Description

  The present invention relates to a POS system.

  2. Description of the Related Art Conventionally, a system including a registration device and a payment device connected via a network is known (see, for example, Patent Document 1). In the system in which the registration device and the payment device are separated as described above, the payment device executes the payment processing using the transaction information in the registration device. In the system as described above, it is necessary to prevent the settlement process from being executed many times from one transaction information. For example, information indicating that the transaction information called to the settlement apparatus has been called is retained, and the transaction information is referred to by referring to the information indicating that the transaction has been completed before sending the transaction information to the settlement apparatus. For example, a method of restricting calls to the reimbursement device can be considered.

Japanese Patent Laid-Open No. 2-184959

  However, in the event that the power of the checkout device during the checkout process is shut down for some reason such as a power outage, the transaction information that was in the checkout process is still called, so that the checkout process can be resumed. If you try to call it again, you can't call it. Therefore, it takes time and labor, such as redoing the registration process (product registration) from the beginning in the registration device.

  The present invention has been made in consideration of such circumstances, and the purpose of the present invention is when the power is turned off before or during the settlement process in a system including a registration apparatus and a settlement apparatus. However, it is in providing the technique which can restart a checkout process rapidly.

  In order to solve the above-described problem, a POS system according to an aspect of the present invention executes a checkout process using a registration apparatus that executes a registration process for registering a product and transaction information generated in the registration process. A POS system having a settlement apparatus, comprising: a supply means for supplying or assigning the transaction information to the settlement apparatus; and a release means for releasing supply or assignment of the transaction information by the supply means. And

  According to the POS system, the transaction information supplied to the settlement apparatus (transaction information transmitted to the settlement apparatus) or the transaction information assigned to the settlement apparatus (designation of the settlement apparatus that processes the transaction information is specified. Even if it is transaction information), it can be supplied again to the settlement apparatus if cancellation (call back processing) is performed. Therefore, even when the power of the settlement apparatus is turned off before the settlement process or during the settlement process, the settlement process can be resumed quickly without taking any trouble.

  The POS system includes display means for displaying the transaction information of an unsettled transaction that is a transaction for which the settlement process has not been completed so as to be identifiable to a user, and the release unit is responsive to a user's designated operation The designation cancellation means for canceling the supply or the allocation, the designation cancellation means, among the transaction information of the unsettled transaction displayed in an identifiable manner, the transaction information specified by the designation operation Supply or assignment may be canceled.

  According to the POS system, it can be canceled as necessary.

  In the POS system, the canceling unit may delete the allocated information stored based on the supply or allocation of the transaction information as the cancellation of the supply or allocation of the transaction information.

  According to the POS system, release can be controlled easily.

  In the POS system, allocated information storage means for storing allocated information based on the supply or allocation of the transaction information, and stored based on the supply or allocation of the transaction information and based on the transaction information A during-settlement information storage unit that stores information being settled that is erased upon completion of the settlement process, and a settlement information storage unit that stores settlement information stored upon completion of the settlement process based on the transaction information. The release means has automatic release means for releasing the supply or allocation without user operation, and the information during adjustment is also erased even when the payment apparatus is turned off. The automatic cancellation means is a transaction in which the assigned information is stored, and the transaction information of a transaction in which the adjusted information is not stored. When the settlement in information is not stored, by erasing the allocated information, may be released the feed or assignment.

  According to the POS system, it can be automatically canceled.

The settlement apparatus is
You may make it provide the cancellation | release information transmission means which transmits the cancellation | release information regarding the cancellation | release of the said supply or the allocation of the said transaction information, when the said adjustment process cannot be performed.

  According to the POS system, when the payment process cannot be executed (when the power is turned off, when an error occurs in the change machine 210, when offline, when the error occurs in the printing unit 209, the payment process is normally executed. When a fatal operating state that cannot be performed or has become, or when an event to notify that the operating state has been reached or has occurred, release information (for example, to the registration device that performs the release) (for example, , A call back confirmation request, a call back request, etc.).

  In the POS system, the settlement apparatus may include cancellation information transmission means for transmitting the cancellation information when the power is turned off so that the settlement process cannot be executed.

  According to the POS system, when power is turned off, release information (for example, a call back confirmation request, a call back request, etc.) can be transmitted to a registration device that executes the release. Note that when “power is turned off”, for example, a power-off operation (for example, the first power-off operation shown in FIG. 15) is detected, and a process for setting the power-off state is executed to actually turn on the power. Any time point (timing) between the detection of the power-off operation and the actual power-off state is included in the settlement apparatus that is turned off. Therefore, “send the release information to the registration device when the power is turned off” may be a mode in which the release information is sent to the registration device immediately after the detection of the power-off operation. The mode may be such that the release information is transmitted to the registration device immediately before detection and immediately after the power is actually turned off. In other words, “when the power is turned off” includes any timing as long as it is a timing before activation in a series of operations at the time of rebooting. Note that the process of transmitting the release information to the registration device may or may not be regarded as one of the processes for turning the power off.

  In the POS system, the settlement apparatus may include a cancellation information transmission unit that transmits the cancellation information when the power is turned on after the power is turned off so that the settlement process cannot be executed.

  According to the POS system, when the power is turned on after the power is turned off, release information (for example, a call back confirmation request, a call back request, etc.) can be transmitted to the registration device that executes the release. It should be noted that “when the power is turned on after the power is turned off”, for example, a power-off operation (for example, the second power-off operation shown in FIG. 19) is detected and a process for turning the power off is executed. In the payment device that turns on the power after executing the process to turn on the power after the power is actually turned off, the power is actually turned on after the power is turned off after detecting the power off operation. Any point in time (timing) is included. In addition, when the power is turned on after the power is turned off, if it is normal (when the release information is not sent to the registration device), the customer can execute the settlement process after the power is turned on. The time until it becomes is also included. In other words, “when the power is turned on after the power is turned off”, after the start-up in a series of operations at the time of restart, before the settlement process can be executed (for example, in step S67 of FIG. 15 or FIG. 19). Any timing is included as long as it is the timing before the display in step S167 shown.

  In the POS system, the registration device includes release information reception notification means for notifying reception of the release information, and when the release information reception notification means receives the release information, the settlement process is completed. You may make it alert | report reception of the said cancellation | release information in the screen which displays the said transaction information of the unsettled transaction which is a transaction which is not.

  According to the POS system, it is possible to easily confirm on the list (for example, unsettled list screen, unsettled called list) that cancellation is necessary.

  In the POS system, the registration device includes a release information reception notification unit that notifies reception of the release information, and the release information reception notification unit performs the registration process when the release information is received. In this screen, the reception of the release information may be notified.

  According to the POS system, it is possible to easily confirm that cancellation is necessary when a product is registered.

  In the POS system, the registration device is automatically canceled when the supply or allocation of the transaction information is canceled based on the cancellation information by the cancellation unit without the user's operation. There may be provided automatic release notification means for informing the effect, and the automatic release notification means may notify that the release has been automatically performed on the screen for executing the registration process.

  According to the POS system, it is possible to easily confirm that the release has been automatically performed when the product is registered.

  According to the present invention, in a system including a registration device and a payment device, the payment processing can be quickly resumed even if the power is turned off before or during the payment processing.

[First Embodiment]
A first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a POS system 1 according to a first embodiment of the present invention (a POS system 2 according to a second embodiment (described later) and a POS system 3 according to a third embodiment (described later)). It is a perspective view showing a mode. The POS system 1 is installed on the store floor. The POS system 1 includes a registration device 10, a checkout device 20, and a store controller 30 (not shown in FIG. 1).

  The registration device 10 is a device that mainly performs registration processing for registering products. In FIG. 1, the registration device 10 is installed in a product registration counter 11. The store clerk (operator) S operates the registration device 10 to cause the registration device 10 to execute a registration process. In addition, the number of the registration apparatuses 10 illustrated is an example.

  The settlement apparatus 20 is an apparatus that mainly performs a settlement process that settles the purchased product registered by the registration process 10. In FIG. 1, the settlement apparatus 20 is installed in a settlement counter 21. After completing the registration process, the customer C moves to the installation location of the settlement apparatus 20, operates the settlement apparatus 20, and causes the settlement apparatus 20 to execute the settlement process. In addition, the number of the adjustment apparatuses 20 shown in figure is an example.

  The store controller 30 is a computer (server) that communicates with each device on the store floor (registration processing 10, checkout device 20), a device outside the store (for example, a headquarter device), and the like. The store controller 30 is installed in a store backyard (not shown).

  The registration process 10 generates transaction information in the registration process. The transaction information is a log file including a transaction number (transaction specifying information) for specifying (identifying) each transaction and detailed information of each transaction. The settlement apparatus 20 acquires the transaction information generated in the registration process 10 and executes the settlement process using the acquired transaction information. There are various modes in which the settlement apparatus 20 acquires transaction information, in other words, the registration process 10 supplies transaction information to the settlement apparatus 20.

(Mode for supplying transaction information using a bill (registered trademark) printed with a one-dimensional barcode)
The registration process 10 issues an accounting ticket on which a barcode obtained by converting a transaction number into a one-dimensional barcode is printed. The checkout apparatus 20 acquires a transaction number from the barcode printed on the bill, and requests the registration process 10 for transaction information of the transaction number. The registration process 10 transmits transaction information to the settlement apparatus 20 in response to a request from the settlement apparatus 20.

(Mode for supplying transaction information using a bill printed with a two-dimensional code)
The registration process 10 issues a bill that prints a two-dimensional code (for example, a QR code (registered trademark)) obtained by converting the transaction information into a two-dimensional code. The checkout apparatus 20 acquires transaction information from the two-dimensional code printed on the bill.

(Mode in which transaction information is supplied by specifying the settlement apparatus 20)
The registration process 10 receives an input designated by the payment apparatus 20 that executes the payment process from the store clerk. The registration process 10 transmits transaction information to the designated settlement apparatus 20 when the settlement apparatus 20 is designated. In addition, the registration process 10 does not transmit the transaction information when the settlement apparatus 20 is designated, but instead performs the settlement when a predetermined operation (for example, screen touch) is performed in the designated settlement apparatus 20. Transaction information may be transmitted to the designated settlement apparatus 20 in response to a request from the apparatus 20.

  Further, in this specification, “transaction information supply” means that transaction information is transmitted to the settlement apparatus 20 and that the settlement apparatus 20 acquires transaction information via a bill printed with a two-dimensional code. Called. In addition, designating the settlement apparatus 20 that transmits transaction information is also referred to as “transaction information allocation”. Therefore, for example, when the supply of transaction information to the settlement apparatus 20 is controlled, the transmission of the transaction information to the settlement apparatus 20 is controlled, and the bills in the settlement apparatus 20 (accounts printed with a two-dimensional code are printed. Control of acquisition of transaction information from a ticket) and control of reissuance of an accounting ticket printed with a two-dimensional code obtained by converting the same transaction information into a two-dimensional code. In addition, controlling the allocation of transaction information to the settlement apparatus 20 includes controlling the designation of the settlement apparatus 20. The same applies to when the supply of transaction information to the settlement apparatus 20 is prohibited (and the prohibition is canceled), and when the allocation of transaction information to the settlement apparatus 20 is prohibited (and the prohibition is canceled).

