DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise sales data processing apparatus such as an electronic cash register having ordinary merchandise registration, merchandise discount registration, and collective discount registration.

[0002]

2. Description of the Related Art In general, in a product sales data processing apparatus, for example, an electronic cash register, sales data such as a department code and quantity of a sold product are inputted using a keyboard or the like, and a sales amount obtained as a result of the processing is input. And output the product data to a printer or a display unit to register the product. The sales amount is added to the totalizer one by one, and the payment amount corresponding to the total amount is processed to complete the closing registration. Further, in the conventional product sales data processing device, the following discount registration is added in order to promote sales. That is, for a special sale product, a product discount rate is set in advance for each product, and when the special sale product is sold, product discount registration that discounts the sales amount based on the product discount rate is enabled. In addition, even if a product other than a bargain product is purchased, a batch discount registration that discounts the sales amount based on a fixed ratio of a batch discount rate regardless of the purchased product is enabled. Since the collective discount registration does not require a product discount rate to be set for each product,
This is convenient for bargain sales at the end of the term or special offers for members. If the special sale product is further discounted collectively, the calculation of the sales amount becomes complicated and there is a possibility that the service will be over-serviced. Therefore, the special sale product is excluded from the collective discount registration.

[0003]

As described above, in the conventional merchandise sales data processing apparatus, merchandise discount registration is executed with higher priority than collective discount registration. Therefore, if the commodity discount rate is set higher than the collective discount rate, the customer does not have any problem because the discount price of the bargain product is larger than other products. However, if the collective discount rate is set higher than the product discount rate, the customer becomes dissatisfied because the discount price of the bargain product is smaller than other products. Therefore, for example, before opening a store such as a bargain sale at the end of the term or a preferential member sale, the manager may raise the product discount rate of the special sale product to a value higher than the collective discount rate or change the setting to delete the product discount rate. Therefore, it was necessary to eliminate customer dissatisfaction. The present invention has been made in order to solve such a problem, and it is possible to surely and promptly guarantee a customer a discount of a collective discount rate or more without changing the discount rate of a special sale product one by one. It is intended to provide a sales data processing device.

SUMMARY OF THE INVENTION According to the present invention, a commodity discount rate is set for a commodity for which a commodity discount rate is set based on the commodity discount rate. In general, the product registration is performed in the product sales data processing device which performs the product registration and performs the collective discount registration for discounting the sales amount based on the set collective discount rate when the collective discount declaration is made. When the product discount rate is set, the product discount rate is compared with the collective discount rate, and if the product discount rate is lower than the collective discount rate, the product discount registration is performed. And a control means for performing the collective discount registration.

[0005]

According to the present invention having such a configuration, for a product for which a product discount rate has been set when the collective discount is declared, the product discount rate is compared with the collective discount rate to determine the product. If the discount rate is lower than the collective discount rate, collective discount registration is performed instead of product discount registration, so that customers can be surely and promptly guaranteed a discount that is higher than the collective discount rate regardless of the purchased product. Becomes possible.

An I / O port 18 for outputting a drive signal to a printer drive circuit 15 for controlling a printer 14 for performing the above operation and a drawer opening device 17 for opening a drawer 16 for storing cash and the like are controlled. Here CPU1
The program data necessary to control each part is RO
M3 and the variable data are stored in the RAM 4, respectively.

As shown in FIG. 2, the keyboard 10 has a numeric key 21 for counting the quantity of each product for sale, a deposit amount from a customer, etc., and a department code (1 to 1) for identifying each product for sale. 15) a department key 22 for inputting a total number, a subtotal key 23 for displaying or printing the total amount, a deposit / current total key 24 for instructing closing of registration, a multiplication key 25 for inputting a quantity, A clear key 26 used for releasing an error state, a collective key 27 for declaring a collective discount, and the like are arranged.

FIG. 3 is a diagram showing a main memory configuration of the RAM 4 related to the present invention. In the figure, a department table 31 for setting and storing a product name, a unit price and a product discount rate for each department code (1 to 15), a product totalizer 32 for adding a sales price of a registered product, and a sales price irrespective of a purchased product. Discount rate 33 for setting and storing a ratio for collectively discounting, a collective totalizer 34 for adding the discounted sales amount of the products registered for the batch discount, and a sales amount based on the product discount rate in the department table 31. A discount totalizer 35 for adding the sales amount after the discount, a registration data memory 36 for storing registration data, and the like are set. The product name, unit price, product discount rate, and the like in the collective discount rate 33 and the section table 31 are set by operating the various keys of the keyboard 10 with the mode switch 6 in the “setting” mode before the store opens, for example. It is something to memorize.

