DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a POS (Point Of
The present invention relates to a merchandise sales registration processing device that functions as a merchandise sales registration terminal or the like of a Sales point-of-sale information system.

[0002]

2. Description of the Related Art In a retail store such as a supermarket, a special sale period and a special sale target product are set in advance, and during the special sale period, the special sale target product is sold at a special sale price discounted from a normal price, thereby securing customers. There are many places that are trying to make it. As a conventional merchandise sales registration processing device capable of easily processing such a bargain sale, the following is known.

[0005] That is, a product information storage unit in which a normal price, a bargain price, and a flag for identifying whether or not a bargain item is set for each product is provided in advance, and a bargain information storage unit in which a bargain period is set is provided. Then, when the product purchased by the customer is registered by the product registration means, it is first determined from the flag whether or not the product is for sale. Then, if the product is a bargain sale target, it is next determined from the information in the bargain sale information storage unit whether or not the current time is within the bargain sale period. If it is during the special sale period, the registered product is processed for sale at the special sale price. If it is outside the bargain period or out of bargain sales, the registered merchandise is sold at the normal price.

[0004] By using the conventional merchandise sales registration processing apparatus having such a special sale processing function, an operator (casher) can check whether a sold product is a special sale target or not and what the special sale price is. Purchased products can be registered, which is efficient.

[0005] Also, there has been known a merchandise sales registration processing apparatus which is provided with means for declaring a member transaction, and executes the above-mentioned special sale processing only when a member transaction is declared by the declaring means. By using this kind of merchandise sales registration processing device, it is possible to provide a bargain service only to customers who have previously contracted for membership by simple operations.

[0006]

By the way, at the stage of considering the purchase of a desired product, the shopper confirms that the product is a target for bargain sale by means of a newspaper insert advertisement or the like. Are encouraged to come and shop. However, since it is not possible to promote the willingness to purchase other products, customer retention has been insufficient.

[0007] Therefore, as one sales method for retaining customers, a customer who has purchased a product targeted for a special sale plan should purchase a product targeted for a special sale in the next or subsequent special sale plan. A possible method is to sell the product at a price that is further reduced from the special sale price. Such a sales method is called a chain sale method. However, the conventional merchandise sales registration processing device having the special sale processing function cannot simply process the above-described chain sale system.

Accordingly, the present invention provides a discount to a customer who has purchased a product targeted for a special sale plan at the next or subsequent special sale plan when the user purchases the product targeted for a special sale. It is an object of the present invention to provide a merchandise sales registration processing device which can easily process a chain special sales system for selling at a reduced price.

[0009]

The invention described in claim 1 of the present application stores a normal price for each product, stores setting information as to whether or not the product is a target for a special sale plan, and stores the setting information for the product for a special sale plan. Is provided with product information storage means for storing prices in the special sale plan. Further, there is provided a special sale plan information storage means for selectively storing a special sale plan code and discount information of another special sale plan to be discounted for each special sale plan code for identifying the special sale plan. Further, there is provided a customer-specific sale history accumulation means for updating and accumulating the purchase history of the special sale plan target product for each customer as needed. Thus, when the merchandise purchased by the customer is registered by the merchandise registration means, it is determined from the information stored in the merchandise information storage means whether or not the registered merchandise is a product targeted for sale planning. Then, when the registered product is determined to be a product not covered by the special sale plan, the registered product is sold at a normal price. On the other hand, if the registered product is determined to be a product targeted for a special sale plan, the information stored in the special sale plan information storage means as to whether or not another special sale plan to be discounted is set for the special sale plan. judge. Then, when it is determined that another discount plan to be discounted is set, the presence or absence of a purchase history of a product sold in another discount plan to be discounted is determined from information accumulated by the customer-specific sale history storage unit. judge. Then, when it is determined that there is a purchase history of the product sold in the other special sale plan to be discounted, the registered product is discounted from the price in the special sale plan by the discount information of the other special sale plan to be discounted. Process sales by price. On the other hand, when it is determined that there is no other special sale plan to be discounted, and when it is determined that there is no purchase history of the product sold in the other special sale plan to be discounted, the registered product in the special sale plan is determined. The sales are processed at the price of

