5 is a diagram showing an example of a functional block diagram of an electronic shelf label 90, and FIG. 10 is a front view showing an example of the electronic shelf label 90. As shown in both figures, the electronic shelf label 90 has a CPU 91, a ROM 92, a RAM 93, a display unit 94, and a communication unit 95. These components are connected to each other via a communication line 96 such as a bus, and a separate battery 97 is also built in. The CPU 91 controls the operation of the electronic shelf label 90 by executing a control program stored in the ROM 92. The ROM 92 stores various information such as the control program. The RAM 93 temporarily stores various information. The display unit 94 is, for example, a liquid crystal display, and displays information such as the price of the product placed on the shelf on which the electronic shelf label 90 is installed to the customer. The communication unit 95 is a communication interface for communicating with the shelf label management device 50 and the like via the transceiver 80. For example, infrared communication is used as a communication means between the communication unit 95 and the transceiver 80, but various other communication means may also be used. As shown in FIG. 10, the display screen 94 of the electronic shelf label 90 displays "SALE" for sales promotion, the product name, the current selling price, and the like. The display screen 94 is preferably in color for effective sales promotion. A lamp 99 is provided at a predetermined position (upper corner) of the display screen 94, which can be turned on when a store clerk wants to change the electronic shelf label 90 to a product shelf label, for example, to facilitate the exchange. An identification code (barcode) 98 is displayed at a predetermined position (lower center) of the display screen 94 to distinguish the electronic shelf label 90 from other electronic shelf labels 90. The means for identifying the electronic shelf label 90 may be the electronic tag or the character string or number itself. In that case, the handheld terminal 85 may be provided with an electronic tag reader or an imaging means such as a CCD camera. Depending on the space and face of the display area, vertical and horizontal types and even multiple sizes are available.

Although not shown, the handheld terminal 85 has a CPU, a ROM, a RAM, a display operation unit, and a communication unit, and these components are connected to each other via a communication line such as a bus, and is configured to have a separate built-in battery. The CPU controls the operation of the handheld terminal 85 by executing a control program stored in the ROM. The ROM stores various information such as the control program. The RAM temporarily stores various information. The display operation unit is, for example, a liquid crystal display, and is used to display various instructions to the worker carrying the handheld terminal 85 and to link the electronic shelf label 90 with the location of the product or shelf. The communication unit is a communication interface for communicating with the shelf label management device 50 and the like via the transceiver 80. The communication means of the communication unit of the handheld terminal 85 may be any means such as wireless LAN or infrared communication, and may use a communication means and communication band different from those of the electronic shelf label 90. In addition, the handheld terminal 85 may be batch processing rather than real-time processing.

Next, the operation of the electronic shelf label management system 1-1 will be described, starting with the prerequisite operations.
When introducing electronic shelf labels (ESLs) 90, if the same number of electronic shelf labels 90 as the number of products handled in a store are purchased, the investment amount becomes enormous, so generally, not all of them are purchased. For example, suppose 3,500 electronic shelf labels 90 are purchased. Then, first, a surplus is secured for new products, etc. For example, 100 units are secured as surplus, and the remaining 3,400 units are allocated to each department, etc.

The person in charge determines the sales price change history (hereinafter referred to as "sales change history") and the change history of required display information other than the sales price (hereinafter referred to as "required display information change history") for any past period from the sales management system, sales planning management data, etc. From the results, the target products for which electronic shelf tags 90 are to be installed are selected. The allocation may be made automatically according to the number of electronic shelf tags 90 allocated to each department/category unit, starting from the top products with the most changes in the sales change history and required display information change history.

Next, the person in charge installs electronic shelf labels 90 on the shelves on which the selected target products are placed. This installation is performed by category, by rail of the product shelf, or by face. Each electronic shelf label 90 has a shelf label identification number, and can be identified by attaching an identification code 98 or an electronic tag. Specifically, the electronic shelf label 90 is installed as follows.
(1) The product identification number (barcode such as EAN, UPC, ITF, or electronic tag) data is read and input using a handheld terminal 85 or the like.
(2) The identification number of the electronic shelf label 90 is read from the identification code 98 (or electronic tag, character string, or number) by the handheld terminal 85 or the like and input.
(3) An operation for linking the product with the electronic shelf label 90 is performed. The linking operation is performed by pressing the confirmation button on the operation surface of the handheld terminal 85, for example.

In order to confirm the linking operation between the above-mentioned products and the electronic shelf labels 90, for example, the shelf label management device 50 may acquire the status of each electronic shelf label 90 via a transceiver 80 (a relay device such as an access point, and the communication means may be any means such as WiFi, infrared communication, or a beacon) that communicates with the electronic shelf labels 90, and compare the acquired status of the electronic shelf labels 90 with the linking confirmation information acquired from the handheld terminal 85.

