Preferred embodiments of the present invention will be described below with reference to the drawings.
(1) Overview of non-contact type functional system The non-contact type functional system of the present embodiment normally performs non-contact communication (wireless communication) with a device that is compatible with a non-contact type IC card or a similar medium. This is a system configured to be able to realize the specific function realized by the wireless communication between the wristwatch and the corresponding device. Examples of the medium similar to the non-contact type IC card include an IC tag, a medium in which the IC tag is incorporated (for example, a mobile phone), an automobile electronic key, and the like.

  There are various types of specific functions realized by the non-contact function system. Here, first, some specific functions that can be realized by the non-contact type functional system are exemplified. Examples of the specific function include a traffic card function, an electronic money function, a point card function, an electronic lock function, and an automobile electronic key function.

(1-1) Overview of Specific Functions Among various specific functions, an overview of four types of functions, namely, a traffic card function, an electronic money function, an electronic lock function, and an automobile electronic key function will be described. Note that the content of each specific function itself is a conventionally known content.

  The transportation card function is a function used in an automatic ticket gate system that is widely used in transportation such as trains and buses. In the automatic ticket gate system, the user can pass the ticket gate and hold the necessary payment automatically by holding the IC card over the automatic ticket gate.

  In the automatic ticket gate system, a request signal is periodically transmitted from an antenna mounted on a control device in the automatic ticket gate. When the IC card is held near the antenna, the request signal is received by the IC card. When receiving the request signal, the IC card transmits a response signal as a response thereto. This response signal also includes ID information of the IC card. When the response signal transmitted from the IC card is received by the control device in the automatic ticket checker, the control device collates the ID, and if it is a regular ID, further proceeds with necessary processing. The necessary processing includes, for example, acquisition of a user name, acquisition and update of a charge amount, acquisition of a regular use section, acquisition and update of a use history, and the like.

  The IC card stores at least a unique ID. Various information such as the user name, charge amount, periodical usage section, and usage history may be stored in the IC card, or may be held by the system side (for example, a server), or may be stored in the IC card and the server. Both may hold. Hereinafter, the information stored in the IC card including at least the ID is also referred to as card information.

  Wireless communication between the IC card and the control device in the automatic ticket checker is performed by a specific first wireless communication method. The communication frequency (center frequency) is f1. The IC card that can be used in the automatic ticket gate system is generally issued by a transportation company. For example, an “A Electric Railway Card”, which is an IC card that can use a railway network operated by A Electric Railway, is provided to the user from A Electric Railway. Further, for example, a “B subway card” which is an IC card that can use a subway operated by the B City Transportation Bureau is provided to the user from the B City Transportation Bureau.

  In the present embodiment, the card information stored in various types of transportation IC cards as described above can be registered in the wristwatch. The wristwatch can be used as an IC card. That is, by holding the wristwatch over the automatic ticket gate, wireless communication is performed between the control device in the automatic ticket gate and the wristwatch, exactly the same as when holding the IC card, the same as when holding the IC card. You can enjoy the service. Specifically, by passing a wristwatch, it is possible to pass through a ticket gate and automatically complete a payment.

  The electronic money function is a function used in an electronic payment system installed in various stores such as department stores, restaurants, and retail stores. In an electronic payment system, a user can complete a payment without using cash by using an electronic money card which is a kind of IC card.

  In an electronic payment system, a request signal is periodically transmitted from an antenna mounted on a control device for electronic payment. When an electronic money card is held near the antenna, a request signal is received by the electronic money card. When receiving the request signal, the electronic money card transmits a response signal as a response thereto. This response signal also includes ID information of the electronic money card. When the response signal transmitted from the electronic money card is received by the control device, the control device collates the ID. If the response signal is a valid ID, the control device further proceeds with necessary processing. The necessary processing includes, for example, acquisition of a user name, acquisition and update of a charge amount, acquisition and update of a usage history, and the like.

  The electronic money card stores at least a unique ID as card information. Various information such as the user name, the charge amount, and the usage history may be stored in the electronic money card, may be held by the system side (for example, a server), or both the electronic money card and the server You may hold.

  Wireless communication between the electronic money card and the electronic payment control device is performed by the first wireless communication method, as in the case of the traffic card. The communication frequency (center frequency) is the same f1 as that of the traffic card. An electronic money card usable in the electronic payment system is issued from, for example, a specific electronic payment management organization.

  In the present embodiment, card information stored in the electronic money card can be registered in the wristwatch. The wristwatch can be used as an electronic money card. In other words, by holding the wristwatch over the antenna of the electronic payment control device, wireless communication is performed between the control device and the wristwatch just like holding an electronic money card, and the electronic money card is held up. You can enjoy the same service as in the case. Specifically, payment can be completed automatically by holding a wristwatch. You can also charge the watch by holding the watch.

  The electronic lock function is a function used mainly in an electronic lock system introduced inside and outside a building. In an electronic lock system, a user can unlock an entrance of a house, a door of a room in a building, and the like without inserting a physical key and performing an unlocking operation by using an IC card.

  In the electronic lock system, a request signal is periodically transmitted from an antenna mounted on a control device that controls the lock mechanism. When the IC card is held near the antenna, the request signal is received by the IC card. When receiving the request signal, the IC card transmits a response signal as a response thereto. This response signal also includes ID information of the IC card. When the response signal transmitted from the IC card is received by the control device, the control device collates the ID. If the response signal is a regular ID, the control device further proceeds with necessary processing. The necessary processing includes, for example, acquisition of a user name, unlocking processing of a lock mechanism, acquisition and update of a room entry history, and the like.

  The IC card stores at least a unique ID as card information. Various information such as the user name and entry history may be stored in the IC card, may be held by the system side (for example, a server), or may be held by both the IC card and the server. Good.

  Wireless communication between the IC card and the control device is performed by the second wireless communication method. The communication frequency (center frequency) is f2. In a building or the like in which an electronic lock system is introduced, by using a corresponding IC card, both improvement in security performance and improvement in user convenience are realized. For example, in W Co., Ltd., only a person who has a W company entrance card, which is an IC card for unlocking the company entrance gate, can pass through the company entrance gate using the W company entrance card. . Also, for example, at a user's home, only a person who has a home card key that is an IC card for unlocking the entrance of the house can open the entrance using the home card key. .

