  However, in the safe deposit box as described above, when the memory key is issued to each user, the user may forget to return the memory key and take it home as it is.

  In this case, the user can enter the safe room next time without issuing the card reader, which causes a security problem.

  Therefore, the present invention provides a technology capable of restricting the use of a safe with an authentication key in a safe system in which the user issues an authentication key to allow the user to use the safe except when the authentication key is issued. For the purpose.

  A first aspect of the present invention is a safe system in which an authentication key is issued to a user so that the user can use the safe, and has a storage unit that stores an identification code for authentication when issuing, An authentication key capable of performing an authentication operation to give an identification code to the outside, a safe room having an input / output unit, a safe provided in the safe room, and authentication according to the authentication operation of the authentication key in the vicinity of the input / output unit Recognizing an identification code for authentication given to the key, and entering / exiting control means for controlling opening / closing of the entrance / exit based on the identification code for authentication, and the authentication key is set in advance The authentication operation is performed within the authentication possible time.

  In this case, the authenticable time may be a time from when the identification code is stored in the authentication key until a predetermined time elapses.

  In addition, the authentication key may be in a state where the authentication operation is disabled by deleting the identification code after the authenticable time has elapsed.

  The second aspect of the present invention is an authentication key used in a safe system in which an authentication key is issued to a user and the user is allowed to use the safe using the authentication key. A storage unit that stores an identification code and a control unit that performs an authentication operation that gives the identification code to the outside are provided, and the control unit performs the authentication operation within a preset authenticable time.

  According to the safe system of the present invention, the authentication key performs the authentication operation within a preset authenticable time. Therefore, outside the authenticable time, the safe is used by entering the safe room using the authentication key. Can not be. Therefore, it is possible to restrict use of the safe by the authentication key except when the authentication key is issued.

  In this case, if the authentication possible time is a time from when the identification code is stored in the authentication key to a time after a preset time has elapsed, for example, the identification code is written in the authentication key when the authentication key is issued. Thereafter, the authentication operation can be performed for a preset time.

  Further, the authentication key can be deleted by deleting the identification code after the elapse of the authenticable time, so that the authentication key itself is in an incapable state, thereby eliminating the information related to the identification code in the authentication key itself.

  In addition, according to the authentication key of the present invention, the authentication operation is performed within a preset authenticable time, so that the safe cannot be used using the authentication key outside the authenticable time. Therefore, it is possible to restrict use of the safe by the authentication key except when the authentication key is issued.

  Then, when the user sets the electronic key 70 in the exit card reader 50 or the entrance card reader 55, an authentication start command is given to the electronic key 70. In response to this, a signal including an identification code for authentication is transmitted from the electronic key 70. This signal is received by the exit card reader 50 or the entrance card reader 55, and the identification code is transmitted to the computer main body 32. Then, the computer main unit 32 refers to the customer management data to determine whether or not the identification code can be authenticated. If the identification code is incompatible, the locked state by the door lock mechanism 52 is maintained. . On the other hand, in the case of authentication conformity, the locked state by the door lock mechanism 52 is released and the unlocked state is set.

  In the present embodiment, the combination of the key issuing control device 30, the door lock mechanism, and the entrance card reader 55 is used for authentication given to the electronic key 70 in accordance with the authentication operation of the electronic key 70 in the vicinity of the entrance / exit portion 11. The entrance monitoring control means for recognizing the identification code and controlling the opening / closing of the entrance / exit portion 11 based on the identification code for authentication is configured.

<Safety device>
The electronic key 70 and the safe deposit key 18 will be described.

  FIG. 3 is a front view showing the safe apparatus, and FIG. 4 is a block diagram showing an electrical configuration of the safe apparatus.

  The safe apparatus includes a safe 20 having a safe door 22, a cover lock 60 attached to the safe door 22, and an electronic key 70.

  The safe 20 includes a safe main body having a storage space and a safe door 22 attached to the opening of the storage space so as to be freely opened and closed. A safe lock 23 for locking or unlocking the safe door 22 by a mechanical mechanism is incorporated in the safe door 22. The keyhole 23h of the safe lock 23 is formed so as to open on the front side of the safe door 22, and the safe lock 23 is locked by inserting the safe lock key 18 into the keyhole 23h and turning it in a predetermined direction. Or unlocked.

  The cover lock 60 receives power from the electronic key 70 side, and performs the collating operation of the electronic key 70 and the operation of enabling the safe lock 23 to be exposed. Here, exposing the safe lock 23 means exposing a portion of the safe lock 23 that needs to be accessed from the outside for unlocking and locking. In the form, it means that the keyhole 23h is exposed.

