The case 17 accommodates the drive device 12, the conversion circuit 13, and the pairing switch 14. A thumb turn 15 is provided on the upper surface of the case 17. On the outdoor side surface of the door 8, a key cylinder 16 is provided on the opposite side of the thumb turn 15 across the door 8. The thumb turn 15, the drive device 12, the lock mechanism 10, and the key cylinder 16 are connected by a rotating shaft 19 via a gear or the like. The case 17 is attached to the door 8 by a mounting plate 18.

  The lock mechanism 10 is provided with a dead bolt 11 as a lock so as to protrude into a recess (not shown) provided in a wall portion facing the door 8 of the building. The drive device 12 is provided with a motor (not shown), and the rotation shaft 19 is rotated by driving the motor. The dead bolt 11 protrudes into the recess or is accommodated in the lock mechanism 10. When the dead bolt 11 is projected, the door 8 is locked by engaging the dead bolt 11 and the recess.

The conversion circuit 13 is connected to the control device 2, the motor 12 a of the drive device 12, and the pairing switch 14. The conversion circuit 13 includes a memory 13 a that stores an authentication code as authentication information used when performing connection authentication with the control device 2.

  When the pairing switch 14 is pressed, an ON signal is output to the conversion circuit 13, and the conversion circuit 13 authenticates the connection to the control device 2. That is, the conversion circuit 13 outputs an authentication signal for outputting the authentication code to the control device 2. When the authentication signal is input, the control device 2 reads the authentication code from the memory 2 a and outputs a response signal including the authentication code to the conversion circuit 13. When the response signal is input, the conversion circuit 13 reads the authentication code from the response signal and stores it in the memory 13a. In this way, the connection authentication between the control device 2 and the conversion circuit 13 is performed, whereby the control device 2 and the conversion circuit 13 are associated one-to-one, and between the control device 2 and the conversion circuit 13. Communication becomes possible.

  The control device 2 intermittently outputs transmission signals to the indoor antenna 3 and the outdoor antenna 4 so as to output request signals for forming the predetermined areas A1 and A2 indoors and outdoors of the door 8. When the portable device 20 receives the request signal, the portable device 20 transmits an ID code signal including an ID code. The indoor antenna 3 and the outdoor antenna 4 output the received signal to the control device 2 when the ID code signal is received. When the received signal is input, the control device 2 collates the ID code included in the received signal with the ID code read from the memory 2a. If they match, the control device 2 reads the authentication code from the memory 2a. The lock signal is output to the conversion circuit 13. When the unlocking signal is input, the conversion circuit 13 collates the authentication code included in the unlocking signal with the authentication code read from the memory 13a, and applies a drive voltage to the motor 12a if they match. And the dead bolt 11 is accommodated in the lock mechanism 10 by the drive of the motor 12a, and the door 8 is unlocked.

  On the other hand, when the reception signal is not received, the control device 2 reads the authentication code from the memory 2 a and outputs a lock signal including the authentication code to the conversion circuit 13. When the lock signal is input, the conversion circuit 13 collates the authentication code included in the lock signal with the authentication code read from the memory 13a, and applies a drive voltage to the motor 12a if they match. And the dead bolt 11 protrudes from the lock mechanism 10 by the drive of the motor 12a, and the door 8 is locked.

  When an operation button (not shown) for locking or unlocking is operated, the operation panel 7 outputs an operation signal to that effect to the control device 2. The control device 2 outputs a lock signal or an unlock signal to the conversion circuit 13 in accordance with the lock or unlock of the operation signal. The conversion circuit 13 collates the authentication code included in the locking signal or the unlocking signal with the authentication code read from the memory 13a, and locks or unlocks the door 8 if they match. The control device 2 detects the state of the electric lock 1 on the basis of the detection signal from the detection sensor 35 as detection means for detecting locking and unlocking provided in the drive device 12, and locks or unlocks the operation panel 7. Output a signal. The operation panel 7 displays a locked or unlocked state based on the state signal.

As described above, according to the embodiment described above, the following effects can be obtained.
(1) Since the control device 2 and the conversion circuit 13 of the electric lock 1 are connected by the communication wiring Wb, an intruder trying to enter the building applies a voltage to the communication wiring Wb by some method. However, since the drive device 12 cannot be driven, crime prevention can be enhanced. In addition, since the power supply wiring Wa is connected to the drive device 12 from the conversion circuit 13 provided in the vicinity of the drive device, the power supply is performed even when the wiring Wa is short, for example, when the door 8 is perforated from the outside. It is difficult to pull out the work wiring Wa to the outside, and it is difficult for an intruder to apply a voltage to the wiring Wa.

  Moreover, if the communication system between the control device 2 and the conversion circuit 13 of the electric lock 1 in the industry is unified, it can be a general-purpose electric lock, and the manufacturer only has the control device or only the electric lock. Development and manufacturing can be performed, and it is not necessary to develop and manufacture the entire system, so that development cost and manufacturing cost can be reduced. For example, when a system is constructed, a manufacturer develops only a control device having a unique operation specification, and an electric lock can be used from another manufacturer with versatility. A manufacturer can also provide only a versatile electric lock.

  (2) The electric lock 1 performs connection authentication with the control device 2 when the pairing switch 14 is operated, and verifies the authentication code when a signal is input from the control device 2. Thus, even if the intruder outputs an unlock signal indicating that the deadbolt 11 is unlocked to the communication wiring Wb, the authentication code does not match and therefore the unlocking is not unlocked. As a result, crime prevention can be further enhanced.

(3) The control device 2 can grasp the locking and unlocking state of the electric lock 1 through the detection sensor 35 provided in the electric lock 1.
In addition, the said embodiment can be implemented with the following forms which changed this suitably.
