  According to the technique of Patent Document 1, data of a terminal is transmitted to the printing apparatus using communication based on the wireless LAN standard (hereinafter referred to as “wireless LAN communication”) by bringing the terminal closer to the printing apparatus, and based on the data Printing can be performed by a printing device. Normally, there is a limit to the number of counterpart devices that can be connected to one wireless LAN communication unit at the same time. That is, the number of counterpart devices to which the communication unit can be connected is limited to the number of storable communication settings (SSID (Service Set Identifier)) for wireless LAN communication. Therefore, if wireless LAN communication is established with the number of counterpart devices to which the communication unit can be connected, wireless LAN communication cannot be performed with other terminals until any communication is disconnected. . Therefore, when the number of terminals that have already established wireless LAN communication with the communication unit for wireless LAN communication has already reached the number that can be connected, even if another terminal is brought closer to the printing apparatus, the other terminal Since the wireless LAN communication cannot be performed with the communication unit, a communication error has to be made. When a communication error occurs, it is necessary to bring the terminal close to the printing apparatus again, which is complicated.

  The present invention has been made in view of the above-described circumstances, and a function execution device and a function in which each terminal can easily use the function processing in a situation where various terminals use the function processing using short-range wireless communication. An object is to provide an execution program.

  In order to achieve this object, the function execution device of the present invention communicates with an external device using a first communication unit that communicates with an external device using a short-range wireless communication method and a wireless communication method different from the short-range wireless communication method.

Determine if there is From the start of communication via the first communication unit with the first determination unit and the first device until the execution instruction for causing the function unit to execute the function processing is received from the first device. When communication via the first communication unit and a second device, which is an external device different from the first device, is started, the second wireless information is different from the first information based on the start of the communication. A second generation unit that generates information; a transmission unit that transmits the wireless information generated by the first generation unit or the second generation unit to a corresponding external device; and the second generation unit A setting for setting storage control means for storing second information in the storage section and the wireless information generated by the first generation means or the second generation means for performing communication via the second communication section. Means and the setting means The second communication unit using the set wireless information with the external device to which the set wireless information has been transmitted by the transmission means as a counterpart device based on the setting of the wireless information by An instruction receiving means for receiving the execution instruction from the counterpart apparatus by communication via the communication apparatus, and when the execution instruction is received from the counterpart apparatus by the instruction reception means, the counterpart apparatus by communication via the second communication section.

If communication via the first communication unit and the second device, which is an external device different from the first device, is started during this period, the second information that is wireless information is based on the start of the communication. Generated and stored in the storage unit. When the second information is generated and the first device is executing conversion using the conversion unit, the first information set prior to the second information is used to communicate with the first device. The second information stored in the storage unit is set instead of the set first information on condition that the communication via the second communication unit is performed and the reception of the information related to the execution of the function processing is completed.

In the present embodiment, the communication performed by the wireless communication unit 23 is wireless communication using a wireless LAN compliant with the IEEE802.11b / g standard. In the present embodiment, the wireless communication unit 23 communicates with the terminal 100 having the wireless communication unit 123 in either an infrastructure mode via an access point that is a relay device or an ad hoc mode that is a direct connection. -Connected by wireless communication based on the Fi (registered trademark) standard (hereinafter referred to as "Wi-Fi communication"). In particular, when the NFC communication with the terminal 100 is started, the MFP 10 according to the present embodiment is triggered by the start of the NFC communication as a trigger to establish a Wi- Establish Fi communication.

  The terminal 100 is configured as a terminal such as a smartphone. The terminal 100 includes a CPU 111, a flash memory 112, a RAM 113, an operation key 115, an LCD 116, a touch panel 117, a memory card interface (memory card I / F) 118, a voice input / output unit 119, a telephone network communication unit 120, and a short-range communication unit. 122, a wireless communication unit 123 is provided. These units are connected to each other via a bus line 124.

  The CPU 111 controls each unit connected to the bus line 124 according to a fixed value, a program, or the like stored in the flash memory 112 or the like. The flash memory 112 is a rewritable nonvolatile memory. The flash memory 112 stores an operating system 112a (hereinafter referred to as OS 112a) and a device control application 112b. The OS 112a is basic software for realizing the standard functions of the terminal 100. In this embodiment, an Android (registered trademark) OS is employed as the OS 112a.

