Hereinafter, an embodiment will be described.
In the present embodiment, a POS terminal 1 used in a retail store is illustrated as an example of a payment processing apparatus.

[POS terminal]
FIG. 1 is a block diagram showing a main configuration of the POS terminal 1 in the present embodiment.
The POS terminal 1 includes a CPU (Central Processing Unit) 10 that functions as a control center. The CPU 10 includes a memory 11, a communication I / F (Interface) 12, a scanner I / F 13, a keyboard controller 14, display controllers 15 and 16, a printer controller 17, and the like that are configured by an address bus, a data bus, and the like. They are connected via line 18.

  Further, a communication line 20 such as a LAN (Local Area Network) line in the store is connected to the communication I / F 12, a barcode scanner 21 is connected to the scanner I / F 13, a keyboard 22 is connected to the keyboard controller 14, and a display A store clerk display 23 is connected to the controller 15, a customer display 24 is connected to the display controller 16, and a receipt printer 25 is connected to the printer controller 17.

  The memory 11 is composed of a ROM (Read Only Memory) and a RAM (Random Access Memory), and a computer program executed by the CPU 10 to realize setting processing and settlement processing described later, fixed data such as various fixed values, and the like. A key procedure table 30 and the like are stored. If the POS terminal 1 is accessible, the key procedure table 30 may be stored in a storage medium other than the memory 11, for example, an external storage medium or a memory included in another device connected to the POS terminal 1. Good.

  The communication I / F 12 transmits and receives data to and from various devices such as a server and a printer that are connected for communication via the communication line 20.

  The barcode scanner 21 optically reads a barcode attached to a product or the like and generates code information such as a PLU code. The scanner I / F 13 takes in the code information generated by the barcode scanner 21, converts it into a key event, and outputs it to the CPU 10.

  The keyboard 22 includes a PLU key for inputting an instruction for starting a settlement process, a subtotal key for inputting a subtotal instruction, a numeric keypad for inputting a numerical value, a closing key for inputting a closing instruction for the settlement process, and the like. The key number indicating the pressed key is output. The keyboard controller 14 captures the key number output from the keyboard 22 and outputs it to the CPU 10.

  The clerk-side display 23 includes, for example, an LCD (Liquid Crystal Display) 231 whose display surface is directed to the clerk's standing position side, and a touch panel 232 provided on the display surface of the LCD 231. The display controller 15 controls the clerk-side display 23 in response to a command from the CPU 10 and causes the LCD 231 to display a payment processing screen or the like. Further, the display controller 15 detects a GUI operation displayed on the LCD 231 based on a signal output when the touch panel 232 is touched, and notifies the CPU 10 of the detected operation.

  An example of the settlement processing screen is shown in FIG. The screen 40 shown has a settlement information display area 41 and five button areas 51 to 55 arranged from the lower left end of the screen toward the lower right end. In the payment information display area 41, various information necessary for the payment processing such as the name and unit price of the registered product and the total price of the unit price of the registered product, a preset key for registering the specific product, and the like are arranged. In the button areas 51 to 55, names of input keys that are operation candidates are displayed through candidate display processing described later. The preset keys and button areas 51 to 55 are GUIs that can be operated by touching the touch panel 232.

  The customer side display 24 is, for example, an LED display whose display surface is directed to the standing position side of a customer who receives a transaction. The display controller 16 controls the customer-side display 24 to display the price of individual commodities purchased by the customer in one transaction, the total price obtained by adding them up, and the change amount.

  The receipt printer 25 is a thermal printer that prints various types of information on receipt paper, which is thermal paper, for example. The printer controller 17 controls the operation of the receipt printer 25 to issue a receipt printed with the name, unit price, total price, change amount, etc. of the product purchased by the customer.

[Key procedure table]
The data structure of the key procedure table 30 will be described.
FIG. 3 is a diagram illustrating a data structure example of the key procedure table 30 in the present embodiment.
The key procedure table 30 includes data including stage information, key numbers, key names, and usage frequencies.

  The key number is a number uniquely set for key input by operating each key of the keyboard 22 or an input key such as a preset key displayed on the LCD 231. It should be noted that the input of code information read by the barcode scanner 21 is also converted into a key event and treated as a key input. Therefore, the key procedure table 30 also includes data having a key number set for the input of code information from the barcode scanner 21.

  The stage information indicates the processing status where the operation of each input key is valid. The processing status here includes, for example, a state in which the initialization process immediately after the activation of the POS terminal 1 is being executed, a state in which payment processing is started and product registration is accepted, and payment for the registered product is accepted. The stage information such as “1”, “2”... Is assigned in advance to such a processing situation.

  The key name indicates a function assigned to the key input indicated by the corresponding key number. For example, if the function corresponds to key input by operating a subtotal key provided on the keyboard 22, for example, “input subtotal instruction”, the preset key for registering the product A displayed on the LCD 231 is operated. If the function corresponds to the key input, the process to be executed when the corresponding key input is made, such as “Register product A” is shown.

