      2. Description of the Related Art Generally, elevator devices are installed in various types of high-rise buildings constructed by residential and commercial roads for smooth movement of passengers looking for buildings in the vertical direction.

      Recently, a double deck elevator car, which is composed of two upper and lower elevator cars so as to increase the transportation capacity in a single hoistway, can be provided so that two floors of the building can be simultaneously serviced.

      FIG. 1 is a schematic view of a general chain-driven double deck elevator. In the chain-driven double deck elevator, when the deck controller 5 rotates the motor in the normal direction, the upper deck 20 moves upward, The deck 30 is moved in the downward direction, so that the decks are spaced apart from each other.

      Further, when the motor of the deck controller 5 is rotated in the opposite direction, the upper deck 20 moves downward and the lower deck 30 moves upward, so that the interval between the decks is narrowed.

      At this time, in the case of the double-deck elevator having the above-described structure, a change in the elasticity of the main rope 3 and the deck chain 7 due to the load fluctuation due to the loading / unloading of the passengers of the upper deck 20 and the lower deck 30 And congestion errors of the upper deck 20 and the lower deck 30 are generated due to such changes in the elasticity of the main rope 3 and the deck chain 7. Such a conception error is caused, Such as when a passenger lifts the elevator or when a passenger inside the elevator gets off the car, it takes a dangerous situation such as a foot on the platform.

      Therefore, in the conventional double deck elevator, in order to correct the embedding error caused by the change of the elasticity of the main rope 3 and the deck chain 7, the upper deck 20 and the lower deck 30 are fixed A frame, that is, a main deck 10 frame is moved in an upward or downward direction to correct the implantation level.

      However, in the conventional method of correcting the error of the implantation level as described above, the upper deck 20 has no error in the implantation level and only the lower deck 30 has an error in the implantation level, The upper deck 20 and the lower deck 30 can not correct the conception error in a situation where an error is generated only in the upper deck 20 and the lower deck 30, 30, even if there is a difference in the conception level error between the upper level deck 20 and the lower level deck 30, correction errors can not be corrected correctly.
