Description

[[Technical Field]]

[0001] Embodiments of the present invention relate to an accounting apparatus and a program. [[Background Art]]

[0002] In commercial facilities such as food supermarkets, semi-self POS (Point Of Sales) systems in which a store clerk registers purchased products and a customer performs checkout for the purchased products using an accounting apparatus, and self-service POS systems in which a customer performs both product registration and checkout for purchased products are known. In such systems, the act of customers depositing a large amount of coins into the accounting apparatus has become noticeable. Semi-self or self-service accounting apparatuses are usually equipped with an automatic change dispenser and can count deposited coins. [[Prior Art Documents]] [[Patent Documents]]

[0003] [[Patent Document 1]] Japanese Unexamined Patent Application Publication No. 2018-22200 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0004] However, conventional accounting apparatuses as described above are not designed on the assumption that a large amount of coins will be deposited. When a large amount of coins is deposited, problems such as jams and overflows occur, which imposes a burden on store employees. Therefore, it is necessary to control the number of coins that can be deposited for each denomination. On the other hand, simple control that sets the number of depositable coins for each denomination causes errors in replenishment operations such as depositing wrapped coin rolls.

[0005] An object of an embodiment of the present invention is to provide a technology that makes it possible to restrict the number of deposited coins of the same denomination by a customer. [[Means for Solving the Problem]]

[0006] In one embodiment, the accounting device comprises a counting unit and a disbursement control unit. The counting unit counts the number of coins deposited by denomination based on the deposit of coins for payment of commercial transactions. If the number of coins of the same denomination counted by the counting unit exceeds a threshold for the number of coins that can be accepted in a single commercial transaction, the disbursement control unit controls the disbursement of the number of coins of the same denomination that exceeds the threshold.

[0008] The embodiments will be described below with reference to the drawings. In each drawing, the same reference numerals are used for identical components whenever possible, and redundant explanations are omitted.

[0009] [Embodiment] (Example configuration) Figure 1 is a block diagram illustrating a POS terminal 1 according to an embodiment. In this embodiment, as one form of accounting device, a self-service POS terminal that processes settlement of commercial transactions based on the customer's own operations is exemplified as POS terminal 1. Settlement of commercial transactions refers to, for example, the process of settling the price of goods purchased by a customer. Commercial transactions do not necessarily involve the buying and selling of goods. For example, POS terminal 1 may be an accounting device that settles payments incurred for the provision of services, such as facility usage fees or rental fees for borrowed items.

[0010] Self-service POS terminals perform not only payment processing but also the registration of items purchased by customers. This registration process involves registering sales data for the items purchased by the customer into memory. Based on this registered sales data, the self-service POS terminal calculates the total amount due for the transaction. To obtain this sales data, the self-service POS terminal has means for detecting the price of the items purchased by the customer. The transaction includes product registration, accounting processing for the registered products, and processing related to charging electronic money.

[0011] Common methods for detecting price include reading the barcode attached to the product with a scanner 15 (described later) or by operating an input device 16. Alternatively, a method may be used in which the price of the product is referenced in a product master or similar based on the product code read from the barcode.

[0012] POS terminal 1 is an electronic device including a processor 10, main memory 11, auxiliary storage device 12, change dispenser 13, communication interface 14, scanner 15, input device 16, display device 17, printing device 18, and card reader 19. The processor 10, main memory 11, auxiliary storage device 12, change dispenser 13, communication interface 14, scanner 15, input device 16, display device 17, printing device 18, and card reader 19 are connected to each other so that signals can be input and output. In Figure 1, the interface is labeled "I / F".

[0013] The processor 10 is the central part of the POS terminal 1. The processor 10 has the same hardware configuration as the processor 10 described above. The processor 10 is an element that makes up the computer of the POS terminal 1. For example, the processor 10 is a CPU (Central Processing Unit), but is not limited to this. The processor 10 may be composed of various circuits. The processor 10 loads a program that is pre-stored in the main memory 11 or auxiliary storage device 12 into the main memory 11. The program is a program that causes the processor 10 of the POS terminal 1 to implement the various parts described later and to execute the functions of each part. The processor 10 performs various operations by executing the program loaded into the main memory 11.

[0014] Main memory 11 corresponds to the main memory portion of POS terminal 1. Main memory 11 is an element that constitutes the computer of POS terminal 1. Main memory 11 includes a non-volatile memory area and a volatile memory area. In the non-volatile memory area of ​​main memory 11, the operating system or programs are stored. Main memory 11 uses the volatile memory area as a work area where data is rewritten as needed by the processor 10. For example, main memory 11 includes ROM (Read Only Memory) as a non-volatile memory area. For example, main memory 11 includes RAM (Random Access Memory) as a volatile memory area.

[0015] The auxiliary storage device 12 corresponds to the auxiliary storage section of the POS terminal 1. The auxiliary storage device 12 is a component constituting the computer of the POS terminal 1. The auxiliary storage device 12 is EEPROM (registered trademark) (Electric Erasable Programmable Read-Only Memory), HDD (Hard Disc Drive), SSD (Solid State Drive), or the like. The auxiliary storage device 12 stores the aforementioned program, data used when the processor 10 performs various processes, and data generated by processing performed by the processor 10. The auxiliary storage device 12 is an example of a storage unit.

[0016] When an operator inserts coins into the change machine 13, the change machine 13 sorts the coins by denomination and calculates an inserted amount (deposited amount). The change machine 13 sorts the coins by denomination and calculates the inserted amount (deposited amount). Coins sorted by denomination are stored in a safe. On the other hand, when change in coins needs to be dispensed, the change machine 13 extracts coins of the corresponding denomination from the safe. The change machine 13 dispenses the extracted coins. The operator may be interpreted as a customer, a store clerk, a user, or a person. Note that the change machine 13 may perform the same processing for banknotes.

[0017] The communication interface 14 includes various interfaces that communicably connect the POS terminal 1 with other electronic devices via a network in accordance with a predetermined communication protocol.