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. This embodiment is a case where the present invention is applied to a product sales registration terminal of a POS system, that is, a so-called POS terminal. Check the purchase history of the target product, and if it is confirmed that you have purchased the target product of another special sale plan that is eligible for discount for this special sale plan (this is called chain sale plan), purchase This is a case where a service for selling the product at a further discount from the special sale price is implemented.

FIG. 1 is a schematic diagram of a POS system according to the present embodiment. A plurality of POS terminals are connected to a store computer 1 for managing data of the entire store via a communication line 2 such as a LAN (Local Area Network). 3 are connected.

The store computer 1 stores a single item master file 4 functioning as merchandise information storage means, a special sale master file 5 functioning as special sale plan information storage means, and a member master file 6 functioning as customer-specific special sale history storage means. Have.

As shown in FIG. 2, the single item master file 4 stores a single item name, a normal unit price, a special unit price, and a special sale planning code corresponding to the individual unit code unique to each item set for each item. This is a data file in which information such as information is set and stored in advance. Here, the normal unit price is a selling price at the time of excluding the special sale plan. The special sale unit price is a sale price at the time of a special sale plan object. The special sale plan code is a code for identifying a special sale plan.

As shown in FIG. 3, the special sale master file 5 is a data file in which, in correspondence with each special sale plan code, a name for specifying the special sale plan and the start date and end date of the special sale period are set and stored in advance. It is. In the present embodiment, in particular, a plan code and a discount rate of another special sale plan which is a discount target for the special sale plan, that is, a so-called chain special sale plan, are selectively set and stored.

As shown in FIG. 4, the member master file 6 corresponds to a member code assigned to each member, along with member-specific information such as a member name and a telephone number, as well as a bargain sale plan purchased by that member. It is a data file for storing bargain sale data, which is a history of target products. Here, as shown in FIG. 5, the special sale plan sales data includes a special sale plan code and the last sale date of the target product in the special sale plan identified by the special sale plan code.

FIG. 6 is a block diagram showing a main configuration of the POS terminal 3. As shown in FIG. That is, the POS terminal 3
CPU (Central Processing Unit) as control unit
11 is mounted. A ROM (Read Only Memory) 12 storing fixed data such as a program, a RAM (Random Access Memory) 13 having various memory areas for storing variable data, a clock unit for measuring date and time 14, a communication interface 15 for controlling data communication with the store computer 1 connected via the communication line 2, a signal from the mode switch 16 is inputted, and the drawer opening device 17 for automatically opening a drawer (not shown) is driven. I / O port 1 that outputs signals
8. Keyboard 1 with various keys required for product registration
A keyboard controller 20 for taking in a key signal corresponding to a key operation from 9; a scanner controller 22 for taking in a code signal read by a scanner 21 which optically reads a bar code or a two-dimensional data code which symbolizes at least a single item code; An operator display 23 for displaying the name, price, etc. of the registered product to the operator.
A display controller 25 for controlling a display operation of a customer display 24 for displaying a product name, an amount, and the like of a registered product to a shopper; a printer controller 27 for controlling a printing operation of a printer 26 for performing receipt printing and journal printing;
A card reader controller 29 for taking in card data read by the card reader 28 is mounted. The CPU 11, the ROM 12, the RAM 13, the clock unit 14, the communication interface 15, the I / O port 18,
Keyboard controller 20, scanner controller 2
2, display controller 25, printer controller 27
And a card reader controller 29 via a bus line 30 such as an address bus and a data bus.

