  FIG. 1 is a block diagram illustrating a configuration of the mobile terminal A1. The portable terminal A1 has a built-in battery, and charging for the battery is derived from a wall plug or a wall surface, which is a power supply unit provided on the wall surface, with a plug connecting the portable terminal A1 body and the exterior of the body. This is done by connecting to an adapter such as a charging adapter at the end of the power cable. This connection is made by inserting the plug (power receiving unit) of the portable terminal A1 into the adapter (power supply unit).

  The mobile terminal A1 includes an authentication input device 1, an authentication determination unit 2, an anti-theft management unit 3 that controls a connection state between the mobile terminal A1 main body and the outside of the main body according to an authentication result, and a lock mechanism control unit 4. And a lock device 5 having a mechanism for connecting the main body of the portable terminal A1 and the outside of the main body and a mechanism for restricting the release of the connection between the main body of the mobile terminal A1 and the outside of the main body. In addition to the function keys attached to the mobile terminal A1, the authentication input device 1 inputs authentication information input or transmitted through another mobile terminal, a remote server, or the like as a character code, a numeric code, or a combination thereof. Is. The authentication determination unit 2 determines whether or not the input authentication information is correct with reference to authentication information unique to the mobile terminal A1 and the owner, which is recorded in advance in a database (not shown). .

  The anti-theft management unit 3 outputs a control signal indicating whether or not to release the lock according to the determination result by the authentication determination unit 2. For example, if the input authentication information is not correct, a signal for controlling not to release the lock is output. The lock mechanism control unit 4 generates a control signal for the lock mechanism based on the output signal of the anti-theft management unit 3. The lock device 5 receives the control signal and locks or unlocks the connection between the power supply unit and the power supply unit. For example, when receiving a control signal to be locked from the lock mechanism control unit 4, the lock device 5 locks the connection between the power supply unit and the power supply unit.

  Next, the procedure for performing authentication and locking on the mobile terminal A1 side will be described with reference to the flowchart of FIG. First, when charging the battery built in the portable terminal A1, the power receiving unit of the plug of the portable terminal A1 is inserted into the power supply unit of the outlet on the power supply unit side (step S11). Thereby, charging of the battery is started. Here, it is determined whether or not the connection between the plug and the outlet is to be locked (step S12), and when the lock is to be locked, the lock mechanism is activated (step S13). Note that the procedure of step S12 can be omitted as necessary. During the operation of this locking mechanism, the plug and outlet cannot be disconnected. Therefore, unauthorized removal (theft) of the mobile phone device by a third party can be prevented.

  On the other hand, when the user of the portable terminal A1 intends to release the lock arbitrarily, unique authentication information is input from the authentication input device 1 (step S14). When the authentication information is input, the authentication determination unit 2 determines whether or not the authentication information matches the reference authentication information registered in the database in advance (step S15). If they match, the anti-theft management unit 3 determines that the theft is not theft and inputs a control signal to the lock mechanism control unit 4. Accordingly, the lock mechanism control 4 operates the lock device 5 to release the connection lock between the plug and the outlet (step S16).

  Note that as the authentication information used for the authentication determination, in addition to code information such as symbols, numbers, and characters input from function keys and a keyboard, image pattern information such as the fingerprint and iris of the owner of the mobile terminal A1 is used. be able to. In this embodiment, authentication determination is repeatedly performed until it is determined that the authentication result is correct. However, when the authentication determination exceeds the set number of times, a notification is generated and the process can be terminated without proceeding to the subsequent unlocking step. In addition, when the mobile terminal A1 is locked with the power supply unit, the mobile terminal A1 is automatically changed to the handsfree or answering machine mode so that the mobile terminal A1 is received while the mobile terminal is locked. The convenience of the user at the time can be improved. It is also possible to perform authentication management (Administrator-Guest) according to the unlock level of the user. Furthermore, authentication can be performed by accessing a server (authentication information database) having authentication information via a network.

