  (First Embodiment) FIG. 1 shows the appearance of a settlement system according to the first embodiment of the present invention. The settlement system includes a coin change machine 100 that performs coin deposit / withdrawal processing, and a register 300 that registers customer purchases. Further, the settlement system may include a drawer for storing banknotes and spare coins, a small safe or the like (not shown).

  FIG. 2 is a block diagram of the coin change machine 100, and the configuration of the coin change machine 100 will be described with reference to FIGS. 1 and 2.

  The coin change machine 100 includes a coin receiving unit 114 that receives coins from the outside, a coin identifying unit 101 that performs identification counting of the received coins received from the coin receiving unit 114, and a received coin according to a face value according to the identification result by the coin identifying unit 101. A coin storage unit 106 for storing the coins and a coin dispensing unit 116 for paying out the coins to the outside are provided.

  As shown in FIG. 1, the coin change machine 100 includes a housing 110 having an operation display unit 112 on the front upper surface. A coin receiving unit 114 and a coin dispensing unit 116 are provided at the front of the housing 110.

  The coin receiving unit 114 takes in the accepted coins one by one in a one-layer, one-row state. A deposit conveyance unit 103 that conveys the captured coins extends behind the receiving unit 114.

  In the middle of the deposit conveyance unit 103, a coin identifying unit 101 for identifying and counting coins and a branching unit 104 are provided. Based on the identification result of the coin identifying unit 101, the branching unit 104 guides (conveys) the coins dispensed (released) from the coin dispensing unit 116 such as reject coins to the dispensing conveyance unit 108.

  Coins stored in a machine such as normal coins are transported to the coin storage unit 106 by the deposit transport unit 103. The coin storage unit 106 stores coins by denomination, for example, stores coins in descending order from the upstream side of the deposit transport unit 103.

  The withdrawal conveyance unit 108 conveys the coins discharged from the coin storage unit 106 to the coin dispensing unit 116. Further, the withdrawal conveyance unit 108 conveys the coin guided from the branching unit 104 to the coin dispensing unit 116.

  Further, the coin change machine 100 is provided with a control unit 130 that controls each unit. The control unit 130 is communicably connected to the register 300, and transmits and receives various information. For example, the control unit 130 receives a command (payment command) for starting a depositing process from the register 300. In addition, the control unit 130 transmits the counting result of the received coins to the register 300.

  In addition, when the deposit coin includes the reject coin, the control unit 130 notifies the register 300 that the reject coin is included. Further, at this time, the control unit 130 displays on the operation display unit 112 that the reject coin has been included, or an illumination unit (not shown) such as a lamp that illuminates the coin dispensing unit 116 from which the reject coin has been dispensed. ) May blink.

  Further, the control unit 130 receives a change dispensing instruction including the amount of coins to be dispensed as change from the register 300. In addition, when the dispensing of the change coin based on the change dispensing instruction is completed, the control unit 130 notifies the register 300 of the completion of the dispensing.

  Further, the control unit 130 withdraws the change coin instructed to be withdrawn from the register 300 when the number of stored coins in the coin storage unit 106 becomes zero (empty) or an error occurs during the withdrawal of the change coin. If the payment cannot be made, unpaid information indicating the amount of change coins that cannot be withdrawn is created and transmitted to the register 300. A sensor for counting the number of withdrawals is provided at the coin outlet of each coin storage unit 106, and the amount of money withdrawn halfway is obtained from the count value of this sensor. From the difference between this amount and the amount of change coins withdrawn instructions, the amount of change coins that cannot be withdrawn can be obtained.

  FIG. 3 shows a block configuration of the register 300. As shown in FIGS. 1 and 3, the register 300 includes a display unit 302 that displays various types of information, a keyboard 304 that receives manual input of various types of information and instructions from an attendant, and a printer that outputs a receipt on which transaction details are printed. 306, a communication unit 308 that is communicably connected to the coin change machine 100, an arithmetic control unit 310, and a memory 312 that stores a settlement processing program.

  The keyboard 304 has a numeric keypad, and can accept manual input of deposit information regarding money that cannot be deposited into the coin change machine 100 out of the customer's paid currency. Here, the money which cannot be deposited into the coin change machine 100 is a bill, a reject coin, a cash voucher, or the like.

  Further, the register 300 includes a reading unit (not shown) that reads a barcode attached to a customer's purchased product. The register 300 can acquire and register the merchandise information of the customer's purchased merchandise by reading the bar code by the reading unit or manually inputting the data from the keyboard 304 by the attendant.

  As illustrated in FIG. 1, the register 300 may include a display unit (customer display) 302a for a customer. In addition, the display unit 302 may be a touch panel, and in that case, input of merchandise information of customer-purchased merchandise, deposit information about money that cannot be deposited into the coin change machine 100, or the like can be received from the staff.

