Description

The present invention relates to a product sales data processing device and program.

Mass retailers, convenience stores, supermarkets, and the like generally have fewer clerks during times when there are fewer customers (early morning, late at night, etc.) than during times when there are more customers, from the viewpoint of operational efficiency. Therefore, when a clerk is performing a predetermined task (for example, stocking up products, picking up discarded products, etc.) during a time period when there are few customers, the response to the customer tends to be delayed. You may have to wait. On the other hand, a fully self-service POS cash register where the customer pays (registers and settles the merchandise) by himself/herself is gradually becoming popular so that the intervention of the store clerk is not necessary. There has also been proposed a ticket issuing machine for issuing tickets and exchange tickets for tickets (see, for example, Patent Document 1).

JP 2015-049682 A

However, for example, even if a full self-service POS register is introduced in order to improve operational efficiency, it will not be possible to purchase products that require the intervention of a store clerk (for example, products that require age authentication such as alcoholic beverages and cigarettes, oden, frankfurters, etc.). When a customer purchases an unwrapped product, a product that is not displayed on a general display shelf, such as a gift, the customer is forced to wait in front of the register until a store clerk comes to the front of the register. There is

(Outline of each operation mode)
Next, operation modes of the POS terminal 20 will be described. The POS terminal 20 has multiple operating modes. Specifically, the POS terminal 20 has four types of operation modes (normal mode, full self mode, double scan mode, semi self mode). The operation modes described below are the operation modes during normal business (operation modes related to product registration processing and accounting processing). It does not include the maintenance mode for setting work or maintenance work, or the training mode for training newcomers.

5 to 8 are diagrams for explaining the outline of the operation modes of the POS terminal. FIG. 5 is a diagram for explaining the outline of the normal mode. FIG. 5A is a schematic diagram showing the flow of processing (merchandise registration processing, accounting processing) and the actions of people (staff, customers) in the normal mode, and FIG. 4 is a flow chart showing a basic flow of operation; FIG. 6 is a diagram for explaining the outline of the full-self mode. FIG. 6A is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the actions of people (customers) in the full self mode, and FIG. 4 is a flow chart showing a basic flow of operation; FIG. 7 is a diagram for explaining the outline of the double scan mode. FIG. 7A is a schematic diagram showing the flow of processing (merchandise registration processing, accounting processing) and the actions of people (customers) in the double scan mode, and FIG. 4 is a flow chart showing a basic flow of operation; FIG. 8 is a diagram for explaining the outline of the semi-self mode. FIG. 8(A) is a schematic diagram showing the flow of processing (product registration processing, accounting processing) and the actions of people (customers) in the semi-self mode, and FIGS. 8(B) and 8(C) in the semi-self mode 4 is a flowchart showing a basic flow of operations of the POS terminal 20;

In the following description, the mode in which the POS terminal 20 performs product registration processing is referred to as a registration mode, and the mode in which payment processing is performed is referred to as a checkout mode, as a different approach from the above-described four operation mode classifications. There is

(normal mode)
The normal mode, as shown in FIG. 5A, is an operation mode in which the store clerk executes registration processing and the customer executes settlement processing. That is, as shown in FIG. 5B, in the normal mode, the store clerk side enters the registration mode and the customer side enters the checkout mode. In other words, the POS terminal 20 operates in the registration accounting mode from the registration process to the settlement process as a whole.

In the normal mode, the clerk registers the purchased product of the customer on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, the POS terminal 20 executes the registration process of the purchased product according to the operation of the store clerk (the operation of the store clerk side scanner unit 212, the store clerk side display unit 210, the key operation unit 211, etc.) (upper part of FIG. 5A). .

When the registration process by the clerk is completed, the customer confirms the total amount of purchased commodities on the clerk-side display unit 210, inserts money into the change machine 209, or operates the card payment unit 208 to settle the account (FIG. 5). (A) lower row). That is, the POS terminal 20 executes the settlement process according to the customer's operation (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 5A).

That is, in the normal mode, as shown in FIG. 5B, the product is first scanned by the store clerk, for example, by the store clerk scanner unit 212 (step S10: YES), and the product is registered (step S11). After pressing the subtotal key (for example, the subtotal key displayed on the clerk-side display unit 210 or the subtotal key arranged on the key operation unit 211, etc.) (step S30: YES), for example, the change machine 209 is performed (step S50), and the process is completed.

The customer may wait until the store clerk completes the registration process (until the total amount is determined), but may insert money into the change machine 209 before the registration process is completed. That is, the POS terminal 20 can accept payment during the registration process (upper part of FIG. 5A).

In addition, the salesclerk may wait until the customer completes the payment (until the customer obtains change or a receipt), or may register the next customer's purchased product. In other words, the POS terminal 20 can register the purchased product of the next customer during the checkout process (lower part of FIG. 5A). Also, the clerk may be absent during the payment by the customer (lower part of FIG. 5(A)). In other words, the reception of the customer may be finished during the payment of the customer.

In addition, when there is change, the POS terminal 20 controls the dispensation of change or bills by the change machine 209 in order to prevent forgetting to take the change, and a sensor or the like detects that the customer has removed the change or bills. After recognizing the above, the receipt issuance by the customer side printing unit 207 is controlled. The same applies to other operation modes. As described above, in the normal mode (the same applies to the double scan mode), there may or may not be a clerk in front of the customer who receives the change. (That is, the payment of change/change and the receipt may be issued at the same time, or the receipt may be issued first). Further, the timing of paying out change/tills and issuing receipts may be controlled according to the current operation mode and the presence/absence of a clerk (for example, the presence/absence of a clerk is recognized by a sensor).

(Full self mode)
As shown in FIG. 6A, the full self mode is an operation mode in which the customer performs registration processing and the customer performs settlement processing. That is, as shown in FIG. 6B, in the case of the full self mode, the customer side becomes both the registration mode and the checkout mode. In other words, the POS terminal 20 operates in the registration accounting mode from the registration process to the settlement process as a whole.

In the case of the full self mode, the customer registers the purchased product on the customer side (customer side scanner section 206, customer side display section 205). That is, the POS terminal 20 executes registration processing of the purchased product by the customer's operation (scanning by the customer-side scanner unit 206, touching the customer-side display unit 205) (upper part of FIG. 6A).

When the registration process is completed, the customer confirms the total amount of purchased products on the customer-side display unit 205, inserts money into the change dispenser 209, or operates the card payment unit 208 to settle the account (Fig. 6 (A) ) below). That is, the POS terminal 20 executes the settlement process according to the customer's operation (insertion of money into the change machine 209, operation of the card payment unit 208) (lower part of FIG. 6A).

That is, in the full-self mode, as shown in FIG. 6B, the product is scanned by the customer-side scanner unit 206 on the customer side (step S20: YES), and the product is registered (step S21). After the registration completion key (for example, the registration completion key displayed on the customer-side display unit 205) is pressed (step S40: YES), the customer's account is settled by, for example, the change machine 209 (step S50), and processing is performed. is completed.

In the full-self mode, as described above, the customer side executes both the registration process and the settlement process, but this does not mean that the store clerk cannot do anything. That is, even when the POS terminal 20 is operating in the full self mode, the clerk-side scanner unit 212 can scan the clerk code. Further, the POS terminal 20 can display various information (for example, the list described in FIG. 15) on the clerk-side display section 210 even when operating in the full-self mode.

(double scan mode)
The double scan mode, as shown in FIG. 7A, is an operation mode in which registration processing is executed on both the store clerk side and the customer side, and settlement processing is executed on the customer side. That is, as shown in FIG. 7B, in the case of the double scan mode, both the clerk side and the customer side are in the registration mode, and the customer side is in the checkout mode. In other words, the POS terminal 20 operates in the registration accounting mode from the registration process to the settlement process as a whole.

In the case of the double scan mode, the clerk registers the purchased product on the clerk side (clerk side scanner unit 212, clerk side display unit 210, key operation unit 211), and the customer registers the purchased product on the customer side (customer side scanner unit 211). 206, customer-side display unit 205). That is, the POS terminal 20 can be operated by a clerk (scanning by the clerk-side scanner unit 212, touching the clerk-side display unit 210, pressing the key operation unit 211, etc.) and by a customer (customer-side scanner unit 206). , and touch on the customer-side display unit 205), the registration processing of the purchased product is executed (upper part of FIG. 7A).

When the registration process is completed, the customer confirms the total amount of purchased products on the customer-side display unit 205, inserts money into the change machine 209, or operates the card settlement unit 208 to settle the account (Fig. 7 (A) ) below). That is, the POS terminal 20 executes the settlement process according to the customer's operation (insertion of money into the change machine 209, operation of the card settlement unit 208) (lower part of FIG. 7A).

That is, in the double scan mode, products are first registered on the store clerk side and the customer side. For example, as shown in FIG. 7B, by scanning the store clerk side scanner unit 212 (step S10: YES), goods are registered (step S11), and by scanning the customer side scanner unit 206 (step S20: YES), the product is registered (step S21). A subtotal key (for example, a subtotal key displayed on the clerk-side display unit 210 or a subtotal key arranged on the key operation unit 211) or a registration completion key (for example, a registration completion key displayed on the customer-side display unit 205) After the completion key, etc.) is pressed (step S41: YES), on the customer side, the payment is made by, for example, the change dispenser 209 (step S50), and the process is completed.

The store clerk may wait until the customer completes the payment (until the customer obtains change or a receipt), or may register the next customer's purchased product. In other words, the POS terminal 20 can register the purchased product of the next customer during the checkout process (lower part of FIG. 7A). Also, the clerk may be absent during the payment by the customer (lower part of FIG. 7(A)). In other words, the reception of the customer may be finished during the payment of the customer.

(Semi-self mode)
The semi-self mode is an operation mode using two or more POS terminals 20. As shown in FIG. 8A, at least one POS terminal 20 (POS terminal 20-1 in the example of FIG. , and the customer side of another POS terminal 20 (one of the POS terminals 20-2 and 20-3 in the example of FIG. 8) executes the settlement process. mode. That is, in the case of the semi-self mode, one or more terminals (in the example of FIG. 8, one of the POS terminals 20-1 as shown in FIG. 8B) enters the registration-only mode, and one or more other terminals (the In an example, as shown in FIG. 8(C), two POS terminals 20-2 and 20-2) are in the checkout mode.

In the semi-self mode, the clerk registers the purchased product of the customer at the POS terminal 20 in the registration-only mode on the clerk side (clerk side scanner section 212, clerk side display section 210, key operation section 211). In other words, the POS terminal 20 executes the registration process of the purchased product according to the operation of the store clerk (the operation of the store clerk side scanner unit 212, the store clerk side display unit 210, the key operation unit 211, etc.) (upper part of FIG. 8A). .

When the registration processing by the clerk is completed, the customer moves to the POS terminal 20 in the checkout-only mode, confirms the total amount of purchased commodities on the clerk-side display unit 210, inserts money into the change machine 209, or performs card payment. Operate the unit 208 to settle (lower part of FIG. 8(A)). In other words, the POS terminal 20 executes settlement processing according to the customer's operation (insertion of money into the change machine 209, operation of the card payment unit 208) (lower part of FIG. 8A).

When the registration process is completed at the POS terminal 20 in registration-only mode (POS terminal 20-1 in the example of FIG. Then, it moves to the POS terminal 20-2), and the POS terminal 20 at the destination is supplied with information necessary for settlement processing (registration information generated at the POS terminal 20 in the registration-only mode, etc.).

