DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for registering sold goods, such as a cash register, a POS, or a toll scale. It relates to a data registration device.

[0002]

2. Description of the Related Art In a sales data registration device such as a POS, a technology for classifying and registering members and non-members includes:
Customer management systems are known. Here, whether or not the customer is a member is determined using a previously issued member card or the like. In this case, the non-member sets the normal price, and the member sets the member price lower than the normal price and has a lower price for a given product, and displays both prices on the display shelf. To provide membership services,
There is a method of discounting the total purchase amount of members.
Compared with the method, the method of (1) has a merit that the type of the target product is smaller and the sense of inexpensiveness for the product can be set larger, which is attractive and that the member can be easily secured.

[0003]

However, according to the above-described method, when a product registration operation (such as bar code reading) is performed, whether the price is the normal price or the member price is determined.
Before commencing product registration, it was necessary to input to the sales data registration device that the current transaction was a transaction with a member. Therefore, on the side of the store, a notice such as "Please submit the member card first!" Is displayed around the registration device, but not all members can execute it. Often submitted. in this way,
If your membership card is submitted after product registration has begun,
In order to change the regular price already registered to the member price,
There has been a problem that a correction operation or the like for a predetermined product must be performed, and processing for registration and settlement is unnecessarily prolonged.

The present invention has been made in view of this point, and it is possible to input that the user is a member even after product registration has already been started, and the registration / payment processing can be performed by the input. An object of the present invention is to provide a sales data registration device that does not prolong.

[0005]

According to the first aspect of the present invention,
In a sales data registration device that sets at least two types of unit prices for a given product, a normal unit price and a member unit price, selects a unit price depending on whether or not the user is a member, and calculates the purchase price, A corresponding normal amount area and a member amount area corresponding to the member unit price are provided for each registered product, and storage means for storing the product registration data of one transaction, and a transaction with the member during one transaction. If it is determined that there is, based on the data in the member amount area of the storage means, a control means for determining the registration amount of each registered product, and after the product registration operation of one transaction, the finalization of the product
And a receipt issuing means for printing a typical registration amount . The invention according to claim 2 assigns a product code to each product, sets at least two types of unit prices for a predetermined product, a normal unit price and a member unit price, and selects a unit price depending on whether or not the user is a member.

Display registered product data and subtotal amount. A touch panel 4 is provided on the clerk-side display 3. The touch panel 4 is used in a setting mode for registering preset keys, setting various files, and the like. Then, the registered preset keys are displayed on the clerk display 3 and can be operated on the touch panel 4. The keyboard 5 includes a numeric keypad for inputting numbers, a “subtotal key” for instructing the end of a registration operation in one transaction, and input / deposit of a deposit amount.
A “deposit / current total key” for instructing the change amount is provided. A card reader is provided in the magnetic card insertion slot 6a. When a predetermined membership card is passed through the magnetic card insertion slot 6a, the card reader transmits data (member code or the like) recorded on the membership card. Read.

FIG. 3 is a side view showing a schematic configuration example of a receipt / journal printer. In this figure, the cover (the cover of the printer unit) provided on the side surface of the apparatus is opened. The configuration shown in this figure is common to the master machine M and the satellite machine S. In this figure, the receipt printer unit 7b and the journal printer unit 7c both use a thermal printer. Each printer unit 7b, 7
In c, the thermal paper is pulled out from the roll and printing is performed by the platen roller and the thermal head. Then, the issued receipt is discharged to a receipt issuing port 7a (see FIG. 2), and the issued journal is taken up by a take-up roll. In addition, one motor for driving both platen rollers is shared by one motor, and is switched according to the rotation direction of the motor during driving. At this time, the receipt is issued first, so that the receipt can be quickly delivered to the customer, and then the journal is printed.

FIG. 4 is a block diagram showing an example of an electrical configuration of the sales data registration device according to the present embodiment. In this figure, parts corresponding to the respective parts in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted. The configuration shown in this figure is that of the master machine M, and the only difference is that the satellite machine S has a ROM (Read Only Memory) instead of the hard disk 9 shown in FIG. On the hard disk 9 of the master machine M, in addition to the control program of the CPU (Central Processing Unit) 8, a product file (see FIG. 5) and a customer file (not shown: customer number, name, address, record, member Is recorded. On the other hand, the ROM (not shown) of the satellite machine S stores only the control program. The RAM (random access memory) 10 has a working area for storing flags, registers, and the like, and a registration data area 1 (see FIG. 6) described later.

