A voice alarm or the like is issued from the operation panel 1 provided near the entrance / exit, or an output section provided near the control panel 1, and control such as stopping the device is performed by the control device 25 provided in the multi-storey parking lot A.

The operation of the multi-storey parking lot A equipped with such an alarm device will be described. First, the door covering the front surface of the operation panel 1 is inserted and the door opening / closing switch 2 is operated to open the door. A blue lamp 6 indicating that the operation is “permitted” is lit on the operation panel 1 which is thus opened and the door can be used. Based on this lighting, the ten key 4 on the operation panel 1 is pressed to advance the operation. When the registered pallet number is designated, the designated pallet number is digitally displayed on the display unit 5. Then, when the operation button 3 is pressed, the pallet P is automatically driven to land in front of the entrance / exit of the multistory parking lot A, and the shutter 17 closing the entrance / exit of the multistory parking lot A at the time of landing. Open. From this time, the vehicle can be mounted on a pallet, and the red lamp 7 illuminating that allows the garage to enter and exit is turned on. By confirming that the red lamp 7 is lit, the next user can wait until the previous person has finished entering and leaving, and when the red lamp 7 is lit. The operation panel 1 cannot be operated to start the next warehousing operation. When the vehicle is mounted on the pallet P and the driver exits the multilevel parking lot A and presses the return button 9, the pallet P is automatically driven and returns to its original position, and the shutter 17 is closed at the same time. To do. Reference numeral 12 is a reset button for operating the stopped device. Each operation unit provided on the operation panel 1 is connected to a signal processing unit 16 such as a sequencer installed in the operation panel 1, and the signal processing unit 16 is further provided in the multi-storey parking lot A.
