Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to an electronic cash register, and particularly to an electronic cash register having a Price Lookup (hereinafter referred to as PLU) function.

(b) Conventional technology An electronic cash register with a PUL function first sets and stores the product code and unit price of each product to be handled in the PLU storage area of the memory in a program mode, and then stores the product code and unit price of each product in a program mode. When registering, for example, when you enter the product code in registration mode, the unit price of that product will be read from the memory above, and the unit price will be automatically entered without having to enter the unit price using the numeric keys. There is. Conventionally, in electronic cash registers with PLU function, when the customer enters the code of the product purchased at the time of registration, there are some that use Scanner to automatically enter the code.
When adding new products to the PLU storage area or setting data such as product unit prices, product codes were entered using numeric keys.

(c) Problems to be solved by the invention In the above-mentioned conventional electronic cash register with PLU function, when entering a product code using numerical keys,
It is necessary to input many digits (for example, 13 digits) even for one product, and inputting many product codes is labor intensive for the operator, there is a high probability of key input errors, and the input speed is slow. It was hot.

This invention was made with attention to the above problems, and speeds up the input of product codes when setting unit prices or adding new product codes in the PLU storage area, reduces input errors, and eliminates the problem. An electronic cash register machine that requires no additional effort.

(d) Means and Effects for Solving the Problems The electronic cash register of the present invention, as shown in FIG. 21, a price search storage area 22 in which at least a product code and unit price are set and stored for each product in advance, a product code input means 23 for inputting a product code, and a product code input unit 23 in which the product code and unit price are set and stored in advance for each product; unit price reading means 24 for reading out a unit price corresponding to the product code from the price lookup storage area in response to input of a product code from the input means; It is characterized by comprising a scanner 25 for reading, and an access control means 26 for accessing the price search storage area in response to the product code read by the scanner under a program mode by the mode setting device.

In this electronic cash register, in order to access the price search storage area in the program mode, a scanner reads a product code recorded on an external storage medium, and the access area is specified using this product code. Therefore, the product code of one product is input in one scanner scan, so
Input speed is increased, input errors are reduced, and operator effort is significantly reduced.

(e) Examples The present invention will be further explained in detail below with reference to examples shown in the drawings.

FIG. 1 is a block diagram showing a schematic configuration of an electronic cash register in which the present invention is implemented. In the figure, reference numeral 1 denotes a keyboard, the key arrangement of which will be described later. 2 is a scanner for scanning and inputting printed product codes and the like. 3 is a CPU that executes predetermined processing operations according to the system program (see Figure 5) stored in the built-in ROM; 4 is a display tube that displays input data and registered data; 5 is a receipt for registering data; This is a printer that prints on journals, etc. 6
is memory that is allocated for the PLU file (storage area), work registers, and flags. The PLU file in this memory 6 is shown in Figure 2a.
As shown in the figure, the product code, unit price, number of times, and status (STATUS) can be stored in association with each of n products from PLU1 to PLUn. FIG. 2b shows the work registers and flags in the memory 6, where WORK1 is a register and WORK2 is a register for saving the contents of register WORK1. Also FKN
is the config flag, FKPLU is the PLU key flag,
FKAT indicates the unit price (@) key flag, and FKMLT indicates the (number + unit price) key flag.

The key arrangement of the keyboard 1 is shown in FIG. In Figure 4, 11 is a number key for setting numbers, 1
2 is unit price key, 13 is department key, 14 is PLU key, 15 is program mode P, registration mode
This is a mode setting device that switches and sets REG, inspection/accounting mode X, etc. The keyboard of a typical electronic cash register is equipped with many other function keys, but they are not shown because they are not directly related to this invention.

In this embodiment of the electronic cash register, scanner 2 is used to input the product code for reading the PLU file shown in Figure 2a, unit price setting, status setting, addition, and deletion. . The key and scanner operations in each case are performed in the order shown in FIG.

