Abstract
An elevator information device is disclosed. The elevator information device has displays located in each hall of a building, each of which can display the service state of the elevator (information on arrival of a car, number of passengers in the car, floors at which the car is about to stop, waiting time, position of the car) by means of pictures and characters, whereby waiting passengers can easily understand the condition of the elevator. As a result, the waiting passengers do not feed uncomfortable due to confusion, impatience or distrustfulness. Consequently, the waiting passengers can be guided smoothly.
