Description

Embodiments of the present invention relate to an article information processing device.

Conventionally, a product registration device including an RFID (Radio Frequency Identification) reader and a barcode reader is known. This type of product registration device registers products by placing a plurality of products in the reading area of an RFID reader and reading tag information from RF tags (hereinafter referred to as wireless tags). In addition, if the tag information on the wireless tag attached to a product cannot be read because metal overlaps with it, or if the wireless tag is damaged, a barcode reader will be able to read the barcode attached to the product. The product is registered by reading the information (Patent Document 1).

The product registration device described in Patent Document 1 detects the usage state of a handy barcode reader that is held and used by a user, and invalidates the tag information read by the RFID reader when the barcode reader is used. do. The above product registration device reads tag information when reading code information to prevent double product registration processing.

Patent Document 1 discloses, as an example of a method for detecting the usage status of a barcode reader, a method in which a barcode reader is provided with a wireless tag, and a stand for the barcode reader is provided with a separate RFID reader. This product registration device determines that the barcode reader is in use when the RFID reader provided on the stand no longer reads the wireless tag provided on the barcode reader.

However, since the configuration of the above conventional technology uses an RFID reader, even if the barcode reader is removed from the stand, if the barcode reader is located within the reading range of the RFID reader, the barcode reader is The device reads the wireless tag that was sent to it. Therefore, even if the barcode reader is removed, it will be determined that it is not in use, and as a result, there is a possibility that the same product may be registered twice using tag information and code information. .

For example, when reading a product with a barcode reader, the moment the product is picked up and moved, the overlap between the wireless tag and the metal disappears, and the tag information on the wireless tag attached to the product is read by the wireless tag reader. There is. For this reason, in this type of device, it is desirable to quickly detect a state in which a barcode reader can be used, and to suppress double processing of tag information and code information related to the same article.

The problem to be solved by the present invention is to provide an information processing device that can suppress double processing of tag information and code information related to the same article.

(First embodiment)
The article information processing device of the first embodiment will be described below. This embodiment is an example in which the article information processing device is applied to a self-checkout device that performs product registration processing and accounting processing. However, the present invention is not limited to this, and can be applied to, for example, an inventory management device that manages inventory, a parts management device that manages parts, and the like.

FIG. 1 is a perspective view showing an example of the configuration of a self-checkout device. The self-checkout device 1 is an example of an article information processing device, and is used, for example, in a store such as a supermarket.

The self-checkout device 1 includes an accounting section 10 and a cash register counter 20. The main body 2 of the accounting department 10 includes a monitor 3 with a touch panel disposed on its surface. As the monitor 3, for example, a liquid crystal display is used.

The main body 2 of the accounting section 10 is provided with a card insertion slot 4 for inserting a customer's membership card or credit card at the time of accounting (settlement), and a receipt issuing slot 5 for issuing a receipt.

The main body 2 also has a bill deposit/withdrawal slot 6 for depositing bills for settlement and receiving change bills, a coin slot 7 for inserting coins at the time of settlement, and a coin slot 7 for receiving change coins. An outlet 8 is provided.

A stand 9 is provided on the upper side of the main body 2, and a handy barcode reader 11 is placed and supported on the stand 9. The mounting table 9 is an example of a mounting section on which the barcode reader 11 is mounted. Note that the placing section does not place the entire barcode reader 11 as in this embodiment, but may support the barcode reader 11 in a removable manner by placing a part of it thereon. good. A weight sensor 12 (see FIG. 2), which is an example of a first detection section that detects the contact state between the mounting table 9 and the barcode reader 11, is provided on the upper surface of the mounting table 9, that is, the surface on which the barcode reader 11 is placed. It is being The weight sensor 12 outputs a detection signal when it detects that the barcode reader 11 has been removed from the stand 9 due to a change in the weight applied to the stand 9. Note that the first detection unit that detects the contact state between the barcode reader 11 and the stand 9 is not limited to the weight sensor 12, and a known sensor such as an optical sensor can be used.