  FIG. 2 is a block diagram showing a configuration example of the POS system 1 in the first embodiment (the POS system 2 in the second embodiment (described later) and the POS system 3 in the third embodiment (described later)). is there. As shown in FIG. 2, each registration device 10 (registration devices 10-1, 10-2,...), Each payment device 20 (the payment devices 20-1, 20-2,...), And the store controller 30 are And are communicably connected via the LAN 40. Since the registration devices 10-1, 10-2,... Have the same configuration, they are collectively referred to as the registration device 10 as in FIG. Since the settlement apparatuses 20-1, 20-2,... Have the same configuration, they are collectively referred to as the settlement apparatus 20 as in FIG. In addition to the above, a monitoring device 31 (not shown) that monitors the processing status of the registration device 10 and the payment device 20 may be connected to the LAN 40.

  First, the store controller 30 will be described. The store controller 30 includes at least a control unit (referred to as a store controller control unit, not shown), a storage unit (referred to as a store controller storage unit, not shown), and a communication unit (referred to as a store controller communication unit, not shown). And comprising. The store controller control unit controls the entire store controller 30.

  The store controller storage unit stores various information. For example, the store controller storage unit stores the product file as a master file. The product file is a master file including a product code (for example, JAN), a product name, and a sales price. The store controller storage unit stores transaction information.

  The store controller communication unit transmits and receives various types of information under the control of the store controller control unit. For example, the store controller communication unit receives a product file from the outside (for example, a server at the headquarters) and stores it in the store controller storage unit. Further, the store controller communication unit transmits (distributes) the product file stored in the store controller storage unit to the registration device 10 and the payment device 20. Further, the store controller communication unit receives transaction information from the registration device 10 and stores it in the store controller storage unit.

  Next, the registration device 10 will be described. FIG. 3 is a block diagram showing a configuration example of the registration apparatus 10 in the first embodiment (a POS system 2 in the second embodiment (described later) and a POS system 2 in the third embodiment (described later)). is there. As illustrated in FIG. 3, the registration device 10 includes a CPU 101, a ROM 102, a RAM 103, a scanner unit 104, a store clerk display unit 105, a customer display unit 106, a hard disk 107, and a store clerk operation unit 108. A communication unit 109, a buzzer 110, a printing unit 111, and a bus 112. These are connected to each other via a bus 112.

  The CPU 101 controls the entire registration apparatus 10 by expanding and executing a program stored in the ROM 102 in the RAM 103. Details will be described later.

  The ROM 102 stores various information. For example, the ROM 102 stores a program executed by the CPU 101, a device number of the own device (device identification information), and the like.

  The RAM 103 temporarily stores various information. For example, the RAM 103 temporarily stores a program read from the ROM 102 and information acquired or generated by execution of the program (for example, various determination results, transaction information, and read information). Note that the RAM 103 may temporarily store a product file or an unsettled call file (transmission prohibition list; FIG. 4).

  The scanner unit 104 optically reads a barcode attached to a product and acquires a product code of the product (acquires the product code that has been encoded by reverse conversion). The scanner unit 104 notifies the CPU 101 of the acquired product code. In addition, the scanner unit 104 optically reads a barcode attached to a name tag or the like of the clerk S, and acquires person-in-charge identification information (for example, person-in-charge code, person-in-charge name) that identifies the clerk S. The scanner unit 104 notifies the CPU 101 of the acquired person-in-charge identification information.

  The clerk display unit 105 is, for example, a liquid crystal touch display device that displays information on the clerk S, and can accept operations of the clerk S, for example. Information displayed on the display unit 105 for the store clerk includes, for example, a menu screen, processing information for registration processing (for example, product name, number of purchases, sales price, total price), various messages, unsettled call file The unsettled call list based on (transmission prohibition inquiry. FIG. 4).

  The store clerk display unit 105 may display various GUI operation buttons having the same functions as the operation buttons (described later) provided in the store clerk operation unit 108 instead of the store clerk operation unit 108. The store clerk display unit 105 may display a preset button for registering a predetermined product (for example, fresh food). In the clerk display unit 105, when the clerk S is operated, an operation signal is notified to the CPU 101.

  The customer display unit 106 is, for example, a liquid crystal display device that displays information on the customer C. Information displayed on the customer display unit 106 is, for example, processing information of a registration process, a message, an advertisement, and the like. The customer display unit 106 may be, for example, a liquid crystal touch display device that can accept the operation of the customer C, like the store clerk display unit 105. For example, the customer display unit 106 accepts an operation for a message (for example, confirmation of the amount of a utility bill). When the customer C performs an operation on the customer display unit 106, an operation signal is notified to the CPU 101.

  The hard disk 107 stores various information. For example, the hard disk 107 stores a product file transmitted from the store controller 30 and received by the communication unit 109. The hard disk 107 stores an unsettled call file. Note that the hard disk 107 may store the above-described program instead of the ROM 102.

  The salesclerk operation unit 108 includes various operation buttons (operation keys). For example, the clerk operation unit 108 issues a numeric button (numeric key) for inputting a number, a current total button (current key) for completing a transaction registration process, and a bill (FIG. 5). An issue button (issuance key) for inputting, a confirmation button (confirmation key) for inputting an intention of confirmation, a cancel button (cancellation key) for inputting an intention of cancellation, and the like. The salesclerk operation unit 108 may include the above-described preset button (preset key). In the clerk operation unit 108, when the clerk S is operated, an operation signal is notified to the CPU 101.

  The communication unit 109 is a communication interface for communicating with an external device via the LAN 40. The buzzer 110 is a sound generating unit for generating a confirmation sound, a warning sound, and the like. The printing unit 111 prints and issues a medium such as a bill.

  When the CPU 101 acquires person-in-charge identification information via the scanner unit 104 (when a barcode attached to a name tag or the like is read by the scanner unit 104), the CPU 101 temporarily stores the person-in-charge identification information in the RAM 103.

  Further, when the product code is acquired via the scanner unit 104 (when the barcode attached to the product is read by the scanner unit 104), the CPU 101 refers to the product file stored in the hard disk 107 and purchases the product code. The product name and sales price of the product are specified, and the product name, sales price, and number of purchases of each purchased product are temporarily stored in the RAM 103. That is, the registration process is executed.

  In addition, the CPU 101 displays information on the purchased product, a message, and the like on the salesclerk display unit 105 and the customer display unit 106 in accordance with the progress of the registration process.

  The CPU 101 generates transaction information after completing the registration process. For example, the CPU 101 receives transaction information (transaction number and detailed information) based on information temporarily stored in the RAM 103 or information stored in the ROM 102 when an operation signal for pressing the current total button is notified. Generate. The transaction number may be, for example, a number configured from a device number of the own device and a unique number (for example, a serial number) assigned for each transaction. The detailed information only needs to include, for example, a device number, person-in-charge identification information, transaction date and time, total amount, product name (or product code), subtotal amount, number of purchases, and the like. After the transaction information is generated, the CPU 101 temporarily stores the generated transaction information in the RAM 103.

  After completing the registration process, the CPU 101 controls the communication unit 109 to transmit the transaction information of the registration process to the store controller 30. In addition, after completing the registration process, the CPU 101 controls the printing unit 111 to convert the transaction number of the transaction information of the registration process into a barcode and issue a printed bill. Note that the bill is processed (read) by the settlement apparatus 20.

  When the transaction information is requested from the settlement apparatus 20 via the communication unit 109, the CPU 101 specifies the requested transaction information based on the transaction number included in the request (request information). The CPU 101 determines whether or not the specified transaction information (requested transaction information) corresponds to unsettled call transaction information. The unsettled call transaction information is transaction information that has not been processed (settlement processing) in the settlement device 20 among the transaction information already transmitted to the settlement device 20. When the specified transaction information does not correspond to the unsettled call-completed transaction information, the CPU 101 acquires the transaction information from the RAM 103 and transmits it to the requesting settlement apparatus 20. On the other hand, when the identified transaction information corresponds to the unpaid call-up transaction information, the CPU 101 does not transmit the transaction information to the requesting settlement apparatus 20. When the identified transaction information corresponds to the unpaid call-up transaction information, the CPU 101 transmits a call prohibition notification indicating that transmission (call) is prohibited to the requesting settlement apparatus 20. Also good.

  The CPU 101 generates information for specifying unsettled call transaction information. For example, when the transaction information is transmitted to the settlement apparatus 20, the CPU 101 generates unsettled call data (also referred to as allocated information) including a transaction number for identifying the transaction information. The unsettled call data is held (stored) in the unsettled call file.

  The CPU 101 deletes (deletes) the unsettled call data held in the unsettled call file. For example, when the CPU 101 obtains a settlement completion notification indicating that the settlement process has been completed from the settlement apparatus 20 (or the store controller 30) via the communication unit 109, the CPU 101 obtains the transaction number included in the settlement completion notification. Erase the unsettled recalled data, including the unsettled recalled file. In other words, the transaction information of the transaction number is not unsettled call transaction information. Specifically, the transaction information that has been settled is settled transaction information.

  Further, for example, the CPU 101 deletes the unsettled calling data from the unsettled calling file based on the operation of the clerk S. In other words, the transaction information is not unsettled call transaction information. Specifically, the transaction information that has not been processed (settlement processing) in the settlement apparatus 20 is unsettled uncalled transaction information that has not been transmitted to the settlement apparatus 20. That is, the prohibition of transmission to the settlement apparatus 20 is released based on the release operation of the clerk S.

  When the CPU 101 deletes the unsettled call data from the unsettled call file based on the operation of the store clerk S, the CPU 101 transmits a release notification indicating that the call prohibition has been released to the checkout device 20.

  FIG. 4A shows an example of an unsettled call file. In the unsettled call file in FIG. 4A, unsettled call data (A in the figure) including the transaction number “000066” is held. The register number is device identification information of the registration device 10 that has generated the unpaid call-up data, in other words, the registration device 10 that has executed the registration process. The bill number is medium identification information for identifying the bill issued in the transaction (registration process) identified by the transaction number in the unpaid call-up data. The settlement machine number is the device identification information of the settlement apparatus 20 that is the destination of transaction information, in other words, the settlement apparatus 20 that has read the bill. The unsettled call data may include person-in-charge identification information, date and time when the transaction information is transmitted, and the like.

  FIG. 4B is a diagram illustrating an example of the unsettled call list. The unsettled call data (A) of FIG. 4 (a) is displayed in the unsettled call list of FIG. 4 (b). The cancel button (B in the figure) cancels the prohibition of calling (transmission prohibition) to the settlement apparatus 20, that is, the transaction information corresponding to the unsettled called transaction information does not correspond to the unsettled called transaction information. It is a button for changing the state to transaction information. For example, when the clerk S touches and selects the unsettled call data in the unsettled call list, and then touches the release button, the CPU 101 reads the selected unsettled call data from the unsettled call file. to erase. Moreover, if it is deleted from the unsettled call file, it is also deleted from the unsettled call list. A number button (C in the figure) and a designation button (D in the figure) are buttons for designating the settlement apparatus 20. When the clerk S touches the designation button after touching the number button, the CPU 101 touches the unsettled call data (related to the designated checkout apparatus 20 in the unsettled call list) ( The settlement call data including the settlement machine number of the settlement apparatus 20 designated by the number button) may be highlighted, or only unsettled call data related to the designated settlement apparatus 20 may be displayed. Also good. Further, the unsettled call data related to the designated settlement apparatus 20 may be displayed together at the top of the unsettled call list. Note that FIGS. 4C and 4D will be described later.

