FIG. 1 is an image diagram showing a flow of accounting procedures in a POS (Point Of Sales) system according to an embodiment. First, the printing POS register (product registration device) 20 scans a bar code attached to a product purchased by a customer by a store clerk operation and registers the product.

  When the product registration is completed for all the barcodes of the products purchased by the customer, the printing POS register 20 prints the two-dimensional code (accounting data) on the payment receipt 40, which is a print medium (receipt paper). Issue receipt 40 to the customer. Here, the two-dimensional code is a code indicating purchase contents (purchase information) of all products purchased by the customer and order information indicating the order of purchase contents read when the purchase amount (purchase amount) is settled. It is.

  The customer who has received the payment receipt 40 uses the scanner unit included in the accounting POS register (accounting apparatus) 30 to read the two-dimensional code printed on the payment receipt 40, and the customer himself / herself is the accounting POS. The purchase amount is settled by operating the operation button of the register 30.

  As a result, the store clerk performs product registration and two-dimensional code printing operation, but does not settle the purchase price, and therefore can efficiently perform the accounting process in a short time. In addition, since the store clerk registers the products purchased by the customer, the store clerk can also play a role as a security supervisor in order to prevent tampering with the product registration.

  Note that the POS register 20 for issuing the payment receipt 40 on which the two-dimensional code is printed, and the accounting POS register for adjusting the purchase price of the product based on the two-dimensional code printed on the payment receipt 40. It is not necessary to have the same number of 30 installations. For example, the processing time in the accounting POS register 30 is short because accounting is performed based on a two-dimensional code, so the number of accounting POS registers 30 may be reduced.

  Thus, if the number of accounting POS registers 30 is reduced and the area where the accounting POS registers 30 are installed is reduced, the reduced area can be effectively used as the sales floor area. In addition, if at least one of the printing POS register 20 and the accounting POS register 30 is reduced, the time required for accounting processing can be greatly reduced as compared with the conventional POS system.

  Returning to FIG. 4, the description of the configuration of the accounting POS register will be continued. The operation unit 306 includes various operation buttons (such as a correction key and a preset key) for operating the accounting POS register 30. For example, the operation unit 206 accepts correction of an operation input by operating an operation button (correction key).

  The communication unit 307 communicates with other devices via the LAN 11. For example, the latest product master is acquired from the store controller 10 by connecting to the store controller 10. For example, if the latest product master is stored in the RAM 303 via a storage medium such as a CD-ROM, the communication unit 307 is not necessarily connected to the store controller 10.

When an error or the like occurs, the buzzer 308 generates a buzzer sound that notifies the error.
The printing unit 309 prints and issues an accounting receipt that the customer takes home when accounting (settlement of the purchase price of the product) is completed.

Next, the operation procedure of the accounting POS register 30 will be described.
FIG. 9 is a flowchart illustrating the operation of the accounting POS register in one embodiment. The CPU 301 detects a device connected to the port of the accounting POS register 30 (port of the settlement devices 310 to 312) (step S200). Then, the CPU 301 stores identification information for identifying the device in the work area of the RAM 303 (step S210).

  The CPU 301 determines whether or not detection has been completed for all ports (step S220). When a port that has not been detected remains (step S220—NO), the CPU 301 proceeds to step S200. On the other hand, when the detection is completed for all ports (step S220—YES), the CPU 301 reads identification information for identifying the device from the work area of the RAM 303 (step S230).

  The CPU 301 selects identification information for identifying the settlement apparatus from the identification information read from the RAM 303. Then, the CPU 301 searches and specifies terminal information stored in the RAM 303 for a payment apparatus that can be executed by the payment apparatus identified by the selected identification information. Moreover, CPU301 reads the classification of the payment which a payment apparatus can perform from the specified terminal information. (Step S240).

  The CPU 301 determines from the identification information read from the work area of the RAM 303 whether or not the identification of all of the payment devices 310 to 312 has been completed (step S250). When the identification information of the unspecified settlement device remains (step S250—NO), the CPU 301 proceeds to step S230. On the other hand, when all selection of the identification information of the settlement apparatuses 310 to 312 has been completed (step S250—YES), the CPU 301 determines the display size of the operation button (step S260). Then, the CPU 301 displays a screen including operation buttons on the screen of the display unit 305 (step S270).

  As described above, the identification information for identifying the payment devices 310 to 312 is connected from the connection ports 310 to 312 to the payment device that executes the payment for the product purchased by the customer in accordance with the operation input by the operation button displayed on the screen. The CPU 301 that acquires and identifies the payment device based on the identification information, the CPU 301 that determines the display size of the operation button corresponding to the payment device based on the payment device specified by the CPU 301, and the display size that the CPU 301 determines. Thus, the accounting POS register 30 includes a display unit 305 that displays operation buttons in an area on the screen.