On the other hand, in the case of a new store (a newly opened store), product shelf tags (so-called price cards) are issued and placed near each product. In addition, in the case of a new store, special plans such as a special sale for the new store opening or special gifts are planned, so POP advertisements are issued and attached to the sales locations of the products. FIG. 11 is a diagram showing an example of a POP advertisement 75. As shown in the figure, the POP advertisement 75 displays "SALE, our store's best recommendation!" for sales promotion on a sheet (paper medium), as well as the product name and current selling price. This POP advertisement 75 is preferably displayed in color for effective sales promotion. The POP advertisement 75 printed in this way is placed, for example, in a specified position on a display shelf near the product. It is desirable to display an identification code 76 on the POP advertisement 75 so that the POP advertisement can be distinguished from other POP advertisements. In this way, electronic shelf tags and product shelf tags (including POP advertisements) are prepared.

In the above, electronic shelf tags 90 or product shelf tags are issued by linking them to products and allocating them to each product. However, when multiple identical products are displayed, such as in a sales area within a store, the products and display locations (locations) may also be linked and matched. The location may be determined based on position information from the handheld terminal 85, a barcode or character string affixed to the product shelf in advance, or by selecting the display location from a pull-down menu on the handheld terminal 85, or by manual input.

Furthermore, it may be possible to link the promotion plan management number in the promotion master or sales plan master. By using the promotion number or promotion plan name, it is possible to assign and create multiple electronic shelf labels 90 and POP advertisements for the same product. This allows the preparation and installation of electronic shelf labels 90, product shelf labels, promotional POP advertisements, etc. in the store to be performed quickly and accurately. Note that the linking operation using the handheld terminal 85 may be performed in multiple operating methods according to the purpose of the work, such as by product specification or display location.

Next, we will explain how to switch between electronic shelf tags 90 and product shelf tags in an operating store. The product sales change history, required display information change history, and sales promotion plan history described above are stored and managed as data on the hard disk 55 of the shelf tag management device 50.

Figure 6 is a diagram showing an example of a shelf label management screen G1 displayed on the display unit 54 of the shelf label management device 50. As shown in the figure, the shelf label management screen G1 displays a department setting field G11, an electronic shelf label usage count display field G12, a period setting field G13, a shelf label condition setting field G15, a judgment target selection field G17, a display target selection field G19, a display method selection field G21, a product field G23, an output button G25, a confirmation button G27, a switch product count field G29, and the like.

The department setting field G11 is a field for selecting a department to be displayed in the product field G23. For example, a department classified according to the nature of the product or the sales form, such as the produce department, the fish department, the meat department, the prepared food department, and the daily necessities department, is selected and displayed. In the illustrated example, the produce department is selected. The electronic shelf label usage display field G12 displays the number of electronic shelf labels 90 currently in use (67 in the figure) out of the electronic shelf labels 90 assigned to each department (120 in the figure). The period setting field G13 is a field for setting a period for determining whether to attach or remove the product. For example, the start date and time of the period is input in the field G131 on the left side of the figure, and the end date and time of the period is input in the field G133 on the right side of the figure. The display target setting field G15 is a field for specifying the display target to be displayed in the product field G23. It is a field for setting one of the following: fixed product shelf label, fixed electronic shelf label, fixed unspecified product (such as new products or products not on display), normal (target item for which attachment or removal is determined), etc. In the figure, normal is set.

The judgment target selection field G17 is a field for selecting whether to extract targets for installation and removal using only price changes, extract targets for installation and removal using other than price changes, or extract targets for installation and removal using both, and in the figure, it is selected to extract targets for installation and removal using price changes. The display target selection field G19 is a field for selecting whether to display mutual changes between electronic shelf labels 90 and product shelf labels (ALL), to display only cases where the electronic shelf labels 90 are changed to product shelf labels (ESL ⇒ POP), or to display only cases where the product shelf labels are changed to electronic shelf labels 90 (POP ⇒ ESL), and in the figure, it is selected to display mutual changes. The display method selection field G21 is a field for selecting whether to display (sort) in ascending or descending order when sorting in order of high or high frequency of installation and removal conditions, and in the figure, it is selected to display in ascending order. The product field G23 is a list of products calculated according to the above conditions. The product column G23 has columns for number (No.), PLU, product name (product name), specification, sales change (number of times the selling price has been changed), change (attachment/removal), and confirmation. The confirmation column indicates whether the product is to be changed or not, and confirmed products are subject to update. Confirmed or unconfirmed can be selected by pressing the confirmation column corresponding to each product. In addition, pressing the confirmation button G27 switches all products in the product column G23 displayed in a list to confirmed. Pressing the output button G25 outputs (transmits) change data for confirmed products to the handheld terminal 85 or the printer 70 via the output content screen G3 shown in FIG. 7 described below. This allows the electronic shelf tag 90 or product shelf tag to be changed using the display screen of the handheld terminal 85 or the form output from the printer 70.
Furthermore, even if this operation is not performed, if the conditions for the change are set in advance, for example, when a menu is selected and the screen is displayed, if the initial value is set in advance, such as setting the initial value of a selection field other than the display content that determines the display data based on the department setting, specifically the judgment target selection field G17 to the selling price change, then by selecting a department, a judgment can be made automatically for a period of one month from the current day and one month from the previous month.

