Description

  The present invention relates to a POS system, a receipt switching method, and a receipt switching program.

  In stores such as supermarkets and mass retailers, a POS (Point Of Sale) system has been introduced as an accounting system. In the POS system, the POS terminal issues a receipt for each transaction. Roll paper is used as the receipt paper used for issuing such a receipt. The stock of the roll paper is managed at the store.

  If there is a large amount of roll paper in stock, it will be possible to prevent out of stock, but it will be more expensive. On the other hand, if the amount of roll paper stock is small, the cost can be reduced, but the stock may run out and the POS terminal may not be able to issue a receipt.

  For example, Patent Document 1 proposes a receipt journal printer that issues a receipt with compressed printing in order to efficiently use receipt paper.

Japanese Patent Laid-Open No. 7-148988

  As described above, if the roll paper stock is large, the cost is excessive, and if the roll paper stock is small, the stock may be out of stock and the POS terminal may not be able to issue a receipt. Therefore, it is desirable that the stock amount of roll paper is an appropriate stock amount that can achieve both cost reduction and prevention of out of stock. However, in a store, since it is necessary for the POS terminal to issue a receipt securely, it is necessary to have an excessive stock of roll paper.

  For example, when the proposed receipt journal printer is used, the amount of receipt paper used is reduced, and out of stock can be suppressed. However, there are cases where the convenience of the user is impaired with the receipt paper compressed in printing.

  The present invention has been made in view of the above points, and has a POS system, a receipt switching method, and a receipt capable of suppressing the stock amount of roll paper and suppressing the out of stock while ensuring the convenience of the user. Provide a switching program.

In order to solve the above problems, the present invention provides a POS system having a POS terminal and a POS server.
The POS terminal includes a ticket issuing unit and a ticket issuing control unit. The ticket issuing unit displays the transaction information in a first display that displays transaction information related to the transaction in the first display mode, and a second display mode in which the display range is smaller than the first display mode, and a receipt length shorter than the first receipt. The second receipt can be cut out from the roll paper and issued. The ticketing control unit performs ticketing control for issuing the first receipt or the second receipt from the ticketing unit based on an instruction from the POS server. The POS server includes an inventory management unit, an evaluation unit, and an instruction unit. The inventory management unit manages the inventory amount of roll paper used by the POS terminal and the delivery date of the already ordered roll paper. The evaluation unit evaluates the risk of running out of stock of roll paper based on the inventory amount and the delivery date. The instructing unit instructs the ticketing control unit to switch the ticketing from the first receipt to the second receipt based on the evaluation.

  In order to solve the above problems, the present invention provides a receipt switching method in which a computer performs the following processing, and a receipt switching program that causes a computer to execute the processing described below.

  The computer manages the amount of roll paper stock used by the POS terminal to issue receipts and the delivery date of the already ordered roll paper, and evaluates the risk of roll paper out of stock based on the stock amount and delivery date. Based on the above, the transaction information is displayed in a second display mode in which the display range is smaller than the first display mode from the first receipt in which the transaction information related to the transaction is displayed in the first display mode, and the receipt length is shorter than the first receipt. Instructs switching of ticketing to the second receipt.

  According to the POS system, the receipt switching method, and the receipt switching program, it is possible to suppress the stock amount of roll paper and prevent out of stock while ensuring convenience for the user.

Hereinafter, embodiments will be described with reference to the drawings.
[First embodiment]
FIG. 1 is a conceptual diagram of a POS system in the first embodiment.

  The POS system 1 is an accounting system installed in a retail store or the like. The POS system 1 is a system that manages the stock of roll paper used to issue a receipt, and switches the receipt issued by the POS terminal 3 to a receipt that allows efficient use of the roll paper when the stock of roll paper decreases. is there. The POS system 1 includes a POS server 2 and a POS terminal 3.

  The POS terminal 3 is a terminal that registers a product as a purchased product. The POS terminal 3 accounts for the registered purchased product and finalizes the transaction. The POS terminal 3 issues a ticket by cutting the first receipt 9 or the second receipt 10 on which transaction information relating to the confirmed transaction is printed from the roll paper attached to the POS terminal 3. Transaction information is information necessary for accounting for transactions. The transaction information is information including, for example, a product name, a unit price, a quantity, a total amount, and the like. The POS terminal 3 includes a ticket issuing unit 8 and a ticket issuing control unit 7.

  The ticket issuing unit 8 can issue a ticket by cutting the first receipt 9 and the second receipt 10 from the roll paper. The 1st receipt 9 is a receipt which displays transaction information by the 1st display mode 9a. The first display mode 9a is a display mode in consideration of user convenience (visibility). The 1st display mode 9a is a display mode in which the size of the character of transaction information, the space between lines, etc. were set as a moderate size, for example.

  The second receipt 10 displays the transaction information in the second display mode 10a having a display range smaller than that of the first display mode 9a. The second receipt 10 is a receipt having a receipt length shorter than that of the first receipt 9. Therefore, the ticket issuing unit 8 can use the roll paper more efficiently when the second receipt 10 is issued than when the first receipt 9 is issued. The second display mode 10a is a display mode in which the display range in which transaction information is displayed is smaller than the first display mode 9a in order to shorten the receipt length. The second display mode 10a is a display mode in which, for example, the character size and the space between lines are set smaller than the first display mode 9a. Therefore, when the ticket issuing unit 8 issues the second receipt 10 that displays the transaction information in the second display mode 10a, the convenience of the user may be impaired. Therefore, it is desirable that the ticket issuing unit 8 issues the first receipt 9 as much as possible in order to ensure the convenience of the user. Accordingly, the ticket issuing unit 8 issues the first receipt 9 at the normal time, and issues the second receipt 10 when the stock is likely to run out.

The ticketing control unit 7 performs ticketing control for issuing the first receipt 9 or the second receipt 10 from the ticketing unit 8 based on an instruction from the instruction unit 6.
The POS server 2 is a server that manages the POS system 1. The POS server 2 manages stock information of roll paper used for issuing a receipt issued by the POS terminal 3 in transaction accounting. Transactions include, for example, purchasing products at retail stores such as supermarkets and convenience stores, and using services at entertainment facilities. The roll paper stock information includes, for example, the roll paper stock amount 4a and the roll paper delivery date 4b. Further, the POS server 2 evaluates the risk of out-of-stock based on the roll paper stock amount 4a and the roll paper delivery date 4b. Then, the POS server 2 instructs the ticket issuing control unit 7 to issue the first receipt 9 or the second receipt 10 based on the evaluation of the out-of-stock risk.

  The POS server 2 includes an inventory management unit 4, an evaluation unit 5, and an instruction unit 6. The inventory management unit 4 manages the inventory amount 4a of roll paper used by the POS terminal 3 and the delivery date 4b of the roll paper already ordered. The roll paper stock amount 4a is the total number of roll papers that are not yet used. The roll paper stock amount 4a may or may not include roll paper attached to the POS terminal 3. The roll paper delivery date 4b is a scheduled date on which the roll paper stock is delivered.

  The evaluation unit 5 evaluates the roll paper out-of-stock risk 5a based on the roll paper stock amount 4a and the roll paper delivery date 4b. The out-of-stock risk 5a is a risk that the out-of-stock will occur. The out-of-stock risk 5a increases when the possibility of out-of-stock is high, and decreases when the possibility of out-of-stock is low. The risk of running out of stock 5a increases as the stock quantity 4a decreases, because the possibility of running out of stock increases. Further, since the roll paper is newly delivered, the evaluation unit 5 cannot appropriately evaluate the out-of-stock risk 5a as the delivery date 4b is closer.

