Abstract
In an elevator door apparatus, an elevator door is capable of reciprocating between a door closure position for closing an elevator entrance and a door open position for opening the elevator entrance. The elevator door is driven by a door drive device. The door drive device is controlled by a door control device. The door control device adjusts the door open position based on control information for controlling an operation of an elevator, obtains a door opening/closing pattern for the elevator door to be opened and closed between the adjusted door open position and the door closure position, and controls the door drive device so that the elevator door is reciprocated in accordance with the obtained door opening/closing pattern.
