  Next, FIG. 3 shows a block diagram of a control system of the key management machine 11 which is the article management device 10.

  The key management device 11 includes a first board 51 and a second board 52. The first board 51 and the second board 52 are communicably connected to each other. Main power is supplied from a main power supply 53 to the first substrate 51 and the second substrate 52. The main power supply 53 is provided in the main body 12, and supplies main power obtained by converting a commercial AC power supply obtained by connecting a power cord extending from the main power supply 53 to an outlet to a predetermined power supply voltage. The main power is supplied to the touch panel 44 and the display unit 45 of the display unit 15, the card reader 21, the lock mechanisms 27 of the key management unit 17, the printer 18, the key exchange unit 19, the first door locking mechanism 37, and the second It is also supplied to the door locking mechanism 40 and the like. Further, the main power may be supplied to each of the first substrate 51 and the second substrate 52, may be supplied from the first substrate 51 to the second substrate 52, or may be supplied from the second substrate 52 to the first substrate 51. May be supplied to the substrate 51.

  On the first substrate 51, a first control circuit 57 including a first control unit 55 and a first storage unit 56 is formed. The first control circuit 57 including the first control unit 55 and the first storage unit 56 operates by the main power.

  The first control unit 55 includes a touch panel 44 and a display unit 45 of the display unit 15, a card reader 21, each lock mechanism 27 of the key management unit 17 (including a holder locking unit, a holder detection unit and the lock display unit 30), a printer. 18 (including the winding unit 32), the key exchange unit 19 (including the key exchange regulation unit and the key exchange detection unit), the first door locking mechanism 37 (the first door electric drive unit and the first door).

  The first control unit 55 performs authentication for permitting removal of the key 26 from the key management device 11 based on the information of the card read by the card reader 21 and the password input on the touch panel 44 and the like. It has the function of one authentication unit 58. When a non-contact card reader or biometric authentication unit is connected to the outside of the key management device 11 or the key management device 11 is integrally provided, the first authentication unit 58 reads the non-contact card reader or biometric authentication unit. Authentication may be performed from information.

  The first storage unit 56 is configured by, for example, a RAM or a ROM such as a flash memory.

  The emergency dial lock 20 is a second authentication unit 59 that performs authentication for permitting removal of the key 26 from the key management device 11.

  In the present embodiment, the display unit 45 functions as a reporting unit 60 that reports various types of information. The notification unit 60 is not limited to the display unit 45, and may be a notification display unit provided separately from the display unit 45, or may notify by voice or the like.

  Further, on the second substrate 52, a second control circuit 63 including a second control unit 61 and a second storage unit 62 is formed.

  The second substrate 52 includes a battery 64 for supplying reserve power to a second control circuit 63 including a second control unit 61 and a second storage unit 62. As the battery 64, a small primary battery such as a button-type battery that can be incorporated in the second substrate 52 is used.

  The second control circuit 63 including the second control unit 61 and the second storage unit 62 operates with the main power when the main power is supplied, and operates when the main power is cut off. Operates on electric power. The second control circuit 63 includes a power switching circuit unit 65 that automatically switches to standby power when main power supply is cut off and automatically switches from standby power to main power when restarting main power supply.

  An emergency door opening / closing detection unit 66 that detects the opening / closing of the emergency door 16 is connected to the second board 52. The emergency door opening / closing detection unit 66 uses, for example, a microswitch, and operates by being supplied with power from the second board 52, that is, operates with either main power or standby power.

  The second control unit 61 includes a function of an abnormal state detection unit 67 that detects that the key management device 11 is in an abnormal state based on switching from the main power to the standby power by the power switching circuit unit 65, and a battery. It has a function of a battery remaining amount detecting unit 68 for detecting the remaining amount of the reserve power stored in the unit 64. Note that the abnormal state of the key management device 11 is also a state in which the key storage device 11 cannot be stored in the first storage unit 56.

  The second storage unit 62 is configured by, for example, a RAM or a ROM such as a flash memory.

  Then, the second control unit 61 operates continuously in the normal mode when the main power is supplied, and operates in the power saving mode intermittently when switched to the standby power. The second control unit 61 monitors the opening / closing of the emergency door 16 detected by the emergency door opening / closing detection unit 66 at least in the emergency state, and in the present embodiment, in the normal state and the emergency state, The operation history of opening and closing the emergency door 16 which is at least a part of the operation history of the key management device 11 and is detected by the emergency door opening / closing detection unit 66 is stored in the second storage unit 62. When the abnormal state is released, the second control unit 61 transmits the operation history stored in the second storage unit 62 to the first control unit 55 so as to transfer the operation history to the first storage unit 56. .