  The device control application (hereinafter referred to as “device control application”) 112 b is an application provided by a vendor of a device such as the MFP 10, and is installed in the terminal 100 by the user and allows the terminal 100 to use the device. For example, it is possible to directly use the printing function or scanning function of the device from the terminal 100 without going through a personal computer (PC).

  When NFC communication with the MFP 10 is started, the terminal 100 equipped with the device control application 112b establishes Wi-Fi communication in the ad hoc mode with the MFP 10 using the start of the NFC communication as a trigger, Using the established Wi-Fi communication, image data for printing is transmitted to the MFP 10 and an image based on the image data is printed by the printer unit 19.

  The operation key 115 is a mechanical key for inputting an instruction or the like to the terminal 100, and is provided on the housing of the terminal 100, for example. The LCD 116 is a liquid crystal display device that displays various screens.

Similar to the wireless communication unit 23, the wireless communication unit 123 is an interface for wireless LAN communication. The wireless communication unit 123 is connected to an access point (AP) 50, which is a relay device having a broadband router function, by Wi-Fi communication. Further, as described above, the wireless communication unit 123 can directly perform Wi-Fi communication with the MFP 10 in the ad hoc mode.

  The AP 50 is a relay device that relays Wi-Fi communication. The AP 50 has a broadband router function and can connect to the Internet 800. Therefore, the terminal 100 is connected to the conversion server 200 on the Internet 800 through the AP 50 so as to be communicable. The conversion server 200 is a server that converts processing target data uploaded from the terminal 100 into image data in a predetermined format. Various formats such as JPEG, PNG, GIF, and BMP can be adopted as the format of the converted image data.

  FIG. 2 is a flowchart showing the SSID generation process executed by the CPU 11 of the MFP 10 according to the control program 12a. This process is a process in which the MFP 10 generates an SSID for performing Wi-Fi communication with the terminal 100 in the ad hoc mode based on the start of NFC communication between the terminal 100 capable of performing NFC communication and the MFP 10. It is. In the present embodiment, the SSID generated in this process is a so-called one-time SSID that permits establishment of Wi-Fi communication on the condition of one-time use. This process is started when the CPU 11 detects the terminal 100 via NFC, that is, when NFC communication is started between both devices.

  The CPU 11 determines whether the next standby flag is set to ON (S201). The “next standby flag” is a period for waiting for the start of NFC communication with another terminal 100 that may be the target of switching the execution order of print processing in NFC printing after NFC communication is started with one terminal 100. It is a flag indicating that it is in the middle, and is provided in the RAM 13. When the next standby flag is set to ON, it indicates that it is during a period of waiting for the start of NFC communication with another terminal 100.

  The next terminal flag is set to OFF when this process starts, and is set to ON when NFC communication is started with the terminal 100 that satisfies a predetermined condition. The “predetermined condition” is a case where the terminal 100 is converting the processing target data using the conversion server 200 and the number of pages of the processing target data is equal to or greater than a predetermined threshold P. The next standby flag set to ON is set to OFF in response to receiving a print instruction from the terminal 100 related to turning on the next standby flag. In other words, the period during which the next standby flag is on, that is, the period for waiting for the start of NFC communication with another terminal 100 that can change the execution order of the print processing in NFC printing, is the terminal 100 that satisfies the predetermined condition. This is a period from when the NFC communication is started between the MFP 10 and the MFP 10 to before the MFP 10 receives a print instruction from the terminal 100.

  When the CPU 11 determines that the next standby flag is off (S201: No), the CPU 11 acquires the NDEF data received from the terminal 100 by NFC communication (S202). “NDEF data” is information according to the data format of NFC communication. In S202, the NDEF data acquired by the CPU 11 is generated by the terminal 100 based on the start of NFC communication with the MFP 10, and the conversion flag, the number of converted pages, and the terminal information are displayed. Including.