  FIG. 5 is a diagram illustrating an example of a bill. The check ticket in FIG. 5 includes a transaction date and time (print date in the figure), a transaction number, a number (the number of purchases in the figure), a message, and a barcode in which the transaction number is converted into a one-dimensional barcode. , Is printed. When the registration device 10 prints and issues the accounting ticket shown in FIG. 5, the store clerk S hands the issued accounting ticket to the customer C, and the customer C prints the accounting ticket on any of the checkout devices 20. Have the barcode read.

  Next, the settlement apparatus 20 will be described. FIG. 6 is a block diagram illustrating a configuration example of the settlement apparatus 20 in the first embodiment (the same applies to the second embodiment (described later) and the third embodiment (described later)). As shown in FIG. 6, the settlement apparatus 20 includes a CPU 201, a ROM 202, a RAM 203, a scanner unit 204, a display operation unit 205, a communication unit 207, a buzzer 208, a printing unit 209, and a change machine 210. The bus 211 is provided. These are connected to each other via a bus 211.

  The CPU 201 controls the entire settlement apparatus 20 by developing a program stored in the ROM 202 in the RAM 203 and executing it. Details will be described later.

  The ROM 202 stores various information. For example, the ROM 202 stores a program executed by the CPU 201, a device number of the own device (device identification information), and the like.

  The RAM 203 temporarily stores various information. For example, the RAM 203 temporarily stores a program read from the ROM 202 and information (for example, transaction number and money information) acquired or generated by executing the program. The RAM 203 may temporarily store a product file.

  The scanner unit 204 optically reads a barcode printed on a check ticket issued by the registration apparatus 10 to obtain a transaction number (obtained by reversely converting the coded transaction number). The scanner unit 204 notifies the CPU 201 of the acquired transaction number.

  The display operation unit 205 is, for example, a liquid crystal touch display device capable of displaying information on the customer C and accepting the operation of the customer C. Information displayed on the display operation unit 205 includes, for example, a menu screen, various GUI operation buttons, processing information for registration processing (for example, the product name, number of purchases, sales price, total amount of purchased products), monetary information (deposited) Money information, change information) and various messages. When there is an operation of the customer C in the display operation unit 205, an operation signal is notified to the CPU 201. The GUI operation buttons include, for example, a start button for starting the checkout process, a confirmation button for inputting a confirmation intention, and the like.

  The communication unit 207 is a communication interface for communicating with an external device via the LAN 40. The buzzer 208 is a sound generator for generating a confirmation sound and a warning sound. The printing unit 209 prints on a medium and issues it. For example, the printing unit 209 prints a receipt printed with person-in-charge identification information, transaction date and time, transaction number, product name, number of purchases for each product, amount for each product, total amount, deposit amount, store name, and the like.

  The change machine 210 includes a coin inlet and outlet. The change machine 210 counts money (also referred to as deposit amount) inserted into the insertion slot by the customer C and notifies the CPU 201 of the deposit information. Further, the change machine 210 discharges the change from the discharge port based on the change information notified from the CPU 201.

  The CPU 201 acquires the transaction number transmitted from the registration device 10 via the communication unit 207. The CPU 201 temporarily stores the acquired transaction number in the RAM 203.

  When the CPU 201 obtains the transaction number via the scanner unit 204 (when the barcode printed on the bill issued by the registration device 10 is read by the scanner unit 204), the CPU 201 issues the bill. The transaction information is requested to the registration device 10 (the registration device 10 that has executed the registration process). Specifically, the CPU 201 transmits request information including a transaction number obtained from the barcode to the registration device 10 via the communication unit 207.

  In addition, although it demonstrated that the transaction number may be the structure containing the apparatus number of the registration apparatus 10, when setting it as the transaction number which does not include an apparatus number, CPU201 inquires the store computer 30 and the said transaction number The registration device 10 that has performed the registration process may be specified, and the request information may be transmitted to the specified registration device 10. Further, the CPU 201 may transmit the request information to all the registration devices 10 on the LAN 40. In the case of transmitting request information to all the registration devices 10, each registration device 10 determines whether or not the transaction information registered in its own device is requested based on the transaction number included in the request information. If requested, the transaction information is transmitted to the settlement apparatus 20, and if not requested, the request information may be ignored.

  CPU201 acquires the transaction information received from the registration apparatus 10 after a request | requirement, and performs a payment process using the acquired transaction information. For example, the CPU 201 calculates the change amount based on the total amount and the deposit amount indicated by the deposit information notified from the change machine 210, and notifies the change machine 210 of the change information indicating the calculated change amount, Necessary change is discharged to the change machine 210. The CPU 201 causes the display operation unit 205 to display a total amount, a change amount, a message, and the like according to the progress of the settlement process.

  When the settlement process is completed, the CPU 201 controls the communication unit 207 to transmit settlement information (for example, date and time, deposit amount, change amount) of the settlement process to the store controller 30. In addition, when the settlement process is completed, the CPU 201 controls the communication unit 207 to transmit a settlement completion notification indicating that the settlement process has been completed to the registration apparatus 10 that has issued the bill. Further, the CPU 201 controls the printing unit 209 to issue a receipt (not shown).

  FIG. 7 is a flowchart showing an operation flow of the settlement apparatus 20. The flowchart of FIG. 7 is always started while the settlement apparatus 20 is activated. Each step is controlled by the CPU 201.

Step S1: It is determined whether or not the bar code of the bill is read. That is, the CPU 201 determines whether or not the barcode printed on the bill (FIG. 5) issued by the registration device 10 has been read by the scanner unit 204. When it is determined that it has been read (step S1; Yes), the process proceeds to step S2. When it is determined that it has not been read (step S1; No), the flowchart of FIG. 7 ends.

Step S2: Request transaction information from the registration device 10. Specifically, the CPU 201 transmits request information including a transaction number obtained from the barcode to the registration device 10 that has executed the registration process.
Step S3: It is determined whether or not transaction information has been received from the registration device 10 as a response to the request in Step S2. When it is determined that it has been received (step S3; Yes), the process proceeds to step S4. When it is determined that the data has not been received (step S3; No), the process proceeds to step S6. The CPU 201 determines that the transaction information has not been received when the transaction information has not been received within a predetermined time after the request information has been transmitted, or when the call prohibition notification has been received.

  In addition, when transaction information is received from the registration apparatus 10 (step S3; Yes), that is, when the registration apparatus 10 transmits transaction information, the transaction information becomes unsettled call transaction information. More specifically, the registration device 10 that has transmitted the transaction information generates unsettled call data including a transaction number (a transaction number included in the request information) for identifying the transaction information, and the unsettled call To the finished file. Thereby, calling of the transaction information is set to be prohibited.

Step S4: Following the step S3, a settlement process is executed. Specifically, the CPU 201 executes the settlement process using the transaction information received from the registration device 10. In addition, the CPU 201 issues a receipt and transmits settlement information to the store controller 30.

Step S5: Subsequent to step S4, a payment completion notice indicating that the payment process has been completed is transmitted to the registration apparatus 10 that issued the bill, that is, the registration apparatus 10 that has executed the registration process for the transaction. Then, the flowchart of FIG. 7 ends.

  When the settlement completion notification is transmitted to the registration device 10 (step S5), that is, when the registration device 10 receives the settlement completion notification, the transaction information is not the unsettled call transaction information (the settlement transaction). Information). More specifically, the registration device 10 that has received the settlement completion notification deletes the unsettled call data including the transaction number included in the settlement completion notification from the unsettled call file.

Step S6: It is determined whether or not there is a release (step S6). When it is determined that there is a release (step S6; Yes), the process proceeds to step S7. When it is determined that there has been no cancellation (step S6; No), the flowchart of FIG. 7 ends. Note that the CPU 201 determines that there has been a release when receiving a release notification from the registration device 10.
Step S7: A message is displayed. For example, a message for reading the barcode is displayed again. Then, the flowchart of FIG. 7 ends.

  As described above, in the POS system 1, when the settlement apparatus 20 reads a transaction number of a certain transaction from the check ticket, it requests the registration apparatus 10 for transaction information of the transaction. The registration device 10 transmits (supplies) the transaction information of the transaction in response to the request, and adds the unsettled call data of the transaction to the unsettled called file, thereby transmitting (supplying) the transaction information. ) Is prohibited. Subsequently, the settlement apparatus 20 executes a settlement process for the transaction, and transmits a settlement completion notification for the transaction to the registration apparatus 10 when the settlement process is completed. Upon receiving the settlement completion notification, the registration device 10 deletes the unsettled call data of the transaction from the unsettled call file. That is, the registration device 10 cancels the prohibition on transmission (supply) of transaction information of the transaction. The registration device 10 also deletes the unsettled call data from the unsettled call file even when the store clerk S performs a canceling operation before receiving the settlement completion notification.

  In the above description, the transaction information is supplied using the bill printed with the one-dimensional barcode. However, as described above, the transaction information is supplied using the bill printed with the two-dimensional code. Alternatively, the clerk S may supply the transaction information by designating the settlement apparatus 20 via the clerk operation unit 108 or the like without using the bill. Hereinafter, instead of an aspect using a check ticket printed with a one-dimensional barcode (hereinafter also referred to as aspect A), an aspect using a check ticket printed with a two-dimensional code (hereinafter also referred to as aspect B), or a settlement apparatus A description will be given of prohibition and cancellation of transmission (supply) of transaction information and the like in an aspect in which 20 is specified (that is, an aspect in which transaction information is allocated; hereinafter also referred to as aspect C). In aspect C, it is arranged on a display screen different from the unsettled call list shown in FIG. 4B, for example, a product registration screen (not shown) displayed during the execution of the registration process. The settlement apparatus 20 may be designated using the number button and the designation button.

  In addition, the aspect C can be classified into some according to the timing to prohibit and the content to prohibit. Here are some examples. The first is a mode (hereinafter also referred to as mode C1) in which transaction information is transmitted (supplied) and subsequent transaction information is transmitted (supplied) when the settlement apparatus 20 is designated. Second, when the settlement apparatus 20 is designated, the transaction information is transmitted (supplied) and the designation of the settlement apparatus 20 related to the transaction (assignment of transaction information of the transaction) is prohibited (hereinafter referred to as “transaction information”). Also referred to as aspect C2.) Third, when the settlement apparatus 20 is designated, the transaction number is transmitted to the designated settlement apparatus 20, and then the transaction information is transmitted (supplied) to the settlement apparatus 20 in response to a request from the settlement apparatus 20 ), The transmission (supply) of subsequent transaction information is prohibited (hereinafter also referred to as aspect C3). The fourth mode is a mode (hereinafter also referred to as mode C4) in which when the settlement apparatus 20 is designated, the transaction number is transmitted to the designated settlement apparatus 20 and the subsequent transmission of the transaction number is prohibited. Fifth, when the settlement apparatus 20 is designated, the transaction number is transmitted to the designated settlement apparatus 20 and the designation of the settlement apparatus 20 regarding the transaction (assignment of transaction information of the transaction) is prohibited. This is an aspect (hereinafter also referred to as aspect C5). Sixth, when the settlement apparatus 20 is designated, the transaction number is transmitted to the designated settlement apparatus 20 and the transaction information is transmitted (supplied) to other settlement apparatuses 20 other than the settlement apparatus 20 thereafter. Is an aspect (hereinafter also referred to as aspect C6).

