(Embodiment 1)
Embodiment 1 of the present invention will be described. FIG. 1 is a network configuration diagram of a POS (Point Of Sales) system 1 according to one embodiment of the present invention. A POS system 1 shown in FIG. 1 includes a management server 10 and a plurality of POS terminals 20 . The management server 10 and the plurality of POS terminals 20 are communicably connected via a network 30 such as the Internet.

The POS system 1 can be installed, for example, in affiliated stores such as chain stores (restaurants, convenience stores, supermarkets, etc.). The management server 10 manages multiple POS terminals 20 . A plurality of POS terminals 20 are arranged at affiliated stores. For example, only one POS terminal 20 may be installed for each store.

FIG. 2 is a diagram showing a configuration example of the POS terminal 20. As shown in FIG. FIG. 3 is a diagram showing an example of the appearance of the POS terminal 20. As shown in FIG. 2 and 3, the same reference numerals are given to the same parts. A configuration example of the POS terminal 20 shown in FIG. 2 will be described below with reference to FIG.

The POS terminal 20 includes a CPU 201 , a ROM 202 , a RAM 203 , a hard disk 204 , a customer-side display section 205 , a biological information detection section 206 , a card payment section 207 , a cash storage section 208 , and a salesclerk-side display section 209 . , a key operation unit 210 , a scanner unit 211 , a printing unit 212 , an audio output unit 213 , and a communication unit 214 . They can communicate with each other via a bus.

The CPU 201 is a central processing unit, and controls the operation of the POS terminal 20 by reading and executing programs stored in the ROM 202 . The ROM 202 is a read-only memory, and stores various information used by the CPU 201 including programs.

A RAM 203 is a read/write memory and stores various information. For example, the RAM 203 stores information acquired from the outside (for example, a product master acquired from the management server 10), information generated during processing (for example, registration information (registration data) generated in registration processing for registering products, (settlement information, etc. generated in settlement processing for settlement (settlement) of products). In addition, the RAM 203 stores store clerk information including biometric information of the store clerk, attendance information on attendance of the store clerk, and the like.

The RAM 203 also stores additional information regarding product sizes and additional information regarding sales plans such as campaigns. Details of the additional information table that stores the additional information will be described later with reference to FIG. The RAM 203 also stores an addition history when the product quantity is added and a subtraction history when the product quantity is subtracted when product information is registered. The details of the addition history table that stores the addition history will be described later with reference to FIG. The details of the subtraction history table that stores the subtraction history will be described later with reference to FIG. The RAM 203 also stores a change history of product quantity determined based on the addition history and the subtraction history when product information is registered. Details of the change history table that stores the change history will be described later with reference to FIG.

The hard disk 204 stores various information. The hard disk 204 may store programs executed by the CPU 201 instead of the ROM 202, for example. Also, instead of the RAM 203, information obtained from the outside or information generated during processing may be stored.

The customer-side display unit 205 is a display for customers, and displays various information to customers. As shown in FIG. 3 , the display surface of the customer-side display section 205 faces the opposite direction to the display surface of the salesclerk-side display section 209 .

A biometric information detection unit 206 detects biometric information for authenticating a salesclerk. The biometric information is, for example, biometric information of finger veins, but is not limited to this, and may be information such as fingerprints, voiceprints, retinas, and irises. The biometric information of veins is, for example, a finger vein pattern obtained by analyzing the imaging result of a finger irradiated with near-infrared rays and imaged. Also, the biometric information detection unit 206 is, for example, externally attached to the POS terminal 20 and connected to the POS terminal 20 by wire or wirelessly.

However, the biometric information detection unit 206 is not limited to this, and may be incorporated in the POS terminal 20 . For example, the POS terminal 20 can use the biometric information detected by the biometric information detection unit 206 to generate attendance information and manage attendance. Also, the POS terminal 20 can use the biometric information detected by the biometric information detection unit 206 to log in the store clerk corresponding to the biometric information.

The card settlement unit 207 is a settlement mechanism using various cards (credit cards, prepaid cards such as transportation cards, etc.). The card payment unit 207 includes a card recognition unit (reading unit), a display unit, and an operation unit, and may include at least a card recognition unit. Note that the card recognition unit may recognize various types of cards (for example, membership cards, point cards, etc.) that are not directly used for payment (settlement).

The cash storage unit 208 is a storage unit that stores cash, and takes a drawn state and a stored state. The cash storage unit 208 is, for example, a drawer, and is pulled out when the store clerk operates a predetermined key of the key operation unit 210 . Also, the cash storage unit 208 is put into a stored state by being pushed in by the store clerk.

The clerk-side display unit 209 is a touch display for the clerk, which displays various information to the clerk and accepts various inputs from the clerk. For example, the clerk-side display unit 209 includes a button corresponding to the product for registering the product purchased by the customer, and a login button for logging in when recording attendance such as going to work or when registering the product. buttons are displayed.

The key operation unit 210 is composed of various keys (buttons) and receives various inputs from the store clerk. For example, the key operation unit 210 includes buttons for inputting numbers, cancel buttons for canceling (deleting) registered products, and subtotal buttons for calculating the total amount of registered products.

The scanner unit 211 optically reads, for example, a bar code (product code, etc.) attached to a product or a predetermined sheet, an employee code attached to a store clerk's name tag, or the like. The product is registered when the scanner unit 211 reads the bar code. Product registration is performed not only by scanning the barcode by the scanner unit 211, but also by operating a preset key corresponding to the product displayed on the clerk-side display unit 209, for example.

The printing unit 212 prints and issues purchase information such as the name of the store, the product purchased, and the date and time of purchase on various media (receipts, accounting tickets, etc.). The audio output unit 213 outputs audio. For example, the voice output unit 213 outputs a predetermined voice (for example, , and outputs a beep sound when a barcode is read. Also, the voice output unit 213 may output voice guidance. The communication unit 214 transmits and receives information to and from the management server 10 and other POS terminals 20 .