The keyboard 19 and the scanner 21 are used to input a single item code of a product to be purchased by a customer, and constitute a product registration means. Further, the keyboard 19 includes a subtotal key for instructing the total output of the products purchased by one customer, a closing key for declaring registration closing of the products purchased by the one customer, and the like.

The mode switch 16 is used for “register”,
Various business modes such as “check”, “payment”, and “setting” are selected, and the execution is instructed to the CPU 11. Here, "registration" means that when a product for sale is registered by the product registration means of the keyboard 19 and the scanner 21, the sales data of the registered product is processed for sale in the storage unit, and the closing key is used to execute a commercial transaction with one shopper. This is a business mode in which, when the closing registration is performed, a receipt recording the details of the product purchased by the shopper in the commercial transaction is printed and issued by the printer 26. “Inspection” is a task of outputting the contents of the storage unit in which sales data of each product has been registered by the registration task. The “payment” is a business mode in which, after outputting the contents of the storage unit in which the sales data of each product is registered by the registration operation, the contents of the storage unit are cleared. The “setting” is a business mode in which data necessary for executing a registration business or the like is set in the storage unit.

The card reader 28 is for reading card data of a membership card.
The member number of the member who owns the member card is recorded. When a magnetic card is used as a member card, a magnetic card reader is used, and when an IC card is used, an IC card reader is used.

Each POS terminal 3 secures an area for storing each local file of the commodity master file 4 and the special sale master file 5 provided in the store computer 1, respectively, in the RAM 13. The local files of the master files 4 and 5 are downloaded from the store computer 1 to each POS terminal 3 via the communication line 2.

As described above, since each POS terminal 3 has the local file, the process of inquiring the store computer 1 for the merchandise information and the bargain information is omitted, and the processing speed is improved and the communication traffic amount is reduced.

As shown in FIG. 7, the RAM 13 further includes a member number memory 31 for storing a member number, a record memory 32 for storing a member master record, and a member memory for processing member transactions. It forms a flag memory 33 for member transaction flags that are set to "1" during transaction processing. In addition, a flag memory 3 of a registering flag which is set to “1” while a product for one transaction is being registered.
4 are formed.

The POS terminal 3 has a program so that the CPU 11 executes the processes shown in FIGS. 9 to 11 when the "registration" mode is selected by the mode switch 16. FIG. 9 shows “Registration”
CPU 11 when member number is input in mode
This is the process. That is, when the card data read by the card reader 28 is the member card data, and the member number is recognized in the card data or the member number is input by key input of the keyboard 19, the CPU 11 inputs the member number. Start processing.

First, the registered flag in the flag memory 34 is checked as ST (step) 1. Here, if the registering flag is set to “1”, it is an erroneous operation of inputting the member number during the registration of the merchandise of one transaction, so that an input error occurs.

On the other hand, if the registering flag has been reset to "0", an inquiry message is created with the member number input as ST2. Then, the communication interface 15 is controlled to transmit the inquiry message to the store computer 1 via the communication line 2. The store computer 1 that has received the inquiry message searches the member master file 6 with the member number in the inquiry message, and reads out the member master record including the corresponding member number. Then, a response message including the member master record is transmitted to the inquiry source POS terminal 3 via the communication line 2.

Therefore, the POS that sent the inquiry message
The CPU 11 of the terminal 3 waits for a response message as ST3. Then, the communication interface 1 within a certain time
When it is confirmed that a response message from the store computer 1 has been received via the storage message 5, a member master record is extracted from the response message and stored in the record memory 32. Thereafter, if the member transaction flag in the flag memory 33 is set to "1" in ST5, the member number input processing is terminated. If a response message cannot be received within a predetermined time in ST3, a system error is determined.

FIG. 10 shows the processing of the CPU 11 when the product registration is performed by the product registration means in the "registration" mode. That is, the single item code of the product for sale is
The CPU 11 starts this merchandise registration processing when scanning is performed by the key 1 or key input is performed by the keyboard 19.

