By the way, a smart key system (registered trademark) mounted on a vehicle is known.
The smart key system is a system for remotely controlling an in-vehicle device as an external device mounted on a vehicle by wireless communication using a smart key which is a portable device, and permitting or prohibiting a predetermined operation by the in-vehicle device. .. Examples of the predetermined operation include a door unlocking operation in a vehicle, a vehicle starting operation (engine starting operation), and the like.

A key case for accommodating a smart key used in a smart key system can be considered. In this type of key case, it is considered that the radio waves transmitted by the smart key can be transmitted to the outside without removing the smart key from the key case, and the convenience of the user can be improved by making the in-vehicle device remotely controllable. ..

Further, in a vehicle equipped with a smart key system, there is a possibility that theft damage may occur by using a technique called relay attack using a relay device that relays wireless communication.
The relay attack creates a state in which wireless communication between the on-board unit and the smart key is possible by using multiple relay devices that relay wireless communication even when the smart key is placed inside the house. It is a theft method that steals a vehicle by enabling the door unlocking operation and the vehicle starting operation. By using the relay device in this way, even if the distance between the on-board unit and the smart key exceeds the permitted range, the vehicle door can be unlocked, the vehicle can be started, and the vehicle can be stolen. .. Therefore, with respect to the key case that houses the smart key, it is desirable that such a relay attack can be suppressed while the smart key is housed in the key case.

In addition, not only smart keys, but also small items that can communicate with external devices such as in-vehicle devices, and general small items accommodating devices that accommodate such small items, can be referred to as external devices without removing the small items from the small items accommodating device. There is a need to allow the communication of the above and to suppress the wrongdoing by using the radio wave used for the communication.

Then, the edge portion (that is, the side wall portion 523b) of the recessed portion 523c protrudes from the first contact portion 521 and the second contact portion 522 in the separation direction B.

Therefore, since the two contact portions 521 and 522 are installed inside the recessed portion 523c, it is difficult for the user to touch the two contact portions 521 and 522 unless the user intentionally touches the two contact portions 521 and 522. Therefore, as compared to the case where the two contact portions 521 and 522 are simply installed on a flat surface rather than inside the recessed portion 523c, the user mistakenly contacts the two contact portions 521 and 522, and the user intends to do so. It is possible to prevent the radio wave from the smart key 2 from being transmitted to the outside of the key case 5.

In the present embodiment, the key case 5 corresponds to the accessory accommodating device, the internal antenna 12 and the external antenna 51 correspond to the transmitting / receiving unit, the internal antenna 12 corresponds to the receiving unit, and the external antenna 51 corresponds to the transmitting unit. However, the contact portions 521 and 522 correspond to specific parts in the accessory container.

In the key case 6 of the present embodiment, as described above, the first fastener 64 is conducted with the internal antenna 62. Further, in the closed state, the first fastener 64 and the second fastener 65, both of which are conductors, come into contact with each other and become conductive. As a result, the internal antenna 62, the first fastener 64, and the second fastener 65 become conductive in the closed state. Then, as in the first embodiment, when the user's finger comes into contact with the second fastener 65 exposed to the outside of the key case 6 in the closed state, the user functions as an antenna. In other words, the user is located outside the key case 6 and functions as an antenna for transmitting radio waves from the smart key in the housing unit 611 to the outside and / or receiving radio waves from the vehicle-mounted device.

(4b) In the present embodiment, the fastener 63 for keeping the opening / closing portion 612 in the closed state plays a role as a component for conducting the inside and the outside of the key case 6. That is, one part has two functions, that is, a function as a fastener and a function as a conductive part. Therefore, it is not necessary to provide a conductive component separately from the fastener 63. Therefore, the manufacturing cost of the key case 6 can be reduced and the appearance of the key case 6 can be simplified as compared with the configuration in which the parts for conducting the conduction are provided separately from the fastener 63.

(4c) In the present embodiment, the first fastener 64 includes a convex portion 64b, and the second fastener 65 includes a concave portion 65b. Then, the first fastener 64 and the second fastener 65 are fastened by fitting the convex portion 64b and the concave portion 65b.

Therefore, the first fastener 64 and the second fastener 65 are firmly fastened. As a result, the first fastener 64, the second fastener 65, and the internal antenna 62 can be satisfactorily conducted in the closed state. As a result, a good communication state between the vehicle-mounted device and the smart key can be realized in a state where the user is in contact with the second fastener 65.

In the present embodiment, the key case 6 corresponds to the accessory container.
