The auxiliary storage unit 13 may also store application programs. In this embodiment, the auxiliary storage unit 13 stores a transaction processing program PRA. The transaction processing program PRA is an application program that describes processing procedures related to information processing for processing transactions.

The transaction processing program PRA is typically stored in the auxiliary storage unit 13 when the transaction processing device 1 is transferred. However, the transaction processing program PRA may be written into the auxiliary storage unit 13 by the processor 11 in response to an operation by an arbitrary operator after the transaction processing device 1 is transferred. However, in this case, the auxiliary storage unit 13 of the transaction processing device 1 to be transferred may store a program of the same type with a different version from the transaction processing program PRA, or even if such a program is not stored. good. In the former case, a program later written to the auxiliary storage unit 13 is used in place of a similar program of a different version. Note that the transaction processing program PRA can be transferred by recording it on a removable recording medium such as a magnetic disk, magneto-optical disk, optical disk, semiconductor memory, etc., or by communication via a network.

The printer 14 issues various types of vouchers by printing various types of information on receipt paper. Various types of vouchers include receipts and the like representing the details of commercial transactions. The voucher issued by the receipt printer is discharged to the outside of the transaction processing device 1 from the receipt issuing port OA shown in FIG.

The scanner 2 and the touch panel 3 are connected to the interface unit 15. The interface unit 15 is connected to other external devices such as a payment terminal that executes payment processing using one or more of various payment methods such as credit card payment, electronic money payment, and barcode payment. In some cases. The interface unit 15 provides an interface for exchanging data between the scanner 2, the touch panel 3, or other connected external devices and the processor 11. As the interface unit 15, for example, a well-known interface device compliant with the USB (universal serial bus) standard can be used.

Communication unit 16 performs data communication via communication network 200 . The communication network 200 is, for example, a LAN (local area network). As the communication unit 16, if the communication network 200 is a LAN, a well-known communication device adapted to the LAN can be used.
The transmission path 17 includes an address bus, a data bus, a control signal line, and the like. The transmission path 17 transmits data and signals exchanged between the connected parts.

The scanner 2 includes a processor 21, a main storage unit 22, an auxiliary storage unit 23, a camera 24, an interface unit 25, a communication unit 26, a wireless communication unit 27, and a transmission path 28.

Note that the scanner 2 may include elements other than these elements.

A processor 21, a main storage unit 22, and an auxiliary storage unit 23 are connected through a transmission path 28 to constitute a computer for executing information processing to be executed by the scanner 2.
The functions of the processor 21, main storage unit 22, auxiliary storage unit 23, communication unit 26, and transmission path 28 are generally the same as those of the processor 11, main storage unit 12, auxiliary storage unit 13, communication unit 16, and transmission path 17. Therefore, its explanation will be omitted. However, the auxiliary storage unit 23 stores the scanner program PRB instead of the transaction processing program PRA. The scanner program PRB is an application program that describes processing procedures related to information processing to realize the functions of the scanner 2.

The auxiliary storage unit 23 also stores notification destination data DAA. The notification destination data DAA includes information for notifying the product code to a device other than the transaction processing device 1 that is determined as the notification destination of the product code. For example, in this embodiment, it is assumed that the coupon issuing device 4 and the monitoring device 5 are the notification destinations of the product code. In this case, the notification destination data DAA includes information such as an IP (internet protocol) address necessary for communicating with the coupon issuing device 4 via the communication network 200 using the communication unit 26 and the wireless communication unit 27. information such as a device address for communicating with the monitoring device 5 using the device address.

The camera 24 captures a light image entering from the window WA shown in FIG.
The interface unit 25 is connected to the interface unit 15 of the transaction processing device 1 . The interface unit 25, together with the interface unit 15, interfaces the processor 21 and the processor 11 to exchange data. As the interface unit 25, a well-known interface device conforming to the same standards as the interface unit 15 can be used.

The wireless communication unit 27 performs direct wireless data communication with a wireless communication device such as the monitoring device 5. As the wireless communication unit 27, an existing communication device based on, for example, Bluetooth (registered trademark) or Wi-Fi (registered trademark) can be used. Note that communication between the wireless communication unit 27 and the wireless communication device may be performed via an access point or the like.