  More specifically, the cover lock 60 includes a base member 61, a cover member 62, a locking mechanism 64, a transmission / reception unit 65, a safe-side control unit 66, and a power reception unit 68.

  The base member 61 is fixed to the surface side of the safe door 22 so as not to be removable, and supports the cover member 62 so as to be movable. The base member 61 has a hole 61 h for exposing the key hole 23 h to the outside.

  The cover member 62 is supported so as to be reciprocally movable along the arrow A direction in FIG. 3 with respect to the base member 61, and an exposure position where the key hole 23h in the hole 61h can be exposed (see FIG. 3). And the shielding position where the keyhole 23h can be shielded. The cover member 62 is provided with a set portion 63 on which the electronic key 70 can be set. The electronic key 70 is slid in the direction indicated by the arrow B in FIG. Set to

  The locking mechanism 64 is a mechanism for locking or unlocking the cover member 62, and receives power from the power supply unit 76 of the electronic key 70 to drive the solenoid 64 a, thereby engaging the cover member 62 side. The cover member 62 is locked (unmovable) or unlocked (movable) by engaging and disengaging the portion (not shown) and the engaging portion (not shown) on the base member side.

  The transceiver unit 65 is configured by a combination of a light emitting element such as a light emitting diode and a light receiving element such as a photodiode. By setting the electronic key 70 in the setting unit 63, bidirectional optical communication is possible between the main transmission / reception unit 65 and the transmission / reception unit 72 on the electronic key 70 side.

  The power receiving unit 68 includes a pair of terminals exposed to the outside. Then, by setting the electronic key 70 in the setting unit 63, an electrical connection is made between the power receiving unit 68 and the power supply unit 78 on the electronic key 70 side, and the power source unit 76 to the safe side control unit 66. In addition, the power supply path to the solenoid 64a can be established. Note that a configuration in which contactless power feeding is performed from the power feeding unit 78 to the power receiving unit 68 may be employed.

  The safe-side control unit 66 is configured by a general microcomputer including a CPU, a ROM, a RAM, and the like, and all the arithmetic operations are elements executed by a software program stored in advance. The safe-side control unit 66 has an ID storage unit 66 a that stores a unique identification code. When the electronic key 70 is set in the setting unit 63, bidirectional optical communication with the electronic key 70 is performed. To determine whether or not the identification code for authentication included in the signal received through the transmission / reception unit 65 matches its own unique identification code, and to the solenoid 64a when both codes match. The switch portion 65b inserted in the power feeding circuit is turned on, the solenoid 64a is driven, and the cover member 62 is unlocked. In other cases, the switch portion 65b is turned off and the cover member 62 is locked.

  The electronic key 70 has a substantially rectangular plate-like appearance, and includes a transmission / reception unit 72, a key-side control unit 74, a power supply unit 76, a power feeding unit 78, and light emitting units 79a to 79c. Yes.

  The transmission / reception unit 72 is configured by a combination of a light emitting element such as a light emitting diode and a light receiving element such as a photodiode. By setting the electronic key 70 in the setting unit 63, bidirectional optical communication is possible between the main transmission / reception unit 65 and the transmission / reception unit 72 on the electronic key 70 side. In the state where the electronic key 70 is set in the electronic key issuing box 38, bidirectional optical communication is performed between the transmitting / receiving unit 72 and the transmitting / receiving unit in the electronic key issuing box 38. Further, even when the electronic key 70 is set in the entry card reader 55 or the exit card reader 50, bidirectional optical communication is performed between the transmission / reception unit 72 and the transmission / reception unit in the entrance card reader 55 or the exit card reader 50.

  The power source unit 76 is a rechargeable battery and functions as a power source for the key side control unit 74, the light emitting units 79a to 79c, and the safe side control unit 66 and the solenoid when the electronic key 70 is set in the set unit 63. 64a functions as a power source. Note that a general primary battery may be used as the power supply unit 76. In this case, charging in the electronic key issuing box 38 is not necessary.

  The power feeding unit 78 is composed of a pair of terminals exposed to the outside. Then, by setting the electronic key 70 to the setting unit 63, the power feeding unit 78 and the power receiving unit 68 are electrically connected. In the state where the electronic key 70 is set in the electronic key issuing box 38, the power feeding unit 78 is electrically connected to the charging terminal, and the power source unit 76 is charged.

  The light emitting units 79a to 79c are composed of light emitting elements such as light emitting diodes, and display various states associated with the unlocking and locking of the safe 20 according to the issuing mode based on the control of the key side control unit 74. For example, when the light emitting unit 79a is turned on, a guidance display is displayed indicating that the authentication identification code is registered in the electronic key issuing box 38, and when the light emitting unit 79b is turned on, the electronic key 70 is set in the setting unit 63. It is displayed and whether the authentication in the safe-side control unit 66 is compliant or non-compliant is indicated by lighting and blinking of the light emitting unit 79b.