  Therefore, the second control unit 61 has the main control contents of monitoring the opening and closing of the emergency door 16, storing and reading the operation history in the second storage unit 62, and communicating with the first control unit 55. The control content is smaller than that of the first control unit 55, and it is possible to cope with the case where the processing capacity is lower than that of the first control unit 55. For this reason, the second control unit 61 has a lower processing capacity than the first control unit 55 and operates with low power consumption.

  The second storage unit 62 mainly stores the operation history of the opening and closing of the emergency door 16, and may have a smaller storage capacity than the first storage unit 56. Therefore, the second storage unit 62 has a smaller storage capacity than the first storage unit 56 and operates with low power consumption. The storage capacity of the second storage unit 62 is such that the operation history of the opening and closing of the emergency door 16 is smaller than the number of the operation history of the opening and closing of the emergency door 16 stored in the first storage unit 56. For example, it is a storage capacity capable of storing the operation history of opening and closing of ten emergency doors 16.

  As described above, since both the second control unit 61 and the second storage unit 62 of the second board 52 operate with power saving, the backup operation is performed when the key manager 11 is in the abnormal state in which the main power is shut off. Even if the battery 64 that supplies power is a small primary battery such as a button-type battery that can be incorporated into the second substrate 52, the battery 64 can be used for a long period of time. For example, the battery 64 can be used for 12 hours a day and 250 days a year, and can supply standby power for about 10 years.

  Note that, in the present embodiment, the first storage unit 56 and the second storage unit 62 are configured as a storage unit 70 included in the key management device 11.

  Next, the operation of the key management device 11 will be described. The description of the operation of the key management device 11 includes the description of the article management method and the history management method.

  First, the operation of removing the key 26 in the normal state of the key management machine 11 when the power of the key management machine 11 supplied with the main power is on will be described.

  The card of the operator who removes the key 26 is passed through the card reader 21, and then the operator inputs a password on an input screen displayed on the display unit 45. When the operator information is authenticated by the first authentication unit 58, a selection screen of the lock mechanism 27 from which the holder 24 can be extracted is displayed on the display unit 45.

  On the selection screen of the display unit 45, the selection buttons arranged in accordance with the actual arrangement of the lock mechanisms 27 and numbered for each lock mechanism 27 are displayed in a list, and the operator's removal authority registered in advance is displayed. The selection button corresponding to a certain key 26 is displayed in a different display form from the selection button corresponding to the key 26 for which the user does not have the removal right. Further, among the keys 26 having the removal authority, the selection button for the number of the lock mechanism 27 from which the key 26 is in the removal state and the selection button for the number of the lock mechanism 27 from which the key 26 can be removed are displayed in different colors. At this time, in the key management unit 17 of the main body 12, the display form of the lock display unit 30 of each lock mechanism 27 is synchronized.

  After the operator makes a selection on the selection screen of the display unit 45 and then performs a confirming operation, the selected lock mechanism 27 is unlocked. The operator removes the holder 24 from the lock mechanism 27, and removes the key 26 together with the holder 24 from the key management device 11 and uses it.

  When the holder detection unit of the lock mechanism 27 detects that the holder 24 has been removed from the lock mechanism 27, the first control unit 55 stores the operation history of the extraction information including the extraction date and time, the operator information and the key information in the first storage. Stored in the unit 56 (first management step of the article management method).

  Next, the operation of returning the key 26 will be described.

  The holder 24 of the key 26 to be returned is inserted into the insertion opening 29 of the corresponding lock mechanism 27. When the holder 24 is inserted to the predetermined locking position of the locking mechanism 27, the holder 24 is locked by the holder locking portion of the locking mechanism 27. Note that the return operation described here is a case of a normal operation that does not require an authentication operation, but may be a return authentication operation that requires an authentication operation to return the key 26, as in the case of the extraction operation.

  When the holder detection unit of the lock mechanism 27 detects that the holder 24 has been inserted and locked in the lock mechanism 27, the first control unit 55 stores the operation history of the return information including at least the return date and time in the first storage unit 56. (First management step of the article management method).

  Next, a key exchange operation for exchanging the key 26 connected to the holder 24 with another key 26 or adding another key 26 will be described.

