Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an electronic cash register (hereinafter referred to as
ECR), especially ECR that registers data on products whose selling prices are determined according to the weight of the product.

BACKGROUND ART For example, the selling price of products such as meat is determined according to the weight of the product. When registering data regarding such products in the ECR, the operator needs to key-in the sales weight and sales price. This type of key input operation is complicated and has the disadvantage that the registration process takes time.

Therefore, there is a method of registering a sales price corresponding to the sales weight with a product using a barcode, and then registering data regarding the product by reading the barcode with a scanner.

Problems to be Solved by the Invention By the way, when selling a product for which the unit price is set, such as 200 yen for 100g, for example, if a customer purchases 1kg of the product,
It is sometimes sold at a discount, such as 180 yen for 100g. In such a case, 1Kg would be 1800 yen, and the above-mentioned Sukiyana registration only records the selling price, so even though you sold 1Kg of the product, you ended up selling 900g of the product. Errors occur when managing the total sales weight. The same thing happens when a small amount of a product is purchased and sold at a premium.

Therefore, the main purpose of this invention is to accurately manage not only the selling price but also the sales weight, even when registering data related to a product whose selling price is determined according to the weight of the product. The aim is to provide an ECR that can be used.

Means for Solving the Problems In the present invention, a bar code is attached to a product whose selling price is determined according to the sales weight, and a sales price corresponding to the sales weight of the product. The ECR includes a barcode reading means for reading the barcode, a first storage means for storing the registration destination department number preset according to the type of barcode, and a first storage means corresponding to each of the plurality of department numbers. a second storage means for storing the total sales price and sales weight of the corresponding product; and a first storage means for determining the type of barcode read.
control means for reading out the department number of the registration destination according to the type of barcode from the storage means, and storing the total sales price and the total sales weight in the storage area of the second storage means corresponding to the department number; It consists of

Effect: In this invention, when a barcode attached to a product is read by the barcode reading means, the type of the barcode is determined, and registration according to the type of the barcode is stored in the first storage means. The previous department number is read out, and the sales price is stored cumulatively in the storage area of the second storage means corresponding to the department number, and the sales weight is stored cumulatively.
Therefore, not only the sales price but also the sales weight can be managed, so that even if the product is discounted when a large quantity is sold or a premium is added when a small quantity is sold, errors will not occur in the cumulative sales weight.

The storage area 113 stores a number flag indicating that the numeric keypad 43 has been operated and a flag F1 indicating that the x key 431 has been operated. The storage area 114 is used as a work register for temporarily storing data necessary for the CPU 7 to perform calculations.

Next, the barcode used in one embodiment of the present invention will be briefly explained. There are two types of barcodes: so-called source marking, where the product manufacturer prints the barcode on the product's packaging in advance, and so-called in-store marking, where each store affixes a label with the barcode recorded on the product's packaging. . In one embodiment of the invention, this in-store marking is used.

The barcode also includes UPC TYPE and
There is EAN13. _{UPC TYPE is represented by 2X 1 X 2 X 3 _ _ _ _ _} It is expressed as ₄ P ₅ C. And, X ₁ to X ₅ of UPC TYPE and X ₁ to X ₄ of EAN13 represent sales weight, and P ₁ to P ₄ of UPC TYPE and
P ₁ to P ₅ of EAN13 indicate amount data. Note that C/P is a check digit for amount data, and C is a check digit for the entire barcode.

FIG. 1 is a flow diagram for explaining the operation of an embodiment of the present invention.

Next, the specific operation of one embodiment of the present invention will be described with reference to FIGS. 1 to 5B.

First, registration destination department number areas 100, 101...
The registration destination department number is set in 109. That is,
The operator operates the mode changeover switch 41 to select a preset mode. Then, the user inputs a number representing the type of each barcode using the numeric keypad 43. In other words, the barcode type is UPC
Enter "0" for TYPE, "1" for EAN13 flag 21, "2" for EAN13 flag 22, and "9" for EAN13 flag 29. Then, the user operates the x key 431 to specify that the numerical data inputted from the numeric keypad 43 is the type of barcode. Thereafter, the operator inputs the department number using the numeric keypad 43, and operates the x key 431 again to specify that the numerical data is the department number. In this way, when entering the barcode type and department number and setting the next registration destination department number, press the subtotal key 4.
Operate 41. After setting all the registration destination department numbers, the cash/deposit key 442 is operated.

In this way, when the registration destination department number is entered by key, the CPU 7 stores the input registration destination department number in the registration destination department number storage areas 100, 101...109.
Set to . In other words, CPU 7 uses numeric keypad 4
When the numerical data representing the type of barcode is input from step 3, step (abbreviated as S in the illustration)
In step S1, it is determined whether numeric data has been input from the numeric keypad, and if so, the input numeric data is stored in the numeric buffer 111 in step S2. When the x key 431 is operated to identify that the numerical data entered from the numeric keypad 43 is a type of barcode,
The CPU 7 determines whether or not the x key 431 has been operated in step S3, and if so, transfers the numerical data stored in the numeric buffer 111 to the numeric buffer 112 in step S4.