[0018] The scanner 15 is a device that reads various code symbols and acquires information from the code symbols. For example, a code symbol is a barcode symbol or a two-dimensional code symbol. The code symbol may include a product code symbol that records a code capable of identifying a product. A product code symbol is an image attached to a product. The code symbol may include a code symbol for code payment.

[0019] The input device 16 is a device that can input instructions to the POS terminal 1. For example, the input device 16 may include a keyboard. The input device 16 may also form a touchscreen together with the display device 17.

[0020] The display device 17 is a device capable of displaying various images under the control of the processor 10. For example, the display device 17 is a liquid crystal display or an EL (electroluminescence) display. The display device 17 is an example of a display unit. The display device 17 may also include an audio device that outputs sound.

[0021] The printing device 18 is a device for printing on receipts. For example, the printing device 18 is a thermal printer or an inkjet printer.

[0022] The card reader 19 reads the card data recorded on the magnetic stripe of the card medium.

[0023] The hardware configuration of POS terminal 1 is not limited to the configuration described above. POS terminal 1 allows for the omission and modification of the above-described components, as well as the addition of new components, as appropriate.

[0024] The various components implemented in the aforementioned processor 10 will now be described. The processor 10 implements a counting unit 110, a disbursement control unit 111, a display control unit 112, an accounting processing unit 113, a printing processing unit 114, and a determination unit 115. Each part implemented in the processor 10 can also be called a function. Each part implemented in the processor 10 can also be said to be implemented in the control unit which includes the processor 10 and the main memory 11.

[0025] The counting unit 110 determines whether or not a user has deposited coins for payment in a commercial transaction. Based on the deposit of coins for payment in a commercial transaction, the counting unit 110 counts the number of coins deposited by denomination. The counting unit 110 sorts the coins deposited by the user by denomination and counts the number of coins deposited (number of coins inserted) by denomination. The counting unit 110 may also calculate the amount of money inserted (amount of money inserted) based on the counted number of coins inserted. Here, "inserted" may be read as "deposit". The counting unit 110 may also count the number of banknotes deposited by denomination based on the user's payment in a commercial transaction.

[0026] The disbursement control unit 111 controls the disbursement of coins of the same denomination that exceed a threshold when the number of coins of the same denomination counted by the counting unit 110 exceeds a threshold. The threshold indicates, for example, the number of coins of each denomination that can be accepted in a single transaction. For example, the threshold is 20 coins. In one example, the disbursement control unit 111 disburses the coins that exceed the threshold each time it is determined that the threshold has been exceeded. In another example, the disbursement control unit 111 controls the disbursement of the coins that exceed the threshold after the settlement processing of the transaction. In this case, the disbursement control unit 111 performs overflow processing. Overflow processing includes storing the number of coins that exceed the threshold for each denomination in an auxiliary storage device. Overflow processing also includes storing an amount corresponding to the number of coins that exceed the threshold for each denomination, distinct from the amount of change disbursed based on accounting processing. The number of coins that exceed the threshold for each denomination are also called overflow coins. The amount equivalent to the number of coins exceeding the threshold for each denomination is also called the overflow amount or overflow withdrawal amount. The withdrawal control unit 111 performs cancellation processing based on the input of a payment cancellation instruction. The withdrawal control unit 111 performs transaction cancellation processing based on the determination unit 115, which will be described later, determining that a payment cancellation instruction has been input. The transaction cancellation processing includes processing to control the withdrawal of coins equivalent to the amount of coins deposited. The transaction cancellation processing includes processing to control the withdrawal of coins in the same configuration as the number of coins of each denomination deposited. The withdrawal control unit 111 controls the withdrawal of change based on the settlement processing of the transaction. The withdrawal control unit 111 switches the threshold settings according to the transaction mode switch. The withdrawal control unit 111 performs transaction mode switching processing based on the determination unit 115, which will be described later, determining that a transaction mode switching instruction has been input. Transaction modes include a self-service mode in which a customer deposits funds for payment of a commercial transaction, a normal transaction mode in which a store clerk deposits funds for processing a commercial transaction, a face-to-face transaction mode in which a face-to-face POS terminal used in a manner in which a store clerk and a customer interact face-to-face, operates as a POS terminal in which the store clerk registers products and the customer handles the payment, and a maintenance mode in which a store clerk replenishes the coins in the payment device.

[0027] The display control unit 112 controls the display on the display device 17. The display control unit 112 controls the display to display a message or a warning message on the display device 17 if the number of coins of the same denomination counted by the counting unit 110 exceeds another threshold value that is smaller than the threshold value. The display control unit 112 controls the display to display a message on the display device 17 if the number of coins of the same denomination counted by the counting unit 110 exceeds a threshold value. The display control unit 112 controls the display to display the number of coins to be withdrawn on the display device 17 in a manner that can be identified as a withdrawal based on the settlement process of a commercial transaction.

[0028] The accounting processing unit 113 processes the accounting of commercial transactions based on the user's input of accounting instructions. The accounting processing unit 113 determines whether or not the user has entered accounting instructions. Based on the input of accounting instructions, the accounting processing unit 113 processes the accounting of commercial transactions according to the user's selection of payment method. Payment methods include offline payments and online payments. Offline payments are payments that do not require the POS terminal 1 to cooperate with other electronic devices via a network. For example, offline payments include payments with cash and gift certificates. Online payments are payments that the POS terminal 1 performs in cooperation with other electronic devices via a network. For example, online payments include credit card payments, electronic money payments, debit card payments, and code payments. Accounting processing is also called payment processing.

[0029] The printing processing unit 114 controls the printing of the purchase receipt based on the accounting processing of the commercial transaction by the accounting processing unit 113.

