  The shielding lock unit 40 is configured to release the lock of the shielding member 30 in accordance with the control of the lock side control unit 54.

  As the shielding lock portion 40, the solenoid 44 (see FIG. 5) is driven to engage and disengage the engaged portion (not shown) on the shielding member 30 side and the engaging portion on the apparatus body 22 side. The structure which makes the shielding member 30 an unlocked state (state which can be moved from the shielding position) is employ | adopted. As for the mechanism to return to the locked state, for example, once the electronic key 60 is removed from the set unit 42 after being brought into the unlocked state, the locked state (cannot be moved from the shield position) due to a mechanical biasing force such as a spring. A mechanism that returns to the normal state). It should be noted that a mechanism for returning to the locked state by driving an actuator such as the solenoid 44 at a predetermined timing (for example, when the shielding member 30 is closed) may be employed.

  Further, here, the solenoid 44 is configured to be driven by receiving power supply from the electronic key 60 via the power receiving terminal 42 a of the set unit 42 provided in the apparatus main body 22. Of course, as the shielding lock unit 40, various other configurations that can be locked and unlocked using an actuator can be adopted.

  The lock side control unit 54 is configured by an electronic circuit including a microcomputer chip or the like, and is incorporated in the device main body 22 in the form of a control board. The lock-side control unit 54 operates by receiving power supply from the electronic key 60 via the power receiving terminal 42a. Further, the lock side control unit 54 communicates with the electronic key 60 via the communication unit 42b provided in the setting unit 42, executes predetermined arithmetic processing described later, and controls driving of the solenoid 44 and the like. It has become.

  The electronic key 60 is for unlocking the lock device 20 by electronic authentication, and is formed in a shape that can be set in the set portion 42, here, a substantially rectangular plate shape.

  FIG. 5 is a block diagram showing the electrical configuration of the lock device and the electronic key.

  That is, the electronic key 60 includes a key side control unit 62, a storage unit 63, and a power source 64.

  The key-side control unit 62 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 key control unit 62 incorporates a storage unit 63 that stores authentication information.

  When the electronic key 60 is set in the setting unit 42, the key-side control unit 62 communicates with the lock-side control unit 54 via the communication unit 65 and performs authentication while referring to the authentication information. A predetermined process is executed. The key-side control unit 62 includes a timer circuit, and writes a usage history to the storage unit 63 at a predetermined timing described later. Note that the storage unit 63 may be configured separately from the key side control unit 62.

  The power source 64 is a rechargeable battery and functions as a power source for the key side control unit 62 and the like. When the electronic key 60 is set in the key issuing machine 80, the power source 64 is charged. In the state where the electronic key 60 is set in the setting unit 42, power is supplied from the power source 64 to the side of the lock device 20 through the power supply terminal 66 and the power reception terminal 42 a.

  The lock device 20 includes a lock side control unit 54 and a storage unit 55. The lock side control unit 54 is configured by a general microcomputer including a CPU, a ROM, a RAM, and the like, and all of the calculation operations are elements executed by a software program stored in advance. The lock side control unit 54 incorporates a storage unit 55 that stores predetermined information necessary for the authentication operation. When the electronic key 60 is set in the setting unit 42, communication is performed with the electronic key 60, and a predetermined process related to authentication is executed. When the authentication result is available, the switch unit 56 is temporarily turned on so that the solenoid 44 can be energized. The storage unit 55 may be configured separately from the lock side control unit 54.

  The locking device 20 includes an open / close sensor 28. The open / close sensor 28 is a sensor that detects the open / closed state of the doors 12a, 12b and the drawer portion 14, and includes an optical sensor, a microswitch, and the like. The detection result of the open / close sensor 28 is given to the key control unit 62 via the lock control unit 54.

  When the electronic key 60 is set on the setting unit 42, power is supplied from the power source 64 to the lock side control unit 54 via the power supply terminal 66 and the power receiving terminal 42a. Communication is performed between the key-side control unit 62 and the lock-side control unit 54 of the electronic key 60 via the communication units 42 b and 65. Here, the communication is performed by radio wave communication, optical communication, or the like, and is preferably performed by wireless communication applied to FeliCa or the like. Then, by performing communication between the key side control unit 62 and the lock side control unit 54, a predetermined authentication operation is performed regarding whether or not the storage shelf 10 can be used.