  The “in-conversion flag” is a flag indicating whether or not the terminal 100 is executing conversion of processing target data using the conversion server 200. When the conversion flag is set to ON, it indicates that the conversion is being executed. On the other hand, when the conversion flag is set to OFF, it indicates that the conversion is not being executed. “Conversion in progress” or “Conversion in progress” means a period from when the terminal 100 uploads the processing target data to the conversion server 200 until the download of the image data obtained by the conversion in the conversion server 200 is completed. And

  The “number of conversion pages” is data indicating the number of pages of processing target data that is the original data of conversion performed by the conversion server 200. When the processing target data is uploaded, the conversion server 200 analyzes the processing target data and transmits the number of conversion pages obtained as a result of the analysis to the terminal 100. Therefore, the terminal 100 embeds the number of converted pages received from the conversion server 200 in the NDEF data and transmits it to the MFP 10. Note that the terminal 100 may be configured to embed the number of converted pages acquired by analyzing the processing target data in its own device in the NDEF data and transmit it to the MFP 10. “Terminal information” is information that can identify the terminal 100. As the terminal information, for example, an individual number assigned to each terminal 100, an IP address, a MAC address, or the like can be used.

  The CPU 11 acquires a conversion flag, the number of converted pages, and terminal information from the acquired NDEF data (S203). The CPU 11 stores the acquired terminal information in a predetermined area of the RAM 13 (S204). Next, the CPU 11 generates an SSID and a password for performing Wi-Fi communication with the terminal 100 in the ad hoc mode (S205). The CPU 11 determines whether or not the in-conversion flag acquired in S203 is set to ON (S206). If the CPU 11 determines that the conversion flag is set to ON (S206: Yes), the CPU 11 has the number of converted pages acquired in S203 equal to or greater than a predetermined threshold P (for example, P = 10). Is determined (S207).

  When the CPU 11 determines that the number of converted pages is equal to or greater than the threshold value P (S207: Yes), the CPU 11 activates a built-in timer (not shown) and starts time measurement using the timer (S208). The CPU 11 sets the next standby flag to ON (S209). The CPU 11 sets the SSID generated in S205 as the low priority SSID (S210). The CPU 11 stores the generated SSID and password in the RAM 13 (S211), and the process proceeds to S212.

  On the other hand, if the CPU 11 determines that the conversion flag is not set to ON (S206: No), or if the CPU 11 determines that the conversion page number is not equal to or greater than the threshold value P (S207: No), the CPU 11 Then, the next standby flag is set to OFF (S215). The CPU 11 sets the SSID generated in S205 as the high priority SSID (S216), and shifts the processing to S212.

  According to the processing of S206, S207, and S216, when the terminal 100 is not executing conversion of the processing target data using the conversion server 200, or the conversion is being executed, the number of conversion pages is the threshold value. When it is less than P, the SSID generated based on the start of NFC communication with the terminal 100 is treated as a high priority SSID. That is, in a situation where conversion is not performed or the time required for conversion is estimated to be relatively short, the CPU 11 treats the generated SSID as a high priority SSID.

  On the other hand, according to the processing of S206, S207, and S210, the terminal 100 is executing conversion of processing target data using the conversion server 200, and the number of pages of image data obtained by the conversion is the threshold value P. In the case described above, the SSID generated based on the start of NFC communication with the terminal 100 is handled as a low priority SSID. That is, in a situation where it is estimated that the time required for conversion is relatively long, the CPU 11 treats the generated SSID as a low priority SSID.

  As will be described in detail later, the high priority SSID is preferentially set in order to establish Wi-Fi communication, whereas the low priority SSID is possibly generated by a high priority SSID generated later. Settings may be postponed. Therefore, when the SSID generated for the terminal 100 for which NFC communication has been started is a low priority SSID, the setting for performing Wi-Fi communication is set in the terminal 100 for which NFC communication has been started thereafter. It may be performed after the setting of the SSID generated.

  In S212, the CPU 11 embeds the generated SSID and password in the NDEF data. The CPU 11 transmits NDEF data including the SSID and the password to the terminal 100 by NFC communication (S213). When receiving the NDEF data transmitted in S213, the terminal 100 that is the communication partner of the NFC communication sets the SSID included in the NDEF data. Then, the terminal 100 transmits the password included in the received NDEF data to the MFP 10 on condition that the processing target data using the conversion server 200 is completed. The above condition includes a case where conversion of processing data is unnecessary.

  The CPU 11 sets the generated SSID (S214) and ends this process. When the SSID is set in S214, when a password corresponding to the set SSID is received from the destination terminal 100 that has transmitted the NDEF data in S212, the terminal 100 and the MFP 10 are connected by Wi-Fi communication. Connected, thereby establishing Wi-Fi communication between both devices.

