The LAN interface 231 enables data communication with the store computer 281 via the LAN cable 291 (see FIG. 1). The connection interface 234 is connected to the connection interface 273 of the automatic change machine 241 via the communication cable 234a. That is, data communication with the automatic change machine 241 is enabled via the communication cable 234a. Various files such as an operation program, a PLU file, an image file, an audio file, and a sales file are stored and stored in the HDD 232. All or a part of these operation programs and various files are transferred to the RAM 224 and used when the POS terminal 211 is activated. The PLU file stores the unit price and the like in a rewritable manner in association with the product code for specifying each product. The PLU file is distributed from the store computer 281 (see FIG. 1) and stored in the HDD 232.

  The control unit 221 of the POS terminal 211 configured as described above executes merchandise sales data processing including search processing and settlement processing.

  When the barcode attached to the product is read using the barcode scanner 219, the search process recognizes the product code specified by the read barcode, searches the PLU file, and corresponds to the product code. It is a process which acquires the unit price to perform, weight, and a product display.

  The payment process is a process of calculating the total amount that the customer should pay based on the unit price acquired in the search process, and executing the payment of the total amount. The total amount is provisionally registered in the RAM 224 or registered in the sales file. In the settlement process, a deposit amount from the customer is received by pressing the numeric keypad on the keyboard 213, and a change amount is obtained based on the total amount and the deposit amount.

  Further, the control unit 221 of the POS terminal 211 forms a time-series stock file F2 (see FIG. 9). The time series stock file F2 is formed in, for example, the RAM 224 and stored and saved in the HDD 232.

  Next, a hardware configuration of the automatic change machine 241 connected to the POS terminal 211 so as to be able to perform data communication will be described.

  As shown in FIG. 4, the automatic change machine 241 includes a control unit 261 that drives and controls each unit. The control unit 261 functions as a work area or the like by storing a ROM 263 that preliminarily stores fixed data such as a control program and the like in a CPU 262 that centrally controls each unit, and a variety of data in a rewritable manner via a bus line 274. RAM 264 to be connected is configured. Therefore, the control unit 261 constitutes an information processing unit that executes information processing. A part of the RAM 264 is a non-volatile memory in which stored contents are not lost even when the automatic change machine 241 is turned off. In the RAM 264, there is formed a cash amount file F1 (see FIG. 5) that stores the amount of money stored in the coin storage portion 253 (see FIG. 3) and the bill storage portion 257 (see FIG. 3).

  The controller 261 includes a motor controller 266 to which motors 265 are connected, a solenoid controller 272 to which solenoids 271 are connected, a sensor controller 270 to which sensors 267 including a deposit sensor 268 and a withdrawal sensor 269 are connected, A connection interface 273 is connected via the bus line 274.

  The motor controller 266 drives and controls the motors 265 to rotate the motors 265. The motors 265 are drive sources that rotate a conveyor belt (not shown) provided inside the automatic change machine 241. The conveyor belt is provided in the coin depositing unit 251, the coin dispensing unit 254, the banknote depositing unit 255, the banknote dispensing unit 258, and the like, and deposits / withdraws money to / from the automatic change machine 241 by rotation thereof. The solenoid controller 272 drives and controls the solenoids 271 to displace the solenoids 271. The solenoids 271 are provided in the coin dispensing unit 254 and pay out the designated number of coins. The sensor controller 270 takes the detection output of the sensors 267 into the control unit 261. The connection interface 273 is connected to the connection interface 234 of the POS terminal 211 via the communication cable 234a. That is, data communication with the POS terminal 211 is enabled via the communication cable 234a.

  The control unit 261 of the automatic change machine 241 configured in this way specifies the denomination of the deposited money based on the detection output of the deposit sensor 268. In addition, the control unit 261 of the automatic change machine 241 specifies the denomination of the withdrawal money based on the detection output of the withdrawal sensor 269. Since the contents of the processing procedure for specifying the denomination are well known, the description thereof is omitted.

