Next, the operation of the above embodiment will be described with reference to the flowchart showing the processing procedure of the microcomputer 26 in FIG. Now, it is assumed that the lift cage 1 is located above the vehicle storage position.

In this state, assuming that the vehicle is not in the warehousing position, it is determined in step of FIG. 6 whether the vehicle body detection switch BS is in the on state. At this time, since the vehicle is not in the warehousing position, the vehicle body detection switch BS is in the off state, and the process proceeds to step to display the vehicle warehousing possibility display device.
Output to 29, display device 29a of this display device 29 that can be stored in the vehicle
After turning on, return to the step.

In this standby state, when the vehicle enters the storage position and the vehicle body reaches the position of the vehicle body detection switch BS, the detection switch BS is turned on, and the process shifts from step to step.

In this step, it is determined whether or not any one of the photoelectric detectors R _{1 to} R ₃ of the rear side position detecting means 21 detects the wheel of the vehicle. Immediately after the vehicle detection switch BS is turned on, because the wheel does not reach the photoelectric detector R ₁ to R _3, the process proceeds to step outputs a forward display command to the display device 29, advancement of the device 29 The display 29b is turned on and the storage-ready display 29 is turned off.

After that, the front wheel of the vehicle is the photoelectric detector of the rear position detecting means 21.
When the R ₃ position is reached, the process moves from step to step, and it is determined whether or not any of the photoelectric detectors F _{1 to} F ₃ of the front side position detection means 20 detects the wheel of the vehicle.
At this time, when the front wheels of the vehicle have not reached the front side position detecting means 20, the process proceeds to the step and the forward traveling indicator.
After the lighting state of 29b is continued, the process returns to the step, and when the front wheel of the vehicle is detected, the process proceeds to the step.

In this step, the photoelectric detectors F ₁ and R ₁ , F ₂ and R ₂ , F ₃ which form a pair of the front side position detection means 20 and the rear side position detection means 21.
It is determined whether or not any one of R ₃ and R ₃ is on at the same time. At this time, assuming that the wheel base of the vehicle is equal to the distance between the front position detecting means 20 and the rear position detecting means 21, when the front wheel of the vehicle reaches the photoelectric detector F ₁ of the front position detecting means 20, The rear wheel is at the position of the photoelectric detector R ₃ of the rear side position detection means 21, and the photoelectric detector R ₁ does not detect the rear wheel, so the process proceeds to step, and the front side position detection means 20 and the rear side position are detected. The photoelectric detectors that detect the wheels of the detection means 21 are compared to determine whether the vehicle is the front side or the rear side with respect to the regular stop position. At this time,
Since the vehicle is on the rear side with respect to the regular stop position, the process proceeds to the step and the forward indicator 29b continues to be lit.

Then, when the vehicle further advances and the front wheels reach the photoelectric detection switch F ₂ of the front side position detection means 20, the rear wheels also reach the photoelectric detection switch R ₂ of the rear side position detection means 21,
Since the pair of photoelectric detection switches F ₂ and R ₂ both detect the wheel, the step moves from step to step.

In this step, a stop command is output to the display device 29,
The stop indicator 29c of the display device 29 is turned on and the forward indicator 29b is turned off, and then the process proceeds to step. In this step, it is determined whether or not a predetermined time (for example, about 1 minute) has elapsed. This determination is for confirming again whether or not the stop position is a regular stop position when the vehicle is stopped after the stop indicator 29c lights up, and the predetermined time has not elapsed. Sometimes, go back to the step. At this time, the vehicle moves too far and the front-back position detection means
20 photoelectric detectors F ₃ detect the front wheels and rear position detecting means 21
When the photoelectric detector R ₁ is in a state of detecting the rear wheels, the process moves from step to step, and since the stop position of the vehicle is on the front side with respect to the regular stop position, the process moves to step and the display device 29 is displayed. A backward display command is output, the backward indicator 29d of the display device 29 is turned on, and the stop indicator 29c is turned off, and then the process returns to the step.

On the other hand, when the vehicle is stopped at the regular stop position,
Repeat steps (1) to (5) after a lapse of a predetermined time, and after confirming that the driver of the vehicle has exited, move to the storage position (i.
It is determined whether or not the data indicating the column, the j-th column) has been input. If the data has not been input, the process waits until the data is input, and when the data has been input, the process proceeds to step a.

In this step a, a reverse rotation drive command is output to the hoisting machine drive circuit 28, whereby the hoisting machines 7a and 7b are reversely driven to lower the elevating cage 1. Then step b
Then, it is determined whether or not the elevating cage 1 has landed on the storage position surrounding the vehicle. Here, when the elevating cage 1 is not landed, the process returns to step a, and when landed, the process proceeds to step c.

In step c, a support position drive command is output to the electric motor drive circuit 27, and in response to this, the electric motor drive circuit 27 is output.
At 27, after the rotation support arm 9a is moved to the support position, the rotation support arm 9b is moved to the support position so that the vehicle body between the front and rear wheels of the vehicle can be supported.

