Description

  The present invention relates to a POS register that displays information on products purchased by a customer.

In recent years, in stores such as supermarkets, there are an increasing number of stores that have introduced “self-POS (Point Of Sales) registers” in which customers themselves complete the accounting by operating cash registers.
In the self-POS register, first, a customer reads a product barcode using a scanner and registers the product. When product registration is performed, the self-POS register displays the purchase details on the display screen. Next, when the customer inserts cash (or a card) into the self-POS register, the self-POS register changes when there is a receipt and a change. The customer performs a series of operations to receive and return the receipt and change issued from the self-POS register.

  The self-POS register has an advantage that once the customer has learned the operation, the accounting can be completed quickly when the number of shopping points is small. In order to take advantage of this advantage, it is conceivable to replace some of the plurality of POS registers operated by the store clerk with self-POS registers. Then, by having a customer with a small number of shopping points use the self-POS register, it is possible to disperse customers waiting for accounting, prevent queues for accounting, and improve customer satisfaction.

  In the technique described in Patent Document 1, when a list composed of a plurality of columns is displayed, if a display magnification is changed, a column to be displayed is displayed based on the setting. Patent Document 2 describes a payment terminal that can specify the font size of information displayed on a display unit.

The purpose of introducing the self-POS register to distribute customers waiting for accounting, prevent queues for accounting, and improve customer satisfaction by having customers with a small number of shopping points use the self-POS register It is. However, the self-POS register in the prior art performs accounting by displaying purchase details on the display unit with a predetermined character size (character size) and a predetermined number of display items regardless of whether the number of purchased items of the customer is large or small. Therefore, for example, even if the number of shopping items is small, the characters are displayed small, so that the operability is lowered due to reasons such as difficulty in viewing, and the efficiency of customer visitation may be lowered.
For this reason, it is conceivable to easily confirm the product name and the number of points purchased by displaying the purchase details of the customer with a small number of points of purchase using the techniques described in Patent Documents 1 and 2. However, each time the operator (customer) has to change the size of characters to be displayed by button operation, there is a drawback that it takes time and effort.
In addition, depending on the button operation of the customer who has finished accounting one time ago, the purchase details may be displayed in large letters as they are, but in the case of a customer with many purchase points, the displayed letters are large and one The purchase details do not fit on the screen, and the purchase details are displayed on a plurality of screens (pages). Therefore, there is a drawback in that it is not possible to confirm all product names and purchase points in the purchase details unless the operator (customer) switches the screen.
Further, in any case, there is a problem that the character size (size of characters) and the number of display items cannot be changed unless the operator (customer) performs button operation or the like.

  The present invention has been made in view of such circumstances, and its purpose is to improve the operability of the self-POS register by making it easier to see the purchase details displayed on the self-POS register. It is to improve efficiency.

The present invention has been made to solve the above problems, one aspect of the present invention, when purchasing items product code of the registered goods are identical, the purchase items in the same commodity code 1 Characters for generating a purchase detail for display including the collected purchase details and determining a character size for displaying the purchase details based on the number of items for each product code of the generated purchase details for display a size determining means, wherein at character size character size determination means has determined, and display means for displaying the purchase items for display the generated display the number of purchase items for the display and the display means displays the If it is the predetermined number or more, changes Misao the purchase item for the display to display for each predetermined number to change the character size to be displayed in the purchase item for each of the predetermined number to a large And means, wherein the display means, the character size by the change operation means for when it is changed to the large, and displaying the purchase items for each of the predetermined number in the changed character size display Device.

According to this invention, the display character size in the purchase details is determined based on the number of items of the registered product. For this reason, if the number of items purchased by the customer is small, the display device can display the purchase details in large letters that are easy to see the purchase details without any unnecessary operations or manual intervention. The visual confirmation of the score becomes easy and the accounting operation can be performed smoothly. Thereby, the operability of the POS register provided with the display device can be improved, and the waiting queue can be eliminated.
Further, according to the present invention, since the character size in the purchase details can be changed by the operator's intention, the purchase details can be displayed in large characters even when the number of items of products purchased by the customer is large. Can do. Thereby, since the name of the product to purchase and its purchase points can be easily visually confirmed, the accounting operation can be performed smoothly. Further, by displaying and confirming many products at a time, the number of screen display switching can be reduced.

