DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In all drawings, similar components are given similar reference numerals, and descriptions thereof will be omitted as appropriate. In addition, unless otherwise specified, in each block diagram, each block represents a functional configuration, not a hardware configuration. In addition, when there is an arrow in a drawing, the direction of the arrow is merely intended to clearly indicate the flow of information, and does not limit the direction of communication (one-way / two-way) unless otherwise specified.

[0016] [First embodiment] 1 is a diagram conceptually illustrating the configuration of a reading system according to the present disclosure. The reading system 1 illustrated in FIG.

[0017] <Configuration of the reading device 10> The reading device 10 is a device that performs wireless communication with a medium 30 having a wireless communication function (hereinafter, also referred to as a "wireless communication medium"). Although not particularly limited, the reading device 10 is a portable terminal such as a smartphone or a tablet terminal. The reading device 10 has at least a function of reading information stored in the wireless communication medium 30 from the wireless communication medium 30. The reading device 10 may further have a function of writing any information into a storage area of ​​the wireless communication medium 30. The reading device 10 illustrated in FIG. 1 includes a display 12, a transmitting unit 110, a receiving unit 120, a display processing unit 130, and a communication unit 140.

[0018] The communication unit 140 can perform non-contact wireless communication with the wireless communication medium 30. The communication unit 140 is compatible with various non-contact wireless communication standards such as ISO / IEC 10536, ISO / IEC 14443 (Type-A, Type-B), and ISO / IEC 18092, and performs wireless communication with the wireless communication medium 30. The communication unit 140 is realized by a structure similar to that adopted in a known reading device. In the reading system 1 in the present disclosure, the communication unit 140 (the position where the reading device 10 communicates with the wireless communication medium 30) is provided on a second surface located on the opposite side of the first surface on which the display 12 is provided. Therefore, when wireless communication is performed between the reading device 10 and the wireless communication medium 30, the basic positional relationship between the reading device 10 and the wireless communication medium 30 is as shown in FIG. 2. FIG. 2 is a diagram that illustrates the positional relationship between the reading device 10 and the wireless communication medium 30 when wireless communication is performed between the reading device 10 and the wireless communication medium 30. As shown in FIG. 2, when the reading device 10 and the wireless communication medium 30 are brought close to each other to perform wireless communication, the wireless communication medium 30 is located behind the reading device 10 (display 12) from the user's perspective.

[0019] The transmitting unit 110, the receiving unit 120 and the display processing unit 130 perform processing to enable the user to easily grasp the appropriate positional relationship before wireless communication is performed between the above-mentioned communication unit 140 and the wireless communication medium 30.

[0020] First, the transmission unit 110 acquires model information of the reading device 10 and transmits it to the external server device 20 connected via a network (not shown). The model information is any information capable of identifying the internal structure of the reading device. Although not particularly limited, the model information may be, for example, information indicating the model or model of the reading device, such as the model name, model number, or model number. Such model information is stored in advance in a predetermined storage area, such as the memory or storage device of the reading device 10. Here, if the position of the communication unit 140 differs depending on the model or model of the reading device 10, the position suitable for wireless communication with the wireless communication medium 30 also differs depending on the position of the communication unit 140. The model information acquired by the transmission unit 110 is used in the server device 20 to identify a position where stable communication can be performed between the reading device 10 and the wireless communication medium 30.

[0021] The receiving unit 120 receives guide information determined in the server device 20 based on the model information transmitted from the transmitting unit 110. Here, the guide information is information for displaying on the display 12 the position of the wireless communication medium 30 relative to the reading device 10 when wireless communication is performed between the reading device 10 and the wireless communication medium 30. A specific example of this guide information will be described later.

[0022] The display processing unit 130 displays on the display 12 display elements based on the guide information received by the receiving unit 120. Here, as shown in FIG. 2, when the wireless communication medium 30 and the reading device 10 are brought close to each other to perform wireless communication, the reading device 10 (display 12) is located between the wireless communication medium 30 and the user. As a result, at least a part of the wireless communication medium 30 is not visible to the user. However, in this embodiment, the display 12 displays display elements indicating the position of the wireless communication medium 30 relative to the reading device 10 during wireless communication, according to the guide information determined based on the model information. Therefore, the user can place the reading device 10 and the wireless communication medium 30 in appropriate positions for wireless communication by simply adjusting the positional relationship between the reading device 10 and the wireless communication medium 30 according to the display elements displayed on the display 12. By setting the reading device 10 and the wireless communication medium 30 in an appropriate positional relationship, stable wireless communication between the reading device 10 and the wireless communication medium 30 is possible.

