  As described above, in this type of conventional information transmission terminal device, each time the information stored in the product tag of the product brought close to the reading surface of the tag reading unit is read, data communication with the server is performed for the product. Since the detailed product information to be provided to the consumer is read and displayed on the display unit, the product information that the shopper wants to refer to the detailed information is brought close to the reading surface of the tag reading unit, and the detailed information of the product is displayed on the display unit. There was a waiting time required for communication until it was displayed on the screen, and many shoppers felt that this waiting time was inconvenient.

  The present invention has been made based on such circumstances. The purpose of the present invention is to make the tag reader read the information stored in the product tag of the product for which the shopper wants to refer to the detailed information, and then the product. It is intended to provide an information transmission terminal device that can shorten the time required for the detailed information to be displayed and output on the display unit, so that the shopper cannot feel inconvenience.

  The information transmission terminal device of the present invention is connected to a server having a data file in which detailed product information to be provided to consumers regarding each product is stored through a communication line. In addition, a tag reading unit that reads the information stored in the memory of the product tag attached to each product using wireless communication without contact, and the product tag is attached based on the information read from the product tag without contact Product specifying means for specifying the product being sold and product detailed information display means for displaying the product detailed information are provided. In addition, a storage unit capable of storing product detailed information read from a server via a communication line, a request receiving unit for receiving a request for referring to product detailed information, and a request for referring to product detailed information by the request receiving unit Reading range switching means for setting the tag reading range of the tag reading unit to a wide range in the vicinity of the tag reading unit until the tag is received, and setting a narrow range close to the reading surface of the tag reading unit after receiving the reference request. And control means. In a state where the tag reading range of the tag reading unit is set to a wide range by the reading range switching unit, the control unit reads the product detailed information of the product specified by the product specifying unit from the server and stores it in the storage unit. In the state set to the range, the detailed product information of the product specified by the product specifying unit is read from the storage unit and displayed on the product information display unit.

  By taking such means, when the shopper who wants to refer to the detailed information of the desired product for purchase approaches the information transmission terminal device according to the present invention, the tag reading range of the tag reading unit at this point is near the tag reading unit. Since it is set in a wide range, the tag reading unit reads information on the product tag attached to each of one or more products possessed by the shopper. Then, the detailed information of each product is read from the server and accumulated and stored in the storage unit. After that, when the shopper makes a request for referring to the detailed product information to the information transmission terminal device, and subsequently brings the product for which detailed information is to be referred to close to the reading surface of the tag reading unit, the tag reading unit responds to the reference request. Since the tag reading range is switched to a narrow range close to the reading surface, only the information of the product tag attached to the product is read by the tag reading unit. At this time, since the detailed information of the product is already stored in the storage unit, it is immediately read out from the storage unit and displayed on the display unit.

  Therefore, according to the information transmission terminal device of the present invention, the information stored in the product tag of the product for which the shopper wants to refer to the detailed information is read by the tag reading unit, and then the detailed information of the product is displayed on the display unit. The time it takes to be done can be reduced to the point where the shopper feels inconvenient. As a result, the information transmission terminal device can be made convenient for the shopper and the customer service can be improved.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic diagram showing an embodiment of a store system including an information transmission terminal device 1 according to the present invention. The store system of this embodiment includes an information transmission terminal device 1, a POS terminal device 2, and a store server 3. Usually, the information transmission terminal device 1 is installed in a product display (sales) of a store such as a supermarket where the store system is constructed. The POS terminal device 2 is installed in an accounting area (cash register) of the store. The store server 3 is installed in a management office of the store. The information transmission terminal device 1, the POS terminal device 2, and the store server 3 are connected to each other through a LAN (Local Area Network) 4 that is one mode of a communication line so that they can communicate with each other.

