Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product sales registration data processing device such as an electronic cash register having a PLU (price look up) registration function and a POS (point of sale information management) terminal.

[0002]

2. Description of the Related Art A conventional product sales registration data processing device having a PLU registration function stores product information such as the name and unit price of a corresponding product in correspondence with a PLU code set for each product, and the number of sales points. , RAM of product information file with cumulative sales amount area for each PLU code
(Random access memory), hard disk drive, etc.

When the PLU code of the sold product is input through an input means such as a keyboard or a scanner, the product information file is searched and the product information corresponding to the input PLU code is read. Then, the unit price in the read product information is multiplied by the sales point to calculate the sales amount, and the sales point and the sales amount are added and registered in the sales point total area and the sales total area corresponding to the input PLU code of the product information file, respectively. To do. In addition, the name, unit price,
The product registration detail information such as the number of items sold and the amount of sale is displayed and output on the display unit, and is also printed out on receipt paper or the like by a printer. This completes the PLU registration of one product.
In addition, the sales point is defined as the sales point if the registration is performed by the registration key immediately before the PLU code is input, and the sales point is set to "1" if the registration is not performed.

By the way, retail stores do not always sell all products at the unit price set in the product information file during business hours. For example, as a part of customer service, there is a method of reducing the unit price of a product designated for special sale to a flat charge and selling the product at a preset time zone.

Therefore, conventionally, a unit price change key for declaring a unit price change is provided on a keyboard, and a numerical value is entered by a numeric key following the key input of this unit price change key, and then P
When the LU code is entered, the unit price in the product information corresponding to the input PLU code read from the product information file is changed to a numerical value that has been entered, and the sales registration process is performed to temporarily change the unit price. I was able to deal with.

[0006] Further, a plurality of unit prices are set in the product information of each product in the product information file, and a flag for designating which unit price among these unit prices is valid is set. Some have made it possible to respond to temporary changes in unit prices by automatically changing them.

[0007]

However, in the conventional product sale registration data processing device provided with the unit price change key, the unit price in the product information set in the product information file is temporarily changed and the product is sold. Each time you register a product, you must enter the changed unit price with the number key, so
In addition to complicated operations, there were cases where sales registration processing was performed at an incorrect unit price due to a mistake in operating the numeric keypad.

On the other hand, in the conventional product sales registration data processing apparatus in which a plurality of unit prices are set in the product information, the above-mentioned problem does not occur, but the product information amount of each product is set in order to set a plurality of unit prices. Since the size of the product information file is increased, it is difficult to reduce the cost of the product due to the large capacity of the product information file, which is unsuitable for a simple model.

Therefore, the present invention is capable of reliably changing the unit price by one-touch operation, improving the operability, reducing the storage capacity, and reducing the cost. Is to provide.

[0010]

The present invention has a product information file for storing at least the product name and unit price product information corresponding to a code set for each product. When the code of the sale item is input, the item information corresponding to the input code is read out from the item information file and the item sale data is processed in the storage unit. When the unit price preset key and the unit price preset key are operated by the code input means and the unit price preset key is operated, the unit price in the unit information corresponding to the input code read from the unit information file is preset. Unit price changing means to change to the unit price data preset in the key, and the unit price by this changing means Based on the product information over data is changed is obtained a change bid registration means for sales registration processing commodity sales data in the storage unit.

[0011]

According to the present invention having such a configuration, when the sales registration of the product to be temporarily registered by changing the unit price to the unit price data of a predetermined amount preset in the unit price preset key, Enter the code and operate the unit price preset key. Then, the unit price in the product information corresponding to the input code read from the product information file is changed to the unit price data preset in the unit price preset key, and the unit price data is based on the changed product information. Is registered in the storage unit for sales.

Now, this POS terminal 1 has the above-mentioned R
A PLU file 31 shown in FIG. 4 is formed in the AM 13 as a product information file. This PLU file 31
Stores the name, unit price and PLU product information of the changeable flag corresponding to the PLU code of each product, and also serves as a storage unit for registering the product sales data, and the cumulative number of sales points and sales amount. Areas are provided for each PLU code.

Here, the changeable flag is a flag for setting whether or not the unit price of the corresponding product can be changed from the unit price set in the PLU file 31, and is composed of 1 bit, for example, "1". When it is set to "", it can be changed, and when it is reset to "0", it cannot be changed.