[0023] Each functional component of the reading device 10 may be realized by hardware that realizes each functional component (e.g., a hardwired electronic circuit, etc.), or may be realized by a combination of hardware and software (e.g., a combination of an electronic circuit and a program that controls it, etc.). The following further describes the case where each functional component of the reading device 10 is realized by a combination of hardware and software.

[0024] 3 is a block diagram illustrating a hardware configuration of the reading device 10. In the example of FIG. 3, the reading device 10 includes a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input / output interface 1050, and a network interface 1060.

[0025] The bus 1010 is a data transmission path for transmitting and receiving data between the hardware components. However, the method for connecting the hardware components of the reading device 10 is not limited to a bus connection.

[0026] The processor 1020 is implemented by a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or the like.

[0027] The memory 1030 is a main storage device realized by a RAM (Random Access Memory) or the like.

[0028] The storage device 1040 is an auxiliary storage device realized by a hard disk drive (HDD), a solid state drive (SSD), a memory card, a read only memory (ROM), or the like. The storage device 1040 stores program modules that realize each function of the reading device 10 (such as the transmitting unit 110, the receiving unit 120, the display processing unit 130, and the communication unit 140). The processor 1020 loads these program modules onto the memory 1030 and executes them, thereby realizing each function corresponding to each program module on the reading device 10.

[0029] The input / output interface 1050 is an interface for connecting the reading device 10 to various input / output devices. In the example of FIG. 3, the display 12 is connected to the input / output interface 1050. The display 12 is an LCD (Liquid Crystal Display) or an OEL (Organic Electro Luminescence) display. The display 12 connected to the input / output interface 1050 may be a touch panel display equipped with a touch panel. In addition, an input / output device other than the display 12 may be connected to the input / output interface 1050.

[0030] The network interface 1060 is an interface for connecting the reading device 10 to a network. The network interface 1060 connects the reading device 10 to the network by wire or wirelessly. This network is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). The reading device 10 can communicate with other devices on the network via the network interface 1060 to transmit and receive various data. For example, the reading device 10 can transmit model information to the server device 20 and receive guide information from the server device 20 via the network interface 1060. As shown in the figure, a wireless communication module 1062 is connected to the network interface 1060. The wireless communication module 1062 is compatible with various NFC standards, and data is exchanged between the reader 10 and the wireless communication medium 30 via an antenna (not shown).

[0031] 3 is merely an example, and the hardware configuration of the reading device 10 in the present disclosure is not limited to the example shown in FIG.

[0032] <Configuration of the server device 20> The server device 20 has a function of providing guide information to the reading device 10. The server device 20 illustrated in FIG.

[0033] The acquisition unit 210 acquires the model information transmitted from the reading device 10 as described above. The guide information transmission unit 220 acquires guide information based on the model information acquired by the acquisition unit 210. In the example of FIG. 1, the guide information transmission unit 220 refers to a guide information database 40 that stores guide information by model, and acquires guide information corresponding to the model information acquired from the reading device 10 from the guide information database 40. The guide information database 40 may be provided in the server device 20, or may be provided in another external device communicably connected to the server device 20. As described above, the guide information indicates the position of the wireless communication medium 30 with respect to the reading device 10 during wireless communication. Then, the guide information transmission unit 220 transmits the guide information acquired based on the model information from the reading device 10 to the reading device 10.

[0034] Each functional component of the server device 20 may be realized by hardware that realizes each functional component (e.g., a hardwired electronic circuit, etc.), or may be realized by a combination of hardware and software (e.g., a combination of an electronic circuit and a program that controls it, etc.). Below, a further description will be given of the case where each functional component of the server device 20 is realized by a combination of hardware and software.

