Abstract

PURPOSE:To decrease the processing time for classifying and totalling transaction data by saving temporarily a classification and totalling data stored in a storage section corresponding to the unit transaction data until the registration of the data of the unit transaction is finished. CONSTITUTION:When one of transaction data is inputted from a keyboard 5, a main control section 14 starts a file control section 8 and the transaction data is stored in a transaction data storage area of the file section 7 by a storage pointer 8a. Moreover, the classification and totalling data corresponding to the said transaction data is outputted from the classification and totalling data storage area of the file section 7 by an output pointer 8b and stored in a saving data buffer 10. Then the transaction data and the classification and totalling data stored in the file section 7 are read by the output pointer 8b, they are summed at an arithmetic section 4b and stored in the original position of the file 7 by the storage pointer 8a so as to update the classification and totalling data.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention
The present invention relates to a transaction data processing method of an electronic register in a system (hereinafter referred to as PO3), and particularly relates to a transaction data processing method that can shorten the time for classifying and aggregating transaction data.

Background of FBL Technology Recently, with the spread of computer network systems, electronic cash registers have been widely used as PO3 terminals in department stores and supermarkets.

Electronic registers are operated by operators such as store clerks,
The product prices are sequentially displayed on the display, and finally the total price is displayed by pressing a button.A receipt is issued for each sales transaction by the printer, and a journal is recorded at the same time.

In addition to this register function, it sends sales information by product online one by one to a computer center, and plays an input function for an information management system that comprehensively performs product management such as sales aggregation, inventory management, and purchase management.

Then, the electronic register processes and stores transaction data according to predetermined product or item classifications for each transaction, and transmits the data to a terminal controller (hereinafter referred to as T/C), which is a host device.

Therefore, it is desirable that the data processing speed be high.

fcl conventional technology and problems Below, we will discuss the conventional method using an electronic register as an example.
This will be explained with reference to the drawings and FIG. FIG. 1 is a perspective view showing an electronic register to which the present invention is applied, and FIG. 2 is a block diagram showing a conventional method.

As shown in FIG.
．． Printer section 3. Control unit 4. It is composed of a keyboard section 5, cash, and a drawer 6.
On the top surface, a printer section 3 and a control section 4 are arranged on the left and right, a keyboard section 5 is arranged in front, and a display 2 is arranged in contact with the rear of the keyboard section 5.

A receipt issuing port 3a and a slip insertion port 3b are provided at the center of the top surface of the printer section 3.

The slip insertion slot 3b is used to insert a slip when printing and issuing a slip (not shown) in a non-cash transaction 1, for example, a transaction using a credit card.

With such a configuration and function, a signal is sent to the control unit 4 by an operation input from the keyboard unit 5 by an operator (not shown), and a command signal from the control unit 4 allows the product number, product name, unit price, and operation to be sent to the operator to be sent to the control unit 4. The instructions are displayed one by one on the display 2, and finally, the necessary calculation processing is performed and the total amount and change etc. are displayed.

As the transaction data is entered, a receipt and journal (not shown) are printed by the printer section 3, and finally, when the total amount and the like are printed, the receipt is issued from the receipt issuing port 3a.

Next, the cash drawer 6 opens and comes forward, allowing cash to be disbursed and disbursed.

When the transaction is completed, the transaction end button 5a is pressed, and the transaction data for each transaction is sent to the i''/C (not shown).In the electronic register 1, the data is stored according to predetermined product classifications, as will be described later. The classified and aggregated data is updated by adding human-generated transaction data.

If the operator makes an operational error during this time, a warning or the like is displayed on the display 3 so that the error in processing can be corrected.

There is also a method of inputting transaction data by using a barcode reading device to read the barcode written on the packaging of the product, etc., instead of having the operator operate the keyboard unit 5, but this method will not be explained here. Omitted. Note that the electronic register 1 can be used in either method.

In the electronic register 1, transaction data is input by inputting the product number code or single item code that digitizes the product or product group, and inputting the price of the product to input one single item, which is repeated once or multiple times. , the total processing becomes one transaction.

Then, for each transaction, the data is updated by adding the classification to the data that has already been classified and aggregated.

Department stores, supermarkets, etc. usually classify the types of products they handle into many categories in order to obtain appropriate sales information.

In this case, to explain how to update the above input transaction data, in FIG. 8b is a storage pointer, 8b is an output pointer, and 9 is a printer control unit.

The main control section 4a includes a storage section 4b and a calculation section 4C.

The storage capacity of the storage unit 4b is equivalent to the storage capacity of the total data storage area of the file unit 7.

After the classification and aggregation processing of one transaction data is completed, all the classification and aggregation data are sent to the file section 7 and also stored in the storage section 4b.

The file section 7 includes a storage area for recording transaction data and a storage area (heart total area) for storing classification and total data.

The file control section 8 accesses transaction data and classification total data from the file section 7, and includes a storage pointer 8a and an output pointer 8b.

The storage pointer 8a is used to specify in which area of the file section 8 transaction data and classification summary data are to be stored.
The output pointer 8b specifies in which area of the file section 7 data stored is to be output.

The printer control section 9 controls the print output of the printer section 3.