[0030] The determination unit 115 performs various determination processes. The determination unit 115 determines whether the number of deposits of the same denomination counted by the counting unit 110 exceeds a threshold. The determination unit 115 determines whether the number of deposits of the same denomination counted by the counting unit 110 exceeds another threshold that is smaller than the threshold. The other threshold is, for example, a number less than the number of each denomination that can be accepted in a single transaction. For example, if the threshold is 20, the other threshold may be 14, etc. The determination unit 115 determines whether the user has entered an instruction to end the process. Based on the input of the user's instruction to end the process, the determination unit 115 terminates the transaction process. The determination unit 115 determines whether the user has entered an instruction to cancel the payment. The determination unit 115 determines whether the user has entered an instruction to switch the transaction mode. The thresholds and other thresholds may be set in advance, or they may be set or updated as appropriate by an administrator, etc.

[0031] This explains the cash payment screen. If the user selects cash payment on a payment selection screen (not shown), the display control unit 112 causes the display device 17 to display a cash payment screen.

[0032] Figure 2 shows an example of a cash payment screen displayed on the display device of a POS terminal according to the embodiment.

[0033] Figure 2 shows the cash payment screen SA. The cash payment screen SA includes an area RA that displays information related to cash payments, an area RB that displays information related to deposited coins, a back button BA, and an exit button BB. Area RA includes a total amount field, a deposit amount field, and a shortfall amount field. The total amount field displays the total amount. The deposit amount field displays the current deposit amount. The shortfall amount field usually displays the difference between the total amount and the deposit amount. The shortfall amount may also display the difference between the total amount and the amount accepted as the deposit amount. The amount accepted as the deposit amount is based on the number of deposited coins if the number of deposited coins for each denomination does not exceed the threshold. The amount accepted as the deposit amount is based on the number of deposited coins minus the number of coins exceeding the threshold if the number of deposited coins for each denomination exceeds the threshold. Information related to deposited coins includes the number of deposited coins, information showing the relationship between deposited coins and the threshold, information related to the coins to be withdrawn, etc.

[0034] Area RB includes fields for denomination, quantity, and remaining quantity. The denomination field displays the denomination of the coins. The quantity field displays the number of coins of each denomination that have been deposited. The remaining quantity field displays the remaining number of coins of each denomination that have been deposited. The remaining quantity is the number obtained by subtracting the number of deposited coins from the threshold number. The remaining quantity is also called the number of coins that can be deposited before reaching the threshold. The denomination field may include a warning indication based on the threshold, or another threshold that is smaller than the threshold. For example, the denomination field may include a text indication such as "Note" if the number of deposited coins exceeds another threshold that is smaller than the threshold. The denomination field may also include a text indication such as "Warning" if the number of deposited coins exceeds the threshold. Warning indications are not limited to text indications and include identifiable display forms such as symbols and icons. Display forms include text decoration such as text color, size, font, enclosed text, brightness or luminance, background color, background brightness or luminance, background pattern, frame color, flashing display, etc. Warning displays are not limited to the denomination column; they can be included anywhere on the cash payment screen SA. The area RB may be displayed when transitioning to the cash payment screen SA, or when the number of deposited coins exceeds a threshold smaller than the threshold value of another threshold. Figure 2 shows that 15 one-yen coins have been deposited, with 5 remaining until the threshold is reached. In Figure 2, because the number of one-yen coins deposited exceeds a threshold smaller than the threshold value of another threshold, the warning "Note" is displayed in the one-yen coin column. The same applies to other denominations of coins.

[0035] The back button BA is used to return to the payment selection screen. The exit button BB is used to end the payment process.

[0036] Figure 3 shows another example of a cash payment screen displayed on the display device of a POS terminal according to the embodiment.

[0037] Figure 3 shows the cash payment screen SB. The cash payment screen SB includes area RA which displays information related to cash payment, area RC which displays information related to deposited coins, a back button BA, and an exit button BB. Area RA, back button BA, and exit button BB are the same as those on the cash payment screen SA.

[0038] Area RC displays the number of coins deposited for each denomination using an indicator. For example, if 15 one-yen coins are deposited, the scale up to the 15 mark may be displayed in a different color. Area RC, like the cash payment screen SA, may include a warning display based on a threshold, or another threshold value smaller than the threshold. Figure 3 shows that 15 one-yen coins, 1 five-yen coin, and 10 ten-yen coins have been deposited. The same applies to other denominations of coins.

[0039] The RC area may also display a countdown indicating the number of cards remaining until the threshold is reached. The countdown may be displayed as numbers or as an indicator.

[0040] The area RC may be displayed when transitioning to the cash payment screen SB, or when the number of deposited coins exceeds another threshold that is less than the threshold value.

[0041] Figure 4 shows yet another example of a cash payment screen displayed on the display device of a POS terminal according to the embodiment.

[0042] Figure 4 shows the cash payment screen SC. The cash payment screen SC includes an area RA that displays information related to cash payment, an area RD that displays information related to deposited coins, a notification area RE, a back button BA, and an exit button BB. Areas RA, back button BA, and exit button BB are the same as those in the cash payment screen SA. Area RD is the same as area RB in the cash payment screen SA, but may be the same as area RC in the cash payment screen SB.

[0043] The notification area RE displays a warning message. The warning message may include a message informing the customer of the maximum number of coins that can be deposited. The warning message may include a message informing the customer that more coins than the maximum number of coins that can be deposited will be withdrawn. The warning message may include a message informing the customer that the number of coins deposited has exceeded a threshold. The warning message may include a message informing the customer that the number of coins deposited has exceeded another threshold. The warning message may include, for example, "Only 20 coins of the same denomination can be accepted in a single transaction," or "Coins marked with a [WARNING] symbol will be returned as change."

[0044] The notification area RE may be displayed when transitioning to the cash payment screen SC, or when the number of deposited items exceeds other thresholds.

[0045] This section describes the receipt printed by the printing device 18. Figure 5 shows an example of a receipt printed by a POS terminal according to this embodiment. Figure 5 shows receipt P. Receipt P includes regions RF, RG, and RH.

