Description

Technical Field

[0001] Embodiments of the present invention relate to a product sales data processing apparatus and a program.

Background Art

[0002] In stores such as supermarkets, convenience stores, and restaurants, store clerks use product sales data processing devices such as POS (Point of Sales) terminals and ECRs (Electronic Cash Registers) installed in the store to perform product registration processing and settlement processing on the products sold in the store. Such a product sales data processing device includes a display unit for clerks that displays information to the clerks and a display unit for customers that displays information to the customers.

[0003] The display unit for clerks often uses a large display to display various information related to sales. However, since the display unit for customers displays a small number of characters, for example, a small display that displays a few lines of information may be used.

[0004] Such a small display unit for customers has a limit on the number of characters that can be displayed in the horizontal direction. Therefore, when displaying information that exceeds the number of characters that can be displayed on the display at one time, the information is displayed while being scrolled. When the display of the display unit for customers is scrolled, the display moves, the function of the display cannot catch up with the moving display, and a trailing display with an afterimage remains, resulting in a difficult-to-read display. When a small display is used for the display unit for clerks, the same problem occurs in the display unit for clerks.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The problem to be solved by the present invention is to provide a product sales data processing apparatus and a program capable of easily displaying information that exceeds the number of characters that can be displayed at one time on the display unit.

Means for Solving the Problems

[0006] The product sales data processing device of the embodiment includes a display unit for displaying information, a first determination means for determining whether the information to be displayed on one line exceeds the number of characters that can be displayed on one line of the display unit, and a display control means that, when the first determination means determines that the number of characters that can be displayed on one line of the display unit exceeds the number of characters that can be displayed on one line of the display unit, simultaneously displays first information that can be displayed on one line of the display unit and a mark indicating that there is second information to be displayed on the same line, and displays the second information in place of the first information and the mark after displaying the first information for a predetermined time.

[Modes for carrying out the invention]

[0008] An embodiment will be described below with reference to the drawings. In this embodiment, a POS terminal will be used as an example of a product sales data processing device. A customer display unit will also be described as an example of a display unit. However, the present invention is not limited by the description of the embodiment.

[0009] The POS terminal 10 performs a product registration process for the products purchased by the customer, based on the product code, which is product identification information that identifies the acquired product. The product registration process refers to the process of displaying product information such as the product name and price based on the product code acquired from the read code symbol, and storing the product information in RAM or similar.

[0010] Furthermore, the POS terminal 10 performs payment processing for the products that have been registered. Payment processing refers to the process of displaying the total amount and change related to the transaction with the customer based on the product information of the registered products, and then performing the payment.

[0011] Figure 1 is a perspective view showing the external appearance of the POS terminal 10 according to the embodiment. The POS terminal 10 comprises a main unit 16 and a money storage unit 19. The main unit 16 has a built-in power supply unit and circuit board, and includes an operation unit 11, a printing unit 12, a display unit for store staff 13, a display unit for customers 14, a key switch unit 15, etc. The main unit 16 is also connected to a reading unit 17. The money storage unit 19 has a rectangular casing with a retractable drawer, and stores money (coins and banknotes) given by customers and money prepared by the store as change.

[0012] The operation unit 11 is a keyboard equipped with numerous numeric keys, character keys, and function keys, including a closing key 111 (see Figure 3) for declaring the completion of product registration and closing the process.

[0013] The printing unit 12 is equipped with a thermal head and a transport unit, and the thermal head prints product information and payment information on the receipt paper transported by the transport unit. The POS terminal 10 issues the receipt printed by the printing unit 12.

[0014] The staff display unit 13 displays product information (product name, price, etc.), payment information, and messages for the product corresponding to the acquired product code to the operator (e.g., a store employee) operating the POS terminal 10. The customer display unit 14 displays product information and the total amount of products registered so far to the customer.

[0015] The key switch unit 15 is a switch unit for inserting a key to turn the POS terminal 10 on and off. When a key is inserted into the key switch unit 15 and the inserted key is rotated to the ON position, the POS terminal 10 starts up. When the inserted key is rotated to the OFF position, the power to the POS terminal 10 is turned off and the POS terminal 10 stops.

[0016] The reading unit 17 comprises a light-emitting unit, which is composed of an LED (Light Emitting Diode) or the like, that emits light, and a light-receiving unit, which is composed of a CCD (Charge Coupled Device) or the like, that receives light. The reading unit 17 reads the barcode or other symbol attached to the product by receiving the reflected light from the light-emitting unit, which is reflected by the barcode attached to the product, and the light-receiving unit. The reading unit 17 may also be configured to capture and read the symbol.