Then, the process shifts to a step, and it is determined whether or not the support position detection switch Sb _{2 of the} rotation support arm 9b is turned on. This determination is to determine whether or not the movement of the rotation support arms 9a and 9b to the support position has been completed, and when the movement to the support position has not been completed, wait until the movement is completed and move. Is completed, the process proceeds to step to output a raising drive command to the hoisting machine drive circuit 28. In this way, when the raising drive command is output to the hoisting machine drive circuit 28, the hoisting machine 7a, 7
Drive b forward to raise the elevator cage 1. As the lift cage 1 is raised, the elastic bodies 12 of the rotation support arms 9a and 9b come into contact with the lower surface of the vehicle body between the front and rear wheels of the vehicle to support the vehicle and raise the vehicle to an arbitrary i stage.

Next, in step, it is judged whether or not the lift cage 1 has reached a position where the carriage 16 can enter a position slightly above the arbitrary i-th stage, that is, below the vehicle supported by the lift cage 1. Wait until it arrives, and when it arrives, move to step.

In this step, as shown in FIG. 4, the carriage 16 is positioned and stopped under the vehicle by an appropriate driving means. When the positioning of the dolly 16 is completed, the process proceeds to step, and the hoist reverse drive command is issued to the hoist drive circuit 28.
Is output to lower the elevator cage 1. Next, the process proceeds to step, and it is determined whether or not the elevator cage 1 has landed on the carriage 16. If it is not landed, the process returns to step. A return command for returning the movable support arms 9a and 9b to the storage position is output to the electric motor drive circuit 27, whereby the electric motor drive circuit 27 reverses the electric motor 11a to move the rotation support arm 9a to the storage position. When the storage position detection switch Sa ₁ is turned on, the electric motor 11b is reversely rotated to move the rotation support arm 9b to the storage position, and when the storage position detection switch Sb ₁ is turned on, step b And outputs a forward rotation drive command to the hoisting machine drive circuit 28 to raise the hoisting machines 7a and 7b by one step to the hoisting machine drive circuit 28, and after raising the hoisting cage 1, the process proceeds to step c, 16 trolleys equipped with It is moved to the position stored in.

Here, the processing of step and corresponds to the vehicle position determining means, and the processing and display device 29 of step and corresponds to the displaying means.

Next, in order to take out the vehicle stored in the multi-level parking device, first, after confirming that the vehicle does not exist at the vehicle storage position, the storage display 31 indicates the storage position of the vehicle.

As a result, the shipping process of FIG. 7 is executed. That is, first in step, it is determined whether or not the lifting cage 1 is positioned above the designated shipping stage. If the lifting cage 1 is positioned below, the process proceeds to step and the hoist drive circuit 28 is operated. An ascending command is output to elevate the elevating cage 1 to a position one step above the exit stage.

When the elevating cage 1 is stopped above the exit stage, the process moves from step to step, and the dolly carrying the outgoing vehicle is installed.
16 is traversed and positioned underneath the lifting cage 1, and then the process proceeds to a step to determine whether or not the positioning of the carriage 16 is completed. When the positioning is not completed,
Wait until the completion, and when the positioning is completed, move to the step and set the hoist drive circuit 28 to the hoist 7
The descending commands of a and 7b are output, and the hoisting machines 7a and 7b are driven in reverse to lower the elevating cage 1.

Next, in step S16, the lifting cage 1 is moved by the carriage 16
Determine whether you have landed on the top, and if you have not landed,
When returning to the step and landing, the step moves to the step.

In this step, a support position movement command is output to the electric motor drive circuit 27, the electric motor 11a is normally driven to move the rotation support arm 9a to the support position, and the support position detection switch Sa ₂ is turned on. Then, the drive of the electric motor 11a is stopped and the electric motor 11b is driven in the forward direction to move the rotation support arm 9b to the support position.

Next, move to the step, and the support position detection switch
It is determined whether or not Sb ₂ is in the on state, and when it is in the off state, it waits until it is in the on state, and when it is in the on state, it moves to step.

In this step, a slight ascending command is output to the hoisting machine drive circuit 28, the hoisting machines 7a and 7b are driven in the forward direction, and the lifting cage 1 is supported by the turning support arms 9a and 9b to support the vehicle body of the vehicle. The vehicle is lifted from the top of the bogie 16 to a position where it is levitated.

Next, the process proceeds to step, the carriage 16 is moved to a predetermined storage position and returned, and it is determined in step whether or not the return of the carriage 16 is completed. At this time, if the carriage 16 has not moved to the predetermined storage position and has not returned yet, wait until it returns,
When the movement is restored, the process goes to step to output a descending command for lowering the elevating cage 1 to the hoisting machine drive circuit 28, and lowering the elevating cage 1 while supporting the vehicle.

Next, the process proceeds to step, and it is determined whether or not the elevator cage 1 has landed at the loading / unloading position. If not, the process returns to step, and if landed, the process proceeds to step.

In this step, like step a in FIG. 6,
The rotation support arms 9a and 9b are returned to the storage position, and then the step moves to move the lift cage 1 upward so that the door of the vehicle can be opened and closed. Then, the step moves to the step,
