Next, the hardware configuration of the product sales data processing device 1 will be described. FIG. 5 is a diagram showing an example of the hardware configuration of the product sales data processing device 1.

As shown in FIG. 5, the product sales data processing device 1 includes the main body 10, the main display 20, the printer 30, and the input device 40 described above. The main display 20, the printer 30, and the input device 40 are connected to the main body 10. The main display 20, the printer 30, and the input device 40 are operated by the electric power supplied from the main body 10, and the operation is controlled by the main body 10.

The main body 10 includes a computer configuration such as a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, and a storage unit 14. The main body 10 includes a communication unit 15, a power supply unit 16, an internal power supply 17, and the like.

The CPU 11 comprehensively controls the operation of the main body 10 (commodity sales data processing device 1) by expanding the program stored in the ROM 12 and the storage unit 14 into the RAM 13 and executing the program. The ROM 12 stores files such as various programs and various data used in the processing of the various programs. The RAM 13 temporarily stores the data being worked on.

The storage unit 14 is a storage device including a non-volatile storage medium such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The storage unit 14 stores various programs such as an OS (Operating System) and various data files such as setting information. For example, the storage unit 14 stores a product master (not shown) registered in association with a product code, a product name, a unit price, etc. that identify the product for each type of product to be sold. In addition, the storage unit 14 stores sales data generated for each transaction by executing the product sales data processing.

The communication unit 15 is a communication interface for communicating with an external device according to a wired communication standard or a wireless communication standard. For example, the communication unit 15 exchanges various data with a server device (store server) connected to the network in the store.

The power supply unit 16 supplies the electric power supplied from the external power supply OP via the internal power supply 17 and the adapter AD to each unit of the product sales data processing device 1 via a power supply line (not shown). Specifically, the power supply unit 16 has a switching circuit 16a for switching the power supply, and supplies power supplied from either the internal power supply 17 or the external power supply OP to each part of the product sales data processing device 1. Supply. It is assumed that the power supply unit 16 is configured to maintain the power supply to the input device 40 even when the main body unit 10 is shut down due to a power failure process described later.

The internal power source 17 is a power source for a battery, a secondary battery, or the like. In the product sales data processing device 1, the main body 10 can be safely terminated (shut down) by using the internal power supply 17 when a power failure occurs in the external power supply OP. The capacity of the internal power supply 17 is not particularly limited, but at least it is assumed to have a capacity capable of executing the power failure processing described later.

On the other hand, the input device 40 includes the keyboard 41, the sub-display 42, and the card reader 43 described above. Further, the input device 40 includes a computer configuration such as a CPU 44, a ROM 45, a RAM 46, and a storage unit 47.

The CPU 44 comprehensively controls the operation of the input device 40 by expanding the program stored in the ROM 45 and the storage unit 47 into the RAM 46 and executing the program. The ROM 45 stores files such as various programs and various data used in the processing of the various programs. The RAM 46 temporarily stores the data being worked on.

The storage unit 47 is a storage device including a non-volatile storage medium such as an HDD or SSD. The storage unit 47 stores various programs that can be executed by the CPU 44 and various data files such as setting information. For example, the storage unit 47 stores a product master (not shown) similar to the main body unit 10. Further, the storage unit 47 stores the sales data generated for each transaction by executing the product sales data processing.

The power consumption of the input device 40 is smaller than the power consumption of the main body 10 and the entire product sales data processing device 1 excluding the input device 40.

Next, the functional configuration of the product sales data processing device 1 will be described. FIG. 6 is a diagram showing an example of the functional configuration of the product sales data processing device 1.

The main body 10 includes a first display control unit 101, a first data processing unit 102, a power failure detection unit 103, and other functional units realized by cooperation between the CPU 11 and a program stored in the storage unit 14 and the like. A power switching unit 104 and a power failure processing unit 105 are provided. The power failure detection unit 103 and the power switching unit 104 may be realized by the cooperation of the CPU 11 and the power supply unit 16, or may be realized by the hardware included in the power supply unit 16.

The first display control unit 101 controls the screen to be displayed on the main display 20. For example, the first display control unit 101 displays a screen including an operator for instructing the start of registration of a product and an operator for instructing the end of registration. In addition, the first display control unit 101 cooperates with the first data processing unit 102 to display the product name, total amount, payment amount, and the like of the registered products on the main display 20.