If the quantity of electronic shelf labels 90 used in a department can be changed at any time, it is convenient when adjusting surpluses or when quantity adjustments between departments occur. In addition, when calculating the top list displayed in the above-mentioned product column G23, it may be possible to set for each product, such as not allocating electronic shelf labels 90 or using only product shelf labels. In that case, the product is excluded when generating the top list. Furthermore, by setting specific conditions, it is possible to switch from electronic shelf labels 90 to product shelf labels. For example, it is possible to set conditions such as forcibly allocating electronic shelf labels 90 that have been allocated to a department that has not changed its sales price within a certain period of time to another department or to allocate them for surplus use. Note that although a department is used here, it may also be a medium or small classification.

6, only the selling price change is used in the judgment target selection field G17 to extract the target for attachment/removal, but other than the selling price change or both may be used, that is, for example, as an example other than the selling price change, the necessity of the electronic shelf label 90 may be judged based on the product characteristics. For bare-sold products such as fruits and vegetables and fresh fish, information other than the selling price (essential display information) such as the place of origin and producer frequently changes, so it is more useful to use the electronic shelf label 90. This is because it is inefficient in terms of labor and cost to issue POP advertisements and product shelf labels every time the place of origin changes. On the other hand, for departments such as stationery and daily necessities, the selling price change and other essential display information hardly change, so it is possible to exclude them from the targets of the electronic shelf label 90 from the beginning so that the electronic shelf label 90 is not assigned to them.
Furthermore, products whose display information has been changed may be treated as target products. Specifically, when an allergy label is added to the electronic shelf label 90, or when a POP larger than a normal price card is used to increase customer appeal, the electronic shelf label 90 may be removed under the opposite condition to the above.

Also, products that are the subject of a sales promotion plan may be forcibly targeted for POP advertisements. However, electronic shelf labels 90 may be installed in normal display locations, and separate POP advertisements may be issued in sale or promotional sales areas. In this case, the need for electronic shelf labels 90 may be determined by the combination of product and sales promotion plan, or the combination of product and location.

Figure 7 is a diagram showing an example of the output content screen G3 displayed on the display unit 54 of the shelf label management device 50. As shown in the figure, the output content screen G3 displays a department column G31, a display location column G33 to be switched to, an output target column G35, a send button G37, and an issue button G39.

The department field G31 displays the department of the product to be replaced, and in this example, displays the fruit and vegetable department. The changeover target display location field G33 displays the first and last points of the display location to be replaced. The 11th line 04 shelf 99th row 99th column means up to the last row and column of the 11th line 04 shelf. The output target field G35 is a field in which it is possible to select whether to output only the unupdated part or to output all of the updated and unupdated parts. Although not shown in the figure, the output target field G35 may be provided with a display of a difference in addition to the unupdated part and all. The difference is for outputting not only the unupdated part but also new unupdated parts that have occurred during the replacement work. The send button G37 is a button that enables the handheld terminal 85 to receive the data, and is a button that sends the data to a database in the shelf label management device 50, the store controller 10, or a separate file server (including the cloud). The issue button G39 is a button that outputs the data to the printer 70.
This makes it efficient to use the instruction list output from the handheld terminal 85 and the printer 70 in combination, or to switch between them independently. Also, the instruction list is useful when multiple people are working simultaneously, as it allows the output range to be determined. It is also possible to make it possible to select multiple ranges for the display location. When specifying multiple ranges, for example when performing an operation to add an input field, it is easier to operate if the location number in the end field at the top is automatically entered in the start field. It is also possible to make the data receivable by the handheld terminal 85 when the Confirm button G27 in Figure 6 is pressed, without using Figure 7 in particular.

8 is a diagram showing an example of a switching progress screen G5 displayed on the display unit 54 of the shelf label management device 50. As shown in the figure, the switching progress screen G5 displays a department field G51, a switching target field G53, a progress ratio display field G55, a progress display target selection field G57, and a product information display field G59. The department field G51 displays the department of the product for which the progress is to be displayed, and in this example, the produce department is displayed. The switching target field G53 displays whether to switch from the electronic shelf label 90 to the product shelf label, to switch from the product shelf label to the electronic shelf label 90, or to attach a new shelf label, and in this example, a product to be switched from the product shelf label to the electronic shelf label 90 is selected. The progress ratio display field G55 displays the percentage of the switching progress. The progress display target selection field G57 selects whether the product to be displayed in the product information display field G59 is a product that has been replaced, a product that has not been replaced, or both, and in this example, it is selected to display both. The product information display field G59 displays the display location, PLU, product name, person in charge, installation, and communication information for each product selected according to the various conditions described above. Installation here indicates whether installation of the electronic shelf label 90 in the display location has been completed, regardless of whether communication with the transceiver 80 has been completed. Communication indicates whether communication between the electronic shelf label 90 and the transceiver 80 has been completed.

When switching shelf tags, various conditions such as the department and an arbitrary (predetermined) period are entered into the shelf tag management screen G1 shown in FIG. 6. Next, the output button G25 on the shelf tag management screen G1 is pressed to display the output content screen G3 shown in FIG. 7. After the department and display location for the replacement are confirmed on this output content screen G3, the data is sent to the handheld terminal 85 or printer 70 so that it can be used.

