[Prior art]
Conventionally, as this type of management apparatus, for example, an embodiment shown in FIG. 9 is known. That is, reference numeral 50 denotes an apparatus main body, and the apparatus main body 50 is provided with a plurality of key storage sections 51 aligned in the vertical and horizontal directions. Each key storage portion 51 is formed in a box shape, and an opening / closing door 53 is pivotally mounted on a front surface of the panel 52.
[0003]
Reference numeral 54 denotes a lock device for a key 55 provided in each key storage unit 51. A required space 56 is provided between the front surface 54a of the key lock device 54 and the opening / closing door 53 so that a hand can be inserted and the key 55 can be pulled out of the lock device 54.
[0004]
Reference numeral 57 denotes a control device that is provided in the device main body 50 or the manager's office and controls each of the key lock devices 54. The control device 57 is electrically connected to a display device 58 provided inside the device main body 50 and a card reader 59 provided at the center of the device main body 50.
[0005]
In the above configuration, when a magnetic card (not shown) is inserted into the card insertion slot of the apparatus main body 50, the card reader 59 reads the contents of the card and sends the identification information to the control device 57. The control device 57 causes the determining unit 60 to determine whether the magnetic card is a legitimate one, and which key storage unit 51 matches the contents of the magnetic card, and to determine the contents of the magnetic card and the registration information of the memory unit 61. When they match, the indicator lamp of the display device 58 is turned on, the lock of the key lock device 54 of the key storage unit 51 corresponding to the contents of the card is unlocked, and the opening / closing door 53 is automatically opened.
[0006]
Then, the user puts his hand in the required space 56 of the key storage unit 51, first turns the key 55 in the unlocking direction, and then pulls out the key from the key lock device 54.
[0007]
However, the above configuration has the following drawbacks.
(1) When the key 55 is pulled out from the lock device 54, the hand must be put into the required space 56 and the key 55 must be turned to the unlocking position while holding the key 55, so that the operation is troublesome.
(2) Since the required space (space) 56 must be provided in the key storage section 51, the depth D of the apparatus main body 50 is increased. In other words, the space in the key storage cannot be effectively utilized, so that the apparatus body cannot be made compact.
[0008]
[Problems to be solved by the invention]
In view of the above-mentioned conventional drawbacks, the present invention is very easy for a user to use, and only a predetermined key is stored in a key storage body from the viewpoint of management convenience or prevention of mischief. It is another object of the present invention to provide a key management device that can effectively utilize the space described above and can provide a large number of key housings in the device body while effectively utilizing a predetermined front panel.
[0009]

[Action]
When the user inserts the identification card into the card insertion slot of the apparatus main body, the input device sends the contents of the identification card to the control device. The control device outputs the transmitted information signal to the determination unit. If the identification card is correct, the determination unit determines the key storage body corresponding to the card content for which the collation match was obtained, and notifies the control device of the determination result. The control device outputs a drive signal to the drive device selected based on the determination result.
[0013]
Then, the polarity is changed via the power supply of the driving device to extend the operating rod, and as a result, the key housing is rotated by a required amount to the outside of the device main body and the opening of the front panel is opened. Therefore, the key stored in the key storage body can be extracted from the keyhole. When the key is removed from the key housing, the key housing automatically returns to the closed position.
[0014]
【Example】
Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. 1 to 7, reference numeral 1 denotes a box-shaped device main body. The depth of this device body is generally shallower than this type of device body. Reference numeral 2 denotes a front panel of the apparatus main body 1. Except for a part on the right side, the front panel 2 has vertically elongated openings 3 formed in a vertically and horizontally aligned state (lattice form). The number of openings 3 is 50 in total, but this number can be increased or decreased as needed.
[0015]
In the apparatus main body 1, a plurality of key housings 4 each closing the opening 3 and having a front wall substantially perpendicular to the front panel 2 are rotatably supported. ing. Further, the apparatus main body 1 has a control device 5 for outputting a control command signal to open and close the opening 3 with respect to the front panel 2 based on the front panel 2, based on the control command signal from the control device 5. A plurality of driving devices 6 and the like, which are driven and open / close each key housing 4 directly or indirectly, are incorporated. Further, the control device 5 includes a card reader 7 as an example of an input device that is input by a user of the key (insertion of an identification card, input operation of a personal identification number, etc.), A display unit 8 for displaying whether or not to be stored in the storage unit 4 is electrically connected.