  Therefore, the evaluation unit 5 evaluates the out-of-stock risk 5a as “high risk” when the stock amount 4a is less than the predetermined amount and the number of days until the delivery date 4b is equal to or greater than the predetermined number of days. Further, the evaluation unit 5 evaluates the out-of-stock risk 5a as “low risk” when the stock quantity 4a is equal to or greater than the predetermined quantity and the number of days until the delivery date 4b is equal to or greater than the predetermined number of days. Then, the evaluation unit 5 does not evaluate the out-of-stock risk 5a when it is less than the predetermined number of days until the delivery date 4b.

  The instruction unit 6 instructs the ticketing control unit 7 to switch the ticketing from the first receipt 9 to the second receipt 10 based on the evaluation. The instructing unit 6 instructs the ticketing control unit 7 to switch the ticketing from the first receipt 9 to the second receipt 10 when the evaluating unit 5 evaluates that the out-of-stock risk 5a is high.

  For example, when the inventory amount 4a managed by the inventory management unit 4 is 5 rolls and the delivery date 4b is 10 days later, the evaluation unit 5 evaluates the out-of-stock risk 5a as “high risk”. Then, the instruction unit 6 instructs the ticket issuing control unit 7 to switch the ticket issuing from the first receipt 9 to the second receipt 10.

  According to the POS system 1 described above, the POS server 2 evaluates the out-of-stock risk 5a based on the delivery date 4b and the inventory quantity 4a, and switches the ticket issuing from the first receipt 9 to the second receipt 10 based on the evaluation. To the ticket issuing control unit 7. The POS terminal 3 issues the first receipt 9 or the second receipt 10 based on the instruction received from the POS server 2 by the ticketing control unit 7.

  Therefore, the POS system 1 switches the receipt from the first receipt 9 to the second receipt 10 while issuing the first receipt 9 while ensuring the convenience of the user, and issuing the ticket based on the out-of-stock risk. It is possible to prevent the roll paper from being out of stock.

  In addition, the POS server 2 instructs the POS terminal 3 to switch the ticket issuing to a receipt that efficiently uses roll paper based on the risk of running out of stock, so that an unexpected increase in the amount of roll paper used is taken into account. It is no longer necessary to have an excessive stock of roll paper in advance. Therefore, the POS system 1 can suppress stock of roll paper.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIG. FIG. 2 is a diagram showing a POS system in the second embodiment.

  The POS system 11 is an accounting system installed in a retail store or the like. In the POS system 11, the POS terminal cuts out the roll paper attached to the terminal and issues a receipt for each transaction accounting. The POS system 11 performs efficient use of roll paper by switching the receipt issued by the POS terminal 12 based on an instruction from the POS server 13 when the stock amount of roll paper used for issuing a receipt decreases. System.

The POS system 11 includes a POS server 13 and a plurality of POS terminals 12 connected to the POS server 13 via a network 14.
The POS terminal 12 is a terminal that registers a product as a purchased product. The POS terminal 12 accounts for the purchased purchased product and finalizes the transaction. The POS terminal 12 issues a ticket by cutting out a receipt on which transaction information relating to the confirmed transaction is printed from a roll paper attached to the POS terminal 12. The POS terminal 12 can issue a first receipt and a second receipt. The first receipt is a receipt that displays transaction information in the first display mode. The first receipt is issued when the out-of-stock risk is small (normal time). In the first receipt, the character size, the spacing between lines, and the like are set in consideration of the convenience of the user. A 2nd receipt is a receipt which displays transaction information in the 2nd display mode whose display range is smaller than the 1st display mode. The second receipt is issued when an out of stock is likely to occur (in an emergency). For example, in the second display mode, the size of characters printed in the first display mode and the interval between lines are set to be small, and transaction information is displayed in a display mode having a display range smaller than that of the first display mode. Since the transaction information is displayed in the second display mode having a display range smaller than that of the first display mode, the second receipt can have a shorter receipt length than the first receipt. Therefore, when the POS terminal 12 issues the second receipt, the roll paper can be used more efficiently than when the first receipt is issued. The first receipt and the second receipt will be described in detail later with reference to FIGS.

  The POS server 13 is a server that manages the POS system 11. The POS server 13 manages information used for evaluating a roll paper out-of-stock risk. The information used for evaluating the out-of-stock risk is, for example, the stock amount of roll paper and the delivery date of roll paper. The POS server 13 evaluates the out-of-stock risk based on the roll paper stock amount and the roll paper delivery date. Then, the POS server 13 gives an instruction to switch the receipt issued by the POS terminal 12 based on the out-of-stock risk evaluation. The POS server 13 instructs the POS terminal 12 to switch the receipt issued by the POS terminal 12 from the first receipt to the second receipt when the out-of-stock risk increases. Then, the POS server 13 instructs the POS terminal 12 to switch the receipt issued by the POS terminal 12 from the second receipt to the first receipt when the out-of-stock risk is reduced.

Next, the POS terminal 12 will be described with reference to FIG. FIG. 3 is a diagram showing a POS terminal in the second embodiment.

  A display 27 and a customer display 28 are connected to the graphic processing device 21e. The display 27 displays a predetermined GUI for performing transaction work. The display 27 is, for example, a liquid crystal display. The display 27 is located below the touch panel 26. The image displayed on the display 27 can be seen by the operator through the touch panel 26. The operator can perform a touch operation on the touch panel 26 while viewing the image displayed on the display 27. The graphic processing device 21e displays images on the screens of the display 27 and the customer display 28 in accordance with instructions from the CPU 21a.

  An automatic change machine 22, a cash drawer 23, an automatic fishing bill machine 24, a keyboard 25, a touch panel 26, and a printer 29 are connected to the input / output interface 21f. Further, the input / output interface 21 f can be connected to a portable recording medium interface that can write information to the portable recording medium 35 and read information from the portable recording medium 35. The input / output interface 21f transmits signals sent from the keyboard 25, the touch panel 26, and the portable recording medium interface to the CPU 21a via the bus 21g.

  The communication interface 21d is connected to the POS server 13 in a connection format such as a LAN (Local Area Network) or a USB (Universal Serial Bus) connection. The communication interface 21d transmits / receives data to / from the POS server 13.

With the hardware configuration as described above, the processing functions of the present embodiment can be realized. The POS server 13 can also be realized with the same hardware configuration.
Note that the POS terminal 12 and the POS server 13 may each be configured to include modules such as an FPGA (Field Programmable Gate Array) and a DSP (Digital Signal Processor), or may not include the CPU 21a. In this case, each of the POS terminal 12 and the POS server 13 includes a nonvolatile memory (for example, an EEPROM (Electrically Erasable and Programmable Read Only Memory), a flash memory, a flash memory type memory card, etc.) and stores module firmware. The nonvolatile memory can write firmware through the portable recording medium 35 or the communication interface 21d. As described above, the POS terminal 12 and the POS server 13 can also update the firmware by rewriting the firmware stored in the nonvolatile memory.

Next, functions provided in the POS system 11 will be described. FIG. 5 is a functional block diagram of the POS system in the second embodiment.
The POS system 11 includes a POS terminal 12 and a POS server 13. When the roll paper is exchanged by the printer 29, the POS terminal 12 detects the exchange of the roll paper and updates the roll paper stock quantity of the roll paper managed by the POS server 13. The POS server 13 evaluates the out-of-stock risk based on the stock amount of roll paper. The POS server 13 instructs the POS terminal 12 to issue the first receipt or issue the second receipt based on the evaluation result of the out-of-stock risk. The POS terminal 12 issues a first receipt or a second receipt based on an instruction from the POS server 13.