  In S201, when the CPU 11 determines that the next standby flag is on (S201: Yes), the next terminal flag is set to on. The “next terminal flag” is a period for waiting for the start of NFC communication with another terminal 100 that can change the execution order of print processing in NFC printing after NFC communication is started with one terminal 100. A flag indicating whether or not NFC communication has started with another terminal 100 is provided in the RAM 13. When the next terminal flag is set to ON, it indicates that NFC communication has started with another terminal 100 during the period. The next terminal flag is set to OFF with the start of this process.

  The CPU 11 acquires NDEF data received from the terminal 100 by NFC communication that has triggered the start of this process (S218). In step S218, the NDEF data acquired by the CPU 11 is generated based on the start of NFC communication with the MFP 10 by the terminal 100, similarly to the NDEF data acquired in step S202 described above. The CPU 11 acquires a conversion flag, the number of converted pages, and terminal information from the acquired NDEF data (S219).

  The CPU 11 has a terminal 100 (hereinafter referred to as “next terminal 100”) that is the partner of NFC communication that has triggered the start of this process, and a next standby flag that indicates that NFC communication has started before the next terminal 100. It is determined whether the terminal 100 related to ON (hereinafter referred to as “the previous terminal 100”) is the same terminal (S220). Specifically, the CPU 11 compares the terminal information acquired in S219 with the terminal information stored in the RAM 13 in S204, and determines that they are the same terminal if they match. When the CPU 11 determines that the next terminal 100 and the previous terminal 100 are not the same terminal (S220: No), the CPU 11 generates an SSID and a password for performing Wi-Fi communication with the terminal 100 in the ad hoc mode. (S221).

  Next, the CPU 11 determines whether or not a predetermined time has elapsed since the time measurement was started in S208 (S222). In the present embodiment, the “predetermined time” used as the threshold value in the determination in S222 is determined by the CPU 11 according to the number of converted pages corresponding to the previous terminal 100, that is, the number of converted pages acquired in S203. Specifically, the CPU 11 estimates the time required for the conversion to be completed based on the number of conversion pages corresponding to the previous terminal, and some percentage of the estimated time (for example, the estimated time) 80% of the time) is determined as “predetermined time”. That is, in the present embodiment, the “predetermined time” is longer as the number of converted pages corresponding to the previous terminal 100 is larger.

  When the CPU 11 determines that the predetermined time has not yet elapsed (S222: No), the CPU 11 determines whether or not the conversion flag acquired in S219 is set to ON (S223). If the CPU 11 determines that the conversion flag is set to ON (S223: Yes), the CPU 11 has the number of converted pages acquired in S219 equal to or greater than a predetermined threshold P (for example, P = 10). Is determined (S224). Note that the threshold P used for the determination in S224 and the threshold P used for the determination in S207 may be the same value or different values.

  When the CPU 11 determines that the number of converted pages is equal to or greater than the threshold P (S224: Yes), the CPU 11 sets the SSID generated in S221 as the low priority SSID (S225). The CPU 11 stores the generated SSID and password in the RAM 13 (S226), and the process proceeds to S227. On the other hand, if the CPU 11 determines that the conversion flag is not set to ON (S223: No), or if the CPU 11 determines that the conversion page number is not equal to or greater than the predetermined value P (S224: No), the CPU 11 Uses the SSID generated in S221 as the high priority SSID (S229), and shifts the processing to S227.

  According to the processes of S223, S224, and S229, if the SSID generated for the next terminal 100 does not convert the processing target data that the next terminal 100 has, or the time required for the conversion is relatively short In the estimated situation, it is treated as a high priority SSID. On the other hand, according to the processes of S223, S224, and S225, the SSID generated for the next terminal 100 is estimated to have a relatively long time required for conversion of the processing target data of the next terminal 100. Is handled as a low priority SSID.

  In S222, when the CPU 11 determines that the predetermined time has elapsed (S222: Yes), the CPU 11 shifts the process to S225. Therefore, when a certain amount of time has elapsed since the start of timing for the previous terminal 100 that satisfies the predetermined condition, it is highly likely that the conversion for the previous terminal 100 is close to completion. Therefore, in this embodiment, in such a case, the SSID generated for the next terminal is handled as the low priority SSID regardless of whether or not the processing target data of the next terminal 100 is converted.

