Description

[Detailed description of the invention] [Industrial application field] The present invention is used in mass retailers such as supermarkets,
The present invention relates to a product sales data processing device such as an electronic cash register or a POS (point of sale) system.

[Conventional technology] For example, in a mass retailer such as a supermarket that handles a large number of products, data is managed for each product, and each product is also finely classified into departments and data is managed for each department. Departments are roughly classified into groups, and data is managed for each group.

Electronic cash registers used in mass retailers that perform such data management have data files organized by product, department, and group in internal or external memory, and each data file contains the necessary various types of information. When a product is registered for sale through a product registration operation with setting information preset, the product sales data is processed based on various setting information corresponding to the product code, department code, or group code to which the product belongs. It is configured as follows.

By the way, if the attribute system of each product is [product code x department code x group code] as described above, then the attribute department code is set corresponding to each product code in the product data file, and the department In the separate data file, attribute group codes are set corresponding to each department code, and each product is classified.

The relationship between each data file by department and group is ensured. For this reason, for example, if the attribute department code corresponding to the product code set in the product data file is not set in the department data file, the relationship between the data files will be broken and accurate data management will not be possible. occurs.

Therefore, in the past, the person in charge would print out the contents of each data file set during the configuration work and check the settings, but with this method, there was a risk of overlooking a setting error, and the work was complicated. It was becoming a burden.

On the other hand, some conventional electronic cash registers check whether the corresponding attribute group code has already been set in the group data file when setting the department code for the department data file, and then set the product code for the product data file. Some devices are equipped with an automatic setting confirmation function that checks whether the corresponding attribute department code has already been set in the department data file. This eliminates the need for the person in charge to check the contents of each data file later, but the order in which each data file is set is grouped by department.

The order is fixed by product, which limits the setting work and reduces work efficiency. Furthermore, if a code that has been set is deleted, the items belonging to that code will also become invalid, but a check is not performed in this case. There was no problem.

[Problems to be Solved by the Invention] As described above, in the prior art, it is possible to easily set the setting contents of a plurality of classified data files that are related to each other according to the attribute system of each product without imposing the same restrictions on the setting work. Moreover, it was not possible to confirm this reliably without making mistakes such as oversight.

SUMMARY OF THE INVENTION Therefore, the present invention provides a product sales data processing device that can easily and reliably check the setting contents of data files classified by L (number) that are related to each other based on the attribute system of each product, and that can improve the workability of setting work. That is.

[Means for Solving the Problems] The present invention provides a first classification file in which various setting information is preset corresponding to a first classification code for classifying each product;
It has a second classification file in which the first attribute classification code and various setting information are preset corresponding to the second classification code that classifies each product more finely than the first classification code, and the product is registered for sale by the product registration operation. In a product sales data processing device that processes product sales data based on various setting information corresponding to a first classification code or a second classification code to which the product belongs, an automatic setting confirmation key is provided, and
code reading means for sequentially reading out second classification hoods set in the second classification file in response to key input operations of the automatic setting confirmation key; and a first code reading means corresponding to the second classification code read by the reading means. Judgment means for judging whether the classification code is normally set in the first classification file, and when this judgment means judges that the first classification code is not set or abnormally set, at least the second classification code and the attribute. An abnormality code output means for outputting a code under Section 1 classification is provided.

[Function] With the present invention having such a configuration, the person in charge of settings can perform data settings for the first classification file and the second classification file without any special restrictions, and then press the automatic setting confirmation key. Perform input operations. Then, one of the set second classification codes is read from the second classification file that is smaller than the first classification file, and the first classification code corresponding to this second classification code is successfully set in the first classification file. It is determined whether the Then, when it is determined that the first classification code is not set or is set abnormally, at least the second classification code and the attribute first classification code are printed out, for example. Next, the next one of the set second classification codes is read from the second classification file, and in the same way, the first classification code corresponding to this second classification code is read out from the second classification file.
When it is determined whether or not the first classification code is set normally in the classification file, and it is determined that the first classification code is not set or abnormally set, at least the second classification code and the first attribute classification code are printed out. It will be done. therefore,
By checking the output results, the person in charge of configuration can easily identify the code that has a configuration error.

[Embodiment] An embodiment in which the present invention is applied to a single electronic cash register will be described below. In this embodiment, a case will be described in which each product is classified into two categories (PLU Nibrice Lookup) and three groups.

A key input signal from 1 is input. A display 5112 such as a CRT display capable of displaying the code of the registered sales product, the total amount, etc. is connected to the display control circuit 8, and displays the characters, numbers, etc. corresponding to the display data from the CPUI. The above I10 is displayed on the display 12.
Connected to the port 9 are a printer drive circuit 14 of a printer 13 that prints on receipts, etc., and a drawer opening device 16 of a drawer 15 for storing cash etc.
A drive signal is output to each according to a command from PU1.