The destination POS terminal 20 (of the POS terminals 20 in accounting-only mode, the POS terminal 20 that executes the settlement process) may be specified in the POS terminal 20 in registration-only mode. Alternatively, the POS terminal 20 in registration-only mode issues a medium (a medium on which a barcode or the like for obtaining information necessary for settlement processing is printed), and the POS terminal 20 in accounting-only mode that reads the medium is used. It may be the POS terminal 20 at the destination.

In other words, in the semi-self mode, the product is first registered by the store clerk of the POS terminal 20 (POS terminal 20-1) in the registration-only mode. For example, as shown in FIG. 8B, products are registered (step S11) by scanning with the clerk side scanner unit 212 (step S10: YES). After pressing the subtotal key (for example, the subtotal key displayed on the clerk-side display unit 210 or the subtotal key arranged on the key operation unit 211) (step S30: YES), for example, the POS terminal 20 in accounting mode ( (one of the POS terminals 20-3 of the POS terminal 20-2) is specified (step S31: YES), the registration information is transmitted to the specified POS terminal 20 (step S32), and the POS in the registration-only mode Processing in the terminal 20 is completed.

Subsequently, as shown in FIG. 8C, after receiving the registration information (step S49: YES), the POS terminal 20 in accounting-only mode (that is, the POS terminal 20 specified by the POS terminal 20 in registration-only mode) In the case of the customer, the payment is made by, for example, the change machine 209 (step S50), and the processing at the POS terminal 20 in the payment-only mode is completed.

After transmitting the registration information, the store clerk can register the next customer's purchased product (lower part of FIG. 8(A)). Also, the clerk may be absent after transmitting the registration information (lower part of FIG. 8(A)).

(Notification of operation mode)
The POS terminal 20 notifies the current operating mode. For example, the current operation mode may be displayed on the store clerk's display unit 210 . Specifically, a screen having an operation mode display column may be displayed on the clerk-side display unit 210, and the current operation mode may be displayed in the operation mode display column on the screen. Also, a screen on which an image corresponding to each operation mode (for example, a button-like image) is arranged is displayed on the clerk's side display unit 210, and an image corresponding to the current operation mode is displayed on the screen. It may be displayed in a display manner different from that of the non-corresponding image (for example, in a display manner that is more conspicuous than the display manners of other images). Note that the customer-side display unit 205 may similarly display the operation mode.

Also, the POS terminal 20 may notify information according to the current operation mode. For example, the customer-side display unit 205 may display a message corresponding to the current operation mode. Specifically, if the current operation mode is full self mode, for example, when the customer is waiting, the customer himself/herself will be asked to register the product (message such as "Please scan the customer"). It may be displayed on the customer-side display unit 205 (for example, scroll display in large characters).

(Transition of operation mode)
Next, transition (switching) of the operation mode of the POS terminal 20 will be described. The POS terminal 20 changes the operation mode according to an explicit mode change operation (input on the operation mode setting screen, operation of the operation mode setting button, etc.) by the clerk. In addition, the POS terminal 20 changes the operation mode according to another operation (for example, reading a salesclerk code, etc.) other than the explicit mode switching operation by the salesclerk. In addition, the POS terminal 20 can be set under certain conditions that are not dependent on the operation of a store clerk (conditions related to time such as elapsed time and predetermined time (schedule), conditions related to transmission/reception of information such as instructions to/from other terminals, etc.). ), the operation mode is changed.

9 and 10 are diagrams for explaining an example of operation mode transition. FIG. 9A is a flowchart showing the flow of transition from normal mode to full self mode. FIG. 9B is a flow chart showing the flow of transition from full self mode to double scan mode. FIG. 10A is a flow chart showing the flow of transition from normal mode to semi-self mode (registration-only mode). FIG. 10B is a flow chart showing the flow of transition from the normal mode to the semi-self mode (accounting mode).

(Transition from normal mode to full self mode)
The flowchart of FIG. 9A starts when the POS terminal 20 (normal mode) is not in use (that is, when neither the store clerk nor the customer uses it).

Step S100: Start counting non-use time.
Step S101: Judge whether or not the store clerk or customer has started to use the product. If the use has not started, the process proceeds to step S102. When the use is started, the process proceeds to step S104.

Step S102: Determine whether or not the non-use time has passed a predetermined time (for example, preset 10 minutes). If the predetermined time has passed, the process proceeds to step S103. If the predetermined time has not elapsed, the process returns to step S101.
Step S103: Change the operation mode from the normal mode to the full self mode.
Step S104: Terminate the clocking of non-use time. Then, the flowchart of FIG. 9A ends.

In addition, when the shift to the full-self mode is made, the clerk may be notified of the shift to the full-self mode (for example, information indicating that there are undelivered products may be transmitted to the terminal carried by the clerk). . Further, when shifting to the full self mode, the customer side display section 205 may display a message instructing or requesting the customer to perform self registration.

Note that FIG. 9A shows the flow regarding the transition from the normal mode to the full self mode, and the transition from the double scan mode to the full self mode is similar to the flow of FIG. may be

(Transition from full self mode to double scan mode)
The flowchart of FIG. 9B always starts (regularly at very short time intervals) in the POS terminal 20 (full self mode).

Step S110: It is determined whether or not the clerk-side scanner unit 212 has read the clerk code. If the salesclerk code is read, the process proceeds to step S111. If the store clerk code has not been read, the flow chart of FIG. 9B ends.

Step S111: Transition the operation mode from the full self mode to the double scan mode. Then, the flowchart of FIG. 9B ends.

(Transition from normal mode to semi-self mode (registration-only mode))
The flowchart of FIG. 10A always starts (regularly at very short time intervals) in the POS terminal 20 (normal mode).

Step S120: It is determined whether or not there is an operation to declare a shift to the semi-self mode (registration-only mode). For example, a button for declaring a transition to the semi-self mode (registration-only mode) may be displayed on the clerk-side display unit 210, and whether or not the button has been pressed (touched) may be determined. If there is an operation, the process proceeds to step S121. If there is no operation, the flow chart of FIG. 10(A) ends.

Step S121: It is determined whether there is another POS terminal 20 operating in the semi-self mode in the POS system 1 or not. As described above, in the semi-self mode, one or more POS terminals 20 in the registration-only mode and one or more POS terminals 20 in the accounting-only mode are required. , POS terminals 20-2 and 20-3 are operating in a semi-self mode (registration-only mode) and the other is operating in a semi-self mode (accounting-only mode). If there is no other POS terminal 20 operating in the semi-self mode, the process proceeds to step S122. If there is another POS terminal 20 operating in the semi-self mode, the process proceeds to step S124.

Step S122: It is determined whether or not another POS terminal 20 to be shifted to the semi-self mode (accounting mode) has been specified. If there is designation, the process proceeds to step S123. If there is no designation, the process of step S122 is repeated.
Step S123: An instruction to shift to the semi-self mode (accounting mode) is transmitted to the designated other POS terminal 2. FIG.

Step S124: Determine whether processing is in progress. If it is not being processed, the process proceeds to step S125. If the processing is in progress, the processing of step S124 is repeated.
Step S125: The operation mode is shifted from the normal mode to the semi-self mode (registration-only mode). Then, the flowchart of FIG. 10A ends.

Note that the operation of step S120 is performed when there is no other POS terminal 20 already operating in the semi-self mode and when there is no other POS terminal 20 capable of shifting to the semi-self mode. should not be allowed.

(Transition from normal mode to semi-self mode (accounting mode))
The flowchart of FIG. 10B always starts (regularly at very short time intervals) in the POS terminal 20 (normal mode).

Step S130: Determine whether or not an instruction to shift to the semi-self mode (accounting mode) has been received. When the transfer instruction is received, the process proceeds to step S131. If no transfer instruction has been received, the flow chart of FIG. 10B ends.

Step S131: Determine whether processing is in progress. If not in process, the process proceeds to step S132. If it is in process, the process of step S131 is repeated.
Step S132: The operation mode is shifted from the normal mode to the semi-self mode (accounting exclusive mode). Then, the flowchart of FIG. 10B ends.

FIG. 10(B) shows the flow of transition from normal mode to semi-self mode (accounting mode). 10(B) flow may be the same.

(Registration of specific products in full self mode)
A specific product is a product that requires the intervention of a store clerk. For example, products that require age verification when sold (e.g. alcoholic beverages, cigarettes, etc.), products that require packaging work when sold (e.g., oden, frankfurters, etc.) Specific products include products that are sold by a company (for example, cigarettes, stamps, expensive gifts, etc.). In addition, services such as payment of utility bills, parcel delivery service (application, pick-up), etc., are also included in the specific products because they involve sales clerks. In addition, sales of various tickets for concerts, reservations for presents (Mother's Day, etc.), ordered products (New Year's dishes, etc.), game software, etc., require information (applicant, delivery address, etc.) If it is necessary to enter, it corresponds to a specific product. In addition, pharmaceuticals and the like that require product explanations by a salesclerk who is a pharmacist also correspond to specific products regardless of the display position. Whether or not each product corresponds to a specific product is stored in the product master or the like. Further, whether or not individual products require age authentication may be stored in the product master or the like.

Full self mode is originally an operation mode prepared for customers to register products and make payments without the intervention of a store clerk. Operation will be explained.

FIG. 11 shows a display example on the customer-side display unit 205. As shown in FIG. In the case of the full-self mode, the customer uses the customer-side scanner unit 206 or operates the customer-side display unit 205 to execute registration processing of the purchased product. A customer may display a registration screen (registration screen dedicated to a specific product) as shown in FIG. 11 in order to register the specific product.

For example, the customer-side display unit 205 initially displays a registration screen for general products that do not correspond to specific products, and when a predetermined operation is performed (for example, when a predetermined button is pressed on the registration screen for general products) case, etc.), a registration screen dedicated to a specific product may be displayed. General products are products that do not require the intervention of a store clerk (products that can be picked up by customers from display shelves). On the registration screen for general products, preset keys corresponding to products without barcodes (for example, fruits) may be displayed, although they can be picked up from the display shelf without the help of a store clerk. .

In FIG. 11, tab TB1 classifies specific products by group. The tab TB2 is obtained by further classifying the specific products in the group selected on the tab TB1 into small groups. IM is a list display of individual specific products in the small group selected on the tab TB2 using images and the like. PU is a pop-up screen (small screen) for designating the purchase quantity and the like for one specific product selected from the list display. MG is a customer-oriented message.

In the example shown in FIG. 11, the customer selects "tobacco" on the tab TB1, selects the brand "star 4" on the tab TB2, selects "1mm" in the "star 4" series on the IM, and pops up A scene in which one (“piece” “1”) is selected on the screen PU is shown. When the button "confirm purchase" in the pop-up screen PU is pressed from the state shown in FIG. 11, one "star 4 (1 mm)", which is the specific product, is registered. As shown in FIG. 11, cigarettes can also be specified (purchased) in cartons.

In FIG. 11, the tabs have two hierarchies (tab TB1 and tab TB2), but they may have one hierarchy or three or more hierarchies. For example, individual specific commodities (chikuwa, kelp, eggs, etc.) may be listed by images or the like under the tab TB1 "Oden" without providing the tab TB2 under the tab TB1 "Oden".

In addition, as a method of specifying cigarettes (purchase method), individual products ("Star 4 (1 mm)", "Star 4 (2 mm)", ... "Lucky Man (1 mm), etc." Numbers attached to cigarette racks, etc.) may be directly designated, and other specific commodities may also be directly designated by numbers or the like.

The screen shown in FIG. 11 is a registration screen dedicated to specific products, but a registration screen that allows registration of both specific products and general products may be displayed on the customer-side display unit 205 .

FIG. 12 is a flow chart showing an example of the operation when registering a specific product. The flow chart of FIG. 12 always (periodically at very short time intervals) starts at the POS terminal 20 (full self mode).