Then, using the display screen of the handheld terminal 85 or an instruction sheet (document) printed by the printer 70, the person in charge replaces the product shelf label with the electronic shelf label 90, or replaces the electronic shelf label 90 with a product shelf label, or in the case of a new product, attaches a new product shelf label or electronic shelf label 90. At this time, the number of shelf labels to be switched and the location may be set in multiple locations so that multiple workers can be engaged in the switching work. A specific explanation is given below.

First, we will explain the case where the electronic shelf label 90 is switched to a product shelf label. In this case, a product shelf label (including a price card and a POP advertisement) is issued for the product to be switched to. The issuing unit may be a department, a display location, etc.

The issued product shelf label is attached at the sales floor of the store, and the electronic shelf label 90 is collected. In the case of an instruction sheet (document), the electronic shelf label 90 is removed at the display location of the product, and the product shelf label is attached. In the case of using a handheld terminal 85 or the like, the process may be completed by comparing the identification information (identification code 98, etc.) of the electronic shelf label 90 with the identification information (identification code 76, etc.) on the product shelf label, or by reading a location barcode, etc., if there is one at the display location. In addition, when the switching operation is performed quickly after closing time, the display section 94 of the electronic shelf label 90 may be blanked (erased) in advance, a character string or mark that can be identified as the target for replacement may be displayed, or if the electronic shelf label 90 is equipped with a lamp 99, the lamp 99 may be turned on in order to easily identify the electronic shelf label 90 to be replaced. In the case where the lamp 99 can be switched to two or more colors, or if two or more lamps 99 are equipped, the color of the light may be changed to a special sale color, or the light may be turned on or blinked to make it easier to identify.

When performing the switching work as described above, for example, by using a switching progress screen G5 as shown in FIG. 8 (the screen in FIG. 8 shows the state when switching from product shelf labels to electronic shelf labels 90, but the opposite state is also possible), the progress of the electronic shelf label 90 collection operation can be confirmed and the work can be prevented from being forgotten. It is also possible to grasp the identification information of the collected electronic shelf labels 90, and it is also possible to select the electronic shelf label 90 to be used next based on the remaining battery power of each electronic shelf label 90, etc.

Next, a case where the product shelf label is switched to the electronic shelf label 90 will be described. In this case, the electronic shelf label 90 to be installed is taken to the product display location specified by the instruction sheet or the handheld terminal 85. At this time, the electronic shelf label 90 may be switched to new product information in advance, or may be in the initial value state.

Next, the product shelf labels in the specified product display locations are removed and electronic shelf labels 90 are installed. Then, the identification information (such as the identification code 98) of the electronic shelf labels 90 and the product or location identification information are entered, and the replacement operation is complete. The display information of the electronic shelf labels 90 may be updated after all electronic shelf labels 90 have been installed, or may be updated each time an electronic shelf label 90 is installed. Once the display information of all electronic shelf labels 90 has been rewritten, the work is complete.

Next, we will explain sales promotion plans (sales promotion plans). Sales can be set by product, category, or department. When setting sales by category or department, they can be set by excluded products or subcategories. For example, all produce can be set at 10% off, but Chinese cabbage can be excluded. A period (start and end dates) must be set. When multiple sales promotion plans apply, possible methods include prioritizing each plan, giving priority to plans with similar start dates, or if the start dates are the same, giving priority to plans with similar end dates (shorter), or giving priority to the lowest price.

In addition, even if it is not a special sale, if the price is changed for a long period such as one month, the period price can be set in the sales planning master or product master. In the case of monthly special offers, if it is subject to a sales plan it will not be subject to the electronic shelf tag 90, but since it cannot be checked in the period price setting in the product master or the like, it is also possible to determine whether it is subject to the price setting by period (even a single day). It is easy to see that electronic shelf tag 90 is not required for items whose price does not change from month to month, so this can be incorporated into the logic when generating the top list.

Next, if the electronic shelf tag 90 does not have an identification code, the following operation is performed. First, the shelf tag management device 50 sets the allocated number and spare number of electronic shelf tags 90 for each department and category. The spare number is the number of electronic shelf tags 90 that is manually allocated to new products, etc.

