Description

[Detailed description of the invention] Industrial application field This invention is an electronic cash register (hereinafter referred to as ECR).
In particular, the present invention relates to an ECR in which unit price data is recorded on a product as a barcode, and data regarding the product is registered by reading the barcode with a scanner.

In conventional ECR technology, department codes are set as barcodes on products in order to simplify key operations for operators.
There is a method of reading the barcode with a scanner and registering unit price data corresponding to the product code included in the read barcode one after another from the PLU file.

Problems that the invention aims to solve By the way, some stores issue membership cards, and customers who display the card may be sold at a certain discount on the sales price of the products. . For such products, a regular unit price and a unit price discounted by a certain amount are determined. However, in an ECR that reads barcodes using the above-mentioned scanner,
Normally, a PLU file has only one piece of unit price data set for the product, so in order to register the discounted unit price data, the operator must enter the unit price data manually using the numeric keypad.

This makes the operator's key operations complicated, and the effect of rapid registration using a scanner is diminished.

Therefore, it is possible to set two types of unit price data in the PLU file and select one of them depending on the key on the keyboard, but in order to set two types of unit price data, it is necessary to set two types of unit price data in the PLU file. The drawback was that it required a large amount of memory.

Therefore, the main object of the present invention is to provide an ECR that can simplify the operator's key operations and reduce the memory capacity even when selecting and registering one of two types of unit price data. It is to provide. Means for Solving Problem 1 In the present invention, first and second unit price data are attached to the product using a bar code. The ECR includes a barcode reading means for reading the barcode, a selection means for selecting the second unit price data, a storage means for storing the total sales price of the product, and a control means. configured.

In this invention, when a barcode attached to a product is read by the barcode reading means, the first unit price data represented by the barcode is stored in the storage means, and the barcode is read. And in response to the operation of the selection means, the second unit price data represented by the barcode is stored in the storage means. Therefore, the operator can register the first unit price data simply by reading the barcode with the barcode reading means, and when registering the second unit price data, the operator reads the barcode with the barcode reading means and operates the selection means. You can register the second unit price data just by

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.

In addition, the barcode includes UPCTYPE■ and EANl.

1A and 1B are flowcharts for explaining the operation of one embodiment of the present invention, FIG. 6 is a diagram showing the key operation procedure when setting the registration destination department number, and FIG.
The figure is a diagram showing a key operation procedure at the time of registration.

Next, with reference to FIGS. 18 to 7, specific operations of an embodiment of the present invention will be described.

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, according to the key operation procedure shown in FIG. 6, a number representing the type of each barcode is inputted from the numeric keypad 43. In other words, the barcode type is UPCTY.
rOJ for PEII, rlJ for EAN13 flag 21, "2" for EAN13 flag 22, etc.
If the EAN13 flag is 29, input "9".

Then, the user operates the X key 431 to specify that the numerical data inputted from the numeric keypad 43 is of the type of barcode. After that, the operator enters the department number on the numeric keypad 4.
3, and operate the X key 431 again to specify that the numerical data is a department number. In this way, the barcode type 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 PU7 sets the input destination department number in the destination department number storage area 100.101...1o9. That is, the CPtJ 7 performs step ("When numerical data representing the type of barcode is input from the numeric keypad 43,"
In Sl (abbreviated as S in the figure), it is determined whether or not numeric data has been input from the numeric keypad. If numeric data has been input, the input numeric data is stored in the 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 CPU 7 determines whether or not the × key 431 has been operated in step S3, and determines whether the × key 431 has been operated or not. If so, in step S4, the numerical data stored in the numeric buffer 111 is transferred to the numeric buffer 112.

The CPU 7 switches the mode changeover switch 4 in step S5.
1 is switched to determine whether the program mode is selected. When it is determined that the program mode is selected, it is determined in step S6 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 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 operated, position buffer 1
The numerical data stored in 11 is transferred to the number buffer 112 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 in step 810 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 813 whether or not the number flag 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 numeric flag is not set, handle 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 S15 whether the number representing the type of barcode stored in the number buffer 112 is 0 or not. If 0, UPCTYPEII
Since the barcode is a barcode, the department number stored in the 11 digit buffer 172 is transferred to the registration destination department storage area 100.

