Description

  The present invention relates to a relay device used in connection with a POS terminal and a POS peripheral device, a mounting board, a POS system including these, and a control method and program for the relay device.

  Conventionally, in a credit terminal connected to a host computer equipped with a customer data file via a communication line, the host computer is inquired about whether or not a credit transaction is possible, and if there is a transaction permission response from the host computer, a credit slip is printed. The thing is known (refer patent document 1). When the credit terminal detects an abnormality in communication with the host computer, the credit terminal determines whether or not a credit transaction can be performed in an offline state, and issues a credit slip when it determines that the transaction is successful. That is, the credit terminal can continue the credit processing by determining whether or not the credit transaction can be performed by itself, even when it becomes impossible to make an inquiry about whether or not the credit transaction is allowed to the host computer.

Japanese Patent No. 2509995

  It is conceivable to apply the configuration of the credit terminal described above to a POS terminal that is connected to a POS server. In such a case, when communication with the connected POS server becomes impossible, the POS terminal itself performs the accounting process. However, in this configuration, there is a problem that the accounting process cannot be executed if the POS terminal fails.

  In view of the above points, the present invention provides a relay device, a mounting board, a POS system including these, a relay device control method, and a program capable of executing accounting processing even if a POS terminal fails. Is an issue.

  A relay apparatus according to the present invention is a relay apparatus used by being connected to a POS terminal and a POS peripheral device, and includes a normal control unit that performs input / output control of the POS peripheral device based on a command from the POS terminal, and a POS terminal Normal control based on detection of a proxy control unit that performs input / output control of a POS peripheral device as a proxy for the POS terminal, a failure detection unit that detects a failure of the POS terminal, and a detection of the failure detection unit without receiving a command from the POS terminal And a control switching unit for switching from the input / output control of the unit to the input / output control of the proxy control unit.

  The relay device control method of the present invention is a relay device control method used by being connected to a POS terminal and a POS peripheral device. The relay device detects a failure of the POS terminal, and a failure detection step. Based on the detection of a failure in the POS terminal, the POS peripheral device input / output control is performed on behalf of the POS terminal without receiving the command from the POS terminal, from the normal control that performs the input / output control of the POS peripheral device by the command from the POS terminal. And a control switching step for switching to the proxy control to be performed.

  According to these configurations, since the relay device controls the POS peripheral device as a proxy for the POS terminal, the accounting process can be executed when the POS terminal fails. Further, since the control is switched based on the detection of the failure of the POS terminal by the failure detection unit, for example, in the store, the trouble of the store clerk such as the control switching operation is eliminated and the customer is not caused to wait, and the failure of the POS terminal Even at times, the processing efficiency in the accounting process can be maintained.

  In this case, the POS peripheral device includes a code input device that can input a product code, a numeric keypad input device that can input a product price, and a printing device that prints a receipt, and the POS terminal includes a POS that includes a product database. Connected to the server, obtains product information corresponding to the product code from the POS server, generates receipt print data, and the normal control unit outputs at least the product code obtained from the code input device to the POS terminal; The receipt control data is acquired from the POS terminal, and the receipt print data is output to the printing apparatus. The proxy control unit at least acquires the product code and the product price acquired from the code input device and the numeric keypad input device. To generate receipt print data and output the receipt print data to the printing device. It is preferable to perform the control.

  According to this configuration, when the POS terminal fails, the relay device generates receipt print data based on the product code and the product price by the proxy control unit without acquiring the product information from the POS server, and prints the receipt. be able to.

  Further, the numeric keypad input device is a touch panel, the normal control unit displays a part of the receipt print data or product information acquired from the POS terminal on the touch panel, and the proxy control unit functions as a numeric keypad input device on the touch panel. It is preferable to display the product code and the product price as well as displaying the numeric keypad area.

