Description

[Detailed Description of the Invention] Industrial Field of Application This invention is applicable to electronic cash registers (hereinafter referred to as ECR).
In particular, it relates to ECR in which a product code is set as a barcode on a product, and data related to the product is registered by reading the barcode and using a so-called price lookup (PLU) function.

BACKGROUND ART Conventionally, there are two types of ECRs that register data related to products based on PLUIfi functions.

One of them is to pre-PL the Shinwei data for each product.
In this method, the product code is registered in the U file, the operator manually enters the product code, and the *ri data corresponding to the product code is read out from the PLU file and registered. The other method is to set the product code as a barcode on the product in advance, read that barcode with a scanner, read the unit price data corresponding to the product code included in the read barcode from the PLU file, and register it. This is the so-called scan method.

Problems to be Solved by the Invention Incidentally, in supermarkets and the like, in order to sell multiple products as a whole, there are cases where a selling price (package price) is determined for the multiple products.For example, a 4flA product For example, a product is sold for 300 yen.Sometimes these products are sold as a set of 4, and sometimes they are sold individually for 75 yen.However, if a scanning method is used, At this store, the package price of 300 yen for 411 meters is recorded on each product using a barcode, so if a customer purchases only one item, the operator will record the price data for that item each time. Quantity data and the key must be done manually,
The advantage of the scanning method, which records barcodes on products and speeds up processing, is diminished.

Therefore, the main purpose of this invention is to sell multiple products as a unit, even if the package price of the multiple products is determined and a customer purchases one of the products. To provide an ECR that can register data related to a product without requiring an operator to manually collect price data.

Means for Solving the Problems This invention preliminarily stores sales price data for each product package and package number data representing the quantity of packaged products in barcodes, in order to eliminate the need for operators to input price data.・Set it. And E
The CR includes a barcode reading means for reading barcodes, a quantity inputting means for inputting the quantity of products purchased by the customer, and package sales price data, package quantity data and quantity input represented by the read barcode. and registration means for calculating the selling price of each individual product based on the quantity of the product inputted from the means and registering data regarding the product based on the calculation result.

In this invention, when the barcode set on the product is read by the barcode reading means and the quantity data of the product purchased by the customer is input from the number M input means, the package sales price data included in the barcode is read. is divided by the package number data and multiplied by the input quantity data to calculate the selling price of each product, and the calculation result is registered. Therefore, the operator only needs to read the barcode using the barcode reading means and input the quantity from the quantity inputting means, thereby making it unnecessary to input price data and speeding up the process.

Actual tIA Example FIG. 2 is an external view of one embodiment of the present invention, and FIG. 3 is a key arrangement diagram of a keyboard included in the ECR shown in FIG.

First, referring to FIG. 2, a scanner 2 is connected to an ECR main body 1 via a cable 3. As shown in FIG. The scanner 2 constitutes barcode reading means for reading barcodes recorded on or attached to products.

The ECR body 1 is provided with a keyboard 4 on its horizontal operation surface, and a display 5 and a printer 6 on its vertical operation surface.

As shown in FIG. 3, the keyboard 4 is provided with a mode changeover switch 41, a department key 42, a numeric keypad 43, and a function key 44. Mode changeover switch 41
is program mode (P).

Power off (OFF), registration mode (R), 2 inspection mode (X
) and payment mode (Z). The department key 42 specifies the department code of the product to be registered. The numeric keypad 43 is used to input data such as the number of products purchased by the customer. The function keys 44 are operated to give various calculation commands, and are composed of a subtotal key 441 and a cash/deposit key 442. The subtotal key 441 instructs the calculation of the total data of the products registered so far, and the cash/deposit key 442 instructs the calculation of the total data of all the products purchased by the customer, and also commands the calculation of change. It is something to do.

In this embodiment, the barcode is read by the scanner 2, but by operating the department key 42 and numeric keypad 43, the operator can also manually register the department code. There is.

FIG. 4 is a schematic block diagram of an embodiment of the present invention,
FIG. 5 is a diagram showing data stored in the RAM 9 shown in FIG. 4.

Next, the electrical configuration of an embodiment of the present invention will be described with reference to FIGS. 4 and 5. The scanner 2, keyboard 4, display 5, and printer 6 shown in FIG.
is connected to the CPU 7.

A ROM 8 and a RAM 9 are connected to the CPU 7 . The ROM 8 stores in advance a program based on flow factors as shown in FIG. 1, which will be described later.

As shown in FIG. 5, the RAM 9 includes storage areas 91, 92, . . . 9n, 9a, 91, 92, .
Includes 9b, 9c, 9cl and 9e. I I
J 791.92...9n constitutes the department file.

Each area includes a department hood, a totalizer, a multiplier, etc. corresponding to the department code. Storage area 9a
and 9b are used as a number buffer for temporarily storing numerical data input from the numeric keypad 43. Furthermore, the storage areas 9c, 9d, and 9e are used as work registers for temporarily storing data necessary for the CPU 7 to perform calculations.

