Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a designated cancellation processing device of a POS terminal having a commodity registration function, a discount / discount function, a designated cancellation function, and the like.

Conventional technology In a conventional POS terminal that has a product registration function, etc., there are both cases where a product with the same product code in the same receipt is discounted and registered without discount. When the designated cancellation is performed in the merchandise mode, the registered merchandise buffer in which the registered merchandise is temporarily stored is searched, and the first matched product is canceled. At that time, if the matched product is a product that is discounted and registered, the discount amount is also canceled at the same time.

Also, if you cancel the specified product code with the same product code registered in the same receipt at different discount rates, the registered product buffer that temporarily stores the registered product will be searched and It is configured to cancel products that have been matched to. At that time, the amount discounted from the matched products is also canceled.

Such a thing is similarly performed even when the discount is applied.

Problems to be Solved by the Invention If the registered product buffer is searched and the first matched product is canceled at the time of canceling the designation, there is a possibility that a product different from the product originally scheduled to be canceled may be canceled.

Means to solve the problem When the registered product buffer with the product code, the amount of money and the discount amount is set, and the product with the same product code in the same receipt is discounted and registered without discount In the state where both and exist, the designated cancellation mode setting means for setting the mode of the designated cancellation for canceling the commodity based on the commodity code, the input means for inputting the commodity code and the amount of money, and the inputted commodity code and the amount of money. By means of a search means for searching whether or not there is a registered product buffer and a search for whether or not a discount is registered when the corresponding product is available; Display means for displaying a discount amount to be input, and the corresponding product of the registered product buffer if there is no discount registration when the corresponding product exists by the search of the search means. If there is a discount registration, the product code, the amount and the discount amount of the corresponding product searched based on the input discount amount are deleted.

The same configuration is also applied when the products are registered with a certain discount rate.

Further, when the products with the same product code are registered with different discount amounts or with different discount rates, display means is provided for prompting the user to input the discount amount or discount rate.

When the designated cancellation set by the designated cancellation mode setting means is performed, a search is made to see if there is a corresponding product in the registered product buffer based on the product code and the amount of money. Delete the product code and amount of the product, and when the discount or discount is entered, delete the product code of the product that matches them by entering the discount amount or discount rate together with the amount and the discount amount or discount rate. Therefore, it is possible to reliably specify the product to be designated and canceled.

Also, when there are products registered with different discount amounts or different discount rates, the data of the products that match the entered discount amount or discount rate will be deleted together with the discount amount or discount rate. The product to be tried can be specified with certainty.

Embodiment An embodiment of the present invention will be described with reference to the drawings. First,
In the POS terminal, all the registered products in the same receipt are temporarily stored in the registered product buffer, such as the product code and price, and when the discount or discount is registered, the information is also stored at the same time. FIG. 3 shows the configuration of the registered product buffer.

In the POS terminal, if you want to cancel the designated registration of a product already registered in the same receipt, declare the designated cancellation, enter the product code and amount of the specified cancellation, and enter the registered product buffer according to the product code and amount. Search for.

This search process is shown in FIG. 2, and the entered product code and the amount of money are used as search keys to compare all the data in the registered product buffer from the beginning of the registered product buffer by the search means.

If the search key and the data in the registered product buffer match, turn on (= 1) the flag (FLAG1) for the corresponding product,
Check whether the discount is registered or not according to the discount amount area of the matched product code.

If there is discount registration, there is a discount amount flag (FLAG2)
ON (= 1). If there is a discount amount, check the same receipt key on the same receipt with the same search key and register with a different discount amount. If there is a different discount amount, a different discount amount flag (FLAG5) ON (= 1)
To do.

If there is no discount, check the discount rate area,
As with the discount, if there is a discount registration, the discount rate flag (FLAG3) is turned ON (= 1), and if a different discount rate is registered, a different discount rate flag (FLAG6) is set to O.
N (= 1).