The key control section 11 controls the touch panel 4 and the keyboard 5. Barcode scanner 12
Reads the bar code of the product. The communication unit 13 performs communication with another POS terminal (the satellite machine S when the present apparatus is the master apparatus M, and the master apparatus M when the present apparatus is the satellite apparatus S). The configuration of the receipt / journal printer 7 is as shown in FIG. The card reader 6 reads a membership card (magnetic card).

FIG. 5 is an explanatory diagram showing a configuration example of a product file according to the present embodiment. As described above, the product file is provided in the hard disk 9 of the master machine M, and its contents can be displayed on the clerk-side display 3 and can be set using the touch panel 4 and the keyboard 5. As shown in FIG. 5, the product file includes, for each product,
The product code, product name, normal unit price, member unit price and the like are stored. Here, the member unit price is a unit price set only for a product that only a member can buy cheaper than usual. When the member unit price is “0”, it is assumed that the member unit price is not set.

FIG. 6 is an explanatory diagram showing a configuration example of the registration data area 1 according to the present embodiment. As described above, the registration data area 1 is provided in the RAM 10 (regardless of the master machine M or the satellite machine S). As shown in FIG. 6, the registration data area 1 stores, for each product registered in one transaction, a product code, a normal amount, a member amount, a sales number, a product name, etc. The data required for updating is stored. Here, the normal price is a value obtained by multiplying the normal unit price set in the product file (see FIG. 5) by the number of sales.
On the other hand, the member amount is a value obtained by multiplying the sales amount by the member amount set in the product file. Therefore, for a product for which a member unit price is not set in the product file, that is, for a product for which the member unit price is set to “0”, the member amount is “0”.

Next, the operation of the sales data registration device having the above configuration will be described. FIG. 7 is a flowchart illustrating an operation example in one transaction of the sales data registration device (master device M) according to the present embodiment. When one transaction is started by the operator performing a predetermined operation, the process proceeds to step SA1. In step SA1, the member flag provided in the working area of the RAM 10 and the registration data area 1 are cleared,
Proceed to step SA2.

In step SA2, it is determined whether or not a product code has been input. Here, the product code is input, for example, by reading a barcode printed on the product by the barcode scanner 12, or by operating a corresponding preset key. If the result of this determination is "NO", the flow proceeds to step SA3.

At step SA3, it is determined whether or not the card reader 6 has read the membership card. If this determination is "YES", the flow proceeds to step SA4. In step SA4, it is determined whether or not the member code of the member card read in step SA3 is set in the customer file. If the device that executes this flowchart is the satellite device S, the member code is transmitted to the master device M by communication and an inquiry is made. If the result of this determination is "NO", then step SA
Returning to step 2, if the determination is "YES", the flow proceeds to step SA5. In step SA5, a member flag is set, and the flow returns to step SA2. On the other hand, step SA3
Is "NO", the process proceeds to Step SA6. In step SA6, other processing not directly related to the present invention is performed, and the process returns to step SA2.

On the other hand, if the result of determination at step SA2 is "YE
In the case of "S", the process proceeds to step SA7. Step SA
At 7, the corresponding product data is called from the product file (see FIG. 5) based on the product code input at step SA2, and the process proceeds to step SA8. If the device that executes this flowchart is the satellite device S, the product code is transmitted to the master device M by communication, and the corresponding product data is received.

At step SA8, the merchandise data called at step SA7 is written in each column of the registration data area 1, and the process proceeds to step SA9. At this time, the multiplication value of the normal unit price and the sales number of the product data called in step SA7 is written in the normal amount column of the registration data area 1, and
The multiplication value of the member unit price and the sales number in the product data called in step SA7 is written.

In step SA9, it is determined whether or not the registration operation of all the products has been completed by referring to whether or not the subtotal key has been pressed. Key). If the determination is "NO", the flow returns to step SA2 to continue the registration operation, and if the determination is "YES", the flow proceeds to step SA10.

