It is electrically connected by soldering. In FIG. 2, a portion where the conducting wire 36 is present is indicated by a two-dot chain line.

  The electrical configuration of the human body communication terminal device main body 21 will be described. The human body communication terminal device main body 21 has a storage unit 22 on the terminal side, a human body communication circuit unit 24a, a human body communication electrode 24b, and a terminal side control unit 26.

  The terminal-side control unit 26 is configured by a general microcomputer including a CPU, a ROM, a RAM, and the like, and performs an arithmetic operation using a software program stored in advance to execute processing described later.

  The storage unit 22 is configured by a rewritable nonvolatile memory such as a flash memory, and is configured to be able to store a personal identification ID or the like as usage authority information.

  The human body communication circuit unit 24a includes a modulation circuit, a demodulation circuit, an amplifier circuit, and the like, and modulates a signal supplied from the terminal side control unit 26 and outputs the modulated signal to the human body communication electrode 24b. A signal received through the communication electrode 24b is demodulated and provided to the terminal-side control unit 26.

Any method and configuration may be used, such as communication using change. In short, all methods and configurations for performing communication using the human body 80 as a communication path are included.

  FIG. 6 is a flowchart showing the operation of the human body communication terminal device.

  First, the human body communication terminal device 20 is in a sleep mode with less power consumption in a normal state after the completion of the processing described later, and receives a signal from the authority writing device 40 or the authentication lock device 60 via the human body 80. For example, when an electric signal having a predetermined voltage level or higher is received via the human body communication electrode 24b, the operation is started and the operation mode is shifted.

  Then, after the activation of the human body communication terminal device 20, first, in step S1, it is determined whether or not human body communication is established. Here, if the establishment of the human body communication is denied, the process returns to step S1, and if it is determined that the human body communication is established, the process proceeds to step S2.

  In step S2, it is determined whether the signal received by human body communication includes a write request or a read request.

  If it is determined that a write request is included, the process proceeds to step S3. In step S3, the personal identification ID included in the signal received by human body communication is written in the storage unit 22, and the process is terminated.

  On the other hand, if it is determined in step S2 that a read request is included, the process proceeds to step S4. In step S4, the personal identification ID stored in the storage unit 22 is read out and transmitted to the outside through the human body communication circuit unit 24a and the human body communication electrode 24b, and the process is terminated.

  Such a human body communication terminal device 20 is given to each user. Even if it is a form that is granted permanently or continuously to each user (that is, a form that is given as a dedicated product), it is given to each user every time the system is used. (That is, a form used as a shared product).

<Authority writing device>
FIG. 7 is a perspective view showing the authority writing device. As shown in FIG. 4 and FIG. 7, the authority writing device 40 includes an authority writing side storage unit 42, a human body communication circuit unit 44 a and a human body communication electrode 44 b, an authority writing control unit 46, and personal authentication. Part 48.

  The authority writing control unit 46 is configured by a general microcomputer including a CPU, a ROM, a RAM, and the like, and performs a calculation operation by a software program stored in advance to execute processing described later.

  The storage unit 42 is configured by a rewritable nonvolatile memory such as a flash memory, and can store use authority writing information in which the personal authentication information is associated with the personal identification ID that is the use authority information of the lock target. It is configured. Here, fingerprint data of each user registered in advance is stored as personal authentication information. The usage authority writing information is set and registered in advance by the administrator of this system.

  The human body communication circuit unit 44a and the human body communication electrode 44b have the same configuration as the human body communication circuit unit 24a and the human body communication electrode 24b, and perform human body communication using the human body 80 as a communication path.

  The personal authentication unit 48 is configured to acquire personal authentication information. Here, when the user's fingertip touches the touch unit 40b provided so as to be exposed to the case 40a of the apparatus 40, the personal authentication unit 48 acquires the fingerprint of the fingertip as personal authentication information, and writes the authority. This is given to the control unit 46.

  The human body communication electrode 44b is installed in the touch unit 40b. When the fingertip is brought into contact with the touch unit 40b, the fingerprint data is acquired as personal authentication information, and the human body communication circuit unit 44a and the human body communication are provided. Communication through the human body 80 is established from the electrode 44b.

  As described above, when the personal authentication unit 48 is a biometric authentication device that accepts a living body by contact, the human body communication electrode 44b is in contact with a part of the personal authentication unit 48 where a part of the living body such as a finger contacts. It is preferable that human body communication can be established simultaneously with personal authentication. Thus, writing to the human body communication terminal device 20 can be performed at the time of personal authentication by biometric contact, which is convenient.