[0016]
Therefore, the key housing 4 as a main part of the present invention will be described first. As shown in FIGS. 1 to 4, the key housings 4 are individually arranged in the vertical direction, and form part of a door for each key housing provided on the front panel 2. .
[0017]
That is, the key housing 4 is formed in a vertically long shape having the front wall 4a which is substantially the same vertical surface as the front panel 2. The key housing 4 is rotatably supported by a vertically elongated opening 3 of the apparatus main body 1 via a horizontal shaft 11. The rear wall 4b of the key housing 4 is slightly shorter than the front wall 4a. The left and right side walls 4c of the key housing 4 are formed shorter than the rear wall 4b. Further, a keyhole 13 into which a predetermined key K can be inserted is formed on the upper wall 4e of the key housing 4. The keyhole 13 has a function of guiding the insertion portion 14b connected to the knob 14a of the key K, and does not pass through the key K unless the shape (blade, groove) of the insertion portion 14b of the key K matches. Therefore, when the insertion portion 14b of the key K matches the keyhole 13, the key K is stored in the key storage body 4 in such a manner that the knob portion 14a protrudes from the upper wall 4e of the key storage body 4.
[0018]
The driving device 6 is disposed behind the key housing 4 as shown in FIG. As an example of the driving device 6, a magnet motor in which the operating rod moves forward and backward in the axial direction of the motor body is used.
[0019]
By the way, the structure of the magnet motor 6 will be briefly described with reference to FIG. 5. Reference numeral 15 denotes a motor body fixedly and laterally mounted on the inner frame 12 so as to be located behind the key housing 4. A magnet 16 is fixedly provided in the inner peripheral portion of the motor body 15, and a cylindrical rotor 17 is provided inside the magnet 16. Reference numeral 18 denotes a center guide tube that supports the rotor 17, and an operating rod 19 that moves forward and backward in the axial direction of the motor body 15 is slidably fitted in the center guide tube 18. The operating rod 19 has its tip 19a pivotally attached to the central portion of the rear wall 4b of the key housing 4 (including the portion from the central portion), and moves forward and backward when the polarity of the power supply for the driving device is switched. . Therefore, this magnet motor 6 is different from a general motor in which the output shaft rotates, and may not be originally called “motor”. However, in this specification, the output shaft (operating rod) is the shaft of the motor main body. A magnet type driving device that moves forward and backward in the core direction is referred to as a “magnet motor” for convenience.
[0020]
Next, the control device 5 will be described. Although the control device 5 is appropriately incorporated in the apparatus main body 1 in the present embodiment, it is not always necessary to mount the control device 5 on the apparatus main body 1 and may be arranged in, for example, a management room.
[0021]
As shown in FIG. 7, a card reader 7 as an example of an input device which is input by a key user (insertion of an identification card, input operation of a personal identification number, etc.) is electrically connected to the main body 1 of the apparatus. ing. Therefore, a card insertion slot 20 for an identification card (an ID card, a card having a barcode, etc.) is provided at an appropriate position on the front panel 2 of the apparatus main body 1 corresponding to the position of the input device 7. Of course, as another example of the input device 7, a so-called ten-key may be provided separately or in combination.
[0022]
The control unit 5 is electrically connected to a display unit 8 for displaying which key storage unit 4 should store the key of the user, which key storage unit 4 is stored in the key storage unit 4, and the like. Therefore, lighting lamps 21 are provided at appropriate positions on the front panel 2 of the apparatus main body 1 in accordance with the number of key housings 4. Further, each magnet motor 6 horizontally provided in each opening 3 of the apparatus main body 1 is electrically connected to the control device 5 via each power supply 22 for polarity conversion. Reference numeral 23 denotes a memory unit provided with a program necessary for operating the apparatus, 24 denotes a judgment unit for comparing input signals from the input device 7 with registered information in the memory unit, and 25 denotes a key for the user. Is a timer circuit that keeps the key storage unit 4 open for a required time when the key storage unit 4 is removed from the key storage unit 4.
[0023]
In the above configuration, one mode in which the user takes out the key stored in the key storage body 4 will be described.
