Abstract: A conveyor-type three dimensional parking system which comprises a storage structure having an entrance port and an exit port. A conveyor assembly is built into the storage structure for holding a plurality of motor vehicles. A pair of gates are provided to cover the entrance port and the exit port of the storage structure. A facility, operated by each driver is for actuating the entrance gate to open, so that each driver can drive their motor vehicle through the entrance port and into the conveyor assembly in the storage structure. A mechanism, operated by each driver, is for actuating the exit gate to open, so that each driver can retrieve their motor vehicle from the conveyor assembly and then drive out through the exit port of the storage structure.