  The personal authentication unit 48 is not limited to the above example, and may be configured to acquire authentication information unique to each person such as a vein, a retina, and a voiceprint. As described above, if a biometric authentication device that acquires information specific to a biometric is used as the personal authentication unit 48, the user can conveniently perform personal authentication by hand.

  Further, as described above, the personal authentication unit not only acquires authentication information unique to the living body, but is also stored in the ID card by a card reader that reads an ID card given to each person as an authentication terminal device. A configuration in which the identification ID is read as personal authentication information, or a configuration in which the personal authentication information is acquired by an input personal identification number may be used.

  In the case of these modified examples, the human body communication electrode 44b may be disposed at an arbitrary position where the user can contact the human body communication electrode 44b.

  FIG. 8 is a flowchart showing the operation of the authority writing device.

  After the start of processing, the authority writing device 40 determines whether or not personal authentication information has been acquired in step S11. If the acquisition of personal authentication information is denied, the process returns to step S11. On the other hand, when the personal authentication information is acquired by the personal authentication unit 48, the process proceeds to step S12.

  In step S12, it is determined whether or not human body communication is established. Here, if the establishment of human body communication is denied, the process returns to step S11. On the other hand, if it is determined that the human body communication is established, the process proceeds to step S13.

  In step S13, a personal identification ID as usage authority information is determined based on the acquired personal authentication information and usage authority writing information stored in the storage unit. That is, pattern matching or the like is performed between the acquired fingerprint data as personal authentication information and each fingerprint data stored in advance in the storage unit 42 to specify the personal identification ID, and then the process proceeds to step S14.

  In step S14, a signal including an instruction for writing the personal identification ID determined in step S13 is transmitted to the outside via the human body communication circuit unit 44a and the human body communication electrode 44b.

  Thereby, personal identification ID is written in the human body communication terminal device 20, and the process of the authority writing apparatus 40 is complete | finished.

  Such an authority writing device 40 is installed at a place where the user passes when using the system, here, at the entrance of the building B where the system is installed. Only one authority writing device 40 or a plurality of authority writing devices 40 may be installed in the entire system.

  However, the authority writing device 40 is not necessarily installed at the entrance of the building B. For example, when the security area and the open area are set in the building B, the authority writing device 40 may be at the entrance of the security area or at the entrance of a predetermined room. However, by installing the authority writing device 40 at the entrance of the area where the cabinet 10, the personal computer 18, the entrance door 16 and the like as lock objects are installed, when the user uses the entrance, It is convenient to be able to write usage authority information to the human body communication terminal device 20.

<Authentication lock device>
FIG. 9 is a diagram showing an example of a cabinet incorporating the authentication lock device, and FIG. 10 is a diagram showing a usage state of the cabinet.

  The cabinet 10 has a door-type storage portion 10a in the upper half, and a plurality of (here, three) drawer-type storage portions 10b in the lower half.

  The door-type storage unit 10a has a double-open door 12 that can be freely opened and closed. By opening the door 12, an article stored therein can be used, and the door 12 is maintained in a closed state. The state in which the articles housed inside cannot be used is maintained.

  The joint portion of the door 12 is disposed so as to overlap, and when the one door 12 is closed, the other door 12 cannot be opened. Further, a handle portion 12a as an operation portion and a latch mechanism portion 12b are attached to one door 12. The latch mechanism portion 12b is a mechanism that is incorporated in the door 12 and locks so as to keep the door 12 in a closed state. As such a mechanism, various configurations including a well-known mechanism for freely engaging and disengaging the claw portion to the cabinet body 11 side can be adopted. The handle portion 12a is attached to the outer surface side of the door 12 so that the posture can be freely changed. The latch mechanism 12b performs locking and unlocking operations in conjunction with the posture change of the handle 12a. By incorporating a lock unit 68, which will be described later, into the latch mechanism unit 12b, the latch mechanism unit 12b is maintained in a locked state or is in an unlocked state.

  The drawer-type storage unit 10b has a plurality of drawer units 13 that can be opened and closed, in other words, can be pulled out and pushed in, and by using each drawer unit 13, articles stored therein can be used. By maintaining the drawer portion 13 in the pushed-in state, the state in which the articles housed therein cannot be used is maintained.

  The drawer portion 13 is formed in a bowl shape that opens upward, and a handle portion 13a as an operation portion and a latch mechanism portion 13b are attached to the front surface thereof.