  Various well-known methods can be adopted as the authentication processing here, but one of them is the following processing. That is, in the storage unit 63 of the key-side control unit 62, as authentication information, for each user identification number (B0000, B0001, B0002, B0003,...) For identifying each user, as shown in FIG. A table specifying the position specifying number (A0000, A0001, A0002, A0003,...) Specifying the position of the storage units 11a, 11b, 11c, and 11d and the availability information is written. That is, here, since a storage system in which a plurality of storage positions and a plurality of users are assumed is assumed, information that sets availability of each storage position for each user is stored as authentication information. When the electronic key 60 is issued from the key issuing machine 80, the user is specified and specific information is given to the electronic key 60. The storage unit 55 of the lock side control unit 54 stores a position identification number. When the electronic key 60 is set in the setting unit 42, the position specifying number of the storage shelf 10 is given from the lock side control unit 54 to the key side control unit 62. Thus, the key side control unit 62 stores the lock side control unit 54 on the basis of the table, the user specifying information given in advance, and the position specifying number given from the lock side control unit 54. It is determined whether or not the units 11a, 11b, 11c, and 11d can be used. When it is determined that use is possible, a use permission command is given to the lock control unit 54. In response to this command, the lock side control unit 54 controls the drive of the solenoid 44 to set the lock release state so that the shielding member 30 can be opened. Thereafter, the solenoid 44 is driven and controlled, and the shielding member 30 is brought into the locked state.

  Note that, for example, authentication information may be given from the key-side control unit 62 to the lock-side control unit, and the lock-side control unit 54 may determine whether it can be used. In short, it is possible to employ various authentication operations for determining whether or not the key can be used through communication between the key side control unit 62 and the lock side control unit 54 based on the authentication information stored in the storage unit 63 on the electronic key 60 side. .

<Key issuing machine>
As shown in FIG. 1, the key issuing machine 80 has a setting unit 81 for setting the electronic key 60, and issues the electronic key 60 to the user.

The charging unit 83 charges the power source 64 of the electronic key 60 set in the setting unit 81 via the charging terminal 82a. The key issuance lock unit 84 is configured to lock or unlock the electronic key 60 set in the set unit 81 so that it cannot be removed under the control of the key issuance control unit 90. Such a key issuance lock unit 84 is realized by, for example, a mechanism for driving and controlling an engagement mechanism that is detachable from the electronic key 60 set in the set unit 81 by an actuator such as a solenoid.

  The key issuance control unit 90 includes an issuance control unit 92 and a numeric keypad 94. The issuance control unit 92 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 key issuance control unit 90 includes a storage unit 93. The storage unit 93 includes information for identifying an individual, here, each user and a personal identification number assigned to each user. Is stored in the specific information table. The numeric keypad 94 is an input means for the user to input a password. When the user inputs a personal identification number through the numeric keypad 94, the key issuance control unit 90 determines whether the user is an authorized user based on the input personal identification number and the specific information table. Identify users. And the information regarding the specified user is given to the electronic key 60 set to the setting part 81 through the communication part 81b. Thereafter, the key issuance lock unit 84 is controlled to release the lock.

  Here, the key issuing control unit 90 functions as a user specifying means for specifying a user. The key issuance control unit 90 identifies a user by inputting a personal identification number through the numeric keypad 94 as described above, and reads and authenticates an ID card (for example, felica) with a reader (for example, a personal computer), a fingerprint, a vein, The user specifying unit may be configured by adding a biometric authentication device such as a voice or adopting it as an alternative unit.

  Further, the configuration as the user specifying means may be incorporated in the electronic key 60 itself. Further, the key issuance lock unit 84 and the key issuance control unit 90 communicate with each other by a wireless system such as a wireless LAN so that both can be installed separately, and the key issuance lock unit 84 is stored in the storage shelf 10 itself. You may make it attach to.

<Description of operation>
FIG. 8 is a flowchart showing the operation of the key issuing machine.