As shown in Figure 3-1, the PLU file is read from the scanner 2 when no key is pressed.
This is done by scanning.

The unit price setting for the PLU file is performed by scanning the scanner 2 following the operation of the numeric keys 11 for inputting the unit price, as shown in FIG. 32.

Further, the setting of status data in the PLU file is performed by inputting the status data using the numeric keys 11, operating the unit price key 12, and then scanning the scanner 2, as shown in FIG. 3.

Further, addition of a new product to the PLU file is performed by scanning the scanner 2 following the operation of the PLU key 14, as shown in FIG. 3 and 4.

Furthermore, the settings are deleted from the PLU file by scanning the scan 2 following the operation of the unit price key 12, as shown in FIG. 3 and 5.

Incidentally, in any of the operations shown in FIG. 3 above, the mode setter 15 is set to the program mode. Further, scanning by scan 2 is performed on, for example, a barcode tag or the like on which the code of the product to be input is printed.

Next, the operation of the electronic cash register of the above embodiment when each of the operations shown in 1 to 5 in FIG. 3 is performed will be explained with reference to the system flow shown in FIG. 5.

When reading PLU When the operation starts, WORK1, WORK2
Each register is cleared and each flag FKN,
FKPLU, FKPLT, and FKAT are set to 0 [step ST (hereinafter simply abbreviated as ST) 1]. Then, it is determined whether the program (P) mode is selected (ST2). If it is not the P mode, the processing routine moves to another mode, but since it is the P mode here, the process moves to the next step ST3, where it is determined whether the scanner is READY. For PLU leads, see Figure 3 1.
As shown in the figure, scanning is performed by Scanner 2 when no key is pressed, so the judgment here is YES and from then on ST4...ST
7, respectively, FKN=1 or FKMLT
It is sequentially determined whether FKPLU = 1, FKPLU = 1, or FKAT = 1, but since all of the determinations are NO, the PLU that matches the data read by the scanner 2 is read from the PLU file (ST8).

In addition, ST8 in Figure 5, ST26, ST32,
The * mark in ST37 indicates that the processing content is the same as ST16. If there is no matching data, an error process is performed, but if there is a match (ST9), the product code, unit price, and status are printed out by the printer 5 (ST10).

When setting the unit price of PLU In this case, as shown in Fig. 3, the unit price is first entered using the numeric keys 11.
Operation flow is ST1 by operating number key 11
Proceed as →ST2 →ST3. ST3 Sukiyana
The determination of READY is NO here, and the process moves to determination of whether there is a next key input (ST11). Since the judgment is YES, we next judge whether it is a number key (ST
12). As expected, it is YES, so store that value in the numeral area, that is, register WORK1 (ST1
3) and sets the flag FKN to 1 (ST14).
Then return to ST2.

After entering the unit price amount, when the product code is entered by scanning Scanner 2, ST2
In ST3 that follows, it is judged whether Sukiyana is READY.
YES, and then it is determined whether FKN=1 (ST
4). Since the flag FKN remains set to 1 in ST14, this determination is YES, and then it is determined whether the other flags FKAT, FKPLU, and FKMLT are 0 (ST15). Here if flag FKAT,
If even one of FKPLU and FKMLT is 1, error processing is performed, but normally both flags are 0, and a PLU that matches the data read by the scanner 2 is read from the PLU file (ST16). If there is no matching data, an error process is performed, but if there is a match (ST17), the number data is set in the corresponding unit price area of the PLU file (ST18). Then, the product code and status are printed out using the printer 5 (ST19).

PLU status setting In this case, status data is first entered using the numeric keys 11 as shown in FIG. By operating this number key, the operation flow is ST1→ST2→ST3→ST11→…→ST
Proceeding to step 14, the numeric data (status data) is stored in register WORK1.
This is the same as the case of unit price setting above.