[0046] Area RF includes information such as the name and price of the purchased goods. Area RG includes information related to cash payments. Area RG includes information such as the total amount, amount received, change, and refunds. The amount received shows the total amount deposited by the customer. The change shows the amount obtained by subtracting the amount of deposits that can be accepted from the total amount. The refund shows the amount obtained by subtracting the amount of deposits that can be accepted from the deposit amount. For example, let's consider a case where the total amount is 9,720 yen and the total amount deposited by the customer is 11,125 yen. In this example, the customer deposits 21 5-yen coins, which is more than the threshold of 20 5-yen coins that can be accepted. In this case, 20 5-yen coins are accepted deposits, and 1 5-yen coin is an unacceptable deposit. Therefore, the amount of deposits that can be accepted is 11,120 yen, and the refund amount is calculated as "5 yen," which is the total amount minus the amount of deposits that can be accepted. In this example, the amount to be withdrawn is displayed in a way that allows identification of the amount to be withdrawn as change and the amount to be refunded because it cannot be accepted. The number of each denomination of coins to be refunded because it cannot be accepted may also be displayed in a way that allows identification. If one 5-yen coin is refunded, it may be displayed that one 5-yen coin is being refunded.

[0047] Area RH displays a warning message. The warning message may include a message informing the customer of the maximum number of coins that can be deposited. The warning message may include a message informing the customer that more coins than the maximum number of coins that can be deposited will be withdrawn. The warning message may include a message informing the customer that the number of coins deposited has exceeded a threshold. The warning message may include a message informing the customer that the number of coins deposited has exceeded another threshold. The warning message may include, for example, "Only 20 coins of the same denomination can be accepted in a single transaction," or "Any coins exceeding the maximum number that can be accepted will be refunded."

[0048] (Example of operation) Next, we will explain an example of the operation of POS terminal 1 configured as described above. The processing procedure described below is merely an example, and each process may be modified as much as possible. Furthermore, depending on the embodiment, steps in the processing procedure described below may be omitted, replaced, or added as appropriate.

[0049] This section describes an example where user X purchases goods at store A. Store A is the store that handles user X's transactions. Store A is set to accept 20 coins of each denomination in a single transaction. In this case, the threshold is 20 coins. Store A will also issue a warning message if the number of coins of each denomination inserted in a single transaction exceeds 14 and reaches 15. In this case, the other threshold smaller than the threshold is 14 coins. In this example, the number of coins deposited by user X will be counted.

[0050] User X registers one or more items as the subject of a transaction at store A using the scanner 15 of POS terminal 1. After registering each item of the transaction, User X inputs accounting instructions related to the transaction via the input device 16. The accounting instructions are instructions to start processing the transaction by the accounting processing unit 113. Here, User X selects cash payment as the payment method. User X selects cash payment and inserts cash into POS terminal 1. The following explanation will use the case where User X deposits coins as an example.

[0051] Figure 6 is a flowchart illustrating an example of the accounting processing procedure performed by the processor of the POS terminal 1 according to this embodiment. The counting unit 110 determines whether or not the user has deposited coins for payment in a commercial transaction (ACT1). If the counting unit 110 determines that the deposit has been made (ACT1:YES), the process transitions from ACT1 to ACT2. If the counting unit 110 determines that the deposit has not been made (ACT1:NO), the process transitions from ACT1 to ACT5.

[0052] The counting unit 110 counts the number of coins deposited by denomination based on the deposit of coins for payment in commercial transactions (ACT2). The counting unit 110 counts the number of coins deposited by denomination based on known technology.

[0053] The determination unit 115 determines whether the number of deposits of the same denomination counted by the counting unit 110 exceeds a threshold (ACT3). If the determination unit 115 determines that the number of deposits of the same denomination exceeds the threshold (ACT3: YES), the process transitions from ACT3 to ACT4. If the determination unit 115 determines that the number of deposits of the same denomination does not exceed the threshold (ACT3: NO), the process transitions from ACT3 to ACT5.

[0054] If the determination unit 115 determines that the number of coins of the same denomination deposited exceeds a threshold, the withdrawal control unit 111 controls the machine to withdraw the number of coins of the same denomination that exceeds the threshold (ACT4). For example, consider the case where user X deposits 21 5-yen coins. Based on the determination unit 115's determination that the number of 5-yen coins deposited exceeds the threshold of "20 coins", the withdrawal control unit 111 controls the machine to withdraw "1 coin" from the deposited 5-yen coins that exceeds the threshold. Based on the control by the withdrawal control unit 111, the change dispenser 13 dispenses the number of coins that exceeds the threshold. In this example, the change dispenser 13 dispenses 1 5-yen coin. The withdrawal control unit 111 controls the machine to withdraw the number of coins that exceeds the threshold each time the determination unit 115 determines that the number of deposited coins exceeds the threshold.

[0055] The accounting processing unit 113 determines whether or not an accounting instruction has been entered by the user (ACT5). For example, the accounting processing unit 113 determines whether or not an accounting instruction has been entered based on input from the user via the input device 16, such as an accounting instruction button. If the accounting processing unit 113 determines that an accounting instruction has been entered (ACT5:YES), the process transitions from ACT5 to ACT6. If the accounting processing unit 113 determines that no accounting instruction has been entered (ACT5:NO), the process returns from ACT5 to ACT1.

[0056] The accounting processing unit 113 processes the accounting for the commercial transaction based on the accounting instructions entered by the user (ACT6). The accounting processing unit 113 performs accounting based on known techniques. In this example, since user X has selected cash payment, it performs accounting based on cash payment.

[0057] The printing processing unit 114 controls the printing of the purchase receipt based on the accounting processing of the commercial transaction by the accounting processing unit 113 (ACT7). In ACT4, if a payment processing is performed by the payment control unit 111, the printing processing unit 114 may print the amount paid out because it exceeded a threshold on the purchase receipt. For example, in the above example, the printing processing unit 114 may print "5 yen" as the amount paid out. The printing processing unit 114 may also print the number of each denomination of coins paid out. For example, in the above example, the printing processing unit 114 may print "1" as the number of 5 yen coins paid out.