  In the present embodiment, card information of an IC card used in the electronic lock system can be registered in the wristwatch. The wristwatch can be used as an IC card for an electronic lock system. In other words, by holding the wristwatch over the antenna of the control device of the electronic lock system, wireless communication is performed between the control device and the wristwatch just like holding an IC card, and when holding the IC card. Similarly, it can be unlocked.

  The electronic key function for automobiles is for automobiles that allow users to lock / unlock doors and start / stop engines without touching the keys by wireless communication between the electronic key carried by the user and the automobile. This is a function used in the electronic key system.

  In an automobile electronic key system, request signals are periodically transmitted from an outside-vehicle transmitter and an in-vehicle transmitter mounted on the vehicle. When the electronic key enters the detection area of the request signal and the electronic key receives the request signal, the electronic key transmits a response signal. This response signal includes ID information of the electronic key. When the response signal transmitted from the electronic key is received by the receiver in the vehicle, the control device in the vehicle collates the ID, and if it is a regular ID, further proceeds with necessary processing. The necessary processing includes, for example, processing for shifting to an unlock standby state where the door can be unlocked. For example, when the electronic key is present in the passenger compartment, there is a process of shifting to a start standby state where the engine can be started.

  Wireless communication between the electronic key and the vehicle control device is performed by a specific wireless communication method. Hereinafter, a wireless communication method between the electronic key and the vehicle control device is also referred to as a “smart communication method”. The communication frequency (center frequency) of the smart communication method is f3.

  In the present embodiment, information on the electronic key used in the automobile electronic key system can be registered in the wristwatch. The electronic key information is an ID in the present embodiment, and is information corresponding to the card information. Then, the wristwatch can be used as an electronic key for an automobile electronic key system. In other words, by wearing the wristwatch and approaching the automobile, the automobile can be shifted to the unlock standby state and the door can be opened. In addition, by wearing the wristwatch and getting into the vehicle, the vehicle can be shifted to the start standby state and the engine can be started.

(1-2) Utilization Form of Non-Contact Function System Next, utilization forms of the non-contact function system using the wristwatch 3 of the present embodiment will be described with reference to FIGS.

  In order to use the specific functions using the wristwatch 3, the specific functions need to be registered in the wristwatch 3. In the present embodiment, first, application software (hereinafter abbreviated as “application”) corresponding to a specific function to be registered is installed in the wristwatch 3. Then, the application is started and initial registration of a specific function is performed. By this initial registration, card information of the IC card corresponding to the specific function is registered (stored) in the wristwatch 3. Therefore, after completion of the initial registration, the specific function can be used using the wristwatch 3 in the same manner as the IC card.

  In this embodiment, there are mainly three methods for registering information on the IC card in the wristwatch 3. Both are executed by an application corresponding to a specific function to be registered (hereinafter also referred to as “functional module”).

  In the wristwatch 3, various programs including functional modules are executed by the CPU in the control unit 10 (see FIG. 4). The CPU that executes the various programs is simply referred to as a program name in the following description. It may be described in. For example, the description “functional module” may mean “the CPU executing the functional module”.

  The first registration method is a method in which the wristwatch 3 receives (intercepts) and registers a signal transmitted and received between the IC card and the corresponding device when wireless communication is performed. The second registration method is a method in which the wristwatch 3 directly transmits a request signal corresponding to a specific function to the IC card, and receives and registers a response signal transmitted from the IC card in response to the request signal. The third registration method is to read the card information from the IC card using the relay registration machine 37 (see FIG. 3C), and to read the read card information and the signal transmitted from the corresponding device. This is a method of acquiring and registering from the relay registration device 37 wirelessly. Hereinafter, these three registration methods will be described in detail.

  First, the first registration method will be specifically described. As described above, when the IC card is held over a corresponding device, a response signal is transmitted from the IC card in response to the request signal from the IC card. After the response signal is transmitted, various signals are transmitted and received as necessary. Therefore, the wristwatch 3 is made to receive various signals transmitted and received between the two parties, and the specific function is registered by associating the transmission signal from the corresponding device with the transmission signal from the IC card. Thereby, the function module (application) knows what signal should be transmitted when it receives what signal from the corresponding device. By performing registration in this way, the functional module can behave as a corresponding IC card thereafter.

  Based on FIG. 1, a case where the traffic card function is registered in the wristwatch 3 will be described more specifically as an example. FIG. 1A shows a state in which a user wearing a wrist watch 3 on the arm 2 is holding the IC card 4 and is approaching the A Electric Railway automatic ticket gate 6. In this example, the IC card 4 is an A electric railway card. The automatic ticket gate 6 is equipped with a control device 7 for controlling the opening / closing operation of the gate by the gate mechanism 8. Note that the wireless system used in the traffic card function is the first wireless communication system with a communication frequency of f1. Therefore, the wireless communication method used in the wireless communication performed when registering the traffic card function is also the first wireless communication method.

  As shown in FIG. 1B, the control device 7 includes a reader / writer 7a for performing direct wireless communication with the IC card 4 therein. The antenna 7b of the reader / writer 7a is arranged on the surface of the main body of the automatic ticket gate 6 as shown in FIG. The control device 7 is connected to the server 9 via a network, and performs data communication with the server 9 as necessary.

  In the wristwatch 3, an A electric railway function module, which is a function module (application) necessary for registering an A electric railway system card function, is installed by the user. In addition, various aspects can be considered as to when and how each functional module corresponding to each specific function including the A Electric Railway functional module is installed in the wristwatch 3. For example, various function modules may be preinstalled when the wristwatch 3 is manufactured.

  As shown in FIG. 1A, when the user wearing the wristwatch 3 holds the IC card 4 over the antenna 7b of the automatic ticket gate 6, a request signal RQ periodically transmitted from the antenna 7b is transmitted to the IC card 4. Received at. When receiving the request signal RQ, the IC card 4 transmits a response signal RS in response thereto. The response signal RS includes at least ID 1a which is unique ID information possessed by the IC card 4.

  Both the request signal RQ transmitted from the antenna 7b and the response signal RS transmitted from the IC card 4 to the request signal RQ can be received by the wristwatch 3 as long as the wristwatch 3 is within the communication range of the both. is there. When the request signal RQ and the response signal RS transmitted / received by the communication between the two are sequentially received by the wristwatch 3, the electric train function module in the wristwatch 3 sequentially acquires the received signals. Even after the IC card 4 transmits the response signal RS, signals are transmitted and received as necessary. Each time the received signal is received by the wristwatch 3, the received signal is transmitted to the A Electric Railway functional module. To be acquired.