  The arithmetic control unit 310 is connected to each unit of the register 300, and exchanges data and controls operations. Further, the arithmetic control unit 310 can transmit a deposit command from the communication unit 308 to the coin change machine 100.

  In addition, the arithmetic control unit 310 executes a settlement processing program stored in the memory 312. FIG. 4 shows a functional block diagram realized by the arithmetic control unit 310 executing the settlement processing program. By executing the settlement processing program, a purchase price calculation unit 320, a change calculation unit 322, and an output unit 324 are realized.

  The purchase price calculation unit 320 uses the product information acquired via the reading unit or the like to calculate the purchase price of the customer's purchase product (total price if there are multiple products). For example, a table having a combination of product information and its amount is stored in the memory 312, and the purchase price calculation unit 320 can obtain the price of the purchased product by searching the table using the product information. .

  The change calculation unit 322 calculates the total deposit amount by adding the counting result of the received coins received from the coin change machine 100 via the communication unit 308 and the deposit information manually input from the staff via the keyboard 304. Then, the change calculation unit 322 calculates the change amount by subtracting the purchase amount calculated by the purchase amount calculation unit 320 from the total deposit amount. Furthermore, the change calculation unit 322 divides the calculated change amount into bills and coins, and outputs a change dispensing instruction corresponding to the coins to the coin change machine 100 via the communication unit 308. Further, the change calculation unit 322 notifies the output unit 324 of the change bill information corresponding to the bill of the change.

  For example, when the change amount is 1240 yen, the change calculation unit 322 outputs a change dispensing instruction for dispensing a change coin of 240 yen (lower 3 digits) to the coin change machine 100, and a change bill of 1000 yen. Is notified to the output unit 324.

  The output unit 324 outputs and displays the change banknote information received from the change calculation unit 322 to the display unit 302 as unpaid change information representing change that cannot be withdrawn from the coin change machine 100. In addition, when the output unit 324 receives from the coin change machine 100 via the communication unit 308 unpaid information indicating the amount of change coins that cannot be withdrawn, the unpaid information is also not stored. It outputs to the display part 302 and displays it as withdrawal change information. The unpaid change information may not be the amount but the number of denominations.

  The clerk confirms the change banknote based on the unpaid change information displayed on the display unit 302, takes out the banknote from a drawer (not shown), and hands it to the customer.

  Further, while the coin change machine 100 withdraws change coins, a part of the change is withdrawn due to a shortage of coins (empty) or a failure of the coin change machine 100. When the coin change machine 100 stops in a state where there is no money, information about the change coins that cannot be withdrawn is displayed on the display unit 302. The clerk takes out a coin from a drawer (not shown) storing spare coins based on the display content of the display unit 302, and the coins already paid out to the coin payout unit 116 of the coin change machine 100. Hand it over to the customer.

  If the coin changer is empty or an error occurs, the clerk manually counts the coins that have been paid out to the coin dispensing unit, and if there is a change in the amount that is taken out of the drawer, it may cause a miscalculation of the change. , Cash could not be managed accurately. However, in the present embodiment, it is possible to display on the display unit 302 information about change bills and change coins that cannot be withdrawn. Therefore, it is possible to deposit the customer's payment and change the cash while managing the cash strictly and accurately.

  Next, a settlement method using such a settlement system will be described.

  First, the case where the customer's payment is only a coin and the reject coin is not included in the payment coin will be described with reference to the timing chart shown in FIG.

  (Step S <b> 104) The coin change machine 100 transmits the counting result of the received coins to the register 300.

  (Step S105) The change calculation unit 322 of the register 300 calculates the total deposit amount from the counting result of the deposited coins received from the coin change machine 100 in Step S104. The total deposit amount is displayed on the display unit 302 of the register 300 and the customer display.

  (Step S106) The total deposit amount is confirmed. For example, an attendant may operate the keyboard 304 to give a deposit confirmation instruction to the register 300, or automatically when there is no additional deposit to the coin change machine 100 and the total deposit amount has not changed for a predetermined time. The total deposit amount may be fixed. At this time, the confirmed total deposit amount is equal to or greater than the purchase amount.

  (Step S107) The change calculation unit 322 of the register 300 calculates the change amount based on the total deposit amount and the purchase amount.

  (Step S <b> 108) The change calculation unit 322 of the register 300 outputs to the coin change machine 100 a change dispensing instruction that instructs to withdraw coins out of the change amount. In the example shown in this figure, since the customer's payment is only a coin, it is assumed that the change is an amount composed only of the coin.

  (Step S109) The coin change machine 100 withdraws the change coin based on the change dispensing instruction. The clerk hands the dispensed change coin to the customer.

