Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic cash register (hereinafter referred to as ECR) having a feature of discount operation at the time of product registration.

When registering a product in the conventional ECRI, it is necessary to press the product department key and discount key each time each product is registered, and a discount rate different from the preset discount rate is used. In some cases, the discount rate must be entered each time each product is registered, making the registration operation complicated.

The purpose of the present invention is to simplify such conventional complicated operations, and the purpose of the present invention is to provide an ECR that does not require inputting discount rates or suppressing discount keys for each product category. do.

An embodiment of the present invention will be described below with reference to Drawing i. FIG. 1 is a perspective view showing the ECR of this embodiment, and FIG. 2 shows the panel surface of this ECR. In these figures, E
To operate the CR, use the key switch L for mode switching provided on the panel surface, the product section A key 2 for setting the product section yen from 1 to 20, the numeric keypad 8, the discount key 4m, the subtotal key 4b, and the total key 4c. This is done through the keyboard 6 that has.

During operation, calculated values such as registration information are shown on the display 6, and the registration information and calculation results are printed on the printer 7. 8th
The figure is a block diagram showing the configuration of an ECR, in which a central processing unit (hereinafter referred to as CPU) 8 is connected to a storage means consisting of a read-only memory (hereinafter referred to as ROM) 9 and a random access memory (hereinafter referred to as RAM) 10. . R
The OM 9 stores the arithmetic processing procedures of the CPU 8.

The RAM 10 stores the unit price of the product in each product department, the total amount indicating the total amount of sales, the number of transactions, etc. In addition to the department areas of product departments 1 to 20, keys input from the keyboard 6 are stored. A number register that temporarily holds the discount rate of the product, a discount rate preset area that stores the discount rate of the product in advance, a discount register that stores the discount rate at the time of registration, and a discount flag that is set when discounting the product registration FD1 The total amount of total sales. Storage areas such as a total area indicating the number of transactions and a counter area indicating the number of transactions are provided. Further, the aforementioned keyboard 6 is connected to the CPU 8 as an input device, and the aforementioned display 6 and printer 7 are connected as output devices.

Next, the operation of the ECH of the present invention will be explained with reference to a flowchart. Numbers indicated using leader lines in the flowchart indicate operation steps of the CPU 8. First, when presetting the discount rate, set key switch 1 to setting mode, and use numeric keypad 8 to select the desired discount rate (for example, 1
0%).

In the flowchart of FIG. 4, step 11 checks whether or not there is any key force, and if there is key force, it is determined in step 12 whether or not it is a numeric key. In this case, since the numeric key was pressed, in step 18, a numeric value processing is performed to store the data entered manually in the numeric register of RAM10, and the process returns to step 11ζ.

Next, when the discount key 4a of the keyboard 6 is pressed, it is determined in step 12 to step 14 whether or not the setting mode is set. In case B, since the mode is set, the process proceeds to step 16 to check whether the discount key has been pressed, and further, in step 16, the data in the number register is moved to the discount rate preset area. In this way, the desired discount rate is stored in the discount rate preset area of the RAM, and the preset operation is completed.

Next, when registering a product, the key switch 1 is switched to the registration mode, and when the product is not to be discounted, one of the product department keys 1 to 20 corresponding to the sold product is pressed. However, when discounting a product, if a preset discount rate is used, the discount key 4a is pressed; if a different discount rate is used, the desired discount rate is entered in step 12.18, and then the discount key 4a is pressed. do. With this ξ, Figure 6 (a
) is when no discount is applied, Figure 5 (b) is when a preset discount rate is used, and Figure 6 (c) is when another discount rate (20
%) is used.