  The POS server 13 includes an evaluation unit 41, an evaluation information storage unit 42, a roll stock information storage unit 43, an instruction unit 44, a control state storage unit 45, and a communication unit 46. The POS terminal 12 includes a ticket issuing unit 51, a ticket issuing control unit 52, an exchange detection unit 53, and a communication unit 54.

  The evaluation information storage unit 42 stores information (evaluation information) used by the evaluation unit 41 for evaluating out-of-stock risk. The evaluation information includes, for example, a threshold inventory amount that is a threshold for inventory amount and a threshold delivery date that is a threshold for delivery date. The threshold stock amount and the threshold delivery date are set based on, for example, the variation (dispersion) of the roll paper usage amount in the entire POS system, which is calculated using the roll paper usage amount in the entire POS system for each predetermined period. The When the variation is large, the usage amount is likely to fluctuate, so a large value is set as the threshold stock amount, and a short period is set as the threshold delivery date. By setting the threshold stock amount large in this way, it is possible to more surely prevent out of stock even when a sudden change in the usage amount occurs. Also, by shortening the threshold delivery date, it is possible to prevent out of stock even if a sudden change in usage occurs immediately before the delivery date. The evaluation information held by the evaluation information storage unit 42 will be described in detail later with reference to FIG.

  The roll stock information storage unit 43 stores information (stock information) relating to the stock of roll paper used by the POS terminal 12 to issue a receipt. The roll paper stock information includes, for example, the roll paper stock amount and the roll paper delivery date. The inventory information held by the roll inventory information storage unit 43 will be described later in detail with reference to FIG. In the roll stock information storage unit 43, when the POS terminal 12 detects the replacement of the roll paper, the stock quantity of the roll paper is updated. In the roll stock information storage unit 43, the delivery date of the roll paper is set based on the roll paper order notification. The order notification is performed, for example, by inputting the delivery date of the roll paper ordered by the operator to the POS server 13. The roll stock information storage unit 43 updates the roll paper stock quantity based on the roll paper delivery notification. The delivery notification is performed, for example, when the operator inputs the quantity of roll paper delivered to the POS server 13.

  The evaluation unit 41 evaluates the out-of-stock risk based on the evaluation information in the evaluation information storage unit 42 and the inventory information in the roll stock information storage unit 43. The evaluation unit 41 evaluates that the out-of-stock risk is high when the roll paper stock quantity is smaller than the threshold stock quantity. The evaluation unit 41 evaluates that the out-of-stock risk is small when the roll paper stock amount is equal to or greater than the threshold stock amount. The evaluation unit 41 does not evaluate the out-of-stock risk because the out-of-stock risk cannot be appropriately evaluated when the delivery date is less than the threshold delivery date. Upon receiving the roll paper replacement notification from the replacement detection unit 53, the evaluation unit 41 evaluates the out-of-stock risk. The timing at which the evaluation unit 41 evaluates the out-of-stock risk is not limited to the timing at which the roll paper replacement notification is received. For example, the evaluation unit 41 evaluates the out-of-stock risk at the timing at which the POS server 13 is activated. May be.

  The instruction unit 44 instructs the ticket issuing control unit 52 on the control content based on the evaluation of the evaluation unit 41. The instruction unit 44 issues a ticket switching instruction from the first receipt to the second receipt when the evaluation unit 41 evaluates that the out-of-stock risk is high. Further, the instruction unit 44 receives a roll paper delivery notice (when roll paper is delivered and roll paper is newly stocked), the ticket issuing control unit 52 issues a ticket from the second receipt to the first receipt. Instruct switching.

  The control state storage unit 45 stores information (control state information) on the control state of the ticketing of the receipt performed by the ticketing control unit 52 to the ticketing unit 51. The control state includes a state in which the control for issuing the first receipt is performed and the state in which the control for issuing the second receipt is performed. In the control state storage unit 45, the control state is updated based on the content instructed by the instruction unit 44. In the control state storage unit 45, the control state is updated when the instructing unit 44 instructs the ticketing control unit 52 to switch ticketing from the second receipt to the first receipt. Further, in the control state storage unit 45, the control state is updated when the instruction unit 44 instructs the ticketing control unit 52 to switch the ticketing from the first receipt to the second receipt. The control state information held by the control state storage unit 45 will be described later in detail with reference to FIG.

The communication unit 46 communicates various data with the POS terminal 12 via the communication unit 54.
The ticket issuing unit 51 displays the first receipt for displaying the transaction information in the first display mode and the transaction information in the second display mode having a display range smaller than that of the first display mode, and the receipt length is shorter than the first receipt. The second receipt can be cut out from the roll paper and issued. The ticket issuing unit 51 issues the first receipt at the normal time. The ticket issuing unit 51 issues a second receipt when the out-of-stock risk increases.

  The ticket issuing control unit 52 performs ticket issuing control for issuing a first receipt or a second receipt from the ticket issuing unit 51. The ticket issuing control unit 52 controls the receipt ticket issuing based on the instruction received from the instruction unit 44.

  The replacement detection unit 53 detects replacement of roll paper. The replacement detection unit 53 detects the replacement of the roll paper. Then, the replacement detection unit 53 updates the roll paper stock amount in the roll stock information storage unit 43. The roll paper replacement is detected by, for example, detecting the opening and closing of the lid of the roll paper storage unit of the printer 29. The replacement detection unit 53 detects that the roll paper has been replaced when the lid of the roll paper storage unit is opened and closed. The replacement detection unit 53 is not limited to detecting the replacement of the roll paper by detecting the opening / closing of the lid of the roll paper storage unit of the printer 29, and may be any device that can detect the replacement of the roll paper. For example, the replacement detection unit 53 may detect the replacement of the roll paper based on an operator input to the POS terminal 12, a change in the weight of the roll paper, a change in the thickness of the roll paper, or the like. The communication unit 54 communicates various data with the POS server 13 via the communication unit 46.

  Next, the first receipt and the second receipt will be described with reference to FIGS. FIG. 6 is a diagram illustrating an example of a first receipt in the second embodiment. FIG. 7 is a diagram illustrating an example of a second receipt in the second embodiment.

  The first receipt 60 is a receipt that displays transaction information in the first display mode 61. The 1st display mode 61 is constituted including the goods display part 62, the subtotal display part 63, and the accounting result display part 64, for example.

  The product display unit 62 is a display unit that displays information on purchased products purchased in the transaction (purchased product information). Purchase product information is, for example, product name, quantity, unit price, and privilege information. The privilege information is information related to a privilege granted to the product. Benefits include special sales, discounts, and discounts. Thus, the user can see the product name “carrot”, the privilege “special sale”, and the unit price “¥ 30” by looking at the product display unit 62.

  The subtotal display unit 63 is a display unit that displays subtotal information of transactions. The subtotal information is, for example, a subtotal, a product score, an amount subject to tax, and a consumption tax. Thus, the user can see the subtotal “¥ 540”, the product score “9 points”, the taxable amount “¥ 540”, and the consumption tax “¥ 25” by looking at the subtotal display unit 63.

  The transaction result display unit 64 is a display unit that displays transaction result information of transactions. The accounting result information is, for example, a total amount of transaction, a deposit amount, and change. Thus, the user can see the total amount “¥ 540”, the deposit amount “¥ 1050”, and the change “¥ 510” by looking at the transaction result display section 64.