(Example of additional information table)
FIG. 4 is a diagram showing an example of the additional information table 40. As shown in FIG. The additional information table 40 is a table in which first additional information (for example, "size") and second additional information (for example, "sales plan") are associated with each product. PLU (price lookup) can be set in each field of the additional information table 40 . In the illustrated example, the additional information table 40 indicates that the product is blended coffee. In the additional information table 40, the horizontal axis (x-axis) indicates product sizes (S, M, L). The vertical axis (y-axis) indicates product sales plans (regular plans, 20-yen discount coupons, free flyers, etc.).

The size and sales plan are set for each product. For this reason, for example, if the product is pizza, there may be four or more sizes, and if the product is pasta, there may be two sizes, such as "normal" and "large serving." be. Some products do not have multiple sizes, and some products do not have applicable sales plans (additional information table 40 itself is not set). Moreover, the product is not limited to a single product, and may be a set menu.

The sales plan indicates the content of services set for each product. Specifically describing the sales plan, "regular plan" indicates a normal charge to which no discount is applied. "20 Yen Discount Coupon" indicates, for example, a charge that is a 20 Yen discount from the normal charge by applying the coupon. "Flyer free" indicates, for example, that a customer presents a leaflet to get free blended coffee (S size only). The "refill charge" indicates, for example, that if the same product is ordered again, the price will be reduced to half of the normal charge. "10% discount" indicates a charge that is 10% off the normal charge due to, for example, a campaign.

"50 yen discount" indicates a charge that is discounted by 50 yen from the normal charge by applying a coupon, for example. "100 yen discount" indicates a charge that is discounted by 100 yen from the normal charge by applying a coupon, for example. "Pasta coupon free" indicates, for example, that when the customer presents the pasta coupon, the blended coffee (S size only) is free when ordering pasta. "Company A Discount" indicates, for example, a discount rate when a coupon of affiliated company A is used. "Company B discount" indicates, for example, a discount charge when a coupon of an affiliated company B is used.

For example, in the additional information table 40, PLU101 (200 yen) is set in correspondence with the S size and the sales plan "normal". Also, the PLU 102 (180 yen) is set corresponding to the S size and the "20 yen discount coupon". Similarly, PLU is set in fields corresponding to other sizes and other sales plans. However, there are combinations in which no PLU is set. For example, in the case of M size and L size, PLUs corresponding to sales plans such as "free flyers" and "free pasta tickets" are not set. In other words, in the case of blended coffee, the sales plan may not be applied depending on the size.

Also, when the product is blended coffee, in addition to the three sizes described above, there may be other sizes such as "LL". As for the other sizes, PLU may be set in each field corresponding to the sales plan in the same manner as the three types described above. If, for example, none of the sales plans are applicable to the other size, PLU should be set to none of the fields corresponding to the other size and the sales plan.

(An example of the screen when registering products)
FIG. 5 is a diagram showing an example of a screen when registering products. In FIG. 5, the clerk-side display unit 209 includes an operation input display area 500 for a plurality of preset keys, etc., and a registration display area 510 for displaying product information of registered products, payment amounts, and the like. When a button corresponding to a product to be registered is pressed among the preset keys displayed in the operation input display area 500 , the pressed product and its price are displayed in the registration display area 510 .

The registration display area 510 includes product display areas 511 ( 511 a and 511 b ) and a non-product display area 512 . The product display area 511 is an area in which registered product information is displayed for each product. "1" of "1 blend 200" shown in the product display area 511a indicates the quantity "1", "blend" indicates the product name "blend coffee", and "200" indicates the amount "200 yen". , that is, one blended coffee of 200 yen is registered. Also, the product display area 511b indicates that one latte of 270 yen is registered. In the case of a set product (set menu), the quantity is registered for each set product. Also, if a single product has options, the options are also registered and displayed in the product display area 511 .

The non-product display area 512 is an area different from the product display area 511 in the registration display area 510, and includes a blank area and an amount area. Information other than product information is displayed in the margin area and the amount area. For example, in the blank area, products to be registered later can be displayed, and nothing is displayed in the drawing. However, in the blank area, for example, when the store clerk operates an addition area 601 (see FIG. 6) to be described later in the product display area 511, a notification screen for notifying the addition may be displayed, A selection screen or the like for accepting whether or not to allow the addition may be displayed. In addition, the amount area displays information indicating the number of customers, the number of items registered, the total amount, and the like.

(Example of operation procedure and screen transition when changing product quantity)
FIG. 6 is a diagram showing an example of an operation procedure and screen transitions when changing the quantity of a product. In FIG. 6, the product display area 511b (511a) includes an addition area 601 that receives an operation for adding the product quantity and a subtraction area 602 that receives an operation for subtracting the product quantity. Although the case of changing the quantity of products shown in the product display area 511b will be described below, the same applies to the case of changing the quantity of products shown in the product display area 511a.

First, each display area will be described. In FIG. 6, an addition area 601 is an area in which, for example, the quantity of products is displayed. A subtraction area 602 is, for example, an area where a product name is displayed. An addition area 601 and a subtraction area 602 are areas surrounded by dotted lines. Although the dotted lines are not actually displayed, they may be displayed from the viewpoint of making it easier for the store clerk to grasp each area. Also, the addition area 601 and the subtraction area 602 may be displayed differently from the other areas. good too.

Next, the operation procedure will be explained. As shown in (A1) of FIG. 6, it is assumed that store clerk 610 presses (touches) addition area 601 corresponding to product "1" to be registered. In this case, the cursor 630 points to the product display area 511b indicating "latte", that is, "latte" is specified. Simultaneously with this designation, the quantity of "latte" is added as shown in (A2), for example, the quantity of "latte" becomes "2".