Further, the first display control unit 101 controls the screen to be displayed on the sub display 42 by cooperating with the second display control unit 402 of the input device 40. For example, the first display control unit 101 causes the sub display 42 to display an operation screen related to the content displayed on the main display 20.

The first data processing unit 102 executes data processing (product sales data processing) related to product sales. Specifically, the first data processing unit 102 executes a sales registration process for registering a product to be sold and a settlement process for settlement of the registered product as product sales data processing.

In the sales registration process, the first data processing unit 102 accepts the input of a product code that can identify the product purchased by the customer, and identifies the product corresponding to the product code from the product master. Then, the first data processing unit 102 registers (stores) the product code of the specified product in the RAM 13 or the like in association with the number of points sold, the amount of money, or the like of the product.

In the sales registration process, the method of inputting the product code is not particularly limited. For example, the first data processing unit 102 may accept the input of the product code via the keyboard 41 of the input device 40. Further, a scanner device capable of reading a code symbol and a reader device capable of reading an RFID tag are connected to the product sales data processing device 1, and the product code is input via these devices (peripheral devices). It may be configured as such. In this case, the first data processing unit 102 accepts the product code obtained by reading the code symbol attached to the product or the RFID tag as input data.

Further, in the settlement process, the first data processing unit 102 executes the settlement process of the product based on the data of each product registered in the sales registration process. Specifically, the first data processing unit 102 executes a settlement process in which the total amount of each product registered in one transaction is settled at the amount paid by the customer (payment amount). The payment method of the payment amount is not particularly limited, and cash payment or electronic money payment may be used.

When the product sales data processing for one transaction is completed, the first data processing unit 102 stores the sales data indicating the breakdown of the transaction in the storage unit 14. The sales data includes, for example, the product code and total amount of each product registered for sale, the payment amount and change amount paid by the customer, the transaction date and time, and the like. In addition, the first data processing unit 102 causes the printer 30 to print the details of the transaction as a receipt.

Further, when the first data processing unit 102 receives the sales data from the input device 40 when recovering from the power failure state described later, the first data processing unit 102 stores the received sales data in the storage unit 14.

The power failure detection unit 103 detects a power failure of the external power supply OP. Specifically, the power failure detection unit 103 monitors the power supplied from the external power supply OP, and detects that a power failure has occurred when the voltage (or current) value falls below a predetermined threshold value. The threshold value is set in advance based on, for example, the value of the voltage (or current) required for the product sales data processing device 1 to operate normally.

The power switching unit 104 switches the power supply source of power from the external power supply OP to the internal power supply 17 in response to the detection of the occurrence of a power failure by the power failure detection unit 103. Specifically, the power switching unit 104 sets the connection destination of the switching circuit 16a to the external power supply OP in a state where a power failure has not occurred, that is, in a state where the power supply from the external power supply OP is normal. The power supply is an external power supply OP. When the power failure detection unit 103 detects the occurrence of a power failure, the power supply switching unit 104 switches the connection destination of the switching circuit 16a to the internal power supply 17, so that the power supply source is the internal power supply 17.

Further, when the external power supply OP recovers from the power failure state, the power supply switching unit 104 switches the connection destination of the switching circuit 16a to the external power supply OP to return the power supply source to the external power supply OP. The power failure detection unit 103 and the power switching unit 104 function together with the power supply unit 16 (switching circuit 16a) as an example of the power supply means.

The power failure processing unit 105 is an example of the power failure processing means and the operation mode switching means. The power failure processing unit 105 executes a power failure process for stopping the operation of the main body 10 on the condition that the power failure detection unit 103 detects the occurrence of a power failure. Specifically, when the power failure detection unit 103 detects the occurrence of a power failure, the power failure processing unit 105 transmits a control signal instructing the switching of the operation mode to the input device 40, and starts the power failure processing. The power failure processing unit 105 may be configured to transmit the above control signal to the input device 40 on condition that the power supply of the supply source is switched to the internal power supply 17 by the power supply switching unit 104.

When the power failure processing is started, the power failure processing unit 105 saves the data or the like in the middle of the transaction held by the RAM 13 in the storage unit 14. Here, the power failure processing unit 105 may transmit the data in the middle of the transaction held by the RAM 13 to the input device 40 together with the operation mode switching instruction. Further, the power failure processing unit 105 may transmit the product master stored in the storage unit 14 to the input device 40 together with the operation mode switching instruction.