The barcode reader 11 is used while being removed from the stand 9 to read code information of a barcode attached to a product. The barcode reader 11 includes a grip portion 13 that is held by a user. The grip portion 13 has a built-in capacitance sensor 14 (see FIG. 2), which is an example of a second detection portion. The capacitance sensor 14 outputs a detection signal when detecting that the user grips the grip portion 13 . Note that the second detection section that detects that the customer has grasped the grip section 13 is not limited to the capacitance sensor 14, but may be a known sensor such as a pressure sensor.

The checkout counter 20 is divided into a tag information reading area 22 (reading area) and a bagging area 23 by a partition plate 21. The tag information reading area 22 is provided with a placing section 24 on which a shopping cart containing products to be purchased by a customer is placed. An RFID reader 25 (see FIG. 2) is provided below the placement unit 24 to read tag information from a wireless tag attached to a product placed in the tag information reading area 22. In this embodiment, the placement unit 24 is used as a configuration for placing the product in the tag information reading area 22, but the configuration is not limited thereto. For example, a configuration may be adopted in which a shopping cart containing a plurality of products is positioned in the tag information reading area 22 and the tag information of the wireless tag attached to each product is read at once.

Although not shown, the tag information reading area 22 is provided with a start sensor that detects whether a shopping cart or a product is placed on the placing section 24. When a shopping cart or a product is detected by this start sensor, the RFID reader 25 starts reading the tag information of the wireless tag. As the start sensor, various known sensors such as a weight sensor and an optical sensor can be used. Furthermore, it is desirable that the partition plate 21 is made of a radio wave shielding material so that the RFID reader 25 does not read wireless tags located outside the tag information reading area 22.

The bagging area 23 is an area where products whose tag information has been read in the tag information reading area 22 are temporarily placed. The customer can use this bagging area 23 to bag products.

Next, with reference to FIG. 2, the hardware configuration of the self-checkout device 1 will be described. The self-checkout device 1 includes a control section 30, a memory section 40, a controller 50, a communication I/F (Interface) 40, and the like. The control section 30, the memory section 40, the controller 50, and the communication I/F 60 are connected to each other via a bus 61.

The control unit 30 includes a CPU (Central Processing Unit) 31, a ROM (Read Only Memory) 32, and a RAM (Random Access Memory) 33. The CPU 31, ROM 32, and RAM 33 are connected to each other via a bus 61.

The CPU 31 controls the entire operation of the self-checkout device 1. The ROM 32 stores various programs such as programs used to drive the CPU 31 and various data. The RAM 33 is used as a work area for the CPU 31 and expands various programs and data stored in the ROM 32 and the memory unit 40. The control unit 30 executes various control processes for the self-checkout apparatus 1 by causing the CPU 31 to operate according to a control program stored in the ROM 32 or the memory unit 40 and developed in the RAM 33.

The memory section 40 includes a control program section 41 and a product master section 42. The control program section 41 stores a control program for functioning as the self-checkout device 1 and various other control programs. The product master section 42 stores a product master indicating product information. In the product master, a product name, price, etc. are associated with a product code that can identify the type of product. Note that since the products handled at the store change daily, the product master is updated as appropriate from a server (not shown) connected via the communication I/F 60.

Note that the control program executed by the self-checkout device 1 of this embodiment may be configured to be recorded and provided on a computer-readable recording medium such as a CD-ROM. Further, the control program may be configured to be stored on a computer connected to a network such as the Internet and provided by downloading via the network, and further provided or distributed via a network such as the Internet. It may be configured to do so.

The controller 50 is connected to various hardware such as a monitor 3 with a touch panel, a change machine 51, a printer 52, a card reader 53, an RFID reader 25, a barcode reader 11, a weight sensor 12, and a capacitance sensor 14. This allows the control unit 30 to send and receive information to and from the various hardware described above via the controller 50.