  While signals are transmitted and received between the control device 7 and the IC card 4, the control device 7 also communicates with the server 9 as necessary. For example, the ID 1 a acquired from the IC card 4 may be transmitted to the server 9 for authentication, and the result may be acquired from the server 9. The ID authentication may be performed by the control device 7. That is, it is possible to appropriately determine how much of the various processes necessary for realizing the traffic card function is handled by the control device 7 and to what extent the server 9 is responsible. The same applies to other specific devices.

  When a predetermined signal is transmitted and received between the control device 7 and the IC card 4 and the ID authentication is successful, the control device 7 controls the gate mechanism 8 to open the gate (not shown), and the user Is allowed to pass.

  On the other hand, when the A electric railway functional module in the wristwatch 3 acquires all the predetermined signals necessary for registration, the A electric railway is stored in the memory 18 (see FIG. 4 to be described later) in association with the ID 1a. Initially register the transportation card function.

  As a result, thereafter, the A electric railway functional module in the wristwatch 3 has the same function as the A electric railway card. After the A electric railway functional module is initially registered, the automatic ticket gate 6 can be passed by the wristwatch 3 alone without using the IC card 4. That is, as shown in FIG. 2 (a), when the user wearing the watch 3 holds the watch 3 over the antenna 7b of the automatic ticket gate 6, as shown in FIG. 2 (b), the period starts from the antenna 7b. The request signal RQ that is transmitted automatically is received by the wristwatch 3, and the response signal RS is transmitted from the wristwatch 3 in response thereto. Thereafter, signals are transmitted and received as necessary in the same manner as in the case of the IC card 4, so that the user can pass through the automatic ticket gate 6.

  Next, the second registration method will be specifically described with reference to FIGS. 3A and 3B, taking the electronic lock function as an example. FIG. 3A shows a state where the user is trying to release the lock to open the front door 31 at home. The entrance door 31 is mechanically locked by a lock mechanism 33. The operation of locking / unlocking by the lock mechanism 33 is controlled by the control device 32. As with the control device 7 in the automatic ticket gate 6 shown in FIG. 1, the control device 32 is provided with a reader / writer and an antenna for performing wireless communication directly with a communication target (in this example, a home card key). ing. The control device 32 is also connected to a server via a network, and performs data communication with the server as necessary.

  A user who is permitted to unlock the front door 31 is usually given a home card key 35 (see FIG. 3B, a type of IC card). When the user holds the home card key 35 close to the antenna installation site in the control device 32, predetermined communication is performed between the control device 32 and the home card key 35. In this communication, as in the case of the traffic card function, the home card key 35 receives the request signal RQ periodically transmitted from the control device 32, and the home card key 35 receives the response signal RS. Includes sending. When a predetermined unlocking condition is established such that the ID is genuine, the control device 32 controls the lock mechanism 33 to unlock the entrance door 31.

  In order to register such an electronic lock function corresponding to the front door 31 in the wristwatch 3 using the second registration method, first, the home key function corresponding to the electronic lock function of the front door 31 is set in the wristwatch 3. Install the module. Then, when the user brings the wristwatch 3 close to the home card key 35 (the communication area of the second wireless communication system by the wristwatch 3), activates the home key function module, and starts the initial registration process. The registration process begins. Specifically, as shown in FIG. 3B, a request signal RQ is first transmitted from the wristwatch 3. This request signal RQ is the same as the request signal RQ periodically transmitted by the control device 32 beside the front door 31. Upon receiving the request signal RQ from the wristwatch 3, the home card key 35 transmits a response signal RS. The response signal RS includes at least ID2b, which is unique ID information possessed by the home card key 35.

  When the response signal RS is received by the wristwatch 3, the home key function module in the wristwatch 3 acquires the response signal RS. Even after receiving the response signal RS, the home key function module of the wristwatch 3 is exactly the same as the communication performed by the control device 32 with the home card key 35 (that is, acts as the control device 32 in a pseudo manner). Necessary data communication is performed, and information necessary for registration is acquired from the home card key 35. The wireless method used in the electronic lock function is the second wireless communication method with a communication frequency of f2. Therefore, the wireless communication method used in wireless communication performed when registering the electronic lock function is also the second wireless communication method.

  When the home key function module in the wristwatch 3 acquires all the predetermined signals necessary for registration, the home key function module stores the signals in the memory 18 (see FIG. 4 described later) in association with the ID 2b, thereby allowing the entrance door 31 to store the signals. Initially register the corresponding electronic lock function.

  Thereby, the home key function module in the wristwatch 3 has functions equivalent to the home card key 35 thereafter. After the home key function module is initially registered, the entrance door 31 can be unlocked only by the wristwatch 3 without using the home card key 35. That is, as shown in FIG. 3A, when the user wearing the wristwatch 3 holds the wristwatch 3 near the antenna installation site in the control device 32, the request signal RQ periodically transmitted from the control device 32 is transmitted. It is received by the wristwatch 3 and a response signal RS is transmitted from the wristwatch 3 in response thereto. Thereafter, as necessary, signals are transmitted and received between the wristwatch 3 and the control device 32 in the same manner as in the case of the home card key 35, whereby the entrance door 31 is unlocked.

  Next, the third registration method will be described in detail with reference to FIGS. 3A and 3C, taking the electronic lock function as an example. In order to register the electronic lock function corresponding to the front door 31 in the wristwatch 3 using the third registration method, the home key function module is installed in the wristwatch 3 as a premise as in the case of the second registration method. Need to be. Further, in order to register by the third registration method, a separate relay registration device 37 is required as shown in FIG.

  In order to register by the third registration method, first, as a first step, necessary information is acquired from the home card key 35 using the relay registration device 37. Specifically, the relay registration device 37 is operated in the pseudo control device mode. In the pseudo control device mode, the relay registration device 37 operates as a control device 32 on the home card key 35 in a pseudo manner. When viewed from the home card key 35, the relay registration device 37 appears as if it is the control device 32, and performs the same operation as the signal transmission / reception to the control device 32. When the relay registration device 37 operates in the pseudo control device mode, the relay registration device 37 can acquire various information necessary for registration including the ID 2b from the home card key 35.