(Prohibition and cancellation of transaction information acquisition in Aspect B)
The checkout device 20 obtains transaction information from the two-dimensional code printed on the bill issued by the registration device 10 and also obtains the transaction number of the transaction (the transaction number included in the transaction information is registered in the registration device 10 ( For example, the registration device 10 that has issued the bills determines whether the unsettled call data of the transaction number received from the checkout device 20 exists in the unsettled call file. When the unsettled call data of the received transaction number does not exist in the unsettled call file, the registration device 10 responds to the settlement device 20 with information indicating that it does not exist (not prohibited). , By adding the unsettled call data of the received transaction number to the unsettled called file, it is possible to obtain the transaction information from the bill of interest (to the checkout device 20) (Provision of transaction information), and reissue of transaction vouchers (transaction vouchers printed with a 2D code obtained by converting the transaction information of the transaction into a 2D code) (transaction information to the checkout device 20) On the other hand, when the unsettled call data of the received transaction number exists in the unsettled call file, the registration device 10 sets the information indicating that it exists (prohibited) to the checkout device. The settlement apparatus 20 executes the settlement process using the transaction information acquired from the bill when the information indicating that it does not exist (not prohibited) is received from the registration apparatus 10. When the settlement apparatus 20 receives information indicating that it exists (prohibited) from the registration apparatus 10 (that is, when transaction information has already been acquired from the bill), the settlement process is performed. Do not execute. In addition, the registration device 10 deletes the unsettled call data of the transaction from the unsettled call file when receiving the settlement completion notification of the transaction from the settlement device 20. Also, the registration device 10 Even if there is a cancellation operation before receiving the settlement completion notification, the unsettled call data of the transaction will be deleted from the unsettled call file, so that transaction information can be obtained from the bill. The prohibition and the prohibition on reissuing the bill are canceled (the prohibition on the supply of the transaction information to the settlement apparatus 20 is canceled).

(Prohibition and cancellation of transaction information transmission in aspect C1)
The registration device 10 transmits the transaction information of the transaction to the designated settlement device 20, and adds the unsettled call data of the transaction to the unsettled call file, thereby transmitting (supplying) the transaction information thereafter. ) Is prohibited. For example, when there is an operation for instructing transmission (retransmission) of transaction information, the registration device 10 does not immediately transmit (retransmit) the transaction information, but instead transmits the transaction number of the transaction information (to the transaction information). It is determined whether the unsettled call data of the transaction number included in the unsettled call file exists, and when the unsettled call data of the transaction number of the transaction information does not exist in the unsettled call file, The transaction information is transmitted to the specified settlement apparatus 20, and the unsettled call data of the transaction number is added to the unsettled call file, and the unsettled call data of the transaction number of the transaction information is unsettled If it exists in the file, transmission (retransmission) should not be performed. The same applies to each prohibition such as prohibition of designation of the settlement apparatus 20 and prohibition of transmission of transaction information in modes C2 to C6 described later. On the other hand, the settlement apparatus 20 that has received the transaction information executes a settlement process using the transaction information when, for example, a predetermined operation is performed. Moreover, when the registration apparatus 10 receives the settlement completion notification of the transaction from the settlement apparatus 20, the registration apparatus 10 deletes the unsettled call data of the transaction from the unsettled call file. Also, the registration device 10 deletes the unsettled call data of the transaction from the unsettled call file even if there is a canceling operation for the transaction before receiving the settlement completion notification. Thereby, the prohibition of transmission (supply) of transaction information is lifted.

(Prohibition and cancellation of designation of the settlement apparatus 20 in the mode C2)
The registration device 10 transmits the transaction information of the transaction to the specified settlement device 20 and adds the unsettled call data of the transaction to the unsettled call file, thereby the settlement device 20 of the settlement device 20 regarding the subsequent transaction. Designation (subsequent allocation of transaction information of the transaction) is prohibited. In other words, since the settlement apparatus 20 cannot receive the transaction information unless specified, the subsequent transmission (supply) of the transaction information is prohibited by prohibiting the subsequent designation of the settlement apparatus 20. On the other hand, the settlement apparatus 20 that has received the transaction information executes a settlement process using the transaction information when, for example, a predetermined operation is performed. Moreover, when the registration apparatus 10 receives the settlement completion notification of the transaction from the settlement apparatus 20, the registration apparatus 10 deletes the unsettled call data of the transaction from the unsettled call file. Also, the registration device 10 deletes the unsettled call data of the transaction from the unsettled call file even if there is a canceling operation for the transaction before receiving the settlement completion notification. Thereby, the prohibition of designation of the settlement apparatus 20 (prohibition of allocation of transaction information) is lifted.

(Prohibition and cancellation of transaction information transmission in aspect C3)
The registration apparatus 10 transmits the transaction number of the transaction to the designated settlement apparatus 20. The settlement apparatus 20 that has received the transaction number requests the transaction information of the transaction from the registration apparatus 10 when a predetermined operation is performed, for example. The following flow is the same as the flow when using a bill. That is, when the registration device 10 transmits (supplies) transaction information of a transaction in the settlement device 20, the registration device 10 transmits the transaction information later by adding the unsettled call data of the transaction to the unsettled call file. (Supply) is prohibited, and when the settlement completion notification of the transaction is received from the settlement apparatus 20, the unsettled call data of the transaction is deleted from the unsettled call file. Also, the registration device 10 deletes the unsettled call data of the transaction from the unsettled call file even if there is a canceling operation for the transaction before receiving the settlement completion notification. Thereby, the prohibition of transmission (supply) of transaction information is lifted.

  FIG. 4C is a diagram illustrating an example of an unsettled call file in the aspect C3. When the transaction information is transmitted (supplied) in response to a request from the settlement apparatus 20 that has transmitted the transaction number, the registration apparatus 10 generates unsettled call data as shown in FIG. To the finished file. In the unsettled call file in FIG. 4C, unsettled call data (E in the figure) including the transaction number “000066” is held. The cash register number is device identification information of the registration device 10. The settlement machine number is device identification information of the settlement device 20 that is a transmission destination (supply destination) of transaction information. The unsettled call data may include the person-in-charge identification information, the date and time when the transaction information is transmitted (supplied), and the like. Further, items corresponding to the items of the unsettled called file in FIG. 4C are displayed in the unsettled called list.

(Prohibition and cancellation of transaction number transmission in Aspect C4)
The registration device 10 transmits the transaction number of the transaction to the specified settlement device 20 and prohibits subsequent transmission of the transaction number by adding the unsettled call data of the transaction to the unsettled call file. To do. That is, since the settlement apparatus 20 cannot receive the transaction information unless it receives the transaction number, the transmission (supply) of the subsequent transaction information is prohibited by prohibiting the transmission of the subsequent transaction number. On the other hand, the settlement apparatus 20 that has received the transaction number requests the transaction information of the transaction number from the registration apparatus 10 when a predetermined operation is performed, for example, and performs the settlement process using the received transaction information in response to the request. Run. Further, the registration device 10 deletes the unsettled call-up data from the unsettled call-up file when the settlement completion notification is received or when there is a release operation before receiving the settlement completion notification. Thereby, prohibition of transmission of a transaction number is cancelled | released.

  FIG. 4D shows an example of an unsettled call file in mode C4. When the transaction number is transmitted, the registration device 10 generates unsettled call data as shown in FIG. 4D and adds it to the unsettled call file. In the unsettled call file in FIG. 4D, unsettled call data (F in the figure) including the transaction number “000066” is held. In the unsettled call file in FIG. 4D, the settlement machine number is device identification information of the designated settlement device 20. The designated time is the date and time when the settlement apparatus 20 is designated. The unsettled call data may include person-in-charge identification information.

(Prohibition and cancellation of the setting of the settlement apparatus 20 in the aspect C5)
The registration apparatus 10 transmits the transaction number of the transaction to the specified settlement apparatus 20, and adds the unsettled call data of the transaction to the unsettled call file, thereby adjusting the settlement apparatus 20 for the subsequent transaction. Designation (subsequent allocation of transaction information of the transaction) is prohibited. In other words, since the settlement apparatus 20 cannot receive the transaction information unless specified, the subsequent transmission (supply) of the transaction information is prohibited by prohibiting the subsequent designation of the settlement apparatus 20. On the other hand, the settlement apparatus 20 that has received the transaction number requests the transaction information of the transaction number from the registration apparatus 10 when a predetermined operation is performed, for example, and performs the settlement process using the received transaction information in response to the request. Run. Further, the registration device 10 deletes the unsettled call-up data from the unsettled call-up file when the settlement completion notification is received or when there is a release operation before receiving the settlement completion notification. Thereby, the prohibition of designation of the settlement apparatus 20 (prohibition of allocation of transaction information) is lifted.

(Prohibition and cancellation of transaction information transmission in aspect C6)
The registration device 10 transmits the transaction number of the transaction to the designated settlement device 20, and if there is no unsettled call data of the transaction in the unsettled call file, the unsettled call of the transaction The transaction data is prohibited from being transmitted (supplied) to another settlement device 20 by adding the completed data to the unsettled call file. In other words, even when the registration apparatus 10 transmits a transaction number to a certain settlement apparatus 20, the registration apparatus 10 already has unsettled call data for the transaction in the unsettled call file (other settlements). If the transaction number has already been transmitted to the device 20, the unsettled call data relating to the transmission of the transaction number is not added to the unsettled call file. Further, when the transaction information of the transaction number is requested from the settlement device 20 that is the transmission destination of the transaction number, the registration device 10 has the transaction number and the unsettled call data of the settlement device 20 exists. When the transaction number is first transmitted to the settlement apparatus 20, the transaction information is transmitted (supplied) to the settlement apparatus 20. In other words, the transmission (supply) of transaction information to other settlement apparatuses 20 other than the settlement apparatus 20 specified first is prohibited. The settlement apparatus 20 that first receives the transaction information transmits a settlement completion notification to the registration apparatus 10 after the settlement process is completed. The registration device 10 deletes the unsettled call data from the unsettled call file when the settlement completion notification is received or when a cancel operation is performed before the settlement completion notification is received.

  FIG. 8 is a flowchart showing an operation flow of the registration apparatus 10. Specifically, it is a flowchart showing the flow of operation of the registration apparatus 10 in a mode in which transmission of a subsequent transaction number or the like is prohibited when the settlement apparatus 20 is designated. The flowchart of FIG. 8 is always started while the registration apparatus 10 is activated. Each step is controlled by the CPU 101.

Step S10: It is determined whether or not a release operation by the clerk S has been performed. The CPU 101 determines that there has been a release operation when an operation signal such as pressing the release button is notified, and determines that there is no operation signal when the operation signal is not notified. When it is determined that there has been a release operation (step S10; Yes), the process proceeds to step S20. When it is determined that there is no release operation (step S10; No), the process proceeds to step S11.
Step S11: It is determined whether or not a settlement completion notification indicating that the settlement process has been completed is received from the settlement apparatus 20. When it is determined that it has been received (step S11; Yes), the process proceeds to step S19. When it is determined that the data has not been received (step S11; No), the process proceeds to step S12.