Step S200: Determine whether or not the product has been scanned. That is, it is determined whether or not the product has been scanned by the customer-side scanner unit 206 or the customer-side display unit 205 has been operated. If the product has been scanned, the process proceeds to step S201. If the product has not been scanned, the process proceeds to step S207.

Step S201: Register the product.
Step S202: Judge whether or not the registered product is a specific product. If the product is a specific product, the process proceeds to step S205. If the product is not a specific product, the process proceeds to step S207.

Step S205: Manage the registered specific product as "undelivered product". For example, in the specific product delivery management information for managing the delivery of the specific product, the registered specific product is stored as an undelivered product. An undelivered product is a product that has not yet been delivered to the customer (a product that the customer has not yet received).
Step S206: Notify the clerk that there are undelivered products. For example, information indicating that there are undelivered products may be transmitted to a terminal carried by the store clerk. Note that the fact that the salesclerk has been notified (for example, a message such as "The salesclerk is being called") may be displayed on the customer-side display section 205 (or the customer-side display section 205 and the salesclerk-side display section 210). The same applies to step S306 in FIG.

Step S207: Determine whether or not there are undelivered products. Specifically, if no specific products have been registered, or if one or more specific products have been registered but all registered specific products have already been delivered, undelivered products judge not. On the other hand, if one or more specific products are registered and some or all of the registered specific products have not been delivered, it is determined that there are undelivered products. If there are undelivered commodities, the process proceeds to step S208. If there is no undelivered product, the process proceeds to step S211.

Step S208: Display a list of undelivered products on the clerk side display section 210. FIG.
Step S209: It is determined whether or not an undelivered product has been specified (touched) in the list of undelivered products. In other words, it is determined whether or not the clerk has confirmed the undelivered product in the list (confirmation before or after delivery of the undelivered product to the customer), that is, whether or not the undelivered product has been delivered to the customer. If the undelivered product is specified, the process proceeds to step S210. If there is no designation of undelivered goods, the process proceeds to step S211.
Step S210: Set the designated undelivered product as delivered. For example, in the specific product delivery management information, the specified specific product is stored as a "delivered product". Although the details will be described later, for example, the delivery classification "1 (undelivered)" in FIG. 14 is changed to the delivery classification "2 (delivered before issuance)". A delivered product is a product that has already been delivered to the customer (a product that the customer has already received).

Step S211: Determine whether or not registration of all products to be purchased has been completed. That is, it is determined whether or not a registration completion key (for example, a registration completion key displayed on the customer-side display unit 205) has been pressed. If all products have been registered, the process proceeds to step S214. If not completed, the process returns to step S200.
Step S214: Settle.
Step S215: The customer side printing unit 207 issues a receipt. Note that a receipt may be issued on which the undelivered product is printed so as to be distinguishable from other products. For example, undelivered products may be marked with an asterisk, an asterisk, or the like, underlined, or the like.

Step S216: Determine whether or not there are undelivered products. If there are undelivered commodities, the process proceeds to step S217. If there are no undelivered commodities, the flow chart of FIG. 12 ends.
Step S217: The customer-side printing unit 207 issues (issues) an exchange ticket for the undelivered product. In addition, when an exchange ticket is issued, the fact that the exchange ticket will be issued and the number of issued tickets will be displayed on the customer's side before the exchange ticket is issued (specifically, before the receipt is issued). The store clerk may be made aware of this by means of display or voice by the unit 205 .
Step S218: Store that the exchange ticket has been issued. For example, in the specific product delivery management information, it is stored that an exchange ticket has been issued for a product for which an exchange ticket has been issued. Although the details will be described later, for example, the ticket issue category “0 (unissued)” in FIG. 14 is changed to the ticket issue category “1 (issued)”. It also stores the exchange ticket number and ticket issue time.

Step S219: Notify the clerk that the exchange ticket for the undelivered product has been issued. For example, information to the effect that an exchange ticket for an undelivered product has been issued may be transmitted to a terminal carried by a store clerk. The flowchart of FIG. 12 then ends. Note that the fact that the salesclerk has been notified (for example, a message such as "The salesclerk is being called") may be displayed on the customer-side display section 205 (or the customer-side display section 205 and the salesclerk-side display section 210). It should be noted that, in the process of step S206, if the customer-side display unit 205 displays the fact that the salesclerk has been notified, it does not have to be displayed again in the process of step S219. The same applies to step S319 in FIG.

FIG. 13 is an example of registration information. For example, as shown in FIG. 13, the registration information stores transaction number, transaction date and time, product code, product name, unit price, quantity, and specific product category. The transaction number is a number that identifies the transaction. The specific product category is information indicating whether or not the product is a specific product. The specific product category "0" indicates that the product is a general product that does not correspond to the specific product, and the specific product category "1" indicates that it is a specific product.

When the first product is scanned, the POS terminal 20 stores the transaction number, date and time, and information about the first product (product code, product name, unit price, quantity, specific product classification), and thereafter , each time the second and subsequent products are scanned, information on each product (product code, product name, unit price, quantity, specific product category) is stored.

As for the registration information shown in FIG. 13, in step S201 of FIG. 12, "Japanese-style large serving yakisoba A" with product code "SC1111" is registered, followed by "Star 4 (1 mm)" with product code "SC1023". Then, "B mountain natural water (1.5 L)" with product code "SC4788" is registered, then "Special Frankfurt" with product code "SC5555" is registered, and then product code "SC3620" is registered. is an example of registration information generated when "C chocolate" of is registered.

Also, the registration information shown in FIG. 13 is an example as described above, and in place of or in addition to each information (registration number, transaction date, product code, etc.) shown in FIG. You can remember. For example, the operation mode may be stored as registration information. As an example, the operation mode "01" is stored for the normal mode, the operation mode "02" is stored for the full self mode, the operation mode "03" is stored for the double scan mode, In the case of the semi-self mode, the operation mode "04" may be stored. Also, as the registration information, a product registrant (operator) may be stored. As an example, if a store clerk registers, a store clerk code may be stored as a product registrant, and if a customer registers, a predetermined code (for example, "9999", etc.) indicating registration by the customer may be stored. For example, in the case of the registration information of FIG. 13, even if the operation mode "02 (full self mode)" and the product registrant "customer (9999)" are stored between the transaction date and time "YYMMDDHHMM" and the product code "SC1111", good. In the case of registration by a customer who is a member, the member number may be stored instead of "9999".

Also, as the registration information, an age certification category may be stored. As an example, if the product does not require age verification, the age verification category “00” is stored, and if the product requires age verification but has not yet been authenticated, the age verification category “01” is stored and the age If the product does not require authentication and has already been authenticated, the age authentication category "02" may be stored. For example, for each product, the age verification category may be stored next to the specific product category. As another example, the age verification category "0" may be stored when age verification is not performed, and the age verification category "1" may be stored when age verification is performed. Note that the former (a form of storing any of “00 (age authentication not required)”/“01 (age authentication required/unauthenticated)”/“02 (age authentication required/authenticated)”) is a This is an example of managing in units. The latter (mode of storing either "0 (no age verification)"/"1 (age verification)") is an example of managing age verification on a per-transaction basis.

Assuming that the operation mode changes during one transaction, the operation mode may be stored for each product. Also, assuming a double scan mode or the like, the product registrant may be stored for each product.

FIG. 14 is an example of specific product delivery management information. Specific product delivery management information includes, for example, transaction number, product code, delivery classification, ticket issue classification, exchange ticket number, as shown in FIG. Stores ticket issuing time and exchange time.

The delivery category is information indicating whether or not the product (specific product) has been delivered to the customer. Delivery category "1" indicates undelivered, delivery category "2" indicates that delivery has been completed before issuance (i.e., delivery has been completed before the issuance of a voucher (i.e., before settlement)), and delivery category "3" indicates that after issuance. Indicates "delivered" (delivered after the exchange ticket is issued (that is, after settlement)). The issue classification is information indicating whether or not an exchange ticket has been issued (issued) for the product (the specific product). The ticket issue category "0" indicates that the ticket has not yet been issued (no ticket issued), and the ticket issue category "1" indicates that the ticket has been issued (issued). The exchange ticket number is a number for distinguishing the exchange ticket for the product (the specific product) from other exchange tickets. The ticket issuing time is the time when the exchange ticket for the product (the specific product) is issued. The exchange time is the time when the product (specific product) is exchanged. In other words, it is the time when the specific product is handed over to the customer using the exchange ticket for the product (the specific product).

For example, in step S205 of FIG. 12, the POS terminal 20 generates specific product delivery management information such as the delivery category "1 (undelivered)" and the ticket issue category "0 (unissued)". Also, the POS terminal 20 changes the delivery class "1 (undelivered)" to the delivery class "2 (delivered before issuance)" in step S210 of FIG. 12, for example. 12, the POS terminal 20 changes the ticketing classification "0 (unissued)" to the ticketing classification "1 (issued)" and stores the exchange ticket number and the ticketing time. 18 (described later), the POS terminal 20 changes the delivery classification "1 (undelivered)" to the delivery classification "3 (delivered after issuance)" and stores the delivery time.

Note that the specific product delivery management information shown in FIG. 14A indicates that the specific product (star 4 (1 mm)) with the product code “SC1023” has not yet been delivered, and that no exchange ticket has been issued. , indicates that the specific product (special frankfurter) with the product code “SC5555” has not yet been delivered, and that an exchange ticket has not yet been issued. In other words, it indicates that the delivery to the customer has not been completed for the above two specific commodities, although the exchange ticket has not yet been issued.

The specific product delivery management information shown in FIG. 14B indicates that the specific product (star 4 (1 mm)) with the product code “SC1023” has not yet been delivered and that an exchange ticket has been issued. It indicates that the specific product (special frankfurter) with the code "SC5555" has not yet been delivered and that the exchange ticket has already been issued. In other words, it indicates that exchange tickets for the above two specific products have already been issued and delivery to customers has not been completed.

The specific product delivery management information shown in FIG. 14C indicates that the specific product (star 4 (1 mm)) with the product code “SC1023” has been delivered to the customer before the issuance of the voucher (before payment). , indicating that the specific product (special frankfurter) with the product code “SC5555” has been handed over to the customer after the exchange ticket is issued.

In addition, in the specific product delivery management information, information (for example, time of notification, etc.) related to the performance of notification to the clerk may be stored.

FIG. 15 shows an example of display on the store clerk's display unit 210 . The POS terminal 20 displays, for example, a list of undelivered products as shown in FIG.

FIG. 15(A) is a list of undelivered products based on the specific product delivery management information of FIG. 14(A). In other words, it indicates that the two specific products (star 4 (1 mm) and special frankfurter) have not yet been delivered to the customer, although the exchange ticket has not yet been issued.

FIG. 15(B) is a list of undelivered products based on the specific product delivery management information of FIG. 14(B). In other words, it indicates that exchange tickets have already been issued for two specific products (star 4 (1 mm) and special frankfurter), and delivery to customers has not been completed.

In FIGS. 15A and 15B, tab TB is a tab for selecting a transaction (customer). FIG. 15(A) shows a state in which only the tab of the customer who is being registered exists and is selected. FIG. 15(B) shows a tab for a customer who is being registered (a customer following the customer in FIG. 15(A)) and a tab for a customer after payment (the customer in FIG. 15(A)). tab is selected. In addition, on the customer's tab after payment, the exchange ticket number of the exchange ticket issued to the customer (if multiple exchange tickets are issued, one exchange ticket number as shown in FIG. 15B) is displayed. ing.

