  FIG. 8 is a flowchart showing an information processing procedure of inventory work executed by the CPU 35 of the handy terminal 3. This procedure is in accordance with a control program stored in the ROM 36. That is, when the handy terminal 3 is started up by turning on the power and the control program is activated, the CPU 35 causes the display 33 to display a menu screen (Act 1). On the menu screen, a menu of tasks that can be executed on the handy terminal 3 is displayed so as to be selectable. This work menu includes an inventory work.

  A person in charge of performing inventory work (hereinafter referred to as a person in charge of inventory) carries the handy terminal 3 and goes to the sales floor. Then, the inventory operation is selected from the menu screen.

  The CPU 35 waits for a job to be selected (Act 2). When any operation in the operation menu is selected by the operation input of the shift key and the enter key (YES in Act 2), the CPU 35 determines the operation (Act 3).

  When an inventory operation is selected (YES in Act 3), the CPU 35 displays a shelf category selection screen on the display 33 (Act 4). On the shelf category selection screen, a shelf category for specifying each product shelf is displayed so as to be selectable. An image of a button declaring the end of business (hereinafter referred to as a business end button) is also displayed.

  The person in charge of inventory selects the shelf classification of the product shelf to be inventoried from the shelf classification selection screen. That is, each product displayed on the product shelf specified by the selected shelf category is an inventory target. When the inventory work is to be ended, a job end button is input.

  The CPU 35 waits for a shelf category to be selected from the shelf category selection screen (Act 5). Further, the CPU 35 confirms whether or not a business end button has been input (Act 6). If any shelf category is selected by the operation input of the shift key and the enter key (YES in Act 5), the CPU 35 sends an inventory command including the shelf category to the shelf label server 23 via the wireless unit 38. (Act7). Then, the CPU 35 waits for a response signal from the shelf label server 23 (Act 8). The response signal includes an affirmative response signal for accepting the inventory work and a negative acknowledge signal for not accepting the stocktaking operation.

  When an acknowledgment signal is received via the wireless unit 38 (YES in Act 8), the CPU 35 causes the display 33 to display an inventory screen (Act 9). On the inventory screen, guidance for prompting input of a product code and a stock number of an inventory target product is displayed. In addition, an image of a button for declaring the end of the inventory work for the product shelf specified by the selected shelf category (hereinafter referred to as an inventory end button) is also displayed.

  The person in charge of inventory inputs a product code and a stock number for each product to be inventoried. The product code is input by scanning the barcode with the scanner 34, for example. The number of stock points is input by operating the numeric keypad and enter key of the keyboard 32. When the inventory data for all the products to be invented has been input, the person in charge of the inventory inputs an inventory end button.

  The CPU 35 waits for inventory data to be input (Act 10). Further, the CPU 35 confirms whether or not an inventory end button has been input (Act 11). When the inventory data including the product code and the inventory score is input (YES in Act 10), the CPU 35 transmits the inventory data to the shelf label server 23 via the wireless unit 38 (Act 12). Thereafter, the CPU 35 waits for the next inventory data to be input (Act 10).

  On the other hand, when the inventory end button is input (YES in Act 11), the CPU 35 transmits an end command to the shelf label server 23 via the wireless unit 38 (Act 13). Then, the CPU 35 waits for a response signal from the shelf label server 23 (Act 14). The response signals include an affirmative response signal for affirming the end of inventory and a negative response signal for negating the end of inventory.

  When a negative response signal is received via the wireless unit 38 (NO in Act 14), the CPU 35 displays a message warning that the inventory work is not completed on the display device 33 (Act 15). Thereafter, the CPU 35 returns to the processing of Act10. That is, the CPU 35 waits for input of inventory data or input of an inventory end button.

  On the other hand, when an affirmative response signal is received (YES in Act 14), the CPU 35 returns to the process of Act 4. That is, the CPU 35 causes the display 33 to display a shelf category selection screen. Here, when another shelf classification is selected, the CPU 35 executes the processes of Act7 to Act15 again. Thereby, the inventory work for another product shelf is executed.