  When the relay registration device 37 acquires necessary information from the home card key 35 in the first step, all information necessary for registration is transmitted from the relay registration device 37 to the wristwatch 3 as a second step. Specifically, first, the user brings the wristwatch 3 in the vicinity of the relay registration device 37 (the communication area of the second wireless communication method) to activate the home key function module, and the initial registration according to the third registration method. Start the registration operation. Then, the relay registration device 37 transmits all information necessary for registration. The information transmitted from the relay registration device 37 includes a request signal RQ and a response signal RS (including ID2b) acquired from the home card key 35. That is, all signals transmitted and received between the home card key 35 and the control device 32 are transmitted from the relay registration device 37 to the wristwatch 3.

  When the home key function module in the wristwatch 3 acquires all the predetermined signals necessary for registration, the home key function module stores the signals in the memory 18 (see FIG. 4 described later) in association with the ID 2b, thereby allowing the entrance door 31 to store the signals. Initially register the corresponding electronic lock function.

  Note that the second registration method or the third registration method can also be used as a method of registering the traffic card function. Also, the first registration method can be used as a method for registering the electronic lock function. That is, any specific function that can be registered can be registered using any one of the first to third registration methods.

(2) Configuration of Wrist Watch 3 A specific configuration of the wrist watch 3 will be described with reference to FIG. As shown in FIG. 4, the wristwatch 3 of this embodiment includes a battery 26, a power supply circuit 27, and a non-contact power supply / reception unit 28.

(3) Processing of Control Device on Target Device in Specific Function Next, function execution processing executed in the control device on the target device side that realizes the specific function will be described with reference to FIG. The control device on the target device side here refers to the control device 7 in the automatic ticket gate 6 illustrated in FIG. 1 for the traffic card function, for example, and the control device 32 illustrated in FIG. 3 for the electronic lock function, for example. Point to. The function execution process shown in FIG. 6 is a schematic and generalized process executed by each control device corresponding to each specific function.

  The control device repeatedly executes the function execution process shown in FIG. 6 at a predetermined control cycle. When the control device starts the function execution process of FIG. 6, the control device transmits a request signal RQ in S10. As described above, the wireless communication system and communication frequency to be used are determined for each specific function, and all signals transmitted and received in the function execution process are transmitted and received by the corresponding wireless communication system.

  In S15, the control device determines whether or not a response signal RS corresponding to itself, that is, a response signal RS for the request signal RQ transmitted in S10 has been received. When the response signal RS corresponding to itself is not received (S15: NO), this function execution process is terminated. When the response signal RS corresponding to itself is received (S15: YES), the process proceeds to S20.

  The control device may receive a plurality of response signals RS corresponding to a plurality of specific functions. In this case, the control device narrows down the corresponding response signal RS based on the wireless communication method, and further reduces the response signal RS to the response signal RS. Based on the included function code, the response signal RS corresponding to the corresponding specific function is specified. The function code is an individual code for each function module, is registered in the memory 18 as function registration information, and is transmitted together with the ID information when the response signal RS is transmitted. Based on the function code included in the response signal RS, the control device can determine whether or not the response signal RS is from the function module corresponding to itself. The determination may be made based on the ID.

  Further, not only the response signal RS but also when the functional module transmits any signal to the corresponding control device in the wristwatch 3, an ID and a function code are added to the transmission target signal. Each time the control device receives a signal from the outside, the control device is a signal corresponding to itself (that is, a signal to be processed by itself) based on at least one of the ID and the function code included in the received signal. If it is a signal corresponding to itself, processing based on the signal is performed.

  In S20, the authentication process based on the ID included in the response signal RS (response signal RS corresponding to the control device) is performed. If the received ID does not match the ID stored in the control device, it is determined that the authentication has failed (S20: NO), and the process proceeds to S55. In S55, a predetermined error process is performed and the function execution process is terminated. If the received ID matches the ID stored in the control device, it is determined that the authentication is successful (S20: YES), and the process proceeds to S25.

  In S25, an authentication permission signal is transmitted. In S30, it is determined whether function information is received from the corresponding IC card or wristwatch 3 in response to the authentication permission signal. The function information is various information necessary for executing the specific function. In the wristwatch 3, any or all of the function registration information registered for each specific function (each function module) corresponds to the function information. Since the function code is transmitted as the response signal RS as described above, it may be excluded from the function information. Further, the function information may be transmitted in a plurality of times according to a request from the control device, instead of being transmitted all at once.

  When the function information is not received (S30: NO), the process proceeds to S55 error processing. When the function information is received (S30: YES), a function corresponding to the specific function is executed based on the received function information in S35. For example, in the case of a control device for a traffic card function, the gate is opened to allow the user to pass. Further, for example, in the case of a control device with an electronic lock function, the lock mechanism 33 is controlled to be unlocked. However, if the content of the function information is such that the specific function should not be executed, the specific function is not executed. For example, when the charge fee is insufficient, the gate is kept closed and a specific process (for example, alarm output) is performed.

  In S40, the function information is updated. For example, in the transportation card function, it is conceivable to update the charge fee or update the usage history. Further, for example, in the electronic lock function, it is conceivable to update the room entry history and the use history.

  In S45, the function information updated in S40 is transmitted to the communication target (IC card or wristwatch 3). Moreover, it transmits also to a server as needed, and also keeps the newest function information also in a server.

  In S50, it is determined whether or not a completion notification is received from the corresponding IC card or wristwatch 3. When the completion notification is not received (S50: NO), the process proceeds to S55 error processing. When the completion notification is received (S50: YES), this function execution process is terminated.

(4) Functional Module Processing (4-1) Initial Registration Processing by First Registration Method Next, among the initial registration processing included in each functional module in the wristwatch 3, the initial registration processing by the first registration method. This will be described with reference to FIG. The first registration method is a method for performing registration by intercepting communication between the control device and the IC card, as described with reference to FIG. When one of the installed function modules is activated in the wristwatch 3 and a necessary operation for performing initial registration by the first registration method is performed, the initial registration process shown in FIG. 7 is started. Note that the wireless communication method used when performing the initial registration process is also a wireless communication method corresponding to the corresponding specific function.

  When any functional module starts the initial registration process of FIG. 7, the request signal RQ transmitted from the control device is received in S105. In S110, the response signal RS transmitted from the IC card with respect to the request signal RQ is received. In S115, the authentication permission signal transmitted from the control apparatus with respect to the response signal RS is received. In S120, the function information transmitted from the IC card in response to the authentication permission signal is received. In S125, the update function information transmitted from the control device for the function information is received. In S130, a completion notification transmitted from the IC card for the updated function information is received. In S135, the information received from the control device and the IC card in each process from S105 to S130 is associated and registered as information corresponding to the functional module. That is, the functional module is registered so that it can function as a corresponding IC card. As a result, for the registered specific function, the function equivalent to the case of holding the IC card can be executed by holding the wristwatch 3 over the antenna of the corresponding control device.

