An area R1 for storing a counter or the like for counting C _N and a sales registration file R2 for collecting sales data of each product sold at this electronic cash register by department, by cashier, by transaction, etc. are formed.

Further, in the RAM 20, a plurality of card data memories R3 and R4 having the same structure for storing card information corresponding to the card code read from the card reader 7 are formed. In each card data memory R3, R4, the card code, the initial amount set at the time of sale of this card (the sale amount of this card), the sale date of this card, and the total sales amount up to the present by this card Total amount of registration,
Area R5 that stores the card balance, etc., which is obtained by subtracting the total registration amount from the initial amount, and the registration date and time, the registration amount (total sales amount at that time), the electronic cash register No., when the sales registration was performed with this card. Cashier name, receipt No.
There are formed a registration detail area R6 for sequentially storing the above and a card registration amount area R7 for temporarily storing the amount to be paid by this card out of the total sales amount generated by the current sales operation.

FIG. 5 shows each memory formed in the RAM 33 of the file control unit 16. That is, an ECR No. area R8 for storing the electronic cash register No. of each electronic cash register connected to the file control unit 16, a data totaling area R9 for totaling various data, and issued (sold)
A card master file R10 for storing the card information of each card in all the cards is formed. This card master file R10 stores the same storage contents as the area R5 and the registration detail area R6 shown in FIG. 1 for each card. Area R5 card code, initial price, and card sales date data are set at the time the card is sold. And at the time of product sale, this card master file
Each card data of R10 is transferred to the file area R5 of the card data memories R3 and R4 of each electronic cash register and the registration details R6.

When the electronic cash register is powered on and various kinds of initial processing are completed, the CPU 17 executes the main routine according to the flowchart shown in FIG. That is, it waits for key data or a card code to be input at P1 or P2. When the card code is input from the card reader 7 at P2, the read card code is transmitted to the file control unit 16 via the transmission path 28. When receiving the card data of the corresponding card code from the file control unit 16, the card data is stored in the area R5 of the card data memory R3 or R4 of the RAM 20 and the registration detail area R6. Then, set the card input flag of area R1 to 1,
Add 1 to the card input number C _N. Then, the (card) tri-mark on the display unit 3 is turned on. If the data received from the file control unit 16 is an error message, an error is displayed on the display unit 3.

When key data is input from the keyboard 2 at P1, after confirming that the control key 15 is set to the [registration] work mode, check the type of the key data.
And if the key data is from the department key 9,
The department key process of FIG. 7 is executed. In FIG. 7, when the department key processing is started, the registering flag of the area R1 is set to 1, and the number entered by the number key 8 is added to the totalizer as the sales amount of the product. And the sales registration file
In addition to cumulatively registering in the corresponding section of the section file of R2, the section code and sales amount are printed out on the receipt 35 by the printer 24 as shown in FIG.

If the key data is P4 and the card key is 12 in the main routine of FIG. 6, it is determined that the card tightening operation has started, and the card key processing of FIG. 8 is executed. In the card key process of FIG. 8, when it is confirmed that both the registration flag and the card input flag are set to 1, the card input count C _N is checked. When the card input count C _N is 1, the total sales amount accumulated in the totalizer is compared with the card balance in the area R5 of the card data memory R3 in P5. When the card input count C _N is 2 or more, the card balance of each card data memory R3, R4 with the smallest card balance is compared. When the total sales amount is less than or equal to the card balance, the card code, the total sales amount, the current date and time, the electronic cash register No., the cashier name, and the receipt number are transmitted to the file control unit 16. Then, the cashier-specific file and the transaction-specific file of the sales registration file R2 are updated, and the total sales amount is stored in the card registration amount area R7. At the same time, the total sales amount is displayed on the display units 3 and 6. Then, as shown in FIG. 14, the card code to the receipt 35,
After printing out the card payment amount (card registration amount in area R7), send the receipt in blank without printing one line.

Next, in P6, the setting state of the dip switch is checked, and if it is in the off state, it is determined that the card balance is printed out on the same receipt 35 as the receipt 35 on which each sales data of the sale product is printed. Then, in P7, from the card balance of the area R5, the area R7
The card registration amount is subtracted, and the card balance after the subtraction is printed out on the receipt 35. Then, the cashier name, the receipt number, and the current time are printed, the receipt 35 is cut, and the receipt 35 is ejected from the receipt issuing port 4. After that, the registering flag, the card input flag, and the card input count C _N are reset to 0, and the totalizer and each card data memory R3, R4 are cleared.
This completes the card sales registration process for one customer, and returns to P1 or P2 of the main routine of FIG. 6 to wait for data input by the sales operation for the next customer.

