cannot reversely convert the PDF data into JPEG data (S31: No) and has received it. When there are a plurality of JPEG files (S34: Yes), the received plurality of JPEG data is divided into several sets, and each set is converted into one PDF data (S38). In addition, the control program 65 generates a plurality of partial PDF file names. The control program 65 assigns the generated partial PDF file name to each of the converted plurality of PDF data. Further, the control program 65 stores the converted plurality of PDF data in the data storage area 62B as a partial PDF file (S39). Then, the control program 65 adds the partial PDF file name to the record added to the corresponding file name information. Furthermore, the control program 65 generates an integrated PDF file name that integrates a plurality of partial PDF files, and appends it to the record. As an example, the corresponding file name record in the first line in FIG. 3A includes an integrated PDF file name “Estimate.PDF”, partial PDF file names “Estimate-1.PDF”, and “Estimate-2. PDF ".

  (4) When the control program 65 assumes that all received JPEG data has been converted into one PDF data, the server 70 cannot reversely convert the PDF data into JPEG data (S31: No) and has received it. When there is a single JPEG file (S34: No), the received JPEG data is stored in the data storage area 62B as a JPEG file (S37). Further, the control program 65 converts the entire received JPEG data into one PDF data (S32). Then, the control program 65 stores the converted PDF data in the data storage area 62B as an integrated PDF file (S33). As an example, the corresponding file name record in the third line in FIG. 3A includes an integrated PDF file name “manual.PDF” and a JPEG file name “manual.JPEG”.

  That is, the corresponding file name record includes at least one of an integrated PDF file name, a partial PDF file name, and a JPEG file name. More specifically, the corresponding file name record is a record including an integrated PDF file name, a record including a JPEG file name, a record including an integrated PDF file name and a plurality of partial PDF file names, or an integrated PDF file name. And a JPEG file name. The integrated PDF file name is an example of first identification information, and the partial PDF file name is an example of second identification information.

  Note that “store data as a file in the data storage area” is a concept including, for example, inputting a command instructing storage of data as a file, data, and a file name assigned to the data to the OS 64. . The OS 64 that has received the command stores the input data in the data storage area 62B, and registers the input file name in the file system managed by the OS 64. The control program 65 can handle the corresponding file by inputting the file name registered in the file system and an instruction command for the file to the OS 64.

  In FIG. 3A, a file with (real) added to the end of the file name is registered in the file system. That is, the JPEG file name, the partial PDF file name, and the integrated PDF file name generated in (1) or (4) are registered in the file system, so that the control program 65 inputs each file name to the OS 64. A file corresponding to each file name can be handled. On the other hand, since the integrated PDF file name generated in (3) is not registered in the file system, the control program 35 cannot handle the file corresponding to the file name even if the file name is input to the OS 64.

  Note that data registered in the file system as a file by the control program 65 may be referred to as “file” for convenience even before registration in the file system. In other words, the expression “the portable terminal 50 generates a file” is a notation of the concept that “the portable terminal 50 generates data to be registered as a file by the control program 65”. Further, storing the data received by the control program 65 from the multifunction machine 10 or the server 70 as a file in the data storage area 62B is also referred to as “store the received file” for convenience.

  Note that the JPEG file identified by the JPEG file name is an example of first data generated by the multifunction machine 10, for example. The integrated PDF file identified by the integrated PDF file name is an example of second data obtained by converting a JPEG file acquired from the multifunction machine 10 into a single PDF file. The partial PDF file identified by the partial PDF file name is an example of partial second data obtained by converting a JPEG file acquired from the multifunction machine 10 into a plurality of PDF files.

  That is, an integrated PDF file identified by an integrated PDF file name and a plurality of partial PDF files identified by a plurality of partial PDF file names are obtained by converting a JPEG file generated by the multifunction machine 10 into a PDF format. It is common in the point which is obtained, and the concrete conversion method is different. A method for converting a JPEG file into a single integrated PDF file is an example of a first method, and a method for converting a JPEG file into a plurality of partial PDF files is an example of a second method.

