Even when the key / holding unit identification number is input to the operation unit 21, the control unit 55 recognizes the selected and designated key holding unit 31, drives the key lock mechanism 46 to release the lock, and displays the display. The lamp 50 is switched from blinking to lighting.

  Then, the control unit 55 detects the take-out when the IC tag reader 52 of the key holding unit 31 cannot communicate with the IC tag 43 of the key holder 11. The control unit 55 returns the display lamp 50 detected to be taken out to a blinking state, and also identifies the person-in-charge identification number of the ID card 23 read when the key holder 11 is taken out, and the key holding unit 31 in which the operation button 51 is pressed. Key / holding unit identification number, key holder 11 from the key holding unit 31 where the operation button 51 is pressed, that is, the time when the key 10 is taken out, and the return time (the data is blank because it has not been returned at this point) The storage unit 56 stores the carry-out status data as shown in FIG.

  In the example of the carry-out status data shown in FIG. 8A, the key holder 11 with the key 10 from the key holding unit 31 with the key / holding unit identification number “001” is assigned to the person identification number with “777”. The person in charge took out at the takeout time of “10:10” and returned at the return time of “10:20”. That is, the control unit 55 associates the take-out time and return time, which are detection results of the IC tag reader 52, with the key / holding unit identification number stored in the IC tag 43 that is the detection target of the IC tag reader 52, and stores the storage unit 56. Remember me. Of course, even if the operation button 51 other than the blinking of the display lamp 50 is operated, the control unit 55 does not release the locked state of the key holding unit 31 provided with the operation button 51. .

  Then, each time the key holder 11 with the key 10 is taken out, the control unit 55 causes the storage unit 56 to store the above-described take-out status data in time-series in order of take-out time, and store the log data for storage. create.

  The person in charge closes the cover 16 after taking out the key holder 11 with the key 10 (the same is true after returning the key holder 11 described later). Then, the engagement protrusion 18 of the cover 16 enters the engagement insertion hole 32 of the apparatus main body 14, and the detection protrusion 19 of the cover 16 enters the detection insertion hole 33 of the apparatus main body 14. Thus, when the close detection sensor 37 detects the detection protrusion 19, the control unit 55 locks the cover 16 in the closed state by the cover lock mechanism 35. Note that when a lock operation is input to the operation unit 21 in a state where the detection protrusion 19 is detected by the close detection sensor 37, the cover lock mechanism 35 may lock the cover 16 in the closed state.

  Next, the return time will be described. The person in charge opens the unlocked cover 16, and from the key holding unit 31 where the display lamp 50 is flashing, the key / key displayed on the key identification notation unit 44 of the key holder 11 with the key 10. The key holder 11 is inserted into the key holder mounting hole 45 of the key holding part 31 having the holding part identification notation part 53 in which the same key / holding part identification number as the holding part identification number is written (one or more key holders may be provided). ). Then, the control unit 55 reads the key / holding unit identification number from the IC tag 43 of the key holder 11 by the IC tag reader 52, and this key / holding unit identification number becomes the key / holding unit identification number of the key holding unit 31. Check if they match. Only when these key / holding unit identification numbers match, the return of the key holder 11 with the key 10 is detected, and the key holder 11 is locked by the key lock mechanism 46. At the same time, the control unit 55 sets the time when the key holder 11 with the key 10 is detected as the return time of the latest carry-out status data having the key / holding unit identification number stored in the storage unit 56. Write.

  On the other hand, the control unit 55 does not lock the key holder 11 by the key lock mechanism 46 when the key holding unit 31 and the key / holding unit identification number of the key 10 do not match, and the operation button 51 of the key holding unit 31 is not locked. The display lamp 50 is turned on to generate a notification sound by the buzzer 26 and an alarm display (including a display for guiding correct operation) on the display unit 22.

