  "abstract": "A transport device transports a plurality of trays of different types on which articles can be placed. The transport device includes a tray identification sensor that identifies the types of trays, and protrusion detection sensors that detect articles that are placed protruding from the trays. The tray identification sensor identifies the types of trays by detecting the characteristics of the trays. The protrusion detection sensors detect the articles according to the types of the trays identified by the tray identification sensor.",