  According to this configuration, at the time of input / output control of the proxy control unit, the numeric key area is displayed on the touch panel, so that the user can input the product price, the deposit price, the change price, etc. corresponding to the product code. As described above, since the information displayed on the touch panel is different and the input method is different between the input / output control of the normal control unit and the input / output control of the proxy control unit, the failure of the POS terminal can be notified to the user.

  In addition to the detection by the failure detection unit, the control switching unit preferably switches the input / output control of the normal control unit and the input / output control of the proxy control unit based on a user operation.

  According to this configuration, in addition to the failure of the POS terminal, even when the connection between the POS server and the POS terminal is disconnected, the accounting process can be executed in the relay device by the user switching operation.

  In addition, when the control switching unit is switched from the input / output control of the normal control unit to the input / output control of the proxy control unit, the proxy control unit transmits the proxy server from the application server connected to the relay device as a proxy for the POS terminal. It is preferable to obtain a proxy control program for performing input / output control of the POS peripheral device.

  According to this configuration, the proxy control unit can always obtain the latest version of the proxy control program.

  Alternatively, when the control switching unit switches from the input / output control of the normal control unit to the input / output control of the proxy control unit, the proxy control unit acts as a proxy for performing the input / output control of the POS peripheral device as a proxy of the POS terminal. It is preferable to access an application server that can operate the control program and perform control according to a proxy control program that operates on the application server.

  According to this configuration, since it is not necessary to store the proxy control program in the relay device, the configuration for that can be omitted.

  Moreover, it is preferable to further include a history storage unit that stores a history of input / output control controlled by the proxy control unit.

  According to this configuration, since the input history during execution of proxy control of the relay device is stored, it can be reflected later on the POS terminal (or POS server connected to the POS terminal).

  In this case, the input / output control history includes an input history made up of product codes. When the control switching unit switches from the input / output control of the proxy control unit to the input / output control of the normal control unit, the history storage unit It is preferable to further include a recovery processing unit that transmits the input history stored in the POS terminal.

  According to this configuration, since the product code input during the proxy control of the relay device is transmitted to the POS terminal by the recovery processing unit, the POS terminal can transmit the acquired product code to the POS server. In other words, without using a special recovery program, it is possible to reflect the history of proxy control execution of the relay device in the sales information managed by the POS server by a normal processing method.

  Alternatively, the input / output control history includes accounting processing information including receipt print data generated by the proxy control unit, and the proxy control program is a transmission program for the POS terminal to transmit accounting processing information to the POS server. In addition, when the control switching unit switches from the input / output control of the proxy control unit to the input / output control of the normal control unit, the accounting processing information stored in the history storage unit and the transmission program are transmitted to the POS terminal. It is preferable to further include a recovery processing unit.

  According to this configuration, the transaction processing information including the receipt print data generated during the proxy control of the relay device can be transmitted to the POS terminal by the recovery processing unit. Further, since the recovery processing unit transmits the transmission program at the same time, the POS terminal can transmit the accounting processing information acquired according to the transmission program to the POS server. As a result, it is possible to reflect the history of proxy control execution of the relay device in the sales information managed by the POS server. Furthermore, if the receipt print data includes the date and time when the accounting process was performed, the deposit amount, the change amount, etc., detailed accounting process information can be transmitted to the POS server, and the relay device proxy control is being executed. Information loss can be prevented.

  The mounting board of the present invention functions as the relay device described above, and is used by being mounted on a POS peripheral device.

  According to this configuration, space saving around the POS terminal and the POS peripheral device can be realized.

  A POS system according to the present invention includes the relay device, a POS terminal, and a POS peripheral device.

  According to this configuration, it is possible to provide a POS system in which a relay device executes accounting processing as a proxy for a POS terminal when a POS terminal fails.

  A program according to the present invention causes a computer to execute each step in the above-described control method of the relay device.

  According to this configuration, it is possible to provide a program that allows the relay device to execute the accounting process as a proxy for the POS terminal when the POS terminal fails.

