Embodiment 1 FIG.
With reference to FIGS. 1-8, the structure of the key management apparatus 100 which concerns on Embodiment 1 of this invention is demonstrated.
As shown in FIGS. 1 to 7, the key management device 100 includes a key management device main body 10 having a substantially rectangular parallelepiped shape and a plurality of key holders 1. As shown in FIG. 1, the key management device body 10 is used in a state of being placed upright on a horizontal surface such as a desk. In such a use state, the height direction of the key management device main body 10 (direction perpendicular to the mounting surface of the key management device 100) is H, the depth direction is W, and the width direction is L. Further, the front side of the key management device body 10 is FR, the back side is BK, the top side is TP, the bottom side is BT, the right side is RS, and the left side is LS. The key holder 1 is a member to which a key (not shown) whose use is managed by the key management device 100 is attached.

  The key management device main body 10 includes a key holder holding portion 2 on the upper left side as viewed from the front side FR and an operation means 4 on the right side. The key holder holding unit 2 holds a plurality of key holders 1. A key exchanging unit 30 is provided adjacent to the operating means 4 at the lower left side when viewed from the front side FR of the key management device body 10, that is, below the key holder holding unit 2. The key holder 1 to which the key to be exchanged is attached can be inserted into the key exchange unit 30 during the key exchange operation. The key holder holding unit 2 and the key exchange unit 30 are configured so as to be covered with an outer panel (not shown). Further, an approximately arch-shaped handle 11 that is gently curved is provided on the upper surface of the key management device body 10. Further, as shown in FIG. 6, support legs 12 are provided at the four corners of the bottom surface of the key management device main body 10.

  The key holder holding part 2 is provided with a key holder insertion part 20 into which a plurality of key holders 1 are inserted in parallel along the height direction H for three stages. Each of the key holder insertion portions 20 is a band-shaped projecting portion having a substantially right triangle in cross section (see FIG. 3). The substantially right triangle of the cross section of the key holder insertion portion 20 is formed in a shape such that the long side is obliquely upward and the short side is obliquely downward, and the long side portion defines the key holder insertion surface 22. It is composed. Thereby, the key holder insertion surface 22 is formed as an inclined surface that faces obliquely upward when the key management device 100 is placed upright on a horizontal surface. That is, each of the key holder insertion surfaces 22 is an inclined surface that is inclined at a predetermined inclination angle Θ with respect to the height direction H so as to be positioned on the near side from the upper end toward the lower end. In addition, the inclination | tilt angle (theta) of the key holder insertion surface 22 is 25-30 degrees, respectively. In addition, ten key holder insertion holes 21 for inserting the key holder 1 are provided on the respective key holder insertion surfaces 22 along the width direction L at intervals from each other. The key holder insertion hole 21 is formed such that the key holder 1 is inserted from the front side FR of the key management device main body 10 obliquely downward I, that is, in a direction perpendicular to the key holder insertion surface 22. That is, the key holder insertion hole 21 is formed in a direction I that is inclined with respect to the height direction H. The key holder insertion hole 21 is fitted with an engagement means 24 that locks the key holder 1 so that it is not pulled out by being engaged with the key holder 1 when the key holder 1 is inserted into an appropriate position.

  The operating means 4 has a first inclined surface 4a and a second inclined surface 4b that are formed in parallel in two levels along the height direction H. The first inclined surface 4a is located above the operation means 4, and is formed as an inclined surface that faces obliquely upward when the key management device 100 is placed upright on a horizontal surface. That is, the first inclined surface 4a is an inclined surface that is inclined at a predetermined inclination angle with respect to the height direction H so as to be positioned on the near side from the upper end toward the lower end. A step surface 43 is formed at the lower end of the first inclined surface 4a, and the step surface 43 extends from the near side to the far side in the depth direction W. A second inclined surface 4b is formed below the first inclined surface 4a with the step surface 43 interposed therebetween. Similar to the first inclined surface 4a, the second inclined surface 4b is formed as an inclined surface that faces obliquely upward when the key management device 100 is placed upright on a horizontal surface. That is, the second inclined surface 4b is an inclined surface that is inclined at a predetermined inclination angle with respect to the height direction H so as to be positioned on the near side from the upper end toward the lower end.