  The store server 3 is provided with a product master file 5 in which various information regarding various products A, B, C,... The main items of information for one product set in the product master file 5 are shown in the schematic diagram of FIG. As shown in the figure, the product master file 5 associates one product with a product code unique to the product, classification code (department, group, etc.), sales floor code, product name, unit price, tax classification (external tax, Internal tax, tax exemption, etc.), cost, production area (place name, prefecture name, etc.), producer (person name, agricultural cooperative name, association name, etc.), production date, expiration date, content type (raw material name, additive, quantity) Etc.), various components such as nutritional components (such as calories) and product images are set.

  Incidentally, the item “expiration date” is the last day of the period in which the information is valid information. For example, in the case of information on products with expiration dates such as fresh food such as meat, fresh fish, and vegetables, they will not be sold at least after the last date of the expiration date, so the last date of this expiration date will be the effective date of the information. .

  Further, a response identification flag F is added to each item data of the product information stored in the product master file 5. The response identification flag F is an item that responds only to a product information inquiry from the POS terminal device 2 for an item that responds to a product information inquiry from both the information transmission terminal device 1 and the POS terminal device 2. Is "2" for items that respond only to product information queries from the information transmission terminal device 1, and "0" for items that do not respond to any product information queries. Is set.

  The product master file 5 is not necessarily stored in the store server 3, but is stored on another server connected via an external network 6 such as the Internet, for example, a server at the headquarters that manages the store. Also good.

  The information transmission terminal device 1 has a tag reading unit that can read information stored in a memory of a product tag 7 attached to each of various products A, B, C,. 8 is provided. The product tag 7 is a small electronic component generally referred to as an RFID, a product tag, a transponder, or the like. In this embodiment, a battery-less type that employs a radio wave system as a communication system is used. The principal part structure of the product tag 7 and the tag reading part 8 is shown with the block diagram of FIG.

  The product tag 7 is obtained by providing a loop-shaped tag antenna 71 and an IC chip 72 on a sheet-like tag member that can be attached to a product. The IC chip 72 rectifies and stabilizes the modulated radio wave received by the tag antenna 71 to demodulate the modulated radio wave and send it to the control unit 724. Modulation unit 723 that modulates data sent from the demodulation unit 722 and control unit 724 and sends the data to the tag antenna 71, writes data demodulated by the demodulation unit 722 to the memory 725, and reads and modulates data from the memory 725 A control unit 724 for sending to the unit 723 and a non-volatile memory 725 are included. The memory 725 includes an ID area for storing a unique ID assigned and set by the manufacturer at the manufacturing stage of the product tag 7 and a user area where the user can write arbitrary data. In the user area, a product code unique to the product to which the product tag 7 is attached is stored.

  The tag reading unit 8 includes an antenna unit 81 that forms a reading surface and a reader unit 82. The reader unit 82 includes a control unit 821 that controls transmission of a tag reading signal, an interface unit 822 that controls data communication between the control unit 821 and the information transmission terminal device 1, and a tag reading signal that is supplied from the control unit 821. Is modulated into a modulation signal suitable for wireless communication, a transmission amplifier 824 that amplifies the modulation signal and radiates it as a linearly polarized wave from the antenna unit 81, and radiates from the antenna unit 81 under the control of the control unit 821. Output intensity switching section 825 that switches the output intensity of the radio wave to be received, reception amplifier 826 that amplifies the radio signal received by antenna unit 81, and demodulation that demodulates the tag response signal from the amplified radio signal and gives it to control section 821 Part 827.

  When the “strong” mode is set by the control of the control unit 821, the output intensity switching unit 825 is configured so that the radio wave transmitted from the antenna unit 81 reaches a wide range with a radius of about 30 cm to 100 cm around the antenna unit 81. In addition, when the “weak” mode is set, the radio wave communication distance is switched so that only a narrow range of about 5 cm can reach from the antenna unit 81.

  With this configuration, the product tag 7 that has received the tag read signal radio wave radiated from the antenna unit 81 of the tag reading unit 8 by the tag antenna 71 is activated, and the ID and product code information stored in the memory 725 is stored. The signal is transmitted from the tag antenna 71 as a modulated radio wave. The modulated radio wave transmitted from the tag antenna 71 of the product tag 7 is received by the antenna unit 81 of the tag reading unit 8, amplified, demodulated into a tag response signal including an ID and a product code, and given to the information transmission terminal device 1. It is done.

