DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 1 shows a system (price tag system) for transmitting and receiving data between an ECR 11 and an electronic price tag apparatus 12 using an optical signal (infrared ray) as a transmission medium. ECR11
Denotes a CPU 11-1 and an input unit 11-
2, display unit 11-3, PLU memory 11-4, printing unit 1
The CPU 11-1 performs a registration process of sales data according to a microprogram stored in advance. That is, the CPU 11-1 receives the PLU code input from the input unit 11-2 or the PLU code transmitted from the electronic price tag device 12 by the receiver 11-6 based on the PLU code input. PLU
The memory 11-4 is searched, and the price is added to the total sales of the corresponding PLU code. In this case, the CPU 11-1
Sends the sales data to the display unit 11-3 for display,
Printing is performed on the receipt and journal set in the printing unit 11-5.

The PLU memory 11-4 controls data writing and reading operations under the control of the CPU 11-1. The PLU memory 11-4 stores the product name, price, and total sales in accordance with the PLU number (PLU code). It has a configuration.
Here, the PLU number, the product name, and the price in the PLU memory 11-4 are setting data input and set in advance from the input unit 11-2, and the data set in the PLU memory 11-4 is the transmitter 11-7. And sent to each electronic price tag device 12 by an optical signal.

[0008] The receiver 11-6 and the transmitter 11-7 are arranged on the back side (customer side) of the ECR main body.

The electronic price tag device 12 has a CPU 12-1 as a core, a receiver 12-2, a display unit 12-3, a memory 12
-4, and a transmitter 12-5. CP
U12-1 executes data transmission / reception processing, display processing, and the like according to a microprogram stored in advance. That is, when the setting data transmitted from the ECR 11 is received by the receiver 12-2, the CPU 12-1 sends the setting data to the memory 12-4 to store the setting data, and includes a “product name” included in the setting data, Display "Price" 12
-3 for display.

The CPU 12-1 reads the PLU code set in the memory 12-4 and reads the PLU code from the transmitter 12-.
5 and a PLU code is transmitted from the transmitter 12-5 by an optical signal.

FIG. 2 is an external view of the electronic price tag device 12. The case body of the electronic price tag device 12 has a horizontally long box shape as a whole, and a liquid crystal constituting a display section 12-3 is provided on the front surface thereof. A display panel 12-6 is provided, and a receiver 12-2 and a transmitter 12-5 are provided. The electronic price tag device 12 configured as described above is incorporated in the center of the hanger.

Next, the operation of this embodiment will be described with reference to FIGS. 3 is a flowchart showing the operation of the ECR 11, FIG. 4 is a flowchart showing the operation of the electronic price tag device 12, and FIG.
The transmission format of data transmitted and received between the CR 11 and the electronic price tag device 12 is shown.

First, when setting a price or the like in the PLU memory 11-4 on the ECR 11 side, a mode change switch (not shown) provided in the input unit 11-2 is set to a setting mode. . In this setting mode (step A1), when PLU data (PLU code, product name, price) is input from the input unit 11-2 according to a normal key operation procedure, the input PLU data becomes P
The data is written to the LU memory 11-4. Thus P
When the settings for the LU memory 11-4 are made, step A
Then, the process proceeds to step 3 to check whether a setting command for instructing that the data set in the PLU memory 11-4 should be transmitted to the electronic price tag device 12 has been input. This setting command is input unit 1
This is input by operating a specific key (not shown) provided in 1-2. If no setting command is input, the process directly returns to step A1, but if a setting command is input, Proceed to step A4 and
After transmitting the data set in the U memory 11-4 from the transmitter 11-7 by an optical signal, the process returns to step A1. Therefore, after writing all the PLU data to be set in the PLU memory 11-4, the contents of the PLU memory 11-4 may be transmitted to the electronic price tag device 12 in a lump.
The LU data may be transmitted while being written to the PLU memory 11-4 one by one.
All data set in the LU memory 11-4 is transmitted to the electronic price tag device 12.

