The POS terminal device 10 is associated with a CPU (Central Processing Unit) 28 for calculation, a ROM (Read Only Memory) 29 for storing a program, a RAM (Random Access Memory) 30 for work, and a product code. A hard disk drive 31 for storing unit prices and the like. The CPU 28 has a timer 42. The ROM 29 should be executed corresponding to the change machine error information (FIGS. 6A and 6B) for identifying the error type in the coin change machine 11 and the banknote change machine 12 and each change machine error information. It has a table associating operation procedures and error cancellation methods. In addition to the error types by the coin change machine 11 and the banknote change machine 12, this table should also be executed corresponding to error information for identifying the error type in the POS terminal device 10 itself and the POS peripheral device, and each error information. The operation procedure and the error canceling method are stored in association with each other. The RAM 30 has a POS number, transaction date, transaction number, transaction time, cashier name, details of a plurality of purchased items, total amount of deposits, input amount to the coin change machine 11 and bill change machine 12, charge amount and change amount. And so on. These CPU 28, ROM 29 and RAM 30 constitute a control unit 17.

  Further, the POS terminal apparatus 10 includes a communication controller 32 that controls packet communication via the LAN 13, a first display driver 33 that drives and controls the display on the operator display 19, and a drive controller that controls the display on the customer display 18. 2 and a change machine interface unit 35 that exchanges signal data with each of the coin change machine 11 and the banknote change machine 12. The communication controller 32 substantially constitutes the communication unit 16. The POS terminal device 10 includes a scanner controller 36 that controls the scanner 49, a keyboard controller 38 that accepts key input operations on the keyboard 37, a printer controller 40 that controls printing and receipt issuing operations by the receipt printer 39, and these. A system bus 41 to be accommodated, an electronic journal storage unit 47 for storing journal data files, and a card reader controller 52 for controlling the card reader 51 are provided. These hard disk drive 31, receipt printer 39, scanner 49, keyboard 37, electronic journal storage unit 47, and card reader 51 are all POS peripheral devices. A disk controller (not shown) that drives the hard disk drive 31, a printer controller 40, a scanner controller 36, a keyboard controller 38, and a card reader controller 52 constitute a peripheral device interface unit 50. As an example, the peripheral device interface unit 50 arbitrates an access request from each peripheral device to the control unit 17, converts a data format, and controls data transfer timing. The peripheral device interface unit 50 and the change machine interface unit 35 are interface units that transmit / receive data to / from the coin change machine 11, the bill change machine 12, and these POS peripheral devices.

  The coin change machine 11 has a RAM 43 that is read by the control unit 17 of the POS terminal device 10. The RAM 43 stores a state file that stores the change machine state of the coin change machine 11. The change machine state refers to a state of operation of the coin change machine 11 such as a state of waiting for an instruction from the POS terminal device 10, a state of registering a purchased product, a state of paying out change, and a state where an error has occurred. When an error occurs in the coin change machine 11, the coin change machine 11 writes the details of this error in the status file. The bill change machine 12 also has a RAM 44, and a state file is stored in the RAM 44. In the state file on the bill change machine 12 side, details of the error are written when an error occurs in the bill change machine 12. The RAM 44 is read by the POS terminal device 10.

  Further, the plurality of other POS terminal apparatuses 10 have substantially the same configuration as that of the POS terminal apparatus 10 having the POS number “1”. A unique POS number is assigned to the POS number of the other POS terminal apparatus 10. These POS terminal devices 10 are arranged in the checkout lane. A plurality of POS terminal devices 10 form a store system via the LAN 13. The store system is connected to a maintenance company that provides online operation support and failure recovery support, and can be diagnosed by maintenance personnel. This store system is connected to the head office system via a telecommunication line such as a public network, the Internet, or a virtual private network. These store system and headquarter system constitute a POS system.

  One of the plurality of POS terminal devices 10 having such a configuration is activated as a master device, and the other POS terminal devices 10 are activated as slave devices. The master machine acquires the stocks of all the POS terminal devices 10 and the number and denominations of the change actually stored as information on the entire store system. Each of the operating POS terminal devices 10 is assigned an operator having a normal level skill who has received a cash register operation education.