  Therefore, when the output intensity switching unit 825 is set to the “strong” mode, the product tag 7 located within the vicinity of the radius 30 cm to 100 cm around the antenna unit 81 is activated, and the product tag 7 The product code stored in the memory 725 is read and given to the information transmission terminal device 1. Further, when the output intensity switching unit 825 is set to the “weak” mode, the product tag 7 that is brought close to about 5 cm from the antenna unit 81 is activated and stored in the memory 725 of the product tag 7. The product code is read and given to the information transmission terminal device 1.

  The principal part structure of the information transmission terminal device 1 is shown with the block diagram of FIG. As shown in the figure, the information transmission terminal device 1 includes a CPU (Central Processing Unit) 11 constituting control means, a ROM (Read Only Memory) 12 in which fixed data such as programs are stored in advance, and various data can be rewritten. RAM (Random Access Memory) 13 to be stored, HDD (Hard Disk Drive) device 14 which is a non-volatile storage means, a clock unit 15 constituted by an IC chip for measuring the current date and time, data communication performed via the LAN 4 The LAN interface 16 that controls the tag, the interface 17 with the tag reading unit 8, the keyboard controller 19 that detects key input of the keyboard 18, the touch panel controller 21 that controls the screen display of the touch panel 20 and detects the touch input, and the printer 22 printing The printer controller 23 and the like for controlling the operation are included. The CPU 11, ROM 12, RAM 13, HDD device 14, clock unit 15, LAN interface 16, tag reading unit interface 17 and controllers 19, 21, 23 of various input / output devices are connected via a bus line 24 such as an address bus and a data bus. It is connected.

  The HDD device 14 is provided with a detailed information file 9 (see FIG. 1) having a smaller capacity than the product master file 5. The main items of information for one product stored in the detailed information file 9 are shown in the schematic diagram of FIG. As shown in the figure, in the detailed information file 9, “1” or “1” is set as the response identification flag F in the product information set in the product master file 5 in association with the product code unique to the product for one product. Items such as a product code, a product name, a production location, a producer, a production date, an expiration date, a content type, a nutritional component, and a product image are stored. These item information is detailed product information to be provided to consumers. Here, the detailed information file 9 functions as a storage unit capable of storing a plurality of, for example, about 1000 to 10,000 pieces of product detailed information.

Accordingly, the CPU 11 controls the information transmission processing of the information transmission terminal device 1 in accordance with the procedure shown in the flowchart of FIG.
First, the CPU 11 displays an initial screen on the touch panel 20 as ST (step) 1. As shown in FIG. 8, the initial screen is a screen on which an operation guidance 31 for a shopper who wants to refer to detailed product information and a reference button 32 that can be touch-operated are displayed.

  Next, the CPU 11 commands the output radio field intensity “strong” to the tag reading unit 8 connected to the tag reading unit interface 17 as ST2. Next, in ST3, the tag reading unit 8 is instructed to transmit a tag reading radio wave.

  As a result, the control unit 821 of the tag reading unit 8 sets the operation mode of the output intensity switching unit 825 to “strong”, and then gives the tag reading signal to the modulation unit 823. Thus, a modulated radio wave of the tag reading signal is transmitted from the antenna unit 81 of the tag reading unit 8 with an intensity reaching a wide range of a radius of about 30 cm to 100 cm around the antenna unit 81. At this time, if even one product tag 7 exists within the communication distance range of the modulated radio wave, the product code stored in the memory 725 of the product tag 7 is read by the tag reading unit 8 in a non-contact manner, and the information transmission terminal It is given to the device 1.