  The second receipt 65 is a receipt that displays transaction information in a second display mode 66 having a display range smaller than that of the first display mode 61. The second receipt 65 is a receipt having a receipt length shorter than that of the first receipt 60. The second display mode 66 displays transaction information in a display mode having a display range smaller than that of the first display mode 61 in order to shorten the receipt length.

The second display mode 66 includes a product display part 67, a subtotal display part 68, and an accounting result display part 69.
The product display unit 67 displays the purchased product information in a display range smaller than the product display unit 62 of the first display mode 61. The product display unit 67, for example, reduces the display range by compressing the characters of the purchased product information of products for which no privilege has been granted in the vertical direction (roll paper ticketing direction). In addition, the product display unit 67 reduces the display range by narrowing the interval between rows of purchased product information of products for which no privilege is given. By displaying the purchased product information in such a display mode, the product display unit 67 can make the display range smaller than the product display unit 62 of the first display mode 61. Also, since the horizontal direction is not related to the efficient use of roll paper, it is possible to achieve both efficient use and visibility of the roll paper by compressing the characters in the vertical direction while maintaining the horizontal size of the characters. . In addition, the receipt length is shortened while ensuring the convenience of the user by not reducing the display range of the purchased product information of the product to which the privilege considered to be highly confirmed by the user is given. it can.

  The subtotal display unit 68 displays the subtotal information in a display range smaller than the subtotal display unit 63 of the first display mode 61. The subtotal display unit 68 reduces the display range by, for example, compressing the characters of the subtotal information in the vertical direction. In addition, the product display unit 67 reduces the display range by narrowing the space between the upper and lower lines of the subtotal information. By displaying the subtotal information in such a display mode, the subtotal display unit 68 can make the display range smaller than the subtotal display unit 63 of the first display mode.

  The accounting result display unit 69 displays the accounting result information in the same display range as the accounting result display unit 69 of the first display mode 61. In this way, the display length of the entire second display mode 66 is ensured while ensuring the convenience of the user by displaying in the display range of the accounting result information that the user is likely to confirm with a receipt at a later date. Can be shortened.

  The second display mode 66 is an example and is not limited to this. For example, the 2nd display mode 66 may make the display range of the accounting result information displayed on the accounting result display part 69 small, and should just display transaction information in a display range smaller than a 1st display mode.

Next, a table held by the roll stock information storage unit 43 will be described with reference to FIG. FIG. 8 is a diagram illustrating a data structure example of an inventory information table in the second embodiment.
The stock information table 70 is stored in the roll stock information storage unit 43. The stock information table 70 includes items related to stock of roll paper. The inventory information table 70 is used when the evaluation unit 41 evaluates an out-of-stock risk. The stock information table 70 is updated when the stock of roll paper or the delivery date of the roll paper changes. The inventory information table 70 includes items of inventory quantity and delivery date. The information arranged in the horizontal direction of each item is associated with each other to constitute the stock information of the roll paper.

  The stock amount is the stock amount of roll paper. In the item of inventory quantity, for example, the inventory quantity “80 rolls” of roll paper held as inventory is set. The inventory quantity item is updated based on the roll paper delivery notice. The item of inventory quantity is updated when the replacement detection unit 53 detects replacement of roll paper.

  The delivery date is the delivery date of the roll paper. In the item of delivery date, for example, the delivery date “10 days later” of the roll paper is set. The delivery date item is updated based on the roll paper order notification. Also, the delivery date item is updated when the date changes.

Next, a table held by the evaluation information storage unit 42 will be described with reference to FIG. FIG. 9 is a diagram illustrating a data structure example of the evaluation information table in the second embodiment.
The evaluation information table 75 is stored in the evaluation information storage unit 42. In the evaluation information table 75, items relating to threshold values used for evaluation of out-of-stock risks are provided. The evaluation information table 75 is used when the evaluation unit 41 evaluates the out-of-stock risk. The evaluation information table 75 is configured to include items of a threshold stock quantity and a threshold delivery date. Information arranged in the horizontal direction of each item is associated with each other to constitute evaluation information.

  The threshold stock amount is a threshold value of the roll paper stock amount. For example, the threshold value “20 rolls” of the inventory amount is set in the threshold inventory amount item. The threshold stock quantity is used when the evaluation unit 41 evaluates the out-of-stock risk. In the out-of-stock risk evaluation, the evaluation unit 41 compares the threshold stock amount with the roll paper stock amount. The evaluation of the out-of-stock risk of the evaluation unit 41 is “high risk” when the roll paper stock quantity is less than the threshold stock quantity, and “low risk” when the roll paper stock quantity is greater than or equal to the threshold stock quantity. It is.

  The threshold delivery date is a threshold value for the delivery date of the roll paper. In the threshold delivery date item, for example, a delivery date threshold “after 3 days” is set. The threshold delivery date is used when the evaluation unit 41 determines whether to evaluate the out-of-stock risk. When deciding whether or not to evaluate the out-of-stock risk, the evaluation unit 41 compares the threshold delivery date with the roll paper delivery date. The evaluation unit 41 evaluates the out-of-stock risk when the delivery date of the roll paper is greater than or equal to the threshold delivery date, and does not evaluate the out-of-stock risk when the delivery date of the roll paper is less than the threshold delivery date.

Next, a table held by the control state storage unit 45 will be described with reference to FIG. FIG. 10 is a diagram illustrating a data structure example of a control state table in the second embodiment.
The control state table 80 is stored in the control state storage unit 45. The control state table 80 is provided with an item of the control state of the ticket issuing of the receipt performed by the ticket issuing control unit 52 to the ticket issuing unit 51. The control state table 80 is updated based on an instruction given by the instruction unit 44. The control state table 80 includes a control state item.

  The control state is a control state of the ticket issuing of the receipt performed by the ticket issuing control unit 52 to the ticket issuing unit 51. The control state includes a state in which the control of issuing the first receipt 60 is performed and the second receipt 65. There is a state in which ticketing control is performed. The control state item is updated based on the instruction given by the instruction unit 44. The control state item is updated when the instruction unit 44 instructs the ticketing control unit 52 to switch the ticketing from the second receipt 65 to the first receipt 60. The control state item is updated when the instructing unit 44 instructs the ticketing control unit 52 to switch the ticketing from the first receipt 60 to the second receipt 65. In the control status item, one of “first receipt” and “second receipt” is set. When the “first receipt” is set, the ticket issuing control unit 52 performs control to issue the first receipt 60 from the ticket issuing unit 51. When the “second receipt” is set, the ticket issuing control unit 52 performs control to issue the second receipt 65 from the ticket issuing unit 51.

Next, the exchange detection process will be described with reference to FIG. FIG. 11 is a flowchart of the exchange detection process in the second embodiment.
The exchange detection process is a process performed by the exchange detection unit 53 of the POS terminal 12. The replacement detection process is executed when the replacement detection unit 53 detects that the roll paper attached to the printer 29 has been replaced. In the replacement detection process, the replacement detection unit 53 detects the replacement of the roll paper and notifies the POS server 13 of the replacement of the roll paper.

  [Step S1] The replacement detection unit 53 determines whether or not replacement of roll paper is detected. The replacement detection unit 53 proceeds to step S1 when the replacement of the roll paper is not detected, and proceeds to step S2 when the replacement of the roll paper is detected.

  [Step S2] The replacement detection unit 53 updates the stock amount of roll paper stored in the roll stock information storage unit 43, and then ends the replacement detection process. According to such replacement detection processing, when the printer 29 performs roll paper replacement, the replacement detection unit 53 detects roll paper replacement and updates the roll paper stock amount. As described above, when the replacement detection unit 53 detects the replacement of the roll paper and updates the stock amount of the roll paper, the POS server 13 can sequentially manage the stock amount of the roll paper.