  For example, the POS terminal device 10 with the POS number “1” will be described. During normal operation, the scanner 49 reads the barcode attached to the product by the operation of the operator in charge of the POS number “1”. The POS terminal device 10 searches the hard disk drive 31 with the barcode obtained by this registration process, and acquires the unit price, weight, product display, etc. of the product code corresponding to the barcode. Following the search process, the POS terminal apparatus 10 performs a payment process. The POS terminal device 10 calculates the total amount to be paid by the customer based on the acquired unit price, and registers it in the RAM 30. In this settlement process, the POS terminal device 10 accepts a deposit amount from a customer by pressing a numeric keypad on the keyboard 37, and calculates a change amount based on the total amount and the deposit amount.

  FIG. 4 is a diagram showing an example of transaction information stored in the RAM 30 on the POS terminal device 10 side. The control unit 17 writes the product number of the product purchased by the customer with respect to the POS number “1”, the deposit amount, the deposit amount, the change amount, and the like at a predetermined address in the RAM 30. This transaction information is read by the control unit 17 as information indicating a unit of one transaction. For example, when the control unit 17 sends the transaction information to the printer controller 40, the receipt printer 39 issues a receipt of the total amount and information of money transfer. The normal operation of the other POS terminal devices 10 is the same as that of the POS terminal device 10 having the POS number “1”.

  Next, an operation example when a change machine error occurs will be described. FIG. 5 is a flowchart for explaining an operation example of the POS terminal device 10 when a change machine error occurs. The figure shows a cash register No. of a plurality of, for example, n POS terminal devices 10. 2 shows an example of the operation of the control unit 17 of the POS terminal apparatus 10 installed in 1.

  In step A1, the POS terminal apparatus 10 constantly monitors whether any error has occurred (No route in step A1). During this time, the control unit 17 causes the customer display 18 to display advertisements and the like. The control unit 17 monitors each state of the coin change machine 11 and the banknote change machine 12 particularly when the coin change machine 11 and the banknote change machine 12 are performing the deposit / withdrawal operation. When the POS terminal device 10 with the POS number “1” detects that an error has occurred in step A1, the POS terminal device 10 passes the Yes route and determines the error type in step A2. When the error type is a change machine error in the coin change machine 11 or the banknote change machine 12, the control unit 17 is a state file in which the state of the coin change machine 11 is described, or a state file in which the state of the banknote change machine 12 is described. Is read.

  FIG. 6A is a diagram showing an example of the data structure of the state file of the coin change machine 11. A state file 45 shown in the figure is a data file stored in the RAM 43 of the coin change machine 11 of the POS terminal device 10. The status file 45 stores deposit / withdrawal coin information and change machine error information in association with the transaction number. The transaction number is a unique number assigned to each transaction. The deposit / withdrawal coin information includes the denomination of the inserted coin detected by the deposit sensor for denomination provided in the coin change machine 11 and the denomination identification provided near the payout opening in the coin change machine 11. The type of the payout coin detected by the payout sensor. The deposit / withdrawal coin information stores the number of coins for each denomination.

  FIG. 6B is a diagram showing an example of the data structure of the state file of the banknote change machine 12, in which the state file 46 stored in the RAM 44 of the banknote change machine 12 of the POS terminal device 10 is shown. Yes. The status file 46 stores deposit / withdrawal banknote information and change machine error information in association with the transaction number. The deposit / withdrawal banknote information indicates the banknote amount and the number of sheets detected by the deposit sensor provided in the banknote change machine 12 and the banknote amount and the number of sheets of the dispensed banknote detected by the withdrawal sensor provided in the dispensing unit. The change machine error information indicates error information at the time of deposit / withdrawal of the banknote change machine 12.