  An authorized person having the key exchange authority selects the holder 24 to exchange keys on the touch panel 44 after authentication by inputting card information and a password in the same manner as described above. As a result, the lock mechanism 27 of the selected holder 24 is unlocked, the second door 14 is unlocked, and the key exchange restricting unit of the key exchange unit 19 is released from the restriction. Then, the holder 24 can be inserted into the state.

  The administrator removes the selected holder 24 from the lock mechanism 27, and inserts the extracted holder 24 into the insertion opening 33 of the key exchange unit 19. When the holder 24 is inserted into the insertion port 33, the release member in the insertion port 33 releases the lock between the holder main body and the ring locking body with respect to the holder 24, and the ring 25 can be removed.

  When the key exchange detection unit of the key exchange unit 19 detects that the holder 24 has been inserted into the insertion slot 33, the first control unit 55 causes the key exchange operation history including the exchange date and time, administrator information, key information, and the like to be displayed. It is stored in the first storage unit 56.

  Thereafter, the administrator can remove the ring 25 from the holder main body of the holder 24, thereby removing the ring 25. A ring 25 to which a key 26 to be exchanged is connected or a ring 25 to which another key 26 is added is mounted on a ring locking body, and this ring locking body is combined with a holder body and locked. When the ring lock is removed from the holder main body of the holder 24, the holder main body is removed from the insertion slot 33, and the operation of combining the holder main body of the holder 24 and the ring lock outside the key exchange unit 19 is performed. Is also good. Then, the holder 24 after the key exchange operation is inserted into the original lock mechanism 27.

  Next, the operation of the key management device 11 in an abnormal state will be described with reference to the flowchart of FIG. FIG. 4 shows the operation of the second control unit 61.

  The key management machine 11 is in an abnormal state in which the main power is shut off and the power is cut off when the power cord is pulled out from the outlet during a power outage or when the key management machine 11 is carried or stored in a safe. .

  When the main power to the first substrate 51 is cut off, the first control unit 55 stops operating, and when the first door 13 is closed, the first control unit 55 is kept in a locked state. Since the key 27 is held in the locked state of the holder 24, the key 26 cannot be removed by a normal key removal operation.

  On the other hand, in the second substrate 52, when the main power is cut off, the power switching circuit 65 automatically switches to the reserve power supplied from the battery 64, and the reserve control power causes the second control unit 61 and the second The operation of the storage unit 62 and the like is continued. Then, in the second control section 61, the abnormal state detecting section 67 detects an abnormal state of the key management machine 11 based on the switching from the main power to the standby power (step S1). When detecting the abnormal state (YES in step S1), the second control unit 61 switches from the normal mode to the power saving mode (step S2). The second control unit 61 in the power saving mode operates intermittently and suppresses consumption of reserve power.

  In the abnormal state of the key management device 11 in which the main power is shut off, the second control unit 61 detects the opening of the emergency door 16 by the emergency door opening / closing detection unit 66 (step S3) or the closing detection of the emergency door 16 (step S3). Monitor S4).

  Then, when the key 26 is taken out in the abnormal state of the key management machine 11 in which the main power is cut off, the display unit 15 is rotated upward to expose the emergency dial lock 20 which is the second authentication unit 59. Then, the emergency dial lock 20 is unlocked (see FIG. 2). The emergency dial lock 20 can be unlocked only by an operator such as an administrator who knows the unlocked number.

  When the emergency dial lock 20 is unlocked by the operator, the emergency door 16 on the rear side of the main body 12 is unlocked. When the emergency door 16 is opened by the operator, access to the back side of the key management unit 17 becomes possible, and the first door 13 is manually unlocked from the back side of the key management unit 17. Then, an arbitrary lock mechanism 27 is manually unlocked. Therefore, the first door 13 is opened by the operator, the holder 24 is pulled out of the lock mechanism 27, and the key 26 is taken out together with the holder 24.

  At this time, when the opening of the emergency door 16 is detected by the emergency door opening / closing detection unit 66 (YES in step S3), the second control unit 61 causes the operation history stored in the second storage unit 62 to be full. (Step S5). Here, if the predetermined number has not been reached (NO in step S5), the second control unit 61 stores the opening time of the emergency door 16 in the second storage unit 62 (step S6) (in the article management method). Second management step, first storage step of the history management method).

  When the emergency door 16 is closed after the key 26 is removed by the operator, the emergency door 16 is locked by the emergency dial lock 20.