  The usage frequency indicates the number of times the key input indicated by the corresponding key number is executed, and is represented by a two-digit number in this embodiment. Therefore, “99” is the maximum use frequency.

[Initialization]
Next, the operation of the POS terminal 1 will be described.
Immediately after the power is supplied to the POS terminal 1 and the operating system is started, the initialization process shown in the flowchart of FIG. 4 is first executed.

In the initialization process, the CPU 10 creates the candidate data table 31 in the memory 11 (step S101) and executes the candidate display process using the stage information immediately after startup (step S102).
FIG. 5 shows an example of the data structure of the candidate data table 31. As shown in FIG.
The candidate data table 31 is configured by assigning numbers in ascending order to areas for describing key numbers and key names. When the candidate data table 31 is created in the process of step S101, each area is blank.

[Candidate display processing]
Next, the candidate display process will be described.
In the candidate display process, the CPU 10 operates according to the flowchart of FIG. That is, first, the CPU 10 searches the key procedure table 30 for data including stage information indicating the current processing status (step S201). The input key indicated by the key number of the data found at this time is an input key whose operation is effective in the current processing situation.

  In the process of step S201, for example, a table in which the key information is associated with the stage information indicating the processing status to be transferred when the key input indicated by the key number is made is stored in the memory 11. The key number of the previous key input is searched from this table, and the stage information associated with the found key number is used for searching the data as indicating the current processing status. The stage information used in each process described below may be specified by the same method.

  Next, if data is described in the candidate data table 31, the CPU 10 once deletes the data, and then assigns the key number and key name included in each data found in the process of step S201 to the candidate data table. 31 is written (step S202). At this time, the key numbers and key names included in the data found in the process of step S201 are written from the number “1” area of the candidate data table 31 in order from the most frequently used data included in the data. .

  However, if each data found in the process of step S201 includes data corresponding to a key input by the barcode scanner 21, the data is excluded from being written to the candidate data table 31.

After the process of step S202, the CPU 10 displays the key names of the areas having the numbers “1” to “K” among the key names written in the candidate data table 31 in the button areas 51 to 55 of the screen 40. (Step S203). Here, K is an integer of 1 or more, and its value is determined in advance and stored in the memory 11 or the like. Hereinafter, in this embodiment, the description will be continued assuming that K = 5.
The candidate display process ends with the process of step S203.
After such a candidate display process for the flow, the screen parts (button areas 51 to 55) on which the stage information described in the key procedure table 30 represents the input key indicating the current processing status are displayed in the key procedure table 30. Are displayed on the store clerk side display 23 in the order of the frequency of use of each of these input keys.

Here, a specific example of candidate display processing will be given.
In the candidate display process in the initialization process, if the stage information is “1”, the key numbers “10” “21” “34” “6” “9” “14” from the key procedure table 30 shown in FIG. Is found (step S201). Furthermore, as shown in FIG. 7, the key numbers and key names included in these data are in the order of use, that is, the key numbers and key names are “21, function F21” “9, function F09” “34, function F34”. The data are written in the candidate data table 31 in the order of “6, function F06”, “14, function F14”, “10, function F10” (step S202).

  Of the data thus written, the key names of the areas to which the numbers “1” to “K” (= 5) are attached, that is, “function F21” “function F09” “function F34” “function F06”. “Function F14” is displayed in the button areas 51 to 55 of the screen 40 as shown in FIG. 8 (step S203).

[Payment processing]
When the initialization process is completed, the settlement process is executed.
In payment processing, registration of products to be purchased by customers, acceptance of discounts, calculation of the total price of registered products, acceptance of payment of payments, calculation of service points granted to customers, issuance of receipts, etc. Is done.

These are basically realized by the CPU 10 operating according to the flowchart of FIG.
In this flowchart, first, the CPU 10 receives a key input by operating the keyboard 22, the clerk-side display 23, and the barcode scanner 21 (step S301).

  At this time, if any key of the keyboard 22 is operated, the CPU 10 receives a key input by the key.

  Further, when the GUI such as the preset key displayed on the LCD 231 or the button areas 51 to 55 is touched, the operation is detected by the display controller 15 based on the output from the touch panel 232 and notified to the CPU 10. At this time, if the operation is a preset key arranged in the settlement information display area 41, the CPU 10 accepts a key input assigned to the preset key. On the other hand, if the operation is any one of the button areas 51 to 55, the CPU 10 refers to the data of the operated button area in the candidate data table 31, and the key input indicated by the key number included in the data Is considered accepted.

  If the barcode is read by the barcode scanner 21, the scanner I / F 13 takes in the code information output from the barcode scanner 21, converts it into a key event, and notifies the CPU 10 (step S301b). At this time, the CPU 10 considers that a key input “input of code information” has been received.