At step SA10, it is determined whether or not the member flag is set. The result of this determination is "N
In the case of "O", it is determined that the transaction is with a non-member, and the process proceeds to Step SA11. In step SA11, all the amounts in the ordinary amount column of the registered data area 1 are added, and the process proceeds to step SA12. At Step SA12, Step SA
The added value obtained in step 11 is displayed on the customer-side display 2 and the clerk-side display 3 as the total amount of this transaction.
Proceed to 3. In step SA13, when the operator inputs a deposit amount by key, the change amount is displayed on the customer display 2 and the clerk display 3, and the process proceeds to step SA14.

In step SA14, receipt printing and journal printing are performed, and the flow advances to step SA15. For these printings, first, the product name and normal amount of each product in the registration data area 1, the total amount obtained in step SA11, and the like are converted into print data, and receipt printing is performed first. Next, in order to save paper, print data for journal printing in which characters are made smaller is created for each of the data (product name, normal amount, total amount, and the like), and journal printing is performed. In step SA15, after the result is updated, checkout for one customer, that is, one transaction is completed. Here, as the update of the results, for example, the product code of the registration data area 1, the normal amount,
There is a performance update of the merchandise file performed based on the sales quantity, and a performance update of the sales amount at the store level based on the total amount obtained in step SA11. If the device that executes this flowchart is the satellite device S, the actual data is transmitted to the master device M by communication.

On the other hand, if the result of determination in step SA10 is "Y
In the case of "ES", it is determined that the transaction is with a member, and the process proceeds to Step SA16. In step SA16, the subroutine shown in FIG. 8 is called, and the subroutine is operated based on the subroutine to calculate the total amount for the member. Then, when the process returns from the subroutine shown in FIG. 8, the process proceeds to step SA17. The process of this step will be described later in detail with reference to FIG.

In step SA17, step SA16
Is displayed on the customer-side display 2 and the clerk-side display 3, and the process proceeds to step SA18. Step S
At A18, when the operator key-in the deposit amount,
The change amount is displayed on the customer-side display 2 and the clerk-side display 3, and the process proceeds to step SA19. In step SA19, receipt printing and journal printing are performed by the same operation as step SA14, and the flow advances to step SA20. However,
Here, for each product in the registration data area 1, the printed amount is a normal amount if the membership amount of the product is “0”, and if the membership amount of the product is other than “0”, the membership amount is And

At Step SA20, Step SA15
After the results are updated by the same operation as described above, checkout for one customer, that is, one transaction is completed. However, here, for each product in the registration data area 1,
The amount used for updating is the normal amount if the membership amount of the product is “0”, and the member amount if the membership amount of the product is other than “0”.

Next, the details of step SA16 will be described. FIG. 8 is a flowchart illustrating an operation example of step SA16 (see FIG. 7). In step SA16, when the subroutine shown in FIG.
After clearing the total amount of money secured in the predetermined area of No. 10 to “0” and setting the pointer to the product to be added to the first product in the registration data area 1, the process proceeds to step SB1.
In step SB1, it is determined whether or not the membership amount of the product pointed to by the pointer is "0" in the registration data area 1. If the result of this determination is "YES", the flow proceeds to step SB2. In step SB2, in the registration data area 1, the data of the normal amount of the product indicated by the pointer is added to the total amount, and the process proceeds to step SB4.

On the other hand, if the result of the determination in step SB1 is "N
If "O", the process proceeds to Step SB3. Step SB
In 3, in the registration data area 1, the data of the membership amount of the product pointed to by the pointer is added to the total amount,
Proceed to step SB4. In step SB4, it is determined whether or not the pointer points to the last product in the registered data area 1 (that is, whether or not the addition process has been performed for all the products in the registered data area 1). If the result of this determination is "NO", the pointer is moved to the next product, and the process returns to step SB1. On the other hand, if the result of this determination is "YES", the process returns to the step of calling this subroutine (step SA16: see FIG. 7).

§2. Second Embodiment Next, a second embodiment of the present invention will be described. Second
The configuration of the sales data registration device according to the embodiment is basically the same as the configuration of the sales data registration device according to the first embodiment. However, in the second embodiment, a registered data area 2 shown in FIG. 9 is used instead of the registered data area 1 of the first embodiment.

FIG. 9 is an explanatory diagram showing a configuration example of the registration data area 2 according to the present embodiment. Registration data area 2
Are provided in the RAM 10 similarly to the registration data area 1. As shown in FIG. 9, the registration data area 2 stores a product code, an amount, a sales number, a product name, a member product flag, and the like for each product registered in one transaction. Here, the member product flag is a flag indicating whether or not a member unit price is set for the product in the product file (see FIG. 5), and “1” indicates that the member unit price is set. “0” indicates that the member unit price is not set.