  At this time, when the closing of the emergency door 16 is detected by the emergency door opening / closing detection unit 66 (YES in step S4), the second control unit 61 causes the operation history stored in the second storage unit 62 to be full. (Step S7). Here, if the predetermined number has not been reached (NO in step S7), the second control unit 61 stores the closing time of the emergency door 16 in the second storage unit 62 (step S8) (in the article management method). Second management step, first storage step of the history management method). As a result, one operation history in which the opening time and the closing time of the emergency door 16 are paired is stored in the second storage unit 62.

  When the key 26 is returned in the abnormal state, the emergency dial lock 20 is unlocked and the emergency door 16 is unlocked, so that the back side of the key management unit 17 can be accessed, and the key management can be performed. The first door 13 is manually unlocked from the rear side of the unit 17. After the first door 13 is opened and the returning holder 24 is attached to the corresponding lock mechanism 27, the emergency door 16 is closed. Also in this case, one operation history in which the opening time and the closing time of the emergency door 16 are paired is stored in the second storage unit 62.

  If the key 26 is repeatedly taken out and returned with the opening and closing of the emergency door 16, the number of operation histories stored in the second storage unit 62 may reach a predetermined number in step 4 at which the operation history is full. (YES in step S5 or YES in step S7).

  In this case, while the oldest operation history among the operation histories stored in the second storage unit 62 is stored, at least a part of the other operation histories is deleted (step S9 or step S10), and step S6 is performed. Alternatively, after step S8, a new operation history is newly stored (second storage step of the history management method).

  The erasing of the operation history includes erasing of the newest operation history stored in the second storage unit 62, erasing of the oldest operation history next to the oldest operation history stored in the second storage unit 62, and Of the insignificant operation histories of the operation histories stored in the storage unit 62 of the above is preferentially erased. It is important for the key management machine 11 to check the oldest operation history and the newest operation history at the time of occurrence of an abnormal state. The importance of the next oldest operation history is relatively low.

  FIG. 5 shows an example in which the latest operation history stored in the second storage unit 62 is deleted. For example, ten operation histories can be stored in the second storage unit 62. If ten operation histories have already been stored in the second storage unit 62, in step S9 or step S10, the tenth most recent operation history that has already been stored is erased (a plurality of erased states are deleted). (Shown by a downward arrow), and after step S6 or step S8, a new tenth (lowest) operation history is newly stored. FIG. 5 shows an example in which the emergency door 16 is opened and closed in a short time to record 10 or more operation histories.

  Even if the operation history is deleted, the history of the number of the stored operation histories is separately stored in the second storage unit 62.

  In the abnormal state of the key management machine 11, the monitoring of the emergency door 16 opening detection (step S3) in step S3 and the monitoring of the emergency door 16 closing detection in step S4 are performed by the main power supply. This is because if the main power is shut off while the emergency door 16 is open when the emergency door 16 is supplied, the operation history detected first may be that the emergency door 16 is closed.

  Further, when the power failure is eliminated or the power cord is connected to the outlet and the main power supply is resumed, the operations of the first control unit 55 and the first storage unit 56 on the first board 51 are started. The key 26 can be extracted by a normal key extraction operation. At this time, the presence or absence of the holder 24 may be checked, and the check result may be recorded.

  On the other hand, in the second board 52, the power switching circuit 65 automatically switches from the reserve power of the battery 64 to the main power, and the main power causes the operations of the second control unit 61 and the second storage unit 62 to operate. To be continued. Then, the second control unit 61 cancels the detection of the abnormal state of the key management machine 11 by the abnormal state detecting unit 67 based on the switching from the standby power to the main power. When the detection of the abnormal state is released (NO in step S1), the second control unit 61 switches from the power saving mode to the normal mode (step S11). The second control unit 61 in the normal mode operates continuously.

  Then, when the first control unit 55 and the second control unit 61 can communicate with each other, the second control unit 61 checks whether the operation history is in the second storage unit 62 (step S12). Note that the first control unit 55 that has started operation by the main power requests the second control unit 61 to transmit the operation history stored in the second storage unit 62, thereby confirming the operation history. May be performed.

  For example, if the emergency door 16 has not been opened or closed in the abnormal state, it is determined that the operation history is not in the second storage unit 62 (NO in step S12). In this case, the second control unit 61 may notify the first control unit 55 that there is no operation history.

  If the operation history is stored in the second storage unit 62 (YES in step S12), the operation history stored in the second storage unit 62 is transferred to the first storage unit 56 by the second control unit 61. (Step S13) (Transition step of the history management method). After the operation history stored in the second storage unit 62 is transferred to the first storage unit 56, the transferred operation history stored in the second storage unit 62 may be deleted. .