  Hereinafter, a relay device of the present invention and a POS system including the same will be described with reference to the accompanying drawings. In each embodiment shown below, the relay device of the present invention is illustrated as applied to a mounting board mounted on a receipt printer. The relay device of the present invention has a function of executing accounting processing as a proxy for the POS terminal when the POS terminal fails.

[First Embodiment]
FIG. 1 is a block diagram of a POS system SY1 according to the first embodiment. As shown in the figure, a POS system SY1 includes a POS server 1 having a product database DB, a POS terminal 2 for performing accounting processing, a handy scanner 3 and a keyboard 4 (code input device) for inputting product codes, and a touch panel. Touch panel device 5 (ten-key input device) that displays a screen, receipt printer 6 (printing device) that issues receipt 31, cash drawer 7 that stores cash, and mounting board 8 that is mounted on receipt printer 6 Become. Although FIG. 1 shows a case where there is one POS terminal 2, a configuration in which a plurality of POS terminals 2 are connected to the POS server 1 may be used.

  The POS server 1 and the POS terminal 2 are connected by a network NT such as an intranet or the Internet. On the other hand, the POS terminal 2 and the mounting board 8 mounted on the receipt printer 6 are connected via a dedicated cable. The mounting board 8 is connected to the handy scanner 3, the keyboard 4, and the touch panel device 5 through independent interfaces (for example, a USB (Universal Serial Bus) interface). The cash drawer 7 is connected to the receipt printer 6 (printer body). Further, the POS terminal 2 and the mounting board 8 may be connected wirelessly instead of wired connection.

  The “POS peripheral device” includes a handy scanner 3, a keyboard 4, a touch panel device 5, a receipt printer 6, and a cash drawer 7. In addition, the touch panel device 5 is for a store clerk who performs a transaction processing operation to confirm the transaction information, but may further include a customer display for the customer to confirm the transaction information as a display device.

  The POS server 1 is installed, for example, in a store backyard and has a product database DB. FIG. 2 is a conceptual diagram of the product database DB. As shown in the figure, the product database DB includes a product information table TB1 in which “product code”, “product name”, “product price”, and “manufacturer name” (hereinafter referred to as product information) are tabulated, And a sales information table TB2 in which “product code”, “inventory quantity”, and “sales record” are tabulated. The POS server 1 updates the information in the sales information table TB2 based on the product code acquired from the POS terminal 2.

  When the POS terminal 2 acquires the product code input by the handy scanner 3 and the keyboard 4 via the mounting board 8, the POS terminal 2 refers to the product information table TB1 of the POS server 1 and acquires product information corresponding to the product code. Then, accounting processing and receipt print data generation are performed. Specifically, in the accounting process, the total amount is calculated based on the product amount included in the product information, and the change amount is calculated based on the calculated total amount and the inputted “custody amount”. The receipt print data is composed of the acquired product information, transaction processing result (accounting information), receipt issuance information, and store information (see FIG. 3A). Then, a command is issued to the mounting board 8 to issue a receipt based on the generated receipt print data. Note that the POS terminal 2 issues a command to the mounting board 8 to display the normal transaction processing screen 36A (see FIG. 4A) on the touch panel device 5 during the transaction process.

  The receipt printer 6 includes a mounting board 8 that is detachably attached and a printer main body 9 that performs a printing function.

  The failure detection unit 21 detects a failure of the POS terminal 2. Specifically, the failure detection unit 21 periodically transmits an operation confirmation signal to the POS terminal 2 and receives a response signal from the POS terminal 2 within a predetermined time. Thus, it is recognized that the POS terminal 2 is operating normally. On the other hand, when an operation confirmation signal is transmitted to the POS terminal 2 and no response signal is received from the POS terminal 2 for a predetermined time or more, it is determined that the POS terminal 2 has failed (failure is detected). Further, when the POS terminal 2 is out of order, the recovery of the POS terminal 2 is detected by receiving a response signal to the operation confirmation signal from the POS terminal 2.