Next, the risk evaluation process will be described with reference to FIG. FIG. 12 is a flowchart of the risk evaluation process in the second embodiment.
The risk evaluation process is a process performed by the evaluation unit 41 of the POS server 13. The evaluation unit 41 performs risk evaluation processing when the stock amount of roll paper is updated. The evaluation unit 41 is not limited to performing the risk evaluation process when the stock amount of roll paper is updated. For example, the evaluation unit 41 may perform risk evaluation processing at the timing when the POS server 13 is activated every morning. The evaluation unit 41 evaluates the out-of-stock risk based on the roll paper stock information managed by the roll stock information storage unit 43 and the evaluation information.

[Step S11] The evaluation unit 41 accesses the roll stock information storage unit 43, and acquires the delivery date of the roll paper and the stock amount of the roll paper.
[Step S12] The evaluation unit 41 accesses the evaluation information storage unit 42, and acquires a threshold delivery date and a threshold inventory.

[Step S13] The evaluation unit 41 compares the acquired delivery date of the roll paper with a threshold delivery date.
[Step S14] The evaluation unit 41 determines whether or not the delivery date of the roll paper is equal to or greater than the threshold delivery date. The evaluation unit 41 proceeds to step S15 when it is determined that the delivery date of the roll paper is equal to or greater than the threshold delivery date, and ends the risk evaluation process when it is determined that the delivery date of the roll paper is less than the threshold delivery date.

  As described above, when the roll paper delivery date is less than the threshold delivery date, the evaluation unit 41 does not perform the risk evaluation process even when the roll paper stock amount is updated. And since the evaluation part 41 does not evaluate, the instruction | indication part 44 does not perform a new control instruction | indication to the ticket issuing control part 52. FIG. That is, when the delivery date is less than the threshold delivery date, the ticket issuing control unit 52 continues to control the ticket issuing unit 51 with the instruction content received from the instruction unit 44 when the delivery date is equal to or greater than the threshold delivery date.

[Step S15] The evaluation unit 41 compares the stock amount of roll paper with the threshold stock amount.
[Step S16] The evaluation unit 41 determines whether or not the stock amount of roll paper is equal to or greater than a threshold stock amount. The evaluation unit 41 proceeds to step S18 when determining that the stock amount of roll paper is greater than or equal to the threshold stock amount, and proceeds to step S17 when determining that the stock amount of roll paper is less than the threshold stock amount.

[Step S17] The evaluation unit 41 evaluates the out-of-stock risk as “high risk”. And the evaluation part 41 sends an evaluation result to the instruction | indication part 44, and complete | finishes a risk evaluation process.
[Step S18] The evaluation unit 41 evaluates the out-of-stock risk as “low risk”. And the evaluation part 41 sends an evaluation result to the instruction | indication part 44, and complete | finishes a risk evaluation process.

  As described above, when the roll paper delivery date is less than the threshold delivery date, the evaluation unit 41 does not perform risk assessment because the out-of-stock risk cannot be appropriately evaluated, and the roll paper delivery date is greater than or equal to the threshold delivery date. Evaluate. The evaluation unit 41 evaluates “low risk” when the roll paper stock amount is equal to or larger than the threshold stock amount, and evaluates “high risk” when the roll paper stock amount is less than the threshold stock amount. To do.

Next, the instruction process will be described with reference to FIG. FIG. 13 is a flowchart of instruction processing in the second embodiment.
The instruction process is a process performed by the instruction unit 44 of the POS server 13. The instruction unit 44 performs an instruction process upon receiving the evaluation result of the risk evaluation process. Also, the instruction unit 44 performs an instruction process upon receiving a roll paper delivery notice. The instruction unit 44 instructs the ticketing control unit 52 of the POS terminal 12 to switch the receipt issued by the ticketing unit 51.

  [Step S21] The instruction unit 44 determines whether or not a roll paper delivery notice has been received. The instruction unit 44 proceeds to step S22 when it is determined that a roll paper delivery notice has been received, and proceeds to step S26 when it is determined that a roll paper delivery notice has not been received.

[Step S22] The instruction unit 44 accesses the control state storage unit 45 and acquires the control state.
[Step S <b> 23] The instruction unit 44 determines whether or not the acquired control state is the second receipt 65. The instruction unit 44 proceeds to step S24 when it is determined that the acquired control state is the second receipt 65, and ends the instruction process when it is determined that the acquired control state is the first receipt 60.

[Step S24] The instructing unit 44 instructs the ticketing control unit 52 to switch from the second receipt 65 to the first receipt 60.
[Step S25] The instruction unit 44 updates the control state to the first receipt 60, and ends the instruction process.

  [Step S <b> 26] The instruction unit 44 determines whether or not the evaluation result of the out-of-stock risk has been received from the evaluation unit 41. The instruction unit 44 proceeds to step S27 when it is determined that the evaluation result of the out-of-stock risk is received from the evaluation unit 41, and ends the instruction process when it is determined that the evaluation result is not received from the evaluation unit 41.

  [Step S27] The instruction unit 44 determines whether or not the received out-of-stock risk evaluation result is “high risk”. The instruction unit 44 proceeds to step S28 when it is determined that the received out-of-stock risk evaluation result is “high risk”, and when it is determined that the received out-of-stock risk evaluation result is not “high risk”. Proceed to S22.

[Step S28] The instruction unit 44 accesses the control state storage unit 45 and acquires the control state.
[Step S29] The instruction unit 44 determines whether or not the acquired control state is the first receipt 60. The instruction unit 44 proceeds to step S30 when it is determined that the acquired control state is the first receipt 60, and ends the instruction process when it is determined that the acquired control state is the second receipt 65.

[Step S30] The instruction unit 44 instructs the ticketing control unit 52 to switch from the first receipt 60 to the second receipt 65.
[Step S31] The instruction unit 44 updates the control state to the second receipt 65, and ends the instruction process.

  In this way, the instruction unit 44 issues a switching instruction from the second receipt 65 to the first receipt 60 upon receiving the roll paper delivery notification. In addition, the instruction unit 44 issues a switching instruction from the first receipt 60 to the second receipt 65 based on the evaluation result of the out-of-stock risk. In other words, the instruction unit 44 causes the ticket issuing control unit 52 to issue the second receipt 65 when the possibility that the stock will run out becomes high (when the risk is high). Further, when the possibility of out of stock decreases (when roll paper is delivered and the stock quantity increases), the ticket issuing control unit 52 issues the first receipt 60.

  The above is the POS system 11 of the second embodiment. The POS system 11 evaluates the risk of out-of-stock, and issues a first receipt 60 that displays the transaction information in the first display mode 61 considering the convenience of the user when out-of-stock is unlikely to occur (normal time). To do. Then, the POS system 11 evaluates the risk of out of stock, and when the stock out is likely to occur, the transaction information is displayed in the second display mode 61 having a display range smaller than the first display mode 61, and the first receipt is displayed. A second receipt 65 having a receipt length shorter than 60 is issued.

  As described above, the POS system 11 can evaluate the out-of-stock risk, and can prevent the roll paper from being out of stock by switching the receipt to be issued from the first receipt 60 to the second receipt 65 when the out-of-stock risk increases.

  Further, since the POS server 13 instructs the POS terminal 12 to switch to the receipt that efficiently uses the roll paper based on the out-of-stock risk, the roll paper of the roll paper is considered in consideration of an unexpected increase in the use amount of the roll paper. It is no longer necessary to have excessive stock in advance. Therefore, the POS system 11 can suppress stock of roll paper.