The monitor 3 displays operation buttons operated by the customer, various information, etc., and receives various inputs from the customer through a touch panel that detects operations on the displayed operation buttons. The change machine 51 accepts banknotes and coins paid by the customer when the customer pays for the purchase of a product in cash, and dispenses change as necessary. The printer 52 prints a receipt after the customer's payment is completed, and issues the receipt from the receipt issuing port 5. The card reader 53 reads information from a membership card or credit card inserted into the card insertion slot 4.

The communication I/F 60 is connected to the server mentioned above. This allows the server to update the product master.

Next, the functional configuration of the control unit 30 of the self-checkout device 1 will be explained with reference to FIG. 3. The control unit 30 operates by the CPU 31 in accordance with the control program stored in the ROM 32 and the control program unit 41 of the memory unit 40, thereby controlling the product information input unit 301, product registration unit 302, accounting processing unit 303, and sensor information input unit. 304, RFID reading control section 305, and display control section 306. Note that the product information input section 301, product registration section 302, accounting processing section 303, sensor information input section 304, RFID reading control section 305, and display control section 306 may be configured by hardware.

Information related to a product is input to the product information input section 301. Specifically, tag information is input from the RFID reader 25 or code information is input from the barcode reader 11 to the product information input section 301 .

The product registration unit 302 performs product sales registration (product registration) based on the information input to the product information input unit 301. Specifically, the product registration unit 302 obtains product information by comparing the product code included in the tag information and code information with the product code of each product stored in the product master, and registers the obtained product. Product registration is performed by temporarily storing information in the RAM 33 or the like. Product registration by the product registration unit 302 is an example of processing performed by the product information processing device.

The accounting processing unit 303 performs accounting processing for products purchased by the customer based on product information registered by the product registration unit 302. For example, the accounting processing unit 303 calculates the total amount from the price included in the product information of each registered product. Furthermore, the accounting processing unit 303 calculates the amount of change by subtracting the total amount from the amount deposited in the change machine 51, and then controls the change machine 51 to discharge the change. The accounting processing unit 303 also performs other processing necessary for the customer to make payment, such as printing and issuing a receipt. Accounting processing by the accounting processing unit 303 is an example of processing performed by the article information processing device.

The sensor information input unit 304 receives the outputs of the weight sensor 12 and the capacitance sensor 14 . Specifically, when the barcode reader 11 placed on the stand 9 is lifted by the customer, the weight sensor 12 outputs a detection signal, and the output detection signal is input to the sensor information input section 304. . Furthermore, when the customer grasps the grip portion 13 of the barcode reader 11, the capacitance sensor 14 outputs a detection signal, and the output detection signal is input to the sensor information input section 304. The sensor information input unit 304 distinguishes and recognizes the detection signal from the weight sensor 12 and the detection signal from the capacitance sensor 14.

The RFID reading control unit 305 outputs a control signal to the RFID reader 25 to control the RFID reader 25. Specifically, when the start sensor provided in the tag information reading area 22 described above detects a product, the RFID reading control unit 305 causes the RFID reader to start reading the tag information. Further, when the sensor information input unit 304 receives a detection signal output from the weight sensor 12 or the capacitance sensor 14, the RFID reading control unit 305 stops the operation of the RFID reader 25 and stops reading the tag information. .

The display control unit 306 outputs a control signal to the monitor 3 to control the display on the monitor 3. For example, the display control unit 306 causes the monitor 3 to display a list of products registered by the product registration unit 302. Further, the display control unit 306 causes the monitor 3 to display an operation button for instructing the accounting processing unit 303 to perform accounting processing after the customer confirms the displayed products. The display control unit 306 causes the monitor 3 to display other contents necessary for the customer to operate the self-checkout device 1.

The operation of the self-checkout device 1 based on the above configuration will be explained. The self-checkout device 1 of the embodiment suppresses the duplication of product registration of product information based on tag information and product information based on code information for one product. As an example, a process in which the control unit 30 controls the RFID reader 25 based on the detection result of the weight sensor 12 will be described with reference to the flowchart of FIG. 4.

