Further, a LAN (Local Area Network) line 27 is connected to the communication I / F 14, and a barcode scanner 28 is connected to the scanner I / F 15.

  ROM 11, RAM 12, clock circuit 13, communication I / F 14, scanner I / F 15, keyboard controller 16, display controllers 17 and 18, card reader controller 19, printer controller 20, and HDD 21 are configured by an address bus and a data bus. Connected to the CPU 10 via a bus line 30.

  The ROM 11 stores fixed data such as an operation program executed by the CPU 10. Note that the operation program stored in the ROM 11 includes a random number generation program 110 used in receipt printing.

  The RAM 12 forms various working storage areas corresponding to processing scenes. For example, when printing a receipt, a print data area 120 for storing receipt print data is formed.

  The clock circuit 13 measures the system date and time of the POS terminal 1. The communication I / F 14 controls data transmission / reception with an external device to which the LAN line 27 is connected. The external device is, for example, a store server of a store where the POS terminal 1 is installed.

  The barcode scanner 28 optically reads a barcode attached to a product or the like and outputs a code indicated by the barcode. The scanner I / F 15 takes in the code output from the barcode scanner 28 and notifies the CPU 10 of it.

  The keyboard 22 includes various operation keys such as a numeric key, a PLU (Price Look Up) key, a subtotal key, and a deposit / current total key, and outputs a key signal corresponding to the pressed operation key. The keyboard controller 16 captures a key signal output from the keyboard 22 and notifies the CPU 10 of it.

  The cashier display 23 is composed of an LCD (Liquid Crystal Display) and a touch panel provided on the display surface of the LCD, and the housing of the POS terminal 1 so that the display surface faces the standing position side of the cashier. Is attached. The display controller 17 displays various types of information on the cashier display 23 in accordance with commands from the CPU 10.

  The customer display 24 is composed of an LCD or a simple display VFD (Vacuum Fluorescent Display) or the like, and is attached to the housing of the POS terminal 1 so that its display surface faces the standing position of the customer who is paying. Yes. The display controller 18 displays various types of information on the customer display 24 in accordance with instructions from the CPU 10.

  The card reader 25 is a magnetic card reader or an IC card reader that reads information from various cards such as a credit card and a point card. The card reader controller 19 captures information read from the card by the card reader 25 and notifies the CPU 10 of the information.

  The receipt printer 26 is a thermal printer that issues a receipt obtained by printing accounting details on a receipt sheet from a receipt issuing port (not shown) provided in the housing of the POS terminal 1. The printer controller 20 drives the receipt printer 26 in response to a command from the CPU 10 and issues a receipt based on the print data stored in the print data area 120 of the RAM 12.

  The HDD 21 stores a PLU file 211 and a marker position table 212 in addition to an OS (Operating System) file and application files. The PLU file 211 is configured by combining a record in which product data including the product name, unit price, and the like is associated with a PLU code, which is a product identifier, for the product handled in the store. Details of the marker position table 212 will be described later with reference to FIG.

[Receipt printer and receipt]
FIG. 2 is a schematic diagram showing the relationship between the print head 261 of the receipt printer 26 and the receipt paper 263. The print head 261 has a heating element group 262 in which a number of heating elements are arranged in a line. The receipt paper 263 is continuous paper supplied from a paper roll, and is conveyed in a conveyance direction (indicated by an arrow in the drawing) perpendicular to the arrangement direction of the heating element groups 262 by a conveyance mechanism (not shown). When each heating element is selectively heated in conjunction with this conveyance, the receipt paper 263, which is thermal paper, partially develops color, and characters, figures, and the like are printed. When printing is completed, the printing portion of the receipt paper 263 is cut off by a cutter mechanism (not shown).

  Here, the arrangement direction of the heating element groups 262 is defined as the X-axis direction, and the conveyance direction of the receipt paper 263 is defined as the Y-axis direction. In the present embodiment, the X-axis direction width of the heating element group 262 is longer than the same width of the receipt paper 263. Therefore, printing can be performed on the entire area of the receipt paper 263.

