DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 1 is a block diagram showing the configuration of the entire ECR. The CPU 1 has a calculation unit 1-1 and a control unit 1-2, and R
A central processing unit that controls the overall operation of this ECR according to various programs in the OM2, and an input unit 3, a display unit 4, a printing unit 5, and a drawer 6 are connected to the CPU 1 as peripheral devices thereof. Control their I / O operations. The input unit 3 instructs the four arithmetic operations in addition to the numeric key AK for entering the amount of goods on the keyboard, the department key BK for instructing the registration by department, the cash / deposit key CK for closing the registration of one transaction. + Key DK, -key E
In addition to K, x key FK, ÷ key GK,% key HK for instructing discount calculation, and = key IK for instructing to call out the calculation result, a mode switch MS is also provided. The mode switch MS displays the "RE depending on the switching position.
"G (register)", "OFF (power off)", "RE (return)", "PGM (setting)", "Z (settlement)", "X"
(Inspection) ”and“ CAL (computer) ”modes are switched. Here, the CAL mode is a mode peculiar to the present embodiment, and is a mode in which calculation processing different from normal registration processing is performed. Now, in the registration mode in which the mode switch MS is switched to the REG position, when sales data for each department is input from the input unit 3, the CPU 1 causes the display unit 4 to display and output the sales data, and the printing unit 5. Is printed out on the receipt / journal and the value of the department totalizer 7-1 in the RAM 7 is updated.

The RAM 7 has a department totalizer 7-1, an A register 7-2, a B register 7-3, a C register 7-4, a D register 7-5, and an E register 7-6. The device 7-1 stores the total sales for each department. The A register 7-2 is a register for storing the commodity price data input by the number entered at the time of registration by department. The B register 7-3 is a register in which the discount amount input by the numerical input is stored in the computer mode. In the computer mode, the C register 7-4 and the commodity price data in the A register 7-2 and B
This is a register in which the discount rate calculated based on the discount amount in the register 7-3 is stored. The D register 7-5 is a register that stores a value obtained by subtracting the discount amount in the B register 7-3 from the product amount data in the A register 7-2 in the registration mode. E register 7-6 is D register 7
It is a register that stores a value obtained by subtracting the discount amount in the B register 7-3 from the value of -5. The ST register 7-7 is a register that stores the subtotal amount for one transaction.

Next, the operation of this embodiment will be described with reference to FIGS. FIG. 2 is a flowchart showing an outline of the operation of the entire ECR which is started when the power is turned on.
First, the CPU 1 detects the switching state of the mode switch MS (steps A1 and A2). Here, when the mode is switched to another mode other than the registration mode (REG mode) and the computer mode (CAL mode), processing (for example, inspection processing and setting processing) according to the mode is performed.

When it is detected in step A1 that the mode is switched to the REG mode, the same operation as usual is performed. That is, when the commodity price data is entered as a unit for registration by department (step A4),
The input commodity price data is set in the A register 7-2 (step A5). Here, when the department key BK is operated (step A6), the department-specific registration processing is performed,
The contents of the departmental totalizer 7-1 and the contents of the ST register 7-7 are updated, and the registered contents are displayed and printed out. Then, the registration of one transaction is completed and cash /
When the deposit key CK is operated (step A8), finalizing processing is performed (step A9), and the drawer 6
And the transaction totalizer (not shown) is updated on the basis of the opening operation and the subtotal data in the ST register 7-7, and change calculation and the like are performed. Then, issue a receipt (Step A
10).

Before the registration of one transaction is closed, the operator switches the mode switch MS from the REG mode to the CAL mode when discounting (single product discount) for the product registered for each department this time. Then, step A2
Since it has been detected that the mode has been switched to the CAL mode, the processing shifts to computer processing (step A11). FIG. 3 is a flow chart showing this computer processing. This computer process is to perform a calculation process for calculating a discount rate based on the product amount data entered numerically in the REG mode and the discount amount entered numerically in the CAL mode.
In step B1, it is checked whether or not a predetermined key operation is performed according to a predetermined key operation procedure for instructing the calculation of the discount rate, and if it is not the key operation for instructing the calculation of the discount rate. , Other calculation processing (four arithmetic operations) is performed.

Now, after entering the numbers, the-key EK, the% key HK,
When the = key IK is sequentially operated, it is detected in step B1 that the calculation of the discount rate is instructed. Then
In step B3, the A register 7-
The commodity price data entered in the number 2 is called. Here, for example, as a case where the last registration by department is registered for the product “amount (1234 yen)” of the department 1 as shown in FIG. 5, and then this product is discounted to “1000 yen” as an example. The following is a description.

In this case, the merchandise amount of "1234 yen" is called from the A register 7-2, and the discount amount of "1000 yen" is input in the entered number in the CAL mode. Then, this discount amount is set in the B register 7-3 (step B
4). Thus, in the next step B5, the discount rate is obtained based on the values of the A register 7-2 and the B register 7-3. That is, a calculation of (-A + B) ÷ A × 100% is performed, and the calculation result is set in the C register 7-4 (step B6) and displayed and output (step B7). Now, as shown in FIG. 5, by the discount rate calculation processing, (−1234 + 1000) ÷ 1234 × 100% =
18.96272% is calculated and displayed and output.