In this case, the setting data transmitted from the ECR 11 to the electronic price tag device 12 has a data structure as shown in FIG. 5, and includes a setting command, a PLU code (PLU code before change), a changed PLU code ( PLU code after change), product name, and price data.

When such setting data is transmitted from the ECR 11 to the electronic price tag device 12, the electronic price tag device 12
Works as follows. That is, the electronic price tag device 12 shown in FIG.
As shown in (1), when the data transmitted from the ECR 11 is received (step B1), it is checked whether or not the received data includes a transmission command described later (step B2). Since the transmission command is not included, the process proceeds to step B3, and it is checked whether the reception data includes the setting command. In this case, since the setting command is included, the process proceeds to step B4 to compare the PLU code (the PLU code before change) included in the setting data with the PLU code preset in the memory 12-4. It is checked whether they match, that is, whether the data is transmitted to itself. Here, if a mismatch is detected between the two, the process returns to step B1 to cancel the received data. If the setting data is transmitted to itself, the setting data is sent to the PLU memory 11-4, and the contents are sent to the PLU memory 11-4. In addition to rewriting, the “product name” and “price” in the setting data are extracted, and the display unit 1
After displaying in 2-3, the process returns to step B1.

As described above, when the PLU data is changed on the ECR 11 side, the changed data is transmitted to the electronic price tag device 12.
And the display contents of the display unit 12-3 are changed.

If neither the transmission command nor the setting command is included in the received data, the process proceeds to step B6, where other processing is performed.

Next, the customer purchases a product (clothes), carries the product together with the hanger to the set position of the ECR 11, and performs accounting.

In this case, the ECR 11 operates a registration key RK provided in the input unit 11-2 in the registration mode. Then, this is detected in step A5 and the process proceeds to step A6, where a transmission command for requesting the electronic price tag device 12 to transmit registration data is transmitted and received 11-7.
Send from.

When such a transmission command is sent to the electronic price tag device 12 and received by the receiver 12-2 of the electronic price tag device 12 (steps B1 and B2), registration data is created and transmitted. Send from -5. The registration data in this case includes a registration command and a memory 1 as shown in FIG.
And PLU code read from 2-4.

When the registration data from the electronic price tag device 12 is received by the receiver 11-6 of the ECR 11, the data receiver wait state is released (step A7), and the registration command is included in the received data. It is checked whether or not there is (step A8). Here, if the registration command is not included, the process returns to step A1 to cause a reception error. However, since the registration command is included in the received data, the process proceeds to step A9, and the PL in the received data is determined.
The PLU memory 11-4 is searched based on the U code, and the "product name" and "price" corresponding to the searched PLU code are read from the PLU memory 11-4 and displayed on the display unit 11-3. Here, the cashier operates the registration key RK after confirming that the product name of the product to be registered is displayed according to the displayed content. However, if another product name is displayed due to interference or the like, The user operates the clear key CK provided on the input unit 11-2. Now, if the clear key CK is operated, it is detected in step A11 and the process returns to step A1, and a reception error occurs. However, if the registration key RK is operated, it is detected in step A10. Step A
Proceeding to 12, the registration process of the product is performed.

The registration process can be performed by receiving the registration data from the ECR 11 as described above.
Of course, the registration process can also be performed by the PLU code input from the input unit 11-2 according to a normal key operation procedure. The registration process in this case is performed in step A13.
Is performed by other processing.

Modified Application Example (1) In the above embodiment, the electronic price tag device 12 is incorporated in a hanger. However, the electronic price tag device 12 may be incorporated in a placing device for placing a product, or of course, may be attached to the product itself. (2) Although the above embodiment is applied to the electronic price tag device 12, a small transmitter having no display function may be used.

[0024]

According to the present invention, since the price data of the product can be displayed by the small transmitter, there is no need to attach a price tag for displaying the price of the product in addition to the product label, and the displayed price data can be freely provided from an external device. Because it can be changed, there is no need to recreate and reattach price tags even if the price changes. Further, on the electronic device side, registration can be automatically performed based on the product identification data transmitted from the small transmitter, so that there is no need to manually input and register the registration data.