  That is, assuming that the same JPEG file format is converted by the first method and the second method, the partial PDF file corresponds to some pages included in the integrated PDF file. In other words, the integrated PDF file can be obtained by integrating a plurality of corresponding partial PDF files. The format conversion is, for example, converting the data format from the first format to the second format or from the second format to the first format without substantially changing the content of the image indicated by the data before conversion. It is processing to do.

  The data storage area 62B can store size information and page information in association with the partial PDF file name. The size information is information indicating the data size of the partial PDF file identified by the corresponding partial PDF file name. The page information is information relating to a page included in the partial PDF file identified by the corresponding partial PDF file name. Specifically, the page information is information indicating a page included in the partial PDF file among the pages of the JPEG file generated by the MFP 10. In other words, the page information is information indicating a page included in the partial PDF file among pages included in the integrated PDF file when it is assumed that the JPEG file is converted into the integrated PDF file by the first method. .

  That is, in the example of FIG. 3A, the partial PDF file identified by the partial PDF file name “Estimate-1.PDF” includes the first to twelfth pages of the corresponding JPEG file or integrated PDF file. Further, the partial PDF file identified by the partial PDF file name “Estimate-2.PDF” includes the 13th to 24th pages of the corresponding JPEG file or integrated PDF file.

  Further, the data storage area 62B stores scanner information and printer information as shown in FIG. 3B, for example. The scanner information includes identification information of a reading device that executes a scanning process in an image reading process to be described later. The printer information includes identification information of a recording apparatus that executes a recording process in an image recording process described later. That is, the portable terminal 50 executes the image reading process using the reading device indicated by the scanner information unless the user explicitly specifies another reading device. Similarly, unless the user explicitly specifies another recording device, the portable terminal 50 executes image recording processing using the recording device indicated by the printer information.

  In the example of FIG. 3B, “MFP-A” that is identification information of the multifunction machine 10 is set in the scanner information and the printer information. For example, the scanner information and the printer information may be arbitrarily changed by the user through the operation unit 54. In the example of FIG. 3B, the same identification information “MFP-A” is set for the scanner information and the printer information, but different identification information may be set for each.

[Server 70]
The server 70 executes processing according to various request information received from the multifunction device 10 or the portable terminal 50. As an example, the server 70 can execute an inverse conversion process for converting a PDF file into an inversely converted file in JPEG format. The inverse conversion process is realized by an inverse conversion program executed by the server 70. As another example, the server 70 transmits capability information regarding the processing capability of the inverse conversion program to the portable terminal 50. The capability information includes, for example, a threshold page number that is the number of pages of a PDF file that can be reversely converted and a first threshold data amount that is the data amount of a PDF file that can be reversely converted.

[Operation of Recording System 100]
The operation of the recording system 100 according to the present embodiment will be described with reference to FIGS. The recording system 100 can asynchronously execute the image reading process shown in FIG. 4 and the image recording process shown in FIG. Hereinafter, the operation of the portable terminal 50 in the image reading process and the image recording process will be mainly described.

[Image reading processing]
The image reading process is a process in which the control program 65 instructs the multifunction machine 10 to generate JPEG data, receives the generated JPEG data, and stores it in the data storage area 62B as a file. As described above, “file” in the present specification is a concept including “data stored as a file by the control program 65”.

  First, the control program 65 of the portable terminal 50 displays a scan instruction screen on the display unit 53 (S11). FIG. 7A is an example of a scan instruction screen. The scan instruction screen shown in FIG. 7A includes a [scanner] icon, an [original size] icon, a [scan image quality] icon, and a [scan] icon. Then, the control program 65 receives a user operation for tapping the position of various icons included in the scan instruction screen through the operation unit 54 (S12).

  The [scanner] icon is an icon for accepting selection of the multi-function device 10 that executes scan processing. In the [scanner] icon, identification information of the selected multifunction machine 10 is displayed. In the example of FIG. 7A, the identification information “MFP-A” indicated by the scanner information is selected. Further, the user can select another reading device with which the portable terminal 50 can communicate by tapping the position of the [scanner] icon.

  The [Original Size] icon indicates the size of the original from which an image is read in the scanning process. In the [Original Size] icon, the size of the selected original is displayed. The [scan image quality] icon indicates the color (for example, “color”, “monochrome”, etc.) of the image read in the scan process. The selected color is displayed in the [Scan Quality] icon. The [Original Size] icon and the [Scan Quality] icon are icons for accepting a user operation for specifying a scan processing execution condition. The user can change the execution condition of the scan process by tapping the position of the [original size] icon and the [scan image quality] icon.

