The discount coupon C is printed with a text T indicating the discount amount and a bar code B obtained by transcoding the product code of the target product, and the discount amount can be grasped visually. Similarly, it can be read by a barcode reader (not shown) or the like. In addition, the discount coupon C of this embodiment shall be formed as a label which has an adhesion layer in the back surface. Thereby, since it can affix on the goods used as object, loss of a coupon, mistakes, etc. can be prevented.

  Next, the control configuration of the store server 4 and the coupon issuing device 2 will be described with reference to the control block diagram of the coupon issuing system 1 in FIG. First, the store server 4 has a hardware configuration mounted on a general personal computer in addition to the control unit 21, the storage unit 22, and the communication unit 23. The control unit 21 includes a CPU (Central Processing Unit) 25, a RAM (Random Access Memory) 26, and a ROM (Read Only Memory) 27, and controls the store server 4 as a whole. The ROM 27 stores a control program and control data for the CPU 25 to execute various processes. The RAM 26 is used as a work area when the CPU 25 executes various processes.

  The storage unit 22 has a customer information database 28. The customer information database 28 includes general customer information such as the name, address, membership number, purchase history, service points, etc. of the customer who became a member of the store and a weighting amount based on the purchase history (hereinafter referred to as “customer weighting amount”). ") Is recorded. The customer weighting amount is a so-called customer rank, and is used as a parameter when calculating the discount amount of the product. For example, a high weighting amount is set for a customer with a large number of purchases (store visits) (that is, a customer with a high customer rank). As a result, it is possible to provide services to regular customers such as a higher discount amount than normal customers (as compared to general customers), so it is possible to lock in customers and thus increase the rate of attracting customers. Can do.

  The purchase history may be the number of purchases (number of visits) or the purchase amount. Further, the weighting amount may be set based on all the purchase histories up to now, or the weighting amount may be set based on a purchase history (a purchase history for one month last month, etc.) divided into periods.

  The communication unit 23 communicates with the coupon issuing device 2 via the access point 3. When receiving the customer information acquisition request from the coupon issuing device 2, the control unit 21 reads the corresponding customer information (customer weighting amount) from the customer information database 28 based on the membership number included in the customer information acquisition request. It transmits to the coupon issue apparatus 2.

  The coupon issuing device 2 includes a CPU 31, a RAM 32, a ROM 33, a flash ROM 34, an operation unit 11, a display unit 12, a coupon issuing unit 13, a reading unit 14, a communication unit 35, and a time measuring unit 36, and is connected via a bus 37. ing. The RAM 32 is used as a work area when the CPU 31 executes various processes.

  The ROM 33 stores a control program and control data for the CPU 31 to execute various processes. Specifically, a discount amount calculation program (discount amount calculation unit) is included. This discount calculation program is based on the remaining time from the current time to the closing time, the product information (product name, product code, product category, etc.) of the product to be discounted and the customer information of the customer who purchases the product. The discount amount of the target product is calculated (details will be described later).

  The flash ROM 34 has a closing time storage unit 41, a discount target product storage unit 42, and a discount information storage unit 43. The closing time storage unit 41 stores the closing time of the store. As for the closing time, the store clerk can set the time corresponding to each store by operating the operation unit 11 (the time setting key 17 and the numeric key group 11a).

  FIG. 4 is a diagram illustrating a change in the discount amount according to the remaining time from the current time to the closing time for each product category. The discount target product storage unit 42 stores a product code of a product to be discounted and a weighting amount for each product code (each product) (hereinafter referred to as “product weighting amount”) in association with each other. This product weighting amount is used as a parameter when calculating the discount amount of the product to be discounted. For example, when the target product is a special sale product, the discount amount is set higher than usual. It can be set high, and a discount amount suitable for each product can be calculated.

  The discount information storage unit 43 stores a discount amount over time for each product category (vegetables, meat, fresh fish, etc.). Specifically, for each product category, the discount amount is changed with the remaining time from the current time to the closing time, and as the remaining time decreases (as the closing time approaches), the discount amount gradually increases. It is set to be high (large) (that is, the relationship between the remaining time and the discount amount is a quadratic curve) (see FIG. 4). In the present embodiment, the discount amount associated with the remaining time is set for each product category. However, the present invention is not limited to this, and can be set for each product code (for each product).