  In step A3 of FIG. 5, the POS terminal device 10 determines whether or not an error that has occurred in the coin change machine 11 and the banknote change machine 12 can be cleared in a short time, and the operation can be immediately restored. The ROM 29 stores in advance correspondence relationships between a plurality of error types including a change machine error and an operation procedure to be executed when the error occurs. The control unit 17 searches the ROM 29 according to the type of the change machine error that has occurred in the coin change machine 11 or the banknote change machine 12, and it is an error that can be handled by the operator, or a maintenance company can make an online diagnosis, or maintenance. Judge whether to call a member. The ROM 29 gives instructions and procedures for displaying whether to continue to wait for the customer in front of the POS terminal device 10 in association with the operation procedure to be executed or to guide the customer to another POS terminal device 10. Pre-stored.

  FIG. 7A and FIG. 7D are diagrams showing screen display examples of the customer display 18. FIG. 7B and FIG. 7C are diagrams showing a screen display example of the operator display 19. In step A3 of FIG. 5, for example, when the withdrawal sensor of the coin change machine 11 detects the occurrence of a withdrawal coin jam, the control unit 17 refers to the ROM 29 and determines that the error can be recovered in a short time. In step A4, the customer display 18 displays a message indicating that the customer is waiting for a waiting request, that is, waiting for a short time, as shown in FIG. 7A, for example. In step A5, the control unit 17 causes the operator display 19 to display a method for handling an error such as an operation procedure for canceling the error, as shown in FIG. 7B. In accordance with this display instruction, the operator removes the outer cover in front of the main body of the coin change machine 11 and removes the coin from the coin dispensing unit. When the operator inputs a necessary code on the keyboard 37, the coin change machine 11 starts to operate normally. When the control unit 17 receives an error release signal from the coin change machine 11 in step A6, the control unit 17 displays an error cancellation message on the operator display 19 and returns to normal operation. The controller 17 stops the display on the customer display 18.

  In Steps A1 to A3, for example, when a coin change is generated in the coin change machine 11, the control unit 17 determines that the error can be recovered in a short time, and passes through the route marked “Recoverable”. Then, each processing from step A4 to step A6 is performed.

  In addition, when the place where coins are jammed in step A3 is near the sorting hole inside the coin changer 11 or the like, the control unit 17 determines that the time is required by referring to the ROM 29, and the route marked “impossible to return”. Then, the display as shown in FIG. 7A is displayed on the customer display 18 (step A7). Subsequently, the control unit 17 displays a display as shown in FIG. 7C on the operator display 19 (step A8). In step A9, the control unit 17 performs a process of selecting another POS terminal device 10 that performs proxy withdrawal.

  FIG. 8 is a diagram for explaining an operation of a request for proxy withdrawal and a response. The above described symbols represent the same thing. Cash register No. 1 to n represent POS terminal devices 10 having POS numbers “1” to “n”, respectively. Cash register No. Suppose that a clogging 48 occurs at the deep part of the coin change machine 11 or the banknote change machine 12 associated with 1. When detecting that an error has occurred, the control unit 17 of the POS terminal device 10 with the POS number “1” reads the state file 45 from the coin change machine 11 and the state file 46 from the banknote change machine 12.

  In step A9, as indicated by (1) in FIG. 8, the POS terminal apparatus 10 sends a substitute withdrawal request message in which the identification POS number “1” is inserted by broadcast or multicast. Alternatively, the POS terminal device 10 with the POS number “1” may cause any one of the master machines to cast the proxy withdrawal request message. On the other hand, for example, when the POS terminal device 10 (another sales merchandise sales registration data processing terminal device) having the POS number “3” is not serving, when the POS terminal device 10 receives the proxy withdrawal request, the proxy withdrawal is performed. The reception of the request is notified to the operator in charge of this POS number “3”. For example, the operator display 19 displays the reception. Cash register No. The operator 3 inputs a confirmation to the POS terminal device 10 having the POS number “3” by operation. The POS terminal device 10 having the POS number “3” that is not in customer service returns a proxy withdrawal response message to the POS terminal device 10 having the POS number “1” as indicated by (2). The POS terminal device 10 having the POS number “1” reads the transaction information (FIG. 4) at the time of occurrence of the error from the RAM 30, and the packet including this transaction information is POS as indicated by (3) in FIG. 8. Send to terminal device 10.