P for the PLU file 31
LU product information can be set, for example, in the business before opening a store.
This is performed by down line loading from a host device connected through the communication interface 15.

As shown in FIG. 5, the RAM 13 also stores a numeral buffer 32 for temporarily storing the numeral data by the numeral keys 2b, a unit price area 33 for temporarily storing the unit price data after the change of the product to be sold, and a sales area. "1" when changing the unit price of a product
Flag area 34 of the unit price change flag F set to
The PLU information area 35 for temporarily storing the PLU product information of one product read from the PLU file 31, the first
~ Various memory areas such as a unit price preset key table 36 for storing unit price data of a predetermined amount of money set respectively for the third unit price preset keys k1 to k3 are formed.

Therefore, the POS terminal 1 is a code (for example, "99") for instructing the start of the unit price data setting operation to the unit price preset key table 36 when the "setting" mode is selected by the mode switch 9.
When the x key 2e is operated and input after entering the number, the CPU 1
1 is programmed so as to start the unit price data setting work shown in the flowchart of FIG.

That is, when starting the unit price data setting work, the CPU 11 waits for a key input from the keyboard 2. When it is detected that the first unit price preset key k1, the numeral key 2b, and the execution key 2h are operated in this order, the unit price data set for the first unit price preset key k1 is stored as the numeral unit key 2b. Since the numerical value has been input by, the numerical value data in the numerical value buffer 32 is stored in the area 36a corresponding to the first unit price preset key k1 of the unit price preset key table 36.

When it is detected that the second unit price preset key k2, the numeral key 2b and the execution key 2h are operated in this order, the unit price data set for the second unit price preset key k2 is stored. Since the numerical value has been input by the numerical key 2b, the numerical data in the numerical value buffer 32 is stored in the area 36b of the unit price preset key table 36 corresponding to the second unit price preset key k2.

Similarly, the third unit price preset key k3
When it is detected that the numerical keys 2b and the execution key 2h are operated in this order, the unit price data set for the third unit price preset key k3 is input by the numerical keys 2b. Third of the preset key table 36
Numerical data in the numeral buffer 32 is stored in the area 36c corresponding to the unit price preset key k3.

When the operation input of the deposit / cash total key 2f is detected, the end of the unit price data setting work is declared, so the work is ended.

In the POS terminal 1, when the "register" mode is selected by the mode switch 9, the first to third unit price preset keys k of the keyboard 2 are selected.
The CPU 11 is configured to execute the processing shown in the flowchart of FIG. 7 when the user inputs 1 to k3 or the unit price change key 2g.

That is, when the CPU 11 detects the operation input of the first unit price preset key k1 in the "registration" mode, the unit price stored in the area 36a in the unit price preset key table 36 corresponding to the first unit price preset key k1. The data is read and stored in the unit price area 33. After that, the unit price change flag F in the flag area 34
Is set to "1", and this processing ends.

When the CPU 11 detects the operation input of the second unit price preset key k2 in the "registration" mode,
The unit price data stored in the area 36b corresponding to the second unit price preset key k2 in the unit price preset key table 36 is read and stored in the unit price area 33. After that, the unit price change flag F in the flag area 34 is set to "1", and this processing ends.

When the CPU 11 detects the operation input of the third unit price preset key k3 in the "registration" mode,
The unit price data stored in the area 36c corresponding to the third unit price preset key k3 in the unit price preset key table 36 is read and stored in the unit price area 33. After that, the unit price change flag F in the flag area 34 is set to "1", and this processing ends.

When the CPU 11 detects the operation input of the unit price change key 2g in the "registration" mode, it waits for the changed unit price data to be input. And the numeric key 2
When the numerical data is entered by b, and the execution key 2h is subsequently operated, the changed unit price data is entered, so that the numerical data in the numerical buffer 32 is stored in the unit price area 33. After that, the unit price change flag F in the flag area 34 is set to "1", and this processing ends.

Further, in the POS terminal 1, when the "register" mode is selected by the mode switch 9, the PLU code attached to the product is scanned and input by the bar code scanner 8 and the CPU 11 The program is configured to execute the processing shown in the flowchart of FIG.

That is, when the CPU 11 detects the input of the scanned PLU code in the "registration" mode, the CPU 11 uses the input PLU code as a search key to generate the PLU code.
The LU file 31 is searched. If the PLU code that matches the input PLU code cannot be detected, it is determined that the PLU code of the product for which the PLU product information is not set in the PLU file 31 has been read, and this processing ends.