In FIG. 15(B), area A is an area for notifying that an exchange ticket has been issued. In FIGS. 15A and 15B, area B is a display area for undelivered products. Area C is an area for displaying the name of the undelivered merchandise, and area D is an area for displaying the registered number of undelivered merchandise (undelivered number). In FIG. 15B, area E is an area for displaying the exchange ticket number of the exchange ticket for the undelivered product.

FIG. 16 is an example of an exchange ticket. For example, in step S217 of FIG. 12, the POS terminal 20 issues (issues) an exchange ticket for the undelivered product as shown in FIG.

FIG. 16(A) is an exchange ticket for the specific product (star 4 (1 mm)) with the product code "SC1023" of the specific product delivery management information in FIG. 14(B). A bar code (symbol BC) that encodes the exchange ticket number "H345" of the exchange ticket is printed on the exchange ticket of FIG. 16(A).
FIG. 16(B) is an exchange ticket for the specific product (special frankfurter) with the product code "SC5555" of the specific product delivery management information in FIG. 14(B). A bar code (symbol BC) that encodes the exchange ticket number "H346" of the exchange ticket is printed on the exchange ticket of FIG. 16(B).

The POS terminal 20 issues one exchange ticket as shown in FIG. 16(C) instead of issuing the exchange ticket shown in FIG. 16(A) and the exchange ticket shown in FIG. 16(B). may A bar code (symbol BC) that encodes the exchange ticket number "H345" and the exchange ticket number "H346" is printed on the exchange ticket of FIG. 16(C).

FIG. 17 shows an example of display on the clerk-side display section 210 of another POS terminal 20. FIG. When a certain POS terminal 20 issues an exchange ticket, other POS terminals 20 can display information about the exchange ticket. For example, as shown in FIG. 17, the other POS terminal 20 may display the exchange ticket number, the POS terminal 20 that issued the exchange ticket, and the elapsed time after issuance as information about the exchange ticket.

The screen shown in FIG. 17 is a registration screen having an exchange ticket notification area HJ for notifying information about the exchange ticket. In the exchange ticket information area HJ, the number of exchange tickets (the number of exchange tickets before delivery of the product), the exchange ticket number as information on each exchange ticket, the POS terminal 20 of the issuer, and the elapsed time after issuance are displayed. ing. Specifically, in the exchange ticket notification area HJ, the number of exchange tickets is 3 (symbol HS), and as information on the first exchange ticket, the exchange ticket number "H345" and the issuer's POS terminal 20 "1" are displayed. machine number", and the elapsed time after issuance "2 minutes passed" are displayed (symbol H1). The elapsed time after "2 minutes passed" is displayed (symbol H2), and the information about the third exchange ticket includes the exchange ticket number "H348", the POS terminal 20 of the issuer "Unit 3", and the elapsed time after issuance "Before 1 minute has passed" is displayed (symbol H3). At the bottom, the current mode (normal mode) is reported (symbol M).

The first machine is, for example, the POS terminal 20-1, and the third machine is, for example, the POS terminal 20-3. The registration screen in FIG. 17 is displayed, for example, on the second machine (for example, the POS terminal 20-2).

In the example shown in FIG. 17, a plurality of exchange tickets are displayed from the top in descending order of elapsed time after issuance (in ascending order of customer waiting time). Note that the display mode may be changed according to the elapsed time. For example, when the elapsed time is less than 1 minute, the text and background are normal color (e.g., light blue), and when the elapsed time is 1 minute or longer and less than 2 minutes, the text and background are set to caution color (e.g., yellow). When the elapsed time is two minutes or more, the characters and background may be colored in a color (for example, red) that urges urgent action.

When there is no exchange ticket (exchange ticket before delivery of the product), the exchange ticket notification area HJ itself does not have to be displayed on the registration screen. In other words, when the exchange ticket no longer exists (when the product on the exchange ticket is handed over), the exchange ticket notification area HJ itself may be hidden. Further, when an exchange ticket exists (when an exchange ticket is issued by another POS terminal 20), the exchange ticket notification area HJ may be automatically displayed on the registration screen, A "exchange coupon available" button or the like may be displayed on the registration screen, and the exchange coupon notification area HJ may be displayed on the registration screen when the button is touched.

Further, display/non-display of the exchange coupon notification area HJ may be switched by an operation. When the exchange ticket notification area HJ is hidden while the exchange ticket exists, the fact that the exchange ticket exists may be displayed (for example, a "exchange ticket present" button may be displayed).

In the lower part of the exchange ticket notification area HJ, a notification button HB for notifying other staff members and a switching button KB for switching information (exchange ticket) to be displayed are arranged.

If there is no information to be switched and displayed, the switch button KB may be disabled and grayed down, or the switch button KB itself may be hidden.

FIG. 17 shows an example of display in the normal mode, but information related to exchange tickets may be similarly displayed on the clerk-side display section 210 in other modes (for example, double scan mode). Also, FIG. 17 shows an example of display on the registration screen, but information on exchange tickets may also be displayed on other screens (for example, standby screens).

In addition, when the fields of each exchange ticket (the fields of H1, H2, and H3) in the exchange ticket notification area HJ are touched (when the relevant exchange ticket is specified), the undelivered ticket corresponding to the relevant exchange ticket is displayed. Information about the product may be displayed. For example, in the exchange ticket notification area HJ, when the exchange ticket column shown in FIG. Information such as that shown in area B in FIG. 15B may be displayed.

In addition, although it has been explained that the information related to the exchange ticket issued by the other terminal is displayed, the information related to the exchange ticket issued by the own terminal may also be displayed. An exchange ticket issued by one's own terminal may be easily distinguished from an exchange ticket issued by another terminal. For example, the words "issued by own terminal" may be displayed. Further, the issuer may be left blank, or may be displayed as "No. 1 machine (own terminal)" or the like.

FIG. 18 is a flow chart showing an example of the operation after issuing an exchange ticket. The flowchart of FIG. 18 starts when there are undelivered commodities at the POS terminal 20 (full self mode). It is assumed that a list of undelivered commodities as shown in FIG. It is also assumed that an exchange ticket has been issued for each undelivered product.

Step S230: Determine whether the bar code of the voucher has been scanned. That is, it is determined whether or not the bar code of the exchange ticket has been scanned by the clerk side scanner unit 212 . After scanning the bar code of the exchange ticket, the clerk delivers the undelivered product of the exchange ticket to the customer, or scans the barcode of the exchange ticket after delivering the undelivered product of the exchange ticket to the customer. Therefore, the determination is whether or not the store clerk has handed over the undelivered product to the customer in exchange for the exchange ticket. If not scanned, the process proceeds to step S231. If scanned, the process proceeds to step S233.

Step S231: It is determined whether or not a predetermined time has passed since the previous (most recent) notification to the store clerk of the transaction (the customer). That is, when the notification in step S232 (described later) of this figure (FIG. 18) has been performed once or more, a predetermined time has elapsed since the notification in step S232 (the most recent notification when performed multiple times). If the notification in step S232 of this figure has not yet been performed, it is determined whether a predetermined time has passed since the notification in step S219 of FIG. If the predetermined time has not passed, the process returns to step S230. If the predetermined time has passed, the process proceeds to step S232.

Step S232: Notify the store clerk that there are undelivered products. For example, information indicating that there are undelivered products may be transmitted to a terminal carried by the store clerk. Then, the process returns to step S230.
Step S233: Set the undelivered product of the exchange ticket as delivered. For example, in the specific product delivery management information, the specified specific product is stored as a "delivered product". Specifically, the delivery classification “1 (undelivered)” is changed to the delivery classification “3 (delivered after issuance)”. It also stores the delivery time. Then the flow chart of FIG. 18 ends.

According to the flowchart of FIG. 18, after the exchange ticket is issued, the clerk is notified that there are undelivered products at predetermined time intervals (that is, at predetermined time intervals). (that is, at regular time intervals). For example, the clerk may be notified when 2 minutes have passed since the issuance of the exchange ticket, the clerk may be notified again when 1 minute has passed, and the clerk may be notified every 30 seconds thereafter.

The flowchart in FIG. 18 is repeatedly executed until there are no more undelivered products for a certain transaction (a customer). case), even after the first exchange ticket is read (even after the clerk delivers the first undelivered product), all exchange tickets must be read within a predetermined time. (Unless all other undelivered products are delivered to the customer), the clerk will be notified any number of times, but the manner of notification may be changed according to how many times the notification is made. Alternatively, the clerk may not be notified after the first exchange ticket for a certain transaction has been read.

The flowchart shown in FIG. 12 shows the operation of immediately registering even if the purchased product is a specific product (see steps S200 to S205 in FIG. 12). may be provisionally registered without immediate registration (main registration). In the flowchart shown in FIG. 12, even if the purchased product is a specific product, the registration is always performed by the customer (although the full self mode is maintained). You may register with (you may shift to double scan mode).

FIG. 19 is a flow chart showing another example of the operation when registering a specific product. The flow chart of FIG. 12 starts at the POS terminal 20 (full self mode) all the time (regularly at very short time intervals).

Step S300: Determine whether or not the product has been scanned. That is, it is determined whether or not the product has been scanned by the customer-side scanner unit 206 or the customer-side display unit 205 has been operated. If the product has been scanned, the process proceeds to step S302. If the product has not been scanned, the process proceeds to step S307.

Step S302: Determine whether the scanned product is a specific product. If the product is not a specific product, the process proceeds to step S303. If the product is a specific product, the process proceeds to step S304.

Step S303: Officially register the product. The official registration is normal registration, and corresponds to the registration in step S201 in FIG. 12, for example. Then, the process proceeds to step S307.

Step S304: Temporarily register the specific product. Temporary registration is a temporary registration state before main registration is performed.
Step S305: The temporarily registered specific product is managed as a "temporarily registered product". For example, as provisionally registered product management information (not shown), the temporarily registered specific product is stored as the provisionally registered product.
Step S306: Notify the store clerk that there is a provisionally registered product. For example, information indicating that there is a provisionally registered product may be transmitted to a terminal carried by a store clerk.

Step S307: Determine whether or not there is a provisionally registered product. Specifically, if there is no specific product, or if one or more specific products have been provisionally registered but all of the provisionally registered specific products have already been officially registered, there is no provisionally registered product. I judge. On the other hand, if one or more specific commodities are provisionally registered and some or all of the provisionally registered specific commodities are not officially registered, it is determined that there are provisionally registered commodities. If there is a provisionally registered product, the process proceeds to step S308. If there is no provisionally registered product, the process proceeds to step S311.

Step S308: Display a list of provisionally registered products on the salesclerk side display section 210. FIG.
Step S309: The store clerk determines whether the provisionally registered product has been scanned. In other words, whether or not there was an operation by the clerk who confirmed the list (scanning of the provisionally registered product by the clerk-side scanner unit 212, operation on the key operation unit 211, operation on the clerk-side display unit 210, double scanning) (that is, Since the provisionally registered product is delivered to the customer by the operation, etc., it is determined whether or not the provisionally registered product has been delivered to the customer.If the provisionally registered product is scanned, etc., the process proceeds to step S310. If the registered product has not been scanned, the process proceeds to step S211.
Step S310: Mainly register the provisionally registered product that has been scanned. For example, in the provisionally registered product management information, the scanned specific product is stored as the "officially registered product".

Step S311: Determine whether or not registration of all products to be purchased has been completed. If all products have been registered, the process proceeds to step S312. If not completed, the process returns to step S300.

Step S312: Determine whether or not there is a provisionally registered product. If there is a provisionally registered product, the process proceeds to step S313. If there is no provisionally registered product, the process proceeds to step S314.
Step S313: The temporarily registered product is officially registered and managed as an undelivered product.