  FIG. 5 is a schematic diagram showing the data structure of the cash file F1. The cash balance file F1 has a data structure capable of storing the “bank balance” for each “denomination” of money. “Raw data” stores “raw data” and “correction data”. Details of “raw data” and “correction data” will be described with reference to FIG.

  FIG. 6 is a flowchart showing the flow of processing at the time of shifting to the replenishment collection mode and canceling the shift. The control unit 221 of the POS terminal 211 waits for pressing of the replenishment collection key 213a included in the keyboard 213 of the POS terminal 211 (step S101). When replenishing money to the automatic change machine 241 or collecting money from the automatic change machine 241, the store clerk or the like presses the replenishment collection key 213 a. If the replenishment / recovery key 213a is pressed (Y in step S101), the control unit 221 of the POS terminal 211 receives money from the customer other than the deposit from the customer with respect to the connected automatic change machine 241. An instruction to shift to the replenishment / collection mode for dispensing money other than change is transmitted (step S102). The replenishment collection mode is a mode for replenishing and collecting money.

  When the control unit 261 of the automatic change machine 241 receives an instruction to shift to the replenishment / collection mode (Y in step S107), the control unit 261 proceeds to the replenishment / collection mode (step S108). The processing executed by the automatic change machine 241 when depositing or withdrawing in the state of shifting to the replenishment collection mode will be described based on the flowchart of FIG.

  Next, the control unit 221 of the POS terminal 211 waits for the press of the supplement collection key 213a again (step S103). If the replenishment / collection key 213a is pressed (Y in step S103), a release instruction for canceling the transition to the replenishment / recovery mode is transmitted to the automatic change machine 241 (step S104). If the control unit 261 of the automatic change machine 241 receives the cancel instruction (Y in step S109), the control unit 261 cancels the transition to the replenishment collection mode (step S110).

  Then, the control unit 261 of the automatic change machine 241 stores the “raw data” and “correction data” of the “cash balance” for each denomination stored in the cash balance file F1 (see FIG. 5) in the POS terminal 211. It transmits to (step S111). When the control unit 221 of the POS terminal 211 receives the data on the bank balance (Y in step S105), the control unit 221 stores the data in the time series bank file F2 (see FIG. 9) formed in the RAM 224 of the POS terminal 211. (Step S106).

  FIG. 7 is a flowchart showing a flow of processing when adding the stocks in the stock file F1. If there is a detection output of the deposit sensor 268 (Y in step S201), the control unit 261 of the automatic change machine 241 specifies the denomination based on the detection output (step S202). Then, it is determined whether or not the mode is shifted to the replenishment / collection mode (step S203). If the mode has not shifted to the replenishment / recovery mode (N in step S203), the control unit 261 of the automatic change machine 241 determines the “raw data” and “correction data” of the “stock balance” of the stock file F1 for the specified denomination "1" is added to both "" (step S205). On the other hand, if the mode has shifted to the replenishment / recovery mode (Y in step S203), the control unit 261 of the automatic change machine 241 determines “raw data” of “stock” in the cash file F1 for the specified denomination. “1” is added to only (step S204).

  Note that the same processing is executed when subtracting the “stock” of the stock file F1. That is, if there is a detection output of the withdrawal sensor 269, the control unit 261 of the automatic change machine 241 specifies the denomination based on the detection output. Then, it is determined whether or not the mode is shifted to the replenishment collection mode. If the mode has not been changed to the replenishment / collection mode, the control unit 261 of the automatic change machine 241 determines the “determined money” from both “raw data” and “correction data” of the “stock balance” of the stock file F1. 1 "is subtracted. On the other hand, if the mode has been shifted to the replenishment / collection mode, the control unit 261 of the automatic change machine 241 changes “1” from only the “raw data” of the “stock amount” of the stock file F1 for the specified denomination. Subtract.

  In other words, the “correction data” of “stock balance” of the stock file F1 shown in FIG. 5 stores the number obtained by subtracting the number of coins deposited in the state of transition to the supplement collection mode. The stock amount obtained by adding the number of coins withdrawn in the state transferred to is stored. On the other hand, the “raw data” stores a stock amount that reflects the deposits and withdrawals in the state of shifting to the replenishment collection mode.

