Is integrally stored in the mounting case 16 on which the mobile phone 21 is mounted. The mounting case 16 is installed in a place away from the entrance door 30, for example, in a living room or the like, and the unlocking control unit 14 and the lock driving unit 15 are connected by a signal line 17. However, the connection may be made wirelessly.

FIG. 2 is an external view of the mounting case 16. The carrying case 16 has a mobile phone holder 16a for holding the mobile phone 21 in an upper surface thereof.
The mobile phone 21 can be attached to and detached from the mounting case 16 by sliding the mobile phone 21 in the arrow X direction.

In the present embodiment, the unlocking system having such a configuration is provided separately from the lock 31 of the conventional entrance door 30. That is, this unlocking system is used as a supplement to the conventional lock 31.

Therefore, the user who goes out has the entrance door 30.
The lock 31 is locked with a key as before, and the lock device 12 of the present embodiment is also locked and goes out.

Various structures can be adopted as the lock structure of the lock control device 12. For example, it can be configured to be automatically locked by closing the front door 30 while pressing a button (not shown) provided on the locking device 12. Such a structure is automatically locked by, for example, providing a lock mechanism section by a push button method on the indoor side of a cylindrical door knob and tightening the door while pushing this lock mechanism section when going out. The same structure as that of the conventional locking device can be adopted.

After locking in this way, when the user returns from the place where he / she is going, he first uses the key to lock 31
Unlock, and then from another mobile phone, place case 1
Make a call to the mobile phone 21 mounted on the mobile phone 6. The mobile phone 21 that has received this outgoing signal executes an incoming operation of ringing a bell. The electromagnetic wave generated when the mobile phone 21 receives a call is detected by the electromagnetic wave detection unit 1 in the device case 16.
3 is detected, the unlock control unit 14 receives this detection signal.
Outputs a drive control signal to the lock driving unit 15 to unlock the lock device 11. Accordingly, the user can enter the building by opening the entrance door 30 while the lock device 11 is performing the unlocking operation.

In the above embodiment, the electromagnetic wave detecting section 1
Outputs a detection signal only when 3 is detecting an electromagnetic wave,
The unlocking control unit 14 may output the drive control signal to the lock driving unit 15 to unlock the lock device 11 only when receiving the detection signal. That is, the locking device 11 is unlocked only when the mobile phone 21 is ringing. With such a configuration, the entrance door 3 can be operated only when the mobile phone 21 is ringing.
Since 0 cannot be opened, some effect can be expected in terms of security.

On the other hand, apart from such a configuration, the electromagnetic wave detection unit 13 detects an electromagnetic wave and once outputs a detection signal to the unlocking control unit 14, the unlocking control unit 14 determines, based on this detection signal, A configuration may be adopted in which a drive control signal is output to the lock driving unit 15 to unlock the lock device 11.
That is, once the detection signal is received, the lock device 11 remains unlocked even after the mobile phone 21 finishes the incoming operation.

In order to use the mobile phone 21 as a part of such an unlocking system, it is natural that only the family member needs to know the phone number of the mobile phone 21.

Further, in the above embodiment, the unlocking system of the present invention is used as an aid to the conventional lock. Therefore, little consideration is given to the security of the unlocking system itself. Therefore, when the unlocking system of the present invention is used in place of the conventional lock, it is necessary to strengthen security.

As one of such security enhancements, the number of times electromagnetic waves are detected by the electromagnetic wave detection unit 13 is measured, and the lock device 11 is unlocked only when the number of times of detection exceeds a certain number (for example, 10 times). The system can be built.

As another security enhancement, the mobile phone 21 may be configured to perform an incoming call operation only when an incoming call is received from a specific number. In other words, if the setting is made so that the incoming operation is performed only when the mobile phone of the family has an incoming call, even if the phone number accidentally called by another person is the phone number of the mobile phone 21,
Since the mobile phone 21 does not perform the incoming operation, security is strengthened in that sense.

In the above embodiment, the entrance door is taken as an example of the object requiring the key, but the unlocking system of the present invention is not limited to such a door relationship. , Applicable to anything that requires a key. For example, the unlocking system of the present invention can be applied to an attache case used by a businessman, a duralumin case used for cash transportation, and the like.

For example, when applied to the attache case 40, as shown in FIG. 3, the lock device 11 and the lock drive unit 12 shown in FIG. 1 are housed on the back side of one side 41a of the case body 41. The lock case 15 and the mounting case 16 accommodating the unlock control unit 13 and the electromagnetic wave detection unit 14 may be integrally attached and fixed. And
The key portion 45 conventionally attached to the front edge portion 43a of the lid 43 of the attache case 40 is locked to the key receiving portion 46 conventionally attached to the front surface side of the one side 41a of the case body 41. When the lid 43 is closed,
The lock device 11 may be configured to lock the key receiving portion 46 inside so that the key portion 45 is not unlocked even if the key receiving portion 46 is operated from the outside. However, such a configuration is an example, and how the unlocking system of the present invention is combined with an existing key or whether it is provided completely independently can be arbitrarily changed in design.

In each of the above embodiments, the mobile phone 21 is illustrated as an example of the mobile communication terminal, but the same applies even if a pager is used.

Further, in each of the above-mentioned embodiments, as the object requiring the key, a door such as a front door and a storage case such as an attache case have been described as an example. It goes without saying that the unlocking system of the present invention can be applied to any object that requires the.