[0017] Figure 2 shows the customer display unit 14 of the POS terminal 10. In Figure 2, the customer display unit 14, as an example, has two display areas, one above the other (the upper area is display area A, and the lower area is display area B). Display area A can display a predetermined number of characters or symbols at once. Here, characters include hiragana, katakana, kanji, alphabet, numbers, symbols, etc. When displaying characters from other countries, the characters include the language of that country. The predetermined number of characters (number of characters that can be displayed) is, for example, 16 characters. That is, display area A can display up to 16 characters or symbols at once. Note that one symbol is equivalent to one character. A space is also equivalent to one character. Similarly, display area B can also display up to 16 characters or symbols.

[0018] For example, when displaying "Welcome to ABC Store" and "Today is a special sale day!!" as messages to customers on the customer display unit 14, "Welcome to ABC Store" is displayed in display area A, and "Today is a special sale day!!" is displayed in display area B. In this case, "Welcome to ABC Store" is 21 characters, exceeding the predetermined number of characters. Therefore, in the embodiment, "Welcome to ABC Store" is split into two parts and displayed in display area A. And when displaying for the first time, a mark indicating that there are still characters to be displayed is displayed in display area A together with the first display. The detailed display method will be described later. Also, since "Today is a special sale day!!" is within the predetermined number of characters, it is displayed in display area B as it is (without splitting).

[0019] FIG. 3 is a block diagram showing the hardware configuration of the POS terminal 10. As shown in FIG. 3, the POS terminal 10 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, a memory unit 24, etc. The CPU 21 is an example of a processor and serves as the control entity. The ROM 22 stores various programs. The RAM 23 expands various data. The memory unit 24 stores various programs. The CPU 21, the ROM 22, the RAM 23, and the memory unit 24 are connected to each other via a data bus 25. The CPU 21, the ROM 22, the RAM 23, and the memory unit 24 constitute a control unit 百. That is, the control unit 100 executes the control processing of the POS terminal 10 described later by operating according to the control program stored in the ROM 22 or the memory unit 24 and expanded in the RAM 23 by the CPU 21.

[0020] The RAM 23 stores product information etc. read from and expanded from the product master stored in the memory unit 24 based on the information to be displayed on the store clerk display unit 13 and the customer display unit 14, and the product code read by the reading unit 17.

[0021] The memory unit 24 is a HDD (Hard Disk) or a non-volatile memory that retains stored information even when the power is turned off, and has a program unit 241, a flag unit 242, and a switching time unit 243. The flag unit 242 stores flag information indicating whether to display information in a divided manner or to display it by scrolling. The flag information stored in the flag unit 242 can be changed. The switching time unit 243 stores a predetermined time indicating the time from the display of the first information of the information to be displayed in a divided manner to the display of the second information. The predetermined time stored in the switching time unit 243 can be set and changed.

[0022] Also, the controller 26 is connected to the operation unit 11, the printing unit 12, the display unit 13 for store clerks, the display unit 14 for customers, and the reading unit 17, and executes control over each unit based on commands from the control unit 100. The operation unit 11 has a closing key 111. The closing key 111 is operated when performing settlement processing for the merchandise for which merchandise registration processing has been performed.

[0023] Next, the functional configuration of the POS terminal 10 of the embodiment will be described. FIG. 4 is a functional block diagram showing the functional configuration of the POS terminal 10. The control unit 100 of the POS terminal 10 functions as a first determination means 101, a display control means 102, and a second determination means 103 by operating in accordance with the control programs stored in the ROM 22 and the program unit 241 of the memory unit 24 by the CPU 21.

[0024] The first determination means 101 has the function of determining whether the information to be displayed on one line exceeds the number of characters that can be displayed on one line of the customer display unit 14. Specifically, the first determination means 101 determines whether the number of characters of the information to be displayed on one line exceeds a predetermined number of characters stored in the memory unit 24. Note that the number of characters that can be displayed on one line of the customer display unit 14 varies depending on the size of the characters to be displayed and the spacing between the characters to be displayed, so the memory unit 24 may store predetermined numbers of characters for each character size and character spacing. For example, a matrix-like table with character size on the X axis and character spacing on the Y axis may be created in the memory unit 24, and predetermined numbers of characters based on character size and character spacing may be stored at the intersections of the matrix. The first determination means 101 identifies a predetermined number of characters based on the character size and character spacing, and determines whether it exceeds the number of characters that can be displayed based on the identified predetermined number of characters.

