Abstract

PROBLEM TO BE SOLVED: To provide an information processing program and an information processor capable of appropriately preventing occurrence of problem when activating a short-range radio communication to trigger a radio LAN communication with an opposite apparatus during carrying out file conversion using a converter.SOLUTION: When a first radio communication with an external apparatus is started in a short-range radio communication mode during executing a processing to acquire a second data converted from a first data by a converter on a network, the information processing program outputs an instruction to precede the conversion of the first data to the converter. Thus, the converted second data can be swiftly acquired from the converter. Therefore, even when a processing to acquire the second data from a converter is being executed, the connection in a second radio communication is prevented from being maintained for long period. Therefore, little influence is given to the second radio communication to connect another terminal to the external apparatus.

JP 2007-166538 A

  When the file to be printed is a file in a format that cannot be processed by a terminal device, the file to be printed may be converted into a format that can be processed by the terminal device using a conversion device. When the terminal device performs the file conversion, it takes several seconds to several minutes until the terminal device acquires the converted file from the conversion device.

  Since there is a limit to the number of counterpart devices that can be connected at the same time for each communication unit for wireless LAN communication, the printing device cannot perform wireless LAN communication with more terminal devices than can be connected. . Therefore, even if the print data cannot be sent during the file conversion period, the print data can be sent immediately if the connection between the terminal device and the printing device is maintained by wireless LAN communication. There is a possibility that another terminal device in the network cannot be connected to the printing device by wireless LAN communication.

  The present invention has been made in view of the above-described circumstances, and may occur when short-distance wireless communication that triggers wireless LAN communication with a counterpart device is started during file conversion using the conversion device.

An instruction to prioritize the conversion of the first data is output to the conversion device on the condition that the acquisition of the second data is not started from the conversion device that is the output destination of the first data. If acquisition of the second data from the conversion device has not been started, there is a possibility that conversion to the second data has not yet been performed. Therefore, in such a case, since the start of the conversion can be accelerated by outputting a priority instruction, the period until the second data is acquired can be shortened.

  According to the information processing program of claim 3, in addition to the effect of claim 1, the following effect is obtained. On the condition that the conversion device that is the output destination of the first data has not started the conversion from the first data to the second data, an instruction to prioritize the conversion of the first data is output to the conversion device. Therefore, since the start of the conversion to the second data can be accelerated by outputting the priority instruction, the period until the second data is acquired can be shortened.

  According to the information processing program of claim 4, in addition to the effect of any one of claims 1 to 3, the following effect is provided. Since the output of the second data or the third data to the external device is performed by the second wireless communication based on the second wireless information for performing the second wireless communication with the external device without going through the relay device, Even if the relay device capable of performing the second wireless communication with the first wireless information cannot be connected to the external device, the second data or the third data can be output.

  According to the information processing program of the fifth aspect, in addition to the effect produced by the fourth aspect, the following effect is produced. First wireless information for performing second wireless communication with the relay device and third wireless information for setting the external device to perform second wireless communication with the relay device are set in the external device. If they are the same, the second data or the third data is output to the relay device by the second wireless communication based on the first wireless information, and is thereby output to the external device. In such a case, since it is not necessary to perform connection by the second wireless communication based on the second wireless information, it is possible to suppress the vacant device that can be connected to the external device by the second wireless communication at the same time. On the other hand, when the first wireless information and the third wireless information are not the same, an instruction to prioritize the conversion of the first data is output to the conversion device, and the second data or the third data is the second data It is output to the external device by the second wireless communication based on the wireless information. Therefore, since the converted second data can be acquired from the conversion device at an early stage, even when the process of acquiring the second data from the conversion device is being executed, the second wireless communication between the other information processing device and the external device It is possible to connect to the external device by the second wireless communication while suppressing the influence on the connection at.

