DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a POS (Point of Point)
Sales: point-of-sale management) It relates to a product sales registration data processing device such as a terminal.

[0002]

2. Description of the Related Art Generally, a shopper pays for a commodity using cash or a credit card when purchasing the product. However, some shops use a ticket having the same value as cash, that is, a so-called cash voucher. Some have made it possible. For example, many department stores handle cash vouchers called gift certificates, sake shops handle cash vouchers called beer tickets, and bookstores handle cash vouchers called book coupons. Recently, local governments have issued gold vouchers called regional promotion vouchers, which are used instead of cash at various stores.

Further, some stores issue their own vouchers in the name of customers such as discount coupons (coupon vouchers) and provide services that enable payment of purchased products with the vouchers. .

By the way, in such a service, change is not paid even if a cash voucher having a face value larger than the payment amount is used, and the service is invalid. As a reason, for example, if it is assumed that change is paid in cash, depending on the customer, it is possible to obtain a large amount of cash as change by paying a small purchase with a large cash voucher. If this is the case, the initial purpose of the voucher (for example, use at a issuing store for a gift certificate, purchase of beer for a beer ticket, etc.) cannot be achieved in many cases.

[0005] However, in such a service in which change is not paid, a feeling of loss remains for the shopper, which may adversely affect the service of the shop.

Therefore, in recent years, when a change is generated due to the use of a cash voucher whose face value is larger than the payment amount for the purchased product, a POS which issues a voucher corresponding to the change is issued. A product sales registration data processing device such as a terminal has been considered.

[0007]

However, since the above-described cash voucher equivalent to change is easily issued by a receipt printer provided in a POS terminal or the like that issues a receipt or the like, it is comparatively difficult. There was a problem that it was easily forged.

[0008] It is an object of the present invention to provide a merchandise sales registration data processing device capable of issuing a fishing-equivalent gift certificate that can prevent forgery and the like.

[0009]

According to the first aspect of the present invention,
If the face value of the voucher used for payment of the total sales amount based on the sales of the product is larger than the total sales amount and a change occurs, a fishing equivalent gift voucher with the amount equivalent to the change as the face value And a management number assigning means for printing a management number unique to the fishing-equivalent gift certificate to be printed and issued.

[0010] Accordingly, a fishing-equivalent product which is printed and issued as a par value when the par value of the cash voucher used for payment of the total sales amount based on the sales of the product is larger than the total sales value. A unique management number is printed on the ticket.

According to a second aspect of the present invention, there is provided a merchandise sales registration data processing apparatus according to the first aspect, wherein a management number acquiring means for acquiring the management number printed on the fishing-equivalent gift certificate used for payment. Use / unused identification means for identifying whether or not the fishing-equivalent gift certificate is unused based on the management number acquired by the management number acquisition means, and the acquired management number is printed. Use permitting means for permitting payment of the fishing equivalent gift certificate when the fishing equivalent gift certificate is identified as unused by the used / unused identifying means.

Therefore, the management number printed on the fishing-equivalent gift certificate used for payment is acquired by the management-number acquiring means, and based on the acquired management number, whether the fishing-equivalent gift certificate is unused or not. Only when the use / unused identification means is identified by the use / unused identification means, and the acquired management number is printed and the fishing equivalent gift certificate is identified as unused, payment by the fishing equivalent gift certificate can be made. Allowed. As a result, even if a fishing equivalent gift certificate is copied or forged and used, if the original fishing equivalent gift certificate is already used, the copied or counterfeit fishing equivalent product is used. It becomes possible to invalidate tickets.

According to a third aspect of the present invention, in the merchandise sales registration data processing apparatus according to the second aspect, the management number obtaining means reads the management number printed as a bar code on the fishing equivalent gift certificate. It is read by the device to obtain the management number.

Therefore, the input of the management number becomes reliable and easy.

The invention described in claim 4 is the first to third aspects of the present invention.
In the merchandise sales registration data processing device according to any one of the above, if the par value of the fishing equivalent gift certificate is larger than the total sales amount, a par value corresponding to the change and a unique The fishing-equivalent gift certificate printed with the management number is issued again.

Therefore, when a change is generated again by using a fishing-equivalent gift certificate for payment, a secondary fishing-equivalent product on which a denomination corresponding to the change and a unique management number are printed. By issuing the ticket, it becomes possible to use up the face value of the cash voucher originally used for payment until the change amount is exhausted, so that the service to the customer is further improved.