  Although the threshold stock quantity has been described as a fixed value, the threshold stock quantity may be changed depending on the delivery date. For example, when the period until the delivery date is long, the threshold stock quantity is set large, and when the period until the delivery date is short, the threshold stock quantity is set small. Further, although the out-of-stock risk is not evaluated when the delivery date is less than the predetermined number of days, the out-of-stock risk may be evaluated regardless of the period until the delivery date.

[Third embodiment]
Next, a third embodiment, which is a modification of the second embodiment, will be described. About the point similar to 2nd embodiment, the same number is attached and description is abbreviate | omitted suitably. In the third embodiment, the POS server 13 stores the roll paper usage history of the POS terminal 12 and determines the POS terminal 12 to give an instruction according to the usage history.

  Specifically, the POS server 13 stores the usage history to calculate the roll paper usage for each POS terminal. The POS server 13 instructs the POS terminal 12 whose roll paper usage is equal to or greater than a predetermined amount to switch the receipt to be issued. That is, the POS terminal 12 that uses a large amount of roll paper issues the second receipt 65 when the stock is likely to run out. The POS terminal 12 that uses a small amount of roll paper continues to issue the first receipt 60 even if the stock is likely to run out of stock.

  Here, functions provided in the POS system 11 will be described. FIG. 14 is a functional block diagram of the POS system in the third embodiment. Since the POS terminal 12 can be realized by the same function as in the second embodiment, description thereof is omitted.

  The POS server 13 includes an evaluation unit 41, an evaluation information storage unit 42, a roll inventory information storage unit 43, an instruction unit 44, a control state storage unit 45, a communication unit 46, and a usage history storage unit 100. The third embodiment differs from the second embodiment in that the POS server 13 includes a usage history storage unit 100.

  The usage history storage unit 100 stores roll paper usage history information (use history information) for each POS terminal. The usage history storage unit 100 stores, for example, a history of the amount of roll paper used by the POS terminal 12 during a predetermined period. The amount of roll paper used is the number of times the roll paper has been replaced. The POS server 13 can acquire the amount of roll paper used by counting the number of times the replacement detection unit 53 has detected replacement during a predetermined period. The usage history storage unit 100 is used when the instructing unit 44 determines the POS terminal 12 to instruct receipt switching. Specifically, the instruction unit 44 uses the usage history storage unit 100 to identify the POS terminal 12 whose roll paper usage is greater than or equal to a predetermined amount, and issues a receipt switching instruction to the identified POS terminal 12. That is, the POS terminal 12 in which the amount of roll paper used is less than the predetermined amount is instructed to switch from the first receipt 60 to the second receipt 65 even when the out-of-stock risk evaluation result is “high risk”. Not performed. In this way, the POS terminal 12 with a small amount of roll paper used is not instructed to switch to the POS terminal 12 with a small amount of roll paper used, even if the POS terminal 12 with a small amount of roll paper used is switched to the second receipt 65. This is because it does not contribute much to the decrease in the amount of use.

  As described above, the instruction unit 44 issues a switching instruction to the POS terminal 12 in which the amount of roll paper used is a predetermined amount or more, so that the roll paper can be efficiently used in the entire POS system. Further, since the POS terminal 12 in which the amount of roll paper used is less than the predetermined amount continues to issue the first receipt 60, the convenience of the user can be ensured as compared with the case where the switching instruction is given to all the POS terminals. . The usage history information held by the usage history storage unit 100 will be described later in detail with reference to FIG.

  In the third embodiment, since the instruction unit 44 issues a receipt switching instruction according to the amount of roll paper used, the control state of the POS terminal 12 may differ depending on the amount of roll paper used. Therefore, the control state storage unit 45 stores the control state of the POS terminal 12 in which the amount of roll paper used is less than the predetermined amount and the control state of the POS terminal 12 in which the amount of roll paper used is equal to or greater than the predetermined amount. The control state information stored in the control state storage unit 45 is used when the instruction unit 44 determines the POS terminal 12 that issues a receipt switching instruction. The control state information held by the control state storage unit 45 will be described in detail later with reference to FIG.

Next, the table held by the usage history storage unit 100 will be described with reference to FIG. FIG. 15 is a diagram illustrating an example of a data structure of a usage history table in the third embodiment.
The usage history table 105 is stored in the usage history storage unit 100. In the usage history table 105, items relating to the usage history of the roll paper are provided. The usage history table 105 is used when the instructing unit 44 determines the POS terminal 12 to instruct. The usage history table 105 has a No. And sales section classification, usage history, average usage for each terminal, and average usage for each sales section. The information arranged in the horizontal direction of each item is associated with each other to constitute the usage history information of the POS terminal 12.

  No. Is an identification number for uniquely identifying the POS terminal 12 set for each POS terminal. No. In the item, for example, the identification number “1” of the POS terminal 12 is set. The sales floor section is a section of the sales floor where the POS terminal 12 is installed. In the item of the sales floor section, for example, the sales floor section “food” in which the POS terminal 12 is installed is set.

  The usage history is a usage history of roll paper used by the POS terminal 12. In the usage history item, the amount of roll paper used by the POS terminal 12 is set on a monthly basis. In the usage history item, for example, the roll paper usage amount “13 rolls” of January 2012 of the POS terminal 12 is set.

  The average usage amount for each terminal is the average usage amount of roll paper used by the POS terminal 12. The average usage amount for each terminal is an example of information used when the instruction unit 44 determines the POS terminal 12 to instruct. The instructing unit 44 can change the instruction in units of terminals by determining the POS terminal 12 that issues a receipt switching instruction using the average usage amount for each terminal. As described above, the instruction unit 44 changes the instruction in units of terminals, so that it is possible to give priority to the convenience of the user in the POS terminal 12 that does not contribute to the prevention of the out of stock while preventing the POS system as a whole. The average usage amount for each terminal is, for example, the usage amount obtained by averaging the usage history of the POS terminal 12 for 12 months. In the item of average usage amount for each terminal, for example, the usage amount “14 rolls” of roll paper used on average by the POS terminal 12 is set.

  The average usage for each sales floor section is an average usage of the roll paper used by the POS terminal 12 for each sales floor section. The sales floor division is an example of a group to which the POS terminal belongs. The average usage amount for each sales floor division is an example of information used when the instruction unit 44 determines the POS terminal 12 to instruct. The instruction unit 44 can change the instruction in units of sales floors by determining the POS terminal 12 that issues a receipt switching instruction using the average usage amount for each sales floor. As described above, the instruction unit 44 changes the instruction in units of sales floors, so that the convenience of the user can be prioritized in a sales floor that does not contribute to the prevention of out of stock while preventing the POS system as a whole. Therefore, despite the accounting at the POS terminal 12 at the same sales floor, there is no distrust in the user due to different receipts. In the item of average usage for each sales floor section, for example, a usage “16 roll” is set by averaging the average usage for each POS terminal installed in the same sales floor.

Next, a table held by the control state storage unit 45 will be described with reference to FIG. FIG. 16 is a diagram illustrating a data structure example of a control state table in the third embodiment.
The control state table 110 is stored in the control state storage unit 45. The control state table 110 is used when the instruction unit 44 determines the POS terminal 12 to instruct. The control state table 110 includes a control No. And threshold usage and control status items. Information arranged in the horizontal direction of each item is associated with each other to form control state information. The control state table 110 according to the third embodiment includes a control No. And the threshold usage amount item are different from the second embodiment.