  In S227, the CPU 11 embeds the SSID and password generated in S221 in the NDEF data. The CPU 11 transmits NDEF data including the SSID and password to the next terminal 100 by NFC communication (S228), and ends this process. When the terminal 100 that is the communication partner of NFC communication receives the NDEF data transmitted in S228, the terminal 100 sets the SSID included in the NDEF data. Then, the terminal 100 transmits the password included in the received NDEF data to the MFP 10 on the condition that the processing target data using the conversion server 200 is completed, as in the case where the NDEF data transmitted in S213 is received. To do. Therefore, if the SSID generated in S <b> 221 is set in the MFP 10, the next terminal 100 and the MFP 10 are connected by Wi-Fi communication with the reception of the password transmitted from the next terminal 100.

  Although details will be described later, if the SSID generated for the next terminal 100 is a high priority SSID, the CPU 11 replaces the low priority SSID generated for the previous terminal 100 with the next terminal 100. Since the corresponding high priority SSID is set, the next terminal 100 is prioritized over the previous terminal 100 and connected to the MFP 10 by Wi-Fi communication. On the other hand, when the SSID generated for the next terminal 100 is the low priority SSID, the CPU 11 sets the low priority SSID after the start of the printing process performed for the previous terminal 100. Therefore, in such a case, the next terminal 100 is connected to the MFP 10 by Wi-Fi communication after the start of the printing process performed on the previous terminal 100.

  On the other hand, when the CPU 11 determines in S220 that the next terminal 100 and the previous terminal 100 are the same terminal (S220: Yes), the CPU 11 sets the terminal flag to ON (S230) and performs this process. finish. The “same terminal flag” is a flag indicating whether or not the next terminal 100 is the same terminal as the previous terminal 100, and is provided in the RAM 13. When the terminal flag is set to ON, it indicates that the next terminal 100 and the previous terminal 100 are the same terminal. The terminal flag is set to off with the start of this process. According to S220 and S230, when the next terminal 100 is the same terminal as the previous terminal 100, the SSID corresponding to the next terminal 100 is not generated. Although details will be described later, NFC printing by the next terminal 100 uses Wi-Fi communication using the SSID generated for the previous terminal 100.

  FIG. 3 is a flowchart showing Wi-Fi connection processing executed by the CPU 11 of the MFP 10 according to the control program 12a. This process is a process for establishing Wi-Fi communication during NFC printing. This process is started by the CPU 11 when the MFP 10 is turned on.

  The CPU 11 uses the high priority SSID set in S214 to determine whether the terminal 100 and Wi-Fi communication are connected, that is, whether Wi-Fi communication is established between the terminal 100 and the MFP 10. (S301). Specifically, when the CPU 11 receives the password corresponding to the SSID set in S214 from the terminal 100, that is, the password included in the NDEF data transmitted in S212, the CPU 11 uses the SSID being set. It is determined that the connection is established by Wi-Fi communication. At this time, if the SSID being set is a high priority SSID, the CPU 11 affirms the determination in S301.

  When the CPU 11 affirms the determination in S301 (S301: Yes), the CPU 11 waits to receive a print instruction from the connection destination terminal 100 by Wi-Fi communication (302: No). When a print instruction is received from the terminal 100 (S302: Yes), the CPU 11 waits to receive image data for printing from the connected terminal 100 via Wi-Fi communication (S303: No).

  On the other hand, when the CPU 11 denies the determination in S301 (S301: No), the CPU 11 determines whether the terminal 100 is connected to the terminal 100 by Wi-Fi communication using the low priority SSID set in S214. (S312). In S312, the CPU 11 performs the same determination as in S301 described above except that the target SSID is a low priority SSID. When the CPU 11 affirms the determination in S312 (S312: Yes), the CPU 11 determines whether a print instruction is received from the connection destination terminal 100 by Wi-Fi communication (S313). If the CPU 11 determines that a print instruction has been received from the terminal 100 (S313: Yes), the CPU 11 sets the next standby flag to off (S314), and the process proceeds to S303.

  In S303, when image data for printing is received from the terminal 100 (S303: Yes), the CPU 11 starts print processing for causing the printer unit 19 to print an image based on the received image data (S304). After the process of S304, the CPU 11 determines whether the waiting SSID is stored in the RAM 13 (S305). The waiting SSID starts NFC communication with the next terminal 100 during a period of waiting for the start of NFC communication with the next terminal 100 after NFC communication is started with the previous terminal 100. In this case, among the SSIDs generated for both terminals 100, the SSID is set to the rear side, that is, the second SSID.

