FIG. 3B is a perspective view of the POS terminal 20 as seen from the salesclerk side. FIG. 4 is a diagram showing a configuration example of the POS terminal 20. As shown in FIG. 3 and 4, the same reference numerals are given to the same parts.

An example configuration of the POS terminal 20 shown in FIG. 4 will be described below with reference to FIGS. 2 and 3. FIG. The POS terminal 20 includes a CPU 201, a ROM 202, a RAM 203, a hard disk 204, a customer-side display unit 205, a customer-side scanner unit 206, a card reader 208, a change machine 209, a salesclerk-side display unit 210, a key It includes an operation unit 211 , a store clerk-side scanner unit 212 , a printing unit 213 , an audio output unit 214 , a communication unit 215 , an imaging unit 216 , and a sign pole 217 . They can communicate with each other via a bus.

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

A RAM 203 is a read/write memory and stores various information. For example, the RAM 203 stores information acquired from the outside (for example, product master information acquired from the store controller 10) and information generated during processing (for example, registration information generated during registration processing, settlement information generated during settlement processing, etc.). memorize

The hard disk 204 stores various information. The hard disk 204 may store programs executed by the CPU 201 instead of the ROM 202, for example. Also, instead of the RAM 203, information obtained from the outside or information generated during processing may be stored.
A storage device such as an SSD (Solid State Drive) may be provided instead of the hard disk 204 .

The customer-side display unit 205 is a touch display for customers, which displays various information to the customer and receives various inputs from the customer.
A customer-side scanner unit 206 is a scanner unit for customers, and optically reads, for example, a bar code (such as a product code) attached to a product.

The customer-side scanner unit 206 is used when the customer registers the product, but the customer may register the product by another method. For example, when an item order button or the like is displayed on the customer-side display unit 205, the customer can operate (press) the order button to register the item.

The card reader 208 can read information from various cards (credit cards, transportation cards, etc.) and execute processing corresponding to settlement. Also, the card reader 208 can read information such as membership cards and point cards. The card reader 208 of this embodiment may include, for example, a card recognition unit (reading unit), a display unit, and an operation unit, and may include at least a card recognition unit.

The change dispenser 209 (cash settlement unit) is a settlement mechanism using cash, and has an insertion port for banknotes and coins and a discharge port for banknotes and coins. The amount of change, which is the difference, is calculated, and the change is discharged from the discharge port.

The clerk-side display unit 210 is a touch display for the clerk, and displays various information to the clerk and receives various inputs from the clerk.
The key operation unit 211 is composed of various keys (buttons) and receives various inputs from the store clerk.
The clerk-side scanner unit 212 is a scanner unit for a clerk, and optically reads, for example, a bar code (product code, etc.) attached to a product or a clerk code attached to a clerk's name tag.

Note that the clerk-side scanner unit 212 is used when the clerk registers products, but the clerk may register the products by other methods. For example, if a key corresponding to a product (for example, a key corresponding to a sports newspaper) is arranged in the key operation unit 211, the store clerk can operate (press) the key to register the product. can. Also, when a preset key corresponding to a product is displayed on the clerk-side display unit 210, the clerk can operate the preset key to register the product.

The printing unit 213 is a printing unit that ejects media, and prints and issues various media such as receipts. The printing unit 213 is 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 issuing port). The orientation of the printing unit 213 may be changed manually, or may be changed automatically (mechanically controlled, etc.) according to the transition of the operation mode, for example. Note that whether the orientation of the printing unit 213 is correct or incorrect may be detected by a sensor or the like.

The audio output unit 214 outputs audio. For example, the audio output unit 214 outputs audio guidance and the like.
The communication unit 215 transmits and receives information to and from other devices (other POS terminals 20, store controllers 10).

The imaging unit 216 is provided so as to capture an image of a customer performing an operation related to checkout at the customer's standing position. A captured image obtained by capturing an image by the imaging unit 216 can be used as a monitoring image for monitoring a customer who pays the bill. In addition, the POS terminal 20 can store the image captured by the imaging unit 216 in a storage device such as the hard disk 204 or the like.

The imaged image obtained by imaging by the imaging unit 216 is used, for example, to verify the amount actually deposited or as evidence. For example, if a customer claims to have deposited a 10,000-yen bill, but the automatic change-change machine records that the customer has deposited a 1,000-yen bill, the photographed image will indicate that the automatic change-change machine has not misrecognised. It is possible to verify that the customer has actually deposited the 1,000-yen bill, and the captured image can be used as objective evidence.