  Control No. Is identification information that can uniquely identify the control state information. The control status information includes control status information of the POS terminal 12 that is less than a predetermined amount of roll paper used and control status information of the POS terminal 12 that is greater than or equal to the used amount of roll paper. Control No. The control status information whose “1” is “1” is the control status information of the POS terminal 12 whose roll paper usage is less than the predetermined amount. Control No. The control status information with “2” is the control status information of the POS terminal 12 that is equal to or greater than the predetermined amount of roll paper used. Control No. For example, the control No. “1” is set.

  The threshold usage amount is a threshold for the usage amount of roll paper. The threshold usage amount corresponds to the corresponding control No. This is used to identify the POS terminal 12 that is controlled. In the threshold usage amount item, for example, a usage amount threshold “0 to less than 2 rolls” is set.

  In the control state item, the control state of the ticket issuing of the receipt performed by the ticket issuing control unit 52 to the ticket issuing unit 51 is set. For example, the control state “first receipt” is set in the item of the control state. Control No. In the control state item specified by “1”, the control state of the POS terminal 12 that uses a small amount of roll paper is set. Control No. In the control state item specified by “2”, the control state of the POS terminal 12 that uses a large amount of roll paper is set.

  Next, the instruction process will be described with reference to FIGS. 17 and 18 are flowcharts of instruction processing in the third embodiment. In the third embodiment, the instruction unit 44 is different from the instruction processing of the second embodiment in that an instruction is given to the POS terminal 12 in which the amount of roll paper used is a predetermined amount or more.

  [Step S51] The instruction unit 44 determines whether or not a roll paper delivery notice has been received. The instruction unit 44 proceeds to step S52 when it is determined that a roll paper delivery notice has been received, and proceeds to step S59 when it is determined that a roll paper delivery notice has not been received.

[Step S52] The instructing unit 44 accesses the control state storage unit 45 and sets the control No. And threshold usage and control status are acquired.
[Step S53] The instruction unit 44 sets the control No. Select one.

  [Step S54] The instruction unit 44 selects the selected control No. Whether the control state is the second receipt 65 or not is determined. The instruction unit 44 selects the selected control No. If it is determined that the control state is the second receipt 65, the process proceeds to step S55, and the selected control No. When it is determined that the control state is the first receipt 60, the process proceeds to step S58.

  [Step S55] The instructing unit 44 accesses the usage history storage unit 100 and acquires an average usage amount (an average usage amount for each terminal or an average usage amount for each sales division). The instruction unit 44 uses the acquired average usage amount and the selected control No. POS terminals 12 satisfying the average usage amount of roll paper satisfying the threshold usage amount are identified. The instruction unit 44 determines the identified POS terminal 12 as an instruction target.

[Step S56] The instruction unit 44 instructs the ticketing control unit 52 of the POS terminal 12 to be instructed to switch from the second receipt 65 to the first receipt 60.
[Step S57] The instruction unit 44 selects the selected control No. Update the control state.

  [Step S58] The instruction unit 44 sets all control Nos. It is determined whether or not is selected. The instruction unit 44 displays all control numbers. When it is determined that the control process is selected, the instruction process is terminated, and all control Nos. If it is determined that no is selected, the process proceeds to step S53.

  [Step S <b> 59] The instruction unit 44 determines whether an evaluation result is received from the evaluation unit 41. The instruction unit 44 proceeds to step S60 when it is determined that the evaluation result is received from the evaluation unit 41, and ends the instruction process when it is determined that the evaluation result is not received from the evaluation unit 41.

  [Step S60] The instruction unit 44 determines whether or not the received evaluation result is “high risk”. The instruction unit 44 proceeds to step S61 when it is determined that the received evaluation result is “high risk”, and proceeds to step S52 when it is determined that the received evaluation result is not “high risk”.

[Step S61] The instructing unit 44 accesses the control state storage unit 45 and sets the control No. And threshold usage and control status are acquired.
[Step S62] The instruction unit 44 sets the control No. Select one.

  [Step S63] The instruction unit 44 selects the selected control No. It is determined whether or not “2” is “2”. The instruction unit 44 selects the selected control No. Is determined to be “2”, the process proceeds to step S64, and the selected control No. When it is determined that is “1”, the process proceeds to step S68.

  [Step S64] The instruction unit 44 sets the selected control No. It is determined whether or not the control state is the first receipt 60. The instruction unit 44 selects the selected control No. If the control state is determined to be the first receipt 60, the process proceeds to step S65, and the selected control No. If it is determined that the control state is not the first receipt 60, the process proceeds to step S68.

  [Step S65] The instruction unit 44 accesses the usage history storage unit 100 and obtains an average usage amount. Instruction unit 44, the acquired average usage amount and the selected control No. POS terminals 12 that satisfy the threshold usage amount are identified by comparing the threshold usage amounts. The instruction unit 44 determines the specified POS terminal 12 as an instruction target.

[Step S66] The instruction unit 44 instructs the ticketing control unit 52 of the POS terminal 12 to be instructed to switch from the first receipt 60 to the second receipt 65.
[Step S67] The instruction unit 44 sets the selected control No. Update the control state.

[Fourth embodiment]
Next, the fourth embodiment, which is a modification of the second embodiment, will be described. About the point similar to 2nd embodiment, the same number is attached and description is abbreviate | omitted suitably.

  In the second embodiment, the evaluation unit 41 uses the stock amount of roll paper for evaluating the out-of-stock risk. In the fourth embodiment, the evaluation unit 41 calculates the total amount of the remaining amount of roll paper attached to the POS terminal 12 and the inventory amount of roll paper for evaluation of out-of-stock risk, and uses the calculated total amount for inventory. Assess cut risk. The out-of-stock risk evaluation using the calculated total amount can be realized by replacing “stock amount of roll paper” with “total amount” in the risk evaluation process of the second embodiment.

Here, functions provided in the POS system 11 will be described. FIG. 19 is a functional block diagram of the POS system in the fourth embodiment.
The POS terminal 12 includes a ticket issuing unit 51, a ticket issuing control unit 52, an exchange detection unit 53, a communication unit 54, and a roll information detection unit 210. The fourth embodiment differs from the second embodiment in that the POS terminal 12 includes a roll information detection unit 210.

  The roll information detection unit 210 detects roll information used to calculate the remaining amount of roll paper attached to the POS terminal 12. The roll information is information that can specify the remaining amount of roll paper. The roll information is, for example, the weight of the roll paper or the thickness of the roll paper. Hereinafter, roll information is described as the weight of roll paper. The roll information detection unit 210 detects the weight of the roll paper of the POS terminal 12 every predetermined time. For example, the roll information detection unit 210 detects the weight of the roll paper when the store is closed. The roll information detection unit 210 notifies the detected roll information to the remaining amount calculation unit 200. Note that the POS terminal 12 may detect the remaining amount of roll paper.

  The POS server 13 includes an evaluation unit 41, an evaluation information storage unit 42, a roll stock information storage unit 43, an instruction unit 44, a control state storage unit 45, a communication unit 46, a remaining amount calculation unit 200, and a remaining amount calculation information storage unit 205. It is comprised including. The fourth embodiment differs from the second embodiment in that the POS server 13 includes a remaining amount calculation unit 200 and a remaining amount calculation information storage unit 205. Note that the POS server 13 may include the function (use history storage unit 100) of the third embodiment.