19 are the same as the steps S214 to S219 in FIG. 12, and description thereof will be omitted.

(Clerk side and customer side display in double scan mode)
The double scan mode is a mode in which registration processing is executed on both the store clerk side and the customer side, and the displays on the store clerk side display section 210 and the customer side display section 205 during the registration process will be described below.

FIG. 20 is a flow chart showing an example of the operation when registering a product. The flow chart of FIG. 20 always starts (periodically at very short time intervals) at the POS terminal 20 (double scan mode). Note that the dashed rectangle P will be described later.

Step S400: It is determined whether or not the product has been scanned by the store clerk side scanner unit 212 or the like. That is, it is determined whether or not the store clerk has scanned with the store clerk side scanner unit 212, touched the store clerk side display unit 210, or pressed the key operation unit 211 or the like. If the product has been scanned, the process proceeds to step S401. If the product has not been scanned, the process proceeds to step S410.

Step S401: Register the product. In the registration, information indicating that the salesclerk has registered is also registered (stored). Specifically, the registration classification "1 (clerk side)" is stored (details will be described later).
Step S402: The product is displayed on the clerk's side display section 210 in a normal display mode.
Step S403: The product is displayed on the customer-side display section 205 in a display mode that emphasizes more than the normal display mode.

Step S410: It is determined whether or not the product has been scanned by the customer side scanner unit 206 or the like. That is, it is determined whether or not the customer has scanned with the customer-side scanner unit 206 or touched the customer-side display unit 205 . If the product has been scanned, the process proceeds to step S411. If the product has not been scanned, the process returns to step S400.

Step S411: Register the product. In the registration, information indicating that the customer has registered is also registered (stored). Specifically, the registration classification "2 (customer side)" is stored (details will be described later).
Step S412: The product is displayed on the clerk-side display section 210 in a display mode that is emphasized more than the normal display mode.
Step S413: The product is displayed on the customer-side display section 205 in a normal display mode.

Step S420: Determine whether or not registration of all products to be purchased has been completed. That is, it is determined whether or not either the subtotal key displayed on the salesclerk side display section 210 or the registration completion key displayed on the customer side display section 205 has been pressed. If all products have been registered, the process proceeds to step S421. If not completed, the process returns to step S400.

Step S421: Settle.
Step S422: The customer side printing unit 207 issues a receipt. The flowchart of FIG. 20 then ends. It should be noted that a printed receipt may be issued so that the merchandise registered by the store clerk and the merchandise registered by the customer can be distinguished from each other. For example, either one of the products registered by the store clerk or by the customer may be marked with a mark such as an asterisk or an asterisk, or underlined. Further, for example, a receipt may be issued in which the printing area for the product registered by the customer and the printing area for the product registered by the store clerk are separated. That is, a receipt may be issued in which the product registered by the customer and the product registered by the store clerk are printed in different areas.

FIG. 21 is an example of registration information. The POS terminal 20 may generate registration information as shown in FIG. 21, for example, instead of the registration information shown in FIG. The registration information shown in FIG. 21 stores a transaction number, transaction date and time, operation mode, product registrant, product code, product name, unit price, quantity, and specific product category. The operation mode is information indicating the current operation mode of the POS terminal 20 (when the registration information is generated). A product registrant is a registrant who has registered the product. The registration category is information indicating whether the registration was made by the store clerk or by the customer. When registered by the store clerk, the registration division "1" is stored, and when registered by the customer, the registration division "2" is stored.

As for the registration information shown in FIG. 21, in step S411 of FIG. 20 (registration processing based on scanning on the customer's side, etc.), the product code "SC1111" and "Japanese-style large-sized yakisoba A" are registered. In step S411, "star 4 (1 mm)" of product code "SC1023" is registered in (registration processing based on scanning by store clerk). .5L)” is registered, then in step S401, “Nori bento” with product code “SC6500” is registered, and in step S411, “C chocolate” with product code “SC3620” is registered. It is an example of generated registration information.

In other words, the POS terminal 20 generates registration information of the registration category "1 (clerk side)" in the process of step S401 for the product (star 4 (1 mm), seaweed lunch box) scanned by the clerk side scanner unit 212. . On the other hand, the POS terminal 20 registers the products scanned by the customer-side scanner unit 206 (large Japanese-style yakisoba A, natural water from mountain B (1.5 L), chocolate C) in the registration classification "2 ( Customer side)” registration information is generated.

FIG. 22 shows display examples on the store clerk side and the customer side. Specifically, FIG. 22A is an example of a registration screen displayed on the clerk-side display unit 210. As shown in FIG. FIG. 22B is an example of a registration screen displayed on the customer-side display section 205. As shown in FIG.

For example, when "C chocolate" is scanned by the customer-side scanner unit 206 in step S410 of FIG. 22(A) is displayed on the store clerk-side display unit 210, and in step S413, the customer-side display unit 205 displays a registration screen such as that shown in FIG. 22(B).

As shown in FIG. 22(A), on the store clerk side (clerk side display unit 210), the product (star 4 (1 mm), seaweed lunch box) registered by the clerk side (his own side) is displayed in a normal mode (normal size ), and the products registered by the customer (other party) (large Japanese-style yakisoba A, natural water from Mt. B (1.5 L), chocolate C) are displayed in an emphasized manner (enlarged size). In the upper part, the product (lunch box) last registered by the store clerk is displayed (symbol NI). In addition, at the bottom, the fact that it is the current mode (double scan mode) is notified (symbol M).

As shown in FIG. 22(B), on the customer side (customer side display unit 205), the products registered by the customer side (your side) (Japanese-style large portion of yakisoba A, natural water from Mt. B (1.5 L) , C chocolate) are displayed in a normal mode (normal size), and the products (star 4 (1 mm), seaweed lunch box) registered by the clerk side (opponent side) are displayed in an emphasized mode (enlarged size). In the upper part, the product (C chocolate) last registered on the customer side is displayed (symbol NI). In addition, at the bottom, the fact that it is the current mode (double scan mode) is notified (symbol M).

That is, based on the fact that the first product, "Japanese-style large serving of yakisoba A" has been scanned by the customer (step S410; YES), the clerk (clerk's side display unit 210) displays "Japanese-style large serving of yakisoba." A" is highlighted (step S412), and "Japanese-style large portion of yakisoba A" is normally displayed on the customer's side (customer-side display unit 205) (step S413). Subsequently, when the clerk side scans the second product, "Star 4 (1 mm)" (step S400; YES), the clerk side (clerk side display unit 210) displays "Star 4 (1 mm)". 4 (1 mm)" is normally displayed (step S402), and "star 4 (1 mm)" is highlighted on the customer side (customer side display section 205) (step S403). Subsequently, when the customer scans the third product, "Natural water from Mt. B (1.5 L)" (step S410; YES), the store clerk (store clerk's display unit ), “Natural water from Mt. B (1.5 L)” is highlighted (step S412), and “Natural water from Mt. B (1.5 L)” is normally displayed on the customer side (customer side display section 205). (step S413). Subsequently, based on the fact that the clerk has scanned the fourth product, "Lunch Box" (step S400; YES), the clerk side (clerk side display section 210) displays the "Lunch Box". It is normally displayed (step S402), and "Lunchbox" is highlighted on the customer's side (customer-side display unit 205) (step S403). Subsequently, when the customer scans the fifth product, "Chocolate C" (step S410; YES), the store clerk (display section 210 on the store clerk's side) displays "Chocolate C". It is highlighted (step S412), and "C chocolate" is normally displayed on the customer's side (customer-side display section 205) (step S413).

As shown in FIG. 22(A), on the clerk side, the products registered by the clerk side and the customer side (Japanese-style large serving yakisoba A, star 4 (1 mm), natural water from Mt. B (1.5 L), seaweed Boxed lunch, C chocolate) are displayed according to the registered order (Japanese-style large serving of yakisoba A -> Star 4 (1 mm) -> Natural water from Mt. B (1.5 L) -> Nori bento -> C chocolate). Therefore, even if we focus only on the products (star 4 (1 mm), seaweed lunch box) registered by the store clerk, the order in which the products (star 4 (1 mm), seaweed lunch box) were registered (star 4 (1 mm) → seaweed lunch box), and even if you focus only on the products registered by the customer (Japanese-style large serving yakisoba A, B mountain natural water (1.5 L), C chocolate), the product (Japanese-style Large serving yakisoba A, natural water (1.5 L) from mountain B, chocolate C) are displayed in the order in which they were registered (Japanese-style large yakisoba A→natural water from mountain B (1.5 L)→chocolate C). The same applies to the customer side (see FIG. 22(B)). The same applies to the display example of FIG. 23 (described later).

Also, as shown in FIGS. 22A and 22B, the product registered by the clerk (star 4 (1 mm), seaweed lunch) and the product registered by the customer (Japanese-style large serving yakisoba) Since the display mode is different from A and B mountain natural water (1.5 L), C chocolate), the overall registration order (Japanese-style large serving yakisoba A → Star 4 (1 mm) → B mountain natural water (1.5 L) → Nori Bento → C Chocolate), in addition to the registration order on the clerk side (Star 4 (1 mm) → Nori Bento) and the registration order on the customer side (Japanese-style large serving of yakisoba A → Natural water from Mt. B (1.5 L) → C Chocolate ) are also easier to recognize. The same applies to the display example of FIG. 23 (described later).

Note that in FIG. 22, the characters are enlarged and displayed for emphasis, but instead of or in addition to the enlarged characters, the characters may be displayed in bold.

(Other display example 1)
The displays on the clerk's side and the customer's side in the double scan mode are not limited to those described using the display example of FIG. FIG. 23 shows another display example on the store clerk side and the customer side. Specifically, FIG. 23A shows an example of a registration screen displayed on the clerk-side display unit 210. As shown in FIG. FIG. 23B is an example of a registration screen displayed on the customer-side display unit 205. As shown in FIG.

For example, when "C chocolate" is scanned by the customer-side scanner unit 206 in step S410 of FIG. 23A may be displayed on the salesclerk side display unit 210, and the registration screen as shown in FIG. 23B may be displayed on the customer side display unit 205 in step S413.

As shown in FIG. 23A, the store clerk side (clerk side display unit 210) displays the product (star 4 (1 mm), seaweed lunch box) registered by the store clerk side (own side) in a normal mode (normal size ), and the products registered by the customer (other party) (large Japanese-style yakisoba A, natural water from Mt. B (1.5 L), chocolate C) are emphasized (with a star, the first letter is moved forward) ). It should be noted that moving up by one character at the beginning means moving up the display start position by one character (moving or shifting to the left).

As shown in FIG. 23(B), on the customer side (customer side display unit 205), the products registered by the customer side (himself) (Japanese-style large portion of yakisoba A, natural water from Mt. B (1.5 L) , C chocolate) are displayed in a normal format (normal size), and the product (star 4 (1 mm), seaweed lunch box) registered by the clerk side (the other party) is displayed in an emphasized format (with a star, the first letter is moved ).

In FIG. 23, all three contents (character size, asterisk, character carry-over) are displayed as highlighting. good. Also, other marks (such as an asterisk) may be attached in place of the asterisks. As the highlighting, instead of or in addition to the above, highlighting with a background color or underlining may be performed.

In addition, in the flowchart of FIG. 20 and the display examples of FIGS. 22 and 23, an example has been described in which the product registered by oneself is displayed in a normal mode and the product registered by the other party is displayed in an emphasized mode. However, conversely, the products registered by the other party may be displayed in the normal mode, and the products registered by the user may be displayed in the emphasized mode.