  Further, the discount information storage unit 43 stores a maximum discount amount corresponding to each product category (hereinafter referred to as “maximum discount amount”). This maximum discount amount is set as the upper limit of the discount amount calculated in consideration of the various elements described above. As a result, for example, the discount amount (discount amount) is higher than the normal selling price, or the discount amount (discount rate) is less than the profit for a product that expects a predetermined profit. It is possible to prevent an inappropriate discount amount.

  In the above description, “vegetables”, “meat”, and “fresh fish” are illustrated as product categories, but this is an example. For example, these are regarded as “fresh food” as one product category, It is also possible to set a discount amount for this product category (fresh food).

  The timer 36 is an RTC (Real Time Clock) built in the coupon issuing device 2 and counts the date and time. In the present embodiment, it is used to acquire the current time (current date and time) for obtaining the remaining time until the closing time.

  The communication unit 35 communicates with the store server 4 via the access point 3. When the membership card is read by the reading unit 14, the CPU 31 controls the communication unit 35 to issue a customer information acquisition request for acquiring customer information corresponding to the membership number of the membership card via the access point 3. Send to server 4. Moreover, the result (corresponding customer weighting amount) for the customer information acquisition request is received from the store server 4.

  With these configurations, the coupon issuing device 2 reads the membership card and the product label with the reading unit 14, and acquires customer information (customer weighting amount) and product information (product code, product category). And the discount amount with respect to the said goods at this time is calculated from this customer information and goods information. Thereafter, a discount coupon C on which the discount amount is printed is issued.

  Next, a procedure for issuing the discount coupon C will be described with reference to a flowchart showing a procedure for issuing the discount coupon C in FIG. Here, it is assumed that the customer issues a discount coupon C. First, when the customer presses the read key 15 to read the target product label, the coupon issuing device 2 reads the target product information (step S01). Next, the coupon issuing device 2 determines whether or not the product is a discount target product. That is, it is determined whether or not the product code included in the read product information is the product code recorded in the discount target product storage unit 42 (step S02).

  If the product code is not a discount target product code (step S03; No), the coupon issuing device 2 displays a message on the display unit 12 that the product is not a discount target (step S04). On the other hand, when the product code is a product code to be discounted (step S03; Yes), the coupon issuing device 2 reads the member card (member number) possessed by the customer (step S05) and corresponds to the member number. In order to acquire customer information, a customer information acquisition request is transmitted to the store server 4 (step S06).

  The store server 4 receives the customer information acquisition request (step S07), and transmits customer information (customer weighting amount) corresponding to the member number to the coupon issuing device 2 (step S08). The coupon issuing device 2 receives customer information from the store server 4 (step S09). Then, the coupon issuing device 2 calculates the discount amount of the target product based on the product information and the customer information by the discount amount calculation procedure shown in FIG. 6 described later (step S10), and calculates the calculated discount amount. It displays on the display part 12 (step S11). When the coupon issue key 16 is pressed by the customer, the coupon issue device 2 issues a discount coupon C on which the discount amount is printed (step 12).

  Here, the procedure for calculating the discount amount of the target product will be described with reference to the flowchart showing the procedure for calculating the discount amount of the product in FIG. Here, it is assumed that the product code, the product category, and the customer weighting amount of the purchased customer have already been acquired.

  The discount amount calculation procedure includes the following four steps (S21 to S24). First, in step S21, a discount amount at the current time is calculated. Here, the remaining time from the current time to the closing time is calculated, and a discount amount (discount amount A) corresponding to the remaining time in the product category of the target product is calculated. Next, in step S22, a discount amount is calculated in consideration of the product weighting amount associated with the target product code. For example, if the product weighting amount is “1.1”, the discount amount B is calculated by multiplying the discount amount A calculated in step S21 by 1.1. Next, in step S23, a discount amount is calculated in consideration of the customer weighting amount. For example, if the customer weighting amount is “1.05”, the discount amount C is calculated by multiplying the discount amount B calculated in step S22 by 1.05. Finally, in step S24, a discount amount considering the maximum discount amount is calculated. That is, the discount amount is calculated so that the discount amount C calculated in step S23 does not exceed the maximum discount amount. For example, when “discount amount C> maximum discount amount”, the final discount amount is the maximum discount amount, and when “discount amount C ≦ maximum discount amount”, the final discount amount is the discount amount C.

