And the acquired merchandise information is input into the electronic price tag apparatus 7 via a communication part.

  Next, the control configuration of the product information display system 1 will be described with reference to the control configuration diagram of FIG. First, the control configuration of the electronic price tag device 7 will be described.

  The electronic price tag device 7 includes a display 32, a price update button 12, a communication interface 31, a connection interface 39, a ROM 34 (Read Only Memory), a RAM 35 (Random Access Memory), a main memory 37, and a processing operation unit 36. They are connected by a bus 33. The ROM 34 stores a control program and controls processing operations in the electronic price tag device 7. The main memory 37 has a product information storage unit 91 and a group information storage unit 92.

  The communication interface 31 is for performing wireless communication with the antenna 3 installed in the store, and includes a wireless communication circuit (not shown). In addition, it is good also as a structure which replaces with wireless communication and communicates by infrared rays.

  The merchandise information storage unit 91 in the main memory 37 stores a display price 74 and inventory management information 86 extracted from the display control data. The group information storage unit 92 stores a group ID 84 (group information) to which the group belongs (group information storage unit).

  The control program controls display processing on the display 32 and price update instruction processing to the host device 5 by the processing calculation unit 36. In the display process, the display price 74 and the inventory management information 86 are displayed on the display 32 based on the display control data received from the host device 5. When receiving the display control data from the host device 5, the electronic price tag device 7 extracts the display price 74 and the inventory management information 86 from the display control data and stores them in the product information storage unit 91. Then, the electronic price tag device 7 reads the display price 74 and the inventory management information 86 from the product information storage unit 91 and displays them on the display 32.

  The price update instruction process is to update the display price 74 of all the electronic price tag devices 7 belonging to the same group in the product master 71. When the price update button 12 is pressed, the electronic price tag device 7 generates price update instruction information including the group ID 84 to which the electronic price tag button 12 belongs, and transmits it to the host device 5 (price update instruction means). Based on the received price update instruction information, the host device 5 updates the display price 74 of the group to which the electronic price tag device 7 of the product master 71 belongs (details will be described later).

  The electronic POP device 8 includes a display 42, a connection interface 49, a DIP switch 23, a ROM 44, a flash memory 47, a RAM 45, and a processing operation unit 46, which are connected to the internal bus 43. The ROM 44, the flash memory 47, the RAM 45, the processing operation unit 46, and the internal bus 43 are accommodated in the control box 24 described above. The ROM 44 stores a control program, and the electronic POP device 8 controls various processes based on the control program. The flash memory 47 stores a plurality of display data files to be displayed on the display 42.

  As shown in FIG. 5, the flash memory 47 stores a POP code 83 and a display data file in association with each other, and this POP code 83 corresponds to each position (number) of the DIP switch 23. That is, the display data file can be easily selected by operating the DIP switch 23. In the example of the figure, the number “1” of the electronic POP device 8 corresponds to the POP code 83 “HD01” and indicates the display data file “store manager recommended product”, and the number “2” corresponds to the POP code 83 “HD02” and is displayed. The data file “time service product” is shown, and the number “3” corresponds to the POP code 83 “HD03” and the display data file “today sale product”. Then, for example, when the DIP switch 23 is operated to set the numeral “1”, the processing calculation unit 46 reads the POP code 83 “HD01” from the flash memory 47 according to the control program in the ROM 44, and displays the POP code on the display 42. Display file data “store manager recommended product” corresponding to 83 “HD01” is displayed.

  The handy terminal 6 includes a display 52, input keys 58, a communication interface 51, a ROM 54, a RAM 55, a scanner 59, and a processing operation unit 56, which are connected to an internal bus 53. The ROM 54 stores a control program, and the handy terminal 6 controls various processes based on the control program.

  In addition to the product information generation process for generating product information from the barcode attached to the sold product, the control program performs a transmission instruction process for causing the electronic price tag device 7 to transmit price update instruction information to the host device 5 by the processing calculation unit 56. It is something to control. In the product information generation process, the handy terminal 6 analyzes the barcode read by the scanner 59 to generate product information and displays it on the display 52. The input key 58 is provided with a price update key. Instead of pressing the price update button 12 of the electronic price tag device 7, the price update key is pressed to transmit the transmission instruction information to the electronic price tag device 7. Then, the price update instruction information is transmitted from the electronic price tag device 7 to the host device 5 (transmission instruction means). That is, the price update process of the product master 71 by the host device 5 can be instructed from both the electronic price tag device 7 and the handy terminal 6.

