Description

FIELD OF THE INVENTION This invention relates to electronic cash registers (hereinafter referred to as ECRs), and more particularly to improvements in ECRs that include, for example, a cash drawer for storing money.

Description of Prior Art Conventionally, there have been ECRs that can perform registration processing not only for cash but also for credit cards, checks, gift certificates, etc.

In such an ECR, payment keys are provided for each type of payment method. Then, depending on which method the customer uses to pay for the product, a corresponding payment key is operated.

In the ECR, registration processing is performed in accordance with the operated payment key.

By the way, ECRs are generally provided with a cash drawer for storing money. As mentioned above, conventional EC allows transactions to be settled using multiple payment methods.
In R, the cash drawer was opened each time the payment key was operated. In other words, the conventional E
CR was designed to open the cash drawer unconditionally when the payment key was operated, regardless of the type of payment method. However, when paying by credit card, for example, there is no need to open a cash drawer because no money is exchanged with the customer on the spot. Also,
Depending on the store, when payment is made with a check or gift certificate, the check or gift certificate received from the customer is not necessarily placed in the cash drawer, and there may be cases where there is no need to open a cash drawer. Ta. In this way, opening the cash drawer even when there is no need to open the cash drawer increases the chance that the money in the cash drawer will be stolen or lost, which is undesirable. Furthermore, since the operator must open the cash drawer more times than necessary, there is also the drawback that the burden on the operator becomes heavy.

OBJECTS OF THE INVENTION Therefore, the main object of the invention is to provide an ECR in which the cash drawer is opened only when necessary.

Structure and Effects of the Invention To summarize, the present invention has a plurality of 8! Information on whether or not to open a cash drawer is set and stored for each type of payment method, and when information representing a payment method is input, whether or not to open a cash drawer is controlled based on the corresponding stored information. It was designed to be in charge.

According to this invention, since the cash drawer is opened only when a predetermined payment key is operated, it is possible to reduce the chances of money in the cash drawer being stolen or lost.

Furthermore, the number of times the operator opens the cash drawer can be suppressed to the necessary minimum, so the burden on the operator can be reduced.

Hereinafter, this invention will be described in more detail with reference to embodiments shown in the drawings.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a schematic block diagram showing an embodiment of the present invention. In the figure, CPU1 includes ROM2 and RAM.

6 and 7 are flowcharts for explaining the operation of the embodiment of FIG. 1. In particular, FIG. 6 shows the operation in the setting mode, and FIG. 7 shows the operation in the registration mode.

The operation of the embodiment shown in FIG. 1 will be described below with reference to FIGS. 4 to 7.

First, the operation in the setting mode will be explained with reference to FIGS. 4 and 6. In this setting mode,
Payment key flags 85 to 38 shown in FIG. 3 are set. First, as shown in FIG. 4, press "1" on the number key 42.
key or the "0" key is operated. Therefore, the sixth
At step 1 (abbreviated as S in the figure) shown in the figure, it is determined that there is a key input, and the process proceeds to step 2, where it is determined that the operated key is the numeric key 42.

Then, proceed to step 3, and enter the input number data (1
Alternatively, O) is stored in the gastric powder buffer y (NB) 32. Next, in step 4, the numeric flag (FN)
31 is set. Then, return to step 1 again.

Next, as shown in FIG. 4, one of the payment keys 44 is operated. This payment key operation is
The decisions are made in steps 1.2 and 5 shown in FIG. Then, the process proceeds to step 6, where it is determined whether the same number flag 31 is set. If the number flag 31 is not set, it is determined that the key operation procedure is incorrect, and error handling is performed in step 7.

- On the other hand, if the numeric flag 31 is set,
Proceeding to step 8, which key among the payment keys 44 was operated and the contents of the numeric buffer 132 are printed on the printer 6. Next, proceed to step 9,
Payment key flags 35 to 3 corresponding to the operated payment key
The numerical data of the numeric buffer 132 is stored in 8. Thereafter, the process advances to step 11, where the numeric buffer 3263 and numeric flag 31 are cleared, and the process returns to step 1 again.

