Abstract

PURPOSE:To expand shop management utilizing benefit points by changing point magnification in a magnification memory to magnification in receiving data at the time of receiving magnification data. CONSTITUTION:When magnification data are sent from a POS controller 2 through a transmission line 3 during the period of registering operation, the POS terminal l capable of receiving the magnification data automatically changes the point magnification in the magnification memory to point magnification in the received magnification data. When the point magnification is changed, benefit points obtained by the summing operation of commodity registration are corrected by point magnification different from the preceding one. Since the point magnification can be increased only for an optional time band of a day to provide a large benefit to customers visited within the time band, the shop management can be expanded.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a P
Related to product sales data processing and equipment such as OS (point of sale) terminals, in particular equipment that can automatically calculate reward points commensurate with the total amount of products purchased by customers;
Regarding improvements.

[Prior Art] Some retail stores, such as supermarkets and specialty stores, accumulate reward points calculated based on the sales amount of products purchased by customers on memory cards issued to the customers.
Some stores operate stores with the aim of retaining customers by offering services such as prizes based on the cumulative point value stored in the memory card.

Product sales data processing devices such as POS terminals used in such stores have a total amount memory that stores the total sales amount of products sold to one customer, and can perform the final product registration operation for that customer. When this is done, points for the total amount in the total amount memory are calculated based on the standard amount as the point standard value, and bonus points are calculated by correcting these points by multiplying them by the point multiplier. There is a known system in which the above-mentioned bonus points are accumulated and recorded on the customer's memory card attached to the customer's memory card.

Here, the point reference amount and point multiplier are set in advance in the internal memory of the POS terminal, and the settings are changed by complicated key operations on the keyboard while the setting mode is selected. Therefore, if you try to change the point multiplier or point standard amount during the registration process, the registration process will be temporarily interrupted, which may cause inconvenience to customers when the store is crowded, so changing the point multiplier is extremely difficult. Ta.

[Problems to be Solved by the Invention] As described above, in the conventional product sales data processing device that can automatically calculate bonus points commensurate with the total price, it is extremely difficult to change the point multiplier or point standard value during the registration process. Because of this difficulty, for example, it was not possible to operate a store by increasing the point multiplier only during a given time of the day and giving greater benefits to customers who came shopping during that time.

Therefore, the present invention is capable of automatically calculating points commensurate with the total amount, and allows the standard point value to be changed at a specific time without interfering with registration operations, expanding store operations using bonus points. The purpose of this invention is to provide a product sales data processing device that can measure the following:

In addition, the present invention is capable of automatically calculating points commensurate with the total amount, and the point multiplier can be changed at a specific time without interfering with registration operations, making it possible to expand store operations using bonus points. The purpose is to provide a product sales data processing device that can be measured.

[Means for Solving the Problems] The present invention has a total amount memory that is connected to a higher-level controller via a transmission line and stores the total sales amount of products sold to one customer. When the product registration closing operation is performed in the product sales data processing device that calculates and outputs points for the total amount in the total amount memory based on the point reference value, a reference value memory that stores the point reference value and a registration A reference value data receiving means receives reference value data outputted from the controller via a transmission line during business operations, and when the reference value data is received by this receiving means, the point reference value in the reference value memory is transferred to the received data. and a point reference value changing means for changing the point reference value to a reference value in the middle.

The present invention also provides a magnification memory that stores a point magnification;
a point correction means for correcting the points calculated according to the tightening operation with the point multiplier in the multiplication factor memory; a multiplication data receiving means for receiving the multiplication data output from the controller during registration work via a transmission line; The point magnification changing means changes the point magnification in the magnification memory to the magnification in the received data when the magnification data is received by the receiving means.

[Operation] According to the invention of claim 1, points for the total amount of each sales product accumulated in the total amount memory are calculated based on the point standard value in the standard amount memory by the product registration closing operation, The points are accumulated and recorded, for example, on a memory card owned by the customer. Here, the above point reference value is calculated every time the reference value data is output from the upper controller connected via the transmission line during the registration process.
It is changed according to the reference value data. Therefore, by outputting the reference value data from the controller at a predetermined time, it becomes possible to operate a store in which the point reference value is changed only during a specific time period and the content of benefits for customers is varied.

