(Operation) When loading a car, as shown in FIGS. 1 and 2, the drive device 12 is driven in advance to call the empty storage tray 6 to the top of the parking facility, and the movable walking step 16 is performed. After tilting from the position indicated by the chain double-dashed line to the position indicated by the solid line, the driver enters the vehicle from the entrance (out) slot 15 and stores it in the empty storage tray 6. Next, as shown in FIG. 4, the pantograph mechanism 43 is actuated in the ascending direction, and the upper pedestal 40, which had been at the two-dot chain line position until then, is elevated to the solid line position to form the rotating device 37. The friction roller 45 attached to the geared motor 44 is pressed against the lower surface of the circular rail 25 fixed to the back surface of the turning tray 23, and at the same time, on the holding table 46 provided at the end of the upper frame. The carrying plate 47 pushes up the unlock roller 32 mounted on the intermediate actuating lever 30 of the lock mechanism 27 against the spring force of the coil spring 31, whereby the actuating levers 28, 28 locking the swivel tray 23 move downward. It is pushed down and unlocked.

Therefore, when the geared motor 44 of the rotary drive mechanism 48 is driven, the rotation of the friction roller is transmitted to the circular rail by the contact friction force between the friction roller 45 and the circular rail 25, and the swivel tray 23 is centered on the center post shaft 26. Further, while being kept guided by the fall prevention roller 34 and kept horizontal, it is rotated 180 °, for example, clockwise (or counterclockwise). Therefore, the vehicle accommodated in the storage tray 6 by the forward movement can be unloaded by the forward movement, and then the lowering operation of the pantograph mechanism 43 lowers the upper pedestal 40 from the solid line position to the two-dot chain line position. At the same time that the contact frictional force between the circular rail 25 and the circular rail 25 is released, the elastic load of the carrier plate 47 and the unlock roller 32 is released, and the intermediate actuating lever 30 moves the coil spring 31 in the counterclockwise direction in FIG. The pulling tray returns to the standing state from the tilted state and locks the swivel tray 23.

Next, as described above, when the vehicle for storing is housed in the storage tray 6, the vehicle is driven by the pantograph mechanism 43.
And the rotating device 37 rotates 180 ° so that the goods can be taken out forward. By lowering the upper pedestal 40, the pantograph mechanism and the rotating device deviate from the tray circulation traveling path, and the circulation operation can be performed. To do
If the empty storage tray 6 closest to the entry / exit opening 15 is called, the automatic vehicle-mounted tray can be placed in any desired location.

In the above embodiment, the case where the vehicle is stored has been described, but when the vehicle is stored, the driving progress at the time of storage may be reversed, and thus detailed description will be omitted.

(Effects of the Invention) Since the present invention is constructed as described above, it has the effects described below.

(1) In order to move the car in and out, the car can be moved forwards and then stored in the storage tray, and then the swivel tray can be rotated 180 ° to move out the car forwards.