  Here, the locking device 5 has a mechanism as shown in FIG. 3, for example. In FIG. 3, a pair of power receiving portions (plug blades) 21 and a ground pin 22 projecting from the back surface of the mobile phone T which is the mobile terminal A1 are connected to the mobile phone T main body and the outside of the main body. On the other hand, a power supply unit (contact) connected to the mobile phone T main body and a pin receiving contact are provided on the wall surface of the room. The power supply unit and the pin receiving contact are provided inside one end of the outlet-side long holes 23 and 24, respectively, and are not visible from the outside in the drawing. The power receiving unit 21 and the ground pin 22 can be contacted (connected) to each other by being inserted into the power supply unit and the pin receiving contact through the outlet side long holes 23 and 24, respectively. Further, a lock pin 25 for restricting the release of the connection between the main body of the mobile phone T and the outside of the main body is disposed in the back surface of the mobile phone T at a position close to the ground pin 22 so as to be able to enter and exit. The head of the lock pin 25 normally does not project to the back surface, and functions to project outward from the back surface by energizing a solenoid (not shown) upon receiving a lock command.

  Here, the power receiving unit 21 and the ground pin 22 of the mobile phone T are inserted into the outlet side long holes 23 and 24, respectively, and the mobile phone T is rotated in a vertical plane. As a result, the power receiving unit 21 and the ground pin 22 move in the outlet-side long holes 23 and 24, stop in contact with the power supply unit and the pin receiving contact, and the movement in the pulling direction is restricted. In this state, the solenoid is energized to cause the lock pin 25 to protrude. Accordingly, the lock pin 25 is inserted into the long hole 24 so as to be adjacent to the ground pin 22. The lock pin 25 restricts the movement of the ground pin 22 in the long hole 24, and the movement restriction state in the pulling direction is maintained. Therefore, the power receiving unit 21 and the ground pin 22 are prevented from coming off. When the authentication is correct, the lock pin 25 can be returned to the mobile phone T by deactivating the solenoid by operating the function key. For this reason, by pulling back the mobile terminal in the direction opposite to the rotation direction, the removal direction restriction is released, and the mobile phone T can be removed from the wall outlet.

  FIG. 4 is a conceptual diagram showing another configuration example of the locking device in the mobile terminal of FIG. 1, using a battery adapter of the mobile phone T using a charging adapter (AC / DC converter block) 26 connected to a power cable 25. Indicates what is to be charged. When this charging is performed, the tip end side of the charging adapter 26 (power supply unit) is pushed into a recess 27 provided in the lower part of the mobile phone T. As a result, the hook-shaped locking portions 30 at the ends of the pair of L-shaped links 29 provided in the recesses 27 are engaged with the V-grooves 28 formed on both side surfaces of the charging adapter 26, respectively. Connect the main unit and the outside of the main unit. Since the L-shaped link 29 is urged to rotate about the support shaft 32 by a spring 31, it can be engaged. Further, since the gap between the charging adapter 26 and the concave portion 27 is small on the lower surface of the mobile phone, this engagement cannot be released from the outside, and the locked state will not be removed by fraud. On the other hand, to release this locked state, authentication information is input, and the solenoid 33 is energized only when the authentication is correct. As a result, the L-shaped link 29 connected to the plunger 34 is urged to rotate in the opposite direction. As a result, the hook-shaped locking portion 30 is disengaged from the V-groove 28, and the charging adapter 26 can be easily removed from the recess 27. The spring 31, the spring 32, and the plunger 34 regulate the release of the connection between the mobile phone T main body and the outside of the main body.

  FIG. 5 is a block diagram showing a portable terminal A2 according to another embodiment of the present invention. In this embodiment, the disconnection between the power receiving unit and the power feeding unit is regulated on the power supply unit B side, which is the outlet (adapter) side, according to a command from the portable terminal A2. The portable terminal A2 includes an authentication input device 41, an authentication determination unit 42, an anti-theft management unit 43, a lock operation information output unit 44, and a transmission / reception unit 45.