On the other hand, as shown in (B1) of FIG. 6, it is assumed that store clerk 610 presses subtraction area 602 corresponding to the product "latte" to be registered. In this case, similarly to (A1), the cursor 630 points to the product display area 511b indicating "latte", that is, "latte" is designated. Simultaneously with this designation, the quantity of "latte" is subtracted as shown in (B2), for example, the quantity of "latte" becomes "0". Even after the quantity becomes "0", the product display area 511b indicating the product "latte" continues to be displayed.

Further, after the quantity becomes "0", the display mode of the product display area 511b is displayed in a special display mode different from the display mode of the product display area 511a indicating the other product "blend". Specifically, the display mode of "0 latte 0" in the product display area 511b indicating the product "latte" is displayed in a special display mode different from the normal display mode, which is the display mode of "1 blend 200". In the drawing, the special display mode is, for example, a bold display mode. However, the special display mode is not limited to bold type, and may be a display color different from other characters (blend), a size different from other characters, or a background of other characters. A background color or the like different from the color may be used.

Also, it may be possible to switch whether to display the product display area 511 after the quantity becomes “0”. For example, it may be possible to set in advance whether or not to display the product display area 511 even after the quantity becomes “0”. In addition, when the quantity becomes "0", a screen for selecting whether or not to display the product in the product display area 511 is displayed each time. It may be displayed in the display area 511 .

In addition, in FIG. 6, an addition area 601 is used to display the product quantity, and a subtraction area 602 is used to display the product name. This makes it easy for the store clerk to associate the quantity with the increase in quantity, and the sales clerk can easily understand that pressing the addition area 601 increases the quantity. Therefore, for example, even a salesclerk unfamiliar with the POS terminal 20, such as a newcomer, can prevent operation errors and facilitate the registration operation related to quantity correction.

Also, the addition area 601 and the subtraction area 602 may be reversed. That is, the area where the product quantity is displayed is used as an area for accepting an operation for subtracting the product quantity, while the area where the product name is displayed is an area for accepting an operation for increasing the product quantity. may be As a result, the area for receiving addition can be made wider than the area for receiving subtraction.

For example, when the frequency of addition operations is expected to be higher than the frequency of subtraction operations, the larger display area is used as an area for receiving additions, thereby causing the amount to be added. The operation (touch) at the time can be facilitated, and operation errors can be suppressed. It should be noted that by storing histories indicating the number of times addition and subtraction have been performed, the one with the higher operation frequency may be set in the larger area of the display area. That is, the POS terminal 20 may set an area for decreasing the quantity and an area for increasing the quantity based on the history of operation frequency. Further, when performing the setting, confirmation of whether or not to perform the setting may be received from the store clerk.

Further, the contents displayed in the registration display area 510 are printed on the receipt when the settlement process is completed. In this case, items whose quantity is "0" are not printed on receipts because they are irrelevant to the settlement. However, the receipt may be printed even for the product whose quantity is "0". In this way, by having the receipt printed even for the product whose quantity is "0", the customer can grasp the progress at the time of ordering (change in order content).

Further, in the first embodiment, the POS terminal 20 may permit correction when biometric authentication using biometric information is successful. Specifically, the POS terminal 20 has a biometric information detector 206 (see FIG. 2). The POS terminal 20 may perform authentication using the biometric information detected by the biometric information detection unit 206 when correcting the registered product (including correcting the quantity to "0"). More specifically, when canceling a registered product, the POS terminal 20 notifies the store clerk to enter authentication information, performs biometric authentication using the authentication information received from the store clerk, and performs biometric authentication. Correction may be allowed if successful.

Here, in a restaurant, a clerk's dishonesty (for example, embezzlement of cash) is performed by canceling a registered product or performing a return or refund operation before or after pressing a subtotal button. Sometimes.

Here, for example, fraud in the case of canceling a registered product before pressing the subtotal button will be described. First, the premised configuration will be described. The POS terminal 20 accepts an instruction (for example, operation of a "subtotal button") by a store clerk to the effect that a product to be purchased by a customer is registered and the registration of the product is completed. With this, it becomes possible to print out the receipt after the registration of the product is completed. As a result, the information of the product for which registration has been completed is stored as sales data. On the other hand, if the instruction to complete the product registration is not accepted, that is, if the operation of the "subtotal button" is not accepted, the product information being registered is not stored as sales data.

Generally, in a restaurant, it is possible to manage the sales separately from the sales quantity and the order quantity for products that can be managed in inventory and foods that need to be ordered from the kitchen, so that fraud by the staff is less likely to occur. On the other hand, in the case of drinks, etc., where it is difficult to manage inventory by quantity, it is possible for the clerk to provide the drink to the customer without completing the registration of the product (drink). Specifically, when there is an order for a drink, the clerk registers the product once, but before completing the registration of the product (before operating the "subtotal button"), for example, the customer does not need a receipt. Suppose there is an offer.

In this case, by canceling the product being registered, the store clerk offers a drink to the customer without completing the product registration (without storing it in the sales data), and commits fraud such as embezzling the money received from the customer. may act. Fraudulent acts include not only embezzlement of cash, but also free provision of goods. Specifically, if a store clerk notices that a customer is an acquaintance after registering an item, the store clerk may cancel the registered item and provide the item for free. In order to help identify such a fraudulent salesclerk, when correcting the number of products to "0", the POS terminal 20 prompts the salesclerk to input biometric information, and uses the biometric information that has been input. Perform biometric authentication.

Then, the POS terminal 20 corrects the product quantity to "0" when the biometric authentication using the input biometric information is successful. As a result, the POS terminal 20 can identify the clerk who made the correction using the input biometric information. In addition, the POS terminal 20 accumulates a history (clerk's information and corrected product information) related to corrections of each specified salesclerk. Thus, by using the history, the POS terminal 20 can identify a store clerk with a high frequency of correction as a store clerk with a high possibility of committing fraud. In addition, users such as store managers and owners, for example, can analyze the situation and trends when correction operations are performed, which can be useful in monitoring store staff who may be committing fraud. can.

