In addition, an insertion groove 32 into which the identification tag 4 can be inserted from above to below is formed on the back surface of the box portion 3. Further, on the bottom surface of the box portion 3, a latch hole 33 is formed, which can engage and lock the claw hook portion 622 of the locking lever 62 shown in FIGS. Although the size of the storage portion 31 in the box portion 3 can be set freely, in this embodiment, the size can accommodate not only a cylinder lock key but also a card key such as an IC card, a mobile phone, and the like. It is said.

  4A and 4B show the identification tag 4 in this embodiment. FIG. 4A is a front view, FIG. 4B is a rear view, and FIG. 4C is a side sectional view. The identification tag 4 is made of a plate-like member molded of a resin material, and a plurality of code holes 41 are formed on the front side. Further, the lower end portion of the identification tag 4 is cut out obliquely upward from the back side to the front side to form a lower end inclined surface 42. Further, an attachment portion 43 is formed in the vicinity of the upper end portion of the identification tag 4 so as to attach the key K via a string or a chain (see FIG. 2).

  Next, based on FIG. 5 thru | or FIG. 7, a mode that the box part 3 is inserted in the insertion part 22 and locked is demonstrated. FIG. 5 is a diagram showing the insertion portion 22 before the box portion 3 is inserted, and FIG. 6 is a diagram in which the key K is stored in the box portion 3 and the identification tag 4 is attached and inserted into the insertion portion 22. It is a figure which shows the state of. FIG. 7 is a view showing a state where the box portion is completely inserted and locked (the key K is not shown).

  The insertion portion 22 opens in the front direction of the apparatus main body 2 and has an inner shape substantially the same as the outer shape of the box portion 3, and the box portion 3 is completely inserted into the insertion portion 22 and locked (FIG. 7). Then, it is set as the structure which hardly produces a clearance gap between the opening part of the insertion part 22, and the box part 3. FIG. Therefore, in the locked state, it is impossible to take out articles such as keys housed in the box unit 3 from the outside.

  Each insertion portion 22 is provided with a locking / unlocking means 6 for locking and unlocking the inserted box portion 3. In this embodiment, the locking / unlocking means 6 includes a solenoid 61 and a locking lever 62.

  At the time of locking, the locking / unlocking means 6 is in the state shown in FIG. 7, and the rod 611 of the solenoid 61 operates upward (arrow Y in FIG. 7) in response to an unlocking instruction from the locking / unlocking control mechanism 5 (described later).

  The locking lever 62 is pivotally supported around the support shaft 63 in the middle of the rod-shaped member 621, and one end thereof is locked near the tip of the rod 611 of the solenoid 61 by the shaft 64. At the other end, a claw hook portion 622 is formed extending from the tip of the rod-shaped member 621 upward substantially orthogonal to the rod-shaped member 621. An inclined surface 623 that is inclined downward from the back side of the apparatus main body 2 toward the front surface is formed at the tip of the claw portion 622. In addition, the claw portion 622 is inserted into an insertion hole 221 formed in the bottom surface of the insertion portion 22, and when the box portion 3 is taken out and locked, the tip portion is inserted as shown in FIGS. It is in a state of protruding into the portion 22 (at this time, the front side end portion 624 of the claw hook portion 622 also protrudes into the insertion portion 22). Further, at the time of locking, the front end portion of the claw portion 622 is locked in a latch hole 33 formed on the bottom surface of the box portion 3, thereby locking.

  Then, as described above, when the rod 611 of the solenoid 61 moves upward (arrow Y in FIG. 7) according to the unlocking instruction of the locking / unlocking control mechanism 5, the locking lever 62 rotates around the support shaft 63. Thus, the hook part 622 operates downward (arrow Z in FIG. 7). As a result, the latching of the claw portion 622 with respect to the latch hole 31 is released and unlocked.

  In addition, a receiver 7 as shown in FIG. The receiving device 7 includes a plate-shaped tag receiving portion 71 that is arranged to face the identification tag 4 when the box portion 3 is inserted, and the back of the insertion portion 22 with the approximate center of the back surface of the tag receiving portion 71 as a base end ( And a receiving shaft 72 extending in the (back) direction. The distal end of the receiving shaft 72 can be inserted into a hole 222 formed in the back wall of the insertion portion, and the spring body 8 is disposed around the receiving shaft 72. The distance between the two is maintained by pressing the back surface of the tag receiving portion 71.

  Further, on the surface of the tag receiving portion 71 facing the identification tag 4, there is formed a protrusion 73 that has an outer shape substantially the same as the inner shape of the code hole 41 formed in the identification tag 4 and can be inserted into the code hole 41. Has been.

  Accordingly, when the box portion 3 is pushed in the depth direction of the insertion portion 22 from the state of FIG. 6, the protrusion 73 formed on the tag receiving portion 71 is inserted into the corresponding code hole 41, and the tag receiving portion 71 and the identification tag are inserted. The four opposing surfaces abut. At this time, a lower end inclined surface 42 is formed at the lower end of the identification tag 4, and the lower end inclined surface 42 is a lockable means that enables locking. That is, the lower end inclined surface 42 and the inclined surface 623 formed at the tip of the claw hook portion 622 of the locking lever 62 slide with each other, so that the claw hook portion 622 is pushed downward, thereby the box portion 3. Can be further pushed in (see FIG. 9).

  When the box portion 3 is further pushed in, the receiving member 7 is elastically retracted against the urging force of the spring body 8. The claw hook portion 622 of the locking lever 62 is pushed in until the box portion 3 is pushed into the latch hole 33 of the box member 3 until it is locked, whereby a locked state is obtained (FIG. 7).