  An example of the print data of the receipt printed by the receipt printer 26 having such a configuration is shown in FIG. The right side of the print data 300 shown in the X-axis direction coincides with the right side of the receipt paper 263 in the X-axis direction during printing, and the left side of the print data 300 in the X-axis direction corresponds to the left side of the receipt paper 263 in the X-axis direction during printing. Matches. In such print data 300, the date of accounting (“XXX year XX month XX date”), the product name and unit price of the accounting target product (“cigarette ¥ XXX”, etc.), and the subtotal amount (“subtotal ¥ XXXX”) ), Current total amount (“current total ¥ XXXX”), and accounting time, such as accounting time (“XXX XX hours XX minutes”), are arranged.

  In addition to these pieces of information, the print data 300 includes one rectangular and solid black marker M. This marker M is arranged at any one of positions P1, P2,... P9 defined so as to be in contact with the right side of the print data 300 in the X-axis direction. The position P1 is positioned at the lower right corner of the print data 300, and the position P9 is positioned at the upper right corner. Between the positions P1 and P9 defined in this way, the positions P2 to P8 are positioned at equal intervals.

  In addition, what is necessary is just to change the space | interval of each position P1-P9 according to the length of a receipt. That is, when information indicating accounting details and the like is arranged and the length of the receipt in the Y-axis direction is determined, the positions P2 to P8 are positioned so that adjacent ones are equally spaced based on the length.

  An example of the data structure of the marker position table 212 is shown in FIG. The marker position table 212 is configured by associating the positions “P1”, “P2”,... “P9” with the single-digit numbers “1”, “2”,. The arrangement position of the marker M is determined using the marker position table 212 having such a data structure and a single digit random number obtained by executing the random number generation program 110. That is, in the marker position table 212, the position associated with the number having the same value as the generated random number is the arrangement position of the marker M.

[Accounting]
Next, accounting processing will be described.
When the PLU key provided on the keyboard 22 is pressed, the CPU 10 executes the operation program stored in the ROM 11 and starts the accounting process. FIG. 5 shows a flowchart of processing executed by the CPU 10 in accounting processing.

  In this process, first, the CPU 10 accepts registration of a product that a customer intends to purchase (step S101). At this time, when the cashier reads the barcode attached to the product using the barcode scanner 28, the PLU code indicated by the barcode is input via the scanner I / F 15. When the PLU code is input, the CPU 10 reads the product data associated with the PLU code from the PLU file 211 and stores it in the RAM 12. Each product that the customer intends to purchase is registered by the process of this flow.

  When the customer finishes registering all the products to be purchased, the cashier depresses the subtotal key provided on the keyboard 22. When the subtotal key is pressed, the CPU 10 calculates the subtotal amount and the current total amount based on the product data stored in the RAM 12, and displays the cashier display 23 and the customer display 24 via the display controllers 17 and 18. To display the subtotal amount and the current total amount, and accept payment of the price (step S102). At this time, when the cashier inputs the deposit amount from the customer by operating the numeric keys of the keyboard 22 and depresses the deposit / cash key, the CPU 10 calculates the difference between the deposit amount and the price as a change amount. Then, the deposit amount and the change amount are displayed on the cashier display 23 and the customer display 24 via the display controllers 17 and 18. Looking at this display, the cashier returns the change to the customer.

  When the deposit / current total key is pressed, the CPU 10 arranges the accounting details, etc. using the product data stored in the RAM 12, the subtotal amount, the current total amount, and the date and time measured by the clock circuit 13. The receipt print data is generated and stored in the print data area 120 of the RAM 12 (step S103).

  Thereafter, the CPU 10 executes the random number generation program 110 stored in the ROM 11 to generate a one-digit random number (step S104). Then, the number having the same value as the generated random number is searched from the marker position table 212, and the position associated with the found number is determined as the arrangement position of the marker M (step S105).

  When the arrangement position of the marker M is determined, the CPU 10 adds the marker M to the determined arrangement position of the print data stored in the print data area 120 and completes the print data (step S106). When the print data is thus completed, the CPU 10 causes the printer controller 20 to drive the receipt printer 26, and prints and issues a receipt based on the print data stored in the print data area 120 (step S107). This completes a series of accounting processes.

  Note that the processing in step S104 constitutes a random number generation means, and the processing in steps S105 and S106 constitutes a position changing means for selectively changing the position where the marker M is attached to the side of the receipt that is a printed matter.