When the discount key 4a is pressed in FIGS. 6(b) and 6(c), step 11.1! , 14, 17 and 18, the presence or absence of a set number is determined in step 19. As shown in FIG. 6(b), if the discount key 4a is pressed, it is determined in step 20 whether the content of the discount rate preset area is O, and if it is 0, error processing is performed in step 21. In the case of ξ, the friendly ζ discount rate (10%) is preset, so the contents of the discount rate preset area are stored in the discount register in the block 22. As shown in FIG. 6(c). If the discount key 4a is pressed after inputting the number, step 28
In step II4, the contents of the number register are stored as they are in the discount register, and then in step II4, the discount rate is printed by the printer 7. FIG. 6(a) shows f! when registering a product using a preset discount rate (10%). An example of a P character is shown. Next, in step 26, the discount flag FD is set, and the process returns to step 11. Next, the department of the product to be sold is input using the product department key 2. If you want to sell the sweater (unit price 9,800 yen) in product category 1, click on product category 1 and step 11.12
, 14.17.18 and step! The process jumps to step fl'l via step 6, and the state of the discount flag FD is checked. If the 0 discount flag Fo is set, it is necessary to register the discount, so in step 28, the product unit price and discount of the product department are A discount is calculated based on the discount rate stored in the register, and the actual selling price is calculated. If the discount flag FD is not set, it is a regular price sale, so the value in the unit price area of that product department becomes the sales price as is.

This selling price is displayed on the display 6 (step 29
), further printed by the printer 7 (step 80)
. FIG. 6(a) shows an example of this printing, in which the actual selling price after discount calculation is printed. Subsequently, in step 81, the total and counter areas for the product category are updated, and the single-layer product registration is completed. If the user wishes to continue registering products using the same discount rate, the corresponding product department key 2 is pressed. Then step 26
Similar processing is performed through steps 81 to 81, and the selling price after discount calculation is printed. FIG. 6(a) shows that the blouse (unit price: 12,000 yen) in product category 2 has been subsequently discounted and registered as a selling price of 10,800 yen. In this way, in subsequent registrations, as long as the same discount rate is used, product registration can be completed simply by pressing the product department key 2 one after another. When changing the discount rate, enter the desired discount rate using the numeric keypad 8 (steps 11 to 18), and then press the discount key 4a to store the discount rate in the discount register and print it out (steps 18 to 25). ), so you can use that discount rate from now on.

Next, to obtain the subtotal of the products registered so far, the subtotal key 4b is pressed. Then step 11.1!
, 14.17.1B, 1@ to jump to step 82 and set the discount flag FD to O. - Then step 88.8
4, the process proceeds to step 86, where the subtotal of the items registered so far is displayed on the display 6, and the amount due is printed on the printer 7 (step 86).

Also, to end the product registration, the total key 4c is pressed.

Then step 11.1! , 14.17.18. !
Set discount flag Fn to 0 in step @2 via IS.
shall be. Next, the process proceeds to step 87 via step 88, where the display 6 displays the total amount of products registered so far, and furthermore, the amount is printed by the printer (°step 88). #16 Figure (a) shows an example of printing when the subtotal key 4b and total key 4C are pressed after registering two items. Next, the total and counter areas of the total sales in RAM10 are updated, and the product registration is completed (step 89). Furthermore, Fig. 6(b).

(c) shows an example of what is printed by the printer during conventional discount registration, and Fig. 6 (b) shows discount registration for each product category. Fig. 6 (c) shows discount registration after subtotal calculation. It is something.

When registering the ECH discount of this application, the printing is shorter than these printing examples.

As described above in detail, the present invention uses the discount rate at the time of discount registration stored in the discount register from the discount rate preset area or the keyboard when calculating the discount for each product transaction. Therefore, if there is no need to change the discount rate, there is no need to set the discount rate in the discount register for each transaction. Therefore, the operation of product transactions at the time of discount is greatly simplified compared to the past, and the registration operation can be speeded up. Therefore, even when there are many customers and the system is crowded, the registration process can be performed quickly. Furthermore, since less printing is required compared to conventional discount registration, the printer's printing time is shortened, and receipts can be saved.
