BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sales data processing apparatus that performs discount processing or premium processing.

0002

2. Description of the Related Art Sales data processing devices such as electronic cash registers and POS registers sometimes perform discount processing or premium processing on sales data. Discount processing is carried out, for example, in supermarkets, etc., and is called a time service, in which the price of a product is discounted by a certain percentage only during a specific time period. On the other hand, the surcharge process is carried out, for example, in a restaurant, etc., and a late-night charge is set after 11 pm, and the price of the menu is increased by a certain percentage.

[0003] For example, when performing discount processing, sales data is input by product classification such as department and PLU, and the subtotal amount is obtained by operating the "subtotal" key. Next, input the discount percentage value and operate the "%-" key to specify discount processing. As a result, a discounted subtotal amount is calculated, and this subtotal amount is accumulated in the subtotal memory.

0004

[Problem to be Solved by the Invention] Therefore, in conventional sales data processing devices, although the subtotal amount after discount or premium is accumulated, the actual sales amount of sales data is not accumulated by product category, so it is difficult to register sales data. was inaccurate.

[0005] An object of the present invention is to enable the actual sales amount of sales data to be accumulated for each product category when discount processing or premium processing is performed on the subtotal amount.

[0006]

[Means for Solving the Problems] The means of the present invention are as follows. Storage means 1 (see the functional block diagram in FIG. 1,
(the same applies hereafter) determines the product category that can be discounted or increased based on the input sales data for each product category, and temporarily stores the sales data for each product category. The discount/surcharge amount calculation means 2 calculates the discount amount or premium amount for each product category based on the input discount or premium data and the sales data for each product category stored in the storage device 1. The determining means 3 determines the sales amount for each product category based on the discount amount or the premium amount calculated by the discount/surcharge amount calculation means 2. The sales data storage means 4 accumulates and stores sales data for each product category. The accumulating means 5 accumulates the sales amount for each product category determined by the determining means 3 in the sales data storage means 4.

[0007]

[Operation] The operation of the means of the present invention is as follows. Based on the input sales data for each product category, the storage means 1 determines the product category that can be discounted or increased, and temporarily stores it for each product category. Next, based on the input discount or premium data and the sales data for each product category in the storage device 1, the discount/surcharge amount calculation means 2 calculates the discount amount or premium amount for each product category. Based on this discount amount or premium amount, the determining means 3 determines the sales amount for each product category. The sales data storage means 4 accumulates and stores sales data for each product category. The sales amount determined by the determining means 3 is accumulated in the sales data storage means 4 by the accumulating means 5. Therefore, when discount processing or premium processing is performed on the subtotal amount, the actual sales amount of the sales data can be accumulated for each product category.

Next, the operation of this embodiment will be explained based on FIGS. 4 to 8. 4 and 5 are flowcharts showing operations in registration mode.

■Department Registration First, in step S1, a key operation is awaited. If there is a key operation, the process advances to step S2. In step S2, it is determined whether department registration has been designated by operating the "Department 1" to "Department 4" keys. Normally, after the price of the product is input using the numeric keypad, the "Part 1" to "Part 4" keys are operated. In step S2, in case of department registration, step S3
Otherwise, the process proceeds to step S6.

When the process proceeds to step S3 after department registration, it is determined whether or not the input department has a discount/surcharge target flag. In step S3, if the flag is "1", the process proceeds to step S4; otherwise, the process proceeds to step S5.

[0020] If the input department is subject to discount/surcharge, the process advances from step S3 to step S4. In step S4, sales data (department number and amount) are stored in the work area 14c. At this time, work area 1
The subtotal of the amount data stored in 4c is stored in the SIST memory.

In the following step S5, department totalizer processing is executed. That is, the total amount and number of items are stored in a predetermined area of the department file 14b corresponding to the input department. The registration process ends by executing step S5.

■ PLU registration PLU No. is entered by operating the numeric keys. “P” is entered after
When the "LU" key is operated, the answer in step S2 is NO and the process proceeds to step S6, where it is determined whether PLU registration is to be performed. If YES is determined in step S6, step S7
If NO, the process proceeds to step S10. In this case, since the "PLU" key has been operated, the determination is YES and the process proceeds to step S7.

In step S7, the input PLUNo.
It is determined whether or not there is a discount/surcharge target flag. In step S7, if the flag is "1", step S7
If not, proceed to step S9.

[0024] Input PLUNo. If there is a flag in step S8, the sales data (PLUNo.
and the amount) are stored in the work area 14c. In the following step S9, sales data is registered in the PLU file 14a. That is, the input PLUNo. The total amount and number of items are stored in a predetermined area of the PLU file 14a corresponding to . The registration process ends by executing step S9.