According to another aspect of the present invention, in the above display device , when the change operation unit changes the character size for displaying the purchase details to a large size, the purchase details displayed by the display unit are scrolled in units of screens. A scroll button to be displayed is displayed .

According to the present invention, the display device can scroll purchase details in units of screens . Thereby, since the name of the product to purchase and its purchase points can be easily visually confirmed, the accounting operation can be performed smoothly.

Further, according to one aspect of the present invention, in the above display device , a display pattern table that stores a number of purchase details of the customer to be displayed on the display unit or a character size for displaying the purchase details is stored. The display means displays the purchase details of the customer based on the display pattern table, and when the change operation means is operated, the display pattern in the display pattern table is cyclically switched to display the purchase details of the customer. It is characterized by doing.

According to this invention, the display device can display the purchase details of the customer by cyclically switching the display patterns in the display pattern table .

  According to the present invention, the display character size in the purchase details is determined based on the number of items of registered merchandise. For this reason, when the number of items of products purchased by the customer is small, it is possible to display the purchase details in large characters that are easy to view without unnecessary operations or manual intervention. Further, when the number of items purchased by the customer is large, the details displayed on one screen can be increased, so that the number of times of switching the screen can be reduced. This facilitates visual confirmation of the name of the product to be purchased and the number of purchased items, and allows the accounting operation to be performed smoothly. For this reason, the operability of the POS register is improved, and the queue for accounting can be quickly eliminated by improving the efficiency of customer purchase.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic diagram showing the configuration of a POS system according to an embodiment of the present invention. As shown in FIG. 1, the POS system includes a store controller 10, N (N is an integer of 1 or more) printing POS registers 20, and M (M is an integer of 1 or more) accounting POS registers ( Self-POS register) 30. The print POS register 20 includes one connected to the store controller 10 via a LAN (Local Area Network) 110 and one not connected thereto. Similarly, there are accounting POS registers 30 that are connected to the store controller 10 via the LAN 110 and those that are not connected. In FIG. 1, each printing POS register 20 and each accounting POS register 30 are not necessarily connected via the LAN 110. The LAN connection may be any connection such as wired or wireless.

  The store controller 10 is a computer that controls the POS system, and manages various information such as a product master. The store controller 10 transmits the latest product master to each printing POS register 20 and accounting POS register 30 as appropriate. The product master is a file storing product information such as a product code, a product name, and a sales price, which is product identification information of each product, and is appropriately updated.

  The printing POS register 20 is a device for printing all purchase information of products purchased by the customer as codes (settlement codes) on receipts. The purchase information is information on a product purchased by a customer, for example, code information which is information represented by a barcode attached to the product. The code information includes a product code and the like. The printing POS register 20 includes various operation keys and a display unit. The printing POS register 20 is connected to a bar code scanner that reads a bar code (product code) attached to a product purchased by a customer by the operation of a store clerk. The code (settlement code) printed on the print medium (receipt paper) is a two-dimensional code (for example, QR (Quick Response) code (registered trademark)). Accordingly, the printing POS register 20 reads code information (barcode) attached to the product purchased by the customer, and a code (two-dimensional code) representing customer purchase information based on the read barcode. Since this is a device that prints the two-dimensional code on a receipt, there is no problem in printing even if it is not connected to the store controller 10 via the LAN.

  The accounting POS register 30 is a device for performing accounting by reading a code (settlement code: for example, a two-dimensional code) printed on a print medium (receipt). The accounting POS register 30 includes a scanner unit 304 that reads a code. The accounting POS register 30 stores a copy of the product master managed by the store controller 10 in the RAM 303. The accounting POS register 30 can appropriately acquire the latest product master directly from the store controller 10 and store it in the RAM 303. If the latest product master is stored in advance in the RAM 303 of the accounting POS register 30 using a medium (for example, a CD-ROM), accounting is possible even if it is not connected to the store controller 10 via the LAN. Is no problem.