  Therefore, the CPU 11 waits for the product code to be read by the tag reading unit 8 as ST4 after issuing the tag reading radio wave transmission command. If the product code is not input to the tag reading unit interface 17 even after a predetermined time has elapsed, the product code has not been read, so the processing returns to ST3 and the tag reading radio wave is transmitted again to the tag reading unit 8. Is commanded.

  When a product code is input to the tag reading unit interface 17 within a fixed time after the tag reading radio wave transmission command is issued, the CPU 11 searches the detailed information file 9 for ST5 and searches for detailed product information of the product code. As a result, when the detailed product information of the product code is detected from the detailed information file 9 as ST6, the CPU 11 determines the expiration date of the detailed product information and the current date counted by the clock unit 15 as ST7. Are compared to determine whether the product detail information has expired. If it is determined that the expiration date of the product detailed information is the same date as the current date or a future date and the expiration date is not expired, the process proceeds to ST11.

  On the other hand, when the detailed product information of the product code cannot be detected from the detailed information file 9 at ST6, or when it is determined at ST7 that the expiration date is earlier than the current date and has expired. In step ST8, the CPU 11 transmits a command for inquiring product detail information of the product code to the store server 3 via the LAN 4.

  In the store server 3 that has received this inquiry command, the inquiry reception process shown in the flowchart of FIG. 7 is executed. That is, when the store server 3 confirms that the received command is a product detail information inquiry command from the information transmission terminal device 1, the store server 3 searches the product master file 5 using the product code in the command. Then, if the product information stored in association with the product code is detected from the product master file 5, the information of the item for which the response identification code = “1” or “3” is set from the product information. The information of the extracted item is extracted and transmitted to the inquiry source information transmission terminal device 1 via the LAN 4 as the detailed product information.

  Then, CPU11 of the information transmission terminal device 1 which transmitted the detailed information inquiry command waits for the response of goods detailed information as ST9. When receiving the response of the product detail information from the store server 3 via the LAN 4, the CPU 11 adds the product detail information responded as ST 10 to the detailed information file 9. At this time, if the number of records in the detailed information file 9 is full or near full, search for expired information and delete the expired information at once (information organizing means) After freeing up space, add it. If there is no expired information, the data with the oldest storage time is deleted and secured after free space is added. Thereafter, the CPU 11 proceeds to the process of ST11.

  In ST11, the CPU 11 determines whether or not the reference button 32 on the initial screen displayed on the touch panel 20 has been touched. When the touch operation is not performed, the CPU 11 returns to the process of ST3 and instructs the tag reading unit 8 to transmit the tag reading radio wave again.

  If the CPU 11 detects that the reference button 32 has been touched by a signal input to the touch panel controller 21, the CPU 11 instructs the tag reader 8 to set the output radio wave intensity “weak” as ST12. In ST13, the screen of the touch panel 20 is switched from the initial screen to the product reading screen. As shown in FIG. 9, the merchandise switching screen is a screen on which operation guidance 41 for instructing the shopper to bring merchandise with reference to detailed information closer to the reading surface of the tag reading unit 8 is displayed.

  Next, the CPU 11 instructs the tag reading unit 8 to transmit a tag reading radio wave in ST14.

  Thereby, the control unit 821 of the tag reading unit 8 switches the operation mode of the output intensity switching unit 825 to “weak”, and then gives the tag reading signal to the modulation unit 823. Thus, the modulated radio wave of the tag reading signal is transmitted from the antenna unit 81 of the tag reading unit 8 with an intensity that can reach only a narrow range of about 5 cm from the surface (reading surface) of the antenna unit 81. In this state, when the product tag 7 attached to the product brought close to the surface of the antenna unit 81 enters the communication distance of the modulated radio wave, the product code stored in the memory 725 of the product tag 7 is the tag reading unit. 8 is read in a non-contact manner and provided to the information transmission terminal device 1.

  Therefore, the CPU 11 waits for the product code to be read by the tag reading unit 8 as ST15 after issuing the tag reading radio wave transmission command. If the product code is not input to the tag reading unit interface 17 even after a certain period of time has elapsed, the product code has not been read, so the process returns to ST14 and the tag reading radio wave is transmitted to the tag reading unit 8 again. Is commanded.