In addition, on the store clerk side display unit 210, either the product registered by oneself or the product registered by the other party is not emphasized, but simply indicated by which side the product was registered. It may be displayed in an identifiable manner. For example, in the column of the product registered on your side, "Clerk" is displayed between the product name and the price, and in the column of the product registered on the other side, "" is displayed between the product name and the price. Customers” may be displayed. A badge-like image displaying "clerk" or a badge-like image displaying "customer" may be used.

Alternatively or in addition to the above, instead of emphasizing either the product registered by the user or the product registered by the other party on the customer side display unit 205, simply Which side is registered may be identifiably displayed. For example, "customer" is displayed between the product name and the price in the column of the product registered by the customer, and "customer" is displayed between the product name and the price in the column of the product registered by the other party. Salesperson" may be displayed.

(Other display example 2)
The displays on the clerk's side and the customer's side in the double scan mode are not limited to those described using the display examples of FIGS. 22 and 23 . FIG. 24 shows another display example on the store clerk side and the customer side. Specifically, FIG. 24A is an example of a registration screen displayed on the clerk-side display unit 210. FIG. FIG. 24B is an example of a registration screen displayed on the customer-side display unit 205. As shown in FIG.

When the customer-side scanner unit 206 scans the fifth product "C chocolate", the POS terminal 20 displays a registration screen as shown in FIG. A registration screen as shown in FIG.

FIG. 25 is a part of the flowchart in the modification. Specifically, FIG. 25A is obtained by replacing the processing of the rectangle P in the flowchart of FIG. That is, the POS terminal 20 executes step S1402 of the flowchart of FIG. 25A instead of step S402 of the flowchart of FIG. 20, and replaces step S403 of the flowchart of FIG. 25A is executed instead of step S412 of the flowchart of FIG. 20, and step S1413 of the flowchart of FIG. 25A is executed instead of step S413 of the flowchart of FIG. may be executed.

In other words, the POS terminal 20, for example, refers to the registration information (specifically, the registration category) shown in FIG. In step S1412 (FIG. 25A), a registration screen as shown in FIG. A registration screen as shown in (B) may be displayed.

As shown in FIG. 24A, in the first area H1 of the clerk side (clerk side display unit 210), the product (star 4 (1 mm), seaweed lunch box) registered by the clerk side (himself) is displayed. It is displayed in a normal mode (normal size), and in the second area H2 on the clerk side (clerk side display unit 210), the products (Japanese-style large serving yakisoba A, natural water from mountain B) registered by the customer side (opponent side) (1.5L), C Chocolate) is displayed in an emphasized manner (enlarged size). In addition, in order to show the display contents in the respective areas (first area H1, second area H2), the title "salesperson registered product" is displayed in the upper part of the first area H1, and The title "customer registration product" is displayed.

As shown in FIG. 24(B), in the first area H1 on the customer side (customer side display unit 205), the products registered by the customer side (your side) (Japanese-style large serving of yakisoba A, natural water from mountain B) (1.5 L), C chocolate) is displayed in a normal mode (normal size), and the product ( Star 4 (1 mm, seaweed lunch box) is displayed in an emphasized manner (enlarged size). In addition, in order to show the display contents in the respective areas (first area H1, second area H2), the title "products registered by the customer" is displayed in the upper part of the first area H1, and the upper part of the second area H2 is displayed. , the title "products registered by salesclerk" is displayed.

On the clerk side, as shown in FIG. 24A, the order in which the products (star 4 (1 mm), seaweed lunch box) registered by the clerk side in the first region H1 were registered (star 4 (1 mm)→ Nori lunch box), and the order in which the products registered by the customer in the second area H2 (Japanese-style large serving yakisoba A, natural water from Mt. B (1.5 L), C chocolate) were registered (Japanese-style large serving yakisoba A → Natural water from Mt. B (1.5 L) → Chocolate C). The same applies to the customer side (see FIG. 24(B)).

Note that FIG. 24 illustrates an example in which products registered by oneself are displayed in the first region H1 (left region) and products registered by the other party are displayed in the second region H2 (right region). However, on the contrary, it operates as shown in FIG. 25(B), displaying the products registered by itself in the second area H2 (right side area) and displaying the products registered by the other party in the first area H1. (Left side area).

Note that FIG. 25B is obtained by replacing the processing of the rectangle P in the flowchart of FIG. That is, the POS terminal 20 executes step S2402 of the flowchart of FIG. 25B instead of step S402 of the flowchart of FIG. 25B is executed instead of step S412 of the flowchart of FIG. 20, and step S2413 of the flowchart of FIG. 25B is executed instead of step S413 of the flowchart of FIG. may be executed.

FIG. 26 shows display examples on the store clerk side and the customer side. Specifically, FIG. 26A is an example of a small plan screen displayed on the clerk-side display unit 210 . FIG. 26B is an example of a small plan screen displayed on the customer-side display unit 205. As shown in FIG.

For example, the POS terminal 20 displays a registration screen as shown in FIG. After such a registration screen is displayed, if it is determined in step S420 that registration of all products to be purchased has been completed (step S420: YES), a checkout screen as shown in FIG. 26(B) is displayed on the customer side display unit 205. FIG. The customer confirms the total amount on the settlement screen of FIG. All products to be purchased are settled (step S421).

As shown in FIG. 26A, on the store clerk side (clerk side display unit 210), similar to the registration screen shown in FIG. , and the products registered by the customer side (the other party's side) are displayed in an emphasized manner. In addition, a button (symbol TG) for returning from the settlement screen to the registration screen is arranged at the bottom.

As shown in FIG. 26B, on the customer side (customer side display unit 205), the products registered by the customer side (self side) are displayed in the normal mode, similar to the registration screen shown in FIG. 22B. , and the products registered by the store clerk (other party) are displayed in an emphasized manner.

26A and 26B are subplan screens transitioned from the registration screens of FIGS. 22A and 22B, and subplan screens transitioned from the registration screens of FIGS. 23A and 23B. 24A and 24B are different from the microplan screens shown in FIGS. 26A and 26B. Specifically, the display mode of the product on the subplan screen transitioning from the registration screens of FIGS. 23A and 23B. The product display mode on the subplan screen transitioned from the registration screens of FIGS. 24A and 24B. The display mode of the product on the small plan screen to which the registration screen of (B) transitions may be the same as the display mode of the product on the registration screen of FIGS. 24A and 24B.

FIG. 27 is an example of a receipt. For example, in step S215 of FIG. 12 (the same applies to step S315 of FIG. 19), if both "star 4 (1 mm)" and "special frankfurter" are undelivered products, the POS terminal 20, for example, You may issue a receipt as shown in A). In the receipt shown in FIG. 27A, "star 4 (1 mm)" and "special frankfurter" are marked with an asterisk.

Also, the POS terminal 20, for example, in step S422 of FIG. 20, as shown in FIG. A receipt may be issued. Also, as shown in FIG. 27C, the POS terminal 20 may issue a receipt in which the product registered by the customer and the product registered by the store clerk are printed in different areas.

Although the embodiments and the like of the present invention have been described above, the device configuration, data configuration, processing flow, display and output mode, etc. can be changed and modified as appropriate.

(About operation mode)
The POS terminal 20 shifts to the full self mode when the POS terminal 20 continues to be unused (see FIG. 9A). Mode transition may be prohibited.

Also, by reading the clerk code, the mode shifts from the full self mode to the double scan mode (see FIG. 9B). Thus, the full self mode may be shifted to the double scan mode. When operating in the full-self mode, a screen on which buttons corresponding to each salesclerk are arranged may be displayed on the salesclerk-side display unit 210, and the salesclerk may be specified according to the button touched on the screen. . Also, by operating the key operation unit 211, the full self mode may be switched to the double scan mode. Note that buttons corresponding to each store clerk may be arranged on the key operation unit 211 and the store clerk may be specified according to the button operated on the key operation unit 211 .

Also, the POS terminal 20 operating in the normal mode, after transmitting a shift instruction to the other POS terminals 20, shifts to the semi-self mode (registration-only mode) after the processing if the POS terminal 20 itself is processing ( (See FIG. 10A), after transmitting the shift instruction, the mode may be forcibly (immediately) shifted to the semi-self mode (registration-only mode). For example, if a shift instruction is sent while the customer is executing payment processing on the customer side, the normal mode will immediately shift to semi-self mode (registration-only mode), while the payment processing that is in progress will be completed. , can be executed continuously.

Also, the POS terminal 20 operating in the normal mode or the like receives a transition instruction from another POS terminal 20, and if the POS terminal 20 itself is processing, it transitions to the semi-self mode (accounting mode) after the processing is completed. (See FIG. 10(B).) After receiving the shift instruction, the mode may be forcibly (immediately) shifted to the semi-self mode (accounting mode). For example, when a shift instruction is received while a salesclerk is executing registration processing at the salesclerk side, the normal mode is immediately shifted to the semi-self mode (accounting mode), while the registration processing being executed is completed. , can be executed continuously.

Also, the POS terminal 20 that operates in the full-self mode may function in a semi-self mode (accounting-only mode). That is, the POS terminal 20 operating in the semi-self mode (registration-only mode) transmits registration information to the POS terminal 20 operating in the semi-self mode (accounting-only mode), and operates in the semi-self mode (accounting-only mode). The POS terminal 20 is caused to execute the settlement process, and the POS terminal 20 operating in the semi-self mode (registration only mode) transmits registration information to the POS terminal 20 operating in the full self mode, and operates in the full self mode. The POS terminal 20 may be caused to execute the settlement process. Note that the POS terminal 20 operating in the semi-self mode (registration only mode) may transmit the registration information when the customer does not operate the POS terminal 20 operating in the full self mode. It may be possible to prevent the transmission of registration information while a customer is operating, or to transmit registration information so that payment can be made immediately after the customer's operation is completed even if the customer is operating. good too.

Further, in relation to transmission of registration information, a transmission button may be displayed on the clerk-side display section 210 of the POS terminal 20 that is the transmission source of the registration information. On the store clerk's side display unit 210, the transmission buttons for all other POS terminals on the LAN 11 are displayed so that each POS terminal can be identified (for example, with a terminal number such as "Register 1", "Register 2", etc.). display, etc.), or the send button of each POS terminal that can be the destination (POS terminal 20 operating in semi-self mode (accounting mode), POS terminal 20 in full self mode) can be identified. may be displayed in One or more POS terminals 20 to be permitted as destinations of registration information from the POS terminal 20 are determined in advance (that is, the coupling between the registration side and the settlement side is determined in advance), and based on this, the send button is pressed. may be displayed.

Also, the button corresponding to the POS terminal 20 that can currently transmit the registration information and the button corresponding to the POS terminal 20 that cannot transmit the registration information may be displayed in different display modes. For example, buttons corresponding to POS terminals 20 capable of transmitting registration information are displayed in a normal display manner, and buttons corresponding to POS terminals 20 incapable of transmitting registration information are displayed in a special display manner (for example, grayed-down). can be displayed with Buttons corresponding to POS terminals 20 that are currently incapable of transmitting registration information may be made inoperable or inhibited (for example, touch may be disabled).

In addition, the status of each POS terminal 20 to which registration information is to be sent (for example, waiting, in use, near-end, near-full, offline, etc.) may be reported. For example, the status of each POS terminal 20 is shared on the LAN 11 (for example, transmission and reception of information indicating the status, centralized management of the store controller 10 and one representative POS terminal 20, etc.), and on the above button ( or associated with a button) to display information indicating the status of each POS terminal 20 (for example, a badge-like image displaying "waiting", "in use", "near end", etc.). In the case of the POS terminal 20 operating in the full self mode, it is on standby when the customer does not operate it, changes from standby to in use when the customer starts registration, and goes from in use to standby again when payment is completed. get inside. During use may be divided into during registration and during payment before and after the operation of the registration completion key (subtotal key).

