The nonvolatile memory 54 is a storage device that stores data even after the communication terminal device 3 is turned off. For example, a flash memory, an EEPROM, an SD card, a magnetic storage device, or the like can be used.

  The ROM 52 stores programs such as an OS (Operating System: basic software) 521 and application programs (POS application 522 and print control application 523). The OS 521 is not particularly limited, and may be a generally known OS such as iOS (registered trademark), Android (registered trademark), Windows (registered trademark) RT, Windows (registered trademark) 8, or the like. The application program will be described with reference to FIG.

  Next, functional blocks of the control unit 50 will be described with reference to FIG. The functional block is realized by the cooperation of hardware and software, such as the CPU 51 provided in the control unit 50 reads and executes the program recorded in the ROM 52. The control unit 50 includes a transaction processing unit 56 that performs transaction processing and a print control unit 57 that performs print control as functional blocks. The accounting processing unit 56 is realized by the CPU 51 reading and executing the POS application 522 stored in the ROM 52, and the communication terminal device 3 functions as an accounting input / output device. Similarly, in the print control unit 57, the communication terminal device 3 functions as a print control device by the CPU 51 executing the print control application 523.

  The accounting processing unit 56 performs accounting processing based on input information from the touch panel 32. That is, the accounting processor 56 generates accounting data based on the input information (purchased product information, etc.) and information obtained from the POS server 7 (for example, information on the product code, product name, and amount, etc.). To do. The accounting processing unit 56 passes the generated accounting processing data to the print control unit 57.

  The print control unit 57 includes a reading control unit 571, a transmission destination setting unit (control unit) 572, and a print data transmission unit 573.

  The reading control unit 571 controls the NFC reading unit 31 to read the MAC address from the NFC tag 21 of the printing apparatus 2. Further, the reading control unit 571 inputs a captured image of the imaging camera 33. The reading control unit 571 reads the MAC address by analyzing and decoding the image of the QR code 27 captured by the imaging camera 33. The reading control unit 571 passes the MAC address to the transmission destination setting unit 572.

  The transmission destination setting unit 572 sets a transmission destination of print data based on the MAC address passed from the reading control unit 571. Specifically, the transmission destination setting unit 572 acquires the IP address (address on the communication network) of the printing apparatus 2 having the MAC address based on the read MAC address, and uses the acquired IP address of the print data. Set the output destination. Details of the processing of the transmission destination setting unit 572 will be described later.

  The print data transmission unit 573 transmits the transaction processing data acquired from the transaction processing unit 56 to the printing apparatus 2 as receipt print data. That is, the print data transmission unit 573 transmits print data to the transmission destination (IP address) set by the transmission destination setting unit 572. The print data is transmitted to the printing apparatus 2 via the access point 4 by wireless LAN.

  An address management table is stored in the nonvolatile memory 54 of the communication terminal device 3. FIG. 6 shows an example of the address management table. In the address management table, the MAC address of the network device 22 included in the printing apparatus 2 connected to the in-store LAN 6 and the IP address of the corresponding printing apparatus 2 are registered in association with each other.

A procedure for creating an address management table by the transmission destination setting unit 572 will be described with reference to the sequence diagram shown in FIG.
The transmission destination setting unit 572 generates a request packet (inquiry packet) that requests transmission of the IP address and the MAC address at a predetermined timing such as when the communication terminal device 3 is activated. Other examples of the predetermined timing include a timing when the print control application 523 is activated and a connection to the network. The transmission destination setting unit 572 sets a broadcast address as the destination address of the generated request packet and broadcasts it to the in-store LAN 6. FIG. 7 shows a case where there are three printing apparatuses connected to the in-store LAN 6: the printing apparatuses 2A, 2B, and 2C. The broadcast request packet is received by each printing device 2 of the printing devices 2A, 2B, and 2C.

