Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic cash register that can eliminate the need to prepare change for amounts less than a predetermined unit, and more specifically, uses a card together with cash as a payment medium, and the payment amount for less than the predetermined unit is made by using the card. This article concerns an electronic cash register that eliminates the need to prepare change by recording the information on the electronic cash register.

In retail stores and supermarkets that sell food, daily necessities, etc., unit prices are often set in increments of 1 to 10 yen. For this reason, it is necessary to prepare change of 100 yen, 5 yen, 10 yen, and 50 yen, and it is necessary to take in and out 3 to 5 digit change for each transaction, but these tasks are troublesome and 1. Easy to make mistakes. In addition, there are problems such as the total amount of change reserves in supermarkets and the like, requiring a large amount of operating funds.

The present invention has been made in view of the above-mentioned problems, and aims to eliminate the need to prepare small change at retail stores and supermarkets, reduce the amount of reserve money, and reduce the work of the cashier. In order to achieve this objective, the present invention has an electronic cash register that is equipped with a keyboard, a display section, a printer, a memory, and a central processing unit, and that registers the product. a card league to read, a calculation means for settling the sum of the total amount calculated by product registration and the carryover amount for each predetermined adjustment unit and calculating the amount less than the adjustment unit as a new carryover amount; and a card reader for recording the carryover amount on the card.

In the electronic cash register of the present invention, a card such as a magnetic card is used, and this magnetic card is provided with a carryover amount column in which the previous change is recorded, which is read out for each transaction and added to the total amount of the transaction. After that, record the 19 fractions less than 100 yen and 50 yen again. Eliminating fractional change through this operation 1. The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of an electronic cash register (hereinafter referred to as ECR) according to an embodiment of the present invention. The ECR in Figure 1 is a central control unit (CPU), 1,
Card reader 2. Card writer 3, keyboard 4. It is equipped with a memory 51, a display 6, a printer 7, etc.

The CPU 1 reads the card reader 2 .in accordance with the processing program stored in the memory 5 . Card writer 3. keyboard 4
, controls input/output devices such as the display 6 and the printer 7,
Monitoring of operating procedures and data transfer.

Performs processing and various calculations.

Cart reader 2 is for reading magnetic card information.

The card writer 3 is for recording onto a magnetic card.

It is preferable that the card reader and card writer 3 be integrally formed and capable of continuously reading data from and writing data to the card. It may also be used by being connected by a conveying means. Further, although a magnetic card is used as the card in this embodiment, other carts such as an IC cart may be used as long as data can be erased and written on. This card records the amount carried over as a result of settlement for each transaction. This card further records a store code, customer code, expiration date, and adjustment unit as described below, as necessary.

The keyboard 4 has keys and σO~9 as shown in Figure 2.
Numeric keypad 41 consisting of numeric keys. Clear (
CL) key 42, a department key 43 for inputting the department code DPI-DP8, a subtotal key 44 for printing the transaction total, and a cash key 45 for inputting the payment amount.

Memory 5 includes read-only memory (ROM) for programs that determine the operation of CPU 1, and random access memory (RA) for various work areas and buffers.
M) Consists of. Here, a buffer area for the total amount, adjustment amount, and billing amount is provided in the RAM. Note that among the data recorded on the magnetic card described above, the expiration date, adjustment unit, etc. may be stored in the memory 5.

The display 6 displays numerical values entered using the numeric keypad 41, the total amount, change, etc. The printer 7 is used for product registration and printing of payment amounts.

Next, the operation of FIG. 1 will be explained with reference to the flowchart of FIG. 3. Referring to FIG. 3, first.

Normal product registration is performed, and when the subtotal key 44 is pressed, the total amount is displayed on the display section 6. Here, when the magnetic card is inserted, a card update process to be described later is performed, and then the billed amount is displayed and the printer 7 prints out the billed amount. Next, when the manual input and cash key 45 for the deposited amount is pressed, the billed amount and the deposited amount are compared, and if the deposited amount is insufficient, the system waits for additional input of the deposited amount. When the deposited amount is equal to or greater than the billed amount, change is displayed, and after the deposited amount and change are printed, the operation ends.

Next, the cart update processing operation in the ECH in Fig. 1 is explained in the fourth section.
This will be explained with reference to the flowchart shown in the figure. When a cart is inserted after normal product registration operations and pressing of the subtotal key, the ECR performs cart update processing shown in the flowchart of FIG. 4. First, the data recorded on the card, such as store code, expiration date, and carryover amount, is read. Next, it is determined whether or not the store codes match and whether or not the expiration date has passed. If one store code does not match or the expiration date has passed, error processing such as issuing an error warning is performed. In the above judgment, if it is determined that the store code matches and the card is within the expiration date, add the carryover amount taken from the card to the total amount in the product registration mentioned above and store it in memory 5. Store it in the provided adjustment amount area. For example, if the total amount is 1013 yen and the carryover amount is 25 yen, the adjustment amount will be 1038 yen. Subsequently, the remainder obtained by dividing the adjustment amount by the absolute value of the adjustment unit is stored in the carryover amount area in the memory 5. In the above example, if the absolute value of the adjustment unit is 100 yen, the quotient is 10 and the remainder is 38 yen, and this remainder is 3
8 yen will be the new carryover amount.

In addition, the adjustment unit is given a positive or negative sign, and when a store lends the carryover amount to a customer, the adjustment unit is positive, and conversely, when a store borrows from a customer, it is negative. Next, determine whether the adjustment unit is positive or negative, and if it is positive, leave it as is; if it is negative, the sum of the adjustment unit (1100 yen in the above example) and the new carryover amount (+38 yen) is further updated. Memory 5 as the carryover amount (-62 yen)
Store the amount in the carryover amount area and proceed to the next step. Next, subtract the carryover amount ゛・(+38 yen or 162 yen) from the adjustment amount (1038 yen) and store it in the billing amount area in the memory 5, and write the carryover amount on the card with the card writer 3.
The billed amount (1,000 yen or 1,100 yen) is displayed on the display section 6, and the cart update process is ended.

As described above, according to the present invention, cash is exchanged in units of adjustment or more, and fractional change is recorded in the cart, which reduces the cashier's change work and reduces mistakes.
can be done. Further, change may be prepared for denominations of more than the above-mentioned adjustment unit. Furthermore, if you record the amount borrowed from customers on your card, you will indirectly have customers pay a portion of the change reserve, which will reduce the operating funds for each store.

Additionally, in order to encourage customers to use such cards, or to prevent mistakes when using carryover money as store rent, magnetic carts are distributed to customers, and customers who bring the card receive a 10% discount and parking is available. It would be a good idea to have them become members on the condition that they receive the following benefits.