  The [Scan] icon is an icon for accepting a user operation instructing the MFP 10 to execute a scan process. That is, the control program 65 transmits scan instruction information to the multi-function peripheral 10 indicated by the [scanner] icon through the communication unit 55 in response to the position of the [scan] icon being tapped (S12: Yes). The scan instruction information is information that instructs execution of a scan process. The scan instruction information includes setting values indicating execution conditions for scan processing indicated by an [original size] icon, a [scan image quality] icon, and the like.

  Although illustration is omitted, the control program 35 of the multifunction machine 10 receives the scan instruction information from the portable terminal 50 through the communication unit 25. Next, the control program 35 causes the scanner unit 12 to execute scan processing according to the setting value included in the scan instruction information. The scanner unit 12 reads an image recorded on a document set on contact glass or ADF (abbreviation of Auto Document Feeder), and generates image data. Further, the CPU 31 converts the image data generated by the scanner unit 12 into a JPEG file.

  Then, the control program 35 transmits the JPEG file to the portable terminal 50 through the communication unit 25. According to the above processing, there may be one JPEG file generated by the multifunction machine 10 or a plurality of JPEG files. Note that, in a normal usage, the multifunction machine 10 reads an image recorded on one side of a document and generates one JPEG file indicating the image. That is, each JPEG file corresponds to an image recorded on one side of the document. The JPEG file has a different data amount according to the designated image quality of the scan process. The control program 35 transmits all generated JPEG files to the mobile terminal 50 through the communication unit 25.

  Next, the control program 65 of the portable terminal 50 receives the JPEG file from the multifunction device 10 through the communication unit 55 (S13). The JPEG file in the present embodiment is generated by the multi function device 10 according to the procedure described above. However, the acquisition source of the JPEG file is not limited to the following example, and may be received from a storage server (not shown) through the communication unit 55 or taken by a camera (not shown) mounted on the portable terminal 50. There may be. The process of step S13 is an example of a first data acquisition process.

  Next, the control program 65 acquires capability information from the server 70 through the communication unit 55 (S14). Specifically, the control program 65 transmits transmission request information for requesting transmission of capability information to the server 70 through the communication unit 55. Then, the control program 65 receives capability information from the server 70 through the communication unit 55 as a response to the transmission request information. The capability information indicates the processing capability of the inverse conversion program installed in the server 70. The process of step S14 is an example of a capability information acquisition process. In the present embodiment, the following processing will be described on the assumption that capability information indicating that the number of threshold pages = 20 pages and the first threshold data amount = 5 MB has been acquired.

  Next, the control program 65 compares the data amount of the JPEG file received in step S13 with the second threshold data amount (S15). The second threshold data amount is a value larger by a predetermined ratio than the first threshold data amount included in the capability information. Note that the second threshold data amount is estimated by the developer of the control program 65 that the reverse conversion program cannot reversely convert the converted PDF file, no matter how the JPEG file is converted in the data conversion process described later. It is sufficient that the data amount is designed. And the control program 65 displays the format selection screen according to the comparison result of step S15 on the display part 53 (S16, S17).

  In response to the data amount of the JPEG file being less than the second threshold data amount (S15: Yes), the control program 65 displays the format selection screen shown in FIG. 8A on the display unit 53 (S16). . On the other hand, the control program 65 displays the format selection screen shown in FIG. 8B on the display unit 53 in response to the data amount of the JPEG file being equal to or larger than the second threshold data amount (S15: No) ( S17). Then, the control program 65 accepts a user operation for tapping the position of various icons included in the format selection screen through the operation unit 54 (S18). The process of steps S16 to S18 is an example of a third reception process.