  When a key input from any of the keyboard 22, the clerk-side display 23, and the barcode scanner 21 is received in the process of step S301, the CPU 10 determines whether the key input is valid in the current processing status. Therefore, the key procedure analysis is performed (step S302). In this process, the CPU 10 searches the key procedure table 30 for data including both stage information indicating the current processing status and the key number corresponding to the key input, and if the corresponding data is found, the key input is performed. Is valid, and if the corresponding data cannot be found, the key input is invalid.

  After executing the key procedure analysis of such a flow, the CPU 10 determines the result (step S303). When it is determined that the key input is valid in the key procedure analysis, the CPU 10 determines that the procedure is valid (No in step S303) and executes the frequency learning process (step S304). This frequency learning process will be described later with reference to FIG.

  After the frequency learning process, the CPU 10 performs a process corresponding to the function assigned to the key input received in the process of step S301 (step S305). For example, if the key number set for the key input accepted in step S301 is “10”, the key name “function F10” included in the data having the key number “10” in the key procedure table 30. The process corresponding to is performed.

After the process of step S305, the CPU 10 executes the above-described candidate display process (step S306).
On the other hand, if it is determined that the key number input is invalid in the key procedure analysis in step S302, the CPU 10 determines that it is a procedure error (Yes in step S303) and displays candidates without performing the processing in steps S304 and S305. Processing is executed (step S306).

As a result of execution of the candidate display process in step S306, the top five key names with the highest use frequency are displayed in the button areas 51 to 55, respectively, among the input keys whose operations are valid in the current processing situation.
After the candidate display process, the CPU 10 returns to the process of step S301 and accepts the next key input.

[Frequency learning process]
Next, the frequency learning process in step S304 will be described.
In the frequency learning process, the CPU 10 operates according to the flowchart of FIG. That is, first, the CPU 10 searches the key procedure table 30 for data including both the stage information indicating the current processing status and the key number set for the key input received in the processing of step S301 (step S401). . Then, the CPU 10 determines whether or not the usage frequency included in the found data has reached the maximum frequency, that is, “99” (step S402).

  When the use frequency included in the found data is not the maximum frequency (No in step S402), the CPU 10 updates the use frequency of the data with a value obtained by incrementing the use frequency in the key procedure table 30 by one (step S403). ), The frequency learning process is terminated.

  On the other hand, when the usage frequency included in the found data is the maximum frequency (Yes in step S402), the CPU 10 searches the key procedure table 30 for data including stage information indicating the current processing status (step S404).

  Then, the CPU 10 updates the use frequency included in each piece of data by dividing the use frequency contained in each piece of found data by 2 (rounded up) (step S405), and ends the frequency learning process. .

  In the process of step S405, the usage frequency included in each discovered data may be divided by a number of 3 or more, or the predetermined number may be reduced.

  As described above, the POS terminal 1 according to the present embodiment uses the plurality of input keys to which a predetermined function is assigned, the stage information indicating the processing status in which the operation of each input key is valid, and the use of each input key. A key procedure table 30 having a frequency described therein, and a screen component representing an input key corresponding to one indicating the current processing status among the stage information described in the key procedure table 30 is stored in the key procedure table 30. These are displayed on the store clerk display 23 in the order of use frequency of each of the described input keys.

  With such a configuration, it is possible to notify the operator of frequently used input keys in each processing situation, so that an operation error is prevented and rapid key input is possible. As a result, smooth progress of the payment process can be expected. Furthermore, the training time for those who are unfamiliar with the operation of the POS terminal 1 can be shortened.

  The POS terminal 1 counts up the frequency of use of the operated input key described in the key procedure table 30 every time one of the input keys is operated. With such a configuration, the usage frequency can always be kept up-to-date.

  Further, if the use frequency stored in the key procedure table 30 of the operated input key reaches a predetermined maximum number, the POS terminal 1 stores the stage information stored in the key procedure table 30 as the current information. The frequency of use of the input key indicating the processing status is reduced by a predetermined ratio (1/2 in this embodiment). With such a configuration, even after the usage frequency stored in the key procedure table 30 reaches the maximum number, the usage frequency ratios of the input keys whose operations are effective in the same processing situation are not changed. The value is reduced.

  Further, when a touch operation on any one of the button areas 51 to 55 is detected by the touch panel 232, the POS terminal 1 executes a process based on a function assigned to the input key represented by the touched button area. In this way, if processing by the same function as when the input key is operated by operating the button areas 51 to 55 where the input key candidates are displayed, it is possible to quickly search without searching for the input key from the keyboard 22 or the like. In addition, desired key input can be easily performed.

  In the button areas 51 to 55, key names of a predetermined number of input keys having a higher usage frequency among the input keys whose stage information described in the key procedure table 30 indicates the current processing status are displayed. With such a configuration, it is possible to notify the operator only of the input keys that are frequently used.