  According to the information processing program of the eighth aspect, in addition to the effect produced by any one of the fourth to sixth aspects, the following effect is produced. When the acquisition of the second data is completed, if communication with the external device in the second wireless communication based on the second wireless information generated by the external device is not possible, the first wireless communication with the external device is performed. A display for guiding the start of communication again is displayed on the display unit. Therefore, communication with the second wireless communication based on the second wireless information is not possible because another information processing terminal is connected to the external device via the second wireless communication before the acquisition of the second data is completed. Even in this case, it is possible to prompt the user to restart the first wireless communication with the external device.

  According to the information processing program of the ninth aspect, in addition to the effect produced by any one of the first to eighth aspects, the following effect is produced. When the data amount of the first data selected as the processing target data or the second data converted from the first data is equal to or larger than a predetermined threshold, an error display is displayed on the display unit. Therefore, when the amount of data is large and it takes a long time to convert the data, the second data or the third data is not output by the second wireless communication, and can be connected by the second wireless communication at the same time. It is possible to suppress consumption of the device.

  According to the information processing program of the tenth aspect, in addition to the effect produced by any one of the first to ninth aspects, the following effect is produced.

  The AP 50 is a relay device that relays the first Wi-Fi communication. The AP 50 has a broadband router function and can be connected to the Internet 800. The conversion server 200 is a server that converts a first format file (in this embodiment, a PDF format file) uploaded from the terminal 10 into a second format image file different from the first format. Various formats such as JPEG, PNG, GIF, and BMP can be adopted as the second format that is the file format after conversion. The conversion server 200 according to the present embodiment converts a PDF file into a JPEG image file. The conversion server 200 is communicably connected to the terminal 10 via the Internet 800 and the AP 50.

  FIG. 2A is a flowchart showing the file selection process. This process is started when a print menu screen (not shown) is displayed on the LCD 16 when the application 12b is activated. The CPU 11 waits for one menu item to be selected from the print menu screen (S201: No). When photo printing is selected from the menu items that can be selected from the print menu screen (S201: photo printing), the CPU 11 selects a photo image to be printed from photo images stored in the memory card MC. A photo selection screen (not shown) is displayed on the LCD 16, and selection of one or a plurality of photo images to be printed is accepted via the photo selection screen (S205), and this processing is terminated.

  On the other hand, when document printing is selected from the menu items selectable from the print menu screen (S201: document printing), a document file to be printed is selected from the document files stored in the memory card MC. The document file selection screen (not shown) is displayed on the LCD 16 (S202). The document file of the present embodiment is a PDF file (hereinafter referred to as “PDF file”).

  When the document file selection screen is displayed, the CPU 11 waits for the PDF file to be printed to be selected via the document file selection screen (S203: No). When the CPU 11 accepts the selection of the PDF file (S203: Yes), the CPU 11 activates the conversion thread (S204) and ends this process. The conversion thread is a process for causing the conversion server 200 to convert a PDF file selected for printing into a JPEG format image file (hereinafter referred to as “JPEG file”). Hereinafter, conversion from a PDF file to a JPEG file performed by the conversion server 200 may be referred to as “file conversion” or “conversion”.

  FIG. 2B is a flowchart showing the conversion thread described above. The CPU 11 executes the conversion thread in parallel with the print acceptance process described above and other processes such as an NFC print process described later with reference to FIG. The CPU 11 determines whether the processing flag is set to ON (S221). The “processing flag” is a flag indicating whether the PDF file to be printed is being processed by the conversion server 200, that is, whether or not file conversion using the conversion server 200 is being performed. Provided. When the processing flag is set to ON, it indicates that file conversion using the conversion server 200 is being performed. The in-process flag is initialized to off with the activation of the application 12b.

  The CPU 11 transmits the PDF file that has received the selection as the print target to the AP 50 through the first Wi-Fi communication, and uploads it to the conversion server 200 via the Internet 800 (S222). When the PDF file is uploaded, the conversion server 200 starts a process for converting the PDF file. The conversion server 200 assigns a file ID to the uploaded file, analyzes the file, and acquires the number of pages constituting the PDF file to be printed. The file ID is identification information for individually specifying the files to be converted by the conversion server 200.

  The CPU 11 acquires the file ID assigned to the uploaded PDF file and the number of pages of the PDF file from the conversion server 200 (S223, S224). The CPU 11 acquires these information by requesting the conversion server 200 to acquire the file ID and the number of pages.