  On the first inclined surface 4 a of the operating means 4, a display panel 40 is provided on the left side when viewed from the front side FR, and a contact card reader 41 is provided on the right side so as to be adjacent to the display panel 40. The display panel 40 displays, for example, information such as the type of operation that can be performed by the user (such as a use operation for using a key and an exchange operation for exchanging a key), an operation procedure, and an operation result. Is to do. The display panel 40 is configured by a touch panel or the like, and also serves as an input unit for inputting information such as designation of an operation type performed by a user. In the operation means 4, the display panel 40 is provided on the first inclined surface 4 a that is inclined obliquely upward, so that the user can more easily see the display panel 40 and the convenience of operation is improved. To do.

  The contact-type card reader 41 has a card insertion groove 41a extending from the upper end to the lower end of the first inclined surface 4a, and reading means (not shown) for reading information on the card passed through the card insertion groove 41a. Is included. Here, since the step surface 43 is formed at the lower end of the first inclined surface 4a, the lower end of the card insertion groove 41a is opened. The bottom of the card insertion groove 41a is formed in parallel with the first inclined surface 4a. Therefore, when the card information is read by the contact-type card reader 41, the card can be smoothly pulled out from the upper end to the lower end in a diagonally downward direction along the bottom of the card insertion groove 41a, thereby improving operability. .

  Further, a non-contact card reader 42 is provided on the second inclined surface 4 b of the operation means 4. The non-contact type card reader 42 has a planar reading means 42a and a support part 42b which is a belt-like protrusion having a rectangular cross section, and the support part 42b is formed below the reading means 42a. The reading unit 42a reads information on the cards superimposed on the reading unit 42a. The support part 42b supports the cards stacked on the reading unit 42a. Moreover, since the card | curd after passing the contact-type card reader 41 can be temporarily set | placed on the support part 42b, operativity improves. In addition, even while the display panel 40 is being operated, the user performs work while confirming the location of the card in front of the user, leading to improved security.

  Furthermore, when using a non-contact type card reader, usually, the card information is once read by the card reader and then the operation is performed, and the user presses the clear key or does not perform the operation for a certain period of time. After a lapse, the operation ends with a timeout. However, in such a case, if the user forgets to press the clear key, there is a possibility that another user can perform an operation immediately after that. On the other hand, in the non-contact type card reader 42 of the key management device 100 according to this embodiment, the card can be placed on the support part 42b during the operation, so the card information is always read by the reading means 42b. It is possible to adopt a system that performs operations while letting In such a system, when the user removes the card from the support portion 42b, the operation authority is lost, and the operation is terminated. Accordingly, there is no danger that another person can operate as it is because the user forgets to press the clear key, and the security is improved.

Next, a method for using the key management apparatus 100 will be described.
Usually, the key holder 1 to which the key is attached is locked by the engaging means 24 in a state where the key holder 1 is inserted into the key holder insertion hole 21 of the key holder holding portion 2 and cannot be pulled out. Here, when the user intends to use one of the keys, the card information is first read by the contact card reader 41 or the non-contact card reader 42. Based on the read information, the authority given to the user having the card is confirmed. When the user is authorized to use either key, the lock between the key holder 1 to which the usable key is attached and the engaging means 24 is released. Thus, the user can pull out the key together with the key holder 1 from the key holder insertion hole 21 and use it.

  Further, after the user uses the key, the key holder 1 is inserted again into the corresponding key holder insertion hole 21. Here, the key holder insertion surface 22 in which the key holder insertion hole 21 is formed is an inclined surface formed to face obliquely upward. The key holder insertion hole 21 is formed in a direction perpendicular to the key holder insertion surface 22, that is, in a diagonally downward direction I that is inclined with respect to the height direction H. Therefore, as shown in FIG. 3, the key holder 1 is inserted in the diagonally downward direction I. The key holder 1 is engaged by the engaging means 24 and locked so that it cannot be pulled out unless a certain releasing operation is performed again.