Step S12: It is determined whether or not transaction information is requested from the settlement apparatus 20, that is, whether or not the request information is received. When it is determined that it has been received (step S12; Yes), the process proceeds to step S16. When it is determined that the data has not been received (step S12; No), the process proceeds to step S13.

Step S13: A registration process is executed. That is, the CPU 101 registers the purchased product of the customer C by reading with the scanner unit 104 or pressing a preset button. Further, the CPU 101 generates transaction information after completing the registration process, temporarily stores the generated transaction information in the RAM 103, and transmits the transaction information of the transaction to the store controller 30. If the registration process is not required, such as when there is no customer C, the registration process is not executed and the flowchart of FIG. 8 ends.

Step S14: The transaction number is transmitted to the settlement apparatus 20. That is, the CPU 101 transmits the transaction number included in the transaction information of the transaction to the settlement apparatus 20 designated by the store clerk S.
Step S15: The unsettled call data of the transaction is added to the unsettled call file. Thus, for example, in the case of the mode C4, transmission of the subsequent transaction number is prohibited, in the case of the mode C5, the designation of the subsequent settlement apparatus 20 is prohibited, and in the case of the mode C6, the subsequent settlement apparatus 20 concerned. Transmission of transaction information to other settlement apparatuses 20 other than the above is prohibited. Then, the flowchart of FIG. 8 ends.

Step S16: The registration apparatus 10 that has received the request information from the settlement apparatus 20 determines whether or not the requested transaction information is prohibited from being called. That is, the CPU 101 determines whether or not the transaction information identified by the transaction number included in the request information corresponds to unsettled call transaction information. More specifically, the CPU 101 determines whether the unsettled call data for the transaction number is stored in the unsettled call file. When it is determined that the calling is prohibited (step S16; Yes), the process proceeds to step S18. When it is determined that the calling is not prohibited (step S16; No), the process proceeds to step S17.
Step S17: The transaction information is transmitted to the requesting settlement apparatus 20. That is, when the requested transaction information does not correspond to the unsettled call transaction information, the CPU 101 acquires the transaction information from the RAM 103 and transmits it to the requesting settlement apparatus 20. Then, the flowchart of FIG. 8 ends.
Step S18: A call prohibition notice is transmitted to the requesting settlement apparatus 20. That is, when the requested transaction information corresponds to the unsettled call completed transaction information, the CPU 101 transmits a call prohibition notification to the requesting settlement apparatus 20 without transmitting the transaction information. Then, the flowchart of FIG. 8 ends.

Step S19: Upon receiving the settlement completion notification from the settlement apparatus 20, the registration apparatus 10 deletes the unsettled call data held in the unsettled call file. That is, the CPU 101 deletes the unsettled call data including the transaction number included in the settlement completion notification from the unsettled call file. Then, the flowchart of FIG. 8 ends.
Step S20: If there is a canceling operation by the store clerk S, the registration device 10 erases the unsettled call data held in the unsettled call file. That is, the CPU 101 erases the unsettled call data including the transaction number selected in the cancel operation from the unsettled call file. Thereby, prohibition of subsequent transmission of the transaction information of the transaction is lifted.
Step S20: A cancellation notification indicating that the calling prohibition has been canceled is transmitted to the settlement apparatus 20. Then, the flowchart of FIG. 8 ends.

  As described above, according to the POS system 1 in the first embodiment, even if the supply of transaction information is prohibited, it can be supplied again if it is canceled (Aspect A, Aspect B, Aspect C1, Aspect C3, Aspect C4, Aspect C6). Moreover, even if it is a case where allocation of transaction information is prohibited, if it cancels | releases, allocation can be performed again (mode C2, mode C5). Therefore, even when the power of the settlement apparatus 20 is turned off during the settlement process, the settlement process can be resumed quickly without taking time and effort. That is, the settlement process can be resumed with a simple mechanism of adding and deleting unsettled call-up data.

  Moreover, the registration apparatus 10 makes the salesclerk S select whether to perform cancellation | release. Specifically, after the clerk S selects a certain unsettled call data in the unsettled call list, the unsettled call data is actually called the unsettled call according to whether or not the release button is touched. Whether or not to delete from a completed file. That is, as shown in FIG. 4, the registration device 10 displays a list of unpaid calls (transaction information of unpaid transactions, and can identify transaction information for which supply or allocation is prohibited thereafter) And the prohibition of the subsequent supply or allocation of the transaction information specified in the unpaid call-out list is lifted. In addition to the cancel button for inputting an intention to cancel, a cancel button for inputting an intention not to cancel may be arranged. Further, after touching the release button, a small screen on which a YES button and a NO button for confirming the final intention may be displayed.

  In the unsettled call list, unsettled call data registered in a plurality of registration devices 10 may be displayed. For example, in addition to the unsettled call file held by the self-registration device 10, the unsettled call file held by the other registration device 10 is also referred to, and the unsettled call data of other registration devices 10 in the unsettled call list May be displayed. When displaying the unsettled call data registered in a plurality of registration devices 10 in the unsettled call list, the registration device 10 can be designated using the unsettled call list designation button. Even if the unsettled call data related to the designated registration device 10 (settlement call data including the registration number of the registration device 10 designated by the number button) is highlighted in the unsettled call list. Alternatively, only unsettled and called data related to the designated registration device 10 may be displayed. Further, the unsettled call data related to the designated registration device 10 may be displayed together at the top of the unsettled call list.

  In addition to the registration device 10, the settlement device 20, the store controller 30, and the monitoring device 31 (not shown) refer to the unsettled call file stored in each registration device 10, and display the unsettled call list. It may be displayed. Further, one representative registration device 10 acquires unsettled call data (or original data for generating unsettled call data) from each registration device 10 and holds an unsettled call file. May be. Further, in addition to the registration device 10, each settlement device 20 (or one representative settlement device 20) may hold an unsettled call file, and the store controller 30 holds an unsettled call file. Alternatively, the monitoring device 31 (not shown) may hold an unsettled call file.

  As an example, a mode (mode A) using a check ticket printed with a one-dimensional barcode when the store controller 30 holds an unsettled call file will be described. The settlement apparatus 20 transmits (notifies) the transaction number to the store controller 30 when acquiring the transaction number from the one-dimensional barcode printed on the check ticket issued by the registration apparatus 10. The store controller 30 that has received the transaction number determines whether or not unsettled call data for the transaction number exists in the unsettled call file. When the store controller 30 determines that the unsettled call data for the transaction number does not exist in the unsettled call file, the store controller 30 sends a notification to that effect to the checkout device 20 and the unsettled call data for the transaction number. To the unsettled call file. When the store controller 30 determines that the unsettled call data for the transaction number exists in the unsettled call file, the store controller 30 transmits a notification to that effect to the checkout apparatus 20. On the other hand, when the settlement apparatus 20 receives a notification that the unsettled call data for the transaction number does not exist in the unsettled call file, the settlement apparatus 20 requests the registration information for the transaction number of the transaction number, The settlement process is executed using the transaction information received from. Further, the settlement apparatus 20 does not request the transaction information of the transaction number from the registration apparatus 10 when receiving the notification that the unsettled call data of the transaction number exists in the unsettled call file (that is, settlement) Do not perform processing).

  The same applies to an aspect (aspect B) that uses a bill printed with a two-dimensional code and an aspect (aspect C) that specifies the settlement apparatus 20. For example, in the aspect (Aspect C) in which the settlement apparatus 20 is designated, when a designation operation is performed in the registration apparatus 10 or the settlement apparatus 20 itself, an apparatus (the settlement apparatus 20, the store controller 30, It is determined whether or not the unsettled call data of the transaction exists in the unsettled call file of the monitoring device 31), and if it is determined that it does not exist, the process proceeds (for example, transaction information to the designated destination, or (Transaction number is transmitted) and unsettled call data of the transaction is added to the unsettled called file, and if it is determined that it already exists, the process may be stopped.

[Second Embodiment]
Next, a second embodiment of the present invention will be described in detail with reference to the drawings. The state that the POS system 2 in the second embodiment is operating is the same as the POS system 1 in the first embodiment shown in FIG.

Further, the store controller 30 stores the payment machine number “8” and the bill number “012” received from the payment apparatus 20-2. In other words, the store controller 30 rewrites the settlement machine number included in the information B (the settlement machine number “7” → the settlement machine number “8”). Further, the store controller 30 transmits information A (registration number “1”, check ticket number “012”) to the settlement apparatus 20-2. The settlement apparatus 20-2 stores information A as information D.
FIG. 13D: As in FIG. 9D, when the settlement process is completed in the settlement apparatus 20-2, information C (account number “012”, settlement is sent from the settlement apparatus 20-1 to the store controller 30. The date and time “○ month ○ day × hour × minute × second”) is transmitted. The store controller 30 stores information C. Further, the settlement apparatus 20-2 deletes the information D because the settlement process has been completed.

  FIG. 14 is a flowchart showing an operation flow of the store controller 30 (or the monitoring device 41) in the POS system 2. The flowchart of FIG. 14 starts when a certain settlement apparatus 20 (referred to as settlement apparatus A) reads a certain bill (referred to as bill v).

Step S30: Information (information B) based on the reading of a certain check ticket (check ticket a) is received from a certain checkout device 20 (checkout device A).
Step S31: It is determined whether the bill a has already been read. That is, before the start of this flowchart, it is determined whether or not the bill a is read in the billing device A (or the billing device 20 other than the billing device A) (that is, the bills a after the second time). Whether or not it is read). Specifically, if the information (information B) based on the reading of the check ticket a is stored, it is determined that the check ticket a is read, and the information (information B) based on the reading of the check ticket a. If is not stored, it is determined that the bill a is not read. If the bill a is not read, the process proceeds to step S32. On the other hand, when the bill v is read, the process proceeds to step S40.
Step S32: As shown in FIG. 9 (c), information (information B) based on the reading of the bill a by the settlement apparatus A is stored.
Step S33: As shown in FIGS. 9C and 9D, information (information A) based on the issuance of the bill v is transmitted to the settlement apparatus A, and the settlement apparatus A is executed for the settlement process. In other words, the settlement apparatus A receives the information (information A) based on the issuance of the bill a from the store controller 30 (or the monitoring apparatus 41) and executes the settlement process. Then, the flowchart of FIG. 14 ends.

Step S40: It is determined whether or not the settlement process using the bill a has already been completed. Specifically, if the information (information C) based on the completion of the settlement process using the bill a is stored, it is determined that the settlement process using the bill a is completed, and the settlement process using the bill a. If the information (information C) based on the completion of is not stored, it is determined that the settlement process using the bill v is not completed. If the checkout process using the bill v has been completed, the process proceeds to step S41. On the other hand, if the checkout process using the bill a is not completed, the process proceeds to step S42.
Step S41: As shown in FIG. 10C, an error message (settled) is transmitted to the settlement apparatus A, and the settlement process by the settlement apparatus A is prohibited.

Step S42: As shown in FIG. 11 (a), the settlement apparatus 20 (the settlement apparatus 20 other than the settlement apparatus A or the settlement apparatus A) that has read the bill a first is information based on the issuance of the bill a. It is determined whether (information D) is stored. In addition, the payment apparatus 20 which read the check ticket a first can specify from the information (information B: check machine number, check ticket number) based on the reading of the check ticket. If information (information D) based on the issuance of the bill v is stored, the process proceeds to step S43. On the other hand, if the information (information D) based on the issuance of the bill a is not stored, the process proceeds to step S44.
Step S43: As shown in FIG. 11 (e), an error message (read twice) is transmitted to the settlement apparatus A, and the settlement process by the settlement apparatus A is prohibited.