First, the control unit 30 determines whether there is a reading start input (S1), and if there is an input (YES in S1), the control unit 30 determines whether tag information has been input from the RFID reader 25 to the product information input unit 301. (S2). In this embodiment, the reading start input is performed by the start sensor detecting the shopping cart placed on the placing section 24, but the invention is not limited to this.

In S1, if the reading start input is not made (NO in S1), the process of the control unit 30 returns to S1. In S2, when tag information is input to the product information input unit 301 (YES in S2), the product registration unit 302 refers to the product master unit 42 to obtain product information (S3), and applies the information to the obtained product information. Based on this, product registration is performed (S4). After registering the product, the process of the control unit 30 returns to S2.

When the product registration for all the tag information read by the RFID reader 25 is completed and it is determined in S2 that no new tag information has been input to the product information input unit 301, the display control unit 306 displays the information that the product has been registered. A list of products is displayed on the monitor 3 (S5). For example, if all the products that the customer wants to purchase are products that do not have wireless tags attached, there will be no products registered based on the tag information, so in S5, a message indicating that there are no registered products is displayed.

When all the products that the customer wishes to purchase are displayed on the monitor 3, the customer issues a payment instruction from the touch panel. The control unit 30 determines whether an accounting instruction has been input from the touch panel (S6), and if an accounting instruction has been input (YES in S6), the accounting processing unit 303 performs accounting processing (S7), and the control unit 303 performs accounting processing (S7). 30 ends the process.

If there is an input that there are products that have not been registered, such as when no checkout instructions are given and the tag information of the wireless tags attached to some products is not read from the touch panel (NO in S6) , the display control unit 306 displays guidance on the monitor 3 (S8). The content of the guidance is a display prompting the barcode reader 11 to read code information for products for which product registration has not been completed. Additionally, when reading the code information, the display control unit 306 causes the monitor 3 to display operating instructions to remove the barcode reader 11 and then hold the product. Although the details will be described later, by displaying this operating procedure to the customer, it is possible to further prevent duplicate product registrations for the same product.

Subsequently, the control unit 30 determines whether a detection signal is input from the weight sensor 12 to the sensor information input unit 304 (S9). When the detection signal is input to the sensor information input unit 304 (YES in S9), the control unit 30 determines that the barcode reader 11 starts reading the code information, and the RFID reading control unit 305 determines that the barcode reader 11 starts reading the code information. A reading stop instruction is output to 25 (S10). Thereby, the RFID reader 25 stops the reading operation.

In S9, if there is no detection signal input from the weight sensor 12 to the sensor information input unit 304 (NO in S9), the control unit 30 determines whether new tag information that is not registered as a product has been input to the product information input unit 301. It is determined whether or not (S11). Since the tag information also includes individual item information that specifies each product, the control unit 30 can determine whether the read tag information is registered as a product.

If new tag information is input to the product information input unit 301 (YES in S11), the control unit 30 returns to the process in S3, and if no tag information is input to the product information input unit 301 (NO in S11), the control unit 30 returns to the process in S3. It is determined whether a predetermined period of time has elapsed since the accounting instruction was given (S12). If the predetermined time has elapsed (YES in S12), the control unit 30 returns to the process in S5, and if the predetermined time has not elapsed (NO in S12), the control unit 30 returns to the process in S9. Note that when the process returns to S5 after a predetermined period of time has passed since the checkout instruction, the display control unit 306 controls the monitor 3 to switch from the guidance display to the registered product display. At this time, a screen may also be displayed to prompt the customer to make payment instructions.

In S10, after the RFID reading control unit 305 outputs a reading stop instruction to the RFID reader 25, the control unit 30 determines whether code information has been input from the barcode reader 11 to the product information input unit 301 (S13 ). When the code information is input (YES in S13), the product registration unit 302 acquires product information from the product master (S14) and performs product registration (S15).