"Exchange mode"
The exchange mode will be described. After the ID card 23 is scanned by the card reader 24, the exchange mode is selected, and a password set for permitting management of the key 10 is input to the operation unit 21. Then, the control unit 55 collates the person-in-charge identification number of the ID card 23 read by the card reader 24 and the password entered in the operation unit 21 with the data stored in the storage unit 56, thereby It is determined whether or not the password is proper for executing the exchange mode. When it is appropriate, that is, when the identification number of the person in charge who has been given the specific authority to execute the exchange mode and the password are input, the control unit 55 drives the cover lock mechanism 35 to unlock the cover 16. In addition, a screen prompting the selection operation of the key holding unit 31 to be exchanged is displayed on the display unit 22, and the key having the exchangeable key / holding unit identification number registered for the input person identification number The display lamp 50 of the operation button 51 provided for the holding unit 31 is blinked. The person in charge opens the cover 16 and presses the operation button 51 of the desired key holder 31 to be exchanged (one or more) from among the operation buttons 51 whose display lamps 50 are blinking.

  Then, the control unit 55 recognizes that the key / holding unit identification number of the key holding unit 31 where the operation button 51 is pressed is selected and specified, and the key holding unit 31 provided with the operation button 51 is recognized. The key lock mechanism 46 is driven to release the lock so that the key holder 11 can be removed, and the display lamp 50 of the operation button 51 is switched from blinking to lighting to guide this state. Thus, the person in charge removes the key holder 11 from the key holding unit 31 by releasing the lock state of the key holding unit 31. Even when the key / holding unit identification number is input to the operation unit 21, the control unit 55 recognizes the selected and designated key holding unit 31, drives the key lock mechanism 46 to release the lock, and displays the indicator lamp. 50 is switched from blinking to lighting. The key holder 11 held by the operation button 51 or the key holding unit 31 designated by the operation unit 21 is a target for releasing the connection state of the key 10 by the connection mechanism 61 as will be described later. 50 guides the designated key holder 11 by switching from blinking to lighting.

  When the key holder 11 is removed from the key holding unit 31, the control unit 55 detects the removal when the IC tag reader 52 of the key holding unit 31 becomes unable to communicate with the IC tag 43 of the key holder 11. Then, the control unit 55 determines that the person-in-charge identification number of the ID card 23 read when the key holder 11 is removed, the key / holding unit identification number of the key holding unit 31 where the operation button 51 is pressed, and the operation button 51 The removal time of the key holder 11 from the pressed key holder 31, the replacement time of the key 10 of this key holder 11 (the data is blank since it is not replaced at this point), and the operation button 51 The replacement state data including the reattachment time to the key holding unit 31 where is pressed (the data is blank because it is before reattachment at this time) is stored in the storage unit 56. Also, in this replacement status data, the release tool removal time when the release tool 81 was taken out from the storage unit 34 (the data is left blank at this point because it was before removal), and the release tool 81 is stored in the storage unit 34. And the release tool storage time stored in (the data is blank since it has not been taken out at this time).

  In the example of the distribution status data shown in FIG. 8B, the key holder 11 is moved from the key holding unit 31 with the key / holding unit identification number “021”, and the person in charge with the person identification number “711” It is removed at the removal time of “13:15”, the key 10 is changed at the replacement time of “13:17”, the reattachment is erroneous at the time of “13:18”, and the reattachment time of “13:19”. The release tool 81 is attached to the storage unit 34 having the identification number “000” and the person in charge with the person identification number “711” takes the release tool removal time “13:16”. This indicates that the device is taken out and stored at the release tool storage time of “13:20”. That is, the control unit 55 associates the removal time and reattachment time as detection results of the IC tag reader 52 and the replacement time as detection result of the IC tag reader 87 with the key / holding unit identification number in the storage unit 56. Remember me.

  Then, each time the key 10 is changed, the control unit 55 causes the storage unit 56 to store the above-described replacement status data in a time series, and creates storage log data.