  Even when the main power is supplied, if the emergency door 16 is unlocked by the emergency dial lock 20 and the emergency door 16 is opened and closed as in steps S3 to S8, the operation history is stored in the second storage. The operation history stored in the unit 62 and stored in the second storage unit 62 is transferred to the first storage unit 56.

  The operation history transferred to the first storage unit 56 can be confirmed by displaying the operation history on the display unit 45 or outputting a journal in which the operation history is printed on paper by the printer 18.

  Further, the second control unit 61 monitors the remaining amount of the reserve power stored in the battery 64 by the function of the battery remaining amount detecting unit 68. Then, when the remaining amount of the reserve power stored in the battery 64 decreases to a predetermined amount, the notification unit 60 notifies the notification. For example, when the notification unit 60 is the display unit 45, notification information is transmitted from the second control unit 61 to the first control unit 55, and the first control unit 61 notifies the display unit 45. In the case where the notification unit 60 is configured by, for example, an LED display lamp different from the display unit 45, the second control unit 61 may notify the LED display lamp by lighting or blinking. By notifying that the remaining amount of the battery 64 is low, the staff can replace the battery 64 or charge the battery 64 when a secondary battery is used as the battery 64. Further, the charging of the battery 64 may be performed by the main power. The detection of the remaining amount of the reserve power stored in the battery 64 is not limited to being performed by the second control unit 61, but may be performed by the first control unit 55.

  As described above, according to the key management device 11 that is the article management apparatus 10 and the article management method, the first control unit 55 and the second control that operates with lower power consumption than the first control unit 55 Since the second control unit 61 stores at least a part of the operation history of the key management device 11 in the storage unit 70 by using the unit 61, it is possible to cope with power saving, and the key management device 11 is required. Operation history can be reliably left, and the management of the key 26 can be made strict.

  Further, at least when the key management device 11 is in an abnormal state, at least a part of the operation history of the article management device is stored in the storage unit 70. Management can be strict.

  Further, as the storage unit 70, a first storage unit 56 and a second storage unit 62 having a smaller storage capacity than the first storage unit 56 and operating with power saving are used, In the state, at least a part of the operation history of the key management device 11 is stored in the second storage unit 62 by the second control unit 61, so that it is possible to cope with further power saving.

  The second control unit 61 and the second storage unit 62 operate with a standby power different from the main power when the key management device 11 is in an abnormal state. Consumption can be suppressed.

  Even when the reserve power is supplied from the battery 64, the consumption of the reserve power of the battery 64 can be suppressed, so that a small battery 64 can be used.

  Since the notification unit 60 notifies that the reserve power stored in the battery 64 is small, it is possible to prevent the operation history from being unable to be stored in the abnormal state due to the lack of reserve power of the battery 64.

  Further, although the abnormal state is a state that cannot be stored in the first storage unit 56, a necessary operation history can be left in the second storage unit 62.

  Furthermore, since an abnormal state detecting section 67 for detecting an abnormal state is provided, the operation history can be stored in the storage section 70 (second storage section 62) by the second control section 61 in the abnormal state.

  The abnormal state detection unit 67 determines at least one of the operation abnormality state of the first storage unit 56, the operation abnormality state of the first control unit 55, and the open state of the emergency door 16 in addition to the main power cutoff state. It may be detected. In any abnormal state, the operation history can be stored in the storage unit 70 (second storage unit 62) by the second control unit 61. Then, the cutoff state of the main power can be detected by switching the power supplied to the second substrate 52 from the main power to the standby power. The abnormal operation state of the first storage unit 56 can be detected by the first control unit 55 determining an abnormal operation such as an abnormal storage of the first storage unit 56. An abnormal operation state of the first control unit 55 can be detected based on a communication abnormality between the first control unit 55 and the second control unit 61 and the like. The open state of the emergency door 16 can be detected based on the emergency door open / close detection unit 66.

  Further, since a second authentication unit 59 (emergency dial lock 20) for permitting removal of the key 26 stored in the plurality of storage units 31 (lock mechanism 27) is provided, the second authentication unit can be used even in an abnormal state. The key 26 can be taken out using the emergency dial lock 20 (59), and at least a part of the operation history related to taking out the key 26 using the second authentication unit 59 (emergency dial lock 20) is stored in the second memory. The necessary operation history can be stored in the unit 62 and left.

  The second authentication unit 59 (emergency dial lock 20) is operable even in an abnormal state, so that the key 26 can be taken out.