[Action]
The operation will be described.
FIG. 6 is a schematic diagram showing a plurality of receipts issued in separate accounting processes. Here, as an example, eight receipts 401, 402,... 408 having the same size are shown. In the receipts 401, 403, and 406, “1” is generated as a random number (step S104), and the position “P1” associated with the number “1” in the marker position table 212 is determined as the arrangement position of the marker M ( In step S105, a marker M is added to the position P1 in the print data stored in the print data area 120 (step S106), and printing is performed based on the print data (step S107). In the receipts 402, 405, and 408, “5” is generated as a random number (step S104), and the position “P5” associated with the number “5” in the marker position table 212 is determined as the arrangement position of the marker M ( In step S105, a marker M is added to the position P5 in the print data stored in the print data area 120 (step S106), and printing is performed based on the print data (step S107). In the receipts 404 and 407, “9” is generated as a random number (step S104), and the position “P9” associated with the number “9” in the marker position table 212 is determined as the arrangement position of the marker M (step S105). The marker M is added to the position P9 in the print data stored in the print data area 120 (step S106), and printing is performed based on the print data (step S107).

  FIG. 7 shows a schematic diagram when the receipts 401, 402, 403, 404, 405, 406, 407, and 408 are overlapped in this order and viewed from the side of the end portion side where the marker M is printed. In this way, since each of the receipts 401 to 408 is provided with the marker M that is positioned based on a random number, it is possible to easily determine how many receipts are in this bundle.

  Here, it is assumed that one of the receipts and the lower receipt are in close contact with each other, and when the upper receipt is picked up, the lower receipt is attached to the back surface thereof. Even in such a case, if the marker M is confirmed from the side, it can be noticed that two receipts are overlapped due to the difference in the printing position.

  Further, in particular, in the present embodiment, the marker M is printed in a rectangular solid black, so that if the lower receipt is in close contact with any receipt, the marker M of the lower receipt is transparent from the printing surface of the upper receipt. Easy to see. It can be noticed that two receipts are overlapped also by checking the marker M that is seen through.

(Second Embodiment)
A second embodiment will be described.
This embodiment is different from the first embodiment in that a counter that changes the count value every time a receipt is printed is provided, and the arrangement position of the marker M is changed using the count value of this counter instead of a random number. Different.

  In the RAM 12 in the present embodiment, a counter area for counting numerical values from “1” to “9” is generated. This counter area is generated, for example, immediately after the POS terminal 1 is turned on and the system is started, and is deleted when the system is shut down.

  FIG. 8 shows a flowchart of processing executed by the CPU 10 in the accounting processing in this embodiment. When the accounting process is started, the CPU 10 accepts registration of a product (step S201), accepts payment of a price (step S202), and prints a receipt in which information such as accounting details is arranged, as in the first embodiment. Data is generated (step S203).

  Subsequently, the CPU 10 refers to the counter of the RAM 12 and acquires the count value (step S204). Then, the number having the same value as the acquired count value is searched from the marker position table 212, and the position associated with the found number is determined as the arrangement position of the marker M (step S205).

  When the arrangement position of the marker M is determined, the CPU 10 adds the marker M to the determined arrangement position of the print data stored in the print data area 120, thereby completing the print data (step S206). When the print data is thus completed, the CPU 10 causes the printer controller 20 to drive the receipt printer 26, and prints and issues a receipt based on the print data stored in the print data area 120 (step S207).

After the receipt printer 26 prints and issues the receipt, the CPU 10 increments the count value of the counter by one (step S208). However, when the count value of the counter is “9”, the count value is returned to “1”. A series of transaction processing is completed by the processing in step S207.
Note that the processes in steps S205 and S206 constitute position changing means in the present embodiment.

  As described above, in this embodiment, the count value of the counter is changed every time a receipt is issued, and the arrangement position of the marker M is changed based on the count value. Even if it does in this way, since the arrangement position of the marker M is changed for every receipt, there exists an effect similar to the said embodiment.

(Third embodiment)
Next, a third embodiment will be described.
This embodiment is different from the above embodiments in that the arrangement position of the marker M is changed using the date and time counted by the clock circuit 13.

  An example of the data structure of the marker position table 212a in the present embodiment is shown in FIG. The marker position table 212a is configured by associating positions “P1”, “P2”,... “P9” with “condition 1”, “condition 2”,. . Each of the conditions 1 to 9 may indicate, for example, the business hours of the store divided into nine parts as long as one is established for one date and time, or indicate different business days of the store. It may be a thing.