First, the registered flag in the flag memory 34 is checked as ST1. If the registration flag has been reset to "0", the first sale item has been registered in one transaction, and the registration flag is set to "1" in ST2. If the registering flag has already been set to "1" in ST1, the second and subsequent sales products have been registered in the first transaction, so that the processing in ST2 is not performed.

Next, the local file of the single item master file 4 is searched by the single item code input as ST3. Then, the unit name, the normal unit price, the bargain unit price, the bargain planning code, and the like corresponding to the unit code are read out. next,
In step ST4, the member transaction flag in the flag memory 33 is checked. Here, if the member transaction flag has been reset to "0", it means that the transaction is with a non-member, so that the conventional product registration process is executed.

If the member transaction flag is set to "1" in ST4, it is a transaction with the member, so it is determined in ST5 whether or not the sales product registered this time is a product for sale planning. Here, the local file of the special sale master file 5 is referred to with the special sale plan code acquired in the process of ST3, and if the current date measured by the clock unit 14 is during the special sale period corresponding to the special sale plan code, the special sale is performed. Judge as a product for planning. If it is outside the special sale period, it is determined that the product is not a target of the special sale plan (product determination means).

If it is determined in ST5 that the product is not the target of the special sale plan, the normal unit price acquired in the process of ST3 is recognized as the unit price of the selling product in ST6. And
Proceeding to ST12, this unit price is added to the number of sales points (or the multiplier if a multiplier is keyed in immediately before input of the single item code,
If the multiplier is not keyed in, the sales amount is calculated by multiplying by 1).
A sales process is performed for each product in the sales total memory 3 (normal sales processing means).

If it is determined in step ST5 that the product is a product targeted for a special sale plan, data set corresponding to the corresponding special sale plan code is read from the special sale master file 5 in step ST7. Then, in ST8, it is determined whether or not the chained special sale planning code exists in the setting data read from the special sale master file 5 (sale sale determining means).

Here, if a chain special sale plan code exists, another special sale plan to be discounted for the special sale plan, that is, a so-called chain special sale plan, is set.
As T9, the special sale plan sales data of the member master record stored in the record memory 32 is searched to determine whether or not the purchase history of the product sold in the chain special sale plan. Then, if the plan code of the chain sale plan and the corresponding final purchase date are included in the sale plan sales data, it is determined that there is a purchase history of the corresponding product. In contrast,
If the plan code of the chain sale plan and the corresponding final purchase date are not included in the sale plan sales data, it is determined that there is no purchase history of the corresponding product.

If it is determined in step ST9 that there is a purchase history of the merchandise sold in the chain sale plan, the process proceeds to step ST10 in which
The special sale unit price acquired in the process of T3 is discounted by the discount rate acquired in the process of ST7, and the calculated amount is recognized as the unit price of the sale product. Then, the process proceeds to ST12 to calculate the sales amount by multiplying the unit price by the sales points, and sales processing is performed on the sales points and the sales amount in the sales totaling memory of the RAM 13 for each product (special sale discount sales processing means).

On the other hand, if there is no chain special sale plan code in the setting data read from the special sale master file 5 in ST8, or if it is determined in ST9 that there is no purchase history of the specially sold product in the chain special sale plan, ST1
As 1, the unit price of the special sale acquired in the process of ST3 is recognized as the unit price of the sale product. Then, the process proceeds to ST12 to calculate the sales amount by multiplying the unit price by the number of sales points, and sales processing is performed on the sales points and sales amount in the sales totaling memory of the RAM 13 for each product (special sales processing means).

When the sales processing of the merchandise sales data is completed in ST12, it is determined in ST13 whether or not the merchandise to be sold is registered. If it is the registration of a product targeted for the special sale plan, the special plan sales data of the member master record stored in the record memory 32 is updated in ST14. That is, if the current special sale plan code does not exist in the special sale plan sales data, the current special sale plan code and the current date (the last purchase date) are added. Replace the purchase date with the current date. If it is the registration of a product not covered by the special sale plan, the process of ST14 is not performed. Above,
This product registration processing ends.