Subsequently, the control unit 30 determines whether or not there is a reading end input from the touch panel (S16), and if there is an input (YES in S16), the control unit 30 assumes that the reading by the barcode reader 11 has ended and proceeds to the process of S5. If there is no input (NO in S16), the process returns to S13.

In S13, if the code information is not input (NO in S13), the control unit 30 determines whether a predetermined period of time has passed since the code information was last input (S17). Note that if no code information has been input even once since the RFID reader 25 was instructed to stop in S10, it is determined in S17 whether a predetermined period of time has elapsed since the RFID reader 25 was instructed to stop. . If the predetermined time has elapsed in S17 (YES in S17), the control unit 30 determines that the customer has forgotten to input the reading end input, and returns to the process in S5. If the predetermined time has not elapsed in S17 (NO in S17), the control unit 30 returns to the process in S13.

As described above, in the article information processing apparatus of this embodiment, when it is detected that the code reader is removed from the placement section, reading by the wireless tag reader is stopped. That is, when the self-checkout device 1 detects that the barcode reader 11 is no longer in contact with the stand 9, it stops the reading operation of the RFID reader 25. Therefore, it is possible to quickly grasp the situation in which barcode reader 11 can perform reading, and to stop reading by RFID reader 25. Therefore, it is possible to prevent duplicate product registration of tag information and code information related to the same product.

Further, according to the self-checkout device 1 of the present embodiment, for products whose tag information cannot be read by the RFID reader 25, a display is displayed to prompt the customer to read the code information by the barcode reader 11. At this time, an operating procedure to remove the barcode reader 11 and then pick up the product is displayed on the monitor 3 as guidance. Thereby, as described below, it is possible to further suppress tag information and code information related to the same product from being registered twice as a product.

When reading code information with the barcode reader 11, the moment the customer picks up the product and moves it, the overlap between the wireless tag and the metal disappears, and the tag information of the wireless tag attached to the product is transferred to the wireless tag reader. It can be read in. However, if the customer follows the above guidance, the reading operation of the RFID reader 25 can be stopped before the customer moves the product. Therefore, it is possible to further prevent tag information and code information related to the same product from being registered twice as a product.

In the above embodiment, the reading operation of the RFID reader 25 is stopped based on the detection signal from the weight sensor 12, which is the first detection section, but the reading operation of the RFID reader 25 is stopped based on the detection signal from the capacitance sensor 14, which is the second detection section. Based on this, the reading operation of the RFID reader 25 may be stopped. In this case as well, it is possible to quickly grasp the situation in which the barcode reader 11 can perform reading, and stop the reading by the RFID reader 25. Therefore, similarly to the embodiment described above, it is possible to prevent the tag information and code information related to the same product from being registered twice.

In the above embodiment, the code reader is described as the barcode reader 11, but it is also possible to apply a two-dimensional code reader or the like. Further, as a means for prohibiting reading by the RFID reader 25, stopping the reading operation of the RFID reader 25 has been adopted, but the present invention is not limited to this. For example, the output of the RFID reader 25 may be reduced to such an extent that the tag information of the wireless tag present in the tag information reading area 22 cannot be read. Alternatively, a radio wave shielding member that is moved by a drive unit may be provided, and when it is detected that the code reader is removed from the mounting unit, the radio wave shielding member is moved by the drive unit to cover the antenna of the RFID reader 25. good.

(Second embodiment)
Next, a second embodiment will be described. The configuration of the self-checkout device 1 is similar to that of the first embodiment. The difference from the first embodiment is that the control unit 30 does not stop the reading operation of the RFID reader 25 based on the sensor information, but discards the tag information read by the RFID reader 25. Therefore, explanations that overlap with those of the first embodiment will be omitted, and only the different points will be explained.

The processing of the control unit 30 will be described below with reference to the flowchart of FIG. Note that in FIG. 5, the difference from the first embodiment is the processing after the detection signal from the weight sensor 12 is input in S9, so this point will be explained.