  Among these, the authentication input device 41, the authentication determination unit 42, and the anti-theft management unit 43 have the same functions as the authentication input device 1, the authentication determination unit 2, and the anti-theft management unit 3 shown in FIG. A duplicate description is omitted. The lock operation information output unit 44 generates and outputs a lock operation signal based on the anti-theft signal output by the anti-theft unit 43 based on the authentication determination result. The transmission / reception unit 45 controls the connection state between the main body outside and the portable terminal A2 main body with respect to the lock device 48 provided outside the main body that regulates the release of the connection between the mobile terminal A2 main body outside and the portable terminal A2. The lock operation signal is transmitted to the power supply unit B by wire or wireless.

  The power supply unit B connected to the portable terminal A2 is attached to the wall surface in the room, and receives and transmits a control signal for controlling the connection state with the portable terminal A2 main body according to the authentication result, and a lock It consists of a mechanism control unit 47 and a lock device 48 that regulates the release of the connection with the mobile terminal A2 main body. Among these, the transmission / reception unit 46 receives the lock operation signal transmitted from the portable terminal A <b> 2 and inputs it to the lock mechanism control unit 47. The lock mechanism control unit 47 receives the lock operation signal and operates the lock device 48 to lock the connection between the plug and the outlet, specifically, the connection between the power supply unit and the power reception unit on the power supply unit B side. It is.

  Next, the operation flow of the portable terminal A2 will be described with reference to FIG. First, the plug of the portable terminal A2 is inserted into the outlet of the power supply unit B (step S51), and connection with a target device (lock target device) compatible with a predetermined communication technology such as Bluetooth is confirmed through the outlet. In this case (step S52), an inquiry is then made as to whether or not to lock (step S53). In the case of locking, the locking device 48 is activated to restrict (lock) the connection state between the plug and the outlet (connection state between the power supply unit and the power reception unit) (step S54). On the other hand, when the lock is to be released in this locked state, the owner of the mobile terminal A2 inputs authentication information from the authentication input device 41 (step S55). The authentication control unit 42 determines whether the reference authentication information registered in advance matches the input authentication information (step S56). If the authentication is correct, the anti-theft management unit 43 The lock operation information output unit 44 outputs a lock release signal. This lock release signal is transmitted to the power supply unit B through the transmission / reception unit 45 (step S57).

  FIG. 7 is a flowchart showing the operation flow of the power supply unit B. In FIG. 7, the power supply unit B determines whether or not the plug-side mobile terminal A2 inserted into the outlet is a lock target device (step S58), and if it is a target device, there is a lock operation request. It is determined whether or not (step S59). When there is a lock operation request, the lock mechanism control unit 47 outputs a control signal to the lock device 48, and the lock device 48 operates the lock mechanism (step S60). Further, it is determined whether or not there is a lock release request (step S61). If there is a lock release request, the lock mechanism is released (step S62). As described above, according to the instruction from the portable terminal A2, the connection between the portable terminal A2 main body and the power supply unit B can be locked and unlocked on the power supply unit B side.

  FIG. 8 is a conceptual diagram illustrating a configuration example of the lock device 48 provided in the power supply unit B. The portable terminal A2 is provided with a power receiving unit 71 (here, only one plug blade is shown) 71 for connecting the portable terminal A2 main body and the outside of the main body. A through hole 72 is provided in the vicinity of the distal end portion of the power receiving unit 71. On the other hand, a substantially U-shaped power supply portion 73 made of an elastic metal plate is disposed in the power supply portion B corresponding to the power supply portion 71, and a protrusion having a small hole 74 on the opposing piece of the power supply portion 73. Each part 75 is formed. One end of the coil spring 76 is fixed to one of the opposing pieces so as to cover the protrusion 75, and a pin 78 with a flange 77 is supported on the other end of the coil spring 76. One end of an arm 79 that can rotate around a support shaft 81 is in contact with the flange 77, and the other end is connected to a plunger of a solenoid 80. A solenoid 78 coupled to the pin 78 with the flange 77, the arm 79, and the plunger regulates the release of the connection between the mobile terminal A2 main body and the outside of the main body.