When the data saving is completed, the power failure processing unit 105 shuts down the main body 10 in order to stop the operation of the main body 10. As a result, the main body 10 (main display 20 and printer 30) stops operating, so that the power consumption of the product sales data processing device 1 also decreases.

In order to make it possible to identify whether or not the shutdown of the main body 10 is due to power failure processing, the power failure processing unit 105 stores flag information (hereinafter, power failure flag) or the like indicating that the power failure processing has been executed in the storage unit 14. It may be a configuration to be memorized. Further, when this configuration is adopted, the CPU 11 of the main body 10 confirms the presence or absence of the power failure flag when the main body 10 is started after returning from the power failure state, and if the power failure flag exists, the operation mode is switched. The instruction control signal may be transmitted to the input device 40.

On the other hand, the input device 40 of the product sales data processing device 1 has an operation mode switching unit 401 and a second display control unit 402 as functional units realized by cooperation between the CPU 44 and the program stored in the storage unit 47 or the like. A second data processing unit 403 and a return processing unit 404 are provided.

The operation mode switching unit 401 is an example of the operation mode switching means. The operation mode switching unit 401 switches the operation mode of the input device 40 according to the state of the main body unit 10. Specifically, the operation mode switching unit 401 operates the input device 40 in the device mode while the main body unit 10 is operated by the electric power supplied from the external power supply OP. The device mode is an operation mode for operating the input device 40 as a peripheral device (input / output device) of the main body 10, and corresponds to the first operation mode. In the device mode, the input device 40 transmits a signal according to the operation content received via the keyboard 41 or the sub-display 42 to the main body 10. Further, in the device mode, the input device 40 displays a screen corresponding to the display signal transmitted from the first display control unit 101 of the main body 10 on the sub display 42.

Further, the operation mode switching unit 401 switches the operation mode of the input device 40 from the device mode to the stand-alone mode when the power supply of the supply source is switched to the internal power supply 17. The stand-alone mode is an operation mode capable of operating independently of the main body 10, and corresponds to the second operation mode. In the stand-alone mode, the input device 40 can execute the product sales data processing by the input device 40 alone by the function of the second data processing unit 403 described later.

In the present embodiment, the device mode is switched to the stand-alone mode on the condition that the operation mode is switched from the main body 10, but the switching condition is not limited to this. .. For example, the operation mode switching unit 401 may switch to the stand-alone mode on the condition that the communication with the main body unit 10 is interrupted, that is, on the condition that the operation of the main body unit 10 is stopped.

Further, when the operation mode switching unit 401 confirms that the main body unit 10 is activated by the power supplied from the external power supply OP, the operation mode switching unit 401 returns the operation mode of the input device 40 from the stand-alone mode to the device mode. For example, the operation mode switching unit 401 switches from the stand-alone mode to the device mode on the condition that the operation mode switching is instructed by the main body unit 10. The conditions for switching to the device mode are not limited to this. For example, the operation mode switching unit 401 may switch to the device mode on the condition that the communication with the main body unit 10 is restored, that is, on the condition that the main body unit 10 is activated. Further, the device mode may be switched on condition that a predetermined operation is performed via the keyboard 41.

The second display control unit 402 controls the screen to be displayed on the sub display 42. Specifically, the second display control unit 402 causes the sub-display 42 to display various screens related to product sales data processing in accordance with the control of the main body unit 10 (first display control unit 101) under the device mode. .. Further, the second display control unit 402 cooperates with the second data processing unit 403 in the stand-alone mode to display various screens related to the product sales data processing on the sub display 42. The second display control unit 402 may display information indicating the operating mode being executed on the sub-display 42 in response to the switching operation of the operation mode switching unit 401.

The second data processing unit 403 is an example of the data processing means, and is a functional unit activated under the stand-alone mode. The second data processing unit 403 has the same function as the first data processing unit 102 of the main body unit 10, and executes the above-mentioned product sales data processing. That is, in the input device 40 that operates in the stand-alone mode, the product sales data processing can be executed by the input device 40 alone by the function of the second data processing unit 403. When the second data processing unit 403 receives data in the middle of a transaction from the main body unit 10, the second data processing unit 403 shall take over the transaction (commodity sales data processing) based on the data. Further, when the second data processing unit 403 receives the product master from the main body unit 10, the second data processing unit 403 stores the product master in the storage unit 47 and executes the product sales data processing based on the product master. ..