The installation/removal screen G7 of the shelf label management device 50 in FIG. 12 is a screen for grasping the product master registration status for each intermediate category and the number of tasks to be performed for installation/removal. This installation/removal screen G7 displays the number of electronic shelf labels introduced column G71, the number of allocations for each intermediate category column G73, the number of displayed products column G75, and the number of products to be installed/removed column G77. The maximum number of electronic shelf labels to be installed is the number displayed in the number of electronic shelf labels introduced column G71 minus the number of spares. This installation/removal screen G7 has a function of printing a product shelf label (POP) for a product to be removed when the number of products to be installed/removed for each intermediate category column G77 is pressed. After issuing the product shelf label (POP), the electronic shelf label 90 of the target product is removed according to the issued product shelf label (POP).
In actual operation, there are cases where multiple products are displayed, or multiple electronic shelf tags 90 are used for one product due to display face and space restrictions. Therefore, the removal work is not one work per product. Note that the number of work steps is two because two identification numbers of the electronic shelf tags 90 are linked to the product.
When attaching electronic shelf labels 90, if the worker can arbitrarily decide the number of electronic shelf labels 90 to be attached, it is possible to set multiple electronic shelf labels for one product. Specifically, the barcode of the product is scanned and the identification information of the electronic shelf label 90 is scanned. If the product code and electronic shelf label identification information are the same, an error is reported, and if the electronic shelf label identification information is different, a message such as "A second electronic shelf label will be attached to this product. Is this OK?" is displayed and additional settings can be made.
If the department plans to use the electronic shelf label in advance, the department can set the start date of use or prohibit transfer between departments, and notify the department of the start date to prevent the department from being affected.

Next, the operation on the handheld terminal 85 will be described. FIG. 13 is a diagram showing an example of an installation/removal operation screen G9 displayed on the display operation section of the handheld terminal 85 during the installation/removal work of the electronic shelf label. This installation/removal operation screen G9 displays a list of products for which the electronic shelf label 90 is to be installed/removed, for each medium classification. This installation/removal operation screen G9 displays a manufacturer name (supplier) display field G91, a product identification code/product name field G93, a display standard field G95, and a work check field G97. The work check field G97 displays whether installation or removal is to be performed, and whether the installation/removal work has been completed, and a check ("R") indicates that the installation/removal work has been completed (checked). This makes it possible to perform the installation/removal work easily and reliably.

This installation/removal operation screen G9 may display any other information that may be useful for the replacement operation, such as the selling price. If the electronic shelf label 90 does not have an identification code, the user may press the operation check field G97 on the installation/removal operation screen G9 or perform a confirmation operation by moving the cursor. If the product has a product code (barcode), the product code can be scanned to mark the product as having been checked. If the electronic shelf label 90 has an identification code 98, the identification code 98 can be read to mark the product as having been checked. If "Removal" (not shown) in the operation check field G97 is checked or the target product code is scanned, the display on the electronic shelf label 90 is cleared. In this way, if the electronic shelf labels 90 were introduced at different times, either one can be handled. If an individual identification code is attached, the replacement operation can be performed even if there are electronic shelf labels 90 that do not have an identification code attached, and progress and completion can be managed, so that the operation can be performed without any mistakes. As described above, the operation of switching between the electronic shelf label 90 and the product shelf label can be easily performed by anyone without any mistakes.

In addition, in the handheld terminal 85, a linking operation (linking operation) can be performed by inputting the product code and the identification code of the electronic shelf label 90. FIG. 14 is a diagram showing an example of a linking operation screen G11 for linking the product code and the identification code of the electronic shelf label 90. As shown in the figure, information is input into the display location field G111, the product code field G113, and the identification code field G115 of the electronic shelf label 90, respectively, to perform the linking operation and transmit it to the shelf label management device 50. The electronic shelf label 90 that has completed the linking communicates with the transceiver 80. The electronic shelf label 90 periodically communicates with the transceiver 80, thereby updating the display content of the electronic shelf label 90. In other words, the electronic shelf label 90 that has been linked automatically connects to the transceiver 80 and displays data corresponding to the newly linked product information. As the timing of communication, the transceiver 80 can also be controlled by an operation from the handheld terminal 85.

If the display shelf (display location) has an identification code and the electronic shelf label 90 and POP are managed in association with the product code, the display can be updated in the same way by linking the identification code of the display location with the identification code of the electronic shelf label 90. Furthermore, the linking operation between the product and the electronic shelf label 90 can also be performed on a separate screen. The electronic shelf label 90 can also be removed (the linking operation is cleared) to use it as a spare electronic shelf label 90.

Fig. 15 is a diagram showing an example of an electronic shelf label management menu display field G13 displayed on the display operation section of the handheld terminal 85. As shown in the figure, the electronic shelf label management menu display field G13 displays an electronic shelf label creation field G131, an electronic shelf label deletion field G133, etc., and by pressing any of the fields, it is possible to perform linking when setting up an electronic shelf label 90 (such as displaying and linking using the linking operation screen G11 described above, etc.) or to delete the electronic shelf label when removing it.

Next, an example of the operation of the electronic shelf label management system 1-1 will be described. FIG. 9 is an operation flow diagram of the electronic shelf label management system 1-1. As shown in the figure, the shelf label management device 50 of the electronic shelf label management system 1-1 periodically determines whether the selling price of a product (i.e., display information related to the product) has been changed (step 1-1), and if it has been changed, stores the change details in the RAM 53 or hard disk 55 as a change history (step 1-2). Next, it determines whether the product is an excluded product based on the product characteristics (step 1-3). Here, the product characteristics correspond to the above-mentioned department. For example, if the above-mentioned stationery and daily necessities are set as an excluded department, the electronic shelf label 90 will not be used for these products, and step 1-4 will be skipped. On the other hand, if the product is not in the excluded department, the process proceeds to step 1-4, where the number of changes in the change history is counted and stored. In the example of FIG. 6, the value in the selling price (number of changes) column of the corresponding product is incremented by one.