  Next, the electrical configuration of the printing POS register 20 will be described with reference to FIG. The POS register 20 includes a CPU (Central Processing Unit) 201, a ROM 202, a RAM 203, a scanner unit 204, a display unit (for a store clerk) 205, a display unit (for a customer) 205a, an operation unit 206, and a communication unit. 207, a buzzer 208, a receipt printing unit 209, and a hard disk 210, which are connected to each other via a bus and can communicate with each other.

  The CPU 201 is a central processing unit, and controls the operation of the printing POS register 20 by reading and executing a program stored in the ROM 202. The ROM 202 is a read-only memory that stores the program. The RAM 203 is an occasional read / write memory that stores various information. The scanner unit 204 optically reads a barcode (product code) attached to a product. For example, the RAM 203 stores a barcode (product code) read by the scanner unit 204.

  The display unit (for clerk) 205 and the display unit (for customer) 205a display various information. For example, the display unit (for store clerk) 205 and the display unit (for customer) 205a display information acquired from the product master (for example, product name, price, etc.). Further, since the display unit (for clerk) 205 is a touch panel type (for example, a liquid crystal touch panel), in addition to the display to the clerk, the product of the product set and registered in advance on a button (preset button) provided on the screen Accepts input of information (product code, etc.).

  The operation unit 206 includes operation buttons such as various keys for operating the POS register 20, a subtotal key, a current key, a numeric key, a correction key, and a preset key. For example, the operation unit 206 accepts input of product information (product code or the like) that is preset and registered in the preset key.

  The communication unit 207 communicates with the store controller 10 via the LAN 110. Since the printing POS register 20 is a device that prints customer purchase information on a receipt using a two-dimensional code, the communication unit 207 may not be connected to the store controller 10 or the like via a LAN. The buzzer 208 generates a buzzer sound when confirmation of operation is necessary.

  The receipt printing unit 209 prints a two-dimensional code (QR code (registered trademark)) on the receipt. The hard disk 210 stores customer purchase information (including order information) stored in the RAM 203 after printing on the receipt.

  Next, the electrical configuration of the accounting POS register 30 will be described with reference to FIG. As shown in FIG. 3, the accounting POS register 30 includes a CPU 301, a ROM 302, a RAM 303, a scanner unit (reading unit) 304, a display unit (notification unit) 305, an operation unit 306, and a communication unit 307. The buzzer 308 and the printing unit 309 are connected to each other via a bus and can communicate with each other.

  The CPU 301 is a central processing unit, and controls the operation of the accounting POS register 30 by reading and executing a program stored in the ROM 302. The ROM 302 is a read-only memory that stores the program.

  The scanner unit 304 optically receives either a two-dimensional code (QR code (registered trademark)) of a receipt printed by the printing POS register 20 or a bar code (product code) attached to a product. read. The RAM 303 is a read / write memory that stores various information as needed. For example, the RAM 303 stores a product master acquired from the store controller 10, product purchase information indicated by a two-dimensional barcode read by the scanner unit 304, and the like.

  The display unit 305 displays various information. For example, based on the code information read by the scanner unit 304, the purchase details of the product purchased by the customer are displayed. The operation unit 306 includes operation buttons for various keys (for example, a subtotal key, a current total key, a numeric key, a correction key, and a deposit key) that operate the POS register 30.

  The communication unit 307 communicates with the store controller 10 via the LAN 110. For example, the latest product master is acquired from the store controller 10 by connecting to the store controller 10. The buzzer 308 generates a buzzer sound such as an error. The printing unit 309 prints an accounting receipt taken back by the customer after the customer's accounting is completed.

  Next, the display setting table and display pattern table stored in the RAM 303 will be described. FIG. 4 is a schematic diagram illustrating a data structure and a data example of the display setting table in the present embodiment. As shown in the figure, the display setting table is two-dimensional tabular data composed of rows and columns, and has columns for conditions and items of display patterns. Each row of this display setting table exists for each condition. The condition is a condition related to the number of items of products purchased by the customer. The display pattern is an identification number that uniquely determines the number of items and the character size of the product displayed in the purchase details.