[0058] The accounting processing unit 113 determines whether or not there is change based on the accounting processing for cash payment (ACT8). If the accounting processing unit 113 determines that there is change (ACT8:YES), the process transitions from ACT8 to ACT9. If the accounting processing unit 113 determines that there is no change (ACT8:NO), the process terminates.

[0059] The dispensing control unit 111 controls the dispensing of change if the accounting processing unit 113 determines that there is change to be dispensed (ACT9). In ACT9, for example, based on the control by the dispensing control unit 111, the change dispenser 13 dispenses the change.

[0060] The withdrawal control unit 111 performs a cancellation process based on the user's input of a payment cancellation instruction. The determination unit 115 determines whether or not the user has input a payment cancellation instruction. Based on the determination unit 115's determination that a cancellation instruction has been input, the withdrawal control unit 111 controls the withdrawal to withdraw an amount equivalent to the deposited coins. In this case, the withdrawal control unit 111 may control the withdrawal to be in the same configuration as the number of coins of each denomination deposited. For example, if user X deposits 10 one-yen coins and 10 five-yen coins and then inputs a cancellation instruction, the withdrawal control unit 111 may withdraw the amount "60 yen" deposited with 10 one-yen coins and 10 five-yen coins.

[0061] Figure 7 is a flowchart illustrating another example of the accounting processing procedure performed by the processor of the POS terminal 1 according to this embodiment. In this example, if the determination unit 115 determines that the number of coins of the same denomination deposited exceeds a threshold, the withdrawal control unit 111 controls the withdrawal of the coins exceeding the threshold after the settlement processing of the commercial transaction.

[0062] The counting unit 110, similar to ACT1, determines whether or not the user has deposited coins for payment in a commercial transaction (ACT11). If the counting unit 110 determines that the deposit has been made (ACT11: YES), the process transitions from ACT11 to ACT12. If the counting unit 110 determines that the deposit has not been made (ACT11: NO), the process transitions from ACT11 to ACT15.

[0063] The counting unit 110, similar to ACT2, counts the number of coins deposited by denomination based on the deposit of coins for payment in commercial transactions (ACT12).

[0064] The determination unit 115, similar to ACT3, determines whether the number of deposits of the same denomination counted by the counting unit 110 exceeds a threshold (ACT13). If the determination unit 115 determines that the number of deposits of the same denomination exceeds the threshold (ACT13: YES), the process transitions from ACT13 to ACT14. If the determination unit 115 determines that the number of deposits of the same denomination does not exceed the threshold (ACT13: NO), the process transitions from ACT13 to ACT15.

[0065] If the determination unit 115 determines that the number of coins deposited of the same denomination exceeds a threshold, the withdrawal control unit 111 performs an overflow process (ACT 14). In ACT 14, for example, the withdrawal control unit 111 stores the number of coins exceeding the threshold for each denomination in an auxiliary storage device. For example, let's consider the case where user X deposits 21 five-yen coins. The determination unit 115 determines that the number of five-yen coins deposited exceeds the threshold of "20 coins". Based on the determination of the determination unit 115, the withdrawal control unit 111 stores the number of five-yen coins that exceeded the threshold, "1 coin," as the overflow withdrawal amount. For example, if user X deposits a number of coins exceeding the threshold for multiple denominations, the number of coins exceeding the threshold for each denomination may be stored as the overflow withdrawal amount. Specifically, let's consider the case where user X deposits 25 one-yen coins and 21 five-yen coins. The withdrawal control unit 111 stores five 1-yen coins and one 5-yen coin as the overflow withdrawal amount "10 yen". The withdrawal control unit 111 may store the overflow withdrawal amount as the number of coins of each denomination that make up the deposited coins, or it may store the overflow withdrawal amount regardless of the number of coins of each denomination.

[0066] The accounting processing unit 113, similar to ACT5, determines whether or not an accounting instruction has been entered by the user (ACT15). If the accounting processing unit 113 determines that an accounting instruction has been entered (ACT15: YES), the process transitions from ACT15 to ACT16. If the accounting processing unit 113 determines that no accounting instruction has been entered (ACT15: NO), the process returns from ACT15 to ACT11.

[0067] The accounting processing unit 113 processes the accounting of commercial transactions based on the user's input of accounting instructions, similar to ACT6 (ACT16).

[0068] The printing processing unit 114 controls the printing of the purchase receipt (ACT17) based on the accounting processing of the commercial transaction by the accounting processing unit 113, similar to ACT7. In ACT14, if the disbursement control unit 111 performs an overflow, the printing processing unit 114 may print the amount exceeding the threshold on the purchase receipt. For example, if user X inserts 21 five-yen coins, the printing processing unit 114 may print "5 yen" as the overflow disbursement amount. For example, if user X inserts 25 one-yen coins and 21 five-yen coins, the printing processing unit 114 may print "10 yen" as the overflow disbursement amount, or it may print the number of coins of each denomination that exceeded the threshold, such as "5 one-yen coins and 1 five-yen coin". If there is change, the printing processing unit 114 may print the overflow disbursement amount in a manner that can be identified as change.

[0069] The withdrawal control unit 111 determines whether a withdrawal is necessary (ACT18). In one example, the withdrawal control unit 111 determines whether there is change based on the accounting process for cash settlement. In another example, the withdrawal control unit 111 determines whether there is an overflow withdrawal amount based on overflow processing. In yet another example, the withdrawal control unit 111 determines whether a withdrawal is necessary based on the accounting process or overflow processing. If the withdrawal control unit 111 determines that a withdrawal is necessary (ACT18: YES), the process transitions from ACT18 to ACT19. If the withdrawal control unit 111 determines that a withdrawal is not necessary (ACT18: NO), the process terminates.