  In step A10, the POS terminal device 10 having the POS number “1” on the side requesting the proxy withdrawal, as shown in FIG. The guidance guidance to the effect of prompting the settlement is notified to the device 10. In this step A10, the POS terminal apparatus 10 having the POS number “3” on the side of the proxy withdrawal is registered with the register No. 1 installed on the register counter. Turn on and blink the register pole lamp indicating 3. The POS terminal device 10 reads the transaction information received from the POS number “1” and resumes the settlement for the customer from the middle. Customer checkout ends. When it takes time to remove the clogging and clear the error, the POS terminal device 10 with the POS number “1” can finish the settlement without waiting for the customer during shopping.

  Further, in steps A1 to A3, the change machine error occurred in the coin change machine 11, but the processing by the POS terminal device 10 when the change machine error occurred in the banknote change machine 12 is a coin change. This is substantially the same as the case of the machine 11. In steps A1 to A3, for example, when the banknote change machine 12 deposits, the inserted banknote is identified as a fake coin, and when the banknote is rejected, the POS terminal device 10 is notified of the occurrence of an error. Under the control of the control unit 17, the operator display 19 displays the location where an error has occurred, the method for canceling the error, and the like. The operator removes the banknote in a short time, and then the banknote change machine 12 resumes operation. Similarly, when an error such as a banknote jam occurs when the banknote change machine 12 withdraws, the POS terminal device 10 is notified of an error that a banknote jam has occurred. The control unit 17 reads from the table in the ROM 29 a corresponding method corresponding to the banknote jam. If it is determined that it takes time to cancel the error, a proxy withdrawal request is transmitted to another POS terminal device 10 that is not performing customer service.

  The method of transmitting a proxy withdrawal request message when an error occurs in POS number “2” to POS number “n” and the method of executing proxy withdrawal are both the same as the example of POS number “1”.

  In summary, when an error occurs in the coin change machine 11 or the bill change machine 12, the POS terminal device 10 displays the error content and the error canceling method on the screen on the operator side. When the control unit 17 determines that it can be easily released, the POS terminal apparatus 10 displays a message such as “Please wait a while” on the screen on the customer side. When the control unit 17 determines that the POS terminal device 10 takes time to clear the error or cannot be cleared by the operator, a response guidance such as “Turn to the 3rd cash register” is displayed. I do.

  Further, when the POS terminal device 10 is in a transaction and cannot pay out from the coin change machine 11 or the banknote change machine 12 due to an error, the POS terminal device 10 guides the customer to another cash register which is not in a transaction by a screen display. At this time, guidance for prompting the customer to go to the cash register for surrogate withdrawal is displayed on the customer display of the POS terminal device 10 on the error occurrence side. The register number on the error occurrence side. 1 is cash register No. 1. The transaction information is transmitted to 3. Proxy withdrawals will be made. By transmitting the transaction information, a shift in the amount of money is prevented from occurring between the POS terminal device 10 on the transmission side and the other POS terminal device 10 on the reception side. Cash register No. 1 to cash register No. There is no shift in the amount of money between each of the n coin change machines 11 and the banknote change machines 12 and the POS terminal devices 10 connected thereto. The store system can manage the stocks of all the POS terminal devices 10 in real time.

  It is easier for the operator to understand the error location and the error canceling method, and to deal with an error. Since the POS terminal device 10 determines whether or not to respond to the customer due to the occurrence of an error, the operator's work efficiency is improved. Since the response flow after an error occurs is automatically displayed, the contents can be viewed by the customer. Even if an error occurs during the transaction, the transaction can be continued in another POS terminal device 10 by transmitting / receiving the transaction information shown in FIG. 4, so that there is no shift in the balance in the entire system.

  Even if the operator has a high operation capability, it is difficult for the operator to repair clogging in the deep part of the apparatus. When a change machine error occurs in the coin change machine 11 or the bill change machine 12, the difficulty level of dealing with the change machine error is more complicated than the difficulty level of dealing with an error that occurs in the drawer that stores money.