If the selling price of the product has not been changed in step 1-1, the process proceeds to step 1-12, where it is determined whether or not the required display information other than the selling price (i.e., display information related to the product), such as the place of origin or producer, has been changed, and if so, the details of the change are stored in RAM 53 or hard disk 55 as the changed required display information (step 1-13). Next, it is determined whether or not the product is an excluded product based on its product characteristics (step 1-14), and if so, step 1-15 is skipped since the electronic shelf label 90 is not used. On the other hand, if the product is not an excluded product, the process proceeds to step 1-15, where the number of changes to the required display information is counted and stored.

Next, a ranking (priority order) is generated from the total number of changes to the selling price and the required display information, in descending order of the number of changes (step 1-5). Note that, depending on the settings made in advance, the ranking may be generated from the number of changes to only the selling price change history, or the number of changes to only the required display information change history.

Next, the process proceeds to step 1-6, and it is determined whether the product is a target product of the sales plan, i.e., for example, a bargain sale product. If the product is not a target product of the sales plan, there is a possibility that the electronic shelf label 90 will be used, so steps 1-7 and 1-8 are skipped. On the other hand, if the product is a target product of the sales plan, the process proceeds to step 1-7, and it is determined whether the product is permitted to use the electronic shelf label 90, i.e., whether the electronic shelf label 90 is currently being used, and if it is permitted (used), an instruction is given to collect the electronic shelf label 90 (step 1-8). When changing the sales floor (display location) or space for a bargain sale or event, in the case of using POP advertising, even if the product uses an electronic shelf label and is not subject to switching, a collection instruction is given. The collection instruction is given, for example, by displaying the instruction on the display unit 54 of the shelf label management device 50, and at the same time displaying the contents on the display unit of the handheld terminal 85 or printing the contents by the printer 70. At this time, it is preferable to change the display of the electronic shelf label 90 shown in FIG. 10 in order to perform the switching work. For example, the lamp 99 is turned on, or the display on the display unit 94 is changed (for example, to a red display, or to a white or black display).

Next, in step 1-9, it is determined whether or not the product in question is permitted to use an electronic shelf label 90. This determination is made by giving permission to use electronic shelf labels 90 to products equal to the number of electronic shelf labels 90 available in the department, in descending order of rank (priority) determined from the total number of changes in the selling price and the number of changes in the required display information (or, as described above, the number of changes in either one). In other words, the product is determined to be eligible for the attachment of an electronic shelf label 90.

If it is determined that the product has been given permission to use the electronic shelf label 90 ("Y" in step 1-9), the process proceeds to step 1-10. If the product has already been given permission to use the electronic shelf label 90, that is, if the electronic shelf label 90 is already being used, the current situation is left as is ("Y" in step 1-10). On the other hand, if the electronic shelf label 90 is not currently being used, an instruction is given to install a new electronic shelf label 90 (step 1-11). The instruction to install is given, for example, by displaying the instruction on the display unit 54 of the shelf label management device 50, and at the same time displaying the content on the display unit of the handheld terminal 85 or printing the content by the printer 70. At this time, as in the case of step 1-8 above, it is preferable to change the display of the electronic shelf label 90 shown in FIG. 10 in order to perform the switching work.

Next, in step 1-9, if it is determined that the product is not permitted to use the electronic shelf label 90 ("N" in step 1-9), the process proceeds to step 1-16. If the product is currently permitted to use the electronic shelf label 90, that is, if the electronic shelf label 90 is currently being used, an instruction is given to collect the electronic shelf label 90 (step 1-17). The instruction to collect is given, for example, by displaying the instruction on the display unit 54 of the shelf label management device 50 and simultaneously displaying the instruction on the display unit of the handheld terminal 85 or printing the instruction by the printer 70. At this time, as in the case of step 1-8 above, it is preferable to change the display of the electronic shelf label 90 shown in FIG. 10 in order to perform the switching work. On the other hand, if the electronic shelf label 90 is not currently being used, the current situation is left unchanged ("N" in step 1-16).

The method described above makes it possible to easily and reliably generate rankings based on the number of changes to the selling price of a product or the number of changes to required display information other than the selling price of the product, and to issue instructions for installation and removal of electronic shelf labels 90 based on the generated rankings. In other words, the electronic shelf label management system 1-1 according to the present invention includes a determination means (such as a CPU 51 that executes steps 1-1 to 1-17) that determines which products are eligible for electronic shelf labels 90 according to predetermined conditions.

The electronic shelf label management system 1-1 according to the present invention also includes a counting means (e.g., the CPU 51 that executes steps 1-4 and 1-15) that counts the number of changes to the display information related to the product being sold (such as the selling price and essential display information other than the selling price), and the determination means determines the attachment target for the electronic shelf label 90 according to the number of changes to the display information related to the product counted by the counting means (e.g., the CPU 51 that executes step 1-9). As a result, the attachment target for the electronic shelf label 90 is determined according to the number of changes to the display information related to the product, so that it is possible to clearly identify the product on which the electronic shelf label 90 should be attached. For example, it is possible to easily and smoothly give priority to attaching electronic shelf labels 90 to products that have been changed many times. This makes it possible to effectively utilize the limited number of electronic shelf labels 90.