  The replenishment / recovery key 213a is also pressed when the automatic change machine 241 exchanges money. For example, there is a case in which one 5000-yen banknote is to be exchanged for 5 1000-yen banknotes for one automatic change machine 241. In this case, one 5000 yen banknote is dispensed from the automatic change machine 241. Then, the dispensed 5000 yen banknote is deposited into another automatic change machine 241 and the automatic change machine 241 causes 5 1000 yen banknotes to be dispensed. Next, the five 1000 yen bills are deposited into the automatic change machine 241 from which the 5000 yen bills were withdrawn. During this time, the two automatic change machines 241 are in the replenishment collection mode when the replenishment collection key 213a is pressed.

  FIG. 8 is a flowchart showing a flow of processing executed in the settlement processing. As described above, the control unit 221 of the POS terminal 211 obtains a change amount in the settlement process. The control unit 221 of the POS terminal 211 transmits a payout instruction for the calculated change amount to the automatic change machine 241 (step S301). When the control unit 261 of the automatic change machine 241 receives a payout instruction from the POS terminal 211 (Y in step S304), it controls the motors 265 and the solenoids 271 to pay out money based on the received payout instruction. Is executed (step S305).

  Next, the control unit 261 of the automatic change machine 241 waits for the elapse of a predetermined time (step S306). During this time, the cashier deposits the money deposited from the customer into the automatic change machine 241. If the predetermined time has elapsed (Y in step S306), the balance data for each denomination stored in the balance file F1 is transmitted to the POS terminal 211 (step S307).

  Here, in the settlement process, in the cash file F1, the “cash amount” of the cash file F1 increases or decreases due to the withdrawal of the change amount and the deposit amount.

  In addition, since it has not shifted to the replenishment collection mode, the “raw data” of the cash file F1 has the same increase / decrease in its “raw data” and “correction data”.

  The control unit 221 of the POS terminal 211 stores the received balance data in the time-series balance file F2 (see FIG. 9) formed in the RAM 224 of the POS terminal 211 (step S303). Here, a means is realized in which the control unit 221 that is an information processing unit stores the calculated stock in the RAM 224 that is a storage area for each transaction.

  FIG. 9 is a schematic diagram showing the data structure of the time series stock file F2. The time-series cash file F2 has a data structure capable of storing raw cash data and correction data received from the automatic change machine 241 each time it is received. Further, the time series stock file F2 is provided for each denomination. When the control unit 221 of the POS terminal 211 receives the cash amount data from the automatic change machine 241, the control unit 221 sequentially stores the cash amount in the time-series cash file F <b> 2. That is, the time-series stock file F2 constitutes a storage area in which the found stock is stored for each transaction. At this time, the control unit 221 of the POS terminal 211 stores the data of “revenue” from the opening of the store 201 to the closing of the store 201 in the time-series surplus file F2.

  FIG. 10 is a flowchart showing the flow of processing when obtaining a change reserve. When the change reserve calculation key 213b of the keyboard 213 is pressed (Y in step S401), the control unit 221 of the POS terminal 211 executes a process for obtaining a change reserve for the denomination (step S402). In step S402, the difference between the maximum value and the minimum value of the “correction data” of “stock” for each denomination stored in the time series stock file F2 is obtained as a change reserve. As described above, the amount of money in the correction data is the amount of money in which the number of coins deposited in the replenishment collection mode is subtracted and the number of coins in the replenishment collection mode is added.

  FIG. 11 is a graph showing a time-series change in cash. That is, the graph shown in FIG. 11 is a plot of the data on the amount of money from opening to closing stored in the time-series cash amount file F2 in the order received by the POS terminal 211. In FIG. 11, black circles are plots of “raw data”, and hollow squares are plots of “correction data”.