  The host device 5 includes an input device 68, a display 62, a communication interface 61, an input / output interface 69, an internal bus 63, a CPU 66 (Central Processing Unit), a ROM 64, a RAM 65, and an HDD 67 (Hard Disk Drive). The HDD 67 stores a product master 71. The ROM 64 stores a control program and controls various processes based on the control program.

  In the product master 71, as shown in FIG. 6, a product code 72, a product name 73, a display price 74, a normal price 75, a special price 76, a time service price 77, a recommended price 78, a stock quantity 79, and a sales record 80 last week. This week's sales record number 81, price tag ID 82, POP code 83, and group ID 84 are stored in association with each sale product. The display price 74 indicates the price that is currently displayed on the electronic price tag device 7 for the product for sale. The regular price 75 indicates the fixed price of the product for sale. The special price 76 indicates 3 discounts of the normal price 75, the time service price 77 indicates 2 discounts of the normal price 75, and the recommended price 78 indicates 1 discount of the normal price 75. The price tag ID 82 is used by the host device 5 to identify the electronic price tag device 7 and is used for communication with the electronic price tag device 7.

  The POP code 83 specifies a display data file displayed on the electronic POP device 8 attached to the electronic price tag device 7. In the example of FIG. 6, the sales product “Sanma” is the POP code 83 “HD02”, and “time service product” is displayed on the corresponding electronic POP device 8. Similarly, the sales products “oyster”, “cabbage”, and “pumpkin” have a POP code 83 “HD01”, “store manager recommended product” is displayed on each corresponding electronic POP device 8, and “orange” has a POP code 83 “HD03”, and “today's sale” is displayed on the corresponding electronic POP device 8.

  The POP code 83 “HD01” corresponds to the recommended price 78, the POP code 83 “HD02” corresponds to the time service price 77, and the POP code 83 “HD03” corresponds to the special price 76. That is, in the example of FIG. 6, the sales product “Sanma” is the POP code 83 “HD02”, and the time service price 77 is displayed in the display price 74. Similarly, the sales products “oyster”, “cabbage”, and “pumpkin” have a POP code 83 “HD01”, the recommended price 78 is displayed at the display price 74, and the sales product “Orange” has a POP code 83 “HD03”. Yes, a special price 76 is displayed as the display price 74.

  The group ID 84 indicates the group to which the electronic price tag device 7 corresponding to the sales product belongs. In the example of FIG. 6, the sales products “sanma” and “oyster” belong to the group ID 84 “005” indicating the fresh fish section, and the sales products “cabbage”, “pumpkin”, and “orange” have the group ID 84 indicating the fruit and vegetable section. It indicates that it belongs to “001”.

  The control program performs display control of the electronic price tag device 7 based on the price updated product master 71 in addition to price update processing for updating the price of the product master 71 based on the update instruction information received from the electronic price tag device 7. The display control process for performing the above is controlled by the CPU 66. In the price update process, when the host device 5 receives the price update instruction information from the electronic price tag device 7, the group ID 84 is extracted from the price update instruction information, and the price tag IDs 82 of all the electronic price tag devices 7 in the same group in the product master 71. And a transmission request for the POP code 83 is made to each electronic price tag device 7. When the host device 5 acquires the POP code 83 from each electronic price tag device 7, the host device 5 rewrites the POP code 83 of the product master 71 with the newly acquired POP code 83. Then, the host device 5 determines a corresponding price (hereinafter referred to as a selection price) based on the rewritten POP code 83, and displays the display price 74 of each electronic price tag device 7 in the same group in the product master 71. Rewrite to the selected price (rewrite means). For example, when the operator presses the price update button 12 of the electronic price tag device 7 corresponding to the sale product “cabbage”, the display price 74 of “cabbage” and “pumpkin” that are the same group becomes the recommended price 78 and “orange”. The displayed price 74 is rewritten to the special price 76, respectively.

  In the display control processing, when the price of the product master 71 is updated by the host device 5, the display price 74 and the inventory management information 86 after rewriting are extracted from the product master 71, and display control data is generated based on these. The host device 5 transmits the generated display control data all at once to the group of electronic price tag devices 7 that requested the price update instruction (display control data transmission means). Then, each electronic price tag device 7 that has received the display control data displays the updated display price 74 on the display 32.

  Next, the flow of display control processing in the product information display system 1 will be described with reference to the flowchart of FIG.

