Next, the operation of issuing a receipt when a cash transaction is made in the POS terminal 1 will be described with reference to the flowchart shown in FIG. 3 (Step 1, Step 2 in the following description). .. Are described in S1 and S2), the merchandise code purchased by the customer is sequentially registered by the numeric key 12a of the keyboard 12, and the CPU 61
The product name / price etc. corresponding to the product code input from the PLU file 63a of No. 3 are called and stored in the buffer memory 63b. When the subtotal key 12c is operated after the end of the operation of registering all the commodities, the sales amounts of all the registered commodities, that is, the total sales amount of one transaction, are stored in the total sales buffer memory 63c.

Next, when the closing key 12d is operated in S2, the process proceeds to S3, where it is determined whether or not the transaction is a cash transaction. If the transaction is a cash transaction, the process proceeds to S4. In this step S4, it is determined whether or not the total sales amount stored in the total sales buffer memory 63c is equal to or more than the required amount of stamping (for example, 30,000 yen).
The determination is made by the CPU 61 executing the determination program stored in M62.

If it is determined in step S4 that the amount is less than the required amount for stamping, the flow advances to step S5 to perform a normal closing process. Then, a normal receipt (not shown), that is, a receipt in which a stamp attaching section described later is not printed, is issued. You.

If it is determined that the amount is equal to or more than the required amount for stamping, the process proceeds to S6, in which the stamp sticking column data, that is, a "frame" as shown in FIG. The character data of "Income stamp is attached to the back side" is sent to the printer drive circuit 36, and the printer 35 prints the receipt 80 in the stamp attaching section 80f including the frame and the character as shown in FIG.

Then, the process proceeds to S7, in which the CPU 6
Numeral 2 reads the number of stamps stored in the stamp number memory 63h, that is, the contents, adds "1" to the contents, and stores the added result in the stamp number memory 63h. Then, the process proceeds to S8, where the closing process is performed, and as shown in FIG.
a, price 80b, subtotal (corresponding to total sales) 80c, foreign tax 1 (corresponding to consumption tax) 80d, 31,50 to current total 80e
0 (corresponding to the total transaction amount) is printed and a receipt 80 is issued.

If it is determined in step S3 that the transaction is not a cash transaction, the process proceeds to step S9, and it is determined whether or not the transaction is a credit transaction. If the transaction is a credit transaction, the process proceeds to step S10. This S
At 10, it is determined whether or not the down payment in the credit sale is equal to or greater than the required amount for stamping. If the amount is less than the required amount for stamping, the process proceeds to S5 to perform a normal closing process. If the amount is equal to or more than the required amount of paper pasting, the process proceeds to S8 via S6 and S7 as in the case of the cash transaction, and the closing process is performed. In the case of this credit transaction, as shown in FIG. 8, a credit type 81a, a member number 81b,
Handling date 81c, handling number 81d, credit number 81
e, purchase price 81f, tax (consumption tax) 81g, total 81h,
A “credit sales slip” on which the down payment 81i, the total subtraction 81 and the like are printed, that is, a receipt 81 is issued.

Next, the operation in the case of the return process will be described with reference to the flowchart of FIG.

First, when a customer returns a product, S1
1. Return registration. This return registration is performed by inputting the return amount indicated on the receipt on which the revenue stamp is attached, the transaction total amount and the consumption tax amount separately from the keyboard 12, and operating the return key 12g. When the return registration is completed, the process proceeds to S12, and the closing key 12d is operated. When the closing key 12d is operated, the process proceeds to S13, where it is determined whether the transaction is a cash transaction.
When it is determined that the transaction is a cash transaction, the process proceeds to S14, and it is determined whether or not the total sales amount is equal to or greater than a stamping required amount.
If the amount is less than the required amount of stamping, the process proceeds to S15, where a closing process, that is, a return process is performed.

If it is determined in step S14 that the total sales amount is equal to or greater than the required amount of stamping, the flow advances to step S16 to read the contents of the stamp number memory into an amount corresponding to the transaction total amount. Is subtracted from "1", and the result is stored in the stamp number memory 63h. And
The stamp attached to the returned receipt is put into stock and reused.

If it is determined in step S13 that the transaction is not a cash transaction, the process proceeds to step S18, where it is determined whether or not the transaction is a credit transaction. If it is determined that the transaction is a credit transaction, the process proceeds to step S19. In S19, it is determined whether or not the down payment at the time of the transaction is equal to or more than the required amount for stamping. If the amount is less than the required amount for stamping, the process proceeds to S15 to perform the closing process, that is, the return process.

When it is determined that the down payment is equal to or more than the required amount of stamping, the process proceeds to S16, and the contents of the stamp number memory 63h corresponding to the down payment amount are read out.
"1" is subtracted from this content, and this content is stored in the stamp number memory 63h. In this case, the stamp attached to the returned "credit sales slip" is also collected.

Next, the operation when a receipt is issued together with a receipt will be described with reference to the flowchart shown in FIG.