  FIG. 10 shows a flowchart of processing executed by the CPU 10 in the accounting processing in the present embodiment. When the accounting process is started, the CPU 10 accepts the registration of the product (step S301), accepts the payment of the price (step S302), and prints the receipt in which information such as accounting details is arranged, as in the above embodiments. Is generated (step S303).

  Subsequently, the CPU 10 acquires the current date and time from the clock circuit 13 (step S304). Then, the acquired date and time are compared with the conditions 1 to 9 in the marker position table 212a, and the position associated with the established condition is determined as the arrangement position of the marker M (step S305).

When the arrangement position of the marker M is determined, the CPU 10 adds the marker M to the determined arrangement position of the print data stored in the print data area 120, thereby completing the print data (step S306). When the print data is thus completed, the CPU 10 causes the printer controller 20 to drive the receipt printer 26, and prints and issues a receipt based on the print data stored in the print data area 120 (step S307). This completes a series of accounting processes.
Note that the processes in steps S305 and S306 constitute position changing means in the present embodiment.

  As described above, in the present embodiment, the arrangement position of the marker M is changed according to the date and time counted by the clock circuit 13. Even in this case, since the arrangement position of the marker M is changed for each time or each date, the same effect as the above embodiment can be obtained.

(Fourth embodiment)
Next, a fourth embodiment will be described.
This embodiment is different from the above embodiments in that the markers M1, M2, and M3 whose arrangement positions are fixed are printed on the receipt in addition to the marker M.

  An example of print data of a receipt printed in this embodiment is shown in FIG. In the illustrated print data 310, the same information as the print data 300 shown in FIG. 3 is arranged. However, markers M1, M2, and M3 whose positions do not change are arranged at the upper left corner, lower left corner, and upper right corner of the print data 310, respectively. The position P1 is positioned at the lower right corner of the print data 310. Between the position P1 defined in this way and the arrangement position of the marker M3, positions P2 to P9 are positioned at equal intervals so as to contact the right side in the X-axis direction.

  In the accounting process, of the positions P1 to P9 in the print data 310, a position determined using a random number as in the first embodiment, and a position determined using a counter as in the second embodiment. Alternatively, as in the third embodiment, the marker M is arranged at a position determined using the date and time, and a receipt on which the markers M, M1, M2, and M3 are printed is issued.

  As described above, in this embodiment, in addition to the marker M whose arrangement position varies, the markers M1, M2, and M3 whose arrangement positions are fixed at the three corners are printed on the receipt. Even if it does in this way, there exists an effect similar to each said embodiment.

  In addition, when a receipt issued by the POS terminal 1 and a receipt issued by another POS terminal or the like are in close contact, the overlap is noticed regardless of which side the receipt is viewed from. be able to.

(Fifth embodiment)
Next, a fifth embodiment will be described.
This embodiment is different from the above embodiments in that the marker M is printed on both ends of the receipt in the X-axis direction.

  An example of print data of a receipt printed in this embodiment is shown in FIG. In the illustrated print data 320, the same information as the print data 300 shown in FIG. 3 is arranged. However, positions P1, P2,... P9 are defined so as to be in contact with the right side and the left side at both ends in the X-axis direction. The marker MR is arranged at any one of the positions P1 to P9 in contact with the right side, and the marker ML is arranged at any of the positions P1 to P9 in contact with the left side.

  The accounting process in the present embodiment proceeds in the same flow as in the first embodiment. However, the random number generation program 110 in this embodiment is configured to generate a two-digit random number. Therefore, in the process of step S104, the CPU 10 generates a two-digit random number. In step S105, the CPU 10 searches the marker position table 212 for a number having the same value as any one digit of the generated random number, and determines the position associated with the found number as the marker MR placement position. To do. Further, a number having the same value as the value of the other digits of the generated random number is searched from the marker position table 212, and the position associated with the found number is determined as the arrangement position of the marker ML.

  Thereafter, in the process of step S106, the CPU 10 completes the print data by adding the markers MR and ML to the determined arrangement position of the print data stored in the print data area 120, and receives the receipt in the printer controller 20 in the process of step S107. The printer 26 is driven to print and issue a receipt based on the print data stored in the print data area 120.

  As described above, in the present embodiment, the markers MR and ML are printed while changing the position with random numbers on the left and right ends in the X-axis direction of the receipt. By doing so, it is possible to notice the close contact of a plurality of receipts even when any end portion on which the markers MR and ML are printed is viewed from the side.

