In addition, the lamp 51 is turned on when a special sale of a product on which the display modules S1 to Sn are installed or a special item is to be advertised, and the user uses the key portion 22 of the control unit 2 to light the lamp. Command to turn on (51), and according to the control operation, the CPU 25 transmits the corresponding command through the encoder 26 and the repeater 3, and receives the command transmitted through the repeater 3; The control unit 46 of the display modules S1 to Sn controls the power supply unit 50 so that power is supplied to the lamp 51 so that the lamp 51 is turned on.

FIG. 6 illustrates an embodiment of the display modules S1 to Sn applied to the present invention. An LCD 49 is formed at one side of the front surface of the case 60 formed in a rectangular shape, and the light is concentrated on the right side of the power supply unit 50. ), A light collecting plate 50a to be supplied is provided, and a key 47 is provided at the lower end of the light collecting plate 50a.

Then, a receiver 41 and a transmitter 44 for transmitting and receiving a wireless signal are respectively provided between the LCD 49 and the light collecting plate 50a, and the lamp 51 for lighting is placed on the upper end of the case 60. Connection port (Port) which can be combined is provided, the lighting lamp 51 is installed in this connection port.

The LCD 49 has a display area divided into an upper display area A and a lower display area B, and on one side of each display area A and B, an up-down direction for displaying a display position of an article. '↑' and '↓' arrows are displayed.

That is, if the display items are displayed above the display modules S1 to Sn, the '↑' arrow in the upper display area A is displayed, and if the display items are displayed below the display modules S1 to Sn, '↓' arrow in the display area B is displayed.

7A to 7C show an embodiment of a message displayed on the LCD 49 of the display modules S1 to Sn. The upper display area A shows the description of the article, the article name, and other information. And the selling price of the goods in the lower display area (B). A message displayed in the upper display area (A) is displayed from right to left of the upper display area (A) as shown in FIGS. 7A to 7C. It is displayed in order as it moves forward.

In addition, the display method of the message may be displayed such that a certain letter moves from the center of the display area A to the top, in addition to moving forward from the right side to the left side of the display area A as described above. It can also be set to appear and disappear in the center of A).

FIG. 8 illustrates a state in which display modules S1 to Sn are installed on a display rack, wherein articles are displayed between display racks formed of a plurality of layers, and display modules for transmitting a price or a message of the article to the display rack ( S1 to Sn) are provided.

The display modules S1 to Sn may be attached to a display stand or may be inserted into a separate guide rail.

The operation and effects of the present invention configured as described above will be described in detail with reference to FIGS. 4 and 5.

First, the user displays the articles on the display rack, and installs display modules S1 to Sn corresponding to each article on the display rack.

Then, the unique addresses and the corresponding product codes of the display modules S1 to Sn provided in each article are set and stored in the memory 23 of the control unit 2.

Thereafter, in order to display the price of each item and a predetermined message on the display modules S1 to Sn, the user operates the key unit 22 to input a product code, a message to be displayed, and a product price of the product. Give a transfer command.

According to the user's command, the CPU 25 supplies the input information to the encoder 26, and the encoder 26 encodes the input information and wirelessly transmits the information through the repeater 3.

At this time, the receiving unit 41 of the display modules S1 to Sn installed in the display rack receives the information transmitted from the repeater 3 and outputs the information to the decoder 42. The decoder 42 decodes the received information and controls the control unit. The control unit 46 compares the product code of the received information with its own code stored in the memory 45 and accepts the same if it is the same, and ignores the received data.

When it is determined that the codes are the same as a result of the code comparison, the controller 46 controls the LCD driver 48 to display the received information so that the upper display area A and the lower display area B of the display module 49 are displayed. At the same time, a message and a price are displayed, and at the same time, a predetermined response signal for notifying that the information has been received correctly is output to the encoder 43 to be wirelessly transmitted through the transmitter 44.

The response signal transmitted from the transmitter 44 is received by the repeater 3 and read by the decoder 27 and then supplied to the CPU 25 of the control unit 2, so that the CPU 25 responds to this response. By using the signal, it is determined whether the information transmitted by the user is correctly transmitted to the corresponding display module 49.

Repeating a series of processes as described above, it is possible to accurately and quickly set the price of the goods displayed on the shelves at a distance.

In addition, when the price of a particular item changes or executes a special sale for each time period, the changed information and price are displayed on the display modules S1 to Sn installed in the corresponding item, and the lamp 51 is turned on. Special sale products are easy to identify.

In addition, when the operator inputs the keys 47 of the display modules S1 to Sn, the controller 46 recognizes the secondary information about the display items stored in the memory 45, that is, the stock amount, the order amount, and the like. By displaying the information on the LCD 49, the operator can easily grasp the inventory of the display article and cope with it.

As described above, the present invention transmits and receives the product information and the price information as wireless information on the display module installed on the display rack, so that each display module installed on the display rack is wirelessly installed, the installation cost is significantly reduced, and the price of the article is increased. Not only can the display be quickly and accurately, but also the price of the item can be changed quickly in response to the price of the particular item that changes instantaneously, and a particular key is installed on the display means installed on the display stand, so that the operator can select the key. It is a two-way wireless electronic information display device that allows you to grasp information such as inventory quantity, order quantity, purchase price, and promotional price of the display goods.