If the date switch is off at P6 during card key processing in Fig. 8, the business of printing out the card balance on a separate receipt has started, so as shown in Fig. 15, the cashier name and receipt number ., After printing out the current time, perforations 36 are formed on the receipt 35. After that, after printing out the receipt title, date, and electronic cash register No., print out the same card code, the card balance up to the last time in the card data memory R3 (previous balance), and the card balance after this registration, and then P7 Proceed to and print out the cashier name etc.

In the card key processing of FIG. 8, when the total sales amount exceeds the card balance at P5, the shortage processing of FIG. 9 is executed. That is, the card code, the card balance, the electronic cash register number, the cashier name, and the receipt number are transmitted to the file control unit 16. Then, the cashier-specific file and the transaction-specific file are updated with the total sales amount. Next, the card balance in the area R5 is stored in the area R7 as the card registration amount. Then, the card balance is subtracted from the total sales amount to calculate the shortfall. And at P8, the card input count C _N is 1
In the case of, the shortage amount is displayed on the display unit 3 as shown in FIG. 17 (c). Then, as shown in FIG. 16, the card code and the card payment amount (card registration amount) are printed out on the receipt 35. Then, returning to the main routine of FIG. 6, deposit /
Wait for key input operation of the current total key 11 or input of supplementary card.

If the card input count C _N is 2 or more at P8 in Fig. 9,
When it is confirmed that the card balance of the other card data memory R4 is not 0, the card balance of the card data memory R3 of the previous card is set to 0 and, as shown in FIG.
Print out the card balance of "yen". Then, the smallest card balance among the card balances of the cards other than the card balance previously set to 0 is searched. When the search is completed, the process returns to P5 in FIG. 8 and the next smallest card balance is compared with the previously calculated deficit (total amount at this point).

In the main routine shown in FIG. 6, if the key data is the deposit / present total key 11 at P9, it is determined that the process for approving the total amount or the shortfall in cash has started, and the deposit / present of FIG. Performs the current total key processing. In the deposit / cash total key processing of FIG. 10, confirm that the registering flag is set to 1. If the deposit amount is entered using the numeric keypad 8, if the deposit amount is greater than or equal to the total amount (deficit amount) to be paid in cash, the total amount (deficiency amount) is classified by file and transaction by cashier. Update the file. Then, the total amount (the amount of fishing if there is a deposit amount) is displayed on the display units 3 and 6, and the drawer 5 is opened.
Then, as shown in FIG. 16, the total amount of cash payment (if there is a deposit amount, the deposit amount and the change amount) is printed out.

Then, check the card input flag on P10, and if it was cleared to 0, it was sold only in cash from the beginning, so the cashier name, receipt number, and current time are printed out, and after receipt is cut, a receipt is issued. To do. And
Clear the registering flag and totalizer.

If the card input flag was set to 1 on P10, the shortfall due to the card sales registration was paid in cash.
Returning to P6 in the card key processing of FIG. 8, the state of the dip switch is checked to determine whether the card balance of "0 yen" is printed out on the same receipt or another receipt.

In the main routine of FIG. 6, the key data is P11.
If it is the registration detail key 14, the registration detail processing of FIG. 11 is executed. That is, it is confirmed that the registration flag is cleared to 0, the card input flag is set to 1, and the card input count C _N is 1. Then, as shown in FIG. 19, the electronic cash register No., cashier name, receipt No., registration time, registration amount for each registration date recorded in the registration detail area R6 of the card data memory R3 are recorded on the receipt 35. The registration statement will be printed out in order. When the printout processing of all the registration data is completed, the total registration amount, the card balance, the cashier name, the receipt number, and the current time are printed out, and the receipt is cut and issued from the receipt issuing port 4. After that, the card input flag, the card input count C _N and the card data memory are cleared.

In the main routine of FIG. 6, the key data is P12.
If the card balance key is 13, the card balance process of FIG. 12 is executed. That is, if the registering flag is not set to 1 in P13, after confirming that the card input flag is set to 1 and the card input count C _N is 1, the card data memory R3 The card balance is read and displayed on the display units 3 and 6. Further, as shown in FIG. 20, the card code and the card balance are printed on the receipt 35. Then change the line and print out the cashier name, receipt number, and current time, and then issue the receipt. And
Clear the card input flag, card input count C _N , and card data memory.

If the registering flag is set to 1 in P13,
When it is judged that the card balance key 13 has been key-operated after the registration work of the sale item is started and it is confirmed that the card input flag is set to 1, this card balance key 13 is entered on the subtotal key 10 on P14. It is checked whether the key is operated after the operation. Then, before the subtotal key operation and when the card input count C _N is 1, the card balance of the card data memory R3 is displayed. When the card input count C _N is 2 or more, the total amount of the card balances of the card data memories R3 and R4 is displayed.

