SAFETY DOOR DEVICE AND SAFETY DOOR LOCKING METHOD
A safety door device according to an aspect includes: a full closing detector for detecting that a safety door has fully closed from an opened state; a locking mechanism for locking the safety door so that the safety door does not open; a measurement unit (acceleration sensor, control unit for measuring a travel acceleration, a travel speed, or a travel time when the safety door closes; and a control unit for controlling the locking mechanism to lock the safety door when the safety door is detected to be fully closed. If the travel acceleration or the travel speed is greater than a first threshold, or if the travel time is shorter than a second threshold, then the control unit does not cause the safety door to be locked.