  The CPU 11 waits until a predetermined time, for example, 5 seconds elapses after uploading the PDF file (S225: No). When the CPU 11 determines that the predetermined time has elapsed (S225: Yes), the CPU 11 inquires of the conversion server 200 whether the conversion of the corresponding file is completed using the acquired file ID (S226). The CPU 11 determines whether the file conversion is completed based on a reply from the conversion server 200 in response to the inquiry (S227). When the CPU 11 determines that the file conversion has not been completed (S227: No), the CPU 11 shifts the process to S225 and waits for a predetermined time (for example, 5 seconds) to elapse.

  On the other hand, when the CPU 11 determines that the file conversion is completed (S227: Yes), the CPU 11 sets the download flag to ON (S228). The “download flag” is a flag indicating whether or not a JPEG file is being downloaded from the conversion server 200, and is provided in the RAM 13. When the download flag is set to ON, it indicates that the JPEG file is being downloaded. The download flag is initialized to off with the activation of the application 12b.

  The CPU 11 starts downloading the JPEG file (S229). Specifically, the CPU 11 starts downloading the JPEG file by transmitting the file ID and the download request acquired in S223 to the conversion server 200. As a result of the process of S229, the conversion server 200 sequentially transmits the JPEG file obtained by file conversion from the PDF file uploaded in S222 to the terminal 10 page by page. The terminal 10 sequentially acquires JPEG files converted from the PDF file selected as the print target.

  The CPU 11 waits until the download is completed (S230: No). When the CPU 11 determines that the download is complete (S230: Yes), the CPU 11 sets the processing flag and the download flag to off (S231, S232), and ends this process.

  FIG. 3 is a flowchart showing the NFC printing process. This process is started when the application 12b is activated. The CPU 11 executes the NFC print process in parallel with other processes such as the print acceptance process and the conversion thread described above. The CPU 11 waits for reception of an NFC event (S301: No). The NFC event is an event that the OS 12a notifies the application 12b when the terminal 10 (the near field communication unit 22) detects a device (hereinafter referred to as “NFC device”) such as the MFP 100 that is a communication partner of NFC communication. is there. As the terminal 10 detects the NFC device, NFC communication is established and started between the terminal 10 and the detected NFC device.

  When the CPU 11 determines that an NFC event has been received (301: Yes), the CPU 11 requests the MFP 100 for the SSID by NFC communication, and thereby acquires the SSID from the MFP 100 by NFC communication (S302). More specifically, in S302, the CPU 11 detects two types of SSIDs, specifically, the SSID of the AP used by the MFP 100 as a relay device (that is, the infrastructure SSID), and that the MFP 100 detects the terminal 10 as an NFC device. Acquire the SSID issued along with this. The latter SSID is a so-called one-time SSID that permits connection with the wireless communication unit 123 on the condition of one-time use. Hereinafter, the latter SSID is referred to as “direct SSID”.

  When photo printing is selected from the print menu screen (S303: photo printing), the CPU 11 executes the conventional processing to cause the MFP 100 to print the photo image selected as the printing target (S314), and performs this processing. finish. Specifically, as a conventional process, the CPU 11 first establishes the second Wi-Fi communication between the terminal 10 and the MFP 100 by setting the direct SSID acquired in S <b> 302, and sets the print target. Print data is generated from the JPEG file (here, a photo image) and the print settings set in the application 12b. Next, the CPU 11 transmits the generated print data and a print instruction to the MFP 100 through the second Wi-Fi communication.

  On the other hand, when document printing is selected from the print menu screen (S303: document printing), the CPU 11 determines whether a document file to be printed (in this embodiment, a PDF file) has been selected (S304). . If the CPU 11 determines that the PDF file to be printed has not been selected (S304: No), the CPU 11 displays an error display notifying that the file to be printed has not been selected on the LCD 16 (S315). The process ends.