  The latch mechanism 13b is a mechanism that is incorporated in the front side portion of the drawer 13 and locks the drawer 13 so as to keep it closed. As such a mechanism, various configurations including a well-known mechanism can be adopted as in the case of the latch mechanism portion 12b. The handle portion 13a is attached to the front surface of the drawer portion 13 so that the posture can be freely changed, and the latch mechanism portion 13b performs locking and unlocking operations in conjunction with the posture change of the handle portion 13a. . By incorporating a lock unit 68, which will be described later, into the latch mechanism unit 13b, the latch mechanism unit 13b is maintained in a locked state or is in an unlocked state.

  The storage means is not limited to the above configuration. The whole storage means may be configured to be opened and closed by a door, or may be configured to have only a plurality of drawers. Further, the storage means is not limited to the cabinet 10 as described above, and may be a locker, a desk, a drawer of a side desk, or the like.

  The authentication lock device 60 is incorporated in the door 12 and the drawer 13 in the cabinet 10 as described above.

  As shown in FIG. 5, the authentication lock device 60 includes a storage unit 62 on the authentication lock side, a human body communication circuit unit 64a and a human body communication electrode 64b as a human body communication unit on the authentication lock side, an authentication control unit 66, And a lock portion 68.

  The authentication control unit 66 is configured by a general microcomputer including a CPU, a ROM, a RAM, and the like, and performs an arithmetic operation using a software program stored in advance to execute processing described later.

  The storage unit 62 is configured by a rewritable non-volatile memory such as a flash memory, and stores use permission / rejection information in which a personal identification ID as an identification code is associated with use permission / inhibition of the lock target. The use approval / disapproval information includes, for example, information that associates “use permission” or “use disapproval” as the use approval / disapproval with “0001”, which is the personal identification ID. Settings are registered.

  The basic configurations of the human body communication circuit unit 64a and the human body communication electrode 64b are the same as those of the human body communication circuit unit 24a and the human body communication electrode 24b. Here, the handle portions 12a and 13a are formed of a conductive material such as metal and are used as the human body communication electrode 24b (see FIG. 10). Accordingly, when the user touches the book handles 12a and 13a, human body communication is established between the human body communication terminal device 20 worn by the user and the authentication lock device 60. . However, the electrode 24b for human body communication may be configured to be exposed to the outside of the door 12 or the drawer portion 13 as an electrode dedicated to human body communication.

  The lock unit 68 is configured to be able to switch the lock target to a locked state or an unlocked state under the control of the authentication control unit 66. Here, the lock part 68 maintains the door 12 or the drawer | drawing-out part 13 which are lock | rock objects in a locked state or an unlocked state by restrict | limiting the operation | movement of the said latch mechanism parts 12b and 13b. As such a lock unit 68, for example, a combination of an actuator such as an electromagnetic plunger that operates to restrict or allow the locking and unlocking operations of the latch mechanism units 12 b and 13 b and a drive circuit that drives the actuator. Since it can be realized by various configurations including well-known techniques applied to various electronic lock devices such as combination, the description thereof is omitted here.

  Here, the example in which the authentication lock device 60 is incorporated in the door 12 or the drawer 13 has been described, but the authentication lock device 60 may be retrofitted to the door 12 or the drawer 13. In this case, the authentication lock device 60 is provided with a shutter-like shielding member that covers the handle portions 12a and 13a so that the handle portions 12a and 13a can be opened and shielded, and the handle portions 12a and 13a are operated by regulating the open state and the shielding state of the shielding member. What is necessary is just to set it as the structure which switches to a possible state and an inoperable state, and switches the door 12 or the drawer part 13 to a locked state or an unlocked state. In this case, for example, the human body communication electrode 24b may be provided on the surface of the shielding member.

  FIG. 11 is a flowchart showing the operation of the authentication lock device.

  First, in the initial state, the lock unit 68 is in a locked state in which the object to be used cannot be used.

  After the start of processing from this initial state, first, in step S21, it is determined whether or not human body communication is established. Here, if establishment of human body communication is denied, the process of step S21 is repeated. On the other hand, if it is determined that the user wearing the human body communication terminal device 20 touches the handle parts 12a and 13a and human body communication is established, the process proceeds to step S22.

  In step S22, a signal for requesting a personal identification ID is transmitted to the outside via the human body communication circuit unit 64a and the human body communication electrode 64b. Thereby, personal identification ID is transmitted from the human body communication terminal device 20, and personal identification ID is received via human body communication.