In the above explanation, an example of fraud due to correction being made before pressing the subtotal button was explained, but even after pressing the subtotal button, pressing the subtotal button can be canceled and Fraud (eg, embezzlement of cash) may occur. Also, in the case of corrections related to replacement or return of defective products, there are cases where similar unauthorized corrections are made by store clerks. For this reason, the POS terminal 20 prompts the clerk to input biometric information, and performs biometric authentication using the input biometric information, even when making corrections after pressing the subtotal button or when making corrections related to the exchange or return of defective products. It may be done.

Then, if the biometric authentication using the input biometric information is successful, the POS terminal 20 permits correction after pressing the subtotal button and correction related to exchange or return of defective products. can identify the clerk who made the correction using the input biometric information, and can identify the clerk who is highly likely to have committed the fraud by accumulating the correction history. can be done.

In the first embodiment, the case where the POS terminal 20 performs biometric authentication has been described, but the present invention is not limited to this, and another device (eg, management server 10) may perform biometric authentication. Specifically, the biometric information received by the POS terminal 20 is transmitted to the management server 10 when the product is corrected. The management server 10 performs match determination (biometric authentication) using the biometric information of each clerk stored in its own device or another device and the biometric information transmitted from the POS terminal 20, and the authentication result of the biometric authentication to the POS terminal 20 . Even with such a configuration, the POS terminal 20 can use the authentication result of biometric authentication to permit correction of the registered product.

Further, the storage unit for accumulating the history of corrections made by each identified salesclerk may be provided in the POS terminal 20, or may be provided in another device (for example, the management server 10). Also, another device (management server 10) may use the history to identify a store clerk with a high frequency of correction as a store clerk with a high possibility of committing fraud.

Further, in the above description, an operation related to canceling a registered product has been described as an example of correcting a product that requires biometric authentication, but the operation is not limited to cancellation and may be other correcting operations. Specifically, for example, when changing (including adding to) registered product information after a subtotal button is pressed, biometric authentication may be performed by receiving biometric information from a store clerk. As a result, it is possible to identify a store clerk who frequently performs corrective operations (for example, erroneous operations and incorrect inputs), which can be useful for educating and instructing the store clerk.

(Example of product registration processing performed by POS terminal 20)
FIG. 7 is a flowchart showing an example of product registration processing performed by the POS terminal 20. As shown in FIG.

Step S11: The POS terminal 20 determines whether or not there is a touch on the clerk-side display section 209, an operation on the key operation section 210, a scan by the scanner section 211, or the like. The POS terminal 20 waits when there is no scanning or the like, and proceeds to step S12 when there is scanning or the like.
Step S12: The POS terminal 20 registers the product and displays it on the clerk-side display unit 209, and proceeds to step S13.

Step S13: The POS terminal 20 determines whether or not the addition area 601 has been pressed. If the addition area 601 is not pressed, the POS terminal 20 proceeds to step S15. When the addition area is pressed, the POS terminal 20 proceeds to step S14.
Step S14: The POS terminal 20 performs quantity addition processing (see FIG. 8), and proceeds to step S15.

Step S15: The POS terminal 20 determines whether or not the subtraction area 602 has been pressed. If the subtraction area 602 is not pressed, the POS terminal 20 proceeds to step S17. When the subtraction area 602 is pressed, the POS terminal 20 proceeds to step S16.
Step S16: The POS terminal 20 performs quantity subtraction processing (see FIG. 9), and proceeds to step S17.

Step S17: The POS terminal 20 determines whether or not the subtotal button of the key operation unit 210 has been pressed. If the subtotal button is not pressed, the process returns to step S11. When the subtotal button is pressed, the POS terminal 20 proceeds to step S18.
Step S18: The POS terminal 20 displays a small plan screen, and proceeds to step S19.
Step S19: The POS terminal 20 determines whether or not it has received a settlement operation such as inputting a deposit or pressing a cash total button. The POS terminal 20 waits until the settlement operation is accepted, and when the settlement operation is accepted, the process proceeds to step S20.

Step S20: The POS terminal 20 performs settlement processing such as issuing a receipt, and ends the series of processing. Note that, in the settlement process, change corresponding to the deposit or the cash balance in the settlement process may be released. Also, transaction history information (sales data) is stored in the settlement process.

Step S33: The POS terminal 20 determines whether or not the return is from the quantity "0". If the POS terminal 20 does not return from the quantity "0", it proceeds to step S15 in FIG. If the POS terminal 20 returns from the quantity "0", the process proceeds to step S34.
Step S34: The POS terminal 20 changes (returns) the display mode of the product to be added to the normal display mode, and proceeds to step S15 in FIG.

(Example of quantity subtraction processing performed by the POS terminal 20 according to the first embodiment)
FIG. 9 is a flowchart showing an example of quantity subtraction processing performed by the POS terminal 20. As shown in FIG.

Step S41: The POS terminal 20 designates the product to be subtracted, and proceeds to step S42.
Step S42: The POS terminal 20 subtracts the quantity and proceeds to step S43.
Step S43: The POS terminal 20 determines whether or not the quantity is "0". If the quantity is not "0", the POS terminal 20 proceeds to step S17 in FIG. If the quantity is "0", the POS terminal 20 proceeds to step S44.
Step S44: The POS terminal 20 changes the display mode of the product to be subtracted to a special display mode, and proceeds to step S17 in FIG.

As described above, in the POS terminal 20 according to the first embodiment, the quantity of products can be changed without the store clerk performing an operation to specify the products. Therefore, it is possible to reduce the number of operations when the store clerk changes the quantity of products. In addition, since the area indicating the product name and the area indicating the quantity of the displayed product information are touched, the product to be changed is easy for the store clerk to understand, and operation errors can be suppressed. Therefore, it is possible to reduce the burden on the store clerk involved in correcting the quantity. Also, the time required for product registration can be shortened, and the customer service time can be shortened.