[0035] 4 is a block diagram illustrating an example of a hardware configuration of the server device 20. In the example of FIG. 4, the server device 20 includes a bus 2010, a processor 2020, a memory 2030, a storage device 2040, an input / output interface 2050, and a network interface 2060.

[0036] The bus 2010 is a data transmission path for transmitting and receiving data between the hardware components, but the method for connecting the hardware components of the server device 20 is not limited to bus connection.

[0037] The processor 2020 is implemented by a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or the like.

[0038] The memory 2030 is a main storage device realized by a RAM (Random Access Memory) or the like.

[0039] The storage device 2040 is an auxiliary storage device realized by a hard disk drive (HDD), a solid state drive (SSD), a memory card, a read only memory (ROM), or the like. The storage device 2040 stores program modules that realize each function of the server device 20 (the acquisition unit 210, the guide information transmission unit 220, etc.). The processor 2020 loads and executes each of these program modules onto the memory 2030, thereby realizing each function corresponding to each program module on the server device 20.

[0040] The input / output interface 2050 is an interface for connecting the server device 20 to various input / output devices. To the input / output interface 2050, various input / output devices such as a keyboard, a mouse, a display, and a speaker can be connected.

[0041] The network interface 2060 is an interface for connecting the server device 20 to a network. The network interface 20 connects the server device 20 to the network by wire or wirelessly. This network is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). The server device 20 can communicate with other devices on the network via the network interface 2060 to transmit and receive various data. For example, the server device 20 can acquire model information from the reading device 10 via the network interface 2060, and can transmit guide information determined based on the model information to the reading device 10. In addition, when the above-mentioned guide information database 40 is provided in an external device (not shown) on the network, the server device 20 can access the guide information database 40 of the external device via the network interface 2060 and acquire guide information corresponding to the model information acquired from the reading device 10.

[0042] 4 is merely an example, and the hardware configuration of the server device 20 in the present disclosure is not limited to the example shown in FIG.

[0043] <Processing flow> The process executed by the reading device 10 and the server device 20 will be described with reference to Fig. 5. Fig. 5 is a sequence diagram illustrating the flow of the process executed by the reading device 10 and the server device 20 of the first embodiment.

[0044] First, a trigger operation for starting wireless communication with the wireless communication medium 30 is executed on the reading device 10 side (S102). For example, a user executes an operation of pressing a button on the display 12 of the reading device 10 as a trigger for starting wireless communication. In response to this operation, the transmission unit 110 acquires model information of the reading device 10 stored in a predetermined storage area such as the memory 1030 or the storage device 1040 (S104). Then, the transmission unit 110 transmits the model information of the reading device 10 acquired in the process of S104 to the server device 20 (S106).

[0045] The server device 20 receives the model information transmitted from the reading device 10 in the process of S106 at the acquisition unit 210. When the acquisition unit 210 acquires the model information of the reading device 10, the guide information transmission unit 220 determines guide information based on the model information (S108). For example, the guide information transmission unit 220 refers to the guide information database 40 (e.g., FIG. 6) and acquires guide information corresponding to the model information acquired from the reading device 10 from the guide information database 40. FIG. 6 is a diagram showing an example of information stored in the guide information database 40 of the first embodiment. In the example of FIG. 6, the guide information database 40 stores guide information classified by model information. For example, when the model information transmitted in the process of S106 indicates "model A", the guide information transmission unit 220 can determine "guide information A" associated with "model A" in the guide information database 40 as the guide information to be transmitted to the reading device 10. Then, the guide information transmitting unit 220 transmits the guide information acquired in S108 to the reading device 10 (S110).

[0046] The receiving unit 120 acquires the guide information determined in the server device 20 based on the model information transmitted in the process of S106. When the receiving unit 120 acquires the guide information, the display processing unit 130 displays a display element based on the guide information on the display 12 (S112). For example, the display processing unit 130 displays a display element as exemplified in FIG. 7 on the display 12. FIG. 7 is a diagram showing an example of a display element based on the guide information. The display element G1 based on the guide information as exemplified in FIG. 7 indicates the position of at least a part of the edge of the wireless communication medium 30 when the wireless communication medium 30 is placed at the communication position of the reading device 10. Note that the guide information is determined in the server device 20 according to the model information, and therefore may vary according to the model of the reading device 10. For example, for a reading device 10 of a model different from that of the reading device 10 of FIG. 7, a display element based on the guide information as exemplified in FIG. 8 may be displayed on the display 12. FIG. 8 is a diagram showing another example of a display element based on the guide information. In the example of FIG. 8, a display element G2 based on guide information in which the arrangement of the edge of the wireless communication medium 30 is different from the display element G1 based on the guide information of FIG. To Such a difference in the arrangement of the wireless communication medium 30 relative to the reading device 10 occurs due to a difference in the internal structure of the reading device 10.

