Is set.

First, the management apparatus 101 determines whether or not various data such as a product name and a discount price have been input from itself (step 601 in FIG. 6). It is determined whether or not data has been input (step 602). If data has not been input from the POS main unit 123, it is determined whether or not the set time has come (step 603). This set time is the time set in the time, set price and stock quantity correspondence table in FIG. If the set time has not come, the process returns to step 601 without performing the process.

On the other hand, when data is input from the POS main unit 123 in step 602, the management device 101 stores the same data as the above-mentioned data in the storage device 124.
Is updated (step 607). Next, if the price card data is not updated, the process is terminated, and if it is updated, the price card data updating process is performed (steps 608 and 609). When the data is price data, the price data used at the cash registers 125 to 127 and the price cards 107 to 112 corresponding to the price data,
The displays 117 to 122 are changed at the same time.

If it is determined in step 603 that the set time has come, it is determined whether or not the set stock quantity set in the time, set price and stock quantity correspondence table of FIG. 5 is larger than the current product stock quantity. (Step 604). At this time, if the current stock quantity is smaller than the set stock quantity, the process is terminated and the process returns to step 601. If it is larger than the set stock quantity, the price display section 203 of the price card for today is displayed.
The product data is transmitted to the price card in order to update the discount price displayed in (1) to the set price in FIG. 5 (step 605).

At the same time, set price update data is also transmitted to the POS device 123 in order to match the price data of the POS main unit 123 (step 606). Step 6
When the price data of the price card is displayed and updated in 05, the management apparatus 101 transmits the device number code to the repeaters 103 and 113 via the transceiver 102 together with the product data. If the device number code corresponds to the repeater 103, the repeater 103 discriminates this and performs the reception processing of the product data. At this time, since the repeater 104 is different from its own device number code, the repeater 104 does not perform the process of receiving the product data.

The repeater 103 transmits the received product data to the price cards 107 to 112 under its jurisdiction.
Each of price cards 107 to 112 determines that there has been a data update request from management device 101 (step 801 in FIG. 8), and determines whether the ID code included in the product data matches its own ID code. (Step 80
2). For a price card that does not match its own ID code, the subsequent processing is not performed.

For a price card that matches its own ID code, it is determined whether or not to update the price data (step 803). If the price data is related to a normal price, the display price on the normal price display unit 202 is updated. Processing (step 807), and if it is related to today's price, the display price of today's price display unit 203 is updated (step 8).
08).

If the price data is not updated in step 803, it is determined whether to update the data of the remaining number of commodities (step 804). If it is determined that the price card is to be updated, if the price card has a remaining number display area, the display of the remaining number is updated (step 80).
6) If there is no remaining number display area, the process ends without updating the display. Also, in step 804, when the remaining number data is not updated, the process is terminated without performing the process, and the process returns to step 801.

On the other hand, if there is data input at step 601 in FIG. 6, if there is an input of the product name or the ID code of the product, the display is switched to the display screen of the product. As a result, the display of FIG. 5 is performed, and the process returns to step 601 (steps 701 and 709). If the merchandise name or the ID code of the merchandise is not inputted, the process proceeds to step 702, and it is determined whether or not each data of the correspondence table of the time, the set price and the stock quantity in FIG. Is input, the input data is updated (step 71).
2).

In step 702, when the weather information of the current day is input without inputting the setting of the time, the set price and the stock quantity (step 703), the weather data is updated (step 707), and the weather data and the predetermined value or more are set. The past data having the similarity of the above is switched and displayed (step 708). When inputting the past detailed data without inputting the weather data in step 703, by clicking the past “year / month / day” displayed in FIG. 5 with an input device such as a mouse,
A screen display of past data corresponding to FIG. 5 is performed (step 711).

In step 704, when the past detailed data is not entered but registered, the data is stored in the storage device 124 and transmitted to the price card and the POS main unit 123 (step 706). As a result, the price displayed on the price card matches the price data used at the cash registers 125 to 127. When the registration input is not performed, the screen is switched to the data input screen and the process returns to step 601 (step 710).

FIG. 9 is a front view showing a second embodiment of the electronic price card. In the present embodiment, it is configured to enable price display in weight units. That is, a weight display section 901 for displaying a normal unit weight, a weight display section 903 for displaying a today's unit weight, a normal price display section 902 for displaying a normal price per unit weight, and a unit weight.