(4-2) Function Utilization Processing Next, function utilization processing included in each function module in the wristwatch 3 will be described with reference to FIG. In the wristwatch 3, the function use processing included in the function module is periodically and repeatedly executed for the function module for which the initial registration has already been completed among the installed function modules. When there are a plurality of function modules for which initial registration has been completed, each function use process for each of the plurality of function modules is periodically executed in a predetermined order or as multitask processing (parallel processing). The Here, for simplification of explanation, it is assumed that the initial registration is completed for only one specific function module, and the function use process included in the function module is periodically executed. Continue the explanation.

  When the functional module for which initial registration has been completed starts the function use processing of FIG. 8, it is determined in S160 whether a request signal RQ has been received from the corresponding control device. As described above, when the request signal RQ is received, it can be determined based on the function code included in the request signal RQ.

  When the request signal RQ corresponding to itself is not received (S160: NO), this function use process is terminated. When the request signal RQ corresponding to itself is received (S160: YES), the response signal RS is transmitted in S165. As described above, the response signal RS includes at least an ID and a function code.

  In S170, it is determined whether an authentication permission signal for the response signal RS transmitted in S165 has been received from the control device. If the corresponding authentication permission signal is not received (S170: NO), a predetermined error process is performed in S195, and this function use process is terminated. When the corresponding authentication permission signal is received (S170: YES), the function information is transmitted in S175. The function information transmitted here is a part or all of various information registered (stored) in the memory 18 as function registration information as described above.

  In S180, it is determined whether update function information for the function information transmitted in S175 has been received from the control device. If the corresponding update function information is not received (S180: NO), the process proceeds to S195 for error processing. When the corresponding update function information is received (S180: YES), the currently registered function registration information is updated in S185 according to the received update function information. For example, when the latest charge charge information is received as the update function information corresponding to the A Electric Railway functional module, if the received charge charge is changed from the currently registered charge charge, registration Update the content to the received charge fee. After updating the function information, a completion notice is transmitted in S190, and the function use process is terminated.

(4-3) Initial Registration Processing by Second Registration Method Of the initial registration processing included in each functional module in the wristwatch 3, the initial registration processing by the second registration method will be described with reference to FIG. To do. As described with reference to FIG. 3B, the second registration method is a method in which the wristwatch 3 directly reads and registers function information in the IC card.

  In the wristwatch 3, when any functional module starts the initial registration process by the second registration method shown in FIG. 9A, the request signal RQ is transmitted in S205. In S210, it is determined whether or not a response signal RS to the request signal RQ has been received from the IC card. When the response signal RS is not received (S210: NO), a predetermined error process is performed in S240, and this initial registration process is terminated. When the response signal RS is received (S210: YES), the process proceeds to S215.

  In S215, an authentication permission signal is transmitted. In S220, it is determined whether or not the function information for the authentication permission signal has been received from the IC card. When the function information is not received (S220: NO), the process proceeds to S240 error processing. When the function information is received (S220: YES), the updated function information is transmitted in S225. The update function information transmitted here is dummy information for initial registration, and does not substantially update the function information in the IC card.

  In S230, it is determined whether or not a completion notification for the dummy update function information has been received from the IC card. When the completion notification is not received (S230: NO), the process proceeds to S240 error processing. If a completion notification is received (S230: YES), the process proceeds to S235. In S235, the information received from the IC card in S210, S220, and S230 is associated with the information transmitted in S205, S215, and S225 and registered as information corresponding to the functional module. This completes the initial registration.

(4-4) Initial Registration Processing by Third Registration Method Of the initial registration processing included in each functional module in the wristwatch 3, the initial registration processing by the third registration method will be described with reference to FIG. To do. The third registration method is a method of registering using the relay registration device 37 as described with reference to FIG. As a premise, it is assumed that the relay registration device 37 has already acquired necessary information from the IC card by communicating with the IC card.

  In the wristwatch 3, when any functional module starts the initial registration process by the third registration method shown in FIG. 9B, the registration information is requested to the relay registration device 37 in S260. In S265, various information transmitted from the relay registration device 37 in response to the request in S260 is received. Here, the various information received from the relay registration device 37 includes at least a request signal RQ, a response signal RS, function information, and a completion notification. In S270, the various signals received in S265 are associated and registered as information corresponding to the functional module. This completes the initial registration.

(5) Description of Electronic Key Function Module for Car (5-1) Configuration of Vehicle 50 Next, among the functional modules of the wristwatch 3, the electronic key function module for the car that performs the function as the electronic key for the car. This will be described with reference to FIGS. 10 and 11. First, the configuration of the vehicle 50, which is the target device for the function, will be described with reference to FIG.

  The vehicle 50 of this embodiment is a vehicle having an engine (internal combustion engine) as a driving source for travel. As shown in FIG. 10, the vehicle 50 includes a control unit 51. The control unit 51 includes a microcomputer provided with a CPU, ROM, RAM, I / O, etc. (not shown). The control unit 51 controls various circuits and functional blocks in the vehicle 50 including each unit connected to the control unit 51.

  In the present embodiment, the various circuits and functional blocks controlled by the control unit 51 include at least an engine unit 56, a brake unit 57, a steering unit 58, a door 59, a horn 60, and a blinker 61. Note that a plurality of doors 59 and winkers 61 are actually provided.

  The engine unit 56 includes an engine and an engine control unit that controls the engine. The control unit 51 can control the operation of the engine via the engine control unit in the engine unit 56. The brake unit 57 includes a brake mechanism provided in the vehicle 50 and a brake control unit that controls the brake mechanism. The steering unit 58 includes a steering wheel 58a (see FIG. 10B) that is directly operated by the user, a steering mechanism that steers the wheels of the vehicle 50, and a steering control unit that controls the steering mechanism (both not shown).

  The control unit 51 executes various functions based on various programs and data stored in the memory 55. The memory 55 is a nonvolatile memory capable of electrically rewriting stored contents, and is a flash memory in the present embodiment. The data stored in the memory 55 includes ID information 55a.