  When the CPU 11 determines that the PDF file to be printed has been selected (S304: Yes), the CPU 11 determines whether the PDF file to be printed is being processed by the conversion server 200 (S305). The CPU 11 performs the determination in S305 according to the content of the processing flag. Specifically, when the processing flag is set to ON, the CPU 11 affirms the determination in S305. On the other hand, when the processing flag is set to OFF, the CPU 11 denies the determination of S305.

  If the CPU 11 denies the determination in S305 (S305: No), it indicates that the PDF file to be printed is not being processed by the conversion server 200, that is, the download of the converted JPEG file has been completed. Therefore, in such a case, the CPU 11 causes the MFP 100 to print the downloaded JPEG file by executing the conventional processing (S314), and ends this processing.

  On the other hand, when the CPU 11 affirms the determination in S305, that is, when the PDF file to be printed is being processed by the conversion server 200 (S305: Yes), the CPU 11 determines the number of pages constituting the PDF file to be printed, That is, it is determined whether the number of pages acquired in S224 is equal to or greater than a predetermined threshold P (for example, P = 20) (S306). When the CPU 11 determines that the number of pages is equal to or greater than the threshold value P (S306: Yes), the CPU 11 displays an error display notifying that printing cannot be performed during file conversion on the LCD 16 (S315), and ends this processing. .

  When the CPU 11 determines that the number of pages is less than the threshold P (S306: No), the CPU 11 determines whether the infrastructure SSID set by the application 12b is the same as the infrastructure SSID used by the MFP 100 ( S307). Specifically, the CPU 11 determines whether the infrastructure SSID stored in the application storage area 12c is the same as the infrastructure SSID acquired in S302.

  When the CPU 11 determines that the infrastructure SSIDs are different from each other (S307: No), the CPU 11 performs processing for establishing the second Wi-Fi communication between the terminal 10 and the MFP 100 ( A handover process is executed (S308). Specifically, the CPU 11 establishes the second Wi-Fi communication by setting the direct SSID acquired in S302.

  The CPU 11 determines whether the download of the JPEG file has been started (S309). The CPU 11 performs the determination in S309 according to the content of the download flag. Specifically, when the download flag is set to ON, the CPU 11 affirms the determination in S309 regardless of the content of the processing flag. On the other hand, when the download flag is set to OFF, the CPU 11 denies the determination in S309.

  When the CPU 11 denies the determination of S309, that is, when the download of the JPEG file has not yet started (S309: No), the CPU 11 has held another terminal over the MFP 100, or more specifically, Thus, it is determined whether NFC communication has been established between the two devices (S310). When NFC communication is established between the two apparatuses due to the other terminal being held over MFP 100, MFP 100 notifies terminal 10 accordingly. Therefore, in S310, the determination in S310 is performed depending on whether or not the notification is received from the MFP 100. Specifically, when CPU 11 receives a notification that NFC communication has been established from MFP 100, CPU 11 affirms the determination in S310. On the other hand, if the CPU 11 has not received notification from the MFP 100 that NFC communication has been established, the determination in S310 is denied.

  When CPU11 denies determination of S310 (S310: No), CPU11 transfers a process to S309. On the other hand, when the CPU 11 affirms the determination in S310, that is, when another terminal is held over the MFP 100 (S310: Yes), the CPU 11 issues a conversion priority instruction to the conversion server 200 (S311). Specifically, the CPU 11 transmits the file ID acquired in S223 and the information indicating the conversion priority as a priority instruction to the AP 50 by the first Wi-Fi communication, and transmits it to the conversion server 200 via the Internet 800. Send. When the conversion server 200 receives the priority instruction of S311, the conversion server 200 moves the processing order of the PDF file corresponding to the file ID included in the priority instruction to the head of the file group waiting for processing, and the processing of the PDF file is performed. Make sure that it is given priority. If conversion server 200 is already executing conversion of the PDF file corresponding to the file ID included in the received priority instruction, the conversion being executed is continued.

  After the process of S311, the CPU 11 determines whether the download of the JPEG file has been completed (S312). The CPU 11 makes the determination in S312 according to the contents of the processing flag. Specifically, when the processing flag is set to ON, the CPU 11 denies the determination in S312. On the other hand, when the processing flag is set to OFF, the CPU 11 affirms the determination in S312. When the CPU 11 denies the determination of S312, that is, when the download of the JPEG file has not yet been completed (S312: No), the CPU 11 waits until the download is completed.