If the contents of the numeric buffer 112 are not 0 in step 815, it is determined in step 817 whether the number representing the type of barcode stored in the numeric 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 818. 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
U7 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 returns cash/? in step 811. lj
It is determined whether or not the i-key 442 has been operated, and if it is determined that it has been operated, the printer 6 prints the words "END PRINT" in step 812.

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 manually presses the keys according to the key operation procedure shown in FIG. That is, when a customer displays a membership card, for example, in order to set the second unit price data, the user operates the M key 421, places the product purchased by the customer on the scanner 2, and reads the barcode. let If the customer does not display a membership card, press the M key 42 to register the first unit price data.
The product purchased by the customer is placed on the scanner 2 and the bar code is read without operating the scanner 1.

After performing the processing of steps S1 to S5 described above, the CPU 7 determines in step 822 whether or not the registration mode is set, and if the CPU 7 is in the registration mode, determines in step 823 whether the registration is by the scanner 2 or not. Determine whether If it is determined that the registration is by scanner 2, it is determined in step 824 whether or not the read barcode is IJPcTYPEI. U
If the barcode is of type PCTYPEI[, the department number stored in the registration destination department number storage area 100 is stored in the register 114 in step 325. If the barcode is not UPCTYPEI,
In step 826, it is determined whether the barcode is an EAN 13 flag 21 barcode. If it is a barcode of the EAN13 flag 21, the department number stored in the registration destination department number storage area 101 is stored in the register 114 in step 827. this
(Thus, 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, and the process proceeds to step 830 shown in FIG. 1B.

In step 830, the CPU 7 stores the department number storage area 9 based on the department number stored in the register 114.
Search for 0. Then, in step 831, it is determined whether the flag F2 is set. This flag F2 is set to memory area 1 when the M key 421 is operated.
It is set to 13. If flag F2 is not set, the first unit price data read from the barcode is displayed in step S32, and if flag F2 is set, the second unit price data read from the barcode is displayed in step S32. Display data. That is, M
If the key 421 is operated, the second unit price data is displayed on the display 5, and if the M key is not operated, the first unit price data is displayed.
unit price data is displayed on the display 5. Step 834
, the CPU 7 prints the corresponding department number and unit price data.

In step S35, CPLI 7 determines whether flag F1 is set. This flag F1 is set in the storage area 113 when the x key 431 is operated. When this flag F1 is set, it indicates that the customer has purchased multiple items of the same product.

Therefore, if the flag F1 is set, in step 836, the first or second unit price data is multiplied by the input number stored in the number buffer 112 to obtain the total amount, and the total amount is calculated by the corresponding department number. Add to the totalizer in the storage area of . In step S37, the flag F
It is determined again whether or not 2 is set, and if it is set, the input number is added to the counter B in the storage area 903 in step 838. If the flag F2 is not set, the input number is added to the multiplier A in the storage area 902 in step S39.

In the judgment in step S35 described above, if the flag F1 is not set, the number of purchased products is one, so in step 840, the first or second unit price data of that product is added to the totalizer, and in step 841 It is determined whether the flag F2 is set.

If flag F2 is set, 1 is added to multiplier B in step S42; if flag F2 is not set,
In step 843, 1 is added to the multiplier A and the series of operations ends.

Effect of the invention .

As described above, according to the present invention, the first and second unit price data are attached to the product using barcodes, and when registering the unit price data of 'Igi, the , when storing the first unit price data represented by the barcode in the storage means and registering the second unit price data, the second unit price data represented by the barcode is stored by operating the selection means and reading the barcode. unit price data can be stored. Therefore, when registering the first unit price data, the operator only needs to read the barcode with the barcode reading means, and when registering the second unit price data, the operator only needs to read the barcode by operating the selection means. In order to avoid
Complicated key operations can be reduced. Furthermore, since it is not necessary to store the first F3 and second unit price data in the memory, the memory capacity can be reduced.