In the present embodiment, reading of the member card is always accepted even after the commencement of product registration, and if it is determined during the product registration that the current transaction is a transaction with a member, immediately
The contents of the registration data area 2 are shown in FIG.
Change to (b). That is, in FIG. 9, (a) shows a configuration example of the registration data area 2 before the above-described determination,
(B) shows an example of the configuration of the registration data area 2 after the above-described determination. Accordingly, the value in the amount column shown in FIG. 9A is the amount calculated as a transaction with a non-member customer (that is, the product of the normal unit price and the number of sales), and FIG.
Is the amount calculated as a transaction with the member (that is, for a product whose member product flag is "1", the amount changed to a product of the unit price of the member and the number of sales).
It has become.

Next, the operation of the sales data registration device having the above configuration will be described. 10 and 11 are flowcharts showing an operation example in one transaction of the sales data registration device (master machine M) according to the present embodiment. When the operator performs a predetermined operation and one transaction is started, step S
Proceed to C1. In step SC1, the member flag provided in the working area of the RAM 10 and the registration data area 2 are cleared, and the process proceeds to step SC2.

At step SC2, it is determined whether or not a product code has been input by the same operation as at step SA2. If the result of this determination is "YES", the flow proceeds to step SC3. At Step SC3, Step SA
According to the same operation as in step 7, the corresponding product data is called from the product file (see FIG. 5) based on the product code input in step SC2, and the process proceeds to step SC4.
In step SC4, it is determined whether or not the member flag is set. If the result of this determination is "YES", it is determined that the transaction is with a member, and the flow proceeds to step SC5.

In step SC5, the product data called in step SC3 is written in each column of the registration data area 2, and the flow advances to step SC7. Here, in the amount column,
If the unit price of the called product data is other than "0", a value obtained by multiplying the unit price of the member and the number of sales is written. If the unit price of the member is "0", the normal unit price and the sales number of the called product data are written. Write the value multiplied by. On the other hand, step SC
If the determination result of No. 4 is “NO”, it is determined that the transaction is with a non-member, and the process proceeds to Step SC6. Step SC6
Then, the product data called in step SC3 is written in each column of the registration data area 2, and the process proceeds to step SC7. Here, a value obtained by multiplying the normal unit price of the called product data by the sales number is written in the amount column. If the unit price of the called product data is other than “0”, the member product flag in the registration data area 2 is set. By the processing in step SC6, the registration data area 2 is written, for example, as shown in FIG.

In step SC7, it is determined whether or not the operation of registering all the commodities has been completed by the same operation as in step SA9. If this determination is "NO", the flow returns to step SC2 to continue the registration operation.

On the other hand, if the result of the determination in step SC2 is "N
In the case of “O”, the process proceeds to step SC8 (see FIG. 11). In step SC8, it is determined whether the card reader 6 has read the membership card. If the result of this determination is "YES", the flow proceeds to step SC10.
In step SC10, it is determined whether or not the member code of the member card read in step SC8 is set in the customer file by the same operation as step SA4. If the result of this determination is "NO", the flow proceeds to step SC
Returning to step 2, if the determination is "YES", the flow proceeds to step SC11.

In step SC11, a member flag is set, and a pointer to a product whose price is to be changed is set to the first product in the registration data area 2, and then the process proceeds to step S11.
Proceed to C12. In step SC12, it is determined whether or not the member product flag of the product indicated by the pointer is set in the registration data area 2. With this determination, it is not necessary to perform useless processing on a product for which it is not necessary to change the amount of money (that is, a product for which the member unit price is not set). If the result of this determination is "YES",
It is determined that the item is a product for which the member unit price is set, and the process proceeds to step SC13.

In step SC13, the product data is called again by the same operation as step SC3, and the flow advances to step SC14. In step SC14, in the registered data area 2, the price column of the product pointed to by the pointer is changed, and the process proceeds to step SC15. Here, the update is performed in the product data called in step SC13.
This is performed by writing a value obtained by multiplying the unit price of the member and the number of sales in the above-mentioned amount column.