Each of the printing apparatuses 2A, 2B, and 2C that has received the request packet returns a response packet of its own MAC address and IP address to the requesting communication terminal apparatus 3 according to the request packet.
For example, the MAC address and the IP address of the printing apparatus 2A are stored as device information in the memory 25 provided in the printing control unit 24 of the printing apparatus 2A. When the print control unit 24 receives a request packet via the network device 22, it reads the device information from the memory 25 and generates a response packet including the read device information as data. The print control unit 24 transmits the generated response packet to the communication terminal device 3 that is the transmission source of the request packet via the network device 22. The other printing apparatuses 2B and 2C perform the same process as the printing apparatus 2A.
The MAC address in the device information may be stored in a memory (not shown) included in the network device 22, or the IP address may be stored in an OS registry included in the print control unit 24.

  When receiving the response packet from the printing apparatus 2, the transmission destination setting unit 572 of the communication terminal device 3 extracts the MAC address and the IP address from the received response packet. The transmission destination setting unit 572 associates the extracted MAC address with the IP address and registers them in the address management table shown in FIG.

  Further, when the MAC address recorded in the NFC tag 21 of the printing apparatus 2 to which the print data is to be printed is read by the NFC reading unit 31, the transmission destination setting unit 572 refers to the address management table and corresponds to the corresponding IP address. To get. The transmission destination setting unit 572 sets the acquired IP address as a destination address for transmitting print data.

Next, the POS server 7 will be described with reference to FIG. FIG. 8 shows an example of the configuration of the POS server 7.
The POS server 7 includes a CPU 71 and a memory such as a ROM 72 and a RAM 73 as hardware, and processes information stored in a buffer 735 in the RAM 73 in accordance with a control program stored in the ROM 72. Further, in the RAM 73, there are provided a product code block 731 in which a product code that is an identification code of each product is recorded, and a product name block 732 in which the product name of each product is recorded. In the RAM 73, an amount block 733 that records the amount of each product and an inventory block 734 that records the stock of the product are provided. The CPU 71 extracts information on the amount of the corresponding product based on the product code transmitted from the communication terminal device 3 and transmits the information to the corresponding communication terminal device 3.

  Although not shown in FIG. 8, the accounting process performed by the accounting processing unit 56 of the communication terminal device 3 may be performed by the POS server 7. That is, the accounting processing unit 56 of the communication terminal device 3 transmits the product code of the product received by the touch panel 32 to the POS server 7 via the wireless communication unit 34. When receiving the product code from the communication terminal device 3, the POS server 7 specifies the product based on the received product code, and calculates the payment amount with reference to the amount block 733. The POS server 7 transmits the product name, the payment amount, etc. of the specified product to the printing apparatus 2 as print data, and causes the printing apparatus 2 to print. Note that the printing apparatus 2 that transmits print data is a printing apparatus that is designated by the communication terminal apparatus 3 by an IP address or a MAC address.

  Next, a processing procedure of the communication terminal device 3 will be described with reference to a flowchart. The processing flow described with reference to FIGS. 9 to 11 is a flow when the user uses the POS system 1 in the first usage mode. In the first usage mode, for example, the user moves in the store carrying both the communication terminal device 3 and the printing device 2. When carrying these devices, the user sets (pairing settings) the print data transmission destination of the communication terminal device 3 to the printing device 2 that is carried together. When printing of a receipt or the like becomes necessary, print data is transmitted from the communication terminal device 3 to the printing device 2 set for pairing, and the printing device 2 is made to perform printing.

First, the procedure for creating the address management table shown in FIG. 6 will be described with reference to the flowchart shown in FIG. The address management table creation process is realized by control by the transmission destination setting unit 572 of the control unit 50.
The destination setting unit 572 executes the address management table creation process at a predetermined timing such as when the communication terminal apparatus 3 is activated, when the print control application 523 is activated, or when connected to the network.

  The transmission destination setting unit 572 first generates a request packet (step S1). The transmission destination setting unit 572 generates a request packet that requests transmission of the IP address and the MAC address. When the transmission destination setting unit 572 generates a request packet, the transmission destination setting unit 572 sets a broadcast address as the destination address of the generated request packet, and broadcasts it to a terminal connected to the in-store LAN 6 (step S2).