  When a product code is input to the tag reading unit interface 17 within a certain time after the tag reading radio wave transmission command is issued, the CPU 11 searches the detailed information file 9 for ST16 and searches for detailed product information of the product code. As a result, when the product detail information of the product code is detected from the detailed information file 9 as ST17, the CPU 11 proceeds to the process of ST21.

  On the other hand, when the product detail information of the product code cannot be detected from the detailed information file 9 in ST17, the CPU 11 inquires the store server 3 of the product detail information of the product code via the LAN 4 in ST18. Send a command.

  Also in this case, the store server 3 executes the inquiry reception process shown in the flowchart of FIG.

  Then, CPU11 waits for the response of goods detailed information from the store server 3 as ST19. Then, when receiving the response of the product detail information from the store server 3 via the LAN 4, the CPU 11 adds the product detail information responded as ST20 to the detailed information file 9. Also in this case, when the number of records in the detailed information file 9 is the full number or the near full number, search for the expired information, delete the expired information at once, secure the free space, and add it. . Thereafter, the CPU 11 proceeds to the process of ST21.

  In ST21, the CPU 11 reads out the detailed product information of the product code from the detailed information file 9. Then, the screen of the touch panel 20 is switched from the product reading screen to the product detailed information screen, and the product detailed information of the product code is displayed. As shown in FIG. 10, the product detail information screen is a screen on which product detail information 51 of the product code, another product button 52 that can be touch-operated, and an end button 53 are displayed.

  In this state, the CPU 11 waits for another product button 52 on the product detail information screen displayed on the touch panel 20 as ST22 to be touch-operated, or for ST23 to be touched by the end button 53 on the same screen as ST23. To do. When the CPU 11 detects that another product button 52 has been touched by a signal input to the touch panel controller 21, the CPU 11 returns the screen of the touch panel 20 from the product detail information screen to the product reading screen. On the other hand, when it is detected that the end button 53 has been touched, the CPU 11 ends the current information transmission process. Then, the screen of the touch panel 20 is returned from the product detail information screen to the initial screen.

  Here, the information transmission terminal device 1 has a product specifying means for specifying the product to which the product tag is attached from the product code read from the product tag 7 by the tag reading unit 8. Further, the request accepting means is configured by the function of displaying the reference button 32 that can be touch-operated on the initial screen. Further, the reading range switching means is constituted by the processes of ST2 and ST12 of the information transmission process executed by the CPU 11, and the control means is constituted by the processes of ST5 to ST10, ST16 and ST21.

  In the present embodiment configured as described above, in a steady state, from the antenna unit 81 of the tag reading unit 8 connected to the information transmitting terminal device 1, a wide range with a radius of about 30 cm to 100 cm is set as a communication range. Strongly modulated radio waves are periodically transmitted. Therefore, when the shopper approaches the information transmission terminal device 1, the product tag 7 attached to one or more products stored in the shopping basket held by the customer or the cart pushed by the customer is activated. The product codes stored in the memory 725 of each product tag 7 are sequentially read by the tag reading unit 8 in a non-contact manner. Thereby, in the information transmission terminal device 1, every time the product code of the product tag 7 is read by the tag reading unit 8, whether or not the product detailed information associated with the product code is stored in the detailed information file 9. To be judged. If it is not stored, the store server 3 is inquired about the product detail information, and the product detail information set in the product master file 5 is read into the information transmission terminal device 1 via the LAN 4. The detailed information file 9 is additionally stored.

  Here, when there is a product for which detailed information such as a production place is to be confirmed among the products put in the shopping basket or the cart by the shopper, the shopper stands in front of the touch panel 20 of the information transmission terminal device 1. . At this time, since the initial screen shown in FIG. 8 is displayed on the touch panel 20, the shopper touches the reference button 32.