[0047] Then, the user adjusts the positional relationship between the reading device 10 and the wireless communication medium 30 according to the guide information displayed on the display 12. For example, when the display element G1 based on the guide information illustrated in FIG. 7 is displayed on the display 12, the user adjusts the positional relationship between the reading device 10 and the wireless communication medium 30 as shown in FIG. 9. FIG. 9 is a diagram illustrating an example of adjusting the positional relationship between the reading device 10 and the wireless communication medium 30 according to the display element G1 based on the guide information illustrated in FIG. 7. As illustrated, the wireless communication medium 30 is placed at the communication position of the reading device 10 according to the display element G1 based on the guide information, whereby wireless communication is performed between the reading device 10 and the wireless communication medium 30 (S114).

[0048] In this embodiment, guide information is determined according to the model of the reading device 10 that communicates with the wireless communication medium 30, and based on the guide information, a display element indicating an appropriate positional relationship between the reading device 10 and the wireless communication medium 30 is displayed on the display 12. The display element based on the guide information allows the user to easily adjust the positional relationship between the reading device 10 and the wireless communication medium 30 so that stable wireless communication is performed between the reading device 10 and the wireless communication medium 30.

[0049] <Modification> In this modified example, the display processing unit 130 is configured to, for example, cause the display 12 to further display information indicating the remaining time until the communication is completed while the medium 30 is placed at the communication position of the reading device 10.

[0050] Here, the time required to complete communication with the wireless communication medium 30 may vary depending on model-specific information such as the specifications of the reading device 10. The specifications of the reading device 10 can be determined, for example, using model information. In this modification, the display processing unit 130 uses the model information of the reading device 10 to specify a communication time corresponding to the model information. Note that the communication time corresponding to the model of the reading device 10 can be determined, for example, based on the results of actually performing reading and writing using various wireless communication media 30. In addition, the communication time corresponding to the model of the reading device 10 may use a theoretical value based on the specifications of the reading device 10. The communication time corresponding to the model of the reading device 10 obtained in this manner is, for example, stored in a database in association with the model information of the reading device 10. In this case, the display processing unit 130 can obtain the communication time corresponding to the model information of the reading device 10 from the database.

[0051] The display processing unit 130 can visualize the time until the communication is completed according to the model information of the reading device 10, for example, as shown in FIG. 10, and present it to the user. FIG. 10 is a diagram showing an example of information indicating the time until the communication is completed. In the example of FIG. 10, the display processing unit 130 further displays, on the display 12, a status bar SB indicating the current progress with respect to the time until the communication is completed according to the model information. Note that, in the example of FIG. 10, the display processing unit 130 can start a timer, for example, when wireless communication with the medium 30 is started in the communication unit 140 as a trigger, and update the display on the status bar SB according to the elapsed time of the timer. For example, the display processing unit 130 can update the display on the status bar SB (display of the shaded area indicating the progress) based on the ratio of the elapsed time of the timer to the time until the communication is completed, etc.

[0052] In the configuration of this modified example, information indicating the remaining time until the wireless communication between the reading device 10 and the wireless communication medium 30 is completed is further displayed on the display 12. Such information allows the user to easily grasp that the wireless communication between the reading device 10 and the wireless communication medium 30 is being performed without any problems and the progress of the wireless communication.

[0053] [Second embodiment] This embodiment is similar to the first embodiment except for the points described below. For example, the reading system 1 of this embodiment has the same functional configuration (e.g., FIG. 1) as the reading system 1 of the first embodiment except for the points described below.

[0054] <Configuration of the reading device 10> In this embodiment, the transmission unit 110 acquires medium type information in addition to the model information described in the first embodiment. The medium type information is information that indicates the type of medium. Then, the transmission unit 110 transmits the model information and the medium type information to the server device 20.