In the POS terminal 1 after activation, an operation mode is selected according to the switching position of the mode key 5. That is, the microcomputer 11 sets the operation mode of the POS terminal 1 to a registration mode, a setting mode, a payment mode, an inspection mode, or the like according to an output signal generated by a switching position of the mode key 5. In the present embodiment, the description of the same processing as that performed by the conventional POS terminal in each mode is omitted. Next, the flow of sales processing in the registration mode, which is a feature of the present embodiment, will be described below.

FIG. 5 is a flowchart schematically showing the flow of the sales process in the registration mode. The sales process is executed on condition that the mode is set to the registration mode by the switching operation of the mode key 5. In this sales process, first, for the sales product, the process waits until the bar code scanner 10 reads the product code, inputs the product code using the number key 4a, inputs the sales quantity using the number key 4a, and the like (step S1). . If it is determined that the barcode scanner 10 has read the product code, entered the product code using the numeric key 4a, and entered the sales quantity using the numeric key 4a (Y in step S1), the sales registration is performed in step S2. The processing is executed. In this sales registration process, sales data based on the product name, unit price, and department code obtained by searching the product master file based on the input product code is stored in a sales buffer, and transaction information such as the unit price is stored. The information is displayed on the display 8 or the customer display unit 9.

The processing in steps S1 and S2 is performed by subtotal key 4
e is determined to have been operated (Y in step S3).
Alternatively, the process is repeated until it is determined that the deposit / current total key 4d has been operated (Y in step S4).

When it is determined that the subtotal key 4e has been operated (Y in step S3), the total sales amount including the consumption tax and the like is calculated and displayed on the display 8 and the customer side display unit 9 (step S5).

Subsequently, in a state where the total sales amount is displayed on the display 8 or the customer side display unit 9, the process stands by for input of the payment amount by the number key 4 a when the customer hands over the payment amount to the operator. (Step S6). When it is determined that the numeric key 4a has been operated (step S6).
(Y), the number corresponding to any one of the operated numeric keys 4a from "0" to "9" is sequentially stored in the RAM 15 as the payment amount (step S7). The processing of steps S6 to S7 is repeated until it is determined that the deposit / current total key 4d has been operated (Y in step S10). If the numeric key 4a is operated a plurality of times,
The number previously operated and stored becomes the upper digit.
For example, if the numeric key 4a is operated in the order of "1", "0", "0", the payment price is 100 yen.

In addition, when a customer has handed a voucher such as a gift certificate, a coupon, a regional promotion ticket, or the like to the operator as a payment price, or a customer has provided a gift certificate, a coupon ticket, or a region as a payment price to the operator. When a cash voucher such as a promotion voucher and cash are handed together, a coupon key is used when inputting the payment price with the numeric key 4a (before the deposit / current total key 4d is operated in step S10). 4b is operated. Thus, when it is determined that the coupon key 4b has been operated (before the deposit / current total key 4d is operated in step S10) at the time of inputting the payment price with the numeric key 4a (Y in step S8). It is determined that the payment amount stored in the RAM 15 is due to a voucher such as a gift certificate, a coupon ticket, or a regional promotion ticket, and the process proceeds to step S11.
Execute the voucher receiving process. In this voucher receiving process, processing is performed such as storing the amount paid by the voucher in the sales file separately from the amount paid by cash.

Further, when a customer issues a store-issued coupon C as a payment to the operator, or when a customer delivers a store-issued coupon C and cash together as a payment to the operator. Is a coupon key 4c issued by the store when inputting the payment amount with the numeric key 4a (before the deposit / current total key 4d is operated in step S10).
Is operated. When the payment price is input by the numeric key 4a (before the deposit / current total key 4d is operated in step S10), when it is determined that the store issued coupon key 4c is operated (step S9). (Y), the process proceeds to step S12, and waits for the acquisition of the issue number and the expiration date given for each store issued coupon C. The issue number is
The barcode is obtained by reading the barcode b printed on the coupon C issued by the store with the barcode scanner 10. Here, the function of the management number acquisition means is executed.
In addition, since the par value is also stored in the barcode b, when the price is paid by the coupon C issued by the store, it is not necessary to input the payment price with the numeric key 4a. As described above, the issue number, expiration date, par value, etc. are printed as bar codes, so that each entry is secure,
And it can be easily performed.

When the issuance number and expiration date of the coupon C issued by the store are acquired (Y in step S12), step S1 is executed.
Proceeding to step 3, it is determined whether or not the store-issued coupon C is valid based on the issue number and the expiration date acquired in step S12. Here, whether or not the store-issued coupon C is valid is determined by whether or not the acquired issue number matches the issue number stored in the issue number file, and whether or not the date counted by the timer T is valid. Judgment is made based on whether it is within the time limit. That is, since the issue number stored in the issue number file is the issue number of the unused store issue coupon C, if the acquired issue number matches the issue number stored in the issue number file, The numbered store-issued coupon C is identified as unused. Here, the function of the used / unused identification means is executed. Only when the acquired issue number matches the issue number stored in the issue number file and the date measured by the timer T is within the acquired expiration date (Y in step S13), the store is issued. It is determined that the issued coupon C is valid, and the process proceeds to step S14.