  The ID information 55a includes ID information unique to the vehicle 50. This ID information is the same as the ID information stored in the electronic key (not shown), and is the same as the ID information included in the electronic key function module for automobile in the wristwatch 3. That is, the ID information 55a includes the basic ID 3 described above and three security IDs (ID 3a, ID 3b, ID 3c). More specifically, each security ID is an engine ID 3a, a steering ID 3b, and a brake ID 3c.

  The basic ID 3 is a basic ID when operating the vehicle 50 using the electronic key function. In the vehicle 50, when the basic ID received from the outside does not match the basic ID 3, all functions in the electronic key function are restricted. That is, the door 59 is not in the unlock standby state, and the engine unit 56 is not in the start standby state. Therefore, the door 59 cannot be opened and the engine cannot be started.

  Further, even if the basic ID matches the basic ID 3, if the security IDs do not match, the operation is restricted for the function corresponding to the security ID that does not match. For example, when the engine ID received from the outside does not match the engine ID 3 a stored in the memory 55, the start standby state is not set. For example, when the steering ID received from the outside does not match the steering ID 3b stored in the memory 55, the steering lock is not released. Further, for example, when the brake ID received from the outside does not match the brake ID 3c stored in the memory 55, the parking brake is forcibly applied regardless of the user operation (when the parking brake is applied and the vehicle is stopped) Force that state).

  In addition, the vehicle 50 includes an in-vehicle transmitter 52, an in-vehicle transmitter 53, and a receiver 54 as communication means for specifically executing smart communication for realizing the electronic key function for automobiles.

  The vehicle interior transmitter 52 and the vehicle interior transmitter 53 periodically transmit a request signal RQ based on a command from the control unit 51. Note that the request signal RQ transmitted from the vehicle interior transmitter 52 and the request signal RQ transmitted from the vehicle interior transmitter 53 are not exactly the same content, but include at least identification information indicating the transmission source.

  In practice, a plurality of vehicle interior transmitters 52 and vehicle interior transmitters 53 are provided. That is, a plurality of vehicle interior transmitters 53 form a vehicle interior detection area (an area in which a request signal RQ from any vehicle interior transmitter 53 can be received) in the vehicle 50. In addition, a plurality of outside-vehicle transmitters 52 form an outside-vehicle detection area (an area in which a request signal from any one of the outside-vehicle transmitters 52 can be received) around the vehicle 50.

  The receiver 54 can receive various signals transmitted from the electronic key or the wristwatch 3. The signal received by the receiver 54 from the electronic key or the wristwatch 3 includes a response signal RS to the request signal RQ transmitted from each of the transmitters 52 and 53. When the electronic key or the wristwatch 3 receives the request signal RQ, the response signal RS corresponding to the request signal RQ is added with the identification information included in the request signal RQ. Therefore, when the response signal RS is received by the receiver 54, the control unit 51 of the vehicle 50 at least based on the identification information added to the response signal RS, the electronic key or the wristwatch 3 that is the transmission source. It can be determined whether the vehicle exists in the room 50 or outside the vehicle.

  The vehicle 50 according to the present embodiment can exhibit functions equivalent to those of a conventional electronic key system through smart communication with the wristwatch 3. For example, when the user with the wristwatch 3 enters the outside detection area of the vehicle 50, the request signal RQ from the outside transmitter 52 is received by the wristwatch 3 as illustrated in FIG. . In this case, in the wristwatch 3, the vehicle electronic key function module starts a substantial operation based on the received request signal RQ, and the response signal RS is transmitted by smart communication. When this response signal RS is received by the receiver 54 of the vehicle 50 and the ID collation is successful, the door 59 enters the unlock standby state.

  Thereafter, when the user enters the vehicle 50 and the wristwatch 3 enters the vehicle interior detection area, the request signal RQ from the vehicle interior transmitter 53 is received by the wristwatch 3 as illustrated in FIG. Is done. In this case, in the wristwatch 3, the vehicle electronic key function module continues to operate substantially based on the received request signal RQ, and the response signal RS is transmitted by smart communication. The contents of the response signal RS in this case are the above-described three security IDs. When this response signal RS (that is, three security IDs) is received by the receiver 54 of the vehicle 50 and all the verification of each security ID is successful, the engine enters a start standby state, the steering lock is released, and the parking brake is released. It becomes possible.

(5-2) Electronic Key Function Processing Next, among various processes executed by the automotive electronic key function module in the wristwatch 3, in-vehicle communication processing executed particularly for the request signal RQ from the in-vehicle transmitter 53. Will be described with reference to FIG.

  When the vehicle electronic key function module starts the vehicle interior communication process of FIG. 11, it determines whether or not the request signal RQ is received from the vehicle interior transmitter 53 in S305. When the request signal is not received from the vehicle interior transmitter 53 (S305: NO), this vehicle interior communication process is terminated. When the request signal is received from the vehicle interior transmitter 53 (S305: YES), the process proceeds to S310.

  In S310, the engine ID 3a is transmitted. In S315, the steering ID 3b is transmitted. In S320, the brake ID 3c is transmitted. In S325, it is determined whether a vehicle interior function authentication signal is received from the vehicle interior transmitter 53. When the vehicle interior function authentication signal is not received (S325: NO), predetermined error processing is performed in S330, and this vehicle interior communication processing is terminated. When the vehicle interior function authentication signal is received (S325: YES), the vehicle interior communication processing is terminated as it is.

(5-3) Vehicle Interior Authentication Process in Vehicle 50 Next, the vehicle interior authentication process executed by the control unit 51 of the vehicle 50 will be described with reference to FIG. The control unit 51 of the vehicle 50 periodically and repeatedly executes the vehicle interior authentication process of FIG. When the control unit 51 of the vehicle 50 starts the vehicle interior authentication process of FIG. 12, it sets an error flag in S500. In S505, the request signal RQ is transmitted from the vehicle interior transmitter 53.

  In S510, it is determined whether the receiver 54 has received the engine ID. When the engine ID is not received (S510: NO), the vehicle interior authentication process is terminated. When the engine ID is received (S510: YES), in S515, the received engine ID is authenticated, and it is determined whether the authentication is successful. Specifically, it is determined whether or not the received engine ID matches the engine ID 3a stored in the vehicle 50 as the ID information 55a. If they match, it is determined that the authentication is successful.

  If the engine ID authentication fails (S515: NO), the vehicle interior authentication process is terminated. If the engine ID authentication is successful (S515: YES), an engine start standby process is performed in S520, and the process proceeds to S525. The engine start standby process is a predetermined process including a process of shifting the engine to a start standby state.