[0055] Here, the internal structure (e.g., antenna position) of the wireless communication medium 30 may differ depending on the type of the wireless communication medium 30. For example, the antenna position may differ between a transportation IC card (one type of wireless communication medium 30) issued by a certain transportation facility and an electronic money card (another type of wireless communication medium 30) issued by a certain retail company. If the type of medium is identified by the medium type information, it is possible to identify the internal structure unique to each type of wireless communication medium 30, such as the antenna position in the wireless communication medium 30 of that type. Then, based on the internal structure (e.g., antenna position) of the wireless communication medium 30 identifiable by the medium type information and the internal structure (e.g., antenna position) of the reading device 10 identifiable by the model information of the reading device 10, it is possible to more accurately specify the position where stable communication can be performed between the reading device 10 and the wireless communication medium 30. In this embodiment, based on this idea, corresponding guide information is prepared for each combination of model information and medium type information.

[0056] The receiving unit 120 receives guide information from the server device 20, similarly to the first embodiment. Note that in this embodiment, the guide information is determined in the server device 20 based on a combination of model information and medium type information.

[0057] Then, the display processing unit 130 displays on the display 12 display elements based on the guide information acquired from the server device 20 as response information to the combination of the model information and the medium type information.

[0058] <Configuration of the server device 20> As described above, the acquisition unit 210 of this embodiment acquires model information and medium type information from the reading device 10. The guide information transmission unit 220 acquires corresponding guide information from the guide information database 40 based on the combination of the model information and medium type information acquired by the acquisition unit 210. Then, the guide information transmission unit 220 transmits the guide information based on the combination of the model information and medium type information to the reading device 10.

[0059] <Processing flow> The process executed by the reading device 10 and the server device 20 will be described with reference to Fig. 11. Fig. 11 is a sequence diagram illustrating the flow of the process executed by the reading device 10 and the server device 20 of the second embodiment.

[0060] First, a trigger operation for starting wireless communication with the medium 30 is executed on the side of the reading device 10 (S202). For example, the user executes an operation of pressing a button on the display 12 of the reading device 10 as a trigger for starting wireless communication. In response to these operations, the transmission unit 110 acquires model information of the reading device 10 stored in a predetermined storage area such as the memory 1030 or the storage device 1040 (S204). At this time, the transmission unit 110 further acquires medium type information indicating the type of wireless communication medium 30. For example, the reading device 10 displays a list of types of wireless communication medium 30 that can be used on the display 12, and accepts a selection input operation for the list. The transmission unit 110 acquires information indicating the type of wireless communication medium 30 specified by this operation as medium type information. In addition, when the type of wireless communication medium 30 used in the service is predetermined, medium type information indicating the type may be stored in advance in a storage area of ​​the reading device 10. In this case, the transmission unit 110 can obtain the model information and the medium type information from a predetermined storage area in response to the trigger operation. Then, the transmission unit 110 transmits the model information of the reading device 10 obtained in the process of S204 and the medium type information obtained in the process of S206 to the server device 20 (S208).

[0061] The server device 20 receives the model information and the medium type information of the wireless communication medium 30 transmitted from the reading device 10 in the process of S208 at the acquisition unit 210. When the acquisition unit 210 acquires the model information of the reading device 10 and the medium type information of the wireless communication medium 30, the guide information transmission unit 220 determines guide information based on the model information and the medium type information (S210). For example, the guide information transmission unit 220 refers to the guide information database 40 (e.g., FIG. 12) and acquires guide information corresponding to the model information acquired from the reading device 10 from the guide information database 40. FIG. 12 is a diagram showing an example of information stored in the guide information database 40 of the second embodiment. In the example of FIG. 12, the guide information database 40 stores guide information classified by the combination of the model information and the medium type information. Note that even if the types of the wireless communication medium 30 are different, the internal structure (e.g., the position of the antenna) may be approximately the same. In such a case, even if the combinations of the model information and the medium type information are different, the corresponding guide information may be the same. In the example of Fig. 12, "medium c" and "medium d" correspond to this case. For example, when the model information and medium type information transmitted in the process of S208 indicate "model A" and "medium c (or medium d)", respectively, the guide information transmitting unit 220 can determine "guide information A-3" associated with the combination of "model A" and "medium c (or medium d)" in the guide information database 40 as the guide information to be transmitted to the reading device 10. Then, the guide information transmitting unit 220 transmits the guide information thus acquired in S210 to the reading device 10 (S212).