  The remaining amount calculation information storage unit 205 stores information (remaining amount calculation information) used for calculating the remaining amount of roll paper. The remaining amount calculation information storage unit 205 stores the weight of the roll paper and the remaining amount of the roll paper in association with each other. The remaining amount calculation information storage unit 205 is used when the remaining amount calculation unit 200 calculates the remaining amount of roll paper. The remaining amount calculation information storage unit 205 will be described in detail later with reference to FIG.

  The remaining amount calculation unit 200 calculates the total remaining amount of roll paper remaining in the POS terminal 12 constituting the POS system 11. The remaining amount calculation unit 200 receives the weight of the roll paper attached to the POS terminal 12 from the roll information detection unit 210 of the plurality of POS terminals 12. The remaining amount calculation unit 200 calculates the remaining amount of roll paper attached to the POS terminal 12 using the received roll weight and the remaining amount calculation information storage unit 205. Then, the remaining amount calculation unit 200 calculates the total remaining amount of roll paper remaining in the POS terminal 12 by summing the calculated remaining amount of roll paper remaining in each POS terminal 12. The remaining amount calculation unit 200 causes the roll stock information storage unit 43 to store the calculated total remaining amount of roll paper.

  In the second embodiment, the risk evaluation process is performed when the roll paper stock amount is updated. However, in the fourth embodiment, the total amount of the remaining roll paper amount and the roll paper stock amount is updated. Risk assessment processing is performed if

Next, a table held by the remaining amount calculation information storage unit 205 will be described with reference to FIG. FIG. 20 is a diagram illustrating a data structure example of a remaining amount calculation table in the fourth embodiment.
The remaining amount calculation table 220 is stored in the remaining amount calculation information storage unit 205. The remaining amount calculation table 220 includes an item relating to the remaining amount of roll paper. The remaining amount calculation table 220 includes items of roll weight and remaining roll amount. Information arranged in the horizontal direction of each item is associated with each other to form one remaining amount calculation information. The roll weight is the weight of the roll paper attached to the POS terminal 12. In the item of roll weight, for example, the weight “149 g to 130 g” of the roll paper is set as the threshold value.

  The remaining roll amount is the remaining amount of roll paper attached to the POS terminal 12. In the roll remaining amount item, a remaining amount of roll paper corresponding to the weight of the roll paper is set. In the roll remaining amount item, for example, the remaining amount of roll paper “0.8 rolls” when the weight of roll paper is “149 g to 130 g” is set.

By using such a remaining amount calculation table 220, the remaining amount calculation unit 200 can calculate the remaining amount of roll paper from the weight of the roll paper detected by the roll information detection unit 210.
Next, a table held by the roll stock information storage unit 43 will be described with reference to FIG. FIG. 21 is a diagram illustrating a data structure example of an inventory information table in the fourth embodiment.

  The stock information table 225 is stored in the roll stock information storage unit 43. The inventory information table 225 includes items of inventory quantity, total remaining quantity, total quantity, and delivery date. The information arranged in the horizontal direction of the items is associated with each other to constitute inventory information. The inventory information table 225 of the fourth embodiment is different from the second embodiment in that it includes items of total remaining amount and total amount.

  The total remaining amount is a remaining amount obtained by summing up the roll paper remaining in each POS terminal 12. In the item of the total remaining amount, for example, the total remaining amount “4 rolls” of the roll paper remaining in the POS terminal 12 is set. The item of the total remaining amount is updated when the remaining amount calculation unit 200 calculates the total of the remaining amount of roll paper of the POS terminal 12.

  The total amount is the sum total of the stock amount and the total remaining amount. The total amount is used when the evaluation unit 41 evaluates the out-of-stock risk. In the total amount item, a total amount “84 rolls” obtained by adding up the stock amount “80 rolls” and the total remaining amount “4 rolls” is set.

  Next, roll information detection processing will be described. FIG. 22 is a flowchart of roll information detection processing in the fourth embodiment. The roll information detection process is a process performed by the roll information detection unit 210. The roll information detection unit 210 performs roll information detection processing at a predetermined timing (for example, when the store is closed or at a predetermined time interval). The roll information detection unit 210 detects the weight of the roll paper attached to the printer 29 and notifies the detected weight of the roll paper to the remaining amount calculation unit 200 of the POS server 13 via the communication units 54 and 46.

  [Step S101] The roll information detection unit 210 determines whether it is a detection timing for detecting the remaining amount of roll paper. The roll information detection unit 210 proceeds to step S102 when it is determined that it is the detection timing for detecting the remaining amount of roll paper, and proceeds to step S101 when it is determined that it is not the detection timing for detecting the remaining amount of roll paper. Wait until it is time.

[Step S102] The roll information detector 210 detects the weight of the roll paper attached to the printer 29 of the POS terminal 12.
[Step S103] The roll information detection unit 101 notifies the remaining amount calculation unit 200 of the detected roll paper weight via the communication units 54 and 46, and then ends the roll information detection process.

  Next, the remaining amount calculation process will be described. FIG. 23 is a flowchart of remaining amount calculation processing in the fourth embodiment. The remaining amount calculation process is a process performed by the remaining amount calculation unit 200. When the remaining amount calculation unit 200 receives roll information from the roll information detection unit 101, the remaining amount calculation unit 200 performs a remaining amount calculation process. The remaining amount calculation unit 200 calculates the remaining amount of roll paper remaining in each POS terminal 12 using the remaining amount calculation information storage unit 205 and the weight of the roll paper received from each POS terminal 12, and the POS terminal 12 The total remaining amount of the roll paper remaining on is calculated.

  [Step S <b> 111] The remaining amount calculation unit 200 determines whether the weight of the roll paper has been received from all the POS terminals 12 included in the POS system 11. When the remaining amount calculation unit 200 determines that the roll paper weight has been received from all the POS terminals 12, the process proceeds to step S112, and when the remaining amount calculation unit 200 determines that the roll paper weight has not been received from all the POS terminals 12. Proceed to step S111.

  Note that the present invention is not limited to determining whether or not the weight of the roll paper has been received from all the POS terminals 12 constituting the POS system 11. For example, it may be determined whether or not the weight of the roll paper has been received from all operating POS terminals 12.

[Step S112] The remaining amount calculation unit 200 selects one of the received roll paper weights.
[Step S113] The remaining amount calculation unit 200 compares the weight of the selected roll paper with the remaining amount calculation table 220, and calculates the remaining amount of the roll paper from the weight of the roll paper.

  [Step S114] The remaining amount calculation unit 200 determines whether or not the remaining amount of roll paper has been calculated from the weights of all the received roll papers. When it is determined that the remaining amount of roll paper has been calculated from the received weights of all roll papers, the remaining amount calculating unit 200 proceeds to step S115, and calculates the remaining amount of roll paper from the received weights of all roll papers. If it is determined that the calculation has not been completed, the process proceeds to step S112.

[Step S115] The remaining amount calculation unit 200 sums the calculated remaining amount of roll paper, and calculates the total remaining amount of roll paper remaining in the POS terminal 12.
[Step S116] After the remaining amount calculation unit 200 updates the total remaining amount, the remaining amount calculation process ends.

  The above is the POS system 11 of the fourth embodiment. According to such a POS system 11, the evaluation unit 41 evaluates the roll paper out-of-stock risk using the total amount of the roll paper stock and the remaining roll paper remaining in the POS terminal 12. In this way, the evaluation unit 41 uses the roll paper in use attached to the POS terminal 12 to evaluate the out-of-stock risk, and therefore more accurate out-of-stock compared to the case of evaluating using only the roll paper stock quantity. Can assess risk. The fourth embodiment can be combined with the third embodiment.
