DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described by way of embodiments with reference to the accompanying drawings. FIG. 1 is an overall view showing an embodiment of the present invention. A key 4 is attached to the inside of a box 1 via a chain 5, and the lid 2 is not closed until the key 4 is returned to the inside of the box 1. It has become.

A cover 2 is rotatably mounted on the box 1 and a cover opening / closing mechanism 3 is provided. The cover opening / closing mechanism 3 is connected to a reading control circuit 13 built in the box 1. I have.

At the front of the box 2, an inlet 8 and a return port 9 are provided above and below, respectively, with both being exposed to the outside.

As shown in FIG. 1, the inlet 8 to the return port 9 are formed by a vertically continuous pipe line, whereby the ID provided in the box 1 in the vertical direction is formed. A tag passage 10 is configured.

When the ID tag passage 10 is viewed from the side, the upper and lower portions are bent in a fan shape, and the central portion is straight in a rectangular shape.

On the other hand, the non-contact ID tag 6 is a personal identification means for opening the lid 2 and taking out the key 4, and is formed, for example, in a coin shape (FIG. 1), and has an ID 7 recorded therein. .

The thickness t and the diameter D of the coin-shaped non-contact ID tag 6 (FIG. 1) are slightly smaller than the width W and the height H of the insertion port 8 and the return port 9 of the ID tag passage 10. I have.

The entire system is controlled by giving instructions to each device such as C.

As described above, the ID reading section 11B makes contact with the pin 11A (FIG. 1) and holds the non-contact ID.
The ID 7 of the tag 6 is read by electromagnetic coupling.

However, in this case, the method of reading the ID 7 is not limited to the electromagnetic coupling, and for example, a bar code or the like printed on the surface of the non-contact ID tag 6 may be used.

The ID tag holding mechanism controller 13C
It is connected to an ID tag holding mechanism 11 composed of the pin 11A (FIG. 1) and a solenoid 11B, and controls the ID tag holding mechanism 11.

That is, the ID tag holding mechanism controller 13
When the non-contact ID tag 6 falls in the ID tag passage 10 and hits the pin 11A and is suspended (step 102 in FIG. 4), the micro switch 11C is switched to the micro switch 11C (FIG. 1).
Through the control unit 13A (FIG. 3).
The D reading unit 13B is controlled so that the ID 7 of the non-contact ID tag 6 is read (Step 103 in FIG. 4).

The ID tag holding mechanism controller 13
C indicates that the lid 2 is locked (step 1 in FIG. 4).
07), this is detected via a lid opening / closing mechanism control unit 13D, which will be described later, and the ID tag holding mechanism 11 is activated to operate the pin 11A
(Step 108 in FIG. 4), the non-contact ID tag 6 is dropped in the ID tag passage 10 and returned (step 109 in FIG. 3).

The lid opening / closing mechanism controller 13D is connected to the lid opening / closing mechanism 3 (FIG. 1) and controls it.

That is, the lid opening / closing mechanism controller 13D
As described above, when the ID 7 of the non-contact ID tag 6 matches the registered ID 12 and is legitimate (YES in step 104 in FIG. 4), the lid opening / closing mechanism 3 (FIG. 1) is operated to operate the lid. 2 (step 105 in FIG. 4) and its lid 2
(FIG. 1) is opened so that the key 4 can be taken out (in parentheses in FIG. 4).

The lid opening / closing mechanism controller 13D includes:
Micro switch 3A constituting lid opening / closing mechanism 3 (FIG. 1)
When it is detected that the lid 2 is closed (YES in step 106 in FIG. 4), the lid opening / closing mechanism 3 is operated to lock the lid 2 (step 107 in FIG. 4).

The storage unit 11E registers the ID 12 (FIG. 3) in advance, and the registered ID 12 is used for collation determination of the ID 7 of the non-contact ID tag 6 (step 1 in FIG. 4).
04).

The operation of the key storage device shown in FIG. 1 having the above configuration will be described below.

(1) Operation from when the non-contact ID tag 6 is inserted until the lid 2 is unlocked.

In step 101 of FIG.
The D tag 6 is inserted from the input port 8, and in step 102, the non-contact ID tag 6 falls in the ID tag passage 10,
It is suspended after hitting the pin 11A.

That is, when the non-contact ID tag 6 is inserted from the input port 8 (FIG. 1), the non-contact ID tag 6 falls along the ID tag passage 10 by its own weight.

Therefore, the non-contact ID tag 6 easily falls in the ID tag passage 10 by its own weight only, and
No special mechanism for forcibly dropping and transporting the tag 6 is required.

When the non-contact ID tag 6 falling in the ID tag passage 10 hits the pin 11A, the non-contact ID tag 6
The tag 6 is interposed between the inner walls of the ID tag passage 10 and locked and held.