[0062] The receiving unit 120 acquires the guide information determined in the server device 20 based on the combination of the model information and the medium type information transmitted in the process of S208. When the receiving unit 120 acquires the guide information, the display processing unit 130 displays a display element based on the guide information on the display 12 (S214).

[0063] As an example, the display processing unit 130 displays a display element indicating the position of at least a part of the edge of the wireless communication medium 30 on the display 12, as exemplified in Fig. 7 and Fig. 8. In this embodiment, the display element exemplified in Fig. 7 and Fig. 8 is determined based on a combination of the model information and the medium type information.

[0064] In this embodiment, unlike the first embodiment, medium type information is further acquired. By utilizing this medium type information, it is possible to show the user an appropriate position of the wireless communication medium relative to the reading device 10 during wireless communication.

[0065] For example, the display element based on the guide information may show the appearance of the area of ​​the wireless communication medium 30 that overlaps with the display 12 when the wireless communication medium 30 is placed at the communication position of the reading device 10. The display element in this case is, for example, information as exemplified in FIG. 13. FIG. 13 is a diagram showing an example of a display element based on the guide information that can be output in the second embodiment. In the example of FIG. 13, a display element G3 based on the guide information is displayed on the display 12. The display element G3 based on the guide information shows the appearance of the area of ​​the wireless communication medium 30 that overlaps with the display 12 (i.e., the area of ​​the wireless communication medium 30 that is hidden by the display 12). The guide information database 40 stores guide information as exemplified in FIG. 13 for each combination of model information and medium type information. For example, the guide information database 40 may store, as guide information, a partial image trimmed from the entire image of the wireless communication medium 30 in accordance with the screen size of each model, and display position information of the partial image on the display 12. In this case, the display processing unit 130 can display guide information as exemplified in FIG. 13 by outputting the partial image acquired from the server device 20 to a position on the display 12 indicated by the display position information also acquired from the server device 20. The guide information database 40 may store an entire image of the wireless communication medium 30 instead of a partial image. In this case, the display processing unit 130 may be configured to generate a partial image by trimming the entire image of the wireless communication medium 30 acquired from the server device 20. The display processing unit 130 may display only the area where the display 12 and the wireless communication medium 30 overlap on the display 12 by adjusting the display position of the entire image of the wireless communication medium 30 based on the display position information acquired from the server device 20 without trimming.

[0066] As another example, the display element based on the guide information may indicate the position of the reference information of the medium 30 when the medium 30 is placed at the communication position of the reading device 10. The reference information is information that serves as a landmark on the surface of the medium 30. The reference information may be appropriately determined from among information included in the area of ​​the medium 30 that overlaps with the display 12 when the medium 30 is placed at the communication position of the reading device 10. Although not particularly limited, it is preferable from the viewpoint of usability that the reference information is a distinctive design on the surface of the medium 30, such as an ID photo, a predetermined character string, or a logo. As a specific example, for example, guide information as shown in FIG. 14 is displayed on the display 12. FIG. 14 is a diagram showing another example of a display element based on the guide information that can be output in the second embodiment. In the example of FIG. 14, a display element G4 based on the guide information indicating the position of an ID photo on the surface of the wireless communication medium 30 is displayed on the display 12.

[0067] The display elements based on the guide information displayed on the display 12 may be a combination of the above-mentioned specific examples. For example, the display elements based on the guide information may show the position of at least a part of the edge of the wireless communication medium 30 when the wireless communication medium 30 is placed at the communication position of the reading device 10, and the appearance of the area of ​​the wireless communication medium 30 that overlaps with the display 12 when the wireless communication medium 30 is placed at the communication position of the reading device 10. ,example For example, the display element based on the guide information may indicate the position of at least a part of the edge of the wireless communication medium 30 when the wireless communication medium 30 is placed at the communication position of the reading device 10, and the position of the reference information of the wireless communication medium 30 when the wireless communication medium 30 is placed at the communication position of the reading device 10. Furthermore, the display element based on the guide information is not limited to the example shown in the figure, and any information can be used as long as it indicates an appropriate positional relationship between the reading device 10 and the wireless communication medium 30.