  The format selection screen shown in FIGS. 8A and 8B includes a plurality of format icons. The [JPEG] icon is a format icon for accepting an instruction to store the JPEG file received in step S13 in the data storage area 62B without changing the format. The [PDF] icon is a format icon for accepting an instruction to change the JPEG file received in step S13 to the PDF format and store it in the data storage area 62B. On the format selection screen shown in FIG. 8A, all format icons can be selected. On the other hand, in the format selection screen shown in FIG. 8B, the [PDF] icon cannot be selected. That is, the second format cannot be selected in the third reception process when the data amount of the JPEG file is equal to or greater than the second threshold data amount.

  Then, in response to the position of the [JPEG] icon being tapped (S18: JPEG), the control program 65 stores the JPEG file received in step S13 in the data storage area 62B (S19). Further, the control program 65 adds a corresponding file name record including the file name of the JPEG file to the corresponding file name information shown in FIG. The file name of the JPEG file may be automatically determined by the multifunction device 10 or the portable terminal 50, or may be designated by the user through the operation unit 54. The same applies to the file names of the integrated PDF file and the partial PDF file. In this specification, these processes are collectively referred to as “the control program 65 generates a file name”.

  Further, the control program 65 executes conversion processing in response to the position of the [PDF] icon being tapped (S18: PDF) (S20). The conversion process is a process of converting the JPEG file received in step S13 into a PDF file by the first method or the second method described above. Details of the conversion process will be described with reference to FIG.

[Conversion processing]
First, when it is assumed that the entire JPEG file received in step S13 is converted into one integrated PDF file, the control program 65 estimates the number of pages and the data amount of the integrated PDF file. As an example, the control program 65 may consider the number of JPEG files as the number of pages of the integrated PDF file and the data amount of the JPEG file as the data amount of the integrated PDF file. As another example, the control program 65 may estimate the data amount of the integrated PDF file from the data amount of the JPEG file by a predetermined calculation. As yet another example, the control program 65 may actually convert the JPEG file into an integrated PDF file and acquire the data amount of the generated integrated PDF file.

  Then, the control program 65 determines whether or not the reverse conversion program of the server 70 can reverse convert the integrated PDF file based on the capability information acquired in step S14 (S31). Specifically, when the estimated number of pages of the integrated PDF file is less than the threshold page number and the estimated amount of data of the integrated PDF file is less than the first threshold data amount, the control program 65 It is determined that the file can be reversely converted by the reverse conversion program of the server 70 (S31: Yes). On the other hand, when the estimated number of pages of the integrated PDF file is equal to or greater than the threshold number of pages or the estimated amount of data of the integrated PDF file is equal to or greater than the first threshold data amount, The reverse conversion program 70 determines that reverse conversion is not possible (S31: No). The process of step S31 is an example of a first determination process.

  The control program 65 converts the entire JPEG file received in step S13 into one PDF file in response to the reverse conversion program of the server 70 determining that the integrated PDF file can be reversely converted (S31: Yes). Then, an integrated PDF file is generated (S32). Further, the control program 65 generates an integrated PDF file name to be assigned to the generated integrated PDF file, and stores the integrated PDF file in the data storage area 62B (S33). The process of step S33 is an example of a first storage process. Further, the control program 65 adds a corresponding file name record including the integrated PDF file name to the corresponding file name information shown in FIG. In this case, as shown in the second line of FIG. 3A, a corresponding file name record including only the integrated PDF file name is added to the corresponding file name information.

  On the other hand, the control program 65 determines whether or not a plurality of JPEG files have been received in step S13 in response to the reverse conversion program of the server 70 determining that reverse conversion is impossible for the integrated PDF file (S31: No). (S34). The process of step S34 is an example of a second determination process.

  Next, the control program 65 causes the display unit 53 to display a compression confirmation screen in response to determining that the received JPEG file is one (S34: No). FIG. 7B is an example of a compression confirmation screen. The compression confirmation screen shown in FIG. 7B includes a message “The size of the integrated PDF file is too large. Do you want to compress it?”, A [Yes] icon, and a [No] icon. Then, the control program 65 accepts a user operation for tapping the position of various icons included in the compression confirmation screen through the operation unit 54 (S35). The process of step S35 is an example of a second reception process.