Next, the moment M1 that acts on the key management device body 10 by the user's force when the user inserts the key holder 1 into the key holder insertion hole 21 will be described with reference to FIG. The moment M1 is a moment that works counterclockwise on the paper surface of FIG. 8 with the support leg 12 on the back side as the rotation center R. If this moment M1 is large, the key management apparatus 100 may fall backward.
When the user inserts the key holder 1 in the diagonally downward direction I with the force of P1 [N] in the key holder insertion portion 20 at the top of the key holder holding portion 2, the line of action and the center of rotation of the force P1 The distance from R is D1 as shown in FIG. Accordingly, a moment of M1 = P1 · D1 [N · m] acts on the rotation center R counterclockwise on the paper surface of FIG. On the other hand, if the key holder insertion surface 22 is not an inclined surface but is formed parallel to the height direction H, the key holder insertion hole 21 is formed perpendicular to the height direction H, and the user can Must be inserted horizontally into the key holder insert. In this case, since the height of the key holder insertion hole 21 of the key holder insertion portion 20 at the uppermost stage is D2, the counterclockwise moment M2 = P1 · D2 [N · m] works. Here, since D1 is shorter than D2, even if the user inserts the key holder 1 into the key holder insertion hole 21 with the same force, the moment M1 is smaller than the moment M2.

As described above, the key holder insertion hole 21 of the key holder insertion surface 22 is formed so that the key holder 1 is inserted in the diagonally downward direction I from the front side FR of the key management device body 10. The moment M1 acting on the key management device 100 is reduced by the force when the key is inserted. That is, it becomes difficult for the key management device 100 to fall backward. Therefore, it is not necessary to support the key management device 100 with a stopper or the like, and the key holder 1 can be inserted while being kept upright, so that a large work space is not required. Therefore, the user can easily work in a limited work space.
Further, since the key holder insertion surface 22 provided with the key holder insertion hole 21 is inclined so as to face obliquely upward in the key management device main body 10, the key holder insertion is performed when the user inserts the key holder 1. The holes 21 are easy to see, and the convenience of work is improved.

In addition, the key holder insertion surface 22 can also be formed as an inclined surface facing diagonally downward. A key management apparatus 200 having a key holder insertion surface 22 ′, which is a modification of the key holder insertion surface 22, will be described with reference to FIG. In the following description, the same reference numerals as those in FIGS. 1 to 8 are the same or similar components, and thus detailed description thereof is omitted.
The key holder insertion part 20 ′ of the key holder holding part 2 ′ of the key management apparatus 200 has a band shape with a substantially right triangle in cross section, similar to the key holder insertion part 20 of the key management apparatus 100 according to the first embodiment. It is a protruding part. The substantially right triangle of the cross section of the key holder insertion portion 20 ′ is formed in a shape such that the long side faces obliquely downward and the short side faces obliquely upward, and the long side portion is the key holder insertion surface 22. Make up. Thus, the key holder insertion surface 22 ′ is formed as an inclined surface that faces obliquely downward when the key management device 100 is placed upright on a horizontal surface. That is, the key holder insertion surface 22 ′ is an inclined surface that is inclined at a predetermined inclination angle Θ ′ with respect to the height direction H so as to be positioned on the near side from the lower end toward the upper end. The key holder insertion hole 21 is formed so that the key holder 1 is inserted obliquely upward I ′ from the front side FR of the key management device body 10 ′, that is, in a direction perpendicular to the key holder insertion surface 22 ′. Is done. That is, the key holder insertion hole 21 ′ is formed in a direction I ′ that is inclined with respect to the height direction H. Similarly to the engagement means 24 of the first embodiment, an engagement means 24 ′ that locks the key holder 1 so as not to be pulled out is attached to the key holder insertion hole 21 ′.

  As described above, since the key holder insertion hole 21 ′ is formed so that the key holder 1 is inserted in the obliquely upward direction I ′, the key holder 1 is not sufficiently locked by the engaging means 24 ′. The key holder 1 slides down from the key holder insertion hole 21 'according to gravity. Therefore, in the key management device 200, it can be easily confirmed that the key holder 1 is sufficiently locked by the engaging means 24 'inside the key management device main body 10', leading to an improvement in security.