Also, when the customer is using the POS terminal 20 operating in the full self mode, the transition to the normal mode may be restricted. For example, when a customer is processing payment in full self mode, transition to normal mode is permitted, and when a customer is registering in full self mode, transition to normal mode is prohibited (at least immediate transition prohibited).

Further, although the POS terminal 20 has been described as shifting the operation mode according to the explicit mode shifting operation by the store clerk, even with the explicit mode shifting operation, the operation mode before transition (current operation mode), the transition destination The operation may be restricted depending on the operation mode, operation status, and the like.

The operation mode of the POS terminal 20 may be scheduled according to the work status of the clerk (attendance status, work schedule, work schedule). However, depending on the operation mode before transition (current operation mode), the operation mode after transition, the operation status, etc., there may be cases where control is performed as scheduled and cases where control is not performed as scheduled.

As the notification of the operation mode, the POS terminal 20 displays the operation mode on the display unit (clerk-side display unit 210, customer-side display unit 205), but the manner of notification of the operation mode is not limited to this. For example, the POS terminal 20 has a patrol light (registered trademark), a display board, or the like (or the patrol light, the display board, etc. is connected to the POS terminal 20), and the operation mode of the POS terminal 20 is notified by the patrol light, the display board, or the like. You may Also, the POS system 1 may be equipped with a patrol light, a display board, etc. (or the patrol light, the display board, etc. may be connected to the LAN 11), and the operation mode of each POS terminal 20 in the store may be notified by the patrol light, the display board, etc. . By using a patrol light, a display board, or the like, the operation mode can be visually recognized even from a distance (a position away from the clerk-side display unit 210).

(Regarding sales of specific products)
As a method for the customer to specify the specific product to be purchased, an example of selecting from the screen has been described (FIG. 11), but the method for the customer to specify the specific product to be purchased is not limited to this. For example, prepare an order sheet (or order book) printed with a barcode, etc., associated with a specific product (photo, illustration, etc.), and send the barcode printed on the order sheet (order book) to the customer. You can scan.

It has been explained that the notification that there are undelivered products or that an exchange ticket has been issued is to send information to a terminal carried by the store clerk. may Also, the notification mode is not limited to transmission and reception of information. For example, voice (in-store announcement, buzzer, chime, melody, etc.) and light (backyard or office room light, lamp, etc.) may be used.

Further, the notification mode may be changed according to the stage (number of times of notification). For example, the notification by the same means may be gradually strengthened (for example, the volume of the call chime may be gradually increased, or the chime output interval may be gradually shortened). Also, the notification means may be changed. The first stage is guidance in the store (for example, a call saying "Customers are waiting"), and the second stage is blinking the room lights in the backyard and office. In the third stage, an in-store announcement may be made to name the name of the person responsible for the time slot.

When there are a plurality of store clerks in the store, at least one person may be notified, or all of them may be notified. The information about the clerk to whom the notification is sent may be stored in the storage unit (RAM 203, hard disk 204, etc.). Alternatively, the notification may be made in order according to a predetermined order (priority order). Information about the order (order) may also be stored in the storage unit.

Regarding age authentication when delivering a specific product, for example, a voucher for a specific product that requires age authentication (see FIG. 16A) or a voucher that includes a specific product that requires age authentication (see FIG. 16C) When the barcode of is read, an authentication screen with an age authentication button etc. is displayed on the customer side display unit 205 of the POS terminal 20 (or the display unit of another terminal connected to the LAN 11), The customer may be asked to touch the button. The POS terminal 20 stores the age authentication category as registration information when registering the product, and refers to the registration information (or the registration information and the product master) when reading the bar code of the exchange ticket. If it is determined that the specific product of the exchange ticket (the specific product to be handed over) requires age verification and age verification has not yet been performed, the authentication screen described above may be displayed.

In the case of specific products that require age authentication (alcoholic beverages, cigarettes, etc.), media such as a driver's license, taspo card, or My Number card may be made recognizable, thereby saving the intervention of a store clerk. For example, if age authentication without the intervention of a store clerk is accepted as an operation through these media, the scene of issuing a voucher will decrease (for example, if age authentication performed with a driver's license, etc. during the registration process is accepted , because it is not necessary to issue exchange tickets for alcoholic beverages), which is convenient for both the store clerk and the customer.

If there is no stock for the specific product (specific product to be delivered) of the exchange ticket, return processing is performed. When specifying (purchasing) a specific product (for example, see FIG. 11), it may be arranged such that a specific product that is out of stock cannot be specified.

In the above flowchart (see FIGS. 12 and 19), the exchange ticket is issued after the receipt is issued. A receipt may be issued. For example, in the case of the flowchart of FIG. 12, it is determined whether there are undelivered products without issuing a receipt after payment, and if there are undelivered products, a receipt is issued after at least issuing an exchange ticket, If there are no undelivered goods, only a receipt may be issued.

If the customer can be identified prior to issuance of the voucher, information about the customer may be printed on the voucher. For example, if the customer's membership card is read before the exchange ticket is issued, the customer's (member's) membership number or information acquired based on the membership number (for example, name, "Mr. XX", etc.) and You may print. Also, in each receipt shown in FIG. 27, information related to the customer may be similarly printed.

Also, the exchange ticket may be electronic information instead of a paper medium. For example, an exchange screen corresponding to the exchange ticket (for example, a screen displaying code information) may be transmitted to the terminal carried by the customer. The transmission/reception method may be, for example, RFID, Bluetooth (registered trademark), wireless LAN, e-mail, short mail, or SNS.

In the above description, the POS terminal 20 displays information on undelivered products (see FIG. 15) and information on exchange tickets (see FIG. 17). A personal computer installed in the backyard, an information display device, etc.) may display information on undelivered products and information on vouchers. It should be noted that another device may access necessary information (for example, specific product delivery management information shown in FIG. 14, etc.) and generate and display information on undelivered products and information on vouchers by itself. , the POS terminal 20 may generate information on undelivered products and information on vouchers and transmit (supply) them to other devices. Further, by sharing (for example, storing in the store controller 10, etc.) various types of information (such as the information shown in FIG. 14, etc.), other POS terminals 20 can read exchange tickets issued by one POS terminal 20. may

It should be noted that the information from the issuance of the exchange ticket to the delivery of the product may be utilized for management and operation (product revision and abolishment, staff placement, etc.). Specifically, in the specific product delivery management information (see FIG. 14), the issuance status of exchange tickets for each time slot and store may be analyzed based on the issuance classification, or based on the ticket issue time and exchange time Then, the required time after ticket issuance may be evaluated for each time zone or each store. An electronic journal, which will be described later, may also be used.

(Display etc. in double scan mode)
In the above flowchart (see FIG. 20), when either the subtotal key displayed on the clerk-side display unit 210 or the registration completion key displayed on the customer-side display unit 205 is pressed (step S420: YES) , displaying the sub-plan screen (see FIG. 26). In other words, product registration is completed by either the store clerk side (subtotal key) or the customer side (registration completion key). However, the mode of completing the product registration (the operation of displaying the small plan screen) is not limited to this.

For example, the subtotal screen may be displayed only when the clerk's subtotal key is pressed. In other words, the customer may not perform the operation to complete the product registration, and only the store clerk may perform the operation to complete the product registration. In this mode, the customer-side display unit 205 may display the registration completion key in a display mode indicating that the operation is not valid (for example, grayed-down), or may not display the registration completion key.

Further, the subtotal screen may be displayed when both the clerk's subtotal key and the customer's registration completion key are pressed. That is, when the subtotal key is pressed by the store clerk first (when the subtotal key is in a state of being pressed), the subtotal screen is displayed at the timing when the registration completion key is pressed by the customer. When the customer first presses the registration completion key (when the registration completion key is pressed), the subtotal screen is displayed at the timing when the clerk presses the subtotal key. may

In the aspect of displaying the subtotal screen when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, when either the subtotal key or the registration completion key is pressed, the fact that the subtotal key or the registration completion key is pressed is displayed. may be notified to the other party. For example, when the subtotal key is pressed first, a message to the effect that the subtotal key has been pressed (that is, to indicate that the store clerk has performed the product registration operation. For example, a message such as "The store clerk has completed product registration") ) may be displayed on the customer-side display unit 205 . On the other hand, if the registration completion key is pressed first, the message indicating that the registration completion key has been pressed (that is, the customer has performed the product registration operation. For example, "the customer has finished registering the product") message, etc.) may be displayed on the clerk-side display unit 210 .

When the subtotal key is pressed, instead of or in addition to displaying on the customer side display section 205 that the subtotal key has been pressed, the registration completion key displayed on the customer side display section 205 is displayed. The display mode may be displayed in an emphasized mode (blinking or the like) until the registration completion key is pressed. Similarly, when the registration completion key is pressed, instead of or in addition to displaying the fact that the registration completion key has been pressed on the store clerk side display unit 210, The key display mode may be displayed in an emphasized mode (blinking or the like) until the subtotal key is pressed.

In the mode in which the subtotal screen is displayed when both the subtotal key on the clerk side and the registration completion key on the customer side are pressed, pressing of the registration completion key is prohibited (for example, grayed-down, non-display) until the subtotal key is pressed. etc.), and after the subtotal key is pressed, the registration completion key may be permitted to be pressed (for example, displayed in a display mode that can be pressed). Alternatively, pressing of the subtotal key may be prohibited until the registration completion key is pressed, and pressing of the subtotal key may be permitted after the registration completion key is pressed.

In a mode in which a subtotal screen is displayed when both a clerk's subtotal key and a customer's registration completion key are depressed, even after the clerk's subtotal key is depressed, the customer's registration completion key is not depressed. In some cases, the registration may be temporarily completed on the store clerk's side, and registration of the product may be permitted. That is, when the clerk presses the subtotal key, the other party (customer side) is informed that the subtotal key has been pressed, but the subtotal screen is displayed even after the subtotal key has been pressed. During this period (before the customer presses the registration completion key), the store clerk may be able to register (additionally register) the product that has not yet been registered by the customer.

In addition, if the product is additionally registered after the store clerk completes the product registration (when the product is additionally registered in the state of temporary completion of registration), in order to display the small plan screen, An operation (pressing down of the subtotal key) is required to complete product registration again on the store clerk side. In other words, after the product is additionally registered, the sub-plan screen is displayed when both the sales clerk presses the subtotal key again and the customer presses the registration completion key. Note that, instead of the above, an operation to complete product registration again on the store clerk side may be unnecessary. That is, after the product is additionally registered, the sub-plan screen may be displayed if the customer presses the registration completion key even if the sales clerk does not press the subtotal key again.

Note that after the subtotal key is pressed and before the registration completion key is pressed, the store clerk may be allowed to additionally register the product of the customer as described above. As in the example above, it may be possible to allow the next customer to register the product. Note that after pressing the subtotal key and before pressing the registration completion key, the clerk side display unit 210 declares whether to additionally register the product of the customer or to register the product of the next customer ( specified). For example, a button displayed on the clerk-side display unit 210 may be used to declare.

In the double scan mode, when the same product is scanned by both the customer side and the store clerk side, the fact that the same product has been scanned by both the customer side and the store clerk side may be notified. For example, the display unit may display a message such as "the same product has been scanned" or "this is the XXth scan". Note that the display destination of the message may be at least the store clerk. In other words, when the same product is scanned by both the customer side and the store clerk side, the message is always displayed on the store clerk side display section 210, but the customer side display section 205 may or may not display the message. may For example, when the store clerk scans the same product that has already been scanned by the customer, a message is displayed on the store clerk display unit 210, and the same product as the product already scanned by the clerk is displayed on the customer side. When the document is scanned by the customer side display section 205 and the store clerk side display section 210, a message may be displayed. Further, for example, whether or not to display the above-described message on the customer-side display unit 205 may be controlled according to the setting operation (or switching operation) by the store clerk.