  In the lock device having such a configuration, as shown in FIG. 8A, the portable terminal A <b> 2 is opposed to the power supply unit B, and the power supply unit 71 is inserted into the power supply unit 73. This insertion is performed until the through-hole 72 is fitted to the protrusion 75 as shown in FIG. In this fitted state, the battery built in the portable terminal A2 is charged from the power supply unit 73 through the power supply unit 71. Further, the through hole 72 and the small hole 74 communicate with each other in this fitted state.

  On the other hand, when the lock command is transmitted from the portable terminal A2 to the power supply unit B by the authentication, the lock device 48 is activated. This operation is performed by turning the solenoid 80 around the support shaft 81 by the bias of the solenoid 80, and by this rotation, the end of the arm 79 pushes the flange 77, and the end of the pin 78 becomes the through hole 72 and the small hole 74. It is an operation that penetrates into. As a result, the power receiving unit 71 is retained and locked in the power supply unit 73. This retaining state is released by releasing the operation of the lock device 48 by inputting authentication information, that is, deactivating the solenoid 80 and returning the pin 78 by the coil spring 76.

  Further, when a charging adapter connected to the power cable is used as the power supply unit B and the locking operation is performed on the charging adapter side, a configuration as shown in FIG. 8 can be adopted. Further, a modular hook (not shown) can be used to perform the locking operation on the charging adapter side. In this case, the pin-shaped return operation blocking member may be locked or released to the modular hook that is locked to the locking notch provided in the portable terminal A2.

  FIG. 9 is a block diagram showing a portable terminal A3 according to another embodiment of the present invention. In this embodiment, the adapter side can be locked on the portable terminal A3 side by a remote command. The portable terminal A3 includes a communication unit 91 that receives an authentication result from the outside, an authentication control unit 92, an anti-theft management unit 93, a lock mechanism control 94, and a lock device 95. The place where the communication unit 91 is provided and the authentication input device is excluded is structurally different from the portable terminal A3 of FIG. The portable terminal A3 is connected to the external device C via a network 96 such as the Internet. The external device C is a mobile phone, a personal computer, or a network server, and includes an authentication input device 97 and a communication unit 98. The external device C is provided with an authentication information database (not shown).

  In a remote place such as a business trip destination, the portable terminal A3 side plug may be inserted into an indoor outlet and the battery may be charged in the locked state as described above. In this case, the user may forget the mobile terminal A3 and go home or notice on the way home, and have an acquaintance, friend, etc. go to get the mobile terminal. At this time, the owner of the mobile terminal A3 inputs predetermined authentication information from the authentication input device 97 of the external device C such as a mobile terminal of an acquaintance or friend or his / her personal computer. This authentication information is transmitted from the communication unit 98 to the portable terminal A3 in the locked state via the network 96.

  As shown in the flowchart of FIG. 10, the portable terminal A3 receives control information related to locking or unlocking together with the authentication information, and analyzes the control information by a control information analysis unit (not shown) (step S101). If the analysis result is a lock request (step S102), it is checked whether the lock is currently being released (step S103). On the other hand, if the analysis result is a lock release request (step S102), it is checked whether or not the lock is currently in progress (step S104). When the lock is being unlocked or locked, the authentication determination unit 92 determines whether the authentication information input from the external device C via the communication unit 91 is correct (steps S105 and S106). When it is determined to be correct, the anti-theft management unit 93 sends a signal indicating that the authentication is successful to the lock mechanism control unit 94, and the lock device 95 performs the operation of the lock mechanism or the operation of the lock mechanism ( Step S107, Step S108). By operating the lock mechanism, it is possible to prevent others from taking away the portable terminal A3 illegally. On the other hand, by releasing the lock mechanism, a friend or acquaintance who came to pick up can deliver the portable terminal A3 to the owner by unplugging the portable terminal A3 from the outlet. Therefore, the portable terminal A3 performs locking or unlocking only when it receives regular authentication information, and can prevent theft. In addition, the control of the lock device using such a network service can employ any receiving method using the network such as SMS (Short Message Service) or E-mail.