  Fig.11 (a) is a graph shown about the amount of money of a 10 yen coin. The stock amount that was 100 at the time of opening (arrow A1) is gradually decreasing. If such a decrease in stock continues, change will be insufficient. Therefore, the automatic change machine 241 is shifted to the replenishment collection mode, and 20 10-yen coins are deposited (arrow A2). When the raw data plot in the arrow A2 is seen, the stock amount has increased by 20 sheets, while when the correction data plot is seen, the stock amount has not changed. In other words, the amount of money deposited in the state of shifting to the replenishment collection mode is subtracted from the correction data of the cash balance. The stock amount at the time of closing (arrow A3) is 84 sheets in the raw data reflecting the deposit and withdrawal in the supplementary collection mode, whereas the number of coins deposited in the supplementary collection mode is 84. In the correction data from which is subtracted, the number is 64, which is 20 less.

  From the graph of FIG. 11 (a), the maximum value of “correction data” for “revenue” for a 10-yen coin is “100 sheets” at the time of opening (arrow A1), and the minimum value is at the time of closing (arrow). It is “64 sheets” of A3). Therefore, 100 (sheets) -64 (sheets) is calculated as change reserve for 10 yen coins, and 36 sheets are obtained.

  FIG.11 (b) is a graph shown about the amount of money of a 50 yen coin. The stock amount that was 50 at the time of opening (arrow B1) is gradually increasing. Therefore, the automatic change machine 241 is shifted to the replenishment collection mode, and 20 50-yen coins are dispensed (arrow B2). When the raw data plot in the arrow B2 is seen, the stock amount has decreased by 20 sheets, whereas when the correction data plot is seen, the stock amount has not changed. That is, 20 correction data are added. The stock amount when the store is closed (arrow B4) is 39 sheets in the raw data, but 59 sheets in the correction data.

  From the graph of FIG. 11 (b), the maximum value of the “correction data” for the “revenue” for the 50 yen coin is “62” at the time of the arrow B3, and the minimum value is at the time of opening the store (arrow B1 ) "50". Therefore, 62 (sheets) -50 (sheets) is calculated as a change reserve for 50 yen coins, and 12 sheets are obtained.

  That is, as a change reserve for the next business day, 36 sheets for 10 yen coins and 12 sheets for 50 yen coins may be prepared and set. Thus, in the present embodiment, it is possible to obtain an appropriate change reserve without being based on experience.

  Returning to the flowchart of FIG. The control unit 221 of the POS terminal 211 causes the cashier display 215 to display the change reserve determined in step S402 (step S403). In step S403, the control unit 221 of the POS terminal 211 generates a change reserve display screen G (see FIG. 12) and displays it on the screen of the cashier display 215.

  FIG. 12 is a schematic diagram illustrating an example of the change reserve display screen G. The change reserve display screen G includes a change reserve display area G1 for displaying a change reserve corresponding to each denomination. In the change reserve display area G1, the change reserve obtained in step S402 of the flowchart of FIG. 10 is displayed.

  Furthermore, the change reserve display screen G has a plurality of event keys G2 on the right side of the screen. The event key G2 includes, for example, a key displayed as “Special Sale” and a key displayed as “Holiday”. When the touch panel 214 corresponding to the area where the event key G2 is displayed is touch-operated, the calculation previously associated with the event key G2 is performed on the change reserve displayed in the change reserve display area G1. Executed. For example, it is expected that more change reserves will be required on special sales days. Therefore, the calculation “+30” is associated with the event key G2 of “special sale date”. If the “Special Sale Day” event key G2 is touched, “30” is added to the change reserve displayed in the change reserve display area G1, and the added value is set as a new change. Displayed as a reserve in the change reserve display area G1. It goes without saying that the calculation associated with the event key G2 may be different for each denomination.

  Further, the change reserve display screen G has a graph display key G3 displayed as “graph” for each denomination adjacent to the change reserve display area G1. When the graph display key G <b> 3 is touched, a cash amount display screen H (see FIG. 13) having a graph showing a time-series change in money amount is displayed on the cashier display 215 for the corresponding denomination.