  Next, the control unit 55 causes the display unit 22 to display a screen that prompts input of usage information of the key 10 after replacement of the key holding unit 31 from which the key holder 11 has been removed, and accepts the input of usage information. Become. The person in charge re-enters the usage information through kana input, alphabet input, or the like using the operation key 21a of the operation unit 21. For example, as shown in FIG. 7, as usage information for the key / holding unit identification number “001”, “kinko-villa” is input as changed from before, or the key / holding unit identification number “ As the usage information for "002", change "ATM1 GOBILLA" as before, or as the usage information for "003" as the key / holding unit identification number, change it as before. “A key” is entered, or “ATM1 Goki Kaishu key” is entered as usage information for the key / holding unit identification number “004”. When the input is made in this way, the control unit 55 causes the storage unit 56 to store the usage information in association with the key / holding unit identification number selected and designated at the time of the input. That is, when the control unit 55 receives the selection designation of the key holding unit 31 to the operation button 51 or the operation unit 21, the control unit 55 relates to the key / holding unit identification number of the selected and designated key holding unit 31 and the selection designation. Then, it is stored in the storage unit 56 in association with the application information input by the operation unit 21.

  When an operation input indicating that the use information has been input is input to the operation unit 21, the control unit 55 causes the display unit 22 to display a screen that prompts the user to change the key 10 and is provided to the storage unit 34. The display lamp 93 of the operation button 94 is flashed. Looking at this, the person in charge presses the operation button 94. Then, the control unit 55 switches the display lamp 93 from blinking to lighting, and drives the door lock mechanism 91 to unlock the open / close door 90 of the storage unit 34. Thereafter, the person in charge opens the opening / closing door 90 of the storage unit 34 and takes out the release tool 81. As described above, the control unit 55 grants access to the release tool 81 based on the authentication result of the person-in-charge identification number of the ID card 23 and the input password. When the open / close door 90 is opened, the closing detection sensor 92 detects this, and at that time, the control unit 55 uses the time as the release tool removal time of the release tool 81 of the replacement status data described above. The data is stored in the storage unit 56.

  Then, the person in charge takes the released release tool 81 in such a posture that the two extending portions 83 shown in FIG. 6 are positioned on the contact surface 75 side shown in FIG. The portion 84 is inserted into the two groove portions 78 of the lock body 63 in the locked state, and the substrate portion 82 is brought into contact with the side surface of the key holder 11. In this state, as shown in FIG. 5A, the release tool 81 is attached together with the lock body 63 until the two extending portions 83 abut against the end of the slit 70 opposite to the abutting surface 75. It is made to slide against the urging force of the urging spring 64 to be in the unlocked state. Then, while maintaining this unlocked state, as shown in FIG. 5B, the key code ring 62 is rotated to expose the notch 72 to the outside, and the old key 10 that has been attached is removed. The new key 10 is attached and replaced.

  When the substrate portion 82 of the release tool 81 is brought into contact with the side surface of the key holder 11, the IC tag reader 87 shown in FIG. 6 provided on the substrate portion 82 is moved from the IC tag 43 of the key holder 11 shown in FIG. The holding unit identification number is read, and when the key / holding unit identification number matches the key / holding unit identification number of the key holding unit 31 selected and designated, the control unit 55 sets the time to this key. -It memorize | stores in the memory | storage part 56 as the replacement time of the replacement status data in a holding | maintenance part identification number. If the key / holding unit identification numbers do not match, an alarm such as a notification sound by the buzzer 26 and an alarm display on the display unit 22 (including a display for guiding correct operation) is generated, and the key / holding unit identification numbers match. Wait until

  When the key 10 is changed via the notch 72, the person in charge releases the pressing to the release tool 81 and rotates the key code ring 62 to place the notch 72 in the key holder 11. The position 72 is aligned with the lock body 63. Then, the lock body 63 moves together with the release tool 81 by the urging force of the urging spring 64, abuts against the abutment surface 75 and stops. In this state, the person in charge removes the release tool 81 from the key holder 11.