As shown in FIG.
J rOJ~ A numeric key 21 for setting the number "9", a plurality of department preset keys 22 in which department codes are preset, a department key 23 for indicating that the numeric data is a department code, a numeric key 23 for indicating that the numeric data is a department code, A PLU key 24 to indicate that it is a PLU code, a small = 1 key 25 to calculate the subtotal amount of sold products when registering a product, a deposit/cash key 26 to instruct to close product registration by cash payment, etc. In addition to the product registration key, various function keys such as a multiplication key 27, a clear key 28, and a return key 29 are provided.

Here, the subtotal key 25 is used for each group and one department, which will be described later, in the "setting" mode.

The program is set to function as a zero motion setting confirmation key for each data file 31 to 33 for each PLU.

FIG. 3 is a schematic diagram showing the main memory configuration of the RAM 4. As shown in FIG. As shown in the figure, RAM 4 contains, for example, 1000
A group data file 31 in which group names and various statuses necessary for sales registration are preset for each group code in which each product is roughly classified into 20 groups;
For each department code classified into nine departments, an attribute group code indicating the group code to which the product of that department code belongs For each 6-digit PLU code, the attribute department code indicating the department code to which the product with that PLU code belongs, PLU name, unit price, inventory quantity, various statuses, etc. are preset.
In addition to the LU-specific data file 33, there is also an area 34 for the read pointer P and setting number counter n used in the automatic setting confirmation mode for each data file 31, 32, and 33.
35 etc. are formed.

Therefore, the CPUI is set to "
With "Settings" mode selected and specified, press keyboard 11.
When the subtotal key 25 is inputted, the numbers shown in FIGS. 4 to 6 are inputted.
The program is controlled to execute the automatic setting confirmation mode process shown in the figure. That is, when it is confirmed that the key input signal input via the keyboard circuit 7 in FIG. 4 is due to the input operation of the subtotal key 25,
It is determined whether or not a number was entered using the number key 21 immediately before that. Then, as ST (step) 1, “1
” is entered, the mode shifts to the automatic setting confirmation mode for the PLU data file 33 shown in FIG. In addition,
In this mode, the department code is the first classification code,
The PLU code is the second classification code, the department data file 32 is the first classification file, and the PLU data file 33
becomes the second classification file.

In FIG. 5, first, the printer 13 is driven and controlled to print out a code (for example, #01) indicating that the PLU data file 33 is in the automatic setting confirmation mode on the receipt. Next, when a number is entered in the range [0 to 999999] using the number key 21 of the keyboard 11, and then the multiplication key 27 is input, it is recognized that the automatic setting confirmation number of PLO codes has been input. Then, the set number counter n in the area 35 is set to the set number data value. Also, P.L.
The read pointer P of the area 34 is set to "1" in order to check the set number of pieces of data in the U-specific data file 33 starting from the first data.

Then, as 5T11, the PLU code set in the read pointer P is read from the PLU-specific data file 33 (code reading means). Next, the departmental data file 32 is created using the attribute department code corresponding to the PLU code.
Search and check whether the corresponding department code is set in the same file 32, and if the department code is set, whether various setting information such as status is correctly set according to the department code. (judgment means). Here, if both are true, the setting number counter n is counted down by "-1", the read pointer P is updated by "+1", and the process returns to 5TII.

On the other hand, if the corresponding department code is not set or if the various setting information is abnormally set, the printer 13 is driven to print out the corresponding PLU code, check number, and attribute department code on the receipt. error code output means). Here, the check number is information for identifying the content beyond the setting, and in this embodiment, it is set to "1" when the department code is not set, and "2" when the setting is abnormal. Thereafter, the setting number counter n is counted down by "-1", the read pointer P is updated by "+1", and the process returns to 5Tll.

In this way, STI! Repeat the following process sequentially, 5T1
If the setting number counter n becomes "0" in step 2, the printer 13 is driven to execute long receipt processing, and, for example, by automatic setting confirmation mode processing of the PLU-specific data file 33 as shown in FIG. Publish the output report and
This process ends.

In FIG. 7, 71 is a code indicating that the PLU data file 33 is in automatic setting confirmation mode, 72 is a PLU code with a setting error in the attribute department code, and 73 is a check number 74 for identifying the type of the error.
is its attribute department code.

On the other hand, in FIG. 4, if "1" is not set in STI and "2" is set in ST2, then
The mode shifts to the automatic setting confirmation mode for the department data file 32 shown in FIG. In this mode, the group code is the first classification code, the department code is the second classification code, the group data file 31 is the first classification file, and the department data file 32 is the second classification file.

In FIG. 6, first, the printer 13 is driven and controlled to print out a code (for example, #02) indicating that the department data file 32 is in the automatic setting confirmation mode on the receipt. Next, press the numeric key 21 on the keyboard 11 to select [
0 to 99], and then the multiplication key 27
When the input operation is performed, it is recognized that the automatic setting confirmation number of department codes has been input, and the setting number counter n in area 35 is
Set to the numeric data value. Further, in order to check the set number of pieces of data in the departmental data file 32 sequentially from the head data, the read pointer P of the area 34 is set to "1".