FIG. 1 is a flow diagram for explaining vJ production according to an embodiment of the present invention.

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

First, before explaining vJ's work, I will briefly explain barcodes. Barcodes include products that are printed in advance by the product manufacturer on the product's packaging, and stores that attach a label with the barcode to the product. The latter is generally called in-store marking, and this in-store marking is used in one embodiment of the present invention.

In addition, the barcode includes UPCTYPEII and EAN1.
There are 3. tJPc TYPEII is 2X, X2
It is expressed as Xs Xi Xs C/PP+ P2 P 3P C, and EAN13 is 21 to 29X, X2
It is represented by P-Ps C. Further, ×36 of UPCTYPE II and ×2 of E A N 13 are used to indicate whether or not the product is a packaged product. In other words, it is "1" if it is a packaged product, and r if it is not a packaged product.
OJ yells. Further, X4XS of UCPTYPEI and X, X of EAN13 represent the number of packaged products. Further, P1 to P4 of UPCTYPEff and P to P of EAN13 represent unit price data of the packaged product. Note that C/P is a check digit for single tIIi data, and C is a check digit for the entire barcode.

Assume that the customer does not purchase, for example, four packaged products with the above-mentioned in-store markings, but only, for example, two. In this case, the operator causes the scanner 2 to read the barcode attached to the product. Roughly speaking, the operator inputs the quantity of the product purchased by the customer using the numeric keypad 43, and operates the x key 431 to specify that the numerical value input from the numeric keypad 43 is the quantity.

The CPU 7 determines whether or not the key input signal from the numeric keypad 43 is input manually based on the key input signal from the keyboard 4 . If the key input is performed manually from the numeric keypad 43, the input numerical data is stored in the number buffer 9d. Furthermore, C
The PU7 determines whether or not the × key 431 has been operated, and presses the ×
When it is determined that the key 431 has been operated, the numerical data stored in the numeric buffer 9a is transferred to the numeric buffer 9b. Further, the CPU 7 determines whether the registration mode is selected by the mode changeover switch 41 or not.

If the mode is a mode other than the registration mode, other processing according to the mode is performed, and if the mode is the registration mode, it is determined whether the registration is by the scanner 2 or not. This is performed based on whether or not a barcode reading signal is input from the scanner 2 to the CPtJ7.

The CPU 7 determines whether or not a barcode has been input from the scanner 2, and if the barcode is the above-mentioned UPCTYPEI.
It is determined whether it is I or not. If it is determined that the barcode is UPCTYPEI[, the X of the barcode,
is "1" or not. Sawachi, UPCT
This determination is made because the X in the YPEII barcode indicates whether it is a packaged product or not. ×3
If is "1", it is determined whether the x key 431 is being operated.

If the × key 431 is not operated, it is processed as an error. If the x key 431 has been operated, the number of packages represented by X4Xs of the barcode is stored in the work register 9c, and the package price represented by P to P is stored in the work register 9d. Then, the CPU 7 divides the package direct path stored in the work register 9d by the number of packages stored in the work register 9c, and uses the calculation result and the a number buffer? The purchase amount is calculated by multiplying 9b by the number of stored products purchased by the customer. The calculation result is stored in the work register 9e. The CPU 7 displays the purchase amount stored in the work register 9e on the display 5, and also displays the purchase amount stored in the work register 9e.
The purchase amount, department code, etc. are printed on the receipt. Then, the purchase amount data is registered in the corresponding area among the departmental areas 91, 92, . . . , 9n, and the process returns to the initial/periodal state.

Furthermore, if the barcode attached to the product is EAN13, it is determined whether or not x2 of the barcard is "1", and if x2-1, the x key 431 is operated. Determine whether or not. Then, the aforementioned tJPCTYPEI[
Similarly to the barcode, the number of packages represented by X, X of EAN 13 is stored in the work register 9c, and the package price represented by P1 to P is stored in the work register 9d. Then, the purchase amount is calculated based on the number of packages, the package price, and the key-entered number data.

In addition, if the product purchased by the customer is not a packaged product but a product sold individually, UPCTYPEI
[f7) Both X and EAN13's X2 are "1"
Therefore, the unit price data is stored in the work register 9e, and its contents are displayed and printed.

Effects of the Invention As described above, according to the present invention, when a package sales price is determined when a plurality of products are sold as a unit, the package sales price data and the package number data are barcoded for each product. Set it with
At the time of registration, the customer reads the barcode and inputs the quantity of the product purchased by the customer.The package sales price data included in the barcode is divided by the package quantity data and multiplied by the input quantity data. Since the purchase amount is calculated and registered,
It is possible to eliminate the complication of the operator having to calculate the price for one item in his head each time and keying it manually from the numeric keypad as in the past, and the registration process can be performed quickly.