FIG. 11 shows the processing of the CPU 11 when the closing key of the keyboard 19 is input in the "registration" mode. That is, when the key input of the closing key is detected via the keyboard controller 20, the CPU 11 starts the closing key processing. First, the registered flag in the flag memory 34 is checked as ST1. If the registering flag has been reset to "0", this is an erroneous operation of declaring the registration to be closed without registering the merchandise of one transaction.

If the registering flag is set to "1" in ST1, since the registration of goods for one transaction has been declared, the usual registration closing processing such as change calculation and receipt printing is performed in ST2. Execute. When the registration closing process is completed, the registering flag is reset to "0" in ST3. Thereafter, as ST4, the member transaction flag in the flag memory 33 is checked. Here, if the member transaction flag has been reset to “0”, this is a transaction with a non-member, and the closing key processing ends.

If the member transaction flag is set to "1" in ST4, it is a transaction with the member, so
With reference to the local file of the special sale master file 5 as T5, the next special sale plan, that is, the chain special sale plan code set for the future special sale plan code whose sale start date is closest to the current date is acquired.

Next, as ST6, the special sales plan data of the member master record stored in the record memory 32 is searched to determine whether or not the chain special sales plan code acquired in the process of ST5 exists. If there is, a message is printed on the receipt informing the customer that there are more benefits in the next special sale plan as ST7. Then, this receipt is issued as ST8.

In ST6, if the corresponding special sale plan code does not exist in the special sale plan sales data of the member master record (the special sale plan code is set for the future special sale plan code whose sale start date is closest to the current date). If not, the process proceeds to ST8 and issues a receipt.

Next, the member master record stored in the record memory 32 is taken out, and a data transmission message including the member master record is created. Then, it controls the communication interface 15 to transmit this data transmission message to the store computer 1. Thereafter, the record memory 32 is cleared, and if the member transaction flag is reset to “0” in ST9, the closing key process ends.

The store computer 1 that has received the data transmission message overwrites the member master record in the received message with the member master file 6.

As described above, in the present embodiment, the unit price at the time of bargain sale of the product is stored in the single item master file 4 in which the normal unit price and the like are set and stored corresponding to the product code set for each product. A special sale unit price and an identification code of a special sale plan for which the product is a special sale target, that is, a so-called special sale plan code, are set and stored. In addition, a special sale master file 5 in which the special sale period and the like are set and stored in correspondence with the special sale plan code of each special sale plan, and other special sale plans that are discounted for the special sale plan, so-called chain special sale plans The plan code and the discount rate are selectively set and stored. Further, in the member master file 6 for setting and storing personal information such as the member name in accordance with the member code unique to each member set for each member, a special sale plan when the member purchases a special sale product. The code and the final sales date are updated and accumulated at any time as bargain sales data. And these master files 4,
5 and 6 are provided in the store computer 1, and local files of the single item master file 4 and the special sale master file 5 are provided in each POS terminal 3 connected to the store computer 1 via the communication line 2.

In the POS terminal 3,
The card data of the membership card on which the membership code is recorded is read by the card reader 28 or the keyboard 19
In the state where the member code is entered by the key operation and the member transaction is declared, if the product registration is performed by the scanning operation of the scanner 21 or the key operation of the keyboard 19, it is determined whether the registered product is a product targeted for bargain sale or not. Is determined from the information of the single item master file 4 and the special sale master file 5 (local file). Specifically, when a special sale plan code is set corresponding to the single item code of the registered product, and the current date is within the period of the special sale plan identified by the special sale plan code, it is determined that the product is a target of the special sale plan Otherwise, it is determined that the product is not targeted for sale planning.