Further, in the POS terminal 20 according to the first embodiment, only the product and the quantity of the product are displayed, in other words, only the minimum necessary information is displayed in the product display area 511 (see FIG. 5). quantity can be added or subtracted. Therefore, it is possible to reduce the proportion of the product display area 511 in the display area (registered display area 510). As a result, information other than the product and the quantity of the product can be displayed in the registration display area 510, and the display area can be effectively utilized.

(Modification of Embodiment 1)
Next, a modification of Embodiment 1 of the present invention will be described. In addition, in this modification, the display modes of the addition area and the subtraction area included in the product display area are different from those in the above-described first embodiment. In the following description, the same reference numerals are given to the same contents as those described in the first embodiment, and the description thereof is omitted.

(Modified example of the screen when registering products and the operation procedure when changing the quantity of products)
FIG. 10 is a diagram showing a modification of the screen for registering products and the operation procedure for changing the quantity of products. In FIG. 10, the registration display area 510 includes product display areas 511 (511f, 511g) and a non-product display area 512. As shown in FIG. The product display area 511 includes an addition area 701 that receives an operation for increasing the quantity of goods, and a subtraction area 702 that receives an operation for subtracting the quantity of goods.

The addition area 701 is, for example, an area showing an upward arrow "↑". The subtraction area 702 is, for example, an area showing a downward arrow "↓". The marks displayed in the addition area 701 and the subtraction area 702 are not limited to "↑" and "↓". or a number such as "+1" or "-1".

Suppose that store clerk 610 presses (touches) addition area 701 as shown in (A1) of FIG. In this case, the cursor 630 points to the product display area 511g indicating "latte", that is, "latte" is designated. Simultaneously with this designation, the quantity of "latte" is added as shown in (A2), for example, the quantity of "latte" becomes "2".

On the other hand, as shown in (B1) of FIG. 10, it is assumed that store clerk 610 presses subtraction area 602 . In this case, similarly to (A1), the cursor 630 points to the product display area 511g indicating "latte", that is, "latte" is designated. Simultaneously with this designation, the quantity of "latte" is subtracted as shown in (B2), for example, the quantity of "latte" becomes "0". Even after the quantity becomes "0", the product display area 511f indicating the product "latte" continues to be displayed. After the quantity becomes "0", the display mode of the product display area 511g showing the product "latte" is displayed in a special display mode different from the product display area 511f of the other registered product "blend". be done.

Even in such a modified example, as in the first embodiment described above, it is possible to change the quantity of products without the store clerk performing an operation to specify the products. In addition, in the case of this modified example, both the addition area 701 and the subtraction area 702 are displayed by arrows, so that the store clerk can determine whether the quantity is added or subtracted by pressing which one. can be easily grasped. For this reason, even a store clerk unfamiliar with the POS terminal 20, such as a newcomer, can suppress operational errors related to the addition and subtraction of the quantity, and the burden on the store clerk related to the correction of the quantity can be reduced.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described. It should be noted that the second embodiment differs from the above-described first embodiment in that additional information such as size and sales plan is also displayed in the display of product information. In the description of the second embodiment, the same reference numerals are given to the contents similar to those described in the first embodiment, and the description thereof is omitted.

(Example of operation and screen when changing additional information for specific products)
First, with reference to FIG. 11, an example of operations and screens for changing additional information of a specific product will be described. FIG. 11 is a diagram showing an example of an operation and a screen when changing additional information of a specific product. The additional information is the size and sales plan. Also, the specific product is a product having multiple pieces of additional information (multiple sizes and multiple sales plans). In FIG. 11, for example, a case of changing a sales plan for a product with the same product name (blended coffee) will be described.

First, each display area will be described. In FIG. 11, the registration display area 510 includes product display areas 511 (511f, 511g, 511h) and a non-product display area 512. As shown in FIG. In (A) of FIG. 11, the product display area 511f has one L-size blended coffee of 180 yen to which the 20-yen discount coupon sales plan is applied (hereinafter, appropriately referred to as "20-yen discount L blend"). Indicates that it is registered. Specifically, "L" of "1 blend L 20 yen discount 180" shown in the product display area 511f indicates the size, and "20 yen discount" indicates the sales plan.

In addition, the product display area 511g indicates that one 150-yen M size blended coffee to which the normal plan is applied (hereinafter referred to as "normally planned M blend") is registered. Specifically, the "-" of "1 Blend M-180" shown in the product display area 511g indicates that the normal sales plan is applied. In addition, the product display area 511h indicates that one L-size blended coffee of 200 yen to which the normal plan is applied (hereinafter referred to as "normally planned L blend") is registered.

An addition area 601 in the product display area 511f is a button for adding the quantity of the L blend of 20 yen off. A subtraction area 602 in the product display area 511f is a button for subtracting the quantity of the L blend of 20 yen off. Note that the other product display areas 511g and 511h similarly include an addition area 601 and a subtraction area 602 for changing the quantity of each product.

Here, when accepting an order for a product, a customer may request a change in size or a change in sales plan. For example, when a plurality of customers in the same group place orders at the same time, other customers often reorder (correct) an order placed by one customer. Specifically, for example, one customer ordered the L blend of the regular plan, but a colleague ordered the L blend with a 20 yen discount, so the customer ordered the L blend with a 20 yen discount. There are times when I would like to propose a change. The operating procedure of the store clerk in such a case will be described below.