[0070] If the withdrawal control unit 111 determines that a withdrawal is necessary, the withdrawal control unit 111 controls the machine to withdraw an amount equivalent to the withdrawal amount (ACT 19). In ACT 19, for example, based on the control by the withdrawal control unit 111, the change dispenser 13 withdraws an amount equivalent to the withdrawal amount. In one example, the withdrawal control unit 111 controls the machine to withdraw the change. In another example, the withdrawal control unit 111 controls the machine to withdraw the overflow withdrawal amount. In yet another example, the withdrawal control unit 111 controls the machine to withdraw both the change and the overflow withdrawal amount. In this example, the withdrawal control unit 111 may withdraw the overflow withdrawal amount in the number of coins of each denomination that make up the deposit amount exceeding the threshold. The withdrawal control unit 111 may withdraw the overflow withdrawal amount regardless of the number of coins of each denomination that make up the deposit amount exceeding the threshold. For example, if user X inserts 25 1-yen coins and 21 5-yen coins, the withdrawal control unit 111 may withdraw an overflow withdrawal amount consisting of 5 1-yen coins and 1 5-yen coin. The withdrawal control unit 111 may also withdraw the overflow withdrawal amount of "10 yen" regardless of the number of coins of each denomination that make up the deposit amount that exceeds the threshold.

[0071] The withdrawal control unit 111 performs a cancellation process based on the user's input of a payment cancellation instruction. The determination unit 115 determines whether or not the user has input a payment cancellation instruction. Based on the determination unit 115's determination that a cancellation instruction has been input, the withdrawal control unit 111 controls the withdrawal to withdraw an amount equivalent to the deposited coins. In this case, the withdrawal control unit 111 may control the withdrawal to be in the same configuration as the number of coins of each denomination deposited. For example, if user X deposits 10 one-yen coins and 10 five-yen coins and then inputs a cancellation instruction, the withdrawal control unit 111 may withdraw the amount "60 yen" deposited with 10 one-yen coins and 10 five-yen coins.

[0072] Figure 8 is a flowchart illustrating an example of the processing procedure associated with display by the processor of the POS terminal 1 according to this embodiment. This example shows the screen transitions when user X continues to deposit money even after exceeding other thresholds that are smaller than the threshold value. The withdrawal control unit 111 controls the withdrawal of the number of coins that exceeded the threshold each time the determination unit 115 determines that the number of deposited coins has exceeded the threshold.

[0073] The counting unit 110, similar to ACT1, determines whether or not the user has deposited coins for payment in a commercial transaction (ACT111). If the counting unit 110 determines that the deposit has been made (ACT111: YES), the process transitions from ACT111 to ACT112. If the counting unit 110 determines that the deposit has not been made (ACT111: NO), the process repeats ACT111.

[0074] The counting unit 110, similar to ACT2, counts the number of coins deposited by denomination based on the deposit of coins for payment in commercial transactions (ACT112).

[0075] The determination unit 115 determines whether the number of deposits of the same denomination counted by the counting unit 110 exceeds a threshold value smaller than the threshold value (ACT113). If the determination unit 115 determines that the number of deposits of the same denomination has exceeded the threshold value (ACT113: YES), the process transitions from ACT113 to ACT114. If the determination unit 115 determines that the number of deposits of the same denomination has not exceeded the threshold value (ACT113: NO), the process returns from ACT113 to ACT111.

[0076] The display control unit 112 controls the display device 17 to display a message regarding the other threshold if the number of coins of the same denomination counted by the counting unit 110 exceeds a value smaller than the threshold of the other threshold (ACT 114). The display control unit 112 may also display a warning message on the display device 17 indicating that the other threshold has been exceeded. The display control unit 112 may also display information related to the deposited coins on the display device 17. For example, the display control unit 112 may display the number of coins of each denomination, the remaining number, etc., on the display device 17 in an identifiable manner. In one example, as shown in Figure 2, the display control unit 112 may display an area on the display device 17 that includes a denomination column, a number column, and a remaining number column. In another example, as shown in Figure 3, the display control unit 112 may display the number of coins deposited for each denomination on the display device 17 using an indicator.

[0077] The counting unit 110, similar to ACT111, determines whether or not the user has deposited coins for payment in a commercial transaction (ACT115). If the counting unit 110 determines that the deposit has been made (ACT115: YES), the process transitions from ACT115 to ACT116. If the counting unit 110 determines that the deposit has not been made (ACT115: NO), the process repeats ACT115.

[0078] The counting unit 110, similar to ACT 112, counts the number of coins deposited by denomination based on the deposit of coins for payment in commercial transactions (ACT 116).

[0079] The determination unit 115 determines whether the number of deposits of the same denomination counted by the counting unit 110 exceeds a threshold (ACT117). If the determination unit 115 determines that the number of deposits of the same denomination exceeds the threshold (ACT117: YES), the process transitions from ACT117 to ACT118. If the determination unit 115 determines that the number of deposits of the same denomination does not exceed the threshold (ACT117: NO), the process returns from ACT117 to ACT115.

[0080] The display control unit 112 controls the display device 17 to display a message regarding the threshold when the number of coins deposited in the same denomination, as counted by the counting unit 110, exceeds a threshold (ACT 118). The display control unit 112 may also display a warning message on the display device 17 indicating that the threshold has been exceeded. In this case, the withdrawal control unit 111 withdraws the number of coins deposited in each denomination that exceeds the threshold.

[0081] Figure 9 is a flowchart illustrating another example of the processing procedure associated with display by the processor of the POS terminal 1 according to the embodiment.

[0082] In this example, if the determination unit 115 determines that the number of coins of the same denomination deposited exceeds a threshold, the withdrawal control unit 111 controls the withdrawal of the coins exceeding the threshold after the settlement processing of the commercial transaction.