  Next, the control program 65 reduces the data amount of the JPEG file by compressing the JPEG file received in Step S13 in response to the position of the [Yes] icon being tapped (S35: Yes). (S36). A well-known compression algorithm can be used for the compression of the JPEG file. Then, the control program 65 converts the compressed JPEG file into an integrated PDF file (S32), generates an integrated PDF file name of the integrated PDF file, and stores the integrated PDF file in the data storage area 62B (S33). ). Since the processing of steps S32 and S33 has already been described, the description thereof will be omitted.

  On the other hand, in response to the position of the [No] icon being tapped (S35: No), the control program 65 generates a JPEG file name of the JPEG file received in step S13, and stores the JPEG file in the data storage area 62B. (S37). The process of step S37 is an example of a second storage process. Further, the control program 65 further executes the processes of steps S32 and S33. Then, the control program 65 adds a corresponding file name record including the file name of the integrated PDF file and the file name of the JPEG file to the corresponding file name information shown in FIG. In this case, as shown in the third line of FIG. 3A, a corresponding file name record including the integrated PDF file name and the JPEG file name is added to the corresponding file name information.

  Furthermore, the control program 65 divides the plurality of JPEG files received in step S13 into several sets in response to determining that there are a plurality of received JPEG files (S34: Yes). A plurality of partial PDF files are generated by converting into one PDF file (S38). Further, the control program 65 generates a partial PDF file name for each of the generated partial PDF files, and stores the partial PDF file in the data storage area 62B (S39). The process of step S39 is an example of a first storage process. Although not shown in the figure, when it is assumed that each set is converted into one PDF file, the JPEG included in each set is set so that the reverse conversion program of the server 70 can reverse-convert the PDF file. Adjust the file page count and data volume. In the adjustment, the capability information acquired in step S14 is referred to.

  Furthermore, the control program 65 generates a corresponding file name record including the file name, size information, page information, and integrated PDF file name of each of the generated partial PDF files, as shown in FIG. Add to name information. In this case, as shown in the first line of FIG. 3A, the integrated PDF file name, a plurality of partial PDF file names, and size information and page information associated with each partial PDF file name are included. The corresponding file name record is added to the corresponding file name information.

  The plurality of partial PDF files generated in step S38 each have the number of pages and the data amount that can be reversely converted by the reverse conversion program of the server 70. That is, each partial PDF file has a page number less than the threshold page and a data amount less than the first threshold data amount. Further, the control program 65 may divide the plurality of JPEG files received in step S13 so that the number of pages of each partial PDF file is equal, or the data amount of each partial PDF file is equalized. You may divide into. However, the number of pages and the data amount of each partial PDF file need not be the same.

[Image recording processing]
The image recording process shown in FIG. 6 is a process for causing the printer unit 11 of the multifunction machine 10 to execute a recording process for recording an image indicated by a file stored in the data storage area 62B on a recording sheet.

  First, the control program 65 of the portable terminal 50 displays a file selection screen on the display unit 53 (S41). FIG. 9 is an example of a file selection screen. The file selection screen shown in FIG. 9 includes a plurality of file icons 111, 112, 113, and 114. Then, the control program 65 receives a user operation for tapping the position of the file icons 111 to 114 through the operation unit 54 (S42). The process of step S41 is an example of a list display process, and the process of step S42 is an example of a first reception process.

  The file icons 111 to 114 correspond to the corresponding file name records shown in FIG. In the file icons 111 to 114, one of the file names included in the corresponding corresponding file name record and the data size of the file specified by the file name are described. The file icon 111 corresponds to the corresponding file name record on the first line, the file icon 112 corresponds to the corresponding file name record on the second line, the file icon 113 corresponds to the corresponding file name record on the third line, and the file icon 114 corresponds to the corresponding file name record on the fourth line.

  When the integrated PDF file name is included in the corresponding file name record corresponding to the file icon in step S41, the control program 65 describes the integrated PDF file name in the file icon. On the other hand, when the integrated PDF file name is not included in the corresponding file name record corresponding to the file icon, the control program 65 describes another file name in the record in the file icon.

  Specifically, the file name described in the file icon 111 is only the integrated PDF file name “estimate.PDF” of the integrated PDF file name and the partial PDF file name. That is, the partial PDF file names “estimate-1.PDF” and “estimate-2.PDF” associated with the integrated PDF file name are not described on the file selection screen. In addition, since the integrated PDF file identified by the integrated PDF file name “estimate.PDF” does not actually exist, the total of the data sizes indicated by a plurality of size information corresponding to the integrated PDF file name “estimate. , “Total data size”) is regarded as the data size of the integrated PDF file, and is described in the file icon 111.