On the other hand, when a PLU code matching the input PLU code is detected as a result of searching the PLU file 31, the PLU product information of the name, unit price and changeable flag corresponding to the input PLU code is read. And stores it in the PLU information area 35.

Next, the unit price change flag F in the flag area 34 is examined. Here, when the unit price change flag F is reset to “0”, the product corresponding to the input PLU code is the product for which sales registration processing is performed at the normal unit price set in the PLU file 31, so the PLU information area The sales price is calculated by multiplying the unit price in the PLU product information stored in 35 by the sales point, and the sales point and the sales amount are respectively stored in the sales point total area and the sales total area corresponding to the input PLU code of the PLU file 31. Register for addition. Further, the product registration detail information such as the name, unit price, number of sales, and sales amount in the PLU product information is displayed and output on the displays 3 and 4, and the printer 5 prints it on receipt paper or the like.

On the other hand, when the unit price change flag F is set to "1", the changeable flag in the PLU product information stored in the PLU information area 35 is checked. here,
When the changeable flag is set to "1", the unit price change is not permitted, so the unit price change flag F is reset to "0" and then the PLU product stored in the PLU information area 35. Calculate the sales amount by multiplying the unit price in the information by the number of points sold
Addition registration is performed in the total sales amount area and the total sales amount area corresponding to the input PLU code of the U file 31, respectively. In addition, the name, unit price, number of items sold,
The product registration detail information such as the sales amount is displayed and output on the displays 3 and 4, and the printer 5 prints and outputs it on a receipt paper or the like.

On the other hand, when the changeable flag in the PLU product information stored in the PLU information area 35 is reset to "0", the product corresponding to the input PLU code is set in the PLU file 31. Stored in the PLU information area 35 because the normal unit price is a product for which the sales price is changed by changing the unit price input by operating the first to third unit price preset keys k1 to k3 or the unit price change key 2g. The unit price in the PLU product information is changed to the unit price stored in the unit price area 33 (unit price changing means).

Thereafter, the unit price change flag F is reset to "0", the unit price after change in the PLU information area 35 is multiplied by the number of sales points to calculate the sales amount, and the sales number and the sales amount are set in the PLU file 31. Are additionally registered in the total sales amount area and the total sales amount area corresponding to the input PLU code. Further, the product registration detail information such as the name in the PLU product information, the changed unit price, the number of sales, the sales amount and the like is displayed and output on the displays 3 and 4, and the printer 5 prints it on receipt paper or the like.

This completes the PLU registration for one product. In addition, the sales point is set by the numeric key 2b immediately before entering the PLU code.
If a multiplier is entered using the and x keys 2e, the multiplier is taken as the sales point, and if no multiplier is entered, "1" is taken as the sales point.

In the POS terminal 1, when the "registration" mode is selected by the mode switch 9, the preset PLU key 2a of the keyboard 2 is operated or the numeric key 2b and the PLU key 2d are operated. Even when the PLU code is input by key input, the CPU 11 is configured to execute the same processing as the processing shown in the flowchart of FIG.

In the POS terminal 1 of the present embodiment having such a configuration, the PLU file 31 is preset with the PLU product information of each product by the DLL work from the host device. In this case, in the time zone of the time service, the unit price is reduced to the special sale price and the PLU product information of the special sale product is set as the normal unit price before discount and the changeable flag is changeable. It is set to "1" shown. In the PLU product information of products other than the special sale product, the normal unit price is set as the unit price, and the changeable flag is reset to "0" indicating that the change is impossible.

By performing the unit price data setting operation in advance, the first to third unit price preset keys k1 to k1
Unit price data of a predetermined amount can be preset for each k3.

For example, a product whose uniform unit price after discounting by time service is 100 yen, a product whose price is 500 yen, and 100
In the case of a retail store in which three types of 0 yen products are available as special sale products, the first to third unit price preset keys k1 to k
Uniform unit price of 100 yen, 500 yen and 1 for 3 respectively
You only have to set 000 yen.

Now, it is assumed that the data "100" is set in the area 36a, the data "500" is set in the area 36b, and the data "1000" is set in the area 36c of the unit price preset key table 36 by executing the unit price data setting work. To do. At this time, the first unit price preset key k1
, A uniform unit price of 100 yen, a second unit price preset key k2 of a uniform unit price of 500 yen, and a third unit price preset key k3 of a uniform unit price of 1,000 yen. .