When the unit price key 12 is pressed after inputting status data, the operation returns to ST2.
The process proceeds in the order of ST2→ST3→ST11→ST12, but the determination in ST12 as to whether it is a numeric key is NO, and then it is determined whether it is a PLU key (ST20).
However, since this determination is also NO, it is further determined whether it is a unit price key (ST21). This judgment is YES
Therefore, check that flags FKAT, FKPLU, and FKMLT are all 0 (ST22), and determine whether flag FKN is 1 (ST2).
3). Here, it is determined whether FKN=1 or not because the unit price key 12 is operated in the third manner.
There are cases 3 and 5, and the purpose is to distinguish between them and process them.

Here, since FKN=1, the judgment of ST23 is
YES, the contents of register WORK1 are transferred to register WORK2, and flag FKN is set to 0 (ST24). Subsequently, the flag FKMLT is set to 1 (ST25).

Following the operation of the unit price key 12, when the product code is input by scanning the scanner 2, the operation proceeds in the order of ST2→ST3→ST4 in the same way as in the above case. Determining whether FKN=1 in ST4
If NO, move to ST5 and determine whether FKMLT=1.
Since this judgment is YES, next the PLU that matches the data read by Scanner 2 is read from the PLU file (ST26, ST27), and WORK2
The save data stored in the PLU file is set in the corresponding status area of the PLU file (ST28). Then, the product code and unit price are printed out by the printer 5 (ST29).

Addition of PLU In this case, as shown in Figure 3,
PLU key 14 is pressed. This PLU key 14
The operation is ST1→ST2→ST3→
It progresses as ST11 → ST12 → ST20. ST2
Since the judgment of PLU key with 0 is YES, next each flag FKN, FKPLU, FKMLT, FKAT
It is determined whether or not is 0 (ST30). Any one
If two flags are 0, perform error handling.
If all flags are 0, then flag
Set FKPU to 1 (ST31). After that the operation is
Return to ST2.

Following the operation of the PLU designation key 14, when a product code is input by scanning the scanner 2, the operation changes from ST2 to ST.
Proceed as 3 → ST4 → ST5. flag here
Since other flags other than FKPLU are 0, ST5
The determination of whether FKMLT=1 is NO, the process moves to ST6, and the determination of FKPLU=1 is YES in ST6.

Next, it matches the data read by Scanner 2.
Read PLU from PLU file (ST3
2). If there is matching data, an error is processed as it is a duplicate, and if there is no match (ST33), the product code is registered in the PLU file (ST34). Then, print out the product code using the printer 5 (ST3
5).

Deleting PLU In this case, as shown in FIG. 3, the unit price key 12 is pressed first. When this unit price key 12 is operated, the operation goes through ST1 and ST2, and then continues as in the case of operating the unit price key 12 in the above case, ST2→ST3→ST11→ST12→ST2.
The process progresses from 0→...→ST23. FKN in ST23
= 1, but unlike the above case, the unit price key 12 was operated without the numeric key 11 being pressed, so both flags are 0 and the determination is NO. The flag FKAT is set to 1 (ST36), and the operation is ST.
Return to 2.

Following the operation of the unit price key 12, when the product code is input by scanning the scanner 2, the operation is the same as in the above case from ST2 to ST3 → ST.
Proceed as 4→…→ST6. FKPLU= in ST6
Since the determination of 1 is NO, move on to ST7.
Determine whether FKAT=1. Since this judgment is YES, next read the PLU that matches the data read by Scanner 2 from the PLU file (ST3
7) If there is no matching data, process an error, and if there is a match (ST38), delete the matching PLU from the PLU file (ST3).
9). Then, the deleted product code is printed out by the printer 5 (ST40).

(F) Effects of the Invention According to the present invention, a scanner reads a product code recorded on an external storage medium, and a price search storage area is activated in response to the product code read by the scanner in a program mode. Since it is equipped with an access control means, it is possible to input the product code of one product with one scan of the scanner, which increases input speed, reduces input errors, and significantly reduces operator effort. It has the effect of being