  FIG. 11 is a block diagram showing a portable terminal A4 according to still another embodiment of the present invention. In this embodiment, when the lock mechanism is illegally destroyed and another person takes away the portable terminal A4, a notification or alarm is given. The portable terminal A4 includes an authentication input device 111, an authentication determination unit 112, an antitheft management unit 113, a lock mechanism control unit 114, and a lock device 115 similar to those shown in FIG. And a power receiving unit 117 and a power control unit 118. Here, the anti-theft management unit 113 detects an abnormal connection between the main body of the portable terminal A4 and the outside of the main body, and detects the destruction of the lock device 115 or the destruction of the power cable due to the forcible withdrawal of the portable terminal A4. The theft notification signal is output or an alarm is issued. The anti-theft management unit 113 detects a connection abnormality based on voltage fluctuation between the external power supply unit and the power supply unit 117. The theft notification unit 119 receives the theft notification signal from the anti-theft management unit 113, searches the emergency contact database 123 for an emergency contact address, and through the communication unit 120 and the calling unit 121, the security organization, the personal computer of the user terminal, etc. The designated emergency contact 122 is notified of theft. The anti-theft management unit 113, the theft notification unit 119, the communication unit 120, and the calling unit 121 notify the occurrence of a connection abnormality.

  In such a portable terminal A4, as shown in FIG. 12, the anti-theft management unit 113 detects that the voltage supplied to the lock device 115 is at a predetermined normal level (step S131). On the other hand, when the plug and the outlet are connected as described above and there is a request to lock this connection (step S132), the lock is performed by the lock device (step S133). On the other hand, in this locked state, when a third party destroys the lock device 115 or forcibly pulls out the portable terminal A4, the anti-theft management unit 113 detects these fraudulent activities by detecting energization, that is, the lock device 115. Is detected by a change in voltage applied to the power supply or power interruption (step S134).

  If energization is normally sensed, it is determined that there is no destruction or the like, so it is next determined whether or not the authentication is correct (step S135). S136) The lock mechanism is released. On the other hand, when the energization is abnormal, it is determined that there is a theft due to the destruction of the lock device 115 as described above. The theft notification unit 119 notifies the designated emergency contact 122 through the communication unit 120 or the calling unit 121 of the theft, or operates an alarm device (not shown) provided in the portable terminal to alert the surroundings (step) S137). As a result, early discovery of theft and misuse of the portable terminal A4 can be avoided. Further, by issuing an alarm in the vicinity of the mobile terminal A4, it is possible to intimidate a third party who intends to take away the mobile terminal A4. Note that, when an energization abnormality is detected, the operation of the mobile terminal can be restricted, such as stopping the operation of the application of the mobile terminal A4. Thereby, illegal calls, use of electronic money, and the like can be avoided. It should be noted that the operation restrictions can be set in stages, such as stopping the change of stored data, stopping communication functions such as a call function and e-mail, and disabling all operations. It should be noted that the detection of the breakage of the lock device due to the forcible removal of the portable terminal A4 only needs to be able to confirm the voltage level change or the presence or absence of energization. In the present embodiment, the portable terminal A4 limits the operation of the portable terminal by detecting the detection means for detecting the connection abnormality between the portable terminal main body and the outside of the main body, the notification means for notifying the occurrence of the connection abnormality, and the connection abnormality. Although the example which has the restriction | limiting means to perform was demonstrated, you may give these means to an adapter. In this case, the adapter control means detects a connection abnormality and transmits a control signal for restricting the operation of the portable terminal.

  As explained above, restricting the release of the connection between the mobile device main body and the outside of the main body with a plug or adapter when charging the battery, requiring authentication when releasing this connection, and releasing the connection when the authentication is incorrect By not permitting it, it is possible to prevent the mobile terminal from being forcibly removed.

  INDUSTRIAL APPLICABILITY The portable terminal and adapter of the present invention have an effect of preventing forcible removal, and can be used for anti-theft technology for portable terminals.