In addition, with the invention of claim 2, points for the total amount of each sales product accumulated in the total amount memory are calculated based on the point standard value in the standard amount memory by the product registration closing operation, and the points are calculated based on the point standard value in the standard amount memory. The points are corrected by the point multiplier in the multiplier memory and are accumulated and recorded, for example, on a memory card owned by the customer. Here, the point multiplier is changed in accordance with the multiplier data each time the multiplier data is output from a higher-level controller connected via a transmission line during the registration process. Therefore, by outputting the multiplier data from the controller at a predetermined time, it becomes possible to operate a store in which the point multiplier is changed only during a specific time period and the content of benefits for customers is varied.

[Embodiment] An embodiment in which the present invention is applied to a terminal in a POS system will be described below. In this embodiment, a case will be described in which the bonus points for the total amount of money spent by a customer are cumulatively recorded on a bonus card made of a magnetic card issued to the customer.

In this case, on the magnetic recording surface of the bonus card,
In addition to the customer code and store code for identifying the customer, a storage area for bonus points is provided.

Figure 1 is an overall configuration diagram of the POS system, and shows POS terminal (TM) 1.1.・・・

are connected in-line in a closed loop via the transmission line 3.

The POS controller 2 is constituted by a general computer, and is connected to each POS terminal 1, 1 . It has a built-in sales aggregation file for aggregating sales by single item, two departments, cashier, etc.

Each POS terminal 1,1. ... has the configuration shown in FIG. In other words, the CPU as the main body of the control unit
(Central processing unit) 11 has built-in arithmetic circuits, memory control circuits, etc., and performs various arithmetic processing based on input data.

21 respectively.

The ROM 13 stores program data and the like necessary for the CPU II to control each section. RAM1
4 is formed with various memories used for arithmetic processing by the CPU 11. The clock circuit 15 measures the current date and time.

The transmission 18 circuit 16 controls data transmission and reception with the POS controller 2 via the transmission line 3. A keyboard 22 for inputting product sales data manually is connected to the keyboard circuit 17.
Input the empty key signal. The display control circuit 18 displays the sales amount of the sold product.

A display 23 for displaying the total amount, etc. is connected, and the display 23 is driven to display and output two numbers and characters corresponding to the display data.

A card reader/writer 24 for reading and writing data on a magnetic card is connected to the card reader/writer control circuit 19, and data is exchanged with the card reader/writer 24.

I10 boat 20 has ``Registration'', ``Payment'', ``Inspection'', ``
A mode switch 25 for selecting and specifying various business modes such as "setting" is connected, and a selection specifying signal from this mode switch 25 is input. Another I10
A printer drive circuit 27 of a printer 26 that prints on receipts and journals and a drawer opening device 29 that opens a drawer 28 are connected to the boat 21, and a drive signal from the CPU 1 is output to each of them.

As shown in FIG. 3, the keyboard 22 has "00
” and number keys 31 from “0” to “9”, and a plurality of department keys 3 in which department codes for classifying each product are preset.
2. Various product registration keys are provided, such as a subtotal key 33 and a deposit/cash total key 34 for instructing closing of product registration by cash transaction.

As shown in FIG. 4, the RAM 14 includes a department registration buffer 41 for cumulatively registering the number of sales and sales amount of each product by department code, a point memory 42 for storing bonus points, and a store for storing items sold to one customer. A total amount memory 43 that stores cumulative sales amounts, a standard amount memory 44 that sets and stores a standard amount as a fixed point standard value used for point calculation, a multiplier memory 45 that stores a point multiplier, and the card reader/writer 24. Card flag C that is set (1) when a bonus card is installed
F flag memory 46 and the like are formed.

The CPU II is program-controlled to execute the main processing shown in the flowchart of FIG. 5 with the "registration" mode selected by the mode switch 25. That is, first, in ST (step) 1, it is determined whether or not a key on the keyboard 22 is being input. If no information has been input, it is determined in ST2 whether or not a privilege card for accumulating privilege points is attached to the card reader/writer 24. Here, when it is detected that the privilege card is attached to the card reader/writer 24, the state of the card flag CF in the flag memory 46 is checked in ST3. If the card flag CF has been reset to 1-(0), this means that the bonus card has just been inserted into the card reader/writer 24, so after setting the card flag CF (1), the card reader/writer control circuit 19 import the card data of the benefit card read by the card reader/writer 24 via the
Point memory 4 of the benefit points in the card data
2 and ends this process.

On the other hand, card flag CF is set (1
), the privilege card continues to be attached, so this process ends without doing anything.

