Description

Description: (a) Technical Field The present invention relates to a price display system for transmitting and receiving data such as product prices between an electronic cash register (hereinafter referred to as ECR) according to the present invention and a display device installed on a product shelf.

(B) Background of the Invention Currently, the ECR has a PLU file that stores the price of a product, and an employee such as a store clerk refers to the data to register the sales. On the other hand, a customer who purchases a product determines the price of the product by looking at the price displayed on the product shelf (hereinafter referred to as the display price).

Therefore, when the price of the product is changed, it is necessary to double the maintenance of the price data of the PLU file and the replacement of the display price, and if there is a time lag between these operations, it will be registered. The price and the price judged by the customer were different, which sometimes caused trouble.

In addition, when the customer points out that the registered price and the displayed price are different at the time of registration, or when the inquiry about the price of the product is received, the staff member has to go to the product shelf to see the price. It wasted time and was a cause of unnecessary waiting time for other customers.

(C) Object of the Invention In view of the above drawbacks, the present invention is a price display system capable of simultaneously changing the display of a product shelf at the time of maintenance of a PLU file and displaying the display price of an arbitrary product shelf on an ECR display if necessary. The purpose is to provide.

(D) Configuration of the Invention The present invention comprises an electronic cash register having a PLU file for storing the name, price, etc. of a product, and a price display device installed on a product shelf for displaying the product price, the electronic cash A register transmits at least product price data to the price display device, and the price display device is a price display system that receives and displays the product price data transmitted by the electronic cash register, wherein the electronic cash register A price display device that displays the product price data of the product corresponding to the desired PLU code, and includes price data requesting means for requesting the transmission of the product price data. The price at which the commodity price data is transmitted to the electronic cash register in response to the price data transmission request from the requesting means. Further, the electronic cash register is provided with data transmitting means, and the electronic cash register displays the price data receiving means for receiving the commodity price data transmitted from the price data transmitting means, and the commodity price data received by the receiving means. It is characterized by comprising price data display means.

(E) Embodiment FIG. 2 is a schematic configuration diagram of a price display system by ECR which is an embodiment of the present invention. A plurality of price display devices 2 are connected to the ECR 1. The price display device 2 has a CPU, a memory, a display device, a transmission device for communicating with the ECR, and the like, and is installed on each product shelf for displaying the product for displaying the price.

FIG. 3 is a block diagram of the ECR. The CPU 11 includes a ROM 12 for storing programs, a RAM 13 including a PLU file, a display device 14 for displaying prices, a printer 15 for printing receipts at the time of registration, a keyboard 16, a cash box control unit for controlling opening / closing of a cash box. A transmission device 18 for transmitting and receiving data and the like is connected to the price display device 17 and the price display device.

FIG. 4 is a layout diagram of the keyboard 16. A key switch 60 can be switched to any one of a program mode, a registration mode, an inspection mode, and a settlement mode. Reference numeral 61 is a department key, and in this embodiment, five keys are assigned corresponding to the product department. The numeral 62 is a ten-key pad for inputting the amount and PLU code. 63 is a function key. Of these, 63a is a multiplication key. 63b is PL
The U key, 63c is a subtotal key, and 63d is a cash sales key.

FIG. 5 (A) is a diagram showing a key sequence when the price is set in the ECR. After setting the key switch to program mode, first enter the price, press the multiplication key, enter the PLU code of the product and press the PLU key,
ECR performs the pricing operation.

FIG. 5 (B) is a key sequence when the ECR calls the price display device installed on the product shelf and displays the displayed price on the ECR display (shelf price display). After setting the key switch to registration mode, press the multiplication key,
If you enter the PLU code and press the PUL key, the ECR will display the product price.

Hereinafter, the operation of the ECR will be described with reference to the flowchart.

FIG. 1 (A) is a flowchart for setting a price. The fifth step n1 (hereinafter, step ni is simply called ni)
When the key operation shown in FIG. 6A is performed, the price input in the PLU file is set (n2), and data to be transmitted to the price display device is created from this data (n3). FIG. 6 shows a block diagram of the data to be transmitted. In addition to the product price, this data also includes the product name and price update time. In n4, the data created in n3 is transmitted to the price display device, and if it is confirmed in n5 that the data has been transmitted to the price display device, the contents input in n1 are printed on the printer 15 and the operation is stopped. n5 is a step for causing n4 to execute the transmission again when the transmission is not OK. n3 and n4 correspond to the price transmission means of the present invention. FIG. 7 shows a display example of the price display device.

FIG. 1B is a flow chart when the shelf price is displayed.
When the key operation shown in FIG. 5 (B) is performed at n8, a transmission request for the displayed contents is output to the price display device displaying the price of the product corresponding to the PLU code input at n8 ( n9), the ECR enters the receiving operation (n10). If it is determined that the reception is completed in n11, the process proceeds to n12, and if not completed, n9, n10
Repeat the operation of. At n12, the received data is edited in a format that can be displayed on the ECR display, displayed (n13), and stopped. n9 to n13 correspond to the price display means of the present invention.

If the price display system with the above configuration is used in stores, etc.,
The price displayed on the price display device on the product shelf is updated at the same time when the R PLU file is maintained, which saves you the trouble of changing the display price on the product shelf, and the registered price by the PLU file on the ECR and the display price on the product shelf. It is possible to prevent troubles caused by different from. Further, since the price displayed on the product shelf can be displayed on the ECR display, it is possible to save the trouble of going to the product shelf when the customer inquires about the product price.

(F) Effects of the Invention As described above, according to the present invention, the ECR is transmitted to the price display device installed on the product shelf and the displayed commodity price output data is transmitted from the price display device to the ECR. ECR (cash register)
In the case of trouble caused by the difference between the registered price and the display price on the product shelf or when the customer inquires about the price, the display price can be immediately displayed on the ECR, so the cashier can display the price on the product shelf. It is possible to eliminate the trouble of seeing and to facilitate the cash register work.