  Then, the person in charge inserts the key holder 11 after the replacement of the key 10 into the key holder mounting hole 45 of the key holding part 31 having the holding part identification notation part 53 having the same notation as the key identification notation part 44 of the key holder 11. Will do. Then, in the key holding unit 31, the IC tag reader 52 communicates with the IC tag 43 of the key holder 11 to read the key / holding unit identification number, and the key / holding unit identification number and the key / holding unit identification number are read. If the key / holding unit identification number of the key holding unit 31 having the IC tag reader 52 whose number is detected matches, the key holder 11 is locked by the key lock mechanism 46 and provided to the key holding unit 31. The display lamp 50 of the operation button 51 is flashed. If the key / holding part identification number does not match, the key / holding part identification number is generated without generating a lock by generating a notification sound by the buzzer 26 and an alarm display (including a display for guiding correct operation). Wait until matches. When the key / holding unit identification numbers match, the control unit 55 stores the time in the storage unit 56 as the reattachment time of the above-described replacement status data.

  The step of selecting and specifying the operation button 51 of the key holding unit 31, the step of inputting usage information, the step of storing the association of the key / holding unit identification number and usage information of the selected and specified key holding unit 31, the key Step of detecting key / holding unit identification number by IC tag reader 87 from IC tag 43 of holder 11 and confirmation of matching of key / holding unit identification number, key / holding unit by IC tag reader 52 from IC tag 43 of key holder 11 The steps of detecting the identification number and confirming the coincidence of the key / holding unit identification numbers are performed for the number of the keys 10. In the meantime, by comparing with the reference step data stored in the storage unit 56, for example, before the opening detection step of the opening / closing door 90 by the closing detection sensor 92 or from the IC tag 43 of the key holder 11. Before the step of detecting the key / holding unit identification number by the IC tag reader 87, the step of detecting the key / holding unit identification number by the IC tag reader 52 from the IC tag 43 of the key holder 11 is performed. If there is an error, the control unit 55 generates a notification sound by the buzzer 26, an alarm display on the display unit 22 (including a display for guiding correct operation), and the like.

  When the replacement of the key 10 is completed, the person in charge stores the release tool 81 together with the communication line 88 in the storage unit 34 and closes the open / close door 90. Then, the close detection sensor 92 detects this, and the control unit 55 locks the open / close door 90 in the closed state by the door lock mechanism 91 and displays on the display unit 22 a prompt for an operation to close the cover 16. Do. Then, the person in charge closes the cover 16. Then, the engagement protrusion 18 of the cover 16 enters the engagement insertion hole 32 of the apparatus main body 14, and the detection protrusion 19 of the cover 16 enters the detection insertion hole 33 of the apparatus main body 14. Thus, when the close detection sensor 37 detects this detection protrusion 19, the cover lock mechanism 35 automatically locks the cover 16 in the closed state, and the exchange mode is terminated. In this case, the cover lock mechanism 35 may lock the cover 16 in the closed state when a lock operation is input to the operation unit 21 with the detection protrusion 19 detected by the close detection sensor 37.

  When the closing detection sensor 92 detects the closed state of the open / close door 90, the control unit 55 stores the time in the storage unit 56 as the release tool storage time of the replacement status data described above. Also in this case, by comparing with the reference step data stored in the storage unit 56, for example, before the step of opening / closing the door 90 by the closing detection sensor 92, or from the IC tag 43 of the key holder 11 Close detection before the step of detecting the key / holding part identification number by the tag reader 87 and before the step of redetecting the key / holding part identification number by the IC tag reader 52 from the IC tag 43 of the key holder 11 is performed. If there is an error in the order of the steps, such as when the sensor 37 detects the closed state of the detection projection 19, that is, the cover 16, the control unit 55 displays a notification sound by the buzzer 26 and an alarm display on the display unit 22. Display, etc.).

  As described above, the control unit 55 performs the step of removing the key holder 11 held by the key holding unit 31 guided by the display lamp 50 of the operation button 51 from the apparatus main body 12, and the opening / closing door 90 is opened to the release tool 81. The step of accessing, the step of reattaching the removed key holder 11 to the apparatus main body 12, and the step of reading the key / holding unit identification number from the IC tag 43 by the IC tag reader 87 are confirmed. Then, the control unit 55 confirms the match between the predetermined order registered in the storage unit 56 in advance of the step and the order that has progressed during the actual operation of the step, and notifies the match confirmation result.