  When the CPU 11 determines that the standby SSID is stored in the RAM 13 (S305: Yes), the CPU 11 sets the standby SSID (S306). The CPU 11 performs polling for the SSID set in S306 (S307). As a result of the processing of S307, the terminal 100 corresponding to the standby SSID transmits a password to the MFP 10 upon reception of polling, thereby establishing Wi-Fi communication using the standby SSID.

  After the process of S307, the CPU 11 waits to be connected to the terminal 100 by Wi-Fi communication using the standby SSID (S308: No). When the terminal 100 and the MFP 10 are connected by Wi-Fi communication (S308: Yes), the CPU 11 moves the process to S302. According to the above S305 to S308, when the SSID is generated for each of the previous terminal 100 and the next terminal 100, the MFP 10 continues to the previously performed printing process, and the MFP 10 corresponds to the standby SSID. Can establish Wi-Fi communication.

  On the other hand, when the CPU 11 determines that the waiting SSID is not stored in the RAM 13 in S305 (S305: No), the CPU 11 determines whether or not the terminal flag is set to ON (S309). That is, the CPU 11 determines whether the next terminal 100 is the same terminal as the previous terminal 100. When the CPU 11 determines that the terminal flag is set to ON (S309: Yes), the CPU 11 sets the terminal flag to OFF (S310) and connects using the connected Wi-Fi communication. A print instruction request is transmitted to the previous terminal 100 (S311).

  As a result of the processing in S <b> 311, the terminal 100 that has received the print instruction request, that is, the same terminal as the previous terminal 100 transmits the print instruction to the MFP 10. Therefore, after the process of S311, the CPU 11 shifts the process to S302 and waits for reception of a print instruction. According to the above S309 to S311, when the previous terminal 100 and the next terminal 100 are the same terminal, the next printing is performed without switching the connection by Wi-Fi communication following the previous printing process. Processing can be performed. On the other hand, when the CPU 11 determines that the terminal flag is not set to ON (S309: No), it indicates that the next terminal 100 does not exist. Therefore, in such a case, the CPU 11 moves the process to S301.

  The CPU 11 is not connected to the terminal 100 by Wi-Fi communication using the low priority SSID set in S214, or receives the print instruction from the connection destination terminal 100 although it is connected. If it is determined that it has not been performed (S312: No or S313: No), the CPU 11 determines whether the next terminal flag is set to ON (S315). When the CPU 11 determines that the next terminal flag is not set to ON (S315: No), the CPU 11 proceeds to S301.

  On the other hand, when the CPU 11 determines that the next terminal flag is set to ON (S315: No), it indicates that the NFC communication with the next terminal 100 is started after the NFC communication is started with the previous terminal 100. This indicates that NFC communication with the next terminal 100 has been started during the period of waiting for the start of. Therefore, in such a case, the CPU 11 executes the processes of S316 to S325. Specifically, the CPU 11 sets the next terminal flag to OFF (S316), and sets the next standby flag to OFF (S317).

  The CPU 11 determines whether the terminal flag is set to ON (S318). When the CPU 11 determines that the terminal flag is not set to ON (S318: No), if the SSID generated for the next terminal 100 is a high priority SSID (S319: Yes), the CPU 11 It is determined whether or not the terminal 100 is currently connected by Wi-Fi communication (S320). When the CPU 11 determines that the connection is being made (S320: Yes), the CPU 11 disconnects the connected Wi-Fi communication (S321), and sets the high priority SSID corresponding to the next terminal 100 (S322).

  On the other hand, if the CPU 11 determines that it is not connected to the previous terminal 100 by Wi-Fi communication, the CPU 11 skips the process of S321 and shifts the process to S322. After the process of S322, the CPU 11 waits for connection with the next terminal 100 by Wi-Fi communication (S323: No). When the password is received from the next terminal 100 and the MFP 10 and the next terminal 100 are connected by Wi-Fi communication (S323: Yes), the CPU 11 shifts the processing to S302. According to the processing of S318 to S323, when the SSID generated for the next terminal 100 different from the previous terminal 100 is the high priority SSID, the next terminal 100 is connected to the Wi before the previous terminal 100. -Connected by Fi communication. Thereby, the printing process of the next terminal 100 is performed before the previous terminal 100.

