The operation of the thus constructed device will be described below. FIG. 10 is a flowchart explaining the operation of the electronic scale device. This process starts when the customer informs the store clerk about the product and quantity he / she desires to purchase.
The customer's desired purchase amount is specified by weight or price,
For example, "Maesawa beef loin steak""200g" is announced.

Then, in step SP1, the clerk inputs the product number of the product desired by the customer to the operation unit 164 of the electronic scale 10.
Enter more. There are a first input method using a numeric keypad and a product number key and a second input method using a preset key as an input method of the product number. In the first input method, as shown in the product file of FIG. 5, the product number “0005” of “Maesawa beef loin steak” is input by pressing the ten keys “5” and the product number key. In the second input method, as shown in the preset key file of FIG. 6, the preset key with the key number “02” is pressed to input the product number “0005”.

A touch panel of the operation unit 164 is assigned to the ten keys, the product number key and the preset key, and the product name of the associated product number is displayed on the key top of the preset key. Therefore, the product number can be easily input even by a salesclerk who is not skilled in operation. Taking the preset key file of FIG. 6 as an example, “Maesawa beef loin steak” is displayed on the key top of the second preset key.

When the store clerk operates the second preset key, the product number "0005" is called from the preset key file 124, and the product data of the product number "0005" is read from the product file 122 and read. The product data is displayed on the customer display 14 and the store clerk display 16. Then, the entered product number is L from the electronic scale 10.
It is transmitted to the electronic shelf label controller 34 via the AN 20. The electronic shelf label controller 34 searches the product number-shelf tag ID correspondence table 35 by this input product number, searches for the shelf label ID “2028” corresponding to the input product number “0005”, and finds the found shelf label ID “2028”. The transmitting unit 36 transmits an LED lighting command to the electronic shelf label 32 that it has. As a result, the LED 331 of the electronic shelf label 32 having the designated shelf label ID “2028” is turned on, so that the LED 331 of the electronic shelf label 32 of the product “Maesawa beef loin steak” that the customer desires to purchase is turned on. As a result, the customer can confirm whether the product handled by the store clerk matches the ordered product.

Next, in step SP2, the store clerk puts the product desired by the customer on the weighing pan 12. Then, the electronic scale 10
Measures the weight of the product placed on the weighing pan 12, and displays the measured weight on the customer display 14 and the store clerk display 16 (step SP3). The electronic scale 10 calculates the price from the measured weight and the called unit price and displays it on the customer display 14 and the store clerk 16 (step SP4). The store clerk compares the displayed weight or price with the weight or price ordered by the customer, and if they do not match, adds or removes the item and adjusts it to match (step SP5).

Next, in step SP6, the store clerk receives the payment from the customer and inputs the deposit amount into the cash register function unit of the electronic scale 10. Then, the price is subtracted from the price, and the change is calculated and displayed. Then, the receipt is printed and issued, and the merchandise, the receipt, and the change are delivered to the customer (step SP7). Then, when the product is removed from the weighing pan 12 and the weight becomes “0”, the electronic scale 10 resets the display and ends the processing for the customer this time.

When the receipt is printed and issued, the information that the product has been delivered to the customer is transmitted to the electronic shelf label controller 34 via the LAN 20. Upon receiving this information, the electronic shelf label controller 34 sends a turn-off command to the electronic shelf label 32 having the shelf label ID for which the LED 331 is lit. As a result, "maezawa beef loin steak"
The LED 331 of the electronic shelf label 32 is turned off.

FIG. 11 is a block diagram for explaining the second embodiment of the present invention. In the present embodiment, two electronic shelf labels, one on the customer side and one on the store clerk side, are set for each product. In this case, assuming that the shelf label ID is the same for the customer side electronic shelf label 32b and the clerk side electronic shelf label 32a for each item, the electronic shelf label controller 34 has a single shelf label ID for the customer side electronic shelf label 32b. And the clerk-side electronic shelf label 32a can be operated at the same time.
As another embodiment, the shelf label IDs for the customer-side electronic shelf label 32b and the clerk-side electronic shelf label 32a may be different between the two. In this case, the electronic shelf label controller 3
4 transmits the shelf label IDs for the customer-side electronic shelf label 32b and the clerk-side electronic shelf label 32a, respectively. In another embodiment, the customer-side electronic shelf label 32b is the electronic shelf label 32 shown in FIG.
The clerk-side electronic shelf label 32a may be composed only of LEDs that are interlocked with the LEDs 331 of the customer-side electronic shelf label 32b.

With this configuration, the electronic shelf label 3 for the clerk
Since the store clerk only needs to take out the product according to the lighting of the LED of 2a, the possibility that the store clerk takes out the wrong product is reduced. That is, as a mistake to receive a product different from the product ordered by the customer,
There is a case where the store clerk mistakenly recognizes the customer's ordered product, and a case where the store clerk mistakenly recognizes the customer's ordered product but mistakenly takes out the product when taking out the product from the showcase.
By providing the store clerk-side electronic shelf label 32a, it is possible to prevent the error from occurring not only.

In the above embodiment, the case of one-way communication from the electronic shelf label controller to the electronic shelf label has been shown, but the present invention is not limited to this, and the electronic shelf label controller and the electronic shelf label are combined. It may be configured to perform bidirectional communication between the two. Here, the communication between the electronic shelf label controller and the electronic shelf label is not limited to infrared rays, but electric wires may be used, or ultrasonic waves or electromagnetic waves may be used. Further, the case where the electronic scale device is constructed by the electronic shelf label and the electronic shelf label controller for the existing electronic scale is shown, but the present invention is not limited to this, and as shown in FIG. The electronic scale with the built-in shelf label controller function may be configured to control the lighting of the electronic shelf label.

Furthermore, in the above embodiment, the electronic shelf label is used to display the customer-ordered product so that the customer can recognize it. However, if the product of the product number input to the electronic scale can be confirmed, the LED is simply arranged. But good. Also, the electronic shelf label L
The price display may be turned on without being limited to the case where the ED is turned on. In short, it is only necessary that the customer can confirm the product with the product number input to the electronic scale.