The above operation is repeated and the payment key flags 35 to 38
is set to numerical data of either [0] or "1". Here, the payment key flag set to "1" indicates that the carriage cord lower 7 will not be opened when the corresponding payment key is operated later in the registration mode. Further, a payment key flag set to "0" indicates that the cash drawer 7 is opened when the corresponding payment key is operated in the registration mode.

Next, the operation in the registration mode will be described with reference to FIGS. 5 and 7. In this case, as shown in FIG. 5, first, the price data of the product is input using the numeric keys 42. The operation of this numeric key 42 is determined in steps 21 and 22 in FIG. 7, and the input amount data is stored in the numeric buffer 32 in step 23. Then, in step 24, the numeric flag 31 is set.

Next, as shown in FIG. 5, one of the department keys 43 is operated. This department key operation is done in step 2.
1.22 and 25 are determined, and the process proceeds to step 26.

In step 26, it is determined whether the same number flag 3'1 is set.

If the number 7 lag 31 is not set, it is determined that the key operation procedure is incorrect, and error processing is performed in step 27. On the other hand, the number flag 31 is set to Sera I.
If so, the process proceeds to step 28, where the amount stored in the same number buffer 32 and the department name corresponding to the department code inputted from the department key 43 are displayed on the display 5. Furthermore, in step 29, the above-mentioned amount, department name, etc. are printed on the printer 6. , Lvt, and in step 30, the amount data in the number buffer 32 is tampered with in the registration amount M1 area (lM) 33. Then, in step 31, the number flag 31 and the number buffer 32 are cleared, and in step 32, the department registration flag (FS) '34 is set. After that, the process returns to step 21.

The above operations are repeated for each product.

When the registration of the product after R is completed, the operator receives the payment from the customer, and the received payment is input using the numerical keys 42. However, if the payment is not received on the spot, such as a credit card, the registered total amount is entered as is. Thereafter, one of the payment keys 44 is operated. If customer M pays with a credit card, the credit key 441 is operated, if the customer pays with a check, the check key 442 is operated, and if the customer pays for something other than the product, the subtotal key 443 is operated. If payment was made in cash, press main 1 key 4
44 is operated.

The above-mentioned operation of the payment key 44 is performed in step 21. of FIG.
22.25 and 33. Then, the process proceeds to step 34, where it is determined whether or not the number 7 lag 31 is set. If the numeric flag 31 is not set, there is an error in the key operation procedure! 'IIvfT
Then, in step 27, error processing is performed.

On the other hand, if the number flag 31 is set, the process proceeds to step 35, where it is determined whether the department registration flag 34 is set. If the department registration flag 34 is not set, it is determined that there is an error in the key operation procedure, and error handling is performed in step 27. On the other hand, if the department registration flag 34 is set, step 36
Then, it is determined whether the stored content of the number buffer 32 (data indicating the amount received from the customer) is greater than or equal to the transaction total amount in the transaction total area 33. If the stored content of the number buffer 32 is smaller than the total transaction amount in the transaction total area 33, the predetermined process <tJNDERTEND
ER processing) is performed. On the other hand, number buffer 3
If the number data set in No. 2 is equal to or greater than the total transaction amount in the transaction total area 33, it is determined that registration is possible, and the process proceeds to step 37, where the change is displayed on the display 5.

The change displayed at this time is obtained by subtracting the transaction total amount in the transaction total area 33 from the stored content f)) of the number buffer 32. Next, the process proceeds to step 38, where the payment amount and the like are printed on the printer 6.

Next, the process proceeds to step 39, where it is determined whether "1" is stored in the payment key flags 35 to 38 corresponding to the payment key 44 operated at that time. If "1" is stored, the process directly advances to step 41. On the other hand, “1
” is not stored, that is, if “0” is stored, the process advances to step 40 and the cash drawer 7 is opened. Then, proceed to Stesive 41. Step 4
1, the numeric flag 31. Placement buffer 32. The transaction total area 33 and department registration flag 34 are all cleared. After that, the process returns to step 21.

As mentioned above, in this embodiment, payment key flags 35-
Depending on whether "1" or "0" is stored in 38, whether or not to open the cash drawer 7 is controlled. Therefore, the cash drawer 7 can be opened only when the payment key required to open the cash drawer 7 is operated.
