Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a POS or ECR, and more particularly to a validity check of a key input operation of a deposit amount.

[0002]

2. Description of the Related Art In a POS or an ECR, when a customer and an operator transfer cash, they check and transfer the amount to each other, but the amount may be erroneously input by a key input operation. In such a case, there may be a problem between the customer and the operator, confusing where the error has occurred due to the transfer of the amount. According to Japanese Patent Application Laid-Open No. 1-173291 which prevents such a case, a sensor is provided in a drawer for storing cash by denomination, and the denomination that has entered and exited is checked, and a denomination larger than the change amount is provided. An electronic cash register that issues an alert when is output as change is disclosed. This check is
The purpose is to prevent accidental withdrawals of change.
It is impossible to detect and prevent erroneous counting of the deposit amount before calculating the change or erroneous key input operation. In particular, if you make a keystroke by mistake,
It is difficult to prevent trouble because it is a part that does not reach the customer's attention.

[0003]

SUMMARY OF THE INVENTION
The change amount is calculated from the total price of the product. Even if the operator correctly counts the received deposit amount, the operator does not always perform the key input operation of the received deposit amount correctly. The prior art could not prevent such careless erroneous operations performed by the operator himself.

[0004] It is an object of the present invention to prevent an operator from erroneously performing a key input operation of a deposit amount and calculating a change amount based on an erroneous deposit amount.

[0005]

Therefore, the validity check method of the deposit amount input according to the present invention includes a step of calculating the change amount by subtracting the total amount from the deposit amount entered by the key operation. When the change amount is minus, sending an error signal due to insufficient deposit amount or an error in key input operation; and when the change amount is `` zero '' or plus, the deposit amount is increased in the order of the denomination amount. Calculating the number of coins of each denomination by dividing the change amount in the order of the size of the denomination amount; and calculating the number of coins of each denomination. When it is `` zero, '' it is determined that the key input of the deposit amount is appropriate, and for the denomination whose change amount is not “zero,” the corresponding denomination number of the deposit amount is “zero.” Determining that the key input of the deposit amount is appropriate, and determining that there is an error in the key input operation of the deposit amount and transmitting an error signal when the number of denominations is not “zero”. It is characterized by including.

Further, in a processing device for processing input of bar code data and keyboard data in POS and ECR and outputting output data of a total price of goods and a change amount to a receipt and a display, a key input operation of a deposit amount is performed. A deposit amount input operation inspecting unit for determining the validity of at least one of the number of each denomination corresponding to the deposit amount and the calculated change amount is “zero”. And

[0007] Further, the deposit amount input operation inspection unit includes a change calculating means for calculating a change amount from the total amount of the deposit amount and the commodity price, and a change amount of the deposit amount and the change amount. The denomination number calculation means for calculating the number of each denomination, and comparing each denomination number of the deposit amount and each denomination number of the change amount, and decomposing the corresponding denomination number If either of the two is "zero" or both are "zero", the payment permission signal is sent out, and if both of the corresponding denominations are not "zero", the payment permission signal is not sent out It is characterized by comprising inspection means, and payment permitting means for permitting the output of the change amount data when the payment permitting signal is transmitted.

In the present invention, the validity of the key input of the deposit amount is checked by utilizing the fact that the denomination corresponding to the deposit amount and the change amount has the following rules. In shopping, etc., there is a case where payment is made with consideration for change. For example, if the total price of the merchandise is 3313 yen and the amount deposited from the customer is 3513 yen as payment 1, 35 yen as payment 2
Suppose there is a case of 20 yen. Payment 1 is a case where "I want fishing with 100 yen coin", but payment 1 at this time does not include a denomination of 100 yen coin. In payment 2, "10
0 yen, 5 yen, and 1 yen for each coin "
As in the case of payment 1, the deposit amount and the change amount do not include a common denomination.

Further, consider the case where the change amount is paid without being particularly conscious of the change amount in the above example. If you pay with a 5,000 yen bill, the denomination of the change amount will be “1,000 yen bill, 500 yen and 10 yen.
0 yen, 50 yen, 10 yen, 5 yen, and 1 yen. " If you pay with a 10,000 yen bill, the denomination of the change amount will be
"5,000 yen, 1,000 yen bills, 500 yen, 100 yen, and 50 yen
Yen, 10 yen, 5 yen, and 1 yen coins, and in both cases, the common denomination is not included in the deposit amount and the change amount.

