Abstract

PURPOSE:To simplify an operation when returned merchandise is processed and to prevent an erroneous operation by preventing the processing of the returned merchandise from being executed when the price of the returned merchandise is not inputted. CONSTITUTION:A control means is provided to judge whether the price of the returned merchandise is inputted or not when processing the returned merchandise and to prevent the processing from being executed when the price of the returned merchandise is not inputted. Therefore, when the returned merchandise is processed, the processing is not executed unless the price of the returned merchandise is not inputted. Accordingly, a sales staff checks the price at the time of purchase without fail and input the price and an amount corresponding to the price at the time of purchase is paid black without fail. Thus, a reliable relationship between a customer and a store is not damaged and reliability for the summed-up result of sales data is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field J] This invention is applicable to ECR (electronic cash register), P
The present invention relates to a sales data processing device such as an OS register or an electronic scale for face-to-face sales, and more specifically, to a sales data processing device that performs return processing operations to prevent erroneous operations from occurring.

``Prior Art'' In a store or the like, a customer may, for some reason, bring back a product he or she has previously purchased and wish to return it. Therefore, in preparation for such cases, conventional EC
R5POS systems, electronic scales for face-to-face sales, etc. are equipped with a "return" key. When returning a product, first press the "Return" key, the ECR etc. will go into return processing mode, and then the store clerk will have a barcode reader (scanner) read the product code (barcode) of the returned product. , ECR, etc. execute return processing based on the read product code.

``Problems to be solved by inventions'' By the way, in retail stores, etc., depending on the product,
There are some items whose prices differ from day to day, or from morning to evening. If you purchase such a product yesterday and return it the next day, or if you purchase it in the morning and return it in the evening of the same day, the price of the product has been updated, so you will no longer be able to use the product code of the product in the barcode. Accurate return processing cannot be performed only by having the reader read the item. Therefore, in this case, it is necessary to input the price at the time of purchase.

A similar problem also exists when returning bundled products.

Here, bundle selling is a sales method that gives a discount if you purchase several products at once (Japanese Patent Laid-Open No. 61-23
Publication No. 4492). For example, if a customer buys three items that cost 40 yen each, they will be sold at a discount of 20 yen, so the customer only has to pay 100 yen for the three items. Therefore, in the conventional ECR etc., in preparation for such a case, it is possible to input the price of the returned product using a numeric keypad. In other words, if you need to enter the price of a returned product, first click "Return".
Press the key, then enter the price of the returned item,
Finally, the return process is performed by having a barcode reader read the product code of the product.

As described above, in conventional ECRs and the like, even in the same return process, there are times when the price does not need to be entered, and the store staff has to make this decision each time, which is complicated for the store staff. Therefore, there was a risk of erroneous operation and trouble with customers. Additionally, there were cases in which accurate sales performance data could not be collected. As a way to solve these problems, a POS system has been proposed that prevents store staff from making operational errors by displaying information when returning products, entering product codes, and when unit prices have changed. (Japanese Unexamined Patent Publication No. 61-275996).

However, this method requires the following (a) to (c).
There are drawbacks. (b) So-called PLU (Pr1ce) stores product data such as product name and unit price for each product code.
(Look Up) It is necessary to set an item in the file to indicate whether or not the unit price has changed for each product.
By simply displaying that the unit price has been changed, it is not possible to determine whether the return is for an item purchased before the unit price change or a change for an item purchased after the unit price change, and in the end, the store staff must make their own judgment. (c) Returns of bundled products are not considered at all.

Therefore, even with the above proposal, the problems of complicated operation and risk of erroneous operation have not been solved.

This invention was made in view of the above circumstances, and aims to prevent the occurrence of erroneous operations during return processing.

1. Means for Solving Problem 1 To solve the above problem, the invention according to claim I determines whether or not the price of the returned product has been input during the return processing, and determines whether the price of the returned product is It is characterized by having a control means that does not execute return processing if no input has been made.

The invention according to claim 2 is provided with a return key that prompts the control means to execute the return process, and when the control unit is prompted to execute the return process by pressing the return key.
The present invention is characterized in that means is added for causing the display unit to display a screen requesting input of a price at the time of purchase of the returned product.

"Operation" In the above configuration, when executing the return processing, the return processing will not continue unless the price of the returned product is entered. Therefore, the clerk always checks and inputs the price at the time of purchase. Therefore, since the amount equivalent to the purchase price will definitely be refunded, the relationship of trust between the customer and the store will not be damaged. Furthermore, the reliability of the sales data aggregation results can also be improved.

"Example" Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the external structure of an ECH which is an embodiment of the present invention, and FIG. 3 is a block diagram showing the electrical structure thereof.

First, the mechanical configuration will be explained.