Therefore, a special mechanism for locking the non-contact ID tag 6 is unnecessary.

Next, in step 103 of FIG.
The ID 7 of the non-contact ID tag 6 is read, and
At 4, it is determined whether or not the ID 7 matches the registered one.

That is, when the non-contact ID tag 6 hits the pin 11A and is suspended (step 102 in FIG. 4),
The ID tag holding mechanism controller 13C detecting this through the microswitch 11C (FIG. 1) (FIG. 3) activates the ID reading unit 13B via the control unit 13A (FIG. 3).

As a result, the ID reading section 13B reads the ID 7 of the non-contact ID tag 6 by electromagnetic coupling, compares the ID 7 with the ID 5 registered in advance in the storage section 11E (FIG. 3), and determines whether the two match. Is determined.

In this case, according to the present invention, since the non-contact ID tag 6 is used as the ID tag, a contact mechanism for reading the ID 7 to the ID reading unit 13B is not required.

Then, in step 104 of FIG.
If both match, that is, if it is determined that ID7 (FIG. 1) is legitimate (YES), in step 105, the lid 2
Is unlocked.

That is, when the ID 7 is normal (YES in step 104 in FIG. 4), the control unit 13A controls the lid opening / closing mechanism controller 13D (FIG. 3) to control the lid opening / closing mechanism 3
By actuating (FIG. 1), the lid 2 is unlocked.

Thus, the lid 2 (FIG. 1) is opened and the box 1 is opened.
The key 4 can be taken out from the inside (in parentheses in FIG. 4).

In this case, the non-contact ID tag 6
A is held pending (step 102 in FIG. 4) and is taken as security.

In step 104 of FIG. 4, the read ID 7 (FIG. 1) and the registered ID 12 (FIG. 3)
If the IDs do not match, that is, if it is determined that the ID 7 is invalid (NO), the process proceeds to step 108, where the pin 11A is pulled in, the non-contact ID tag 6 is dropped, and returned via the return port 9 (FIG. 1). .

In this case, the lid 2 remains locked (locked) and cannot be opened.

(2) Non-contact ID tag 6 after closing lid 2
Operation until is returned.

In step 106 of FIG. 4, it is determined whether or not the lid 2 is closed. If it is determined that the lid 2 is not closed (NO), the same operation is repeated, and if it is determined that the lid 2 is closed, (YES), in step 107, the lid 4 is locked (locked).

That is, the control section 13A (FIG. 3) controls the lid opening / closing mechanism 3 (FIG. 1) via the lid opening / closing mechanism controller 13D, and determines whether or not the lid 2 is closed by the microswitch 3A (FIG. 1). When it is detected that the lid 2 is closed, the lid 2 is locked by operating the lid opening / closing mechanism 3.

Next, in step 108 of FIG.
When the pin 11A is pulled in, the reserved non-contact ID tag 6 falls in the ID tag passage 10, and in step 109, the non-contact ID tag 6 is returned from the return port 9.

That is, the ID tag holding mechanism controller 13
C (FIG. 3), when the lid 2 is locked (step 107 in FIG. 4), the lid is opened and closed by the lid opening / closing mechanism controller 13D.
And the solenoid 1 of the ID tag holding mechanism 11
1B is energized (FIG. 2B), and the pin 11A is pulled in.

As a result, the ID tag holding mechanism 11
The non-contact ID tag 6, which has been retracted from the tag passage 10 and hit the pin 11A, is dropped in the ID tag passage 10 by its own weight (FIG. 2B).

The non-contact ID tag 6 that has fallen in the ID tag passage 10 is returned from the return port 9 (FIG. 1).

As described above, the non-contact ID tag 6 which has been kept as security returns the key 4 (FIG. 1) to the inside of the box 1 and
The key 4 is returned only after it is confirmed that the key 4 has been closed, so that forgetting to return the key 4 is prevented.

The ID tag holding mechanism controller 13
C (FIG. 3), after the pin 11A is retracted (FIG. 2).
(B)) After a certain period of time, the pin 11A is returned to the original position by stopping the energization of the solenoid 11B by controlling the ID tag holding mechanism 11 (FIG. 1) (FIG. 2).
(A)), preparing for the next insertion of the non-contact ID tag 6.

[0072]

As described above, according to the present invention, the ID tag holding mechanism can be simplified by forming the ID tag holding mechanism with the pin and the solenoid, and the security can be secured if the key is not returned. Since the non-contact ID tag set as above is not returned, there is an effect that forgetting to return the key is prevented.

Further, the ID of the non-contact ID tag held against the pin is read to determine whether the ID is valid or not.
Since the D-verification communication is performed in a closed space inside the box of the key storage device, it is difficult to read the communication content from the outside, and there is also an effect that security can be improved.