  FIG. 13 is a schematic diagram showing the cash amount display screen H. The cash amount display screen H has a cash amount graph H1. The stock amount graph H1 is a graph showing a time-series change of the stock amount from the opening time to the closing time for the denomination corresponding to the touched graph display key G3 (see FIG. 12). The stock amount graph H1 is based on the “raw data” and “correction data” stored in the time series stock file F2 (see FIG. 9). Further, the cash amount display screen H has a return key H2 on which “return” is displayed at a position below the cash amount graph H1. When the return key H2 is touched, the cash amount display screen H disappears, and the change reserve display screen G appears on the cashier display 215 again.

  Returning to the description of FIG. The change reserve display screen G has a print key G4 on which “print” is displayed below the event key G2. When the print key G4 is touched, the control unit 221 of the POS terminal 211 controls the printer 229 to print the change reserve displayed in the change reserve display area G1 together with the denomination on the receipt paper. Issue.

  In the present embodiment, the control unit 221 of the POS terminal 211 calculates the change reserve, but the control unit 261 of the automatic change machine 241 calculates the change reserve. Also good. In this case, the time series bank file F2 (see FIG. 9) is formed in the automatic change machine 241.

  Further, the change reserve may be obtained by a control unit (not shown) of the store computer 281 connected to the POS terminal 211. Further, the change reserve may be obtained by a control unit (not shown) of the host computer 311 connected to the store computer 281 or a control unit (not shown) of the security company computer 411.

  When the control unit of the store computer 281 determines the change reserve, the time-series cash amount file F2 (see FIG. 9) is formed in the store computer 281 for each automatic change machine 241. In this case, the control unit 221 of the POS terminal 211 that has received the cash amount data from the automatic change machine 241 in step S105 of the flowchart of FIG. 6 or step S302 of the flowchart of FIG. The high data is transmitted to the store computer 281. Then, the control unit of the store computer 281 sequentially stores the received balance data in the corresponding time-series balance file F2. The control unit of the store computer 281 obtains a change reserve based on the maximum value and the minimum value of the “correction data” of “balance” stored in the time series balance file F2.

  When the control unit of the host computer 311 obtains the change reserve, the time series stock file F2 (see FIG. 9) is formed in the host computer 311 for each automatic change machine 241. In this case, the control unit 221 of the POS terminal 211 that has received the cash amount data from the automatic change machine 241 in step S105 of the flowchart of FIG. 6 or step S302 of the flowchart of FIG. The high data is transmitted to the store computer 281. Then, the control unit of the store computer 281 further transmits the received cash amount data to the host computer 311 of the supervision unit 301 via the communication network 111. Then, the control unit of the host computer 311 sequentially stores the received cash amount data in the corresponding time-series cash file F2. The control unit of the host computer 311 obtains a change reserve based on the maximum value and the minimum value of the “correction data” of “stock amount” stored in the time series stock file F2.

  When the control unit of the security company computer 411 asks for a change reserve, the time series cash amount file F2 (see FIG. 9) is formed for each automatic change machine 241 in the security company computer 411. In this case, the control unit 221 of the POS terminal 211 that has received the cash amount data from the automatic change machine 241 in step S105 of the flowchart of FIG. 6 or step S302 of the flowchart of FIG. The high data is transmitted to the store computer 281. Then, the control unit of the store computer 281 further transmits the received balance data to the security company computer 411 of the security company 401 via the communication network 111. Then, the control unit of the security company computer 411 sequentially stores the received balance data in the corresponding time-series balance file F2. The control unit of the security company computer 411 obtains a change reserve based on the maximum value and the minimum value of the “correction data” of “stock” stored in the time series stock file F2. In this way, when the control unit of the security company computer 411 asks for a change reserve, the security company 401 prepares a change change necessary for each automatic change machine 241 and brings the prepared change reserve into the store 201. The operation of setting money in the automatic change machine 241 directly without going through the store clerk 201 can be executed. Such an operation is desirable from the viewpoint of crime prevention because cash is not handled at the store 201 when the change reserve is set.