When the product sales data processing for one transaction is completed, the second data processing unit 403 stores the sales data indicating the breakdown of the transaction in the storage unit 47, similarly to the first data processing unit 102. The sales data may include flag information or the like indicating that the transaction has been processed by the input device 40.

When the product sales data processing is executed by the input device 40 alone, the product code is input via the keyboard 41, but the input method of the product code is not limited to this. For example, the input device 40 is provided with a connector such as USB (Universal Serial Bus) capable of connecting the above-mentioned scanner device, reader device, or the like, and the product code is input via the device connected to the connector. May be good. In this case, the scanner device and the reader device are preferably bus-powered devices that are driven by using the electric power supplied from the connector.

Further, when the product sales data processing is executed by the input device 40 alone, the receipt cannot be issued because the printer 30 cannot be used. However, for example, the following alternative method may be used. The second data processing unit 403 converts the contents of the transaction into a two-dimensional code, and displays the two-dimensional code on the sub-display 42. Then, by having the customer read the two-dimensional code displayed on the sub-display 42 with a mobile terminal such as a smartphone owned by the customer, the contents of the transaction are electronically provided to the customer instead of the paper receipt.

As another method, when the customer's identification information is input via the card reader 43 at the time of transaction, the identification information is included in the sales data and stored. Then, after recovering from the power failure state, the sales data is transmitted from the input device 40 to the main body 10. Then, the CPU 11 of the main body 10 sets the contents of the sales data as an electronic receipt to a destination such as an e-mail address stored in advance in association with the identification information based on the identification information included in the transmitted sales data. Send.

As a result, the product sales data processing device 1 can perform a transaction (product sales data processing) using the input device 40 even after the main body 10 is shut down due to the occurrence of a power failure. Further, since the power consumption can be suppressed by operating the input device 40 rather than operating the main body 10, the product sales data processing can be continued for a longer time. Further, even if the transaction (commodity sales data processing) in the main body 10 is interrupted due to the occurrence of a power failure, the transaction can be taken over by the input device 40, so that the processing can be facilitated. can.

When the main body 10 recovers from the power failure state, the return processing unit 404 transmits the sales data stored in the storage 47 to the main body 10. Specifically, when the return processing unit 404 confirms that the main body unit 10 is activated by the power supply from the external power supply OP, the return processing unit 404 transmits the sales data stored in the storage unit 47 to the main body unit 10. As a result, the return processing unit 404 can aggregate the sales data of the transaction (commodity sales data processing) executed by the input device 40 into the main body unit 10. The return processing unit 404 may confirm that the main body 10 is started by the power supply from the external power supply OP by the same method (condition) as the operation mode switching unit 401 described above.

Next, the operation of the product sales data processing device 1 will be described with reference to FIGS. 7 and 8.

FIG. 7 is a flowchart showing an example of processing executed by the product sales data processing device 1 when a power failure occurs. As a premise of this processing, it is assumed that the product sales data processing device 1 is operating by the electric power supplied from the external power supply OP.

The power failure detection unit 103 of the main body 10 monitors the power supplied from the external power supply OP and determines whether or not a power failure has occurred (step S11). When the amount of power supplied from the external power supply OP is equal to or greater than a predetermined threshold value, the power failure detection unit 103 repeatedly executes step S11 (step S11; No). The first data processing unit 102 can execute the product sales data processing until the power failure detection unit 103 detects the occurrence of a power failure.

When the amount of power supplied from the external power supply OP falls below the threshold value, the power failure detection unit 103 detects that a power failure has occurred (step S11; Yes). When the occurrence of a power failure is detected, the power supply switching unit 104 switches the power supply of the supply source from the external power supply OP to the internal power supply 17 (step S12).

Subsequently, the power failure processing unit 105 starts the power failure processing after instructing the input device 40 to switch the operation mode (step S13). Then, the power failure processing unit 105 saves the data on the RAM 13 to the storage unit 14 and shuts down the main body unit 10 (step S14). The power failure processing unit 105 stores the power failure flag in the storage unit 14 before shutting down the main body unit 10.

On the other hand, the input device 40 operates in the device mode until the main body 10 instructs the switching of the operation mode (step S21 → step S22; No). When the main body 10 instructs the switching of the operation mode (step S22; Yes), the operation mode switching unit 401 switches the operation mode of the input device 40 from the device mode to the stand-alone mode (step S23). With the switch to the stand-alone mode, the second data processing unit 403 is activated (step S24). After step S24, the input device 40 can execute the product sales data processing independently of the main body 10.