FIG. 3 is a block diagram showing the main circuit configuration of the coupon issuing device 4. As shown in FIG.
The coupon issuing device 4 includes a processor 41 , a main storage unit 42 , an auxiliary storage unit 43 , a printer 44 , a communication unit 45 , and a transmission path 46 . The processor 41, main storage unit 42, auxiliary storage unit 43, printer 44, and communication unit 45 are connected to a transmission path 46. Note that the coupon issuing device 4 may include elements other than these elements.

A processor 41, a main storage unit 42, and an auxiliary storage unit 43 are connected through a transmission path 46 to constitute a computer for executing information processing to be executed by the coupon issuing device 4.
The functions of the processor 41, main storage unit 42, auxiliary storage unit 43, communication unit 45, and transmission path 46 are roughly equivalent to those of the processor 11, main storage unit 12, auxiliary storage unit 13, communication unit 16, and transmission path 17. Therefore, its explanation will be omitted. However, the auxiliary storage unit 43 stores a coupon issuing program PRC instead of the transaction processing program PRA. The coupon issuing program PRC is an application program that describes processing procedures related to information processing for realizing the functions of the coupon issuing device 4.

The printer 44 creates various coupons by printing various information on coupon paper. The coupon created by the printer 44 is discharged to the outside of the coupon issuing device 4 from the coupon issuing port OB shown in FIG.

FIG. 4 is a block diagram showing the main circuit configuration of the monitoring device 5. As shown in FIG.
The monitoring device 5 includes a processor 51, a main storage unit 52, an auxiliary storage unit 53, a camera 54, a wireless communication unit 55, and a transmission path 56. The processor 51, main storage unit 52, auxiliary storage unit 53, camera 54, and wireless communication unit 55 are connected to a transmission path 56. Note that the monitoring device 5 may include elements other than these elements.

A processor 51, a main storage unit 52, and an auxiliary storage unit 53 are connected through a transmission path 56 to constitute a computer for executing information processing to be executed by the monitoring device 5.
The functions of the processor 51, the main storage unit 52, the auxiliary storage unit 53, and the transmission path 46 are generally the same as those of the processor 11, the main storage unit 12, the auxiliary storage unit 13, and the transmission path 17, so the description thereof will be omitted. However, the auxiliary storage unit 53 stores a monitoring program PRD instead of the transaction processing program PRA. The monitoring program PRD is an application program that describes processing procedures related to information processing to realize the functions of the monitoring device 5.
The camera 54 takes a bird's-eye view of the vicinity of the transaction processing device 1 in order to take a picture of the operator's actions when holding a product in front of the window WA of the scanner 2 or operating the touch panel 3.

The wireless communication unit 55 wirelessly communicates with the wireless communication unit 27 of the scanner 2 . The wireless communication unit 55, together with the wireless communication unit 27, enables data to be exchanged between the processors 51 and 21. As the wireless communication unit 55, an existing communication device compliant with the same standards as the wireless communication unit 27 can be used.

Next, the operation of the POS terminal system 100 configured as above will be explained.
When the scanner 2 is activated, the processor 21 starts executing information processing based on the scanner program PRB.
FIG. 5 is a flowchart of information processing by the processor 21. Note that the contents of the processes described below are merely examples, and the order of some processes may be changed, some processes may be omitted, or other processes may be added as appropriate.

As ACT1, the processor 21 activates the camera 24. Thereby, the camera 24 repeatedly takes pictures at predetermined time intervals and stores the obtained images in the main storage unit 22 or the auxiliary storage unit 23. Note that the camera 24 may take moving images or may intermittently repeatedly take still images. Note that the processor 21 may cause the camera 24 to perform the photographing operation only once here. In this case, the processor 21 repeats ACT1 and subsequent steps in a case described later in which the processing after ACT2 is re-executed.
In ACT2, the processor 21 executes a barcode extraction process using the latest image stored by the camera 24 in the main storage unit 22 or the auxiliary storage unit 23 as a processing target. The barcode extraction process is a process that attempts to extract a barcode reflected in an image to be processed, and the details thereof may be the same as, for example, well-known processes.

In ACT3, the processor 21 checks whether the barcode extraction has been successful. Here, unless a barcode is reflected in the image targeted for the barcode extraction process performed immediately before in ACT2, the barcode cannot be extracted by the barcode extraction process. Therefore, in this case, the processor 21 determines NO, and repeats ACT2 and subsequent steps in the same manner as described above. That is, the processor 21 repeatedly performs the barcode extraction process in ACT2 until the barcode can be extracted.