In step S5, the CPU 7 determines whether the mode changeover switch 41 has been switched and the program mode has been selected. Once it determines that program mode is selected, the
In S6, it is determined whether numeric data has been input from the numeric keypad 43 or not. If numerical data has been input, the input numerical data is stored in the numeric buffer 111 in step S7. Then, in order to specify that the numerical data inputted from the numeric keypad 43 is a department number, the x key 43 is pressed.
1 is operated, it is determined in step S8 whether or not the x key 431 has been operated. If it has been operated, the numeric data stored in the numeric buffer 111 is used as the department number and the numeric data stored in the numeric buffer 111 is transferred to the numeric buffer 11.
Transfer to 2. Therefore, the position buffer 112
Numerical data representing the type of barcode and numerical data representing the department number are stored in .

When the subtotal key 441 is operated, the CPU 7
In step S10, it is determined whether or not the subtotal key 441 has been operated. When it is determined that the subtotal key 441 has been operated, it is determined in step S13 whether or not the number flag is set.
This is because when the numeric keypad 43 is operated, the numeric flag is set in the storage area 113.
The CPU 7 makes a determination based on whether or not the numeric flag is set in the storage area 113. If the numeric flag is not set, handle an error. Further, the CPU 7 determines whether or not the flag F1 is set in the storage area 113. This flag F1 is set when the x key 431 is operated. If the flag F1 is set, it is determined in step S15 whether the number representing the type of barcode stored in the numeric buffer 112 is 0 or not. If it is 0, it is a UPC TYPE barcode, so the department number stored in the numeric buffer 112 is transferred to the registration destination department storage area 100.

If the buffer 11 is set in step S15,
If the content of 2 is not 0, it is determined in step S17 whether the number representing the type of barcode stored in the numeric buffer 112 is ``1''. If "1" is stored, in step S18, the department number stored in the numeric buffer 112 is transferred to the registration destination department storage area 10.
Transfer to 1. Thereafter, in the same manner, the department numbers input sequentially up to the registration destination department number storage area 109 are set based on the number representing the type of barcode stored in the number buffer 112.
After completing the setting of the department number in the registration destination department number storage area 109, the CPU 7 supplies the data set in the registration destination department number storage areas 100, 101, . . . 109 to the printer 6 to print it. Finally, when the operator operates the cash/deposit key 442, the CPU 7 determines in step S11 whether or not the cash/deposit key 442 has been operated, and when it determines that it has been operated, in step S12, The words "end print" are printed by the printer 6.

Next, the operation in registration mode will be explained. In the registration mode, the operator switches the mode changeover switch 41 to set the registration mode, and causes the scanner 2 to read the barcode attached to the product purchased by the customer.

After performing the above-mentioned steps S1 to S5, the CPU 7 determines whether or not the registration mode is set in step S22. If the CPU 7 is in the registration mode, the CPU 7 determines whether the registration is by the scanner 2 or not in step S23. Determine whether or not. If it is determined that the registration is by scanner 2, it is determined in step S24 whether or not the read barcode is of UPC TYPE. If it is a barcode of UPC TYPE, in step S25,
The department number stored in the registered department number storage area 100 is stored in the register 114. If it is not UPC TYPE, it is determined in step S26 whether or not it is an EAN13 flag 21 barcode. If EAN13 flag 21
If the barcode is, in step S27,
The department number stored in the registered department number storage area 101 is stored in the register 114. In this way, the department number stored in the corresponding registration destination department number storage area is stored in the register 114 depending on the type of barcode.

The CPU 7 registers the register 114 in step S30.
The department number storage area 90 is searched based on the department number stored in . And step S31
At , the amount data represented by the barcode is displayed on the display 5. Furthermore, in step S32, the CPU 7 reads out the name of the corresponding department, and
The name, amount data, and department number are printed by the printer 6. Furthermore, in step S33, the amount data of the totalizer of the corresponding department number is cumulatively added. Furthermore, CPU 7 uses step S34.
In step 1, it is determined whether the barcode represents sales weight or not. If the barcode represents the weight of sales, the sales weight indicated by the barcode is added to the multiplier in step S35; if the barcode does not represent the weight of sales, the barcode is added to the number buffer 112 in step S36.
The number data inputted from the numeric keypad 43 stored in is added to the multiplier, and the series of operations is completed.

Effects of the Invention As described above, according to the present invention, a barcode indicating sales weight and sales price is attached to a product, and the barcode is read to determine the type of the barcode. The department number of the registration destination according to the type of barcode is read from the first storage means, and the amount data is cumulatively stored in the storage area of the second storage means corresponding to the department number, and the sales weight is also stored. Since it is stored cumulatively, even if you sell a large quantity of a product and get a discount on the unit price per unit weight, or sell only a small amount of that product and charge a premium on the unit price per unit weight,
There will be no error in the total sales weight.