In this case, the store clerk 610 presses (touches) an addition area 601 included in the product display area 511f, for example, as shown in FIG. 11A. By this operation, the cursor 630 points to the product display area 511f indicating the L blend of 20 yen discount, that is, the L blend of 20 yen discount is designated. Simultaneously with this designation, as shown in the product display area 511f of (B), the quantity of L blend with a discount of 20 yen is added, and the quantity becomes "2". When the quantity is added, the POS terminal 20 stores the history (addition history) for a predetermined period (for example, the period until the subtotal button is pressed).

Furthermore, as shown in (B), salesclerk 610 presses (touches) subtraction area 602 included in product display area 511h. By this operation, the cursor 630 points to the product display area 511h indicating the L blend of the normal plan, that is, the L blend of the normal plan is specified. Simultaneously with this designation, as shown in the product display area 511h of (C), the quantity of the L blend of the normal plan is subtracted, and the quantity becomes "0". When the quantity is subtracted, the POS terminal 20 stores the history (subtraction history) for a predetermined period (for example, the period until the subtotal button is pressed). Even after the quantity becomes "0", the product display area 511h indicating the L blend of the normal plan is continuously displayed. In this way, it is possible to change the sales plan for the L-size blended coffee from the normal sales plan to the 20-yen discount coupon sales plan.

Here, when there is a change in additional information (change in sales plan) for a product with the same product name (blend coffee), the POS terminal 20 indicates that the sales plan has been changed for a predetermined period of time. Store change history. In determining whether or not the sales plan has been changed, the POS terminal 20 compares the addition history and the subtraction history, and if the product name and size are the same and only the sales plan is different, the sales plan is changed. determine that there was Each history (addition history, subtraction history, change history) will be described later with reference to FIGS. 13 to 15. FIG. The predetermined period for storing each history is not limited to, for example, the period until the subtotal key is pressed, but may be the period until the settlement process is completed, a preset fixed period, or another product. It may be until the registration of is started. Also, each history may be stored in the management server 10 .

In the description of FIG. 11, the order of operations for changing the sales plan is to first perform the operation of adding the L blend of 20 yen discount, and then perform the operation of subtracting the L blend of the normal plan. However, the order may be reversed. That is, the operation of subtracting the L blend of the normal plan shown in (B) may be performed first, and then the operation of adding the L blend of 20 yen discount shown in (A) may be performed. Even if this is done, as shown in (C), the quantity of the L blend of 20 yen discount can be set to "2" and the quantity of the L blend of the normal plan can be set to "0".

In addition, in the explanation of FIG. 11, as an example of changing the additional information, the case of changing the sales plan was explained, but the same applies to the case of changing the size. For example, when changing the size between the normal plan M blend shown in the product display area 511g and the normal plan L blend shown in the product display area 511h, the POS terminal 20 adds one and subtracts the other. Then, the addition history and the subtraction history are compared, and if the product name and sales plan are the same and only the size is different, it can be determined that the size has been changed.

Here, when receiving an order for a product from a customer, additional information such as size change or sales plan may be changed, but the customer may withdraw the change. For example, a customer may request to change the sales plan, but the coupon (sales plan) cannot be applied because the customer does not have the coupon corresponding to the sales plan or the coupon has expired. . In the example shown in FIG. 11, the original sales plan (regular plan) may be restored even though the normal plan L blend is changed to the 20-yen discount L blend. The operation of the store clerk in such a case will be described below with reference to FIG. 12 .

FIG. 12 is a diagram showing an operation screen for restoring the original sales plan for a product whose sales plan has been changed. As shown in FIG. 12A, the store clerk 610 presses (touches) the addition area 601 of the product display area 511h indicating the L blend of the normal plan, for example. As a result, the cursor 630 points to the product display area 511h indicating the L blend of the normal plan, that is, the L blend of the normal plan is designated. Simultaneously with this designation, the quantity of the L blend of the normal plan is added as shown in (C), and the quantity becomes "1". Also, by referring to the change history, the POS terminal 20 subtracts the amount of the L blend of 20 yen discount at the same time as this addition, and returns the amount to "1".

As shown in (A) of FIG. 12, since the display of products whose quantity has become "0" is continued, the store clerk can easily grasp the deleted products. In addition, when re-registering the product, the quantity of the product can be set to "0" with a simple operation without the clerk pressing the button for selecting the product or pressing the button for specifying the size. can be returned to "1".

Further, the operation to return to the original product (normally planned L blend) is not limited to the operation shown in (A) of FIG. 12, and may be the operation shown in (B). That is, as shown in (B), the store clerk 610 presses (touches) the subtraction area 602 included in the product display area 511c indicating the L blend with a discount of 20 yen. As a result, the cursor 630 points to the product display area 511f indicating the 20-yen discount L blend, that is, the 20-yen discount L blend is designated. Simultaneously with this designation, as shown in (C), the quantity of the L blend with a discount of 20 yen is subtracted, and the quantity becomes "1". Also, by referring to the change history, the POS terminal 20 adds the quantity of the L blend of the normal plan at the same time as this subtraction, and returns the quantity to "1".

As shown in FIG. 12, the POS terminal 20 performs an operation of adding (or subtracting) one of the two products whose sales plan has been changed to the original sales plan. When accepted, not only is the addition (or the subtraction) performed, but the other is automatically subtracted (or added). As a result, it is possible to simplify the operation for restoring the original size after a sales plan or size change.

Also, for example, it may be possible to set in advance whether or not to automatically change the quantity. Also, for example, although the quantity is automatically changed, there are cases where the automatic change does not have to be performed. For this reason, when automatic change is performed, the clerk may be notified to that effect each time. Alternatively, a screen for selecting whether or not to confirm the automatic change may be displayed, and the automatic change may be confirmed when a request to confirm the automatic change is received.

(Example of addition history table stored in POS terminal 20)
Next, an example of the addition history table stored by the POS terminal 20 will be described. FIG. 13 is an explanatory diagram showing an example of an addition history table stored by the POS terminal 20. As shown in FIG. In FIG. 13, the addition history table 810 includes customer information and addition numbers. , and product information fields. By storing information in each field, addition history information 811 (811a, 811b, 811c) is stored as a record.