  In the exchange mode, when the lock of the key holding unit 31 having the exchangeable key / holding unit identification number can be released by the operation button 51, the operation button 94 locks the door 90 of the storage unit 34. After the key 10 is replaced so that it can be operated, the key holder 11 is inserted into the key holder mounting hole 45 of the target key holder 31 and the IC tag reader 52 communicates with the IC tag 43 of the key holder 11 to After confirming the matching of the holding unit identification numbers, the usage information corresponding to the key / holding unit identification number may be input to the operation unit 21.

"New registration mode"
In the new registration mode, the controller 55 drives the cover lock mechanism 35 to lock the cover 16 only when the person-in-charge identification number and the personal identification number that have been given specific authority to execute the new registration mode are input. Except for canceling, it is almost the same as the exchange mode.

"Log Output Mode"
The log output mode will be described. After the ID card 23 is scanned by the card reader 24, the log output mode is selected, and a password set for permitting management of the key 10 is input to the operation unit 21. Then, the control unit 55 collates the person-in-charge identification number of the ID card 23 read by the card reader 24 and the password entered in the operation unit 21 with the data stored in the storage unit 56, thereby It is determined whether or not the password is proper for executing the log output mode. If it is appropriate, the control unit 55 reads the above-mentioned storage log data stored in the storage unit 56, and each of the export status data and the distribution status data constituting the storage log data For each of the holding unit identification numbers (that is, the key / holding unit identification number of the key holding unit 31 that has received the selection designation), the related usage information is read from the storage unit 56, and each of the carry-out status data and the distribution status data The corresponding usage information is included in each.

  In this manner, output log data (log information including usage information) as shown in FIG. 9 is created in which take-out status data and distribution status data each including usage information are arranged in time series. In the example of the output log data shown in FIG. 9, the key 10 of “Kinko Villa” is received from the key holding unit 31 with the key / holding unit identification number “001” on the date of “2012/3/3”. The person in charge with the identification number of “777” took out at the take-out time of “10:10” and returned at the return time of “10:20”, and the key / holding unit identification number of “002”. The person in charge with the identification number of “789” takes out the key 10 having the usage information of “ATM1 GOBILLA” from the key holding unit 31 at the time of taking out of “10:15”. The key 10 having the usage information of “ATM1 Gouki Shunoko A Kagi” from the key holding unit 31 of the key / holding unit identification number “003” is returned at the return time, and the person in charge of the person identification number “789” However, at the time of taking out “10:16” The key 10 having the usage information of “ATM1 Goki Kaishu Kagi” from the key holding unit 31 with the key / holding unit identification number of “004” is returned to “789”. This indicates that the person in charge with the person-in-charge identification number took out at the take-out time of “10:17” and returned at the return time of “10:27”.

  In addition, in the example of the output log data shown in FIG. 9, the key holder 11 with the key 10 is identified from the key holding unit 31 with the key / holding unit identification number “021”. The person in charge of the number removes at the removal time of “13:15”, replaces the key 10 at the replacement time of “13:17”, and mistakenly reattaches at the time of “13:18”. "" Indicates that it was properly installed at the time of re-installation, and that the application was changed to "Kinko Villa." Furthermore, the person in charge of the person-in-charge identification number “711” takes out the release tool 81 from the storage unit 34 with the identification number “000” at the time of taking out the release tool “13:16”. 20 ”indicates that the release tool is stored at the storage time. That is, the control part 55 and the memory | storage part 56 leave the confirmation condition of the order of the step which advanced in the case of operation as a log | history. At that time, a history of the mistaken procedure is also recorded. For example, when a plurality of key holders 11 are designated and the key 10 is changed, it can be seen from which history the key 10 has been changed in order from the history.

  Here, the output log data includes, for example, take-out status data and replacement status data stored after the take-out status data and replacement status data included in the output log data that was output last time. Data, which is composed of take-out status data and replacement status data stored on the day of output, and which is composed of take-out status data and delivery status data stored on the date or period specified and input to the operation unit 21 Things.

