Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to electronic cash registers (hereinafter referred to as electronic cash registers).
(hereinafter referred to as ECR), and in particular relates to ECR that automatically rounds down fractions of the total amount of registration entered during registration processing.

Description of Prior Art Conventionally, some supermarkets and the like have rounded down the fractional amount of the registered price of a product. In this way, rounding down the registered amount of a product not only provides a service to the customer, but also has the advantage that the ECR operator can easily enter the last part of the registered amount, thereby increasing the processing speed. However, conventionally, at the above-mentioned stores, regardless of how much the customer has purchased at one time or how much the customer has purchased at the store to date,
Fractions were rounded down uniformly for all customers. As a result, although the ECR operator's processing speed could be increased, the effect of attracting customers to the store was rather small. In other words, if the more things a customer buys at a store, the larger the cut-off amount will be, the customer will be willing to go to that store.

If a system were to be adopted in which the cut-off amount for each customer would be different depending on the cumulative total of registered amounts to date, the calculation would have to be done by the operator, which would place an excessive burden on the operator and the processing The speed becomes noticeably slower. Therefore, it would be extremely useful to have an ECR that could perform such calculations and automatically perform truncation.

Purpose of the Invention Therefore, the main purpose of this invention is to automatically round down fractions of the total registration amount and process the registration.
Moreover, the purpose is to provide an ECR in which the amount rounded down to the nearest whole number can be increased or decreased according to the cumulative registration amount of the customer.

Structure and Effects of the Invention To summarize, the present invention provides a first method that stores in advance the limit amount of fractions that can be rounded down according to the cumulative purchase amount.
A storage means is provided, and when a customer's past cumulative registration amount is input from the cumulative registration amount input means, a rounding limit amount corresponding to the cumulative registration amount is read out from the first storage means. Ru. Then, based on the read rounding limit amount, calculate the rounding down of the current registered total amount input from the registered amount inputting means and stored in the second storage means, and rounding down the calculated fractional amount. The registration process is performed by subtracting the amount from the current registration total amount.

According to this invention, when a customer's past cumulative registration amount is input, the fractional amount of the total registration amount is automatically calculated and registered, so that an excessive burden is not placed on the operator. In addition, the fractional amount of the current registration total is calculated according to the size of the cumulative registration amount input, and the registration process is performed by subtracting the calculated rounding amount from the total registration amount. Since services can be provided to each customer in accordance with the accumulated past registration amount, the effect of attracting customers to the store can be increased.

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

DESCRIPTION OF EMBODIMENTS FIG. 1 is an external perspective view of an ECR according to an embodiment of the present invention. In the figure, on the front of this ECR 1 is a printer 2 for printing receipts etc.
and a display 3 are provided. Further, a keyboard 4 is provided on the front surface of the ECR 1 so as to project forward.

FIG. 2 is a key arrangement diagram of the keyboard 4 shown in FIG. 1. In the figure, the keyboard 4 includes
A mode key 41 for switching the operation mode of the ECR 1, a department key 42 for inputting the department code of each product, and a numeric keypad 43 for inputting numerical information are provided. In addition, keyboard 4
A total key 44 is provided. This total key 44 is a key for instructing rounding down of fractions, and is operated at the end of one transaction.

FIG. 3 is a schematic block diagram of ECR1. In the figure, the aforementioned printer 2, display 3, and keyboard 4 are connected to the CPU 5. Also,
A ROM 6 and a RAM 7 are connected to the CPU 5. The ROM 6 stores operating programs for the CPU 5. RAM7 has areas 71 to 7 as shown in the diagram.
Contains 4. Area 71 is used as a cumulative purchase area for storing the cumulative purchase amount. Area 72 is used as a registration total area for storing the total registration amount. Area 73 is
It is used as a rounded-off amount area for storing the rounded-off amount calculated by the CPU 5. Area 74 is used to store a rounded-down amount calculation table as shown in FIG.

FIG. 4 is a diagram schematically showing the storage area of the rounded-down amount calculation table stored in the RAM 7 shown in FIG. In the figure, this rounded-off amount calculation table 74 stores the rounded-off limit amount for each cumulative purchase amount. For example, if the cumulative purchase amount is from 0 yen to 10,000 yen, the rounding down limit is 0, and no rounding is performed.
If the cumulative purchase amount is between 10,000 yen and 50,000 yen, the limit for rounding down to the nearest whole number is 4 yen. At this time, if the last part of the registered total amount is less than 4 yen, it will be rounded down. Further, at this time, if the end of the registered total amount is between 6 yen and 9 yen, the end is subtracted and becomes 5 yen. Additionally, if the cumulative purchase amount is between 50,001 yen and 100,000 yen, the maximum amount will be rounded down to 9 yen.
In this case, if the end of the registered total amount is between 1 yen and 9 yen, the end of the registered total amount is truncated to 0 yen. Hereinafter, the limit amount is stored with the fractions rounded down for the same purpose. In addition, in this rounding-off limit calculation table 74, the rounding-off limit is not stored for the cumulative purchase amount exceeding 1 million yen, but in this case, the rounding-off limit may be unified to 99 yen. Furthermore, the rounding down limit may be stored differently for each stage of the cumulative purchase amount.