[0024]
First, the user inserts the identification card into the card insertion slot 20 of the apparatus main body 1. Then, the input device 7 sends the contents (identification information) of the identification card to the control device 5. Control device 5 outputs the transmitted information signal to determination unit 24. The determination unit 24 compares and compares the registration information set and registered in advance in the memory unit 23 with the card contents (identification information) read by the card reader 7 as an input device, corresponding to each key housing 4, and performs the identification. If the card is correct, the key storage unit 4 corresponding to the content of the card whose collation match is obtained is determined, and the determination result is notified to the control device 5. The control device 5 outputs a drive signal to the selected magnet motor 6 based on the determination result. Then, the polarity of the magnet motor 6 is changed via the power supply 22, and the operating rod 19 is extended.
[0025]
Next, when the operating rod 19 of the magnet motor 6 is extended, as shown in FIG. 6, the key housing 4 rotates a required amount (in the embodiment, 25 degrees) outside the apparatus main body 1 about the horizontal axis 11 as a fulcrum. Thereby, the opening 3 of the front panel 1 is opened. At this time, the timer circuit 25 for opening the key housing 4 for a required time starts.
[0026]
Then, the user pulls out the key K from the keyhole 13 of the key storage body 4 with his finger. After the user removes the key K from the key housing 4 in this way, the control device 5 sends a signal to the drive device side after the timer of the timer circuit 25 ends. Then, the polarity of the power supply 22 is switched, the operating rod 19 of the magnet motor 6 expands and contracts, and the key housing 4 returns to the original position. When the key storage body 4 returns to the original position, the front wall 4a thereof becomes the same vertical plane as the front panel 2.
[0027]
In the above embodiment, the description has been given of the case where the key housing 4 returns to the original closed position after the timer of the timer circuit 25 ends. However, it is not always necessary to use the timer circuit 25. A switch for closing the key housing 4 such as a push button may be provided on the panel 2, and this switch may be electrically connected to the control device. Further, an internal detector for detecting whether or not a key is stored can be appropriately mounted on the key housing 4, and the internal detector can be connected to the control device to automatically close the key housing 4. You may do it.
[0028]
Further, in the above-described embodiment, the opening 3 of the front panel is formed in a vertically long shape, and it is described that the key is to be inserted into the vertically long key storage body 4. However, as shown in FIG. It may be horizontally long. Therefore, in this case, the key housing 4A is inevitably a drawer type. For example, the key housing 4A is slidably supported by the apparatus main body 1A via the guide portion or the guide member 26, and the key hole 13A is provided. Is formed on the side wall 27 of the key housing 4A, and the key housing 4A opens and closes with reference to the front panel 2A by the forward and backward movement of the operating rod 19A of the driving device 6A. In the case of this embodiment, the bottom wall 28 of the key housing 4A arranged in the lateral direction protrudes so as to support the knob 14a of the key K.
[0029]
In the case of the modification of the first embodiment, the key housing 4A horizontally provided in the opening 3A is slidably supported by the apparatus main body 1A via a guide portion or a guide member 26. However, it is not always necessary to use the “pull-out type”, and the key housing may be pivotally supported on the apparatus body in a state where the key storage body is laid down as in the first embodiment (horizontal type in the first embodiment).
[0030]
【The invention's effect】
As is clear from the above description, the present invention has the following effects.
(1) When inserting a key into the key housing, it is sufficient to simply insert the key into the keyhole of the key housing, while when removing the key from the key housing, the key stored in the key housing is directly extracted. Just good. Therefore, it is very easy for the user to use.
(2) Moreover, since a keyhole into which only a predetermined key can be inserted is formed on one side wall of the key housing, there is no fear that another key is accidentally inserted into the key housing. The risk of the key housing itself being mischievous is also reduced. Therefore, management convenience and the like can be exhibited.
(3) Since the front wall of the key housing forms a part of the front panel, so to speak, the space of the key housing can be effectively utilized. Therefore, the depth of the apparatus main body can be reduced (the apparatus main body can be made compact).
(4) Since the key housing is housed in the apparatus main body so that the opening formed in the front panel can be closed, a large number of keys can be stored in the apparatus main body while effectively utilizing the front panel of a predetermined size. A body can be provided.
(5) Since the driving device is disposed in the horizontal direction, and the operating rod connected to the rear wall of the key housing moves forward and backward in the axial direction of the motor body, the unlocking or locking mechanism is not required (configured). Since the number of parts is reduced), manufacture is easy.
