Abstract

PURPOSE:To simplify an operation of a register in case when a part of the amount is set to sale on credit, by storing a total amount of commodities purchased by a customer and an amount paid by the customer, and collecting its difference in a memory. CONSTITUTION:A total amount is displayed and printed by setting a mode key of a keyboard 1 of a cash register to registration, inputting a department, and a unit price and a quantity by an each department key 13 and a registering key 12 respectively, and depressing a sub-total key 143. In case when a customer has requested to pay in cash a smaller amount than a total amount and to make the balance sale on credit, a person in charge depresses a deposit/cash total key 144 and keys in 12 a paid amount. Subsequently, a customer's magnetic card is inserted into a card reader and a card sale key 142 is depressed. A printer prints a customer's number and a sale on credit data, and also they are stored in a magnetic cassette tape, too. In this way, it is unnecessary to separately handle payment in cash and sale on credit, and the work is simplified.

Description

[Detailed Description of the Invention] This invention is an electronic cash register (hereinafter referred to as ECR).
In particular, the present invention relates to an ECR capable of processing a single customer by combining cash transaction processing and credit sale processing using a customer card.

In the conventional ECR, transactions for products purchased by a customer can be carried out in cash or on credit using a credit card handed to the customer in advance. When credit sales are processed, it is necessary to request payment from the customer on a certain date, so the total amount owed to the customer is stored on a magnetic cassette tape storage device (JX's
FCMT). By the way, in conventional ECR, two types of transaction processing are possible as mentioned above.
If there is a request to sell the remaining products on credit, it is not possible to perform a combination of cash transaction processing and credit sale transaction processing. In other words, in conventional ECR, for one Il transaction, it is only possible to select either a cash transaction or a credit transaction, and it is not possible to process a mixture of both. could not. For this reason, when a customer makes the above-mentioned request, it is necessary to perform a cash transaction for products paid for in cash, and to perform a credit sale process for the remaining products after the transaction process is completed. For this reason, there are disadvantages in that the operation by the staff member becomes complicated and two receipts are required.

Therefore, the main object of the present invention is to provide an EOR that can perform a combination of cash transaction processing and credit transaction means.

To summarize this invention, the total price data of the products purchased by the customer is stored, and when the customer pays cash, the data of the cash amount is input and stored, and the difference data between the two is calculated. The data is configured to be collected by a data collection means.

The present invention will be described in more detail below along with embodiments shown in the drawings. □ FIG. 1 is a key arrangement diagram of a keyboard included in an embodiment of the present invention. In the figure, a keyboard 1 includes a mode changeover switch 11, a number key 12, a department key 13, and a function key 14.

The mode changeover switch 11 is used to switch between power off (OFF>), registration mode, and inspection mode (X).The numeric key 12 is used to enter amount data.The department key 13 is used to enter monetary data. The function keys 14 include a card sales key 142, a subtotal key 143, and a deposit/Im total key 144.The card sales key 142 indicates that the transaction is for credit sales using a customer card. The subtotal key 143 is operated to obtain the sum of the unit price data of a plurality of products input using the number key 12.

The leftover/II meter key 144 is for instructing that the transaction is a cash transaction, and constitutes cash transaction command means.

including.

4th all is a diagram for explaining the key operation sequence in one embodiment of the present invention, and FIG. 5 is a flowchart for similarly explaining the specific operation.

Next, the specific operation of one embodiment of the present invention will be described with reference to the 1m-th to 5th WJs. First, the 4th gm
In this Toramaro example, a customer purchases goods, pays 200 yen in cash out of a total of 600 yen, and requests that the remaining 400 yen be sold on credit. shall be. First, the clerk inputs the unit price data of the first product using the number keys 12. Accordingly, in CPU a line step (abbreviated as SP in the figure) 1, it is determined whether or not there is a key input signal from the keyboard 1. If there is a key input signal, it is determined in step 2 whether the input is from the numeric keys 12 or not. If the input is from the number key 12, one number data is transferred to the number buffer 42 in step 3.
Store length. That is, the unit price data of the first product is stored in the number buffer 42.

Next, when the clerk operates the department key 13, it is determined in step 2 that the number key 12 has not been operated, and in step 4 it is determined whether the department key 13 has been operated. The unit price voice data stored in the number buffer 42 in step 5 is stored in the amount buffer 743, and the number buffer 42 is cleared in step 6. Since the first product is registered in step 7, the N counter 47 is incremented. Then, in step 8, the storage area 48 specified by the N counter 47
The department code corresponding to the operated department key is stored at address 1, and the unit price amount data stored in the amount buffer in step 9 is also stored.

In step 10, the unit price data stored in the amount buffer 43 is added to the transaction total buffer 44,
In step 11, the department code and unit price data of the first product are printed by the printer 6. This operation is repeated to register unit price data and department codes for all products purchased by the customer. After completing the registration of all products, the clerk operates the subtotal key 143. Then, the CPU 3 proceeds to step 12 via step 1.2.4, determines that the deposit/II total key 144 is not operated, and determines in step 13 that the card sell key 142 is not operated. , step 14
&: It is determined that the subtotal key 143 has been operated. Then, in step 15, the transaction total buffer 44
The content of is displayed on display II5. If you look at this display, you can see that the total amount is 600 yen.

