FIG. 1 is an overall view showing an embodiment of the present invention. The present invention is configured by a key storage device 13 and a remote control device 12.

The key storage device 13 stores the key 4 in the box 1 and the cover 2
The remote control device 12 is operated when the cover 2 is opened and the key 4 is taken out of the box 1.

The key storage device 13 (FIG. 1) has a box 1 and a lid 2, and inside the box 1, a key 4 is attached via a mooring means such as a chain 5.
The lid 2 is not closed until the key 4 is returned to the box 1.

Therefore, in order to close the lid 2, it is necessary to return the key 4 before that. As described below, according to the present invention, by preventing the lid 2 from being forgotten to be closed,
This prevents forgetting to return the key.

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 control circuit 11 (FIGS. 1 and 2) described later. Have been.

A button 9 (FIG. 1) for operating a reception start switch 11F (FIG. 2) described later is provided on the front surface of the box 1 (FIG. 1).

The remote control device 12 (FIG. 1) is a device operated when the key 2 is removed by opening the lid 2 of the key storage device 13 (FIG. 1), and has a case 6.

In this case 6, a control circuit 10 (FIGS. 1 and 2) is built in, a button 7 for operating a transmission switch 10A (FIG. 2) to be described later, and a sound which is a kind of alarm AL. A speaker 8 for outputting a warning sound such as a melody or the like is provided.

The control circuit 10 of the remote controller 12 (FIG. 2) includes a transmission switch 10A, an ID code transmission means 10B, an alarm start / stop signal receiving means 10D, and an alarm means 10E.

When the transmission switch 10A is pressed (step 101 in FIG. 3), the ID code transmission means 10B
The ID code S1 is transmitted on a radio wave (step 102 in FIG. 3).

The ID code S1 is radiated into the air via the antenna 10C and received by the ID code receiving means 11B of the control circuit 11 incorporated in the key storage device 13 (FIG. 2) via the antenna 11A. Is done.

That is, the ID code transmitting means 10B modulates an ID code S1 of a predetermined frequency on a carrier of a radio wave and transmits the modulated signal.

However, as means for transmitting the ID code S1, in addition to this radio wave, optical communication using infrared light or visible light, communication using air vibration of a specific frequency such as a dial tone or an acoustic coupler signal, or the like may be used. It is possible.

The alarm start / stop signal receiving means 10D extracts an alarm start signal S2 or an alarm stop signal S3 (FIG. 2), which will be described later, sent from the key storage device 13 from the carrier wave and demodulates them.

As a result, the alarm start / stop signal receiving means 10D controls the alarm means 10E (FIG. 2) at the subsequent stage to start or stop the alarm AL (step 104 in FIG. 3) or stop (step 106 in FIG. 3). .

The alarm means 10E issues an alarm AL by outputting an alarm sound such as a voice or a melody via the speaker 8 (FIG. 1), for example.

However, the alarm means 10E generates an alarm AL other than the above-mentioned alarm sound by vibrating the remote control device 12 or emitting a flash light.
It is also possible to call attention that is open.

The alarm means 10E (FIG. 2) can be installed not only in the remote control device 12, but also in the key storage device 13.

Thus, for example, even when the user is operating the remote control device 12 in his pocket, the user operating the remote control device 12 can be further alerted.

That is, the alarm sound may be difficult to hear when it is emitted from the remote control device 12 which is shielded from the outside while being kept in the pocket.

However, if the alarm means 10E is also installed in the key storage device 13 which is generally exposed to the outside, the alarm sound emitted therefrom becomes very easy to hear.

By installing the alarm means 10E in both the remote control device 12 and the key storage device 13 as described above, if the alarm sound does not stop forever, the lid 2 can be opened even to a person indoors. And the effect of preventing the lid 2 from being left open is increased.

Further, when the alarm means is provided only in the key storage device 13, the alarm means 10E on the remote control device 12 side.
(FIG. 2) and the alarm start / stop signal receiving means 10D can be omitted, and the remote control device 12 can be reduced in size.

A reception start switch 11F can be connected to the ID code receiving means 11B (FIG. 2).

By activating the control circuit 11 (FIG. 2) of the key storage device 13 only when the ID code S1 is received, unnecessary power consumption due to constant reception can be suppressed. The life of the battery serving as the power supply of the key storage device 13 can be extended.

The ID code collating means 11C comprises: an ID code S1 transmitted from the ID code receiving means 11B;
The ID code registered with itself is compared and collated, and the collation result is transmitted to the lid locking means 11D of the next stage.

The lid lock means 11D is connected to and controls the lid opening / closing mechanism 3 (FIG. 1).

In other words, the lid lock means 11D operates when the collation result by the ID code collation means 11C is normal, in other words, when the ID code S1 sent from the remote controller 12 matches the registered one. (Step 202 in FIG. 3), the lid opening / closing mechanism 3 is operated to unlock the lid 2 (Step 203 in FIG. 3).

Thus, the person who operates remote controller 12 can open key 2 (FIG. 1) and remove key 4 from box 1.

When the lid lock means 11D detects that the lid 2 has been closed via the microswitch 3A constituting the lid opening / closing mechanism 3 (FIG. 1) (YES in step 205 in FIG. 3). The lid opening / closing mechanism 3 is operated to lock the lid 2 (Step 206 in FIG. 3).

When the lid lock means 11D unlocks the lid 2 (step 203 in FIG. 3), the alarm start / stop signal transmitting means 11E transmits the alarm start signal S2 on a radio wave (FIG. 3). In step 204), or when the lid lock means 11D locks the lid 2 (step 206 in FIG. 3), an alarm stop signal S3 is transmitted over radio waves (step 207 in FIG. 3).

That is, the alarm start / stop signal transmitting means 11E
Transmits an alarm start signal S2 or an alarm stop signal S3 of a predetermined frequency on a carrier of a radio wave, modulating the signal.

However, in addition to radio waves, optical communication using infrared light or visible light, communication using air vibration of a specific frequency such as a dial tone or an acoustic coupler signal, or the like can be used as the transmission means.

The alarm start signal S2 or the alarm stop signal S3 (FIG. 2) is radiated into the air via the antenna 11A, and constitutes the alarm start / stop constituting the control circuit 10 (FIG. 2) of the remote controller 12. The signal is received by the signal receiving means 10D (FIG. 2) via the antenna 10C.
