Description of the Related Art Conventionally, in a multi-storey parking lot, a parking area in a receiving room and a parking area in a parking rack are formed to have the same size, and a vehicle length and a vehicle width of a vehicle entering the receiving room are detected by a size limiting detector. By determining whether or not the vehicle fits in the parking area of the storage room, it is simultaneously determined whether or not the vehicle fits in the parking area of the parking shelf. In addition, even if the vehicle is a standard vehicle that fits in the parking area, if you park it diagonally, a part of the vehicle will protrude to the outside of the parking area and you will be mistakenly determined to be a nonstandard vehicle. The principle was to park at.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described conventional configuration, if the parking area in the storage room is set to be large so that the vehicle can be stored in the parking area even if the vehicle is parked at an angle, a parking shelf for storing the vehicle Also, it is necessary to set a large parking area in the elevator that conveys the vehicle to each floor, and there is a problem that the entire device of the multi-story parking lot becomes large and the number of vehicles that can be accommodated in the predetermined site decreases. Further, if the parking area in the storage room is made small, it is difficult for an unfamiliar driver to park in the parking area in the storage room.

The present invention solves the above problem, and by correcting the posture of a vehicle diagonally parked in the parking area of the storage room, the driver can park without worrying about the size of the parking area. At the same time, it is an object of the present invention to provide a loading / unloading device for a multi-storey parking lot that can set a parking rack and an parking area in an elevator to a suitable size without a redundant size.
