  Next, the operation of the merchandise sales data processing apparatus 1 configured as described above will be described.

  FIG. 2 is a flowchart of the CPU 101.

  In a state where the business mode is set to the registration mode, the CPU 101 waits for the PLU code to be input. In response to the input of the PLU code, the CPU 101 starts the process shown in FIG.

  In step Sa1, the CPU 101 performs product registration. This product registration is a process of inputting PLU codes and quantities of all products purchased by one customer and writing them in the product list area in the RAM 103. For product registration, the same type of processing performed in an existing product sales data processing apparatus can be applied as it is. If an operation for requesting execution of settlement is performed by the cashier, the CPU 101 proceeds to step Sa2.

  In step Sa2, the CPU 101 calculates the total amount based on the PLU code and quantity stored in the product list area and the unit price corresponding to the PLU code.

  In step Sa3, the CPU 101 determines a deposit amount. Specifically, the CPU 101 waits for the cashier to perform an operation for inputting the deposit amount on the operation device 107. If the cashier performs the corresponding operation, the CPU 101 determines the deposit amount based on the command output from the operation device 107. When the change machine 200 has a function of depositing a deposit, and the deposited money is inserted into the change machine 200 by the cashier, the CPU 201 calculates the deposit amount and sends information representing the deposit amount from the communication interface 206. Send. Therefore, in this case, the CPU 101 acquires the information transmitted by the communication interface 206 as described above via the communication interface 111, and determines the deposit amount based on this information.

  In step Sa4, the CPU 101 calculates the change amount by subtracting the total amount calculated in step Sa2 from the deposit amount determined in step Sa3.

  In step Sa <b> 5, the CPU 101 determines a combination of coins for paying out the calculated change amount from the change machine 200. For this determination, a known process can be applied as it is. In this determination, the CPU 101 determines the number of payouts for each of a plurality of types of coins. Thus, the CPU 101 has a function as a number determination unit.

  In step Sa6, the CPU 101 instructs the change machine 200 to pay out the determined combination of coins as change. Specifically, the CPU 101 transmits an issue instruction command including information representing the combination of coins determined in step Sa5 from the communication interface 111 to the change machine 200. This issuance instruction command is given from the communication interface 206 to the CPU 201. Then, the CPU 201 operates the motor group 207 and pays out coins in the designated combination. Thus, the CPU 101 has a function as a change machine control means.

  In step Sa7, the CPU 101 sets 1 to the variable N.

  In step Sa8, the CPU 101 confirms whether or not the combination determined in step Sa5 includes the Nth denomination among a plurality of denominations of coins used for change payout. If YES is determined here, the CPU 101 proceeds to step Sa9. In addition, if the coins used for the change are 500 yen, 100 yen, 50 yen, 10 yen, 5 yen, 1 yen, for example, 500 yen, 100 yen, 50 yen, 10 yen, 5 yen It is defined in advance such that the first to sixth denominations are set in the order of 1 yen.

  In step Sa <b> 9, the CPU 101 reads out the appearance data of the Nth denomination from the auxiliary storage device 104. For this reason, in the auxiliary storage device 104, appearance data representing the appearance images (hereinafter referred to as appearance images) of the coins of each denomination used for paying out change is written in advance. The CPU 101 temporarily stores the read appearance data in the RAM 103. That is, the auxiliary storage device 104 is an example of a storage medium. However, as the storage medium, the ROM 102 or the RAM 103 may be used, and various types of storage media existing outside the main unit 100 may be used.

  If it is determined NO in step Sa8, the CPU 101 passes step Sa9 and proceeds to step Sa10.

  In step Sa10, the CPU 101 increases the value of the variable N by one.

  In step Sa11, the CPU 101 confirms whether the variable N is equal to or greater than Nmax. Here, Nmax is the number of denominations of coins used to change money. That is, Nmax is 6 if the coin used for paying out the change is the above-mentioned 6 denominations. If the variable N is less than Nmax, the CPU 101 returns to step Sa8 and performs steps Sa8 to Sa11 again. Thus, the CPU 101 reads out each of the appearance data for the denominations included in the combination determined in step Sa <b> 5 and temporarily stores it in the RAM 103.

  If step Sa8 and step Sa10 have been executed for all denominations, the value of variable N matches Nmax. In this case, the CPU 101 proceeds from step Sa11 to step Sa12.

  In step Sa12, the CPU 101 generates a change image by arranging the appearance images represented by the appearance data temporarily stored in the RAM 103 by the number of payouts of each denomination.

  In step Sa <b> 13, the CPU 101 generates a receipt image including an image representing information relating to a commercial transaction such as a product name and unit price of the purchased product, a total amount, a deposit amount, and a change amount, and the change image.

  As described above, the CPU 101 has a function as a generation unit.

  FIG. 3 is a diagram showing an example of a receipt image.

  The receipt image shown in FIG. 3 includes a change image IM1. This receipt image is a case where the change amount is 152 yen, and the change image is one appearance image IM11 of 100 yen coin, one appearance image IM12 of 50 yen coin, and appearance image of 1 yen coin. It is an image in which two IM13s are arranged.

  In step Sa14, the CPU 101 instructs the print unit 300 to print the generated receipt image. Specifically, the CPU 101 transmits a print instruction command including image data representing the receipt image generated in step Sa13 from the communication interface 111 to the print unit 300. This print instruction command is given from the communication interface 305 to the CPU 301. Then, the CPU 301 operates the feed motor 306 and the print head 309 to print a receipt image on a print sheet. When the receipt image has been printed on the print paper, the CPU 301 operates the cutter motor 307 to cut the print paper and discharge the receipt. Thus, the CPU 101 has a function as printer control means.

  Thus, the customer who has received the change and the receipt compares the coin received as the change with the change image IM1 displayed on the receipt, and determines the amount of money passed as change and the change displayed on the receipt. Easy to compare.
