Description of the Related Art In an electronic cash register (hereinafter simply referred to as a cash register) having both of the above-mentioned settlement functions, a difference is usually provided in the commodity price between cash settlement and prepaid card settlement. . On the other hand, in this type of conventional register, the settlement method is determined before registering the sale product in the register.

[0003]

Therefore, when the settlement method is changed during the registration of the product in the register, it is necessary to once cancel all the registered products in the register and then register the product again from the beginning. There is a problem that unnecessary work occurs and the waiting time of the customer becomes longer. Also,
Since the receipt issued by the register is printed at the same time as the product registration, there is a problem that a useless receipt is generated by re-registering the product. Therefore, an object of the present invention is to prevent the register operation from being wasted even when the settlement method is changed on the way.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention aims to solve the above-mentioned problems by determining a settlement method when a sales transaction is confirmed. That is, the present invention has a cash settlement function and a prepaid card settlement function, and an electronic cash register having a difference in the commodity price between the cash settlement and the prepaid card settlement. A product price difference area for storing the price difference from the price is provided in the memory, and the total sales price is added up by the cash settlement price when the sales product is registered, and the price difference of the sales product is calculated by the product price difference area. The payment method is determined when the sales transaction is confirmed, and if the payment method is a prepaid card payment, the total amount of the price difference is subtracted from the total sales price at a time (claim).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
For example, an embodiment of the present invention in an employee cafeteria will be described. Here, FIG. 1 is a control block diagram of the register, and FIG. 2 is a flowchart showing the control operation of the register. First, in FIG. 1, a CPU 1 for controlling a register includes a memory 2, and a program to be executed by the CPU 1 and control data are stored in the memory 2. The control data includes
A cash settlement price (hereinafter referred to as a cash price) a1, a2, a3... An when each product is sold by cash settlement, and a prepaid card settlement price (hereinafter referred to as a prepaid card price) when sold by prepaid card settlement. ) B1, b
2, b3... Bn are included. Further, the memory 2 is provided with a storage area 2a for the total sales price c and a storage area 2b for the total price difference d. The input key 3, the display 4, the printer 5, and the card reader / writer 6 are input / output units of registers for inputting / outputting data to / from the CPU 1.

Next, a control operation according to the present invention will be described with reference to FIG. Before product registration, total sales price c
The initial data of the storage area 2a of “1” is “0” (S1), and the initial data of the storage area 2b of the total price difference d is also “0”.
(S2). Here, the operator registers the product specified by the customer by pressing the input key 3 assigned to the register (S3). The CPU 1 determines whether there is a price difference between the cash price ak of the registered commodity and the prepaid card price bk (S4), and if there is a price difference, stores the price difference (ak−bk) in the storage area 2b. (S5). Next, the cash price ak is stored in the storage area 2a (S
6). If there is no price difference in S4, the process immediately proceeds to S6. Thereafter, it is determined whether the sales transaction has been determined (S7). If not determined, the process waits for the next product registration in S3. If there is a next product registration, the next sales price and product price difference are accumulated and stored in the storage areas 2a and 2b by repeating S4 to S6.

When the product registration is completed, the operator presses the “current total / custody” key of the input keys 3. The CPU 1 determines that the sales transaction is finalized by this key operation (S7), and confirms whether or not a prepaid card is inserted in the card reader / writer 6 at this time (S8). If the prepaid card has been inserted, it is determined that the payment is prepaid card settlement, and the total price difference d of the storage area 2b is subtracted from the total sales price c of the storage area 2a (S9).
Next, the total selling price c after the subtraction is subtracted from the remaining amount of the prepaid card, the remaining amount of the prepaid card is rewritten (S10), and the prepaid card is discharged (S1).
1), end the process. On the other hand, if the prepaid card is not inserted in S8, it is determined that the payment is in cash, the change is paid out (S12), and the process ends.

In the above-mentioned register, the settlement method is determined when the sales transaction is confirmed. Therefore, even if you start product registration by prepaid card payment by inserting a prepaid card first, if you switch to cash payment by extracting the prepaid card before finalizing the sales transaction,
It is possible to change to cash settlement while keeping the previous product registration operation. Conversely, even if you start merchandise registration by cash settlement, if you switch to prepaid card settlement by inserting a prepaid card before finalizing the sales transaction, the settlement method can be easily changed. In addition, useless printing of the receipt due to redoing the register operation is reduced. Note that the determination of the settlement method is not limited to the presence or absence of insertion of the prepaid card, but may be based on an operation signal from the input key 3. Further, the register according to the present invention is not limited to a cafeteria, but can also be applied to the sale of merchandise in a general store such as a shop. Means such as inputting a product code from a key can be used as appropriate.

[0009]

As described above, according to the present invention, the settlement method can be freely changed before the sales transaction is confirmed, so that the number of re-operations of the register is reduced, the load on the operator is reduced, and the waiting time for the customer is reduced. Is shortened. Also, the occurrence of useless receipts is reduced.