[0025] The display control means 102 has the function of, when the first determination means 101 determines that the number of characters that can be displayed on one line of the customer display unit 14 has been exceeded, simultaneously displaying first information 1421 (see Figure 7) consisting of the number of characters that can be displayed on one line of the customer display unit 14 (a predetermined number of characters) from the information that should be displayed on one line, and a mark 144 (see Figure 7) indicating that there is second information that could not be displayed in the first information 1421. After displaying the first information 1421 for a predetermined time, it displays the remaining second information 1422 that could not be displayed as first information from the information that should be displayed on one line. Specifically, the display control means 102 has the function of simultaneously displaying the first information 1421 and a mark 144 indicating that there is further information 1422 to be displayed on the same line in the display area A of the customer display unit 14 when it determines that the predetermined number of characters has been exceeded, and then displaying the second information 1422 in place of the first information 1421 and the mark 144 after the first information has been displayed for a predetermined time. In this embodiment, the number of characters in the first information is one less than the number of characters that the customer display unit 14 can display (predetermined number of characters), and the number of characters that the customer display unit 14 can display (predetermined number of characters) is reached by adding the mark 144.

[0026] The second determination means 103 has a function to determine whether the display control means 102 should divide the information to be displayed on one line into first information and second information and display it, or scroll it in the line direction, when the first determination means 101 determines that the number of characters of the information to be displayed on one line exceeds the number of characters that can be displayed on one line of the customer display unit 14. Specifically, the second determination means 103 has a function to determine whether the display control means 102 should divide the information to be displayed on one line into first information and second information and display it, or scroll it in the line direction, when the first determination means 101 determines that the number of characters of the information to be displayed on one line exceeds the number of characters that can be displayed (a predetermined number of characters), based on a flag stored in the flag unit 242. If the flag stored in the flag unit 242 is, for example, "0", the second determination means 103 determines to divide the information to be displayed on one line into first information and second information and display it, and if the flag stored in the flag unit 242 is, for example, "1", it determines to scroll the information to be displayed on one line in the line direction.

[0027] Next, the control of the POS terminal 10 will be explained. Figure 5 is a flowchart showing the flow of the control process for the POS terminal 10. As shown in Figure 5, the control unit 100 of the POS terminal 10 displays a message to the customer on the customer display unit 14 before starting a transaction with the customer (S11). There are two types of messages to the customer, for example, "Welcome to ABC Store" and "Today is a special sale day!!". The control unit 100 displays the message "Welcome to ABC Store" in display area A. The control unit 100 also displays the message "Today is a special sale day!!" in display area A. When displaying a message in S11, the control unit 100 performs control based on the flowchart in Figure 6 regarding how to display it on the customer display unit 14.

[0028] In Figure 6, the control unit 100 generates a message to be displayed on the customer display unit 14, line by line (S21). If a message to be displayed on the customer display unit 14 is already stored, the control unit 100 reads that message in S21. Based on the generated (or read) message, the control unit 100 determines the content and number of characters to be displayed on each line of the customer display unit 14. The control unit 100 also determines the size and spacing of the generated characters.

[0029] Next, the first determination means 101 determines for each line of the customer display unit 14 whether the generated message exceeds a predetermined number of characters (S22). The first determination means 101 compares the number of characters it has grasped with the predetermined number of characters that can be displayed on one line stored in the memory unit 24 for each line, and determines for each line whether the number of characters in the generated message exceeds the predetermined number of characters. In this embodiment, the first determination means 101 determines whether the number of characters in the message 142 (information to be displayed on one line) displayed in display area A and the message 143 (information to be displayed on one line) displayed in display area B each exceed the predetermined number of characters.

[0030] If the first determination means 101 determines that the message does not exceed a predetermined number of characters in any line (No. in S22), the display control means 102 displays the generated message on each line of the customer display unit 14 (S23).

[0031] Furthermore, if it is determined that there are lines in the generated message whose number of characters exceeds a predetermined number (Yes in S22), the second determination means 103 then determines whether the flag stored in the flag unit 242 is "0" or "1" (S24). If it is determined that the flag stored in the flag unit 242 is "1" (Yes in S24), the display control means 102 displays the message to be displayed on the line for the line that was determined to exceed the predetermined number of characters, scrolling it in the line direction (S25). For lines that are determined not to exceed the predetermined number of characters, the corresponding message is displayed on that line (S25).