  On the other hand, if the CPU 11 determines in S312 that the download has been completed (S312: Yes), the CPU 11 executes a print execution process (S313) and ends this process. When the CPU 11 determines that the download of the JPEG file has started in S309 (S309: Yes), the CPU 11 executes the process of S312.

  Specifically, in step S313, the CPU 11 generates print data from the downloaded JPEG file and the print settings set in the application 12b, and transmits the generated print data and a print instruction to the MFP 100. The MFP 100 uses the printing function to execute printing according to the received print data, thereby printing an image according to the converted JPEG file, that is, an image according to the PDF file selected as the print target. Printed on paper. Note that when the second Wi-Fi communication is established between the terminal 10 and the MFP 100, the print data is transmitted from the terminal 10 to the MFP 100 by the second Wi-Fi communication.

  In S307, when the CPU 11 determines that the infrastructure SSID set by the application 12b is the same as the infrastructure SSID acquired in S302 (S307: Yes), the CPU 11 shifts the processing to S312. When the CPU 11 affirms the determination in S307, the first Wi-Fi communication via the AP 50 has already been established between the terminal 10 and the MFP 100. Therefore, when the CPU 11 determines that the download has been completed after affirming the determination in S307 (S312: Yes), the CPU 11 transmits the print data through the first Wi-Fi communication via the AP 50 to perform the process of S313. Execute the process. In such a case, it is not necessary to establish the second Wi-Fi communication, so that it is possible to prevent the MFP 100 from consuming available devices that can be connected by Wi-Fi communication at the same time.

  According to the first embodiment, when NFC communication is established between the terminal 10 and the MFP 100 in a situation where a PDF file to be printed is being processed by the conversion server 200, the conversion priority instruction is converted. It is transmitted to the server 200. As a result, the conversion server 200 moves to the top of the processing order of the PDF file corresponding to the file ID included in the priority instruction and the file group waiting for processing, so that the start of file conversion can be accelerated.

  When the start of file conversion is accelerated, the JPEG file is downloaded earlier than originally scheduled, so that the completion of transmission of print data by the second Wi-Fi communication is also accelerated. Therefore, in the situation where the PDF file to be printed is being processed by the conversion server 200, the connection by the second Wi-Fi communication is long-term based on the establishment of NFC communication between the terminal 10 and the MFP 100. It can suppress that it is maintained over. Thus, since one of the connectable numbers of Wi-Fi communication in MFP 100 is not occupied for a long period of time, it is possible to suppress a situation in which another terminal cannot establish second Wi-Fi communication with MFP 100. Further, since an error does not occur as in the prior art, it is not necessary to hold the terminal 10 over the MFP 100 again, which is convenient.

  In particular, the fact that another terminal is held over MFP 100 is used as the transmission condition for the conversion priority instruction, so that the other terminal that is ready to transmit the print data establishes the second Wi-Fi communication with MFP 100. The situation where it cannot be performed can be suitably suppressed. Further, the transmission condition of the conversion priority instruction includes that the download of the JPEG file has not started. If the download of the JPEG file from the conversion server 200 has not started, there is a possibility that the conversion to the JPEG file has not yet been performed. Therefore, when the download of the JPEG file has not started, the start of file conversion can be effectively accelerated by outputting a conversion priority instruction.

  As the number of pages constituting the PDF file to be printed increases, the time required for file conversion in the conversion server 200, that is, the time until a JPEG file can be prepared becomes longer. On the other hand, according to S306, if the number of pages is greater than or equal to the threshold value P, an error occurs and the second Wi-Fi communication is not established. In this respect as well, it is possible to suppress the terminal 10 that cannot prepare the JPEG file from interfering with the second Wi-Fi communication between the other terminal and the MFP 100 for a long period of time.