  FIG. 5 is a schematic diagram illustrating a data structure and a data example of the display pattern table in the present embodiment. As shown in the figure, the display pattern table is data in a two-dimensional tabular format composed of rows and columns, and includes columns for each item of display pattern, number of items, and character size. Each row of the display setting table exists for each display pattern. The number of items is the number of items of products displayed on the purchase details. The character size is the display character size in the purchase details.

  Next, an outline of the flow of accounting processing in the POS system will be described with reference to FIG. FIG. 6 is an image diagram showing the configuration of the POS system according to the present embodiment. First, in the POS register 20 for printing, the store clerk uses the scanner unit 204 to read the barcode of the product purchased by the customer. When the clerk reads the bar code for all the products purchased by the customer, the sales clerk issues a payment receipt 50 by the printing unit 209 and hands it to the customer. The payment receipt 50 is a receipt on which a two-dimensional code including customer purchase information is printed.

  Next, the customer who has received the payment receipt 50 uses the scanner unit 304 of the payment POS register 30 to read the two-dimensional code printed on the payment receipt 50 and perform payment. As described above, since the store clerk performs product registration and two-dimensional code printing operation, the registration process can be performed in a certain time with high efficiency. In addition, since the store clerk registers the product, it is possible to monitor the product registration by a malicious customer so that the product registration is not falsified. Therefore, the store clerk also plays a role of monitoring in terms of security.

  In addition, it is not necessary to have the same number of installed POS registers 20 for issuing a receipt printed with a two-dimensional code and accounting POS registers 30 for performing accounting based on the two-dimensional code printed on the receipt. The number of accounting POS registers 30 that require a short accounting time may be reduced. Since the POS register installation space can be reduced by reducing the number of accounting POS registers 30, the POS register installation space can be effectively used as a sales floor area. Even if the number of POS registers is reduced, the accounting processing time of the POS registers can be greatly shortened and the accounting waiting time can be shortened as compared with the conventional POS system.

Next, the flow of accounting processing in the accounting POS register 30 will be described with reference to FIG. FIG. 7 is a flowchart showing the procedure of the accounting process according to this embodiment.
First, the customer reads the two-dimensional code printed on the payment receipt 50 using the scanner unit 304 of the accounting POS register 30 (step S200). The scanner unit 304 optically reads the two-dimensional code printed on the payment receipt 50. Next, the CPU 301 (registration means) registers the product information of the product purchased by the customer (step S210). Specifically, the CPU 301 reads the product information stored in the product master using the product code stored in the two-dimensional code read by the scanner unit 304, and stores the product information in the RAM 203. At this time, the CPU 301 adds the purchase points of the product. Further, the CPU 301 calculates the total amount by adding the prices of the products. In addition, the CPU 301 adds the number of products with the same product code. As a result, the CPU 301 creates purchase details that are information on the products purchased by the customer (registered by the registration means).

  Next, a process for determining whether or not the two-dimensional code is forgotten to be read will be described. When the “checkout” button is pressed, the CPU 301 determines whether or not all the two-dimensional codes have been read (no forgetting to read) (step S220). If there is a two-dimensional code that has not been read (step S220: No), the process branches to step S230. On the other hand, if the CPU 301 determines that all the two-dimensional codes have been read (step S220: Yes), the process proceeds to step S240. For example, two two-dimensional codes are printed on the payment receipt 50, and one of the two two-dimensional codes is read by the scanner unit 304, and the customer clicks the “account” button. When is pressed, the CPU 301 determines that one two-dimensional code has not been read.