Step S44: As shown in FIG. 13 (c), the bill received from the settlement device (the settlement device 20 other than the settlement device A or the settlement device A) that has previously read the bill a is stored. The information (information B) based on the reading of a is deleted. In addition, this time, information (information B) based on the reading of the bill a received from the settlement apparatus A is stored.
Step S45: As shown in FIGS. 13C and 13D, information (information A) based on the issuance of the bill v is transmitted to the settlement apparatus A, and the settlement apparatus A is executed for the settlement process. In other words, the settlement apparatus A receives the information (information A) based on the issuance of the bill a from the store controller 30 (or the monitoring apparatus 41) and executes the settlement process. Then, the flowchart of FIG. 14 ends.

  As described above, according to the POS system 2 in the second embodiment, similarly to the POS system 1 in the first embodiment, even if the supply of transaction information is prohibited, if the release is performed, the transaction information is supplied again. be able to. In addition, the prohibition can be canceled based on whether or not the information B, the information C, and the information D (information A) are stored even if the store clerk is not designated. Although described with reference to the flowchart of FIG. 14, the monitoring device 31 may execute the processes shown in FIGS. 9 to 13 instead of the store controller 30.

[Third Embodiment]
Next, a third embodiment of the present invention will be described in detail with reference to the drawings. The state in which the POS system 3 in the third embodiment is operating is the same as the POS system 1 in the first embodiment shown in FIG. The configuration example of the registration device in the third embodiment is the same as the configuration example of the registration device 10 of the POS system 1 shown in FIG. Further, the configuration example of the settlement apparatus in the third embodiment is the same as the configuration example of the settlement apparatus 20 of the POS system 1 shown in FIG.

  15 to 18 are explanatory diagrams for explaining the POS system 3. Specifically, FIG. 15 is a flowchart for explaining an operation flow when the power of the settlement apparatus 20 is turned off after the transaction information is received (the power is turned off by a first power-off operation described later). The left side of FIG. 15 (steps S50 to S56) represents an operation after registration processing in a certain registration device 10 (for example, the registration device 10-1). The right side of FIG. 15 (steps S60 to S67) represents an operation after receiving transaction information in a certain settlement apparatus 20 (for example, settlement apparatus 20-1).

  FIG. 16A is a display example during registration processing on the product registration screen. FIG. 16B is a display example after designation of the settlement apparatus 20 on the product registration screen. FIG. 17A is a display example after receiving a call back confirmation request (described later) on the product registration screen. FIG. 17B is a display example of an unsettled list screen (screen for displaying an unsettled call list). FIG. 18A is a display example of a confirmation screen displayed after a “call back” button (described later) is pressed. 18B and 18C are display examples of journal information (settlement information, processing history information).

Step S50: The registration device 10-1 accepts an operation of a call by the clerk S (specifically, designation of the payment device 20) after the registration process is completed. That is, the registration device 10-1 performs a registration process as shown in FIG. 16A, for example, and then, for example, displays a button (“ The press of the “accounting machine 1” button) is accepted. In FIG. 16B, the diagonal line display of the “accounting machine 1” button indicates that the “accounting machine 1” button has been pressed.
Step S51: The registration device 10-1 transmits the transaction information to the settlement device 20-1 according to the designation in Step S50.

Step S60: The payment apparatus 20-1 receives the transaction information.
Step S61: The settlement apparatus 20-1 that has received the transaction information displays a message that prompts settlement. For example, the settlement apparatus 20-1 may display on the display operation unit 205 a settlement method (a screen for selecting settlement with cash or settlement with a card) as an initial screen of the settlement process.

Step S62: The payment apparatus 20-1 receives (detects) a power OFF operation. Specifically, a power-off operation (in order to turn off the settlement apparatus 20-1 through execution of a predetermined termination process (various termination processes so as not to cause a failure in the settlement apparatus 20-1) ( Hereinafter, this is referred to as “first power-off operation”. An example of the first power-off operation is a slide operation of a slide-type power switch provided in the settlement apparatus 20-1.

  Note that at the time of the processing in step S62 (at the time when the first power-off operation is performed), it is assumed that the settlement processing of the transaction information received in step S60 has not been completed.

Step S63: The settlement apparatus 20-1 transmits a “call back confirmation request” to the registration apparatus 10-1 that is the transmission source of the transaction information. That is, the settlement apparatus 20-1 transmits a call back confirmation request to the registration apparatus 10-1 that is the transmission source of the transaction information, as one end process after the first power-off operation. The call back confirmation request is a request for confirming whether or not it is necessary to execute “call back processing (also simply referred to as“ call back ”)”. The call back process is a process for making unsettled call transaction information (unsettled transaction information after a call) into unsettled uncall transaction information (unsettled transaction information before a call). That is, when a call-back process is executed for certain unsettled called transaction information, the unsettled called transaction information becomes unsettled uncalled transaction information. In other words, the call-back process means that there has been no call that has already been made (supply or allocation of transaction information. That is, designation of the settlement device 20, transmission of transaction information, reading of a bill, etc.). It is a process to make. The call back confirmation request may include a transaction number.

Step S52: The registration device 10-1 receives the call back confirmation request. For convenience of explanation, the example in which the process of step S52 is executed following the process of step S51 is used. However, the registration device 10-1 immediately returns the transaction after transmitting the transaction information of a transaction. A confirmation request is not always received. That is, another transaction registration process or the like may be performed between the process of step S51 and the process of step S52.

Step S53: Receiving the call back confirmation request, the registration device 10-1 performs notification regarding the call back. For example, when the registration device 10-1 receives a call back confirmation request while displaying the product registration screen, the notification on the product registration screen as shown in FIG. May display a message “call required”.

  When the clerk S who sees the message “calling required” presses a button for displaying the unsettled list screen (“unsettled one” button in the figure), the registration device 10-1 An unsettled list screen as shown in FIG. 17B is displayed. As shown in FIG. 17B, in one area of the unsettled list screen (the left side area in the example of FIG. 17B), as in the unsettled called list (see FIG. 4), the unsettled called A list is displayed, and in the other area (the area on the right side in the example of FIG. 17B), detailed information on one unsettled call transaction information (unsettled transaction information after the call) in the unsettled call list ( Information on each registered product etc.) is displayed. Specifically, the area on the right side (detailed information area) includes selection (selection by the operation of the clerk S, automatic selection not by the operation of the clerk S) in the left area (region of the unpaid call list). The detailed information of the unpaid and called transaction information is displayed. In addition, a display (for example, the clerk who knows which is not yet settled call transaction information currently selected in the left area (unsettled call transaction information whose detailed information is displayed in the right area) is displayed (for example, (Highlighted). For example, when the unsettled call transaction information with the number “2” is currently selected, the number “2” may be highlighted as shown in FIG. 17B (FIG. 17B ), The hatched display of the number “2” is an example of a highlighted display indicating that the unpaid call-backed transaction information of the number “2” is currently selected). The same applies to FIG.

  It should be noted that the “not yet settled” button can be pressed at any time. However, if the corresponding information (unsettled call transaction information) does not exist, the corresponding information exists before the unsettled list screen is displayed, for example, by thinly displaying the “unsettled one” button. The store clerk S may be informed that he / she does not. In addition, when there is no corresponding information, for example, the “unsettled one” button may be displayed lightly so that the “unsettled one” button cannot be pressed (no response or error even if pressed). Sound may be displayed).

  Also, the “call back” button on the unpaid list screen shown in FIG. 17B is a button to be pressed when executing the call back process. When the “call back” button is pressed, the registration apparatus 10-1 displays the unsettled call transaction information selected in the left area of the unsettled list screen (that is, detailed information in the right side of the unsettled list screen). Call back processing is executed for the unpaid call transaction information) on which is displayed.

Step S64: The settlement apparatus 20-1 enters the power OFF state after executing the process of step S63 (after transmitting the call back confirmation request).
Step S65: The settlement apparatus 20-1 restarts (begins to restart).

Step S54: The registration device 10-1 executes a call back process on the unpaid call-up transaction information related to the call back confirmation request after the execution of the process of step S53 (after performing the notification about the call back). Specifically, the state in which the unsettled call transaction information related to the call back confirmation request is selected in the left area of the unsettled list screen (the unsettled price related to the call back confirmation request in the right area of the unsettled list screen) When the “call back” button is pressed in the state where the detailed information of the called transaction information is selected, the call back processing is executed for the unsettled called transaction information related to the call back confirmation request.

  The registration device 10-1 may execute the call back process immediately when the “call back” button is pressed. However, after the store clerk S reconfirms the execution of the call back process, the call back process is actually performed. May be executed. For example, when the “call back” button is pressed, the registration device 10-1 displays a confirmation screen as shown in FIG. 18B, and a predetermined operation (for example, “forced call” in the figure) is displayed on the confirmation screen. The call-back process may actually be executed when the “Return” button is pressed).

  In addition, when the call back process is executed, it has been explained that the unsettled call transaction information related to the call back confirmation request becomes the unsettled uncall transaction information, but as the display screen, the registration process is started from the unsettled transaction screen. You may make it switch to a subsequent product registration screen (for example, the product registration screen in the state of FIG. 15A). That is, when the call back process is executed, the call is released, and the display screen before the call may be automatically switched to.

Step S55: The registration device 10-1 receives a recall (re-designation) operation by the clerk S after executing the process of step S54 (after executing the call back process). For example, the registration device 10-1 may accept an operation of calling (specifically, specifying the settlement device 20), similarly to the process of step S50.
Step S56: The registration device 10-1 transmits the transaction information to the settlement device 20-1 in accordance with the designation in step S55, similarly to the processing in step S51.

Step S66: The restarting settlement apparatus 20-1 receives the transaction information.
Step S67: The settlement apparatus 20-1 that has received the transaction information displays a message for prompting settlement as in the process of Step S61. Thereafter, the settlement apparatus 20-1 performs a settlement process according to the operation of the customer C (not shown).

  As described above, according to the flowchart of FIG. 15, the call-back process can be quickly performed when the power is turned off.

  In addition, after the execution of the process of step S53 (after the notification regarding the call back is executed), when the “unsettled one” button is pressed, the unsettled list screen displayed after the “unsettled one” button is pressed. , A message for alerting the store clerk S may be displayed. For example, as shown in Fig. 17 (B), at the top of the area on the right side (detailed information area), "This is a transaction that has not been completed because the checkout machine has been turned off. For this reason, a confirmation screen will be displayed. May be displayed.

  In addition, when the “unsettled one” button is pressed after executing the process of step S53 (after the notification about the recall), the call back confirmation request is made in the left area (unsettled call list area). Such unsettled called transaction information (transaction information identified by the transaction number included in the call back confirmation request) is automatically selected, and the selected unsettled called transaction information (in the detailed information region) is selected ( An unsettled list screen on which detailed information of unsettled and called transaction information related to the call back confirmation request is initially displayed is displayed. As a result, after receiving the call back confirmation request, if the "unsettled one" button is pressed, detailed information on the unsettled called transaction information that is the target of the recall process in the area on the right side of the unsettled list screen immediately Can be confirmed.