Note that the imaging information captured by the imaging unit 216 may always be displayed on the customer-side display unit 205 of the POS terminal 20 in real time. By constantly displaying the captured image, the customer using the POS terminal 20 is aware that the captured image is being captured, so there is an effect of deterring fraud.

A second customer-side display unit having a display area larger than that of the customer-side display unit 205 may be newly provided as a display unit for displaying the captured image, and this second customer-side display unit may be used. Since the second customer-side display unit has a large display area, it has the effect of further deterring fraud. Further, the mounting position of the second customer-side display unit may be either on the top or on the left or right of the customer-side display unit 205 . In particular, if it is installed at a position (for example, upper part) where the visibility from a distance is improved, the store clerk (especially the monitor) can monitor the customer's usage status etc. from a remote position.

The imaging unit 216 stores captured images obtained by recording in the hard disk 204, for example. The recording period is, for example, the period from the start of the transaction until the customer takes the receipt and leaves the POS terminal 20 . If the POS terminal 20 is provided with means (for example, a human sensor) that can determine whether or not there is a customer in front of the POS terminal 20, the period in which the customer is in front of the POS terminal 20 may be recorded.

Also, regardless of whether there is a transaction or whether there is a customer in front of the POS terminal 20, the video may be constantly recorded. In the case of constant recording, a function may be provided for deleting portions determined to be unnecessary after recording. As an example of the processing of this function, there is processing for saving data from five seconds before pressing a button 301 (registration start button) shown in FIG. As a result, the state before the button 301 is pressed can be reliably left as a captured image.

The sign pole 217 is a part that lights up in a predetermined pattern and color to give a predetermined notification to the store clerk.

[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 related to accounting during normal business (operation modes related to product registration processing and settlement processing). It does not include the maintenance mode for setting work or maintenance work by staff members, or the training mode for training newcomers.
In this embodiment, "accounting" is a concept that includes, for example, product registration in one transaction and settlement (settlement) of the registered product.
In the following description, the mode in which the POS terminal 20 executes product registration processing is referred to as a registration mode, and the mode in which payment processing is performed is referred to as a payment mode, as a different approach from the four operation modes described above. There is

[Normal mode]
The normal mode is an operation mode in which the store clerk executes the registration process and the customer executes the settlement process. That is, in the case of the normal mode, the store clerk side becomes the registration mode, and the customer side becomes the checkout mode. In other words, the POS terminal 20 operates in the registration/settlement mode when viewed 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 registration processing of the purchased product by the operation of the store clerk (operation of the store clerk side scanner unit 212, store clerk side display unit 210, key operation unit 211, etc.).

When the store clerk completes the registration process, the customer confirms the total amount of purchased commodities on the store clerk side display unit 210 and inserts money into the change machine 209 or operates the card reader 208 to settle the bill. In other words, the POS terminal 20 executes settlement processing according to a customer's operation (insertion of money into the change machine 209, operation of the card reader 208).

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. In other words, the POS terminal 20 can accept payment during the registration process.

In addition, the clerk may wait until the customer completes the payment (until the customer obtains the change or the receipt), or may register the next customer's purchased product. In other words, the POS terminal 20 can register the next customer's purchased product during the checkout process. Also, the clerk may be absent while the customer is checking out. 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. , the printing unit 213 is controlled to issue a receipt. 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 store 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]
The full-self mode is an operation mode in which the customer executes registration processing and the customer executes settlement processing. That is, in the case of the full self mode, the customer side becomes both the registration mode and the payment mode. In other words, the POS terminal 20 operates in the registration/settlement mode when viewed 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). In other words, 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).

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 reader 208 in the case of credit card payment, and settles the account. do. In other words, the POS terminal 20 executes settlement processing according to a customer's operation (insertion of money into the change machine 209, operation of the card reader 208).

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. In addition, the POS terminal 20 can display various information on the clerk-side display section 210 even when operating in the full self mode.
For example, during operation in the full-self mode, a screen similar to that displayed on the customer-side display unit 205 can be displayed on the salesclerk-side display unit 210 in accordance with the registration processing and settlement processing performed on the customer side. may be displayed. In other words, the contents displayed on the customer-side display unit 205 may be mirrored on the salesclerk-side display unit 210 . This allows the clerk to grasp what kind of operation the customer is performing and what kind of processing status the POS terminal 20 is in in the full-self mode.