  The key-side control unit 74 is configured by a general microcomputer including a CPU, a ROM, a RAM, and the like, and all the arithmetic operations are elements executed by a software program stored in advance, and perform the following operations. The key-side control unit 74 includes an authentication ID storage unit 74a that stores an identification code for authentication in a rewritable manner.

  FIG. 5 is a flowchart showing the operation of the electronic key 70.

  That is, in step S1, the key-side control unit 74 determines whether or not there is an authentication identification code write command. Here, when it is determined that there is a write command, the process proceeds to step S2, in which an authentication identification code is written into the authentication ID storage unit 74a, and counting from the time when the writing is performed is started. Usually, with the electronic key 70 set in the electronic key issuing box 38, the identification code is written to the electronic key 70 at a predetermined timing.

  Next, in step S3, it is determined whether or not the time t counted from the time when the identification code is written has passed the authenticable time T. Here, the authenticable time T is a predetermined time set in advance, for example, set to a time (for example, 2 hours) that allows the user to have a normal time to use the safe deposit box. If it is determined that the authenticable time T has elapsed, the process proceeds to step S7, the identification code in the authentication ID storage unit 74a is deleted, the authentication operation is disabled, and the process ends. Note that, as long as there is no hindrance to the operation of the electronic key 70, the step of determining whether or not the measured time t has passed the authenticable time T is performed at any timing (for example, before step S6 to be described later). May be.

  On the other hand, if it is determined in step S3 that the authentication possible time T has not elapsed, the process proceeds to step S4, and the presence / absence of an authentication start command is determined. If it is determined that there is an acceptance start command, the process proceeds to step S5, and an identification code for authentication is transmitted. This operation is an authentication operation for giving an identification code to the outside. Normally, the authentication operation is performed with the electronic key 70 set in the entrance card reader 55 or the exit card reader 50 and the setting unit 63.

  When it is determined in step S4 that there is no authentication start command, and after the authentication operation is performed in step S5, the process proceeds to step S6, where it is determined whether there is an authentication identification code deletion command. Here, if it is determined that there is no erasure command, the process returns to step S3 and the processes in and after step S3 are repeated. On the other hand, if it is determined in step S6 that there is an erasure command, the process proceeds to step S7, where the identification code in the authentication ID storage unit 74a is erased to make the authentication operation impossible, and the process ends. Usually, with the electronic key 70 set in the electronic key issuing box 38, the identification code erasure process through steps S6 and S7 is performed.

  FIG. 6 is a flowchart showing the operation of the safe apparatus including the electronic key.

  First, in step S <b> 10, the electronic key 70 issued by the user is set in the setting unit 63.

  As a result, in step S11, power supply from the power supply unit 76 of the electronic key 70 to the cover lock 60 side is started, and a set state indicating that the electronic key 70 is normally set is displayed by the light emitting units 79a to 79c.

  Subsequently, in step S12, optical communication is performed between the electronic key 70 and the cover lock 60, an authentication start command is given to the electronic key 70, and the authentication identification registered in the electronic key 70 in response to this is given. The code is transmitted to the cover lock 60. In step S13, the safe-side control unit 66 determines whether or not the ID verification, that is, the identification code for authentication matches the unique identification code. As a result, if the authentication is incompatible, the process proceeds to step S18, and the light emitting units 79a to 79c indicate that the authentication is incompatible.

  On the other hand, if the authentication result is appropriate, the process proceeds to step S14. In step S14, the safe-side control unit 66 turns on the switch unit 65b to bring the locking mechanism 64 into the unlocked state for a predetermined time (for example, about several tens of seconds), and the light emitting units 79a to 79c are in an authentication conformity state. A message is displayed. As a result, the cover member 62 is movable to the exposure position.

  Thereafter, as shown in step S15, the user moves the cover member 62 to the exposed position, inserts the safe lock key 18 into the key hole 23h, rotates it in a predetermined direction, and unlocks the safe lock 23. . Then, the safe door 22 is opened, and desired articles are stored and taken out.

  When the operation on the safe 20 is completed, as shown in step S16, the user closes the safe door 22, then rotates the safe key 18 to lock the safe lock 23, and the safe key 18 is removed from the keyhole 23h. Pull out. Then, the cover member 62 is moved to the shielding position.

  Finally, as shown in step S17, the electronic key 70 is removed from the setting unit 63, and the operation ends.

<Explanation of the entire safe system>
A normal usage pattern of the safe system will be described with reference to FIG.