The customer sees the total display and selects a portion of it, for example 20.
When requesting to pay 0 yen in cash, the clerk inputs the amount data using the number keys 12. Then, the process proceeds to steps 1 to 3, and the amount data is stored in the number buffer 42. Then, in order to identify that the amount data is cash, deposit/I! Meter key′
144. Then, in step 12, it is determined that the deposit/II meter key 144 has been operated, and in step 16, it is determined whether or not the set number data is stored in the set number buffer 42. If the amount data is not stored in the W number buffer 42, the content of the transaction total buffer 44 is printed by the printer 6 in step 17. If the amount data is stored in the numeric buffer 42, the contents of the numeric buffer 42 are stored in the amount buffer 43 in step 18, and the contents of the numeric buffer 1 are stored in the numeric buffer 1 in step 19.
Clear the contents of 42. Then, in step 20, the contents of the amount buffer 43 and the contents of the transaction total buffer 44 are compared. When the content of the amount buffer 43 is smaller than the content of the transaction total buffer 44, that is, when the cash paid by the customer is less than the total amount, step 21
The N counter 47 is incremented. Then, in step 22, a code indicating cash is stored in the storage area 48 designated by the N counter 47, which stores the department code. Further, in step 23, the contents of the amount buffer 43 are stored in the corresponding unit price amount data storage area of the storage area 48. That is, the data of the cash paid by the user is stored in the storage area 48. This will be explained later in C
This is stored in order to collect the amount data received by MT7. In step 24, the contents of the amount buffer 43, that is, the amount data of the cash deposited by the customer, are printed by the printer 6. In step 25, the cash amount data stored in the amount buffer 43 is subtracted from the total amount stored in the transaction total buffer 44.

Here, in step 20 described above, if the cash paid by the customer is larger than the total amount, it is necessary to perform change processing. Therefore, if the cash is larger than the total amount, the process proceeds to step 26 -0 Then, in step 26 , the contents of the transaction total buffer 44 are subtracted from the contents of the amount buffer 43 and stored in the change buffer 45 . In step 27, the contents of the amount buffer 43, that is, the deposited amount data, are printed, and in step 28, the contents of the change buffer 45 are printed. Furthermore, in step 29, N
Counter 47 is cleared and the contents of transaction total buffer 44 are cleared in step 30. That is, if the amount of cash paid by the customer is greater than the total amount, change is processed and the series of operations is completed, and if they are equal, the operation is ended without performing change.

If the cash paid by the customer is less than the total amount and the remaining amount is to be sold on credit, the clerk operates the card sales key 142. Then, the CPU 3 determines in step 13 that the card selling key 142 has been operated, and proceeds to step 3.
Step 1 turns on the display lamp indicating a card reading request. This indicator lamp is included in the indicator 5. The clerk sees the display, receives the magnetic card from the customer, and has the magnetic card reader 8 read the customer number. Step 32
&-, it is determined whether or not the card has been read. If the card has not been read, the process returns to step 31 and the display lamp continues to be lit. If the card has been read, the customer number is stored in the card read buffer 41 in step 33, and the card data is checked in step 34. This is done by determining whether or not the read customer number is registered in a storage area (not shown) of the memory 4. If the card data check is normal in step 35, step 36
The customer number is printed using the printer 6. Furthermore, in step 37, *t of the transaction total buffer 144, that is, the amount data for credit sales is printed.

At step 38, the M counter 46 is passed. This is to designate each address of the storage area 48 because it is necessary to sequentially collect data stored in each address of the storage area 48 into the CMT 7. In step 39, the department code and unit price data are read from the address specified by the M counter 46 and provided to the CMT 7. Further, in step 40, the M counter 46 is incremented, and in step 41, the N counter 47 is subtracted. In step 42, it is determined whether the count value of the N counter 47 is 0 or not. If not, the process proceeds to step 39, and the department code and unit price data are read from the next address in the storage area 48 and provided to the CMT 7.

That is, the N counter 47 is incremented each time the department code and unit price data of the product purchased by the customer are registered, and is incremented when the cash paid by the customer is registered in the storage area 48. Until the key 142 is fully operated, the number of products stored in the storage area 48 is the sum of the number of cash payments. Therefore, when the CMT 7 collects each data of the memory tilted castle 48, the N counter 47
By subtracting the count value of and specifying 7 addresses of the storage area 48 with the M counter 46 until it becomes 0, all the data stored in the storage area 48 can be given to the CMT 7. When the count value of 47 becomes 0, in step 4a, the total amount due to the credit sale processing stored in the transaction total buffer 44 and the customer number stored in the card reading buffer 41 are given to the CMT 7.

Then, in step 44, the contents of the transaction total buffer 44 are cleared and the series of operations ends.

As described above, according to the present invention, the total amount of registered products and the amount of cash paid by the customer are stored, and when a credit sale transaction is instructed, the total amount and the full amount are stored. Since the data collection means collects receipts from customers, it is possible to perform a combination of cash transaction processing and credit sale transaction processing in accordance with the customer's request. Therefore, there is no need to separately perform cash transaction processing and credit transaction processing as in the past, which simplifies operations for the clerk.
