That is, in one embodiment, the control unit 301 is a processor that is programmed to carry out the functions of the communication control unit 3001, the operation control unit 3002, the accounting control unit 3003, the abnormality detecting unit 3004, the mode control unit 3005, the state managing unit 3006, the display control unit 3007, and the information transfer unit 3008. In another embodiment, the control unit 301 is a hardware controller, e.g., an application specific integrated circuit (ASIC) and field programmable gate array (FPGA), that is configured to carry out the functions of the communication control unit 3001, the operation control unit 3002, the accounting control unit 3003, the abnormality detecting unit 3004, the mode control unit 3005, the state managing unit 3006, the display control unit 3007, and the information transfer unit 3008.

The communication control unit 3001 is an example of the receiving unit. For example, the communication control unit 3001 controls the communication interface 303 and controls communication with the registration apparatus 20, the other accounting apparatuses 30, and the like. For example, the communication control unit 3001 receives sales registration information from the registration apparatus 20.

The operation control unit 3002 receives operation inputs from the touch panel 361.

The accounting control unit 3003 is an example of the accounting control unit. The accounting control unit 3003 controls execution of accounting processing of a purchase target commodity on the basis of the sales registration information received by the communication control unit 3001. For example, when the communication control unit 3001 receives the sales registration information, the accounting control unit 3003 executes the accounting processing on the basis of the sales registration information. The accounting control unit 3003 displays a total amount of commodities and the like on the display unit 360 and requests payment from the customer. If the payment is made by cash, the accounting control unit 3003 causes the change unit 320 to store the paid cash. If there is change, the accounting control unit 3003 causes the change unit 320 to discharge the change.

The abnormality detecting unit 3004 is an example of a detecting unit. The abnormality detecting unit 3004 detects an abnormality such as a failure that occurs in the accounting apparatus 30. For example, the abnormality detecting unit 3004 detects an abnormality concerning storage amounts of coins and bills stored in the change unit 320. That is, the abnormality detecting unit 3004 detects that the coins and the bills stored in the change unit 320 run short or that the change unit 320 is full of coins and/or bills. The abnormality detecting unit 3004 also detects that the change unit 320 is jammed by a coin or a bill. The abnormality detecting unit 3004 detects that paper of the printer 330 runs short.

The mode control unit 3005 controls modes of the accounting apparatus 30. The modes of the accounting apparatus 30 include a customer mode and a store clerk mode. The customer mode is a mode in which the customer executes the accounting processing. The store clerk mode is a mode in which the store clerk operates the accounting device 30. That is, the store clerk mode is a mode set when the store clerk performs maintenance or the like of the accounting apparatus 30. The mode control unit 3005 changes the mode to the store clerk mode from the customer mode based on a condition that information indicating that the store clerk has authority to shift to the store clerk mode is input. The information indicating that the store clerk has the authority to shift to the store clerk mode is, for example, a store clerk code and a password that identifies the store clerk. The mode control unit 3005 sets the mode of the accounting apparatus 30 to the customer mode based on a condition that the operation control unit 3002 receives an operation for setting the accounting apparatus 30 to the customer mode.

The state managing unit 3006 manages states of the apparatuses of the semi-self-service checkout system 1. For example, if the communication control unit 3001 receives apparatus state information from each of the accounting apparatuses 30 of the semi-self-service checkout system 1, the state managing unit 3006 stores the apparatus state information in the apparatus state information table 306. Every time a predetermined time elapses or every time a state of the accounting apparatus 30 changes, the state managing unit 3006 causes the communication control unit 3001 to transmit the apparatus state information indicating the state of the accounting apparatus 30 to the other accounting apparatuses 30.

The display control unit 3007 is an example of the display control unit. The display control unit 3007 causes the display unit 360 to display various screens. For example, when the abnormality detecting unit 3004 detects abnormality, the display control unit 3007 causes the display unit 360 to display a calling screen indicating that the store clerk is being called. The display control unit 3007 causes the display unit 360 to display a transfer confirmation screen 3100 when the store clerk code or the like is input on the calling screen and the accounting apparatus 30 is set to the store clerk mode.