The CPU 1 performs a predetermined initialization process in response to power-on, and waits for key data to be input from the keyboard 10. Then, when the key data is input, the business mode selected by the mode switch 6 is determined, and key processing corresponding to each business mode is executed. Here, when the key data of the section key 22 is input from the keyboard 10 while the “registration” mode is selected, the registration processing shown in the flowchart of FIG. 4 is executed. First, in ST (step) 1, sales data is registered. That is, product data such as a product name, a unit price, and a product discount rate corresponding to the department code of the department table 31 that matches the input department key 22 is extracted and input by a combination input of the numeric key 21 and the multiplication key 25. The sales amount and the product data obtained by multiplying the calculated quantity by the unit price are stored in the registration data memory 36. At this time, the product data and the quantity are also output to the display unit 12. The process of ST1 is repeated for all the products purchased by the customer.

Next, when the subtotal key 23 or the collective key 27 is input from the keyboard 10, the end of the sales data is determined in ST2 and the process of ST3 is started. In ST3, one piece of registration data stored in the registration data memory 36 is extracted, and if there is registration data, it is determined whether or not a commodity discount rate is set in ST4.

As a result, if the commodity discount rate has not been set, it is determined in ST5 whether or not the collective key 27 has been input. However, if the batch key 27 is input, S
Batch discount registration is performed at T6. That is, the sales amount is multiplied by the collective discount rate 33 and the discounted sales amount is added to the collective totalizer 34. At the same time, the printer 14 prints the product data and the discounted sales amount on the receipt.

As a result of the discrimination in ST5, if the subtotal key 23 is inputted without the collective key 27 being inputted, the merchandise is registered in ST7. That is, the sales amount is added to the product totalizer 32, and the product data and the sales amount are printed on the receipt by the printer 14.

If it is determined in step ST4 that the commodity discount rate has been set, it is determined in step ST8 whether the collective key 27 has been input. However, if the subtotal key 23 is input without inputting the batch key 27, the merchandise discount is registered in ST10. That is, the discounted sales amount obtained by multiplying the sales amount by the product discount rate and adding the discount is added to the discount totalizer 35. At the same time, the printer 14 prints the product data and the discounted sales amount on the receipt.

As a result of the determination in ST8, when the collective key 27 is input, the commodity discount rate is compared with the collective discount rate 33 in ST9 which is the control means, and when the commodity discount rate is lower than the collective discount rate 33, At step ST6. If the commodity discount rate is not lower than the collective discount rate 33, the commodity discount is registered in ST10.

As described above, the registration data memory 36
The registration data stored in the database is extracted one by one, and the processing is branched into the product registration in ST7, the collective discount registration in ST6, and the product discount registration in ST10. When the registration data is completed in ST3, the sales amounts added to the product totalizer 32, the collective discount totalizer 34, and the discount totalizer 35 are totaled in ST11, and the total amount obtained by adding the tax amount of a certain ratio is displayed on the display unit 12. It is displayed and printed on the receipt by the printer 14.

Thereafter, in ST12, the deposit / current total key 2
If "4" has been entered, closing registration is performed in ST13. That is, the difference between the deposit amount and the total amount entered by the number key 21 immediately before, that is, the change amount, is calculated and displayed on the display 12, the receipt is issued from the printer 14, and the money is exchanged with the customer. Drawer 1 for
Release 6. If any other key is entered, S
Other processing is performed in T14, but is not directly related to the present invention, and thus detailed description is omitted.

In a store employing the merchandise sales data processing apparatus of this embodiment configured as described above, for example, before opening a bargain sale at the end of a term or a member special treatment sale, the manager sets the collective discount rate 33 to a predetermined ratio. Just set it. When the clerk inputs the department code and quantity of the sold product, the registration data is sequentially stored in the registration data memory 36,
When the collective key 27 is operated, the product discount rate is automatically compared with the collective discount rate 33 for the special sale product. As a result, if the product discount rate is lower than the collective discount rate 33, the product discount Batch discount registration is performed instead of registration.
Therefore, it is possible to reliably and promptly guarantee the customer a discount that is equal to or higher than the collective discount rate regardless of the purchased product.

In the above embodiment, the collective discount rate and the product discount rate are set and stored in the RAM 4 in advance.
It may be input each time by the key on 0. In this embodiment, the end of the sales data is determined by the subtotal key 23 and the collective key 27. However, the subtotal key 23 can be excluded and only the collective key 27 can be used. Further, in this embodiment, the registered data stored in the registered data memory 36 is processed without processing, but may be processed after being classified (sorted) or merged. Further, in the present embodiment, the sales amount is directly discounted based on the product discount rate and the lump-sum discount rate. However, by issuing a coupon or service ticket of the same amount as the discount amount, the sales amount is reduced indirectly. It is also possible. Of course, various modifications can be made without departing from the spirit of the present invention.

[0019]

As described above, according to the present invention,
Regardless of the purchased product, a product sales data processing device that can surely and promptly guarantee a discount that is equal to or higher than the collective discount rate can improve work efficiency, improve service to customers, and increase store credibility. it can.