  In addition, when the “unsettled one” button is pressed after executing the processing of step S53 (after performing the notification regarding the recall), the recall is performed in the left area (unsettled call list area). The unsettled call transaction information related to the confirmation request may be initially displayed so as to be distinguishable from others. For example, in the example shown in FIG. 17B, in the left area, there are other fields for unpaid call-up transaction information related to the call back confirmation request (un-paid-up call transaction information in the column “2” in the figure). It is displayed in a different display mode. As a result, after the call back confirmation request is received, if the “unsettled one” button is pressed, immediately, in the area on the left side of the unsettled list screen, which of the unsettled called transaction information is the target of the recall process. You can see if there is.

  As shown in FIG. 17B, in the area on the left side of the unsettled list screen (unsettled called list area), unsettled called transaction information is displayed in order from the top. As a result, the store clerk S can easily find desired unsettled and called transaction information. In other words, the call back process is executed regardless of the call back confirmation request when adding, changing, or canceling a product, reading a membership card, forgetting to use a gift certificate, etc. Changes, cancellations, reading membership cards, forgetting to use gift certificates, etc. are subject to the most recent (latest) transaction. That is, in general, recall processing for reasons such as adding, changing, or canceling a product, reading a membership card, forgetting to use a gift certificate, etc. is intended for unsettled call transaction information of the immediately preceding (latest) transaction. It is. Accordingly, as shown in FIG. 17B, if the unpaid call transaction information is displayed in order from the top in the area on the left side of the unpaid list screen, adding, changing, canceling, reading the membership card, Even if the call back process is executed due to reasons such as forgetting to use the ticket, which of the unsettled call transaction information is subject to the call back process in the area on the left side of the unsettled list screen You will immediately understand. Specifically, if the “unsettled one” button is pressed before the other registration process is completed, the unsettled called transaction information to be recalled will be displayed in the area on the left side of the unsettled list screen. Since it is displayed at the top, it is possible to immediately find unsettled and called transaction information to be subjected to the call back process.

  As described above, when the “unsettled one” button is pressed after receiving the call back confirmation request, the unsettled state related to the call back confirmation request in the left area (unsettled call list area). Called transaction information is automatically selected, and in the area on the right (detailed information area), an unsettled list screen that initially displays the detailed information of the unsettled called transaction information related to the callback confirmation request is displayed. Regardless of the request, when the “Unsettled 1” button is pressed (when the “Unsettled 1” button is pressed without receiving a call back confirmation request), the left area (Unsettled Called List List of unsettled transactions that automatically selects the previous (latest) unsettled call transaction information in the area) and initially displays the detailed information of the previous (latest) unsettled call transaction information in the right area (detailed information area) Display the screen. Therefore, for example, in order to execute the call back process for the reason for adding, changing, canceling the product, reading the membership card, forgetting to use the gift certificate, etc. for the immediately preceding transaction regardless of the call back confirmation request. ”Button is displayed, the top of the left area of the unsettled list screen displays the unsettled call transaction information that is the target of the call back process, and the right side of the unsettled list screen displays Detailed information of the unpaid call transaction information is displayed. As a result, even if call back processing is executed for reasons such as adding, changing, or canceling a product, reading a membership card, or forgetting to use a gift certificate, the call is immediately made in the area on the right side of the unpaid list screen. It is possible to confirm the detailed information of the unsettled call transaction information to be returned.

  If the registration device 10-1 receives a call back confirmation request while displaying the unsettled list screen, the registration device 10-1 receives a call back notification in the left area (unsettled call list area). Select the unsettled call transaction information related to the call back confirmation request, and the right side (detailed information area) of the selected unsettled call transaction information (unsettled call transaction information related to the call back confirmation request) Display detailed information. In other words, if a call back confirmation request is received while the unsettled list screen is displayed, the call back confirmation request is used instead of the unpaid call-up transaction information selected before receiving the call back confirmation request. The display content is switched to the state where the unpaid call-up transaction information related to is selected (the display content is switched so as to be in the same state as when the “unpaid one” button is pressed after receiving the call back confirmation request) .

  When the registration device 10-1 executes the call-back process, the registration device 10-1 stores the fact that the call-back process has been executed in the journal information, but the call-back process based on the call-back confirmation request (unsettled for the call-back confirmation request) Called transaction information call-back processing) and normal call-back processing not based on a call-back confirmation request (for example, adding, changing, canceling a product, reading a membership card, forgetting to use a gift certificate, etc.) (Return processing) may be distinguished and stored in the journal information. For example, when a normal call back process is executed, “call back” may be simply stored, and when a call back process based on a call back confirmation request is executed, “forced call back” may be stored. As a result, by referring to the journal information, it is possible to know whether the normal call back process has been executed or the call back process based on the call back confirmation request has been executed. FIG. 18B is a display example based on journal information of normal call back processing, and “call back” is displayed at the beginning as the process name. FIG. 18C is a display example based on the journal information of the call-back process based on the call-back confirmation request, and “forced call-back” is displayed at the beginning as the process name.

  FIG. 15 shows the operations of the settlement apparatus 20-1 and the registration apparatus 10-1 after receiving the first power-off operation in the settlement apparatus 20-1, but the settlement apparatus 20 performs the first power-off operation. Instead of, or in addition to, the reception of other power-off operations may be possible. For example, the settlement apparatus 20 performs a power-off operation for turning off the settlement apparatus 20 without executing a predetermined end process (that is, forcibly placing the settlement apparatus 20 in a power-off state). A power OFF operation (hereinafter referred to as “second power OFF operation”) may be accepted. An example of the second power OFF operation is a long press operation of a power button provided in the settlement apparatus 20-1.

  FIG. 19 is an explanatory diagram for explaining the POS system 3. Specifically, FIG. 19 is a flowchart for explaining an operation flow when the power of the settlement apparatus 20 is turned off after the transaction information is received (the power is turned off by the second power-off operation). The left side of FIG. 19 (steps S150 to S156) represents an operation after registration processing in a certain registration device 10 (for example, the registration device 10-1). The right side of FIG. 19 (steps S160 to S167) represents an operation after receiving transaction information in a certain settlement apparatus 20 (for example, settlement apparatus 20-1).

  In addition, since each process of step S150-step S156 in FIG. 19 is the same as each process of step S50-step S56 in FIG. 15, description of each process of step S150-step S156 is abbreviate | omitted. Further, since the processes in steps S160, S161, S166, and S167 in FIG. 19 are the same as the processes in steps S60, S61, S66, and S67 in FIG. 15, the processes in steps S160, S161, S166, and S167 are the same. Description is omitted.

Step S162: The payment apparatus 20-1 receives (detects) a second power-off operation. Note that at the time of the processing in step S162 (at the time when the second power-off operation is performed), it is assumed that the settlement processing of the transaction information received in step S160 has not been completed.

Step S163: The payment apparatus 20-1 is turned off. In other words, when the first power-off operation is performed, the call-back confirmation request is transmitted and then the power-off state is entered (see steps S62, S63, and S64 in FIG. 15), but when the second power-off operation is performed. Is turned off without sending a call back confirmation request.
Step S164: The payment apparatus 20-1 restarts (begins restarting).

Step S165: After restarting (or during restarting), the checkout apparatus 20-1 transmits a “call back confirmation request” to the registration apparatus 10-1 that is the transmission source of the transaction information. That is, the checkout device 20-1 issues a call back confirmation request to the registration device 10-1 that is the transmission source of the transaction information as one of the processes after restart (or during restart) after the second power-off operation. Send. Thereafter, the settlement apparatus 20-1 receives the transaction information (step S166), displays a message prompting settlement (step S67), and executes a settlement process in accordance with the operation of the customer C (not shown).

  As described above, according to the flowchart of FIG. 19, the call-back process can be quickly performed when the power is turned off.

  In the process of step S165 in the flowchart of FIG. 19, the settlement apparatus 20-1 confirms the presence / absence of transaction information (unsettled call transaction information) that is the target of the call back confirmation request and the destination of the call back confirmation request. An example of how to do this is as follows. Information (for example, transaction number, device identification information of the registration device 10 that has executed the registration process) that can specify unpaid-up call transaction information and the like in the store controller 30 and information (for example, transaction) By appropriately storing the number and the device identification information of the registration device 10 that has performed the registration process), after the restart (or during the restart), the store controller 30 or the like stores the device (the settlement device 20- The presence / absence of unsettled call transaction information according to 1) may be inquired.

  In the flowchart of FIG. 15 (flowchart of FIG. 19), the settlement apparatus 20-1 (same settlement apparatus 20-1 as the first call) that is the transmission source of the call back confirmation request is recalled (redesignated). However, the settlement apparatus 20-2 different from the settlement apparatus 20-1 that has transmitted the call-back confirmation request may be recalled (redesignated).

  Further, in the flowchart of FIG. 15 (flowchart of FIG. 19), the settlement apparatus 20-1 transmits a call back confirmation request, but a “call back request” may be transmitted instead of the call back confirmation request. The “call back request” is a request for executing “call back processing”. That is, in the modes of FIG. 15 and FIG. 19, the call back process is performed in response to the operation of the store clerk S (pressing the “call back” button), but the call is automatically performed regardless of the operation of the store clerk S. A return process may be performed. According to this, the store clerk S can perform a recall (re-designation) immediately without performing a call back process.

  Further, in a mode in which a call-back request is transmitted instead of the call-back confirmation request, the recall (re-designation) may be automatically performed regardless of the operation of the store clerk S. That is, the registration device 10 may automatically perform a call back process and a recall when a call back request is received.

  For example, in the case of the second power OFF operation shown in FIG. 19, the checkout apparatus 20-1 transmits a call back request after restarting. That is, when the registration device 10-1 receives the call-back request, the settlement device 20-1 is in a state where it can receive transaction information. Accordingly, the registration device 10-1 that has received the call-back request may perform call-back processing and re-specify the settlement device 20-1 that is the source of the call-back request as the re-designation designation destination. On the other hand, in the case of the first power-off operation shown in FIG. 15, when the registration device 10-1 receives the call back request, the settlement device 20-1 is not in a state where it can receive the transaction information. Accordingly, the registration device 10-1 that has received the call-back request executes the call-back process, and as a redesignated designation destination, a settlement device 20-2 that is different from the settlement device 20-1 that is the source of the call-back request. Can be specified again. Note that the registration apparatus 10-1 may re-specify the settlement apparatus 20-1 that is the transmission source of the call-back request after the settlement apparatus 20-1 is ready to receive transaction information.

  When the second power-off operation is performed, the checkout device 20 uses another registration device 10 (for example, the registration device 10) other than the registration device 10 (the registration device 10-1 in FIG. 19) that is the transmission source of the transaction information. -2) may also be sent to the call back confirmation request. The same applies when a call-back request is transmitted. The same applies when the first power OFF operation is performed. As a result, the call back confirmation request can be transmitted without specifying the transmission destination.