[0083] The counting unit 110, similar to ACT111, determines whether or not the user has deposited coins for payment in a commercial transaction (ACT211). If the counting unit 110 determines that the deposit has been made (ACT211: YES), the process transitions from ACT211 to ACT212. If the counting unit 110 determines that the deposit has not been made (ACT211: NO), the process repeats ACT211.

[0084] The counting unit 110, similar to ACT 112, counts the number of coins deposited by denomination based on the deposit of coins for payment in commercial transactions (ACT 212).

[0085] The determination unit 115, similar to ACT113, determines whether the number of deposits of the same denomination counted by the counting unit 110 exceeds another threshold value that is smaller than the threshold value (ACT213). If the determination unit 115 determines that the number of deposits of the same denomination exceeds another threshold (ACT213: YES), the process transitions from ACT213 to ACT214. If it determines that the number of deposits of the same denomination does not exceed another threshold (ACT213: NO), the process returns from ACT213 to ACT211.

[0086] The display control unit 112 controls the display device 17 to display a message regarding other thresholds if the number of coins of the same denomination counted by the counting unit 110 exceeds a value smaller than the threshold value of other thresholds (ACT214). The display control unit 112 may also display a warning message on the display device 17 indicating that other thresholds have been exceeded. The display control unit 112 may also display information related to the deposited coins on the display device 17. For example, the display control unit 112 may display the number of coins of each denomination, the remaining number, etc., on the display device 17 in an identifiable manner. In one example, as shown in Figure 2, the display control unit 112 may display an area on the display device 17 that includes a denomination column, a number column, and a remaining number column. In another example, as shown in Figure 3, the display control unit 112 may display the number of coins deposited for each denomination on the display device 17 using indicators.

[0087] The counting unit 110, similar to ACT211, determines whether or not the user has deposited coins for payment in a commercial transaction (ACT215). If the counting unit 110 determines that the deposit has been made (ACT215: YES), the process transitions from ACT215 to ACT216. If the counting unit 110 determines that the deposit has not been made (ACT215: NO), the process repeats ACT215.

[0088] The counting unit 110, similar to ACT212, counts the number of coins deposited by denomination based on the deposit of coins for payment in commercial transactions (ACT216).

[0089] The determination unit 115 determines whether the number of deposits of the same denomination counted by the counting unit 110 exceeds a threshold (ACT217). If the determination unit 115 determines that the number of deposits of the same denomination exceeds the threshold (ACT217: YES), the process transitions from ACT217 to ACT218. If the determination unit 115 determines that the number of deposits of the same denomination does not exceed the threshold (ACT217: NO), the process returns from ACT217 to ACT215.

[0090] The display control unit 112 controls the display device 17 to display a message regarding the threshold when the number of deposits of the same denomination counted by the counting unit 110 exceeds the threshold (ACT218). The display control unit 112 may also display a warning message indicating that the threshold has been exceeded on the display device 17.

[0091] The counting unit 110, similar to ACT211, determines whether or not the user has deposited coins for payment in a commercial transaction (ACT219). If the counting unit 110 determines that the deposit has been made (ACT219: YES), the process transitions from ACT219 to ACT220. If the counting unit 110 determines that the deposit has not been made (ACT219: NO), the process repeats ACT219.

[0092] The counting unit 110, similar to ACT212, counts the number of coins deposited by denomination based on the deposit of coins for payment in commercial transactions (ACT220). In this case, the display control unit 112 may display the number of coins deposited by denomination on the display device 17 based on the number of coins of the same denomination counted by the counting unit 110.

[0093] The accounting processing unit 113, similar to ACT5, determines whether or not an accounting instruction has been entered by the user (ACT221). If the accounting processing unit 113 determines that an accounting instruction has been entered (ACT221: YES), the process transitions from ACT221 to ACT222. If the accounting processing unit 113 determines that no accounting instruction has been entered (ACT221: NO), the process returns from ACT221 to ACT219.

[0094] The display control unit 112 controls the display device 17 to display the number of coins to be dispensed in a manner that can be identified as a dispensing based on the settlement process of a commercial transaction (ACT222). In ACT222, for example, the display control unit 112 may control the display device 17 to display the change based on the accounting processing by the accounting processing unit 113 and the number of coins exceeding a threshold by denomination. The number of coins exceeding a threshold indicates the coins to be dispensed. The number of coins exceeding a threshold corresponds to the overflow dispensing amount. For example, if user X inserts 25 1-yen coins and 21 5-yen coins, the display control unit 112 may display the number of coins exceeding a threshold by denomination, such as "5 1-yen coins, 1 5-yen coin," on the display device 17. If there is change, the display control unit 112 may display the overflow dispensing amount on the display device 17 in a manner that can be identified as change.

[0095] In the flowcharts shown in Figures 6 to 9, if user X inputs a termination command, the processor 10 terminates the process. For example, the determination unit 115 determines whether or not user X has input a termination command. If the determination unit 115 determines that a termination command has been input, the process terminates.

[0096] (effect) The accounting device according to the embodiment can count the number of coins deposited by denomination based on the deposit of coins for payment of commercial transactions, and if the counted number of coins of the same denomination exceeds a threshold for the number of coins that can be accepted in a single commercial transaction, it can control the device to withdraw the number of coins of the same denomination that exceeds the threshold. This allows the accounting system to dispense coins exceeding a certain threshold if a customer inserts more than that number of coins of the same denomination. Therefore, it can prevent customers from inserting large quantities of coins of the same denomination. In this way, the accounting system can limit the number of coins of the same denomination that a customer can deposit. Furthermore, the accounting system can prevent malfunctions such as jams caused by customers inserting large quantities of coins.

[0097] The accounting device according to this embodiment can display a message on the display unit regarding other thresholds if the number of coins deposited of the same denomination exceeds a value smaller than one threshold. This allows the accounting device to notify the customer of the number of coins that can be deposited and to warn the customer before the number of coins that can be deposited is reached. Therefore, it is possible to prevent customers from depositing large quantities of coins of the same denomination in advance. In this way, the accounting device can limit the number of coins of the same denomination that a customer can deposit.

