  Next, a procedure for changing the display of the shelf label 104 using the handy terminal 105 in the present embodiment will be described with reference to FIGS. 7 and 8 as appropriate. First, the processing of the handy terminal 105 will be described with reference to FIG. First, the store clerk uses the handy terminal 105 to obtain the identification ID of the shelf label 104. In the operation inside the handy terminal 105, the reading unit 609 reads the barcode of the shelf label 104 to be changed in display, and acquires the identification ID (step S701). Subsequently, the clerk inputs price information indicating the changed price into the input unit 607. The input unit 607 receives input of price information (step S702). Subsequently, the control unit 603 transmits a change request including the price information, the identification ID, and the terminal identification number of the handy terminal 105 to the communication controller 102 via the communication unit A605. Subsequently, the control unit 603 receives a response message to the change request from the communication controller 102 via the communication unit A 605 (step S704). Subsequently, the control unit 603 determines whether or not the change is possible based on the response message received from the communication controller 102 (step S705). If the change is possible, the communication unit B 606 transmits price information to the shelf label 104 (step S706), and ends the process. If the change is impossible, the process is terminated. If the handy terminal 105 is equipped with the printing unit 610 after step S706, it is also possible to perform processing for printing discount information or the like on a sticker.

  Next, processing in the communication controller 102 will be described with reference to FIG. First, the communication unit 207 of the communication controller 102 receives the change request transmitted from the communication unit A 605 of the handy terminal 105. Subsequently, the control unit 203 of the communication controller 102 determines whether or not the handy terminal 105 that has transmitted the change request has a change authority (step S802). For this determination, a list stored in the storage unit 204 is used. This list associates the terminal identification number of the handy terminal with the shelf label ID of the shelf label 104 whose display price may be changed. For example, the list is created and stored by the communication controller 102 or the server 101. To do. When the set of terminal identification number and shelf label ID included in the change request transmitted from the handy terminal 105 matches the set of terminal identification number and shelf label ID in the list stored in the storage unit 204, It is determined that the handy terminal 105 has change authority. Further, the set of terminal identification number and shelf label ID included in the change request transmitted from the handy terminal 105 did not match the set of terminal identification number and shelf label ID in the list stored in the storage unit 204. In this case, it is determined that the handy terminal 105 has no change authority.

  When there is a change authority, the control unit 203 of the communication controller 102 updates the price of the product master stored in the storage unit 204 to the price indicated by the price information included in the change request transmitted from the handy terminal 105. At the same time, a change request including the changed price information and shelf label ID is transmitted to the server 101 in order to similarly change the contents of the product master stored in the storage unit (step S803). Subsequently, the control unit 203 of the communication controller 102 transmits a changeable message to the control unit 603 of the handy terminal 105 (step S804), and ends the process. If it is determined in step S802 that there is no change authority, the control unit 203 of the communication controller 102 transmits a non-changeable message to the control unit 603 of the handy terminal 105 (step S805), and the process ends.

  Next, processing of the shelf label 104 will be described. The receiving unit 502 of the shelf label 104 receives the changed price information from the communication unit B 606 of the handy terminal 105. The control unit 504 of the shelf label 104 changes the price information displayed on the display unit 503 based on the changed price information received by the receiving unit 502.

  By the above procedure, the display of the electronic shelf label can be changed at the place where the electronic shelf label is installed. In addition, the store clerk can change the display price of the electronic shelf label device as needed. In addition, since the display of the electronic shelf label can be changed without going back and forth between the merchandise store and the backyard, the burden on the store clerk is reduced. Further, since the display of the electronic shelf label can be changed as needed, the customer does not misunderstand the display information.

  Next, the function of limiting the price reduction and price increase will be described with reference to FIGS. 9 and 10 as appropriate. FIG. 10 is a diagram of a product master when the product price reduction and price increase limiting functions are used. The upper limit 1006 is an upper limit of a settable price. The lower limit 1007 is a lower limit of the settable price. Since the processing at the handy terminal 105 and the shelf label 104 is the same as the procedure for changing the display of the shelf label 104 using the handy terminal 105, the processing at the communication controller 102 will be described.

  First, the communication unit 207 of the communication controller 102 receives the change request transmitted from the communication unit A 605 of the handy terminal 105 (step S901). Subsequently, the control unit 203 of the communication controller 102 determines whether or not the handy terminal 105 that has transmitted the change request has change authority (step S902). The determination method is the same as that in step S802 in FIG. Subsequently, when there is a change authority, the control unit 203 of the communication controller 102 determines whether or not the changed price is a price within the upper limit price 1006 and the lower limit price 1007 in the product master (step S903). When the price is within the upper limit price and the lower limit price, the control unit 203 of the communication controller 102 indicates the price of the product master stored in the storage unit 204 by the price information included in the change request transmitted from the handy terminal 105. Update to At the same time, in order to change the contents of the product master stored in the storage unit based on the change information, the server 101 transmits a change request including the changed price information and the shelf label ID. (Step S904). Subsequently, the control unit 203 of the communication controller 102 transmits a changeable message to the control unit 603 of the handy terminal 105 (step S905), and ends the process. If it is determined in step S902 that there is no change authority, the control unit 203 of the communication controller 102 transmits an unchangeable message to the control unit 603 of the handy terminal 105 (step S906), and the process ends. If it is determined in step S903 that the price after the change is not within the upper limit price and the lower limit price in the product master, the control unit 203 of the communication controller 102 cannot change the control unit 603 of the handy terminal 105. A message is transmitted (step S906), and the process ends.

