Description

[Detailed description of the invention] Industrial application field This invention is an electronic cash register (hereinafter referred to as ECR).
In particular, EC that registers data related to products whose selling prices are determined according to the weight of the product.
Regarding R.

BACKGROUND OF THE INVENTION For example, the selling price of products such as meat is determined according to the weight of the product. When data related to such products is registered in the ECR, an operator is required to input the sales weight and sales price. Such manual key operations are complicated and have the disadvantage that the registration process takes time.

Therefore, there is a method of recording a sales price corresponding to the sales weight on a product using a barcode, and 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 fixed, such as 200 yen for 100g, a customer who purchases 1kg of the product will receive 100a for 100a.
Sometimes they are sold at a discount, such as 80 yen. In such a case, 1 ka will be 1000 yen, and the above-mentioned registration using the scanner will only register the selling price, so
Even though they sold 1 ka of products, they ended up selling 900 a of products, which creates an error in 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 record not only the selling price but also the sales type, even when registering data related to a product whose selling price is determined according to the weight of the product. The goal is to manage and provide one ECR.

Means to Solve the Problems According to the present invention, the sales weight of the product and the sales price corresponding to the sales weight are attached to a product whose sales price is determined according to the sales weight using a bar code. The ECR includes a barcode reading means for reading the barcode, a first storage means for storing the registration destination department number set in advance 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 total sales weight of the corresponding product; and a second storage means for determining the type of the barcode read, and storing information from the first storage means according to the type of the barcode. and control means for reading out the department number of the registered destination 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.

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 the registration destination department corresponding to the type of the barcode is stored in the first storage means. The 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.

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

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 area 100, 101...10
Set the registration destination department number in 9. That is, the operator operates the mode changeover switch 41 to select the preset mode. Then, the user inputs a number representing the type of each barcode using the numeric keypad 43. In other words, if the barcode type is LJPCTYPEIr, rOJ, EAN
13 flag 21, rlJ, EAN13 flag 2
If the flag is 2, enter "2"; if the EAN13 flag is 29, enter "9". Then, the user operates the X key 431 to specify that the numerical data entered manually from the numeric keypad 43 is the type of barcode. After that, the operator inputs the department number using the numeric keypad 43, and presses the X key again to specify that the numerical data is the department number.
operate. In this way, the type of barcode and department number are input, and the subtotal key 441 is operated when setting the next registration destination department number. After setting all the registration destination department numbers, the cash/deposit key 442 is operated.

In this way, if you enter the registered department number manually, C
The PIJ 7 sets the input destination department number in the destination department number storage areas 100, 101, . . . , 109.

That is, when numeric data representing the type of barcode is input from the numeric keypad 43, the CPU 7 determines whether numeric data has been input from the numeric keypad in step (abbreviated as S in the figure) Sl, and determines whether or not numeric data has been input from the numeric keypad. If so, the input numerical data is stored in the electronic number buffer 111 in step S2. When the × key 431 is operated to specify that the numerical data inputted from the numeric keypad 43 is of the barcode type, the CPIJ determines whether the × key 431 has been operated in step S3 and determines whether the × key 431 has been operated. If so, the numerical data stored in the numeric buffer 111 is transferred to the numeric buffer 112 in step S4.

The CPU 7 switches the mode changeover switch 4 in step S5.
1 is switched and the program mode is selected or not is determined 3j. When it is determined that the program mode is selected, the numeric keypad 43 is pressed in step $6.
It is determined whether numeric data has been input. If numerical data has been input, the input numerical data is stored in the number buffer 111 in step S7. When the X key 431 is operated to specify that the numerical data input from the numeric keypad 43 is a department number, it is determined in step S8 whether the X key 431 has been operated. If it has been operated, the numerical data stored in the numeric buffer 111 is transferred to the numeric buffer 1112 as a department number. Therefore, the number buffer 112 stores numeric data representing the type of barcode and numeric data representing the department number.

When the subtotal key 441 is operated, the CPU 7 determines whether or not the subtotal key 441 is operated at step $10. When it is determined that the subtotal key 441 has been operated, it is determined in step 813 whether or not the number 7 lag is set.

When the numeric keypad 43 is operated, the memory area 11
Since the numeral flag is set to 3, the CPU 7 makes a determination based on whether or not the numeral flag is set in this storage area 113. If the 7 lag is not set, process an error. Further, the CPU 7 determines whether 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 815 whether the number representing the type of barcode stored in the number buffer 112 is 0 or not. If 0, UPCTYPEII
, the department number stored in the number buffer 112 is transferred to the registration destination department storage area 100.

If the content of the number buffer 112 is not O in step 815, it is determined in step 817 whether the number representing the type of barcode stored in the number buffer 112 is "1". If "1" is stored, the department number stored in the number buffer 112 is transferred to the registration destination department storage area 101 in step S18. 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. When the setting of the department number in the registration destination department number storage area 109 is completed, the CP
IJ7 is the registered department number storage area 100, 101...
- Give the data set in 109 to the printer 6 and print it.

Finally, when the operator operates the cash/deposit key 442, the CPU 7 determines in step 811 whether or not the cash/deposit key 442 has been operated, and when it determines that it has been operated, in step 812, The characters "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 the CPU 7 performs the processing in steps S1 to $5 described above, it determines in step 822 whether or not the registration mode is set, and if it is in the registration mode, the registration is performed by scan 2 in step S23. Determine whether or not. When it is determined that the registration is by the scanner 2, it is determined in step S24 whether or not the read barcode is UPCTYPEI. U.P.
If the barcode is of type C lower YPEII, the department number stored in the registration destination department number storage area 100 is stored in the register 114 in step 825 . If it is not UPCTYPE II, step S2
At step 6, it is determined whether the barcode is an EAN 13 flag 21 barcode.

If it is a barcode of EAN13 flag 21, in step 827, the registered department number storage area 10
The department number stored in 1 is stored in the register 114. In this way, depending on the type of barcode,
The department number stored in the corresponding registration destination department number storage area is stored in the register 114.

CPU 7 registers 114 at step 830 km.
The department number storage area 90 is searched based on the department number stored in . Then, in step 831,
Amount data represented by a barcode is displayed on the display 5. Furthermore, in step 832, the CP (J7) reads the name of the corresponding department and causes the printer 6 to print the name, amount data, and department number.Furthermore, in step S33, the amount data of the totalizer of the corresponding department number is printed. The CPU 7 further determines whether the barcode represents sales weight in step 834. If the barcode represents sales weight, the CPU 7 determines in step S35 the sales amount indicated by the barcode. The weight is added to the multiplier, and if the barcode does not represent the sales weight, in step 836, the number data input from the numeric keypad 43 stored in the number buffer 112 is added to the multiplier and the barcode is sequentially displayed. Terminates the operation.

Effects of the Invention As described above, according to the present invention, a bar code representing the sales weight j and sales price is attached to a product, and the bar code is read to determine the type of bar code. The department number of the registration destination according to the type of barcode is read out from the first storage means, and the second department number corresponding to that department number is read out.
Since the amount data is cumulatively stored in the storage area of the storage means, and the sales weight is also stored cumulatively, it is possible to sell the product in large quantities and discount the unit price per unit weight. Even if the product is sold in small quantities and the unit price per unit ff1ffi is increased, there will be no error in the total sales of heavy machinery.