Here, when it is determined that the registered product is a product not covered by the bargain sale plan, the registered product is processed for sale at a normal unit price. On the other hand, if the registered product is determined to be a product targeted for a special sale plan, it is determined from the information in the special sale master file 5 (local file) whether or not a chain special sale plan to be discounted is set for the special sale plan. Is determined.
Specifically, it is determined that a chain special sale plan is set when a chain special sale plan code is set corresponding to the corresponding special sale plan code, and when no chain special sale plan code is set, the chain special sale plan is set. It is determined that no plan is set.

Here, if it is determined that there is no chain sale plan set, the registered product is sold at the sale unit price. On the other hand, if it is determined that a chain sale plan has been set, it is determined based on the sale plan sales data in the member master file 6 whether this member has a history of purchasing products sold in the chain sale plan. Is determined. Specifically, if the special sale plan sales data corresponding to this member's member number includes the data of the special sale plan and the data of the last sale date, it is determined that there is a purchase history. It is determined that there is no history.

Here, when it is determined that there is no purchase history, the sales of the registered product are processed at the bargain price. On the other hand, when it is determined that there is no purchase history, the special sale unit price of the registered product is discounted at the discount rate of the chain sale plan, and sales processing is performed at the discounted unit price.

When a product purchased by a member customer is a product targeted for a special sale plan, the product purchase history of the special sale plan is added to the special sale plan sales data corresponding to the member customer in the member master file 5. At this time, if the product purchase history of the special sale plan has already been added, only the last sales date is updated.

The receipt issued to the member customer includes a next special sale plan, that is, a case where a chain special sale plan is set for a future special sale plan whose special sale start date is closest to the current date. Only when the merchandise subject to the chain sale plan has been purchased, a message is printed to notify the member customer that there are more benefits in the next sale plan.

For example, now, February 1, 2000 to 2
During the special sale plan “X2 special sale: special sale plan code = X02” with a special sale period of up to 9 days, this special sale plan “X
For the “2 special sale”, a special sale plan “X1 special sale: special sale plan code = X01” with a special sale period from January 1 to the same month 31, 2000 is set as a chain special sale plan (discount rate 10%). Also, for the next special sale project “X3 special sale: special sale plan code X03”, this special sale plan “X2
It is assumed that "sale" is set as a chain sale plan (see FIG. 3).

In this state, a member customer who has not purchased a product sold in the chain special sale plan "X1 special sale" can sell a special product "DDD" with a special sale unit price of 50 yen sold in the special sale plan "X2 special sale" this time. If two items are purchased, the product “DD”
"D" is processed for sale at a unit price of 50 yen. And FIG.
A receipt having the contents shown in (a) is printed and issued.

Also, a member who has purchased a product sold in the chain special sales plan "X1 special sale" receives the same product "DD".
If two items "D" are purchased, sales processing of the product "DDD" is performed at a price of 45 yen, which is a 10% discount from a special sale unit price of 50 yen. Then, a receipt having the contents shown in FIG. 8B is printed and issued. Incidentally, a message 80 printed at the lower stage of each receipt is a message for notifying the member customer that there is more privilege in the next special sale project.

As described above, according to the present embodiment, a customer who has purchased a product to be sold in a special sale plan will be asked to purchase a product to be sold in the next or subsequent special sale plan. In addition, it is possible to easily realize a chain sale system that sells at a price that is further reduced than the sale price. As a result, the purchase motivation of the member customers is promoted, an increase in the sales can be expected, and the customer retention is achieved.

Further, a message 80 is printed on the receipt to inform the member that there is more privilege in the next special sale plan, so that the customer can be strongly appealed for the service by the chain sale method.

[0056]

As described above in detail, according to the first aspect of the present invention, a customer who has purchased a product targeted for a special sale plan is not eligible for a special sale in the next or subsequent special sale plan. It is possible to provide a merchandise sales registration processing device that can easily process a chain special sales system in which a merchandise is purchased at a price that is further reduced from the special sale price.