FIG. 5 and FIG. 6 are diagrams showing examples of receipts printed by the printer 2, and in particular,
FIG. 5 shows an example of receipt printing when fractions are not rounded down, and FIG. 6 shows an example of receipt printing when fractions are rounded down. FIG. 7 is a flowchart for explaining the operation of ECR1. Below, this figure 5 to 7
The operation of the above embodiment will be explained with reference to the drawings.

First, as shown in step S1 in FIG. 7, the operator inputs the cumulative purchase amount up to the previous time.
As will be described later, at the bottom of the receipt issued to the customer at the end of one transaction, the total amount of purchases to date, including the transaction at that time, is printed.
The customer takes this receipt with him the next time he buys a product. The operator then inputs the cumulative purchase amount printed on the receipt into the ECR1. Next, as shown in step S2, the CPU5
stores the entered cumulative purchase amount in the cumulative purchase area 71 of the RAM 7. Then the CPU
Step 5 displays the cumulative purchase amount on the display 3 in step S3, and prints the cumulative purchase amount on the receipt by the printer 2 in step S4 (see the printed content on the second line from the top in Figures 5 and 6). )
let Next, the operator inputs data for product registration, and the CPU 5 accordingly performs registration processing in step S5. And CPU5 is
The registered total amount at that time is displayed on the display 3 in step S6, and printed on the receipt by the printer 2 in step S7. Next, the operator presses the total key 4 as shown in step S8.
Turn on 4. Accordingly, CPU5 executes step S9
As shown in , the registered total amount of the current transaction is added to the cumulative purchase amount of previous transactions stored in the cumulative purchase area. And step S10
In the step, the CPU 5 determines whether there is a fraction in the total amount of registration. As shown in Figure 4, in this example, the maximum amount for rounding off fractions is 99 yen, so whether there is a fraction in the total registered amount is determined by whether there is a fraction in the lower two digits of the total registered amount. It is determined whether or not. If it is determined that there is a fraction in the total registered amount, the CPU 5 proceeds to step S11 and calculates the amount that can be rounded down. Specifically, it is searched to which rank of the rounded-down amount calculation table 74 the cumulative purchase amount stored in the cumulative purchase area 71 belongs, and the rounded-down limit amount corresponding to that rank is read out. Then, the amount that can be rounded down to the fraction of the registered total amount is calculated based on the read fractional amount limit.
Subsequently, the CPU 5 stores the calculated rounded-down amount described above in the rounded-down amount area 73 of the RAM 7, as shown in step S12. And CPU5
The process proceeds to step S13, where it is determined whether fractions can be rounded down. As shown in FIG. 4, if the cumulative purchase amount is between 0 yen and 10,000 yen, the limit for rounding down fractions is 0 yen. Therefore, since it is not possible to round down the fraction at this time, it is determined that rounding is not possible, and the process proceeds to step S18, which will be described later. On the other hand, if it is determined that fractions can be rounded down, the CPU 5 proceeds to step S14, and calculates the total purchase amount stored in the cumulative purchase amount area 71 by rounding it down to the fractional amount area 71.
Subtract the rounded-off amount stored in 3. Further, in step S15, the CPU 5 subtracts the rounded-off amount stored in the rounded-down amount area 73 from the registered total amount stored in the registered total area 72. Subsequently, the CPU 5 causes the display 3 to display the new registered total amount after rounding down the fractions, and causes the printer 2 to print it on the receipt in step S17. after that,
In step S18, the CPU 5 cuts a groove (see FIGS. 5 and 6) in a predetermined portion of the receipt. This kerf makes it easy to insert two receipts.
It can be divided into two parts. Note that perforations or the like may be provided instead of such cut grooves. Next, the CPU 5 causes the printer 2 to print the new cumulative purchase amount stored in the cumulative purchase amount area, rounded down, on the receipt. This printing position is as shown in Figures 5 and 6.
It is at the bottom of the receipt. The customer cuts off the part on which the cumulative purchase amount is printed and hands it to the operator when registering the next purchase. The above steps
As explained in S1, the operator looks at this cumulative purchase amount and inputs it into ECR1. Next, the CPU
Step 5 proceeds to step S20 and clears all of the cumulative purchase amount area 71, registered total amount area 72, and rounded-down amount area 73.

Incidentally, if it is determined in step S10 that there is no fraction in the total registered amount, the processing of rounding down the fraction is not performed and the operations from step S18 onwards are directly performed.