FIG. 7 is a diagram showing an example of the transfer confirmation screen 3100. The transfer confirmation screen 3100 is a screen for confirming whether to transfer sales registration information. The transfer confirmation screen 3100 includes a mode display region 3110, an apparatus display region 3120, an abnormality display region 3130, and a transfer confirmation region 3140. The mode display region 3110 is a region indicating a present mode. The apparatus display region 3120 is a region for displaying an identification of the accounting apparatus 30 and the registration apparatus 20 that transmits sales registration information used for the accounting processing currently being executed. The abnormality display region 3130 is a region for displaying abnormality detected by the abnormality detecting unit 3004. The store clerk determines, according to details of the abnormality displayed in the abnormality display region 3130, whether the sales registration information should be transferred in order to execute the accounting processing in the other accounting apparatuses 30 or whether the abnormality of the accounting apparatus 30 should be solved. The transfer confirmation region 3140 is a region for inputting whether the sales registration information is transferred.

The transfer confirmation region 3140 includes a YES button 3141 and a NO button 3142. The YES button 3141 is a button for inputting operation to indicate that the sales registration information is transferred. That is, the YES button 3141 is a button for displaying an apparatus selection screen 3200 (see FIG. 8). The NO button 3142 is a button for inputting operation to indicate that the sales registration information is not transferred. That is, the NO button 3142 is a button pressed if, even if an abnormality occurs in the accounting apparatus 30, the abnormality of the accounting apparatus 30 is resolved and the accounting processing is to be performed in the accounting apparatus 30. For example, if the change unit 320 is jammed by a coin or the like before a total amount input by the customer is identified, since a change amount or the like that should be refunded to the customer is unknown, the store clerk should resolve the abnormality of the accounting apparatus 30. In such a case, the NO button 3142 is pressed. In this way, the abnormality of the accounting apparatus 30 should be resolved in some cases. If the decision concerning whether the sales registration information is transferred is left to the customer, it is likely that an unexpected trouble occurs. Therefore, the display control unit 3007 causes the display unit 360 to display the transfer confirmation screen 3100 only after the store clerk code is input.

FIG. 8 is a diagram showing an example of the apparatus selection screen 3200. The apparatus selection screen 3200 is a screen for allowing the customer to select, instead of the current accounting apparatus 30, an alternative apparatus that executes the accounting processing. The alternative apparatus is, for example, a different accounting apparatus 30. The display control unit 3007 causes the display unit 360 to display the apparatus selection screen 3200 when the accounting apparatus 30 is in the store clerk mode. That is, the display control unit 3007 causes the display unit 360 to display the apparatus selection screen 3200 when the store clerk code is input as information indicating that the store clerk has the shift authority.

The apparatus selection screen 3200 includes a mode display region 3210, an apparatus display region 3220, an abnormality display region 3230, and an apparatus selection region 3240. The mode display region 3210, the apparatus display region 3220, and the abnormality display region 3230 are regions for displaying the same contents as the contents displayed in the mode display region 3110, the apparatus display region 3120, and the abnormality display region 3130 of the transfer confirmation screen 3100. The apparatus selection region 3240 is a region in which an apparatus selection button 3241 for selecting an alternative apparatus is displayed.

The display control unit 3007 displays, on the basis of the apparatus state information table 306, one or more apparatus selection buttons 3241 for selecting an alternative apparatus. The apparatus selection button 3241 includes a type of an apparatus, an apparatus code capable of identifying the apparatus, and state information indicating a state of the apparatus. The display control unit 3007 causes the display unit 360 to display the apparatus selection button 3241 so as distinguish the accounting apparatus 30 capable of executing the accounting processing from the accounting apparatus 30 incapable of executing the accounting processing. That is, the display control unit 3007 grays out, on the basis of the state information of the apparatuses stored in the apparatus state information table 306, the accounting apparatus 30 that cannot execute the accounting processing because, for example, the accounting apparatus 30 is in use. In the case that the accounting apparatus 30 is not in use or the like, the display control unit 3007 determines that the accounting processing is executable. On the other hand, in the case that the accounting apparatus is in use, store clerk has been called, a failure mode, or the like, the display control unit 3007 determines that the accounting processing is unexecutable. In the apparatus selection screen 3200 shown in FIG. 8, “T002” and “T005” are grayed-out as the un-selectable accounting apparatuses 30. Note that a method of displaying un-selectable accounting apparatuses 30 is not limited to being grayed-out. For example, the display control unit 3007 may clearly indicate with characters, figures, or the like that certain accounting apparatuses 30 are un-selectable or may not display the apparatus selection buttons 3241 of the un-selectable accounting apparatuses 30.