When the operator should cause the transaction processing device 1 to acquire a membership code or the like as an identifier of the operator, the operator holds up a barcode representing barcode data including the relevant membership code over the window WA. When the operator wants the transaction processing device 1 to acquire a product code as an identifier of a product to be registered as a transaction product, the operator holds up a barcode representing barcode data including the corresponding product code over the window WA. When the barcode held up in the window WA is reflected in the image taken by the camera 24, the processor 21 can extract the barcode through the barcode extraction process in ACT2. If the barcode can be extracted in ACT2, the processor 21 determines YES in ACT3, and proceeds to ACT4.

In ACT4, the processor 21 analyzes the barcode extracted from the image and obtains barcode data represented by the barcode. If the barcode including the product code is obtained here, the processor 21 has obtained the product code. As the processor 21 executes information processing based on the scanner program PRB, the computer having the processor 21 as its core functions as an acquisition means.

In ACT5, the processor 21 notifies the transaction processing device 1 of the barcode data obtained through the above analysis. Specifically, the processor 21 generates notification data including the barcode data obtained through the above analysis, and sends this notification data from the interface unit 25 to the transaction processing device 1. Note that the processor 21 notifies the transaction processing device 1 regardless of the content of the barcode data. Here, if the barcode data included in the notification data includes a product code, the transaction processing device 1 will be notified of the product code. In this way, by the processor 21 executing information processing based on the scanner program PRB, the computer with the processor 21 as the central part can perform the first processing to notify the transaction processing device 1, which is the first device, of the product code as the identification information. Functions as a means of notification.

The notification data is taken into the transaction processing device 1 by the interface unit 15. In response to this, the processor 11 appropriately performs processing using the barcode data included in the captured notification data. For example, if the barcode data includes a membership code, the processor 11 identifies the operator based on the membership code. For example, if the barcode data includes a product code, the processor 11 registers the product identified by the product code as a transaction product. Such processing in the transaction processing device 1 is realized by information processing by the processor 11 based on the transaction processing program PRA, and may be similar to processing performed in another existing POS terminal, for example.

After the processor 21 in the scanner 2 finishes notifying the transaction processing device 1 of the barcode data, it proceeds to ACT6.
In ACT6, the processor 21 checks whether the barcode data obtained in ACT4 includes a product code. If the processor 21 confirms that the product code is not included, the processor 21 determines NO and repeats the processing from ACT2 onwards. However, if the processor 21 confirms that the product code is included, it determines YES in ACT6 and proceeds to ACT7.
In other words, processor 21 notifies only transaction processing device 1 of barcode data that does not include a product code. However, the processor 21 may omit ACT6 and proceed to ACT7 even if the barcode data obtained in ACT4 does not include a product code.

In ACT7, the processor 21 checks whether there is a notification destination setting. For example, the processor 21 checks whether information regarding the notification destination is included in the notification destination data DAA, and if it is confirmed that the information is not included, the processor 21 determines NO and repeats the processing from ACT2 onwards. However, if the processor 21 confirms that information regarding the notification destination is included, it determines YES in ACT7 and proceeds to ACT8.

In ACT8, the processor 21 selects one of the set notification destinations.
In ACT9, the processor 21 notifies the selected notification destination of the barcode data obtained in ACT4. For example, the processor 21 generates notification data including the corresponding barcode data and transmits it to the selected notification destination. For example, if the coupon issuing device 4 is selected, the processor 21 causes the communication unit 26 to send notification data addressed to the IP address included in the notification destination data DAA to the communication network 200. For example, if the monitoring device 5 is selected, the processor 21 causes the wireless communication unit 27 to wirelessly transmit notification data addressed to the device address included in the notification destination data DAA. In this way, by the processor 21 executing information processing based on the scanner program PRB, the computer with the processor 21 as the central part is able to send the product code as the identification information to the notification destination device as the second device. It functions as the notification means of 2.