  That is, the operation of issuing and collecting the electronic key 60 in the key issuing machine 80 is performed as follows.

  In the initial state, the electronic key 60 is set in the setting unit 81 of the key issuing machine 80, and the electronic key 60 cannot be removed by the lock of the key issuing lock unit 84.

  In this state, as shown in step S1, when a personal identification number is input through the numeric keypad 94, whether or not the personal identification number matches in the next step S2 based on the input personal identification number and the specific information table. Is determined. If the passwords do not match, the process ends. If the passwords match, the process proceeds to step S3, where the user identification information is given to the electronic key 60, and the key issuance lock unit 84 is locked. Set to the release state. As a result, the electronic key 60 can be removed from the set unit 81 and removed, and the user can use the storage system by holding the electronic key 60.

  Thereafter, in step S4, it is determined whether or not the electronic key 60 has been returned. This determination is made in the issuance control unit 92 based on, for example, a detection output from a contact sensor or the like provided in the set unit 81. Until the electronic key 60 is returned, the process of step S4 is repeated. When the electronic key 60 is returned, the process proceeds to step S5.

  In step S5, the key issuance lock unit 84 is locked. As a result, the electronic key 60 is prevented from being removed from the set unit 81. As a result, the user returns the electronic key 60 to the key issuing machine 80 and ends the use of the storage system.

  FIG. 9 is a flowchart showing the operation of the electronic key.

  That is, the electronic key 60 is issued to the user through the above issuing operation.

  First, in step S <b> 11, it is determined whether or not the electronic key 60 is set in the setting unit 42 of the lock device 20. The process of step S11 is repeated until the electronic key 60 is set in the setting unit 42. When the electronic key 60 is set in the setting unit 42, the process proceeds to the next step S12.

  In step S12, communication is performed between the lock side control unit 54 and the key side control unit 62 to perform the authentication process as described above, and the process proceeds to step S13.

  If it is determined in step S13 that the service is not available as a result of the authentication process, the process ends. On the other hand, if it is determined that it can be used, the process proceeds to step S14, an unlock command is given to the lock side control unit 54, and the process proceeds to the next step S15.

  In step S15, it is determined whether or not the doors 12a, 12b or the drawer portion 14 are opened. This determination is made based on the detection result from the open / close sensor 28. And the process of step S15 is repeated until an open state is detected, and when an open state is detected, it will progress to step S16.

  In step S16, the key side control unit 62 writes the usage history in the storage unit 63, and proceeds to the next step S17.

  In step S17, it is determined whether or not the doors 12a, 12b or the drawer portion 14 are closed. This determination is made based on the detection result from the open / close sensor 28. And the process of step S17 is repeated until a closed state is detected, and when a closed state is detected, it will progress to step S18.

  In step S <b> 18, the key side control unit 62 writes the use history in the storage unit 63. Then, the process ends.

  The usage history written in the storage unit 63 is information (for example, the position identification number in FIG. 6) that identifies the storage units 11a, 11b, 11c, 11d, etc. (or the locked locking device 20). , Information for identifying the user (for example, the user identification number in FIG. 6), information on the content of the utilization (for example, whether the doors 12a, 12b or the drawer 14 are opened or closed), and time information, In addition, the information is associated with each other. The usage history may include at least one of these pieces of information.

  FIG. 10 is a flowchart showing the operation of the lock device.

  First, in step S21, it is determined whether or not the electronic key 60 is set. Step S21 is repeated until the electronic key 60 is set. Then, when the user sets the electronic key 60 in the setting unit 42 of the lock device 20 and it is determined that the electronic key 60 is set, the process proceeds to the next step S22.

  In step S22, communication is performed between the lock side control unit 54 and the key side control unit 62 to perform the authentication process as described above, and the process proceeds to step S23.

  In step S23, it is determined whether or not there is an unlock command. If there is no unlock command, the process ends. On the other hand, when the unlocking command is given from the key-side control unit 62, the shielding lock unit 40 is brought into the unlocked state. Thereby, the shielding member 30 of the shielding lock part 40 will be in the openable state. Thus, the user can use one of the storage portions 11a, 11b, 11c, 11d and the like by opening the doors 12a, 12b and the drawer portion 14 by opening the shielding member 30.