On the other hand, even if it is detected in ST2 that no magnetic card is attached to the card reader/writer 24, ST4
The state of the card flag CF in the flag memory 46 is checked. Then, if the card flag CF is set (1), this means that the privilege card installed in the card reader/writer 24 has been removed, so after resetting the card flag CF (0), this process ends. .

On the other hand, the card flag CF is reset in ST4 (
0), this process ends without doing anything, since the privilege card remains uninstalled.

When it is determined in ST1 that there is a key input from the keyboard 22, an input key signal is taken in via the keyboard circuit 17, and the type of the input key signal is determined. Here, if the input key signal is due to a manual operation of the department key 32, it is recognized that the department registration of the product purchased by the customer has been performed, and the department key process shown in FIG. 6 is executed. That is, the sales amount and number of sales items of this department-registered product are cumulatively registered in the department registration buffer 41 for each department code. Further, the sales amount is added to the total amount memory 43. Furthermore, the corresponding department code and sales amount are displayed on the display 23, and the printer 26 is driven to print them out on the receipt and journal, and this department key processing is completed.

Assuming that the input key signal is due to manual operation of the deposit/account key 34, it is recognized that the closing operation of product registration due to a cash transaction has been performed, and the deposit/account key processing shown in FIG. 7 is performed. Execute. That is, the contents of the total amount memory 43 are checked. If the content of the total amount memory 43 is "0", it means that the deposit/cash key 34 was inputted before the product was registered, so it is determined as an error. When it is confirmed that the contents of the total amount memory 43 are greater than "0", points P are calculated by dividing the total amount in the total amount memory 34 by the reference amount in the reference amount memory 44. Next, the calculated point P is rounded down to the decimal point and corrected by multiplying the value by the point magnification in the magnification memory 45 (point correction means). Then, the corrected points are added to the point memory 42 as bonus points. Next, if the card flag CF is set, a privilege card is attached to the card reader/writer 24, so the privilege points in the point memory 34 are written to the privilege card. Thereafter, change calculation, receipt issuing, drawer opening, etc. are performed as normal deposit closing processing, and this deposit/cash key processing is completed.

In addition, the point memory 42 axes and the total amount memory 4
3 is cleared after the above deposit closing process is completed.

On the other hand, the CPU 1 is set to "
The program is controlled to periodically execute the interrupt processing shown in the flowchart of FIG. 8 with the "registration" mode selected and designated. That is, it is determined whether data is being received from the POS controller 2 via the transmission control circuit 16.

If the interrupt has not been received, this interrupt processing is ended.

On the other hand, if data sent from the POS controller 2 has been received, it is determined whether the data reception was performed normally. If the reception is not successful, an abnormal response (NAK) is sent to the POS controller 2.
and ends this interrupt processing.

If data reception is performed normally, first a normal response (ACK) is sent back to the POS controller 2. Next, the type of the received data is checked.

Here, if the received data is magnification data (magnification data receiving means), the content of the magnification memory 45 is changed to the point magnification in the received data (point magnification changing means). It also drives and controls the printer 26, prints out the point magnification in the received data only on the journal, and ends this interrupt process.

The above magnification data is automatically sent out at a preset time by the action of the POS controller 2, and is transmitted to each POS terminal 1.1. Normal response (A C
The data output is repeated several times until K) is reached.

In this embodiment configured as described above, six customers carry out shopping by bringing a privilege card issued by the store for accumulating privilege points. Then, when paying the bill, the customer hands his or her benefit card to the clerk. The clerk receives the privilege card from the customer and attaches the privilege card to the card reader/writer 24 of the POS terminal 1. Then, the cumulative value of privilege points recorded on the privilege card up to the previous time is written into the point memory 42.

Thereafter, the customer inputs the number keys 31 and department keys 32 of the keyboard 22 to register the department of the product purchased by the customer. Then, the sales amount of each product purchased by the customer is accumulated in the total amount memory 43.

When the department registration of all products is completed and the customer pays an amount corresponding to the total amount in cash, the clerk enters the payment amount using the number key 21 and then inputs the deposit/cash key 34. Then, points for the total amount in the total amount memory 43 are calculated based on the point standard amount in the standard amount memory 44, and these points are corrected by the point multiplier in the multiplier memory 45 to obtain the bonus points for the current shopping place. can get. Then, the privilege points of this current shopping place are added to the cumulative value of privilege points up to the previous time in the point memory 42, and the cumulative value of privilege points after the addition is recorded on the privilege card held by the customer.