FIG. 9 is a diagram showing an example of the transfer completion screen 3300. The transfer completion screen 3300 is a screen for displaying completion of transfer of sales registration information to an apparatus selected by the apparatus selection button 3241 in the apparatus selection screen 3200. The transfer completion screen 3300 includes a mode display region 3310, an apparatus display region 3320, an abnormality display region 3330, and a completion display region 3340. The mode display region 3310, the apparatus display region 3320, and the abnormality display region 3330 are regions for displaying the same contents as the contents of the mode display region 3110, the apparatus display region 3120, and the abnormality display region 3130 of the transfer confirmation screen 3100. The completion display region 3340 is a region for displaying the completion of the transfer of the sales registration information. The accounting apparatus 30 that transfers the sales registration information is displayed in the completion display region 3340. Further, a confirmation button 3341 is displayed in the completion display region 3340. The confirmation button 3341 is a button for inputting confirmation of the accounting apparatus 30 at a transfer destination to which the sales registration information is transferred.

The information transfer unit 3008 is an example of the changing unit and the transmitting unit. The information transfer unit 3008 designates, as an alternative apparatus, the accounting apparatus 30 selected in the apparatus selection screen 3200. That is, the information transfer unit 3008 changes the accounting apparatus 30 that executes the accounting processing to the alternative apparatus selected on the apparatus selection screen 3200. The information transfer unit 3008 causes, on the basis of a result of the designation, the communication control unit 3001 to transmit the sales registration information. That is, the information transfer unit 3008 transmits, in cooperation with the communication control unit 3001, the sales registration information to the designated accounting apparatus 30.

Transfer processing executed by the accounting apparatus 30 is explained. FIG. 10 is a flowchart illustrating an example of the transfer processing executed by the accounting apparatus 30 according to the embodiment.

The abnormality detecting unit 3004 detects an abnormality (Act S1). The display control unit 3007 causes the display unit 360 to display a calling screen indicating that the store clerk is being called (Act S2). The operation control unit 3002 stays on standby until an operation for changing the mode of the accounting apparatus 30 to the store clerk mode is received (No in Act S3).

On the other hand, when the operation for changing the mode of the accounting apparatus 30 to the store clerk mode is received (Yes in Act S3), the mode control unit 3005 shifts the accounting apparatus 30 to the store clerk mode (Act S4). The display control unit 3007 causes the display unit 360 to display the transfer confirmation screen 3100 (Act S5).

When the YES button 3141 of the transfer confirmation screen 3100 is not pressed (No in Act S6) and the NO button 3142 is not pressed (No in Act S7), the operation control unit 3002 returns to Act S6. On the other hand, when the pressing of the NO button 3142 is received (Yes in Act S7), the accounting apparatus 30 receives solution processing for solving detected abnormality (Act S8).

On the other hand, when the pressing of the YES button 3141 is received (Yes in Act S6), the display control unit 3007 causes the display unit 360 to display the apparatus selection screen 3200 (Act S9). The operation control unit 3002 determines whether pressing of the apparatus selection button 3241 on the apparatus selection screen 3200 is received (Act S10). The accounting apparatus 30 waits until the pressing of the apparatus selection button 3241 is received (No in Act S10).

When the pressing of the apparatus selection button 3241 is received (Yes in Act S10), the communication control unit 3001 transmits sales registration information to an apparatus indicated by the pressed apparatus selection button 3241 (Act S11). The display control unit 3007 causes the display unit 360 to display the transfer completion screen 3300 (Act S12).

Consequently, the accounting apparatus 30 ends the transfer processing.

As explained above, with the semi-self-service checkout system 1 according to the embodiment, if an abnormality such as a failure occurs in the accounting apparatus 30, the accounting apparatus 30 causes the display unit 360 to display the apparatus selection screen 3200 for causing the customer to select an alternative apparatus to execute the accounting processing. The accounting apparatus 30 designates, as the alternative apparatus, the accounting apparatus 30 selected on the apparatus selection screen 3200. The accounting apparatus 30 transmits the sales registration information to the designated accounting apparatus 30. Consequently, the store clerk directs the customer to the designated accounting apparatus 30. Therefore, the customer can perform the accounting processing in the new accounting apparatus 30 without waiting for the work to resolving the abnormality or the like that occurs in the accounting apparatus 30. Therefore, the accounting apparatus 30 according to the embodiment can improve convenience of the customer.