  After step S23, the process proceeds to step S24. In step S24, the shielding lock part 40 is brought into a lockable state by controlling the solenoid 44. Thereby, when the shielding member 30 is closed, the shielding member 30 is locked in a closed state, and the shielding lock portion 40 is locked. The process ends as described above.

Then, the authentication process is performed between the electronic key 60 and the lock device 20, and when it is determined that the electronic key 60 and the lock device 20 can be used, the lock device 20 is unlocked. Thereby, the user can use the desired storage portions 11a, 11b, 11c, and 11d by opening the shielding member 30 of the lock device 20.

  When the use is finished, the user closes the shielding member 30 and removes the electronic key 60 from the setting unit 42. Then, the lock device 20 is locked. Thereafter, the user moves again to the key issuing machine 80, sets the electronic key 60 in the setting unit 81 of the key issuing machine 80, and ends the use.

  The usage history stored in the electronic key 60 can be appropriately read through a management personal computer or the like and displayed on the display means of the personal computer.

<Summary>
According to the storage system configured as described above, in the storage system in which the lock device 20 and the electronic key 60 communicate with each other to perform an authentication operation and are determined to be usable, the lock device 20 is unlocked. The lock device 20 is configured to store a use history related to the storage units 11a, 11b, 11c, 11d, and the like. For this reason, it is possible to appropriately manage the usage status of the storage units 11a, 11b, 11c, 11d and the like, which is very effective for information security measures.

  The usage history may be written on the lock device 20 side. However, writing the usage history on the electronic key 60 side has advantages that, for example, it is easier to manage the history with a management personal computer or the like, and management can be performed in units of the electronic key 60.

  Further, as the use history, various histories using the storage units 11a, 11b, 11c, 11d and the like using the electronic key 60 can be considered.

  In particular, in the present embodiment, the electronic key 60 includes the timing at which the doors 12a, 12b or the drawer portion 14 are opened as the use start timing of the storage units 11a, 11b, 11c, 11d, and the storage units 11a, 11b. , 11c, 11d, etc., because the use history is stored at the timing when the closed state of the doors 12a, 12b or the drawer portion 14 is detected as the use end timing. By leaving them as, you can manage their usage more appropriately.

  It should be noted that the usage history may be left at only one of the usage start timing and the usage end timing. Further, as the use start timing and use end timing, in addition to the timing according to the open / closed state of the doors 12a, 12b or the drawer portion 14, the drive timing of the solenoid 44, the open / close detection timing of the shielding member 30, and the electronic key 60 are set to the set portion 42. It may be a timing according to at least one of the timings of insertion and removal.

  In addition to the use start timing and use end timing as described above, the electronic key 60 stores the issuance and return history at the timing issued from the key issuing machine 80 and the timing returned to the key issuing machine 80. You may make it do.

  Further, the user is specified by the key issuance control unit 90, the user specifying information is given to the electronic key 60, and the electronic key 60 is used to store a usage history including information regarding the specified user in the storage unit. Therefore, even when the electronic key is shared by a plurality of users, the usage history can be managed for each user.

  However, in the case where the electronic key 60 is issued individually for each user, each electronic key 60 stores the usage history of the electronic key 60 without specifying the user. Eventually, the usage history of the electronic key 60 can be managed for each electronic key 60, that is, for each user.

{Modification}
FIG. 11 is a perspective view showing a storage system according to a modification, and FIG. 12 is a block diagram showing an electrical configuration of a lock device, an electronic key, and a stored item retrieval apparatus according to the modification.

  The storage system according to this modification further includes a stored item retrieval apparatus 100 that retrieves a stored item stored in the storage unit 11a as a storage unit.

  The stored item search device 100 includes a tag device 110 and a communication unit 112, and the key side control unit 62B functions as a search control unit.

