The invention claimed is:

1. An elevator device comprising:
an evacuation operation mode requesting device provided at a hall of an elevator on a rescue floor and configured to be operated;
a car operation instructing device provided at the hall of the elevator on the rescue floor and configured to be operated; and

set an operation mode of the elevator to an evacuation operation mode in which a car of the elevator travels between a rescue floor concerned and an evacuation floor wherein the car moves from the rescue floor concerned to the evacuation floor when the car carries an evacuee when the evacuation operation mode requesting device is maintained in an operated state;
maintain the evacuation operation mode corresponding to the rescue floor concerned based on the car operation instructing device being operated on the rescue floor concerned before a predetermined time passes from when the car stops at the rescue floor concerned during an evacuation operation mode corresponding to the rescue floor concerned; and
release the evacuation operation mode corresponding to the rescue floor concerned when the car operation instructing device is not operated on the rescue floor concerned before the predetermined time passes from when the car stops at the rescue floor concerned during the evacuation operation mode corresponding to the rescue floor concerned.

2. The elevator device according to claim 1 , wherein, when the car operation instructing device is not operated on the rescue floor concerned before the predetermined time passes from when the car stops at the rescue floor concerned during the evacuation operation mode corresponding to the rescue floor concerned, the control device closes doors of the elevator after releasing the evacuation operation mode corresponding to the rescue floor concerned and moves the car to the evacuation floor.

3. The elevator device according to claim 1 , further comprising a notification device provided at the hall of the elevator on the rescue floor and configured to notify that the evacuation operation mode corresponding to the rescue floor concerned is scheduled to be released before the doors of the elevator are closed after the evacuation operation mode corresponding to the rescue floor concerned is released because the car operation instructing device is not operated on the rescue floor concerned before the predetermined time passes from when the car stops at the rescue floor concerned during the evacuation operation mode corresponding to the rescue floor concerned.

4. The elevator device according to claim 3 , wherein, when the car operation instructing device is operated on the rescue floor concerned before the doors of the elevator are fully closed after it is notified by the notification device that the evacuation operation mode corresponding to the rescue floor concerned is scheduled to be released, the control device cancels the schedule of release of the evacuation operation mode corresponding to the rescue floor concerned.

5. The elevator device according to claim 1 , further comprising an illumination device provided at the hall of the elevator on the rescue floor concerned and configured to be turned on when the evacuation operation mode requesting device is operated on the rescue floor concerned while the operation mode of the elevator is set to an evacuation operation mode corresponding to another rescue floor, and the control device appoints the evacuation operation mode corresponding to the rescue floor.

6. The elevator device according to claim 5 , further comprising an appointment status indicating device provided at the hall of the elevator on the rescue floor and configured to indicate different information depending on an order at which the operation mode of the elevator is set to the evacuation operation mode corresponding to the rescue floor concerned.
