TECHNICAL FIELD The present invention relates to an elevator,
In particular, the present invention relates to an elevator having a function of rotating a car in an elevator shaft.

[0002]

2. Description of the Related Art Elevators have become indispensable facilities for daily life with the rise of urban skyscrapers. For elevators for high-rise buildings, various types of elevators that can operate at high speed and have a comfortable ride are available. The system is being developed. Further, in recent years, small-sized elevators have been tending to be installed in low-level general dwellings and station platforms in order to make barrier-free in view of an aging society. In the case of elevators for high-rise buildings, it is common to use a "rope type" in which the basket is suspended with a rope and the rope is wound up with a motor.
In a small-scale elevator, a “screw type” using a drive shaft having a screw screw formed on a surface is also used.

[0003]

Usually, the entrance to the elevator car is set in the same direction for all floors. For example, if the entrance on the first floor of an elevator is located on the south side of the elevator,
Even on the second floor and above, the entrance will always be located on the south side. Generally, in the case of an elevator for a high-rise building, even if the entrances of each floor always face the same direction, there is little inconvenience. Rather, in order to standardize the floor plan of each floor, it is preferable that the entrance of each floor always faces the same direction. However, in the case of a small elevator installed in a low-level general residence or a platform of a station, if the direction of the entrance can be changed for each floor, the degree of freedom of design increases, which is preferable. . For example, in the case of an elevator installed at a station, we would like to place the entrance on the first floor facing south, facing the street, but arrange the entrance on the second floor east, considering the direction of the platform. There are quite a few circumstances. However, conventional elevators are basically designed on the premise that the entrances on each floor always face the same direction, and it is difficult to perform a flexible design in consideration of such circumstances. There has been proposed a method in which a plurality of doors are provided in a basket so that the user can get on and off from different directions for each floor.However, providing a plurality of doors in a basket increases the cost, This is also undesirable because it can cause confusion for passengers.

Accordingly, an object of the present invention is to provide an elevator capable of arbitrarily setting the direction of an entrance / exit for each floor.