  When the failure detection unit 21 detects a failure of the POS terminal 2, the control switching unit 22 issues a switching command to switch the control of the mounted board 8 from the normal control unit 23 to the proxy control unit 24. On the other hand, when the failure detection unit 21 detects the restoration of the POS terminal 2, it issues a switching command to switch the control of the mounting board 8 from the proxy control unit 24 to the normal control unit 23. In addition, even when a control switching operation is performed by a switching operation unit 16 described later, a control switching command between the normal control unit 23 and the proxy control unit 24 is issued. The mounting board 8 is switched to a normal mode in which control is performed by the normal control unit 23 and a proxy mode in which control is performed by the proxy control unit 24 according to a switching command of the control switching unit 22.

  When the mounted board 8 is switched to the normal mode, the normal control unit 23 executes input / output control (hereinafter referred to as normal control) of the POS peripheral device. Specifically, control for outputting the normal transaction processing screen 36A to the touch panel device 5, control for outputting the product code acquired from the handy scanner 3 or the keyboard 4 to the POS terminal 2, and acquisition of receipt print data from the POS terminal 2. And control for outputting the receipt print data to the printer main body 9. That is, the normal control unit 23 executes input / output control of the POS peripheral device for the mounting board 8 to function as a relay device between the POS terminal 2 and the peripheral device.

  When the mounted board 8 is switched to the proxy mode, the proxy control unit 24 performs accounting processing on behalf of the POS terminal 2 and performs input / output control (hereinafter referred to as proxy control) of the POS peripheral device. Specifically, from the control for displaying the proxy transaction processing screen 36B including the numeric keypad area 39 on the touch panel device 5 (see FIG. 4B), the product code acquired from the handy scanner 3 or the keyboard 4, and the numeric keypad area 39 Accounting processing based on the acquired merchandise price, generation of receipt print data (see FIG. 4B) and output including merchandise code, merchandise price, accounting processing result (accounting information), receipt issuance information and store information And do. That is, the proxy control unit 24 performs input / output control of peripheral devices for the mounting board 8 to execute the accounting process on behalf of the POS terminal 2. The accounting process of the proxy control unit 24 will be described in detail later.

  The recovery processing unit 25 performs a recovery process when the control switching unit 22 issues a switching command to switch the control of the mounted board 8 from the proxy control unit 24 to the normal control unit 23. Specifically, the product code stored in the history storage unit 15 described later is transmitted to the POS terminal 2. At this time, receipt print data corresponding to the transmitted product code is acquired from the POS terminal 2, but printing based on the receipt print data is not performed. The recovery process will also be described in detail later. Note that after the restoration process is completed, the mounted board 8 switches to the normal mode.

  The ROM 18 stores various control programs and various control data for the CPU 17 to perform various arithmetic processes. In particular, the ROM 18 stores a proxy control program 20 for the proxy control unit 24 to perform accounting processing and input / output control of peripheral devices as a proxy for the POS terminal 2. The RAM 19 is used as a work area when the CPU 17 performs various arithmetic processes.

  The history storage unit 15 stores a product code (input history) acquired from the handy scanner 3 or the keyboard 4 when proxy control is being executed by the proxy control unit 24. When the restoration process by the restoration processing unit 25 is completed, the stored product code is deleted.

  The switching operation unit 16 is for switching the control of the mounting board 8 between the normal control unit 23 and the substitute control unit 24, and is configured by, for example, a button type operation unit or a lever type operation unit. Yes. Thus, even when the POS terminal 2 is not out of order, for example, when there is an abnormality in the connection between the POS server 1 and the POS terminal 2, the accounting control processing is performed by switching to the proxy control of the proxy control unit 24. Can do. Note that the switching operation unit 16 may be provided in the keyboard 4 or the touch panel device 5.