  On the other hand, when the business end button is input (YES in Act 6), the control program stops. As a result, the CPU 35 ends the information processing of the procedure shown in FIG.

  FIG. 9 is a flowchart showing a main information processing procedure executed by the CPU 231 of the shelf label server 23. This procedure is in accordance with a display control program stored in the ROM 232. When the display control program is activated, the CPU 231 sequentially fetches each shelf label data record 26R from the shelf label database 26 (Act 21). Then, the CPU 231 generates first shelf label data including a shelf label ID, a product name, and a price from each shelf label data record 26R, and each first shelf label data is specified by the shelf classification of the shelf label data record 26R. To the product shelf repeater 22 (Act 22).

  The first shelf label data distributed to each relay device 22 is distributed to the electronic shelf label 21 identified by the shelf label ID by the operation of the relay device 22. In the electronic shelf label 21 that has received the first shelf label data, the product name and price of the first shelf label data are displayed as shown in the pattern P1 of FIG. Here, the processing of Act 21 and Act 22 constitutes control means for displaying information on the corresponding products on a plurality of display devices (electronic shelf labels 21) provided for each product displayed on the sales floor.

  After transmitting the shelf label data, the CPU 231 waits for an external command (Act 23). When the command is received (YES in Act 23), the CPU 231 analyzes the command (Act 24, 25). When it is an update completion command of the shelf label database 26 transmitted from the POS server (YES in Act 24), the CPU 231 returns to the processing of Act 21.

  The shelf label data record 26R of the shelf label database 26 is updated by the POS server. When the POS server finishes updating the shelf label data record 26R, it transmits an update completion command to the shelf label server 23. Therefore, every time the shelf label data record 26R of the shelf label database 26 is updated, the CPU 231 of the shelf label server 23 generates the first shelf label data with the updated shelf label data record 26R. Data is transmitted to the corresponding repeater 22, and the updated product name and price are displayed on the electronic shelf label 21.

  When the received command is the inventory command (YES in Act 25), that is, when any shelf category is selected at the handy terminal 3 where the inventory operation is declared, the CPU 231 specifically shows the procedure shown in FIG. Execute the stocktaking process.

  First, the CPU 231 determines whether or not the inventory work can be executed (Act 31). For example, the shelf label server 23 is set with a time zone in which the inventory work can be executed, and the CPU 231 determines whether or not the current time measured by the clock unit 236 is the executable time zone.

  When the current time is not a time zone in which the inventory operation can be performed (NO in Act 31), the CPU 231 transmits a negative response signal to the handy terminal 3 that is the inventory command transmission source (Act 32). This negative response signal is sent to the radio base station 4 via the LAN 25, transmitted as a radio signal, and received by the radio unit 38 of the handy terminal 3. In this case, the inventory screen is not displayed on the display device 33 of the handy terminal 3. Therefore, the person in charge of inventory cannot execute the inventory work.

  On the other hand, when the current time is a time zone in which the inventory work can be performed (YES in Act 31), the CPU 231 searches the shelf label database 26 with the shelf classification included in the inventory command. Then, the CPU 231 reads the shelf label data record 28R including the same shelf classification and stores it in a predetermined area of the RAM 233 (hereinafter referred to as a shelf label data area) (Act 33).

  Next, the CPU 231 generates second shelf label data including a shelf label ID and barcode data from each shelf label data record 28R stored in the shelf label data area. Then, the CPU 231 transmits each second shelf label data to the product shelf repeater 22 specified by the shelf classification included in the inventory command (Act 34).

