In the RAM 14, as shown in FIG.
Product information setting area 31 for product code, product name and unit price
The merchandise file 31 includes a, 31b, and 31c, cumulative areas 31d and 31e of sales points and sales amounts, and cumulative areas 31f and 31g of returned points and sales amounts. In the product file 31, in each of the information setting areas 31a to 31c, a product code, a product name, and a unit price of each product to be sold in the store are set in advance by a setting operation. In addition, the cumulative number of sales points and the sales amount 31
In d and 31e, the sales points and sales amount of each product registered for sale are accumulated for each product code.
Similarly, the cumulative areas 31f, 3 for the number of returned items and the amount of returned goods
In 1g, the number of returned items and the returned amount of each registered product are accumulated for each product code. In addition,
The content of each of the accumulation areas 31d to 31g is set to "0" every time a settlement report of the product file 31 is issued by the settlement business.
Cleared.

The CPU 11 is program-controlled to execute a return key process shown in FIG. 5 in response to a key input of a return key 2f of the keyboard 2. That is, when the “registration” mode is selected by the mode switch 3, the return key 2 is input via the keyboard controller 18.
When the key signal of f is received, the state of the return key flag F is checked. If the flag is set to "1", the flag is reset to "0" to set the sales registration mode,
If it has been reset to "0", it is set to "1" to set the return registration mode, and this key processing ends.
(Mode Switching Means) If the return key 2f is input in a mode other than the "registration" mode, the key input is regarded as an error.

The CPU 11 is program-controlled to execute a scanning process shown in FIG. 6 in response to a bar code reading operation by the bar code scanner 8. That is, when the “registration” mode is selected by the mode switch 3, the scanner interface 2
When the bar code data is fetched through the second key 2, the return key flag F is checked. If the flag F is reset to "0", the bar code of the product is read in the state where the sales registration mode is selected. The file 31 is searched to read the product name and unit price corresponding to the product code. (Information reading means)

Next, the sales point and sales amount accumulation area 31 corresponding to the product code in the product file 31
The d and 31e are cumulatively processed with 1 as the sales point and unit price as the sales amount. (Sales registration processing means)

Further, the product code is converted into a bar code. Then, the printer 20 prints the bar code obtained by this conversion together with the above-mentioned product name, unit price, sales quantity, and sales price, and finishes the process.
(Receipt printing control means)

On the other hand, if the return key flag F is reset to "1", the bar code of the product is read while the return registration mode is selected.
The bar code is converted into a numeric code, that is, a product code (bar code conversion means), and the corresponding product name and unit price are read from the product file 31 using the obtained product code as a key (information reading means). 31
In the return point and return amount accumulation areas 31f and 31g corresponding to the commodity code, 1 is returned as the return point and the unit price is returned as the return amount. (Returned goods registration processing means) If a barcode reading operation is performed in a mode other than the “registration” mode, the reading operation is regarded as an error.

Further, the CPU 11 is program-controlled to execute a code key process shown in FIG. 7 in response to a key input of a code key 2c of the keyboard 2. That is, when the key signal of the code key 2c is fetched via the keyboard controller 18 in a state where the "registration" mode is selected by the mode switch 3, numeric data is inputted by the numeral key 2a immediately before the input of the code key 2c. It is determined whether or not a numeric input has been entered. If it has been input, the numeric data is recognized as a product code, and the same process as the barcode (product code) scanning process shown in FIG. 6 is executed.

Note that the code key 2 is used in modes other than the "registration" mode.
If c is key-input, or if the code key 2c is key-input in a state where the code is not set, the key-input is regarded as an error.

In the present embodiment having such a configuration, by selecting the "registration" mode by the mode switch 3, it becomes possible to register the sale of the product purchased by the customer. In this state, the bar code attached to the product is read by the bar code scanner 8 or the numeric key 2 on the keyboard is read.
When a product code of a product is inputted by a key using a and the code key 2c, the sales data of the product is accumulated in the sales point and sales amount accumulation areas 31d and 31e of the product file 4 for each product code. At this time, the receipt shows the product code of the product along with the product name (chocolate), unit price (single 200), number of sales (1 ×), and sales price ($ 200), as shown in FIG. The barcode 81 is printed out.

On the other hand, if the customer offers to return the merchandise, the customer is requested to present a receipt when he / she purchased the returned merchandise. If the returned product is indeed purchased at the store, the bar code 81 of the product code is printed on the receipt together with the sales data of the returned product, so the return key 2f is entered and the return registration mode is entered. After the designation, the barcode scanner 8 reads the barcode 81 of the returned product on the receipt and performs an operation. Then, the return data of the corresponding product is accumulated in the return point and return amount accumulation areas 31f and 31g of the product file 4 for each product code.

As described above, according to this embodiment, the product code of the product is converted into a bar code together with the sales data of the product purchased by one customer, and the bar code is printed out on the receipt.
At the time of return registration, the barcode of the returned product printed on the receipt can be registered simply by reading the barcode with the barcode scanner 8, so that the product code input operation at the time of return registration is simplified. Eliminates mistakes in entering product codes.

Even if the barcode is not attached to the product, the barcode of the product is printed on the receipt. There is also an advantage that a scanning operation by the barcode scanner 8 can be used.

In the above-described embodiment, the bar code of the registered product is printed upon receipt of registration every time the product is registered. However, a memory for storing the product code of the sales registered product for one transaction is provided, and the closing key is provided. The barcodes of all the products purchased by one customer may be collectively printed on receipt by key input of the (deposit / current total key 2e).

If a bar code is attached to the returned product, the return registration can be processed by reading and operating the bar code, so that it is possible to determine whether or not the sales registered product is a product with a bar code. May be provided, and the barcode of the product code may be printed on the receipt only in the case of sales registration of the product without the barcode. This can save receipts.

In addition, the bar code scanner 8 may be of a fixed type, or the mode of switching between the sales registration mode and the return registration mode may be changed by a method other than the return key 2f. It is needless to say that the embodiment can be modified.

[0028]

As described above in detail, according to the present invention, it is possible to perform a return registration operation by reading a bar code of a product code in the same manner as in the sales registration operation, and furthermore, it is possible to return the returned product together with the receipt confirmation. , It is possible to provide an electronic cash register that can easily and reliably perform a return registration operation.