[0098] The accounting device according to this embodiment can dispense coins exceeding a threshold after the settlement process of a commercial transaction. This eliminates the need for the accounting device to dispense coins exceeding the threshold each time the threshold is exceeded. Therefore, the accounting device can simplify overflow handling when more coins than the threshold are inserted. In addition, customers can receive their winnings all at once during the accounting process, thus improving convenience.

[0099] The accounting device according to this embodiment can display the number of coins to be dispensed in a manner that can be identified as a dispensing based on the settlement process of a commercial transaction. This allows the accounting device to distinguish the number of coins dispensed that exceeds a threshold from the number of coins dispensed as change. Therefore, customers can easily recognize whether the dispensed coins exceed a threshold or are change. In this way, the accounting device can improve customer convenience by making the dispensed coins identifiable.

[0100] The accounting device according to this embodiment can withdraw coins in the same configuration as the number of coins of each denomination deposited, based on the input of a payment cancellation instruction. This allows the accounting device to prevent, for example, a customer from exchanging lower-denomination coins for higher-denomination coins. Therefore, the accounting device can limit the number of coins of the same denomination deposited by a customer.

[0101] The accounting device according to this embodiment can switch threshold settings in accordance with the switching of transaction modes. This allows the accounting device to switch threshold settings according to the store's operations. Therefore, the accounting device can improve convenience for the store. In addition, the accounting device can change or clear the threshold settings in maintenance modes such as when replenishing deposits of rolls of cash. Therefore, the accounting device can change the limit on the number of coins of the same denomination that can be deposited according to the transaction mode.

[0102] [Other embodiments] In the above embodiment, the counting unit 110 counts the number of coins deposited by denomination based on the deposit of coins by the customer for payment of a commercial transaction, and the dispensing control unit 111 controls the dispensing of the number of coins of the same denomination that exceeds the threshold when the number of coins of the same denomination counted by the counting unit 110 exceeds the threshold. However, the embodiment is not limited to this. The dispensing control unit 111 may switch the threshold setting according to the switching of transaction modes. For example, in the normal transaction mode in which a store clerk deposits coins for processing a commercial transaction, and in the face-to-face transaction mode in which it operates as a face-to-face POS terminal used in a manner in which a store clerk and a customer face to face, the threshold may be set or not set as desired. In the maintenance mode in which a store clerk replenishes the coins in the accounting device, the threshold may be switched to a higher value. For example, in maintenance mode, the threshold may be set to 50 coins.

[0103] In the above embodiment, the accounting device showed a method of dispensing coins exceeding a threshold after the settlement of a commercial transaction, as one example of a dispensing method. As a variation of this, the dispensing control unit 111 can control the dispensing method so that the change and the coins exceeding the threshold are dispensed together at the same time. In this case, the time required for operation can be reduced because the change and the coins exceeding the threshold are dispensed all at once. Alternatively, the dispensing control unit 111 can dispense the change first, and after a sensor in the change dispenser detects that the customer has taken the change, it can then dispense the coins exceeding the threshold. In this case, by clearly separating the dispensing of change from the dispensing of coins exceeding the threshold, it is possible to inform the customer of the difference between the change and the overflow amount along with the display on the display device 17.

[0104] In another embodiment, the accounting device may be equipped with a coin selector, which is a mechanism for identifying inserted coins, downstream of the deposit slot of the change dispenser 13 of the accounting device. When the processor 10 of the accounting device receives more coins than a threshold, it notifies the coin selector of the denominations that exceed the threshold. When the coin selector receives the information of the denominations from the processor 10, and detects that the coins deposited from the deposit slot include coins of a denomination that exceed the threshold, it performs a process (rejection process) to forcibly eject these coins to the outside of the accounting device (for example, to the dispensing slot). As a result, coins that exceed the threshold can be ejected to the outside by the coin selector before they are counted by the counting unit. Therefore, consumers can immediately understand that coins exceeding the threshold cannot be deposited at the time they are making a deposit.

[0105] The trading mode may also be switched based on key operations, as shown in Figure 10. For example, to switch to maintenance mode, set key K to "maintenance". To switch to registration mode to register products, set key to "register". The determination unit 115 determines whether the number of deposits of the same denomination counted by the count unit 110 exceeds the threshold set for each trading mode.

[0106] In the above embodiment, an example was described in which the display control unit 112 controls the display device 17 to display a warning message and information related to the deposited coins, but the system is not limited to this. For example, the warning message and information related to the deposited coins may be displayed on a display provided separately from the display device 17. Alternatively, notification may be provided by means other than display, such as audio output.

[0107] POS terminal 1 is not limited to self-service POS terminals. It may also be a regular POS terminal operated by a store employee. Furthermore, it may be a semi-self-service POS terminal in which a registration device for registering products and a payment device for processing payments based on the registered product information are separated, with the registration device operated by a store employee and the payment device operated by the customer.

[0108] The change dispenser 13 may separate banknotes and coins. That is, the accounting device may be equipped with an automatic change dispenser for coins only, which notifies the number of coins of each denomination inserted. Similarly, the accounting device may be equipped with an automatic change dispenser for banknotes, which notifies the number of banknotes of each denomination inserted.

[0109] The accounting device may be implemented as a single electronic device, as explained using POS terminal 1 as an example, or it may be implemented as a system in which the functions are distributed among multiple electronic devices.

[0110] The program may be transferred while stored on an electronic device, or it may be transferred without being stored on an electronic device. In the latter case, the program may be transferred via a network, or it may be transferred while recorded on a recording medium. The recording medium is a non-temporary tangible medium. The recording medium is an electronic device-readable medium. The recording medium can be any medium that is capable of storing a program and readable by an electronic device, such as a CD-ROM or memory card, and its form is not limited.

[0111] In addition, several embodiments of the present invention have been described, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be carried out in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of symbols]