In this state, a clerk operating the POS terminal 1, a so-called cashier, operates the scanner 8 or the keyboard 2 to input the PLU code of the product purchased by the customer during the time period other than the time service.

By doing so, the PLU file 31
The PLU product information corresponding to the input PLU code is read from the product, product sales data is obtained based on the normal unit price in the PLU product information, and registration processing is performed for each PLU code in the cumulative sales area of the PLU file 31.

On the other hand, in order to register the sales data of the special sale product in the time zone of the time service, first, the unit price preset keys k1 to k3 in which the uniform unit price after the price reduction of the special sale product is preset are operated. Then, the PLU code of the special sale product is input.

By doing so, the PLU file 31
The PLU product information corresponding to the input PLU code is read from, and the normal unit price in this PLU product information is changed to the uniform unit price preset in the operated unit price preset keys k1 to k3. Then, product sales data is obtained based on this uniform unit price, and is registered in the cumulative sales area of the PLU file 31 for each PLU code.

For example, when registering a product which is discounted to a uniform unit price of 100 yen by the time service, the cashier may input the PLU code of the corresponding product after operating and inputting the first unit price preset key k1. Similarly, in the case of registering a product which is discounted to a uniform unit price of 500 yen, it is sufficient to input the PLU code of the corresponding product after operating and inputting the second unit price preset key k2.
When registering a product discounted to a yen, after operating and inputting the third unit price preset key k3, the PLU of the corresponding product is registered.
Just enter the code.

It should be noted that the unit price preset key k1 is erroneously registered at the time of sales registration of a product which is not discounted during the time service period.
Even if the user inputs k3 to k3, the changeable flag in the PLU product information of the corresponding product is reset to “0”, so the product sales data is obtained based on the normal unit price in the PLU product information, and the PLU file 31 Registration processing is performed for each PLU code in the sales cumulative area.

As described above, according to the present embodiment, the first to third unit price preset keys k1 to k3 for presetting unit price data of a predetermined amount of money are provided, and the code of the sale product is displayed via the scanner 8 or the keyboard 2. When the unit price preset keys k1 to k3 are operated and input,
The unit price in the PLU product information corresponding to the input code read from the PLU file 31 is changed to the unit price data preset in the operation input unit price preset keys k1 to k3, and the unit price data is changed to the changed PLU product information. Based on the above, the product sales data is registered in the cumulative sales area of the PLU file 31 for each PLU code. Therefore, the temporary unit price change can be performed by the unit price preset keys k1 to k.
It can be surely performed by one-touch operation of 3.

Therefore, in addition to improving the operability when changing and registering the unit price set in the PLU file 31, even one type of normal unit price is set in the PLU file 31 as the unit price data of each product. PLU
The capacity of the file 31 can be reduced, and the cost of the POS terminal 1 can be reduced.

Further, since a changeable flag is provided in the PLU product information to automatically determine whether the unit price can be changed or not, the unit price preset keys k1 to k3 are set.
Even if there is an erroneous operation, the sales registration process can be performed at an accurate unit price, and the reliability can be improved. The changeable flag is 1
Since it is a bit, the storage capacity can be significantly reduced compared to the case where a plurality of unit prices are set.

The present invention is not limited to the above embodiment. For example, although three unit price preset keys are provided in the above embodiment, the number of unit price preset keys may be one or two. Needless to say, four or more pieces may be provided and different uniform unit prices may be set for each.

Also, in the case of performing sales registration processing of a product whose sales price is changed by changing the unit price to "0" yen, for example, an all-you-can-eat (all-you-can-drink) service product of a restaurant, the unit price preset key is set. The present invention can be applied by setting the uniform unit price to be "0" yen.

Of course, various modifications can be made without departing from the scope of the present invention.

[0060]

As described above in detail, according to the present invention, a unit price preset key for presetting unit price data of a predetermined amount of money is provided, and the code of the sale item is inputted by the code input means and the unit price preset key is operated. When entered, the unit price in the product information corresponding to the input code read from the product information file is changed to the unit price data preset in the unit price preset key, and the product price is changed based on the changed product information. Since the sales data is processed to be registered in the storage unit, the temporary unit price can be reliably changed with one-touch operation, improving operability and reducing the storage capacity and cost. A product sales registration data processing device can be provided.