  The printer main body 9 acquires the receipt print data generated by the POS terminal 2 or the receipt print data generated by the proxy control unit 24 of the mounting board 8 and prints the receipt 31. FIG. 3 is an example of a receipt printed by the printer body 9. FIG. 4A is an example of a receipt 31A based on receipt print data generated by the POS terminal 2, and FIG. 4B is an example of a receipt 31B based on receipt print data generated by the proxy control unit 24.

  As shown in FIG. 3A, a receipt 31A issued based on the receipt print data generated by the POS terminal 2 includes a store information print area 32A, a receipt issue information print area 33A, and a product information print area 34A. And accounting information printing area 35A. In the store information printing area 32A, “store name” and “store name” are printed. In the receipt issue information printing area 33A, “date and time” and “receipt issue number” are printed. In the product information print area 34A, “product name”, “number”, and “money” are printed. In the accounting information printing area 35A, “total amount”, “deposit amount”, and “change amount” are printed.

  On the other hand, as shown in FIG. 3B, a receipt 31B issued based on the receipt print data generated by the proxy control unit 24 includes a store information print area 32B, a receipt issue information print area 33B, and a product information print. An area 34B and a transaction information print area 35B are provided. The difference from the receipt 31A is that a “temporary receipt issue number” is printed instead of the “receipt issue number” in the receipt issue information print area 33B. In addition, “product code” is printed instead of “product name” in the product information printing area 34B. In this way, the receipt at the time of the accounting process by the proxy control unit 24 is different from the receipt at the time of the accounting process by the POS terminal 2, so that, for example, when a customer brings a receipt and comes to a return request, etc. It's easy to do. It is assumed that logo data for printing the store information printing area 32B is stored in both the POS terminal 2 and the mounting board 8.

  Returning to FIG. 1, the handy scanner 3 scans and inputs a product code which is a bar code printed or pasted on the product. On the other hand, the keyboard 4 inputs the product code when the store clerk manually inputs the product code consisting of a numeric string. The keyboard 4 is also used for inputting the number of products and the amount of deposit.

  The touch panel device 5 is used when the accounting process is performed by the POS terminal 2 (when the mounting board 8 is in the normal mode) or when the accounting process is performed by the proxy control unit 24 (mounted) The proxy transaction processing screen 36B is displayed (when the board 8 is in the proxy mode). FIG. 4A is an example of the normal transaction processing screen 36A, and FIG. 4B is an example of the proxy transaction processing screen 36B.

  As shown in FIG. 4A, the regular transaction processing screen 36A has a product information display area 37A and a transaction information display area 38A. In the product information display area 37A, “product code”, “product name”, “number”, “amount”, “manufacturer”, and the like are displayed. In the accounting information display area 38A, “total amount”, “deposit amount”, and “change amount” are displayed. That is, the product code input by the store clerk and the product information corresponding to the product code are displayed in the product information display area 37A, and the accounting process result (accounting information) of the POS terminal 2 is displayed in the accounting information display area 38A. In the normal accounting process screen 36A, the number of products may be directly input in the “number” field, or the same product code may be input a plurality of times. In the latter case, the number is automatically added to the “number” column.

  On the other hand, as shown in FIG. 4B, the proxy transaction processing screen 36B has a product information display area 37B, a transaction information display area 38B, a numeric keypad area 39, and a notification message display area 40. . Unlike the normal transaction processing screen 36A, “product name” and “maker” are not displayed in the product information print area 34A. Further, even if the same product code is input a plurality of times, the number is not automatically added to the “number” column. The numeric keypad 39 is for the store clerk to input the product price. It should be noted that the product price can be input using the keyboard 4. In the notification message display area 40, a message is displayed to notify that the POS terminal 2 is out of order and that the commodity price needs to be input. That is, the merchandise code and the merchandise amount input by the store clerk are displayed in the merchandise information display area 37 </ b> B, and the accounting processing result (accounting information) of the proxy control unit 24 is displayed in the accounting information display area 38. In this way, the proxy accounting screen 36B at the time of accounting processing by the proxy control unit 24 is different from the normal accounting screen 36A at the time of accounting processing by the POS terminal 2, and the tenkey area on the proxy accounting screen 36B It is possible to notify the store clerk of the failure of the POS terminal 2 immediately by changing the input operation method by displaying 39 and displaying the notification message.