  In S525, it is determined whether the receiver 54 has received the steering ID. If the steering ID is not received (S525: NO), the vehicle interior authentication process is terminated. If the steering ID is received (S525: YES), in S530, the received steering ID is authenticated, and it is determined whether the authentication is successful. Specifically, it is determined whether or not the received steering ID matches the steering ID 3b stored in the vehicle 50 as the ID information 55a. If they match, it is determined that the authentication is successful.

  If the authentication of the steering ID fails (S530: NO), the vehicle interior authentication process is terminated. If authentication of the steering ID is successful (S530: YES), the steering lock is released in S535, and the process proceeds to S540.

  In S540, it is determined whether the receiver 54 has received the brake ID. When the brake ID is not received (S540: NO), the vehicle interior authentication process is terminated. When the brake ID is received (S540: YES), in S545, the received brake ID is authenticated, and it is determined whether the authentication is successful. Specifically, it is determined whether or not the received brake ID matches the brake ID 3c stored in the vehicle 50 as the ID information 55a.

  If the brake ID authentication fails (S545: NO), the vehicle interior authentication process is terminated. If the brake ID authentication is successful (S545: YES), the parking brake release standby process is performed in S550, and the process proceeds to S555.

  The fact that the process has proceeded to S555 means that the authentication has succeeded for all three security IDs. Therefore, in S555, the error flag is cleared. In step S560, the vehicle interior authentication signal is transmitted, and the vehicle interior authentication process is terminated.

(5-4) Vehicle Operation Monitoring Process in Vehicle 50 Next, the vehicle operation monitoring process executed by the control unit 51 of the vehicle 50 will be described with reference to FIG. The control unit 51 of the vehicle 50 periodically and repeatedly executes the vehicle operation monitoring process of FIG. When the vehicle operation monitoring process of FIG. 13 is started, the control unit 51 of the vehicle 50 determines whether or not the engine is operating in S605. If the engine is operating (S605: YES), it is determined in S620 whether an error flag is set.

  If the error flag is not set (S620: NO), the vehicle operation monitoring process is terminated. If the error flag is set (S620: YES), an alarm output process is performed in S625. Specifically, the horn 60 is sounded or the blinker 61 is blinked. If the engine is stopped in S605, the process proceeds to S610.

  In S610, it is determined whether or not the steering lock is released. When the steering lock is released (S610: YES), the process proceeds to S620 and subsequent steps. That is, it is determined whether or not an error flag is set. If it is set, an alarm output process (S625) is performed. When the steering lock is not released (S610: NO), the process proceeds to S615.

  In S615, it is determined whether or not the parking brake is released. When the parking brake is released (S615: YES), the process proceeds to S620 and subsequent steps. If the parking brake has not been released (S615: NO), the vehicle operation monitoring process is terminated.

  The fact that the error flag is set means that at least one of the three security IDs has failed to be authenticated. In such a case, if the engine is operating, the steering lock is released, or the parking brake is released, the vehicle 50 may be operated by an unauthorized user. Therefore, an alarm is output when the engine is operating, the steering lock is released, or the parking brake is released even though the error flag is set.

(6) Effects of Embodiment, etc. In the non-contact type functional system of the present embodiment described above, usually between an IC card or a similar medium and a target device on the service provider side (for example, the control device described above). A specific function (service) realized by wireless communication can be realized by wireless communication between the wristwatch 3 and the target device.

  That is, a specific function realized by an IC card or a similar medium can be registered in the wristwatch 3. And about the registered specific function, the wristwatch 3 behaves similarly to an IC card or a medium similar to the target device. In addition, a plurality of specific functions can be registered in the wristwatch 3. That is, it can be considered that functions of a plurality of IC cards or the like of different services are integrated in the wristwatch 3.

Therefore, according to the wristwatch 3 of the present embodiment, convenience for the user when receiving a plurality of services by non-contact communication using an IC card or a similar medium is improved.
Further, in this embodiment, the registration of the specific function to the wristwatch 3 can be performed by at least three kinds of methods of the first registration method to the third registration method. In any registration method, it is common that the wristwatch 3 acquires necessary information from an IC card or the like and stores it in the memory 18. Thus, by acquiring necessary information from an IC card or the like, the corresponding specific function can be easily registered in the wristwatch 3.

  Of the three types of initial registration methods, the first registration method is such that the wristwatch 3 receives (intercepts) signals transmitted and received between the IC card and the corresponding device when wireless communication is being performed. And register. In the first registration method, the wristwatch 3 simply needs to be able to intercept signals transmitted and received between the two, so that the initial registration can be performed relatively easily.

  On the other hand, the second registration method is a method in which the wristwatch 3 acts as a control device in a pseudo manner to directly communicate with the IC card to acquire and register necessary information from the IC card. In the second registration method, it is not necessary to actually hold the IC card over a corresponding device, and therefore, if there is an IC card, registration can be easily performed regardless of the location.

  The third registration method is a method of registering using the relay registration device 37. In the third method, although a device called the relay registration device 37 is necessary, the wristwatch 3 can easily and reliably obtain information necessary for registration from the relay registration device 37.

  In addition, the wristwatch 3 of the present embodiment can register various types of specific functions. Specific functions that can be registered include at least a transportation card function, an electronic money function, an electronic lock function, and an electronic electronic key function for automobiles. For this reason, various specific functions can be realized (a variety of services can be enjoyed) simply by possessing only the wristwatch 3 without having a medium such as an IC card.

  Further, in the automobile electronic key function, when the wristwatch 3 enters the room of the vehicle 50, a plurality of security IDs (ID3a, ID3b, ID3c) are transmitted from the wristwatch 3. These security IDs are IDs corresponding to the engine unit 56, the steering unit 58, and the brake unit 57, respectively. If authentication fails for any security ID, the function corresponding to that security ID is restricted.

  For example, even if the authentication of the engine ID 3a is successful and the engine can be started, if the authentication of the steering ID 3b fails, the steering lock is not released and the steering operation cannot be performed. That is, in the vehicle 50, multiple locks other than the basic ID can be locked multiple times. Moreover, when all the security IDs have not been successfully authenticated, an alarm is output when the engine is operating, the steering lock is released, or the parking brake is released. Therefore, it becomes possible to provide the vehicle 50 with very high security performance.