[0032] In this embodiment, the message 142 "Welcome to ABC Store" displayed in display area A exceeds the predetermined number of characters that can be displayed in display area A, so the message is displayed while scrolling in the row direction (left and right direction in Figure 2) (scrolling from right to left) (S25). The scrolling method may be to first display the message "Welcome to ABC Store" that can be displayed in display area A at once, and then scroll the display from right to left to display the rest of "Welcome", or to display the entire message "Welcome to ABC Store" by scrolling from right to left.

[0033] Furthermore, if the flag stored in the flag unit 242 is determined to be "0" (No. in S24), the display control means 102 displays the first information 1421 that can be displayed on that line (S31). In this embodiment, the first information 1421, "Welcome to ABC Store," is displayed in display area A. In addition, the message 143, "Today is a special sale day!!," is displayed in display area B.

[0034] The display control means 102 also displays a mark 144 indicating that there is second information 1422 to be displayed in addition to the first information 1421. The mark 144 is displayed on the same line as the first information 1421 and is also displayed at the end of the first information 1421. Note that since the mark 144 indicates that there is second information other than the first information 1421, it does not necessarily have to be displayed on the same line as the first information 1421. Nor does it necessarily have to be displayed at the end of the first information 1421. Furthermore, for lines that do not exceed the number of characters that can be displayed, the message is displayed on that line. In this embodiment, the mark 144 indicating that there is second information 1422 is displayed at the end of the message "Welcome to ABC Store", which is the first information 1421 displayed in display area A.

[0035] Figure 7 shows the message displayed on the customer display unit 14 by the display control means 102 in S31. As shown in Figure 7, the first piece of information 1421, "Welcome to ABC Store," which is the first to be displayed in the message 142 "Welcome to ABC Store," is displayed in display area A. A finger-shaped mark 144 is displayed at the end of the first piece of information 1421 in display area A to indicate that there is further second information. Note that the mark 144 can be any mark indicating that there is further second information 1422, and is not limited to a finger shape. For example, it could be a star or an asterisk mark. In addition, the message 143 "Today is a special sale day!!" is displayed in display area B. Note that since the message 143 displayed in display area B does not exceed a predetermined number of characters, the mark indicating that there is further second information 1422 is not displayed at the end of the message 143.

[0036] Returning to the explanation of Figure 6, the control unit 100 then activates a timer (not shown) to determine if a predetermined time stored in the switching time unit 243 has elapsed (S32). The control unit 100 waits until the predetermined time has elapsed (No. in S32). While waiting, the display control means 102 continues to display the first information 1421 and the mark 144.

[0037] If the system determines that a predetermined time has elapsed (i.e., that the first information has been displayed for a predetermined time) (Yes in S32), the display control means 102 hides the display of the first information 1421 and mark 144 displayed in display area A, and instead displays the second information (S33). The message 143 displayed in display area B continues to be displayed.

[0038] Figure 8 shows the message displayed on the customer display unit 14 by the display control means 102 in S33. As shown in Figure 8, the second information 1422 of the "Welcome to ABC Store" message 142 is displayed in display area A. Also, the finger-shaped mark 144 indicating that there is further second information 1422 is not displayed at the end of the second information 1422 in display area A. The message 143 "Today is a special sale day!!" is then displayed in display area B.

[0039] Returning to the explanation of Figure 5, the control unit 100 then determines whether it has obtained a product code based on the symbol read by the reading unit 17 (S12). If it determines that a product code has been obtained (Yes in S12), the control unit 100 executes product registration processing for the product based on the obtained product code (S13). The control unit 100 then displays the product information of the registered product on the staff display unit 13 and the customer display unit 14 (S14). When displaying product information on the customer display unit 14 in S14, for example, product information (product name, product price, etc.) is displayed in display area A, and the total amount of products registered so far is displayed in display area B. The control unit 100 performs the same processing as in S11 (i.e., the processing in Figure 6) for the information to be displayed in display area A and display area B, and if the number of characters of the information to be displayed exceeds the number of characters that can be displayed on the customer display unit 14, the display for that line is divided into the display of the first information and mark and the display of the second information thereafter. The control unit 100 then returns to S12. The control unit 100 performs the processes S12 to S14 each time it acquires a new product code.