  Next, a second embodiment will be described with reference to FIG. In the first embodiment, when NFC communication is established between the terminal 10 and the MFP 100 in a situation where a PDF file to be printed is being processed by the conversion server 200, the second file established between these devices is used. After the Wi-Fi communication is established, a priority instruction is transmitted to the conversion server 200. In the second embodiment, after the priority instruction is transmitted to the conversion server 200, the second Wi-Fi communication is established between the terminal 10 and the MFP 100 on the condition that the download of the JPEG file is completed. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, the configuration unique to the second embodiment will be mainly described.

  FIG. 4 is a flowchart showing the NFC printing process of the second embodiment. This process is a process executed by the CPU 11 of the terminal 10 in accordance with the application 12b of the second embodiment. Like the first embodiment, the application 12b Starts when is started. In this process, when the CPU 11 denies the determination of S307 (S307: No), the CPU 11 executes the determination of S309 without performing the handover process.

  After the process of S311, the CPU 11 determines whether the download of the JPEG file has been completed as in S312 (S401). The CPU 11 waits for completion of downloading of the JPEG file (S401: No). When the download is completed (S401: Yes), the CPU 11 determines whether the direct SSID acquired in S302 is still valid (S402). Specifically, the CPU 11 inquires of the MFP 100 whether the target direct SSID is valid, and makes a determination in S402 based on a reply from the MFP 100 in response to the inquiry.

  When the CPU 11 determines that the target direct SSID is valid (S402: Yes), the CPU 11 executes a handover process in the same manner as S308 (S403), and the process proceeds to S313. On the other hand, when the CPU 11 determines that the target direct SSID is not valid, that is, invalid (S402: No), the CPU 11 displays on the LCD 16 a reconnection guidance that prompts the user to hold the terminal 10 over the MFP 100 again. (S404), the process ends.

  According to the second embodiment, when the download of the JPEG file is completed, it is determined whether or not the direct SSID acquired from the MFP 100 is valid, and if it is invalid, the reconnection guidance is displayed. Therefore, even if the terminal 10 cannot establish the Wi-Fi communication with the MFP 100 due to the establishment of the Wi-Fi communication between the other terminal and the MFP 100 before the download of the JPEG file is completed, the printing can be performed. This makes it possible for the user to grasp the matters necessary for realizing the above.

  Next, a third embodiment will be described with reference to FIG. In the first embodiment, when a PDF file to be printed is being processed by the conversion server 200 and NFC communication is established between the terminal 10 and the MFP 100, downloading of the JPEG file is started. The CPU 11 is configured to transmit a conversion priority instruction to the conversion server 200 on the condition that there is not. In the third embodiment, the condition before the file conversion is started by the conversion server 200 is set as the transmission condition of the priority instruction. In 3rd Embodiment, the same code | symbol is attached | subjected to the part same as 1st Embodiment, and the description is abbreviate | omitted. Hereinafter, the configuration unique to the third embodiment will be mainly described.

  FIG. 5 is a flowchart showing the NFC printing process of the third embodiment. This process is a process executed by the CPU 11 of the terminal 10 in accordance with the application 12b of the third embodiment. Like the first embodiment, the application 12b Starts when is started. In this process, the CPU 11 determines whether file conversion is started in the conversion server 200 after the process of S308 (S501).

  In this embodiment, the conversion server 200 is configured to notify the transmission source terminal of the file to be converted that the file conversion has started when starting the file conversion. The CPU 11 performs the determination in S501 depending on whether or not the notification is received. Specifically, when the notification indicating that the file conversion has started is received from the conversion server 200, the CPU 11 affirms the determination of S501, while the notification indicating that the file conversion has started is received from the conversion server. When not receiving from 200, CPU11 denies determination of S501.

  When CPU11 affirms the judgment of S501 (S501: Yes), CPU11 transfers a process to S312. On the other hand, if the CPU 11 denies the determination in S501, that is, if the file conversion has not yet started in the conversion server 200 (S501: No), the CPU 11 proceeds to S310.

  According to the third embodiment, the fact that the file conversion is not started in the conversion server 200 is used as the transmission condition for the conversion priority instruction, so the start of the file conversion can be effectively accelerated.
