ok Up) is stored in the PLU file, and an input device for inputting the product number of the purchased product is provided. Then, when the product number of the purchased product is input by the input device, the corresponding unit price is searched from the PLU file based on the product number, and the total purchase amount is calculated based on the searched unit price. The amount of money is displayed on the display unit or printed on a receipt and issued.

On the other hand, conventionally, an ECR using a bar code scanner as an input device has been developed and widely spread. That is, the product has a structure in which a bar code symbol including data of the product number of the product is attached, and the bar code symbol is optically read by scanning with a bar code scanner. In such a structure, when a bar code symbol is read by a bar code scanner, a signal indicating to the operator and the customer that the bar code symbol has been properly read is generally issued. Examples of such a signal include a buzzer sound and LE.
The light emitting display of D and the like have been generally used conventionally.

[0004]

As a product sales mode using the ECR, for example, in a supermarket, a convenience store, etc., every time the operator inputs the product number of a purchased product with an input device such as a bar code scanner, the product is sold. It is widely practiced to read out the product name and price of and to inform the customer of such information.
However, if such a sales mode is adopted, an excessive burden is imposed on the operator, which is inconvenient.

[0005]

According to the present invention, a PLU file storing a PLU (Price Look Up) including a product number and a unit price for each of a plurality of products, and data of the product number of this product attached to the product. A bar code scanner that optically reads the bar code symbol that includes the bar code symbol is provided, and the unit price corresponding to the product number included in the bar code symbol read by the bar code scanner is searched from the PLU file, and based on this searched unit price. A unit price expression means that emits a different sound depending on the unit price searched immediately after reading a bar code symbol by a bar code scanner in an electronic cash register of a structure that performs a product sales registration business in search of the price of a purchased product Was established.

[0006]

Therefore, immediately after the bar code symbol is read by the bar code scanner, a different sound is emitted by the unit price expression means according to the amount of the unit price retrieved from the PLU based on the product number data included in the bar code symbol. Be done. For example, the price range of the unit price is divided into units of 1000 yen or the like, and the higher the price range, the higher the pitch of the buzzer sound, or the amount of the unit price is output by voice. As a result, the unit price of the purchased product is indicated to the customer by sound, and the operator's burden is lightened. Moreover,
The sound emitted by the unit price expression means also serves as a signal indicating that the barcode symbol has been properly read.