On the other hand, when magnification data is sent from the POS controller 2 during the registration process, a POS that can receive the magnification data
In the terminal 1, the point magnification in the magnification memory 45 is automatically changed to the point magnification in the received magnification data. Then, when this point multiplier is changed,
The benefit points obtained by the subsequent product registration closing operation will be corrected at a different multiplier from the previous point multiplier.

Therefore, for example, if you operate a store that increases the point multiplier only during a certain time of the day and gives greater benefits to customers who come shopping during that time, you may want to Normal point multiplier (
For example, "1") is a larger point multiplier (-1, for example, "
2), and send out the magnification data of the normal point magnification at the end time of that time period.
A control program for the S controller 2 is designed. By doing so, the customer will be awarded greater benefit points during the relevant time period than the benefit points calculated for the same total amount at other time periods. Therefore, 1
By increasing the point multiplier at any time of the day, it is possible to give greater benefits to customers who shop during that time, thereby expanding store operations. Moreover, when changing this point multiplier, each POS terminal 1.1. ...' does not require any special key operations, does not pose a similar problem to registration operations, and is practical.

In addition, in the above embodiment, the standard amount as the point standard value is fixed and the point calculation is made different by varying the point multiplier. It may be possible to do so.

An example in this case will be described below.

This second embodiment differs from the first embodiment in that R
This embodiment is the same as the first embodiment except that the magnification memory 45 of the AM 14 is no longer required, and the point calculation processing in deposit/cash key processing and the interrupt processing for downline loading from the POS controller 2 are different. Therefore, Figures 1 to 7 are used in common.

FIG. 9 shows the deposit/cash total key processing in this second embodiment, and when the deposit/cash total key 34 is input, it is confirmed that the content of the total amount memory 43 is greater than "0". rear,
Points P are calculated by dividing the total amount in the total amount memory 34 by the reference amount in the reference amount memory 44. Next, the calculated points P are rounded down to the decimal point, and the points after rounding down are added to the point memory 42 as bonus points. If the card flag CF is set, the point memory 34
Write the bonus points in the above onto the bonus card. Thereafter, normal deposit closing processing is performed, and this deposit/cash key processing is completed.

FIG. 10 shows the CPUI 1 in this second embodiment.
This interrupt processing is periodically executed with the "registration" mode selected and designated by the mode switch 25.

Then, if data is normally received from the POS controller 2 via the transmission control circuit 16 and the received data is reference amount data (reference value data receiving means), the contents of the reference amount memory 44 are The point M value in the received data is changed to the standard amount (point reference amount changing means). It also drives and controls the printer 26, prints out the point magnification in the received data only on the journal, and ends this interrupt process.

In the second embodiment with such a configuration, for example, a store can be operated such that the standard point amount is reduced only during a given time of the day, and greater benefits are given to customers who shop during that time. If implemented, the normal point standard amount (for example, ``100
The POS controller 2 is controlled so as to transmit the standard amount data of a point standard amount (for example, ``50 yen'') smaller than the standard point amount (for example, ``50 yen''), and to send the standard amount data of the normal point standard amount at the end time of that time period. Design a program. By doing so, the customer will be awarded greater benefit points during the relevant time period than the benefit points calculated for the same total amount at other time periods. Therefore, by reducing the point reference amount only during an arbitrary time period of the day, it is possible to give greater benefits to customers who come shopping during that time period, and store management can be expanded. Moreover, when changing this point standard amount, each POS terminal 1, 1. . . ., no special key operations are required, and it goes without saying that it does not pose any problem to the registration process.

Incidentally, in each of the embodiments described above, a magnetic card was used as the privilege card, but it goes without saying that an IC card can be used by using an IC card interface in place of the card reader/writer 18. In addition, the bonus points for each customer are not cumulatively recorded on the bonus card, and, for example, P.
A file memory for each customer may be formed in the OS controller 2, and the totals may be accumulated for each customer in this file memory. Further, the present invention can also be applied to a type of system in which bonus points are printed out on a receipt for each transaction and the total is not recorded in a memory medium.

[Effect of the invention] As detailed above, according to the invention of claim 1, in the device that can automatically calculate points commensurate with the total amount,
To provide a product sales data processing device that can change a point reference value in a specific time period without hindering registration work and can easily expand store management using bonus points.

Further, according to the invention of claim 2, in a device that can automatically calculate points commensurate with the total amount, it is possible to change the point multiplier at a specific time without hindering the registration process, and use benefit points. It is possible to provide a product sales data processing device that can easily expand store operations.