[0040] Furthermore, if it is determined that the acquisition of a product code is not being performed (No in S12), the control unit 100 determines whether the closing key 111 has been operated (S15). If it is determined that the closing key 111 has been operated (Yes in S15), the control unit 100 executes the settlement process for the product registered in that transaction (S16). The control unit 100 then displays the settlement information processed on the staff display unit 13 and the customer display unit 14 (S17). When displaying the settlement information on the customer display unit 14 in S17, for example, the amount the customer pays is displayed in display area A, and the amount received and change information is displayed in display area B. With respect to the information to be displayed in display area A and display area B, the control unit 100 performs the same processing as in S11 (i.e., the processing in Figure 6), and if the number of characters of the information to be displayed exceeds the number of characters that can be displayed on the customer display unit 14, the display for that line is divided into the display of the first information and mark and the display of the second information thereafter. The control unit 100 then terminates the process.

[0041] Furthermore, if it is determined that the operation is not that of the tightening key 111 (No. in S15), the control unit 100 returns to S11.

[0042] As described above, the POS terminal 10 of the embodiment includes a customer display unit 14 for displaying information, a first determination means 101 for determining whether the information to be displayed on one line exceeds the number of characters that can be displayed on one line of the customer display unit 14, and a display control means 102 that, when the first determination means 101 determines that the number of characters that can be displayed on one line of the customer display unit 14 exceeds the number of characters that can be displayed on one line of the customer display unit 14, simultaneously displays first information 1421 that can be displayed on one line of the customer display unit 14 and a mark 144 indicating that there is further second information 1422 to be displayed on the same line, and after displaying the first information 1421 for a predetermined time, displays the second information 1422 in place of the first information 1421 and the mark 144.

[0043] In this embodiment of the POS terminal 10, if the number of characters in the information to be displayed on the customer display unit 14 exceeds the number of characters that can be displayed on the customer display unit 14, first the first information 1421 is displayed on that line, and a mark 144 indicating that there is second information 1422 related to that information is displayed at the end of the first information 1421 on the same line. After a predetermined time has elapsed, the second information 1422 is displayed on the same line in place of the first information 1421 and the mark 144. As a result, it is possible to display information that exceeds the number of characters that can be displayed on the customer display unit 14 at once in an easy-to-read manner.

[0044] Furthermore, according to the POS terminal 10 of this embodiment, it is possible to set and change a predetermined time in the switching time unit 243. By setting and changing the predetermined time to be optimal for the store, it becomes possible to display information exceeding the number of characters that can be displayed at once on the customer display unit 14 in an easy-to-read manner.

[0045] Furthermore, in the POS terminal 10 of the embodiment, the display control means 102 has a function to scroll the information to be displayed on one line in the row direction when the first determination means 101 determines that the information to be displayed on one line exceeds the number of characters that can be displayed on one line of the customer display unit 14, and the second determination means 10 determines, based on the information of the set flag, whether to display the information to be displayed on one line as first information 1421 and second information 1422 or to scroll it in the row direction when the first determination means 101 determines that the number of characters that can be displayed on one line of the customer display unit 14 exceeds the number of characters that can be displayed on one line, and the second determination means 10 3. Further comprising, the display control means 102, when the second determination means 103 determines that the information to be displayed on one line should be displayed as first information 1421 and second information 1422, simultaneously displays the first information 1421 that can be displayed on one line of the customer display unit 14 and a mark 144 indicating that there is further second information 1422 to be displayed on the same line, displays the first information 1421 for a predetermined time and then displays the second information 1422 in place of the first information 1421 and the mark 144, and when the second determination means 103 determines that the information to be displayed on one line should be displayed by scrolling in the line direction, scrolls the information to be displayed on one line in the line direction.

[0046] According to this embodiment of the POS terminal 10, if the number of characters in the information to be displayed exceeds the number of characters that can be displayed on one line of the customer display unit 14, it is possible to specify, by changing the setting of a flag, whether to display the first information 1421 and the mark 144, and then display the second information 1422, or to scroll through the information to be displayed.

These novel embodiments can be implemented 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.

[0048] For example, in this embodiment, the customer display unit 14 was described as an example of a display unit. However, the invention is not limited to this, and the employee display unit 13 may also be used as a display unit. Alternatively, the employee display unit 13 and the customer display unit 14 may be used as display units.

[0049] Furthermore, in this embodiment, if the number of characters in the information to be displayed exceeds the number of characters that can be displayed on one line of the customer display unit 14, it is possible to specify whether to display the first information 1421 and mark 144, followed by the second information 1422, or to scroll through the information to be displayed. However, this specification function is not mandatory.