[Double scan mode]
The double scan mode 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, 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/settlement mode when viewed 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), registration processing of the purchased product is executed.

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 reader 208 in the case of credit card payment, and settles the account. do. In other words, the POS terminal 20 executes settlement processing according to a customer's operation (insertion of money into the change machine 209, operation of the card reader 208).

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 next customer's purchased product during the checkout process. Also, the clerk may be absent while the customer is checking out. 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 in which two or more POS terminals 20 are used, in which registration processing is executed by the clerk of at least one POS terminal 20, and payment is made by the customer of the other POS terminal 20. This is the operation mode for executing processing. That is, in the semi-self mode, one or more POS terminals 20 are in the registration-only mode, and one or more other POS terminals 20 are in the payment-only 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 registration processing of the purchased product by the operation of the store clerk (operation of the store clerk side scanner unit 212, store clerk side display unit 210, key operation unit 211, etc.).

When the registration process by the clerk is completed, the customer moves to the POS terminal 20 in the settlement-only mode, confirms the total amount of purchased commodities on the clerk-side display unit 210, inserts money into the change machine 209, or presses the card reader. 208 and settle the account. In other words, the POS terminal 20 executes settlement processing according to a customer's operation (insertion of money into the change machine 209, operation of the card reader 208).

When the registration process is completed at the POS terminal 20 in the registration-only mode, the customer moves from the POS terminal 20 in the registration-only mode to the POS terminal 20 in the settlement-only mode. Necessary information (such as registration information generated by the POS terminal 20 in registration-only mode) is supplied.

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

In the semi-self mode, after sending the registration information, the store clerk can register the next customer's purchased product. Also, the store clerk may be absent after sending the registration information.

Transaction information control processing will be described based on the above configuration. The transaction information control process is a process executed during operation in the full-self mode, and is a process related to deletion of transaction information. The transaction information here is information generated from the start of the transaction to the completion of the transaction in the full-self mode. Examples of transaction information include transaction number, cash register number, person in charge number, member information, product information, payment type information, presence/absence of bag, and the like.

Here, the transaction number is a number uniquely assigned to each transaction to identify the transaction. A register number is a unique number assigned to each POS terminal 20 to identify the POS terminal 20 . A person-in-charge number is a number uniquely assigned to each POS terminal 20 in order to identify a salesclerk in charge of the POS terminal 20 . Since the POS terminal 20 is in the full-self mode, the clerk does not operate the POS terminal 20 for transactions. The member information is customer-related information (for example, member number, points, etc.) provided for each customer. Product information is information (product name, price, etc.) related to registered products. The payment type information is information indicating the payment type selected by the customer. The presence or absence of a bag is information indicating whether or not to purchase a shopping bag.

An example of a screen displayed on the customer-side display unit 205 from the start to the end of a transaction in the full-self mode will be described. A “status” used in the following description indicates the status of the POS terminal 20 . Specifically, the status in this embodiment indicates the progress of the transaction in the POS terminal 20 and the usage status of the device. , the status of acquiring some information, and the like. Also, at some point in the transaction, the POS terminal 20 may have multiple statuses. For example, at a certain point in a transaction, it may have a status of displaying a certain screen and a status of acquiring certain information.

When the button 301 is touched, the POS terminal 20 displays a membership card confirmation screen (not shown) for allowing the customer to select whether or not he or she has a membership card. If the customer has a membership card, the customer selects "with membership card" and causes the customer-side scanner unit 206 to read the bar code of the membership card. The POS terminal 20 calls member information specified by the bar code read by the customer-side scanner unit 206 from a server (not shown), and at the same time, displays a screen with the member information added to the screen 310 shown in FIG. , the member information is displayed in part of the screen 310 (for a display example of the member information, see the member information area 355 in FIG. 13, which will be described later). If the customer does not have a membership card, the customer selects "no membership card" on the membership card confirmation screen.

Therefore, in addition to a credit card button 361, an electronic money button 362, and a cash button 363, for example, a "point use button" is displayed on the screen 360, resulting in a four-choice screen. Customers can pay with points by selecting the "use points button". Since the customer has previously acquired member information such as point information on the POS terminal 20, there is no need to display an instruction to read the member information again in the status where the screen 360 is displayed. Also, the POS terminal 20 may display the member information on the screen 360 when the member information is acquired in advance.