  When the request packet is broadcast, the transmission destination setting unit 572 determines whether a response packet to the request packet has been received (step S3). When receiving the response packet from the communication terminal device 3 or the printing device 2 connected to the in-store LAN 6, the transmission destination setting unit 572 extracts the MAC address and IP address included in the received response packet, and stores them in the address management table. Register (step S4).

  Next, the transmission destination setting unit 572 determines whether or not a predetermined time has elapsed since the transmission of the request packet performed in step S2 (step S5). That is, the transmission destination setting unit 572 determines whether or not a timeout time has elapsed. In the case of a positive determination (step S5 / YES), the transmission destination setting unit 572 ends this process. If the determination is negative (step S5 / NO), the transmission destination setting unit 572 returns to step S3 and waits for reception of a response packet (step S3).

  Next, a transmission destination setting process for setting the printing apparatus 2 selected by the user as a transmission destination of print data will be described with reference to the flowchart shown in FIG. This transmission destination setting process is performed under the control of the reading control unit 571 and the transmission destination setting unit 572 of the control unit 50. In the first usage mode, when the user carries the communication terminal device 3 and the printing device 2, the user causes the communication terminal device 3 to execute the transmission destination setting process.

  A user who possesses the communication terminal device 3 first brings the communication terminal device 3 close to the NFC tag 21 of the printing device 2 to which print data is to be printed. That is, the communication terminal device 3 is held over the NFC tag 21 of the printing device 2. When the distance between the NFC reading unit 31 of the communication terminal device 3 and the NFC tag 21 approaches the distance at which short-range wireless communication is possible, the reading control unit 571 controls the NFC reading unit 31 and records it in the NFC tag 21. The read MAC address is read (step S11).

  When the MAC address read by the NFC reading unit 31 is input, the transmission destination setting unit 572 refers to the address management table and determines whether or not the input MAC address is registered in the address management table (step S12). ). In the case of negative determination (step S12 / NO), the transmission destination setting unit 572 displays an error message on the touch panel 32 indicating that the MAC address read by the NFC reading unit 31 is not registered. In this case, the transmission destination setting unit 572 updates the address management table after performing the address management table creation process described in FIG. 9 again. Therefore, the transmission destination setting unit 572 causes the touch panel 32 to display a message “Please wait until the address management table is updated” (step S13). If the determination is affirmative (YES in step S12), the transmission destination setting unit 572 acquires an IP address associated with the read MAC address from the address management table (step S14). Then, the control unit 50 sets the acquired IP address as a destination address indicating a transmission destination of the print data (step S15). As a result, the IP address corresponding to the MAC address read by the NFC reading unit 31 is set as the transmission destination of the print data.

Next, a printing process for issuing a receipt will be described with reference to the flowchart shown in FIG. The printing process in the communication terminal device 3 is realized by control by the accounting processing unit 56 and the print data transmission unit 573. The print processing is performed in a state where the address management table creation processing described with reference to FIG. 9 and the transmission destination setting processing illustrated in FIG. 10 are performed and the transmission destination of the print data is set.
The accounting processing unit 56 causes the touch panel 32 to display information such as the product name and product code acquired from the POS server 7 in accordance with the input received by the touch panel 32. When a product is selected by the touch panel 32, the product code of the selected product is transmitted to the POS server 7, and the amount information of the selected product is acquired from the POS server 7. The accounting processing unit 56 generates accounting processing data including, for example, the product name, price, and purchase time of the product purchased by the user (step S21), and passes it to the print data transmission unit 573.

  When the accounting data is transferred from the transmission destination setting unit 572, the print data transmission unit 573 controls the wireless communication unit 34 to transmit the accounting processing data as print data to the printing apparatus 2 (step S22). At this time, the print data transmission unit 573 transmits the print data to the destination address (IP address) set by the transmission destination setting process (step S22). The print data is transmitted to the printing apparatus 2 via the access point 4 by wireless LAN.