In FIG. 1, reference numeral 1 indicates a keyboard arranged at an angle within the reach of a store clerk (checker), and is composed of a function key 1a, a numeral key lb, and a preset key 1c. . 2 is a barcode reading window, and inside this reading window 2, there is a reading window 2.
A barcode reader 3 (see FIG. 3) is provided to read code data from the barcode printed portion of the product that crosses the barcode. Reference numeral 4 denotes a display device for displaying the product name, price, total purchase amount, and various messages of the purchased product, and includes a clerk side display device 4a placed on the slope facing the store clerk, and a display device 4a placed on the slope facing the customer. It consists of a customer side display 4b. Reference numeral 5 denotes a printing device, which is comprised of a journal printing section 5a that prints purchase data on a journal and a receipt printing section 5b that issues a receipt to a customer. In addition, 6 is a coin case, 7 is a bill case, 8 is an accessory case, 9a is a platform provided at the entrance side (entrance side counter) for placing purchased products, and 9b is a platform provided at the exit side ( (Exit side counter), IO is a control unit housing part that houses the control unit 11 (FIG. 3).

FIG. 2 is a partial configuration diagram showing a part of the above-mentioned keyboard I. Keys that are particularly important in carrying out the return processing operation described later are the numeric keypad 1b, r "return" key HK, and "amount" key KK. It is. In the return process, the numeric keypad 1b is used to enter the return amount, and the "return" key H
K is a key for starting the return processing, and the "amount" key KK is a key for confirming input of the return amount.

Next, the electrical configuration will be explained.

In FIG. 3, 1 and 12 are CPUs (
I3 is a ROM (read only memory) that stores a control program used in the CPUI 2, 14 is a RAM (random access memory) for storing data, and 15 is a display controller that controls the display device 4. 15. 16 is a printer controller that controls the printing device 5; 17 is an external interface;
I8 is a keyboard interface for connecting the keyboard 1 and CPU 12, 19 is a barcode reader 3
This is a barcode interface for connecting the CPU 12 and the CPU 12. The control section 11 is constituted by each of these sections 12-19.

As shown in FIG. 4, the RAM 14 is provided with a flag/register area 14a, a PLU data area 14b1, and a total data area 14c. The flag/register area 14a is comprised of a "return" key flag, an amount register, and the like. Here, click "Return"
When the "return" key HK is pressed, "I" is stored in the key flag, which means that it is time to process a return. In addition, after entering a number in the amount register using the numeric keypad tb, if you then press the "amount" key KK, the numeric keypad! The value entered in b is now stored. The PLU data area 14b is composed of a JAN file 14b+ and a bundle file 14b. The above JAN file 14tz contains JAN
(Japanese Article Number)
For each product code to which the code is applied, the product name, unit price,
Data such as department and manufacturer are stored. According to the illustrated example, "XX chocolate" and "40" (yen) are registered in the product name and unit price columns corresponding to product code r123456J, respectively.
This means that the unit price of chocolate is 40 yen.

Further, the bundle file 14b2 stores a product code, bundle number, and bundle price in correspondence with the bundle number. According to the illustrated example, r123456J is in the product code field, "3" (pieces) is in the bundle quantity field, and rlooJ ('yen) is in the bundle price field, which correspond to the bundle number "2I". Each item is registered, but this means that if you purchase three pieces of ×× chocolates at once, you only have to pay 100 yen (instead of paying 120 yen), which means you get a 20 yen discount. . In addition, the above aggregate data area 1
4c is set as a record file 14c+ that stores the number of sales items and sales amount for each product code.

Next, the return processing operation by ECH in this example will be explained.

Note that the following are prerequisites for performing the return processing using ECH in this example.

First, if a customer wishes to return an item, they must bring the item they wish to return and the receipt of purchase. Then, the store clerk looked at the returned product and the receipt that he had brought,
It is necessary to confirm the price (return amount) of the returned product at the time of sale. In this case, if the product is normally sold, there is no particular problem since it is clear that the price printed on the receipt is the price of the product at the time of sale.

However, there are the following problems with products sold in bundles (XX Chocolate, see Figure 4). For example, if you are purchasing 3 pieces of XX chocolates that cost 40 yen each, and you have decided to discount the price by 20 yen, you can purchase 1 entourage item after purchasing the 3 pieces of XX chocolates at once. In this case, the return amount will be 20 yen, but if the customer buys only one or two items and then buys another item, the return amount will be 40 yen. A situation may arise in which the amount returned will differ depending on whether or not the item was purchased. Therefore, the store clerk needs to check the receipt and confirm whether the product is a bundled product or not.

FIG. 6(a) is a diagram showing an example of a receipt issued when a bundled product is purchased.

In this figure, numeral 20 is a receipt, and for each registration of XX Chocolate, "Matomomeuri 21" and "XX Chocolate *¥40" are printed. Here, [Matomomeuri 21J is XX Chocolate is bundle number r2
]J (see Figure 4) indicates that it is a bundled product. When you purchase the third ×× chocolate, [×
×Chocolate *￥40” is printed under the text “Matoumeuri 21 θI 00/3ko”, but this is because it is part of a bundle sale, meaning that if you purchase all three pieces, the total price will be 100 yen. The intention is to lower the price. Then, under the above-mentioned section of "Matomomeuri 21 θ100/3", "Matomome discount -20J" indicating that the discount amount is 20 yen is printed. When the store clerk looks at the receipt 20 and confirms that the product is sold in a bundle, it is necessary to calculate and confirm the returned amount from the printed contents of the receipt.