  As described above, in the case of transmitting the call back confirmation request to another registration apparatus 10, the other registration apparatus 10 may ignore the call back confirmation request. When the call back confirmation request including the transaction number is transmitted and received, the registration device 10 executes the registration process for the call back confirmation request in its own device based on the transaction number included in the call back confirmation request. It is determined whether the request is a call back confirmation request for the transaction, and if the request is not a call back confirmation request for the transaction for which registration processing has been executed by the own device, the received call back confirmation request may be ignored. Alternatively, it is determined whether or not there is an unsettled transaction for which the settlement apparatus 20 that is a transmission source of the call back confirmation request is a transmission destination, and if there is no such unsettled transaction, the received call back confirmation request is ignored. May be. On the other hand, when the call back confirmation request including the transaction number is not transmitted and received, it is determined whether or not there is an unsettled transaction with the settlement apparatus 20 that is the transmission source of the call back confirmation request as a transmission destination. If there is no checkout transaction, the received call back confirmation request may be ignored. The same applies when the call-back request is ignored.

  As shown in FIGS. 15 and 19, when the first power OFF operation or the second power OFF operation is performed, the settlement apparatus 20 transmits a call back confirmation request to the registration apparatus 10. It is only necessary that the registration device 10 can receive the call-back confirmation request transmitted from 20, and the checkout device 20 may directly transmit to the registration device 10 or via another device (for example, the store controller 30). Alternatively, it may be transmitted to the registration device 10. The same applies to the transmission of the call back request.

  Further, in FIG. 17A, an example in which the message “calling required” is displayed in the vicinity of the “settlement machine 1” button has been described, but it may be displayed at another position. For example, it may be displayed in the vicinity of a button for displaying the unsettled list screen (“unsettled one” button in the figure), or in the upper part (including the upper end) or the lower part of the unsettled list screen It may be displayed.

  In addition to the above, other various information may be displayed on the product registration screen and the unpaid list screen. For example, the status (state or the like) of the settlement apparatus 20 may be displayed on the product registration screen. For example, as shown in FIG. 16A or the like, the checkout corresponding to each of the buttons corresponding to the respective checkout devices (“Settlement machine 1” button, “Settlement machine 2” button, “Settlement machine 3” button). You may display the status regarding the apparatus 20 (the adjustment apparatus 20-1, the adjustment apparatus 20-2, the adjustment apparatus 20-3). Specifically, the status regarding the settlement apparatus 20 corresponding to each button (the settlement machine 1, the settlement machine 2, and the settlement machine 3) may be displayed in a badge format. In other words, the status may be displayed in such a manner that a badge (brooch) expressing the status is attached to each button. The status related to the settlement apparatus 20 includes information related to whether or not the power is turned on, information related to the network (communication availability), and information related to change. It should be noted that the message “calling required” is also displayed in a badge format as shown in FIG.

  For example, in the case of FIG. 16 (A), the “Cash machine 1” button displays “Changing change” in a badge format, the “Cash machine 2” button displays “Offline” in a badge format, The “3” button displays “offline” in a badge format. “Changing change” indicates that the change of the settlement apparatus 20 corresponding to the button is insufficient. “Offline” indicates that at least one of the registration apparatus 10 and the settlement apparatus 20 corresponding to the button is in an offline state or the settlement apparatus 20 corresponding to the button is not turned on. ing. Note that the displayed status is not limited to the exemplified “lack of change” or “offline”. For example, “near end” indicating that the change is short, or change (for example, 10,000 yen bill) “Near Full” indicating that the battery is almost full may be displayed. Note that the display position of the badge is not limited to the display position shown in FIG. 16A (the display position where the entire badge is displayed outside the button display area (upper side)). May be displayed in the display area of the button (note that it is not an example of display in the display area of the button, but in FIG. 20, for example, a part of the badge “lack of change” is displayed. The display position may be such that all of the badges fit within the display area of the button). The status display is not limited to that in the badge format, and a text display area for displaying a word (text) indicating the status may be provided in the button, and the status may be displayed in the display area. Further, the button color may be changed according to the status.

  In addition, two or more badges can be attached to one button. For example, two badges “offline” and “call back required” are attached to the “Checkout Machine 1” button in FIG. However, one badge determined based on a predetermined standard (priority information based on importance and urgency) may be attached (attached). For example, by storing priority information indicating that the call-back process has a higher priority than the offline state. In the “Checkout machine 1” button in FIG. 17A, one “call back necessary” badge is displayed.

  FIG. 20 is another display example of the unsettled list screen. Similarly to the product registration screen, for example, as shown in FIG. 20, the status (state etc.) of the settlement apparatus 20 may be displayed in the left area of the unpaid list screen (area of the unpaid list). As shown in FIG. 20, “change shortage” is displayed in a badge format in the display area of “settlement machine 2” of the unsettled call transaction information in the “1” column and “3” column, and the “2” column is not yet displayed. “Offline” may be displayed in a badge format in the display area of “settlement machine 1” of settlement transaction information.

  In addition, member information may be displayed on the unpaid list screen. For example, the member number “1234” may be displayed as the member number of the transaction as shown in the unsettled call transaction information in the “2” column of FIG. The membership number displayed on the unpaid list screen is, for example, a number obtained by reading a membership card. That is, for example, when the clerk S reads the membership card presented from the customer C who is a member before and after (or during) the registration process, the registration device 10 reads the transaction information (for example, FIG. 20). As unsettled transaction information). As shown in FIG. 20, member information (member number) may also be displayed in the right region (detailed information region). Further, the member number may be displayed on the product registration screen at the time of reading.

  Further, as shown in FIG. 20, the elapsed time from the end time of the registration process may be displayed on the unsettled list screen. The elapsed time displayed on the unsettled list screen is an elapsed time based on a designated time of the settlement apparatus 20 (a pressing time when a button for designating the settlement apparatus 20 is pressed). In the case of FIG. 20, the elapsed time “00:00:27” is displayed in the unsettled called transaction information in the “1” column, and the elapsed time is displayed in the unsettled called transaction information in the “2” column. “00:01:13” is displayed, and the unsettled call transaction information in the “3” column displays the elapsed time “00:01:27”, both at 21:06:30 It is the elapsed time at (current).

  In addition, you may vary a display mode according to elapsed time. For example, when the elapsed time exceeds a predetermined time (for example, 1 minute) (or when the elapsed time reaches the predetermined time), the elapsed time does not exceed the predetermined time (or the elapsed time reaches the predetermined time). The elapsed time may be displayed in a more conspicuous mode (a conspicuous color, a conspicuous size, a conspicuous typeface, etc.) than a case where the time has not been reached. Further, the elapsed time may be displayed when a predetermined condition is satisfied. For example, the elapsed time may be displayed when the elapsed time exceeds a predetermined time (for example, 1 minute) (or when the elapsed time reaches the predetermined time).

  It should be noted that, in the aspect of using a bill as described in other embodiments, not in the aspect of specifying the settlement apparatus 20, the specified time of the settlement apparatus 20 (the button for designating the settlement apparatus 20 is pressed) Instead of the elapsed time based on the (pressing time), an elapsed time based on the issuance time of the bill (or the pressing time when the button for issuing the bill is pressed) may be used. In addition to the elapsed time based on the issuance time (or pressing time) of the bill, the elapsed time based on the bill reading time (the time when the checkout device 20 reads the bill) is displayed. May be. In the stage before the bill is read by the checkout device 20, the elapsed time based on the reading time may not be displayed. In addition to the elapsed time based on the issuance time (or press time) of the bill, the elapsed time based on the bill reading time can be displayed to grasp the situation in more detail.

  Moreover, you may display the information regarding the used gift certificate on the unpaid list screen. For example, as shown in the unsettled call transaction information in the “3” column of FIG. 20, the gift certificate name “gift certificate A” may be displayed as information related to the gift certificate used in the transaction. In addition, the information regarding the gift certificate displayed on the unpaid list screen is, for example, when the clerk S acquires the gift certificate from the customer C before and after (or during) the registration process. The transaction information (for example, 20 is not settled as described above) by inputting the fact that it is used, or when the barcode is present on the gift certificate, by causing the registration device 10 to read the barcode. Transaction information). In addition, you may display the information regarding a gift certificate on a goods registration screen at the time of reading.

  In addition, a sort button may be displayed (arranged) on the unsettled list screen as shown in FIG. The sort button allows the clerk S to perform various sorts such as the newest / oldest order of the registration processing end time, the highest / lowest total amount, and the highest / lowest purchase points. It is possible to easily find unsettled and called transaction information. In addition, it is possible to easily confirm whether or not the settlement process has been completed for a certain transaction (that is, whether there is unsettled call transaction information for a certain transaction). In order to switch the sort type, a date button, a score button, a total amount button, etc. may be displayed (arranged), but a sort button is not provided without arranging a date button, a score button, a total amount button, etc. Every time the button is pressed, the registration process ends in the newest order → the registration process ends in the oldest order → the total amount increases in order → the total amount decreases in order → the purchase number increases in order → the purchase number decreases As described above, the sort type may be switched.

  In addition, in the unsettled list screen, in addition to the “call back” button for executing the recall process for one unsettled called transaction information, two or more unsettled called transaction information are collectively (collectively). ) A button for executing a call back process may be displayed (arranged). That is, as described above, when the “call back” button is pressed in a state where a certain unsettled call transaction information is selected, the registration device 10 selects the selected unsettled call transaction information. When the button for executing the call back processing is collectively pressed for two or more unsettled called transaction information, the two or more unsettled called transaction information is collectively collected. Call back processing may be executed.

  For example, as shown in FIG. 20, as a button for collectively (collectively) executing call back processing for two or more unsettled call transaction information, as shown in FIG. 20, a “select all” button, “select settlement machine 1” A button, a “checkout machine 2 selection” button, and a “checkout machine 3 selection” button may be displayed (arranged). The “select settlement machine 1” button is a button for executing a call-back process on all unpaid-calling transaction information specifying the settlement apparatus 20-1. The “select settlement machine 2” button is a button for executing a call-back process for all unpaid-calling transaction information specifying the settlement apparatus 20-2. The “Choice machine 3 selection” button is a button for executing a call back process for all unpaid call-up transaction information specifying the settlement apparatus 20-3. The “select all” button is a button for executing a recall process for all unsettled and called transaction information. Therefore, for example, in the example of FIG. 20, when the “select settlement machine 1” button is pressed, the registration device 10-1 stores all unsettled call transaction information (“ Call back processing is executed for one unsettled call transaction information) in the column “2”. Further, for example, in the example of FIG. 20, when the “select settlement machine 2” button is pressed, the registration apparatus 10-1 selects all the unpaid-up call transaction information (“1” ”Column and“ 3 ”column two unpaid call transaction information), the call back process is executed. Further, for example, in the example of FIG. 20, when the “select all” button is pressed, the registration device 10-1 determines that all unpaid-call transactions that specify the settlement device 20-1 and the settlement device 20-2. Call-back processing is executed on information (three unpaid call transaction information in the “1” to “3” columns). In addition, when there is no unsettled call transaction information to be called back, the corresponding button may be displayed lightly. For example, in the example of FIG. 20, since there is no unsettled call transaction information specifying the settlement apparatus 20-3, the “settlement machine 3 selection” button may be displayed lightly.

  Moreover, you may enable it to perform a recall process for two or more unsettled call transaction information arbitrarily selected by the store clerk. For example, the “continuous selection” button can be displayed (arranged), and each time the “continuous selection” button is pressed, unsettled call transaction information can be selected one by one from the left area (unsettled call list area). In this manner, by finally pressing the “call back” button, the call back processing may be executed for all unsettled called transaction information selected before the “call back” button is pressed.