  At the time of locking, the front plate of the apparatus main body 2 and the front portion of the box portion 3 are flush with each other, so that the box member is withdrawn without permission or the key is stolen. There is nothing. At this time, the position and dimensions of each member are designed so that the claw hook 622 of the locking lever 62 engages with the latch hole 33 of the box member 3. Further, when the front plate of the apparatus main body 2 and the front portion of the box portion 3 are flush with each other, the length of the spring body 8 is minimized, so that the box portion 3 cannot be pushed any further. The position and dimensions of the members are designed.

  Further, a micro switch 55 for detecting that the box portion 3 is inserted and locked is disposed in the vicinity of the back wall of the insertion portion 22, and the detected information is transmitted to the locking / unlocking control mechanism. Has been made.

  Furthermore, the arrangement of the protrusions 73 formed in the tag receiving portion 71 is different for each insertion portion 22 (the same applies to the code hole 41 of the identification tag 4 corresponding to each insertion portion). Therefore, when the box portion 3 is inserted into the wrong insertion portion 22, the projection 73 and the code hole 41 are not encoded, and the opposing surfaces of the identification tag 4 and the tag receiving portion 71 cannot contact each other. Therefore, the box member is in a state where the front plate of the apparatus main body 2 and the front portion of the box portion 3 are flush with each other, that is, until the claw hook portion 622 of the locking lever 62 is engaged with the latch hole 33 of the box member 3. 3 cannot be pushed in and cannot be locked, so that the wrong insertion of the key K is prevented.

  The protrusion 73 formed in the tag receiving portion 71 and the code hole 41 formed in the corresponding identification tag may be changed in arrangement for each insertion portion as described above. In addition, for example, the number of the protrusions 73 and the corresponding code holes 41 may be changed, the shape and size may be changed, or a combination of them may be used.

  By the way, as described above, when the rod 611 of the solenoid 61 moves upward (arrow Y in FIG. 7) according to the unlocking instruction of the locking / unlocking control mechanism 5, the locking lever 62 rotates around the support shaft 63. Thus, the claw portion 622 moves downward, and the claw portion 622 is released from the latch hole 31 and unlocked. The box part 3 is pushed out to the front side. Thereby, the box part 3 can be taken out from the insertion part 22, and the key K and the identification tag 4 accommodated in the box part 3 can be taken out.

  A stopper spring 81 is disposed below each insertion portion 22. The stopper spring 81 is formed by bending one end of a leaf spring into a mountain shape, and the peak portion 811 of the mountain shape is inserted into a hole 223 formed in the bottom surface of the insertion portion 22 so as to protrude into the insertion portion 22. The other end portion is fixed to the lower portion of the insertion portion 22. At the time of locking, as shown in FIG. 6, the mountain-shaped top 811 is pushed downward, but the box 3 is unlocked, and the box 3 is moved toward the front via the support 7 by the elastic force of the spring body 8. When being pushed out, the mountain-shaped top 811 engages with a latch hole 33 formed in the bottom surface of the box 3 (FIG. 6). This prevents the box portion 3 from popping out of the insertion portion 22 and falling off during unlocking.

  On the other hand, when the box portion 3 is to be inserted into the insertion portion 22 with the key K and the identification tag 4 removed from the box member 3, as shown in FIG. It is made to abut against the nail | claw part 622 (front side edge part 624). Therefore, the box portion 3 cannot be pushed any further and cannot be locked. Therefore, it can be easily confirmed that the key K of the room corresponding to the insertion portion 22 has been taken out.

  By the way, the identification tag 4 that can be inserted and locked only in the insertion portion 22 assigned in advance is not limited to the above embodiment. For example, an electronic tag is provided in place of the code hole 41 provided in the identification tag 4, and a reader for reading information stored in the electronic tag is provided in place of the protrusion 73 of the receiver 7. The box unit 3 (and the identification tag 4) may be verified as to whether or not the correct insertion unit 22 is inserted.

  Next, an example of the device configuration of the locking / unlocking control mechanism 5 in this embodiment will be described with reference to FIG. In FIG. 11, reference numeral 5 denotes a locking / unlocking control mechanism, which includes a liquid crystal display unit 51, an input key 52, a personal authentication device 53, a storage means 54, a micro switch 55, and a control unit 56 for controlling and managing these devices. ing. The storage means 54 includes information such as an ID or address assigned to each room (each insertion unit 22), information such as an ID and password assigned to the corresponding identification tag 4, and a user of each room. Are stored in association with IDs and passwords assigned to the user, finger vein information data of each user, and the like, and programs necessary for control and management of the key management apparatus 1 are stored.

  In the locking / unlocking control mechanism 5, a user inputs a room number (a number assigned to the insertion unit 22), an ID assigned to the user, and the like to the input key 52 and the personal authentication device 53. When the personal information of the user is acquired by the device 53, the input / acquired information and the information stored in the storage means 54 are collated. When this verification confirms the identity of the user and confirms (authentication) that the user has the right authority to take out the key of the room number, the control unit 56 sends the insertion unit 22 to the locking / unlocking means 6. An unlocking instruction is transmitted. As a result, the locking / unlocking means 6 operates, the predetermined insertion portion 22 is unlocked, the box portion 3 inserted in the insertion portion 22 is pushed out to the front, and the key K accommodated in the box portion 3 is accommodated. Can be taken out together with the identification tag 4.

  Further, when the box portion 3 to which the identification tag 4 corresponding to the unlocked insertion portion 22 is attached is correctly inserted and locked, the microswitch 55 detects this and the locking information is sent to the locking and unlocking control mechanism 5. Is transmitted and stored.

  Note that the device configuration of the locking / unlocking control mechanism 5 according to the present invention is not limited to the above-described configuration. For example, the authentication information necessary for the unlocking and the authentication procedure (flow) are arbitrarily set as necessary. It can be modified and the required equipment can be included as a configuration accordingly.