  Each second shelf label data distributed to each relay device 22 is distributed to the electronic shelf label 21 identified by the shelf label ID by the operation of the relay device 22. In the electronic shelf label 21 that has received the second shelf label data, a barcode generated from the barcode data is displayed as shown in a pattern P2 in FIG. Here, the processes of Act33 and Act34 constitute code display means for displaying a product code (bar code) for identifying the product on the display device (electronic shelf label 21) on which the information of the product to be inventoried is displayed. .

  The CPU 231 that has transmitted the second shelf label data sets all the inventory flags F1 of each shelf label data record 28R stored in the shelf label data area to “1” (Act 35). Further, the CPU 231 transmits an acknowledgment signal to the handy terminal 3 that is the inventory command transmission source (Act 36). This acknowledgment signal is sent to the radio base station 4 via the LAN 25, transmitted as a radio signal, and received by the radio unit 38 of the handy terminal 3.

  As a result, the inventory screen is displayed on the display 33 of the handy terminal 3. Therefore, the person in charge of inventory can execute the inventory work using the handy terminal 3. At this time, as described above, the bar code of the product is displayed on each electronic shelf label 21 corresponding to the product to be inventoried. Therefore, the person in charge of inventory can easily input the product code of the product to be inventoried by scanning this barcode with the scanner 34 of the handy terminal 3.

  The CPU 231 receives inventory data from the handy terminal 3 (Act 37: inventory accepting means) or waits for an end command (Act 38: end accepting means). When the inventory data has been received (YES in Act 37), the CPU 231 searches the shelf label data area and selects the shelf label data record 28R including the product code in the inventory data (Act 39: selection means). Then, the CPU 231 determines whether or not the inventory flag F1 of the shelf label data record 28R is set to “1” (Act 40).

  If the inventory flag F1 is not set to “1”, the inventory of the product specified by the product code included in the shelf label data record 28R has already been completed. In this case (NO in Act 40), the CPU 231 receives the next inventory data (Act 37) or waits for an end command (Act 38).

  When the inventory flag F1 is set to “1”, the CPU 231 transfers this inventory data to the POS server (Act 41). The POS server searches the inventory database 11 with the product code included in the inventory data, and rewrites the inventory score of the inventory data record including the product code with the inventory score included in the inventory data.

  Further, the CPU 231 transmits the third shelf label data to the product shelf repeater 22 specified by the shelf classification included in the shelf label data record 28R (Act42), and the third shelf label data is stored in the shelf label data record. It includes a shelf label ID and a product name included in 28R, and preset “inventory completed” text data. The third shelf label data is transmitted to the electronic shelf label 21 specified by the inventory ID via the repeater 22. In the electronic shelf label 21 that has received the third shelf label data, as shown in the pattern P3 in FIG. 11, the product name included in the third shelf label data and the text data of “inventory completed” are displayed. Here, the processing of Act 42 constitutes an inventory display means for causing the display device (electronic shelf label 21) selected by the selection means to display the inventory completion.

  The CPU 231 that has transmitted the third shelf label data resets the inventory flag F1 included in the shelf label data record 28R to “0” (Act 43). Thereafter, the CPU 231 returns to the process of Act37. That is, the CPU 231 receives the next inventory data (Act 37) or waits for an end command (Act 38).

  When the end command is received (YES in Act 38), the CPU 231 checks whether or not the inventory flags F1 of each shelf label data record 28R in the shelf label data area are all reset to “0” (Act 44: Confirmation) means). When the inventory flag F1 of at least one shelf label data record 28R is set to “1”, the inventory operation for the product to be inspected is not completed. In this case (NO in Act 44), the CPU 231 transmits a negative response signal to the handy terminal 3 that is the end command transmission source (Act 45).

  In the handy terminal 3 that has received this negative response signal, a message warning that the inventory work has not been completed is displayed on the display 33. Therefore, the person in charge of inventory can easily know that there are products for which inventory work has not been completed among the product shelves on which the products to be inventoried are displayed. In this case, if the person in charge of inventory confirms each electronic shelf label 21 provided on the product shelf and finds an electronic shelf label 21 on which the text data of “inventory completed” is not displayed, the electronic shelf label will be displayed. The inventory of the product corresponding to the tag 21 is performed.