  In S319, if the SSID generated for the next terminal 100 is not a high priority SSID, that is, if it is a low priority SSID (S319: No), it must be connected to the previous terminal 100 by Wi-Fi communication. If this is the case (S324: No), an SSID (ie, low priority SSID) corresponding to the previous terminal is set (S325), and the process proceeds to S323.

  On the other hand, if the previous terminal 100 is already connected by Wi-Fi communication in S324 (S324: Yes), the CPU 11 shifts the process to S302. According to the processes of S319, S324, and S325, when the SSIDs generated for the previous terminal 100 and the next terminal 100 are both low priority SSIDs, the NFC communication is started in the order in which they are started. . That is, the printing process of the previous terminal 100 is performed before the printing process of the next terminal 100. In S318, when the CPU 11 determines that the terminal flag is set to ON (S318: Yes), the CPU 11 shifts the process to S324.

  According to the MFP 10 of this embodiment, when the destination terminal 100 that has started NFC communication is converting the processing target data using the conversion server 200, the SSID generated for the next terminal 100 is used. Is stored in the RAM 13, the printing process for the next terminal 100 can be executed without starting the NFC printing again with the next terminal 100 after the printing process for the previous terminal 100 is started. In particular, when the SSID generated for the next terminal 100 is handled as a high priority SSID, the print process for the next terminal 100 can be performed prior to the print process for the previous terminal 100. When the terminal 100 uses the printing function (printing process) of the MFP 10 using NFC communication, it is possible to cause each terminal 100 to use the printing process in a suitable order.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the above-described embodiment, the MFP 10 is exemplified as the function execution device of the present invention. However, the MFP 10 is not limited to the MFP 10 having a plurality of functions as long as the device can execute at least one function. A device specialized in the above can also be adopted as the function execution device of the present invention.

  In the above embodiment, the print function is exemplified as an example of the function of the MFP 10 used by the terminal 100 capable of NFC communication. However, in the case where a device capable of NFC such as the terminal 100 uses a function other than the print function. The present invention may be applied. For example, the present invention may be applied to a case where the facsimile function of the MFP 10 is transmitted after image data or document data stored in the terminal 100 is converted as necessary.

  In the said embodiment, although terminals, such as a smart phone, were illustrated as the terminal 100, it is not limited to this, A various apparatus is employable as an external apparatus if it is an apparatus comprised so that NFC communication is possible. For example, when devices such as tablet terminals, personal computers, digital cameras, and music playback devices are configured to be able to perform NFC communication, these devices can be used as external devices that use functions that the MFP 10 can execute. Good.

  In the above embodiment, the OS 112a of the terminal 100 has been described as an Android OS. However, another OS may be employed. In the above-described embodiment, NFC communication is exemplified as short-range wireless communication. However, non-contact communication conforming to other standards such as TransferJet (registered trademark) may be employed. In the above embodiment, the terminal 100 is configured to upload and convert the processing target data to the conversion server 200 that is an external device. However, the conversion may be performed by a conversion unit included in the terminal 100.

  In the above embodiment, as the SSID for performing Wi-Fi communication between the MFP 10 and the terminal 100, the SSID that permits the establishment of Wi-Fi communication on the condition of one-time use is exemplified. The above-described embodiment can be applied even to an SSID whose limit is a predetermined number other than one or an SSID whose number of uses is not limited.

  In the above-described embodiment, the SSID generated for the next terminal 100 according to whether or not the next terminal 100 is performing conversion using the conversion server 200 and the number of pages of processing target data to be converted. Is assigned to either the high priority SSID or the low priority SSID, but may be configured to handle all as the low priority SSID regardless of whether or not the next terminal 100 is converting. Also in this modification, since the SSID generated for the next terminal 100 is stored in the RAM 13, when the printing process for the previous terminal 100 is started, NFC communication with the next terminal 100 is started again. The printing process for the next terminal 100 can be executed without doing so.

  In the above embodiment, the CPU 11 is configured to handle the generated SSID as a low priority SSID when the conversion flag is set on and the number of conversion pages is equal to or greater than the predetermined threshold P. The CPU 11 may be configured to handle the generated SSID as a low priority SSID without considering the number of converted pages if the conversion flag is on. Alternatively, if the number of converted pages is 1 or more, the CPU 11 may determine that conversion is being performed and handle the generated SSID as a low priority SSID. In such a case, it is not necessary to include the in-conversion flag in the NDEF data.