  (Step S110) The coin change machine 100 notifies the register 300 of the completion of the change coin withdrawal.

  (Step S <b> 111) The printer 306 outputs a receipt on which the transaction details including the product information of the customer's purchased product, the purchase amount, the customer's payment amount, the change amount, and the like are printed. The clerk hands the output receipt to the customer.

  Next, the case where banknotes are included in the customer's payment money and the reject coins are not included in the payment coins will be described using the timing chart shown in FIG.

  (Step S201) The product information of the product purchased by the customer is registered in the register 300, and the purchase price is calculated (by the purchase price calculation unit 320).

  (Step S202) The register 300 transmits a deposit command to the coin change machine 100. When the coin change machine 100 receives the deposit command, it enters a state of waiting for the deposit of coins.

  (Step S <b> 203) The customer's payment coin is deposited into the coin change machine 100. The coin change machine 100 performs a deposit process including identification and counting of coins.

  (Step S204) The coin change machine 100 transmits the counting result of the received coins to the register 300.

  (Step S <b> 205) The attendant manually inputs the deposit information about the customer's payment banknote using the keyboard 304 of the register 300.

  (Step S206) The change calculation unit 322 of the register 300 adds the counting result of the deposited coin received from the coin change machine 100 in Step S204 and the deposit information manually input from the staff via the keyboard 304 in Step S205. To calculate the total deposit amount. The total deposit amount is displayed on the display unit 302 of the register 300 and the customer display.

  (Step S207) The total deposit amount is confirmed.

  (Step S208) The change calculation unit 322 of the register 300 calculates the change amount based on the total deposit amount and the purchase amount.

  (Step S210) The change calculation unit 322 notifies the output unit 324 of the change bill information corresponding to the bill of the change. The output unit 324 outputs the change banknote information notified from the change calculation unit 322 to the display unit 302 as undrawn change information and displays the information.

  The clerk confirms the unpaid change information displayed on the display unit 302 and takes out the change banknote from the drawer (not shown).

  The display unit 302 may display the undrawn change information until the merchandise information of the purchased product of the next customer (transaction) is registered. You may input from these.

  If there is no change banknote, this step is omitted.

  (Step S211) The coin change machine 100 withdraws a change coin based on a change dispensing instruction. The attendant hands the changed change coin and the change banknote taken out from the drawer (not shown) in step S210 to the customer.

  (Step S212) The coin change machine 100 notifies the register 300 of the completion of the change coin withdrawal.

  (Step S213) The printer 306 outputs a receipt on which the transaction details including the product information of the customer's purchased product, the purchase amount, the customer's payment amount, the change amount, etc. are printed. The clerk hands the output receipt to the customer.

  In this way, using a payment system without a banknote change machine, it is possible to deposit a customer's payment and change money in a so-called deposit confirmation mode. Since the coin change machine 100 is used for coins, accurate deposit / withdrawal processing can be performed. Moreover, since the information about the change banknote that cannot be dispensed by the coin change machine 100 is displayed on the display unit 302, the clerk can handle the change banknote without checking the amount of money while checking the displayed information.

  Next, the case where the customer's payment is only coins and the reject coins are included in the payment coins will be described using the timing chart shown in FIG.

  (Step S301) The product information of the product purchased by the customer is registered in the register 300, and the purchase price is calculated (by the purchase price calculation unit 320).

  (Step S302) The register 300 transmits a deposit command to the coin change machine 100. When the coin change machine 100 receives the deposit command, it enters a state of waiting for the deposit of coins.

  (Step S <b> 303) The customer's payment coin is deposited into the coin change machine 100. The coin change machine 100 performs a deposit process including identification and counting of coins.

  (Step S304) The coin change machine 100 releases a reject coin from the coin dispensing unit 116.

  (Step S305) The coin change machine 100 transmits the counting result of the received coins (not including reject coins) to the register 300.

  (Step S306) The coin change machine 100 notifies the register 300 that a reject coin has been included.

  (Step S307) The coin change machine 100 displays on the operation display unit 112 that a reject coin has been included, or blinks an illumination unit (not shown) such as a lamp that illuminates the coin dispensing unit 116. Inform the staff of the occurrence of reject coins.

  (Step S308) The clerk visually confirms the reject coin, and manually inputs the deposit information (for example, the number of denominations and the amount of money) about the reject coin from the keyboard 304. The reject coin is stored in a dedicated storage unit.

  (Step S309) The change calculation unit 322 of the register 300 adds the counting result of the deposited coin received from the coin change machine 100 in Step S305 and the deposit information manually input from the attendant via the keyboard 304 in Step S308. To calculate the total deposit amount. The total deposit amount is displayed on the display unit 302 of the register 300 and the customer display.