The POS terminal 20 issues a receipt and displays a screen 370 when payment is made according to the payment type selected by the customer. FIG. 12 shows the screen 370. As shown in FIG. A screen 370 is a screen for prompting that payment has been completed and receipt of a receipt. FIG. 12 shows a screen when credit is selected as the payment type. A close button 371 is provided on the screen 370 . The close button 371 is a button for deleting the screen 370 . When the Close button 371 is touched, the POS terminal 20 displays the screen 300 . A screen similar to the screen 370 is also displayed in the case of payment by electronic money or payment by cash.

When operating in the semi-self mode, the screen transitions from the screen 300 to the screen 370 described above. The POS terminal 20 displays the transaction information during the period from when the button 301 provided on the screen 300 is touched to when the screen 300 is displayed again after the transaction is completed (hereinafter also referred to as "during transaction"). Generate.

When the self-service POS terminal 20 is left unattended, only the store clerk can often erase the data related to the transaction, such as partially registered products. Therefore, since the status cannot be set to nothing registered by the customer's own operation, there is a problem that other customers cannot use the POS terminal 20 left unattended.

Therefore, in principle, the POS terminal 20 erases the transaction information and returns to the screen 300 when the erasure condition is satisfied during the transaction. The elimination condition is a condition that there is no progress in trading for a certain period of time. Examples of specific erasing conditions include the following erasing conditions (1) to (4).
(1) A certain period of time has elapsed since the customer's touch on the customer-side display unit 205 was no longer detected.
(2) A certain period of time has passed since the barcode was not scanned by the customer-side scanner unit 206 .
(3) When a human sensor is provided, a certain period of time has passed since the human sensor stopped detecting a person. Note that the human sensor may be built in the customer-side scanner unit 206 or the like.

Even if these erasing conditions (1) to (4) are satisfied, exceptionally, among the screens 310, 320, 330, 340, 350, 360, and 370, the POS terminal 20 In statuses displaying 330 and 360, deletion is prohibited. In addition, in the status where the POS terminal 20 has acquired the customer's member information and the customer's point information, deletion is prohibited. A status in which this erasure is prohibited is expressed as a prohibited status.

Screen 330 was a screen for inputting the number of products to be purchased. If the number of items is large, the customer may count the number of items. For example, they sometimes buy dozens of small pieces of chocolate. Thus, when purchasing a large number of products, it takes a certain amount of time to count the number of products. In this case, the erasing conditions (especially erasing conditions (1) and (2)) may be satisfied. When the deletion condition is satisfied and the transaction information is deleted, the customer has to start over again, which is very annoying for the customer. Also, some customers may give up on the purchase and leave the store without purchasing the product. In this case, it becomes an opportunity loss and adversely affects the sales of the store.

Therefore, in the present embodiment, transaction information is exceptionally not deleted on the screen for inputting the number of products even if the deletion condition is satisfied. By doing so, the usability for customers is improved, and opportunity loss does not occur, so that suitable store management can be performed.

Also, the screen 360 is a screen displayed in the status of displaying a screen related to settlement processing. In recent years, the number of payment types has increased dramatically, and some customers use cash, multiple electronic money, and multiple code payments. Furthermore, some customers check the balance of electronic money or code payments before deciding on the type of payment, but it takes a certain amount of time to check the balance. In this case, the erasing conditions (especially erasing conditions (1) and (2)) may be satisfied. When the deletion condition is satisfied and the transaction information is deleted, the customer has to start over again, which is very annoying for the customer. Also, some customers may give up on the purchase and leave the store without purchasing the product. In this case, it becomes an opportunity loss and adversely affects the sales of the store.

Therefore, in this embodiment, even if the deletion condition is satisfied, the transaction information is exceptionally not deleted in the status where the screen related to the settlement process is displayed. By doing so, the usability for customers is improved, and opportunity loss does not occur, so that suitable store management can be performed.

The status in which the POS terminal 20 has acquired the customer's membership information and the customer's point information is a status in which the customer is specified, and in such a status the customer is highly likely to have a purchase intention. If the transaction information is erased, the customer has to start over again, which is very annoying for the customer. Also, some customers may give up on the purchase and leave the store without purchasing the product. In this case, it becomes an opportunity loss and adversely affects the sales of the store.