Based on the above premise, the return processing procedure in ECH of this example will be explained with reference to the flowchart of FIG.

■When operating the "Returns" key HK When the clerk (checker) presses the "Returns" key HK,
From this, the CPU 12 starts executing the subroutine shown in FIG. First, in step SAI,
After setting the return key flag to “l”, step SA
Proceed to step 2 and display "Please enter the returned amount" (
Figure 7(a)). After displaying, the CPU 12 returns to the main routine.

■When operating the "amount" key KK At this point, the store clerk, prompted by the above-mentioned amount input request display, enters the returned amount and then presses the "amount" key KK. Here, we will introduce 3 pieces of XX Chocolate, which is a bundled product.
Let's take as an example a case where a customer wants to return one of the items after purchasing them in bulk. Therefore, the returned amount is "20" yen. When the "amount" key KK is pressed,
From this, the CPU 12 starts executing the subroutine shown in FIG. 5(b). First, in step SBI, it is determined whether the returned amount (amount data) has already been entered. When the result of the judgment is rYEsJ, that is, when the number is set, the process advances to step SB2, where the returned amount is stored in the amount register and the "amount of 20 yen" is displayed (
Figure 7(b)). After displaying, the CPU 12 returns to the main routine. On the other hand, if rNOJ is determined in step SBI, that is, if the return amount is not entered, it is an operation error, and the process proceeds to step SB3, where a buzzer or the like is used to issue a warning that there is an operation error.

After issuing the alarm, the CPU 2 returns to the main routine. In addition, in step SB3, instead of the warning, a display indicating that there is an operation error may be displayed, or the warning may be issued and displayed.

■When entering the product code Next, the store clerk uses the barcode reader 3, numeric keypad Ib and function key 1a, or preset key 1c.
If you enter the product code by operating such as, from this,
The CPU 2 starts executing the routine shown in FIG. 5(C). First, in step SCI, it is determined whether the return key flag is set to "I", that is, whether or not it is time for return processing. At this time, if the return key flag is "0", it means that it is not the time to process a return.
The process moves to another processing routine, for example, registration processing.

On the other hand, if the return key flag is set to “I”,
Proceeding to step SC2, it is determined whether the returned amount has been input, that is, whether the content of the amount register is not "0". If the result of this judgment is "NO", that is, if the returned amount has not been input, step SC
6, a warning is issued by a buzzer or the like to the effect that an operation error has occurred.

After issuing the alarm, the CPU 12 returns to the main routine. In this way, the return process cannot be executed unless the return amount is input. On the other hand, when the result of the judgment in step SC2 is rYESJ, that is, when the returned goods amount has been input, the process advances to step SC3, and the result file 14
The data in the sales points column and sales amount column corresponding to the returned product (XX chocolate) in c1 is subtracted and updated. As a result of the subtraction update, the contents of the sales points column corresponding to XX dco rate (product code r123456J) in the performance file l4c+ were r130J (pieces) before the update, but now they are "I29" (pieces). Also, the content of the sales amount column was r4600J (yen) before the update, but it has changed to "4600J (yen)".
It will be 580J (yen). Next, the CPU 12 moves to step SC4, displays the return data (see FIG. 7(c)), and prints out the return data to create a return receipt (step 6).
(See figure (b)). Note that FIG. 6(b) is an example in which a return receipt is created for each -item even if there are multiple returns. Then, the process moves to step SC5, the content of the return key flag is reset to "0", and the return process is completed.

The store clerk will send the generated return receipt and the returned amount to 6 Give it to the customer.

Thus, according to the above configuration, the following effects can be obtained.

(b) The return process will not continue unless the price of the returned product is entered, so the price at the time of purchase is always checked and entered. Therefore, definitely
Since the amount equivalent to the purchase price is refunded, it is favorable for both the customer and the store. Additionally, it becomes possible to collect accurate sales data.

(b) Since the clerk only has to operate according to the guide displayed on the display device, the operations during return processing are standardized and operations are simplified.

In addition, in the above-mentioned Example, the case where it was applied to ECH was described, but it is not limited to this, but can also be applied to a POS system and an electronic scale for face-to-face sales. When applied to a POS system, PLU data and aggregated data are stored in the parent ECR or store controller IC.
). Furthermore, when applied to a scale for face-to-face sales, the price of a weighed product is determined at the time of sale based on its weight and unit price.

In addition, in the above embodiment, the case of bundle sales of the same kind of products was described, but this is not limited to this case. Bundle sales of different kinds of products, for example, the unit price of product A is 50 yen,
The unit price of product B is 60 yen, but when purchasing products A and B together, the sales method can be applied to a sales method in which the price is discounted by 10 yen and the customer only has to pay 100 yen.

Further, the operation examples, display examples, and printing examples in the above embodiments are not limited to the above. For example, as an example of printing in return processing, in the above embodiment, the discount amount is printed on the receipt of the bundled product when the third product is purchased, but the price after the discount is printed. It may also be printed.

"Effects of the Invention" As is clear from the above explanation, the sales data processing device of the present invention simplifies operations during return processing, and also enables AI□ 8 to prevent erroneous operations. and maintain a relationship of trust with store owners.