  As a result, the accounting POS register displays the operation buttons in accordance with the connected payment apparatus, so that the operation buttons of the payment apparatus capable of executing payment can be displayed on the screen so that the customer can easily operate.

  Further, the CPU 301 determines the display size of the operation buttons based on the size of the display area of the screen and the number of connected payment devices. As a result, the accounting POS register displays only the operation buttons of the connected settlement apparatus in the area in the screen and the operation buttons with the maximum size that can be displayed in the display area. Or a store clerk) is easy to operate.

  Further, the CPU 301 determines a position where the operation button is displayed in the display area of the screen based on the history of operation of the operation button. Thereby, the accounting POS register can determine the display position based on the history of operating the operation buttons.

  Also, since the right-handed population is larger worldwide than the left-handed population, the reflexively moving hand among the left and right hands of the operator (customer, store clerk, etc.) is often the right hand. For this reason, the CPU 301 may determine the arrangement order of the operation buttons in the display area of the screen so that the operation buttons are displayed from the right side of the screen in the descending order of the operated history. As a result, the flow line of the right hand is shortened when operating, so that the operator can perform button operations smoothly. In addition, since the operator can easily perform an intuitive operation, the usability of the accounting POS register is improved.

  Further, the use of the operation history may not be limited to determining the display position and arrangement order of the operation buttons. For example, the accounting POS register may display the display size of the operation button having a large operation history larger than that of the operation button having a small operation history. Thereby, since the operator can perform the button operation more smoothly, the operator can easily perform an intuitive operation, and the usability of the accounting POS register can be further improved. In addition, the operator can reduce erroneous operations.

  Further, the POS system has a receipt printing unit 209 that prints on the receipt 40 for payment a code for payment that is read when the purchase price of the product is settled based on the code information attached to the product purchased by the customer. Identification information for identifying the settlement apparatuses 310 to 312 is determined from the settlement apparatuses 310 to 312 that perform settlement for the product in accordance with the print POS register 20, the settlement code, and the operation input by the operation button displayed on the screen. CPU 301 for acquiring and identifying a payment device based on the identification information, and a display unit 305 for displaying an operation button corresponding to the payment device in an area in the screen based on the payment device specified by CPU 301. And an accounting POS register 30.

  As a result, the POS system can display an operation button for executing payment on the screen so that the customer can easily operate, depending on a payment apparatus that is connected and capable of executing payment.

  Further, the POS register detects the payment devices connected to the ports for all ports when the power is turned on or when an instruction is given to specify the payment device.

  As a result, the POS register and the POS system can identify the settlement apparatus without using the setting operation performed by the maintenance personnel who maintain the POS register, and display the operation buttons according to the settlement apparatus that can perform the identified settlement. it can.

  Note that the payment POS register 30 may be connected to payment devices corresponding to more payment devices. FIG. 10 shows a display example of a selection screen that is displayed on the display unit of the accounting POS register and allows the customer to select a settlement apparatus in one embodiment. This selection screen is a screen corresponding to FIG. 7, and compared with the case shown in FIG. 7, the settlement devices corresponding to many settlement devices “electronic money B settlement” to “electronic money E settlement” It is a payment apparatus selection screen displayed when further connected to the POS register 30. As an example, in FIG. 10, operation buttons “cash”, “credit”, and “electronic money A” to “electronic money E” are displayed in the lower half area of the selection screen.

  When the division result obtained by dividing the size in the width direction of the area where the operation button is displayed in the screen by the number of connected payment devices is shorter than a predetermined size (threshold), the CPU 301 determines in advance. The operation buttons are displayed over a plurality of lines with the specified size in the width direction. The display size in the height direction is determined according to the number of rows of operation buttons. For example, the CPU 301 sets a division result obtained by dividing the size in the height direction of the area in the screen where the operation buttons are displayed by the number of rows of the operation buttons as the display size in the height direction of the operation buttons.

  Also, since the right-handed population is larger worldwide than the left-handed population, the reflexively moving hand among the left and right hands of the operator (customer, store clerk, etc.) is often the right hand. For this reason, the CPU 301 may determine the arrangement order of the operation buttons in the display area of the screen so that the operation buttons are displayed from the right side of the screen in the descending order of the operated history. As a result, the flow line of the right hand is shortened when operating, so that the operator can perform button operations smoothly. In addition, since the operator can easily perform an intuitive operation, the usability of the accounting POS register is improved.

  Further, the use of the operation history may not be limited to determining the display position and arrangement order of the operation buttons.
