Abstract (en)
There is provided an elevator hatch door apparatus capable of preventing a locking device for a hatch door surely and easily from being unlocked by a person other than an authorized person. For this purpose, the elevator hatch door apparatus comprises a locking device for locking an elevator hatch door; an unlocking device for unlocking the locking device; an authentication device for authenticating an authorized person who is authorized to unlock the locking device; and an unlocking limiter for enabling the unlocking operation of the unlocking device based on the authentication result of the authentication device. In the case where it is confirmed by the authentication device that the authenticated person is the authorized person registered in advance, the unlocking operation limitation of the unlocking device imposed by the unlocking limiter is removed. In the case where it is not confirmed by the authentication device that the authenticated person is the authorized person, the unlocking operation limitation of the unlocking device imposed by the unlocking limiter is maintained.