In the above description, during product registration (registration screen) and after product registration (small plan screen), the store clerk side display unit 210 displays the product registered by the customer (customer side) and the product registered by the customer (customer side). 22(A), 23(A), 24(A), and 26(A)), and the customer's side display unit 205 registers the customer's side (customer's side). 22(B), 23(B), 24(B), and 26(B). ), and the display mode on the store clerk side display section 210 and the customer side display section 205 is not limited to this.

For example, the clerk-side display unit 210 does not display the products registered by the other party (customer), but displays the products registered by the customer (clerk). ), instead of displaying the products registered on the customer side, the products registered on the customer side may be displayed. Alternatively, as shown in FIG. 22(A), the clerk-side display unit 210 displays the products registered by oneself (clerk side) and the products registered by the other party (customer side) in different display modes. Alternatively, the customer-side display unit 205 may display products registered by oneself (customer side) instead of displaying products registered by the other party (clerk side). Alternatively, the clerk-side display section 210 does not display the commodities registered by the other party (customer side), but displays the commodities registered by the user (clerk side), and the customer-side display section 205 displays FIG. 22(B). etc., the products registered by the user (customer side) and the products registered by the other party (clerk side) may be displayed in different display modes.

Even if the clerk-side display unit 210 is allowed to declare (specify) whether or not to display (or not display) the product registered by the other party (customer) on its own side (the store clerk-side display unit 210). good. In place of or in addition to the above, the clerk-side display unit 210 declares whether or not to display (or not to display) the product registered by oneself (the clerk) on the other side (customer-side display unit 205). specified). In place of or in addition to the above, the customer-side display unit 205 declares whether or not to display the product registered by the other party (clerk side) on its own side (the customer-side display unit 205) (or not). (specified) may be enabled. Either of these may be declared by a button or the like displayed on the screen.

During product registration, for example, as shown in FIG. 24, the product registered by oneself and the product registered by the other party are displayed in different display areas. As shown in , the product registered by the user and the product registered by the other party may be displayed in a common display area. In other words, for example, when the subtotal key or the like is pressed to transition from the registration screen to the subtotal screen, the products registered on one's side and the products registered on the other side displayed in different display areas on the registration screen before pressing the subtotal key, etc. The selected products may be displayed in a common display area on the sub-plan screen after the subtotal key or the like is pressed. Also, when the registration screen button (symbol TG in FIG. 26A) is pressed to transition from the subplan screen to the registration screen, the subplan screen displayed in the common display area before pressing the registration screen button The registered product and the product registered on the other side may be displayed in different display areas on the registration screen after the registration screen button is pressed.

In the salesclerk-side display unit 210, regarding the display mode during and after product registration on the salesclerk-side display unit 210 and the customer-side display unit 205, the product registered on the self side and the product registered on the other side are displayed. It may be made possible to declare (specify) whether the products and the products that have been purchased are to be displayed in different display areas or displayed in a common display area. In place of or in addition to the above, in the customer-side display unit 205, regarding the display mode during product registration and after product registration on the customer-side display unit 205, It may be possible to declare (specify) whether the registered product is to be displayed in a different display area or in a common display area. Either of these may be declared by a button or the like displayed on the screen.

(About the printing department)
In the above description, the POS terminal 20 includes printing units (clerk-side printing unit 213 and customer-side printing unit 207) on the clerk side and the customer side (see FIGS. 2 to 4). may be one (that is, one may be shared). For example, it is possible to provide a single printing unit that can be rotatably changed from the clerk side to the customer side and from the customer side to the clerk side (the direction of the medium issue port). The orientation of the printing unit may be changed manually, or automatically according to the transition of the operation mode (here, normal mode, full self mode, double scan mode, semi self mode, total mode, etc.). may be mechanically changed (mechanically controlled, etc.). Further, correctness or incorrectness of the orientation of the printing unit may be detected by a sensor or the like.

(About analysis, etc.)
The POS system 1 may store electronic journals and utilize them for various analyses. Even if the electronic journal contains various information shown in FIGS. 13, 14, 21, etc., and the output information shown in FIGS. good. For example, the POS terminal 20 (or the store controller 10) stores an electronic journal for each transaction, and the operation status of each operation mode (for example, by time zone and day of the week, by person in charge, or unconditionally, for each mode) operating hours, etc.), sales performance of specific products (e.g. number of sales, etc.), operational status of exchange tickets (e.g. number of exchange tickets issued, ratio of exchange tickets issued to number of sales of specific products, issuance of exchange tickets) the time required until the product is delivered later, etc.), and the registration status of the store clerk and the customer in double scan mode (the ratio of the number of product registrations between the store clerk and the customer, etc.). If it is possible to grasp the attributes (gender age) of each customer, it may be analyzed by customer). The analysis results may be output as a list or the like.

In addition, by storing in the electronic journal, for example, the registration start time (in seconds) of the first product in each transaction and the display start time of the small plan screen, etc. ) (for example, the time required to complete the registration process (to start displaying the subplan screen)) may be analyzed.

(Other conditions for issuing media)
In the above description, the medium (exchange ticket) is issued due to the registration or provisional registration of a specific product (although there are other conditions such as completion of registration of all products) (for example, FIG. 12, FIG. 19). ), the media may be published on other terms. For example, during the implementation period of a campaign to provide a card (a card that can be exchanged for a specific product according to the printed content) to a customer whose total amount exceeds a predetermined amount, it is possible that the total amount exceeds the predetermined amount. As a result (although there are other conditions such as completion of registration of all products), a medium (exchange ticket) that can be exchanged for the card may be issued.

(About other displays)
In the above description, the information about the exchange ticket is displayed (see, for example, the exchange ticket notification area HJ in FIG. 17). Other information may be displayed. For example, information related to registration (or provisional registration) of a specific product, information related to errors (for example, warning about change, warning about paper, information about calling a clerk, etc.) may be displayed. Further, by transmitting and receiving information via the LAN 11, information on other POS terminals 20 may be displayed instead of or in addition to information on the POS terminal 20 concerned. When displaying information related to another POS terminal 20, the display may be performed according to the position of the other POS terminal 20 (the positional relationship with the POS terminal 20 concerned).

Each POS terminal 20 refers to information indicating the positional relationship with other POS terminals 20 (for example, each POS terminal 20 itself may store and refer to the information indicating the positional relationship, The store controller 10 may store the information indicating the positional relationship, and each POS terminal 20 may access the store controller 10 and refer to the information indicating the positional relationship. may be displayed. Alternatively, the display position may be determined in advance for each other POS terminal 20 .

For example, the left and right display positions may differ depending on the arrangement of the POS terminal 20 . As an example, the POS terminal 20-1 is arranged on the left side of the POS terminal 20-2 (the left side as viewed from the store clerk), and the POS terminal 20-3 is arranged on the right side of the POS terminal 20-2 (the right side as viewed from the store clerk). (that is, when viewed from the clerk-side display unit 210, the POS terminal 20-1 is arranged on the left, the POS terminal 20-2 is arranged in the center of the left and right, and the POS terminal 20-3 is arranged on the right. 20-2), information on the POS terminal 20-1 located on the left side of the POS terminal 20-2 is displayed on the left side of the screen on the clerk side display section 210 of the POS terminal 20-2 placed in the center of the left and right sides. POS terminal 20-3 located on the right side of the POS terminal 20-2 may be displayed on the right side of the screen (see FIG. 28).

In addition, in the clerk side display section 210 of the POS terminal 20-1 arranged on the left side, information on the POS terminal 20-2 and the POS terminal 20-3 located on the right side of the POS terminal 20-1 is displayed on the right side of the screen. may be displayed. For example, even if information about the POS terminal 20-3 located farther from the POS terminal 20-1 is displayed to the right than information about the POS terminal 20-2 located closer to the POS terminal 20-1, Good (see Figure 29). Similarly, on the clerk side display unit 210 of the POS terminal 20-3 arranged on the right side, information on the POS terminal 20-1 and the POS terminal 20-2 located on the left side of the POS terminal 20-3 is displayed on the left side of the screen. may be displayed in For example, even if information about the POS terminal 20-1 located farther from the POS terminal 20-3 is displayed on the left side than information about the POS terminal 20-2 located closer to the POS terminal 20-1. Good (not shown).

FIG. 28 shows an example of display on the clerk's side display section 210 of the central POS terminal 20 (the POS terminal 20-2 in the above description) of the three POS terminals 20 arranged side by side in the store. FIG. 29 shows an example of display on the clerk's side display section 210 of the left POS terminal 20 (POS terminal 20-1 in the above description) among the three POS terminals 20 arranged side by side in the store.

In FIG. 28, an area HJa on the left side of the screen is a display area for displaying information regarding the POS terminal 20 (the POS terminal 20-1 in the above description) on the left side. In the area HJa, in addition to information on exchange tickets, information on registration (or provisional registration) of specific products (specifically, the fact that one special frankfurter was purchased) and information on errors (specifically, near-end ) is also displayed. The area HJb on the right side of the screen is a display area for displaying information about the POS terminal 20 on the right side (the POS terminal 20-3 in the above description). In the area HJb, in addition to the information about the exchange ticket, it is also displayed that two Star 4 (1 mm), which is a specific product, has been purchased (ordered).

In FIG. 29, an area HJc on the right side of the screen is a display area for displaying information about the central POS terminal 20 (the POS terminal 20-2 in the above description). The area HJd on the right side of the screen is a display area for displaying information about the POS terminal 20 on the right side (the POS terminal 20-3 in the above description). In the area HJd, in addition to the information on the exchange ticket, information on the registration (or provisional registration) of the specific product (specifically, the fact that two 4-star (1 mm) were purchased) is displayed.

In the display of the exchange ticket, information about the elapsed time from the issuance of the exchange ticket (for example, "2 minutes passed", etc.) is displayed. Information about elapsed time since registration) may be displayed. Also, in the error display, etc., information regarding the elapsed time from the occurrence of the error or the like may be displayed.

In addition, in the above-described areas (area HJa, etc.), the display mode may be changed according to the type of display information (for example, exchange ticket, specific product, error, etc.). In the area HJa of FIG. 28, the corners are rounded so as to distinguish errors (specifically, near-end) from others. Also, the priority (for example, display order, etc.) may be changed based on the type of display information. For example, in FIG. 28, information related to errors and the like is displayed below other information, but it may be displayed above other information.

It should be noted that the above-described areas (area HJa, etc., including area HJ in FIG. 17) may always be displayed regardless of whether there is display information or not, or may be displayed when there is display information or not. In some cases, it may not be displayed. For example, when there is no display information in the area HJb in FIG. Although the display information in the area HJb disappears, the area HJb itself may remain displayed without being erased, or the area HJb itself may be erased (even if other parts such as preset keys are moved to the right). good). That is, the area may be always secured regardless of the presence or absence of display information, or may be secured according to the presence or absence of display information.

Also, the examples shown in FIGS. 28 and 29 are display examples when three POS terminals 20 are arranged in the store, but the same may be applied when there are two or four or more POS terminals. For example, four POS terminals 20 are arranged in the store, and the above-described area is displayed in a maximum of three columns on the right side of the clerk-side display section 210 of the leftmost POS terminal 20 (three columns may always be displayed).

In the above description, the current operation mode of the own POS terminal 20 is displayed (for example, symbol M in FIG. 17). , the current operation modes of other POS terminals 20 may also be displayed.