  The discount amount of the target product is calculated by the procedure from step S21 to step S24. Note that the order of steps S22 and S23 is not limited to the above example, and may be reversed. In addition, whether or not to add each weighting amount in step S22 and step S23 to the discount amount is arbitrary, and both weighting amounts may be added, or any one weighting amount may be added. . Moreover, it is not necessary to consider both weighting amounts.

  As described above, according to the present embodiment, the discount amount (discount rate or discount amount) of the target product based on the product information read from the product and the remaining time from the current time to the store closing time. ) And a discount coupon C printed on it can be issued. As a result, if the remaining time is long (when there is still time until the closing time), the discount amount is lowered, and the discount amount is gradually increased (in steps) as the remaining time becomes shorter (as the closing time approaches). Thus, for the purpose of preventing unsold sales, it is possible to easily issue a discount coupon C on which a discount amount suitable for the situation (time) is printed. That is, it is possible to easily issue a discount coupon C in which the discount amount is flexibly changed as time passes.

  In calculating the discount amount of the product, the discount amount is calculated using the elapsed time from the cooking time or the manufacturing time of the product to the current time as a parameter. In the discount amount calculation procedure shown in FIG. It may be calculated. In this case, if the elapsed time is short, the discount amount is reduced, and as the elapsed time becomes longer, the discount amount is gradually increased to maintain the product in good condition. A discount coupon C on which a suitable discount amount is printed can be easily issued.

  In calculating the discount amount of the product, the discount amount is calculated using the remaining date and time from the current date and time until the expiration date or the expiration date of the product as a parameter. In the discount amount calculation procedure shown in FIG. It may be calculated. In this case, if the remaining date and time are long, the discount amount is lowered, and as the remaining date and time is shortened, the discount amount is gradually increased to reduce the amount of waste, and the discount amount suitable for the situation at that time is obtained. The printed discount coupon C can be issued easily.

  Further, as a discount amount calculation algorithm, a first calculation algorithm for calculating a discount amount using the remaining time from the current time to the closing time as a parameter, and an elapsed time from the cooking time or the manufacturing time included in the product information to the current time are used. The coupon issuing apparatus 2 includes a second calculation algorithm that calculates a discount amount as a parameter, and a third calculation algorithm that calculates a discount amount using a remaining date and time from the current date and time until the expiration date or expiration date included in the product information as a parameter. You may make it memorize | store and switch the calculation algorithm utilized according to a time slot | zone. Thus, for example, usually the discount amount is calculated based on the third calculation algorithm, and the discount amount is calculated based on the first calculation algorithm two hours before the closing of the store. Discount coupon C can be issued.

  Moreover, in this embodiment, although the customer weighting amount based on a customer's purchase history is calculated | required by the shop server 4, you may make it obtain | require not only by this but the coupon issuing apparatus 2. FIG. In this case, it can be realized by storing a table in which the purchase history and the customer weighting amount corresponding to the purchase history are associated with each other in the coupon issuing device 2 (flash ROM 34).

  In the present embodiment, the discount amount is calculated by the coupon issuing device 2. However, the present invention is not limited to this, and the discount amount may be calculated by the store server 4. In this case, it can be realized by providing the store server 4 with a function related to the discount amount calculation of the coupon issuing device 2 of the present embodiment and transmitting the product information read by the coupon issuing device 2 to the store server 4.

  Moreover, it is also possible to provide as a program for making a computer perform each step in the control method of the coupon issuing apparatus 2 shown in the above example. It is also possible to provide the program stored in a storage medium (not shown). As the recording medium, a CD-ROM, a flash ROM, a memory card (compact flash (registered trademark), smart media, memory stick, etc.), a compact disk, a magneto-optical disk, a digital versatile disk, a flexible disk, and the like can be used.

  In addition, the apparatus configuration of the coupon issuing device 2 and the processing steps of the method for calculating the discount amount of the product can be appropriately changed without departing from the gist of the present invention, regardless of the embodiment described above.