If all of the inventory flags F1 have been reset to “0” (YES in Act 44), the CPU 231 makes “inventory completed” for the repeater 22 specified by the shelf classification of each shelf label data record 28R. A command for instructing the deletion of data is transmitted (Act 46). This command is distributed to all the electronic shelf labels 21 connected to the repeater 22. As a result, the display content of each electronic shelf label 21 returns from the pattern P3 state of FIG. 11 to the pattern P1 state. Here, the process of the Act46, in response to the completion of the inventory work is confirmed, forming an erase means Ru is erased an indication of inventory already display device (electronic shelf label 21).

  Thereafter, the CPU 231 transmits an affirmative response signal to the handy terminal 3 as the end command transmission source (Act 47). In the handy terminal 3 that has received this acknowledgment signal, a shelf category selection screen is displayed on the display.

  In this way, the person in charge of the inventory displays the display contents of any of the electronic shelf labels 21 provided on the commodity shelf on which the commodity to be inspected is displayed, that is, the state before starting work, that is, the commodity name and price. If it is confirmed that the state has been restored, it can be recognized that the inventory work for the product shelf has been completed. Then, when performing inventory of another product shelf, the person in charge of inventory selects a shelf category that identifies the product shelf. Then, since the inventory command is transmitted from the handy terminal 3 to the shelf label server 23, the shelf label server 223 executes the process of the procedure shown in the flowchart of FIG.

  As a result, the display content of each electronic shelf label 21 provided on the product shelf first changes from the state of the pattern P1 to the state of the pattern P2. Next, the display content of the electronic shelf label corresponding to the product for which the inventory work has been completed changes from the pattern P2 to the pattern P3. When the inventory work is completed, the display contents of the respective electronic shelf labels 21 are simultaneously returned from the pattern P3 to the pattern P1.

  Therefore, the customer service representative can confirm from the display contents of any one of the electronic shelf labels 21 whether or not there is a product that has not been inventoried, so that it can be instantly determined. Moreover, since it can confirm also from the content displayed on the indicator 33 of the handy terminal 3, it is efficient.

  Further, the customer service representative can input the product code of the product to be inspected from the barcode displayed on the electronic shelf label 21, so that workability is good.

The present invention is not limited to the above embodiment.
For example, in the above-described embodiment, the case where the text data of “inventory completed” is displayed as the display indicating the inventory completion, but the inventory display means is not limited to this. For example, the inventory completion may be displayed by turning on or blinking an LED provided on the electronic shelf label 21.

  In the above embodiment, the handy terminal 3 is exemplified as the input device for inputting the product code and the inventory score of the product to be inventoried. However, the handy terminal 3 is not necessarily required. For example, a mobile phone or a smartphone equipped with a camera can be used.

  Moreover, in the said embodiment, although the barcode of the said goods was displayed on the electronic shelf label 21 corresponding to the goods of inventory object, the process step which displays this barcode may be abbreviate | omitted. That is, even if the processing procedure is changed from the pattern P1 of FIG. 11 to the pattern P3 when the inventory of one product is completed and returns to the pattern P1 when the inventory of all the products is completed, it is easy to check whether there is an unfinished product. The effect that it can be confirmed can be produced.

  Note that the display control device is generally transferred in a state where a program such as a display control program is stored in the ROM 232. However, the present invention is not limited to this, and a display control program or the like assigned separately from the computer apparatus may be written in a writable storage device included in the computer apparatus in response to an operation by a user or the like. The transfer of the display control program or the like can be performed by recording on a removable recording medium or by communication via a network. The recording medium may be in any form as long as it can store a program such as a CD-ROM or a memory card and can be read by the apparatus. Further, the function obtained by installing or downloading the program may be realized in cooperation with an OS (operating system) in the apparatus.

  In addition, although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