  First, when the operator operates the DIP switch 23 of the electronic POP device 8 to change the display data file and presses the price update button 12 of the electronic price tag device 7 or the price update key of the handy terminal 6 (S01), The price tag device 7 generates price update instruction information from the group ID 84 stored in the main memory 37 and transmits it to the host device 5 (S02). The host device 5 extracts the group ID 84 from the received price update instruction information, and sends a transmission request for the POP code 83 to all the electronic price tag devices 7 belonging to the same group (S03). When the host device 5 acquires the POP code 83 from each electronic price tag device 7, it rewrites the POP code 83 of the same group of the product master 71 to the acquired POP code 83, respectively (S04).

  Then, the host device 5 determines a selection price based on each POP code 83 (S05), and rewrites the display price 74 included in the same group of the product master 71 to a selection price corresponding to each POP code 83 ( S06). The host device 5 generates display control data based on the rewritten display price 74, and transmits it all at once to all the electronic price tag devices 7 belonging to the same group (S07). The electronic price tag device 7 switches the display on the display 32 based on the received display control data (S08).

  According to the above configuration, the display price 74 of the electronic price tag device 7 stored in the product master 71 when the electronic POP device 8 is mounted is acquired from the electronic POP device 8 in accordance with an instruction from the electronic price tag device 7 installed in the sales area. Since the price corresponding to the additional information is rewritten based on the additional information, there is no deviation between the content displayed on the electronic POP device 8 and the display price 74 of the electronic price tag device 7. For this reason, the operator does not need to reciprocate between the installation location of the host device 5 and the sales area. Further, by managing the sales area as a group, the sales stored in the merchandise master 71 can be performed according to an instruction from any one electronic price tag device 7 in the sales area without giving an instruction for each electronic price tag device 7. The display price 74 of the electronic price tag device 7 to which all the electronic POP devices 8 in the area are attached can be changed. In addition, the group here is not limited to the case where each sales area is divided, and the entire sales store may be a single group. Further, the electronic price tag device 7 is not limited to the place of installation, and the electronic price tag device 7 may be grouped according to the type of product sold.

  The rewriting of the display price 74 in the product master 71 is obtained by obtaining the discount rate of the sales product from the electronic POP device 8 instead of the configuration of rewriting the display price 74 based on the POP code 83 acquired as described above. The display price 74 may be rewritten based on this discount rate. In this case, the POP code 83, the display data file, and the discount rate are stored in association with each other in the flash memory 47 of the electronic POP device 8 (see FIG. 8). Then, the host device 5 requests transmission of a discount rate instead of requesting the electronic price tag device 7 to transmit the POP code. The host device 5 acquires the discount rate from the electronic POP device 8 via the electronic price tag device 7 and rewrites the display price 74 to a calculated price that is the product of the normal price 75 of the product master 71 and the discount rate. In this case, since the information on the special price 76, the time service price 77, and the recommended price 78 is not necessary in the product master 71, the capacity can be reduced.

  As described above, instead of the configuration in which the handy terminal 6 transmits the price update instruction information to the host device 5 to the electronic price tag device 7, the price update instruction information is directly sent from the handy terminal 6 to the host device 5. It is good also as a structure which transmits. In this case, a group whose price is to be updated is input using the input key 58, and the price is updated by the host apparatus 5 by pressing the price update key. Thereby, since it is not necessary to provide the price update button 12 in the electronic price tag device 7, the electronic price tag device 7 can have a simple device configuration.

  As described above, the electronic POP device 8 has been described as an example in the present embodiment. However, the electronic POP device 8 is not limited to the electronic POP device 8 and may be a POP display tool 95 that displays additional information. In this case, as shown in FIG. 9, the POP display device 95 is a thin plate material such as a plastic material, and has a rectangular mounting opening 96 for mounting the electronic price tag device 7 in the center. Further, the POP display tool 95 has a concavo-convex part 97 formed at the upper edge of the mounting opening 96, and is used when identifying the type of additional information written on the POP display tool 95. The electronic price tag device 7 is provided with a plurality of detection switches 98 (three in the figure) on the top, and the electronic price tag device 7 is mounted in the mounting opening 96 of the POP display device 95, thereby detecting the detection switch 98 on the uneven portion 97. Is pressed to identify additional information of the attached POP display tool 95. Then, the host device 5 updates the product master 71 based on the additional information acquired from the electronic price tag device 7.