Therefore, in this embodiment, even if the deletion condition is satisfied, the transaction information is exceptionally not deleted in the status that the POS terminal 20 has acquired the member information of the customer or the point information possessed by the customer. By doing so, the usability for customers is improved, and opportunity loss does not occur, so that suitable store management can be performed. The customer's member information and point information are acquired by reading, for example, a barcode uniquely identifying the customer written on a card lent to the customer by a customer-side scanner.

The POS terminal 20 may accept whether or not the transaction information can be erased, even if the transaction information has a status in which erasure is prohibited. FIG. 13 is a diagram showing an example of a screen that accepts permission to erase transaction information.

FIG. 13 shows the already explained screen 350, but the member information area 355 is displayed by reading the member information and the like. In other words, the status of the POS terminal 20 is a status in which the POS terminal 20 has already acquired the member information of the customer and the point information of the customer. Member information area 355 is, for example, an area that displays a customer number, customer name, and points.

Deletion of transaction information is prohibited in the status where the screen 350 shown in FIG. 13 is displayed. Therefore, the POS terminal 20 displays a pop-up screen 380. FIG. The pop-up screen 380 is an erasure reception screen for accepting permission to erase transaction information. When the customer touches "yes" on the pop-up screen 380, the POS terminal 20 erases the transaction information and displays the screen 300. FIG. On the other hand, when the customer touches "No" on the popup screen 380, the POS terminal 20 clears the popup screen 380 without clearing the transaction information.

After erasing the pop-up screen 380, the POS terminal 20 performs control so that the transaction is resumed from the status immediately before the pop-up screen 380 was displayed. As a result, the display contents of the member information area 355 are maintained. Customers can proceed with the transaction as usual by registering products and touching the checkout button.

However, the POS terminal 20 checks whether the customer who pressed "No" on the pop-up screen 380 is the customer whose member information was read (customer number 12345678 in the case of FIG. 12), and whether the customer with the customer number 12345678 It is impossible to judge whether it is another customer who tries to abuse the information.

Therefore, even if the checkout button is touched after displaying the pop-up screen 380, the POS terminal 20 does not allow the customer to freely operate the "point use button" (the "point use button" may not be displayed). including). Specifically, when the payment type selection screen is displayed, the POS terminal 20 displays "I am sorry, but please read the membership card again".

If the acquired member information is the same as the member information acquired before displaying the pop-up screen 380, the POS terminal 20 displays the four-option screen described above. On the other hand, when the customer touches the button indicating that the member information is not to be read, the POS terminal 20 displays a screen 360 of "point use button" as shown in FIG. As a result, it is possible to prevent fraudulent use of the points of the customer whose member information is read before the pop-up screen 380 is displayed.

By doing so, it is possible to prohibit deletion of the transaction information and also to delete the transaction information. For example, the POS terminal 20 may be set to display a deletion acceptance screen or to delete the transaction information without displaying the deletion acceptance screen, depending on the settings of the store.

FIG. 14 is a flow chart showing the flow of transaction information control processing. The transaction information control process is a process related to deletion of transaction information as described above. Moreover, the transaction information control process is a process performed in a status where any one of the screens 310, 320, 330, 340, 350, 360, and 370 is displayed.

When the deletion condition is satisfied (step S101: YES), the POS terminal 20 determines whether the current status is the prohibited status (step S102). If the status is not prohibited (step S102: NO), the POS terminal 20 erases the transaction information (step S106), displays the standby screen (screen 300) (step S107), and ends the process.

In the case of the prohibited status (step S102: YES), the POS terminal 20 determines whether or not erasure reception is set (step S103). If the deletion acceptance setting has been made (step S103: YES), the POS terminal 20 terminates the process without deleting the transaction information.

If the erasure acceptance setting has been made (step S103: YES), the POS terminal 20 displays an erasure acceptance screen (pop-up screen 380) (step S104). The POS terminal 20 determines whether or not "yes" is touched on the deletion acceptance screen (step S105). If "No" is touched (step S105: NO), the POS terminal 20 terminates the process without erasing the transaction information.

If "yes" is touched (step S105: YES), the POS terminal 20 erases the transaction information (step S106), displays the standby screen (screen 300) (step S107), and ends the process. do.

According to the embodiments described above, it is possible to provide a technique suitable for a full-self sales data processing apparatus. Specifically, when it is determined that the transaction has not progressed for a certain period of time, the transaction information is deleted, so that other customers can use the POS terminal 20 left unattended.
In addition, by displaying the deletion acceptance screen that accepts whether or not to delete transaction information, it is possible to prohibit deletion of transaction information, and it is also possible to delete transaction information. can do.