Then, as 5T21, the department code set in the read pointer P is read from the departmental data file 32 (code reading means). Next, group data file 3 is created using the attribute group code corresponding to the department code.
1, and check whether the corresponding group code is set in the same file 31, and if the group code is set, whether various setting information such as status is correctly set according to the group code. (judgment means). Here, if both are true, the setting number counter n is counted down by "-1", the read pointer P is updated by "+1", and 5
The process returns to T21.

On the other hand, if the corresponding group code is not set,
Or, if various setting information is abnormal, printer 1
3 to print out the department code, check number, and attribute group code on the receipt (abnormality code output means).

Here, the check number is information for identifying the content beyond the setting, and in this embodiment, it is set to "1" when the group code is not set, and is set to "2" when the group code is set abnormally. After that, the setting number counter n is counted down by "-1", the read pointer P is updated by "+1", and 5T21
Return to processing.

In this way, the processes after 5T21 are repeated sequentially, and 5T2
If the setting number counter n reaches "0" in step 2, the printer 13 is driven to execute long receipt processing, and an output report is issued by the automatic setting confirmation mode processing of the departmental data file 32. Finish the process.

In this embodiment configured in this way, each data file 31.32.3 is divided into groups, departments, and PLUs.
3 data setting is set by mode switch 10.
This is done by inputting a predetermined key on the keyboard 11 with the mode selected, but in this case there is no particular restriction on the setting order. That is,
It does not matter whether the person in charge starts the settings from the group-specific data file 31, the department-specific data file 32, or the PLU-specific data file 33, he/she can start the setting work from a convenient file. It's fine. Additionally, you can freely correct or cancel the data you have set.

After completing the data setting for each of the files 31 to 33 in this way, the person in charge first enters "1" in the "setting" mode, and then inputs the subtotal key 25.

Then, the automatic setting confirmation mode process for the PLU-specific data file 33 is executed according to the flowchart shown in FIG. This determines whether the attribute department code of each PLU code set in the PLU data file 33 is set in the department data file 32, and if it is set, various setting information corresponding to that department code. It is determined whether or not it is normal. Then, if the department code is not set or if abnormality information is set, the corresponding PLU code, department code, etc. are printed out. Therefore, the person in charge can easily discover data setting errors in the PLU-specific data file 33 and the department-specific data file 32 by checking the printed content.

Similarly, the person in charge enters the number "2" in the "setting" mode, and then inputs the subtotal key 25. If so, the automatic setting confirmation mode process for the departmental data file 32 is executed according to the flowchart shown in FIG. This determines whether the attribute group code of each department code set in the department data file 32 is set in the group data file 31, and if so, various setting information corresponding to that group code. It is determined whether or not it is normal. Then, if the group code is not set or if abnormality information is set, the corresponding department code, group code, etc. are printed out.

Therefore, by checking the printed content, the person in charge can
Data setting errors in the departmental data file 32 and the group data file 31 can be easily discovered.

Thereafter, by switching the mode switch 10 to the "registration" mode and operating the product registration keys on the keyboard 11 to register the product for sale, the product sales data can be changed to the PLU code, department code, or Data will be processed based on various setting information corresponding to the group code.

As described above, according to this embodiment, when performing setting work for each data file 31 to 33 for each group, department, and PLU, there are special restrictions on the setting order, correction, deletion, etc. of the setting data. The work can be carried out without any problems, and work efficiency can be improved.

What's more, by performing a simple key operation after completing the data settings, you can print out codes that may have caused a setting error, making it easy to change the settings. This reduces the burden on the person in charge, eliminates the risk of overlooking setting errors, and increases reliability.

In the above embodiment, each product was categorized into three categories: by product (by PLU), by category, and by group, but the product classification system is not limited to this, and a second classification code for detailed classification is used. The present invention is applicable to any relationship that belongs to the first classification code of the general classification.

Further, in the above embodiment, the case where the present invention is applied to a single electronic cash register is shown, but it goes without saying that the present invention can also be applied to a POS system in which a plurality of electronic cash registers are centrally managed by a controller, for example. That's a good thing.

Furthermore, in the embodiment described above, the unset code or abnormal setting code detected by the automatic setting confirmation mode process is printed out by the printer 13, but the display 12
If a screen display device such as a CRT display is used, the information may be displayed on the screen. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

[Effects of the Invention] As detailed above, according to the present invention, the setting contents of a plurality of classified data files that are related to each other according to the attribute system of each product can be easily set without imposing the same restrictions on the setting work. In addition, it is possible to provide a product sales data processing device that allows reliable confirmation without making mistakes and improves workability and reliability.