  Furthermore, since the first storage unit 56 and the second storage unit 62 are provided at different locations, that is, the first storage unit 56 and the second storage unit 62 are separate components, As the second storage section 62, a storage section having a smaller storage capacity than that of the first storage section 56 and operating with low power consumption can be used.

  Further, according to the history management method for managing the operation history of the key management device 11 as the article management device 10, the first storage step of storing the operation history of the key management device 11 in the storage unit 70, A second storage step of erasing at least a part of the other operation histories while storing the oldest operation history of the stored operation histories, and newly storing a new operation history. Can be reduced, power saving can be achieved, the necessary operation history of the key management device 11 can be reliably left, and the management of the key 26 can be strict.

  Further, as the storage unit 70, a first storage unit 56 and a second storage unit 62 that has a smaller storage capacity than the first storage unit 56 and operates with low power consumption are used. The operation history of the key management device 11 in the normal state is stored in the first storage unit 56, the operation history of the key management device 11 in the abnormal state is stored in the second storage unit 62, and the second storage step is performed. In, while the oldest operation history of the operation history stored in the second storage unit 62 is stored, at least a part of the other operation history is deleted, and a new operation history is newly stored. It is possible to cope with further power saving.

  In the second storage step, the oldest operation history stored in the second storage unit 62 is deleted while the oldest operation history of the operation history stored in the second storage unit 62 is stored. Is newly stored, or the oldest operation history next to the oldest operation history stored in the second storage unit 62 is deleted, and a new operation history is newly stored, or The operation history that is not important among the operation histories stored in the second storage unit 62 is preferentially erased, and a new operation history is newly stored. It is important for the key management machine 11 to check the oldest operation history and the newest operation history at the time of occurrence of an abnormal state. Since the operation history of the second oldest is relatively low in importance, the necessary operation history of the key management device 11 can be reliably left, and the management of the key 26 can be strict.

  Further, in the history management method, when the abnormal state of the key management device 11 is released, the operation history stored in the second storage unit 62 is transferred to the first storage unit 56. A new operation history can be newly stored in the second storage unit 62, which can be managed by the first storage unit 56 and has a small storage capacity.

  Further, in the history management method, the operation history is an operation history relating to the extraction of the key 26, and a necessary operation history of the key management device 11 can be reliably left, and the management of the key 26 can be strict.

  In the present embodiment, the first storage unit 56 and the second storage unit 62 are provided as the storage unit 70 of the key management device 11, but the number of the storage unit 70 may be one. That is, the shape and structure of the first storage unit 56 and the second storage unit 62 are not limited as long as they perform the above-described operations. For example, the first storage unit 56 and the second storage unit 62 do not necessarily have to be separate bodies, and may be realized by dividing the use area of one storage unit 70.

  Further, in the present embodiment, the key 26 stored in the plurality of storage sections 31 (lock mechanism 27) can be taken out using the second authentication section 59 (emergency dial lock 20) in an abnormal state. However, the keys 26 stored in an arbitrary storage unit 31 (lock mechanism 27) may be taken out one by one using the first authentication unit 58. Also in this case, the second control unit 61 stores at least a part of the operation history related to the removal of the key 26 using the first authentication unit 58 in the second storage unit 62 in the abnormal state. . Furthermore, by supplying reserve power to the first authentication unit 58 in the abnormal state, the first authentication unit 58 can be operated even in the abnormal state.

  Further, the mechanism may be such that the first door 13 is opened by authentication of the emergency dial lock 20 and all the locks of the holders 24 are unlocked by a predetermined mechanical key operation. In that case, the opening history of the first door 13 is stored as a log.

  Further, in the present embodiment, the operation history information when the main power is turned off and when the power is turned on may be compared. By comparing these pieces of operation information, if there is any new information in the operation information, it is possible to quickly and easily determine that some operation has been performed when the main power is turned off.

  If any information has disappeared from the operation information, it is possible to quickly and easily determine that an unauthorized operation may have been performed on the storage unit 70 when the main power is turned off.

  Further, the comparison target of the operation information is not limited to the entire operation information, and for example, it is also possible to compare only the operation history of each holder 24, the operation history of a specific holder 24, and the operation history of a predetermined time. The comparison object itself is not particularly limited.

  If there is an abnormality (that is, a difference) in the comparison result, the operator may be notified. When the comparison is performed for each holder 24, a notification may be provided so that the operator can know which holder 24 has the abnormality.

  Furthermore, if there is an abnormality (that is, a difference) in the comparison result, the operation history information of the difference portion may be output on a screen, transmitted to the outside, or printed.