  As another example, the file icon 112 describes the integrated PDF file name “Invoice. PDF”. As another example, in the file icon 113, only the integrated PDF file name “manual.PDF” of the integrated PDF file name and the JPEG file name is described. That is, the JPEG file name “manual.JPEG” associated with the integrated PDF file name is not described on the file selection screen. As yet another example, the file icon 114 describes the JPEG file name “Photo.JPEG”. Since the file identified by the file name described in the file icons 112 to 114 actually exists, the data size of the file is described in the file icons 112 to 114.

  Next, the control program 65 identifies a file to be subjected to recording processing (hereinafter referred to as “target file”) in response to tapping of one position of the file icons 111 to 114. Further, the control program 65 determines the format of the target file (S42). The control program 65 specifies the target file based on the corresponding file name record corresponding to the selected file icon 111 to 114. More specifically, if the JPEG file name is included in the corresponding file name record corresponding to the selected file icon 111 to 114, the control program 65 sets the JPEG file as the target file and includes the JPEG file name. If not, the partial PDF file is the target file. If the partial PDF file name is not included, the integrated PDF file is the target file.

  As an example, when the file icon 111 is selected, the control program 65 selects the partial PDF file name “estimate-1.PDF” from the integrated PDF file name and partial PDF file name included in the corresponding corresponding file name record. The partial PDF file identified by “Estimate-2.PDF” is specified as the target file. As another example, when the file icon 112 is selected, the control program 65 selects an integrated PDF file identified by the integrated PDF file name “delivery form.PDF” included in the corresponding corresponding file name record as the target file. As specified. Further, the control program 65 in these cases determines that the target file is in the PDF format (S42: PDF).

  As another example, when the file icon 113 is selected, the control program 65 is identified by the JPEG file name “Manual.JPEG” among the integrated PDF file name and JPEG file name included in the corresponding file name record. The JPEG file to be processed is specified as the target file. As another example, when the file icon 114 is selected, the control program 65 specifies a JPEG file identified by the JPEG file name “Photo.JPEG” included in the corresponding file name record as a target file. . Further, the control program 65 in these cases determines that the target file is in JPEG format (S42: JPEG).

  Next, in response to determining that the target file is in JPEG format (S42: JPEG), the control program 65 reads the JPEG file name from the corresponding file name record, and selects the JPEG file identified by the JPEG file name. Read from the data storage area 62B through the OS 64. Then, the control program 65 generates recording instruction information for instructing the multifunction device 10 to execute the recording process for the JPEG file, and transmits the generated recording instruction information to the multifunction device 10 through the communication unit 55 (S43). . The recording process is a process in which the multifunction machine 10 records an image on a recording sheet. The recording instruction information in step S43 includes a target file in JPEG format. The process of step S43 is an example of a recording instruction process.

  Although not shown, the control program 35 of the multifunction machine 10 receives the recording instruction information from the portable terminal 50 through the communication unit 25. Then, the control program 35 causes the printer unit 11 to execute a recording process according to the received recording instruction information. Specifically, the control program 35 causes the printer unit 11 to record the image indicated by the JPEG file included in the received recording instruction information on the recording paper.

  On the other hand, the control program 65 reversely converts the PDF file to the server 70 in response to determining that the target file is in the PDF format (S42: PDF) (S44 to S47). That is, the control program 65 transmits the PDF file to the server 70, causes the inverse conversion program of the server 70 to inversely convert the PDF file, and receives the JPEG format inversely converted file generated by the inverse conversion from the server 70. The process of steps S44 to S47 is an example of an inverse conversion process.

  Note that the control program 65 reads the integrated PDF file name from the corresponding file name record in response to the target file being an integrated PDF file (S44: No), and selects the integrated PDF file identified by the integrated PDF file name. Read from the data storage area 62B through the OS 64. Then, the control program 65 transmits the conversion instruction information including the integrated PDF file to the server 70 through the communication unit 55 (S45).