(Sixth embodiment)
Next, a sixth embodiment will be described.
This embodiment is different from the above embodiments in that the width of the heating element group 262 of the receipt printer 26 is shorter than the width of the receipt paper 263.

  FIG. 13 is a schematic diagram for explaining the relationship between the print head 261 of the receipt printer 26 and the receipt paper 263 in the present embodiment. As described above, the X-axis direction width of the heating element group 262 in the present embodiment is shorter than the same width of the receipt paper 263. Therefore, the marker M cannot be printed so as to contact the left side in the X-axis direction of the receipt or to contact the right side.

  Therefore, in the present embodiment, positions P1 to P9 for defining the marker M so as to contact the lower side in the Y-axis direction of the print data are defined. An example of the print data in which the positions P1 to P9 are defined in this way is shown in FIG. In the illustrated print data 330, the same information as the print data 300 shown in FIG. 3 is arranged. Two broken lines attached in the Y-axis direction in the figure indicate the width of the heating element group 262. The position P1 is positioned so as to be in contact with the lower side in the Y-axis direction and the left dashed line, and the position P9 is positioned so as to be in contact with the lower side in the Y-axis direction and the right dashed line. Between the positions P1 and P9 defined in this way, positions P2 to P8 are positioned at equal intervals so as to be in contact with the lower side in the Y-axis direction. In addition, since the width of the end portion in the Y-axis direction is usually shorter than the width of the end portion in the X-axis direction, the size of the marker M is made smaller than those shown in the above embodiments. Receipts printed based on such print data 330 are cut by the cutter mechanism along the lower side in the Y-axis direction. Therefore, the marker M is printed in contact with the lower side of the receipt.

  In the accounting process, of the positions P1 to P9 in the print data 330, a position determined using a random number as in the first embodiment, and a position determined using a counter as in the second embodiment. Alternatively, as in the third embodiment, the marker M is arranged at a position determined using the date and time, and a receipt on which the marker M is printed is issued.

  As described above, in this embodiment, the marker M is printed so as to be in contact with the lower side of the receipt in the Y-axis direction. Even in this way, it is possible to notice the close contact of a plurality of receipts by looking at the end on which the marker M is printed from the side.

(Modification)
Note that the configuration disclosed in each of the embodiments can be embodied by appropriately modifying each component in the implementation stage. Specific examples of modifications are as follows.

(1) In each of the above embodiments, the case where a marker is attached to a receipt issued from the POS terminal 1 is exemplified. However, the configuration disclosed in each of the embodiments can be modified and applied to other types of apparatuses. For example, the configuration disclosed in each of the above embodiments may be applied to a payment terminal that processes payment by credit card. In this case, a marker may be printed on each of a store copy slip, a customer slip, and a credit carrier slip issued each time a settlement is made from the settlement terminal, or one or two slips. Markers may be printed on.

(2) In the first embodiment, the marker arrangement position is changed according to the random number. In the second embodiment, the marker arrangement position is changed every time a receipt is issued. In the third embodiment, the date and time are changed. The case where the arrangement position of the marker is changed accordingly is illustrated. However, the marker placement position may be changed based on other conditions. For example, the marker placement position may be changed every time the number of issued receipts reaches a predetermined number of times, or the marker placement position may be changed according to the number of products purchased by the customer. Alternatively, the marker arrangement position may be changed according to the subtotal amount or the current total amount.

(3) In the fifth embodiment, the case where the arrangement position of two markers is changed is exemplified, and in the other embodiment, the case where the arrangement position of one marker is changed is exemplified. However, a larger number of markers may be printed while changing their arrangement positions. For example, four markers in contact with each of the four sides of the receipt may be printed while changing their arrangement positions, or a plurality of markers in contact with any one side may be printed while changing their arrangement positions.

(4) In each of the above embodiments, the case where the marker arrangement position is changed among the positions P1 to P9 is exemplified. However, the marker arrangement position may be changed in a larger or smaller number of positions. Moreover, the arrangement positions of the markers may be defined so that the adjacent arrangement positions partially overlap each other, or obtained by using a predetermined calculation formula without defining the arrangement positions such as the positions P1 to P9. You may make it arrange | position a marker in a position.

(5) In each of the above embodiments, the case of printing a rectangular and solid black marker has been exemplified. However, the shape of the marker may be changed like a circle, a star, a triangle, or other polygons, or only the border may be used without painting the inside of the marker.

Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention.