  Then, the control unit 55 causes the printer unit 25 to output the output log data created in this way onto a sheet. The log data for output may not be output to paper by the printer unit 25 but may be output and stored in a data management device comprising a separate personal computer. Output to paper and storage in the data management device You may do both.

  The control unit 55 does not cause the printer unit 25 to output the output log data when the operation unit 21 accepts the output operation as described above, but starts from a reference time point when the main power is turned on. It may be determined whether the predetermined time has elapsed, and when it is determined that the predetermined time has elapsed, the output log data may be output to a sheet or a separate data management device. Alternatively, it is determined whether or not a predetermined time (for example, one week) has elapsed since the reference time when the log data for output was output last time, and is output when it is determined that the predetermined time has elapsed. Log data may be output to paper or a separate data management device. Alternatively, the control unit 55 uses the clock function to determine whether or not a predetermined time set in advance is reached, and when it is determined that the predetermined time is reached, the log data for output is printed on paper or separately. The data may be output to the data management apparatus. Furthermore, you may make it combine these suitably.

  According to the key management device 1 of the first embodiment described above, the control unit 55 authenticates based on the input to the operation unit 21 and the card reader 24 when the key 10 is replaced or newly attached to the key holder 11. If the access to the release tool 81 is permitted based on the authentication result, the release tool 81 can release the connection state of the key holder 11 to the key 10 by the connection mechanism 61. In this state, the key of the key holder 11 can be released. 10 will be replaced. In this way, only a person who has been given a specific authority by preparing a dedicated release tool 81 for releasing the connection of the key 10 by the connection mechanism 61 and requiring authentication for access to the release tool 81. Therefore, unauthorized removal of the key 10 from the key holder 11 can be prevented. Further, if the control unit 55 grants access to the release tool 81 based on the authentication result, the connection state of the connection mechanism 61 can be released by the release tool 81, so that it is not necessary to destroy the member. Therefore, it is possible to facilitate the replacement work of the key 10 and reduce waste.

  Further, when the key holder 11 to be released from the connection state of the key 10 by the connection mechanism 61 is designated by the operation button 51, the display lamp 50 of the operation button 51 changes from blinking to lighting, and the designated key is displayed. The holder 11 will be guided. Thereafter, the control unit 55 includes a step of removing the guided key holder 11 from the apparatus main body 12, a step of accessing the release tool 81, and a step of remounting the removed key holder 11 to the apparatus main body 12. Check. Therefore, stricter management is possible for the operation of releasing the connected state of the key holder 11.

  Further, the control unit 55 confirms the step of reading the key / holding unit identification number from the IC tag 43 of the key holder 11 by the IC tag reader 87 provided in the release tool 81, so that any of the key holders 11 can be connected. Since the key / holding unit identification number indicating whether or not to perform the release is also confirmed when the release is performed by the release tool 81, stricter management becomes possible.

  In addition, since the control unit 55 confirms the match between a predetermined order registered in advance in each step and the order progressed in the operation of each step, the control unit 55 notifies the match confirmation result. An error in the procedure can be notified.

  Moreover, since the control part 55 leaves the confirmation state of the order which progressed in the case of step operation in the memory | storage part 56 as a log | history, there exists an effect which further raises the security which concerns on cancellation | release of the connection mechanism 61. FIG. In other words, when and who made which key holder 11 a target and how it was released during exchange or new registration, it remains in the log as detailed history information and can be referred to.

  Further, when the notch 72 is positioned inside the key holder 11 and engages with the lock body 63, the key code ring 62 holds the key 10 with the key holder 11 so that the lock body 63 cannot be removed. When engaged with the release tool 81 and slid, the cutout portion 72 is released from the lock body 63 and can be positioned outside the key holder 11 so that the key 10 can be replaced. Thereby, the structure of the connection mechanism 61 is simplified, and connection and release are facilitated.

  Further, since the lock body 63 is provided with a plurality of groove portions 78 with which the release tool 81 is engaged, the structure of the dedicated release tool 81 can be complicated, and unlocking other than the release tool 81 can be well regulated. Note that the more the grooves 78 and the engaging claws 85 are increased, the higher the effect of being able to better regulate unlocking other than the release tool 81.