  Specifically, the CPU 301 determines whether or not there is a two-dimensional code that is not read based on the fraction assigned to each two-dimensional code printed on the payment receipt 50. At this time, for each two-dimensional code, the total number of two-dimensional codes printed on the settlement receipt 50 is used as a denominator, and a fraction “object 2” using the target two-dimensional code indicating what number two-dimensional code is the numerator. "Dimension code / total number" (for example, 1/2, 2/2) is stored. Specifically, every time the CPU 301 reads the two-dimensional code, the CPU 301 stores the fraction in the two-dimensional code reading count area of the RAM 303. Then, the CPU 301 compares the value stored in the two-dimensional code reading count area of the RAM 303 with the fraction (for example, 1/2, 2/2) included in the two-dimensional code, and the two-dimensional code that has not been read. Determine if there is a code. For example, when only “1/2” is stored in the two-dimensional code reading count area, there are two two-dimensional codes from the denominator “2” of the stored fraction “1/2”. It is determined that a two-dimensional code including “/ 2” has not been read.

  In the case of branching from step S220 to No, the CPU 301 causes the display unit 305 to display a message alerting the customer to read the two-dimensional code that has been forgotten to be read (step S230). For example, the CPU 301 causes the display unit 305 to display “There is a two-dimensional code that has not been read”.

  Next, the CPU 301 counts the number of registered merchandise items (hereinafter referred to as the number of registered merchandise items) in the purchase details stored in the RAM 303 (step S240). At this time, the CPU 301 collects one item for the same item code as one item. Then, the CPU 301 displays purchase details on the display unit 305 based on the number of registered merchandise items counted in step S240 (step S250). Specifically, the CPU 301 causes the display unit 305 to display a list of product names, number, discount discount, price, etc. of registered products. Details of the display of the purchase details will be described later. At this time, the CPU 301 determines the number of items and the character size to be displayed in the list based on the display setting table and the display pattern table. That is, the CPU 301 displays the purchase details in a display pattern in which the number of registered merchandise items matches the conditions of the display setting table. Specifically, when the number of registered merchandise items is 10 or less, the CPU 301 selects the display pattern 1 in the display setting table shown in FIG. The character size is set to “Large”. On the other hand, if the number of registered product items is 11 or more, the CPU 301 selects the display pattern 2 in the display setting table shown in FIG. “Small”. That is, the CPU 301 (character size determining means) determines the number of items and the character size to be displayed in the list in the purchase details based on the number of registered product items (the number of items of products registered by the registration means). The display unit 305 (display unit) displays the purchase details in the character size determined by the character size determining unit.

  Next, the CPU 301 determines whether or not a display switching button (change operation means, display number change operation means) has been pressed (step S260). If the display switching button is pressed, the process branches to step S270. On the other hand, if the display switching button has not been pressed, the process proceeds to step S280.

  In the case of branching from step S260 to Yes, the CPU 301 changes the character size in the purchase details displayed on the display unit 305 and the number of items in the list (step S270). That is, when the display switching button is pressed, the CPU 301 cyclically switches the display pattern in the display pattern table. For example, the CPU 301 switches to 2 when the currently displayed display pattern is 1, and switches to 1 when the currently displayed display pattern is 2. Specifically, if the number of items in the currently displayed list is 20, the CPU 301 changes the number of items in the list to 10 and the character size to “large”. On the other hand, when the number of items in the list is 10, the CPU 301 changes the number of items in the list to 20 and the character size to “small”. In this embodiment, the number of items and the character size are set in the display pattern table, but only the number of items may be set in the display pattern table. In this case, when the display switching button is pressed, the CPU 301 changes the number of items based on the display pattern table, and determines the character size based on the number of items. That is, when the number of cases is changed by the display number changing operation means, the CPU 301 (character size determining means) determines the character size based on the number of cases. Further, when the character size is changed by the change operation means, the display unit 305 (display means) displays the purchase details at the character size. Further, when the number of cases is changed by the display number changing operation means, the display unit 305 (display means) displays the purchase details of the number of cases with the character size determined by the character size determining means.

  Next, the CPU 301 performs accounting (step S280). Specifically, the CPU 301 causes the display unit 305 to display a “cash accounting” button and a “card accounting” button. The customer confirms the subtotal amount and the total amount displayed on the display unit 305, selects an accounting method by selecting and pressing either the “cash accounting” button or the “card accounting” button. The display unit 305 outputs information on the accounting method selected by the customer to the CPU 301. The CPU 301 displays an instruction to the customer on the display unit 305 based on the input accounting method information. Thereafter, the customer completes the accounting according to the instruction displayed on the display unit 305. After completion of the accounting, the CPU 301 causes the printing unit 309 to print the accounting receipt that the customer takes home. In addition, it is good also considering the receipt on which the two-dimensional code was printed as the receipt after accounting, without issuing the accounting receipt.