In the above-described embodiment, the customer touches "yes" or "no" on the pop-up screen 380 for accepting whether or not to erase the transaction information, but the present invention is not limited to this. For example, an in-store situation management device (assist monitor) that collectively monitors the POS terminals 20 in the store displays a screen for accepting whether or not to delete the transaction information, and the transaction information is remotely erased by the clerk using the in-store situation management device. It is good also as the aspect which inputs the propriety of.

The store clerk can determine whether or not to erase the transaction information based on the status of the transaction displayed on the in-store situation management device, the content of the transaction, the length of time the transaction has been left, and the like. That is, the store clerk can determine whether or not to erase without moving to the POS terminal 20 .

In general, a plurality of self-checkout machines (for example, about eight) are installed in one store, and the store clerk who operates the in-store situation management device must always monitor the eight machines. In such a situation, if the clerk leaves the in-store situation management device to enter whether or not to delete the transaction information, the monitoring work will be interrupted, and the presence of the POS terminal 20 causing the abnormality or error will be lost. There is a delay in recognition and response.

Therefore, since the store clerk can determine whether or not to delete the transaction information without moving to the POS terminal 20 as described above, multiple units can be efficiently monitored by the in-store situation management device.

Further, in the present embodiment, the POS terminal 20 operating in full self mode has been described as an example of a sales data processing device, but a device for registering a salesclerk (hereinafter referred to as a "clerk registration device") is not limited to this. do not have. As the salesclerk registration device, a device for registration and settlement by a salesclerk (for example, the POS terminal 20 operating in the above-described normal mode), or a device for only registration by a salesclerk (for example, the above-mentioned POS terminal in the registration-only mode in the semi-self mode). 20).

When the transaction information is deleted, the store clerk registration device may stand by while displaying a registration screen on which new customer's products can be registered. Alternatively, in the operation of the store clerk registration device, in a store clerk registration device that requires input of authentication information for authenticating the store clerk who performs the operation, the user waits while displaying an input screen for entering the authentication information of the store clerk who performs the operation. good too. This is because the store clerk who operated before the transaction information was deleted does not necessarily operate it after the deletion. In this case, the POS terminal 20 erases the authentication information together with the transaction information.

Some store clerk registration devices are capable of coexisting transactions of multiple customers in intermediate statuses. Specifically, among a plurality of transactions, there is a transaction that can be switched as an operation target. Such a switchable store clerk registration device has a switching function of switching a transaction screen to be operated. The switching function switches, for example, according to an operation on tabs showing each of a plurality of transactions. The switchable store clerk registration device treats transactions that are not subject to operation as pending transactions.

The transaction information control process of this embodiment can be applied to the switchable store clerk registration device. Specifically, for example, when a certain period of time elapses without detection of an operation by a sales clerk, the switchable sales clerk registration device changes the transaction information of the current operation target transaction to the transaction information of the pending transaction, and adds new transaction information. to display a screen that can accept any kind of transaction.

As a case where a certain period of time passes without detection of the operation by the clerk, when the clerk is registering the product of customer A, there is an inquiry from the customer A, and the customer A and the clerk leave the cash register and take the product to the sales floor. For example, the case of going to In this case, if only the clerk returns to the switchable clerk registration device after a certain period of time has passed, the transaction information corresponding to the transaction of customer A becomes pending transaction information, and a new transaction can be accepted on the screen. is displayed, a new transaction for another customer B can be started smoothly.

In the above-described embodiment, the processing related to erasure of transaction information has been described, and the end timing of the recording period by the imaging unit 216 in this case will be described. The timing to start recording is five seconds before pressing the button 301 in FIG. 5 as described above, or at the same time as pressing the button. After that, when the deletion condition is satisfied, the POS terminal 20 deletes the transaction information and terminates the recording.

In the screen 350 shown in FIG. 13 that is displayed when the member information is acquired (the status that the POS terminal 20 has already acquired the point information owned by the customer), a pop-up screen 380 for accepting whether or not to delete the transaction information is displayed. is displayed, when the customer touches "yes" on the pop-up screen 380, the POS terminal 20 erases the transaction information, ends the recording, and displays the screen 300. FIG. On the other hand, when the customer touches "Yes" on the pop-up screen 380, the POS terminal 20 continues the recording without ending it, and ends the recording when the transaction ends. In this way, the recording end timing is timing according to the mode of erasing the transaction information.