First, after the normal registration is completed, the receipt issuing key 12f of the keyboard 12 is operated in S21. When the receipt issuing key 12f is operated, the process proceeds to S22, where it is determined whether or not the transaction is a cash transaction. If the transaction is a cash transaction, the process proceeds to S23, and it is determined whether or not the total sales amount is equal to or more than a stamping required amount. . If the result of the determination in S23 is less than the required amount of stamping, the process proceeds to S15 and a receipt is issued. In this case, since no stamping is required, a stamping field cannot be printed on the receipt.

If it is determined in step S23 that the amount is equal to or greater than the required amount of stamping, the process proceeds to step S25, where a stamping box 82e is provided as shown in FIG. ), And then proceeds to S26 to issue a receipt in which the total transaction amount obtained by adding the consumption tax to the total sales amount is printed. The number of stamps attached to the receipt is counted during the registration operation shown in FIG.

If it is determined in S22 that the transaction is not a cash transaction, it is determined whether or not the transaction is a credit transaction in S27. If the transaction is a credit transaction, a face value (excluding the consumption tax) must be attached to a stamp in S28. It is determined whether or not the amount is equal to or greater than the amount. If the amount is less than the required amount for stamping, a receipt is issued without printing the stamping area in S24. If the amount is equal to or more than the necessary amount for stamping, the stamping area is printed in S25. Then, a receipt is issued in S26.

To check the number of stamps used, select the "payment" operation with the mode switching key 14 and instruct the issuance of the stamp number report with the stamp number report issuing key 12f, as shown in FIG. The number of used revenue stamps and the amount 83d are printed together with the report creation date 83a, the division sales total 83b, the total sales total 83c, etc., and the stamp usage report 83 is issued. Therefore, it is confirmed from the used stamp number report 83 that two income stamps of 200 yen have been used, and that the income stamp can be accurately managed by comparing the used number with the stock number. It is.

FIG. 9 shows an example in which only two income stamps of 200 yen are printed in the case of a cash transaction. However, in the case of cash transaction, for example, one income stamp of 400 yen is used. If the payment is made, the contents are printed, and if a credit transaction is made and a revenue stamp is used in this transaction, the number of used papers and the amount of the revenue stamp are similarly printed. Things.

As described above, the POS terminal 1 has a C
Whether the total sales amount obtained based on the sales registration data of one transaction input from the keyboard 12 (input means) by the PU 61 (arithmetic means) is equal to or more than the required amount of revenue stamp pasting by the CPU 61 (sales total amount judgment means) If the amount is equal to or more than the required amount for attaching the stamp, the CPU 61 (counting means) adds 1 to the contents of the stamp number memory 63h, stores the result in the stamp number memory 63h, and inputs the result from the keyboard 12. Returned value of one transaction
When the PU 61 (return amount judging means) judges that the amount is equal to or more than the required amount for attaching the stamp stamp, the CPU 61 subtracts 1 from the contents of the stamp number memory 63h and stores the result in the stamp number memory 63h.
The number of stamps used can be ascertained with certainty, and verification against the stock stamps can be easily and reliably confirmed.
In addition, since the stamp number memory is provided for each transaction of cash transactions and credit transactions, and for each amount of revenue stamps, the number of stamps used and the number of inventory stamps for each transaction and each amount of revenue stamps are determined. Can be easily and accurately collated.

A keyboard 12 (input means) for issuing a receipt and inputting the amount of receipt is provided, and the amount of receipt is the total amount of sales, that is, the amount obtained by subtracting the consumption tax amount from the face value of the receipt, and the amount required for attaching the income stamp. A CPU 61 (receipt amount determination means) for determining whether or not
When the receipt issuance and receipt amount are input from the
When it is determined by 61 that the total sales amount out of the received amount is equal to or more than the required amount for attaching the revenue stamp, the printer 35
(Printing means) prints a stamp affixed column on the receipt together with the receipt amount, which is the sum of the total sales amount and the consumption tax amount. When the receipt is requested to be issued, the number of stamps must be counted. Irrespective of the fact that the receipt is printed with the receipt amount and the revenue stamp column printed, the management of the revenue stamp is not affected.

In the above-described embodiment, in the case of a return, the return amount is input. However, the return amount may be input.

[0050]

As described above, according to the first aspect of the present invention, the total sales amount obtained based on the sales registration data of one transaction input from the input means by the arithmetic means is calculated by the total sales amount determination means. Judge whether or not it is more than the required amount of stamping, and if it is more than the required amount of revenue stamping, add 1 to the contents of the revenue stamp number memory by the counting means, and return the amount of one transaction input from the inputting means When the return amount determining means determines that the amount is equal to or more than the required amount of the revenue stamp, the counting means subtracts 1 from the content of the revenue stamp number memory and stores the result in the revenue stamp number memory. As a result, the number of revenue stamps used can be grasped accurately and reliably, and the collation and confirmation with the inventory revenue stamps can be easily and reliably confirmed, so that revenue stamp management is ensured. It is those having the effect that the kill.

According to a second aspect of the present invention, in the first aspect of the invention, an input means for issuing a receipt and inputting the amount of receipt is provided, and whether or not the amount of receipt is equal to or more than the amount required for attaching the revenue stamp is determined. And a means for determining the amount of receipt