When the discount rate is obtained in the CAL mode in this way, the mode is returned to the REG mode. Then, Figure 2
In step A13, it is detected that the mode has been returned to the REG mode, and the input of the single item discount is in a waiting state (step A1
4). Here, when the-key EK is operated after the% key HK as a key operation for instructing a normal single item discount, C
The discount rate in register 7-4 is called (step A
15). Then, while removing the sign of this discount rate,
The second decimal place is valid, and the third place and below are discarded (step A16). As a result, the discount rate "-18.96272%" obtained in the CAL mode is converted into "18.96%". Then, in the next step A17, the single item% -calculation is performed based on the discount rate in the C register 7-4, and the product amount in the A register 7-2 is added to the C register 7-4.
The discount amount is obtained by multiplying the discount rate within. In this case, 1234 × 18.96 = 233.966
The calculation of 4 is performed to obtain the discount amount. Then, in the next step A18, correction processing for this discount amount is performed.

FIG. 4 is a flow chart showing this discount amount correction processing. First, it is checked whether rounding or rounding has been set in advance as a rounding process for the discount amount (step C1). Here, if the rounding is set, the decimal point of the discount amount is rounded off (step C2), and if the rounding is set, the decimal point is rounded down (step C3). Therefore, as shown in FIG. 5, when the decimal point is rounded off to the discounted amount of 233.9664 yen, it becomes "234 yen", and when the decimal point is rounded down, it becomes "233 yen".

Next, the discount amount is subtracted from the product amount in the A register 7-2, and the result is set in the D register 7-5 (step C4). Now, when the rounding processing is performed, "1234-234 = 1000" is calculated, and the value of the D register 7-5 is "1000 yen".
However, if rounding down is performed, "1
234-233 = 1001 ”is performed, and the value of the D register 7-5 becomes“ 1001 yen ”. Next, in step C5, the discount amount in the C register 7-3 is subtracted from the value in the D register 7-5, and the subtraction result is set in the E register 7-6. If the value of is not "0" (step C6), the discount amount is corrected (step C7). That is, the discount amount is corrected only when the discount amount does not match the desired discount amount due to the rounded processing.

When rounding is performed to the nearest whole number, the value of the D register 7-5 obtained by subtracting the discount amount from the product amount becomes "1000 yen", and the discount amount "1000" in the C register 7-3. The value of the E register 7-6 becomes "0" because it coincides with "yen", and the discount amount correction process is not performed. On the other hand, when rounding down is performed, the value of the D register 7-5 obtained by subtracting the discount amount from the product amount is "1001".
It becomes "yen" and the discount amount "1000" in the C register 7-3.
The value of the E register 7-6 becomes "1" because it does not match the "circle". Therefore, in this case, the discount amount is corrected, the discount amount “233 yen” in the D register 7-5 is added with the value “1” of the E register 7-6, and the discount amount is “234”.
It is corrected to "Yen".

When such discount amount correction processing is completed, FIG.
In step A19, the correction registration is performed for the department totalizer 7-1 based on the discount amount in the D register 7-5, and the value of the ST register 7-7 is corrected. . In other words, correction registration is performed to subtract the total sales of the products of the department 1 from the department totalizer 7-1 with the discount amount "234 yen", and the discount amount "234 yen" is added to the ST register 7.
Perform a correction process that subtracts from the subtotal of -7. After performing such a correction process, the process returns to step A1.
The normal processing can be continued under the REG mode, the next divisional registration is performed, and the finalization processing for closing the registration of one transaction is performed.

As described above, in the present embodiment, even though the ECR has the single item discount function (single item%-), but does not have the single item discount function (single item-), the registration before terminating the registration of one transaction. On the way, REG mode to CAL
When you switch to the mode, the product amount data that was entered as a numerical value in the previous registration operation for each department is called. Therefore, calculate the discount rate based on this product amount data and the discount amount that you entered as a numerical value in the CAL mode. You can Then CA
When switching from L mode to REG mode again, CAL
A discount rate is calculated by using the discount rate calculated under the mode to obtain the discount amount, and the correction registration process can be performed based on the discount amount. In this case, even if the discount amount is rounded, the discount amount is corrected so that the discount amount and the discount amount match, so that it is possible to reduce the price of the individual item as desired.

In the above embodiment, the discount rate is calculated in the CAL mode and the discount rate is used to perform the single item discount calculation. However, the calculation in the CAL mode or the REG mode is performed. Needless to say, the calculation is not limited to this.

[0020]

According to the present invention, it is possible to switch to a computer mode that performs a calculation process different from the registration process for registering sales data, and use the result of the calculation process under the computer mode to register the mode. Since it is possible to register below, for example, even with an ECR that does not have a single item discount function, if a discount rate is calculated under the calculator mode and the discount rate is calculated using this discount rate under the registration mode, It is possible to register in the same way as a single item discount.