  In the first embodiment described above, as shown in FIG. 10, the lock body 63 is engaged with the inside of the key holder 11 in a state of being engaged with the notch 72, and the release tool 81 is engaged with the groove 78. At this time, a locking claw 98 for releasing the locking inside the key holder 11 may be provided. Accordingly, the state in which the lock body 63 is engaged with the notch 72 can be firmly maintained, and the engagement between the lock body 63 and the inside of the key holder 11 (that is, the accommodation space 68) can also be firmly maintained.

  Next, a second embodiment of the key management apparatus according to the present invention will be described below mainly with reference to FIG. 11 with a focus on differences from the first embodiment.

  In the second embodiment, a connecting mechanism (connecting means) 61 is partially different from the first embodiment. The coupling mechanism 61 of the second embodiment has a rectangular key code ring (sliding body) 62 ′ that is slidably provided on the key holder 11. A straight insertion hole 69 ′ that opens one end side in the extending direction of 68 to both the upper and lower sides is formed. The key code ring 62 ′ is inserted into the linear insertion hole 69 ′ so as to be slidable with respect to the key holder 11. The key code ring 62 'has a hook shape having a notch 72' so as to divide a part of the rectangle.

  When the lock body 63 enters the notch 72 ′ of the key cord ring 62 ′ by the urging force of the urging spring 64 and abuts against the abutment surface 75, the key cord ring 62 ′ engages with the lock body 63. Therefore, the slide is restricted by the lock body 63. In this locked state, the notch 72 ′ is located inside the key holder 11 and is not exposed to the outside from the key holder 11.

  On the other hand, when the lock body 63 moves against the urging force of the urging spring 64 and moves away from the contact surface 75 by a predetermined distance, the lock body 63 escapes from the notch 72 '. In this state, the key code ring 62 ′ is disengaged from the lock body 63, and the slide is not restricted by the lock body 63. Therefore, in this unlocked state, the key code ring 62 ′ is slid, and at this time, the entire cutout 72 ′ is located outside the key holder 11 and exposed from the key holder 11 to the outside. It becomes possible. That is, the notch 72 ′ of the key code ring 62 ′ can be positioned outside the key holder 11 by being disengaged from the lock body 63 when the connection state where the connection mechanism 61 connects the key 10 is released.

  According to the second embodiment described above, the key code ring 62 ′ removes the key 10 with the key holder 11 when the notch 72 ′ is located inside the key holder 11 and engages with the lock body 63. When the lock body 63 is slid by engaging with the release tool 81, the cutout portion 72 ′ is released from the lock body 63 and can be positioned outside the key holder 11. Thus, the key 10 can be replaced. Thereby, the structure of the connection mechanism 61 is simplified, and connection and release are facilitated.

  In the first and second embodiments described above, the control unit 55 of the key management device 1 communicates with, for example, a management PC (permission management means) at the head office linked with the sales office where the key management device 1 is installed via a LAN. It is also possible to construct a key management system by connecting them so that the function of permitting access to the release tool 81 by the control unit 55 of the key management device 1 can be set by an operation from the management PC. That is, the permission / invalidity of permission for access to the release tool 81 by the control unit 55 of the key management device 1 is set by an operation input. For example, no one can exchange the key 10 for a certain period after the exchange. Or, only a part of the person in charge with specific authority can select the key 10 to be exchanged even for a certain period after the exchange. It becomes.

  Further, in the first and second embodiments, the case where the dedicated storage portion 34 for storing the release tool 81 is described as an example, but an apparatus for storing an ID card managed similarly to the key 10 is provided. A card storage section (not shown) provided separately inside the main body 12 may be used as a storage section for storing the release tool 81. Alternatively, the storage unit 34 can be unitized and attached to the outer surface of the key management device 1.

  In the first and second embodiments, the case where the IC tag reader 87 of the release tool 81 communicates with the control unit 55 by wire is described as an example. However, the IC tag reader 87 may communicate with the control unit 55 wirelessly.