On the other hand, if the result of the determination in step SC12 is "N
Also in the case of "O", the process proceeds to step SC15. Step S
At C15, it is determined whether or not the pointer points to the last product in the registered data area 2 (that is, whether or not the determination process in step SC12 has been performed for all the products in the registered data area 2). If the result of this determination is "NO"
In the case of, the pointer is moved to the next product, and the process returns to step SC12. On the other hand, if the determination result is “YES”
In this case, the process returns to step SC2.

By the processing in steps SC12 to SC15 described above, the registration data area 2 becomes, for example, as shown in FIG.
Is changed as shown in FIG. 9B. On the other hand, if the decision result in the step SC8 is "NO",
Proceed to step SC9. In step SC9, other processing not directly related to the present invention is performed, and the process returns to step SC2.

On the other hand, if the result of the judgment in step SC7 is "YE
In the case of "S", the flow proceeds to step SC16. Step S
At C16, all the amounts in the amount column of the registration data area 2 are added, and the process proceeds to Step SC17. In step SC17, the added value obtained in step SC16 is displayed on the customer display 2 and the clerk display 3 as the total amount of the transaction, and the process proceeds to step SC18. In step SC18,
When the operator inputs the deposit amount by key, the change amount is displayed on the customer side display 2 and the clerk side display 3, and step SC19.
Proceed to.

At Step SC19, Step SA14
Receipt printing and journal printing are performed by the same operation as described above, and the flow advances to step SC20. Here, the product name and price of each product in the registration data area 2, the total price obtained in step SC16, and the like are converted into print data and printed. In Step SC20, Step SA15
After the results are updated by the same operation as described above, checkout for one customer, that is, one transaction is completed. Here, the performance update of the product file is performed based on the product code, the amount, and the number of sales in the registration data area 2, and the performance update such as the sales amount at the store level is performed based on the total amount obtained in step SC16. .

§3. Supplement Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to the embodiment, and there may be a design change or the like without departing from the gist of the present invention. Even this is included in the present invention. For example, in the above-described embodiment, an example is described in which two types of unit prices such as a normal unit price and a member unit price are set in a product file (see FIG. 5).
The present invention is not limited to this, and any data may be set as long as the price of the product differs depending on whether or not the user is a member. As one example, a unit price of only one of the normal unit price and the member unit price and a difference (or a discount rate or the like) with respect to the unit price may be set.
Also, a plurality of member unit prices may be set according to the magnitude of the cumulative purchase amount of the member.

Further, in the above-described embodiment, the member unit price is set to “0” for the product for which the member unit price is not set, but the member unit price for the product for which the member unit price is not set is also set to “0”. It may be set to the same value as the normal unit price.
However, in this case, in the second embodiment, it is necessary to determine whether the member unit price is set by determining whether the normal unit price and the member unit price match. In the above-described embodiment, the magnetic card is used as the member card. However, the present invention is not limited to this. The member code is read to determine whether the user is a member, such as an IC card or a card on which a barcode is printed. Anything can be used as long as it is possible.

In the above-described embodiment, an example of application to a POS terminal device has been described. However, the present invention is not limited to this, and the present invention can be applied to a charge scale provided with a weighing device. In this case, the normal unit price and the member unit price stored in the product file are unit prices per unit weight (for example, 100 g). Further, the present invention is also applicable to a system in which a store controller for managing a database is connected instead of the master machine. In the embodiment described above,
A thermal printer was used as a receipt / journal printer, but the present invention is not limited to this. After the code input for all products in one transaction is completed, that is, after the registration operation is completed, the final price of the products is printed together. Any printer can be used as long as it can issue a receipt at high speed.

In the above-described embodiment, the input of the transaction with the member is possible until the registration of all the commodities is completed. However, even after the registration is completed, the input (transaction with the member) can be performed. Is entered), the registered amount can be determined, and if the total amount can be displayed, until the closing key operation for closing the transaction such as the deposit current total key is performed This input (input of a transaction with a member) may be performed.

[0046]

As described above, according to the present invention, if a transaction is being made with a member during a single transaction, a predetermined product can be purchased without any special operation. You can register at the member price. Therefore, there is no restriction on the timing of the input, and a good impression can be given to the member. Further, according to the present invention, it is input that the transaction is with the member after the product registration operation, and even if there is a product whose registration amount changes,
There is no need to correct the printed content of the receipt. as a result,
Receipts are easy to see and receipt paper is not wasted. According to the third aspect of the present invention, the above-described effects can be obtained even with a toll scale.
