Description

[Detailed description of the invention] [Industrial application field] This invention relates to a sales data processing device in POS, ECR, etc.

[Prior art] In an ECR (electronic cash register), the sales total memory is generally read out on each settlement date to create a settlement report, and then the memory is set and the sales are stored in the memory until the next settlement date. I am trying to register the data. In such ECR, as shown in Japanese Patent Application Laid-open No. 71071/1983, a return registration is performed when a product is returned.

[Problem to be solved by the invention] By the way, the problem here is that in the ECR as mentioned above, generally when reregistering, the date on which the product was purchased or sold, that is, the sales registration date of the product, is Regardless, the returned data is subtracted from the sales total memory, and this situation is shown in Figure 5A. C represents the time of payment (typically the payment date), and S indicates the contents of the sales total memory, which is cleared at the time of payment and in which subsequent sales data is registered. RF represents a reversal registration, and if the date of purchase and sale of the product related to this reversal registration is after the previous settlement C as shown by P2, the sales can be calculated by subtracting the value of this reversal registration from the sales total memory. The total S accurately represents the total sales after settlement. However, if the date of purchase and sale of the product related to the reversal registration is before the previous settlement C as shown by P1, and if the reversal value is subtracted from the sales total memory in the same way as above, the sales total S does not indicate the total sales data "after checkout." Despite this, the company is making corrections to these sales data.

Therefore, even for reverse registrations where products were bought and sold before the previous settlement date, such as P1, the total value is corrected by subtracting the reverse value from the total sales of S, which handles the sales data for that day. This results in inaccurate sales totals.

This is due to the fact that even products sold before the settlement date can be back-registered.

In light of this, it would seem that it would be a good idea to avoid back-registering products that were bought and sold before the settlement date.

The problem with this invention is to make it possible to back-register only products that have been bought and sold after payment.

[Means to solve the problem] The means of this invention are as follows.

A sales total memory (total memory 7-2, etc.) that stores sales data after settlement, an input means (input section 1, etc.) that inputs return data including sales date data, and based on the return data, the sales date is set to the above. It is provided with a correction control means (steps S ₂ , S ₃ , etc. processed by the CPU 2) for correcting the sales data in the sales total memory only when the total memory has been settled.

It should be noted that the information in parentheses has been added for reference in order to clearly explain how the above-mentioned means are embodied in the embodiments.

[Effect] The function of this device is as follows.

The sales total memory stores sales data after settlement. Then, when performing reverse registration, if reverse data including sales date data is input from the input means, based on this reverse data, only if the sales date is after the settlement of the above sales total memory, the above sales total memory is The sales data is corrected by the correction control means.

Therefore, reversal registration can be performed only for products that have been bought and sold after settlement.

[Embodiment] Overview FIG. 5B is a diagram for explaining the sales data processing method of the embodiment. According to this, for the return registration RF associated with the return of a product, the total value is corrected by subtracting the returned data from the sales totalizer that handles sales data at the time of purchase and sale of the product. In the first embodiment, which will be described later, each ECR side has only one sales total memory, and the total sales data from the latest settlement date C3 is registered in this memory. Then, at the time of return registration, the return data is sent to the computer on the center side, and the total value is corrected in the memories S1 and S2 that handle sales data at the time of buying and selling of the return product.

In the second embodiment, a plurality of sales total memories are prepared on the ECR side, and each sales total memory handles sales data for a predetermined period (period from one settlement to the next settlement). Total memory S
1 is from the settlement date C1 to the settlement date C2, and the second total memory is from the settlement date C2 to the settlement date C3. Correction of the sales data using the returned data is performed on the total memory related to the purchase and sale date of the product, that is, the total memory in which the sales data of the product is registered.

First Example A first example will be described with reference to FIGS. 1 to 3.

FIG. 1 is a schematic block diagram of the ECR in the first embodiment.

Reference numeral 1 denotes an input section with various keys, such as mode switching key 1-a, function key 1-b, numeric keypad 1-c, return key 1-d, PLU key 1-e, current/
In addition to a deposit key 1-f, a clear key 1-h, etc., a buzzer 1-g is also provided as a notification device. Input information from the input unit 1 is input to the CPU 2.

CPU2 controls the operation of the entire device.
It executes various programs according to an OS program stored in a ROM (not shown) and controls its peripheral devices, and has a configuration including an arithmetic unit AL, a control unit CT, and the like.

The transmission control unit 3 is an interface for communication between the CPU 2 on the ECR side and the computer on the center side, and data (for example, data for payment, return data, etc.) is transmitted to the center side according to the communication protocol. The data is sent to a computer, and the center processes the data by analyzing, aggregating, and classifying the data received from each ECR.

Drawer 4 is used to deposit and withdraw money, also known as a cash box, and its opening operation is performed by the CPU.