If there is no discount or discount, the discount / no discount flag (FLAG4) is turned ON (= 1).

After the registration product buffer search process is completed, if there is no corresponding product (FLAG1 = 0), an error occurs.

In this way, the search processing is performed by the search means, and as a result, the various aspects operate as shown in FIG. In this case, the designated cancellation mode is set by the designated cancellation mode setting means such as a mode switch.

First, if there is a corresponding product (FLAG1 = 1), check whether discount registration or discount registration exists, and neither discount registration nor discount registration exists (FLAG2 = 0 and FLAG3 =
In the case of 0), it is possible to cancel the designation by the product code and the amount entered through the input means using the keyboard, and the data corresponding to the product code and the amount are deleted from the registered product buffer by the canceling means.

Next, only one of discount registration and discount registration exists, and different discount amounts or discount rates do not exist (FLAG2 = 1 and FLAG3 = 0 and FLAG4 = 0 and FLAG5 =
0, or FLAG2 = 0 and FLAG3 = 1 and FLAG4 = 0 and F
When LAG6 = 0), the specified cancellation based on the entered product code and amount is possible, and at the same time, the discount amount or discount rate is also canceled. Also, the data with the matching product code and price is deleted from the registered product buffer.

I) Discount registration and discount registration coexist (FLAG2 = 1, FLAG3
= 1) ii) Coexistence of discount registration or discount registration and no discount / discount (FLAG2 = 1 and FLAG3 = 0 and FLAG4 = 1 or FLAG2
= 0 and FLAG3 = 1 and FLAG4 = 1) iii) Different discounts or discount rates exist (FLAG2 = 1 and FLAG3 = 0 and FLAG4 = 0 and FLAG5 = 1 or FLAG2
= 0, FLAG3 = 1, FLAG4 = 0, and FLAG6 = 1), in any case, the display means displays a prompt to enter the discount amount or the discount rate. In the case of canceling the designated registration of a product that has been discounted or discounted, the operator inputs the discount amount or the discount rate. When the discount amount or the discount rate is not input, the discount amount and the discount rate are set to 0, and the registered product buffer is searched again. The search key is the product code, the amount of money, the amount of discount, and the discount rate. If they match, it is possible to cancel the designation and delete it from the registered product buffer. If they do not match, an error will occur.

As described above, the present invention does not discount the registered product buffer in which the product code, the amount of money, and the discount amount are set, and the case where the product having the same product code in the same receipt is discounted and registered. When both registered and existing exist, the specified cancellation mode setting means for canceling the specified goods based on the goods code, the specified cancellation mode setting means, the input means for inputting the goods code and the amount, and the inputted goods code And the amount of money are in the registered product buffer, and a search means for searching whether or not a discount is registered when the corresponding product is available; Display means for displaying a discount amount to be input by the input means, and the registered product buffer if there is no discount registration when the corresponding product is found by the search by the search means. If there is a discount registration for the product code of the applicable product and there is a discount registration, it consists of cancellation means for deleting the product code, price and discount of the applicable product searched based on the entered discount amount. Also, since the same configuration is adopted when the merchandise is registered with a certain discount rate, when performing the designated cancellation set by the designated cancellation mode setting means,
A search is made to see if there is a corresponding product in the registered product buffer based on the product code and the amount of money. If no discount or discount is applied, the product code and amount of the applicable product is deleted, and the product is discounted or discounted. If you enter the discount amount or discount rate, you can delete the product code of the product that matches them, along with the amount and the discount amount or discount rate, and thereby reliably identify the product you want to cancel. In addition, if products with the same product code are registered with different discount amounts or with different discount rates, display means is provided to prompt the user to enter the discount amount or discount rate. When there is a discount or a product registered with a different discount rate, this data is deleted in order to delete the data of the product that matches the entered discount or discount rate together with the discount or discount rate. Even if those having effects such can reliably identify the items to be specified cancellation.