[Other Embodiments]
(1) When the wristwatch 3 receives a request signal RQ corresponding to any specific function, which specific function the request signal RQ corresponds to (that is, which functional module should correspond) A method for determining the above can be considered as appropriate, including the method described above. The request signal RQ may be determined based on the content of the request signal RQ, or may be determined based on the signal or the like in the case where the request signal RQ is transmitted with a function code or a signal equivalent thereto. . Of course, it goes without saying that the reception frequency and communication method may be used as one of the determination criteria.

  Further, it may be determined which specific function the request signal corresponds to based on the position where the request signal RQ is received using the GPS function. For example, when the position of the wristwatch when receiving the request signal RQ is home, it can be determined that the request signal RQ corresponds to the home key function module.

  (2) Conversely, when a plurality of response signals RS are received with respect to the request signal RQ, the corresponding device side (control device or the like) corresponding to the specific function determines which response signal RS should respond. The method can be considered as appropriate including the method described above. The content of the response signal RS itself (including at least one of the ID and the function code) may be determined, or in the case of a specification in which another signal is added to the response signal RS, the determination can be made based on the signal. You may do it.

  (3) In the wristwatch 3, a fingerprint authentication function may be added. Further, when the wristwatch 3 receives the request signal RQ and it is unclear which specific function the request signal RQ corresponds to, all registered specific functions (all registered function modules) The response signal RS corresponding to) may be transmitted. Then, the corresponding device may extract the corresponding response signal RS from the plurality of response signals RS.

  A specific example will be described with reference to FIGS. FIG. 14 shows another embodiment of the function use process described in FIG. However, the function use process of FIG. 14 is not a process executed by individual function modules but a process executed by an integrated module that is an application that controls the individual function modules.

  When the integrated module starts the function use process of FIG. 14, in S705, it is determined whether or not a fingerprint is detected by the fingerprint detection unit 24. If no fingerprint is detected, the function use process is terminated. If a fingerprint is detected (S705: YES), fingerprint authentication processing is executed in S710. Specifically, it is determined whether the fingerprint data of the legitimate user registered in the memory 18 in advance matches the detected fingerprint data. If they match, it is determined that the authentication is successful.

  In S715, it is determined whether fingerprint authentication is successful. If the fingerprint authentication fails (S715: NO), this function use process is terminated. If the fingerprint authentication is successful (S715: YES), the process proceeds to S720. That is, unless the fingerprint is detected and the fingerprint authentication is successful, the process does not proceed to S720 and subsequent steps.

  In S720, it is determined whether a request signal RQ is received. When the request signal RQ is not received (S720: NO), this function use process is terminated. When the request signal RQ is received (S720: YES), the response signal RS is transmitted from all the functional modules that are initially registered in S725. Specifically, the response signal RS is sequentially transmitted at a specific time interval Tx.

  In S730, it is determined whether an authentication permission signal and function specifying information are received. The function specifying information is information for specifying a function module, and is information that can specify a function module corresponding to the request signal RQ received in S720. If the authentication permission signal and the function specifying information are not received (S730: NO), a predetermined error process is performed in S760, and the function use process is terminated. When the authentication permission signal and the function specifying information are received (S170: YES), the process proceeds to S740. The processing after S740 is the same as the processing after S175 in FIG.

  An example of the function execution process on the control device side with respect to the function use process of FIG. 14 described above is shown in FIG. FIG. 15 is another example of the function execution process described in FIG. When the control device starts the function execution process of FIG. 15, a request signal RQ is transmitted in S805.

  In S810, it is determined whether a response signal RS has been received. When the response signal RS is not received (S810: NO), this function execution process is terminated. When the response signal RS is received (S810: YES), the process proceeds to S815. In S815, the received response signal RS is stored in the memory 18 or RAM (not shown).

  In S820, it is determined from the reception timing of the response signal RS received immediately before whether or not the predetermined standby time Tw has elapsed without receiving a new response signal RS. The waiting time Tw is set to a time longer than at least the time interval Tx. If the standby time Tw has not yet elapsed (S820: NO), it is determined again in S825 whether the response signal RS has been newly received. When the response signal RS is not received (S825: NO), the process returns to S820. If the response signal RS is received (S825: YES), the received response signal RS is stored in the memory 18 or RAM in S830, and the process returns to S820.

  If the standby time Tw has elapsed in S820, the process proceeds to S835. In S835, among the received response signals RS (stored in the memory or RAM), there is a response signal RS (hereinafter also referred to as “compatible response signal RS”) that is suitable for itself (a specific function corresponding to the control device). Determine whether or not. If there is no matching response signal RS, the process proceeds to S875 for error processing. If there is a conformance response signal RS, the authentication processing of the ID included in the conformance response signal RS is performed in S840. If ID authentication fails, the process proceeds to S875 for error processing. If the ID authentication is successful, in S845, an authentication permission signal and function identification information acquisition are transmitted. The function specifying information is information indicating a specific function corresponding to the adaptation response signal RS, and is information indicating which function module from which the response signal RS is adapted to itself. The specific function information is determined to be received in S730 in FIG. The processing after S850 is the same as the processing after S30 in FIG.

  When a plurality of response signals RS are transmitted collectively from the wristwatch 3, a transmission method different from the method of transmitting at a constant time interval Tx as described above may be employed. For example, a plurality of response signals RS may be transmitted by time division multiplex communication.

  Further, instead of fingerprint authentication or in addition to fingerprint authentication, other authentication methods may be employed. For example, face authentication based on the user's face image captured by the imaging unit 23 may be performed. For example, voice authentication (voice print authentication) based on the user's voice input from the voice input unit 21 may be performed.

  (4) It is not essential to provide an application (functional module) for each specific function. As in the integrated module described above, a plurality of types of specific functions may be registered by one application.

Also, for example, the functions of the present invention may be installed in various other terminals that do not have a mobile phone function. Further, for example, a dedicated portable terminal specialized for the function of the present invention may be configured.

  In addition, as a usage form of the mobile terminal to which the present invention is applied, it may be a usage form in which the mobile terminal is held on the body like the wristwatch 1 of the above-described embodiment, or a mobile phone or a smartphone. The usage form may be such that the user directly holds the portable terminal by hand and holds it over the target device. In addition, for example, the portable terminal may be stored and held in a neck-mounted card holder, and the card holder may be held over the target device if necessary, or the neck strap may be directly attached to the portable terminal. It may be a usage form that is held on the top. In addition, for example, a portable terminal is attached to an expandable / retractable reel-type strap, and is held by hanging it on the neck or on the waist, and the portable terminal is held over the target device while extending the reel as necessary. It may be.
