  As disclosed in Patent Document 2, it is convenient to accommodate the portable device and the mechanical key in one case, but forgetting to store the mechanical key in the case, it may be difficult to deal with an emergency. There is.

  The present invention has been made in view of such circumstances, and the portable device and the mechanical key can be combined in a compact manner to improve portability, and the mechanical key can be forgotten to be accommodated in the case. An object is to provide a key unit that is not provided.

In order to achieve the above object, the present invention constitutes a part of a portable device together with a case that can be opened and closed and a wireless signal that switches between a locked state and an unlocked state of a door lock mechanism. In this way, it is possible to switch between the transmitting unit housed in the case and the locked state and unlocked state of the door lock mechanism according to mechanical operation, and at least a part of the door unit is inserted into and removed from the case. In a key unit composed of a mechanical key that can be accommodated, it is possible to contact the mechanical key in the case, and at least a part of the mechanical key is accommodated in the case and is not accommodated A moving member supported to be displaceable by the case so as to change its position in a state, and switching by the displacement of the moving member The portable device is configured such that the detecting means including a switch arranged in the transmission unit so as to change the mode allows the operation of the transmission unit only in a state where the housing state of the mechanical key is detected. A detection resilient member that exerts a resilient force that is provided in a machine and that biases the mechanical key accommodated in the case toward the side that abuts the moving member, the movable member sandwiching the mechanical key The first feature is that it is attached to the inner surface of the case in such a manner as to face.

  According to the present invention, in addition to the configuration of the first feature, at least a part of the case includes first and second case members that are formed in a dish-like shape with their opposite sides open and are detachably coupled. The transmission unit accommodated in the unit case is accommodated and fixed in the first case member, and the second case member is elastically contacted with the mechanical key to press the mechanical key against the unit case. The flapping member for suppressing flapping for suppressing flapping is accommodated, and the second member for detecting detection is attached so that the flapping member for flapping suppression is sandwiched between the second case member. It is characterized by.

According to the first feature of the present invention, the case of the portable device is configured to be openable and closable, and at least a part of the mechanical key is accommodated in the case. Even if there is a problem with keyless entry with a portable device, you can easily take out the mechanical key that you are carrying, but you can easily take out the mechanical key by opening the case The door lock mechanism can be switched between a locked state and an unlocked state by a mechanical operation according to, and there is no problem in an emergency. Also, if the detecting means does not detect the housing state of the mechanical key in the case, the transmission unit cannot be operated, so do not forget to house the mechanical key in the case, and be sure to deal with it in an emergency. Can do. In addition, the detection means includes a moving member supported so as to be displaceable by the case so as to be able to abut on the mechanical key, and a switch for changing a switching mode by the displacement of the moving member, and abuts the mechanical key on the moving member. The detection resilient member that exerts the resilient force that is biased toward the moving side is attached to the inner surface of the case so as to face the moving member with the mechanical key interposed therebetween. The accommodation state of the mechanical key in the case can be reliably detected.

  Further, according to the second feature of the present invention, the flapping member for flapping suppression can suppress flapping of the mechanical key in the case by pressing the mechanical key against the unit case, and the flapping member for detection. Since the flapping member for suppressing fluttering is attached to the second case member so as to be sandwiched between the second case member, the first member that is separably coupled without the need for attaching only the flapping member for flapping suppression is unnecessary. And, when the second case member is opened for battery replacement or the like, it is possible to prevent the flapping member for suppressing flapping from falling off the second case member.

The transmission unit (23) accommodated in 24) is accommodated and fixed in the first case member (14), and the second case member (15) is elastically contacted with the mechanical key (11) to A flapping member (54) for suppressing flapping for suppressing flapping is accommodated by pressing the mechanical key (11) against the unit case (24), and the flapping member (54) for flapping suppression is used as the second case. 2. The key unit according to claim 1, wherein the detection elastic member (68) is attached so as to be sandwiched between the member (15).