  Alternatively, the terminal 100 transmits NDEF data in which the file format of the processing target data is embedded to the MFP 10, and the MFP 10 converts the file format included in the NDEF data received from the terminal 100 to image data such as a PDF file. In the case of a predetermined file format that requires conversion, it may be determined that conversion is being performed using the conversion server 200 and the generated SSID is handled as a low priority SSID.

  In the above embodiment, the “number of conversion pages” is the number of pages of the processing target data that is the original data of the conversion performed by the conversion server 200, but conversion from the processing target data received by the terminal 100 from the conversion server 200 is performed. The number of pages of image data obtained by the above may be the “number of converted pages”. Further, the data size of the processing target data may be used instead of the “number of converted pages”. Further, when the terminal 100 can acquire the remaining conversion amount from the conversion server 200, the conversion remaining amount may be acquired from the terminal 100. According to these modified examples, the case where the data size is equal to or larger than the predetermined size, or the case where the remaining conversion amount is equal to or larger than the predetermined amount corresponds to the case where the number of converted pages is equal to or larger than the predetermined threshold P.

  In the above-described embodiment, the time measurement is started when the CPU 11 determines Yes in S207, but the timing for starting the time measurement is not particularly limited. For example, the timing may be started at the timing when the previous terminal 100 starts NFC communication.

  In the above embodiment, the MFP 10 and the terminal 100 have been described as being connected in the ad hoc mode. However, instead of the ad hoc mode, the two may directly communicate with each other based on the Wi-Fi Direct standard.

  In the above embodiment, the MFP 10 has been described as being configured to be connected to one terminal 100 in the ad hoc mode. However, when the MFP 10 can be connected to the plurality of terminals 100 in the ad hoc mode, that is, the plurality of terminals 100. The above embodiment can also be applied to a configuration capable of storing a plurality of SSIDs for communicating in an ad hoc mode. That is, when it is possible to connect to a plurality of terminals 100 in the ad hoc mode at the same time, even when NFC communication with another terminal 100 is started in a situation where the terminals 100 are connected to the number of SSIDs, The above embodiment can be applied. In such a case, the process of turning on the next standby flag (S209) is skipped until the SSID reaches a storable number, and the process of turning off the next standby flag when the storable number is reached (S209) is executed. It is good to do so.

  In the above-described embodiment, the CPU 11 has been described as a configuration for executing each process described in FIG. 2 and FIG. 3. However, a configuration in which a plurality of CPUs cooperatively execute each process described in each of these drawings. Also good. Further, an IC such as an ASIC may be configured to execute each process described in each of the above drawings independently or in cooperation with a plurality of ICs. Further, the CPU 11 and an IC such as an ASIC may cooperate to execute each process described in the above drawings.

From the start of communication with the first device via the first communication unit to the time when an execution instruction for causing the function unit to execute a function process is received from the first device, When communication via a second communication device that is a different external device and the first communication unit is started, a second information that is wireless information different from the first information is generated based on the start of the communication. Generating means;
Transmitting means for transmitting the wireless information generated by the first generating means or the second generating means to a corresponding external device;
Storage control means for storing the second information generated by the second generation means in the storage unit;
Setting means for setting the wireless information generated by the first generation means or the second generation means to perform communication via the second communication unit;
Based on the setting of the wireless information by the setting unit, the external device to which the set wireless information is transmitted by the transmitting unit is set as a partner device, and the first wireless device using the set wireless information is used. Instruction receiving means for receiving the execution instruction from the counterpart device by communication via two communication units;
When the instruction receiving unit receives the execution instruction from the counterpart device, the processing target data received from the counterpart device or the data of the predetermined file format is used by communication via the second communication unit. As function execution means for causing the function unit to execute the function processing,
Make the control function,
When the second information is generated by the second generation unit, the setting unit determines that the first device is executing conversion using the conversion unit by the first determination unit. The execution of the functional processing includes the processing target data or the data of the predetermined file format by communication via the second communication unit using the first information set prior to the second information. The function execution program sets the second information stored in the storage unit by the storage control means in place of the set first information on condition that the reception of the information related to is completed.