  In the next step S23, the presence / absence of use authority is determined based on the personal identification ID received through the human body communication and the use permission / denial information stored in the storage unit 62. For example, if “use permission” is associated with the received personal identification ID, it is determined that there is a use authority, and if “use not permitted” is associated with it, it is determined that there is no use authority. To do. If it is determined that there is no usage authority, the process returns to step S21. On the other hand, if it is determined that the use authority exists, the process proceeds to the next step S24.

  In step S24, the lock unit 68 performs an unlocking operation. Thereby, the latch mechanism parts 12b and 13b are unlocked, and the door 12 and the drawer part 13 can be opened and used. Thereby, the process is terminated.

  Here, the case where the authentication lock device 60 is incorporated in the cabinet 10 has been described as an example, but the same applies to the entrance door 16 of the room R.

  When the object to be used is the personal computer 18, the lock unit 68 is connected to an input / output terminal such as a USB port of the personal computer 18, and the personal computer 18 can be used when authorized. The use permission signal to be output may be output so that the personal computer 18 can be used in the unlocked state. In this case, the human body communication electrode 64b may be configured to be exposed to the outside as an electrode dedicated to human body communication. However, it is preferable to install the human body communication electrode 64b at a contact portion that the human body 80 touches directly or indirectly when using the personal computer 18, such as a desk, chair, mouse, or keyboard.

<Overall operation>
The overall operation of the authentication system configured as described above will be described based on the operation of the user.

  First, the user wears the human body communication terminal device 20 from the neck and enters the building B where the present system is installed. Since the authority writing device 40 is installed at the entrance of the building B, the user touches the touch part 40b of the authority writing device 40 with the finger. Then, the authority writing device 40 performs fingerprint authentication, identifies the user, and writes the personal identification ID into the human body communication terminal device 20 possessed by the user through human body communication.

  At this time, if the human body 80 is in an upright state, as shown in FIG. 12, the human body communication terminal device main body 21 itself is close to the front of the human body 80, and the conductor 36 of the linear member 34 is also connected to the human body. It is close to the neck that is part of 80. Therefore, a communication path including the human body 80 or the human body 80 and the conductor 36 is established between the human body communication terminal device main body 21 and the authority writing device 40. The human body communication terminal device main body 21 and the authority writing device 40 perform human body communication via this communication path.

  Alternatively, when the human body 80 is bent, the human body communication terminal apparatus main body 21 is separated by a distance L that is relatively far from the front of the human body 80 as shown in FIG. However, the conductive wire 36 of the linear member 34 is kept close to the neck, which is a part of the human body 80. For this reason, a communication path that passes through the human body 80 and the conductor 36 is stably established between the human body communication terminal device main body 21 and the authority writing device 40. The human body communication terminal device main body 21 and the authority writing device 40 perform human body communication via this communication path.

  Next, the user enters a predetermined room R in which the present system is installed through a passage. An authentication lock device 60 is installed at the entrance door 16 of the room R. The user grasps the handle portion of the entrance door 16 and tries to open the entrance door 16. At this time, human body communication is performed between the authentication lock device 60 and the human body communication terminal device 20 worn by the user, and a personal identification ID is transmitted from the human body communication terminal device 20 to the authentication lock device 60. Is done. At this time, even if the human body 80 is in an upright posture or a bent posture, a communication path that passes through the human body 80 and the conductor 36 is established in the same manner as described above. It can be established.

  As a result, the authentication lock device 60 determines whether or not the use authority exists, and if it is determined that the use authority exists, the authentication lock device 60 switches the entrance door 16 from the locked state to the unlocked state. As a result, the user can enter the room R by opening the door 16. On the other hand, if “use not permitted” is registered for the personal identification ID, it is determined that the user has no use authority and cannot enter the room. When the user enters the room R and closes the entrance door 16, the user is switched to the locked state again.

  Further, when the user enters the room R and uses each cabinet 10 or personal computer 18, the authentication lock device 60 provided in each cabinet 10 or personal computer 18 and the human body communication worn by the user. Human body communication is performed with the terminal device 20, and the presence / absence of usage authority is determined in the same manner as described above. At this time, whether the human body 80 is in an upright posture or a bent posture, a communication path passing through the human body 80 and the conductor 36 is stably established as described above. And when there is a use authority, each cabinet 10 and the personal computer 18 can be used now. When the use is finished, each cabinet 10 and the personal computer 18 are switched to an unusable locked state.

