Further, whether or not a multiplier input is instructed by the multiplication key is determined from a multiplication flag or the like set in response to the operation input of the multiplication key. Then, for example, when this multiplication flag is reset to “0” and it is determined that there is no multiplier input, the single item registration process, that is, the number of sales items of the sold product is set to “1”, and the sales amount is set to the unit price, The sales data was being registered. On the other hand, when the multiplication flag is set to “1” and it is determined that the multiplier is input, the multiplication registration process, that is, the sales point of the sold product is set as the multiplier, and the sales amount is set as the product of the unit price and the multiplier. The data was being registered.

It should be noted that the control unit determines that an operation error occurs if the multiplication flag is not set even if the numerical data is numerically input by the numerical keys before the barcode is read and input by the barcode scanner. Or, it was processed as a single item registration. This is because the numeric keypad is not only used to enter the number of sales points, but is also used to enter numerical data such as department code, discount amount, discount rate, deposit amount, etc., if necessary. It was a measure because it could not be determined that it was a sales score.

Therefore, when registering a plurality of sales of the same product by using this type of product sales registration data processing device, the operator first enters the number (score) of the same product by using the registration key, and then Enter the multiplication key to enter
Any one of the same product by barcode scanner
The registration operation was performed by scanning the barcode attached to the product.
