-Key insertion state-
When the cylinder key is inserted into the keyhole and the operation knob 11 "is not touched, the cylinder lock 20" is released, but as shown by the dotted line in FIG. 11, the tumbler 27 "of the keyhole blocking mechanism 30". Is held across the cylinder lock 20 "and the sleeve 15". As a result, the rotation of the cylinder lock 20 ″ is prevented.
[0091]
In the key insertion detection mechanism 50 ″, the tip of the cylinder key inserted into the key hole 22 ″ pushes the key detection slider 52 ″ from the key hole 22 ″, and the pushed key detection slider 52 ″ slides the link slider 54 ″. Then, the link balance 53 ″ swings. The swinging link balance 53 ″ turns on the key insertion detection switch 34 ″ and also has a locking projection provided with a locking projection 55 ″ on the sleeve 15 ″. Engage with 15e ″ to lock the rotation of sleeve 15 ″.
[0092]
Since the knob operation detection mechanism 40 ″ is in a state where the knob operation detection slider 42 ″ is urged by the operation detection slider sliding surface 14 ″ by the knob operation detection switch 41 ″, the knob operation detection switch 41 ″ is in the off state. It is.
[0093]
In the cylinder rotation detection mechanism 60 ″, since the operation knob 11 ″ is not rotated, the rotation detection slider 63 ″ remains biased by the cam portion 61 ″. Is off.
[0094]
From the above, when the cylinder key is inserted into the keyhole 22 "and the operation knob 11" is not touched, the key insertion detection switch 34 "is turned on, the knob operation detection switch 41" and the cylinder rotation detection switch 64. Since ″ is off, a key insertion detection signal is input to the control unit.
[0095]
-Key insertion knob pressed-
When the operation knob 11 "is pressed in the axial direction from the state in which the cylinder key is inserted into the key hole 22", the key hole blocking mechanism 30 "has the sleeve 15" and the cylinder lock 20 as shown in FIG. The tumbler 27 "straddling" is moved into the tumbler insertion hole 26 "provided in the cylinder lock 20", and the engagement between the sleeve 15 "and the cylinder lock 20" by the tumbler 27 "is released. A hole 27b "provided in the tumbler 27" slides and engages with a locking portion provided in the cylinder key 21 ". As a result, the cylinder key cannot be pulled out from the key hole 22 ", and the cylinder lock 20" can be rotated with respect to the sleeve 15 ", and the lock member 80" can be operated.
[0096]
As shown in FIG. 15, the knob operation detection mechanism 40 ″ slides the operation detection slider sliding surface 14 ″ by the knob operation detection slider 42 ″ and turns on the knob operation detection switch 41 ″.
[0097]
From the above, when the cylinder key is inserted into the keyhole 22 ″ and the operation knob 11 ″ is pressed in the axial direction, the key insertion detection switch 34 ″ and the knob operation detection switch 41 ″ are turned on, and the cylinder rotation detection switch 64 ″ Is off, the key insertion detection signal and the operation detection signal are input to the control unit. As a result, the control unit preferentially shifts to the auxiliary lock operation mode, and the electronic key and the operation unit ID match. However, priority is given to the auxiliary lock operation mode rather than the electronic key operation mode.
[0098]
Further, when the operation knob 11 ″ is rotated from this state, the cam portion 61 ″ of the cylinder lock 20 ″ is rotated and the rotation detection slider 63 ″ is slid to turn on the cylinder rotation detection switch 64 ″.
[0099]
Accordingly, when the cylinder key is inserted into the keyhole and rotated while pressing the operation knob 11 ″ in the axial direction, the key insertion detection switch 34 ″, the knob operation detection switch 41 ″, and the cylinder rotation detection switch 64 ″ are all turned on. Since the state is reached, a key insertion detection signal, a knob operation detection signal, and a cylinder rotation detection signal are transmitted to the control unit.
[0100]
With the above configuration, since the cylinder key 21 "cannot be inserted while the operation knob 11" is being operated, it is possible to prevent the lock device 1 "from malfunctioning.
[0101]
In addition, since the key insertion detection switch 34 ″ is provided, the control unit can identify whether or not the cylinder key 21 ″ is inserted into the key hole 22 ″, so that it is possible to switch between the electronic key operation mode and the auxiliary lock operation mode. Can be done more reliably.
[0102]
In this embodiment, the key insertion detection switch 34 ″ biases the key stopper 32 ″ against the inner wall of the key hole 22 ″. However, biasing means such as a spring is used instead of the key insertion detection switch 34 ″. However, it is possible to prevent the cylinder key 21 ″ from being inserted while the operation knob 11 ″ is being operated.
[0103]
Further, in this embodiment, the cylinder lock 20 ″ is used as the auxiliary lock, but the same effect can be obtained even if the lock of the immobilizer system is used.
[0104]