  On the other hand, the control program 65 reads the partial PDF file name from the corresponding file name record in response to the target file being a partial PDF file (S44: Yes), and selects the partial PDF file identified by the partial PDF file name. Read from the data storage area 62B through the OS 64. Then, the control program 65 transmits conversion instruction information including the partial PDF file to the server 70 through the communication unit 55 (S46).

  The conversion instruction information is information for instructing the server 70 to perform an inverse conversion process. In step S46, the control program 65 may transmit conversion instruction information including a plurality of partial PDF files, or may sequentially transmit a plurality of conversion instruction information including one partial PDF file. In any case, the control program 65 instructs the server 70 to perform reverse conversion of all partial PDF files included in one corresponding file name record.

  Although not shown, the server 70 receives conversion request information from the portable terminal 50. Next, the server 70 causes the inverse conversion program to execute an inverse conversion process. The reverse conversion process is a process for converting the PDF file format included in the received conversion request information into a JPEG format to generate an inverse conversion file. Thereby, a plurality of reverse conversion files corresponding to each page included in the PDF file are generated. Then, the server 70 transmits the reverse conversion file generated by the reverse conversion program to the portable terminal 50.

  Next, the control program 65 of the portable terminal 50 receives the reverse conversion file from the server 70 through the communication unit 55 as a response to the conversion request information (S47: Yes). Then, the control program 65 generates recording instruction information for instructing the multifunction device 10 to execute recording processing of the JPEG reverse conversion file, and transmits the generated recording instruction information to the multifunction device 10 through the communication unit 55. (S48). The recording instruction information in step S48 includes a JPEG format reverse conversion file. The process of step S48 is an example of a recording instruction process. The operation of the multifunction machine 10 that has received the recording instruction information is the same as that in step S43.

[Operational effects of this embodiment]
According to the above embodiment, assuming that the JPEG file acquired from the MFP 10 is converted into an integrated PDF file, if the reverse conversion program cannot convert the integrated PDF file, the JPEG file includes a plurality of JPEG files. Converted to partial PDF file. As a result, when a PDF file is selected as a recording process target, each of the plurality of partial PDF files can be inversely converted into an inverse conversion program, and the MFP 10 can execute a recording process for the inversely converted file.

  Further, according to the above-described embodiment, when a JPEG file cannot be divided into a plurality of partial PDF files, the JPEG file is compressed prior to conversion to an integrated PDF file. Thereby, the integrated PDF file which can be reversely converted by the reverse conversion program can be obtained. Note that the control program 65 may convert the JPEG file into an integrated PDF file and compress the integrated PDF file instead of compressing the JPEG file in steps S36 and S32 of FIG.

  However, when a JPEG file is compressed, the image quality of the image indicated by the JPEG file is degraded. Therefore, as shown in step S35 of FIG. 5, it is desirable to let the user select whether to convert the JPEG file into an integrated PDF file even if it is compressed or to store it as it is. In the above embodiment, after the JPEG file is stored in the data storage area 62B, the integrated PDF file obtained by converting the JPEG file is further stored in the data storage area 62B. Steps S32 and S33 may be omitted.

  In the above embodiment, even if the integrated PDF file exceeds the processing capability of the reverse conversion program of the server 70, the PDF file is generated and stored in the data storage area 62B in association with the JPEG file. Yes. For this reason, it is possible to make the multifunction device 10 record the image corresponding to the integrated PDF file using the JPEG file and to use the integrated PDF file from an application or the like operating on the OS 64.

  Further, according to the above embodiment, when the data size of the JPEG file greatly exceeds the processing capability of the reverse conversion program, conversion to a PDF file is not accepted on the format selection screen. Accordingly, it is possible to suppress a situation in which the recording process for the PDF file cannot be executed due to the PDF file exceeding the processing capability of the inverse conversion program.

  In addition, only the integrated PDF file name of the corresponding integrated PDF file name and partial PDF file name is displayed on the file selection screen in the above embodiment. As a result, the user is not made aware that the integrated PDF file is divided into a plurality of partial PDF files and stored. As a result, it is possible to prevent the user from being confused by the existence of a file having substantially the same content. The same applies when the integrated PDF file name and the JPEG file name are associated with each other.

