However, in such a conventional elevator control device, when the user in the car gets out of the car, no one operates the door close command switch in the car, and the elevator Wait at the stop floor with the door open until a predetermined time has passed, then
There is a problem that users who are waiting at the halls on the other floors need to wait unnecessarily for a long time because they will respond to the calls on the halls on the other floors.

[0006] In the case where the passengers who are in the elevator car are stopped one after another at the destination floor, each user who remains in the car operates the door close command switch every time the elevator stops. There is also a problem in that it is necessary to repeatedly perform a troublesome operation for a user who remains in the car until the end.

The present invention has been made in view of such conventional problems, and the elevator operates the door close command switch before the completion of the door opening so that the stop time at the destination floor is normally set. It is an object of the present invention to provide a control device for an elevator which is set shorter than the above and prevents the door from being opened for an unnecessarily long time to improve service.