With such a configuration and function, when the input of transaction data begins, the transaction data is sequentially stored in the storage area specified by the storage pointer 8a, and the transaction data is stored in the storage section 4b of the main control section 4a. The arithmetic unit 4c adds the classification total data to the already stored corresponding classification total data to update the classification total data.

On the other hand, the transaction data is totaled for one transaction and is printed out by the printer section 3 as described above.

When the classification and aggregation processing for one transaction is completed, all the classification and aggregation data in the storage section 4b are sent out, and the classification and aggregation data stored in the file section 7 are updated according to instructions from the storage pointer 8a.

If the transaction is canceled, the transaction cancellation button 5b on the keyboard section 5 is pressed, and the update of the classification and total data stored in the storage section 4b is aborted midway.

In either case, the classification and total data in the file section 7 is sent to the storage section 4b for the next transaction, and the latest classification and total data is held in both.

In this way, classification and aggregation are performed for each transaction.

However, according to this method, all the classified and aggregated data has a large amount of data, and it takes time to transfer all the classified and aggregated data between the file section 7 and the storage section 4I+.
There is a disadvantage that transactions cannot be processed in time when there are many customers, and there is also a disadvantage that the storage section 4b needs to have a large capacity memory, which is uneconomical.

On the other hand, when the classification and aggregation processing for one transaction is completed and the data is sent from the storage section 4b to the file section 7, the data held in the storage section 4b is used for the classification and aggregation of the next transaction. However, if the transaction is canceled, the data processing in the storage section 4b is discontinued, so it is also possible to transfer the classification and total data from the file section 7 for the next transaction.

However, although this method improves the data transfer time except on the hour during a transaction, the data transfer increases only when a transaction is canceled, making the control complex and requiring a large amount of memory. There are drawbacks that cannot be improved.

(d1 Purpose of the Invention The purpose of the present invention is to solve the above-mentioned drawbacks, and to shorten the processing time for classifying and aggregating transaction data.
Another object of the present invention is to provide a transaction data processing method that can reduce the memory capacity of the device.

te1 Structure of the Invention The present invention provides a saving means for reading out and temporarily storing the classification collection 81 data stored in the storage unit corresponding to the transaction data included in the unit transaction, and registering the transaction data in the unit transaction. This is a transaction data processing method that temporarily stores the classified and aggregated data before updating until the transaction is completed, thereby achieving the purpose.

([) Embodiment of the Invention Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 3 to 5.
C.Explain. 3 is a block diagram showing an embodiment according to the present invention, FIG. 4 is an explanatory diagram of FIG. 3, and FIG. 5 is a flowchart 1 of FIG. 3. The same reference numerals indicate the same objects throughout the figures.

In FIG. 3, 10 indicates a save data buffer, and 14 indicates a main control section.

The save data buffer 10 stores the classification summary data of the file section 7 corresponding to the product classification included in one transaction, and as shown in FIG. 4, when transaction data is input, the classification summary data of the file section 7 is stored. The component classification summary data corresponding to the storage area is saved and stored in the save data buffer 10. Since it stores as many classification and total data as there are product categories included in one transaction, the memory has a very small capacity compared to the classification and total data storage area of the file section 7.

The main control unit 14 is the main control unit 4a described in the conventional example in FIG.
In this case, the storage section 4b is omitted.

With such a configuration and function, when one piece of transaction data is input from the keyboard section 5, as shown in FIG. The transaction data is recorded in the transaction data storage area of the file section 7, and the output pointer 8b causes the classification and total data corresponding to the transaction data to be output from the classification and total data storage area of the file section 7, and the saved data is saved. It is stored in the buffer 10.

Next, write 1. in the file section 7. The transaction data and the classified total data are read out by the output pointer 8b, are totaled by the calculation section 4b, and are stored again in the original position of the file section 7 using the storage pointer 8a to update the classified total data.

The transaction data sequentially input in this manner is stored in the file section 7, and the classified and aggregated data corresponding to the transaction data is saved in the save data 8 sofa 10, and the classified and aggregated data in the file section 7 is updated.

If transaction data of the same classification group as the previously saved classified aggregated data is input within one transaction, the data is aggregated and updated without being saved.

When the transaction ends and the transaction end button 5a is pressed, all the transaction data in the file section 7 is output, summed up in the calculation section 4b, and printed out, while the saved data Huffer 1o is cleared and the file section 7 The updated classification summary data is retained as is.

In addition, if the transaction is canceled during the transaction, 1
When the button 5b is pressed, the reading classification summary data that had been saved in the save data buffer 1o is returned to its original position in the file section 7 by the storage pointer 8a, and the data is transferred to the save data buffer 1.
o is cleared and the state before the transaction is restored.

In this way, only the classified and aggregated data included in one transaction is saved in the saved data buffer 1o, and the file section 7
Since the cheek cake total data is updated, the save data 8 sofa 1o only requires a small memory capacity, and in the case of 1 no 2 during the transaction, the data of the save data bar sofa 1o is saved in the file section 7.
Since there is no need to transfer all classified data before and after the transaction, the transaction data processing time can be reduced.

(6) As described in detail, according to the present invention, in the transaction data classification and aggregation processing, only the classification and aggregation data corresponding to the categories included in one transaction are saved, and the classification aggregation and update processing is performed. Therefore, ■ transaction processing time is shortened, and it is possible to handle cases where there is a large number of customers.

■Memory can be made smaller.

There is an effect.