Customer information is identification information such as a membership card that identifies a customer, and includes customer attribute information such as gender and age. The customer information is input, for example, by reading the membership card presented by the customer at the stage prior to accepting the order by the card reading unit (for example, the card settlement unit 207). If the customer does not have a membership card, the store clerk may directly input customer attribute information such as gender and age.

Addition No. is identification information for identifying the addition history information 811 . The product information includes information indicating the product name and additional information. The product name is the product name such as “blended coffee” or “latte”. The additional information includes information indicating the size and information indicating the sales plan. One or a plurality of sizes are prepared according to the product. For example, in the case of "blend coffee", as shown in the additional information table 40 of FIG. 4, three sizes of "S", "M" and "L" are prepared. The sales plan is the contents of the service set for each product, such as a regular plan, a 20-yen discount coupon, and free flyers.

(Example of subtraction history table stored in POS terminal 20)
Next, an example of the subtraction history table stored by the POS terminal 20 will be described. FIG. 14 is an explanatory diagram showing an example of a subtraction history table stored by the POS terminal 20. As shown in FIG. It should be noted that in the following description, the description of the same contents as those described in the addition history table 810 shown in FIG. 13 will be omitted.

In FIG. 14, the subtraction history table 820 includes customer information and addition number. , and product information fields. By storing information in each field, subtraction history information 821 (821a, 821b, 821c) is stored as a record. Subtract No. is identification information for identifying the subtraction history information 821 .

(Example of change history table stored by POS terminal 20)
Next, an example of the change history table stored by the POS terminal 20 will be described. FIG. 15 is an explanatory diagram showing an example of the change history table stored by the POS terminal 20. As shown in FIG. In FIG. 15, the sales plan change history table will be described, and the size change change history table will be omitted. In FIG. 15, the change history table 830 includes plan change numbers. and addition No. and subtraction No. , and product information fields. By storing information in each field, change history information 831 (831a) is stored as a record.

Plan change no. is identification information for identifying the change history information 831 . Addition No. is information included in the addition history information 811 (see FIG. 13). Subtract No. is information included in the subtraction history information 821 (FIG. 14). The product information indicates the product name and additional information (size). Specifically, the change history information 831a includes addition numbers. The addition history information 811a of "c01" and the subtraction No. It indicates that the product information is common to the subtraction history information 821a of "d02". In other words, the change history information 831 indicates that there was a mutual change in the sales plan for the product (L blend) indicated by the product name “blend” with the size “L”.

By using such a change history table 830, the POS terminal 20, after changing the sales plan of the product ordered by the customer, can return the change (change again), and the quantity of the product for which the change has been accepted. , it is possible to anticipate the corresponding product and change the quantity.

To give a specific example, the POS terminal 20 first subtracts product A (for example, L blend of normal plan) and adds product B (for example, L blend of 20 yen discount). Then, by associating the product A and the product B, when the addition of the product A is accepted after that, the product B can be subtracted (automatic subtraction) along with the addition of the product A. Also, if the POS terminal 20 makes a change to add product A and subtract product B first, then by associating product A and product B, subtraction of product A is received after that. In addition, it is possible to add (automatically add) product B together with subtraction of product A.

Although illustration is omitted, the addition history table 810, the subtraction history table 820, and the change history table 830 may each include information indicating date and time, information indicating weather such as temperature, and the like. Also, the information stored in each table may be accumulated without being erased after a predetermined period of time (for example, after pressing a subtotal key). As a result, addition histories and subtraction histories can be obtained according to conditions such as customers, seasons, time zones, and weather. By analyzing these histories, for example, it is possible to predict the products to be registered according to the conditions. The change can be predicted. As a result, for example, when addition is predicted when the L blend of the normal plan is registered, the addition area is displayed large, the predicted quantity and product are displayed in a pop-up, and the predicted content is displayed to the clerk. may notify you.

Further, for example, when there is a history of canceling the automatic change by the clerk depending on the product even though the quantity is automatically changed, the quantity of the product can be set so as not to be automatically changed. That is, it is also possible to set whether or not to automatically change the quantity afterward according to the history of the cancellation operation performed by the store clerk after the automatic change. Further, in setting whether or not to automatically change the quantity, various conditions such as the customer, the season, the time zone, and the weather may be taken into consideration. That is, for example, it is possible to set automatic change for a certain customer and set automatic change not to be made for another customer according to customer attribute information.

(Example of product registration processing performed by the POS terminal 20 according to the second embodiment)
FIG. 16 is a flowchart showing an example of product registration processing performed by the POS terminal 20 according to the second embodiment. In addition, in the description of FIG. 16, points different from the description of FIG. 7 will be described.
Step S50: The POS terminal 20 erases each piece of history information (addition history information, subtraction history information, change history information) after displaying the small plan screen in step S18, and proceeds to step S19. Note that the POS terminal 20 may transmit each piece of history information to the management server 10 . The management server 10 may accumulate each piece of history information, for example. Thereby, in the management server 10, each piece of history information can be aggregated and used for analysis of each piece of history information.

FIG. 17 is a flowchart showing an example of quantity addition processing performed by the POS terminal 20 according to the second embodiment.
Step S51: The POS terminal 20 designates the product to be added, and proceeds to step S52.
Step S52: The POS terminal 20 adds the quantity and proceeds to step S53.
Step S53: The POS terminal 20 determines whether or not the product to be added includes additional information (specific product). If the product to be added does not include additional information, the POS terminal 20 proceeds to step S15 in FIG. If the product to be added includes additional information, the POS terminal 20 proceeds to step S54.