In FIG. 5, when a detection signal is input from the weight sensor 12 in S9, that is, when it is detected that the customer has removed the barcode reader 11 from the stand 9, the control unit 30 sends the product information input unit 301 to the product information input unit 301. It is determined whether new tag information that has not been registered as a product has been input from the RFID reader 25 (S20). When new tag information is input (YES in S20), the control unit 30 determines that the tag information of the product whose code information will be read by the barcode reader 11 has been input, and the product registration unit 302 inputs the new tag information. The control unit 30 discards the tag information (S21), and returns to the process of S20.

In S20, if new tag information has not been input (NO in S20), the control unit 30 determines whether code information has been input from the barcode reader 11 to the product information input unit 301 (S23). When the code information is input (YES in S23), the product registration unit 302 acquires product information from the product master (S24) and performs product registration (S25).

Subsequently, the control unit 30 determines whether or not there is a reading end input from the touch panel (S26), and if there is an input (YES in S26), the control unit 30 assumes that the reading by the barcode reader 11 has been completed and proceeds to the process of S5. If there is no input (NO in S20), the process returns to S23.

In S23, if the code information is not input (NO in S23), the control unit 30 determines whether a predetermined period of time has passed since the code information was last input (S27). Note that if the code information has not been input even once since the RFID reader 25 was instructed to stop in S10, it is determined in S27 whether a predetermined period of time has elapsed since the RFID reader 25 was instructed to stop. . If the predetermined time has elapsed in S27 (YES in S27), the control unit 30 determines that the customer has forgotten to input the reading end input, and returns to the process in S5. If the predetermined time has not elapsed in S27 (NO in S27), the control unit 30 returns to the process in S20.

In the second embodiment, when it is detected that the barcode reader 11 has been removed from the placement section, tag information read by the wireless tag reader after that is not processed. That is, when the self-checkout device 1 detects that the barcode reader 11 and the stand 9 are no longer in contact, it discards newly read tag information thereafter. For this reason, the situation where the barcode reader 11 can read the information is quickly grasped, and for products whose code information is read by the barcode reader 11, the tag information read by the RFID reader 25 is not registered as a product. Therefore, similarly to the first embodiment, it is possible to prevent tag information and code information related to the same product from being registered twice.

Note that in this embodiment, after detecting that the barcode reader 11 has been removed from the stand 9, tag information newly read by the RFID reader 25 is discarded so as not to be processed. It is not limited to this. For example, the RFID reader 25 may not output tag information read after detecting that the barcode reader 11 is removed from the stand 9 to the product information input unit 301. In this case as well, the product registration unit 302 does not register the tag information read after detecting that the barcode reader 11 has been removed from the stand 9 and does not process the tag information.

Similar to the first embodiment, in the second embodiment, the detection signal is not based on the detection signal from the weight sensor 12, which is the first detection part, but is based on the detection signal from the capacitance sensor 14, which is the second detection part. Then, the tag information newly read by the product registration unit 302 may be discarded. Furthermore, instead of the barcode reader 11, a two-dimensional code reader or the like may be used as the code reader.

Furthermore, the RFID reading control section 305 can also control the RFID reader 25 based on the output results of both the weight sensor 12, which is the first detection section, and the capacitance sensor 14, which is the second detection section. be. Specifically, when the weight sensor 12 detects that the barcode reader 11 is separated from the stand 9, and the capacitance sensor 14 detects that the user grips the barcode reader 11, Reading by the RFID reader 25 is prohibited. Alternatively, when the above detection is made, the tag information read by the RFID reader 25 thereafter is discarded.

In this way, by employing the output results of both the weight sensor 12 and the capacitance sensor 14, it is possible to quickly detect the state in which the barcode reader 11 can be used more reliably.

The above embodiments are presented as examples and are not intended to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. This embodiment and its modifications are included within the scope and gist of the invention, as well as within the scope of the invention described in the claims and its equivalents.
