The lock body 41 has a cylindrical hub 45 rotatably supported by a housing 44, a dead bolt 46 that advances and retracts in response to the rotation of the hub 45, and a transmission member 47 that operates a push switch described later. Etc. are provided.
A convex portion (driven portion) 45a formed along the cylinder axis direction is provided on the inner peripheral surface of the hub 45.

When the dead bolt 46 is advanced, the dead bolt 46 projects into a strike hole provided in the door frame and locks the door to prevent the door from opening.
In addition, as shown in FIG. 4, the lock body 41 includes an actuator 48 that electrically drives the hub 45, a rack mechanism 49 that drives the dead bolt 46, a push switch 50 that is a switch mechanism that starts the actuator 48, and a receiving antenna. And a printed circuit board 51 on which electronic components constituting the controller are mounted.

The operation lock portion 42 is provided with a cylinder lock 53 protruding rearward from the case 52, and a key insertion hole 54 having a shutter is provided on the surface of the case 52.
Further, an operation button 55 forming a touch switch and a display unit 56 are arranged on the case surface of the operation lock unit 42, and the operation button 55 is integrated inside the operation lock unit 42. There is provided an interlocking member 57 that moves to.

Further, in the present embodiment, a transmitter 58 that outputs a wireless signal to a portable device (not shown) is provided in the operation lock portion 42, and a transmission antenna 59 is provided here, and this transmission is performed. The machine 58 is provided with a connector for electrically connecting to the printed circuit board 51 of the lock body 41.
When the door and the housing 44 of the lock body 41 are made of a material that does not interfere with the passage of wireless signals, the transmitter 58 can be provided on the printed circuit board 51.

As shown in FIG. 4, the operation lock portion 42 is attached to the lock body 41 so that the cylinder lock 53 is partially inserted into the hub 45.
In the operation lock portion 42 thus attached, the engagement plate 53a that rotates integrally with the cylinder inner of the cylinder lock 53 is engaged with the convex portion 45a of the hub 45, and the hub rotates according to the rotation of the cylinder inner by the key. It is designed to rotate 45.

On the other hand, as described above, the push switch 50 is a switch for starting the actuator 48 and electrically locking and unlocking it, and is provided on the printed circuit board 51 as shown in FIG.
The push switch 50 is an automatic double-action push switch, and LEDs 60a and 60b, which emit light in response to a locking/unlocking operation, are provided as light emitting units on a printed circuit board near the push switch. is there.

In the case of the present embodiment, the LEDs 60a and 60b emit light from green to orange when unlocked from the lock, and emit light from orange to green when unlocked from the lock to open the door. Flashes red when the status or error occurs.
Also, when the door is open or an error occurs, a flashing red light is emitted and a buzzer sound is generated.

On the other hand, as shown in FIG. 5, the interlocking member 57 is a tubular member made of a translucent material that is provided so as to be able to advance into the case 52 of the operation lock portion 42.

In the locking/unlocking device configured as described above, the portable device that receives the wireless signal output from the transmitter 58 of the operation lock unit 42 responds, and the wireless signal output by this portable device is received by the receiver of the controller. The controller locks and unlocks the mode by processing the received signal.

For example, when the portable device receives the challenge code signal and the calling code signal output from the transmitter 58 of the operation lock unit 42, the portable device outputs the responding code signal.
The challenge code signal and the calling code signal are, for example, LF (125 kHz) radio signals in consideration of radio interference to peripheral wireless devices, and the response code signal is an RF (315 MHz) radio signal. is there.
Then, when the receiver of the lock body 41 receives the responding cord signal from the portable device, the controller judges whether or not the responding cord signal is proper, and unlocks on the condition that it is proper. Switch to mode.

When the operation button 55 is pressed while the controller is in the unlocking mode, the interlocking member 57 and the transmission member 47 move forward (move to the right in FIG. 5) and push the push switch 50 to perform a switch operation.
Therefore, according to the operation of the push switch 50, the actuator 48 is started to rotationally drive the hub 45.
Note that the hub 45 is provided with a clutch mechanism, and in this case, the drive system by the cylinder lock 53 is cut off.

The rack mechanism 49 gear-connected by the rotation of the hub 45 operates so as to retract the dead bolt 46, whereby the lock of the door is unlocked.
Further, since the LEDs 60a and 60b change to the orange emission color according to the unlocking of the door, the display unit 56 displays orange.
In this embodiment, the door is opened/closed after unlocking, or if the door continues to be opened for a predetermined time, the door automatically double-locks.
If the operation button 55 is released, the operation force of the push switch 50 is returned to the non-operation position shown in FIG.

Although one embodiment has been described above, the transmission member 47 and the interlocking member 57 are not formed of a light-transmissive material, but holes are formed through these, and the light emission of the LED is guided to the display unit 56 through the holes. Can also be