  Next, the control switching process of the mounted board 8 will be described with reference to FIG. When the failure detection unit 21 detects a failure of the POS terminal 2 or the switching operation unit 16 performs a control switching operation from the normal control unit 23 to the proxy control unit 24. (S01: YES), the control switching unit 22 issues a control switching command from the normal control unit 23 to the proxy control unit 24 (S02). Thereafter, the mounted board 8 shifts to the proxy mode (S03). On the other hand, when the failure detection unit 21 has not detected a failure of the POS terminal 2 or when the switching operation unit 16 has not switched to the control of the proxy control unit 24 (S01: NO), the mode shifts to the normal mode. (S04).

  Next, a normal control process in the normal mode of the mounted board 8 will be described with reference to FIG. First, the mounting board 8 (normal control unit 23) issues a command to display the normal transaction processing screen 36A on the touch panel device 5 (S05). When the product code is acquired from the handy scanner 3 and the keyboard 4 (S06), the product code is output to the POS terminal 2 (S07). Thereafter, when receipt print data is acquired from the POS terminal 2 (S08), the receipt print data is output to the printer body 9 (S09).

  Next, a proxy control process in the proxy mode of the mounted board 8 will be described with reference to FIG. First, the mounting board 8 (proxy control unit 24) issues a command to display the proxy transaction processing screen 36B on the touch panel device 5 (S10). When the product code and the product price are acquired from the handy scanner 3 and the keyboard 4 (S11), the product code is stored in the history storage unit 15 (S12). On the other hand, the total price is calculated based on the product price (S13). When the deposit amount is acquired (S14), the change amount is calculated (S15), receipt print data is generated (S16), and output to the printer body 9 (S17). As described above, the proxy control by the proxy control unit 24 performs accounting processing and receipt print data generation on behalf of the POS terminal 2. However, the accounting processing does not acquire product information and performs “total amount” and “change”. It is a simple one that only calculates “amount”.

  Next, the recovery process of the POS system SY1 will be described with reference to FIG. When the mounting board 8 (control unit 14) issues a control switching command from the proxy control unit 24 to the normal control unit 23 by the control switching unit 22, the product code stored in the history storage unit 15 by the recovery processing unit 25 is stored in the POS terminal. 2 (S18). When acquiring the product code, the POS terminal 2 acquires product information corresponding to the product code from the POS server 1 (S19). Then, receipt print data is generated (S20) and transmitted to the mounting board 8. The mounting board 8 acquires the receipt print data (S21), and ends the restoration process without transmitting the receipt print data to the printer body 9 (S22). Note that the mounting board 8 determines that the restoration process has been completed when a predetermined time has elapsed since the receipt print data is no longer acquired. Thereafter, the mounting board 8 shifts to the normal mode. In this case, since the POS terminal 2 transmits the product code stored in the history storage unit 15 to the POS server 1, the history during proxy control can be reflected in the sales information. According to this configuration, the history under proxy control can be reflected in the sales information without changing the configuration of the POS terminal 2.

  Here, a modified example of the present embodiment will be described. The mounting board 8 according to the present modification includes a commodity control code stored in the receipt 31 of the POS terminal 2 in the proxy control program 20 stored in the ROM 18 of the control unit 14, a commodity price, a processing result (accounting information) of the accounting process, and A transmission program (not shown) for transmitting receipt issue information (hereinafter referred to as accounting processing information) to the POS server 1 is included. Then, the transaction processing information printed on the receipt during the proxy control by the proxy control unit 24 is stored in the history storage unit 15.