In ACT10, the processor 21 checks whether there is any unselected notification destination. Then, if the notification destination data DAA includes information regarding multiple notification destinations, and there is a notification destination that has not yet been selected in ACT8, it is determined as YES in ACT10, and from ACT8 onwards. Repeat as above. However, when executing ACT8 for the second time or later, the processor 21 selects a notification destination different from that selected in ACT8 up to that time. In this way, if a plurality of notification destinations are set, the processor 21 notifies each of the notification destinations of the barcode data. If the processor 21 finishes notifying all notification destinations and proceeds to ACT10, it determines NO, and repeats the processing from ACT2 onwards in the same manner as described above. In other words, the processor 21 notifies the transaction processing device 1 of the barcode data represented by the barcode every time the barcode is held over the window WA. Further, the processor 21 also notifies a notification destination other than the transaction processing device 1 of the barcode data represented by the barcode every time the barcode of the product is held up on the window WA.

If barcode data including a product code is notified multiple times while registering transaction products related to one transaction, the processor 11 in the transaction processing device 1 registers the products included in the barcode data. Each product identified by the code is added to the list as a transaction product. If the operator instructs the transaction to be made through a predetermined operation on the touch panel 3, the processor 11 performs, for example, well-known accounting processing, and then completes the processing of one transaction. As the processor 11 executes information processing based on the transaction processing program PRA, the computer having the processor 11 as its core functions as an updating means.
In this way, the transaction processing device 1, scanner 2, and touch panel 3 realize the basic function of processing transactions in the POS terminal system 100, and the coupon issuing device 4 and monitoring device 5 are not essential.

Now, in the coupon issuing device 4, when notification data addressed to the IP address of the coupon issuing device 4 is transmitted via the communication network 200, the communication unit 45 takes in this notification data. In response to this, the processor 41, for example, checks the product code included in the notification data, and if a predetermined condition is satisfied regarding the product identified by this notification code, a coupon corresponding to the condition that is satisfied is issued. is printed by the printer 44. Processing in response to receiving notification of such barcode data is realized as information processing by the processor 41 based on the coupon issuing program PRC. The content of information processing by the processor 41 based on the coupon issuing program PRC may be determined as appropriate by the creator of the coupon issuing program PRC. Thus, the coupon issuing device 4 is an example of a processing device that executes a process for issuing a coupon, which is a predetermined process different from updating a list, based on the notified product code.

In the monitoring device 5, when notification data addressed to the device address of the monitoring device 5 arrives, the wireless communication unit 55 takes in the notification data. In response to this, the processor 51 checks, for example, based on the image taken by the camera 54, whether the operator who held up the product's barcode over the window WA is taking the correct next action. Processing in response to receiving notification of such barcode data is realized as information processing by the processor 51 based on the monitoring program PRD. The content of information processing by the processor 51 based on the monitoring program PRD may be determined as appropriate by the creator of the monitoring program PRD. Thus, the monitoring device 5 is an example of a processing device that executes a process for monitoring, which is a predetermined process different from updating a list, based on the notified product code.

In this way, the coupon issuing device 4 and the monitoring device 5 can issue and monitor coupons related to the transaction processing by performing information processing independently of the transaction processing in the transaction processing device 1. In other words, by adding a coupon issuing device 4 to the basic configuration consisting of a transaction processing device 1, a scanner 2, and a touch panel 3, and setting the coupon issuing device 4 as a notification destination in the scanner 2, the coupon issuing function can be easily performed. can be added. Additionally, by adding a monitoring device 5 to the basic configuration consisting of the transaction processing device 1, scanner 2, and touch panel 3, and setting the monitoring device 5 as a notification destination in the scanner 2, the function of monitoring the operator's behavior is facilitated. can be added to.

Thus, according to the present embodiment, the POS terminal system 100, which is constructed to acquire the product code of a product and perform processing related to the product code, can be configured to additionally perform processing other than the above processing. It can be easily changed.

This embodiment can be modified in various ways as follows.
As the second device, only one of the coupon issuing device 4 and the monitoring device 5 may be used. Further, as the second device, another arbitrary device may be used instead of or in addition to the coupon issuing device 4 and the monitoring device 5.

The device used as the second device may be connected to the interface unit 25.

Scanner 2 may also utilize other types of well-known devices, such as those that utilize reflection of laser light to read bar codes, instead of or in addition to using camera 24.

For example, even in input devices that input a product code without scanning, such as by pressing a button associated with a product code or inputting a character string corresponding to the product code, ACT5 and later The processing can be performed in the same manner as in the above embodiment.

Each function realized by the processors 11, 21, 41, and 51 through information processing can be partially or entirely realized by hardware that executes information processing not based on a program, such as a logic circuit. Further, each of the above functions can also be realized by combining software control with hardware such as the above logic circuit.
