Claim 14:
15. A locking/unlocking device comprising:
a drive unit, including at least one of an actuator and a motor, configured to drive a lock mechanism of an opening/closing device;
a magnetic detection sensor configured to detect a change in a magnetic field based on a change in a relative position between a movable section and a fixed section of the opening/closing device;
control circuitry configured to determine an open/closed state of the opening/closing device on the basis of the change in the magnetic field detected by the magnetic detection sensor, and to activate the drive unit to lock or unlock the lock mechanism on the basis of the open/closed state; and
a lock/unlock detection sensor configured to detect a locked/unlocked state of the lock mechanism of the opening/closing device, wherein
the control circuitry is further configured to perform an automatic lock control, and the lock/unlock detection sensor is further configured to deactivate the automatic lock control under a condition it is determined that the lock mechanism is in the unlocked state multiple times within a predetermined period of time.