  Then, the screen of the touch panel 20 is switched to a product reading screen having the contents shown in FIG. The modulated radio wave periodically transmitted from the antenna unit 81 of the tag reading unit 8 is a weak radio wave that reaches only about 5 cm from the reading surface, which is the surface of the antenna unit 81. As a result, the product tag 7 of each product that has been activated until then is no longer activated and the product code cannot be read.

  Here, according to the guidance 41 displayed on the touch panel 20, the shopper brings the product tag 7 attached to the product for which detailed information is to be referred close to the reading surface of the tag reading unit 8. Then, only the product tag 7 attached to the product is activated again, and the product code stored in the memory 725 of the product tag 7 is read by the tag reading unit 8 in a non-contact manner. Thereby, in the information transmission terminal device 1, it is determined whether or not the detailed product information associated with the product code is stored in the detailed information file 9. Usually, since the product detailed information is stored in the detailed information file 9 when the shopper approaches the information transmission terminal device 1, the product detailed information is read from the detailed information file 9 and is shown in FIG. As shown, it is displayed on the product detail information screen displayed on the touch panel 20.

  Therefore, the shopper can know the detailed information such as the production location, producer, production date, content type, and nutritional component of the desired product from the content of the product detail information 51 displayed on the product detail information screen. . In this case, since the product detailed information 51 is read from the store server 3 in advance and stored in the detailed information file 9, the information stored in the product tag 7 of the product for which the shopper wants to refer to the detailed information is read as a tag. There is almost no waiting time until the detailed information of the product is displayed on the touch panel 20 after being read by the unit 8. Therefore, since the shopper does not feel the information transmission terminal device 1 inconveniently and actively uses it, the customer service can be improved.

  The shopper who has confirmed the detailed product information 51 on the screen of the touch panel 20 touches the separate product button 52 or the end button 53 in accordance with the display on this screen. That is, a shopper who wants to refer to other product detailed information touches another product button 52. As a result, the screen of the touch panel 20 returns to the product reading screen shown in FIG. 9, and the shopper brings the product tag 7 of the product for which detailed information is to be referred to close to the reading surface. As a result, the detailed information of the product is read from the detailed information file 9 and immediately displayed on the touch panel 20.

  On the other hand, a shopper who does not have any other products for which detailed information is to be referred to touches the end button 53. Then, the screen of the touch panel 20 returns to the initial screen shown in FIG. At this time, the modulated radio wave transmitted from the antenna unit 81 becomes a strong radio wave that reaches a wide range with a radius of about 30 cm to 100 cm around it.

  By the way, since the modulated radio wave is periodically transmitted over a wide range from the antenna unit 81 in the steady state, the store server 3 also reads the detailed information of the product held by the shopper who has just walked near the information transmission terminal device 1. And stored in the detailed information file 9. Therefore, in this embodiment, every time the product code of the product tag 7 is read, it is determined whether or not the detailed information of the product code is stored in the detailed information file 9. Then, only when the information is not stored or when the information is stored but the expiration date of the information has expired, it communicates with the store server 3 to read the corresponding product detailed information and add it to the detailed information file 9 I have to. Therefore, once the detailed product information read from the store server 3 is stored in the detailed information file 9 until its expiration date is expired and is not read again, the product information close to the reading surface of the tag reading unit is stored. There is also an effect that the amount of communication traffic can be reduced as compared with the conventional case where data communication with the server is performed each time the information stored in the product tag is read.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the above-described embodiment, the request accepting unit has been described as the reference button 32 which is a touch button. However, for example, one of the keys provided on the keyboard 18 is set as a reference key, and the reference key is operated. If a product is detected, a reference request for product detail information may be received. Similarly, the separate product button 52 and the end button 53 may be fixed keys of the keyboard 18. In this case, a display other than the touch panel 20 can be used as the display unit.

  In the above embodiment, the product detail information is only displayed and output on the display unit (touch panel 20). For example, if a print button is displayed on the product detail information screen and the print button is touched, The product detail information may be printed out on the recording paper by the printer 22.