The embodiment is explained above. However, the embodiment is presented as an example and is not intended to limit the scope of the invention. The new embodiment can be implemented in other various forms. Various omissions, replacements, and changes of the embodiment can be performed without departing from the spirit of the invention. The embodiment and modifications of the embodiment are included in the scope and the gist of the invention and included in the inventions described in claims and the scope of equivalents of the inventions.

In the embodiment, it is explained that the alternative apparatus is, for example, another accounting apparatus 30. However, the alternative apparatus is not limited to another accounting apparatus 30. For example, the apparatus that executes the accounting processing may be a POS (Point of Sales) terminal or the like instead of the accounting apparatus 30. In this case, the display control unit 3007 causes the display unit 360 to display an apparatus capable of executing the accounting processing on the apparatus selection screen 3200. The information transfer unit 3008 causes the communication control unit 3001 to transmit the sales registration information to the apparatus selected on the apparatus selection screen 3200.

In the embodiment, the information transfer unit 3008 transmits the sales registration information to the designated accounting apparatus 30 in cooperation with the communication control unit 3001. However, the information transfer unit 3008 may transmit the sales registration information to the designated accounting apparatus 30 via another apparatus such as a store server or the registration apparatus 20. Further, if the sales registration information is stored in the other apparatus such as the store server or the registration apparatus 20, the information transfer unit 3008 may not transmit the sales registration information. In this case, the information transfer unit 3008 notifies the designated accounting apparatus 30 of the other apparatus in which the sales registration information is stored such as the store server or the registration apparatus 20. The other apparatus in which the sales registration information is stored may transmit the sales registration information to the designated accounting apparatus 30.

In the embodiment, the example is explained in which the checkout system includes the accounting apparatus 30. However, the checkout system can also include apparatuses other than the accounting apparatus 30. For example, the checkout system can include a server apparatus and a client apparatus. In this case, the server apparatus is, for example, an apparatus such as a personal computer or a cloud service for providing computer resources such as hardware and software. The client apparatus may be, for example, an apparatus that exclusively executes the accounting processing or may be a general-purpose apparatus such as a tablet terminal. In this case, the server apparatus receives the sales registration information from the registration apparatus 20. The server apparatus generates, according to a request from the client apparatus, screen information for causing the client apparatus to display various screens such as the calling screen, the apparatus selection screen 3200, the transfer confirmation screen 3100, and the transfer completion screen 3300. The server apparatus transmits the screen information to the client apparatus. Consequently, the server apparatus can designate, as the alternative apparatus, another client apparatus selected on the apparatus selection screen 3200 displayed by the client apparatus. That is, the server apparatus can change, to the alternative apparatus, an alternative apparatus to execute the accounting processing. The client apparatus designated as the alternative apparatus can execute the accounting processing.

The checkout system may be applied to an attendant apparatus that displays states of the accounting apparatuses 30 set in the store. The attendant apparatus may be a POS terminal, may be a personal computer, or may be a tablet terminal. In this case, if an abnormality of the accounting apparatus 30 is detected, the attendant apparatus causes the display unit 360 to display the apparatus selection screen 3200. Further, the attendant apparatus causes, according to received operation, the display unit 360 to display the transfer confirmation screen 3100 or the transfer completion screen 3300. Consequently, the attendant apparatus can designate, as the alternative apparatus, the accounting apparatus 30 selected on the apparatus selection screen 3200. That is, the attendant apparatus can change, to the alternative apparatus, an apparatus that executes the accounting processing. The accounting apparatus 30 designated as the alternative apparatus can execute the accounting processing.

The computer programs executed by the apparatuses in the embodiment and the modifications are provided while being incorporated in advance in storage media (ROMs or storing units) included in the apparatuses. However, the computer programs are not limited to this. For example, the computer programs may be provided while being recorded in a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a DVD (Digital Versatile Disk) as a file of an installable format or an executable format. Further, the storage media are not limited to media independent from a computer or an incorporated system and include storage media in which the computer programs transmitted by a LAN, the Internet, or the like are downloaded and stored or temporarily stored.

The computer programs executed by the apparatuses in the embodiment and the modifications may be stored on a computer connected to a network such as the Internet and may be provided by being downloaded through the network or may be provided or distributed through the network such as the Internet.