  The tag apparatus 110 is an apparatus assigned with an identification code corresponding to the stored item 111, and is attached to each of the stored items (for example, a file in which a document is closed). The communication unit 112 is attached to the inside of the door 12a, for example, and can communicate with each tag device 110 attached to the stored item 111 in the storage unit 11a. Here, the tag device 110 and the communication unit 112 perform communication using an optical signal. Of course, a communication format using radio waves or the like may be used.

  Then, in a state where the electronic key 60B is set in the set unit 42 of the lock device 20B, the key side control unit 62B as a search control unit is connected to each tag device 110 via the lock side control unit 54 and the communication unit 112. Communicate between the two. Thereby, it is comprised so that the inventory condition (situation at least including the presence or absence of inventory) of the stored item 111 accommodated in this accommodating part 11a can be recognized.

  For example, the technology disclosed in Japanese Patent Application Laid-Open No. 2004-359459 can be applied to the stored item retrieval apparatus 100 itself.

  The communication unit 112 is also connected to the power receiving terminal 42a of the set unit 42 in the lock device 20B. The communication unit 112 is configured to receive power supply for optical communication (particularly for emitting an optical signal) from the power source 64 of the electronic key 60B set in the setting unit 42 via the lock device 20B. Has been.

  FIG. 13 is a flowchart showing the operation of the electronic key in the storage system according to the modification.

  That is, after the electronic key 60B is issued to the user, first, in step S31, it is determined whether or not the electronic key 60B is set in the setting unit 42 of the lock device 20. The process of step S31 is repeated until the electronic key 60B is set in the setting unit 42. When the electronic key 60B is set in the setting unit 42, the process proceeds to the next step S32.

  In step S32, communication is performed between the lock side control unit 54 and the key side control unit 62B to perform an authentication process, and the process proceeds to step S33.

  If it is determined in step S33 that the authentication process cannot be used, the process ends. On the other hand, if it is determined that use is possible, the process proceeds to step S34, an unlock command is given to the locking device 20B side, and the process proceeds to the next step S15.

  In step S35, it is determined whether or not the door 12a has been opened. This determination is made based on the detection result from the open / close sensor 28. And the process of step S35 is repeated until an open state is detected, and if an open state is detected, it will progress to step S36.

  In step S <b> 36, the key-side control unit 62 </ b> B communicates with each tag device 110 via the communication unit 112 to search for the inventory status of the stored items 111. Then, it progresses to step S37, writes a utilization history in the memory | storage part 63, and progresses to next step S38. The usage history here includes the inventory status of the stored items 111 in addition to the information described in the above embodiment.

  In step S38, it is determined whether or not the door 12a is closed. Then, the process of step S38 is repeated until the closed state is detected, and when the closed state is detected, the process proceeds to step S39.

  In step S39, the key-side control unit 62B communicates with each tag device 110 via the communication unit 112, and searches the inventory status of the stored items 111. Then, it progresses to step S40, writes a utilization history in the memory | storage part 63, and complete | finishes a process. The usage history here includes the inventory status of the stored items 111 in addition to the information described in the above embodiment.

  According to this modification, the inventory status of the stored items is searched at the timing when the door 12a is opened as the use start timing of the storage portion 11a and at the timing when the door 12a is closed as the use end timing. Since the usage history including the inventory status is stored in the storage unit 63, the inventory status of the stored items 111 at the start or end of each usage can be managed. Thereby, it is possible to specify and manage the time point or user when each stored item 111 is taken out or returned, and to manage the usage situation more appropriately.

  Moreover, since the key-side control unit 62B is incorporated in the electronic key 60B, it is not necessary to incorporate a search control device on the storage shelf 10 side. In addition, since the communication unit 112 is also configured to perform optical communication with the tag device 110 by receiving power supply from the electronic key 60B, it is not necessary to incorporate a power source on the storage shelf 10 side. For this reason, there is an advantage that the configuration added to the storage shelf 10 itself for performing the search can be simplified.

  It should be noted that the search operation may be performed to store the stock status of the stored items only at one of the use start timing and the use end timing. Further, the use start timing and the use end timing are not limited to the opening / closing timing of the door 12a, but as described in the above embodiment, timings according to various states in which the operation is controlled or changed with the start or end of use. It can be.