  Subsequent steps S310 to S315 are the same as steps S106 to S111 shown in FIG.

  As described above, regarding the reject coins that cannot be deposited into the coin change machine 100, the information can be manually input from the register 300 and processed for deposit after the attendant visually confirms.

  Next, a case where the dispensing operation is stopped due to an empty or error while the coin change machine 100 is dispensing the change coin will be described with reference to the timing chart shown in FIG.

  Steps S401 to S408 are the same as steps S101 to S108 shown in FIG.

  (Step S409) The coin change machine 100 starts withdrawing change coins based on the change withdrawal instruction.

  (Step S410) An empty or error occurs during the withdrawal of change coins, and the withdrawal operation of the coin change machine 100 stops.

  (Step S <b> 411) The coin change machine 100 creates unpaid information indicating the amount of change coins that cannot be withdrawn, and transmits it to the register 300.

  (Step S412) The output unit 324 of the register 300 receives the unpaid information from the coin change machine 100 via the communication unit 308. Then, the output unit 324 outputs the non-withdrawal information to the display unit 302 as non-withdrawal change information for display.

  Based on the unpaid change information displayed on the display unit 302, the clerk takes out the unpaid change coins from a drawer (not shown) that stores spare coins, and changes the coins. The coins that have already been paid out to the coin payout unit 116 of the machine 100 are handed to the customer.

  (Step S413) The printer 306 outputs a receipt on which the transaction details including the product information of the customer's purchased product, the purchase amount, the customer's payment amount, the change amount, etc. are printed. The clerk hands the output receipt to the customer.

  In the example shown in this figure, the register 300 has not received a notice of withdrawal completion from the coin change machine 100. Accordingly, the clerk may input a transaction end (receipt output) instruction using the keyboard 304, and the printer 306 may output a receipt based on the instruction.

  As described above, when the dispensing operation of the coin change machine 100 is stopped due to an empty or error during the withdrawal of the change coin, information on the change coin that has not been dispensed can be displayed on the display unit 302. . The attendant may confirm the information displayed on the display unit 302 and take out the missing change coins from the drawer (not shown). Therefore, compared with the case where the number of coins that have been withdrawn is counted manually and the amount of change that is insufficient is calculated by the clerk himself, it is possible to prevent occurrence of counting and calculation errors and to manage cash accurately.

  In addition, the coin change machine 100 creates unpaid information by using a detection result of a sensor (not shown) that counts the number of withdrawals provided at the coin outlet of each coin storage unit 106. However, when the cause of the stop of the coin change machine 100 is an error such as a coin jam at the coin discharge port or a conveyance abnormality in the dispensing conveyance unit 108, the accuracy of the unpaid information can be lowered. Therefore, when the coin change machine 100 stops due to such a factor, after canceling the error of the coin change machine 100, all the dispensed coins are deposited into the coin change machine 100, and the change coins are taken out again. You may make money.

  The payment system according to the present embodiment can cope with various situations by combining the processes shown in FIGS. For example, when bills are included in the customer's payment money and reject coins are included in the payment coins, the processing shown in FIG. 6 is combined with the processing shown in FIG. Specifically, the change calculation unit 322 receives the payment information about the customer's payment banknote manually input from the keyboard 304 by the attendant and the payment information about the reject coin, and the counting result of the received coin received from the coin change machine 100. Is used to calculate the total deposit amount, and this total deposit amount is displayed on the display unit 302 and the customer display of the register 300 in step S206 (S309).

  Further, when the coin change machine 100 is stopped due to an empty or error in the state where there is a change bill, the process shown in FIG. 6 is combined with the process shown in FIG. Specifically, in step S210 (S412), the change banknote information corresponding to the banknote of the change and the unpaid information created by the coin change machine 100 are displayed on the display unit 302 as unpaid change information. Is displayed.

  Up to this point, the settlement system and the settlement method for performing the settlement process in the so-called deposit confirmation mode in which change is withdrawn after the payment of the customer's payment money has been described. Later, it is also possible to perform a settlement process in a so-called change-first mode in which the customer pays money.

  In the change advance mode, the change calculation unit 322 of the register 300 obtains the total amount of payment from the payment information input from the keyboard 304, and calculates the change amount. Moreover, the coin change machine 100 does not need to transmit the counting result of the deposited coin to the register 300.

  The settlement process in the change advance mode will be described with reference to FIGS. First, the case where the change is only coins will be described with reference to the timing chart shown in FIG.

(Step S501) The product information of the product purchased by the customer is registered in the register 300, and the purchase price is calculated (by the purchase price calculation unit 320).

  (Step S502) A clerk counts the customer's payment money (coins and banknotes) and manually inputs the money as deposit information.

  (Step S503) The register 300 calculates the change amount from the purchase amount and the deposit information.
