PICTURE BOOK
An escalator in which steps come out one after another from under the floor. Many people are carried to the upper and lower floors one after another. On the other hand, elevators are limited in number of people, but they carry people to distant floors at once. An escalator that moves while enjoying a leisurely view of each floor, and an elevator that moves quickly. Both are familiar vehicles that are often installed in places where many people gather. How do they work? The tips for getting on and off well are also introduced.