Step S54: The POS terminal 20 determines whether or not the return is from the quantity "0". If the POS terminal 20 does not return from the quantity "0", specifically, for example, as shown in FIGS. The process proceeds to step S55. When the POS terminal 20 returns from the quantity "0", specifically, for example, as shown in (A) and (C) of FIG. Proceed to S59.

Step S55: The POS terminal 20 stores the addition history information of the product to be added in the addition history table 810 (see FIG. 13), and proceeds to step S56.
Step S56: The POS terminal 20 refers to the subtraction history table 820 (see FIG. 14) and determines whether subtraction history information is stored. If the POS terminal 20 does not store the subtraction history information, it proceeds to step S15 in FIG. On the other hand, if the subtraction history information is stored in the POS terminal 20, the process proceeds to step S57.

Step S57: The POS terminal 20 compares the product information to be added and the subtraction history information, and stores the subtraction history information having common product information (product name and size) other than the sales plan in the subtraction history table 820. Determine whether or not If the subtraction history table 820 stores subtraction history information that has common product information (product name and size) other than the sales plan, that is, if the change in the sales plan is recognized, the POS terminal 20 performs step Proceed to S58. On the other hand, if the subtraction history table 820 does not store subtraction history information having common product information (product name and size) other than the sales plan, the POS terminal 20 proceeds to step S15 in FIG.

Step S58: The POS terminal 20 stores the change history information in the change history table 830 (see FIG. 15), and proceeds to step S15 in FIG.

Step S60: The POS terminal 20 refers to the change history table 830 and determines whether change history information is stored. If no change history information is stored in the change history table 830, the POS terminal 20 proceeds to step S15 in FIG. On the other hand, if change history information is stored in the change history table 830, the POS terminal 20 proceeds to step S61.

Step S61: The POS terminal 20 compares the product information to be added and the change history information, and stores the change history information having common product information (product name and size) other than the sales plan in the change history table 830. Determine whether or not If the change history table 830 does not store change history information having common product information (product name and size) other than the sales plan, the POS terminal 20 proceeds to step S15 in FIG. If the change history table 830 stores change history information having common product information (product name and size) other than the sales plan, the POS terminal 20 proceeds to step S62.

Step S62: The POS terminal 20 subtracts (automatically subtracts) the product quantity corresponding to the product to be added, and proceeds to step S15 in FIG. The product corresponding to the product to be added (normally planned L blend) is the product that is automatically subtracted. It is a product corresponding to (20 yen discount L blend).

After the process of step S62, it may be displayed that the quantity of the product corresponding to the product to be added has been subtracted. Along with the display, whether or not to cancel the automatic subtraction of the quantity may be accepted, and when the cancellation is accepted, the automatic subtraction may be canceled. Further, by storing and accumulating the result of whether or not the automatic subtraction has been canceled for each product, it is possible to automatically subtract the quantity according to the history of the cancellation operation performed by the store clerk.

(Example of quantity subtraction processing performed by the POS terminal 20 according to the second embodiment)
FIG. 18 is a flowchart showing an example of quantity subtraction processing performed by the POS terminal 20 according to the second embodiment.

Step S71: The POS terminal 20 designates the product to be subtracted, and proceeds to step S72.
Step S72: The POS terminal 20 subtracts the quantity and proceeds to step S73.
Step S73: The POS terminal 20 determines whether or not the quantity is "0". If the quantity is not "0", specifically, for example, as shown in (B) and (C) of FIG. Proceed to S81. When the quantity is "0", the POS terminal 20 subtracts the L blend of the normal plan to "0", as shown in FIGS. 11B and 11C, for example. If so, the process proceeds to step S74.

Step S74: The POS terminal 20 changes the display mode of the product to be subtracted to a special display mode, and proceeds to step S75.
Step S75: The POS terminal 20 determines whether or not the product to be subtracted includes additional information (specific product). If the product to be subtracted does not include additional information, the POS terminal 20 proceeds to step S17 in FIG. If the product to be subtracted includes additional information, the POS terminal 20 proceeds to step S76.

Step S76: The POS terminal 20 stores the subtraction history information of the product to be subtracted in the subtraction history table 820 (see FIG. 14), and proceeds to step S77.
Step S77: The POS terminal 20 refers to the addition history table 810 (see FIG. 13) and determines whether addition history information is stored. When the addition history information is not stored in the POS terminal 20, the process proceeds to step S17 in FIG. On the other hand, if the addition history information is stored in the POS terminal 20, the process proceeds to step S78.

Step S78: The POS terminal 20 compares the product information to be subtracted with the addition history information, and stores the addition history information having common product information (product name and size) other than the sales plan in the addition history table 810. Determine whether or not If the addition history table 810 stores addition history information that has common product information (product name and size) other than the sales plan, that is, if the change in the sales plan is recognized, the POS terminal 20 performs step Proceed to S78. On the other hand, if the addition history table 810 does not store addition history information having common product information (product name and size) other than the sales plan, the POS terminal 20 proceeds to step S17 in FIG.

Step S79: The POS terminal 20 stores the change history information in the change history table 830 (see FIG. 15), and proceeds to step S17 in FIG.
Step S80: The POS terminal 20 refers to the change history table 830 and determines whether change history information is stored. If the POS terminal 20 does not store the change history information, it proceeds to step S17 in FIG. On the other hand, if change history information is stored in the POS terminal 20, the process proceeds to step S81.

Step S81: The POS terminal 20 compares the product information to be subtracted with the change history information, and stores the change history information having common product information (product name and size) other than the sales plan in the change history table 830. Determine whether or not The POS terminal 20 compares the product information to be subtracted with the change history information, and finds that the change history table 830 does not store any change history information having common product information (product name and size) other than the sales plan. If so, the process proceeds to step S17 in FIG. The POS terminal 20 compares the product information to be subtracted with the change history information, and stores the change history information having common product information (product name and size) other than the sales plan in the change history table 830. If so, the process proceeds to step S82.