  The control program 65 accepts selection of a PDF file that is not registered in the corresponding file name information (hereinafter referred to as “unregistered PDF file”) on the file selection screen shown in FIG. Also good. That is, the control program 65 may further include a file icon corresponding to the unregistered PDF file on the file selection screen. Then, when the position of the file icon is tapped, the control program 65 may transmit the recording instruction information including the corresponding unregistered PDF file to the multifunction device 10 through the communication unit 55.

  However, the unregistered PDF file may exceed the number of pages or the data size that can be reversely converted by the reverse conversion program. Therefore, the control program 65 can select only the file icon associated with the reverse-convertible PDF file among the file icons displayed in a list on the file selection screen, and the file associated with the PDF file that cannot be reverse-converted. The icon may be disabled. This allows the user to recognize that the reverse conversion program cannot be reversely converted and cannot be selected as the target file.

  Note that, according to the above-described embodiment, the example in which the processes illustrated in FIGS. 4 to 6 are executed by the mobile terminal 50 connected to the multifunction machine 10 and the server 70 through the communication network has been described. However, the form of the recording system 100 is not limited to this. For example, at least one of the portable terminal 50 and the server 70 may be omitted.

  As an example, the inverse conversion program may be executed by the mobile terminal 50. The processing capability in this case varies depending on the clock frequency of the CPU 61 or the storage capacity of the data storage area 62B used as a work area. As another example, the corresponding file name information and file shown in FIG. 3A may be stored in a storage server or the like accessible by the portable terminal 50 through a communication network. As another example, each process of FIGS. 4 to 6 may be executed by the multifunction device 10. That is, the multifunction machine 10 may acquire a JPEG file from the scanner unit 12 connected through the communication bus 33 and cause the printer unit 11 connected through the communication bus 33 to execute a recording process.

  As yet another example, the conversion program installed in the server 70 may execute the process of converting a JPEG file into a PDF file (S32, S38). In this case, the control program 65 of the portable terminal 50 determines whether or not the conversion program of the server 70 can convert the JPEG file received in step S13 into a PDF file. Then, the control program 65 transmits the conversion instruction information to the server 70 through the communication unit 55 in response to determining that conversion is possible. The control program 65 receives the capability information indicating the number of JPEG files and the amount of data that can be converted into a PDF file from the server 70, and compares them with the number of JPEG files and the amount of data received in step S13. It may be determined whether the conversion program of the server 70 can convert the JPEG file into a PDF file.

  The conversion instruction information is information for instructing to convert a JPEG file into a PDF file, and includes a JPEG file to be converted. That is, the conversion instruction information transmitted in step S32 includes all the JPEG files received in step S13. On the other hand, the conversion instruction information transmitted in step S38 includes a set of JPEG files that become one partial PDF file. That is, the control program 65 transmits a plurality of conversion instruction information to the server 70 through the communication unit 55 in step S38.

  The server 70 receives conversion instruction information from the mobile terminal 50. In addition, the server 70 causes the conversion program to convert the JPEG file included in the conversion instruction information into one PDF file. Further, the server 70 transmits the PDF file generated by the conversion program to the portable terminal 50. Then, the control program 65 of the portable terminal 50 receives the PDF file from the server 70 through the communication unit 55.

  In the MFP 10 and the portable terminal 50 according to the embodiment, the CPU 31 and 61 execute various programs stored in the program storage areas 32A and 62A of the storage units 32 and 62, thereby executing the control unit of the present invention. An example in which each process is realized has been described. However, the configuration of the control unit is not limited to this, and part or all of the configuration may be realized by hardware such as an integrated circuit (also referred to as an IC (Integrated Circuit)).

  Furthermore, the present invention may be realized not only as the multifunction device 10 and the portable terminal 50 but also as a program that causes the multifunction device 10 and the portable terminal 50 to execute processing. Then, the program may be provided by being recorded on a non-transitory recording medium. The non-transitory recording medium may include a storage unit mounted on a server that can be connected to the MFP 10 and the portable terminal 50 through a communication network, in addition to a CD-ROM, a DVD-ROM, and the like. And the program memorize | stored in the memory | storage part of the server may be distributed through communication networks, such as the internet, as the information or signal which shows the said program.