Also, on P14, operate the subtotal key 10 and then the card balance key 13
When is input by key and the number of card inputs C _N is 1, the amount obtained by subtracting the subtotal accumulated in the totalizer from the card balance of the card data memory R3 is displayed. If the card input count C _N is 2 or more, each card data memory
Displays the amount obtained by subtracting the subtotal amount from the total amount of R3 and R4 card balances.

For example, FIGS. 16 and 17 are views showing the print contents of the receipt 35 and the display contents of the display unit 3 showing the case where the card balance is less than the total sales amount. The case where the card balance up to the previous time is 2000 yen and the total sales amount this time is 2500 yen is shown. First
Figure 17 (a) shows the case where the card balance key 13 is entered after the registration operation is started and before the subtotal key 10 is operated. The card balance [2000 yen] and the (register) (card) tri-marks are displayed on the display unit 3. Light. The figure (b) shows the case where the card balance key 13 is operated after the subtotal key 10 is operated, and the subtotal amount is deducted from the card balance [-500 yen] and (registration) (card).
The (subtotal) tri-mark lights up. Moreover, the same figure (c)
Shows a case where the card key 12 is operated for card payment, and the shortage amount [500 yen] and (registration) (insufficient) tri-marks light up. Further, FIG. 7D shows the case where the deposit / cash total key 11 is operated to pay the shortfall in cash, and the total cash amount [500 yen] and (register) (total) tri-marks are lit. To do.

FIG. 13 is a flow chart showing the operation of the file control unit 16. That is, when data is input from each electronic cash register (ECR ₁ , ECR ₂ , ...) Via the transmission line 28, P15
Check the type of the data. Then, if it is the inquiry data of the card code, each card code of the card master file R10 of the RAM 33 is searched by the input card code. And when the corresponding card code is searched,
Each card data corresponding to the card code is read and transmitted to the corresponding electronic cash register. If the corresponding card code is not found, the card error information is returned.

If the input data on P15 is not card code inquiry but card registration data, the received registration date and time,
The registration amount, cashier name, and receipt number are the registration details area R6 of the corresponding card code in the card master file R10.
To be stored. At the same time, the total registration amount and card balance of area R5 with the same card code are updated.

With the electronic cash register configured as described above, the customer purchases a card in which the total purchaseable amount of the merchandise is displayed in the same manner as that for purchasing a gift certificate. Then, when shopping is done at each sales floor and the electronic cash register makes an approval, the card can be handed to the cashier. The cashier causes the card reader 7 to read the card code. When the card key 11 is operated after performing a normal registration operation for the sold product, the card code, card payment amount, and card balance after payment are displayed together with the department code and sales amount of each product as shown in FIG. A printed receipt 35 is issued.

In this way, the customer pays for the product in advance when purchasing the card, and the total sales amount is subtracted from the card balance each time the customer purchases the item, so the reliability of the card as a store side Since it is not necessary to investigate, it is possible to improve the efficiency of sales registration work using a card. Moreover, there is no concern that the payment will not be collected. Further, the price of the product can be deposited in advance. Furthermore, the customer does not have to bother to pay in cash.

In addition, since the card balance up to the present is printed on the receipt, it is possible to immediately understand how many yen the customer can purchase.

Further, as shown in FIG. 15, it is possible to issue only the card balance on a different receipt, so that the customer only needs to store the receipt with the card balance printed thereon, which simplifies the organization of the receipt.

Further, when the total sales amount exceeds the card balance, the shortage amount is displayed, and it is possible to pay only the shortage amount in cash, so that the card can be used effectively.

Further, when a shortage occurs, another card is read by the card reader, and the shortage can be paid with the card balance of the card inserted later.

Furthermore, when two or more cards are read by the card reader 7 before the operation of the closing key such as the card key 12, the card with the smallest card balance is paid in order. Therefore, customers do not need to bring many cards with a small balance.

Furthermore, after the card is read by the card reader 7, the card balance key 13 is keyed in, so that the card balance of the card can be known at any time.

Further, after the card is read by the card reader 7 and the registration detail key 14 is keyed in, as shown in FIG.
The total amount of each purchase (sales) purchased with this card so far,
Since the registration statement in which the purchase registration date and the like are printed on the receipt 35 is issued, it becomes very easy for the customer to manage the money.

Also, during the sales registration operation, if you operate the card balance key after operating the subtotal key 10 and before operating the closing key such as the card key 12, the amount after the subtotal is deducted from the card balance is displayed. As a result, the customer can see the amount and stop purchasing the remaining products at that time.
In addition, if the amount is a negative amount, it means that the key has not been operated yet, and the registered product can be canceled.

The present invention is not limited to the above embodiment. In the registration statement of the embodiment, as shown in FIG. 19, the date at each registration, the electronic cash register No., the cashier name, the receipt No., the registration time, and the registration amount are printed out. As shown in Fig. 21, even if only the date and registration amount are printed, the effect can be sufficiently achieved.