In step S14, an issue number matching the issue number stored in the issue number file is deleted from the issue number file. Therefore, even when the store-issued coupon C is copied or counterfeited and used, if the original store-issued coupon C has already been used and the issue number has been deleted from the issue number file, Means that the copied or counterfeit store-issued coupon C becomes invalid.

When the acquired issue number does not match the issue number stored in the issue number file, or when the date measured by the timer T is not within the acquired expiration date, that is, the coupon issued by the store If it is determined that C is invalid (N in step S13), error processing is performed. In the error processing, if the acquired issue number matches the issue number stored in the issue number file, even if the date measured by the timer T is not within the acquired expiration date, The issue number matching the issue number stored in the issue number file is deleted from the issue number file.

It is determined that the store-issued coupon C is valid (Y in step S13), and after the issue number is deleted from the issue number file (step S14), the process proceeds to step S11 to execute a cash voucher receiving process. Here, the function of the use permission unit is executed.

When it is determined in step S4 that the deposit / current total key 4d has been operated (Y in step S4), or in step S10, the deposit / current total key 4d has been operated.
When it is determined that d has been operated (Y in step S10), the process proceeds to step S15, and the closing process is executed.

FIG. 6 is a flowchart schematically showing the flow of the closing process. As shown in FIG. 6, in the closing process, first, the total value of the face value of the voucher such as the gift certificate, coupon ticket, and regional promotion ticket that has been subjected to the note receiving process in step S11 and the face value of the coupon C issued by the store are calculated. Then, it is determined whether or not it is greater than the total sales amount calculated in step S5 (step S21).

The sum of the face value of a gift certificate, a coupon, a regional promotion ticket, etc. and the face value of the coupon C issued by the store is:
If it is determined that the change is greater than the total sales amount (Y in step S21), a change is generated by payment of a cash voucher or the like. It is printed by the printer 22 and issued from the receipt issuing port 6. As shown in FIG. 3 described above, the amount corresponding to the change is printed on the store-issued coupon C as a denomination a, and the denomination, a unique issue number assigned to each store-issued coupon, an issue date, The bar code b in which the expiration date and the like are coded is printed. Here, the function of the management number assigning means is executed.

In the subsequent step S23, the issue number of the store-issued coupon C issued in step S22 is stored in the issue number file.

Thereafter, when it is determined that the sum of the face value of the vouchers such as gift certificates, coupon tickets, and regional promotion tickets and the face value of the coupon C issued by the store is smaller than the total sales amount (N in step S21). Similarly, in step S24, the sales data and the like stored in the sales buffer of the RAM 15 are also used to calculate, for example, the sales quantity, sales amount, and number of customers for each product, and the calculation results are stored in the sales file. You.

In the receipt issuing process of step S25, the transaction contents stored in the print buffer are printed by the thermal printer 22 and issued from the receipt issuing port 6 as a receipt.

Here, the store issuance where the amount equivalent to the change when the par value of the voucher used for payment of the total sales amount based on the sales of the product is larger than the total sales amount is printed and issued as the par value. The issue number is printed on coupon C. In addition, an issue number printed on the store-issued coupon C used for payment is acquired, and whether or not the store-issued coupon C is unused is determined based on the acquired issue number. Identified by means,
Only when it is determined that the store-issued coupon C on which the acquired issue number is printed is unused, payment by the store-issued coupon C is permitted. Thus, even when the store-issued coupon C is copied or forged and used, if the original store-issued coupon C is already used, the copied or forged store-issued coupon C is used. Since C can be invalidated, forgery and the like can be prevented.

If a change is made again using the store issued coupon C for payment, a secondary store issued coupon C printed with a denomination and an issue number corresponding to the change is issued. Printed and issued. As a result, the face value of the cash voucher originally used for payment can be used up until the change amount runs out, so that the service to the customer can be further improved.

In the present embodiment, only the issue number of the unused store issued coupon C is stored in the issue number file. However, the present invention is not limited to this. A flag may be set for the issue number of the store-issued coupon C used and stored in the number file, or only the issue number of the used store-issued coupon C may be stored in the issue number file. May be. In any case, it is possible to identify whether or not the store issued coupon C is unused.

Further, in this embodiment, whether or not the store-issued coupon C is valid is determined based on the issue number and the expiration date. However, the present invention is not limited to this. It may be determined whether or not C is valid.