In addition, in the electronic shelf label management system 1-1, the counting means counts the number of times the selling price of the product has been changed (e.g., CPU 51 executing step 1-4), and the determining means determines the target for attaching the electronic shelf label 90 according to the count result of the number of times the selling price has been changed counted by the counting means (e.g., CPU 51 executing step 1-9). This makes it possible to accurately detect products on which electronic shelf labels 90 are to be attached.

The electronic shelf label management system 1-1 also includes a collection instruction means (such as the CPU 51 that executes step 1-17) that instructs the collection of electronic shelf labels 90 of products that have been excluded from the electronic shelf label 90 attachment targets by the determination means, so that collection of electronic shelf labels 90 that need to be collected can be instructed as appropriate. This prevents collection from being delayed or forgotten.

The electronic shelf label management system 1-1 also includes an attachment instruction means (such as the CPU 51 that executes step 1-11) that instructs the attachment of electronic shelf labels to products that have been designated as targets for electronic shelf labels 90 by the determination means, so that installation of electronic shelf labels 90 that need to be installed can be instructed appropriately. This prevents installation from being delayed or forgotten.

The electronic shelf label management system 1-1 also includes a storage means for storing products to be excluded from the judgment targets of the judgment means (such as the CPU 51 that executes steps 1-3 and 14). This makes it possible to exclude products whose selling price and required display information generally do not change from the beginning as targets for which the electronic shelf label 90 is used, thereby enabling the electronic shelf label 90 to be used more efficiently.

In addition, in the electronic shelf label management system 1-1, when the product is a product that is the subject of a sales plan, the determination means determines that the product that has been excluded from the determination means in the storage means is a product that is the subject of the collection instruction means (e.g., the CPU 51 executing steps 1-6, 7, and 8). Products that are the subject of a sales plan are displayed for a certain period of time in a corner that is different from the usual display location, for example, a corner for special sales. In such a case, it is better to use POP advertising, which is a type of product shelf label, rather than electronic shelf labels 90, because POP advertising is more effective as it is only used for a short period of time and has a high customer attraction effect. Therefore, by excluding products that are the subject of a sales plan from the products that can be used with electronic shelf labels 90, it is possible to use electronic shelf labels 90 more efficiently.

Next, another example of the operation of the electronic shelf label management system 1-1 will be described. FIG. 16 is another operation flow diagram of the electronic shelf label management system 1-1. In this embodiment, an example is shown in which the electronic shelf label 90 is switched only by changing the selling price of the product. As shown in the figure, the shelf label management device 50 of the electronic shelf label management system 1-1 periodically determines whether the selling price of the product has been changed (step 2-1), and if it has not been changed ("N" in step 2-1), it returns to step 2-1 again. On the other hand, if it has been changed ("Y" in step 2-1), it next determines in step 2-2 whether the product is an excluded product. An excluded product in this case refers to a product for which the use of the electronic shelf label 90 or product shelf label (POP advertising) is fixed, regardless of the number of times the selling price of the product has been changed.

If the product is excluded ("Y" in step 2-2), the process returns to step 2-1. On the other hand, if the product is not excluded ("N" in step 2-2), the process proceeds to step 2-3, where the number of times the product has been changed is calculated, and a ranking is generated based on the number of changes (step 2-4).

Next, based on the generated ranking, it is determined whether the product is to be excluded from the use of the electronic shelf label 90 or whether it is to be newly included in the use of the electronic shelf label 90 (step 2-5). If it is determined that the product is to be excluded from the use of the electronic shelf label 90, an instruction is given to collect the electronic shelf label 90, and an instruction is given to attach the collected electronic shelf label to a new product to be displayed (step 2-6).

Next, another example of the operation of the electronic shelf label management system 1-1 will be described. FIG. 17 is another operation flow diagram of the electronic shelf label management system 1-1. In this embodiment, an example is shown in which the electronic shelf label 90 is switched only by changing the display information other than the selling price of the product. As shown in the figure, the shelf label management device 50 of the electronic shelf label management system 1-1 periodically determines whether the display information other than the selling price of the product has been changed (step 3-1), and if it has not been changed ("N" in step 3-1), it returns to step 3-1 again. On the other hand, if it has been changed ("Y" in step 3-1), it is next determined in step 3-2 whether the product is an excluded product. Then, if it is an excluded product ("Y" in step 3-2), it returns to step 3-1, and if it is not an excluded product ("N" in step 3-2), it proceeds to step 3-3, calculates the number of changes to the product, and then generates a ranking according to the number of changes (step 3-4). Next, based on the generated ranking, it is determined whether the product is to be excluded from the use of the electronic shelf label 90, or whether it is to be newly included in the use of the electronic shelf label 90 (step 3-5). If it is determined that the product is to be excluded from the use of the electronic shelf label 90, an instruction is given to collect the electronic shelf label 90, and an instruction is given to attach the collected electronic shelf label to a new product to be displayed (step 3-6).