[0068] Then, the user adjusts the positional relationship between the reading device 10 and the wireless communication medium 30 according to the display element based on the guide information displayed on the display 12. For example, when the display element G3 based on the guide information illustrated in FIG. 13 is displayed on the display 12, the user adjusts the positional relationship between the reading device 10 and the wireless communication medium 30 as shown in FIG. 15. FIG. 15 is a diagram illustrating an example of adjusting the positional relationship between the reading device 10 and the wireless communication medium 30 according to the display element G3 based on the guide information illustrated in FIG. 13. As illustrated, the wireless communication medium 30 is placed at the communication position of the reading device 10 according to the display element G3 based on the guide information, whereby wireless communication is performed between the reading device 10 and the wireless communication medium 30 (S216).

[0069] In addition, considering that the positional relationship between the reading device 10 and the wireless communication medium 30 during wireless communication is as depicted in Fig. 2, display elements as exemplified in Fig. 13 are preferable. For example, as shown in Fig. 15, an easy-to-understand user interface is provided in which the wireless communication medium 30 can be seen through, so that it can be said that the user can easily visually grasp the appropriate positional relationship between the reading device 10 and the wireless communication medium 30.

[0070] In this embodiment, a display element showing an appropriate positional relationship between the reading device 10 and the wireless communication medium 30 is displayed on the display 12 based on guide information determined according to a combination of the model of the reading device 10 that communicates with the wireless communication medium 30 and the type of the wireless communication medium 30. The display element based on this guide information allows the user to easily adjust the positional relationship between the reading device 10 and the wireless communication medium 30 so that stable wireless communication is performed between the reading device 10 and the wireless communication medium 30. In addition, by using the medium type information, the internal structure of the wireless communication medium 30 (such as the position of the antenna) can be further taken into consideration, so that a position where stable communication can be performed between the reading device 10 and the wireless communication medium 30 can be more accurately specified compared to the first embodiment.

[0071] <Modification> In this embodiment as well, the display processing unit 130 may be configured to, for example, cause the display 12 to further display information indicating the remaining time until the communication is completed while the medium 30 is placed at the communication position of the reading device 10. This modification is different from the modification of the first embodiment in the following description.

[0072] As described in the modified example of the first embodiment, the time required to complete communication with the wireless communication medium 30 may vary depending on model-specific information such as the specifications of the reading device 10. In addition, the time required for wireless communication may vary depending on the structure of the wireless communication medium 30 and the information to be read or written. In this embodiment, unlike the first embodiment, medium type information indicating the type of the wireless communication medium 30 is further acquired, so that it is possible to specify the time required for wireless communication taking into account the "type of the wireless communication medium 30."

[0073] For example, the display processing unit 130 of this modified example can obtain the time required for the communication with the wireless communication medium 30 to be completed with higher accuracy based on the combination of the model information and the medium type information. The communication time according to the combination of the model of the reading device 10 and the type of the wireless communication medium 30 can be determined based on the result of actually executing reading and writing for each combination of the model of the reading device 10 and the type of the wireless communication medium 30. In addition, the communication time according to the combination of the model of the reading device 10 and the type of the wireless communication medium 30 may be a theoretical value based on the specifications of the reading device 10 and the average data communication fee of the wireless communication medium 30. The communication time according to the combination of the model of the reading device 10 and the type of the wireless communication medium 30 obtained in this way is made into a database in association with, for example, the model information of the reading device 10. In this case, the display processing unit 130 can obtain the corresponding communication time from the database. Then, the display processing unit 130 can display information indicating the remaining time until the wireless communication is completed, for example, as illustrated in FIG. 10, based on the communication time obtained according to the combination and the elapsed time of a timer that is activated according to the start of wireless communication with the wireless communication medium 30.

[0074] [Third embodiment] This embodiment is similar to the second embodiment except for the points described below. For example, the reading system 1 of this embodiment has the same functional configuration (e.g., FIG. 1) as the reading system 1 of the second embodiment except for the points described below.

