Abstract: Provided is a locking/unlocking device that accurately detects an opening/closing state of an opening/closing device and optimizes timing to lock or unlock.
The locking/unlocking device includes a drive unit that drives a lock mechanism of the opening/closing device, a magnetic detection unit that detects a change in a magnetic field based on a change in the relative position between a movable section and a fixed section of the opening/closing device, and a control unit that determines an open/closed state of the opening/closing device on the basis of the change in the magnetic field detected by the magnetic detection unit and activates the drive unit to lock or unlock the lock mechanism on the basis of the open/closed state.