Next, a display screen displayed on the display unit 305 will be described with reference to FIGS. FIG. 8 is a schematic diagram illustrating a display example of the ten-item display screen 100 according to the present embodiment.
In step S250 described above, when the number of registered merchandise items is 10 or less, the CPU 301 selects the display pattern 1 according to the conditions of the display setting table shown in FIG. 4 and displays the 10 display screen 100 on the display unit 305. The ten-item display screen 100 includes a list 11 of registered products, a page number 12, a total price 13 of registered products, a total score 14 of registered products, and a discount total 15 that is the total of the discounted amounts of discounted products. Then, a discount reason 16 for displaying the reason for discount and a checkout button 17 are displayed. Here, in the registered product list 11, the product name, the number, the discount, which is a discount or discount amount, and the amount of money are displayed in a list. The page number 12 displays the page number of the currently displayed page. For example, when the number of registered product items is 10 or less, “1/1” is displayed in the page number 12.

FIG. 9 is a schematic diagram illustrating a display example of a 20-case display screen 200 according to the present embodiment.
In step S250 described above, when the number of registered merchandise items is 11 or more, the CPU 301 selects the display pattern 2 according to the conditions of the display setting table shown in FIG. 4 and displays the 20 display screen 200 on the display unit 305. The 20-item display screen 200 includes a list 21 of registered products, a page number 22, a total price 23 of registered products, a total score 24 of registered products, and a discount total 25 that is a total of discount prices of discount target products. Then, a discount reason 26 for displaying the reason for discount, a checkout button 27, a display switch button 28, an upper button 29a, and a lower button 29b are displayed. Here, the page number 22 displays the page number of the currently displayed page. For example, when the number of registered merchandise items is 20 or less, which is the number of items in display pattern 2, “1/1” is displayed on page number 22. On the other hand, when the number of registered product items is 21 or more, the number X obtained by dividing the number of registered product items by 20 which is the number of items in display pattern 2 is the denominator, and the currently opened page Y becomes the numerator, and the page number 22, “Y / X” is displayed. When the display switching button 28 is pressed, the CPU 301 changes the registered product to be displayed in the list 21 to 10 items in the display pattern 1 and displays a 20-10 case display screen described later on the display unit 305. . The upper button 29a and the lower button 29b are displayed when the number of registered product items is larger than the number of items in the display pattern table shown in FIG. When the upper button 29 a or the lower button 29 b is pressed, the CPU 301 changes the registered product displayed in the list 21. Specifically, when the up button 29a is pressed, the CPU 301 scrolls up the registered products to be displayed in the list 21 in page (screen) units. When the down button 29b is pressed, the registered product displayed in the list 21 is scrolled down by page (screen).

FIG. 10 is a schematic diagram illustrating a display example of the 20-10 case display screen 300 according to the present embodiment.
When the display switching button 28 is pressed in step S260 described above, the CPU 301 displays the 20-10 case display screen 300 on the display unit 305. The 20-10 case display screen 300 includes a list 31 of registered products, a page number 32, a total amount 33 of registered products, a total score 34 of registered products, and a discount that is the sum of discounted amounts of discounted products. A total 35, a discount reason 36 for displaying the reason for discount, a checkout button 37, a display switch button 38, an upper button 39a, and a lower button 39b are displayed. Here, the page number 32 displays the page number of the currently displayed page. In the illustrated example, when the display pattern is 2, “1/1” is displayed on the page number 32. On the other hand, when the display switching button 38 is pressed to switch to “Mojiji”, the display pattern is switched to 1, and the number X1 obtained by dividing the number of registered product items by the number of items 10 of the display pattern 1 shown in FIG. Thus, the currently opened page Y1 becomes a numerator, and “Y1 / X1” is displayed in the page number 32.