[0075] <Configuration of the server device 20> The acquiring unit 210 of this embodiment acquires model information and medium type information from the reading device 10, similarly to the second embodiment. The guide information transmitting unit 220 acquires corresponding guide information from the guide information database 40 based on the combination of the model information and medium type information acquired by the acquiring unit 210. Then, the guide information transmitting unit 220 transmits guide information based on the combination of the model information and medium type information to the reading device 10. Here, the guide information in this embodiment includes information indicating changes over time in the display magnification and display position of an image showing the appearance of the wireless communication medium.

[0076] <Configuration of the reading device 10> In this embodiment, the receiving unit 120 acquires guide information including information indicating changes over time in the display magnification and display position of an image showing the appearance of the wireless communication medium as response information to the combination of the model information and medium type information transmitted to the server device 20. Based on such guide information, the display processing unit 130 of this embodiment is able to display display elements that are easy for the user to understand regarding the operation of placing the wireless communication medium in the communication position of the reading device 10.

[0077] <Display Example by Display Processing Unit 130> FIG. 16 is a diagram showing an example of a display element based on guide information output by the display processing unit 130 according to the third embodiment.

[0078] First, the display processing unit 130 of the present embodiment detects the medium type of the wireless communication medium. kindAn image showing the overall appearance of the wireless communication medium (hereinafter, also referred to as a "medium appearance image") specified based on the information is obtained (e.g., FIG. 16(a)). The medium appearance image showing the overall appearance of the wireless communication medium may be included in the guide information transmitted from the server device 20, or may be included in the medium type corresponding to the storage device 1040 of the reading device 10. kind The information may be stored in advance in association with the information.

[0079] The display processing unit 130 displays the medium appearance image on the display 12 of the reading device 10 at a display magnification and display position that allow the user to visually confirm the overall appearance of the wireless communication medium used for wireless communication, as shown in Fig. 16. The initial display magnification and initial display position (position coordinates) of the medium appearance image are determined, for example, based on the model information and the medium type. kind The information is defined in the guide information acquired as response information to the combination with the information. By displaying the medium appearance image in such a way that the entire image can be seen, the user can easily understand the type of wireless communication medium to be used for wireless communication.

[0080] Then, the display processing unit 130 changes the display state of the medium appearance image on the display 12 according to information included in the guide information, which indicates changes over time in the display magnification and display position of the medium appearance image. For example, as shown in Fig. 16(b) to (e), the display processing unit 130 uses animation to express the state in which the wireless communication medium is moved to the reading position of the reading device 10, based on the information indicating changes over time in the display magnification and display position.

[0081] In addition, when the medium appearance image has information of a three-dimensional appearance model, the display processing unit 130 can express the rotation of the medium appearance image by animation (for example, FIGS. 17(a) to 17(c)). j17 is a diagram showing another example of a display element based on guide information output by the display processing unit 130 according to the third embodiment. By expressing three-dimensional movements in animation as shown in FIG. 17, the user can easily understand how to hold the wireless communication medium over the reading device 10 when making the reading device 10 read the wireless communication medium.

[0082] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention should not be interpreted as being limited thereto, and various modifications, improvements, etc. can be made based on the knowledge of a person skilled in the art without departing from the gist of the present invention. In addition, the multiple components disclosed in the embodiments can be appropriately combined to form various inventions. For example, some components may be deleted from all the components shown in the embodiments, or components of different embodiments may be appropriately combined.

[0083] For example, in the above embodiment, an example has been described in which a database (guide information database 40) that stores guide information for each model information or for each combination of model information and medium type information is provided on the server device 20 side, but such a database may be constructed in the reading device 10. For example, when installing an application that runs on the reading device 10, a database that stores guide information for each model information or for each combination of model information and medium type information may be constructed in a storage area of ​​the reading device 10. In this case, the reading device 10 can execute the process up to displaying the guide information by itself.

[0084] In addition, in the flowcharts used in the above description, multiple steps (processes) are described in order, but the order of execution of the steps performed in each embodiment is not limited to the order described. In each embodiment, the order of the steps shown in the figures can be changed to the extent that the content is not affected.