In addition, 6 is a printing section that contains various printing data (journal, receipt, inspection report, etc.) necessary for ECR.
Data for creating payment reports, etc.) are transferred to CPU2.
Print under the control of.

7 is a memory, which here includes elements 7-1 to 7-4. First, 7-1 is a part (hereinafter referred to as a settlement date memory) that stores the latest date when the sales data in the total memory 7-2 was settled, that is, the data of the previous settlement date. The total memory 7-2 here includes the PLU memory 7-2a and the transaction-specific memory 7-2.
The PLU memory 7-2a stores a product identification code, that is, PLUNo, data on the number of units sold for the product, and data on the unit price of the product, and the transaction memory 7-2b stores cash and credit information separately. Amount data is stored. 7-3 is the return memory, which contains the identification code of the returned product, ie, PLUNo.
and the number of data are stored. Reference numeral 7-4 is a limit date memory that stores data on the return limit date (for example, if two weeks is the limit period for return, data on a date two weeks before the current day).

The operation of the apparatus having the above configuration will be explained below within the scope directly related to this invention.

FIG. 2 illustrates key operations for registering a return upon returning a product, and the cashier operates the keys by referring to the data recorded on the receipt received from the customer. More specifically, the cashier first operates cash/deposit key 1-f, then reads the product code from the receipt, and operates numeric keypad 1-c (key 1 in the figure) and PLU key 1-e. . In the case shown, the product code of PLUNo1 is specified.
Next, operate the return key 1-d, read the date of product sales, ie, the date of product sales data registration, from the receipt, and input that date using the numeric keys.
In the illustrated example, November 6, 1984 is the sales data registration date. Finally, the cashier operates function key #.

Through the above operations, the CPU 2 interprets the key input data as returned data, executes the process shown in FIG. 3, and also transmits the returned data to the computer on the center side via the transmission control section 3.

First, referring to FIG. 3, the CPU 2 determines that the input date, that is, the date on which sales were registered for the returned product (in this case, November 6, 1984), is the return limit read from the limit date memory 7-4. It is determined whether or not it is after the current date (step S1). If it is after the return limit date, it is determined whether the input date is after the date when the last settlement was made for the total memory 7-2 (step S2). If it is later, the returned data is subtracted from the total memory in step S3. That is, in this case
Reduce the number of sold items of PLUNo1 by the number of returned items. Then, in step S4, the returned data is added to the returned memory 7-3. In this example, the number of returned products is added to the number of PLUNo1 in the return memory 7-3. Finally, in step S5, the CPU 2 executes a display command and a print command, operates the display section and the print section, and creates a journal and a receipt regarding the return registration.

If the determination in step S1 is NO, that is, if the product registration date is before the limit date, the CPU 2 program jumps to step S6, and the buzzer 1 is activated.
Executes an output command that sounds -g. As a result, the buzzer 1-g sounds, informing the user (cashier and customer) that the item in question cannot be returned. Further, if the determination in step S2 is NO, that is, if the product was purchased or sold before the previous settlement date in the total memory 7-2, the program of the CPU 2 corrects the sales data in the total memory 7-2. Jump to step S5 without any trouble.

Now, regarding the transmission of the returned data to the center side via the transmission control unit 3, this operation can be performed before or after the processing in FIG. 3, or by the subprogram when the determination result in step S2 is NO. It can be executed as In any case, the computer on the center side is the ECR that is performing the return registration.
The sales data corrected according to the returned data is sent to the period total memory (memory that handles sales data on days when products were bought and sold) under the control of the central computer. Refresh the period total memory by writing .

Second example A second embodiment will be described with reference to FIG.

The second embodiment differs from the first embodiment in that a plurality of total memories are provided on the ECR side. FIG. 4 shows a memory added to the memory 7 in FIG. 1,
PLU memory 1 handles sales data from one settlement date 1' to the next settlement date 2, and similarly, PLU memory 1 handles sales data from settlement date i' to settlement date (if settlement is done every day) This memory handles sales data up to i'-1). The total memory currently in use is the total memory 7-2 shown in FIG.

Describing the operation of return registration in the second embodiment, the key operations are the same as in the first embodiment, but
CPU processing is slightly different. To explain this with reference to FIG. 3, in the second embodiment, step S2
If the judgment is NO, the input date, that is, the PLU where sales data has been registered for the returned product.
Executes processing to determine memory. Then, the sales data correction process described in connection with step S3 is executed on the determined PLU memory, and then the process proceeds to step S4 in FIG.

The rest is the same as the first embodiment, so it will not be described in further detail.

[Effects of the invention] According to this invention, reverse registration can be performed only for products bought and sold after the settlement date. Therefore, the inspection report and the settlement report accurately show the sales data within the period, eliminating the unreasonableness that existed in the past, and having a great practical effect.
