  In step S101, the CPU 201 of the base terminal 001 acquires a master from an external storage device such as a connected USB memory.

  The master in this embodiment is information on a product ID and its unit price, information on a credit card number and type, information on currency, information on a product loaded in a cart for in-flight sales, etc. Contains information needed to sell the product.

  In step S102, the CPU 201 of the parent terminal 001 compares the master acquired from the external storage device such as a USB memory with the master stored in the main body, and synchronizes the main body and the external storage device with the latest master.

  In step S103, the CPU 201 of the parent device terminal 001 first transmits a communication start signal for notifying the child device terminal that communication is to be started. The communication start signal includes information to start communication from now on and an instruction to collect various data held by each slave terminal in the master terminal.

  Then, in order to share the master synchronized in step S102 with each of the child device terminals 002 to 004, a master sharing instruction is transmitted to the child device terminals. The master sharing instruction includes the latest master data and information for identifying the master terminal.

  In step S104, the CPU 201 of the parent device terminal 001 determines whether or not the master device can be shared with all the child device terminals.

  Specifically, determination is made based on whether or not a slave unit end signal is received from the slave unit terminal. Moreover, you may judge by whether the identification information (HTID) of all the subunit | mobile_unit terminals was acquired.

  With the above processing, the latest master data can be shared with all the connected mobile terminals.

  In step S201, the CPU 201 of the slave terminal receives the communication start signal transmitted from the master terminal 001. Further, the received communication start signal is sequentially transferred to the adjacent handset terminal.

  In step S202, the CPU 201 of the slave terminal prepares for communication based on the communication start signal received in step S201. Here, the slave terminal located at the end detects that it is the terminal at the end. Specifically, if there is a mobile terminal only on either side, it is determined that the terminal is an end terminal. On the other hand, if there are portable terminals on both sides, it is determined that the terminal is not an end terminal. Or, it may be set in advance for the terminal at the end.

  In step S203, the CPU 201 of the slave terminal determines whether a master sharing instruction has been received from the master terminal or another slave terminal. This master sharing instruction includes IDs of other child device terminals and the like.

  If a master sharing instruction has been received (step S203: YES), the process proceeds to step S204.

  If the master sharing instruction has not been received (step S203: NO), the process waits until the master sharing instruction is received.

  In step S204, the CPU 201 of the child device terminal receives master data transmitted from the parent device terminal or another child device terminal. Then, the master data is stored in the own device.

  In step S205, the CPU 201 of the slave terminal adds its own ID and prepares for transmission.

  In step S206, the CPU 201 of the slave terminal determines whether or not the own terminal is a terminal located at the end. This determination is made based on the determination in step S202 described above.

  If it is determined that the terminal is located at the end (step S206: YES), the process proceeds to step S208.

  If it is determined that the terminal is not located at the end (step S206: NO), the process proceeds to step S207.

  In step S207, the CPU 201 of the slave terminal transfers the master sharing instruction received in step S203 to the adjacent slave terminal. At this time, not only the master sharing instruction but also the master data and the own device ID are transferred together. Then, the process shown in this flowchart is terminated.

  In step S503, the child device terminal 003 receives the master data, master sharing instruction, and HTID (for the parent device terminal 001 and the child device terminal 002) transmitted from the child device terminal 002, and assigns the ID of the own device to them. Add and send to 004.

  In step S504, slave unit terminal 004 receives master data, master sharing instruction, and HTID (for base unit terminal 001 and slave unit terminals 002 and 003) transmitted from slave unit terminal 003. Since it is determined that the own device is the terminal located at the end, the ID of the own device and the slave device end signal (a signal indicating that the master data can be shared by all the slave devices) are sent to the master device terminal 001. To send.

  Here, base unit terminal 001 is moved by the user from the right end (right side of handset 001) to the left end (left side of handset 004).

  Then, base unit terminal 001 receives the slave unit end signal from slave unit terminal 004, and determines that the master data is shared by all the slave units.

  In this way, since the information is finally transmitted to the parent device terminal by moving the position of the terminal (master device terminal) that first transmitted the data, the data is simply transmitted from the parent device terminal. More reliable than That is, it is possible to confirm that data cannot be shared with all terminals due to an error in communication on the way.

  Further, it is possible to reduce the amount of data communication and shorten the processing time as compared with the case where data is reciprocated again from the end of the connected slave terminal.

  Next, a data collection process performed by the parent terminal 001 in the embodiment of the present invention will be described with reference to FIG.

  Note that the processing shown in the flowchart of FIG. 5 is processing in which the CPU 201 of the parent terminal 001 reads and executes a predetermined control program.

  In step S301, CPU 201 of base unit terminal 001 receives a sales data collection instruction.

  In step S302, CPU 201 of base unit terminal 001 determines whether or not sales data has been received. The sales data received here is the sales data of each slave terminal. FIG. 9 shows an example of sales data.

  If sales data is received (step S302: YES), the process proceeds to step S303.

  When sales data is not received (step S302: NO), it waits until sales data is received.

  In step S303, CPU 201 of base unit terminal 001 counts the sales data received in step S302. An example of the aggregated sales data is shown in FIG.

  By such processing, sales data stored in each slave terminal can be collected in the master terminal.

  Next, a data collection process performed by the slave terminal in the embodiment of the present invention will be described with reference to FIG.

  Note that the processing shown in the flowchart of FIG. 6 is processing in which the CPU 201 of the slave terminal reads and executes a predetermined control program.

  In step S401, the CPU 201 of the child device terminal determines whether or not the own device is a terminal located at the end.

  If the terminal is located at the end (step S401: YES), the process proceeds to step S406.

  If the terminal is not located at the end (step S401: NO), the process proceeds to step S402.

  In step S402, the CPU 201 of the slave terminal receives a sales data collection instruction.

  In step S403, CPU 201 of the slave terminal determines whether or not sales data has been received.

  When sales data is received (step S403: YES), the process proceeds to step S404.

  If sales data has not been received (step S403: NO), the system waits until sales data is received.

  In step S405, the CPU 201 of the slave terminal adds its own ID and the like to the sales data received in step S403, and prepares for transmission to other terminals.

  In step S405, the CPU 201 of the slave terminal adds the sales data of its own device to the sales data received in step S403.

  In step S406, CPU 201 of the slave terminal transmits a sales data collection instruction.

  Here, if it is the terminal at the end (step S401: YES), the sales data and ID of its own device are transmitted to the adjacent portable terminal together with the sales data collection instruction.

  If the terminal is not the terminal (step S401: NO), the sales data and ID of the other mobile terminal received from the other mobile terminal are added to the sales data and the data added with the ID along with the sales data collection instruction. To your mobile device.

  In step S407, CPU 201 of the slave terminal determines whether or not the sales data has been transmitted. Then, when the transmission of the sales data is completed, the processing of this flowchart is terminated.

  Here, the processing shown in the flowcharts of FIGS. 5 and 6 will be described with reference to FIG.

  In step S601, since the child device terminal 004 is a terminal located at the end, the child device terminal 004 transmits the sales data and ID of the own device together with the sales data collection instruction to the child device terminal 003 that is the adjacent terminal.

  Note that the transmission timing is triggered by the timing instructed by the user.

  In step S602, the child device terminal 003 adds its own sales data and ID to the data transmitted from the child device terminal 004 in step S601, and with the sales data collection instruction, the child device terminal 002 that is the adjacent terminal. Send to.

  In step S603, handset terminal 002 adds its own sales data and ID to the data sent from handset terminal 003 in step S602, and sends it to base unit terminal 001.