  According to the human body communication terminal device 20 and the holding member 30 for the human body communication terminal device main body 21 configured as described above, the linear member 34 that can be suspended from the neck of the human body 80 is electrically connected to the human body communication electrode 24b. Therefore, even when a person is bent, the conductor 36 can be kept relatively close to the human body 80. Thereby, the human body communication terminal device main body 21 can perform human body communication using the human body 80 as a communication path from the human body communication electrode 24b through the lead wire 36, and can stably perform human body communication regardless of the posture of the human body 80. Can be established.

  In particular, since the conductive wire 36 extends to a portion disposed around the neck of the human body 80, the conductive wire 36 is more reliably disposed near the human body 80, and the human body communication is more stable. It is established.

  Furthermore, since the conducting wire 36 is inserted into the insertion hole 35 a in the string member 35, the appearance and feel of the linear member 34 can be improved regardless of the material of the conducting wire 36. For example, by using a member in which a thread is knitted into a tube shape as the string member 35, it is possible to improve the touch, and it is possible to improve the design by adding coloring or a pattern.

<Modification>
Note that the authentication system to be applied is an example, and the application target is not limited to the example. For example, the human body communication terminal device 20 stores the writing date / time information of the personal identification ID in addition to the personal identification ID, and the use is permitted only for the writing date or for a predetermined time from the writing time. Possible conditions may be set.

  A mode in which the human body communication terminal device 20 in which the personal identification ID is fixedly written in advance without giving a personal identification ID to the human body communication terminal device 20 at the entrance of the building B or the like is provided to the user for a long period of time. It may be.

  The human body communication terminal device 20 is not limited to application in the authentication system as described above, but can be applied to various uses for performing various information communications.

  Further, the string member 35 in the human body communication terminal device 20 may be in the form of a resin tube.

  Moreover, the conducting wire 36 and the human body communication electrode 24b may be electrically connected by another electrical connection structure such as connector connection. In addition, here, only one end portion of the conducting wire 36 is electrically connected to the human body communication electrode 24b, but both end portions of the conducting wire 36 may be electrically connected to the human body communication electrode 24b.

  Moreover, although the conductor part demonstrated as the conducting wire 36 exists over the whole longitudinal direction of the linear member 34, it is not necessarily the case, for example in the longitudinal direction of the linear member 34, for example, You may exist in the substantially half part of the longitudinal direction of the linear member 34, etc. That is, since the conductor portion exists in the direction approaching the neck of the human body 80 from the holding portion 32, human body communication can be performed more stably than when the conductor portion does not exist. However, the conductor portion extends to a portion disposed around the neck of the human body 80 (particularly, a portion that contacts the neck), so that the conductor portion is brought close to the neck regardless of the posture of the human body 80. It is possible to perform human body communication stably.

  Instead of the linear member 34 having the string member 35 and the conductive wire 36, a linear member having a linear conductor exposed on the surface as a conductor portion may be used.

  For example, the linear member 134 shown in FIG. 14 has a linear conductor 136 formed of an annealed copper wire as a conductor portion. The linear conductor 136 is not covered and the surface of the conductor is exposed to the outside.

  The linear member 234 shown in FIG. 15 has a linear conductor 236 in which a thin soft copper wire is knitted into a net or a tube or string as a conductor portion.

  A linear member 334 shown in FIG. 16 has a linear conductor 336 formed as a chain by connecting a ring member 336a formed of a conductive material such as metal as a conductor portion.

  The linear member 434 shown in FIG. 17 has a linear conductor 436 in which spherical members 436a formed of a conductive material such as metal are connected in a beaded manner by connecting portions 436b having both ends formed in large diameters. have.

  In any of these examples, the linear member 34 can be used instead. In particular, the examples shown in FIGS. 15 to 17 have an advantage of excellent flexibility.

  Moreover, the structure of the holding | maintenance part 32 holding the human body communication terminal device main-body part 21 is not restricted to the said example. For example, a tongue piece portion that can be connected to the human body communication terminal device main body 21 itself by passing the linear members 34, 134, 234, 334, 434, or the like may be formed. In this case, the tongue piece portion functions as a holding portion. Further, when the conductor 36 of the linear member 34 or the linear members 134, 234, 334, 434 is electrically and mechanically connected to the human body communication electrode 24b as a conductor portion by soldering or connector connection, The connecting portion may function as a holding unit that holds the human body communication terminal device main body 21.