  The above procedure makes it possible to change the display of the electronic shelf label without setting an unintended price.

  Next, the price reduction calculation function for calculating the price reduction of a product will be described with reference to FIGS. 11 and 12 as appropriate. First, the processing of the handy terminal 105 will be described with reference to FIG. First, the reading unit 609 of the handy terminal 105 reads the barcode of the shelf label 104 to be changed in display, and acquires the identification ID (step S1101). Subsequently, the input unit 607 receives an input of the inventory quantity (step S1102). Subsequently, the control unit 603 sends a price reduction calculation request including the inventory quantity received by the input unit 607, the identification ID read in step S1101 and the terminal identification number of the handy terminal 105 via the communication unit A605. Send to. Subsequently, the control unit 603 receives a response message to the price reduction calculation request from the communication controller 102 via the communication unit A 605 (step S1104). Subsequently, the control unit 603 determines whether or not the change is possible based on the response message received from the communication controller 102 (step S1105). If the response message can be changed, the communication unit B 606 transmits price information to the shelf label 104 (step S1106) and ends the process. If the response message cannot be changed, the process ends.

  Next, processing in the communication controller 102 will be described with reference to FIG. First, the communication unit 207 of the communication controller 102 receives the price reduction change request transmitted from the communication unit A 605 of the handy terminal 105 (step S1201). Subsequently, the control unit 203 of the communication controller 102 determines whether or not the handy terminal 105 that has transmitted the change request has a change authority (step S1202). The determination method is the same as that in step S802 in FIG. If there is a change authority, the control unit 203 of the communication controller 102 calculates the price after the price reduction based on a calculation formula that determines the price of the product after the price reduction depending on the number of stocks and the time until closing (step S1203). At this time, for example, a table in which the number of stocks, the time until closing, and the product price after the price reduction are stored in advance is stored, and the table after the price reduction corresponding to the number of stocks and the time until closing is used. The product price may be read from the table.

  Subsequently, the control unit 203 of the communication controller 102 updates the price of the product master stored in the storage unit 204 to the price after the price reduction calculated in step S1203. At the same time, in order to update the contents of the product master stored in the storage unit in the same manner, a change request including the price information after the price reduction and the shelf label ID is transmitted to the server 101 (step S1204). Subsequently, the control unit 203 of the communication controller 102 transmits a changeable message and price information after the price reduction to the control unit 603 of the handy terminal 105 (step S1205), and ends the process. If it is determined in step S1202 that there is no change authority, the control unit 203 of the communication controller 102 transmits an unchangeable message to the control unit 603 of the handy terminal 105 (step S1206), and the process ends.

  Next, processing of the shelf label 104 will be described. The receiving unit 502 of the shelf label 104 receives the price information after the price reduction from the communication unit B 606 of the handy terminal 105. The control unit 504 of the shelf label 104 changes the display content of the display unit 503 based on the price information after the price reduction received by the receiving unit 502.

  In this embodiment, the display content of the shelf label 104 is changed from the handy terminal 105, but the display content of the shelf label 104 can be changed from the communication controller 102. That is, instead of the communication controller 102 transmitting a display content changeable message to the handy terminal 105 in step S804, the communication controller 102 transmits the changed price information to the shelf label 104. Then, the price information transmitted from the communication unit 207 of the communication controller 102 is received by the receiving unit 502 of the shelf label 104, and the control unit 504 changes the price information displayed on the display unit 503 based on the price information. May be.

  According to the above procedure, the price reduction price is automatically calculated, and the display of the electronic shelf label can be changed.

  The example of the procedure for changing the display content of the shelf label 104 using the handy terminal 105 has been described above. However, after the display content of the shelf label 104 is changed in step S706 or the change information is received in step S702. After that, information regarding the price information change (price information, identification ID or product ID, and terminal identification number of the handy terminal 105) is transferred from the handy terminal 105 to an accounting POS register (not shown) installed in a store or the like. Information), and the POS register may change the price information of the product stored in the device for accounting processing. Further, along with the change, the POS register may be requested to change the product master of the server 101.

  In general, there are many cases where a POS system (a system including a server 101 and a POS cash register) has already been introduced in a store. When an electronic shelf label system such as a communication controller 102, a relay station, a shelf label 104, a handy terminal 105, a display 106, etc. is additionally introduced into an existing server 101, the connection between the server 101 and the communication controller 102, cooperation of applications and data, etc. There are many technical difficulties. Therefore, in many cases, a new POS system that can be connected to the electronic shelf label system is introduced to introduce the electronic shelf label system. However, since this is costly, there are cases where the POS system and the electronic shelf label system are introduced into the store in an independent state.

  According to the present invention, since the price information change information is transmitted from the handy terminal 105 to the POS register, the price information stored in the POS register is changed to the POS register even if the POS system and the electronic shelf label system are independent. Can be made. Furthermore, the information regarding the price information change can be transmitted to the server 101 through the POS register and reflected.

  If the handy terminal 105 is equipped with a printing unit 610, in addition to discount information, information related to price information change is printed (printed as character information or coded as a barcode or QR code). Printing) and reading it to a POS register. Then, based on the information regarding the price information change, the POS register may change the price information stored for the accounting process. Further, the POS register may be requested to change the product master of the server 101.

  By doing so, the customer brings the product with the discount sticker to the POS register, and when the accounting process of the product is performed at the POS register, information on the price information change of the product is stored in the POS register. And can be reflected in the server 101.