As described above, without examining some examples, the rule holds that the same denomination does not overlap between the correctly input deposit amount and change amount. Therefore, when the denominations are duplicated between the deposit amount and the change amount, the deposit amount may have received the wrong amount or the correct amount with respect to the total amount of the product price, but may have It will be. In the above-described example, this corresponds to a case where a deposit amount such as 3600 yen or 4300 yen is erroneously input.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. The method according to the embodiment of the present invention will be described.
The change amount is calculated by subtracting the total amount of the commodity price from the input deposit amount (step 11). If the change amount is negative (N in step 12), an error signal is output due to a shortage of the deposit or a key input operation error (step 13). When the change amount is "zero" or positive (Y in step 12), the validity of the key input operation of the deposit amount is checked. The deposit amount is divided in order from the larger denomination to the smaller denomination to calculate the number of each denomination (step 14). Further, as for the change amount, the number of denominations of each denomination amount is calculated (step 15). For each denomination of the change amount, the number of each denomination of the deposit amount is confirmed for a denomination other than “zero”. Further, it is confirmed that the number of each denomination of the deposit amount is all "zero" (step 16). By comparing the number of denominations of the deposit amount corresponding to each denomination of the change amount, when at least one or both of the denominations is “zero”, it is determined that the key input operation of the deposit amount is appropriate ( In step 17 (Y), a payment permission signal is transmitted (step 19). When both the denominations of the deposit amount corresponding to the denomination of the change amount are not “zero” (N in step 17), it is determined that there is an error in the input operation of the deposit amount (N in step 17), and payment is permitted. No signal is sent (step 18).

Next, referring to FIG. 2 showing a method of decomposing the deposit amount and the change amount into denominations, the amount to be processed is divided by 10,000 yen to obtain a quotient and a remainder. The quotient becomes the number of denominations of a 10,000 yen bill (step 21). Next, the remainder obtained is divided by 5,000 yen to obtain the quotient and the remainder. The quotient becomes the denomination number of the 5,000-yen bill (step 22). Further, the obtained remainder is divided by 1,000 yen to obtain a quotient and a remainder. The quotient becomes the number of denominations of a 1,000 yen bill (step 23). Furthermore, the remainder is divided by 500 yen to obtain the quotient and the remainder. The quotient becomes the number of denominations of the 500 yen coin (step 24). Further, the remainder is divided by one hundred yen to obtain a quotient and a remainder. The quotient becomes the number of denominations of one hundred yen coin (step 2
5). Furthermore, the remainder is divided by fifty yen to obtain a quotient and a remainder.
The quotient becomes the number of denominations of fifty yen coin (step 26). Further, the remainder is divided by ten yen to obtain a quotient and a remainder. The quotient becomes the number of denominations of ten yen coins (step 27). Furthermore, the remainder is divided by five yen to obtain the quotient and the remainder. The quotient becomes the number of denominations of a five-yen coin (step 28). The remainder is the number of denominations of one yen coin (step 29). By executing steps 21 to 29 described above, the number of each denomination is obtained, and the corresponding denominations in step 16 are compared to check the validity of the input operation of the deposit amount.

Next, referring to FIG. 4 which shows a processing unit for adding a deposit amount input operation inspection unit in which this method is executed, this processing unit 30 is provided with a bar code reader and a keyboard to store bar code data and deposit data of goods. The processing unit 31 for inputting the keyboard data of the amount is processed by the processing unit 31
The validity of the key input operation of the deposit amount is checked based on the total amount of the commodity price and the deposit amount held in the inside, and a deposit amount input operation inspecting unit 32 for sending out a payment permission signal is added.

Referring to FIG. 3 showing the configuration of the deposit amount input operation inspection unit 32, the change amount 324 is calculated based on the deposit amount data 321 held in the processing unit 31 and the total amount data 322. Change calculating means 34
And denomination amount calculating means 35 for decomposing the deposit amount data 323 and the change amount 324 into denominations and calculating the number.
And the denomination validity checking means 36 for comparing the number of denominations corresponding to the deposit amount 323 and the change amount 324 to check the validity of the deposit amount input operation, and permits change payment based on the inspection result. Payment permitting means 37. The payment permitting unit 37 outputs the change amount data 327 to the processing unit 31 when the deposit amount input operation is appropriate based on the inspection result.

Further, the deposit amount input operation inspection section 32 outputs an error signal 328 to the processing section 31 to notify a warning when the denomination validity inspection means 36 detects an error in the input operation. Can be.

In the above embodiment, the deposit amount input operation inspection unit 32 has been described as being added to the processing unit 31. However, it is apparent that the deposit amount input operation inspection unit 32 can be modified to be incorporated into the processing unit 31.

[0017]

The first effect is that it is possible to prevent an operator from making mistakes in key input operation of the deposit amount in POS or ECR.

[0018] The reason is that when the deposit amount is erroneously input by a key with respect to the total amount of the commodity price, the change amount and the denomination are compared to warn of an error in the input operation. Because you can do it.

The second effect is that the validity checking means of the deposit amount input operation can be easily realized without requiring additional hardware modification for a normal POS or ECR processing device.

The reason is that the validity checking means of the deposit amount input operation can be realized by adding software means to the processing unit instead of hardware means.