FIG. 8 is a flowchart showing an example of processing executed by the product sales data processing device 1 when returning from a power failure state. As a premise of this process, it is assumed that the input device 40 is operating in the stand-alone mode. Further, in this process, an example of instructing the input device 40 to switch the operation mode from the main body 10 based on the power failure flag stored when the power failure occurs will be described.

When the main body 10 is activated after recovering from the power failure (step S31), the CPU 11 instructs the input device 40 to switch the operation mode (step S32). If the power failure flag does not exist in the storage unit 14, the CPU 11 skips steps S32 and S33 and ends this process.

On the other hand, the input device 40 operates in the stand-alone mode until the main body 10 instructs the switching of the operation mode (step S41 → step S42; No). When the main body 10 instructs to switch the operation mode (step S42; Yes), the return processing unit 404 transmits the sales data stored in the storage unit 47 to the main body 10 (step S43).

Subsequently, the operation mode switching unit 401 switches the operation mode of the input device 40 from the stand-alone mode to the device mode (step S44). With the switching to the device mode, the second data processing unit 403 is invalidated (step S45).

When the first data processing unit 102 of the main body unit 10 receives the sales data from the input device 40, the first data processing unit 102 stores the sales data in the storage unit 14 (step S33).

Although the embodiments of the present invention have been described above, the above-described embodiments are presented as examples and are not intended to limit the scope of the invention. The above-mentioned novel embodiment can be implemented in various other embodiments, and various omissions, replacements, changes, and combinations can be made without departing from the gist of the invention. The above-described embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.

For example, in the above embodiment, the input device 40 is switched to the stand-alone mode when a power failure occurs (switching to the internal power supply 17), but the user may be asked to confirm the necessity of the switching. When this configuration is adopted, for example, the power failure processing unit 105 or the operation mode switching unit 401 causes the main display 20 or the sub display 42 to display a screen for confirming the switching to the stand-alone mode. Then, the power failure processing unit 105 or the operation mode switching unit 401 instructs the input device 40 to switch the operation mode or switches the input device 40 to the stand-alone mode when the user performs an operation instructing the switching. ..

Further, in the above embodiment, the sales data is transmitted from the input device 40 to the main body 10 when returning from the power failure state, but when the input device 40 holds the data in the middle of the transaction in the RAM 46, The data may also be transmitted to the main body 10. When the first data processing unit 102 of the main body unit 10 receives data in the middle of a transaction from the input device 40, the first data processing unit 102 shall take over the transaction (commodity sales data processing) based on the data. As a result, the data in the middle of the transaction can be mutually inherited between the main body 10 and the input device 40, so that the transaction can proceed smoothly.

Further, in the above embodiment, the product sales data processing can be performed using the input device 40 even after the main body 10 is shut down due to the power failure processing, but the operating time of the input device 40 is the remaining battery level of the internal power supply 17. Depends on. Therefore, in order to avoid forced termination of the input device 40 due to the battery of the internal power supply 17, the sub-display 42 may be configured to display the remaining time during which the input device 40 can operate. When adopting this configuration, for example, the CPU 44 of the input device 40 is preset in cooperation with the power supply unit 16 according to the remaining time calculated from the remaining battery level of the internal power supply 17 and the battery capacity of the internal power supply 17. The remaining time may be displayed on the sub display 42 while counting down. When the remaining time reaches zero, the CPU 44 saves the data on the RAM 46 to the storage unit 47, and then safely stops the operation of the input device 40.

Further, the program executed by each device of the above-described embodiment is provided by incorporating it into a storage medium included in the device in advance, but the present invention is not limited to this. For example, the program is recorded on a computer-readable recording medium such as a CD-ROM, flexible disk (FD), CD-R, or DVD (Digital Versatile Disk) in an installable or executable format. It may be configured to provide. Further, the storage medium is not limited to a medium independent of a computer or an embedded system, but also includes a storage medium in which a program transmitted by a LAN, the Internet, or the like is downloaded and stored or temporarily stored.

Further, the program executed by each device of the above embodiment may be stored on a computer connected to a network such as the Internet and provided by downloading via the network, or may be provided via a network such as the Internet. It may be configured to be distributed.