(2) Discount/price increase registration (+/- registration) When the "-" key or the "+" key is operated, discount/price increase registration is performed. Typically, discount/increase registration is performed after department registration or PLU registration is entered. In this case, NO is determined in each of steps S2 and S6, and the process proceeds to step S10.

In step S10, it is determined whether discount/increase registration is to be performed. If YES is determined in step S10, the process proceeds to step S11; if NO, step S1
Proceed to step 8. In this case, since the "-" key or the "+" key has been operated, the answer is YES and the process proceeds to step S11. In step S11, it is determined whether or not the flagged product has just been registered, that is, after the product for which the discount/surcharge target flag has been set has been input. If YES in step S11, the process advances to step S12, and if NO, the process advances to step S15.

If the flagged product has just been registered, the process advances to step S12, where the discount/surcharge amount is added to the discount/surcharge amount area corresponding to the input department or PLU. In the subsequent step S13, the discount/surcharge amount is subtracted from or added to the contents of the item amount area corresponding to the input department or PLU. Next, in step S14, the contents of the item amount area are set to the subtotal (ST).
Cumulatively stored in memory. The registration process ends by executing step S14.

Further, if the determination in step S11 is NO, the process advances to step S15. In step S15, “S
Based on the presence or absence of the "post-IST flag", it is determined whether or not the "SIST" key has been input. If YES in step S15, proceed to step S16; if NO, proceed to step S1
Proceed to step 4.

If discount/price increase registration is specified after inputting the "SIST" key, error handling in step S16 is executed, and the "post-SIST flag" is cleared in step S17, ending the registration process. Also, in step S15, N
In the case of O, the process advances to step S14.

■Discount/Premium Registration (%±Registration) When the ``%-'' key or the ``%+'' key is operated, discount/premium registration is performed. Typically, discount/surcharge registration occurs after department registration or PLU registration is entered, or after the "SIST" key is entered. In this case, steps S2, 6, 10
If the answer is NO in each case, the process proceeds to step S18.

[0031] In step S18, it is determined whether discount/surcharge registration is required. If YES in step S18, the process advances to step S19, and if NO, the process advances to step S32. In this case, since the "%-" key or the "%+" key was operated, YES is determined and the process advances to step S19.

In step S19, it is determined whether or not a flagged product has just been registered, that is, a product for which a discount/surcharge target flag has been set has been registered. Step S19
If the answer is YES, the process proceeds to step S20, and if the answer is NO, the process proceeds to step S24.

If the flagged product has just been registered, the process advances to step S20. In step S20, a discount calculation or a premium calculation is performed on the amount of the product, and the discount/surcharge amount and the actual sales amount are determined. In the following step S21, the discount/surcharge amount determined in step S20 is added to the discount/surcharge amount area corresponding to the registered product. Furthermore, in step S22, the actual sales amount is also subtracted or added to the item amount area corresponding to the registered product. In step S23, the contents of the subtotal (ST) memory are subtracted or added based on the discount/surcharge amount. The registration process ends by executing step S23.

If it is determined in step S19 that the flagged product has not just been registered, the process advances to step S24. In step S24, the "SI
It is determined whether or not the "ST" key has been input. Step S2
If YES in step 4, the process advances to step S25, and if NO, the registration process ends after error processing in step S31.

If the "SIST" key has been input, the process advances to step S25. In step S25, a discount calculation or a premium calculation is performed on the contents of the subtotal (ST) memory,
The discount/surcharge amount and the actual sales amount of the ST memory are determined. In the following step S26, a discount calculation or a premium calculation is performed on the price data of the target product stored in the work area 14c, and the respective discount/surcharge prices are determined.

In step S27, the discount/surcharge amount is added to the discount/surcharge amount area of the PLU file 14a or department file 14b corresponding to the target product stored in the work area 14c.

In step S28, work area 1
PLU corresponding to the discount/surcharge target product stored in 4c
The discount/surcharge amount is subtracted from or added to the item amount area of the file 14a or department file 14b, respectively.

In step S29, the work area 14c is cleared, and in the next step S30, the "post-SIST flag" is cleared, and the registration process ends.

■ Input of "SIST" Key When the "SIST" key is input, NO is determined in each of steps S2, 6, 10, and 18, and the process advances to step S32. Step S
In step S32, it is determined whether or not the "SIST" key has been input, and the answer is YES, and the process proceeds to step S33. Step S
In step S33, "1" is written in the "post-SIST flag" of the RAM 14, and in the following step S34, the contents of the SIST memory are displayed. The registration process ends by executing step S34.

It should be noted that if the other key is YES in step S32, the process advances to step S35, and other key processing is executed.

Next, the operation when the following key operations are performed will be described.