In each of the above operation examples, the installation or removal of the electronic shelf label 90 is instructed based on the number of changes in the selling price of the product and/or the number of changes in other display information, but the conditions for the installation or removal instruction may be set in more detail. For example, for a product in the fresh produce section, the number of changes in display information such as the place of origin may be given priority over the selling price, while for other products, the number of changes in the selling price may be given priority. As a method of giving priority, for example, the number of changes may be weighted. For example, the number of changes in the selling price may be weighted differently (number of changes x 1.0), while the number of changes in other display information may be weighted (number of changes x 0.6).

In the case of the operation flow described in Figures 16 and 17, the electronic shelf label management system 1-1 according to the present invention is configured to include a storage means for storing in advance the products (electronic shelf label fixed products) to be fitted with electronic shelf labels 90, and to exclude the products from being counted by the counting means (e.g., the CPU 51 executing steps 2-2 and 3-2). This ensures that products for which electronic shelf labels 90 are to be used are included as targets, regardless of the number of times the display information has been changed.

In addition, in the case of sales promotion, for example, even in the case of a fixed electronic shelf label (a setting that uses electronic shelf labels regardless of the number of times the display information is changed), if the sales floor (display location/space) changes, the electronic shelf label may be the target of POP advertising, i.e., product shelf labels. In other words, there are cases where a sales plan "bargain, etc." is given priority above all else. FIG. 18 is an operational flow diagram of a method for determining how to handle an electronic shelf label 90 depending on the presence or absence of a sales plan, etc. In the figure, the shelf label management device 50 of the electronic shelf label management system 1-1 determines whether or not it has received a notification that the target product has become the target of a sales plan (such as a target for an expansion of display space or a target for a change of display location) (step 4-1), and if it has not become the target, it proceeds to step 4-5 and the electronic shelf label 90 is the target for normal collection or installation. In that case, the display unit 54 of the shelf label management device 50 may display that fact. On the other hand, if it is determined in step 4-1 that the target product has become the subject of a sales plan or the like, an instruction to collect the electronic shelf label 90 is displayed, for example, on the display unit 54 (step 4-2). Furthermore, if a condition for attaching (reusing) the electronic shelf label 90 again after the sales plan or the like ends is not set ("N" in step 4-3), the electronic shelf label 90 is returned to the subject of collection or attachment as a normal electronic shelf label 90. On the other hand, if a condition for attaching (reusing) the electronic shelf label 90 again after the sales plan or the like ends is set ("Y" in step 4-3), the process proceeds to step 4-4, where the electronic shelf label 90 is stored as is and is not subject to switching to an electronic shelf label 90 for a new product. In this case, a message to that effect may be displayed on the display unit 54.

In the case of the operation flow described in FIG. 18, the electronic shelf label management system 1-1 according to the present invention is configured such that when a product becomes a target product of a sales plan, the collection instruction means instructs the collection of the electronic shelf label 90 even for products that have been previously fixed to use the electronic shelf label 90 (steps 4-1, 4-2). In this case, the collected electronic shelf label 90 may be stored so that the electronic shelf label 90 can be attached again to the product after the sales plan is completed (steps 4-3, 4-4).

As described above, electronic shelf labels are usually more expensive than product shelf labels such as paper-based POPs and price cards, so if electronic shelf labels were adopted for all products handled, the investment amount would balloon. Therefore, it is considered preferable to use product shelf labels and electronic shelf labels in parallel.
On the other hand, the products for which product shelf labels and electronic shelf labels are effective change depending on the situation, so it becomes necessary to switch between electronic shelf labels and product shelf labels.
For example, for new products, special sale items, and other sale items, POP advertising is used, and for products whose prices fluctuate infrequently, there is little need to use electronic shelf tags, which can easily accommodate frequent changes to the display of product information (such as place of origin, selling price, and sale name), so a switch to paper product shelf tags is made. On the other hand, for products whose prices fluctuate frequently, a switch to electronic shelf tags, whose prices can be easily changed, is necessary.
However, in the past, when the switching was left to the experience of store clerks, the appropriate timing for switching between electronic shelf tags and product shelf tags was off, and there was a risk of operational mistakes occurring during the switching. For this reason, there was a need to make it possible to accurately execute the timing and operation of switching between electronic shelf tags and product shelf tags based on sales plans, price changes, changes in product location, and other factors.

The above problems can be solved by adopting the electronic shelf label management system of the present invention. There are also multiple types of electronic shelf labels depending on the face. When the product display face is very narrow, such as for toothbrushes and ballpoint pens, a vertical type can be used, and when the display space for products such as fresh produce is relatively large, large electronic shelf labels similar to POP advertisements can be used. When determining which electronic shelf labels should be attached or removed, in addition to the number allocated by department or category, a condition based on the type of electronic shelf label can be added in association with product or display information. This can further improve efficiency and increase the return on investment.