  With reference to FIG. 9, the restoration process of the POS system SY1 according to the present modification will be described. When the mounting board 8 (control unit 14) issues a control switching command from the proxy control unit 24 to the normal control unit 23 by the control switching unit 22, the transaction processing information stored in the history storage unit 15 by the restoration processing unit 25 is transmitted. The program is transmitted to the POS terminal 2 (S23). When the POS terminal 2 acquires the accounting process information and the transmission program (S24), the POS terminal 2 transmits the accounting process information to the POS server 1 according to the acquired transmission program (S25). In this case, the POS server 1 reflects the acquired transaction processing information in the sales information. On the other hand, the mounting board 8 ends the restoration process when all the accounting process information stored in the history storage unit 15 is transmitted to the POS terminal 2. Thereafter, the mounting board 8 shifts to the normal mode. According to this configuration, detailed information during the proxy control by the proxy control unit 24 can be reflected in the sales information.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. 10 and 11. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The modification according to the first embodiment is also applicable to the present embodiment. As shown in FIG. 10, the POS system SY2 of the present embodiment is different from the first embodiment in that the mounting board 8 is connected to the application server 50 via the network NT. Further, the mounting board 8 does not store the proxy control program 20 in the control unit 14 (ROM 18), and the proxy control unit 24 performs proxy control by downloading the proxy control program 51 included in the application server 50. .

  With reference to FIG. 11, the control switching process of the mounting board 8 according to the present embodiment will be described. When the failure detection unit 21 detects a failure of the POS terminal 2 or the switching operation unit 16 performs a control switching operation from the normal control unit 23 to the proxy control unit 24. (S26: YES), the proxy control program 51 is downloaded from the application server 50 (S27), and the proxy control program 51 is stored in the ROM 18. Then, the control switching unit 22 issues a control switching command from the normal control unit 23 to the proxy control unit 24 (S28). Thereafter, the mounted board 8 shifts to the proxy mode (S29). On the other hand, when the failure detection unit 21 has not detected a failure of the POS terminal 2 or when the switching operation unit 16 has not switched to the control of the proxy control unit 24 (S26: NO), the process proceeds to the normal mode. (S30).

  As described above, according to the second embodiment, the proxy control unit 24 of the mounting board 8 can execute proxy control according to the latest proxy control program 51. Further, since it is not necessary to store the proxy control program 51 in the ROM 18 in advance, the configuration for this can be omitted.

  The proxy control program 51 may be configured to operate on the application server 50 instead of downloading. According to this configuration, the control load on the mounting board 8 can be reduced.

According to the POS systems SY <b> 1 and SY <b> 2 described so far, the mounting board 8 can detect a failure of the POS terminal 2 and execute accounting processing in place of the POS terminal 2. That is, since the accounting process is not delayed when the POS terminal 2 breaks down, the loss of sales can be suppressed. Further, since the information on the accounting process at the time of the failure of the POS terminal 2 can be reflected in the POS server 1 by the recovery process, the loss of sales information can be prevented.
In addition, by realizing the above-described configuration with the mounting board 8, a POS system SY that can execute accounting processing even if the POS terminal 2 breaks down without changing the configuration of the conventional POS terminal 2 is realized. be able to.

  In each of the above embodiments, the mounting board 8 is mounted on the receipt printer 6. However, the mounting board 8 may be mounted on a POS peripheral device (keyboard 4, handy scanner 3, and touch panel device 5) other than the receipt printer 6. Good. Further, the mounting board 8 may be configured as an independent relay device.

  Note that it is possible to provide the processing steps of the POS system SY that can be executed in each of the above embodiments as a program. Further, the program can be provided by being stored in various recording media (CD-ROM, flash memory, etc.). That is, a program for causing a computer to function as each component of the POS system SY and a recording medium on which the program is recorded are also included in the scope of rights of the present invention.