  The printing apparatus 2 that is the transmission destination of the print data receives the print data of the receipt transmitted from the communication terminal apparatus 3 (step S31), and prints (issues) the receipt based on the received print data (step S32). .

  Further, the communication terminal apparatus 3 transmits a status request for requesting the print status to the printing apparatus 2 that has transmitted the print data (step S23). When receiving the status request (step S33), the printing apparatus 2 generates status information indicating the status of the printing process, and transmits the status information to the communication terminal apparatus 3 that transmitted the request (step S34). The status information includes, for example, “normal end” when printing ends normally, “out of receipt paper” and “out of ink” indicating the cause when printing is not ended.

  When receiving the status information from the printing apparatus 2 (step S24), the print data transmission unit 573 of the communication terminal apparatus 3 displays the received status information on the touch panel 32. When the user of the communication terminal device 3 refers to the display on the touch panel 32, when printing cannot be performed, the cause can be specified.

  In the processing flows shown in FIGS. 9 to 11, the processing flow in the first usage pattern has been described. However, in the second usage pattern, processing is performed in the same processing flow. However, the execution timing of the transmission destination setting process described with reference to FIG. 10 differs between the first usage mode and the second usage mode. That is, in the first usage mode, when the user carries the communication terminal device 3 and the printing device 2 in the transmission destination setting process, the printing device that carries the transmission destination of the print data of the communication terminal device 3 together. 2 (pairing setting). On the other hand, in the second usage mode, when the user carries the communication terminal device 3 and needs to print a receipt, the user sets the nearest printing device 2 as the transmission destination of the print data. In the second usage mode, printing may be set to start when the NFC reading unit 31 reads the MAC address recorded in the NFC tag 21 as a trigger. In other words, the transmission destination setting unit 572 acquires the IP address that is the transmission destination of the print data with reference to the address management table in response to the input of the MAC address from the NFC reading unit 31, and the IP address to be acquired is acquired. Set to the destination address of the print data. Further, the accounting processing unit 56 passes the print data to the print data transmission unit 573 when the MAC address is input from the NFC reading unit 31. When the print data transmission unit 573 acquires the print data from the accounting processing unit 56, the print data transmission unit 573 transmits the acquired print data to the destination address (IP address). That is, the print data is transmitted to the printing apparatus 2 via the access point 4 by the wireless LAN.

  As described above, the communication terminal device 3 according to the embodiment to which the present invention is applied includes the wireless communication unit 34, the NFC reading unit 31, and the transmission destination setting unit 572. The wireless communication unit 34 can access the printing apparatus 2 to be controlled connected to the in-store LAN 6 via the access point 4 and the in-store LAN 6. The NFC reading unit 31 reads a MAC address that identifies the printing apparatus 2. The transmission destination setting unit 572 accesses the printing apparatus 2 through the wireless communication unit 34 and acquires an IP address corresponding to the MAC address. Therefore, the communication terminal apparatus 3 can easily acquire information necessary for connection with the printing apparatus 2 and start communication with the printing apparatus 2.

  Further, the transmission destination setting unit 572 may access the printing apparatus 2 by transmitting an inquiry packet to the in-store LAN 6 using broadcast, and obtain an IP address from the printing apparatus 2 specified by the MAC address. it can. Therefore, the communication terminal device 3 can easily acquire information necessary for connection with the printing device 2.

  Further, the transmission destination setting unit 572 displays on the touch panel 32 that the acquisition of the IP address has failed when the IP address cannot be acquired. Accordingly, it is possible to notify the user that the acquisition of the IP address has failed and to prompt the user to take subsequent actions.

  Further, the NFC reading unit 31 reads the MAC address recorded on the NFC tag attached to the printing apparatus 2. The QR code MAC address affixed to the printing apparatus 2 is imaged by the imaging camera 33, and the MAC address is read from the captured image. Therefore, it is possible to acquire a MAC address that identifies the printing apparatus 2 with a generally known simple configuration.

  Further, a MAC address is used as identification information for identifying the printing apparatus 2 and an IP address is used as an address on the communication network.