  When the user uses the safe system, as shown in step S20, the user signs up at the reception desk 13 and applies for the use of the safe. In step S21, it is confirmed that the bank clerk is a legitimate user, and the key issuing control device 30 is operated to issue the electronic key 70 in which a predetermined authentication identification code is written. In addition, a user list that is prohibited from use is generated on the key issuance control device 30 side, and when the electronic key 70 is issued, the user list is referred to and a person who is prohibited from use is referred to. Therefore, it is preferable that the electronic key 70 cannot be issued.

  The user receives the electronic key 70 and moves to the entrance card reader 55. In step S22, the electronic key 70 is set in the entrance card reader 55. Then, an authentication start command is given to the electronic key 70 from the entrance card reader 55, and in response to this, the electronic key 70 performs an authentication operation and transmits an identification code for authentication. This identification code for authentication is given from the entrance card reader 55 to the computer main body 32, and the computer main body 32 refers to the customer management data and authenticates the identification code. Here, in the case of non-authentication, the door lock mechanism 52 is kept locked and cannot enter the safe room 10. Normally, it is determined that the authentication conforms, and the door lock mechanism 52 is unlocked, so that the user can enter the safe room 10 from the entrance / exit section 11. When the user enters the safe room 10, the entrance / exit door 11a is locked. In step S23, as described above, the safe 20 assigned to a predetermined self is used using the electronic key 70 and the safe deposit key 18.

  Thereafter, the user moves to the exit card reader 50, sets the electronic key 70 on the exit card reader 50, and authenticates the electronic key 70 as shown in step S24. Here, in the case of non-authentication, the locked state of the door lock mechanism 52 continues. Normally, it is determined that the authentication is suitable, the entrance door 11a is unlocked, and the user can exit the safe room 10 through the entrance / exit section 11. When the user leaves the safe room 10, the entrance / exit door 11a is locked.

  When the user leaves the safe room 10, the user moves to the reception desk 13 and accepts the use end as shown in step S25. In step S26, the bank clerk collects the electronic key 70, sets it in the electronic key issuance box 38, and deletes the identification code for authentication.

  The above is a normal usage form of the safe system. However, when the user has left the forgotten end of use (step S25), that is, when the electronic key 70 is taken home. It will be as follows.

  That is, even when the user takes home the electronic key 70, if the time t from the time when the identification code is written to the electronic key 70 passes the predetermined authenticable time T, the authentication key Delete the identification code.

  As a result, the electronic key 70 that has been taken home is disabled. Therefore, the user cannot enter the safe room 10 using the electronic key 70 that has been taken home.

  If the reception counter 13 returns the electronic key 70 after the elapse of the authenticable time T, when the bank clerk collects the electronic key 70 and sets it in the electronic key issuance box 38, the key issuance control device 30 receives the electronic key 70. It is preferable to display the fact that the authenticable time T has been exceeded and the excess period.

  According to the safe system and the electronic key 70 configured as described above, the electronic key 70 performs an authentication operation for transmitting an identification code in response to an authentication start command within a preset authenticable time T. Outside the authenticable time T, the user cannot enter the safe room 10 using the electronic key 70 and use the safe 20. Therefore, it is possible to restrict use of the safe by the electronic key 70 except when the electronic key 70 is issued (in this embodiment, after the authentication time T has elapsed since the identification code was written to the electronic key 70), thereby improving security. Can be achieved.

  In this embodiment, the authenticable time T is based on the time when the identification code is written (stored) as a reference until after a preset time has elapsed, but it is not always necessary to do so. For example, when the electronic key 70 is set in any of the entrance card reader 55, the exit card reader 50, and the setting unit 63, or when the authentication operation is performed in a state in which the electronic key 70 is set in any of them, the predetermined time is set. It is good also as authentication possible time T until after progress.

  However, by setting the authentication possible time T as in the present embodiment, the authentication operation can be performed for a preset time after the identification code is written in the authentication key when the authentication key is issued. The time when 70 can be used can be set relatively appropriately.

  In this embodiment, the identification code stored in the authentication ID storage unit 74a is erased to disable the authentication operation. However, this is not necessarily required. For example, after the authentication possible time T has elapsed, the identification code may be operated so as not to be transmitted in response to the authentication start command in a state where the identification code is stored in the authentication ID storage unit 74a.

  However, as in the present embodiment, by deleting the identification code stored in the authentication ID storage unit 74a and making the authentication operation impossible, information regarding the identification code can be eliminated in the electronic key 70 itself. In this respect, security is improved.

  In this embodiment, the electronic key 70 performs optical communication with the electronic key issuing box 38, the entrance card reader 55, the exit card reader 50, and the cover member 62. Wired communication may be performed via a wireless communication, or radio wave communication may be performed.
